The electrical contact failure of the connector means that the connector cannot ensure sufficient current conduction when it is connected, or cannot ensure sufficient disconnection isolation when it is disconnected. The failure of the electrical contact of the connector may cause the failure or accident of the electrical equipment, so it needs to be found and solved in time.
The reasons for the failure of the electrical contact of the connector may be as follows:
1. Poor design of the connector: Poor design of the connector may lead to poor electrical contact and cannot ensure sufficient current conduction. The reasons for poor connector design may be that the contact area is too small, resulting in excessive resistance; improper contact form, resulting in uneven distribution of current; insufficient contact pressure, resulting in loose contact surfaces, etc.
2. The material of the connector is not suitable: the material of the connector will also affect the quality of the electrical contact. If the selected material has poor conductivity or has defects in itself, it will lead to poor electrical contact.
3. The plugging force of the connector is not suitable: If the plugging force of the connector is too large or too small, it will affect the quality of the electrical contact. If the plugging force is too large, the contact surface will be subjected to excessive pulling force, which will damage the contact surface or even disconnect; if the plugging force is too small, it may cause the contact surface to loosen and cannot ensure sufficient current conduction.
How to ensure that the electrical contact of the connector will not fail?
1. Select the appropriate connector: When selecting a connector, you should choose a connector with reliable quality and good electrical contact performance, and avoid using low-quality or inferior connectors.
2. Pay attention to the use of the connector: Avoid applying excessive insertion force on the connector, and do not apply very large external force on the connector.
3. Keep the connector clean: The contact surface of the connector should be cleaned frequently to avoid poor electrical contact due to dirt or residue.
4. Pay attention to the use environment of the connector: Avoid using the connector in an environment that is too humid or high temperature, so as not to affect the quality of electrical contact.
5. Regularly check the electrical contact quality of the connector: The electrical contact quality of the connector should be checked regularly. If poor electrical contact is found, replace the connector in time.
The consequences of connector electrical contact failure may be as follows:
1. Electrical equipment failure: Due to poor electrical contact of the connector, the circuit of the electrical equipment is interrupted, causing the equipment to fail to work normally.
2. Electrical equipment accidents: Due to poor electrical contact of the connector, the circuit of the electrical equipment fails, and electrical equipment accidents, such as fires and explosions, may occur.
3. Affect the service life of electrical equipment: Poor electrical contact of the connector will cause frequent interruptions or unstable current supply to the circuit of electrical equipment, which will affect the service life of electrical equipment.
4. Increased maintenance costs: Equipment failures or accidents caused by connector electrical contact failures will increase maintenance costs.
5. Affect the working efficiency of electrical equipment: Equipment failure or accidents caused by electrical contact failure of connectors will affect the working efficiency of electrical equipment.
