Circumferential anti-rotation structure

Abstract

The invention relates to a circumferential rotation-stopping structure which comprises a plate-shaped main body, wherein an upper rotation-stopping plate is integrally upward bent at the left end of the plate-shaped main body; the upper rotation-stopping plate is provided with a left plane which is pasted relative to a left hole wall of a corresponding mounting hole for use; a lower rotation-stopping plate is integrally downward bent at the right end of the plate-shaped main body; the lower rotation-stopping plate is provided with a right plane which is pasted relative to a right hole wall of the mounting hole for use; the extending directions of the left plane and the right plane are vertical to the left and right direction. The invention provides the circumferential rotation-stopping structure by which machining manufacturing is not required and is capable of reducing the manufacturing cost.

Description

Technical field [0001] The invention relates to a circumferential rotation stop structure. Background technique [0002] In actual production and life, the circumferential rotation stop structure is often used. For example, in the field of electrical connectors, the contact piece needs to be installed in the contact installation hole of the insulator through the circumferential rotation stop structure. The existing electrical connector includes an insulator. The insulator is provided with a contact mounting hole extending in the front-to-rear direction. The contact mounting hole is provided with a contact with a plug-in end at the front end. In order to ensure that the contact is firmly fixed, the contact generally passes through The circumferential rotation stop structure and the axial limit structure cooperate with the insulator, the circumferential rotation stop structure can prevent the contact piece from rotating circumferentially relative to the insulator, and the axial lim...

AI Technical Summary

Problems solved by technology

The problem with the existing contact pieces is that the circumferential anti-rotation structure and the contact pieces are generally machined from copper rods, for example, the copper rods are machined into a square structure, and the square structure and the square contact piece of the insulator The mounting hole is adapted to plug-in to achieve anti-rotation. For contacts with small structural dimensions, the material-removing molding process is not easy to manufacture, and the cost of machining is high, and the efficiency is low, resulting in high product cost of the connector. , the price of a set of 6-cavity products is around 10,000 yuan, which is very unpopular
