Definitions
- Electrical control module with light guide for receiving at least one incandescent lamp
- the invention relates to an electrical control module in which the current state of this module is indicated via one or more windows in the front panel of this module.
- This state can be, for example, a switching state or the display of the position of an actuator.
- the state can also relate to a functional state of an assembly downstream of the module.
- modules which are preferably, but not necessarily, switches are known from the prior art.
- US Pat. No. 3,518,386 shows a light guide which is illuminated by an incandescent lamp and which consists of a sum of individual light guides which lead to separate switches.
- DE-OS 27 23 692 where the windows are illuminated directly by the incandescent lamp without using an optical fiber.
- the button of a toggle switch is provided with two light guides which, depending on the position of the button, lead the light of an incandescent lamp either to one or the other wire and thus to its exit window.
- the invention is therefore based on an electrical control module of the type resulting from the preamble of claim 1.
- the object of the invention is to reduce the space requirement of this module by a particularly expedient design of the light guide.
- this module should not only be able to represent different switching states, but should also be particularly easy to assemble.
- the invention therefore consists in equipping the light guide with at least one incandescent lamp and, if necessary, in the various windows with the light guide Depending on the module status.
- the mechanical assignment of the incandescent lamp in the light guide clearly defines its important assignment. At the same time, there is no need to separately mount the incandescent lamp and light guide within the module.
- a particularly expedient embodiment of the module according to the invention results from the combination of features according to claim 2.
- one of the windows is illuminated directly by the incandescent lamp, while part of the light emitted by the incandescent lamp is transported to the second window.
- the light guide it is thus possible for the light guide to cover the incandescent lamp only from one side and thus to hinder the ventilation of the incandescent lamp only slightly.
- the burning of the incandescent lamp itself can indicate the activation state of the module and the radiation transported via the light guide in the second field can show a special form of the activation state as possible states of the module.
- the first window indicates that the lighting of a motor vehicle is switched on
- the second window indicates whether a key is depressed and thus high beam or low beam is switched on.
- Another possible application for the module according to the invention can be to simplify the search for the module within the otherwise unlit panel by switching the vehicle lighting on and to use the second window to switch on the functional state of the module ( Speed post, traction control or automatic clutch switched on or off).
- a configuration according to the combination of features according to claim 3 is particularly suitable.
- first incandescent lamp to include at least one further incandescent lamp in the light guide.
- the functionally illuminated fields e.g. second field and third field
- the second field indicates the operability of a switch
- the third field shows the function triggered by the operation of the switch.
- the combination of features according to claim 5 is recommended in a further development. Since a particularly large luminous flux is transmitted in the part of the light guide that is hit centrally by the incandescent lamp, a mechanical connection between the light-transmitting light guide and the version of a light bulb to be shielded is simultaneously provided in the If light guides are to be achieved, the combination of features according to claim 6 is proposed in an advantageous further development.
- the module according to the invention can also be used in many ways, for example in a panel for motor vehicles.
- the combination of features according to claim 9 is recommended, in which the modules provided with the base part can be snapped into the associated receptacle of an operating bar of the motor vehicle.
- the module according to the invention is comparatively simple to assemble due to the incandescent lamps integrated in the light guide.
- the use of the combination of features according to claim 10 is particularly favorable.
- a receptacle 2 is used in a receptacle plate 1 of a motor vehicle by means of a suitable detachable connection, which receptacle is used to hold a module 3 according to the invention.
- the module itself consists of a base part 4, which is snapped into the receptacle 2 by means of two opposite catch springs 5.
- a circuit board 8 having connecting lines is latched, with supports and / or connecting pieces 10 projecting from the base plate opposite the circuit board the base plate is kept at a distance.
- a light guide 11 is applied to the circuit board and fastened to it, for example by clamping or snapping on.
- latching noses of the light guide can engage in corresponding recesses in the circuit board.
- Another possibility for fixing the light guide on the circuit board is to use clamping bolts 21 which protrude into assigned openings in the circuit board 8.
- the light guide 11 is equipped with two light bulbs 12, 13 so that the light guide
- a front plate 14 is connected in a latching manner after the populated circuit board has snapped in, so that the front plate is removed from the bottom part, e.g. to replace the light bulbs or the entire board 8, can be removed.
- a first window 15 made of transparent material is cast in the front plate 14, the first window 15 being arranged in such a way that it is firmly illuminated by the direct radiation of the incandescent lamp 12.
- a push button 18 which can be moved against the force of two return springs 25 so that this button can be pressed into the front plate 14.
- the pushbutton 18 has a second window 16 and a third window 17, the second window 16 due to the radiation of the incandescent lamp which is guided through the light guide 14
- the third window 17 is illuminated by the second light bulb 13, which is also carried by the light guide 11.
- Incandescent lamp 13 is used in itself to display a switching function in third window 17.
- the push button 18 is designed as a latching button, the constellation is also conceivable that the incandescent lamp 13 is dispensed with and the radiation coming from the light guide is measured, which radiation acts via a diaphragm and is movable with the push switch 18 Wall 19 (depending on the position of the push button 18 to an extension 20) is let through or not.
- Another possibility is to use an extended wall connected to the pushbutton 18, such as the wall 19, for the second incandescent lamp . 13 to emit radiation emitted to the light guide 11 as a function of the position of the pushbutton 18, so that when the incandescent lamp 12 is switched off the second window 16 is illuminated as a function of the position of the pressure switch 18.
- An advantage of the invention is, inter alia, that the light guide made of plastic serves at the same time for the insulation of the lead wires for the light bulbs 12 and 13.
- the light guide 11 can additionally be secured relative to the board 8 by a soldered connection between a connecting line on the board 8 and the leads 23 of the incandescent lamp.
- the latching lug 24 of the light guide serves to snap it onto the circuit board 8.
- Lateral support walls 30 of the windows 15 and 16 serve to increase the light absorption of these windows, since the luminous flux additionally captured by the walls is emitted through the windows 15, 16 ⁇ can. Furthermore, it is possible that the pushbutton 18 is provided with a projection which extends past the circuit board and into the vicinity of a base plate 26 of the base part 4, by which projection a switch mounted on the base plate 26 can be triggered directly by the pushbutton 18.
