The spring touches the connector It is used in GCB/GIS (enclosed combination electric) switchgear intermediate sliding contact, dynamic and static contact contact. Select high-performance and high-quality conductive materials. Manufactured by a special process. Suitable for compact electrical contact design of switchgear. Rely on the deformation of the ring spring made of conductive material to provide the contact pressure of the contact point to carry the rated current. Dynamic thermal stable current. Over a wide range of operating deformations, the pressure at the contact points remains almost constant. It can make up for the corresponding grooves, processing differences of conductive rods, roughness errors, etc. by itself. It can greatly reduce labor intensity and production costs. Simple structure, convenient assembly, strong flow ability, cost saving; Small size, multiple contact points, Z small heat accumulation, impact without electric spark, automatic arc extinguishing characteristics; Each coil works independently to straighten large contact tolerances and compensate for surface irregularities, effectively addressing resistance drift; It can maintain good performance in shock, vibration and harsh environments.

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.
