Abstract
The utility model discloses a plastic sealing structure of an ignition coil. The ignition coil comprises a casing, a coil and an iron core, wherein the coil is wound on the iron core and then placed in the casing which is provided with an opening. The plastic sealing structure is characterized in that a support is arranged at the position of the opening of the casing, and epoxy resin is poured at the position of the support to enable the casing to be in a completely-sealed state. The plastic sealing structure can effectively improve plastic sealing strength at the position of the opening of the casing, enables a plastic seal at the position of the opening to not easy to crack, and prolongs service life of the ignition coil accordingly.
Description
Technical field
The utility model relates to the ignition coil that uses on a kind of motor vehicle, and particularly the envelope of ignition coil is moulded structure.
Background technology
Ignition coil on the motor vehicle is a kind of transformer that can produce the required high pressure of igniting, all comprises housing, winding, iron core basically, winding on the iron core after; Be sealed in the housing; An opening is set on the housing, be wound with the iron core of winding in installation after, need this opening is sealed.What often adopt at present is directly poured with epoxy resin to be sealed it at opening part.Because the epoxy resin that cast is a large amount of, its intensity is not high, and in use easy of crack causes ignition coil to scrap, the useful life of the ignition coil of shortening.
Summary of the invention
In view of the deficiency that background technology exists, the technical problem that the utility model will solve provides a kind of envelope with ignition coil of sufficient intensity and moulds structure.
For this reason; The utility model adopts following scheme to realize: a kind of envelope of ignition coil is moulded structure, and its ignition coil comprises housing, winding and iron core, and wherein winding is placed in the said housing on iron core; Said housing has opening part; The opening part that it is characterized in that said housing is provided with support, and waters with epoxy resin at the support place, makes housing be in full closeding state.
Said support is netted.
In the utility model, before the casting epoxy resin, at the shell nozzle place support is set earlier, casting epoxy resin seals and moulds housing airtightly again, makes the envelope at shell nozzle place mould intensity and is improved, and is not easy to crack, thereby prolonged the useful life of ignition coil.
Description of drawings
Combine accompanying drawing to further describe the relevant details of the utility model below again.
Fig. 1 is the utility model structure chart;
Fig. 2 is the utility model rack assumption diagram;
Fig. 3 seals the structure chart after moulding for the utility model.
Embodiment
With reference to accompanying drawing; The envelope of this ignition coil is moulded structure, and its ignition coil comprises housing 2, winding 1 and iron core 3, and wherein winding 1 is placed in the said housing 2 on iron core 3; Said housing 2 has opening part; The opening part of said housing 2 is provided with support 4, and waters with epoxy resin at support 4 places, makes shell 2 bodies be in full closeding state.Before casting epoxy resin, support 4 is set, during earlier just as building; Before the cast concrete, arrange that earlier reinforcing bar is the same, concrete intensity is greatly enhanced; The utility model too, its intensity of the epoxy resin of cast also is greatly improved, thereby in long-term use; It is not easy to crack to seal the epoxy resin of moulding the place, makes housing 2 airtight for a long time, to improve the useful life of ignition coil.Said support 4 is netted, and this network 4 can have mean allocation as skeleton when casting epoxy resin, and the effect of moulding on the intensity in the raising envelope is optimal.
Claims (2)
1. the envelope of an ignition coil is moulded structure; Its ignition coil comprises housing, winding and iron core; Wherein winding is placed in the said housing on iron core, and said housing has opening part, it is characterized in that the opening part of said housing is provided with support; And water with epoxy resin at the support place, make housing be in full closeding state.
2. require the envelope of 1 described ignition coil to mould structure according to claim, it is characterized in that said support is netted.
