A first inner housing and a second inner housing are combined to form a combined inner housing, in which the first inner housing having a plurality of mutually independent insertion holes is formed of a first dielectric or an electric conductor, and the second inner housing having a plurality of mutually independent terminal-housing chambers is formed of a second dielectric. Terminals of a twisted-pair cable are inserted and housed one-to-one in the terminal-housing chambers of the combined inner housing. The twist-released sections of sheathed cables of the twisted-pair cable are inserted and housed one-to-one in the insertion holes of the combined inner housing. The combined inner housing is covered with a shield member, and the combined inner housing and the shield member are housed in an outer housing.

Even when a connection board has a large thickness tolerance, a stable connection is achieved by absorbing the tolerance so as to stabilize a contact pressure between the connection board and contacts. In a unit in which electrode groups of a connection board are in pressure contact with elastic contacts formed integrally with an inner housing to connect thereto, the inner housing is provided inside an outer case of a card edge connector through an elastic member to be freely movable forward and backward in a thickness direction of the connection board. The positions of the elastic contacts are adjusted by forward or backward moving the inner housing in accordance with the thickness of the connection board inserted into board insertion slots, so a pressure contact force with the elastic contacts is substantially equalized, irrespective of the size of the thickness of the connection board.

A contact includes a contact unit in contact with a terminal of a circuit board, to establish electric connection; and a barrel unit to contain the contact unit. The contact unit has a first contact point to come into contact with the terminal in an early stage of a relative slide operation in a connection direction when connected to the circuit board, and to be inclined according to the slide operation; a second contact point to swing toward the circuit board according to the inclination of the first contact point, and to be brought into contact with the terminal after a delay from the contact of the first contact point against the terminal; and a contact fulcrum portion. The barrel unit has protrusion support portions to support the contact fulcrum portion. Contact surfaces between the contact fulcrum portion and the protrusion support portions are each a rolled surface.
