Electrical connector and its terminal set

The present invention provides an electrical connector and a terminal set thereof, especially the width of the front flattening of the terminal component type and the width of the continuous stamping and bending forming, so that the terminal group and the material strip can be assembled in one place at a time. In the body to improve the efficiency of the overall assembly work.

According to the rapid development of electronic technology, electronic devices such as computers, notebook computers, and liquid crystal displays have become commonplace in all corners of society. Because of the current trend of electronic devices, they tend to be light, thin, short, and small. The assembly space of the plurality of cables inside the electronic device and the circuit board can be used to become narrower and smaller, and the common method is to achieve electrical connection with the circuit board through the wire-to-board connector. Connector sizes have become smaller and smaller, and various types of connectors have been developed.

Please refer to the eighth, ninth and tenth figures, which are the three-dimensional appearance of the conventional conductive terminal, the front view before molding and the front view after molding. It can be clearly seen from the figure, wherein the conventional conductive terminal A is made of metal sheet. The body stamping is bent and formed, and has a terminal body A1, and the opposite side arm A2 is disposed at two sides of the terminal body A1, and the two side arms A2 are respectively bent downward to extend the contact arm A21, and the terminal body A1 is A connecting portion A3 having a crimping groove A31 is provided at a joint with the side arm A2, and a connecting portion A4 having a crimping groove A41 is also provided at the other side of the connecting portion A3.

However, the conventional conductive terminal A still has many defects in practical use, and since the conductive terminal A is flattened, the wider portion is the side arm A2 extended by the joint portion A3 of the U-shaped crimping groove A31 and The side arm A2 is further extended from the contact arm A21, and the conductive terminal A is formed by bending the metal sheet body through continuous stamping. Each of the conductive terminals A needs to be connected by a strip A0, but the width of the conductive terminal A is flattened. Wide, and the distance d1 between adjacent conductive terminals A can not be shortened compared with the distance d2 between stamping and bending. When the conductive terminals A are assembled inside the plastic body, if the adjacent slots on the plastic body are adjacent, The width spacing between the (not shown) is smaller than the distance d2 of the plurality of conductive terminals A, which will cause the conductive terminal A of the continuous press and bend forming to be inserted into the plastic body once in a state of being connected with the tape A0. There is a problem that a single conductive terminal A is assembled or a plurality of conductive terminals A are used for interval assembly, and the number of assembly presses is increased, and the assembly work efficiency is also poor.

Furthermore, the contact arm A21 of the conductive terminal A is bent at two sides of the terminal body A1 to extend out of the opposite side arm A2, and then bent and extended by the side arm A2 in multiple stages, the continuous stamping and bending forming contact arm A21 will improve the difficulty in designing and manufacturing the mold, and the distance d2 between the conductive terminals A will be relatively widened, and too much waste area will be generated, which will result in waste of materials and cost. The spacing between the two contact arms A21 of the stamping and bending forming is not easy to maintain, and after the crimping groove A31 on the connecting portion A3 is pressed into the wire, it is also easy to be pressed by the connecting portion A3 to cause the distance between the two contact arms A21.
