　　The basic performance of spring pin connector is analyzed

　　1、 Basic performance

　　The basic performance of connector includes mechanical performance, electrical performance and environmental performance.

　　2、 Mechanical properties

　　Mechanical properties as far as the connection function is concerned, the insertion and extraction force is an important mechanical property. The pulling force is divided into insertion force and pull-out force (pull-out force is also called separation force), and the requirements are different. The maximum insertion force and minimum separation force are specified in relevant standards. When the insertion force is determined by the angle of use, the insertion force should be small (thus the structure with low insertion force LIF and non insertion force ZIF). If the separation force is too small, the reliability of contact will be affected.

　　Another important mechanical property is the mechanical life of the connector. Mechanical life is a kind of durability index, which is called mechanical operation in GB 50095. It takes one insertion and one pull-out as a cycle, and takes whether the connector normally completes its connection function (such as contact resistance value) after the specified plug-in cycle. The insertion and extraction force of the connector is related to the mechanical life, contact structure (positive pressure), coating quality (sliding friction coefficient) and contact arrangement dimension accuracy (alignment).

　　3、 Electrical performance

　　Electrical properties mainly include contact resistance, insulation resistance and electrical strength.

　　1. High quality electrical connector should have low and stable contact resistance. The contact resistance of the connector varies from several milliohm to tens of milliohm.

　　2. The insulation resistance is a measure of the insulation performance between the contacts of electrical connectors and between the contacts and the shell. Its order of magnitude is from hundreds of megohm to several Giga ohm.

　　3. The electrical strength is also called withstand voltage and dielectric withstand voltage, which is the ability to withstand rated test voltage between connector contacts or between contacts and enclosure.

　　Shenzhen Witchip Electronics Co., Ltd. was established in 2004 and is located in Longgang District, Shenzhen. It has an independent factory building with an area of approximately 6,800 square meters. Integrating research and development, manufacturing, and sales, it is mainly engaged in the research and development and production of various POGOPIN and POGOPIN connectors, shrapnel terminals, and CNC automatic lathe parts. It can also be produced and processed according to customer samples. There are more than 4000 product categories for customers to choose. The products are widely used in various electronic products such as drones, smart robots, smart wearable products, 5G communication products, smart home products, education/entertainment electronics, medical equipment products, automotive electronics, mobile phone consumer electronics, etc.

　　The company’s R&D and designers are experienced engineering technicians with nearly 20 years of experience in the industry. The total number of employees is 120, with 80 CNC lathes, 100 automatic lathes, 80 assembly equipment, and projectors. Salt spray tester, life tester, current tester, high temperature tester, load dynamic impedance tester. In order to comply with the demand for market quality

　　The company passed the ISO9001 quality system certification in 2007 and successively passed the ISO14001 environmental system certification in 2009. It has 8 independent patents, which provide a solid guarantee for quality and delivery.
