Do you know the Electrical Performance of Automotive Connectors?

As a Car Phone FAKRA Connector Factory, share with you.

1. Electrical performance: The electrical performance of FAKRA Connector mainly includes: limit current, contact resistance, insulation resistance and electrical strength.

Rated voltage: The maximum working voltage recommended by the manufacturer, which mainly depends on the insulation material used and the distance between the contact pairs. When some components or devices are below their rated voltage, they may not be able to perform their intended functions, and the connector can work normally below the rated voltage.

2. Rated current: The maximum working current recommended by the manufacturer. In the case of lower than the rated current, the connector generally works normally. During the design of the connector, the thermal design of the connector is used to meet the rated current requirements.

a) When current flows through the contact pair, the contact pair will generate heat due to the conductor resistance and contact resistance. When its heating exceeds a certain limit, it will destroy the insulation of the connector and form a contact to soften the surface plating, causing failure.

b) To limit the rated current, in fact, to limit the temperature rise inside the connector not exceeding the design specified value.

c) The problem to be paid attention to when selecting is: For multi-core connectors, the rated current must be derated, which should be paid more attention in the case of high current.

3. Contact resistance: Contact resistance refers to the resistance generated by the two conductors at the contact portion. The contact resistance index of a connector is actually contact-to-resistance, which includes contact resistance and contact-to-conductor resistance.

a) Usually the resistance of the conductor is small, so the contact resistance is called contact resistance in many technical specifications.

b) In the circuit connected to small signals, pay attention to the test conditions of the contact resistance given:

Contact surface will be accompanied by oxide layer, oil or other contaminants, and the surface of the two contacts will generate film resistance. When the thickness of the film layer increases, the resistance increases rapidly, and the film layer becomes a poor conductor.

Membrane breakdown may occur at high voltage or electrical breakdown at high voltage and high current.

4. Insulation resistance: It refers to the resistance value that appears when the voltage is applied to the insulation part of the connector, so that a leakage current is generated in or on the surface of the insulation part.

a) Mainly affected by factors such as insulation materials, temperature, humidity, and fouling.

b) The insulation resistance value provided on the connector samples is generally the index value under standard atmospheric conditions. Under certain environmental conditions, the insulation resistance value will be reduced to an unnecessary degree.
