the accuracy and performance of spring fingers,

1. Simple structure, small size, less materials, low cost; Meet the requirements of small space and size in device design, suitable for compact design; The small number of components simplifies the design of connector parts

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,

2. Multi-point contact, high concentration, can achieve almost lossless contact. Ensure a large current carrying capacity; Good electrical conductivity, high electrical and thermal stability.

3. The contact pressure of each contact point is not high, and it has good wear resistance.

4. The unique structure makes it have a wide working range; Large tolerances are allowed in the contact surfaces; It has greater adaptability to processing errors and assembly errors, and is more suitable for large-scale production.

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.
