Board to board connector used for mobile terminal and PCB connection structure

Abstract

The invention discloses a board to board connector used for a mobile terminal. The connector comprises an insulator, a connector pad and a connector contact spring sheet, wherein the connector pad and the connector contact spring sheet are arranged on the insulator. The insulator is a right-angle-strip-shaped connecting piece. One side of the connector contact spring sheet is vertically connected to one side of the connector pad. A lighting and thinning design is integrally satisfied. The structure is simple and assembling reliability is good. A PCB connection structure adopting the board to board connector can be thinner. The connector pad is welded and fixed to a PCB pad of a first PCB. The connector contact spring sheet located on one side of the first PCB is contacted with a PCB contact goldfinger of one side of a second PCB so that the first PCB and the second PCB are electrically connected. A transmission stroke of a signal between the PCBs is shortened and transmission quality of the signal is increased. Simultaneously, an assembling height during board grade connection is reduced maximumly, a structure space in the mobile terminal is saved and a thinning tendency need of the mobile terminal in a market is satisfied.

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.
