Description

Technical Field

[0001] This utility model relates to the field of ignition coils, and more specifically, to the core structure for ignition coils. Background Technology

[0002] An ignition coil is an actuator that ignites the air-fuel mixture in an engine cylinder by providing ignition energy, and the iron core is the core component of the ignition coil.

[0003] The existing iron core is composed of multiple layers stacked together and then joined by riveting. The joint is not strong, the assembly is not convenient, and it also requires rivets and other components, making it inconvenient to use. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide an iron core structure for ignition coils. After the iron chips are stacked, positioning blocks are snapped into the inner ends on both sides for positioning. After the coil is wound, the positioning blocks are locked, which can position each other with the iron core, making the connection firm and convenient to use.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] The core structure for the ignition coil includes iron chips stacked together. A first positioning block is engaged with the inner surface of one side of the core for positioning, and a second positioning block is engaged with the inner surface of the other side of the iron chips for positioning. A coil is wound around the surface of the iron chips. After the iron chips are stacked, the positioning blocks are engaged with the inner ends on both sides for positioning. After the coil is wound, the positioning blocks are locked, which can position each other with the core, making the connection firm and convenient to use.

[0007] Furthermore, the upper and lower surfaces of the iron core are provided with grooves, and the coil is wound on the inner surface of the groove, which facilitates coil positioning and winding, and ensures stable winding.

[0008] Furthermore, the first and second positioning blocks adopt a corner block structure, which facilitates their insertion into the iron core surface.

[0009] Furthermore, the outer end surfaces of the first and second positioning blocks are provided with positioning grooves, which are engaged with the inner surface of the iron chip for easy engagement and positioning.

[0010] Furthermore, one side of the coil is wound and pressed against the inner surface of the first positioning block, and the other side is wound and pressed against the inner surface of the second positioning block. This facilitates the outward pressing of the two positioning blocks after the coil is wound, which can lock the iron chip together and make it easy to fix.

[0011] Furthermore, the inner surfaces of the positioning grooves of the first and second positioning blocks are provided with inclined cuts. When the positioning blocks are pressed outward, the iron chip can be pressed inward to shrink and tighten with each other, which is convenient for fixing.

[0012] Furthermore, the first and second positioning blocks are made of plastic, which facilitates processing.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] (1) After the iron chips are stacked, the positioning blocks are snapped into the inner ends on both sides for positioning. After the coil is wound, the positioning blocks are locked and can be positioned with the iron core. The combination is firm and convenient to use.

[0015] (2) The upper and lower surfaces of the iron core are provided with grooves, and the coil is wound on the inner surface of the groove, which facilitates coil positioning and winding, and ensures stable winding.

[0016] (3) The first positioning block and the second positioning block adopt the corner block structure, which is easy to be inserted into the iron core surface. The outer end surfaces of the first positioning block and the second positioning block are provided with positioning grooves. The positioning grooves are engaged with the inner surface of the iron chip, which is easy to engage and position. One side of the coil is wrapped and pressed into the inner surface of the first positioning block, and the other side is wrapped and pressed into the inner surface of the second positioning block. This makes it easy to press the two positioning blocks outward after the coil is wound, so that the iron chip can be locked together and fixed. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figure 1-6 The core structure for the ignition coil includes an iron chip 1, which is stacked together. A first positioning block 2 is engaged with the inner surface of one side of the iron core 1 for positioning, and a second positioning block 20 is engaged with the inner surface of the other side of the iron chip 1 for positioning. A coil 3 is wound around the surface of the iron chip 1. Grooves 100 are provided on the upper and lower surfaces of the iron core 1. The coil 3 is wound around the inner surface of the groove 100, which facilitates positioning and winding and ensures stable winding.

[0027] The first positioning block 2 and the second positioning block 20 adopt a corner block structure. After the iron chip 1 is stacked together, it is inserted into the positioning block. The outer end surfaces of the first positioning block 2 and the second positioning block 20 are provided with positioning grooves 220. After being inserted, the positioning grooves 220 are engaged with the inner surface of the iron chip 1, which facilitates the positioning of the iron chip 1. The coil 3 is wound. One side of the coil 3 is wound and pressed on the inner surface of the first positioning block 2, and the other side is wound and pressed on the inner surface of the second positioning block 20.

[0028] The two positioning blocks are pressed outward after the coil 3 is wound, and they can lock the iron chip 1 together for easy fixation.
