[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a protector for protecting a wire harness (automotive electric wire), and more particularly to a protector applied to the branch portion of a wire harness having a branch portion.

[0002]

[Prior art]

 Conventionally, it has been applied to a flexible tubular body such as a corrugated tube or a branching portion of a wire harness that is bundled by tape winding, and is described as a protector for protecting the wire harness, for example, in Japanese Utility Model Publication No. 2-60419. It is known that

That is, as shown in FIG. 4, the protector 1 has a gutter-shaped main body 2 for accommodating a wire harness to be described later, and a lid 6 connected to the main body 2 via a hinge edge 5. A window for the branch line 3 of the wire harness 4 to be drawn out to the side wall 2a on one side forming the main body 2 while the lid 6 can close the opening portion of the main body 2. It is constructed by opening Department 9. Further, an elastic holding piece 10 for binding and holding the branch line 3 with the tape T is formed in a cantilever shape along the side wall 2a of the main body 2 in the window portion 9, and the elastic holding piece is formed. A free end side 10 for pulling out the branch line 3 is provided so as to be flexibly deformed outward.

When the protector having such a configuration is applied to the branching portion, the protector 1 stores the wire harness 4 in the main body 2, further bundles the branch wire 3 with the elastic holding piece 10, and then closes the lid. It can be attached to the body etc. At this time, the branch line 3 has a length with an appropriate allowance added to the length required for actual connection in order to facilitate connection work with an electrical device to be connected, for example, the main body 2 Have been drawn from. However, since such an extra length of the branch line 3 comes into contact with the body or the like after connection with an electric device and becomes a source of noise, for example, the branch line 3 is stretched after connection. Need to be established. Therefore, in the protector 1 as described above, as shown in FIGS. 6 and 7, the branch line 3 is appropriately obtained by using the bending of the elastic holding piece 10 to have a length (S1 dimension) required for actual connection. It was provided so as to be able to be drawn out for a length in which a loose portion (S2 size) was added, and after connection, the loose portion was absorbed by the return of the elastic holding piece 10 so as to be tense.

[0005]

[Problems to be solved by the device]

 However, in the conventional protector having the above-mentioned structure, the bending of the elastic holding piece is used to obtain the tension of the branch line, so that the strength of the elastic holding piece is weakened and the holding piece may be damaged. Further, when the elastic holding piece bends, it bends in a bow shape and interferes with an obstacle in the vicinity, so that it may not be possible to obtain sufficient bending deformation. Furthermore, the tension of the branch line due to the flexure of the elastic holding piece was not able to cope when the allowable range was narrow and a large change in the drawing length was required.

The present invention has been made in view of the above circumstances, and a wire harness can be housed and protected, a branch line can be drawn out according to a required length, and a traverse such as breakage does not occur. It is intended to provide a protector for a harness.

[0007]

[Means for Solving the Problems]

 That is, the above object of the present invention is to provide a protector for protecting a wire harness, the main body being provided in a hollow shape by closing the lid, and the main body which is transparently provided along the longitudinal direction of the main body and accommodated in the main body. Window for drawing out the branch line of the wire harness, a slide cover slidably mounted on the main body so as to partially close the window, and a locking means for regulating the position of the slide cover at a predetermined position. And a wire harness protector.

[0008]

[Action]

 By sliding the slide cover to block the window formed in the long hole stepwise and partially to change the size of the window opening surface, and pressing the branch line at the end of the slide cover. The length of the branch line that is inserted through the window and drawn out from the protector can be made variable. Further, in this protector, the length of the branch line drawn out is adjusted by the slide amount of the slide cover, so that the window can be opened widely and the sliding area can be set long so that the branch line can be drawn out long. ..

 Hereinafter, an embodiment of a protector for a wire harness according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of a protector according to an embodiment of the present invention when it is attached to a wire harness, and FIG. 2 is a perspective view illustrating how the protector is attached to a wire harness. .. Note that, in FIG. 2, a slide cover, which will be described later, is shown in a state of being detached from the main body and turned over for easy understanding.

In the figure, the protector 20 is provided with a main body 21 having a U-shaped cross section and capable of accommodating a wire harness 40, a side wall 22 of the main body 21 and a hinge portion 23, and the protector 20 is continuously connected to the main body 21. A lid portion 24 formed so as to cover the opening portion of the main body 21; a window portion 26 formed in a side wall 25 facing the side wall 22 and provided as a long hole along the longitudinal direction of the main body 21; A pair of rails 27 extending along the longitudinal direction of the main body 21 and fixed to the outer surface of the side wall so as to sandwich the window portion 26, and a slide cover 28 fitted to the rails 27 and slidably provided. It is composed of and.

