Description

Technical Field

[0002] The automotive wiring harness is the network backbone of the vehicle's electrical circuits. Without it, there would be no automotive circuits. A wiring harness is a component that connects wires and cables to contacts (connectors) punched from copper, then plastic-bonded with insulation and a metal housing to form a bundled circuit.

[0003] With the development of ceramic materials, new ceramic materials have the advantages of high melting point, high hardness, high wear resistance, oxidation resistance, etc. Therefore, ceramic parts have replaced some plastic insulators and are set at the ends of wiring harnesses as insulating parts between terminals. Traditional plastic pressed terminals are injection molded by placing the terminals in the mold cavity before injection molding. The terminals of ceramic parts can only be manually inserted into the molded ceramic terminals. This working mode is not only inefficient, but also automotive wiring harnesses often have multiple smaller terminals inside, so manual insertion is also difficult, and it is easy for the terminals to be bent due to inaccurate positioning of the terminal holes, which affects the product yield.

The placement block of the ceramic pre-installed dislocation component pushes the pre-installed part between the terminal and the clamping claw plate through the front and rear drive cylinders. The clamping claw plate descends to clamp the pre-installed part and then lifts it up. The placement block returns to its initial position, and the clamping claw plate drives the pre-installed part to descend and cover the terminal detection terminal. The position of the sub-plate is adjusted slightly at the same time, and then the clamping plate with the pre-assembled part is lifted, the placement block is pushed out, the clamping plate is lowered to put the pre-assembled part back and then returns to the initial position, the placement block pushes the ceramic part between the terminal and the clamping plate through the left and right driving cylinders, the clamping plate descends to take out the ceramic part, the placement block returns to the initial position, the clamping plate descends to install the ceramic part on the outer wall of the terminal, the clamping plate releases the ceramic part and returns to the initial position, the terminal claw releases the terminal and returns to the initial position, and the staff pulls out the assembled wiring harness by pulling out the handle, and the assembly can be completed by taking out the wiring harness.
