Board-to-board connector

Abstract

The invention discloses a board-to-board connector. The board-to-board connector comprises an insulating body extending in the longitudinal direction, terminals fixedly held on the insulating body, and protection brackets located at the two longitudinal ends of the insulating body. The protection brackets are fixed on end walls and are provided with end wall shielding sheets which cover end wallsand side wall shielding sheets which at least partially cover side walls. The side wall shielding sheets are connected with the two transverse ends of the end wall shielding sheets. Each end wall shielding sheet comprises an end wall shielding part which covers the top face of each end wall and an outer wall shielding part which is bent from the side edge of the above end wall shielding sheet andcovers the outer wall face of the end wall. Each outer wall shielding sheet comprises elastic arms extending from the two transverse ends of the outer wall shielding sheet along the inner wall faces of the side walls. The elastic arms of the protection brackets are provided with long force arms. According to the invention, the problem that the elastic arms are large in descending after the board-to-board connector is inserted and pulled out is solved while stable assembly of the board-to-board connector is guaranteed. The contact of the board-to-board connector is stable and reliable when theboard-to-board connector is used.

Description

technical field [0001] The invention relates to a board-to-board connector, in particular to a board-to-board connector with a metal protection bracket. Background technique [0002] Board to Board Connector (BTB for short) is a kind of connector often used in electronic equipment (such as mobile phones, tablet computers, etc.), and its function is to realize the connection between the main board of the electronic equipment and each module (such as a display module). group, touch module, camera module, etc.) between mechanical and electrical interconnections. A board-to-board connector is usually composed of a plug and a socket. The plug and socket are composed of a plastic body and a conductive terminal held on the plastic body. The plastic body mainly plays the role of insulating and positioning the conductive terminal. The conductive terminal The main function is conduction. Usually, the plug and socket of the existing board-to-board connector will also add a protective...

Problems solved by technology

However, due to the limited height of the insulating body of the socket, the force arm of the shrapnel is relatively short, that is, the yield of the shrapnel is too large, and the power of the shrapnel is significantly attenuated after the socket is plugged in, so that the contact stability of the board-to-board connector is poor; The protective brackets at both ends of the existing socket fail to protect the front and inner plastic of the insulating body, resulting in damage to the insulating body of the socket after the board-to-board connector is assembled, and abnormal situations such as improper assembly are prone to occur
