Description
Technical field
The present invention relates to a kind of production technology of cavaera wire harness, particularly relate to a kind of production technology of cavaera wire harness of six terminals.
Background technology
At present, in order to safety and the consideration such as easy to use in engine, can sensor additional device be set in engine, so just need many wiring interfaces, and engine also needs the body that interface is set, traditional cylinder interior lines body is 4 terminal interface, along with the increase of function in engine, if continue to use such 4 terminal interface, just need to arrange more cylinder interior lines body on the engine, in such profile very unsightly, and it is more random and loaded down with trivial details to operate, and body can impact engine too much.
Summary of the invention
The object of the invention is, in order to overcome above deficiency, to provide a kind of production technology of cavaera wire harness of six terminals.
Object of the present invention is achieved through the following technical solutions: a kind of production technology of cavaera wire harness, comprises the following steps:
A, crimping: remove six conductors and six terminals, by one end all crimp type terminals of every root wire, the pulling-out force of terminal will reach 150N;
B, prepackage wire: by one end of non-for above-mentioned wire pressure side through sheath, and terminal is placed in sheath;
C, pre-install built-in sealing ring: after corresponding with sheath with the draw-in groove of swage, by sealing ring depress on earth;
D, pre-install built-in tightening cover: the boss of tightening cover is inwardly loaded sheath;
E, welding tightening cover: with swage and sheath planes align before welding, afterwards tightening cover is welded on sheath;
F, prepackage O type circle: by O type snare in the engine cylinder of sheath lower end on connecting portion;
G, twisted wire: six conductors is made in order, will be close to be clipped on stranding machine and carry out twisted wire by wire between two, the lay of twisted wire be 25-35mm;
H, will wire be worn the high temperature heat-resistant draw, blow heat-shrink tube, and by one end crimp type terminal of non-for wire pressure side;
I, to seal from terminal head portion 5mm place at heat-shrink tube;
J, by terminal bending 80 °.
Further improvement of the present invention is: six terminals adopt resistant to elevated temperatures metal terminal and coordinate high temperature resistant wire to mate and use, and reduce the diameter of Interface Terminal.
Further improvement of the present invention is: the welding air pressure in E step is 0.2MPa, and weld time is 0.6s, and firm time is 0.3s.
The present invention compared with prior art has the following advantages:
Present invention process step is simple, is set together by six terminals, coordinates by selecting high temperature resistant terminal and wire, reduce terminal diameter size, thus reduce the volume of whole cavaera wire harness, save material cost, also reduce the impact of cavaera wire harness on engine simultaneously.
accompanying drawing illustrates:
Fig. 1 is the structural representation of cavaera wire harness;
Number in the figure: 1-wire, 2-terminal, 3-sheath, 4-sealing ring.
embodiment:
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only for explaining the present invention, does not form limiting the scope of the present invention.
As shown in Figure 1, the production technology of cavaera wire harness of the present invention, comprises the following steps:
A, crimping: remove six conductors and six terminals, by one end all crimp type terminals of every root wire, the pulling-out force of terminal will reach 150N;
B, prepackage wire: by one end of non-for above-mentioned wire pressure side through sheath, and terminal is placed in sheath;
C, pre-install built-in sealing ring: after corresponding with sheath with the draw-in groove of swage, by sealing ring depress on earth;
D, pre-install built-in tightening cover: the boss of tightening cover is inwardly loaded sheath;
E, welding tightening cover: with swage and sheath planes align before welding, be welded on sheath by tightening cover afterwards, air pressure is 0.2MPa, and weld time is 0.6s, and firm time is 0.3s;
F, prepackage O type circle: by O type snare in the engine cylinder of sheath lower end on connecting portion;
G, twisted wire: six conductors is made in order, will be close to be clipped on stranding machine and carry out twisted wire by wire between two, the lay of twisted wire be 25-35mm;
H, will wire be worn the high temperature heat-resistant draw, blow heat-shrink tube, and by one end crimp type terminal of non-for wire pressure side;
I, to seal from terminal head portion 5mm place at heat-shrink tube;
J, by terminal bending 80 °.
Also to detect after cavaera wire harness completes: carry out wire electrical testing, air tightness test; Visual inspection: whether ultrasonic bonding puts in place, namely after welding, whether swage flushes with sheath edge; Whether the lay of twisted wire reaches requirement, and namely whether the focal length of twisted wire is 25-35mm; Whether O type circle installs to position; Whether use correct heat-shrink tube, whether heat-sealing puts in place, and the surface uniform after heat-sealing puts in place is attractive in appearance; Whether the bending angle of terminal is 80 °; Wire harness surface can not have adhesive tape to stick stain and spot.
The present invention ensure that the sealing in the sheath of the production technology of whole cavaera wire harness and engine cylinder between connecting portion by sealing ring, prevent the oil on engine from connecting portion in the engine cylinder of lower end to jacket leak, and be locked by tightening cover, so both secure sealing ring and also support is formed to six terminals simultaneously.Sealing ring and tightening cover have the location notch for installing location simultaneously, the muscle shape projection of mating with location notch is provided with inside sheath, by such design, ensure that sealing ring and tightening cover can be aimed at when installation to put in place, ensure that the perforate in sealing ring and tightening cover can be aimed at completely with the position of six terminals, avoid producing displacement and making sealing ring deformation and cause sealing property to weaken.On sheath, cover has at least one O type circle, can ensure so not have oil seepage out at the link position of sheath and engine.Six terminals adopt resistant to elevated temperatures metal terminal and coordinate high temperature resistant wire to mate and use, which reduce the diameter of terminal, thus can distribute in less space, reduce the volume size of the production technology of whole cavaera wire harness, saved cost and reduced the impact of production technology on engine of cavaera wire harness.
Present invention process step is simple, is set together by six terminals, coordinates by selecting high temperature resistant terminal and wire, reduce terminal diameter size, thus reduce the volume of whole cavaera wire harness, save material cost, also reduce the impact of cavaera wire harness on engine simultaneously.
