Description

Technical Field

[0001] This utility model relates to the field of ignition coil installation technology, specifically to an automotive ignition coil with a reinforced structure. Background Technology

[0002] The main function of an automotive ignition coil is to convert the low voltage (usually 12 volts) provided by the vehicle battery into a high voltage (usually tens of thousands of volts) to generate a spark that ignites the fuel mixture in the engine cylinder. The ignition coil works by electromagnetic induction, converting low-voltage electricity into high-voltage electricity to ensure normal engine operation and smooth combustion. After the spark plugs are installed in place, the ignition coil is installed on top of the spark plugs. Then, the spark plugs are locked with bolts, and the ignition coil is connected to the wiring harness.

[0003] Because of the significant vibrations in the engine compartment during vehicle operation, the connectors of the wiring harness and the socket of the ignition coil are prone to loosening due to vibration over long-term use. Therefore, a reinforced structure is needed to strengthen the connection between the two. Thus, we propose an automotive ignition coil with a reinforced structure. Summary of the Invention

[0004] The purpose of this utility model is to provide an automotive ignition coil with a reinforced structure. By setting a reinforcing plate, it can be installed and locked above the coil body. After the wire harness plug is inserted into the socket, the reinforcing plate is locked, so that the bottom stop bar abuts against the side of the wire harness plug to limit its position. During use, it prevents the wire harness plug from slipping out of the socket of the coil body due to vibration, thus providing a reinforcing function and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automotive ignition coil with a reinforced structure, comprising a coil body and a reinforcing plate. The socket of the coil body is located at a position slightly above its side. A screw hole is provided on the surface of the coil body on the side of the socket. The side of the reinforcing plate is in contact with the surface of the coil body on the side of the socket. A through-hole is provided on the side of the reinforcing plate, which is aligned with the screw hole. A locking bolt is screwed into the screw hole through the through-hole to lock the reinforcing plate. Side plates are provided on the surface of the coil body on both sides of the reinforcing plate. The side plates are in contact with the side surface of the reinforcing plate. A stop strip is fixed to the bottom of the reinforcing plate at the end away from the locking bolt.

[0006] By adopting the above technical solution, after the spark plug and ignition coil are installed in place and locked with bolts, the plug of the wiring harness is inserted into the socket, and then the reinforcing plate is locked above the coil body, and the stop bar is placed on the side of the wiring harness plug to limit it. This can prevent the plug from being vibrated and loosening from the socket when the car is working.

[0007] Optionally, the opening is elongated. When different positions of the elongated opening are aligned with the screw holes, the position of the reinforcing plate can be adjusted left and right to adjust the left and right position of the baffle.

[0008] Optionally, the opening is circular, and the baffle can be adjusted left and right at the bottom of the reinforcing plate.

[0009] By adopting the above technical solution, the left and right positions of the retaining strip can be adjusted without adjusting the left and right positions of the reinforcing plate.

[0010] Optionally, two parallel horizontal openings are provided on the surface of the reinforcing plate above the baffle. Vertical screws are fixed on both sides above the baffle, passing through the horizontal openings and extending to the top of the reinforcing plate. Locking nuts are screwed onto the outer ring of the screws, which abut against the surface of the reinforcing plate, so that the baffle can be adjusted and locked at the bottom of the reinforcing plate.

[0011] By adopting the above technical solution, the left and right positions of the stop bar can be adjusted by using the screw to slide left and right within the horizontal opening and locking it.

[0012] Optionally, a first rubber pad is attached and fixed to the inner surface of the coil body of the side plate, and two first rubber pads are provided.

[0013] By adopting the above technical solution, when the reinforcing plate is locked onto the surface of the coil body, anti-slip properties are achieved for the left and right positions of the reinforcing plate.

[0014] Optionally, a second rubber pad is fixedly attached to the surface of the baffle, and the second rubber pad is located on the surface of the baffle between the screws.

[0015] By adopting the above technical solution, after the screw is tightened and locked by the locking nut, the stop bar abuts against the bottom surface of the reinforcing plate through the second rubber pad to avoid sliding.

[0016] Optionally, the outer dimensions of the locking nut are the same as the nut dimensions of the locking bolt.

[0017] By adopting the above technical solution, the wrench used to tighten the lock nut and the lock bolt can be used interchangeably.

[0018] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0019] 1. The technical solution of this application provides a reinforcing plate that can be installed and locked above the coil body. After the plug of the wire harness is inserted into the socket, the reinforcing plate is locked so that the bottom stop bar abuts against the side of the wire harness plug to limit its movement. During use, this prevents the plug of the wire harness from slipping out of the socket of the coil body due to vibration, thus providing a reinforcing function.

[0020] 2. The technical solution of this application fixes side plates on both sides of the coil body surface of the reinforcing plate. The side plates are in contact with the side of the reinforcing plate to prevent its rotation angle. The anti-rotation locking of the reinforcing plate can be achieved by using only one locking bolt.

[0021] 3. The technical solution of this application can prevent the reinforcing plate from sliding when the first rubber pad is attached to the surface of the coil body on the side of the screw hole and the reinforcing plate is adjusted to the correct position and locked by the locking bolt.

[0022] 5. The technical solution of this application has a second rubber pad attached and fixed to the upper surface of the stop bar between the screws. When the stop bar is locked and abuts against the lower surface of the reinforcing plate, it can have a good anti-slip effect. Attached Figure Description

[0029] Please see Figure 1 and Figure 2This utility model provides a technical solution: an automotive ignition coil with a reinforced structure, including a coil body 1 and a reinforcing plate 3. The socket 2 of the coil body 1 is located on its upper side. The detailed internal structure of the coil body 1 and how the socket 2 connects to the internal structure of the coil body 1 are existing known technologies. This application does not change its structure, so its internal structure and principle will not be further described. In addition, a through-hole is provided on the side of the coil body 1 for a nut to pass through and lock the coil body 1 above the spark plug. The following mainly describes the reinforcement structure for connecting the coil body 1 to the automotive wiring harness.

