Embodiment Construction

[0022] Referring to FIG. 1A , a typical prior art male and female connector pair includes a male contact 100 and a female contact 102 . One of the contacts (referred to here as the female contact 102) is flexible and is under tension by means of a spring 112 so that the shaped region of the contact 102 rides on the male contact when the connectors are mated. 100 on the front end and press against the connecting surface of the male contact 100 . The insulative housings 104, 106 surround the male and female contacts and protect the contacts from environmental hazards. The insulative housings 104, 106 also provide the user with a certain protections. In the prior art example in FIG. 1A , additional insulating structures 108 , 110 are provided adjacent to the outer surfaces of the contacts 100 , 102 to support the contacts 100 , 102 and are the two insulating housings 104 , 110 to be mated. 106 provides a receiving channel. A spring 112 is also included to provide squeeze tensi...

Abstract

A novel connector pair suppresses arcing during connection and disconnection. In one general aspect of the invention, first and second insulating barriers are configured to extend beyond corresponding first and second contacts, the barriers being arranged to cover a leading end of at least one of the contacts, and to engage with each other when the contacts are separated by a small gap, thereby closing off substantially all through-air arcing paths between them. In another general aspect of the invention, at least one electrical contact in a connector pair is a bimetal contact having a transitional segment made from high resistivity metal. The transitional segment is configured to make first and last contact during the initial phases of mating and un-mating, thereby increasing electrical resistance and significantly lowering the electrical current and the energy available for electrical arcing.

Description

technical field [0001] The present invention relates to electrical connectors, and more particularly, to an electrical connector that inhibits arcing under connect or disconnect conditions when current is passed. Background technique [0002] Generally, electrical connectors should not be connected or disconnected while powering up an electrical load. Live arcing between the separated contacts of a field electrical connector poses a risk of fire and burns to the user, and all such arcing tends to reduce the useful life of the connector. [0003] However, due to the fallible nature of human beings, it is still true that electrical connectors may occasionally be inadvertently connected or disconnected when powering up an electrical load. When the current is AC, arcing is rarely a problem because the sinusoidal nature of the AC current will cause the voltage to be zero at some point when the electrical contacts separate, and all arcing will tend to self-extinguish. However, w...
