Protection type terminal with two-sided elastic piece and low insertion force

Abstract

The invention relates to a protection type terminal with a two-sided elastic piece and low insertion force. The terminal comprises a square tube; a segmented slot is formed in the middle of the uppertube wall of the square tube; the plane where the segmented slot is located in a first plane; the square tube is symmetric with respect to the first plane; the left end of the bottom of the square tube is connected with two crimping conductor core pins; two crimping conductor sheath pins are arranged on the left sides of the crimping conductor core pins; the two crimping conductor core pins are symmetric with respect to the first plane; the two crimping conductor sheath pins are symmetric with respect to the first plane; two locking plate stop steps are arranged on the left side of the top ofthe square tube; the locking plate stop steps are symmetric with respect to the first plane; a tongue-shaped elastic piece is arranged on each of two side walls of the square tube. According to the terminal, a contact method of adding a bidirectional tongue piece elastic piece structure in the square tube is adopted, so that the plugging life is prolonged by utilizing the elastic force of the tongue piece, and the insertion force is reduced by utilizing the excessive arc chamfering manner of the tongue piece.

Description

technical field [0001] The invention relates to the field of connection terminals, in particular to a low-insertion-force protective terminal of a double-sided elastic sheet. Background technique [0002] Nowadays, most of the connector connections adopt the multi-hole integration method, which simplifies the wire connection method and improves the installation efficiency during organization. Therefore, it is necessary for the connector to have a low overall insertion force when mating, and a small insertion force when a single terminal is in contact, so as to meet the overall assembly requirements. [0003] At present, the known solution is to add a bubble point in the square tube to contact with the round needle or the four pins to realize conduction. [0004] Generally, a square tube plus bubble point contact method is used, such as figure 1 , when in contact with the pin, the pin is poured into the tube by squeezing the square tube to expand outward, and the bubble poi...

AI Technical Summary

Problems solved by technology

The square tube structure has poor elasticity, and the insertion force drops significantly after a certain amount of insertion and extraction, which affects the service life

In order to achieve low insertion force, the clearance between the contact pin and the pin will be increased. When there is too little interference between the pin and the square tube bubble point, poor conduction is likely to occur.
