Description

Technical Field

[0001] The utility model relates to the technical field of engines, in particular to an engine harness structure of a paving machine. Background Art

[0002] The engine harness of a paver refers to the wire harness that connects the various components of the engine (such as sensors, control modules, ignition systems, etc.). The engine harness plays a key role in the paver, transmitting power and signals to the various components of the engine to ensure the normal operation of the engine. The engine harness usually includes multiple insulated wires that are connected to the various components of the engine through connectors or plugs.

[0003] When the existing wiring harness is connected to the engine, part of the wiring harness is placed in the wiring box inside the body, but part of the wiring harness still needs to be exposed to the external working environment for wiring and conduction between devices, and thus this part of the wiring harness needs to be protected. Usually, a protective sleeve is installed outside the wiring harness for protection, but when the existing protective sleeve is installed on the wiring harness, the sleeve needs to be installed when the end of the wiring harness is not assembled. In the actual operation process, the long-term construction of the paver will cause the sleeve to be contaminated by engine oil, cement mortar, etc., and the protective sleeve is easily damaged if it is accidentally squeezed and hit during operation. At this time, if the sleeve is not replaced in time, it is easy to cause damage to the internal wiring harness. However, when the existing integrated sleeve is damaged in the later stage, it is not easy to replace, and it is even necessary to unplug the end of the wiring harness to disconnect the connection of the wiring harness body before the replacement operation can be carried out. The operation is inconvenient and affects the normal wiring operation of the wiring harness. Utility Model Content
