Performance characteristics of wire spring sockets:
为了满足电流大、寿命长、温升低、插拔力小的研制技术协议要求,必须对接触偶的结构形式进行优选。根据我厂多年来生产高可靠线簧结构电连接器的经验,决定选用高可靠单叶回转双曲面线簧插孔(简称线簧孔)作为该连接器的接触偶。 线簧孔是一种结构新颖、性能优异、可靠性高的插孔,与开口插孔、片簧式插孔相比,具有接触电阻小、插拔柔和、抗振动、耐冲击、寿命长、可靠性高等特点,其失效率仅 为10-9 。因此,从结构及性能特性上分析,选择线簧孔作为该电连接器的接触偶是比较佳的方案。
In order to meet the requirements of the technical agreement for the development of high current, long life, low temperature rise and low insertion force, it is necessary to optimize the structure of the contact couple. Based on the experience of producing high reliable linear spring connector in our factory for many years, we decided to choose the high reliable single leaf rotary hyperboloid linear spring jack (referred to as linear spring hole) as the contact couple of the connector. Wire spring hole is a kind of jack with novel structure, excellent performance and high reliability. Compared with open Jack and leaf spring jack, it has the characteristics of small contact resistance, soft insertion, vibration resistance, impact resistance, long life and high reliability. Its failure rate is only 10-9. Therefore, from the analysis of structure and performance characteristics, it is the best scheme to select the wire spring hole as the contact couple of the electrical connector.
Assembly Technology and Requirements for Line Spring Sockets:
Wire spring jack is a high reliable Jack assembly, which is the contact part of electrical connector. Jingcheng industry has a professional technology. It uses special assembly technology. It is made of several beryllium bronze wires with high elasticity (hereinafter referred to as copper wires) which are diagonally drawn and compacted along the inner wall of the jack. All copper wires form a specific angle with the inner wall of the jack, so that all copper wires in the jack are in hyperbolic shape (such as the left picture). This is the case. Therefore, the line spring jack is also called the hyperboloid line spring jack. When the pin is inserted into the wire spring socket, all the copper wires are close to the outside surface of the pin in a larger range. At this time, all copper wires in the pin are in multi-line contact with the pin (such as the right figure). Therefore, the advantages of the structure are small contact resistance, small heat generation, high reliability of connection, soft insertion force, good vibration resistance and impact resistance. The advantages of high strength, multiple insertion times, long service life, and less than 1uS instantaneous break time in high vibration and shock resistant situations have been fully verified in various application fields.
