Abstract
The utility model relates to an ignition coil, which mainly solves the technical problems that the base of the existing ignition coil is adhered with a shell through resin, so the connection strength of the base and the shell is bad, the cost is high, the appearance is influenced and the like, and is characterized in that a step is arranged in the base, and the end part of the shell is inserted into the base, is attached with the end surface of the step, and is fixed with the base through welding. The utility model has the beneficial effects that a welding mode is adopted to fix the base and the shell together instead of the original direct resin adhering mode, so the connection strength of the base and the shell can be improved, and the working stability of the ignition coil is also ensured; and meanwhile, the assembly is facilitated, the operation is simple, the aesthetic degree of products is improved, and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of auto parts machinery, relates to a kind of spark coil in particular, is mainly used in automotive field.
Background technique
Spark coil is one of critical component of automobile, and it carries out ignition operation by the instruction that receives automobile ECU, and its stability is directly connected to the automobile running performance.Existing spark coil mainly includes iron core, secondary winding, primary air, shell, high-head and iron clad, secondary winding and primary air are nested with successively outside iron core, shell is nested with outside primary air, the iron clad bag is wilful on shell, and high-head is installed in shell one end and is connected with body seal; For ease of the fixed installation of spark coil, be provided with base at the other end of shell, this base by resin bonding on shell; Adopt bonding way, the join strength of base and shell is relatively poor, and the working stability that in use directly influences spark coil is qualitative; Secondly, adopt bonding way technology complicated, cost is higher and not attractive in appearance.
Summary of the invention
Bonding for the base that solves existing spark coil by resin and shell, make the join strength difference and the cost height of base and shell, influence technical problems such as attractive in appearance; The utility model provides a kind of spark coil, and this spark coil can effectively improve the join strength of base and shell, the working stability of guarantee point fire coil, and the simple easy operating of technology, and cost is low.
For solving above technical problem, the technological scheme that the utility model is taked is a kind of spark coil, it includes iron core and reaches secondary winding, primary air, shell and the iron clad that is nested with successively outside iron core, at shell one end high-head is installed, and the other end is equipped with base; It is characterized in that being provided with step in the described base, described outer casing end inserts in the base and the end face of step fits and weld fixing with base.
Further, the step in the described base includes first step and second step, and the end face of described outer casing end and first step fits and fixes by ultrasonic welding and base; It is mutually spacing with shell that described iron clad is nested with on shell the one end, and the other end inserts in the second step of base.
Further, described base is provided with the deck of dead earth diode, and this deck is provided with draw-in groove, and described ground connection diode places in the draw-in groove and fixes with deck.
The beneficial effects of the utility model are base originally to be adopted resin bonding mode shell to link to each other to change welding manner into and shell fixes, and so not only can improve the join strength of base and shell, the working stability of guarantee point fire coil; Simultaneously, also can be convenient to assembling and simple to operate, and can improve the aesthetics of product, reduce production costs; And step is set in base, be convenient to the location of shell and the fastness of base welding like this.
Description of drawings
Fig. 1 is the sectional structure chart of a kind of spark coil of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing the utility model mode of execution is described further:
As shown in Figure 1, the utility model is a kind of spark coil, and it includes iron core 1 and reaches secondary winding 2, primary air 3, shell 4 and the iron clad 5 that is nested with successively outside iron core 1, at shell 4 one ends high-head 6 is installed, and the other end is equipped with base 7; For the base 7 that solves existing spark coil bonding by resin and shell 4, make the join strength difference and the cost height of base 7 and shell 4, influence technical problems such as attractive in appearance, be provided with step 71 in the described base 7, described shell 4 ends are inserted in the base 7 and the end face of step 71 fits and weld fixing with base 7; Adopt resin bonding mode shells 4 to link to each other to change welding manner into shell 4 fixes, so not only can improve the join strength of base 7 and shell 4, the working stability of guarantee point fire coil with base 7 is original; Simultaneously, also can be convenient to assembling and simple to operate, and can improve the aesthetics of product, reduce production costs; And step 71 is set in base 7, be convenient to the location of shell 4 and the fastness of base 7 welding like this.
In the present embodiment, fastness when welding with shell 4 for assurance base 7, step 71 in the described base 7 includes first step 711 and second step 712, and the end face of described shell 4 ends and first step 711 fits and fixes by ultrasonic welding and base 7; It is mutually spacing with shell 4 that described iron clad 5 is nested with on shell 4 the one end, and the other end inserts in the second step 712 of base 7.
In the present embodiment, because the ground connection diode of existing spark coil links to each other with iron clad 5 by the scolding tin mode, the higher relatively and complicated operation of cost like this, working efficiency is lower; Being connected and being convenient to installing and fixing of ground connection diode for ease of ground connection diode and iron clad 5, described base 7 is provided with the deck 72 of dead earth diode, this deck 72 is provided with draw-in groove 721, and described ground connection diode places in the draw-in groove 721 and fixes with deck 72; Increase by a deck 72, like this when assembling ground connection diode, only need the ground connection diode is snapped in the draw-in groove 721 of deck 72, pin with the ground connection diode links to each other with iron clad 5 again, need not so just can be grounded the fixing of diode by scolding tin, effectively reduce production costs, and solid and reliable easy operating.
The foregoing description should not be considered as restriction of the present utility model, but any improvement of doing based on spirit of the present utility model, all should be within protection domain of the present utility model.
