Description

  The present invention relates to a clip for holding a cable such as an electric wire and holding it at a wiring location, and particularly for a cable in which the cross-sectional shape of the cable is elliptical and directivity is required in the direction of the wire diameter in the held state. Regarding clips.

In order to fasten a cable having a circular cross-sectional shape at a predetermined location, such as a normal electric wire (single wire) or a wire harness, for example, a clip as disclosed in Patent Document 1 is used. This clip includes a belt for bundling a cable (for example, a wire harness), and a locking leg that can be inserted into a mounting hole opened in a wiring location. The belt can be wound around the outer periphery of the cable and tightened, whereby the cable is gripped on the clip side. In this state, the cable is fastened to the wiring location through the clip by inserting the locking leg into the mounting hole.
Japanese Patent Laid-Open No. 11-308739

  If the cable has an elliptical cross-section and the direction of the wire diameter is required when the cable is held by a clip, the cable must be held by hand or jig while the cable is tightened by the belt. . In addition, when the cable is tilted in the direction of the cable diameter when the belt is tightened, the gripping force with respect to the cable is insufficient, causing the cable to move in the length direction.

  The present invention is intended to solve such problems, and its purpose is to keep the gripping force on the cable at an appropriate value and prevent the cable from shifting in the length direction, and the direction of the wire diameter direction. In order to maintain the characteristics, it is unnecessary to hold the cable with a hand or a jig.

The present invention is for achieving the above object, and is configured as follows.
A cable clip that has an elliptical cross-section and requires directivity in the direction of the wire diameter of the cable in the gripped state. A clamp member that is connected to the main body by a hinge and that can be gripped with a cable sandwiched between the main body, an insertion portion provided on the clamp member, and the insertion portion on the socket. By inserting, the locking means that can lock the clamp member in the state of gripping the cable to the socket side, and before the locking means is locked, the wire diameter direction of the cable is properly maintained. Temporary locking means is provided that can temporarily fix the clamp member to the socket side in the slack state.
The lock means is constituted by lock claws provided respectively in the socket and the insertion part of the clamp member, and the temporary lock means is constituted by temporary lock claws provided in the socket and the insertion part of the clamp member. Then, by inserting the insertion portion into the socket, the two temporary lock claws are first locked with each other, and by further inserting the insertion portion, both the temporary lock claws are unlocked and the both lock claws are locked with each other. Is set to Moreover, the lock claw and temporary lock claw in the socket are formed on inner walls adjacent to each other.

In this configuration, if the clamp member can be temporarily fixed to the socket side by the temporary locking means, the direction of the wire diameter in the cable is nothing but the proper wire diameter. It can be locked in the direction. Thereby, the gripping force with respect to the cable after locking is maintained at an appropriate value, and the cable is prevented from moving in the length direction. In addition, after the clamp member is temporarily fixed by the temporary lock means, the work of holding the cable with a hand or a jig in order to maintain the directionality becomes unnecessary, so that workability is improved.
Moreover, about the inside of a socket, it becomes possible to shape | mold a lock nail | claw and a temporary lock nail | claw, without using a slide type | mold for a shaping | molding die.

The best mode for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 is a front view showing a cable clip. FIG. 2 is a plan view of FIG. FIG. 3 is a perspective view showing a cable clip. FIG. 4 is an enlarged cross-sectional view in the direction of arrow AA in FIG.

  The clips shown in these drawings are integrally molded products made of resin. The clip is used mainly when wiring an electric wire 40 (cable) for energizing an ignition device for an airbag inflator in a vehicle along a cushion spring (S spring) inside the seat. Therefore, the clip is roughly divided into a main body 10 for gripping the electric wire 40 and a mounting block 30 for fastening the main body 10 to the cushion spring material. As shown in FIGS. 5 to 9 described later, the electric wire 40 has a substantially elliptical cross-sectional shape, and directionality is required in the direction of the wire diameter when gripped by the clip body 10. It is done.

  The clip main body 10 includes a groove-shaped receiving recess 11 into which a part of the outer periphery of the electric wire 40 can be fitted. The receiving recess 11 is set to a shape that allows the electric wire 40 to be fitted only in the direction along the major axis (FIG. 1), thereby restricting the direction of the wire diameter of the electric wire 40. . The main body 10 is provided with a socket 13 having a rectangular hollow portion penetrating in the vertical direction of the drawing. In the socket 13, a lock claw 14 is formed on the inner wall on the main body 10 side (FIG. 4). Similarly, in the socket 13, a temporary lock claw 16 is formed on the inner wall adjacent to the inner wall having the lock claw 14. The temporary lock claw 16 is formed by stopping one end of the groove 15 formed on the inner wall of the temporary lock claw 16 without opening it to the end of the socket 13. The lock claw 14 and the temporary lock claw 16 are considered so that they can be molded without using a slide mold as a mold.

