A connector is a relay station for wire harnesses in an automotive circuit. The main function of the wire harness connector buckle is to clamp and fix the wire harness to prevent the wire harness from loosening and shifting.

[0003] The existing assembly process of a wire harness and a connector is realized on an assembly board. By installing positioning parts on the assembly board to position the wire harness wiring, the traditional operation method is to set multiple nails on the wire harness assembly board, and use the nails to position the wire harness connector. When wiring the wire harness, the wire needs to be pulled, and at this time, the nails nailed on the assembly board are prone to loosen or fall off due to the force.

The unqualified connectors flow out, and the short connector at the client installation size cannot be inserted into the equipment device on the accessory, resulting in the equipment being unable to work. Moreover, the nails nailed on the assembly board are prone to loosen and fall off, and it is inconvenient to maintain after loosening. Content of the Utility Model

[0048] Optionally, as Figure 4 shown, the connecting plate member 2 has an L-shaped structure, including a fixing plate 21 and a supporting plate 22 that are perpendicularly connected to each other. The positioning seat 1 is fixed on the fixing plate 21, and bolt holes are provided on the supporting plate 22. The supporting plate 22 is fixed on the assembly plate by bolts. Through the supporting plate 22, a certain spacing is reserved between the fixing plate 21 and the assembly plate, thereby leaving the wire harness connector suspended in the middle of the assembly plate, facilitating the installation of cable ties or adhesive tapes.

[0049] Combined with the above preferred embodiments, the specific working steps of the connector positioning device include: inserting the wire harness connector into the positioning groove 11. The notch on the side wall of the positioning groove 1 can also play a guiding role to facilitate the installation of the connector. Start the cylinders on both sides. The cylinder connecting rods move forward, pushing the calipers on both sides of the positioning groove 11 towards the connector, and using the pressing head to lock the connector in the positioning groove 11, completing the positioning and clamping of the connector. When the wire harness assembly is completed, turn off the cylinders. The cylinder connecting rods move backward, and the calipers on both sides of the positioning groove automatically open under the action of the return spring, and the connector can be taken out of the positioning groove. This positioning tooling has a simple structure, is easy to operate, has high reliability, and has high installation and disassembly efficiency of the connector, which is beneficial to improving the overall rhythm of wire harness assembly.
