Fixing structure of engine cylinder internal wire harness assembly and method for fixing wire harness assembly

Abstract

The invention provides a fixing structure of an engine cylinder internal wire harness assembly and a method for fixing the wire harness assembly. The fixing structure of the engine cylinder internal wire harness assembly comprises the wire harness assembly, a wire harness sheath matched with the wire harness assembly wraps the wire harness assembly, and at least one fixing part is arranged on the wire harness sheath. The wire harness assembly is fixed through the following steps that one end of the wire harness assembly is connected with a binding post of an engine cylinder internal oil atomizer through a wire harness terminal, the other end of the wire harness assembly is fixed in a mounting hole in the front end of an engine cylinder cover through an inserting connector, and the fixing parts of the wire harness sheath are fixed to the cylinder cover in sequence in a matching mode. According to the scheme, the assembling and fixing positions of wire harnesses are made to be clear through a reasonable wire harness distribution mode, and the design space is utilized effectively; meanwhile, the wire harness sheath performs protecting and guide fixing functions on the wire harnesses, and the performance of resistant to high temperature, resistant to corrosion, resistant to vibration and resistant to abrasion is achieved.

Description

technical field [0001] The invention relates to the technical field of auto parts installation, in particular to a fixing structure of a wire harness assembly in an engine cylinder and a method for fixing the wire harness assembly. Background technique [0002] With the continuous development of electronically controlled diesel engines, the requirements for the power, economy, and emission performance of diesel engines are getting higher and higher; therefore, improving the performance of electronically controlled engine in-cylinder wiring harnesses has become the focus of attention. This requires that the wiring harness in the cylinder of the diesel engine can not be loosened or damaged during high-speed operation, so as to ensure the transmission of signals and avoid adverse effects. [0003] The layout of the overhead camshaft engine makes the space of the cylinder head concentrated, more parts need to be arranged in the limited space, and the space left for the wiring ha...

Problems solved by technology

[0004] The traditional engine wiring harness is protected by bellows and fixed inside the engine with cable ties and harness brackets. When the vibration of the engine continues to increase, the fixing of the cable ties is likely to cause loosening and external damage to the wiring harness, and the resistance of the wiring harness of this design Corrosion and anti-pollution ability is poor, oil stains easily penetrate into the wiring harness, affecting the reliability of the wiring harness
