Description

The present invention provides a linear body for attaching a corrugated tube having an opening continuous in the longitudinal direction and capable of overlapping and closing overlapping portions in the vicinity of the opening end to the linear body. The present invention relates to a jig for attaching a corrugated tube, a method for inserting a linear body into a corrugated tube, and a method for adjusting the angle of the attachment jig when inserting a linear body into a corrugated tube.

Conventionally, when laying an electric wire or the like, the electric wire or the like is inserted into a protective pipe such as a corrugated pipe. Since the corrugated tube is tubular, in order to insert the electric wire through such a tubular member, it is necessary to sequentially feed the electric wire from the end. However, this task was not always easy.

On the other hand, there is a method in which a part of the corrugated tube is cut along the longitudinal direction and an electric wire is inserted through the notch. In this case, it is not necessary to feed the electric wire in the longitudinal direction.

As a method of attaching such a corrugated tube having an opening to a linear body such as a power cable, for example, a corrugated tube with a lock having a linear body guide portion, a tube guide portion, and a locking holding portion is attached. A jig has been proposed (Patent Document 1).

Further, there is a corrugated tube mounting jig with a lock having a path regulating member protruding inward from an expanded portion or a tubular portion (Patent Document 2).

Further, it is a fitting jig that fits the fitting concave portion and the fitting convex portion of the opening of the corrugated tube, and the tongue-shaped piece extends in the circumferential direction at the same height as the valley portion and fits into the facing portion. There is an exterior jig for a corrugated tube (Patent Document 3).

However, the conventional jig only considers opening the corrugated tube and attaching the corrugated tube to the linear body, and after attaching the corrugated tube to the linear body, restores the corrugated tube to its original state. It wasn't always enough to do the closing work.

For example, an overlapping corrugated tube having an opening formed along the longitudinal direction is partially overlapped in the circumferential direction at the opening. In this case, even after the inner overlapping portion arranged inside the opening and the outer overlapping portion arranged outside are attached to the striatum, the inner overlapping portion is on the inside and the outer overlapping portion is on the outside. Need to be placed.

However, in the conventional jig, when the corrugated pipe is opened, attached to the linear body, and then the corrugated pipe is closed again, the striatum is sandwiched between the above-mentioned inner overlapping portion and the outer overlapping portion. , The arrangement of the inner overlapping portion and the outer overlapping portion is reversed, the inner overlapping portion is on the outside, and the outer overlapping portion is arranged on the inner side, which may cause wrapping. If this happens, the striatum may not be inserted properly, or the surface of the striatum may be scratched. In addition, unintentional opening of the corrugated pipe may cause the linear body inside to pop out or foreign matter to enter the inside.

The present invention has been made in view of such a problem, and when the striatum is attached to the wrap type corrugated tube, the striatum can be easily inserted without sandwiching the striatum. , A jig for attaching the corrugated tube to the linear body that can properly overlap the inner overlapping part and the outer overlapping part after attaching to the linear body, the linear body to the corrugated tube It is an object of the present invention to provide an insertion method and a method for adjusting the angle of a jig for attaching the linear body insertion portion with respect to the axis of the expanded portion of the corrugated tube guide portion when the linear body is inserted into the corrugated pipe.

In order to achieve the above-mentioned object, the first invention is a linear corrugated tube having an opening and having an overlapping portion in which the outer overlapping portion and the inner overlapping portion are overlapped with each other in the vicinity of the opening. It is a mounting jig to be attached to the corrugated pipe guide portion, and includes a corrugated pipe guide portion and a linear body insertion portion. The corrugated pipe guide portion is covered with the corrugated pipe by expanding the corrugated pipe to the linear body insertion portion. The linear body insertion portion is a portion for guiding, and the linear body insertion portion is a portion for covering the linear body with an expanded corrugated tube. The corrugated tube guide portion is composed of a pair of base portions and an expanded portion, and the base. The portions are formed in a plate shape so as to face each other, the expanded portion projects outward substantially symmetrically with a predetermined size from the base portion, and the upper end of the linear body insertion portion opens. It has a structure formed by the inner U-shaped member and the outer U-shaped member, and the outer U-shaped member is covered on the outer side of the inner U-shaped member to form a double cylinder. A notch is formed in the middle of the outer U-shaped member in the axial direction from one upper edge of the opening of the U-shaped member to the axis of the expanded portion of the corrugated pipe guide portion. On the other hand, it is a jig for attaching a corrugated tube to a linear body, characterized in that the axis of the inner U-shaped member of the linear body insertion portion is formed at a predetermined angle.

One side wall portion of the inner U-shaped member and one side wall portion of the outer U-shaped member are connected to each other by a connecting portion, and the inner U-shaped member and the outer U-shaped member are excluded except for the connecting portion. The facing surfaces of the shaped members may be arranged so as to be separated from each other.

The angle formed by the axis of the expanded portion of the corrugated tube guide portion and the axis of the outer U-shaped member of the linear body insertion portion may be included in the range of 30 ° to 60 °.

The expanded portion is a plate-shaped member, and the angle formed by the base portion of the corrugated pipe guide portion and the expanded portion may be formed in the range of 75 ° to 105 °.

The expanded portion may have a hollow or solid substantially semicircular cross section.

