Embodiment Construction

[0025] The method of preventing damage due to arcing between electrical contacts according to the present invention can be applied to a circuit in which a pair of terminals are moved relative to each other so that the electrical contacts thereof are disconnected. The method of preventing damage due to arcing between electrical contacts according to the present invention will be verified with reference to FIGS. 1 to 5 .

[0026]In particular, the method for preventing damage due to arcing between electrical contacts according to the present invention is characterized in that, before the electrical contacts are connected to each other, the base material other than fluorine-based oil is used from 70% to 95% by weight. Grease consisting of oil and from 5% to 30% by weight of thickeners and additives, distributed over terminal electrical contacts and their adjacent areas, so that when the electrical contacts are connected to each other and disconnected from each other, said electric...

Abstract

This method for inhibiting damage due to arc between electrical contacts involves the spreading of a grease composed of from 70% by weight to 95% by weight of a base oil and from 5% by weight to 30% by weight of a thickening agent and additives over a pair of electrical contacts in a circuit which causes terminals to move relative to each other so that they are disconnected from each other, whereby damage on the contact area due to arc occurring when the electrical contacts are isolated from each other is inhibited. As the thickening agent there is preferably used an organic bentonite. As the base oil there is preferably sued an ester oil, glycol oil or poly-alpha-olefin. The base oil preferably has a low density to reduce arc energy.

Description

technical field [0001] The present invention relates to a method of preventing damage due to arcing between electrical contacts between electrical contacts in circuit terminals in circuits of electronic equipment such as slide switches, connectors and wire harnesses. An arc is generated between them. Background technique [0002] Today, various devices such as automobiles already include many connectors, wire harnesses or other components integrated therein. There has been a problem that arcs generated between electrical contacts cause terminals and devices to corrode, and thereby reduce the lifetime of electronic parts. Grease to be introduced into slide switches etc. in automobiles, for example, needs to have no adverse effect on devices made of resin materials such as ABS resin, no change in characteristics due to heat generated by arcs or heat of lead wire welding, and not affected by low temperature. [0003] It is known that a grease for sliding contacts has hithert...
