Abstract
The utility model discloses a plug and shell fitting piece for ignition coil, include: the bottom end of the plug is provided with an end panel of which the shell is matched with the drawing die, and the end surfaces of two sides of the end panel are provided with U-shaped grooves to form a parting surface of the plug; the shell is provided with a drawing support shaft matched with the size of the U-shaped groove, when the plug is matched and connected with the shell, the drawing support shaft is inserted in the U-shaped groove in a matching mode, the drawing support shaft and the plug are matched in size and are completely tightly attached to form transition fit, and the drawing junction between the plug and the shell is a sealing surface. The utility model provides a pair of a plug and shell fitting piece for ignition coil can guarantee that the plug is hugged closely completely with the shell cooperation, and the product can not appear leaking the gluey phenomenon after the embedment.
Description
Technical Field
The utility model belongs to the technical field of the ignition coil technique and specifically relates to a plug and shell fitting piece for ignition coil.
Background
Ignition coil is that tens kinds of spare parts are combined, need consider the cooperation and the leakproofness of each part when the combination, and the sealed cooperation of low-voltage head and shell prevents the problem of leaking gluey to exist always, and it is not good to seal to cause the plug to leak gluey, causes the outward appearance bad, so no matter in product design and mould design, all need consider the cooperation and the die sinking direction of plug and shell.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a plug and shell fitting piece for ignition coil.
The technical scheme of the utility model is that: a plug and housing mating piece for an ignition coil, comprising:
the bottom end of the plug is provided with an end panel of which the shell is matched with the drawing die, and the end surfaces of two sides of the end panel are provided with U-shaped grooves to form a parting surface of the plug;
the plug comprises a shell, wherein a drawing support shaft matched with the U-shaped groove in size is reserved on the shell, when the plug is connected with the shell in a matched mode, the drawing support shaft is inserted in the U-shaped groove in a matched mode, the drawing support shaft and the plug are matched in size and are completely tightly attached to form transition fit, and the drawing junction between the plug and the shell is a sealing surface.
Preferably, the corners of the "U" shaped groove are chamfered.
Preferably, the corners of the drawing fulcrum shaft are also cut with chamfers.
Preferably, the unilateral matching of the sealing surface is less than or equal to 5-7 wires.
Compared with the prior art, the utility model discloses following beneficial effect has: the utility model provides a pair of a plug and shell fitting piece for ignition coil has designed the die joint of a new plug, is fitting closely with the shell, avoids leaking the phenomenon appearance that glues.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
Fig. 2 is a cross-sectional view of the overall matching principle of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
As shown in fig. 1 to 2, a plug and housing fitting for an ignition coil includes a plug 1 and a housing 2.
The end panel 101 that this plug 1 bottom was equipped with shell 2 cooperation drawing die, has all seted up "U" groove 102 on the both sides terminal surface of this end panel 101, and the edges and corners cutting in "U" groove 102 has the chamfer, constitutes the die joint of plug 1.
The shell 2 is provided with a drawing support shaft 201 matched with the U-shaped groove 102 in size, the edges and corners of the drawing support shaft 201 are also cut with chamfers, when the plug 1 is connected with the shell 2 in a matched mode, the drawing support shaft 201 is inserted into the U-shaped groove 102 in a matched mode, the drawing support shaft 201 and the casing 2 are matched in size and are completely attached to each other to form transition fit, the drawing junction between the plug 1 and the shell 2 is a sealing surface 3, and the single-side sealing surface is matched with each other to be not more than 5-7 wires.
The utility model discloses a theory of operation does: when the plug parting surface is designed in the mold, the parting surface is divided on the surface of the plug, and simultaneously, when the plug matching surface is subjected to die drawing, the die drawing angle is the same as the die drawing angle of the shell, and the unilateral matching of the sealing surface is also ensured to be within 5-7 filaments;
the plug is ensured to be completely attached to the shell in a matching way, and the glue leakage phenomenon of the product after encapsulation can be avoided.
The above-mentioned embodiments are only preferred embodiments of the present invention, and the scope of the right of the present invention should not be limited thereby, and therefore, modifications, equivalent changes, improvements, etc. made in the claims of the present invention are still included in the scope of the present invention.
