high precision connectors

　　In recent years, as the volume of digital products becomes smaller and smaller, the precision and space requirements for connectors are also getting higher and higher, which promotes the continuous growth of the market share of pogopin connectors. At the same time, new pogopin connector manufacturers have been emerging in recent years, and the competition in the domestic pogopin connector market is very fierce. It is true that there is competition and opportunity. As a veteran of the connector industry for 17 years, Chen Minqiang founded the thimble connector (hereinafter referred to as "thimble") in 2017, focusing on creating "1A-20A high current" pogopin connectors, becoming a rookie in the connector industry.

　　It is reported that the plant area of the thimble is more than 1,700 square meters, equipped with dust-free workshops and automation equipment, and its automatic riveting technology and semi-automatic riveting technology and high-quality raw materials selected from South Korea, Japan, Taiwan and other places are supported to ensure that cutting- The whole process of grinding-secondary processing-grinding-extrusion-electroplating-extrusion processing-cold forming-sealing-assembly molding is successfully implemented.

　　It is worth mentioning that in the past two years, driven by the thinning of smartphones and the rise of smart wear, the demand for high-current connectors and magnetic data cables has increased, making the application of pogopin connectors more frequent. Most of the smart digital products on the market use pogopin connectors.

　　One of the components of these smart wearable devices is the pogo pin connector, which is also called: pogopin connector, thimble connector, charging pogo pin, and signal pin. This connector consists of three parts, namely spring, pin head And the needle tube, these three parts are indispensable. The second component is the swipe data cable: the plug-in charging port before optimization, the swoosh quickly charges the suction, and can be quickly pulled away without any damage, and has the functions of charging, transmission, and signal.

　　In addition to understanding the basic structure of the pogopin connector, the current requirements, impedance, life, stability, and the way the product is assembled have different performance requirements for the pogopin.

　　In order to ensure that the needle keeps in contact with the needle tube during operation, the thimble design the end of the needle in contact with the spring into a beveled structure. Mr. Chen said: "This design concept can ensure stable contact resistance and stable conduction of products."

　　At the same time, the thimble implements refined management, including IQC incoming inspection, IPQC process inspection, elastic force and resistance dynamic test, full appearance inspection, FQC sampling inspection, OQC shipment inspection, design verification and regular reliability inspection, failure analysis and so on. Strict and effective quality control is carried out in all aspects of product design, sample preparation, trial production and mass production, thus ensuring the quality of products.

　　At present, the thimble has its own strong technical ability to apply in terms of size control of connectors, selection of electroplating materials, spring design, impedance testing, etc. Structural engineering is interested in its excellent space saving ability due to its ultra-short and ultra-small size in design, coupled with the conductivity, high-frequency characteristics and extremely low on-resistance of our connectors due to electroplating process, In addition, the design of the spring in the connector ensures stable elastic force and life stability of hundreds of thousands of times.

　　According to the author's understanding, the current thimble factory is equipped with multiple precision lathe machines, providing customers with single/double row and long and short pogopin customization. The material can be customized to meet the national standard environmental protection copper and lead-free copper, and the rubber core (plastic) is ROHS halogen-free. Environmental requirements. With the advantage of high energy output, in the field of smartphones and smart watches, thimble connectors have entered the supply chain of Huawei, Gionee, Xiaomi, etc.; in the field of drones, it has cooperated with DJI.
