The present invention relates to a pack-type automotive ignition coil assembly using a pencil-type primary and secondary coil windings, and more particularly, in the construction of the automotive ignition coil, the operation reliability is high and compact. To the provision of a possible ignition coil.

Automotive ignition coil is a component to deliver high voltage to the spark plug (IP) mounted on the cylinder to provide the heat source required for the initial combustion of the mixer, and to ignite the high voltage generated by the ignition coil through an ignition distributor or an ignition cable. It is divided into a distributor type to be transmitted to the plug (IP) and direct ignition type directly connected to the spark plug (IP) mounted to each cylinder.

The distributor type applies the high voltage generated from the ignition coil to the ignition distributor through the cable, and the ignition distributor receiving the high voltage is connected to the ignition plug (IP) through the cable to distribute the high voltage required for combustion. By having a high risk of loss of high voltage generated in the ignition coil, there is a problem that causes unnecessary components and the resulting cost increase.

The direct ignition type is configured to apply high voltage by connecting only the ignition cable between the ignition coil and the spark plug (IP) phase, eliminating the ignition distributor, minimizing the loss of voltage and reducing related parts, thereby reducing the performance, quality and cost. Although a significant contribution to the reduction, the ignition cable is exposed to the engine heat, and the cable interposed between each cylinder and the cable occurs, there is a problem that there is a concern that the high voltage is lost.

In view of the above-mentioned problems, recently, in order to solve the problems of the distributor type and the direct ignition type, an ignition coil using a pencil-type coil that is connected to the ignition plug (IP) directly to apply a high voltage has been widely used. have.

In the configuration of a sailor or a sailor of the present applicant, which has been conventionally proposed, a configuration capable of directly igniting by constructing an independent single pencil-type ignition coil has been proposed.

It is not easy to install a single pencil-type ignition coil on each ignition side terminal, it requires a large number of auxiliary parts, and it is difficult to secure a mounting space. Had

The present application is characterized by providing a pack-type ignition coil assembly having a configuration most suitable for configuring such a pencil-type ignition coil into a single pack.

By providing the above-described configuration, the present invention enables compact mounting in the mounting space, reduction of manufacturing cost, and improvement of operation reliability.

The present invention to solve the above problems,

In constructing an automotive ignition coil by combining a plurality of pencil-type coils; The ignition coil is,

It basically provides a configuration including a shield plate which is a bent body of a metal plate material which is bent along the outer contour of the coil pack housing and is in close contact,

Furthermore, various modified embodiments are further disclosed.

Hereinafter, the configuration and operation of the present invention will be described with reference to the accompanying drawings.

Front view, side view, and only FIGS. 8 a, b, and c are side views, front views, and partially enlarged views showing the windings of the secondary coil, excluding the extended protrusions.

The pack-type automotive ignition coil assembly using the pencil-type coil of the present invention is configured by storing a plurality of pencil-type coils in an optimal housing, and supplying ignition power to the ignition plugs IP of the plurality of engines. Providing a configuration is a basic technical idea.

Although the present invention discloses a configuration in which the spark plug IP to the four cylinders can be directly ignited by way of example, it is possible to expand as a configuration capable of direct ignition further as needed. The idea of phosphorus is explained in more detail.

1 to 2 are perspective views of a completed exemplary appearance of a pack type automotive ignition coil assembly (IC) using the pencil coil of the present invention.

Coil pack housing 1, which is injection molded into a single housing as a molding material selected from one or more of various injection molding materials having excellent electrical insulation,

The pair of coil receiving pipes 2, 3, which are disposed to face each other, are integrally molded to be disposed in the shape of a part of a cut body of the tubular body.

The coil receiving tubes 2 and 3 are arranged in parallel and are connected by connecting bridge portions 40 as plate-shaped bridges of various shapes therebetween. As will be described later, the connecting bridge portion 40 is insert-molded with a pair of metal bushings 41, and can be mounted with a bolt or the like on an engine block portion (not shown).

