An electrical connector includes a housing and a terminal module mounted in the housing. The terminal module includes an insulative body, a fixed part mounted on the insulative body extending along a back-to-front direction, and a plurality of terminals. The fixed part defines a mounting hole through the fixed part along front-to-back direction. The insulative body has a connecting arm inserting into the mounting hole for position the fixed part on the insulative body. The fixed part defines a pilot hole extending to the mounting hole, and glue is disposed into the pilot hole to bond the fixed part with the insulative body.

An electrical connector includes contact pins, insulating housings for containing the contact pins therein and metallic outer contacts for respectively covering the housings. Each of the contact pins includes a horizontally extending portion, a contact portion, a connection portion, a downwardly extending portion and a press-fitting shoulder extending from a side portion of a base end portion of the horizontally extending portion in a width direction thereof. A width of the press-fitting shoulder of each of the contact pins decreases from a base side toward a tip side.

A circuit board with circuit components mounted thereon is integrally molded with a sealing resin having a sealed end face part that is a thermosetting resin. A cylindrical intermediate adapter is bonded and fixed to the sealed end face part with an opening into which a receptacle body of a connector housing is inserted. A resilient contact connected to a lead wire is caused to be in electrical contact with a copper foil trace terminal of the circuit board. The connector housing and the intermediate adapter are made of a thermoplastic resin resistant to crack failure, which improves handling capability for inserting and withdrawing a connector.

A coaxial connector assembly for interconnection with a coaxial cable with a solid outer conductor is provided with a monolithic connector body with a bore. A mating surface with a decreasing diameter toward a connector end is provided on an outer diameter of the connector body proximate the connector end. An overbody may be provided overmolded upon a cable end of the connector body. An interface end may be seated upon the mating surface, the interface end provided with a desired connection interface. The interface end may be permanently coupled to the mating surface by a molecular bond interconnection. In a method of interconnection, the interface end is coupled to the mating surface by application of radial ultrasonic welding.
