Detailed Implementation

[0036] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are partial embodiments of this utility model, not complete embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] like Figure 1 - Figure 6 As shown, one embodiment of the present invention provides a connection assembly for a high-voltage coil and a low-voltage socket, including a high-voltage frame, a low-voltage frame, and a plug component connected to the low-voltage socket.

[0038] The insert component includes a second insert 2 and two first inserts 1;

[0039] The low-voltage frame is provided with a first limiting groove structure 3 for accommodating the end of the low-voltage coil;

[0040] The high-voltage frame is provided with a second limiting groove structure for limiting the pin 4 connected to the end of the high-voltage coil;

[0041] The first insert 1 is inserted into the first limiting groove structure 3 and connected to the end of the low voltage coil;

[0042] The second insert 2 is inserted into the second limiting groove structure and connected to the insert pin 4.

[0043] The first limiting groove structure 3 set on the low-voltage frame can accommodate the end of the low-voltage coil into the first limiting groove structure 3. The first plug 1 of the low-voltage socket is inserted into the first limiting groove structure 3 and connected to the end of the low-voltage coil. The second limiting groove structure sets the pin 4 connected to the end of the high-voltage coil to be limited. The second plug 2 on the high-voltage socket is inserted into the second limiting groove structure and contacts the pin 4. This detachable connection method realizes the connection between the low-voltage socket and the ignition coil, replacing the traditional welding method. This avoids poor contact caused by incomplete welding or missing welding, resulting in better stability and not affecting the correct signal transmission between the high-voltage and low-voltage coils and the low-voltage socket.

[0044] In addition, it is easier to disassemble and assemble, making it more convenient to maintain, and it can be reused, making it more practical.

[0045] According to one embodiment of the present invention, such as Figure 1 As shown, the low-voltage frame includes a winding post 7, a connector 8, and two limiting blocks 9 connected together.

[0046] The winding post 7 is located inside the high-voltage frame, the low-voltage coil is wound on the winding post 7, the connector 8 is connected to the end of the winding post 7, and two limiting blocks 9 are respectively connected to both sides of the connector 8.

[0047] The first limiting groove structure 3 includes two cross-shaped grooves, and each limiting block 9 has a cross-shaped groove.

[0048] It should be noted that the winding post 7, the connector 8, and the limiting block 9 are integrally formed.

[0049] According to one embodiment of the present invention, such as Figure 1 As shown, the cross-shaped groove includes a first groove 301 and a second groove 302, which are connected to each other. The end of the low-voltage coil is limited within the first groove 301.

[0050] The first insert 1 is inserted into the second groove 302.

[0051] Since the second groove 302 is used to insert the first plug 1 and fix the first plug 1 in place, and the first groove 301 accommodates the wire of the low voltage coil, the length direction of the first plug 1 and the wire direction of the low voltage coil located in the second groove 302 intersect. Even if the wire of the low voltage coil moves in the second groove 302, it can fully contact the end of the first plug 1, thereby making the connection between the ignition coil and the low voltage socket more stable and less prone to poor contact.

[0052] Preferably, the length directions of the first groove 301 and the second groove 302 are the same.

[0053] According to one embodiment of the present invention, a low-voltage socket includes a base, one end of a first insert 1 and a second insert 2 are connected to the base, and the length direction of the first insert 1 and the length direction of the second insert 2 are the same.

[0054] The first insert 1 and the second insert 2 are rigid inserts, which are not easily deformed or damaged even after multiple insertions, making them more practical.

[0055] The length direction of the first insert 1 is the same as the depth direction of the first limiting groove structure 3. It should be noted that when the first insert 1 is inserted into the first groove 301 and is in place, the second insert 2 is connected to the pin 4.

[0056] According to one embodiment of the present invention, the depth of the first groove 301 is less than the depth of the second groove 302.

[0057] By setting the depth of the first groove 301 to be less than the depth of the second groove 302, after the first insert 1 is inserted into place, it can be fully clamped in the middle with the wire body at the end of the low voltage coil under the action of the bottom wall of the first groove 301 and the first insert 1, thus fully abutting against the first insert 1, thereby making the stability better.

