Problems solved by technology

Because the secondary arc is often generated between the gaps between the two electrical connections, it is easy to be ignored by people, but the secondary arc often causes damage to the electrical contacts, resulting in a lower service life of the equipment

Abstract

The invention relates to the electric connection field of a connector, especially to an electric connection method for secondary arc prevention. When two electric connecting terminals are connected, a gap between the two electric connecting terminals is filled with a flowable conducting medium. During the connection process of the two electric connecting terminals, electric contact surfaces of the electric connecting terminals are uneven and many discharging tips are formed; and a kinetic energy difference is generated between the two electric connecting terminals during the connection process. Therefore, the electric contact surfaces are in primary contact, separation of the electric contact surfaces is caused by the impulsive effect; and a secondary arc is generated at the gap caused by separation. However, when the flowable conducting medium is employed, the impulse generated by contact of the two electric connecting terminals can be cushioned and conductivity during separation of the electric contact surfaces can be guaranteed, thereby preventing the secondary arc.

Description

technical field [0001] The invention relates to the field of electrical connection of connectors, in particular to an electrical connection method for preventing secondary arcs. Background technique [0002] Arc is a gas discharge phenomenon, the instantaneous spark generated by the current passing through some insulating medium (such as air). Electrons escape from the contact metal surface due to an electron emission (thermionic emission, field emission or photoemission), and the gas atoms or molecules in the gap will generate electrons and ions due to ionization (impact ionization, photoionization and thermal ionization). In addition, electron or ion bombardment of the emitting surface causes secondary electron emission. When the ion concentration in the gap is high enough, the gap is electrically broken down and an arc is generated. It not only has a great destructive effect on the contacts, but also prolongs the time to disconnect the circuit. [0003] In the process ...
