How to choose the right connector?

A connector is a component that we electronic engineers and technicians often come into contact with. It establishes a communication bridge between blocked circuits or blocked circuits in an electric circuit, so that the current can flow and the circuit can realize the intended function. Connectors are important components in electronic equipment. If you follow the path of current flow, you will always find one or more connectors. So, how to choose a suitable military circular electrical connector? We can consider the following relevant aspects:1. What the connector type connects to, where it is used and so on. Is the problem to be considered, it determines the type of connector to be selected. Connector use place (indoor, outdoor, corrosive environments, etc.). Will affect whether to enhance the airtightness of the aviation plug or in the insulator outside the shielding shell. The type of connector determines which terminals are used and how many conductive terminals are arranged. Of course, it also involves some of the technical reference of the terminal. 2. Electrical Requirements When choosing a military circular electrical connector, consider the electrical requirements of the product. What kind of voltage and current requirements of the product, whether the connector can be well suited to such electrical characteristics? These electrical requirements need to be considered. In addition, we also need to consider some other electrical conditions: resistance, the amount of permissible resistance change, millivolt drop, current value, voltage value, inrush current value, characteristic impedance, VSWR (Voltage Standing Wave Ratio), insertion and removal loss, EMI shielding efficiency.3. Environmental requirements temperature, humidity and other environmental conditions are determined by the location of the electrical connector, so consider the location and the expected environment. As well as other relevant storage conditions applicable period and information. The description of the environment should also cover the requirements for shock and vibration, including maritime transportation, and the requirements of the production environmental conditions, such as soldering temperature and duration of the soldering cycle. Used in the military circular electrical connectors for the manufacturer that the area around the converging continuous current guided by the connector is the temperature generating region.4. Mechanical performance requirements What kind of volume and coverage area is useful for the connector; what are the allowable dimensional tolerances; what is the insertion and extraction force of the terminals; what is the usability of the connector (insertion and extraction frequency)? All of these factors are considered when selecting an electrical connector. As an example, for printed circuit boards, it is important to determine the tolerance of the printed circuit board, which is the critical value of the card-edge connector, and the feasibility of reaching the critical value. For low power circuits, the coating and underlay material should meet signal criteria and environmental ratings.5. Specification Manufacturers of military circular electrical connectors can use approximately 25 testing organizations (developed specifications) as a source for their connector test specifications. Consider the appropriate test specification for the specific application, including general. There is much more to how to choose a suitable military circular electrical connector. The above are just some of the factors in a broad sense and not all are covered.
