Leaf spring and electric connector

Abstract

The invention relates to an electric connector. The electric connector comprises a socket, a plug and a leaf spring arranged in the socket. A contact column is vertically arranged in the center of theleft end of the plug, the leaf spring comprises a cylindrical connecting plate which is through left and right, a plurality of elastic pieces are uniformly and vertically connected to the right end face of the cylindrical connecting plate in the circumferential direction, the tail end of each elastic piece is a contact plate, and each contact plate is bent towards the inner side. Respective contact surfaces of the plurality of contact plates jointly form an envelope contact surface matched with the contact column. The leaf spring is simple in structure and low in production cost, adopts an enveloping surface contact mode, is large in contact area, is more stable in connection, can prevent the socket and the plug from loosening, and guarantees the stability and reliability of the electricconnector. In addition, the large contact surface area can also increase the over-current area, thereby preventing the service life of the electric connector from being shortened and avoiding the electric connector from being damaged due to temperature rise when the electric power is too high. The electric connector provided by the invention can effectively ensure the safe operation of an electrical system.

Description

technical field [0001] The invention belongs to the technical field of electrical connectors, and in particular relates to a leaf spring and an electrical connector. Background technique [0002] The existing electrical connector is mainly composed of a plug, a socket and a leaf spring, and the leaf spring is installed in the socket to play an important role of contact and conduction. According to the knowledge of the inventor, most of the existing leaf springs and plugs are in point contact or line contact, the contact area is small, and the flow-through capacity is relatively poor. When the electrical power is large, it is easy to cause the temperature to rise and affect the service life of the electrical connector. [0003] On the other hand, as the basic component of the electrical system, the reliability of the connection of the electrical connector is an important indicator. In view of this, how to ensure that the plug and the socket are not easy to loosen, so as to ...
