An electrical contact for mating with a mating contact includes an aluminum body extending along a longitudinal axis and formed of an aluminum or an aluminum alloy, a contact zone disposed on a surface of the aluminum body and adapted to be electrically connected to a mating contact, and a contact spring connected to the aluminum body and having a contact region contacting the mating contact. The aluminum body has a connecting portion adapted to be connected to an aluminum conductor. The contact zone is formed from a material that is more creep-resistant than the aluminum body. The contact spring at least partially rests on the contact zone and is formed from a material that is harder than the aluminum body.

An electrical connector assembly for electrically and mechanically connecting a component to a power source is disclosed. The connector assembly includes a male terminal with side walls defining a receiver. The side wall includes a contact arm that extends across an aperture in the side wall. The assembly also includes an internal spring member dimensioned to reside within the receiver of the male terminal. The spring member has at least one spring arm that extends from a base portion. The assembly further includes a female terminal with a receptacle dimensioned to receive both the male terminal and the spring member residing within the receiver of the male connector to define a connected position. In the connected position, the spring arm exerts an outwardly directed biasing force on the contact arm of the male terminal to outwardly displace it into engagement with an inner surface of the receptacle to ensure connectivity.

An electrical connector system for electrically and mechanically connecting with a component in a motor vehicle is disclosed. The connector system includes a motor vehicle component and a male connector assembly with a male housing that receives a male terminal. This terminal includes a receiver and side walls with a contact arm that extends across an aperture in the side wall. An internal spring member with at least one spring arm resides within the male terminal receiver. A female connector assembly includes a female terminal with a receptacle that receives both the male terminal and the spring member. A female housing receives the female terminal and an extent of the male connector assembly. When the connector system moves from the partially assembled state to a connected position for connection of the vehicle component, the male connector assembly is inserted into female housing, the contact arm is brought into sliding engagement with an angled internal segment of the female housing, and the contact arm is inwardly displaced as the contact arm slidingly engages with the angled internal segment.

A high-performance single barrel power connector for receiving electric power may be capable of receiving more than 330 W up to approximately 600 W of power. The V+ pin and V− pin may each be configured with a large plurality of contact points for connecting to a power plug. A connector body retaining the V+ pin and V− pin may configured with openings to expose more of the V+ pin and V− pin to air and allow the V+ pin and V− pin to extend out of the power connector for convective and conductive heat transfer. A shell having a high thermal conductivity may be connected to the V− pin and V− pin and further connected to a bracket for increased heat transfer away from the V+ and V− pins.

A terminal-equipped electric wire includes a terminal to be electrically connected to a connection target member, and an electric wire to be connected to the terminal by ultrasonic joining. The terminal includes a joint portion to be connected to the electric wire, a connection portion to be connected to the connection target member, and a plating layer on a surface of the terminal. The connection portion has an uneven shape on at least a part of a surface thereof. When the terminal-equipped electric wire is connected to the connection target member, an insulating coating of the plating layer covering at least a part of the surface of the connection portion is broken.

The present invention relates to a test socket having a thin structure that can reduce durability degradation of a contact itself, have excellent electrical characteristics in processing high-speed signals, and can extend a service life thereof, and relates to spring contacts suitable thereto. The test socket according to the present invention includes: a plurality of spring contacts (100) each of which includes an upper contact pin (110) and a lower contact pin (120) that are assembled cross each other, and a spring (130) supporting the upper and lower contact pins (110 and 120); a main plate (1110) having a plurality of accommodating holes (1111) in which the respective spring contacts (100) are accommodated, with first openings (1113); and a film plate (1120) provided on a lower portion of the main plate (1110), and having second openings (1121).
