Definitions
- the invention relates to a device for controlling a heating element in one
- control devices which essentially comprise a switching element and a controller.
- switching means preferably transistors are used.
- transistors are used.
- Such heating elements very large currents.
- the power can be switched off very difficult with great effort. A destroyed power transistor leads to a strong heating of the control unit.
- a connecting means is at least partially designed as a built-in mechanical stress element, and the element is connected at least at a first contacting such that it dissolves when a threshold temperature is exceeded, such overheating can be safely avoided.
- a thermal fuse is completely independent of the electronics.
- FIG. 1 essentially shows elements of a control device for controlling a heating element in a motor vehicle.
- a heating element is designated 100. This is connected via a first connection 101 to a ground connection 105 in the motor vehicle.
- a second terminal 102 of the heating element 100 is connected to a first plug contact 110 of a control device 200 in connection.
- the control unit 200 is in turn connected to a second plug contact 120 with a supply voltage connection 130 of the motor vehicle.
- the controller 200 includes, among other things, at least one controller 230, which includes a
- Switching means 240 controls.
- a first terminal 241 of the switching means 240 is connected to the plug contact 120 via a first connection means 260.
- a second terminal 242 of the switching means is connected via a second connection means 250 with the first plug contact 110 of the control device 200 in connection.
- the switching means and the controller 230 are shown, with which the heating element 100 is driven.
- the control unit may comprise other components in addition to the illustrated elements. It can be provided, inter alia, that between the second terminal 242 and the first plug contact 110, a means for detecting the current flow through the switching means or the heating element is provided.
- the controller 230 controls the switching means 240 such that a desired current flows through the heating element 100 or that the heating element reaches a certain temperature.
- the heating element 100 is preferably a glow plug of a diesel internal combustion engine.
- corresponding control devices are also used for other heating elements, for example a heating element for heating a probe, for example a lambda probe.
- such heating elements can also be used for heating other elements such as a rear window heater or an auxiliary heater can be used.
- the switching means 240 is preferably designed as a corresponding transistor, in particular as a high-power field effect transistor.
- the first connection means 260 and the second connection means 250 are formed by more or less solid conductors.
- suitable sheets or other tracks are used for this purpose.
- FIG. 2 shows two advantageous embodiments of a connection means according to the invention.
- the connecting means shown in FIG. 2a is the first connecting means 260, which connects the plug 120 to the first terminal 241 of the switching means 240.
- a first part of the connection means is designated 300.
- This first part of the connection means 300 is preferably connected to the first connection 241.
- the second part of the connection means is designated 310.
- This is preferably connected to the plug contact 120 of the control unit, preferably, it may also be the plug contact 120 in the second part of the connecting means 310.
- it can be the connection pin of the switching means 240. But it is also possible that corresponding metal parts are provided, which form the first and the second connecting means.
- the first part of the connection means 300 is connected to an element 320 via a first contact 305 and that the second part of the connection means 310 is connected via a second contact 315.
- Erf ⁇ ndungs- according to the element 320 is installed so that it is under mechanical stress. This means that element 320 is only in the contacted state in the position shown. Once one of the two contacts is released, the element 320 assumes a position such that the electrical connection between the first part of the connection means and the second part of the connection means is prevented.
- the element 320 is formed as a spring, which is contacted under tension. Is one of the contacts solved, Due to the voltage, the element separates from the other contact and the current flow is interrupted.
- the first contact 305 is formed so that it dissolves when a limit temperature is exceeded. This is achieved, for example, by carrying out the first contact by soldering with a solder having a relatively low melting point.
- the second contact is carried out by means of a weld, which is only solved at very high temperatures.
- this element 320 is released from the first part 300 of the connecting means due to the mechanical stress and interrupts the electrical connection between the switching means and the plug 120.
- the component which emits the most heat loss is mounted on the resilient element.
- This is preferably the switching means. This has the consequence that, when the switching means overheat, this leads to a temperature increase of the resilient element and thus the contact. This means that at an excessive temperature of the switching means, the first contact dissolves and the current flow is automatically interrupted.
- the element 320 can occupy two positions. In a first position, the element 320 is not under mechanical tension. In this first position no current flow is possible. In a second position, the element is under mechanical tension. In this second position, electricity flows. The element is installed in the second position and held by the two contacts. At an inadmissible warming dissolves at least one of the contacts. Due to the mechanical see voltage passes the element 320 without further action in the second position and the current flow is interrupted.
- the energized element can be realized differently.
- a resilient element is used that under
- an external force acts on the element, which breaks the connection when releasing the contacting.
- external force is to be considered in particular gravity, d. H. the element is arranged below the connection means of the second part of the connection means. Dissolves the contact due to the elevated temperature, so the element moves downwards due to gravity and dissolves the connection.
- FIG. 2b differs from the embodiment according to FIG. 2a only in that the elements are arranged with reference to an acting force.
- the direction of the force effect is indicated by an arrow.
- the force can be caused by gravity. But it can also be provided that, for example, an electromagnetic
- both contacts are formed such that they dissolve when a limit temperature is exceeded. This has the consequence that when the limit temperature is exceeded, both contacts solve and the
- the procedure according to the invention is not limited to the fact that the first connection means is designed accordingly. It can also be provided that, alternatively or additionally, the second connection means 250, which connects the first connector 110 and the second connection 242 of the switching means 240, is designed accordingly. Furthermore, it may be provided that only the connecting means are partially formed correspondingly as shown in Figure 2. This is particularly useful if additional components are provided between the plugs of the controller and the terminals of the switching means. Furthermore, it can be provided that the Bond between control unit 200 and heating element 100 and between heating element 100 and ground terminal 105 and between supply voltage terminal 130 and plug contact 120 are formed accordingly.
- a plurality of heating elements are connected to a control device.
- thermal fuse is completely independent of the electronics or an external impact. Only by the mechanical bias or by a force acting from outside such as the
