Metal contact element and high-voltage electric connector thereof

Abstract

The invention discloses a high-voltage electric connector provided with metal contact elements. The first metal contact element and the second metal contact element are respectively provided with a work contact section and electric arc generating structures generating electric arcs when the two metal contact elements are in contact with each other; when the electric arc generating structure of the first metal contact element is in contact with the electric arc generating structure of the second metal contact element, an electric arc generating zone is formed in a zone where the first metal contact element and the second metal contact element are in contact; the end of the second metal contact element is provided with a second insulator enabling the end of the first metal contact element to be in an uplifting state; an elastic sheet controlling the end of the first metal contact element to reset is arranged on the upper surface of the first metal contact element, and first insulators used for isolating the electric arc generating zone and the work contact zones are arranged on a set of compressed springs on the elastic sheet. According to the structure of the first metal contact element, the second metal contact element and the elastic sheet, when the first metal contact element and the second metal contact element are plugged and pulled, the first insulators and the second insulator are used for controlling generation and isolation of the electric arcs, and therefore the function of arc extinction is achieved.

Description

technical field [0001] The invention belongs to the connector in the communication field or the automobile field, and in particular relates to a metal contact piece for isolating electric arc through an insulator thereon and a high-voltage connector provided with the metal contact piece. Background technique [0002] At present, high-power electrical connectors are mostly realized by low-voltage and high-current, which greatly increases the power loss in the transmission process, and at the same time greatly increases the operating environment temperature. If high voltage and low current are used, when the voltage exceeds a certain value, the contact pairs will generate arcs during the mating and separation processes. The arc actually releases the air ionization phenomenon between the pair (contact pair) under the action of a strong magnetic field (strong electric field), which will generate high temperature and emit strong light, thereby burning the contacts, and causing fi...
