The introduction of Pogo Pin connectors and the development trend of the industry

　　There are different appearances according to different applications, but as a whole, there is a precision spring structure inside the pogo pin. The surface of the product is generally gold-plated, and the unit price of the product is generally about 5 to 1 yuan.

　　The thimble is energized or turned on, most of which are in contact with the copper wall through the oblique downward direction, and the spring bears a small amount, so the inner wall of the copper sleeve is required to be smooth. If the POGOPIN factory makes a non-beveled surface, but the bottom is flat, most of the current must be conducted through the spring, and the requirements for the spring will be very high. Of course, it is necessary to ensure that the power outage occurs when the current suddenly increases. (This is a little bit of my experience in the actual use process)

　　Pogo pin is a spring-type probe formed by riveting and pre-pressing the three basic components of needle shaft, spring and needle tube through precision instruments. There is a precise spring structure inside. The surface coating of pogo pin is generally gold-plated, which can better improve its anti-corrosion function, mechanical properties, electrical properties, etc. The needle tip has a sharp needle, a grasping needle, a round needle, a knife needle, and the like. Pogo pins are generally used in precision connections in mobile phones, communications, automobiles, medical, aerospace and other electronic products, which can improve the corrosion resistance, stability and durability of these connectors. Since the pogo pin is a very fine probe, it can be used in precision connectors to reduce the weight of the connector and the volume of its appearance, which can make the connector more fine and beautiful.

　　Overview of connector development:

　　.The definition of connector (CONNECTOR): refers to all the connector components and accessories used in electronic signals and power supply. The connector is the bridge of all signals. Its quality not only affects the reliability of current and signal transmission, but also And will affect the quality of the operation of the entire electronic machine

　　.Types of connectors: Electronic connectors can generally be divided into two categories: I/O (Input /Output) and Interconnection, of which the I/O category is used for the connection between computer systems and peripheral devices. Such as mouse, monitor, keyboard, list machine, plotter, and network system for signal transmission. Interconnection is used in the main system and peripheral devices to connect electronic zero-loading and electrical signals between system modules. Related products include integrated circuits Sockets (ZIF series) and board edge connectors (SLOT, DDR, PCI, etc.).

　　1. Connector product design generally has the following process:

　　2. Industry trends or customer demands refer to industry standards or customer standards

　　3. Necessary conditions Technical parameters formulated by industry standards or customer standards.

　　4. Design and analysis Design the product structure against the necessary conditions, use material analysis tools, test tools to calculate and test whether the design can meet the necessary conditions.

　　5. Design prototype and confirmation The establishment of design model and review confirmation, sample production and test confirmation.

　　6. Specification Approval Test the product performance according to the customer's requirements and make a "Specification Approval Letter" and send it to the customer for approval. 7. Production Standardization Work standards formulated before mass production, such as SOP, SIP, BOM
