Abstract
The invention provides a glue immersion technological method for breaking capillarity of an engine wiring harness, aiming at solving the problem that the oil is seeped in an ECU due to the capillarityof the diesel engine wiring harness. The technical proposal is as follows: the harness lead connected with an injector wiring in an automobile engine wiring harness is broken; subsequently the lead c opper cores at the broken position are staggered sequentially and welded together by an ultrasonic wire welder; an anaerobic adhesive is dipped at the welding position; the anaerobic adhesive is sucked inside the lead copper cores by the capillarity generated by the apertures in the lead copper cores; subsequently the welding position is sheathed by an oil-resistance composite dual-layer thermal contracting pipe to carry out sealing insulation; the anaerobic adhesive sucked in the lead wire cores is solidified under a condition of meeting metal ions and having no oxygen; and the solidified anaerobic adhesive fills in and blocks the clearances in the lead copper cores.
Description
Technical field
The present invention relates to the automobile engine wire harness, especially block the gum dipping process method of engine wiring harness capillarity.
Background technology
Existing electric spraying diesel automobile engine wire harness, connecing the fuel injector wiring partly is installed in the rocker arm chamber, because copper core part that electric wire inside is made up of many thin copper wires, there is the slit between copper wire and the copper wire, the indoor lubricating oil of engine rocker is penetrated among the engine electric-controlled ECU with capillarity by this slit, thereby pollute the ECU electric interfaces, cause ECU electric interfaces electrical property to descend, influence the engine operate as normal.
Summary of the invention
For the capillarity of eliminating the Diesel engine wire harness causes the problem of oil impregnate to ECU, the present invention proposes a kind of gum dipping process method of blocking engine wiring harness capillarity.
For this reason, technical scheme of the present invention is as follows: the harness portion lead that connects the fuel injector wiring in the automobile engine wire harness is interrupted, then the lead copper core that interrupts the position is staggered successively, adopt ultrasonic wave electric wire bonding machine that lead copper core is welded together; Soak anaerobic adhesive in the welding position, the capillarity that the slit that utilizes lead copper in-core portion to exist produces sucks lead copper in-core portion with anaerobic adhesive, carry out sealed insulation at welding position overcoat oil resistant composite double layer heat-shrink tube then, the anaerobic adhesive that sucks lead inside run into metal ion again under the condition of no oxygen anaerobic adhesive solidify, the anaerobic adhesive after solidifying fills up obstruction with lead copper in-core slit.
To further describing of technique scheme, be lead to be interrupted soak anaerobic adhesive, at overcoat oil resistant composite double layer heat-shrink tube with air-heater 145 ℃ of down heating, thereby make in the composite double layer heat-shrink tube contained PUR separate out back cooled and solidified sealed insulation.
Described Diesel engine wire harness connects that the fuel injector lead is higher because of working temperature, environment is more abominable, for guaranteeing the useful life of wire harness functional reliability and 10 years, adopted the import T6 lead of 200 ℃ of heatproofs and oil resistant, employing interrupts behind the gum dipping process from interrupting one section T3 lead that adopts 125 ℃ of heatproofs of ECU, and the use amount of T6 lead reduces production costs in the wire harness thereby reduced.
Beneficial effect: because the anaerobic adhesive after solidifying fills up obstruction with lead copper in-core slit, blocked the capillarity of wire harness, avoided oil impregnate to ECU.This method has characteristics such as production technology is simple, effect is obvious, can be applicable in the various automobile engine wire harness productions.
Description of drawings
Fig. 1 is an enforcement schematic diagram of the present invention.
Fig. 2 is the assembling schematic diagram of engine wiring harness.
Shown in the figure: the 1st, T6 lead, the 2nd, oil resistant composite double layer heat-shrink tube, the 3rd, electric wire copper core, the 4th, electric wire copper core, the 5th, T3 lead, the 6th, engine wiring harness, the 7th, rocker arm chamber, the 8th, ECU.
Embodiment
As shown in Figure 2, engine wiring harness 6 one ends are connected with ECU8, and an end is connected in the rocker arm chamber 7.
Engine wiring harness 6 as shown in Figure 1, 2 interrupts lead at the A place and to overlap oil resistant then with copper cash ultrasonic welding machine welding back impregnation and contain the glue heat-shrink tube and do the insulation encapsulation process.Be specially: the harness portion lead that connects the fuel injector wiring in the automobile engine wire harness is interrupted, one section that is connected with ECU is adopted T3 lead 5, other one section is T6 lead 1, then the lead copper core 3,4 that interrupts the position is staggered successively, adopt ultrasonic wave electric wire bonding machine that lead copper core 3,4 is welded together; Soak anaerobic adhesive in the welding position, the capillarity that the slit that utilizes lead copper in-core portion to exist produces sucks lead copper in-core portion with anaerobic adhesive, carry out sealed insulation at welding position overcoat oil resistant composite double layer heat-shrink tube 2 then, the anaerobic adhesive that sucks lead inside run into metal ion again under the condition of no oxygen anaerobic adhesive solidify, the anaerobic adhesive after solidifying fills up obstruction with lead copper in-core slit.
Machining process is: electric wire blanking → lead two ends stripping insulated hull, crimp type terminal → cover contain glue heat-shrink tube, ultrasonic bonding, soak anaerobic adhesive, the composite double layer heat-shrink tube heats → start packing → assembling → and the cover bellows, adorn annex → energising detection → check, pack.The detailed process of wherein soaking anaerobic adhesive is: electric wire interrupts blanking → lead two ends stripping insulated hull → cover and contains glue heat-shrink tube, ultrasonic bonding → soak anaerobic adhesive → the contain heating of glue heat-shrink tube, insulated enclosure processing.Adopt low viscosity anaerobic adhesive, working temperature moderate.
As shown in fig. 1, be described to the one section employing T3 lead 5 that is connected with ECU, other one section is T6 lead 1.Adopting dissimilar leads is in order to reduce cost, also can to adopt lead of the same type.Lead used among the present invention also can be the lead of other type, as long as it is just passable to be used for engine wiring harness.
Claims (2)
1. gum dipping process method of blocking engine wiring harness capillarity, step is: the harness portion lead that connects the fuel injector wiring in the automobile engine wire harness is interrupted, then the lead copper core that interrupts the position is staggered successively, adopt ultrasonic wave electric wire bonding machine that lead copper core is welded together; Soak anaerobic adhesive in the welding position, the capillarity that the slit that utilizes lead copper in-core portion to exist produces sucks lead copper in-core portion with anaerobic adhesive, carry out sealed insulation at welding position overcoat oil resistant composite double layer heat-shrink tube then, the anaerobic adhesive that sucks lead inside run into metal ion again under the condition of no oxygen anaerobic adhesive solidify, the anaerobic adhesive after solidifying fills up obstruction with lead copper in-core slit.