[0058] According to one embodiment of the present invention, a first slot 101 is provided on the first insert 1, and the end of the low voltage coil is engaged in the first slot 101.

[0059] Because of the first slot 101, the wire at the end of the low-voltage coil is engaged in the first slot 101, so that all three side walls of the first slot 101 can contact the low-voltage coil, the contact area between the low-voltage coil and the first insert 1 is larger, and the contact stability is better.

[0060] According to one embodiment of the present invention, the first groove 301 includes a connected figure-eight groove and a straight groove. The figure-eight groove and the straight groove are arranged along the length direction of the first groove 301, and the diameter of the figure-eight groove near the straight groove is smaller than the diameter of its other end.

[0061] The figure-eight groove allows for easy insertion of the end of the low-voltage coil into the straight groove. The diameter of the straight groove is smaller than the diameter of the low-voltage coil, which helps to limit the movement of the low-voltage coil wire.

[0062] According to one embodiment of the present invention, the high-pressure frame includes a top plate, and the second limiting groove structure includes a first slot 6 opened on the top plate and a second slot 10 opened on the side wall of the top plate. The second slot 10 is connected to the first slot 6, and the pin 4 is engaged in the second slot 10.

[0063] The second insert 2 is inserted into the first slot 6 and connects with the pin 4.

[0064] A wire passage groove 11 is provided on the side wall of the top plate, which is connected to the second slot 10. After the pin 4 is connected to the end of the high-voltage coil, the part of the high-voltage coil wire close to the pin 4 is located in the wire passage groove 11. This can support the part of the high-voltage coil wire, protect the wire of the high-voltage coil, and prevent the pin 4 from being dragged by the high-voltage coil wire. This also makes it less likely for the contact position between the pin 4 and the second plug 2 to have a loose connection, thus improving the stability of the connection between the ignition coil and the low-voltage socket.

[0065] According to one embodiment of the present invention, a second slot 201 is provided on the second insert 2, and the end of the insert pin 4 is engaged in the second slot 201.

[0066] The second slot 201 allows the pin 4 to be inserted into the second slot 201, thereby increasing the contact area between the pin 4 and the second slot 201 and improving the snap-fit ​​stability, making it less prone to poor contact.

[0067] According to one embodiment of the present invention, such as Figure 6 As shown, the first slot 6 includes a first slot 601, a second slot 602 and a third slot 603 connected in sequence. The width of the first slot 601 and the width of the third slot 603 are the same. The width of the first slot 601 is adapted to the thickness of the second insert 2. The width of the second slot 602 is greater than the width of the first slot 601.

[0068] Furthermore, inclined grooves are provided on the side walls of the first groove 601 and the third groove 603, which can guide the second pin 4.

[0069] The distance between the opposite sidewalls of the first slot 601 and the third slot 603 is adapted to the width of the second insert 2, further improving the stability of the second insert 2 when inserted into the first slot 6.

[0070] The second slot 10 includes a socket and a fourth slot. One side of the second slot 602 is connected to the socket, and the other side is connected to the fourth slot. The pin 4 passes through the socket and is inserted into the second slot 602, and the end of the pin 4 enters the fourth slot, locking the end of the pin 4 into the fourth slot and limiting the pin 4. The second insert 2 has two ends after opening the second slot 201. The two ends are respectively inserted into the first slot 601 and the third slot 603. The second slot 201 is inserted into the pin 4 in the second slot 602. The pin 4 and the second insert 2 are both fixed in the second limiting slot structure, and the insertion of the pin 4 and the second insert 2 further fixes them, thereby making the overall stability better, reducing the likelihood of loose connection, and reducing the occurrence of poor contact.

[0071] According to one embodiment of the present invention, such as Figure 3 and Figure 4 As shown, a concave block 12 is provided on the high-voltage frame, and a limiting block 9 is inserted into the concave block 12.

[0072] With the concave block 12 and the limiting block 9, the high-voltage frame and the low-voltage frame can be quickly assembled, so that the first plug 1 and the second plug 2 on the low-voltage socket can quickly align with the first groove 301 and the second limiting groove respectively, and the position is not easily offset, making the assembly faster and more convenient.

[0073] Among them, the first insert 1 is a low-voltage insert, and the second insert 2 is a high-voltage insert.
