The wire spring jack is a highly reliable pin jack assembly that is an electrical connector in the contact part. Lida Electric has professional technology, it is the use of special assembly technology, a number of highly elastic beryllium bronze wires along the inner wall of the jack diagonally drawn tightly wound, all copper wires and the inner wall of the jack to form a specific angle, so that all the copper wires inside the jack appear hyperbolic shape. Therefore, the wire spring jack is also called a hyperboloid wire spring jack

Wire spring jack when the pin is inserted, all copper wires in a large range close to the outer surface of the pin, at this time all copper wires in the jack and the pin to form multi-wire contact, so the advantages of the structure are small contact resistance, small heat generation, high and reliable connection, soft plugging force, good vibration resistance, strong impact resistance, many plugging and unplugging times, long service life, and in high vibration, impact resistance occasions its instantaneous time is less than 1us, these advantages have been fully verified in various application fields

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 in the Spring Electronics has developed a new type of bidirectional coil spring contact finger (SiS®) and single-turn spring contact finger, which constitute multiple columnar deformation contact points (up to 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.
