Abstract
The utility model discloses a high-efficient radiating spark plug high-voltage cap belongs to power accessories technical field, and high-voltage cap suit is outside in the spark plug, and high-voltage cap includes external shielding shell and inside rubber structure, its characterized in that, the cooperation of external shielding shell tip and spark plug outer lane distributes a plurality of louvres on the external shielding shell. Compared with the prior art have quick heat dissipation, the characteristics of protection rubber sleeve.
Description
Technical Field
The utility model relates to an electric power accessory technical field especially belongs to a high-efficient radiating spark plug high-voltage cap.
Background
The high-voltage cap is a terminal part output by a high-voltage igniter, is an important part for clamping a high-voltage wire on the tail section of a spark plug, and has the functions of connecting the high-voltage wire with the spark plug, conducting high-voltage electricity and isolating high-frequency radiation. When the spark plug is used, the high-pressure cap is sleeved on the spark plug, the outer ring of the spark plug is clamped by the external shielding shell, the outer ring of the spark plug is in threaded connection with the cylinder head, and the external shielding shell plays a role in grounding at the same time. The high-voltage cap is internally provided with a rubber sleeve for wrapping the spark plug, and the deepest part of the rubber sleeve is in contact with the tail section of the spark plug to conduct high-voltage current. The heat of the cylinder head reaches the high-pressure cap through the transfer of the spark plug, so that the high temperature inside the high-pressure cap is caused, the high-temperature aging of the rubber material inside the high-pressure cap is caused, and the problems of poor ignition of the spark plug and the like are caused.
When an engine runs, the spark plug transfers the heat of the cylinder head to the high-pressure cap, and a shielding shell outside the high-pressure cap is made of metal and directly contacts with air, so that the high-pressure cap dissipates heat quickly and is not too high in temperature. However, the rubber inside the high-pressure cap has slow heat conduction due to the material characteristics, and a large amount of heat is accumulated at the rubber material, so that the high-pressure cap is easy to age at high temperature and crush and crack rubber, and the rubber material has good quality, so that the high-pressure cap is easy to contact poorly and even short-circuit, and potential safety hazards are caused.
Disclosure of Invention
An object of the utility model is to provide a high-efficient radiating spark plug high-pressure cap promptly to reach the purpose of quick heat dissipation, protection rubber sleeve.
The utility model provides a high-efficient radiating spark plug high-voltage cap, high-voltage cap suit are in the spark plug outside, and high-voltage cap includes external shield shell and inside rubber structure, its characterized in that, external shield shell tip and spark plug outer lane cooperation distribute a plurality of louvres on the external shield shell.
Further, the external shield shell is formed in an integrated or split type.
Furthermore, a plurality of heat dissipation holes are uniformly distributed on the external shielding shell.
Furthermore, a plurality of radiating holes are uniformly distributed on the outer shielding shell close to the outer ring of the spark plug.
Furthermore, a plurality of heat dissipation holes are uniformly distributed at the bottom of the external shielding shell.
The utility model provides a high-efficient radiating spark plug high-voltage cap during the use, has and accelerates the outside flow of hot-air to reduce the inside rubber materials temperature of high-voltage cap, reach the positive effect that improves high-voltage cap life.
Drawings
The accompanying drawings partially disclose embodiments of the present invention, in which,
fig. 1 is a schematic structural diagram of an application state of the present invention;
fig. 2 is a schematic diagram of the shielding case structure of the present invention.
Detailed Description
The present invention will be further described with reference to the following examples and accompanying drawings.
As shown in FIG. 1, the utility model provides a high-pressure cap of spark plug of high-efficient radiating, high-pressure cap suit are in 3 outsides of spark plug, and high-pressure cap includes external shield shell 1 and inside rubber structure, its characterized in that, the cooperation of external shield shell 1 tip and 3 outer lanes of spark plug, a plurality of louvres 2 distribute on the external shield shell 1.
In a specific embodiment, as shown in fig. 1-2, the high-voltage cap is sleeved outside the spark plug 3, the end of the external shielding shell 1 is matched with the outer ring of the spark plug 3, and a plurality of heat dissipation holes 2 are uniformly distributed on the external shielding shell 1 near the outer ring and at the bottom of the spark plug 3. The hot air in the shell can flow outwards, the temperature of the rubber material in the shell can be effectively reduced, and the service life of the high-voltage cap is prolonged.
It should be noted that while the invention has been described in detail with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various obvious changes can be made therein without departing from the spirit and scope of the invention.