In the related art, the bushing 41 for the mounting includes a separate lug-shaped fixture or a fixing lug portion protruding outward, thereby increasing mounting space and causing interference between adjacent components.

However, by having the configuration inserted into the connecting bridge portion 40 in the center portion, the mounting space has a useful compactness.

One side of both ends of the coil receiving tube (2, 3) is integrally formed as a receiver forming the closed closed end (2 ', 3') and the other side to open open end (2 ", 3") do.

It will be described in more detail together with some circuits to the engine electric field of the ignition device of FIG.

On the upper side of the coil pack housing 1, a terminal body 15 for routing wiring, which is an output wiring O1, O2, O3, O4 to each spark plug IP, is shown in FIG.

It is a tubular body in which terminal towers 11, 12, 13, and 14, which are built, by means of threaded fastening 15 'and spring fitting using a spring coupling, are erected and molded to accommodate the member inward.

The reason why the terminal towers 11, 12, 13 and 14 are formed in such a tower shape is that the terminal towers 11, 12, 13 and 14, which are output terminals on the high voltage side, are preferably distances from the ground formed in the engine block or the like. It is configured to prevent leakage of high voltage when routing secondary cable as far as possible.

Therefore, as the configuration of the terminal tower (11, 12, 13, 14) is to maximize the distance between the ground and the terminal connection work for routing can also be easily made from the upper side.

Further, the connector as an interface for connection to the primary wiring I of the engine control module M to the open ends 2 ", 3" side of the coil receiving tube 2, 3 of the coil pack housing 1. 20 is inserted and fixed to the center portion to be detachable.

The connector 20 is inserted in the insertion groove 21 and the connector formed in the coil pack housing 1 so that the connector 20 can be inserted or removed in a direction parallel to the axial direction of the entire coil pack housing 1. On the outskirts of 20,

After forming the fitting protrusion 22 inserted into the insertion groove 21 integrally formed by pressing and fixing the connector 20 into the insertion groove 21 of the coil pack housing 1, epoxy resin potting ( EP) or the like.

As shown in FIG. 1,

Epoxy resin potting (EP), which is carried out to insert the pencil coil 50 and close the open ends 2 " and 3 " 20), the reduction of epoxy resin potting (EP) and the thermal stability due to the epoxy resin potting (EP) can be achieved.

The insertion groove 21 is a channel shape having a roughly "c" shape in cross section, which is suitable for pressing the fitting protrusion 22 by pressing, and the channel shape may be configured in the connector 20.

In addition, from the standpoint of certain designs, the connectors 20 formed at the open ends 2 ", 3" of the coil receiving tubes 2, 3 of the coil pack housing 1 interfere with the assembly of the pencil coil 50. Since the connector 20 and the coil pack housing 1 may be integrally formed, the connector 20 and the coil pack housing 1 may be configured.

Into the coil receiving tubes 2 and 3 described above, pencil-type coils 50 drawn from the prior art are incorporated, respectively.

Therefore, when the pair of pencil-type coil 50 is embedded, four high-voltage output terminals are formed, so that the four spark plugs IP may be directly ignited. Hereinafter, the technical idea will be described in more detail with reference to FIG. 11.

6 to 8 show the structure of the pencil-shaped coil 50 and FIG. 7 shows only the connection terminals except for the protrusions extending to both sides as bobbins for secondary coils for convenience of illustration.

The primary coil of FIG. 6 constitutes an insulator on the core 51 at the center portion thereof, wound the winding W for the primary coil, and constitutes the primary coil winding 55, and the secondary coil of FIG. The secondary coil winding body 58 is wound on the bobbin 57, and the primary coil winding body 55 is accommodated in the inner side and connected.

The low voltage input terminal of the primary coil winding 55 wound on the core 51 via insulating tape, bobbin, etc. is wired to connect the primary wiring I to the engine control module M. The terminal ring portion 53 for wiring to the terminal pin P of the connector 20 is fixed and used as the wiring portion.

