[0035] like Figures 1 to 4 As shown, this utility model provides a high-voltage frame, including a frame cylinder 100, a baffle mechanism, and a positioning mechanism; the baffle mechanism includes an annular assembly and an anti-creep assembly, the annular assembly is disposed on the outer wall of the frame cylinder 100 and is spaced apart along the height direction of the frame cylinder 100, and the anti-creep assembly is disposed at the bottom of the frame cylinder 100; the annular assembly has an opening 201, and the openings 201 are staggered along the height direction of opposite sides of the frame cylinder 100; the anti-creep assembly has a guide groove 301, and the positioning mechanism is respectively disposed at the top and bottom of the frame cylinder 100 for assembly with a low-voltage coil.
[0036] In this embodiment, the high-voltage frame includes a frame cylinder 100, a baffle mechanism, and a positioning mechanism. The baffle mechanism includes an annular assembly and an anti-creep component. The annular assembly is spaced along the height direction of the frame cylinder 100, and openings 201 are staggered along the height direction of opposite sides of the frame cylinder 100. This prevents the coil turns from breaking down and the voltage distribution from uneven due to the alternation of high and low voltages, ensuring that the voltage in the ignition coil is evenly distributed from high to low. An anti-creep component is also provided at the bottom of the frame cylinder 100. The anti-creep component has a guide groove 301, which can create a channel for epoxy resin and allow it to vent. This effectively prevents creepage, improves the insulation performance of the coil, and enhances the stability and safety of operation. When assembled, the positioning component can be assembled with the upper and lower ends of the low-voltage coil to ensure the assembly of the high and low voltage coils.
[0037] According to one embodiment provided by this utility model, such as Figure 1 , Figure 2 and Figure 4 As shown, the anti-creep component includes an anti-creep baffle 300, which is located at the bottom of the skeleton cylinder 100 and is arranged along the circumference of the skeleton cylinder 100.
[0038] Furthermore, such as Figure 4 As shown, the anti-creep barrier 300 is provided with four guide grooves 301, which are symmetrically distributed along the four vertices of the skeleton cylinder 100.
[0039] In this embodiment, an anti-creeping baffle 300 is installed on the bottom end face of the skeleton cylinder 100, which can effectively prevent the high voltage skeleton from creeping through to the low voltage and the internal iron core when it is installed and put into use.
[0040] Preferably, guide grooves 301 with a width of 3.5mm are opened at the four vertices of the anti-creep baffle 300 corresponding to the skeleton cylinder 100. The guide grooves 301 can create a channel for epoxy resin and also provide an exhaust channel for epoxy resin, so as to improve the quality of epoxy resin solidification.
[0041] According to one embodiment provided by this utility model, such as Figure 1 and Figure 2 As shown, the annular assembly includes annular groove baffles 200, which are evenly distributed along the outer wall of the skeleton cylinder 100 from top to bottom.
[0042] Furthermore, there are seven annular groove baffles 200, which are evenly distributed along the top and bottom of the outer side wall of the skeleton cylinder 100, and each annular groove baffle 200 is provided with an opening 201.
[0043] In this embodiment, seven annular groove baffles 200 are evenly connected to the outer wall of the skeleton cylinder 100. Preferably, the wall thickness of the annular groove baffles 200 is 0.8mm, and each annular groove baffle 200 has an opening with a width range of 1.4mm-2mm. This can effectively prevent the cross-connection phenomenon between the high and low voltage coils during installation, and at the same time improve the uniformity of the voltage distribution between the high voltage coil turns.
[0044] An opening 201 is designed on each annular wire groove baffle 200 to prevent reverse winding of the wire. The openings 201 of adjacent annular wire groove baffles 200 are staggered and symmetrically designed along the two opposite sides of the skeleton cylinder 100, which ensures a small voltage difference between coil turns, reduces the mutual breakdown between coil turns, and provides a strong guarantee for the stable operation of the ignition system.
[0045] According to one embodiment provided by this utility model, such as Figure 1 and Figure 2 As shown, the width of the opening 201 is adapted to the width of the cable to be bypassed.
