TECHNICAL FIELD OF THE INVENTION
The present invention relates to a wire locking mechanism for locking a wire.
[0002]
[Prior art]
As a wire harness holder, for example, there is a wire harness held by a holder in a state where the wire harness is housed in a substantially cylindrical corrugated tube (for example, see Patent Document 1).
[0003]
In this wire harness holder, a plurality of valleys are formed on the outer periphery of the corrugated tube, and the plurality of valleys are arranged at equal intervals in the axial direction of the corrugated tube, and each valley is formed around the corrugated tube. It is arranged in the whole direction. Thus, the corrugated tube has a bellows shape, and the corrugated tube reduces damage to the wire harness from other components.
[0004]
The holding tool has a substantially cylindrical shape, and the wire harness is held via the corrugated tube when the corrugated tube is inserted into the holding tool. A substantially annular plate-shaped rib is provided in the holder, and the rib is inserted into a valley of the corrugated tube, thereby restricting the movement of the corrugated tube relative to the holder in the axial direction.
[0005]
A biting projection is provided in the holder, and the biting projection bites into the outer periphery of the corrugated tube, so that the rotation of the corrugated tube with respect to the holder is restricted.
[0006]
However, in such a wire harness holder, the corrugated tube may have a variation in shape (tolerance), or the number of wire harnesses (cross-sectional area or stored density) accommodated in the corrugated tube may cause the corrugated tube to have an adverse effect. When the force changes, the biting force of the biting projection on the outer periphery of the corrugated tube may change.
[0007]
For this reason, it is preferable that the rotation of the corrugated tube relative to the holder can be reliably controlled even when the corrugated tube has a variation in shape or when the reaction force of the corrugated tube changes.

Further, the engagement of the distal end of the rigid claw 34 with the distal end of the elastic claw 40 is released, and the rotating portion 30 is rotated with respect to the main body 28 so that the insertion hole 24 can be opened. Thereby, insertion of the corrugated tube 12 into the insertion hole 24 and detachment of the corrugated tube 12 from the insertion hole 24 are enabled.
[0030]
As shown in FIG. 2, when the insertion hole 24 is opened to the maximum extent (the rigid claw 34 of the rotation unit 30 is maximally separated from the mounting cylinder 36), the rotation unit 30 moves relative to the main body 28. When rotated, as shown in FIG. 5A, the hinge portion 32 is extended in a substantially flat shape and does not protrude into the insertion hole 24. Further, when the rotating portion 30 is rotated with respect to the main body portion 28 with the insertion hole 24 being substantially half-opened, as shown in FIG. 5 (B), the hinge portion 32 has a curved plate shape (bent plate). And may protrude slightly into the insertion hole 24. As shown in FIG. 1, when the rotating portion 30 is rotated with respect to the main body portion 28 with the insertion hole 24 closed, as shown in FIG. It is bent into a U-shaped plate (or a substantially V-shaped plate in cross section) and greatly protrudes into the insertion hole 24.
[0031]
As shown in FIGS. 1 to 4, a mounting hole 42 is formed in the side wall of the mounting cylinder 36 on the side opposite to the insertion hole 24, and a mounting claw 44 is provided in the mounting hole 42. The base end of the mounting claw 44 is integrated with the periphery of the mounting hole 42, and the mounting claw 44 is provided with a projection 46 protruding inside the mounting cylinder 36.

