Board-to-board electric connection device and electric appliance module

Abstract

The invention discloses a board-to-board electric connection device. A fixing base is fixedly installed on a first electric appliance plate to provide support, the fixing base is connected with an electric connecting piece through an elastic supporting piece, and the elastic supporting piece is used for supporting the electric connecting piece and can be elastically bent and deformed. The electricconnecting piece is overturned and translated relative to the fixing base under the elastic effect, and the fixing base and the electric connecting piece are not in rigid connection. When the electric connecting piece and an electric connection hole on the second electric appliance plate are assembled in a plug-in manner, and if tolerance exists, the electric connecting piece can generate elasticdeformation through the elastic supporting piece, stress is prevented from being generated between the fixing base and the first electric appliance plate, the contact stress between the electric connecting piece and the second electric appliance plate is small, micro-motion abrasion of the electric connecting piece is effectively avoided, and a contact plating layer is prevented from failing.

Description

technical field [0001] The invention relates to the technical field of electrical connection, and further relates to a board-to-board electrical connection device. In addition, the present invention also relates to an electrical module. Background technique [0002] The common electrical connection methods in electronic modules are wire-to-wire connection, wire-to-board connection, board-to-board connection, and conductive connection through wires or metal connecting sheets; the consistency of wire-to-wire connection and wire-to-board connection is poor, the assembly is cumbersome, and the wiring The board-to-board connection adopts the plug-in connection, which has good consistency and simple assembly. Due to the large number of connection points, the position of the plug is required to be high, and tolerances are prone to occur.

AI Technical Summary

Problems solved by technology

[0002] The common electrical connection methods in electronic modules are wire-to-wire connection, wire-to-board connection, board-to-board connection, and conductive connection through wires or metal connecting sheets; the consistency of wire-to-wire connection and wire-to-board connection is poor, and the assembly is cumbersome. Difficult; while the board-to-board connection adopts plug-in connection, which has good consistency and simple assembly. Due to the large number of connection points, the requirements for the position of the plug are high, and tolerances are prone to occur

[0003] The traditional board-to-board connection structure adopts the form of hard connection, the connecting piece is prone to fretting corrosion, and the contact area is prone to fretting wear, which will cause the coating of the contact to fail after wear, and the exposed metal will oxidize and corrode, resulting in the connection of the contact The impedance increases and the connection fails

[0004] For those skilled in the art, how to avoid corrosion failure caused by the wear of the connecting piece is a technical problem that needs to be solved at present.
