Abstract
This invention relates to a power connector, used for electric connecting the first circuit board to the second circuit board, and it includes the insulation body and the conductive terminal accepted by the insulation body. The conductive terminal has the base and the contacting part connecting with the second circuit board, and at the two ends growing vertically from the base, it has at least two connecting parts contacting with the first circuit board. When the power connector connects to the second circuit board, because of its two relative ends of the base both contacting the first circuit board, even if the conductive terminal takes too much pressure, it still can maintain balance, not tilted, thus ensuring that the contacting part of the conductive terminal normal connects with the contact region of the second circuit board corresponding to the conductive terminal.
Description
[technical field]
The present invention relates to a kind of electric connector, refer to a kind of electric connector that electrically connects first circuit board to second circuit board especially, wherein, this electric connector is to be electrically conducted with face contact mode and second circuit board.
[background technology]
Existing a kind of electric connector that electrically connects first circuit board to second circuit board, the plurality of conductive terminals that it comprises insulating body and is contained in insulating body.See also Fig. 1, the conducting terminal 90 of this electric connector be provided with location conducting terminal 90 in insulating body hold plate 91, this holds first plane 912 that plate 91 has contiguous first circuit board.Be provided with weld part 92 in an end that holds plate 91, this weld part 92 is welded on the first circuit board, and it is provided with the solder side 921 that is parallel to first plane 912.First plane 912 and solder side 921 are positioned on the differing heights layer with respect to first circuit board.Extend elastic arm 93 that continuous bend be set along the direction that deviates from first circuit board from holding plate 91 near weld part 92 1 ends, its end is provided with the contact site 94 that connects mutually with second circuit board.