A linear body can be held inside the inner U-shaped member, and an outer overlapping portion can be arranged on the outer periphery of the outer U-shaped member on the opposite side of the cut portion in front of the cut portion. , The inner overlapping portion may be arranged between the outer U-shaped member and the inner U-shaped member on the notch side.

When the inner overlapping portion passes through the notch portion of the outer U-shaped member, the cut portion switches the arrangement of the inner overlapping portion of the corrugated tube from the outside to the inside of the outer U-shaped member. The opening size of the opening of the outer U-shaped member differs before and after the notch, and the opening size of the notch is relative to the opening on the rear side of the notch. The opening size on the front side may be large.

The inner U-shaped member may be formed in a tapered shape toward the tip.

The tip of the inner U-shaped member may be formed so as to project forward from the tip of the outer U-shaped member.

The corrugated pipe guide portion and the linear body insertion portion are formed separately, and at the connecting portion between the corrugated pipe guide portion and the linear body insertion portion, the axis of the corrugated pipe guide portion and the linear body are formed. The angle of the axis of the insertion portion may be changeable.

Therefore, when the corrugated tube is closed, it is possible to prevent the inner overlapping portion from becoming the outside of the outer overlapping portion. Further, since the striatum is arranged inside the inner U-shaped member of the linear body insertion portion, and the corrugated tube and the striatum are arranged apart from each other in the inner U-shaped member, the striatum is arranged. It is possible to prevent the body from being pinched.

Further, the inner U-shaped member and the outer U-shaped member are connected by one side wall portion, and the facing surfaces of the inner U-shaped member and the outer U-shaped member are arranged so as to be separated from each other except for the connecting portion.

If it is possible to secure a space in which the inner overlapping portion can be arranged in front of the notch portion between the inner U-shaped member and the outer U-shaped member, the inner U-shaped member and the outer U-shaped member can be formed. It may be connected by the other side wall portion.

Further, if the angle between the axis of the expanded portion of the corrugated pipe guide portion and the axis of the linear body insertion portion is in the range of 30 ° to 60 °, it is easy to move the corrugated pipe from the corrugated pipe guide portion to the linear body insertion portion. You can transfer to. The angle formed by the axis is preferably 40 ° to 50 °.

Further, if the expansion portion is a plate-shaped member and the angle between the base portion of the corrugated pipe guide portion and the expansion portion is formed in the range of 75 ° to 105 °, the corrugated pipe must be reliably expanded. Can be done. The angle is preferably 80 ° to 100 °.

Further, if the expanded portion has a hollow or solid semicircular arc-shaped cross section, the shape of the inner surface of the corrugated pipe corresponds to the shape of the expanded portion, so that the expanded portion is brought into contact with the corrugated pipe in a wider range. The corrugated tube can be expanded efficiently.

Further, the linear body can be held inside the inner U-shaped member, and the outer overlapping portion can be arranged on the outer periphery of the outer U-shaped member on the opposite side of the cut portion in front of the cut portion. If the inner overlapping portion can be arranged between the U-shaped member and the inner U-shaped member, the linear body can be surely arranged inside the corrugated tube.

Further, by increasing the opening size of the outer U-shaped member on the front side of the notch with respect to the opening size of the outer U-shaped member on the rear side of the notch, the inner overlapping portion is surely inner U-shaped. It can be guided between the shaped member and the outer U-shaped member.

Further, since the inner U-shaped member is formed in a tapered shape toward the tip, the inner overlapping portion can be more reliably guided to the inside of the outer overlapping portion.

Further, by forming the tip of the inner U-shaped member so as to protrude forward from the tip of the outer U-shaped member, the inner overlapping portion is bent in the vicinity of the tip of the corrugated pipe, and the outer overlapping portion is formed. It is possible to suppress stacking.

Further, since the corrugated pipe guide portion and the linear body insertion portion are formed as separate bodies, the axial line and the linear body insertion portion of the corrugated pipe guide portion are formed at the joint portion between the corrugated pipe guide portion and the linear body insertion portion. You can change the angle of the axis of. Therefore, it can be adjusted to an appropriate angle according to the type or amount of the linear body.

Further, the corrugated pipe guide portion and the linear body insertion portion are separately configured, and the corrugated pipe guide portion and the linear body insertion portion are joined by either adhesion, fusion or mechanical connection. Therefore, at the time of use, both can be joined at an appropriate angle according to the type or amount of the linear body.

Further, at least one or both of the inner U-shaped member and the outer U-shaped member, or the outer U-shaped member and the base portion of the corrugated pipe guide portion may be integrally formed. For example, if the inner U-shaped member and the outer U-shaped member are integrally molded in this way, the number of parts can be reduced and at the same time the corrugated pipe mounting jig can be easily assembled.

Further, if the corrugated tube guide portion and the linear body insertion portion are made of a resin material or a metal material, the manufacturability is excellent and the required rigidity can be secured.

(First Embodiment)
Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a perspective view showing the mounting jig 1, FIG. 2 is a side view showing the mounting jig 1, FIG. 3 is a plan view showing the mounting jig 1, and FIG. 4A is A in FIG. -A line sectional view, FIG. 4 (b) is a BB line sectional view of FIG.

The attachment jig 1 is a jig for attaching a corrugated tube to a linear body, and is mainly composed of a corrugated tube guide portion 3 and a linear body insertion portion 5. The corrugated pipe guide portion 3 is a portion where a corrugated pipe, which will be described later, is expanded and covered to guide the corrugated pipe to the linear body insertion portion 5. The linear body insertion portion 5 is a portion for covering the linear body with the expanded corrugated tube.

