Technical Field
[0001] The utility model relates to the field of terminal assembly equipment, in particular to a terminal pin position correction jig. Background Art
[0002] The needle body in the connector industry is often assembled into the plastic shell only through the plastic shell limiter. The precision of the needle body and the plastic shell produced by traditional design is low, and the position deviation of the needle body after assembly is large. The large position deviation leads to a large plug-in and pull-out force of the connector, and also causes abnormal welding of the needle body at the board, which easily leads to electrical performance failure. This requires the precision of the needle body and the plastic shell to be particularly high, but the high-precision production of the needle body and the plastic shell will inevitably increase the product cost. Therefore, designing a fixture that can quickly and accurately assemble and correct the position of the needle body under the conditions of low-precision needle body and plastic shell is exactly the problem that the inventor wants to solve.

[0008] Compared with the prior art, the utility model has the following advantages: the terminal plastic shell is sleeved on the product support seat, and then the needle body is inserted into the needle body limiting hole on the product support seat. The needle body limiting hole can limit the front and back and left and right positions of the needle body to ensure the position and flatness of the needle body. Then the needle body riveting assembly is pressed down to press the needle body into the terminal plastic shell. At this time, the upper end of the needle body is inserted into the secondary correction hole of the needle body, so that the front and back and left and right positions of the needle body can be secondary corrected at the same time, until the needle body is pressed into the terminal plastic shell to complete the final pressing. In this scheme, the needle body riveting assembly is composed of a clip and a pressure plate, and the product support seat is composed of a positioning hole cover plate and a needle body fixing fixture. It has a split design, is easy to process, and has low cost. BRIEF DESCRIPTION OF THE DRAWINGS
