The configuration described in the embodiment can be employed as a structure for maintaining the combined state of the main body portion and the lid portion in the case. Moreover, the structure demonstrated by this embodiment can be employ | adopted also as a structure for maintaining two connectors in a united state. That is, the structure demonstrated here can be employ | adopted as a structure for maintaining those united states in vehicle mounting parts provided with the 1st main body part and 2nd main body part which can be united.

FIG. 1 is a schematic exploded perspective view of a wire 10 with a protector. The protector-equipped electric wire 10 includes an electric wire 12 and a protector 20.

Here, the protector-equipped electric wire 10 includes a plurality of electric wires 12. The plurality of electric wires 12 are accommodated in the protector 20 in a bundled state. In addition, in FIG. 1, the whole form in which the some electric wire 12 was bundled is shown. The plurality of electric wires 12 may be branched inside or outside the protector 20. An optical fiber cable or the like may be bundled together with the electric wire 12.

A terminal is attached to the end of the electric wire 12, and the terminal is inserted into the connector. By connecting the connector to a connector on the side of various electric devices in a vehicle or the like, the various electric devices are electrically connected via the protector-equipped electric wire 10. That is, the protector-equipped electric wire 10 is used as a wiring member in a vehicle.

The protector 20 protects the intermediate portion in the longitudinal direction of the electric wire 12, and includes a main body portion 22, an insertion side locking portion 30, and a receiving side locking portion 40.

The main body portion 22 includes a lid portion 28 as a first main body portion and an accommodating portion 24 as a second main body portion. And the accommodating space which can accommodate the electric wire 12 between them is formed when the accommodating part 24 and the cover part 28 unite | combine.

Here, the accommodating part 24 is a member formed by injecting molten resin into an injection mold, and has an elongated plate-like bottom part 24a and a pair of side wall parts erected on both sides of the bottom part 24a. 24b, and is formed in a square hook shape that opens at both ends thereof and on the opposite side of the bottom 24a. Both end portions of the bottom portion 24a protrude outward from the end portions of the side wall portions 24b. And while the longitudinal direction intermediate part of the electric wire 12 is accommodated in the accommodating part 24, the both end side part is extended to the both ends side outward of the accommodating part 24. As shown in FIG. At both ends of the accommodating portion 24, the electric wire 12 is fixed to the accommodating portion 24 by binding an adhesive tape or a binding band to both ends of the electric wire 12 and the bottom portion 24 a.

The lid portion 28 is a member formed by injecting molten resin into an injection mold, and is formed in an elongated plate shape that can close the opening on the side opposite to the bottom portion 24a in the housing portion 24. . And the lid | cover part 28 closes the opening on the opposite side to the bottom part 24a among the accommodating parts 24, is united with the accommodating part 24, and can be accommodated in the extending direction intermediate part of the electric wire 12. A housing space is formed.

However, the lid portion may be formed in a square hook shape. Moreover, when several electric wires branch in the middle, the opening etc. for drawing out the said branch part may be formed in the accommodating part or the cover part. Moreover, the accommodating part and the cover part may be bent on the way.

The insertion side locking part 30 is provided in the lid part 28, and the receiving side locking part 40 is provided in the storage part 24. Here, a plurality (three in this case) of receiving-side locking portions are provided on the upper edge portions of the outer surfaces of the pair of side wall portions 24b of the accommodating portion 24 at intervals along the extending direction of the upper edge portions. 40 is provided. In addition, a plurality of (here, three) insertion side locking portions 30 are provided at intervals along the extending direction of both side edges of the lid portion 28.

In addition, since the accommodating part 24 and the cover part 28 are made into the separate structure here, the receiving side latching | locking part 40 or the insertion side latching | locking part 30 is provided in each both sides. However, even if the housing portion and the lid portion are integrally formed with a mold, and one side portion of the housing portion and one side portion of the lid portion are connected so as to be openable and closable via a hinge portion made of a thin resin. Good. In such a case, a receiving side latching part or an insertion side latching part should just be provided only in the other side part of a storage part, and the other side part of a cover part. Here, the insertion side locking portion 30 is provided in the lid portion 28 and the receiving side locking portion 40 is provided in the housing portion 24, but this is not necessary. The lid portion may be regarded as the second main body portion, the receiving side locking portion may be provided on the lid portion, the receiving portion may be regarded as the first main body portion, and the insertion side locking portion may be provided on the receiving portion. .

