Abstract

The invention provides a contact element pair structure for an electric connector. A drum-shaped contact pin contact element is connected with a jack contact element in a pluggable mode. The drum-shaped contact pin contact element comprises a drum-shaped body and a movable rod capable of vertically moving in the drum-shaped body, a plurality of protruding blocks corresponding to elongated openings are arranged in the circumferential direction of the movable rod, each protruding block is in rotatable connection with the movable rod, and each protruding block penetrates through and slides in the corresponding elongated opening. The jack contact element is provided with cylindrical elastic holes, and the inner sides of the upper portions of the cylindrical elastic holes are provided with limiting rings used for limiting the protruding blocks. According to the contact element pair structure for the electric connector, the reliability of connection between the drum-shaped contact pin contact element and the jack contact element is strong, reliability is further improved due to the matching between the protruding blocks and clamping grooves, threaded connection between clamping parts, the drum-shaped body and the movable rod and arrangement of the limiting rings and the like, and therefore the reliability of the contact element pair structure for the electric connector is greatly improved.

Description

technical field [0001] The invention belongs to the field of connectors, and in particular relates to a contact piece pair structure for an electrical connector. Background technique [0002] The electrical connector product completes the current and signal connection work, which is mainly performed by the core component of the electrical connector - the contact piece. The contact piece is composed of a pin contact piece and a jack contact piece. Through the connection between the pin and the jack, the current flow is realized. and signal connection. Contact performance is directly related to the quality of current and signal transmission. The reliability of the existing contact piece is relatively poor, and phenomena such as poor contact are prone to occur, which affects normal use. Contents of the invention [0003] In order to solve the above problems, the present invention provides a contact pair structure for an electrical connector, including a drum-shaped pin cont...
