Application of heavy-duty connectors in construction machinery

ZJHK heavy-duty connector is made of high-strength alloy material or special engineering plastic, and after strict anti-corrosion and anti-rust treatment, it can resist corrosion, wear and impact in the working environment of engineering machinery. Its sealing structure design reaches the protection level of IP65 to IP68 , which can effectively prevent dust from entering and can work normally even in the case of short-term immersion in water. It is perfectly adapted to the harsh working environment of construction machinery and greatly reduces the connection failure caused by environmental factors.

In view of the strong vibration characteristics of construction machinery, ZJHK heavy-duty connectors have introduced crimping terminal type connectors to ensure that the plug and socket are tightly connected and not easy to loosen even under severe vibration . At the same time, the conductive parts inside are made of highly elastic materials to ensure good electrical contact during vibration, ensuring the continuity and stability of power and signal transmission, and providing reliable protection for the safe operation of construction machinery.

The motors, hydraulic pumps and other equipment in construction machinery have high power and high requirements for power transmission. The internal conductor of the ZJHK heavy-duty connector adopts a large-section, high-conductivity copper alloy , and through the optimized contact structure design, the contact resistance is reduced and the current carrying capacity is improved . Among them, the ZJHK HSB, HK,HM and HQ series inserts with features of compactness and  big rated current that are often used in remote controll can meet the power transmission needs of high-power equipment in construction machinery and ensure the stability of the power output of the equipment.

At the construction site of engineering machinery, the shorter the equipment maintenance time, the better. Therefore, in order to enable maintenance personnel to complete the removal and replacement of connectors in a short time without complicated tools and professional skills , ZJHK launched the quick lock heavy-duty connector, which greatly shortened the equipment downtime maintenance time and improved the attendance rate of construction machinery.

Excavators are one of the most common construction machinery in engineering construction. The motion control of their working devices (boom, dipper arm, bucket), engine operation monitoring, and the coordinated work of the hydraulic system all rely on stable electrical connections. Heavy-duty connectors are used to connect the lines between the excavator's cab control system and various actuators and sensors. For example, during the operation of the excavator's bucket, the sensor detects the position and force of the bucket in real time, and transmits the signal to the control system through the heavy-duty connector, which then issues instructions to control the hydraulic system. The anti-vibration performance of the heavy-duty connector ensures the stability of signal transmission when the excavator is working vigorously, and the high protection level prevents damage to the connection points by dirt, oil, etc., ensuring precise control of various actions of the excavator.

During the hoisting operation, the crane needs to realize complex actions such as boom extension, rotation, and lifting. The control of these actions depends on the stable transmission of power and signals. Heavy-duty connectors are widely used in the connection of crane boom control systems, winch motors, torque limiters and other components. In port crane operations, facing corrosive environments such as sea breeze and salt spray, the corrosion-resistant shell and high protection performance of the heavy-duty connector effectively protect the internal electrical components, ensure the continuous and stable transmission of power and signals, and ensure the safety and accuracy of crane hoisting operations. At the same time, its quick connection feature also facilitates the equipment assembly and maintenance of cranes in different operating scenarios.

The main function of a concrete pump truck is to transport concrete to a designated location through a pipeline. Its pumping system, boom motion control, and engine operating status monitoring all require reliable electrical connections. Heavy-duty connectors are used to connect the pump truck's control system with the pumping hydraulic system, boom sensor, and agitator motor. At the construction site, concrete pump trucks often come into contact with cement slurry and oil. The anti-oil and waterproof properties of heavy-duty connectors can effectively prevent these substances from corroding the connection points, ensuring that the pump truck can continuously and efficiently complete concrete delivery operations and reduce construction interruptions caused by connection failures.

During road construction, rollers are responsible for compacting materials such as soil, gravel, and asphalt. Strong vibrations are generated during operation. Heavy-duty connectors are used to connect components such as the roller's vibration control system, engine management system, and instrument panel. Their excellent anti-vibration performance ensures that electrical connections remain stable during high-intensity vibration operations of the roller, avoiding poor contact caused by vibrations and ensuring precise control of parameters such as the roller's vibration frequency and amplitude, thereby ensuring the quality of road compaction.
