According to the design of the valve chamber harness, the six connector terminals are integrated, the structure is simple, the number of needed valve chamber harnesses is reduced, the function of a single valve chamber harness is enriched, and the size of the valve chamber harness is smaller.
Description
Technical field
The present invention relates to a kind of cavaera wire harness, relate in particular to a kind of cavaera wire harness of six terminals.
Background technology
At present, in engine for safety and the consideration such as easy to use, sensor additional device can be set in engine, so just need many wiring interfaces, and on engine, also need to arrange the body of interface, 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, more cylinder interior lines body just need to be set on engine, very not attractive in appearance in profile like this, 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, provides a kind of cavaera wire harness of six terminals.
Object of the present invention is achieved through the following technical solutions: a kind of cavaera wire harness, comprises connecting portion and six Interface Terminals in the engine cylinder of interface position, upper end, middle fixed support, lower end; Interface position, upper end is hollow cylinder, outer upper end have for the helicla flute of matched interfaces clamping, and be provided with envelope pressure ring in interface position, upper end, envelope pressure ring upside is provided with tightening cover; Middle fixed support is flat trapezoid support, and has for fixing screw; In engine cylinder, connecting portion is cylinder, and six Interface Terminals pass the interior connecting portion of engine cylinder and equidistantly distribute along the circumferencial direction at interface position, upper end, and in engine cylinder, on connecting portion, cover has sealing ring.
Further improvement of the present invention is: on envelope pressure ring and tightening cover, have the location notch for location is installed, inner side, interface position, upper end is provided with the muscle shape projection of mating with location notch.
Further improvement of the present invention is: in engine cylinder, connecting portion arranged outside has oil seal ring.
Further improvement of the present invention is: connecting portion integral one-step molding in the engine cylinder of interface position, upper end, middle fixed support and lower end.
Further improvement of the present invention is: six Interface Terminals adopt resistant to elevated temperatures metal terminal and coordinate high temperature resistant wire coupling to use, and have reduced the diameter of Interface Terminal.
The present invention compared with prior art has the following advantages:
Cavaera wiring harness structure of the present invention is simple and by simple mechanism, six Interface Terminals are set together, realize the cavaera wire harness of six terminals, and through certain optimization process, by selecting high temperature resistant terminal and wire to coordinate, reduce terminal diameter size, thereby reduce the size of cavaera wire harness, reduced the impact of cavaera wire harness on engine.
brief description of the drawings:
Fig. 1 is the front view of cavaera wire harness of the present invention;
Fig. 2 is the vertical view of cavaera wire harness of the present invention;
Number in the figure: in the middle of interface position, 1-upper end, 2-, in the engine cylinder of fixed support, 3-lower end, connecting portion, 4-Interface Terminal, 5-seal pressure ring, 6-tightening cover, 7-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, connecting portion 3 and six Interface Terminals 4 in the engine cylinder that cavaera wire harness of the present invention comprises interface position, upper end 1, middle fixed support 2, lower end, and in the engine cylinder of interface position, upper end 1, middle fixed support 2 and lower end, connecting portion 3 is by grinding tool integral one-step molding, so both improved production efficiency, the process of the assembling of omitting, the intensity of the parts of one-shot forming is simultaneously larger, has ensured the fastness of cavaera wire harness.
Interface position, upper end 1 is hollow cylinder, outer upper end have for the helicla flute of matched interfaces clamping, and in interface position, upper end 1, be provided with envelope pressure ring 5, on envelope pressure ring 5, be provided with tightening cover 6.Ensure the sealing between connecting portion 3 in the interface position 1, upper end of whole cavaera wire harness and the engine cylinder of lower end by envelope pressure ring 5 like this, prevent that oil on engine is from upwards end interface position 1 seepage of connecting portion 3 in the engine cylinder of lower end, and be locked by tightening cover 6, so both fixed envelope pressure ring 5 and also six Interface Terminals have been formed and supported simultaneously.Seal on pressure ring 5 and tightening cover 6 simultaneously and have the location notch for location is installed, 1 inner side, interface position, upper end is provided with the muscle shape projection of mating with location notch.By such design, guarantee envelope pressure ring 5 and tightening cover 6 can be aimed at and put in place in installing, ensure that the perforate in envelope pressure ring 5 and tightening cover 6 can aim at completely with the position of six Interface Terminals 4, avoid producing displacement and make to seal pressure ring 5 deformation and cause sealing property to weaken.In engine cylinder, on connecting portion 3, cover has at least one sealing ring 7.
Middle fixed support 2 is flat trapezoid support, and has for fixing screw, by screw, whole cavaera wire harness is fixed on engine.In engine cylinder, connecting portion 3 is cylinder, and six Interface Terminals 4 pass the interior connecting portion 3 of engine cylinder and equidistantly distribute along the circumferencial direction at interface position, upper end 1.And six Interface Terminals 4 adopt resistant to elevated temperatures metal terminal and coordinate high temperature resistant wire coupling to use, reduce like this diameter of Interface Terminal 4, thereby can in less space, distribute, reduce the volume size of whole cavaera wire harness, saved cost and reduced the impact of cavaera wire harness on engine.In engine cylinder, connecting portion 3 arranged outside have oil seal ring simultaneously, can ensure that like this connecting portion 3 does not have oil seepage out with the link position of engine in engine cylinder.
Pass through technique scheme, cavaera wire harness of the present invention has been realized the cavaera wire harness of six Interface Terminals by simple structure, simple in structure like this, and by the design of six terminals, the quantity that has reduced the cavaera wire harness needing, has reduced the impact on starting, and body negligible amounts, also avoid affecting the attractive in appearance of engine, also avoided the triviality of operation.Adopt high temperature resistant terminal and wire to coordinate simultaneously, reduced terminal diameter size, thereby reduced the volume of whole cavaera wire harness, saved material cost, also reduced the impact of cavaera wire harness on engine simultaneously.
