A self-aligning electrical connector system for data and/or energy transmission includes first and second connector parts and a support frame. The first connector part includes positioning pins, flat elements, and a ball socket positioned between the flat elements. The second connector part is attachable to the first connector part and includes positioning chambers engageable with the positioning pins to achieve a coarse positioning of the connector parts relative to one another. The support frame has a flat central bar including spring arms. A ball is supported by the ball socket. The first connector part is supported on the support frame by spring forces of the spring arms acting on the flat elements and is supported on the ball with the ball being rollable on the central bar whereby the first connector part is floatingly arranged on the support frame and is shiftable and tiltable relative to the support frame.

An electrical flat socket contact device includes a contact chamber, a plurality of electrical contact springs arranged in the contact chamber, and a mechanical retaining spring arranged in the contact chamber separately from the electrical contact springs. A tab contact is insertable into the contact chamber. The electrical contact springs electrically contact the tab contact and the mechanical retaining spring mechanically retains the tab contact.

A removable device for retaining electrical contacts, having: a rigid element for holding electrical contacts including a plurality of housings that are configured to accept the electrical contacts, the lateral walls of the holding element that are adjacent to the housings having a plurality of openings that each lead into one housing of the plurality of housings of the holding element; and an elastic element for retaining the electrical contacts in the holding element including a plurality of sprung blades that are arranged facing the openings leading into the housings of the rigid holding element so as to retain the electrical contacts in the housings of the holding element. The invention further relates to a soldering method implementing such a device.

The present disclosure relates to a board connector including a receptacle insulating part, a receptacle transmission contact coupled to the receptacle insulating part and configured to allow electrical connection to a plug connector, and a receptacle radio frequency (RF) contact coupled to the receptacle insulating part so as to be disposed at a position spaced apart from the receptacle transmission contact and configured to allow transmission of a RF signal.

A connector includes a connector body and a terminal attached to the connector body, the connector being fitted with a counterpart connector, the connector body includes a recess being fitted with a counterpart connector body of the counterpart connector and side walls extending in a longitudinal direction of the connector body, the side walls defining both sides of the recess. The terminal includes a plurality of terminals disposed along each of the side walls, and the plurality of terminals disposed along each of the side walls include one high frequency terminal and ground terminals disposed on both sides of the high frequency terminal. In plan view, a straight line connecting high frequency terminals disposed along both the side walls is inclined with respect to a center line of the connector body in a width direction, and a shield plate of the counterpart connector extends along the center line.

A wafer includes a number of conductive terminals and an insulating frame. The conductive terminals include differential signal terminals, a first ground terminal and a second ground terminal. Each conductive terminal includes a connection portion and a contact portion. The connection portions of the differential signal terminals, the first ground terminal and the second ground terminal are located in a first plane. The first ground terminal includes a first torsion portion and the second ground terminal includes a second torsion portion. The contact portion of the first ground terminal and the contact portion of the second ground terminal are both perpendicular to the first plane. This present disclosure can provide better shielding effect, reduce crosstalk and improve the quality of signal transmission. In addition, the present disclosure also relates to a backplane connector having the wafer.