2 is a perspective view of the insertion side latching portion 30, FIG. 3 is a cross-sectional view showing a state where the insertion side latching portion 30 is inserted into the reception side latching portion 40, and FIG. FIG. 6 is a front view showing a state in which an insertion side locking portion 30 is inserted into a portion 40.

The receiving side locking part 40 includes a pair of side parts 42 and a connecting part 44.

The pair of side portions 42 are formed in parallel on the outer surface which is the main surface of the side wall portion 24b. The extending direction of the pair of side portions 42 is a direction orthogonal to the upper edge portion of the side wall portion 24b. Further, the pair of side portions 42 are formed with a gap in the extending direction of the upper edge portion of the side wall portion 24b.

The connecting portion 44 is formed so as to connect the pair of side portions 42 at a position spaced from the outer surface of the side wall portion 24b.

Then, a rectangular hole-shaped insertion hole 46 surrounded by the outer surface of the side wall 24b, the pair of side portions 42 and the connecting portion 44 is formed. The insertion side locking portion 30 is inserted into the insertion hole 46.

In addition, the part by the side of the cover part 28 of the inward surface of the connection part 44 is formed in the inclined surface 44f which inclines outward toward the said cover part 28 side, and other parts are insertion side latching | locking parts. 30 is formed on a surface 45f facing outward along the insertion direction. These

inclined surfaces

44 f and 45 f are receiving-side contact portions that come into contact with the insertion-side locking portion 30 when the insertion-side locking portion 30 is inserted into the receiving-side locking portion 40.

The insertion side locking portion 30 is provided so as to protrude toward the housing portion 24 with respect to the lid portion 28 and has a locking protrusion 34 provided at the tip. More specifically, the insertion-side locking portion 30 includes a plate-like portion 32 extending from the lid portion 28 toward the accommodating portion 24, and a tip-side portion of one main surface (outward-facing main surface) of the plate-like portion 32. And a locking projection 34 projecting from the projection.

The plate-like portion 32 is formed in an elongated plate shape, and its width dimension is set to be the same as or smaller than the dimension between the pair of side portions 42 of the receiving-side locking portion 40. Moreover, the front-end | tip part of the plate-shaped part 32 is formed in the shape which becomes gradually narrow toward the front end side. Further, the thickness dimension of the plate-like part 32 is set to be the same as or smaller than the dimension between the outer surface of the side wall part 24 b and the connecting part 44. Further, the projecting dimension of the plate-like portion 32 is set to a size exceeding the lower edge portion of the connecting portion 44 of the receiving side locking portion 40 in a state where the accommodating portion 24 and the lid portion 28 are combined. As a result, the insertion side locking portion 30 can be inserted into the insertion hole portion 46 until the distal end portion of the insertion side locking portion 30 protrudes downward beyond the insertion hole portion 46.

The locking protrusion 34 is formed so as to protrude outward at the center in the width direction of the tip of one main surface (outward surface) of the plate-like portion 32. The locking projection 34 is formed with an inclined surface 34 f that sequentially increases the protruding dimension of the locking projection 34 from the distal end side to the proximal end side of the plate-like portion 32. That is, the locking projection 34 is formed in a shape that gradually decreases in height toward the tip side of the plate-like portion 32. A surface 35f facing inward along the extending direction of the plate-like portion 32 is formed on the base end side of the plate-like portion 32 in the inclined surface 34f.

Thereby, when inserting the insertion side latching | locking part 30 in the insertion hole 46, the latching protrusion 34 can carry out the outward elastic deformation of the connection part 44 gradually. Moreover, when the insertion side latching | locking part 30 exceeds the connection part 44, the connection part 44 will return to an original shape, and, thereby, the surface facing the base end side of the plate-shaped part 32 among the latching protrusions 34 is a connection part. It comes to be locked to 44. The inclined surface 34 f and the surface 35 f are insertion contact portions that come into contact with the inward portion of the connecting portion 44 of the receiving side locking portion 40 when the insertion side locking portion 30 is inserted into the receiving side locking portion 40.

In addition, the structure which the hole part penetrated in the front and back in the connection part is formed, and a latching protrusion latches in the said hole part may be sufficient. In this case, the insertion hole portion need not be a through-hole.

The convex portion 50 is formed on at least a part of at least one of the

inclined surfaces

34f and 35f that are the insertion side contact portions and the

inclined surfaces

44f and 45f that are the reception side contact portions.

Here, convex portions 50 are formed on the inclined surface 34f and the surface 35f on the insertion side locking portion 30 side. Further, the inclined surface 44f and the surface 45f on the receiving side locking portion 40 side are formed into smooth surfaces (here, the inclined surface 44f and the surface 45f are flat surfaces) when observed with the naked eye.

