Product features of spring fingers:

◆Strong flow ability

◆Simple structure, multi-point contact, Z small heat accumulation

◆ Impact does not produce electric sparks, with automatic arc extinguishing function

◆ Each coil works independently, which can straighten the large area contact tolerance and compensate for surface irregularities, so as to effectively solve the problem of resistance drift

◆ It can maintain good performance in shock, vibration and harsh environment

◆Operating temperature: -25°C-*105°C

◆Hardness value: HV≥370

Spring touch finger is a new type of electrical connection product, with simple structure, easy installation, strong flow capacity, cost saving and other advantages, widely used in high-voltage switchgear, high-speed rail, petroleum exploration and testing equipment, new energy vehicles and other fields. Dongguan Spring Leaf Electronics Co., Ltd. independently developed and produced spring fingers, after a special molding process, multiple precise heat treatment, can ensure the accuracy and performance of the product,

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.
