An iron core is arranged inside the top end of the outer shell. One end of the iron core is connected to one end of a permanent magnet. The other end of the permanent magnet is connected to a magnetic conduction component. A primary skeleton is arranged on the outer surface of the iron core.

The structure of this kind of wiring piece cannot meet the wiring requirements of different models of ignition coils and is not universal; 2. When pouring epoxy resin, the wiring piece is prone to displacement, resulting in poor contact between the secondary skeleton and the high-voltage conducting column. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a universal wiring piece and an ignition coil with stable wiring, so as to solve the problems that the existing technology cannot meet the wiring requirements of different models of ignition coils and the wiring piece is prone to displacement.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

Two symmetric second limiting pieces are arranged on the vertical connection line of the wiring holes. The two second limiting pieces and each first limiting piece can cooperate to fix the high-voltage conducting column at the first wiring position or the second wiring position.

[0007] Further, the wiring plate is rectangular, the wiring holes are octagonal, the first limiting pieces are triangular, the second limiting pieces are isosceles trapezoidal, and the horizontal linear distances between the plug plates and the centers of the first wiring position and the second wiring position are 5 mm and 6.5 mm respectively.

[0008] Further, a limiting plate and a bending plate are arranged on the plug plate. The limiting plate is perpendicular to the plug plate, and the bending plate can be bent into a U shape.

[0009] Further, a first bayonet and a second bayonet are respectively provided on the left side and the right side of the wiring board.

[0012] Compared with the prior art, the utility model has the following beneficial technical effects:

[0013] 1. By setting the shape of the wiring hole of the wiring piece of the utility model as an octagon, the effective wiring area of the wiring hole is increased. During the actual assembly of the ignition coil, the high-voltage conductive column can be adjusted between the first wiring position and the second wiring position according to the assembly requirements of different models of ignition coils, which has good versatility; by providing a first limiting piece in the shape of a triangle and a second limiting piece in the shape of an isosceles trapezoid, the contact points of the first limiting piece and the second limiting piece with the high-voltage conductive column are triangular, ensuring the stability of wiring.

[0014] 2. By improving the shape and size of the wiring board of the wiring piece of the utility model, compared with the existing circular wiring board, the stress area of the wiring board is increased, so that the wiring board is not easily deformed during the assembly process, avoiding poor contact between the wiring board and the high-voltage conductive column after the ignition coil is filled with epoxy resin.

[0015] 3. The ignition coil of the utility model can limit the displacement of the wiring piece in multiple directions through the cooperation of the insertion plate and the card slot, the cooperation of the limiting plate and the clamping plate, the cooperation of the first baffle and the first bayonet, and the cooperation of the second baffle and the second bayonet.

[0031] By setting the shape of the connection hole 31 as an octagon, the effective connection area of the connection hole 31 is increased. During the actual assembly process of the ignition coil, the high-voltage conductive column 411 can be adjusted between the first connection position 34 and the second connection position 35 according to the assembly requirements of different models of ignition coils, and the connection requirements of ignition coils with a connection distance of 5-6.5 mm can be met, which has good versatility; by setting the first limiting piece 32 in the shape of a triangle and the second limiting piece 33 in the shape of an isosceles trapezoid, the contact points between the first limiting piece 32 and the second limiting piece 33 and the high-voltage conductive column 411 are triangular, ensuring the stability of the connection; by improving the connection board 3 into a rectangle, the stress area of the connection board 3 is increased, and the connection board 3 is not easily deformed during the assembly process, avoiding poor contact between the connection board 3 and the high-voltage conductive column 411 after the ignition coil is filled with epoxy resin 7.
