Wire spring jack

Wire spring jack, its full name is single-leaf rotary hyperboloid wire spring jack, which is a highly reliable jack component used in electrical connectors (that is, connectors) products. The hole is arranged by multiple elastic gold-plated or silver-plated wires according to the straight busbar of the single-leaf rotary hyperboloid, and forms an angle with the inner sleeve straight busbar. When the pin is inserted into the spring hole, the spring wire is elastically deformed in both the radial and axial directions, and the pin is in simultaneous contact with multiple independent spring wires in the spring hole, forming a plurality of independent current paths. Even if individual spring wires in the jack break, the spring holes can still form an effective current path. When the pins are inserted into the jack, these elastic wires are tightly wrapped around the pins, forming a multi-line contact, and a pair of pinholes is equivalent to several pairs of ordinary pins and holes used in parallel, which greatly improves the contact reliability.

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.
