Processing method of vehicle-mounted equipment wire harness

Abstract

The invention provides a processing method of a vehicle-mounted equipment wire harness. The processing method comprises the following steps that step 1, wire cutting is carried out, specifically, a required wire rod is selected, and the selected wire rod is cut into a required wire harness length section; step 2, cable marker sleeving is carried out, specifically, the cut wire harness is sleeved with a corresponding cable marker; step 3, peeling is carried out, specifically, the end part of the wire harness length section is peeled to expose a copper wire; step 4, wire connection is carried out, specifically, the copper wires of the two wire harness length sections are butted and crimped; step 5, fixing is carried out, specifically, in the step 4, before butt joint and crimping, the butt joint end of one wire harness length section is sleeved with a heat shrink tube, after butt joint and crimping, the heat shrink tube is moved to a crimping part, and the heat shrink tube is blown through a hot air blower until the heat shrink tube shrinks and fixes the crimping part; and step 6, wiring is carried out, specifically, the wire rod is arranged at a preset wiring position.

Description

technical field [0001] The invention relates to the field of cable related equipment, international classification number H01, and in particular relates to a processing method of a wire harness of vehicle-mounted equipment. Background technique [0002] With the rapid development of my country's economy and the continuous improvement of technological level, the proportion of vehicles in people's lives is getting higher and higher. The vehicle integrates a variety of electromechanical and hydraulic technologies, including fluid control, power transmission, exhaust gas treatment and other technologies; among them, the fluid control device controls the fluid system inside the vehicle, and the cable is a general term for optical cables, cables and other items. There are many uses of cables, mainly used for multiple functions such as control installation, connection equipment, and power transmission. The urea pump is an important part of the urea solution injection metering syste...

AI Technical Summary

Problems solved by technology

[0004] 1. In the vehicle-mounted system of the prior art, the urea pump system is included to process the exhaust gas, and the fluid output from the urea pump is controlled by a solenoid valve to open and close. At the same time, there are various sensors for sensing. At this time, there are many wiring harnesses correspondingly. Harnesses can easily become tangled if left unchecked

[0005] 2. The medium in the urea tank for vehicles in the prior art is prone to freezing in winter, resulting in failure to work normally in time. The solution includes heating and thawing

However, there are some working conditions, such as semi-fluid and semi-frozen conditions when partly frozen, and for example, the case where there is no time to thaw after heating. At this time, if the solenoid valve is opened and a small amount of fluid flows through, the small amount of fluid at this time cannot satisfy normal work. , the greater possibility is that a small amount of fluid is too rare or dispersed during the flow process, resulting in the formation of an ice film, so a certain amount of fluid needs to flow after converging in order to work normally

[0006] 3. The flow control mechanisms in the prior art are all active devices to control the flow, but lack of means of automatic control

[0007] 4. The temperature-sensitive materials in the prior art only have the basic function of expansion and contraction, but due to their material limitations, more complex functions cannot be realized

[0008] 5. In the existing technology, if there are too many designs in the valve body, it is often difficult to process due to internal processing.
