Abstract
The utility model relates to a shield for an ignition device, which comprises a cover body matched with a high-voltage insulation cover of the ignition device; the center of the cover body is provided with a rectangular through hole; the middle parts of the two long edges of the rectangular through hole are convex arc-shaped edges; the middle parts of the two short edges of the rectangular through hole are concave arc-shaped edges; the cover body is provided with two mounting holes; and the two mounting holes are respectively located at the outer sides of the two concave arc-shaped edges. The edge of the top surface of the cover body is provided with three or more than three grooves, and the grooves are evenly distributed along the edge of the cover body. The top face of the cover body is provided with a boss; the back face of the boss is provided with concave cavity; and the boss is connected between one convex arc-shaped edge and the side face of the cover body. The shield for the ignition device covers on the high-voltage insulation cover of the ignition device and can be well matched with the high-voltage insulation cover to perform a good protection action, thereby, the phenomenon that spark-over breakdown is caused on a high-voltage output end and a low-voltage input end because the high-voltage output end and the low-voltage input end are splashed by water or polluted by oil stain can be prevented, and the service life of the ignition device is effectively prolonged.
Description
Technical field
The utility model relates to a kind of automobile igniter, relates in particular to that arcing punctures, prolongs the ignition mechanism ignition mechanism guard shield in working life between a kind of high low pressure input end that can prevent ignition mechanism.
Background technique
The high-voltage output end of present automobile igniter and low pressure input end all cover in same High-Voltage Insulation, after being contained on the car, this ignition mechanism, influences the working life of ignition mechanism easily because of being spattered by water or being caused that by oil pollution arcing punctures between high-voltage output end and the low pressure input end.
Summary of the invention
After mainly solving original automobile igniter and be contained on the car, the utility model, influences the technical problem in the working life of ignition mechanism easily because of being spattered by water or being caused that by oil pollution arcing punctures between high-voltage output end and the low pressure input end; A kind of ignition mechanism guard shield is provided, and its High-Voltage Insulation that covers on ignition mechanism covers, and plays the effect of protection, can prevent that high-voltage output end and low pressure input end are because of being spattered by water or being caused that by oil pollution arcing punctures, and effectively prolongs the working life of ignition mechanism.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the utility model comprises one and the lid of the High-Voltage Insulation of ignition mechanism lid coupling, described lid center is provided with a through hole, described through hole is rectangle, the middle part on rectangular two long limits is outer convex limit, the middle part of rectangular two minor faces is indent arc limit, described lid is provided with two mounting holes, and described two mounting holes lay respectively at the outside on two indent arc limits.When the utility model is installed on the ignition mechanism, the High-Voltage Insulation that earlier lid is enclosed within ignition mechanism covers, and the middle projection of High-Voltage Insulation lid passes from through hole, and two low-voltage outputs pass from mounting hole, install low pressure wiring nut again, fastening nut is fixed again.Outer convex limit, indent arc limit be arranged so that when the utility model is installed on the ignition mechanism can and the High-Voltage Insulation lid be close to well, keep apart high-voltage output end and low pressure input end, play good protective action, avoid the generation of arcing punch-through between high-voltage output end and the low pressure input end effectively prolonging the working life of ignition mechanism because of being spattered by water or being caused by oil pollution.
As preferably, the edge of the end face of described lid is provided with the groove more than three or three, and described groove is uniform along the lid edge.Be convenient to the installation and removal of lid.
As preferably, the end face of described lid is provided with a boss, and the back side of boss is a cavity, and described boss is connected between the side of a described outer convex limit and lid.Can mate better with the High-Voltage Insulation lid.
As preferably, described lid is that one is injection molded, and described lid adopts PBT G20 plastic material.Easy to make, good insulating properties and fastness are arranged again.
On the lid end face and the position of two mounting hole correspondences also can stamp both positive and negative polarity sign clearly.Get polarity when avoiding installing wrong, use convenient.
The beneficial effects of the utility model are: the High-Voltage Insulation that the utility model covers on ignition mechanism covers, energy and High-Voltage Insulation lid matched well, play good protective action, can prevent that high-voltage output end and low pressure input end are because of being spattered by water or being caused that by oil pollution arcing punctures, and effectively prolongs the working life of ignition mechanism.