More specifically, the corrugated tube guide portion 3 is composed of a pair of base portions 7 and an expansion portion 9. The base portion 7 is formed in a plate shape so as to face each other. The expanding portion 9 is formed so as to project outward substantially symmetrically from each base portion 7 with a predetermined size.

As shown in FIG. 4B, the expansion portion 9 is a plate-shaped member. Here, it is desirable that the angle (D in the figure) formed by the base portion 7 and the expansion portion 9 of the corrugated pipe guide portion 3 is formed in the range of 75 ° to 105 °. By doing so, when the corrugated pipe described later is covered, the corrugated pipe can be efficiently expanded. In the example shown in the figure, the angle formed by the base portion 7 and the expansion portion 9 is 90 °.

The shape of the expanded portion 9 is not limited to the example shown in FIG. 4 (b). For example, as shown in FIG. 5A, the expanded portion 9 may have a solid substantially semicircular cross-sectional shape. Alternatively, as shown in FIG. 5B, the expanded portion 9 may have a hollow substantially semicircular cross-sectional shape. If the outer surface of the expanding portion 9 is arcuate, the shape of the expanding portion 9 corresponds to the shape of the inner surface of the corrugated pipe. Therefore, when the expanding portion 9 is covered with the corrugated pipe and expanded, the expanding portion 9 is expanded. The corrugated tube can be efficiently held from the inner surface. In the following description, an example in which the expansion portion 9 has a plate shape is shown. When the cross-sectional shape of the expansion portion 9 is a hollow shape, the cross-sectional shape may be a rectangle or a parallelogram. In this way, by making the cross-sectional shape a contour shape of a predetermined closed curve such as a rectangle or a parallelogram, the rigidity of the expanding portion 9 is increased and the shape of the expanding portion 9 is stabilized.

The linear body insertion portion 5 is formed by an inner U-shaped member 13 having an open upper end portion and an outer U-shaped member 15 having an open upper end portion. That is, the linear body insertion portion 5 has a structure in which the outer U-shaped member 15 is crowned on the outer side of the inner U-shaped member 13 to form a double cylinder (double U-shaped structure). The inner U-shaped member 13 and the outer U-shaped member 15 are formed in substantially the same shape in the axial direction (vertical direction in FIG. 3), respectively.

Here, one side wall portion of the inner U-shaped member 13 and one side wall portion of the outer U-shaped member 15 are connected to each other by a connecting portion 19. Further, the side wall portion on the opposite side of the connecting portion 19 is not connected to the inner U-shaped member 13 and the outer U-shaped member 15.

At this time, it is desirable that the facing surfaces of the inner U-shaped member 13 and the outer U-shaped member 15 are arranged with a gap so as to be separated from each other at the portion other than the connecting portion 19. For example, on the opposite side of the connecting portion 19, the side wall portions of the inner U-shaped member 13 and the outer U-shaped member 15 are separated from each other. Further, the lower surface of the inner U-shaped member 13 and the lower surface of the outer U-shaped member 15 are separated from each other. That is, the radius of curvature of the curved portion of the U-shaped bottom of the inner U-shaped member 13 is smaller than the radius of curvature of the outer U-shaped member 15.

As shown in FIG. 2, the inner U-shaped member 13 (or the outer side) of the linear body insertion portion 5 with respect to the axis (direction from the upper right to the lower left in FIG. 2) of the expansion portion 9 of the corrugated pipe guide portion 3. The axis (left-right direction in FIG. 2) of the U-shaped member 15) is formed at a predetermined angle. More specifically, the angle formed by the axis of the expansion portion 9 of the corrugated pipe guide portion 3 and the axis of the inner U-shaped member 13 (or outer U-shaped member 15) of the linear body insertion portion 5 (C in the drawing). Is preferably included in the range of 30 ° to 60 °.

That is, the corrugated tube guide portion 3 has a substantially triangular shape in a side view, and is arranged above the linear body insertion portion 5 as a whole. The corrugated tube guide portion 3 is formed so that the height decreases from the rear end portion of the mounting jig 1 toward the front. Here, the front of the mounting jig 1 is the end side opposite to the corrugated pipe guide portion 3, and is the left side of FIG. If the angle between the corrugated pipe guide portion 3 and the linear body insertion portion 5 is appropriate, the corrugated pipe described later can be easily transferred from the corrugated pipe guide portion 3 to the linear body insertion portion 5.

A notch 17 is formed downward from the upper edge of one side wall of the opening 11 of the outer U-shaped member 15. More specifically, the outer U-shaped member 13 is a side wall portion on the opposite side of the connecting portion 19 to the inner U-shaped member 13, and the outer U-shaped member 13 and the outer U-shaped member 15 are not connected to each other. A notch 17 is formed in the character member 15. The cut portion 17 is formed only in the outer U-shaped member 15 and not in the inner U-shaped member 13.

The notch portion 17 is provided near the lower end of the expansion portion 9 of the corrugated pipe guide portion 3. More specifically, the notch portion 17 is arranged slightly in front of the mounting jig 1 with respect to the lower end portion of the expansion portion 9. That is, the lower end of the expansion portion 9 intersects the linear body insertion portion 5 at a position slightly distant from the front end of the linear body insertion portion 5, and the linear body insertion portion 5 is in front of the expansion portion 9. It is formed in substantially the same shape.

