Abstract
An ignition coil capable of effectively avoiding electromagnetic interference risks relates to an automobile engine accessory. The one end of high-pressure sheath and the one end of coil housing can be dismantled fixed link, and the inside of high-pressure sheath is equipped with the spring along its length direction, the spring closes on the one end of coil housing and cup joints fixedly with the one end of falling the resistance of making an uproar, fall the one end contact cooperation of the other end of the resistance of making an uproar and high-pressure output piece, the other end of high-pressure output piece and secondary high-pressure coil's one end fixed connection, secondary high-pressure coil and high-pressure output piece all set up the inside at the coil housing, just the casing closely the suit is in the outside of falling. The utility model discloses a parasitic current is after the resistance consumption of making an uproar falls, but the parasitic current of effective consumption reduces in a large number to producing electromagnetic wave radiation outward to effectively reduce electromagnetic wave energy radiation, avoid the outer condition that the emission radiation probably exists and exceeds standard, and then accord with the requirement of national standard electromagnetic compatibility.
Description
Technical Field
The utility model relates to an automobile engine accessory, especially an effectively avoid ignition coil of electromagnetic interference risk.
Background
With the implementation of relevant policies, the electromagnetic compatibility requirements for ignition coils are further tightened. The common ignition coil for the vehicle in the prior art does not have an electromagnetic suppression structure, so that the condition that the emitted radiation exceeds the standard possibly exists, and the requirement of national standard electromagnetic compatibility is further violated.
Disclosure of Invention
For solving the problem that exists among the background art, the utility model provides an effectively avoid ignition coil of electromagnetic interference risk.
The purpose is achieved, the utility model adopts the following technical proposal: the utility model provides an effectively avoid ignition coil of electromagnetic interference risk, includes secondary high-voltage coil, high-voltage output piece, coil casing, falls the resistance of making an uproar, high-voltage sheath and spring, fixed link can be dismantled with coil casing's one end to high-voltage sheath's one end, and high-voltage sheath's inside is equipped with the spring along its length direction, the spring closes on coil casing's one end and the one end of falling the resistance of making an uproar cup joints fixedly, fall the other end of the resistance of making an uproar and the one end contact cooperation of high-voltage output piece, the other end of high-voltage output piece and secondary high-voltage coil's one end fixed connection, secondary high-voltage coil and high-voltage output piece all set up the inside at.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses a parasitic current is after the resistance consumption of making an uproar falls, but the parasitic current of effective consumption reduces in a large number to producing electromagnetic wave radiation outward to effectively reduce electromagnetic wave energy radiation, avoid the outer condition that the emission radiation probably exists and exceeds standard, and then accord with the requirement of national standard electromagnetic compatibility.

Fig. 1 is a schematic view of the overall structure of the present invention.
Detailed Description
The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.
The first embodiment is as follows: as shown in figure 1, the utility model discloses an ignition coil for effectively evading electromagnetic interference risk, which comprises a secondary high-voltage coil 1, a high-voltage output sheet 2, a coil shell 3, a noise reduction resistor 4, a high-voltage sheath 5 and a spring 6, wherein one end of the high-voltage sheath 5 is detachably and fixedly connected with one end of the coil shell 3, the spring 6 is arranged inside the high-voltage sheath 5 along the length direction, one end of the spring 6 close to the coil shell 3 is fixedly sleeved with one end of the noise reduction resistor 4, the other end of the noise reduction resistor 4 is in contact fit with one end of the high-voltage output sheet 2, the noise reduction resistor 4 is connected with the high-voltage output sheet 2 through the pressure of the spring 6, the other end of the high-voltage output sheet 2 is fixedly connected with one end of the secondary high-voltage coil 1 by welding, the secondary high-voltage coil 1 and the, and the shell 3 is tightly sleeved on the outer side of the noise reduction resistor 4.
The second embodiment is as follows: as shown in fig. 1, this embodiment is further described as an embodiment one, and one end of the high voltage sheath 5 is in interference fit with one end of the coil housing 3.
The utility model discloses the during operation, secondary high-voltage coil 1 produces the high-voltage electricity and flows behind high-voltage output piece 2, release high-pressure electric spark for the spark plug through 6 transfers of resistance 4 of making an uproar of falling, during the release, secondary high-voltage coil 1 produces the LC and vibrates, further produce parasitic current, parasitic current is big more, the electromagnetic wave energy of emitting is big more, be connected through falling resistance 4 of making an uproar between high-voltage output piece 2 and spring 6, parasitic current is after falling resistance 4 of making an uproar of falling and consuming, parasitic current can effectively consume parasitic current, produce electromagnetic wave radiation and reduce in a large number outward, thereby effectively reduce electromagnetic wave energy radiation.
The utility model discloses optimize the structure of the high-pressure output end in the ignition coil high-pressure extension bar, reduce the external electromagnetic energy ripples that sends of ignition coil during operation to accord with electromagnetic compatibility test requirement.
Through using the utility model discloses, can realize the relevant spare part of ignition system of whole car at the during operation, consume parasitic current, reduce the electromagnetic energy ripples, be favorable to complying with the requirement of national standard electromagnetic compatibility.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other forms of embodiment without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
