A wiring harness is usually composed of multiple strands of wires, sheaths, and connectors. The wires are usually made of copper or copper alloys and have good conductivity and corrosion resistance.

[0003] The existing related technologies often have the following defects: when an external force pulls between the connector and the cable during the use of the wiring harness, the connection between the cable and the connector may be torn off, thereby shortening the service life of the wiring harness.

[0004] Therefore, the utility model provides a long-life wire harness. Utility Model Content

[0007] The effect achieved by the above components is: by setting two spring sheets to squeeze the wire near the connector, the resistance of the wire to the connector when it is pulled by external force is increased, thereby improving the stability of the connection between the wire and the connector.

[0008] Preferably, a plurality of convex strips are evenly and fixedly connected to the surface of the spring piece, and the cross section of the convex strip is triangular.

[0009] The effects achieved by the above components are: by providing the convex strips, the friction between the spring sheet and the wire is further increased, the resistance of the wire when it is pulled is increased, and the stability of the connection between the wire and the connector is improved.

[0010] Preferably, a sliding frame is slidably connected to the side wall of the joint, and two push frames are fixedly connected to the surface of the sliding frame, and the push frames are of an "L"-shaped structure.

[0011] The effect achieved by the above components is that the sliding frame drives the pushing frame to open the space between the two spring sheets.

[0012] Preferably, two connecting plates are fixedly connected to the surface of the sliding frame, and the surfaces of the connecting plates are provided with anti-slip grooves.

[0013] The effects achieved by the above components are as follows: the anti-slip grooves on the connecting plate increase the friction between the hand and the connecting plate, making it easier to push the sliding frame.

[0014] Preferably, a stopper is fixedly connected to the side wall of the joint.

[0015] The effect achieved by the above components is that the setting of the stopper can prevent the sliding frame from slipping off the side wall of the joint.

[0016] Preferably, a connecting pin is fixedly connected to the surface of the stopper, and an end side of the connecting pin is rotatably connected to a supporting block.

[0017] The effect achieved by the above components is: when the sliding frame moves to the side of the support block away from the connecting pin, the support block is rotated to support the support block on the surface of the sliding frame between the sliding frame and the stop block, thereby realizing temporary support work between the spring pieces after being stretched open.

[0024] Reference Figure 1-3 As shown, the utility model provides a technical solution: a long-life wiring harness, comprising a plurality of wires 1, and connectors 2 are fixedly connected to the end sides of the plurality of wires 1.

[0025] The following is a detailed description of its overall specific settings and functions.

[0026] In this embodiment: two spring sheets 3 are fixedly connected to the surface of the connector 2, and a plurality of wires 1 are located between the two spring sheets 3. By setting two spring sheets 3 to squeeze the wires 1 near the connector 2, the resistance of the wires 1 at the connection with the connector 2 when being pulled by an external force is increased, thereby improving the stability of the connection between the wires 1 and the connector 2. A plurality of convex strips 10 are evenly fixedly connected to the surface of the spring sheet 3, and the cross section of the convex strips 10 is triangular. By setting the convex strips 10, the friction between the spring sheet 3 and the wires 1 is further increased, the resistance of the wires 1 when being pulled is increased, and the stability of the connection between the wires 1 and the connector 2 is improved.

[0027] Specifically, the side wall of the joint 2 is slidably connected with a sliding frame 6, and the surface of the sliding frame 6 is fixedly connected with two push frames 4, and the push frames 4 are "L"-shaped structures. The sliding frame 6 drives the push frames 4 to open the two spring sheets 3. The surface of the sliding frame 6 is fixedly connected with two connecting plates 9, and the surface of the connecting plates 9 is provided with anti-slip grooves. The anti-slip grooves on the connecting plates 9 increase the friction between the hand and the connecting plates 9, and facilitate the pushing work of the sliding frame 6.

[0028] The side wall of the joint 2 is fixedly connected with a stopper 5. The setting of the stopper 5 can prevent the sliding frame 6 from slipping off the side wall of the joint 2. The surface of the stopper 5 is fixedly connected with a connecting pin 7, and the end side of the connecting pin 7 is rotatably connected with a supporting block 8. When the sliding frame 6 moves to the side where the supporting block 8 is away from the connecting pin 7, the supporting block 8 is rotated to support the surface of the sliding frame 6 between the sliding frame 6 and the stopper 5, so as to realize temporary support work between the spring pieces 3 after being stretched out.

[0029] Working principle: by setting two spring pieces 3 to squeeze the wire 1 near the connector 2, the resistance of the wire 1 to the connector 2 when it is pulled by an external force is increased, thereby improving the stability of the connection between the wire 1 and the connector 2. By setting the convex strip 10, the friction between the spring piece 3 and the wire 1 is further increased, the resistance of the wire 1 when it is pulled is increased, and the stability of the connection between the wire 1 and the connector 2 is improved. When it is necessary to replace a single wire 1, the sliding frame 6 on the connector 2 can be pushed. The anti-slip pattern on the connecting plate 9 increases the friction between the hand and the connecting plate 9, which facilitates the pushing work of the sliding frame 6. The frame 6 will drive the push frame 4 to stretch the two spring sheets 3. When the sliding frame 6 moves to the side of the support block 8 away from the connecting pin 7, the support block 8 is rotated to support the support block 8 on the surface of the sliding frame 6 between the sliding frame 6 and the stop block 5, so as to realize temporary support work between the spring sheets 3 after stretching, thereby facilitating the replacement of the connection position between the single wire 1 and the connector 2. The setting of the stop block 5 can prevent the sliding frame 6 from slipping off the side wall of the connector 2. By setting the above structure, the flexible reinforcement work of the connection between the connector 2 and the wire 1 is facilitated, and the stability of the connection position of the wire 1 and the connector 2 is improved to a certain extent, thereby extending the service life of the wiring harness.
