Plane contact device used for rapidly conducting large current

Abstract

The invention provides a plane contact device used for rapidly conducting large current. The plane contact device comprises a first conductive base and a second conductive base which are mutually communicated, wherein the conductive surface of the first base is a plane, the base surface of the second base is fixedly provided with an elastic stamping conducting strip, the top end of the elastic stamping conducting strip extrudes out of the surface of the second base, the surface of the second base is provided with a defending surface capable of avoiding the overpressure of the elastic stamping conducting strip, and the defending surface is lower than an elastic extrude surface of the elastic stamping conducting strip. The plane contact device has the main beneficial effects that the current conduction can be ensured all the time with the adoption of the elastic conducting strip when the mutually matched conductive surfaces are contacted, and the current can be favorably conducted without being influenced by vibration environment even when the conductive surfaces vibrate, and thereby, the real surface contact is realized.

Description

technical field [0001] The invention relates to an anti-vibration planar contact device for high current, in particular to a finger-type conductive contact device. Background technique [0002] The normally open and closed current conducting parts generally adopt the plug-in form, that is, the pin socket type, while the existing non-fixed connection form of conduction method adopts the surface contact type, that is, the two planes are closely bonded by a certain pressure. In order to achieve conduction, fixed current conduction can use bolts and screws to compress the contact surface, or apply extrusion force behind one or two conductive surfaces to keep them in contact, such as using a spring to conduct current . Although such a connection is convenient and quick, there are still many disadvantages. Since the conductive plane is pressed by the spring to achieve a relatively fixed contact, in a vibrating environment, the contact plane is subjected to constant vibration, wh...

Although such a connection is convenient and quick, there are still many disadvantages

Since the conductive plane is pressed by the spring to achieve a relatively fixed contact, in a vibrating environment, the contact plane is subjected to constant vibration, which makes the connection stability worse, and often occurs instantaneous disconnection, or power failure and flickering due to the reduction of the contact surface. , high temperature rise and other problems; in addition, due to multiple opening and closing contacts on the flat contact surface, it is easy to attach dust to the contact surface when used in an open space, resulting in poor contact electrical connection
