Description

Electrical Connector Assembly

【Technical field】

The utility model relates to an electrical connector assembly, in particular to an electrical connector assembly combining a voice socket and an interactive digital video system (DVI) socket.

【Background technique】

In response to the development trend of the computer industry, the power supply and signal transmission connectors in the computer also need to be designed accordingly, so that the equipment that is upgraded simultaneously with the computer can be smoothly connected to the printed circuit board. The input and output electrical connectors in the existing printed circuit board are mostly arranged on one edge of the board, and a socket port is formed on the rear shell board so as to conduct with various peripheral devices. However, with the rapid expansion of peripheral devices, the socket ports provided by the traditional arrangements are no longer sufficient. Therefore, it is an effective method to solve these problems to use the frame to stack the connectors, and then insert them on the printed circuit board to increase the usable space. For related prior art, reference may be made to Taiwan Patent Application No. 80208088 and US Patent No. 5,080,609. However, due to the presence of multiple connectors in one frame, the coordination between the connectors is relatively cumbersome, which is quite a waste of man-hours.

Fig. 9 is a kind of existing electrical connector assembly, and this electrical connector assembly utilizes frame to stack each connector, and it comprises bracket 40, first connector 41, second connector 42 and third connector 43, and the first A connector 41 , a second connector 42 and a third connector 43 are mounted on the bracket 40 respectively. Fitting holes 410, 420, 430 and 400 are respectively provided on the first connector 41, the second connector 42, the third connector 43 and the bracket 40, and the electrical connector assembly utilizes the fitting holes and the screw 50 and the rivet 51 to cooperate with each other. So that each connector is fixed on the bracket. With this method, each connector can be firmly attached to the bracket, but the process of disassembling each connector from the frame is relatively cumbersome. Moreover, due to the need for screw-lock cooperation, the number of processing steps is increased, and it is difficult to reduce the assembly cost.
