Abstract

Control element for switching elements produced in particular by injection molding, consisting of a thermoplastic elastomer (Thermoflex), comprising at least one elastically deformable area, at least one contact area and at least one support or sealing area.

Description

The invention relates to a control element for injection molding in particular manufactured switching elements.

From DE-A 43 26 226 a toggle switch has become known with one around a supporting axis pivoted operating lever and with a first and a second - a cracking - projecting Area opposite to each other with respect to the supporting axis Tilting of the operating lever can be buckled and contact areas have the further contact areas to form a first Switch element and a second switch element opposite are arranged, the switching on and off of the first and the second switch element when buckling a crack feeling projecting areas. By arranging one the first and the second projecting protrusions Function bar bridging the area between the operating lever and the two protruding areas is when the Operating lever in one direction, the toolbar is in the same  Direction like the operating lever around the second protruding area pivoted. As a result, the first projecting area is against pressed the toolbar so that the first switch element under Generation of a first click feeling is switched on. Will the Tilting the control lever in the same direction can Toolbar does not project the first projecting area into one above it Press the outgoing position. Thus the function bar in opposite direction to the direction of movement of the Actuating lever pivoted about the first projecting area. As a result, the second projecting area is removed from the function bar Pressurized so that the second switch element under generation a second click feeling is turned on. With this toggle switch so-called switch mats come with molded elastic Elements used, the so-called within the elastic element Pick up contact pills and usually in with a circuit board Be brought into operative connection, which have equivalent contact elements.

This toggle switch is characterized by a complicated structure Realization of the desired switching functions. The manufacturing effort is large, so that such a component is not inexpensive to manufacture. The Safety mats are produced in more or less large dimensions and represent separate components, so that an increased storage effort accompanied. In the event of improper production, it can also be problematic, optimal positioning of each other opposite contact elements of the safety mat and the circuit board realize so that it after mounting the switching element on the PCB may malfunction.

The invention has for its object a control element for in particular switching elements produced by injection molding in this regard to further develop that the disadvantages of the prior art are overcome  warehousing is eliminated and the desired switching function is optimal can be executed. Furthermore, a reduction of the Manufacturing costs and a cost reduction can be guaranteed.

This object is achieved in particular by a control element Injection molded switching elements, consisting of a thermoplastic elastomer (e.g. Thermoflex) containing at least one elastically deformable area, at least one contact area as well at least one support or sealing area.

Advantageous developments of the subject matter of the invention See subclaims.

Compared to the conventional switch mat, the inventive control element consisting of a thermoplastic elastomer preferably by spraying directly into the area of the Switching element introduced and can over the molded approaches can be easily fixed, for example in the area of a printed circuit board. There if there is no separate component, there is also no need to stock them up Safety mats or elements similar to safety mats.

The control element according to the invention includes another According to the idea of the invention, different elastic ranges, wherein the support or sealing area is less elastic than that between it Area and the contact area arranged elastic area formed is.

The subject matter of the invention is based on an embodiment in the Drawing shown and is described as follows. Show it:  

Fig. 1 dimensional representation of the trigger element according to the invention in different views;

FIG. 2 shows a partial illustration of a control element according to FIG. 1 arranged on an actuating element of a control lever (not shown);

FIG. 3 representation of two interconnected control elements according to FIG. 1 in operative connection with control levers of a switching element, not shown, molded thereon by injection molding;

Fig. 4 is a representation of, the switching element made in particular by injection molding with Ansteuerhebeln including a molded thereto driving element according to the invention;

Fig. 5 installed state of the switching element in accordance with Fig. 4.

Fig. 1 shows the inventive control element 1, which is produced from a thermoplastic elastomer, in this example Thermoflex, and is by injection molding. Alternative thermoplastic elastomers are also conceivable depending on the application. The control element 1 includes a gating area 2, a contact area 3 , an elastic area 4 and a support or sealing area 5 . The elasticities of the areas 3 , 4 and 5 are chosen differently in this example, such that the contact area 3 and the support or sealing area have a lower elasticity than the elastic area 4 . Lugs 6 are formed on the support or sealing area 5 and are used to position the control element 1 in the area of corresponding components (as shown in the following figures). The elastic region 4 at least partially surrounds the contact region 3 , a conductive contact pill 8 being provided at one end 7 , which in the installed state stands or can be brought into contact with a corresponding conductive element, for example a printed circuit board. The contact is triggered as a result of deformation of the elastic region 4 relative to the support or sealing region 5 , as a result of which the contact region 3 is moved downward and the contact pill 8 can be brought into contact with the printed circuit board.

Fig. 2 shows an angled lever 9 , which can be a control lever of a switching element, not shown. The control element 1 is injected in the area of the one lever end 10 into an opening 11 provided there, so that the injection area 2 comes to rest there. The other areas 3 , 4 , 5 and the lugs 6 are equivalent to FIG. 1. The same applies to the carbon pill 8 .

FIG. 3 shows an alternative to FIG. 2, in which case two control elements 1 are connected to one another by means of a web 12 and, as already described in FIG. 2, are operatively connected to levers 9 by injection molding. The web 12 extends between the support or sealing areas 5 of each control element 1 . This measure makes it possible to implement different switching functions within a switching element (not shown further), with an exact positioning of the respective control element 1 in relation to a conductive element (not shown further).

FIG. 4 shows a switching element 13 , consisting of a housing 14 including a frame 15 formed thereon, which was produced in particular by injection molding a thermoplastic. An actuating lever 17 which can be pivoted about an axis 16 was introduced into the housing 14 by injection molding a thermoplastic material such that there is a play-free articulated connection in the region of the housing 14 . As already described in FIG. 3, control levers 9 are integrally formed on the housing 14 , each of which carries a control element 1 . In this example, no contact pills are provided, as can be seen in FIGS. 1 to 3, rather the area 18 is made of a conductive plastic, which has the same effect as the carbon pill 8 (FIGS . 1-3). The conductivity can be generated, for example, using the known MID method.

For the purpose of assembly, the control levers 9 are pivoted through 180 ° into their operative position and come into contact in the free spaces 19 to 20 of the frame 15 .

Fig. 5 shows a possible application. The housing 14 , the actuating lever 17 , the actuating lever 9 and the actuating elements 1 formed thereon can be seen. Positioning of the switching element 13 on a printed circuit board 21 takes place via the approaches 6 (not recognizable here) addressed in FIGS. 1 to 3, so that the opposing contacts on the one hand of the control element 1 and on the other hand the printed circuit board 21 are positioned exactly.
