What to consider in custom pogo pin connector

  The operation of a pogo pin connector will affect the function of the entire device, suitable for a pogo pin connector can bring twice the result with half the effort. So, how to choose a suitable pogo pin connector?

What to consider in custom pogo pin connector(图1)

  The first point: the specifications of the pogo pin connector

  Connector manufacturers can choose to use about 25 testing institutions (specified specifications) as the source of all or part of their connector test specifications. We must consider the selection of appropriate test specifications for specific use cases, including internationally common conditions.

  The second point: pogo pin connector type

  What equipment is connected, where is the application, and other issues need to be considered first, which will determine the type of pogo pin connector selected. The location where the connector is used will affect whether to enhance the airtightness of the aviation plug or add a shielding shell outside the insulating body. The type of pogo pin connector determines which terminal to use and how many conductive terminals to arrange. Of course, this will also be related to some terminal technical references.

  The third point: the mechanical performance requirements of the pogo pin connector

  For the pogo pin connector, what is the effective size and coverage area; what is the allowable dimensional tolerance; how much is the insertion and withdrawal force of the terminal; what is the durability of the connector (the frequency of mating and mating); these All factors must be considered when choosing a connector. For example: for printed circuit boards, it is very important to confirm the tolerance of the circuit board. It is the critical value of the card edge connector and the feasibility of reaching the critical value. For low-power circuits, the plating and underlying materials must be specified and the signal standards and environmental levels must be the same.

  The fourth point is the electrical requirements of the pogo pin connector

  When choosing a pogo pin connector, you must consider the electrical requirements of the product. What are the voltage and current requirements of the product, and whether the pogo pin connector can be used in such electrical properties? These issues related to electrical requirements need to be considered. In addition, other electrical conditions should be considered: resistance, allowable resistance change, millivolt drop, maximum current value, maximum voltage value, inrush current value, characteristic impedance, VSWR (voltage standing wave ratio), insertion loss And EMI shielding efficiency.

  Fifth point: Environmental requirements of pogo pin connector

  Temperature, humidity and other environmental conditions are mainly determined by the location of the pogo pin connector, so consider the location and the expected environment. What is the applicable period of other relevant storage conditions? The description of the environment should also include requirements for shock and vibration, including requirements from shipping, as well as requirements for production environment conditions such as welding temperature and welding cycle duration. The connector manufacturer says that the area where the highest temperature occurs is around the combined continuous current that the connector leads.
