A board-to-board connector and pcb board connection structure for mobile terminals

Abstract

The invention discloses a board-to-board connector for a mobile terminal, which includes an insulator, a connector pad and a connector contact elastic piece arranged on the insulator, the insulator is a right-angle strip-shaped connector, and the connector One side of the contact shrapnel is vertically connected to one side of the connector pad. Overall, it satisfies the light and thin design, and has a simple structure and good assembly reliability, so that the PCB board connection structure using the board-to-board connector can be made thinner, and the connector pad is welded and fixed on the PCB of the first PCB board On the pad, the connector contact shrapnel on the side of the first PCB is in contact with the gold finger of the PCB on the side of the second PCB, so that the first PCB and the second PCB are electrically connected, which not only shortens the signal on the PCB. The transmission stroke between the boards improves the signal transmission quality, and at the same time minimizes the assembly height of the board-level connection, saves the structural space inside the mobile terminal, and satisfies the pursuit of thinner mobile terminals in the market .

Description

technical field [0001] The present invention relates to the technical field of PCB boards, and more specifically, relates to a board-to-board connector for a mobile terminal and a PCB board connection structure. Background technique [0002] With the development of mobile terminals, thinness has become a prominent pursuit of aesthetics for users. The design requirements for thinner and lighter devices are becoming more and more obvious. [0003] In the design of the mobile terminal, many board-to-board connectors are used to realize the board-level interconnection of hardware signal communication. Only edge connectors or strip connectors are used to realize the connection, and pin headers are also used to complete the connection. Common board-to-board connectors include BTB sockets, ZIF sockets, and coaxial cables. [0004] This type of board-to-board connector has the problem of large volume, and there is an assembly height in the board-level connection, which often becom...

Problems solved by technology

[0004] This type of board-to-board connector has the problem of large volume, and there is an assembly height in the board-level connection, which often becomes a local bottleneck for thinning the thickness of the whole machine, affecting the thinning of the whole machine; as the structure becomes more and more compact, small The requirements for modernization are getting higher and higher, so the large volume is already an outdated product, and a large amount of materials are still required. The general BTB is composed of two independent parts, a male head and a female seat. When using, install the two parts on the When using two PCB boards, reverse the two PCB boards and buckle them together. The male head is inserted into the female seat to realize electrical and mechanical connection. This kind of structure has relatively many parts, and the male head and the female seat may be installed incorrectly during use.
