Electric couplers and component thereof

Abstract

The invention discloses electric couplers and a component thereof. An electric coupler component comprises a first electric coupler and a second electric coupler which are in butt joint. The first electric coupler comprises a first insulating body and a plurality of first terminals fixedly held on the first insulating body. The second electric coupler comprises a second insulating body and a plurality of second terminals fixedly held on the second insulating body. The first terminals and the second terminals are provided with contact portions. The same contact portion of the first terminals is provided with at least two convex portions and isolation grooves positioned between adjacent convex portions, and the contact portions of the second terminals are provided with housing portions for correspondingly housing the convex portions, thus more contact portions can be formed among the terminals and be beneficial to improving the electrical contact effect.

Description

【Technical field】 [0001] The invention relates to an electrical connector and its components, in particular to an electrical connector connected to a circuit board and its components. 【Background technique】 [0002] Please refer to Japanese Patent Application Publication No. 2007-035291, which discloses an existing electrical connector assembly, which includes a mated plug and a socket, and the plug and socket include an insulating body and a holding Several terminals on the insulating body; the socket has a docking space for accommodating the plug. The terminal of the socket is an elastic terminal and has a holding part held on the socket insulating body, and a "U" extending from one end of the holding part to the docking space is bent and extended. ”-shaped elastic contact arm and a welding portion extending from the other end of the holding portion to the outside of the insulating body. The elastic contact arm includes opposite first and second contact portions. The first...

Problems solved by technology

[0003] When the plug is inserted into the docking space of the socket, the plug terminal enters between the first and second contact parts of the socket terminal. Since the second contact part is a protruding part formed by bending the end of the socket terminal, and the surface of the protruding part It is relatively complete, so the mutual interference force between the protruding part and the groove is small, and as the number of plugging and unplugging increases, the elastic performance of the socket terminal may decrease, so that the terminals of the plug and socket are easy to separate and affect the electrical contact; and When there is foreign matter in the groove of the plug terminal, it is also not conducive to the electrical contact of the two electrical connectors.
