An interior body includes a spring portion, a movable portion, and a fixing portion, which are integrated together and formed by bending a first metal plate having a high modulus of elasticity. An exterior body is formed by bending a second metal plate having low electric resistance. A movable portion of the interior body includes a contact portion and elastic arms. Each of the elastic arms includes, at its tip portion, an elastically pressing portion elastically pressed against a tubular internal surface of the exterior body.

An interior body is housed in a tubular exterior body. The interior body includes a spring portion, a movable portion, and a fixing portion, which are integrated together. Elastic arms are disposed on the movable portion so as to extend downward. Each elastic arm includes, at a lower end portion, an elastically pressing portion, which is elastically pressed against a tubular internal surface of the exterior body. Since the elastically pressing portion is elastically pressed against the exterior body, electric signals are more likely to flow between the movable portion and the exterior body and more likely to be prevented from leaking to the spring portion.

An electrical connector includes a first set of conductors, a first overmolding in physical contact with a body portion of each of the first set of conductors, a second set of conductors, a second overmolding in physical contact with the body portion of each of the second set of conductors, and a spacer in contact with the first overmolding and the second overmolding. A gap is present between the spacer and at least one of the first set of conductors and a gap between the spacer and at least one of the second set of conductors.

Herein is described a n electrical earthing device formed from a sheet of material and comprising: an earthing device connector portion, for connection of the earthing device to a component to be earthed; and an earth cable connector portion, for connection to an earth cable. A first part of the earth cable connector portion is disposed in relation to a second part of the earth cable connector portion so as to define a clamping mechanism. In use, an earth cable positioned between the first and second parts is retained in position and maintained in electrical contact with the clamping mechanism by resilient biasing between the first and second parts of the clamping mechanism.

The present invention provides a contact member that strikes a balance between low electrical resistance and sliding durability. A contact member of the invention has a metal base and a coating disposed on at least part of the metal base. The coating contains fluorinated oil having a polar group, and metal particles surface-treated with a fluorine-based compound having a polar group.

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.

A method of making an electrical connector which includes an insulative housing having a tongue with two opposite surfaces and plural contacts with contacting portions exposed to the two opposite surfaces of the tongue is characterized by the steps of: forming the plurality of contacts from a single contact carrier to have one group of contacts thereof each with a respective contacting portion connected to a first carrier strip and the other group of contacts thereof each with a respective contacting portion connected to a second carrier strip situated beside the first carrier strip; insert-molding the plurality of contacts with an insulator to form the insulative housing while exposing front ends of the plurality of contacts; and severing the first carrier strip and the second carrier strip from the front ends of the plurality of contacts.