The convex part 50 is a convex part intentionally formed by die molding or cutting, etc., and is formed in such a size that it can be recognized by the naked eye. Here, the plurality of convex portions 50 are formed so as to be arranged in a lattice point form on the inclined surface 34f and the surface 35f. The plurality of convex portions 50 may be formed so as to be arranged without regularity. It is not essential that the convex portion 50 is formed on the entire inclined surface 34f and the surface 35f. However, in view of the role of the convex portion 50 described later, the convex portion 50 is formed on the distal end side in the insertion direction, that is, on the distal end side of the inclined surface 34f, of the inclined surface 34f and the surface 35f that are the insertion side contact portions. Preferably it is.

The convex portion 50 is formed in a shape that protrudes while drawing a curved surface that protrudes outward. Here, the convex part 50 is formed in the hemispherical shape. In addition, the convex part 50 may have a shape obtained by dividing the spheroid into halves. Moreover, it is not essential that the convex part 50 is formed in the shape which protrudes, drawing the curved surface which becomes convex outward. In addition, a cylindrical shape, a prism shape, a cone shape, a pyramid shape, a truncated cone shape, a truncated pyramid shape, and the like may be used.

The plurality of convex portions 50 may be formed densely in contact with each other, or may be formed in a state where a gap is left between them.

The height of the convex portion 50 is preferably 0.1 mm to 0.5 mm. This is because if the height dimension is too large, it will be caught by the receiving side locking portion 40. Moreover, if the height dimension is too small, it is difficult for the convex portion 50 to crush fine protrusions on the mating surface.

When inserting the insertion side latching part 30 into the receiving side latching part 40, operation | movement of the said convex part 50 is demonstrated.

FIG. 5 shows an inclined surface 34 f on the insertion side locking portion 30 side and an inclined surface 44 f on the receiving side locking portion 40 side in a state where the insertion side locking portion 30 is being inserted into the receiving side locking portion 40. It is a figure which shows the relationship.

When the insertion side latching portion 30 is inserted into the receiving side latching portion 40, the inclined surface 34f moves relatively while being strongly pressed against the inclined surface 44f. Here, even if the inclined surface 44f (the same applies to the surface 44f) on the receiving-side locking portion 40 side is formed on a smooth surface by design, a fine uneven shape appears on the surface. Similarly, a fine uneven shape also appears on the inclined surface 34f of the insertion side locking portion 30 and the surface of the convex portion 50 formed thereon. These are minute uneven shapes that are difficult to observe with the naked eye and cannot be observed without a microscope. 5 to 8, for convenience of explanation, the uneven shape is exaggerated and drawn greatly.

For this reason, when the convex portion 50 on the inclined surface 34f starts to contact the inclined surface 44f, as shown in FIG. 6, the tip of the fine protrusion 60 on the surface of the convex portion 50 becomes a fine protrusion on the surface of the inclined surface 44f. Contact the tip of 60.

At this time, since the convex portion 50 is formed on the inclined surface 34f, the projection 60 mainly at the tip of the convex portion 50 comes into contact with the projection 60 on the inclined surface 44f side. For this reason, the force for moving the inclined surface 34f relative to the inclined surface 44f while the relative movement is mainly caused by the protrusion 60 at the tip of the convex portion 50 and the tip of the convex portion 50 among the protrusions 60 on the surface of the inclined surface 44f. Concentrates on the contacted part. In other words, the contact area between the insertion-side contact portion and the receiving-side contact portion can be reduced. For this reason, as shown in FIG. 7, the tip of the projection 60 at the tip of the projection 50 and the tip of the projection 60 on the surface of the inclined surface 44f where the tip of the projection 50 contacts are crushed, The tip 60a tends to be a rounded protrusion 60a. For this reason, the surfaces of the inclined surface 34f and the inclined surface 44f are likely to be relatively smooth surfaces.

When the insertion side locking portion 30 is further inserted into the receiving side locking portion 40, there is a region where the inclined surface 44f and the inclined surface 34f come into contact with each other at the portions where the fine protrusions 60 are crushed. As a result, the force required to insert the insertion-side locking portion 30 into the receiving-side locking portion 40 can be reduced as much as possible.