Here, it is desirable that the corrugated tube guide portion 3 and the linear body insertion portion 5 are made of a resin material or a metal material. By doing so, the corrugated tube guide portion 3 and the linear body insertion portion 5 have appropriate rigidity, and the manufacturability is also good.

Further, the inner U-shaped member 13 and the outer U-shaped member 15 may be integrally formed. Alternatively, the outer U-shaped member 15 and the base portion 7 may be integrally formed. As described above, if at least one of the inner U-shaped member 13 and the outer U-shaped member 15 or the outer U-shaped member 15 and the base portion 7 of the corrugated pipe guide portion 3 is integrally molded, the manufacturing can be performed. It is easy and the number of parts can be reduced.

Next, the corrugated tube applied to the present invention will be described. FIG. 6A is a cross-sectional view showing a corrugated pipe 20 in a closed state, and FIG. 6B is a cross-sectional view showing a corrugated pipe 20 in an open state.

In the corrugated pipe 20, a plurality of peaks and valleys (not shown) extending in the circumferential direction are formed alternately at predetermined intervals in the direction of the pipe axis. In a cross section perpendicular to the longitudinal direction of the corrugated pipe 20, both ends of the corrugated pipe 20 in the circumferential direction overlap each other. One end side of the corrugated tube 20 in the circumferential direction is the inner overlapping portion 25, and the other end side is the outer overlapping portion 23. As described above, the corrugated tube 20 has an overlapping portion 21 in which the outer overlapping portion 23 and the inner overlapping portion 25 are overlapped with each other in the vicinity of the opening 27.

The corrugated pipe 20 has an opening 27 (see FIG. 6B) formed in the circumferential cross section of the corrugated pipe when the corrugated pipe is expanded. That is, the opening 27 is continuously formed in the pipe axis direction of the corrugated pipe 20.
Further, in a cross section perpendicular to the longitudinal direction of the corrugated pipe 20, both ends of the corrugated pipe 20 in the circumferential direction overlap each other. One end side of the corrugated tube 20 in the circumferential direction is the inner overlapping portion 25, and the other end side is the outer overlapping portion 23. As described above, the corrugated tube 20 has an overlapping portion 21 in which the outer overlapping portion 23 and the inner overlapping portion 25 are overlapped with each other in the vicinity of the opening 27.

In the cross section perpendicular to the longitudinal direction of the corrugated pipe 20, the corrugated pipe 20 is substantially circular in the closed state. From this state, the opening 27 of the corrugated tube 20 can be opened by opening and expanding the inner overlapping portion 25 and the outer overlapping portion 23 (arrow E in FIG. 6B). The cross-sectional shape of the corrugated pipe 20 is not limited to the illustrated example, and may have another cross-sectional shape as long as the inner overlapping portion 25 and the outer overlapping portion 23 are overlapped with each other at the overlapping portion 21. ..

Here, the inner overlapping portion 25 has a slightly larger radius of curvature than the outer overlapping portion 23. Therefore, when the corrugated tube 20 is closed, the inner overlapping portion 25 is arranged inside the outer overlapping portion 23 and overlapped, so that a pressing force is applied from the outer overlapping portion 23 to the inner overlapping portion 25. It works and is in close contact with each other to stabilize the shape.

On the other hand, in the state where the corrugated tube 20 is closed, the inner overlapping portion 25 and the outer overlapping portion 23 are arranged in the opposite positions, and the inner overlapping portion 25 is located outside the outer overlapping portion 23. If they are arranged and overlapped, the shape may not be stable, and there is a risk that an unintended opening or a pitch shift may occur in which the inner overlapping portion 25 does not match the tip position of the outer overlapping portion 23. Therefore, when closing the corrugated pipe 20, it is necessary to arrange the inner overlapping portion 25 inside the outer overlapping portion 23 and superimpose it.

Next, a method of inserting the linear body into the corrugated pipe 20 using the mounting jig 1 will be described. FIG. 7 is a side view showing a state in which the linear body 29 is inserted through the corrugated tube 20. 8 (a) is a sectional view taken along line FF of FIG. 7, FIG. 8 (b) is a sectional view taken along line GG of FIG. 7, and FIG. 9 (a) is a sectional view taken along line HF of FIG. FIG. 9 (b) is a sectional view taken along line I-I of FIG. 7. In FIG. 7, the corrugated pipe 20 is shown by a dotted line, which is a perspective view of the corrugated pipe 20.

First, if necessary, the linear body 29 to be inserted into the corrugated pipe 20 is fixed to a guide plate or the like. The linear body 29 may be at least one of a covered electric wire, an optical fiber cable, and a composite electric wire of an electric / optical fiber cable. Further, in the illustrated example, one linear body 29 is shown, but the linear body 29 may be a wire harness made of a plurality of wire rods.

Next, the corrugated pipe 20 having the superposed portion 21 that superimposes the outer superposed portion 23 and the inner superposed portion 25 on each other is pushed in while covering the corrugated pipe guide portion 3 (first step). More specifically, the opening 27 of the corrugated pipe 20 is directed downward, and the end portion of the corrugated pipe 20 is pushed in from the upper end of the corrugated pipe guide portion 3 (see FIG. 8A). At this time, a pair of expanding portions 9 are inserted into the inside through the opening 27 of the corrugated pipe 20. Therefore, the expanding portion 9 pushes the corrugated pipe 20 open, and the corrugated pipe 20 is expanded (see FIG. 8B).