[0032]
In the mounting cylinder 36, quadrangular pillar-shaped guide columns 48 are provided on both sides of the mounting hole 42 on the side wall on the side opposite to the insertion hole 24, and each guide column 48 extends to the other end of the mounting cylinder 36.
[0033]
As shown in FIG. 6, a flat fixing plate 50 is inserted into the mounting cylinder 36 between the pair of guide columns 48 from the other end. When the fixing plate 50 is inserted into the mounting cylinder 36, the fixing plate 50 is guided by the pair of guide columns 48, and the projections 46 are pressed by the fixing plate 50 to elastically deform the mounting claws 44. Is done. The fixing plate 50 is fixed to the fixing member 52, and a fixing hole (not shown) is formed in the fixing plate 50, and the projection 46 of the mounting claw 44 is inserted into the fixing hole. Thus, the corrugated clamp 22 is fixed to the fixing member 52.
[0034]
Next, the operation of the present embodiment will be described.
[0035]
In the wire harness holding mechanism 10 having the above-described configuration, a plurality of wire harnesses 14 are accommodated in a substantially cylindrical corrugated tube 12.
[0036]
Further, in the corrugated clamp 22, after the engagement of the tip of the elastic claw 40 with the tip of the rigid claw 34 is released and the insertion hole 24 is opened, after the corrugated tube 12 is inserted into the insertion hole 24, the rotating portion The corrugated tube 12 is inserted through the closed insertion hole 24 by rotating the pivot 30 about the hinge 32 with respect to the main body 28 and engaging the tip of the elastic claw 40 with the tip of the rigid claw 34. . Thereby, the plurality of wire harnesses 14 are held by the corrugated clamp 22 via the corrugated tube 12.
[0037]
The fixing plate 50 fixed to the fixing member 52 is inserted between the pair of guide columns 48 in the mounting cylinder 36 of the corrugated clamp 22, and the fixing hole of the fixing plate 50 is inserted into the protrusion 46 of the mounting claw 44. As a result, the corrugated clamp 22 is fixed to the fixing member 52 via the fixing plate 50.
[0038]
Here, the hinge portion 32 provided on the corrugated clamp 22 is hooked on the slit 20 provided in advance on the corrugated tube 12, so that the rotation of the corrugated tube 12 relative to the corrugated clamp 22 in the circumferential direction is regulated. For this reason, when the shape variation (tolerance) occurs in the corrugated tube 12, or when the reaction force of the corrugated tube 12 changes depending on the number (the cross-sectional area or the stored density) of the wire harnesses 14 housed in the corrugated tube 12. However, the rotation of the corrugated tube 12 in the circumferential direction with respect to the corrugated clamp 22 can be reliably restricted.
[0039]
Further, in the corrugated clamp 22, the rotating portion 30 is rotated about the hinge portion 32 with respect to the main body portion 28 to close the insertion hole 24, so that the hinge portion 32 projects into the insertion hole 24, The hinge portion 32 can be hooked on the slit 20 of the corrugated tube 12. On the other hand, when the rotation portion 30 is rotated about the hinge portion 32 with respect to the main body portion 28 and the insertion hole 24 is opened, it is possible to prevent or suppress the hinge portion 32 from protruding into the insertion hole 24. . For this reason, when inserting the corrugated tube 12 into the opened insertion hole 24, it is possible to prevent or suppress the hinge portion 32 from obstructing the insertion of the corrugated tube 12 into the insertion hole 24, and to insert the corrugated tube 12 into the inserted hole 24. Can be easily inserted.
[0040]
Further, the hinge portion 32 connects the rotating portion 30 and the main body portion 28 to allow the rotating portion 30 to rotate with respect to the main body portion 28, and serves as a corrugated tube that projects into the insertion hole 24 and is provided for the corrugated clamp 22. Since it has two roles, that is, the role of regulating the rotation of the twelfth, the number of parts can be reduced.
[0041]
Further, by inserting the regulating plate 26 of the corrugated clamp 22 into the valley 18 of the corrugated tube 12, the axial movement of the corrugated tube 12 with respect to the corrugated clamp 22 is regulated. Therefore, the circumferential rotation and axial movement of the corrugated tube 12 with respect to the corrugated clamp 22 are regulated, and the movement of the corrugated tube 12 with respect to the corrugated clamp 22 can be regulated in all directions.
[0042]
In this embodiment, the hinge portion 32 (hook portion) is provided in the corrugated clamp 22 (insertion member), and the slit 20 (hooked portion) is provided in the corrugate tube 12 (housing member). A configuration in which a hook portion is provided on the housing member and a hooked portion is provided on the insertion member may be employed.
[0043]
Further, in the present embodiment, the accommodating member is configured to be the corrugated tube 12, but the accommodating member may be configured to omit the corrugated tube as the covering member of the wire harness (wiring).
[0044]
【The invention's effect】

[0045]
In the wiring locking mechanism according to claim 2, the hooking portion can be hooked on the hooked portion by closing the insertion hole by the rotation of the turning portion with respect to the main body portion, and thus the hooking portion of the insertion member or the hooked portion. Can be prevented or suppressed from hindering insertion of the housing member into the opened insertion hole, and the housing member can be easily inserted into the insertion hole.
[0046]
In the wiring locking mechanism according to the third aspect, since the regulating means regulates the movement of the housing member relative to the insertion member in the axial direction, the movement of the housing member relative to the insertion member can be restricted in all directions.
