The present disclosure discloses an electric connection assembly having a support and a connector; the support comprises a support body; the support body is provided with a mounting groove and a limiting protrusion; at least part of the connector is arranged within the mounting groove; and the limiting protrusion can cooperate with the connector so as to prevent the connector from withdrawing from the mounting groove. Compared with the prior art, the electric connection assembly is simple in overall structure and convenient to assemble. In the electric connection assembly, the stability of the integral assembly of the connector and the support can be enhanced by arranging the corresponding limiting protrusions on the support. Particularly, compared with the support and the connector which are integrally formed by embedded injection molding, the electric connection assembly can avoid the problems of fixed mounting position, inflexibility and the like of the connector due to reasons such as tolerance and the like.

Provided is a housing including a bottom wall, a front-end wall, side walls, and a mating space. Each of the side walls includes a locking protrusion configured to engage with a counterpart locking protrusion locking protrusion of a counterpart housing when the counterpart housing is inserted into the mating space. Each of the side walls also includes an auxiliary-metal-fixture mounting portion configured to be loaded with an auxiliary metal fixture having a bottom end that is to be fixed to a surface of a board. The terminal is configured to be loaded in the front-end wall, and includes a connection part having a bottom end that is to be fixed to the surface of the board. The bottom wall has a surface facing the surface of the board, slanted surfaces are formed respectively on the left side edge and the right side edge of the surface of the bottom wall so that each slanted surface extends, in the front-to-rear direction of the sidewall, towards the outer side of the housing with a gradually widening gap with the surface of the board.

An electrical connector having a barrel or hollow cylindrical sleeve into which is inserted a cylindrical interface member adapted to accept a coil spring member on one end thereof. The interface member on its other end acts upon a cylindrical sphere or ball captured with the other end of the sleeve member. The ball is movable axially and rotationally within the sleeve to make electrical and mechanical contact with an external surface which may be either movable with respect to the ball or not perpendicular to the ball. The connector is formed to direct current to pass primarily through the sleeve and to bypass the spring.

A board connector including plural terminal units each including an inner terminal, an outer terminal covering the inner terminal, and a terminal unit-side dielectric body provided between the inner terminal and the outer terminal and supporting the inner terminal. The plural terminal units are arranged in a row along one direction in a state in which adjacent of the plural terminal units contact each other.

A board connector including an inner terminal including a connection portion for connecting to an inner conductor, an outer terminal, and a terminal unit-side dielectric body. The outer terminal includes a terminal-side covering portion covering the inner terminal in a state in which the connection portion protrudes outward, and a terminal-side extension portion extending from the terminal-side covering portion and extending alongside the connection portion. The terminal unit-side dielectric body is provided between the inner terminal and the outer terminal at an inside of the terminal-side covering portion so as to support the inner terminal.
