Abstract
The utility model relates to an ignition coil group (1) for an internal-combustion engine, wherein, layered magnetic cores (3, 4) can be embedded into a casing (2) by using moulded plastic filling. The first magnetic core (3) is composed of an H magnetic core and made of a standard iron sheet with no orientation, and the second magnetic core (4) is an I magnetic core and is made of an oriented iron sheet with a granular structure; the second magnetic core (4) can form a closed magnetic circuit through the first magnetic core (3). Under the condition of the same power of the ignition coil group, the structural height of the second magnetic core (4) is smaller than that of the existing magnetic core; therefore, the structural height of the ignition coil group is smaller than that of the existing ignition coil group. The utility model is used for cars.
Description
The utility model relates to a kind of ignition coil for internal combustion engine group.
Such ignition coil is known, as the disclosed ignition coil of DE3741003C2.The every bit live wire of these known ignition coils has a primary coil and a level coil as winding, and secondary coil and primary coil electric insulation have two high-voltage output ends that are connected with the energy meter plug respectively in the double spark ignition coil.
Can simplify installation by the many ignition coils of assembling in housing and connect each ignition coil, and the function of ignition coil is irrelevant mutually.
High-voltage output end also claims secondary link to place outside the winding.The volume size of winding is proportional, because they are very big around structure height that the relative magnetic core of living has.The proportional housing that protrudes in of secondary thus link, the result causes the structural volume of ignition coil group bigger.
The purpose of this utility model is to provide a kind of to be made its compactness and ignition coil group that plant oneself few by reducing structure height.
Ignition coil group of the present utility model has the electric insulation housing, embed first magnetic core that at least one second magnetic core forms closed magnetic path that passes through in the electric insulation housing, wherein each permeability magnetic material by the layering setting of first and second magnetic cores constitutes the core group, primary coil and secondary coil are set on second magnetic core, and first magnetic core is made of standard matter unshakable in one's determination and second magnetic core is made of the iron core of grain structure orientation.
Preferably, the connector of ignition coil group of the present utility model provides at least one low pressure link and at least one high pressure link to be embedded in the electric insulation housing.
Preferably, first magnetic core of ignition coil group of the present utility model is half H shape and second magnetic core is an I shape at least.
Ignition coil group of the present utility model is in light weight, and the space that occupies is little, is easy to arrange.
Further described embodiment of the present utility model with the following description in the accompanying drawing, wherein,
Fig. 1 shows the end view of partial firing coil groups;
Fig. 2 shows the vertical view of ignition coil group.
In housing 2, load the filler (not shown) of making by moulded plastic, be used to make primary coil 6 and secondary coil 9 mutual electric insulations and make its location.
First magnetic core 3 of the present utility model is the magnetic cores with standard matter unshakable in one's determination, and the 2nd magnetic core 4 has the matter unshakable in one's determination of grain structure orientation, and its structural volume reduces according to the increase of the magnetic conductivity of giving fixed-field, and therefore, second magnetic core 4 is littler than known structure.
The ignition coil group is 1 little, weight is less, because the structure space that occupies is little, is easy to arrange.
The space that magnetic core 4 is saved makes all connectors such as low pressure link 8 be contained in the housing with high pressure link 12 collection with cover 14 and embeds moulded plastic.
In addition as can be seen from Figure 2, magnetic core 3 has also constituted half of so-called C magnetic core that magnetic core 4 only is set.
Claims (3)
1, ignition coil for internal combustion engine group (1), has electric insulation housing (2), embed first magnetic core (3) that at least one second magnetic core (4) forms closed magnetic path that passes through in the electric insulation housing (2), wherein magnetic core (3,4) each permeability magnetic material by the layering setting constitutes core group (5), primary coil (6) and secondary coil (9) are set on second magnetic core (4), it is characterized in that, first magnetic core (3) is made of standard matter unshakable in one's determination and second magnetic core (4) is made of the matter unshakable in one's determination of grain structure orientation.
2, ignition coil group as claimed in claim 1 is characterized in that, the connector (8,12) of all ignition coil groups (1) is embedded in the housing (2) by at least one low pressure link (8) and at least one high pressure link (12).
As the ignition coil group of claim 1 or 2, it is characterized in that 3, first magnetic core (3) is half H shape and second magnetic core (4) is an I shape at least.
