Description
Technical field
The utility model relates to a kind of ignition coil, particularly relates to the insulation system in ignition coil.
Background technology
Along with automotive gasoline engine is to the future development of high rotating speed, high compression ratio, high-power, low oil consumption and low emission, traditional igniter is not suitable with instructions for use.The core component of igniter is ignition coil and switching device, improves the energy of ignition coil, and spark plug just can produce the spark of enough energy, and this is the primary condition that igniter adapts to Modern Engine operation.Two groups of coils, primary coil and secondary coils are had inside common ignition coil.The thicker enamelled wire of primary coil, uses the enamelled wire of 0.5-1 millimeter usually around about 200-500 circle; The thinner enamelled wire of secondary coil, the usual enamelled wire by 0.1 millimeter is around about 15000-25000 circle.Primary coil one end connects with low-tension supply (+) on car, and the other end connects with switching device (circuit breaker).Secondary coil one end connects with primary coil, and the other end connects with high-voltage line output and exports high-tension electricity.And primary coil and secondary coil all need to utilize elementary skeleton and secondary framework to fix.When engine igniting coil works, secondary coil two ignition voltage output alternately produces the ignition voltage of about 30kV, so secondary coil and primary coil U electrical potential difference maximum point are positioned at secondary coil two ignition voltage output be about 30kV.Therefore potting resin insulating barrier between elementary skeleton and secondary framework.
Be disclosed in present patent document: " a kind of engine igniting coil (CN101943099A) ", comprise armature winding, secondary winding, secondary winding on secondary framework, is wound around enamelled wire as secondary coil, the two ends of the enamelled wire that secondary framework is wound around are drawn as secondary coil ignition voltage output from the two ends of secondary framework, armature winding is wound around enamelled wire as primary coil on elementary skeleton, the cavity that the secondary framework inwall that primary coil is placed in secondary winding is formed is interior and primary coil leaves insulation distance with between secondary inboard wall of skeleton, primary coil mid portion is less than the insulation distance of primary coil two end portions to secondary framework inwall to the insulation distance of secondary framework inwall.But still there is breakdown risk at high pressure needle foot.
Summary of the invention
It is simple that the utility model provides a kind of structure, can effectively prevent high-voltage breakdown components and parts, safe and reliable ignition coil; The high pressure solved in the ignition coil existed in prior art easily punctures components and parts, the technical problem that insulation effect is bad.
Above-mentioned technical problem of the present utility model is solved by following technical proposals: a kind of ignition coil, comprise elementary skeleton and be positioned at the secondary framework outside elementary skeleton, the outer solderless wrapped connection of elementary skeleton has primary coil, on secondary framework, solderless wrapped connection has secondary coil, insulation distance is left between elementary skeleton and secondary framework, in insulation distance, embedding has insulating resin, the draw-in groove connecting high pressure needle foot is provided with in one end of secondary framework, at installation high-voltage stitch, place is provided with interlayer insulating layer, described interlayer insulating layer is positioned at the side near elementary skeleton, interlayer insulating layer comprises three layers, be followed successively by overlying plastic layer, insulating resin packed layer and lower floor's plastic layer.There is voltage difference between primary coil and secondary coil, traditional insulation is exactly at both support embedding insulating resins.But stitch is as high-pressure side, the skeleton of its installed position is subject to the impact of its installing space, easily to puncture, therefore this programme is provided with three-layer insulated overcoat herein, add the effect of insulation, improve barrier propterty, ensure that power supply also can not puncture components and parts when more than 30kv, improve the safe application performance of product.Also have one deck to be insulating resin packed layer in three layers, electrical insulation capability and Heat stability is good, anti-breakdown ability is strong.
As preferably, the described layer of two layers of plastic is up and down one-body molded, and between two layers of plastic layer, offer fill gaps has insulating resin.Upper and lower two-layer one-body molded, structure is simple, embedding insulating resin of slotting between the plastics of both sides, and the insulating resin embedding between primary coil and secondary coil can be carried out simultaneously, and technique is simple, and insulation property are more excellent.
As preferably, the Thickness Ratio of described overlying plastic layer, insulating resin packed layer and lower floor's plastic layer is 1:1:1 ~ 1:2:3.Improve insulation property.
As preferably, the draw-in groove of described fixing high pressure needle foot connects with overlying plastic layer.
Therefore, ignition coil of the present utility model possesses following advantage: (1) arranges three-layer insulated interlayer, improves insulation effect, prevents high-voltage breakdown components and parts, product is used safer; (2) the wherein one deck in insulating barrier is resin filling, further reinforced insulation effect; (3) resin filling layer is direct embedding of slotting between two layers of plastic layer, and technique is simple, easy to operate.
