An electrical coupler has first and second housing halves and first and second contacts retained within the first and second housing halves. Wherein the first housing half is identical to the second housing half and the first contact is identical to the second contact.

An electrical connection device including a first end-fitting secured to a first part of an electrical cable, including a first cylindrical lateral surface coaxial to a first axis and a first end surface forming a first angle with the first axis, a second end-fitting secured to a second part of an electrical cable, including a second cylindrical lateral surface coaxial to a second axis and a second end surface forming a second angle with the second axis equal to the first angle, and a holding system configured to hold the first and second end surfaces pressed against one another. The first and second end-fittings are directly in contact with one another and held in contact via a holding system coaxial to the first and second end-fittings and supported by the latter, which contributes to obtaining a compact device.

A male and female power terminal assembly including a male terminal having a male contact portion including an outer contact surface and an inner surface, and a female terminal having a female contact portion including a sleeve and a finger made of an electrically conductive material. The outer contact surface is electrically connected to an inner surface of the sleeve. Further, the male terminal includes a connecting member made of an electrically conductive material which is placed inside a cylindrical hollow portion of the male terminal, and which interconnects the finger with the inner surface.

An electrical connector includes wafer assemblies coupled to a housing. Each wafer assembly includes a leadframe, a wafer body holding the leadframe, and a ground frame coupled to the wafer body to provide electrical shielding for the leadframe. Each leadframe has signal contacts with mating ends extending from the wafer body for mating with mating signal contacts of a mating electrical connector. The mating ends are twisted 45° to define twisted mating interfaces. Each ground frame has ground shields extending from a ground plate along the mating ends of the signal contacts. The ground shields are twisted 45° relative to the ground plate to define twisted shield zones along the mating ends of the signal contacts.

The disclosure relates to a connection component, a connector, a patch cord and a connector inner shell. The connection component is configured to achieve electric connection and includes two connectors. The two connectors have same butt-joint structures and are in a butt joint through the butt-joint structures, the connectors have locking mechanisms, in a locking state, the locking mechanisms lock the two connectors, and the two connectors may be separated after the locking mechanisms are switched to an unlocking state.

Disclosed is a train coupler connector module for electrically coupling a first rail vehicle to a second rail vehicle, the module including: a fixing block with an inner side able to be mounted on an electrical train coupler; a plurality of contact units arranged side by side in the fixing block, each contact unit having a first end facing the inner side of the fixing block and a second end extending outwards from the fixing block, one of the first and second end being a female contact and the other being a male contact; wherein at least one of the contact units is arranged to be individually removable from the fixing block in a direction outwards from the fixing block.

A connector keying system includes at least one keying device including a flange portion and a keying portion. The flange portion includes a front surface and a back surface. Each of the front surface and the back surface extend substantially parallel to a flange plane. The flange portion further includes a connector aperture extending through the flange portion. The keying portion extends around an aperture perimeter of the connector aperture and projects outward from the flange portion. The keying portion includes and extends between a first key end located at the front surface and a second key end opposite the first key end. The second key end defines a keying perimeter about the connector aperture. The keying portion has a height between the first key end and the second key end and the height is inconsistent between the first key end and the second key end along the keying perimeter.
