Description

Combined pen-type ignition coil

Technical Field

The utility model relates to an ignition coil on an engine, in particular to a combined pen-type ignition coil.

Background

The ignition coil is inserted into the cylinder hole of automobile engine and is broken down by the spark plug in the cylinder to ionize air and generate electric spark, and it repeatedly stores and discharges energy at different frequencies according to different rotation speeds of the engine

Because the existing ignition coil is independently inserted on the cylinder in a pen-shaped manner, the installation efficiency is low, and then the combined ignition coil is adopted, the sealing performance of the shell of the combined ignition coil is poor, water is easy to enter when the engine is cleaned, the water entering of the circuit board is invalid, and meanwhile, after the combination, gaps are easy to appear in connection between the plug bush and the shell, the matching is not tight, the installation sealing performance of the shell is poor, and electric leakage is easy to occur.

Disclosure of Invention

In order to solve the problems, the utility model aims to provide the combined pen-type ignition coil which is strict and reliable in structure, thereby having waterproof performance and anti-creeping performance.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a combination pen-holder type ignition coil, includes injection moulding's integrated into one piece's casing, establish the mounting groove on the casing install electronic module and fill in with epoxy filling in the mounting groove, be equipped with four installation pipes of arranging in proper order on the casing, dispose the location inserted bar between the installation pipe, the installation pipe is used for installing high-pressure output part, high-pressure output part includes installation intraductal male iron core, low-pressure pipe and high-pressure pipe, and the iron core is inserted and is established in the low-pressure pipe, and the low-pressure pipe outer wall round joint has low-voltage coil, and the round joint has high-pressure coil in the high-pressure pipe, and the rubber plug bush is established to the high-pressure coil overcoat, and this rubber plug bush's one end is contacted with the installation pipe to be equipped with annular sealing ring cover in this end, still be equipped with the insulating ring of arranging in proper order on the peripheral wall of rubber plug bush near sealing ring cover the high-pressure head seat the high-pressure head is last to be disposed with high-pressure head, high pass wire and high-pressure coil connection, the high pressure head.

The peripheral wall of the insertion end of the rubber plug bush is conical.

The beneficial effects of the utility model are as follows: the integrated into one piece's casing and fill up through epoxy's filling, the installation pipe that the casing extends simultaneously can prevent effectively that water from getting into in the casing, and the sealing ring cover on the rubber plug bush can cover the open end at the cylinder hole, can prevent effectively that high-voltage electricity from leaking, and the location inserted bar can make the installation location reliable, improves the efficiency of installation, just so has reached the tight reliable technological effect of structure, possesses waterproof performance and anticreep simultaneously.

The utility model is further described below with reference to the drawings and detailed description.
