[0002] The wiring harness (also called cable harness) in new energy vehicles is composed of multiple wires and connectors, which are used to transmit power and signals. The plastic shell of the wiring harness usually refers to the insulating protective material outside the wiring harness, which is used to protect the wires inside the wiring harness from the influence of the external environment, such as moisture, dust, chemicals and mechanical damage. In addition, when the wiring harness is used to connect electrical equipment, in order to prevent the wiring harness from moving or falling off during operation, the wiring harness needs to be fixed. Traditionally, the wiring harness is fixed by fixing accessories installed on the wiring harness plastic shell to firmly fix the wiring harness plastic shell on the equipment or vehicle body.

[0030] During operation, when installing the accessories for fixing the existing wiring harness plastic shell, it is necessary to first insert the accessories into the mounting hole of the wiring harness plastic shell, and then place the wiring harness plastic shell on the workbench 1, and push the accessories into the mounting hole of the wiring harness plastic shell by using a hydraulic assembler. However, because the accessories are manually inserted into the mounting hole of the wiring harness plastic shell, if deviation occurs during the manual operation, that is, when the accessories inserted into the mounting hole of the wiring harness plastic shell are tilted, when the tilted accessories are pushed by the hydraulic assembler, the tilted accessories will generate uneven pressure on the inner wall of the mounting hole of the wiring harness plastic shell, causing the plastic shell to deform, crack or break, so that the accessories and the wiring harness plastic shell cannot be firmly connected;

[0031] In this regard, the utility model can cooperate with the pressure block 111 through the support plate 14, so that the support plate 14 can support the accessories, so that the accessories are clamped between the support plate 14 and the pressure block 111 and are in a vertical state, so that there is no need to manually insert the accessories into the mounting hole of the wiring harness plastic shell, avoiding errors caused by human factors, so as to prevent the accessories inserted into the mounting hole of the wiring harness plastic shell from tilting, and thus avoid the accessories pushed by the hydraulic push rod 112 from exerting uneven pressure on the inner wall of the mounting hole of the wiring harness plastic shell, avoiding deformation, cracks or damage of the plastic shell, not only reducing the loss of the plastic shell and reducing the production cost, but also ensuring the normal and stable connection between the accessories and the wiring harness plastic shell, so that the connection effect and connection efficiency between the accessories and the wiring harness plastic shell are improved;

[0032] In the initial state, a flange is provided on the surface of the fixing accessory. The user first rotates the worm 152 so that the worm 152 can drive the worm wheel 151 meshing with it to rotate, so that the worm wheel 151 spirally descends relative to the lead screw 15, so that the worm wheel 151 pushes the clamping plate 142 to descend, so that the clamping plate 142 moves away from the straight plate 141, and then controls the electromagnetic ring 133 to be energized so that the electromagnetic ring 133 can generate the same magnetic pole as the magnet 16, so that the magnet 16 is pushed by the magnetic repulsion and stretches the support spring 132 to move towards the direction of the pressure block 111, until the straight plate 141 contacts the pressure block 111, and is now located below the pressure block 111, and then the accessory is placed between the two clamping plates 142 so that the two The clamping plate 142 supports the accessory through the flange of the accessory, and finally rotates the two worms 152 in the opposite direction, so that the worm 152 drives the worm wheel 151 to rotate in the opposite direction, so that the worm wheel 151 spirals up relative to the lead screw 15, so that the worm wheel 151 can push the clamping plate 142 to rise, so that the clamping plate 142 pushes the accessory to rise and enter the groove 113 at the lower end of the pressing block 111, until the upper end surface of the flange of the accessory contacts the lower end surface of the pressing block 111, at this time, the pressing block 111 and the clamping plate 142 clamp the flange; then place the wiring harness plastic shell on the base 2 of the workbench 1, and the setting of the base 2 is to facilitate the installation of the strip plate 22, that is, by installing the two strip plates 22 in the clamping groove 21, and rotating The tightening rod 23 in the threaded groove 221 of the movable strip plate 22 allows the tightening rod 23 to penetrate into the clamping groove 21, so that the lower end of the tightening rod 23 contacts and tightens with the bottom of the clamping groove 21, thereby fixing the strip plate 22 and the base 2. At this time, the two strip plates 22 can limit the wiring harness plastic shell just below the pressing block 111, so that when the wiring harness plastic shell is placed later, it only needs to be inserted between the two strip plates 22 to ensure that the center of the mounting hole of the wiring harness plastic shell and the center of the accessory are in the same plane; and through the setting of the blocking plate 25, after the strip plate 22 is fixed and installed, the user can rotate the screw 26 so that the screw 26 can be spirally rotated relative to the mounting plate 24, so that the screw 26 The blocking plate 25 is rotated in the direction away from the mounting plate 24; since the blocking plate 25 is located between the two strip plates 22, the blocking plate 25 will be limited by the strip plates 22; when the screw rod 26 is spirally rotated, the screw rod 26 rotates relative to the blocking plate 25, so that the screw rod 26 pushes the blocking plate 25 to move away from the mounting plate 24 until the blocking plate 25 contacts the wiring harness plastic shell, so that the wiring harness plastic shell is pushed by the blocking plate 25 and drives the mounting holes on the surface to move synchronously until the mounting holes are located directly below the accessories, thereby facilitating the subsequent positioning of the wiring harness plastic shell, thereby greatly shortening the assembly time of the wiring harness plastic shell and the accessories, and improving the assembly rate of the accessories and the wiring harness plastic shell; so that the practicality of the utility model is improved;

