簧中簧电子有限公司（SiS）成立于2007年10月，专业从事弹性导电电子元器件的设计、测试、制造的公司。
    Spring in Spring Electronics Co., Ltd. (SiS), founded in October 2007, specializes in the design of the elastic conductive electronic components, testing, manufacturing company.


    基于连接器行业对大电流及电流连续性中断的要求越来越高，簧中簧电子研发了新型的斜形椭圆双向螺旋弹簧触指，斜形椭圆双向螺旋弹簧触指构成多个列式形变接触点，填补了国内外对大电流连接器高使用寿命、低温升、低电流中断时间和低成本的空白。接触处弹簧触指横切面积接近于电缆横切面积，有效可靠地传递大电流，可达多触点接触达到低温升，同时杜绝电流中断时间；弹簧触指的斜向变形，低插拔力；高使用寿命，可达10万次。
    Connector industry is increasingly high demand for high-current and current discontinuity, SiS has developed a new type of Canted oval bi-directional spiral spring finger, R & D Canted-oval bi-directional spiral spring finger to constitute more than one column deformation point of contact. To fill the blank of domestic and foreign connectors for high current high life, low temperature rise, low-current interruption time and low-cost. Contacts at the spring finge the cross-sectional area is close to the cable cross-sectional area, effective and reliable transmission of high current, up to multi-touch access to low temperature rise, at the same time put an end to the current interrupt time; Canted deformation of the spring finger, low insertion force ; high durability, up to 100,000 times.

   SiS电源接线端子高电流承载能力和高使用寿命，广泛应用于大电流传输电气设备，电动交通工具，例如：电动汽车、充电基站、风能发电机、电源供应器。
   SiS power terminal high current carrying capacity and high service life, widely used in high-current transmission and electrical equipment, electric vehicles, such as: electric vehicles, charging base station, wind generators, power supply.

    公司拥有自主知识产权，国家多项专利，产品通过国际多项严格标准测试。
     The company has independent intellectual property rights of national patents, the products have passed the stringent standards of the international number of tests.