The main body 21 is formed in a hollow shape with the lid 24 closed. The rail 27 and the slide cover 28 will be described in more detail. The rail 27 is formed to have an inverted L-shaped cross section, and is projected. It is arranged so that. On the other hand, both ends of the flat plate surface of the slide cover 28 are slightly bent in a U shape in the same direction, and the top portions 27a of the rails 27 are provided so that they can be fitted therein.

In addition, the protector 20 includes a locking step 30 for fixing the cover 28 stepwise at a specific position in a state where the slide cover 28 is fitted to the rail 27 and restricting the position, and the main body. A space 35 (see FIG. 3) is provided upright along the window 26 in the inside of 21 and is provided in the same length as the longitudinal direction of the window 26 so as to have a narrow space with the cover 28. And a back wall 29 to be formed.

More specifically, the locking means 30 is composed of a locking projection 31 and a plurality of locking holes 32 with which the projection 31 engages, and the locking projection 31 includes the slide cover. On the back surface of 28, it is provided so as to project toward one end thereof. On the other hand, a plurality of the locking holes 32 are provided between the rails 27 at a predetermined interval on the side wall 25 corresponding to the rear side of the wire harness 40 from the window 26.

In addition, the tip of the lid portion 24, which is rotated via the hinge portion 23, on the free end side is slightly bent, and is superposed on the side wall 25 of the main body 21 when the lid is closed. The short wall 24a is formed with a pair of locking claws 33, which are spaced apart from each other and project from the tip edge 24b of the short wall 24a. The locking claws 33 are for locking the lid part 24 in the closed state, and the receiving parts 34 into which the locking claws 33 are detachably fitted are attached to the outer surfaces of the corresponding side walls of the main body 21 side. Is provided.

Next, with reference to FIG. 3 as well, a procedure for mounting the protector 20 having such a configuration on the branch portion of the Wiener harness 40 will be described. Note that FIG. 3 is a cross-sectional view taken along the line AA in FIG. The protector 20 stores the wire harness 40 in the main body 21 with the lid 24 opened. At this time, the branch line 42 branched from the main line 41 of the wire harness 40 is disposed in the narrow space 35 formed by the back wall 29 and the slide cover 28 attached to the main body 21 in the subsequent work. Moreover, after guiding along the back wall 29, the window portion 26 is penetrated and pulled out to the outside. A connector 43 (see FIGS. 1 and 2) connected to an electric device is attached to the tip of the branch line 42.

Next, the protector 20 is attached to the body using an appropriate fixing means, and then the connector 43 is connected to an electric device with the slide cover 28 fitted to the rail 27. After connecting the connector 43 to an electric device, the slide cover 28 is slid. In this sliding operation, the edge of the slide cover 28 is brought into contact with the branch line 42, and further, in order to improve the workability of connection with an electric device, the length of the allowance provided in advance in the branch line 42 is increased. This is achieved by pressing the branch line 42 so as to absorb the force and engaging the locking projection 31 of the slide cover 28 with one of the locking holes 32 of the main body 21 to position the cover 28 at a specific position. It is about regulating and fixing. By such a sliding operation, the branch line 42 is housed in the narrow space 35, and is also tensioned and wired in a desired state. At the time when the branch line 42 is stretched, finally, the lid portion 24 is rotated in the direction of the arrow R to be closed, and the locking claw 33 and the receiving portion 34 are engaged with each other to close the lid portion 24. The mounting work is completed by locking the part 24 in the closed state.

In the mounting process, when it is desired to pull out the branch line 42 for a long time, the slide cover 28 is slid so that the opening surface of the window portion 26 formed in the long hole is further opened. Thereby, the branch line 42 drawn out from the protector 20 is substantially extended and can be drawn out for a long time. By mounting the protector of the present invention in such a procedure, the slide cover can be stretched by absorbing a length corresponding to a clearance provided in advance in the branch line by sliding the slide cover.

By applying the protector of the present invention to all branching parts of a series of wire harnesses and provisionally setting in advance the length of the branching line drawn out from the protector to the minimum, It is possible to prevent troubles caused by entanglement of branch lines during shipment or wiring of the harness, and to improve both shipping workability and wiring workability.

[0019]

[Effect of the device]

 As described above, according to the protector of the present invention, the branch line of the wire harness can be stored, and the extension length of the branch line can be adjusted by the slide amount of the slide cover. At this time, since the slide cover does not deform like the elastic holding piece having the conventional structure, troubles such as breakage do not occur. In addition, the amount of extension of the branch line can be adjusted simply by sliding the slide cover, and the work efficiency can be improved and the branch line can be stretched. Further, the slide cover can set the slide amount in a wider allowable range as compared with the case of the elastic holding piece, and therefore has a high versatility in flexibly responding to a large change in the withdrawal amount. Furthermore, the length of the branch line can be adjusted by the slide cover without causing interference with other members close to the protector.