At this time, while covering the corrugated pipe guide portion 3 with the corrugated pipe 20 so that the circumferential end portion of the corrugated pipe 20 on the side to be the inner overlapping portion 25 is arranged on the side where the notch portion 17 is formed. Push it in. That is, the inner overlapping portion 25 is expanded by the expanding portion 9 on the cut portion 17 side, and the outer overlapping portion 23 is expanded by the expanding portion 9 on the side where the cut portion 17 is not formed.

Next, the corrugated pipe 20 is moved from the corrugated pipe guide portion 3 to the linear body insertion portion 5 while the linear body 29 is inserted into the inner U-shaped member 13 of the linear body insertion portion 5. At this time, by passing the corrugated tube 20 through the notch 17 of the outer U-shaped member 15, the inner overlapping portion 25 can be moved from the outside to the inside of the outer U-shaped member 15 (second). Process).

More specifically, the end portion of the corrugated pipe 20 is moved from the corrugated pipe guide portion 3 to the linear body insertion portion 5 while being bent. At this time, the outer overlapping portion 23 is fed to the outside of the outer U-shaped member 15, and the inner overlapping portion 25 has a reduced diameter caused by the corrugated pipe being in a diameter-expanded state when passing through the notch portion 17. It is sent into the outer U-shaped member 15 by the elastic repulsive force (restoring force) to be tried (see FIG. 9A). The linear body 29 is linearly arranged inside the inner U-shaped member 13. Therefore, the linear body 29 is arranged inside the corrugated tube 20.

From this state, the corrugated tube 20 is further pushed in front of the linear body insertion portion 5, and the tip of the corrugated tube 20 is pushed out from the tip of the linear body insertion portion 5, so that the outer overlapping portion 23 is further pushed into the inner overlapping portion 25. Can be fitted with (see FIG. 9B). By feeding the corrugated tube 20 while moving the mounting jig 1 relative to the linear body 29, the corrugated tube 20 can be covered over substantially the entire length of the linear body 29 (third step). ..

Here, in the corrugated pipe 20, the inner overlapping portion 25 and the outer overlapping portion 23 are expanded without being overlapped between the time when the corrugated pipe 20 is pushed into the corrugated pipe guide portion 3 and the time when the corrugated pipe 20 is pushed out from the linear body insertion portion 5. It will be in the opened state. Further, as described above, in the state where the corrugated tube 20 is covered with the linear body insertion portion 5 (see FIG. 9A), the outer overlapping portion 23 is arranged outside the outer U-shaped member 15. Will be done. Further, the inner overlapping portion 25 is arranged inside the outer U-shaped member 15 and outside the inner U-shaped member 13.

Since the corrugated tube 20 tries to return from the expanded state to the closing direction by its own elastic force, the inner overlapping portion 25 is pressed against the outer surface of the inner U-shaped member 13, and the outer overlapping portion 23 is pressed. , Is pressed against the outer surface of the outer U-shaped member 15. Here, the inner U-shaped member 13 has a smaller diameter than the outer U-shaped member 15. Therefore, the inner overlapping portion 25 is located more inside (closer to the center) than the outer overlapping portion 23 with respect to the center of the cross section of the expanded corrugated pipe 20.

In this state, when the corrugated tube 20 is pushed forward from the tip of the linear body insertion portion 5, the outer overlapping portion 23 and the inner overlapping portion 25 overlap each other due to the restoring force of the corrugated tube 20. At this time, in the expanded state, the inner overlapping portion 25 located more inside is surely overlapped inside the outer overlapping portion 23. Therefore, it is possible to prevent the outer overlapping portion 23 and the inner overlapping portion 25 from being superposed on the inside and outside.

Further, the linear body 29 is arranged inside the inner U-shaped member 13. Therefore, in the expanded state, the outer overlapping portion 23 is located on the outer circumference of the outer U-shaped member 15 at a position away from the linear body 29. Therefore, when the corrugated pipe 20 is reduced in diameter from the expanded state, the inner overlapping portion 25 arranged along the inner U-shaped member 13 is located below the linear body 29. As a result, it is possible to prevent the vicinity of the tip portion of the outer overlapping portion 23 from coming into contact with the linear body 29. Therefore, the linear body 29 is not sandwiched between the inner overlapping portion 25 and the outer overlapping portion 23.

As described above, according to the present embodiment, even if the corrugated pipe 20 is a wrap type corrugated pipe in which the inner overlapping portion 25 and the outer overlapping portion 23 are overlapped, the corrugated pipe 20 can be easily expanded. , The linear body 29 can be accommodated inside the corrugated tube 20 from the opening 27.

Further, when the corrugated pipe 20 is returned to the original state after the corrugated pipe 20 is expanded and the linear body 29 is inserted, the inner and outer arrangements of the inner overlapping portion 25 and the outer overlapping portion 23 are reversed. There is no. Further, the tip positions of the inner overlapping portion 25 and the outer overlapping portion 23 can be substantially matched. Therefore, the internal linear body 29 can be reliably protected.

