Detailed Implementation

[0024] The terms “first,” “second,” “third,” etc., are used only for distinguishing descriptions and do not indicate a sequence number, nor should they be interpreted as indicating or implying relative importance.

[0025] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0026] In the description of this application, it should be noted that the terms "inner", "outer", "left", "right", "upper", "lower", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0027] In the description of this application, unless otherwise expressly specified and limited, the terms “set up,” “install,” “connect,” and “link” shall be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral connection; as a mechanical connection or an electrical connection; as a direct connection or an indirect connection through an intermediate medium; or as a connection within two components.

[0028] The technical solution of this application will now be clearly and completely described with reference to the accompanying drawings.

[0029] Reference Figures 1-5 This utility model provides a high-voltage groove-wound pen-type ignition coil, including a housing 100, one end of which is provided with a high-voltage electrode assembly 200, and the other end is provided with an ignition module 800.

[0030] An iron core 600 is provided inside the outer casing 100, and a slotted high-voltage coil assembly 500, a low-voltage coil assembly 400 and a sleeve 300 are sequentially sleeved outside the iron core 600.

[0031] One end of the outer casing 100 is provided with a first positioning groove 101 and a second positioning groove 102. The low-voltage coil assembly 400 is provided with a first positioning protrusion 402 that matches the first positioning groove 101 and a second positioning protrusion 401 that matches the second positioning groove 102, and the first positioning groove 101 and the second positioning groove 102 are of different sizes.

[0032] In some embodiments, the high-voltage slotted pen-type ignition coil core 600 is sequentially fitted with a slotted high-voltage coil assembly 500, a low-voltage coil assembly 400, a sleeve 300, and a housing 100; wherein, one end of the housing 100 is provided with a high-voltage electrode assembly 200, and the other end is provided with an ignition module 800.

[0033] During assembly, the low-voltage coil assembly 400 is first assembled inside the housing 100, and then the slotted high-voltage coil and the iron core 600 are assembled together and then assembled inside the low-voltage coil assembly 400. An iron core cap 700 connected to the slotted high-voltage coil is provided on the iron core 600, so that the iron core 600 can move effectively inside the slotted high-voltage coil.

[0034] To improve the accuracy of the assembly of the low-voltage coil assembly 400 with the housing 100, a first positioning groove 101 and a second positioning groove 102 are provided at one end of the housing 100. The first positioning groove 101 and the second positioning groove 102 are of different sizes. This effectively avoids the first positioning protrusion 402 being incorrectly installed on the second positioning groove 102 and the second positioning protrusion 401 being incorrectly installed on the first positioning groove 101 during the assembly of the low-voltage coil assembly 400. The first positioning protrusion 402 cooperates with the first positioning groove 101, and the second positioning protrusion 401 cooperates with the second positioning groove 102, so that the low-voltage coil assembly 400 is accurately assembled in the housing 100, and the assembly is simple.

[0035] Reference Figure 1 In an optional embodiment, the high-voltage electrode assembly 200 is snapped into the slotted high-voltage coil assembly 500, and the other end of the slotted high-voltage coil assembly 500 is welded to the ignition module 800.

[0036] The high-voltage electrode assembly 200 is snapped into the slotted high-voltage coil assembly 500, and the other end of the slotted high-voltage coil assembly 500 is welded to the ignition module 800; the slotted high-voltage coil assembly 500 and the ignition module 800 are connected by welding, and the slotted high-voltage coil is not directly connected to the ignition module 800.

[0037] Reference Figure 3In an optional embodiment, one end of the low-voltage coil assembly 400 is provided with a third positioning groove 403 and a fourth positioning groove 404, and the slot-wound high-voltage coil assembly 500 is provided with a third positioning protrusion 501 that matches the third positioning groove 403 and a fourth positioning protrusion 502 that matches the fourth positioning groove 404, and the third positioning groove 403 and the fourth positioning groove 404 are of different sizes.

[0038] To ensure precise assembly of the low-voltage coil assembly 400 and the slot-wound high-voltage coil assembly 500, a third positioning groove 403 and a fourth positioning groove 404 are provided at one end of the low-voltage coil assembly 400, and the third positioning groove 403 and the fourth positioning groove 404 are of different sizes; this ensures that the third positioning protrusion 501 is precisely assembled in the third positioning groove 403 and the fourth positioning protrusion 502 is precisely assembled in the fourth positioning groove 404.

[0039] In an optional embodiment, one end of the low-voltage coil assembly 400 is welded to the ignition module 800.

[0040] Both the low-voltage coil assembly 400 and the slotted high-voltage coil assembly 500 include a frame. Both the low-voltage coil assembly 400 and the slotted high-voltage coil assembly 500 are welded to the ignition module 800, but the low-voltage coil assembly 400 and the slotted high-voltage coil assembly 500 are not directly connected.

[0041] Reference Figure 1 and Figure 5 In an optional embodiment, a low-voltage socket 900 is also included, which is mounted on the end of the housing 100 away from the high-voltage electrode, and the ignition module 800 is welded to the low-voltage socket 900.

[0043] The low-voltage socket 900 is provided with a socket positioning protrusion 103 and a socket positioning groove 901 that matches it.

[0044] In an optional embodiment, a filling layer is provided on the housing 100, the filling layer being used to fix the low-voltage socket 900, the ignition module 800 and the housing 100.

[0045] In an optional embodiment, the filler layer is made of epoxy resin.

[0046] When epoxy resin is injected into the housing 100, the epoxy resin flows downward from the gap between the low-voltage coil assembly 400 and the slotted high-voltage coil assembly 500, and physically isolates the low-voltage coil assembly 400 and the high-voltage coil assembly; and forms a filling layer on the housing 100, which firmly fixes the low-voltage socket 900, the ignition module 800 and the housing 100 together.

[0047] In an optional embodiment, a core cap 700 is provided at the end of the core 600 that is away from the high-voltage electrode assembly 200.

[0048] The high-voltage slotted pen-type ignition coil provided by this utility model has a high-voltage electrode assembly 200 at one end of its outer shell 100 and an ignition module 800 at the other end. A slotted high-voltage coil assembly 500, a low-voltage coil assembly 400, and a sleeve 300 are sequentially sleeved outside the iron core 600. A first positioning groove 101 and a second positioning groove 102 are provided on the outer shell 100, which match the first positioning protrusion 402 and the second positioning protrusion 401 on the low-voltage coil assembly 400. This allows the low-voltage coil assembly 400 to be precisely assembled inside the outer shell 100. This improves the convenience and reliability of assembling the high-voltage slotted pen-type ignition coil, and the high-voltage slotted pen-type ignition coil has a compact structure.
