Abstract
The utility model relates to an automobile igniting system, and specifically relates to a high voltage damping cable comprising a connecting lead, two ends of the connecting lead are respectively connected with a spark plug joint and an igniting coil joint, the spark plug joint is sleeved outside with a spark plug sheath, the sheath comprises a sheath pipe and a sheath cap, and the sheath pipe and the sheath cap are in an one-body structure. The sheath sleeved outside the spark plug joint employs the one-body structure, gaps between joints are prevented, and a capability of screening electromagnetic interference by the high voltage damping cable is improved; and the spark plug sheath employs rubber material for preparation, not only full fitting between the sheath and the spark plug is realized, a requirement of plugging force is guaranteed, but also insulating property is improved. The high voltage damping cable realizes designs of shape and structure through dies, reduces production cost, installing procedure is simpler, and assembling work efficiency can be improved.
Description
Technical field
The utility model relates to the auto electronic product technical field, is specifically related to a kind of high voltage damper of automobile.
Background technology
The high voltage damper of automobile engine is for the vitals that connects spark plug and ignition coil, and it is sent to the high voltage electric energy of ignition coil on the spark plug discharges, thus the structure that realizes opening engine.
Existing high voltage damper comprises the connection wire, and the two ends of described connection wire are connected with respectively plug joint and ignition coil adapter, also is socketed with the spark plug sheath outside plug joint.Referring to Fig. 1, the existing spark plug sheath that is socketed on the plug joint comprises rubber sleeve 1, UP pipe 2 and the rubber cap 3 that is connected in turn.There is following defective in existing spark plug sheath: the heat resistance of (1) UP pipe 2 is poor, therefore must manage 2 front end at UP and connect one section rubber sleeve 1 and make UP pipe 2 away from spark plug; Therefore (2) because this spark plug sheath is split type, and the operation of its production and installation is many, not only production cost is high, and installation procedure increases, and operating efficiency is low; (3) being connected of its rubber sleeve 1 of split type spark plug sheath and UP pipe 2, UP pipe 2 with and the ease of connection of rubber cap 3 produce looseningly, produce electric leakage, its shield electromagnetic interference effect is also relatively poor simultaneously.
Summary of the invention
For the problems referred to above that prior art exists, the technical problems to be solved in the utility model is: how to improve the effect of sheath shield electromagnetic interference, reduce production costs.
Solve this technical problem, the utility model is achieved in that a kind of high voltage damper, comprise the connection wire, described connection wire two ends are connected with respectively plug joint and ignition coil adapter, described plug joint is arranged with the spark plug sheath outward, described spark plug sheath comprises protecting pipe and sleeve cap, and described protecting pipe and sleeve cap are structure as a whole.
Further, described spark plug sheath is made by elastomeric material.
With respect to prior art, the utlity model has following advantage:
1, since in the utility model high voltage damper the outer sheathed sheath of plug joint be the integral type structure, avoid occurring the slit between the joint, improved the ability of high voltage damper shield electromagnetic interference.
2, the ignition coil sheath adopts elastomeric material to make, and not only is conducive to the abundant applying of sheath and spark plug, has guaranteed the requirement of contact engaging and separating force, but also has increased insulating properties.
3, adopt elastomeric material to make the spark plug sheath, so that this spark plug sheath has resistance to elevated temperatures and resistance to low temperature, this spark plug sheath kept 48 hours under 200 ℃ or-40 ℃ of environment, without aging and crackle.
4, the utility model is realized the design of shape and structure by mould, has reduced production cost, and installation procedure is simpler, can improve the operating efficiency of assembling.
Description of drawings
The structural representation of spark plug sheath in Fig. 1-prior art.
The structural representation of spark plug sheath in Fig. 2-the utility model.
The structural representation of Fig. 3-the utility model high voltage damper.
Among the figure, 1-rubber sleeve, 2-UP pipe, 3-rubber cap, 4-spark plug sheath, 41-protecting pipe, 42-sleeve cap, 6-connect wire.
Embodiment
The below is to being described in further detail the utility model with accompanying drawing in conjunction with the embodiments.
Referring to Fig. 2 and Fig. 3, a kind of high voltage damper, comprise and connect wire 6, connect wire 6 two ends and be connected with respectively plug joint and ignition coil adapter, plug joint is arranged with spark plug sheath 4 outward, spark plug sheath 4 comprises protecting pipe 41 and sleeve cap 42, and protecting pipe 41 and sleeve cap 42 are structure as a whole.
Spark plug sheath 4 of the present utility model can adopt in the prior art arbitrarily insulation, resistant to elevated temperatures material to make, and the preferred rubber material is made.The spark plug sheath that elastomeric material is made can further it improve insulation effect and shield electromagnetic interference effect.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
