How to identify the connector’s high current and low current.

How to identify the connector’s high current and low current? High current and low current is a relative concept when used. There are many differences according to  the use of different objects or different methods . How to clearly divide the currents? Now, let RENHOTEC‘s engineers give you a detailed introduction.

In general, the magnitude of the current is relative, if you want to determine the size of the current,then must start from its basic verification of the amount of electricity. Normally the rated current loop is rated , it will be a large current if it exceeds this rating . For example, if the charger’s current is 500mA, it is a small current in our eyes, but it is a large current when used on a charger .

Of course, the size of the current is related to the thickness of conductor. The current of the power supply reaches the load through the connector, the contact resistance between the pin and the socket, and the resistance of the pin and the socket itself, which together constitute the additional resistance of the circuit. And the load resistance is in series relationship. When the circuit current is large and the pin is small, the energy consumed by the additional resistor will cause the contact point to heat up. If the time is long, the pins and sockets will be oxidized and deteriorated, causing poor contact and entering a vicious circle until Broken circuit.

All in all, as long as the current is more than the planned current is a large current, if using the 500mA in the induction cooker, then the current should be a small current. Let’s take a look at the charger. At present, most of the currents we use are lithium-ion batteries, It can use a small current to charge, and also can use a large current , its speed much faster when using a large current.

It can be seen that the large current and the small current have no difference in the data, there will be some real explanations when there is a comparison, the reaction will be more obvious on the used object or on the limited value of the correlation.
