XCMG XE2000 Excavator Connector Assembly (318307819): The Efficient Connection Hub of the Circuit System

In the complex circuit network of the XE2000 large mining excavator, the connector assembly is the core hub for achieving precise communication and power transmission between various electrical modules. Its performance directly affects the overall machine’s control response speed and operational safety. XCMG’s original connector assembly (part number: 318307819) is specially customized for the heavy-duty working conditions of this model. With its micro-precision contact technology, military-grade protection capabilities, and deep original factory compatibility, it becomes a reliable guarantee for the stable operation of the circuit system under high-intensity mining operations.

Micro-precision contact cluster design, zero signal transmission loss

The intelligent control system of the XE2000 excavator relies on real-time data interaction between multiple sensors and control units, placing stringent requirements on the accuracy and stability of signal transmission. This connector assembly features a multi-contact cluster layout design. The pins are made of high-purity beryllium copper alloy, with a surface roughness ≤0.02μm after nano-gold plating. The single-contact resistance is stably controlled within 1.5mΩ, achieving ultra-low loss synchronous transmission of multi-channel electrical signals. The elastic contact structure has been optimized through 30,000 mating fatigue tests, and with a tolerance of 0.02mm, it maintains stable contact at all contacts even under high-frequency vibration conditions, effectively preventing signal interruption and data delay. Whether it’s hydraulic system pressure feedback, engine condition monitoring, or operation command execution, it achieves millisecond-level response, ensuring an overall machine control precision improvement of over 20%.

Comprehensive sealing protection system ensures worry-free operation in extreme environments

Dust intrusion, oil immersion, and alternating high and low temperatures in mining operations are major causes of failure in electrical connection components. The 318307819 connector assembly features an integrated metal insert reinforcement structure. The housing is made of impact-resistant modified PBT engineering plastic with an impact resistance of 28kJ/m², and is UL94 V0 flame-retardant certified. The interface innovatively employs a quadruple sealing design, including a built-in fluororubber main sealing ring, a silicone rubber dust plug, a metal locking ring, and a waterproof gasket, achieving an IP6K9K protection rating. This completely withstands high-pressure water jets, prolonged oil immersion, and high-concentration dust intrusion. Extreme environment testing has verified stable performance within an ultra-wide temperature range of -55℃ to 140℃. A 650-hour salt spray test showed no rust. In humid and dusty mining environments, its service life is extended by 85% compared to ordinary connectors, significantly reducing the risk of unplanned downtime.

Fully compatible with original factory parameters, seamless system integration

As a core electrical connection component of the XE2000 excavator, the electrical parameters and mechanical dimensions of this connector assembly have undergone full factory calibration. Designed for the 12V/24V hybrid circuit architecture of the entire machine, its single-channel rated current reaches 35A, and the overall insulation withstand voltage is ≥2000V, perfectly matching the power supply and signal transmission requirements of key equipment such as the main controller, sensor clusters, and hydraulic actuators. The connector pin definitions strictly adhere to the SAE J1939 industrial bus standard, with a mating error between the mounting positioning hole and the equipment interface ≤0.015mm, enabling quick and precise assembly without any modifications. Compatibility testing with the entire machine’s circuit system has been verified, completely avoiding signal interference and component burnout caused by parameter mismatches, ensuring efficient and coordinated operation of the circuit system.

Modular integrated design for convenient and efficient installation and maintenance

Considering the ease of maintenance requirements for mining equipment, this connector assembly adopts a modular integrated design, consolidating multiple independent connection functions into one, reducing pipeline connection points by more than 30%. The assembly is equipped with a quick-locking snap-fit ​​structure, along with visual alignment markers, allowing installers to confirm proper connection through audible feedback. A single person can complete the assembly operation, improving installation efficiency by 40%. Built-in anti-misconnection mechanical coding structure and differentiated interface designs for different functional modules physically eliminate the risk of incorrect connection. The component housing has a reserved detection window, allowing for rapid testing of internal contact status using specialized instruments. Fault diagnosis can be completed without disassembly, significantly reducing maintenance time.

Full Lifecycle Quality Control, Multiple Redundancy for Safety Performance

XCMG implements stringent full lifecycle quality control for the 318307819 connector assembly. From raw material selection to finished product delivery, it undergoes 28 professional tests. Each batch of products passes vibration testing (10-4000Hz), shock testing (2500G acceleration), and damp heat cycling testing (-40℃ to 85℃, 95% humidity) to ensure structural stability and electrical performance under extreme conditions. The product complies with IEC 60529 protection standards and ISO 13407 mining safety specifications, and features built-in overcurrent protection, short-circuit protection, and surge suppression functions, effectively preventing equipment damage caused by circuit abnormalities and providing multiple redundancy guarantees for operator and equipment safety.

XCMG XE2000 excavator connector assembly (part number 318307819) – Utilizing micro-precision manufacturing processes to ensure smooth signal transmission, employing military-grade protection to withstand environmental challenges, and featuring original equipment manufacturer (OEM) fitment to guarantee system compatibility, this is an indispensable and highly efficient connection hub for the electrical systems of large mining excavators.