[0030] After the coil body 1 is installed in place, the plug of the automotive wiring harness is first inserted into the socket 2. A screw hole 12 is provided on the surface of the coil body 1 on the side of the socket 2, and the left side of the reinforcing plate 3 is in contact with the surface of the coil body 1 on the side of the socket 2. A stop strip 31 is fixed to the bottom right side of the reinforcing plate 3. A through hole 32 is provided on the left side of the reinforcing plate 3, which is vertically through and aligned with the screw hole 12. In use, the through hole 32 on the left side of the reinforcing plate 3 can be slid left and right to adjust its position so that it is aligned with the screw hole 12 at different positions. Changing the left and right position of the reinforcing plate 3 will change the left and right position of the stop strip 31. Adjustment ensures that the stop strip 31 is in the right position of the wiring harness plug and in contact with it. Then, the locking bolt 321 is passed through the through hole 32 and screwed into the screw hole 12 to lock the reinforcing plate 3, so that the stop strip 31 is always in the right position of the wiring harness plug and is limited, preventing the wiring harness plug from loosening and sliding out of the socket 2 due to vibration.

[0031] When a single locking bolt 321 is used to lock the reinforcing plate 3, the reinforcing plate 3 is prone to rotating left and right and cannot be locked. In order to solve this problem, side plates 11 are provided on the surface of the coil body 1 on both sides of the reinforcing plate 3. The side plates 11 are in contact with the side surface of the reinforcing plate 3. When the locking bolt 321 locks the reinforcing plate 3, the reinforcing plate 3 will not rotate and cannot be locked.

[0032] Additionally, a first rubber pad 13 is attached and fixed to the surface of the coil body 1 on the inner side of the side plate 11. There are two first rubber pads 13. When the locking bolt 321 is tightened and the reinforcing plate 3 is pressed down, the first rubber pad 13 presses against the bottom surface of the reinforcing plate 3, which can prevent the reinforcing plate 3 from sliding left and right after locking. Example

[0033] This application also provides another embodiment to adjust the left and right positions of the stop bar 31. While keeping all other structures the same as in Embodiment 1, the following changes and structural additions are made. Please refer to [link / reference]. Figure 3 and Figure 4The through-hole 32 is circular, and two parallel horizontal openings 33 are opened on the surface of the reinforcing plate 3 above the baffle 31. Vertical screws 311 are fixed on both sides above the baffle 31, passing through the horizontal openings 33 to the top of the reinforcing plate 3. When the screws 311 slide left and right in the horizontal openings 33, the baffle 31 can be adjusted left and right at the bottom of the reinforcing plate 3. A locking nut 312 is screwed onto the outer ring of the screw 311. After the wire harness plug is inserted into the socket 2, the locking bolt 321 is directly inserted through. After passing through the opening 32, tighten it into the screw hole 12 to lock the reinforcing plate 3. This allows the stop bar 31 to slide to the left under the reinforcing plate 3. At the same time, the screw rod 311 also slides to the left in the horizontal opening 33. When the stop bar 31 just touches the right side of the wire harness plug, tighten the locking nut 312 to press it against the surface of the reinforcing plate 3, thereby locking the position of the stop bar 31. Similarly, the stop bar 31 is always placed on the right side of the wire harness plug to limit its position and prevent the wire harness plug from loosening and sliding out of the socket 2 due to vibration.

[0034] A second rubber pad 313 is also attached and fixed to the surface of the baffle 31. The second rubber pad 313 is located on the surface of the baffle 31 between the screws 311. When the locking nut 312 is tightened and pressed against the surface of the reinforcing plate 3, the baffle 31 is pressed against the bottom surface of the reinforcing plate 3 through the second rubber pad 313, which can prevent the baffle 31 from sliding left and right.

[0035] Furthermore, the outer dimensions of the locking nut 312 are the same as the nut dimensions of the locking bolt 321, making the wrenches for tightening the locking nut 312 and the locking bolt 321 interchangeable.

[0036] In use, first loosen the locking bolt 321 to remove the reinforcing plate 3. After the spark plug and coil body 1 are installed in place, first connect the wire harness to the coil body 1 by inserting the plug into the socket 2. Then place the reinforcing plate 3 over the plug of the wire harness and make the end of the reinforcing plate 3 containing the through hole 32 touch the upper surface of the coil body 1 between the side plates 11, and align the through hole 32 with the screw hole 12. When using Embodiment 1, the reinforcing plate 3 is pushed to the left so that the stop bar 31 is exactly against the right side surface of the wire harness socket 2. At this time, the elongated through-hole 32 is still aligned with the screw hole 12, allowing the locking bolt 321 to pass through the through-hole 32 and be tightened into the screw hole 12, thereby locking the reinforcing plate 3. When using Embodiment 2, the locking bolt 321 is first directly passed through the through-hole 32 and tightened into the screw hole 12, thereby locking the reinforcing plate 3. Then, the locking nut 312 is loosened, allowing the stop bar 31 to slide to the left under the reinforcing plate 3. At this time, the screw rod 311 also slides to the left in the horizontal opening 33 until the stop bar 31 is exactly against the right side of the wire harness plug. Then, the locking nut 312 is tightened, thereby locking the position of the stop bar 31. This ensures that the stop bar 31 is always positioned on the right side of the wire harness plug and is limited, preventing the wire harness plug from slipping out of the socket 2 due to vibration.
