Embodiment

[0019] Example: such as figure 1 , figure 2 , image 3 , Figure 6 As shown, a large-current elastic contact terminal with multiple contacts in a staggered arrangement, the butt end of the contact terminal includes six contact pieces 111, 112, 113, 114, 115 and 116, and each contact piece is provided with Corresponding contact areas 1111 , 1121 , 1131 , 1141 , 1151 and 1161 . The above-mentioned contact pieces are staggeredly distributed on the a-side and b-side of the contact member, and the contact pieces 111, 114 and 115 are of the same length during blanking, which are defined as long contact pieces, and the corresponding contact areas are defined as long contact areas. Sheets 112, 113, and 116 are equal in length during blanking, and are defined as short contact sheets, and the corresponding contact areas are defined as short contact areas, and the gap between long and short contact sheets is d. Refer to Figure 6 . After the sheet metal is formed, the long contact ...

Abstract

The invention discloses an irregularly-arrayed multiple-contact large-current elastic contact terminal. The abutting end of the contact terminal is provided with a plurality of contact areas, and the contact areas are irregularly arrayed on the front surface, the back surface and a same surface of the contact; the abutting end comprises at least four contact pieces, and the contact pieces are crisscross distributed on the front surface, the back surface and a same surface of the contact based on different lengths; and each contact piece is provided with at least one contact area, and the contact areas are independent and crisscross distributed on the front surface, the back surface and a same surface of the contact. The invention scatters and reduces the insertion force that is concentrative in the past when in abutment so as to cause abutment to be loose and soft; furthermore, multiplex-contact not only increases the area of the contact areas and improves the reliability of connection, but also scatters the concentrative heating points of the contact in the contact areas during the large-current transmission process and enlarges the heat radiation channel, so that the aims such as reducing the heating amount and optimizing the heat radiation channel to improve the current carrying capacity and the connection reliability are achieved.

Description

technical field [0001] The invention relates to an elastic contact terminal applied in an electrical connector, in particular to a large-current elastic contact terminal applied in a power connector installed on a printed board. Background technique [0002] In the interconnection of electronic circuits, power connectors are essential components in the interconnection system of power circuits. Compared with contacts for transmitting signals, high-current contacts used in power connectors need to have elements such as low contact resistance and good heat dissipation conditions to meet the heat reduction and control temperature rise during high-current transmission. Such as Chinese patents CN1409445A, CN101048919A, CN1801535A, CN1574479A, CN1819345A and CN2629274Y, etc., the structures of the high-current contact terminals described in these patents all have defects such as concentrated contact area, unsatisfactory heat dissipation effect and large insertion force.
