Intermediate electrical connector device and its connecting structure
An intermediate electrical connector device, which easily enables “floating”, includes an intermediate board ( 20 ) having two connecting sections ( 23 A) and ( 24 A), which are respectively formed at the edges ( 23 ) and ( 24 ), to connect between two connecting bodies ( 40 ) and ( 40 ′), and a holding body to hold the intermediate board between two connecting sections. The holding body is divided into a plurality of sub-members ( 10 ) and ( 10 ′) at a surface perpendicular to the fitting direction between the two connecting bodies. The intermediate board is held by one of the sub-members through at least partial fitting, and forms space from another sub-member. The sub-members can be displaced relative to each other on the surface perpendicular to the fitting direction at least one direction parallel and perpendicular to the intermediate board.
