Based on 20 years of connectors work experience and technical accumulation, Qiang(President and Chief engineer of Kelemax) designed a new plug with limited current and anti-arc: X90S connector, which was approved by the State Intellectual Property Office and obtained a patent certificate in June 2023.

The utility model provides a current-limiting and arc-preventing electric connector, which pertains to the technical field of power distribution devices. The plug requires only the same welding angle when welded with the wire, effectively reducing production costs and significantly enhancing both welding and production efficiency. The external wall of the plug is equipped with a non-slip structure, which facilitates a secure grip when holding the socket and plug by hand, achieving a good anti-slip effect. This feature makes usage more convenient and safer.
