[0017] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution in the embodiment of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiment is a part of the embodiment of the present application, not all of the embodiments. The fact that all the technical features in the dependent claims are listed in an embodiment does not mean that the part is a necessary technical feature. This embodiment is for the purpose of simply and clearly describing the technical solution.

[0018] Example 1, reference Figures 1 to 4As shown, an electronic pulse igniter includes a housing 1, a pin terminal 11 is provided at one end of the housing 1 and an opening 12 is provided at the other end, a receiving cavity 13 is provided in the housing 1, a circuit board 2 is provided in the receiving cavity 13, a coil 21 and a capacitor 22 are provided on the circuit board 2, and a glue potting is poured into the housing 1, and the coil 21 is insulated only by the glue potting. The single glue potting insulation optimization production process is adopted, and the process steps are reduced compared with the traditional coil 21 that is insulated by encapsulation.

[0019] In this embodiment, a partition 14 is integrally provided in the middle of the accommodating cavity 13, and the capacitor 22 and the coil 21 are arranged in parallel. The partition 14 is inserted in the gap between the capacitor 22 and the coil 21. The partition 14 cooperates with the electronic components to realize the positioning of the circuit board 2. The structure is simple, the assembly structure is optimized, and the assembly is more convenient. A positioning piece 15 for mounting the circuit board 2 is also provided on the inner edge of the shell. The partition 14 and the positioning piece 15 on one side of the coil 21 are sandwiched between the coil 21, and the coil 21 can be accurately assembled when positioning and assembling, so as to realize the effect of easy loading and limiting the position upon entry. The structure of the partition 14 and the positioning piece 15 optimizes the fixing scheme and makes assembly more convenient.

[0020] In order to fix the pulse igniter in this embodiment, fixing ears 16 are extended on both sides of the housing, and a grounding plate is attached to one of the fixing ears 16. The grounding plate extends into the housing and is electrically connected to the ground wire of the circuit board 2. The grounding plate is arranged at the fixing ear 16 to facilitate the grounding connection between the screw and the housing 1.

[0021] In order to increase the creepage distance of the internal electricity of the igniter, this embodiment also includes a cover 3 arranged at the opening 12. The cover 3 is used to cover and isolate the contact between the glue filling and the shell, thereby increasing the creepage distance. Since the contact area between the fixed surface and the surface is large, it is necessary to further increase the creepage distance. The opening 12 is provided with a shoulder 17 for embedding the cover 3, and the shoulder 17 is provided with a buckle protrusion 18 for buckling the cover 3.
