Five factors to be considered in choosing circular connectors

The operation of a circular connector will affect the function of the whole equipment. Proper circular connector can bring twice the result with half the effort. So, how to choose a suitable electric circular connector? We can consider the following related aspects: I.Types of circular connectors These questions, such as what to connect and where to use them, should be considered first, which determines the type of industrial circular connector selected. The location where the circular connector is used (indoor, outdoor, corrosive environment, etc.) will affect whether to enhance the sealing of the aviation plug or to add a shelter to the insulation body. The type of circular connector determines which terminal to use and how many conductive terminals to arrange. Of course, it also involves some reference of terminal technology. II. Mechanical Performan For circular connectors, what kind of volume and footprint is effective; what size tolerances are allowed; what is the insertion and pull-out force of terminals; and how is the durability of circular connectors (the frequency of insertion and pull-out fit)? These factors should be considered when choosing circular connectors. For example, for PCB, it is very important to determine the tolerance of PCB. It is the critical value of card edge connection and the feasibility of achieving the critical value. For low power circuits, plating and underlying materials must be specified in accordance with the signal standard and environmental grade. III.Specifications Aviation plug manufacturers can use about 25 test institutions (specifications) as the source of all or part of the test specifications for their circular connectors. Consideration must be given to the use of appropriate test specifications in specific application situations, including those commonly used internationally. IV. Electricity Requirements When choosing the circular connector for aviation, the electrical requirement of the product should be considered. What are the voltage and current requirements of the product, and whether circular connectors can be well applied to such electrical properties, these questions about electrical requirements need to be considered. In addition, we also need to consider some other electrical conditions: resistance, allowable resistance variation, millivolt drop, maximum current, maximum voltage, inrush current, characteristic impedance, VSWR, insertion loss and EMI masking efficiency. V. Environmental requirements Temperature, humidity and other environmental conditions are determined by the location of the aviation connector, so the location and expected environment should be considered. What is the shelf life of other relevant storage conditions and information? The description of the environment should also cover requirements for shock and vibration, including those arising from maritime transport, as well as production conditions such as welding temperature and duration of welding cycle. The manufacturer of circular connectors says that the area around the convergent continuous current guided by circular connectors is the area where the highest temperature is generated. How to choose a suitable electric circular connector is far more important than these. The above contents are only a few factors in a broad sense and not all of them are covered. When choosing electric circular connectors, it is important to choose a good product company.
