The outer configuration of a casing is provided with four mounting seats; two mounting seats are embedded with the sleeves of mounting holes in advance, and the upper part of the two mounting seats are provided with the elongated bar-shaped connecting pieces which are contacted with the U-shaped magnetic conductors of the two cavities which are horizontally arranged. The central position of the cavity is provided with an iron core in the shape of-, and the outer part of the cavity is provided with a primary coil which is connected with the terminal of a connector socket. Twoo fixing holes arranged on the frame of the secondary coil are fixedly connected with high-pressure nozzles, and the bobbin winding head of the secondary coil is connected with the conductive head of the high-pressure nozzle. Thee convex thin wall ring of the casing is circled inside of the closed configuration and then is provided with embedding materials. The utility model has small volume, light weight, easy use, and dependable performance.
Description
Affiliated technical field
The utility model relates to a kind of spark coil, and being particularly useful for four novel cylinders does not have distributor electronic fuel injection engine ignition system.
Background technique
At present, various four cylinders do not have in the distributor EFI ignition mechanism, coil winding and column distribution not with the spark coil of ignition controler, its high pressure mouth generally adopts integrated structure design, to guarantee its accurate centre distance, for this reason, make high pressure nozzle assembly complex structure, when single high pressure mouth can not use because of defective, can cause four high pressure mouthes of whole one all can not use; In addition because four high pressure mouth one, its centre distance fix and distance little, be that two groups of coils and four high pressure mouthes are assembled simultaneously and brought difficulty; Four high pressure mouth one, its stiffening rib that is used to connect each high pressure mouth takies certain space, and two groups of unit need good isolation, need certain space, thus the overall volume of coil is increased, increased the weight of product and unnecessary material simultaneously and filled.
Summary of the invention
In order to overcome above-mentioned deficiency, it is a kind of reasonable in design that the utility model provides, and four cylinders of compact structure do not have distributor electronic fuel injection engine usefulness, the spark coil of two unit windings and column distribution.
For achieving the above object, the technical solution adopted in the utility model is: on the exterior contour of shell, be distributed with four fitting seats, be embedded with the mounting hole sleeve in two fitting seats, there is the prolongation Jumper upper end portion, prolonging Jumper contacts with the horizontal positioned U type magnet case of two cavitys respectively, there is the in-line iron core in the center portion of cavity, its outside is provided with primary air, the elementary line of primary air is connected with the terminal of connector socket, two fixed holes and high pressure mouth on the skeleton of secondary winding are connected and fixed, and the bobbin winding head of secondary winding is connected with conductive head in the high pressure mouth, and the convex thin-walled of shell is around being provided with Embedding Material in the closed outline.
Advantage of the present utility model is: volume is little, and is in light weight, easy to use, reliable performance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is the shell schematic representation.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
By Fig. 1~Fig. 3 as seen, on the exterior contour of the shell 8 of described spark coil, be distributed with four fitting seats, be embedded with mounting hole sleeve 7 in two fitting seats, there is the prolongation Jumper upper end portion, prolonging Jumper contacts with the U type magnet case 6 of two cavitys respectively, magnet case 6 is a U profile horizontal positioned, keep Spielpassung with 15 of cavity center portion, about 0.05mm~the 2mm of its gap 12 distances, in the outside of in-line iron core primary air 4 is arranged, the elementary line of primary air 4 is connected with the terminal of connector socket 1, in the outside of primary air 4 are secondary winding 3, and the skeleton of secondary winding 3 has two high pressure mouth fixed hole is installed, and is connected with high pressure mouth 2, nut 9 is connected with the high pressure conductive head, the bobbin winding head of secondary winding 3 is connected with conductive head in the high pressure mouth 2, and the internal structure and the Placement of two cavitys are identical, and the convex thin-walled of shell 9 is around being provided with Embedding Material in the closed outline.
Described shell 9, there are four ear shape fitting seats the outside and give the outer projection that is embedded with U type magnet case 6, wherein in two fitting seats mounting hole sleeve 12 is arranged, in two fitting seats mounting hole sleeve 7 is arranged in addition, the prolongation Jumper of mounting hole sleeve 7 upper end portions and U type magnet case 6 join, and end platform positioning groove 14 is arranged in it, and magnet case 6 is arranged in the cavity, port recess 15, two chambeies of shell 9 are by the isolation bar 12 of band dual-cavity.
The utility model spark coil, use is in the internal-combustion engines vehicle ignition system, ignition controler wherein is connected with connector socket 9, by microcomputer control optimum igniting trigger signal in period is inputed to ignition controler, ignition controler is in chronological order respectively with the failure of current or the conducting of two primary air 4.When the primary current of a primary air 4 is cut off, primary air in its place cavity 16 or 17 generates an electromagnetic field, most of magnetic line of force constitutes closed magnetic circuit by yi word pattern iron core 5 and E type magnet case 6, the variation in magnetic field makes primary air 4 and 3 of secondary winding produce electromagnetic coupling, in secondary winding 3, produce high induced electromotive force, its secondary lighting outlet is connected with high pressure conductive head 7, make two spark plug discharges that link to each other with high pressure conductive head 7, light the mixed gas in the cylinder of with it corresponding compression stroke, promote the piston acting.