The pencil-type coil 50 described above is introduced into each of the receiving holes of the coil housing tubes 2 and 3, and finished with epoxy resin, and the terminal 20 is wired to the connector 20 to the engine control module M. This is completed by connecting the output wiring for routing to the terminal body 15 in (11, 12, 13, 14).

The secondary coil bobbin 57 can be closely fitted to the inner wall surfaces of the respective coil receiving tubes 2 and 3 of the coil pack housing 1 and guide rings 57 'acting as spacers protrude on both sides. By being molded by the winding (W) therebetween it is possible to tightly insert the fixed in the coil receiving tube (2, 3).

The completed pencil-type coil 50 is hardened by injecting an epoxy resin in a state inserted into the coil receiving tubes 2 and 3 of the coil pack housing 1.

The secondary coil winding body of the terminal body 15 and the pencil-type coil 50 to form the output wiring to the terminal towers 11, 12, 13, and 14 having the terminal body 15 embedded therein, respectively. Of course, the connection terminal 60 to which the end line 60 'of 58 is connected can be wired by various methods such as brazing, resistance welding, and the like.

Another major aspect of the present invention is as shown in Figure 4e,

Open ends 2 ", 3" are formed at one end of the coil receiving tube 2, 3 of the coil pack housing 1, and the pencil coil 50 is inserted into the open ends 2 ", 3". Then, by performing epoxy resin injection (EP) with a gap G assured between the inner wall of the open ends 2 ", 3" and the outer wall of the pencil-shaped coil 50,

Since it is injected in the axial direction instead of the epoxy resin in the vertical direction with respect to the coil, it is possible to harden and fix it with a minimum amount of epoxy resin.

Outside the coil pack housing 1 of the ignition coil (IC) of the present invention is equipped with a shield plate 30 for forming a passage of the electrostatic shielding and the magnetic plus.

The shield plate 30 is formed by processing a conductive metal plate and then insulated coating, and is bent to form an outer contour of the coil pack housing 1 to form an outer contour of the coil pack housing 1. It is made to be closely connected so that there is no space | interval with a direction, and it will be installed in the middle at the time of mounting to the engine block of the coil pack housing 1, etc.

Preferably, the shield plate 30 houses the outer circumferential walls of the coil receiving tubes 2 and 3 and the connecting bridge portion 40 integrally, and both ends 30 ′ are intermediate parts of the coil receiving tubes 2 and 3. To ensure the stability of mounting and receiving

In addition, the same bushing holes 32 and 32 'as the above-described bushings 41 are drilled, respectively, so as to be interposed between the bushings 41 and the mounting part by means of the bushings 41 and fixed to the mounting portion.

In the illustrated configuration, the corresponding fitting portions of the coil receiving tubes 2 and 3 of the coil pack housing 1 at the corresponding positions are drilled and drilled through the fitting holes 30 ″ drilled at both end sides of the shield plate 30. It is more preferable from the standpoint of assemblability to form the fitting protrusions 2-1 and 3-1 so as to be fitted and fixed at both end sides.

The pack type automotive ignition coil assembly using the pencil coil of the present invention as described above can drive a plurality of spark plugs (IP) by compactly accommodating a plurality of pencil coils in one ignition coil. The applicability is very high.

In addition to the basic configuration as described above, various embodiments that can be further inferred in the present invention can be implemented, and such modified embodiments are also included in the technical scope of the present invention.

Modified Example 1

In the above-described basic embodiment, the coil pack housing 1 itself is formed by inserting a bushing 41 made of metal for mounting on the engine block into the connecting bridge portion 40.

However, such a configuration is not easy to insert and insert the bushing 41 in the correct position, and a large number of members are required, resulting in an increase in manufacturing cost.

