A surface mount electrical connector and methods of making and using a surface mount electrical connector. The connector includes a housing and a contact subassembly received in the housing. The contact subassembly includes interface contacts, board termination contacts, and an internal circuit board. The interface contacts and the board termination contacts are mounted to the internal circuit board to electrically connect the interface contacts and the board termination contacts through the internal circuit board. Each of surface mount tail ends of the board termination contacts has a bent portion that defines a mounting surface configured to be surface mounted to a mounting face of a main circuit board, to establish an electrical connection between the board termination contacts and the main circuit board.

An electric connection socket for relaying electric signals between a circuit substrate and an electric component includes: a metal housing which has a through hole enabling communication between the top surface and the bottom surface thereof, and on the top surface of which the electric component is mounted and on the bottom surface of which the circuit substrate is mounted; and a signal pin inserted into the through hole to configure a coaxial line between the inner wall surfaces of the through hole, and which is electrically connected at one end to a signal path first pad electrode of the circuit substrate and is electrically connected at the other end to a signal path terminal of the electric component. On the bottom surface, the metal housing has a ground connection unit which contacts a second pad electrode for grounding formed on the circuit substrate and which grounds the metal housing.

A connector is disposed on a board in a first direction and includes a housing, a contact, and a movable. The housing is provided with a bottom surface facing the board and a through hole formed along the first direction. The contact is held in the through hole and has its end portion on a board side exposed at the bottom surface via the through hole. The movable terminal is formed as a separate member from the contact, disposed at a close position to the contact in the through hole, and movable in the first direction relative to the contact. One end of the movable terminal in the first direction is fixed to the board and projects from the bottom surface in accordance with movement of the movable terminal, and a projection amount of the one end changes depending on a position of the movable terminal in the first direction.

A circular power connector that can accommodate plugs of varying diameters includes a plurality of electrical terminals that include a contact beam extending from and monolithic with base, where the contact beam includes a contact portion, and a mounting portion that extends from and monolithic with a base for mounting the terminal to a substrate. The terminals are cylindrically arranged to receive a plug. Alternatively, each electrical terminal includes a frame portion, a first contact beam extending from the frame in a first direction, and a second contact beam extending from the frame in a second direction. Multiple electrical terminals are oriented so that the first and second contact beams for one terminal extend at an angle, preferably perpendicular, to the first and second contact beams of another electrical terminal, in a still further embodiment, an electrical terminal having two halves is provided.

An electrical connector comprises an insulating body, a number of conductive terminals, and a metal shielding shell. The insulating body comprises a tongue plate. Each conductive terminal comprises a mating portion exposed to the tongue plate. The metal shielding shell at least partially encloses the tongue plate. The metal shielding shell comprises a receiving space for receiving a mating connector. The electrical connector also comprises a metal fixed shell expanding outwardly. Compared with the prior art, the present disclosure shortens the length of the metal shielding shell. After the metal shielding shell is installed on the device shell, it will not be obviously observed from the outside so as to improve the appearance. Besides, the shielding effect is improved by providing the metal fixed shell supported on the device shell. The present disclosure also discloses an electrical connector assembly having the electrical connector.
