Put an end to the problem caused by the temperature rise of inferior connector, and share the experience of old battery connector manufacturers:Lithium batteries can be seen everywhere in life, large and small electronic devices have its existence, and connector is an indispensable component between battery packs, its quality has a great impact on the life of lithium batteries.I still remember that some battery connector manufacturers did not pay attention to quality in order to save costs, which finally led to the whole machine explosion.This shows how important a good quality connector is for lithium batteries.
Battery explosion beside items, there is a reason is a high temperature when the battery to charge and discharge, large current through the connector causes of thermal effect, when the temperature rise of connectors, more than the temperature of the battery pack, the temperature will be passed inside the battery, which affect the stability of the battery, battery for a long time at high temperature near the connector, it could explode.Therefore, battery connector manufacturers need to make the connector achieve low temperature rise characteristics.
So how do battery connector manufacturers do it?Small series through the exchange with a connector manufacturer for more than 10 years to come to the following points for your reference:
- Maintain the optimal contact area between the terminal and the pin to effectively reduce the contact resistance, the over-current density and the current temperature rise
- In order to improve the heat dissipation function, the surface is designed as a corrugated arc
3.USES the import high quality copper metal materials, high conductivity, the temperature rise of the over current stability, plastic material USES excellent heat-resistant properties of LCP (not absolute, by using the environment, performance to choose plastic material such as: PA66, PEKK, etc.), low heat resistance of < 177 degrees c in the heat of 177 ~ 243 degrees Celsius high heat-resistant > 243 degrees Celsius, with characteristics of high strength and high toughness, satisfies the requirement of fire at the same time, a higher coefficient of thermal conductivity, speed up the heat
- Select plating suppliers strictly to ensure uniform coating thickness and select excellent metal materials to effectively reduce the temperature rise through current
- The stable and firm multi-point pressing technology can effectively reduce the temperature rise of the connection between the wire nose and the wire, and ensure the consistency of the temperature rise
Low temperature and high quality connector has become the trend of battery connector development, battery connector manufacturers to make safe and reliable products is the fundamental, pay attention to quality and safety is a production enterprise's most basic requirements, only good quality to win the trust of customers, can bring good reputation, finally achieve a win-win situation.
