A base of a connector defines an accommodation portion for accommodating a card-type device. The base has holding portions with surfaces directed to the accommodation portion. The holding portions hold held portions of terminals 40. Heat conductive members are provided on the surfaces of the holding portions. The heat conductive members are sandwiched between the card-type device and the holding portions when the card-type device is connected to the connector 10. In this way, heat conductive paths, which include the conductive members, are formed between the card-type device and held portions of the terminals 40.

A communication system includes a first circuit card assembly having a first PCB and a first electrical connector having a receptacle housing and a mating housing received in the receptacle housing and being movable in the receptacle housing in a connector mating direction along a connector mating axis. The second circuit card assembly includes a second PCB and a second electrical connector having a header housing holding second contacts. The first PCB and/or the second PCB includes a slot receiving the other PCB in a board loading direction. The receptacle housing is coupled to the header housing in the board loading direction and the mating housing is movable within the receptacle housing toward the header housing in a connector mating direction generally perpendicular to the board loading direction.

Sockets that have a simplified design and are readily manufactured, and also provide easy access for users to change cards while allowing the use of thinner device enclosures.

A connector assembly arrangement comprising, disposed on the faces of a circuit board in an electronic device, connector assemblies which, along with having a plug connector that incorporates a photoelectric conversion element capable of converting optical signals and electrical signals from one to the other and a receptacle connector with which said plug connector is mated, have the plug connector and the receptacle connector electrically connected through mutual contact between terminals; wherein the plug connector, from which a fiber optic cable for optical signal transmission that is connected to the photoelectric conversion element extends in one direction from said plug connector, also has terminals connected to the above-mentioned photoelectric conversion element; the fiber optic cable is a single fiber optic cable; and a plurality of connector assemblies are disposed on at least one of the two faces of the circuit board.

A connector assembly involving a plug connector that incorporates a photoelectric conversion element that conducts optical/electrical and electrical/optical signal conversion, and an actuation device that drives said photoelectric conversion element, and a receptacle connector mated with said plug connector, with the plug connector and the receptacle connector being electrically connected through mutual contact between terminals, wherein, in the plug connector, the front end side of a fiber optic cable used for optical signal transmission is connected to the rear end side of said plug connector and extends from the rear, lateral terminals are arranged in each of a pair of lateral edge portions that extend in the forward-backward direction, while end terminals are arranged in a front end edge portion 34 that extends perpendicular to the forward-backward direction.
