A contact piece fixing structure with secondary positioning is composed of a contact piece and an insulator. Barbs are designed on the contact piece, and the contact piece is prevented from retreating after penetrating into the insulator, so that a primary positioning structure is formed. After the contact piece is installed in the insulator, a bending structure is formed through punching, the contact piece is prevented from retreating, and a secondary positioning structure is formed. The contact piece fixing structure has the advantages that after the contact piece penetrates into the insulating piece, the bending structure is formed through punching, secondary positioning of contact piece fixing is achieved, and the reliability of the contact piece fixing structure is improved.
Description
technical field [0001] The invention relates to a contact fixing structure with secondary positioning, belongs to the technical field of electrical connectors, and is suitable for occasions requiring high reliability of the contact fixing structure. Background technique [0002] At present, the electrical connector with an integrated insulator structure often realizes the positioning between the contact and the insulator through the barb structure on the contact. This structure has the following disadvantages: [0003] In places where the application environment is relatively harsh, the long-term temperature stress cycle, ray irradiation and mechanical stress will accelerate the aging of the insulator, which will lead to the failure of the fixing function of the contact. [0004] The invention realizes secondary positioning between the contact piece and the insulator through the bending structure of the terminal of the contact piece, and effectively improves the reliability ...
