EW-LP Series Device Connectors

The EW-LP20 series connectors are designed for high-precision, high-quality automatic insertion. With features such as self-locking device and waterproof and dustproof, it is widely used in various challenging environments.

I believe we all know a common sense, the conductors in the circuit will generate heat when energized, the electrical connector is the same, our electrical connector is connected to a component in the circuit, when the current through the circuit, there will be resistance to the part of the heat and temperature rise, for the electrical connector, its resistance is mainly contact resistance, crimping or welding resistance and the resistance of the conductor itself, so the electrical connector In the use of the process will undoubtedly heat up.

It is normal for electrical connectors to generate heat during use

Electrical connector heating will not affect the service life is determined by the temperature rise performance of the electrical connector, the electrical connector insulator and accessories are mainly composed of plastic and silicone rubber, etc., the main body of certain electrical connectors or plastic, they are subject to the limit of temperature, if the electrical connector in the process of working heat temperature exceeds the limit of the material can withstand the temperature will lead to accelerated aging of the material and affect the electrical connector To reflect how high a electrical connector can withstand the heat is the temperature rise performance of the electrical connector, and the temperature rise value is a direct reflection of the most important parameters of temperature performance, and thus to see whether a electrical connector can work under the rated current to withstand the heat generated by the key is whether the temperature rise value to meet the corresponding national standard requirements.

Our electrical connectors are made of high-strength PA66 material, with good wear resistance and pressure resistance, and in the case of not exceeding the rated current, can be used in cold and high temperature conditions, the temperature rise value of -40℃-+105℃, so the normal work of using our waterproof electrical connectors heat and will not affect its life.
