Standards to Consider When Interconnecting Anderson Power Connectors and Equipment Components
Selecting the right power connector for the application is an important interconnect selection step in connecting device design. Proper power connectors add reliability to interconnected devices, so what criteria should be considered when selecting power connectors and device components for interconnection? The following power connector manufacturers answer for you!
Power connector standards for suitable applications:
1. Rated current
Current rating is the most important criterion when choosing a power connector. It is expressed in amperage per circuit and is a measure of the amount of current that can pass through a mating terminal without a temperature rise of more than 85°F (30°C) at an ambient temperature of 72°F (22°C). This current level is then reduced or adjusted to the number of circuits in a given enclosure due to heat (temperature rise) from adjacent terminals.
2. Connector size or circuit density
With the trend of shrinking device size, power connector size is becoming more and more important in the wire connector selection process. Circuit density is a relative measure of the number of circuits a power connector can hold per square inch. It is relative, using this measure, one can objectively determine the space requirements or dimensions of one connector series versus another.
3. Wire size
Wire size is an important criterion when selecting the proper power connector, especially in applications requiring current ratings close to the maximum ratings of the selected connector family, and applications requiring the mechanical strength of the wire. In both cases, the heavier wire gauge should be selected.
4. Rated working voltage
Most applications are within the 250V rating of standard wire connectors, for example Xinpengbo's CH3.96 wire-to-board connectors provide a 5.0A AC/DC current rating. The rated voltage is 250V AC/DC, both for AC and DC voltage. Higher voltage ratings are usually achieved by fully enclosing the male and female terminals separately in the housing. Those hooded housings and fully isolated contacts also provide protection for the metal terminals during assembly and handling of the wire connector.
5. Housing Lock Type
Selection of the type of positive locking power connector suitable for the application is best determined by the level of stress experienced by the mating power connector. Power connector systems with positive locking require the operator to deactivate the locking device before the connector halves can be separated, whereas passive locking systems will allow the connector halves to disengage by simply separating the two halves with moderate force. In high-vibration applications or when wires or cables are subjected to axial loads, either
By design or by accident, positive locking power connectors should be specified.
6. Strain relief device
Strain reliefs or backshells for power connectors can be the primary standard for the additional safety provided by non-conductive strain relief housings. Strain relief prevents "live" wires from contacting other components or "neutral" conductive members if a terminal or wire moves away from its seated position in the power connector housing due to mechanical overstress.
7. Housing and Terminal Materials and Termination Plating
Materials and plating are often one of the last major decisions. Most power connectors are made of nylon plastic. The flammability rating of this nylon is typically UL94V-2 of 94V-0. A higher 94V-0 rating indicates that nylon will extinguish (in the event of a fire) faster than 94V-2 nylon. A 94V-0 rating does not infer a higher operating temperature rating, but a higher flame resistance. For most applications, 94V-2 material is sufficient.
It is very important to choose a suitable standard power connector. The suitable power connector for the application is determined from standard steps such as connector size, bonding force, wire size, configuration and circuit size, and operating voltage. Reading this article should help you choose a standard-compliant power connector. The above is the standard knowledge that power connector manufacturers need to consider when they introduce the interconnection of power connectors and equipment components. I hope you have more understanding of connector products.
