Interplate contact device, printed board component and printed board group

Abstract

The invention relates to the field of electric connectors, in particular to an interplate contact device, a printed board component and a printed board group. The interplate contact device comprises asupport body and an elastic contact piece, the support body comprises a fixing part used for fixedly matching with a corresponding printed board and a supporting part used for installing the elasticcontact piece, the elastic contact piece comprises at least one spiral spring sleeving the supporting part of the support body, more than two conductive contact parts are arranged at the outer peripheral surface of the spiral spring in the circumferential direction, each conductive contact part is used for being in conductive contact with the corresponding printed board to be connected respectively, the arrangement of the conductive contact parts around the support body meets the requirement that when the elastic contact piece is pressed by the printed boards, the elastic contact piece is pressed between the printed boards and is in abutting contact with the printed boards, and an avoidance gap is arranged between the position at the inner side of the at least corresponding conductive contact part of the elastic contact piece and the supporting part. The problems are solved that the connection device of the printed board is high in cost, and is poor in through-current capability.

Description

technical field [0001] The invention relates to the field of electrical connectors, in particular to an inter-board contact device, a printed board component and a printed board group. Background technique [0002] With the rapid development of miniaturization and modularization of various electrical equipment and electronic equipment, printed board products with specific functions continue to increase. At present, it is often encountered that two printed board components are electrically connected to each other. [0003] In the prior art, in order to realize the electrical connection between two printed boards, a male connector is fixed on one of the two printed boards, and a female connector is fixed on the other. figure 1 It shows the separation state of the first printed board 2 with the female connector 1 installed and the second printed board 4 with the male connector 3 installed, figure 2 It shows the connection between the above-mentioned first printed board 2 and ...
