Cage leaf spring and socket and electrical connector using the leaf spring

Abstract

The invention relates to a cage type leaf spring, a jack using the same and an electric connector. The cage type leaf spring is composed of a front end ring, a back end ring and a connecting linear spring bar integrally arranged between the front end ring and the back end ring; the positioning columns of corresponding torsion fixtures can be inserted into the inner holes of the front end ring and the back end ring in a matched manner along an anterior-posterior direction; the front end ring and the back end ring are provided with rotation stopping keyways; and the rotation stopping keyways are in rotation stopping plugging matching with rotation stopping keys on the corresponding torsion fixtures, and therefore, under the action of the torsion fixtures, the connecting linear spring bar can form a hyperboloid structure which defects together with the axes of the front end ring and the back end ring, the extension direction of the hyperboloid structure intersecting with the axis space of the front end ring and the back end ring. With the cage type leaf spring adopted, the problem of complex operation of molding a connecting linear spring bar into a hyperboloid structure in the prior art can be solved.

Description

technical field [0001] The invention relates to a cage-type leaf spring and a socket and an electrical connector using the leaf spring. Background technique [0002] In the field of electrical connectors, the main design indicators for contacts used to transmit large currents are temperature rise and plug-in life. Many military and civilian electronic equipment have strict regulations on temperature rise. If the temperature rise is too high, it means that there are operators. The risk of scalding, the high temperature rise also means that the ambient temperature that the equipment is allowed to work is reduced, which limits the application in some occasions (such as around the engine, etc.). High plug-in life means cost reduction, especially for some applications Important (such as electric vehicle charging gun). In-depth analysis shows that the most important factor in temperature rise and plug-in life is the plug-in force of the contact. The plug-in force determines the co...
