The ETC charging system is an intelligent transportation system that uses wireless communication technology to automatically complete toll collection without stopping. It greatly improves traffic efficiency and significantly reduces operating costs through contactless payment, and is one of the key facilities in the development of intelligent transportation and vehicle networking.
In the roadside unit of the ETC system, continuous power input is required to ensure the normal operation of the roadside unit. Currently, the industry mostly uses industrial-grade connectors to ensure uninterrupted and stable power transmission in outdoor and road environments. The new DH16 series connectors of CNLINKO released at the end of last year have been widely used in the ETC system due to their powerful product performance and matching degree.
DH16 series connectors: Multiple technologies protect the ETC system and make it run as steadily as a rock
The roadside unit of the ETC toll collection system will be affected by multiple complex factors during use, such as extreme high temperature and severe cold, rain and humidity, dust and particles, ultraviolet rays, vibration caused by vehicle traffic or strong wind, etc. This is also an important factor in testing whether the connector can provide continuous, stable and uninterrupted electrical transmission. The DH16 series industrial-grade connector of CNLINKO has strong performance and high environmental tolerance, and is a very suitable connection solution for the ETC toll collection system.
01. IP68/IPX9K, no fear of rain and humidity on the road
CNLINKO DH16 industrial-grade connector has passed IP68/IP69K certification standard testing and can ensure the sealing of internal components in heavy rain, impact water flow or dusty environments; the multiple composite sealing design (internal multiple silicone rings and structural coupling) prevents the intrusion of water vapor and particles.
02. Highly matches the connector requirements of harsh temperature and corrosion factors
In road scenes, there are acid rain, sulfur/nitrogen compounds in automobile exhaust, environmental pollutants and other corrosive factors that corrode the connectors used in the ETC toll collection system. The above-mentioned DH16 series industrial-grade connectors of CNLINKO have strong anti-corrosion performance, and the salt spray test time is ≥72 hours, which can resist the influence of corrosive factors in the above environment; its operating temperature range covers -40℃ to +85℃, which can be applied to the ambient temperature of high-cold and high-heat areas, and the thermal expansion coefficient of the materials is matched to prevent the sealing failure caused by temperature cycle.
03. Highly reliable connection locking design, loose connection is no longer a pain point
Continuous vibration caused by vehicle traffic or strong winds can cause the connection of the locking structure to loosen or fail, which in turn increases the wear of the pins. The DH16 series industrial connector from CNLINKO uses a spiral bayonet connection and three-point locking method, with a separation force of ≥500N. The connection and coupling are tighter and firmer, which can avoid looseness and poor connection contact. In addition, the flexible cable clamping structure at the tail can prevent the firmness of the internal wiring points from being damaged by external forces such as wind.
Summary: After on-site deployment, the stability of ETC has been improved and system maintenance has been significantly reduced.
At present, this DH16 series connector has been widely used in the ETC system. Practice has proved that its high protection level (IP68/IPX9K), corrosion resistance and vibration resistance design have significantly improved the stability of the equipment in extreme outdoor environments. Users have reported that this connector effectively solves problems such as salt spray erosion, temperature difference deformation and mechanical looseness, ensuring the continuous operation and low failure rate of the ETC system, and extending the system maintenance cycle. Overall evaluation: This new industrial-grade connector has excellent performance and is an indispensable core component of the intelligent transportation system.
