Connection structure of energy storage connector

Abstract

A connection structure for an energy storage connector provides ease of installation and removal, prevention of incorrect insertion, and allowance of 360-degree rotation (for the entire cable). It includes a combination of a male terminal module and a female terminal module. The male terminal module has a handle and a head for connecting the handle. The head has an outer wall, an inner wall, a insertion cavity, and at least three limiting portions on the inner wall. The head also has a insertion sleeve and a conductive portion within the insertion sleeve. The female terminal module has a secondary insertion sleeve, which has a secondary outer wall, a secondary inner wall, and a secondary insertion cavity. A secondary conductive portion is provided within the secondary insertion cavity. When the insertion sleeve is inserted into the secondary insertion sleeve to form an electrical connection, the secondary outer wall of the female terminal module forms at least three tangent points with (or tangent to) the limiting portions of the male terminal module, forcing the secondary insertion sleeve to be confined or surrounded within the insertion cavity to achieve a stable connection.
