BTB (Board to Board) connector

Abstract

The invention relates to a BTB (Board to Board) connector which comprises a plurality of male terminals, a male terminal main body, a plurality of female terminals and a female terminal main body. The male terminals are molded by bending and rotating a conductive material, and each male terminal comprises an elastic arm and a contact area arranged in the elastic arm; the male terminal main body is an insulating block approximate to a rectangle; the female terminals are molded by bending and rotating the conductive material, and each female terminal comprises an elastic arm and a contact area arranged on the elastic arm; the female terminal main body is an insulating block which is approximate to a rectangle, and one face of the insulating block is sunken to form a butt joint groove; the male terminals are fixed on the male terminal main body; the female terminals are fixed on the female terminal main body; and the male terminal main body and the female terminal main body are mutually inserted so as to ensure that the male terminal main body is accommodated in the butt joint groove and all the contact areas of the male terminals and the female terminals are connected in a butting way. The male terminals and the female terminals are both molded in a bending and rotating way and have the longer elastic arms; and during butting, a longer prepressing stroke is formed to increase contact elasticity of the terminals, improve contact stability and reduce contact resistance.

Description

technical field [0001] The invention relates to a BTB connector, in particular to a BTB connector with male and female terminals formed by bending. Background technique [0002] BTB connectors are mainly used for signal connections between PCBs in mobile phones and laptops, Bluetooth, hard disk cables, touch mouse boards, etc. It belongs to high-precision multi-contact connectors. There are currently 0.5mm, 0.8mm, 1.0mm, 1.27mm, 2.0mm, 2.5mm spacing and other specifications. At present, the BTB connectors produced by BTB connector manufacturers generally include a pair of male and female terminals, and the male and female terminals are often of a single blanking structure. The so-called blanking structure means that when processing the terminal, a piece of metal plate is cut in a plane, and the unnecessary plate is dug out to make the male and female terminals required for molding. Therefore, during the entire processing process of the terminal, no stretching or bending tr...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problems of small contact force, low contact stability and high contact resistance caused by the small contact pre-press stroke of the BTB connector terminal, the present invention provides a terminal contact pre-press travel with large contact force and contact stability. High, low contact resistance BTB connector

[0004] In order to solve the problem that the female terminal of the above-mentioned BTB connector is easily overturned by the male terminal, resulting in kneeling, the present invention provides a BTB connector with a female terminal with an anti-kneeling structure