Further, when the expanding portion 9 is a plate-shaped member, if the angle formed by the base portion 7 of the corrugated pipe guide portion 3 and the expanding portion 9 is formed in the range of 75 ° to 105 °, the corrugated pipe 20 Can be reliably expanded when the corrugated tube 20 is inserted into the mounting jig 1. Further, the angle formed by the base portion 7 and the expanding portion 9 of the corrugated pipe guide portion 3 can be set in the range of 80 ° to 100 °, even if the elastic rebound force from the corrugated pipe is received at the time of expanding. It is desirable because the angle of the spread part is stable.

Further, if the expanding portion 9 has a hollow or solid substantially semicircular cross section, the inner surface shape of the corrugated pipe 20 corresponds to the outer surface shape of the expanding portion 9, so that the expanding portion 9 is provided with respect to the corrugated pipe 20. It is possible to make contact in a wider range, and the corrugated pipe 20 can be efficiently expanded.

Further, if the angle formed by the axis of the expanding portion 9 of the corrugated pipe guide portion 3 and the axis of the linear body insertion portion 5 is in the range of 30 ° to 60 °, the corrugated pipe 20 is pushed in when the corrugated pipe 20 is pushed in. Can be easily transferred from the corrugated tube guide portion 3 to the linear body insertion portion 5. Further, it is desirable that the angle formed by the two is 40 ° to 50 °. By doing so, the insertion resistance due to bending of the corrugated pipe 20 when the corrugated pipe 20 is transferred from the corrugated pipe guide portion 3 to the linear body insertion portion 5 can be appropriately controlled.

Further, the inner U-shaped member 13 and the outer U-shaped member 15 are connected only by one side wall portion, and at the other side wall portion, the inner U-shaped member 13 and the outer U-shaped member 13 are formed at the notch portion 17. The facing surfaces of the character-shaped member 15 are arranged so as to be separated from each other. Therefore, the inner overlapping portion 25 can be easily guided between the inner U-shaped member 13 and the outer U-shaped member 15.

In this way, the mounting jig 1 can hold the linear body 29 inside the inner U-shaped member 13, and in front of the cut portion 17, the outer U-shaped member 15 on the opposite side of the cut portion 17 If the outer overlapping portion 23 can be arranged on the outer circumference and the inner overlapping portion 25 can be arranged between the outer U-shaped member 15 and the inner U-shaped member 13, the linear body 29 can be surely corrugated. It can be placed inside 20.

(Second Embodiment)
Next, the second embodiment will be described. FIG. 10 is a plan view showing the mounting jig 1a. In the following description, the same reference numerals as those in FIGS. 1 to 9 will be given to the configurations that perform the same functions as those in the first embodiment, and duplicate description will be omitted.

The mounting jig 1a has almost the same structure as the mounting jig 1, but the structure of the outer U-shaped member 15 is different. In the mounting jig 1 described above, the dimensions of the openings 11 of the inner U-shaped member 13 and the outer U-shaped member 15 are substantially constant with respect to the longitudinal direction of the linear body insertion portion 5. On the other hand, in the mounting jig 1a, the opening size of the opening 11 of the outer U-shaped member 15 is different before and after the notch 17.

As shown in FIG. 10, in the mounting jig 1a, the front side (lower in the figure) of the notch 17 with respect to the opening dimension (J in the figure) of the opening 11 on the rear side (upper in the figure) of the notch 17. ) Has a large opening size (K in the figure). That is, the side wall portion of the outer U-shaped member 15 on the notch portion 17 side is formed so as to open outward on the front side of the notch portion 17. If the opening size of the outer U-shaped member 15 is widened on the front side of the cut portion 17, the opening size of the outer U-shaped member 15 on the front side of the cut portion 17 is not constant. It may have a tapered shape.

When the corrugated pipe 20 is pushed into the corrugated pipe guide portion 3 of the mounting jig 1a, the corrugated pipe 20 is expanded and expanded by the expanding portion 9 as described above. When the corrugated tube 20 is further pushed in the direction of the linear body insertion portion 5 from this state, the tip of the corrugated tube 20 shifts from the lower end of the expansion portion 9 to the linear body insertion portion 5.

Here, the expanding portion 9 projects outward from the base portion 7. Therefore, the lower end of the expansion portion 9 projects outward with reference to the base portion 7. On the other hand, as described above, the outer U-shaped member 15 is spread outward in front of the cut portion 17. That is, the side wall portion of the outer U-shaped member 15 in front of the notch portion 17 is located on the outside with respect to the base portion of the expansion portion 9 located behind the notch portion 17.

By doing so, when the corrugated tube 20 is pushed in the direction of the linear body insertion portion 5 and the tip of the corrugated tube 20 is transferred from the lower end of the expansion portion 9 to the linear body insertion portion 5, the inner overlap is performed. The tip of the portion 25 easily enters the inside of the outer U-shaped member 15 in front of the notch portion 17. Therefore, when passing through the cut portion 17, the inner overlapping portion 25 of the corrugated pipe 20 can be easily inserted by switching the arrangement from the outside to the inside of the outer U-shaped member 15.

According to the second embodiment, the same effect as that of the first embodiment can be obtained. Further, by opening the outer U-shaped member 15 on the front side of the cut portion 17 to the outside, the inner overlapping portion 25 is surely guided between the inner U-shaped member 13 and the outer U-shaped member 15. be able to.

