The wire spring jack uses a small trick
The wire spring hole structure is a high-stability and high-reliability contact couple in high-current terminal blocks and connector products.
What is a wire spring hole? (Copper wire is generally used), which is bent by several wires around the inner sleeve, and then pressed into the front and rear ends by the two jackets and fastened into one. Since the wire is diagonally intersected with the axis of the inner sleeve at an angle, a single-page hyperboloid structure is formed, and a throat circle is formed, the diameter of which is smaller than the aperture formed at both ends. When the pin is inserted, the pin is contained by each wire, because each wire is in contact with the pin and is subjected to tension, so the electrical connection contact is reliable and the force is uniform.
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 increasingly high requirements of the connector industry for high-current connectors, spring in the spring electronics has developed a new type of bidirectional coil spring finger (SiS®), single-turn spring finger, Constitute multiple columnar deformation contact points (up to 300 points or more). 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.
