Bow spring contact fingers (bevel coil spring It can transmit strong currents in a small space and can also be used as a purely mechanical connection. There are no restrictions on its use, and it is suitable for use in a variety of static or dynamic medium and high voltage environments. The size of the spring fingers and the independent number of coil turns make the spring suitable for a variety of electrical contact designs, and the Z large contact point is the best current-carrying capacity for electrical or EMI shielding. Each wire circle will independently compensate for contact and surface variations, which allows for a wider range of tolerances between fittings. Multiple contact points increase conductivity, and at the same time its operating temperature is relatively low, so it has a longer service life. Our spring finger technology is used in power contact applications in a variety of industries. Including medical electronics, medical devices, aerospace

and defense, energy and automotive, and so on.

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®) and single-turn spring finger , forming multiple columnar 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.