(Third Embodiment)
Next, a third embodiment will be described. FIG. 11 is a plan view showing the mounting jig 1b. The mounting jig 1b has almost the same configuration as the mounting jig 1, but the mode of the inner U-shaped member 13 is different.

In the mounting jig 1b, the inner U-shaped member 13 is formed in a tapered shape that tapers toward the tip on the side where the cut portion 17 is formed. The starting point of the tapered shape is, for example, the vicinity of the notch portion 17.

When the corrugated pipe 20 is pushed into the corrugated pipe guide portion 3 of the mounting jig 1b, as described above, the corrugated pipe 20 is expanded by the expanding portion 9 and is expanded, and the expanding portion 9 is expanded. It shifts from the lower end to the linear body insertion portion 5. At this time, the inner overlapping portion 25 is guided to the inside of the outer U-shaped member 15 and moves forward along the inner U-shaped member 13.

Further, when the corrugated pipe 20 is pushed in and the corrugated pipe 20 is sent out in front of the linear body insertion portion 5, the corrugated pipe 20 is closed by overlapping the inner overlapping portion 25 and the outer overlapping portion 23 from the expanded state. To do. At this time, the inner overlapping portion 25 is pushed out in front of the linear body insertion portion 5 while being gradually reduced in diameter along the inner U-shaped member 13. Therefore, the inner overlapping portion 25 can be more reliably overlapped inside the outer overlapping portion 23.

According to the third embodiment, the same effect as that of the first embodiment can be obtained. Further, since the inner U-shaped member 13 is formed in a tapered shape toward the tip, the inner overlapping portion 25 can be more reliably guided to the inside of the outer overlapping portion 23. Therefore, when the corrugated tube 20 is returned to the original state, it is possible to prevent the inner and outer arrangements of the inner overlapping portion 25 and the outer overlapping portion 23 from being reversed.

(Fourth Embodiment)
Next, a fourth embodiment will be described. FIG. 12 is a plan view showing the mounting jig 1c. The mounting jig 1c has almost the same configuration as the mounting jig 1, but the mode of the inner U-shaped member 13 is different.

In the mounting jig 1c, the tip of the inner U-shaped member 13 is formed so as to project forward from the tip of the outer U-shaped member 15. That is, the inner U-shaped member 13 is longer than the outer U-shaped member 15, and the front end of the linear body insertion portion 5 is formed only by the inner U-shaped member 13.

When the corrugated pipe 20 is pushed into the corrugated pipe guide portion 3 of the mounting jig 1c, as described above, the corrugated pipe 20 is expanded and expanded by the expanding portion 9, and the expanding portion 9 is expanded. It shifts from the lower end to the linear body insertion portion 5. At this time, the inner overlapping portion 25 is guided to the inside of the outer U-shaped member 15 and moves forward along the inner U-shaped member 13.

At this time, if the inner overlapping portion 25 is not smoothly introduced between the outer U-shaped member 15 and the inner U-shaped member 13, the inner overlapping portion 25 is not introduced between the outer U-shaped member 15 and the inner U-shaped member 13. It may bend between 13 and 13.

Here, the gap between the outer U-shaped member 15 and the inner U-shaped member 13 is not so large. Therefore, if the inner overlapping portion 25 is bent between the outer U-shaped member 15 and the inner U-shaped member 13, the bending is caused between the outer U-shaped member 15 and the inner U-shaped member 13. There is a risk that it will not be possible to return to the original state. Alternatively, even if the bending can be restored, the tip position of the inner superimposing portion 25 is located from the tip position of the outer superimposing portion 23 in the arrangement of the tip positions of the outer superimposing portion 23 and the inner superimposing portion 25. There may be a misalignment of being placed behind.

Therefore, in this state, when the corrugated pipe 20 is further pushed in and the corrugated pipe 20 is sent out in front of the linear body insertion portion 5, the corrugated pipe 20 is in a state where the inner overlapping portion 25 is bent from the expanded state. As it is, it may be overlapped with the outer overlapping portion 23. Further, even if the bent state can be restored to the original state by continuing the bent state for a long time, there is a problem that the arrangement of the inner overlapping portion 25 and the outer overlapping portion 23 causes a pitch shift when both are overlapped.

On the other hand, in the mounting jig 1c, the tip of the inner U-shaped member 13 projects toward the tip side of the outer U-shaped member 15. Therefore, at the tip of the inner U-shaped member 13, the outer U-shaped member 15 is not arranged on the outer peripheral side of the inner U-shaped member 13, and the inner U-shaped member 13 is exposed to the outer surface. Therefore, even if the inner overlapping portion 25 is bent between the outer U-shaped member 15 and the inner U-shaped member 13, the inner U-shaped member 15 is released from the outer U-shaped member 15. Sufficient space is secured on the outside of the character-shaped member 13, and restrictions from the outside are released. For this reason, the bend is likely to return to its original state. Therefore, the inner overlapping portion 25 and the outer overlapping portion 23 can be appropriately overlapped. In addition, by returning the bend to the original position, the misalignment between the inner overlapping portion and the outer overlapping portion is eliminated.

Further, when the inner overlapping portion 25 protrudes toward the tip side from the outer U-shaped member 15, the outer overlapping portion 23 is also arranged on the inner U-shaped member 13, so that the corrugated tube 20 has a smaller diameter. Can be overlapped with, and can be inserted without biting the striatum.

