Abstract
The invention relates to a connection structure for a spring of an ignition coil and a spark plug. The connection structure comprises the ignition coil, the high-pressure spring and the spark plug, wherein one end of the high-pressure spring is connected with an output end of the ignition coil in a manner of interference fit, the other end of the high-pressure spring is connected with a conductive connection cap, and an end part of the high-pressure spring sleeves the conductive connection cap and is in close fit with the conductive connection cap,; and the conductive connection cap sleeves an end part of the spark plug, wherein a plurality of convex points are arranged on the inner wall of the conductive connection cap and in a manner of being corresponding to a clamping groove in the end part of the spark plug, and the conductive connection cap is connected with the spark plug through fit between the convex points and the clamping groove. The connection structure disclosed by the invention is capable of ensuring the connection stability of the spring of the ignition coil and the spark plug, thus normal working of an engine is ensured, and the service life of the ignition coil is prolonged.
Description
Technical field
The present invention relates to a kind of spark coil, be specifically related to the linkage structure of a kind of spark coil spring and spark plug.
Background technique
The spark coil of motor car engine and the connection reliability of spark plug very crucial, in existing technology, generally by spring, the spark energy of spark coil is guided on spark plug, and spring and spark plug Placement be withstand spark plug end face by spring or by spring housing in spark plug end, its contact substantially into a line or small size contact, when being subject to the affecting of ambient vibration, often there will be loosening, cause connection unreliable, thus cause energy transfer efficiency to reduce, affect the normal work of motor; Meanwhile, spark coil working life can also be shortened.
Summary of the invention
For prior art above shortcomings, the object of the invention is to how to solve spark coil spring and spark plug connective stability is poor, energy transfer efficiency is low, the problem in Influential cases fire coil working life, the linkage structure of a kind of spark coil spring and spark plug is provided, can the connective stability of guarantee point fire coil spring and spark plug, thus ensure the normal work of motor, and extend the working life of spark coil.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
The technical solution used in the present invention is such: the linkage structure of a kind of spark coil spring and spark plug, comprise spark coil, high pressure spring and spark plug, wherein, high pressure spring one end is connected with the output terminal interference fit of spark coil, and the end of described spark plug has draw-in groove; It is characterized in that: be connected with a conduction attachment cap at the other end of high pressure spring, the end sleeve of described high pressure spring to be located on conduction attachment cap and to tightly fit in together with conduction attachment cap; Described conduction attachment cap is set in the end of spark plug, and wherein, be provided with several salient point at the draw-in groove of the corresponding spark plug end of the inwall of conduction attachment cap, conduction attachment cap is connected with spark plug with the cooperation of draw-in groove by salient point.
As preferred technological scheme, conduction attachment cap is copper cap.
As preferred technological scheme, described salient point is 4, and within one week, is uniformly distributed around conduction attachment cap inwall.
Compared with prior art, tool of the present invention has the following advantages: structure is simple, easy to assembly, is connected by high pressure spring, effectively can ensures the connective stability of high pressure spring and spark plug by conduction attachment cap with spark plug; Further, between high pressure spring and conduction attachment cap, and conduction attachment cap contacts with forming surface equal between spark plug end, thus effectively improves energy transfer efficiency; And then ensure the normal work of motor, and extend the working life of spark coil.
In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the linkage structure schematic diagram of high pressure spring and conduction attachment cap.
In figure: 1-spark coil, 2-high pressure spring, 3-spark plug, 4-conducts electricity attachment cap, 5-salient point.
Below in conjunction with drawings and Examples, the invention will be further described.
The linkage structure of a kind of spark coil spring of embodiment and spark plug, comprises spark coil 1, high pressure spring 2 and spark plug 3.Wherein, high pressure spring 2 one end is connected by mechanical interference with the output terminal of spark coil 1, and the end of described spark plug 3 has draw-in groove.
Be connected with a conduction attachment cap 4 at the other end of high pressure spring 2, the end sleeve of described high pressure spring 2 to be located on conduction attachment cap 4 and to tightly fit in together with conduction attachment cap 4.During concrete enforcement, described conduction attachment cap 4 is copper cap, conducts electricity very well, and with low cost, long service life.Described conduction attachment cap 4 is set in the end of spark plug 3, and wherein, be provided with several salient point 5 at the draw-in groove of corresponding spark plug 3 end of the inwall of conduction attachment cap 4, conduction attachment cap 4 is connected with spark plug 3 with the cooperation of draw-in groove by salient point 5.Described conduction attachment cap 4 is for closing the open tubular structure in one end in one end, and when salient point 5 coordinates with draw-in groove, the conduction closed end of attachment cap 4 and the end face of spark plug 3 are close to.In course of working, described salient point 5 is 4, and within one week, is uniformly distributed around conduction attachment cap 4 inwall, thus makes the connective stability between conduction attachment cap 4 and spark plug 3 better.
Finally it should be noted that, above embodiment is only in order to illustrate technological scheme of the present invention but not restriction technologies scheme, those of ordinary skill in the art is to be understood that, those are modified to technological scheme of the present invention or equivalent replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of right of the present invention.
