This application claims the benefit of Chinese Patent Application No. CN202211082509.6 filed on Sep. 6, 2022, in the State Intellectual Property Office of China, the whole disclosure of which is incorporated herein by reference.
The present invention relates to an electrical connection assembly and an electrical connection device comprising the electrical connection assembly.
In the prior art, electrical connections between circuit boards may be realized via electrical connectors, such as a board end connector on the circuit board and a cable end connector on the cable mated thereto. However, this solution requires the provision of two board end connectors and two cable end connectors, resulting in higher costs. Another solution for connecting circuit boards includes the use of a flexible flat cable (FFC) or flexible printed circuit board (FPC), which is directly soldered to the circuit board. However, welding of FFCs or FPCs is relatively difficult.
According to an embodiment of the present disclosure, an electrical connection assembly includes a first insulator, a first adapter circuit board defining a first hole, a first connection terminal fixed to the first insulator, and a flexible connection member. The first connection terminal includes a first press fitting part pressed into the first hole of the first adapter circuit board and electrically connected to the first adapter circuit board, and a second press fitting part protruding from the first insulator and adapted to be pressed into a second hole of a first circuit board to be electrically connected to the first circuit board. The flexible connection member includes a connection conductor electrically connected to the first adapter circuit board.
The invention will now be described by way of example with reference to the accompanying Figures, of which:
Exemplary embodiments of the present disclosure will be described hereinafter in detail with reference to the attached drawings, wherein the like reference numerals refer to the like elements.

In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. It will be apparent, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are schematically shown in order to simplify the drawing.
