Abstract

The utility model discloses an ignition coil, which can prevent the high voltage discharge puncture the shell part near to the high voltage output peg. The utility model comprises a shell and a high voltage wind thread framework inside the shell. A high voltage contact plate is positioned on the high voltage wind thread framework. The feature is that: between high voltage output end of the high voltage contact plate and the shell bottom of the neighborhood of the high output peg, the shell bottom is provided with a stationary dog.

Description

Spark coil

Technical field

The utility model relates to a kind of spark coil, relates in particular to the spark coil that is applicable to automobile.

Background technique

The high-voltage output end that is applied to the spark coil high pressure contact disk of automobile at present is to rely on the positioning device on the high-tension winding skeleton to position.But the high-voltage output end of high pressure contact disk is shifted in installation process easily, in use may cause entire product to lose efficacy owing to electrion is exported near the pin housing partial breakdown with high pressure.

The model utility content

Technical problem to be solved in the utility model provides a kind of spark coil, it can be avoided because the high-voltage output end of high pressure contact disk is shifted in installation process, and in use may be owing to electrion is exported near the pin housing partial breakdown with high pressure.

In order to solve the problems of the technologies described above, the utility model provides a kind of spark coil, the high-tension winding skeleton that it comprises housing and is positioned at housing, on described high-tension winding skeleton, be equipped with the high pressure contact disk, wherein also between near the housing bottom the high-voltage output end of described high pressure contact disk and the high pressure output pin, the bottom of described housing is provided with block.

The height of described block and size can be set according to the rigging position and the size of the high-voltage output end of described high pressure contact disk.

Owing to adopt said structure, the utility model is provided with block between near the housing bottom the high-voltage output end of described high pressure contact disk and the high pressure output pin, therefore can avoid because the high-voltage output end of high pressure contact disk is shifted in installation process, and in use may increase the safety reliability of product owing to electrion is exported near the pin housing partial breakdown with high pressure.

Description of drawings

Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.

Fig. 1 is the structural representation of the utility model spark coil;

Fig. 2 is the decomposition texture schematic representation of the utility model spark coil.

Embodiment

As shown in Figure 1 and Figure 2, it is the structural representation and the decomposition texture schematic representation of the utility model spark coil.Spark coil comprises high-tension winding skeleton 1, housing 2, high pressure contact disk 3, block 4 and high pressure output pin 5, and wherein high-tension winding skeleton 1 is located in the housing 2.One end of high pressure contact disk 3 is assemblied on the high-tension winding skeleton 1, and the other end is the high-voltage output end 31 that links to each other with high pressure output pin 5.

Between near housing 2 bottoms described high-voltage output end 31 and the high pressure output pin 5, housing 2 bottoms are provided with block 4, even high-voltage output end 31 is shifted in installation process like this, in use also can be owing to the existence of block 4, avoid high-voltage output end 31 too near near housing 2 bottoms the high pressure output pin 5, and with housing 2 partial breakdowns.

The position of block 4 is with corresponding with the high-voltage output end 31 of high pressure contact disk 3, and its height and size are set according to the rigging position and the size of high-voltage output end 31.At first, set the size of block 4 then according to the size of high-voltage output end 31 according to the height of the high-voltage safety distance setting block 4 of high-voltage output end 31.

Claims

1, a kind of spark coil, the high-tension winding skeleton that it comprises housing and is positioned at housing, on described high-tension winding skeleton, be equipped with the high pressure contact disk, it is characterized in that: between the high-voltage output end and near the housing bottom the high pressure output pin of described high pressure contact disk, the bottom of described housing is provided with block.

2, spark coil as claimed in claim 1 is characterized in that: the height of described block and size can be set according to the rigging position and the size of the high-voltage output end of described high pressure contact disk.
