How to Select Energy Storage Connector

With the increasing market demand for connectors, a wide variety of connectors have emerged, and the most common connectors such as high current connector, storage device connector or storage battery connector. In general, the basic performance of connectors can be divided into three categories: mechanical performance, electrical performance and environmental performance.

1.Mechanical property the pull-out force is an important mechanical property in terms of connection function

Pull-in force is divided into pull-out force and pull-in force, the two requirements are different. There are provisions for maximum insertion force and minimum separation force in the relevant standards, which indicates that the insertion force should be small and that too small a separation force will affect the reliability of the contact.

The plug force and mechanical life of the connector are related to the quality of the plating layer on the contact part of the contact part structure and the precision of the contact part arrangement dimension.

 

2.Electrical properties the main electrical properties of a connector include contact resistance, insulation resistance, and resistance strength

1 Contact resistance. High quality electrical connectors should have low and stable contact resistance. The contact resistance of connectors varies from a few milliohms to tens of milliohms.

2 insulation resistance, a measure of the insulation performance of electrical connectors between the contacts and between the contacts and the housing, with orders of magnitude ranging from hundreds to thousands of Megohm.

3 electric resistance strength, or voltage, medium voltage, is a characterization of the connector between the contact parts or between the contact parts and the shell withstand the rated test voltage capacity

3.Environmental performance common environmental performance including temperature resistance, moisture resistance, vibration and impact, etc.

1 the maximum working temperature of the current connector is 200 °C, and the minimum temperature IS-20 °C. It is generally considered that the working temperature should be equal to the sum of the ambient temperature and the contact temperature. In some specifications, the maximum allowable temperature rise of connectors at rated operating current is specified.

2 resistance to moisture invasion will affect the insulation performance of the connection, and rust metal parts.
3 resistance to salt fog, when the connector works in the environment containing moisture and salt, the surface treatment layer of the metal structure parts and contact parts may produce electrochemical corrosion, which affects the physical and electrical properties of the connector.

4 vibration and shock, anti-vibration and shock are important performance of electrical connector, it is an important index to test the sturdiness of mechanical structure and electrical contact reliability of electrical connector. In the relevant test methods are clearly specified. Peak acceleration and the time of electrical continuity interruption shall be specified in the impact test.

5 Other environmental performance according to the use of requirements, electrical connector other environmental performance and sealing, low air pressure, etc. .
