Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention has a casing made of an insulating material and having a substrate and two side parts forming a cavity. This invention relates to a contactless control type Hall magnetic ignition generator for transistor coil ignition, in which a permanent magnet having a magnetically conductive plate is arranged, and an IC element is arranged on the other side.

[Prior Art] The space formed by the two sides of conventional ignition signal generators is required to remain unchanged over the entire operating period and under all operating conditions. This is because as the gap becomes larger or smaller, the connection operating point shifts to an unacceptable degree. These factors include, inter alia, temperature fluctuations, aging instability and mechanical loads in the insulation casing of the magnetic ignition signal generator.

[Purpose] The present invention aims to maintain a constant width of the air field over the entire operating period and under all operating conditions in a non-contact controlled Hall magnetic ignition signal generator for transistor coil ignition as described at the beginning. The challenge is to maintain this.

[Structure of the invention] According to the invention, the problem is to have a casing made of an insulating material having a substrate and two side parts forming an air space, in which a magnetically conductive plate is attached to one side part. In a contactless control type Hall magnetic detector for transistor coil ignition, in which a permanent magnet is arranged and an IC element is arranged on the other side, under any operating conditions of the magnetic detector,
In addition, in order to maintain a constant width of the cavity over the entire operating time, a reinforcing element with a supporting effect is embedded in the casing, said reinforcing element being made of a metal plate and made by bending and punching. wherein the reinforcing member is disposed within the substrate and on at least one side extending perpendicularly to the substrate; the one reinforcing member is arranged in an area of the substrate; Two side plates and one that connects them
and at least two plates in the region of the lateral part accommodating the IC element;
The solution is such that the plates are each arranged next to an IC element.

In the configuration of the magnetic ignition signal generator of the present invention as described in claim 1 of the utility model registration, the region of the magnetic ignition signal generator that has the greatest influence on the change in air pressure is made of a reinforcing member that can be manufactured at low cost. reinforced by. Furthermore, it has been found that the reinforcing member of the present invention satisfies the requirements for magnetic ignition signal generators.

In the embodiments of the ignition signal generator according to claims 2 and 4 of the utility model registration, the structure of the reinforcing member is particularly simple and easy to manufacture.

In the embodiment of the ignition signal generator described in claim 3 of the utility model registration, the material cost of the insulating material is reduced,
The detector can be conveniently fixed to the interrupter plate, yet both the first and second sides can be reinforced and the
The parts that influence the can be interconnected.

It is further advantageous if the reinforcing element is provided with engravings and steps in order to provide a localized support in the injection molding tool. Thereby, the reinforcing element can be embedded in the tool without additional reinforcing devices,
The reinforcing member can be sufficiently surrounded by the insulating material.

[Example] In Figures 1a, 1b and 1c, a Hall magnetic ignition signal generator for contactless controlled transistor coil ignition comprises a casing 9 with a base plate 10 made of thermoplastic insulating material; It has first and second side surfaces 11 and 12, which project integrally from the substrate 10 at right angles and form a cavity 13. The first side portion 11 includes a permanent magnet 14 having a magnetically conductive plate 15.
The second side part 12 houses, inter alia, an IC element 16 to which three lead wires 17 are connected.
have.

In Figures 1a, 1b, 1c, and 2,
A reinforcing element 18 is shown, which is made by bending and punching a metal sheet and is surrounded essentially on either side by the insulation of the casing 9. The reinforcing element 18 comprises two side plates 2 arranged symmetrically with respect to the plane 19 and connected by a web part 21 from which a trapezoidal tongue 22 projects.
It has 0. Similarly, the trapezoidal plate 23 is
Projecting integrally from each side plate 20 at a substantially right angle, the terminal end 24 of each side plate 20 is slightly angled with respect to the plane of symmetry 19.

The reinforcing member 18 is embedded in the casing 9 as follows. That is, the substrate 10 accommodates side plates 20 having webs 21, and both plates 23 are embedded in the side plates 12 such that each plate is placed next to an IC element 16.

The second embodiment of the reinforcing member 28 has two side plates 30 which are also connected by a web portion 31 . In this case, the hole 36 and the plate 3
3. Additionally, a plate 34 projects from each side plate 30. The plate 34 is the first side part 1
1, the protrusion 35 protrudes through a substrate, not shown in detail, and is used for fixing the reinforcing member 28 to the interrupter plate of the ignition distributor, not shown.

[Effects of the invention] According to the Hall magnetic ignition signal generator of the invention,
Over the entire operating time and under all operating conditions, the width of the cavity remains constant, and the unique geometry of the reinforcing element eliminates the need to change the shape of the injection molding tool for the casing at all. It may be fine, or it may only need to be changed slightly. Another advantage is that only a small amount of retrofitting time is required to convert existing mass production equipment to the magnetic ignition signal generator of the present invention.
