Abstract: An electrical connector 10 disposed on a circuit board 1 covered by an electrically conductive cover 70, the connector comprising an electrically conductive tubular outer conductor 11 mounted on the circuit board 1 and extending axially along the direction of mating Z with a counterpart electrical connector 20, 40, and an electrically conductive supporting portion 14 provided in the outer conductor 11 and having a connection portion at the top in the direction of mating Z, wherein the connection portion of the supporting portion 14 and the cover 70 are brought into direct or indirect contact when the circuit board 1 is covered by the cover 70, thereby electrically connecting the electrical connector 10 and the cover 70.

Abstract: Herein is an electrical connector with an inner conductor extending in the mating direction, a main body portion extending in the mating direction to accommodate one end of the inner conductor and to which a coaxial cable is attached, and a mating portion extending in the mating direction to accommodate the other end of the inner conductor and mates with a counterpart connector. An accommodating space in the main body portion accommodates one end of the inner conductor. An attachment aperture communicates with the accommodating space by extending in the lateral direction perpendicular to the mating direction and attaches the coaxial cable to the main body portion to connect its center conductor to one end of the inner conductor. The attachment aperture of the main body portion includes a tapered portion decreasing in diameter toward the accommodating space at the end proximal to the accommodating space.

Abstract: To provide an electrical connector assembly capable of reliably restricting the tilting of an adaptor connected to a connector to a predetermined angle or less, an electrical connector assembly includes a first connector, an adaptor, a tubular portion forming part of the adaptor with a supporting portion made of a rigid material, a plurality of resilient pieces, and engagement portions protruding radially outwardly from the distal end portions of the resilient pieces. The first connector involves a main body portion having an opening the main body portion has a peripheral wall forming a recess portion; and, when the adaptor is tilted a predetermined angle relative to the first connector while the adaptor is engaged in a mated state, the supporting portion restricts further tilting of the adaptor by abutting the peripheral wall.
