Problems solved by technology

Higher power power transmission is the development trend of the industry. Only by increasing the current can no longer meet the actual needs. In the future, more and more power transmission methods with high voltage and high current will be used.
However, if high voltage and high current are used, the contact pair will generate a strong arc during the mating and separation process

Abstract

The invention discloses a high-voltage electrical connector, which comprises a first contact member and a second contact member, wherein the first contact member and the second contact member are bothprovided with a contact region and a combustion region; The second contact part is fixed in the base of the plug, the first contact part is fixed in the socket, and the first contact part is providedwith a spring; Forming a double contact structure between the first contact member and the second contact member; A low-stress nickel layer is electroplated on that contact area, and a noble metal layer is electroplated on the low-stress nickel layer; A low-stress nickel layer, a noble metal layer and a tungsten-nickel alloy layer are sequentially plated on that combustion zone. The surface coating of the connector provided by the invention has good arc ablation resistance, low cost, allows live plug-in and pull-out of large-current silver plating or gold plating connectors, has firm combination between the plating layers, good arc ablation resistance and low cost, and meets the requirements of arc generation prevention and arc burn resistance for live plug-in and pull-out of large-current under large voltage.

Description

technical field [0001] The invention relates to the technical field of high-current connectors, in particular to a high-voltage electrical connector. 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 also greatly increases the operating environment temperature. Higher power transmission is the development trend of the industry. Only by increasing the current can no longer meet the actual demand. In the future, more and more power transmission methods with high voltage and high current will be used. However, if high voltage and high current are used, the contact pairs will generate strong arcs during the mating and separation processes. The arc is actually an ionization phenomenon generated by the gas between the contact pairs under the action of a strong electric field, which will generate high temperature and emit strong ligh...