The configuration devised therein is as in the slope view of the shield plate only showing the modified embodiment of Figs. 9 a, b, c, d, e, and f and in the mounting state of the ignition coil,

In constructing the shield plate 30B of the present embodiment,

The connector 20 is pressed into the insertion groove 21 of the coil pack housing 1 by forming and forming the fitting protrusion 22 fitted into the insertion groove 21 integrally formed on the outer circumference of the connector 20. It was configured to be fixed.

In practice, however, when the ignition coil (IC) of the present invention is to be detached from the coil pack housing (1) for repair, maintenance, or inspection in the actual vehicle mounting state where an engine block or the like is mounted,

 In order to pull out and separate the fitting protrusion 22 of the connector 20 from the insertion groove 21, a free space is required to the side, but in practice, interference between adjacent components is caused in the mounted state.

Therefore, as another modified configuration of the present invention as shown in Figure 10 b, c,

Mounting and detaching by having the inclination angle (α) upward with respect to the axis (C) of the coil pack housing (1) or by arranging the insertion groove (21) and the fitting protrusion (22) in a direction perpendicular to the axis (C). Minimize interference with side components.

In the drawings, 21 'and 22' schematically show the direction in which the insertion grooves and the fitting protrusions cooperate with each other.

Forming and configuring the fitting protrusion 22 fitted in the insertion groove 21 of the cross-sectional outline "C" shape formed in the coil pack housing 1 and the insertion groove 21 integrally formed on the outer circumference of the connector 20. Of course it can.

In the mounting of the connector 20 in this avoided position, as described above,

In view of some designs, the connectors 20 formed at the open ends 2 ", 3" of the coil receiving tubes 2, 3 of the coil pack housing 1 do not interfere with the assembly of the pencil coil 50. Since the connector 20 and the coil pack housing 1 are integrally injection molded, it may be configured.

Modified Example 3

1 to 2, but not described in detail, a modified embodiment of the basic configuration will be described.

A plate-shaped connecting bridge portion 40 is integrally formed as a member for interconnecting a pair of coil receiving tubes 2 and 3 to be disposed in the coil pack housing 1.

More specifically, the connecting bridge portion 40 was configured as a plate-shaped member having a central portion embedded therein for reducing the weight and weight of the injection molding material.

In the connecting bridge portion 40, which is a plate-like member described above, rainwater or impurities from the outside are accumulated when the vehicle is mounted on the vehicle, thereby affecting insulation properties.

In particular, when impurities such as dust containing metal powder accumulate for a long time, a significant adverse effect is caused on the ignition coil (IC) in which high voltage is induced.

Therefore, in this embodiment, as shown in Figs.

The connecting bridge portion 40 is provided with a configuration in which the drain hole 45 for discharge of rainwater or the like is integrally formed with the coil pack housing 1 at the time of injection molding as a perforated body having various shapes and numbers.

The drain hole 45 as such a perforated body has a very simple design configuration and its expected action is as described above.

Modified Example 4

The ignition coil (IC) basically provided in the present invention is configured to directly ignite the spark plugs IP of four engines by incorporating a pair of pencil-type coils 50, but as shown in FIG. As in the typical composition made,

As a change of the coil pack housing (1), three pencil coils (50-1, 5-2, 50-3), four pencil coils (50-1, 50-2, 50-3, 50-4) . . By configuring the built-in six spark plugs (IP), eight spark plugs (IP) to provide a configuration capable of direct ignition.

Therefore, the number of pencil-type coils 50 constituting the ignition coil IC may provide a configuration capable of increasing or decreasing the number depending on the type of vehicle or design to be applied.

That is, by configuring each of the ignition coil (IC) of the present invention as a module, it may be assembled to correspond to the number of the spark plug (IP) to be applied by combining or separating each module.

The pack-type automotive ignition coil assembly using the pencil coil of the present invention as described above,

It provides a highly reliable ignition coil (IC) capable of directly igniting a plurality of spark plugs (IP) and has the usefulness of reducing the mounting space and manufacturing cost.                     

It is also an important effect to provide design flexibility by enabling various modified designs.
