Background Art

In the process of manufacturing the connector, sometimes, it is necessary to insert the conductive terminals on the connector into the connector housing and then bend them at a predetermined angle, for example, 90 degrees.

In the prior art, the terminal is generally inserted into the connector housing manually. However, only one conductive terminal can be inserted at a time by manual insertion, and the efficiency is low. Therefore, the insertion cost is high and the efficiency is very low.

In addition, the accuracy of manual insertion of terminals is difficult to ensure, and the wrong position is often inserted, resulting in terminal damage. This will make it difficult to correctly install the damaged conductive terminals on the circuit board, reducing the conductive performance of the conductive terminals and causing terminal waste and rework.

In addition, during manual bending, workers need to use tools such as pliers to clamp the conductive terminals, which may form scratches on the surfaces of the conductive terminals, thereby reducing the quality of the conductive terminals.

In order to solve the above problems, the prior art provides corresponding connector terminal bending equipment. However, due to the large number of terminal types, frequent switching is required, resulting in a large number of manual line changing equipment, which occupies production line space. Secondly, the bending and forming effect of manual line signal pins is unstable, resulting in a large number of scraps, a large amount of manpower, extremely high manual work intensity, and low work efficiency.