  The clip body 10 is provided with a clamp member 20 on the opposite side of the socket 13. The clamp member 20 and the main body 10 are coupled by a thin hinge 27 that can be elastically deformed. The clamp member 20 includes a groove-shaped recess 21 that can receive a part of the outer periphery of the electric wire 40. The recess 21 receives an outer periphery of a portion exposed from the receiving recess 11 in the electric wire 40 fitted in the receiving recess 11 of the main body 10. Further, an insertion portion 23 is provided at the distal end portion of the clamp member 20 so as to protrude on the same side as the side where the concave portion 21 is provided. A lock claw 24 and a temporary lock claw 26 are provided at the end of the insertion portion 23. The lock claw 24 and the temporary lock claw 26 can be individually locked to the lock claw 14 and the temporary lock claw 16 on the inner wall of the socket 13 when the insertion portion 23 is inserted into the socket 13.

  The clip mounting block 30 is formed integrally with the outer wall on one side of the socket 13 of the main body 10. The mounting block 30 includes a groove-shaped receiving recess 31 into which a seat cushion spring material can be fitted. In the clip in the present embodiment, the receiving recess 31 of the block 30 and the receiving recess 11 of the main body 10 are located on the opposite sides with respect to the top and bottom. The mounting block 30 is provided with sockets 32 and pressing members 36 on both sides of the receiving recess 31. The pressing member 36 and the block 30 are coupled by a thin hinge 37 that can be elastically deformed. A locking claw 33 is provided inside the socket 32, and a locking claw 38 that can be locked with the locking claw 33 is provided at the tip of the pressing member 36.

Next, an operation for locking the electric wire 40 (cable) in the state where it is held on the main body 10 side of the clamp will be described.
FIG. 5 is a perspective view showing a clip in a temporarily locked state before locking. FIG. 6 is a perspective view showing a clip in a locked state. FIG. 7 is a front view showing a part of the clip in the temporarily locked state. 8 is a cross-sectional view in the direction of arrow BB in FIG. FIG. 9 is a sectional view showing a part of the clip in the locked state.

  When working, first, the electric wire 40 is fitted into the receiving recess 11 of the main body 10 in the direction along the major axis. Next, as shown in FIG. 5, the clamp member 20 is bent at the hinge 27 with respect to the main body 10, and the insertion portion 23 is inserted into the socket 13. Thereby, the temporary lock claw 26 of the insertion part 23 is first latched by the temporary lock claw 16 in the socket 13 (FIGS. 7 and 8). As a result, the clamp member 20 is temporarily fixed to the socket 13 side. However, if the direction of the wire diameter of the electric wire 40 fitted in the receiving recess 11 is inappropriate, the clamp member 20 cannot interfere with the electric wire 40 and bend sufficiently, and the temporary lock claws 16 and 26 are It cannot be locked.

  Further, by inserting the insertion portion 23 into the socket 13, the temporary lock claw 26 of the insertion portion 23 moves in the groove 15 in the socket 13 and moves away from the temporary lock claw 16, and this time the lock claw 24 of the insertion portion 23. Engages with the locking claw 14 in the socket 13 (FIG. 9). As a result, the clamp member 20 is locked to the socket 13 side in a state where the electric wire 40 is gripped by the receiving recess 11 of the main body 10 and the recess 21 of the clamp member 20. As described above, the clamp member 20 can be changed from the temporarily fixed state to the locked state while the wire diameter direction of the electric wire 40 is maintained in an appropriate direction, so that the electric wire 40 before locking is held by a hand or a jig. There is no need for trouble. And the holding | grip force with respect to the electric wire 40 after a lock | rock is kept appropriate, and the load with respect to the shift | offset | difference movement to the length direction of the electric wire 40 is fully ensured.

  The temporary lock claws 16 and 26 correspond to the “temporary lock means” of the present invention, and the both lock claws 14 and 24 correspond to the “lock means” of the present invention.

  In order to hold the clamp to the cushion spring material of the seat, the spring material is fitted into the receiving recess 31 of the mounting block 30, the holding member 36 is bent at the hinge 37, and the locking claw 38 is inserted into the socket 32. As a result, the locking claws 33 and 38 are locked and the pressing member 36 is locked to the socket 32. As a result, the electric wire 40 is wired along the cushion spring material of the seat through the clamp.
