1. A contact fixing structure with secondary positioning is composed of a contact (1) and an insulator (2); the method is characterized in that: the contact piece (1) is provided with a barb (3) which is penetrated into the insulator (2) to prevent the contact piece (1) from returning back to form a one-time positioning structure; after the contact (1) is installed in the insulating part (2), the bending structure (4) is formed through punching, the contact (1) is prevented from returning, and a secondary positioning structure is formed.

Technical Field

The invention relates to a contact fixing structure with secondary positioning, belongs to the technical field of electric connectors, and is suitable for occasions with higher requirements on the reliability of the contact fixing structure.

Background

At present, an electric connector adopting an integrated insulation part structure usually realizes the positioning between a contact part and an insulator through a barb structure on the contact part, and the structure has the following defects:

in the place with severe application environment, the effect of long-term temperature stress cycle, ray irradiation and mechanical stress can accelerate the aging of the insulator, thereby causing the failure of the fixing function of the contact.

According to the invention, through the bending structure of the contact terminal, the secondary positioning between the contact and the insulator is realized, and the reliability of the contact fixing structure is effectively improved.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide a contact fixing structure with secondary positioning, which can effectively improve the reliability of the contact fixing structure.

The technical scheme adopted by the invention is as follows: a contact fixing structure with secondary positioning is composed of a contact and an insulator; the contact piece is provided with a barb, and after the barb pierces the insulator, the contact piece is prevented from returning through the deformation of the insulator, so that a one-time positioning structure is formed; after the contact element is installed in the insulating part, the bending structure is formed through punch forming, the retraction of the contact element is prevented, and a secondary positioning structure is formed.

The invention has the advantages that: after the contact penetrates into the insulating part, the bending structure is formed through punching, secondary positioning of the contact fixing structure is achieved, and compared with a primary positioning contact fixing structure, the structure has higher reliability.
