Description

Technical Field

[0001] The utility model relates to the technical field of automobile ignition coils, in particular to a small-volume plug-in automobile ignition coil. Background Art

[0002] An ignition coil is an actuator that provides ignition energy for igniting the air and fuel mixture in the engine cylinder. After searching, the Chinese patent authorization number CN219226049U discloses an anti-drop automobile ignition coil, which includes an ignition coil body, one end of which is fixedly connected to a plug connector, a built-in groove is provided inside the top of the plug connector, the built-in groove is connected to a rubber plate through a reset spring, a buckle column is provided on one side of the upper surface of the rubber plate, and the buckle column is connected to an electrical connector through a jack. The utility model effectively increases the friction between the plug connector and the electrical connector, and can limit the position of the electrical connector on the plug connector, avoiding the phenomenon of poor contact caused by loosening between the electrical connector and the plug connector, and improving the stability of the automobile ignition coil during the power connection process. However, when the device is in use, due to the cooperation between the rubber plate and the buckle column, even when the rubber plate is pressed down and reaches the maximum movement range during connection, it can only be level with the inner wall of the terminal block, and the position of the buckle column itself is higher than that of the rubber plate. Therefore, when the connection is made, after the position of the rubber plate moves downward, the buckle column still needs to be manually pressed down to enter the interior of the terminal block. Therefore, the device is not only inconvenient during connection, but also makes it more convenient to disassemble. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example 1: Please refer to Figure 1-5The embodiment of the utility model provides a small-volume plug-in automobile ignition coil, including an electric head 1 and an ignition coil body 2. A support plate 7 is fixedly installed at the bottom of the electric head 1, and a fixing box 8 is fixedly installed on the bottom surface of the support plate 7. A limited wedge 11 is symmetrically slidably connected inside the support plate 7. The bottom of the limited wedge 11 is inside the fixing box 8, and a tension spring 12 is symmetrically fixedly installed at the bottom of the limited wedge 11. A support frame 3 is fixedly installed on the top surface of the oil tank of the support plate 7. A limited frame 4 is arranged on the left side of the support frame 3. The internal size of the limited frame 4 is the same as that of the ignition coil. The size of the main body 2 matches, and the side walls of the fire coil main body 2 are fixedly installed with limiting columns 5, so that when the fire coil main body 2 is connected to the inside of the power supply head 1, the fire coil main body 2 passes through the inside of the support frame 3 and penetrates the inside of the limiting frame 4. The limiting frame 4 can be easily moved with it through the limiting columns 5. At the same time, when the fire coil main body 2 moves, the position of the limiting wedge 11 can be easily moved downward. When the fire coil main body 2 is connected, the limiting wedge 11 rises due to the action of the tensioning spring 12, which can limit the position of the fire coil main body 2.

[0020] Embodiment 2: In this embodiment, as Figure 1-5 As shown, movable holes 9 are provided inside the side walls on both sides of the fixed box 8, and a lever 10 is provided inside the fixed box 8. The lever 10 passes through the interior of the limiting wedge 11 and is fixedly connected to the interior of the limiting wedge 11. Both ends of the lever 10 pass through the outside of the movable hole 9. When the fire coil body 2 is disassembled, the lever 10 is pressed downward to move the position of the limiting wedge 11 downward so that it can completely enter the interior of the fixed box 8, thereby pulling the limiting frame 4 or the fire coil body 2 outward to conveniently take out the fire coil body 2.

[0021] Embodiment 3: In this embodiment, as Figure 1-5 As shown, movable grooves 13 are symmetrically arranged inside the side walls of the top surface of the support plate 7, and sliders 14 are symmetrically fixedly installed on the bottom surface of the limit frame 4. The sliders 14 are slidably connected to the inside of the movable grooves 13 through the limit frame 4. Reset springs 6 are fixedly installed on both sides of the support frame 3, and the reset springs 6 are fixedly connected to the right side wall of the limit frame 4. When the fire coil body 2 is taken out, the position of the limit frame 4 can be easily reset through the reset spring 6, and the internal size of the support frame 3 matches the size of the fire coil body 2.

[0022] It should be noted that in this embodiment, when a small plug-in automobile ignition coil is used, Figure 1-5As shown, when the fire coil body 2 is connected to the interior of the power connector 1, the fire coil body 2 passes through the interior of the limit frame 4 through the interior of the support frame 3, and the limit frame 4 can be easily moved with it through the limit column 5. At the same time, when the fire coil body 2 moves, the position of the limit wedge 11 can be easily moved downward. When the fire coil body 2 is connected, the limit wedge 11 rises due to the action of the tensioning spring 12, and the position of the fire coil body 2 can be limited. When the fire coil body 2 is disassembled, the lever 10 is pressed downward to move the position of the limit wedge 11 downward so that it can completely enter the interior of the fixed box 8, thereby pulling the limit frame 4 or the fire coil body 2 outward to easily take out the fire coil body 2. When the fire coil body 2 is taken out, the position of the limit frame 4 can be easily reset through the reset spring 6.
