Use of spring touch in GIS:
Spring tentacles refer to a ring coil spring wound by wire for conduction, usually made of 0.1-2.0mm copper wire, with an oval cross-section. Compared with conductive structures such as plum contacts and surface contacts, spring contact fingers have the following characteristics:
1. Simple structure, small size, low cost.
2. Simple equipment, small assembly workload, no special tools required.
3. The allowable deformation is large, and the processing accuracy required for the contact base and conductor is low.
4. There are many contact points and good conductivity.
5. It is easy to change the structure for different flow rates.
Due to these characteristics, it is widely used in gas-insulated metal-enclosed switchgear (GIS).
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.
