The connector is an indispensable component in electronic equipment. Its function is to bridge the communication between circuits that are blocked or isolated in the circuit, so that current can flow and the circuit achieves its intended function. Look down the path of the current and you will always find one or more connectors.
The form and structure of the connector is varied, depending on the application object, frequency, power, application environment, etc., the connector form is also varied. For example, a connector for automotive headlights and a connector for hard disk drives. A hard disk drive and a connector for ignition rockets. But no matter what kind of connector, it is necessary to ensure the smooth, continuous and reliable flow of current.
I. What is the load capacity of the connector?
Connector current-carrying capacity refers to the connector in the case of not exceeding its maximum temperature rating can carry the maximum amount of current, usually including the conductive temperature rise and ambient temperature.
As you can see, temperature is an important factor that affects the current carrying capacity of the connector. The better the heat dissipation, the better the consistency of the internal temperature of the connector, the lower the temperature at the maximum temperature point, the higher the current load that the connector can withstand. Moreover, if the temperature of the connector is too high, it will affect the reliability of the connector and reduce its service life.
In addition to this, there are several other factors that can limit the load capacity of a connector in most applications, including.
2, the electrical conductivity of contact materials.
1、Connector contact cross-sectional area and contact length
2, in many cases, the contact point is the main source of heat generated by the connector.
3, if the contact point is larger, it can provide better heat dissipation and help the connector’s current-carrying capacity
4、Ambient temperature
5、Shell material and structure
