Connector

Abstract

The invention relates to a connector, comprising a shell with an FPC / FFC jack; first, second terminal groups respectively inserted / arranged on the shell from the jack direction and the opposite direction of the jack; a brake supported by the terminal of the second terminal group; an outer cover, wherein the first terminals of the first terminal group are in '-' shape; the second terminal of the second terminal group comprises a rotary motion support part, a second contact part and an elastic support part at the end of the forked terminal arm; a cam of the brake is arranged between the rotary motion support part and the second contact part; the first, second terminals of the first, second terminal groups are arranged at different intervals; the outer cover comprises a first pressing part for pressing the FPC / FFC; the first terminals is linklocked with the first pressing part to make the upper surface of the first contact part contact with the corresponding terminal on the FPC / FFC lower surface; when the second contact part drops together with the rotation of the cam, the second terminal contacts with the corresponding terminal of the FPC / FFC upper surface inserted between the second contact part and the elastic support part.

Description

technical field [0001] The present invention relates to a joint, in particular, to a terminal that is pressurized by a brake or an outer cover to connect a flexible printed circuit board (FPC, Flexible Printed Circuit) or a flexible flat cable (FFC, Flexible Flat Cable) to a circuit board. connected connectors. Background technique [0002] Recently, as electronic products have become increasingly miniaturized, connectors are also required to be miniaturized, and the functions of electronic products are also becoming more diverse, requiring more transmission circuits. Therefore, connectors are also required to have multiple terminals. [0003] In order to have a plurality of terminals, if the terminals are arranged in one row, there is a limit to the miniaturization of the connector. Therefore, in many cases, the terminals are arranged in two rows. [0004] For example, if figure 1 As shown, Korean Registered Patent No. 443043 discloses a connector, which has a first termi...

AI Technical Summary

Problems solved by technology

[0006] Both terminal groups have contact parts 14, 24 that apply elastic pressure to the FPC / FFC from the lower surface of the socket to the upper surface. Therefore, the more terminals in the terminal group, the greater the pressure of the contact parts 14, 24 on the brake 40. , so that the brake 40 cannot work smoothly

[0007] In addition, the two terminal groups have to bear the pressure of the brake. Therefore, in order to be effectively supported by the shell, it is often necessary to thicken or provide additional fixing parts. The overall weight of the joint will also increase, and at the same time, in order to support the pressure of the brake, the shell should also be set very thick

[0008] In addition, the above-mentioned connectors only alternately arrange terminals on one side of the FPC / FFC. Therefore, only FPC / FFC of a specific specification can be fixed, and its application range is narrow, and it also has limitations in increasing the terminal density.