Incidentally, assuming that the convex portion 50 is not formed, as shown in FIG. 8, the surface of the inclined surface 534f conceived of the fine protrusion 560 on the surface of the inclined surface 544f conceived to the inclined surface 44f and the surface of the slanted surface 534f conceived of the inclined surface 34f. Therefore, the force does not collect on the specific protrusion 160 but acts on the protrusions 560 in a distributed manner. For this reason, it is considered that the protrusion 560 is not easily crushed and the initial shape is easily maintained. For this reason, even if the insertion side latching portion is inserted into the receiving side latching portion to some extent, the state where the projections 560 mesh with each other is maintained, and the projections 560 mesh with each other as the insertion side latching portion is inserted. Matching areas will increase. Thereby, it is thought that the force required when inserting the insertion side latching | locking part 30 in the receiving side latching | locking part 40 becomes large.

As described above, according to the present embodiment, the

inclined surfaces

34f and 35f that are the insertion side contact portions of the insertion side locking portion 30, and the inclined surfaces 44f that are the reception side contact portions of the reception side locking portion 40 and Since the convex portion 50 is formed on at least a part of at least one of the surfaces 45f, the inclined surface 34f, the surface 35f, and the inclined surface 44f are inserted when the insertion side locking portion 30 is inserted into the receiving side locking portion 40. And the surface 45f are in contact with each other in a relatively small area. For this reason, the fine protrusions 60 on the surfaces of the

inclined surfaces

34f and 35f and the

inclined surfaces

44f and 45f are crushed and become smoother surfaces. Thereby, after inserting the insertion side latching | locking part 30 to some extent, the force required when inserting the insertion side latching | locking part 30 in the receiving side latching | locking part 40 can be made as small as possible.

Further, when the insertion side locking part 30 is inserted into the receiving side locking part 40, the locking protrusion 34 comes into contact with the connecting part 44 and elastically deforms the connecting part 44. And if the latching protrusion 34 exceeds the connection part 44, the connection part 44 will return to an original shape, and the latching protrusion 34 is the structure which carries out locking prevention to the connection part 44. For this reason, the locking projection 34 is strongly pressed against the connecting portion 44, and the insertion force is increased. In the present embodiment, since the convex portion 50 is formed, the fine protrusions 60 on the surfaces of the inclined surface 34f and the surface 35f and the inclined surface 44f and the surface 45f are crushed at the initial stage of insertion as described above. Becomes a smoother surface. Thereby, if the insertion side latching | locking part 30 is inserted in the receiving side latching | locking part 40 to some extent, the force required when inserting the insertion side latching | locking part 30 in the receiving side latching | locking part 40 can be made as small as possible. .

Here, one of the inclined surface 34f and the surface 35f that are the insertion side contact portions of the insertion side locking portion 30 and the inclined surface 44f and the surface 45f that are the reception side contact portions of the reception side locking portion 40 (here) Then, the convex portion 50 is formed on at least a part of the insertion side contact portion), and the other side (here, the reception side contact portion) is formed on a smooth surface (observed with the naked eye). The contact portion and the locking side contact portion are difficult to mesh with each other. Therefore, the insertion side locking portion 30 can be inserted with the receiving side locking portion 40 as low as possible.

Moreover, since the convex part 50 is formed in the shape which curves so that it may become convex outward, the convex part 50 becomes difficult to get caught in the other party insertion side contact part or a receiving side contact part. For this reason, the insertion side latching | locking part 30 can be inserted more smoothly with respect to the receiving side latching | locking part 40. FIG.

In addition, unlike the insertion side locking part 130 and the receiving side locking part 140 according to the modification shown in FIG. The convex part 150 may be formed in at least one part (in the figure inclined surface 44f) of the inclined surface 44f and the surface 45f which are side contact parts.

Further, convex portions may be formed on both the insertion side locking portion and the receiving side locking portion.

Moreover, like the insertion side latching | locking part 230 which concerns on the modification shown in FIG. 10, the cylindrical surface or the elliptical column was divided into 2 sideways at least to one part of the inclined surface 34f which is an insertion side contact part, and the surface 35f. A convex portion 250 having a shape may be formed. Here, a plurality of convex portions 250 are formed so as to be aligned along the extending direction of the insertion side locking portion 230, and the extending direction of each convex portion 250 is along the extending direction of the insertion side locking portion 230. ing.

Even in this case, as in the above embodiment, the contact area between the insertion side contact portion and the reception side contact portion can be reduced, thereby crushing the fine protrusions and engaging the insertion side locking portion with the reception side engagement. The force at the time of inserting into the stop can be made as small as possible.

The convex portion 250 may be formed at the receiving side contact portion.

Although the present invention has been described in detail as described above, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
