As shown in Figures 1 and 2 of the existing curved contact pieces, the first flange is generally provided with a boss 10 and a non-rotation plane 11, and the boss 10 is used to stop and cooperate with the ring groove on the insulator and ensure that The insertion depth when it is inserted into the insulator, the anti-rotation plane 11 is used to cooperate with the matching plane in the ring groove on the insulator and prevent the relative rotation between the contact piece and the insulator, so as to ensure that the second flange is facing the insertion direction of the pressure plate to facilitate the insertion of the pressure plate assembly.

However, this kind of bent contact piece has many steps in processing and the cost is high. For example, the curved contact piece of φ5 may need the positioning step of φ7, and the blank material of φ8 is required for processing, so that turning off more blanks will cause waste of raw materials. And arranging the boss makes the diameter of the curved contact piece larger, so when the contact piece is processed with a coating, it is necessary to adopt the rack plating process to process the coating, so that the hook plating hole will be set on the contact piece, which not only increases the processing of the rack plating hole. process, and the plating efficiency is low.

Of course, there are also some bent connectors in the prior art, the bent contacts of which are fixed in the insulator by potting glue, or are directly injected into the insulator, but the glue of the connector fixed by potting takes a long time to cure. Long, the connector processing process of the direct injection molding of the contact piece is more troublesome.
