Technical Field

The utility model relates to a connector field, especially a socket and connection structure thereof.

Background

POGO PIN is an elastic small PIN with a spring, and is called a spring PIN for short. The main functions of POGO PIN are: charging, mechanical fastening, radio frequency, video, antenna, data, etc. POGO english interpretation is the meaning of seesaws, and PIN usually refers to a small needle-like object.

The conventional spring needle is manufactured by riveting and pressing a needle shaft, a needle tube and a spring through precision equipment, the opening of the POGO PIN needle tube is curled, the needle head is kept in the needle tube, and the spring provides contact force to enable the needle head to be fixed with a butt joint.

Compared with the traditional connection mode, the POGO PIN connector has the following advantages: long service life, high current resistance, easy cleaning, short development period, simple connection, low contact resistance, corrosion resistance and the like.

POGO PIN is widely applied to precise connection in electronic products such as mobile phones, communication, automobiles, medical treatment, aerospace and the like, plays a role in connection, and can improve the corrosion resistance, stability and durability of the connectors. Since the P0G0PIN is a very fine probe, the application in a precision connector can reduce the weight and the volume of the appearance of the connector, and the connector can be more fine and beautiful.

POGO PIN connectors in the industry at present work with single heads and can not realize double-head operation.
