[0002] In the automobile engine ignition system, the ignition coil is an actuator that provides ignition energy for igniting the air and fuel mixture in the engine cylinder.

[0003] A Chinese patent with announcement number CN208885441U discloses an anti-falling automobile ignition coil, comprising a shell, an ignition coil body arranged in the shell, a connector and a connecting pipe, the lower end of the shell is detachably connected to the upper end of the connecting pipe, the lower end of the connecting pipe is detachably installed on the car, the ignition coil body is detachably installed inside the shell through an anti-slip shock-absorbing member, a detachable structure for detachably connecting the two is arranged between an outer wall of the connector and a side wall of the shell, the detachable structure comprises a vertical slot arranged on one side wall of the shell, and a vertical plug which can be inserted into the vertical slot is arranged on a side wall of the connector close to the shell.

[0004] After the vertical plug on the connector of the above structure is inserted into the vertical slot on the shell, a sealant is needed to seal the joint between the two, which results in low efficiency of sealing the connector to the shell and increases the production cost. Utility Model Content

[0005] The utility model aims to solve the problem that after the vertical plug on the prior art connector is inserted into the vertical slot on the shell, it is still necessary to use sealant to seal the joint between the two, which results in low efficiency of sealing the connector to the shell and increases the cost required for production. It reduces the risk of glue leakage at the joint and provides an ignition coil with a low-voltage plug and shell integrated design.

[0006] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0007] An ignition coil with a low-voltage plug and a shell integrally designed comprises a shell and a high-voltage sheath arranged below the shell, a low-voltage plug with a hollow interior and openings at both ends being arranged at one end of the shell, the shell and the low-voltage plug being integrally formed, and a sealing component for sealing the opening of the low-voltage plug being arranged at the opening of the low-voltage plug away from one end of the shell.

[0008] By adopting the above scheme, the shell and the low-voltage plug are formed in one piece, which can save the step of applying glue after the production of the low-voltage plug and the shell is completed, thereby reducing its production cost and improving production efficiency. Providing a sealing component at the opening of the low-voltage plug can reduce the probability of dust and the like entering the low-voltage plug through the opening of the low-voltage plug when it is not used after production, thereby increasing its service life.

[0009] Preferably, the sealing component includes a sealing plate that can cover the opening of the low-pressure plug, and a positioning sealing component is provided between the sealing plate and the opening of the low-pressure plug to position the sealing plate and further improve the sealing between the opening of the low-pressure plug and the sealing plate.

[0010] By adopting the above scheme, the sealing plate can be covered on the opening of the low-pressure plug when the low-pressure plug is not in use, thereby improving the sealing performance between the sealing plate and the low-pressure plug and reducing the probability of dust and the like entering the low-pressure plug when the low-pressure plug is not in use. The positioning sealing component arranged between the sealing plate and the opening of the low-pressure plug can position the sealing plate when the sealing plate covers the low-pressure plug, and can further improve the sealing performance between the sealing plate and the low-pressure plug.

[0011] Preferably, the positioning sealing component includes a positioning groove arranged at one end of the low-voltage plug away from the shell, and a positioning block that can be inserted into the positioning groove is arranged at one end of the sealing plate close to the positioning groove, and after the positioning block is inserted into the positioning groove, the end close to the bottom of the positioning groove abuts against the bottom of the positioning groove.

[0012] By adopting the above scheme, the positioning block arranged on the sealing plate can be inserted into the positioning groove when the sealing plate needs to be installed at the opening of the low-voltage plug, thereby positioning the sealing plate. When the positioning block is inserted into the positioning groove, the end of the positioning block close to the bottom surface of the positioning groove will abut against the bottom of the positioning groove, thereby further improving the sealing performance between the sealing plate and the low-voltage plug and reducing the probability of dust and the like entering the low-voltage plug when the low-voltage plug is not in use.

[0013] Preferably, an anti-drop component for preventing the sealing plate from automatically separating from the low-pressure plug is provided between the sealing plate and the outer surface of the low-pressure plug.

[0014] Preferably, the anti-drop component includes a buckle arranged on the outer surface of the sealing plate, a hook is arranged on the outer surface of the low-pressure plug and engages with the buckle when the sealing plate covers the opening of the low-pressure plug, and an installation component for installing the hook is arranged on the outer wall of the low-pressure plug.

[0015] By adopting the above scheme, the hook arranged on the outer surface of the low-pressure plug can be engaged with the buckle on the outer surface of the sealing plate when the surface of the sealing plate abuts against the open end of the low-pressure plug, thereby reducing the probability of the sealing plate and the low-pressure plug being detached, and the arranged installation component can be used to install the hook.

[0016] Preferably, the mounting component comprises a mounting block protruding from the outer wall of the low-voltage plug, and the mounting block is made of a material with elastic deformation, such as a rubber material.

[0017] By adopting the above scheme, the provided mounting block can be used to install the buckle, and the mounting block is made of a material with elastic deformation properties such as rubber, which can facilitate the buckle engagement of the hook on the mounting block with the buckle on the sealing plate when the sealing plate is covered to the opening of the low-voltage plug. At the same time, due to the elastic deformation property of the mounting block, the mounting block can also drive the hook to retreat when the hook and the buckle are buckled, making the buckle engagement of the hook and the buckle more secure. At the same time, when the distance between the hook and the buckle changes, the hook on the low-voltage plug can still be buckled with the buckle on the sealing plate.

[0018] Preferably, the anti-dropping component is symmetrically arranged on the sealing plate and the outer surface of the low-voltage plug.

[0019] By adopting the above scheme, the anti-detachment components are symmetrically arranged on the outer surface of the sealing plate and the low-pressure plug, which can further reduce the probability of the sealing plate automatically detaching from the low-pressure plug, thereby improving the sealing performance between the low-pressure plug and the sealing plate, and reducing the probability of dust and the like entering the low-pressure plug when the low-pressure plug is not in use.

[0020] The utility model adopts the above technical scheme, which has significant technical effects: the shell and the low-voltage plug are formed in one piece, which can save the step of applying glue after the low-voltage plug and the shell are produced, thereby reducing its production cost and improving production efficiency; and the sealing component is provided at the opening of the low-voltage plug to reduce the probability of dust and the like entering the low-voltage plug through the opening of the low-voltage plug when it is not used after production, thereby improving its service life.

The positioning sealing component includes a positioning groove 5 provided at one end of the low-pressure plug 3 away from the housing 1, and a positioning block 6 that can be inserted into the positioning groove 5 is provided at one end of the sealing plate 4 close to the positioning groove 5. After the positioning block 6 is inserted into the positioning groove 5, the end close to the bottom of the positioning groove 5 abuts against the bottom of the positioning groove 5.

[0031] An anti-slip component is provided between the sealing plate 4 and the outer surface of the low-pressure plug 3 to prevent the sealing plate 4 from automatically separating from the low-pressure plug 3. The anti-slip component is symmetrically arranged on the outer surfaces of the sealing plate 4 and the low-pressure plug 3. The anti-slip component includes a buckle 8 provided on the outer surface of the sealing plate 4, and a hook 7 is provided on the outer surface of the low-pressure plug 3 to engage with the buckle 8 when the sealing plate 4 covers the opening of the low-pressure plug 3.
