You can imagine with me: the temperature of outdoor energy storage cabinets can soar to 70℃ under the sun, and the internal battery connectors can expand due to high temperature, resulting in a surge in impedance; the humidity sensor in the cold chain warehouse may fail or even be scrapped due to moisture or corrosion intrusion caused by the freezing and cracking of the connector seal ring. In fact, this is not just a fantasy, but a microcosm of many industrial accidents.
When a connector is in an extreme environment for a long time, it will be very fragile if it does not have sufficient high and low temperature resistance. Therefore, when used in harsh high or low temperature environments, it is necessary to consider the temperature tolerance of the connector and choose an industrial-grade connector with better material and design and wide temperature tolerance to provide power, signal or data transmission.
What challenges does high and low temperature application environment pose to connectors?
Industrial-grade connectors are usually required to have strong enough resistance to high and low temperatures. So what are the main aspects of achieving this demand?
1. Temperature affects material properties
In harsh high temperature environments, connector materials may soften, deform, or have reduced insulation performance; low temperatures may cause the material to become brittle, shrink, or have poor contact, which not only affects electrical transmission performance, but also reduces mechanical strength.
2. It is easy to cause the contact performance of the contact parts to deteriorate
When the temperature in the application environment fluctuates drastically, the metal material of the connector contact (such as copper alloy) may cause micro-wear due to differences in expansion coefficients. After accumulation during long-term use, it can easily lead to signal distortion or power outages.
3. Sealing and protection failure
When used in harsh and extreme temperature environments for a long time, the sealing materials (such as silicone) of the connector may age and loosen, causing foreign matter such as water vapor and dust to enter, causing short circuits or corrosion in the internal transmission path and other faults.
YM series' excellent high and low temperature resistance performance comes from ingenuity and design
1 -25℃~+85℃ wide temperature performance
The YM series industrial waterproof connector is a high-performance waterproof connector with a full plastic shell made of SABIC high-quality outdoor engineering plastics. It uses a very dense and reliable spiral bayonet connection method, which is stable. The full plastic shell makes it have better corrosion resistance. Of course, its high and low temperature resistance is also good, and it can adapt to a wide temperature environment of -25℃~+85℃.
2 How does the YM series connector ensure high and low temperature resistance?
01 Preferred materials:
① The shell and insulator are made of SABIC materials, which are more resistant to high and low temperatures than ordinary plastics
② The contact parts are made of high-quality copper alloy, which has high temperature stability
③ The sealing ring is high-quality and highly elastic silicone, which can still maintain high elasticity under extremely high or low temperatures
02 Structural design optimization:
① The internal multi-layer sealing structure can improve air tightness and prevent condensation problems caused by extreme temperature differences
② Optimize the terminal structure to reduce the risk of contact failure caused by temperature changes
03 Pass high and low temperature professional tests:
Passed professional tests by UL/TUV authorized laboratories, with a high and low temperature resistance range of -25℃~+85℃, meeting technical standard requirements
Case sharing: Energy storage equipment
Energy storage equipment is a system that stores energy and releases it when needed. It is used to balance energy supply and demand, improve grid stability, integrate renewable energy, and provide emergency power. Usually, when selecting connectors for energy storage equipment and supporting equipment in outdoor scenes, factors such as current carrying capacity, protection level, plug-in life, and high and low temperature resistance should be considered. Therefore, energy storage equipment mostly uses industrial-grade connectors.
The high and low temperature resistance of the connector is very important for energy storage equipment. For example, the commonly used photovoltaic energy storage equipment is exposed to extreme outdoor temperature environments for a long time (affected by regional temperature differences and seasonal temperature differences), and the connector needs to be used in a wide range of temperature environments.
The 12-core signal connector of the YM series of CNLINKO is widely used in energy storage equipment such as photovoltaic energy storage. It mainly realizes data interaction with the system and the power grid dispatching center; transmits the voltage/frequency phase signal of the power grid, ensures that the inverter output is strictly synchronized with the power grid, and other functions. Because this connector is designed based on industrial standards and uses high-quality materials such as SABIC, it guarantees that it has stronger high and low temperature resistance and can operate stably in a harsh temperature environment of -25℃~+85℃.
In addition, this series of products also has IP68/IPX9K protection level, all-plastic high corrosion resistance, UL-94 V0 flame retardant, UV resistance and other characteristics, which is also the reason why the YM series industrial-grade connector is highly matched with energy storage equipment products.
At present, this product is also widely used in many fields such as automation equipment, electronic equipment, new energy, electromechanical equipment, mechanical equipment, instrumentation, ships, vehicle-mounted equipment, medical equipment, security, LED display, etc.