[0046] In this embodiment, preferably, the width of the opening 201 is adapted to the width of the cable to be bypassed, so that the conversion of each grade can be completed through the opening 201. After the cable is wound, the end is soldered. The width of the opening 201 being adapted to the width of the cable to be bypassed makes it easier for the cable to pass through.
[0047] According to one embodiment provided by this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, the positioning mechanism includes a positioning block assembly, which is located on the top surface of the skeleton cylinder 100 and is used to assemble with the top of the low-voltage coil.
[0048] In this embodiment, the positioning mechanism includes a positioning block assembly. Preferably, the positioning assembly is disposed on the upper end face of the skeleton cylinder 100, that is, the top outer surface. In use, the positioning block assembly is assembled with the top of the low-voltage coil installed inside the skeleton cylinder 100 to achieve the effect of fixing the low-voltage coil.
[0049] According to one embodiment provided by this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, the positioning block assembly includes a first positioning block 400, which is elongated.
[0050] In this embodiment, the positioning block assembly includes a first positioning block 400, wherein, preferably, the first positioning block 400 is strip-shaped, and the first positioning block 400 is the winding start pin 403 of the high-voltage skeleton.
[0051] Optionally, the first positioning block 400 can also be a strip shape or other easy-to-use shape, which does not deviate from the design concept of this utility model and should fall within the protection scope of this utility model.
[0052] According to one embodiment provided by this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, the positioning block assembly also includes a second positioning block 401, which is symmetrically arranged on both sides of the top surface of the skeleton cylinder 100.
[0053] In this embodiment, the positioning block assembly further includes a second positioning block 401. Preferably, there are two second positioning blocks 401, distributed on both sides of the first positioning block 400. Both the first positioning block 400 and the second positioning block 401 are provided with matching low-voltage coils to complete the assembly of the top of the low-voltage coil with the skeleton cylinder 100.
[0054] According to one embodiment provided by this utility model, such as Figure 1 , Figure 2 and Figure 4 As shown, the positioning mechanism also includes a positioning plate 402, which is located at the bottom of the skeleton cylinder 100 and is used to assemble with the bottom end of the low-voltage coil.
[0055] In this embodiment, the positioning mechanism further includes a positioning plate 402, which is disposed on the lower end face of the skeleton cylinder 100, i.e., the bottom outer surface. The two bottom baffle notches at the lower end of the low-voltage coil engage with the positioning plate 402 and are then engaged with the positioning block and the low-voltage coil to complete the assembly of the high-voltage and low-voltage coils. The cooperative use of the first positioning block 400, the second positioning block 401, and the positioning plate 402 ensures the centered positioning of the low-voltage coil.
[0056] When using the high-voltage frame provided by this utility model, firstly, winding needles are inserted into the beginning and end of the frame tube 100; then, the coil is wound along the annular wire groove baffle 200 around the frame tube 100, and the conversion of each level is completed through the opening 201; after the winding is completed, the beginning and end are soldered; next, the low-voltage coil is installed into the frame tube 100, the upper end of the low-voltage coil is assembled with the first positioning block 400 and the second positioning block 401, and the two bottom baffle notches at the lower end of the low-voltage coil are engaged with the positioning plate 402 to lock together, thus completing the assembly of the high and low voltage coils. The iron core is installed in the low-voltage coil, and the entire coil is installed into the outer shell and welded; finally, epoxy resin is poured in through the reserved inlet at the upper end after welding, and after the epoxy resin cures, the COP ignition coil is formed.
[0057] The design of the annular groove baffle 200 effectively prevents cross-contamination between high-voltage and low-voltage coil turns, while improving the uniformity of voltage distribution between high-voltage coil turns. Furthermore, the coordinated use of the first positioning block 400, the second positioning block 401, and the positioning plate 402 ensures the centered positioning of the low-voltage coil. The guide groove 301, acting as an epoxy channel, possesses excellent flowability, enhancing the insulation performance of the high-voltage coil, thereby significantly reducing the defect rate and substantially improving product quality stability.
[0058] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