[0033] When the wiring harness plastic shell is placed, the two starters 12 are pressed synchronously to control the hydraulic push rod 112 to descend, so that the hydraulic push rod 112 can push the pressing block 111 to descend, so that the pressing block 111 drives the supporting plate 14 to descend through the L-shaped plate 13, so that the pressing block 111 drives the accessories clamped by it and the clamping plate 142 to descend until the accessories contact the wiring harness plastic shell, so that the pressing block 111 squeezes the accessories and inserts them into the mounting hole of the wiring harness plastic shell under the push of the hydraulic push rod 112, and as the hydraulic push rod 112 continues to push, the pressing block 111 squeezes the accessories and continuously inserts them into the mounting hole. In the mounting hole, before the clamping plate 142 contacts the wiring harness plastic shell, the electromagnetic ring 133 is controlled to pass a reverse current, so that the electromagnetic ring 133 can generate a magnetic pole opposite to the magnet 16, so that the magnet 16 is subjected to the combined effect of the magnetic adsorption force and the restoring force of the support spring 132, so that the magnet 16 drives the clamping plate 142 to move away from the pressing block 111, so that the clamping plate 142 is away from the accessory, so that the clamping plate 142 is no longer located under the flange of the accessory, that is, the accessory will not be blocked by the clamping plate 142, so as to ensure that the accessory squeezed by the pressing block 111 can be embedded in the wiring harness plastic shell. Then, the hydraulic push rod 112 is controlled to rise, so that the hydraulic push rod 112 pulls the pressing block 111 to rise. At this time, the accessories embedded in the wiring harness plastic shell are exposed from the groove 113 and away from the pressing block 111. Then, the electromagnetic ring 133 is controlled again to generate the same magnetic pole as the magnet 16, and then a new accessory is inserted into the groove 113, so that the flange of the accessory contacts the lower end surface of the pressing block 111, and the accessory is pushed to slide along the groove 113 toward the direction close to the clamping plate 142, so that the flange of the accessory is inserted between the clamping plate 142 and the pressing block 111, thereby starting a new round of wiring harness. Assembly of the plastic shell and accessories; and the setting of the bellows 17 enables the bellows 17 to protect the support spring 132, to prevent impurities in the assembly workshop or debris generated by the extrusion of accessories from splashing onto the support spring 132, to prevent the support spring 132 from being blocked by debris or impurities and unable to effectively shrink, thereby ensuring that the utility model can be used normally and stably, and further improving the practical application effect of the utility model; by setting two starters 12, the safety of use of the equipment is improved, and the practicality of the utility model is improved.
