The company specializes in the design, testing and testing of elastic conductive electronic components, and has developed new types of two-way coil spring fingers, single-turn spring fingers, cylindrical rapid plug-in and self-locking fingers Connectors, male and female with the same weight load connector, electric vehicle charger, high-voltage power battery pack series connector, etc.

Dongguan Spring Spring Electronics Co., Ltd. (SiS) was established in October 2011, specializing in the design, testing and manufacturing of elastic conductive electronic components, and moved to Chang'an Town, Dongguan in May 2018. The company has CNC lathe workshop, finger workshop, assembly workshop, laboratory. Based on the increasing requirements of the connector industry for high-current connectors, Spring Springs Electronics has developed a new type of bidirectional coil spring finger (SiS®), single-turn spring fingers, forming multiple column deformation contact points (up to more than 300 points). It can meet the service life of more than 100,000 times, the spring contact current density and temperature rise are close to the transmission cable, and the plugging force is about 10N. PCB board connectors (board-to-board USC, board-to-wire), cylindrical quick-swappable self-locking connectors (plastic and metal shells), male and female weight-load connectors, electric vehicle chargers, high-voltage power battery pack series connectors, used in Z advanced high-current energy collectors, energy storage and electrical equipment, such as: electric vehicles, charging base stations, wind energy generators, power supplies, high-speed rail, heavy trucks, etc. The company has a number of national patents, and the products have passed international standard testing.