According to the fourth embodiment, the same effect as that of the first embodiment can be obtained. Further, by forming the tip of the inner U-shaped member 13 projecting forward from the tip of the outer U-shaped member 15, the inner overlapping portion 25 is bent in the vicinity of the tip of the corrugated tube 20 and is outside. It is possible to suppress stacking on the overlapping portion 23.

(Fifth Embodiment)
Next, a fifth embodiment will be described. FIG. 13 is an exploded side view showing the mounting jig 1d. The mounting jig 1d has almost the same configuration as the mounting jig 1, but differs in that the corrugated tube guide portion 3 and the linear body insertion portion 5 are formed as separate bodies.

In the above-described embodiment, the outer U-shaped member 15 of the linear body insertion portion 5 and the base portion 7 of the corrugated pipe guide portion 3 are integrally formed, but the mounting jig 1d is a wire with the corrugated pipe guide portion 3. The body insertion portion 5 is formed as a separate body, and joint portions 31a and 31b are provided respectively. For example, the joint portion 31a is provided on the inner surface of the lower portion of the base portion 7, and the joint portion 31b is provided at a portion where the rear portion of the outer U-shaped member 15 projects upward.

14 (a) and 14 (b) are side views showing a state in which the corrugated pipe guide portion 3 and the linear body insertion portion 5 are joined, respectively. 14 (a) and 14 (b) are perspective views of the corrugated pipe guide portion 3, and the corrugated pipe guide portion 3 is shown by a dotted line.

The corrugated pipe guide portion 3 and the linear body insertion portion 5 are joined by the joining portions 31a and 31b. At this time, it is desirable that the corrugated pipe guide portion 3 and the linear body insertion portion 5 in the joint portions 31a and 31b are joined by, for example, adhesion, fusion, or mechanical connection. That is, the angle between the corrugated pipe guide portion 3 (the axis of the expansion portion 9) and the linear body insertion portion 5 (the axis of the inner U-shaped member 13 or the outer U-shaped member 15) is adjusted to adjust the corrugated pipe guide. The portion 3 and the linear body insertion portion 5 can be joined.

For example, in the example shown in FIG. 14A, the corrugated pipe guide portion 3 is joined with respect to the reference state (the state in which the lower end of the corrugated pipe guide portion 3 and the upper end of the linear body insertion portion 5 are joined substantially in parallel). The rear end is tilted downward to join the two. That is, the angle between the corrugated pipe guide portion 3 (the axis of the expansion portion 9) and the linear body insertion portion 5 (the axis of the inner U-shaped member 13 or the outer U-shaped member 15) is smaller than the reference state. Can be adjusted to be.

Similarly, in the example shown in FIG. 14B, the rear end of the corrugated pipe guide portion 3 is tilted upward from the reference state, and both are joined. That is, the angle between the corrugated pipe guide portion 3 (the axis of the expansion portion 9) and the linear body insertion portion 5 (the axis of the inner U-shaped member 13 or the outer U-shaped member 15) is large with respect to the reference state. Can be adjusted to be.

By doing so, the angle between the axis of the corrugated tube guide portion 3 and the axis of the linear body insertion portion 5 can be adjusted according to the type or amount of the linear body 29 to be inserted into the inside. That is, by such a method, the angle of the mounting jig 1d can be adjusted when the linear body 29 is inserted into the corrugated pipe 20.

In any case, the tip of the corrugated tube guide portion 3 (the tip of the expansion portion 9) is located at the upper end position of the linear body insertion portion 5 and is located at the notch portion 17 (or slightly behind the notch portion 17). Arranged like this. This is to ensure that the inner overlapping portion 25 of the corrugated pipe 20 expanded by the expanding portion 9 is guided to the notch portion 17.

If the joints 31a and 31b can be repeatedly attached and detached, the angle between the axis of the corrugated pipe guide portion 3 and the axis of the linear body insertion portion 5 depends on the type or amount of the linear body 29 to be inserted inside. Can also be changed. For example, if the joint portions 31a and 31b are hook-and-loop fasteners or the like, the corrugated pipe guide portion 3 and the linear body insertion portion 5 can be repeatedly attached and detached, so that the angles of both can be finely adjusted and different linear bodies 29 On the other hand, the mounting jig 1d adjusted to an appropriate angle can be used.

According to the fifth embodiment, the same effect as that of the first embodiment can be obtained. Further, the corrugated pipe guide portion 3 and the linear body insertion portion 5 are formed as separate bodies, and the joint between the corrugated pipe guide portion 3 and the linear body insertion portion 5 at the joint portions 31a and 31b is adhered, fused or bonded. By using either of the mechanical connections, the two can be joined at an appropriate angle depending on the type or amount of the linear body 29 at the time of use. As a mechanical connection method for enabling angle adjustment, the corrugated pipe guide portion 3 and the linear body insertion portion 5 are connected with a planar fastener, and the fixing position of both with respect to the planar fastener is changed or the pin is fixed. It can be realized by using a known fixing means such as a rotatable structure.

Further, if the joint portions 31a and 31b of the corrugated pipe guide portion 3 and the linear body insertion portion 5 are detachable, the axis and the linear body of the corrugated pipe guide portion 3 are formed according to the type or amount of the linear body. The angle of the axis of the insertion portion 5 can be changed to an appropriate angle.
