DETAILED DESCRIPTION

[0040] FIG. 1 shows an actuator housing 12 with a plug housing 14, formed thereon, of a signal generator according to the invention. The plug housing 14 comprises a receiving portion 16, for receiving a switch 22 with electrical contacts 20, and comprises a connecting portion 18, into which the electrical contacts project for the connection to an electric drive, for example, as will be discussed in more detail further below. The plug housing 14 may be formed on the actuator housing 12 in particular in an injection molding process. Likewise, the actuator housing 12 may be formed on the plug housing 14. This may be performed after production of the actuator housing 12 and subsequent integral formation of the plug housing 14 or after production of the plug housing 14 and subsequent integral formation of the actuator housing 12, or by means of joint manufacture of the actuator housing 12 with the plug housing 14 as one piece, in particular by injection molding.

[0041] The illustration in FIG. 2 likewise shows the unit, which can be seen in FIG. 1, composed of plug housing 14 and actuator housing 12, but only in certain portions and in a different plan view. The further production of the signal generator will be described below with reference to FIGS. 3 to 7. In the present embodiment of the method, after the integral formation of the plug housing 14 and of the actuator housing 12 on one another, a lead frame 19 composed of metal is firstly inserted into the receiving portion 16 of the plug housing 14. The lead frame 19 has the two electrical contacts 20, which are however still connected to one another by transverse webs 21. The lead frame 19 is inserted into the receiving portion 16 of the plug housing 14 such that the electrical contacts 20 project into the connecting portion 18 (visible in FIG. 10). In a subsequent production step, which can be seen in FIG. 4, the transverse webs 21 are severed, and the separate electrical contacts 20 are thus produced.

[0042] Subsequently, the switch 22 is inserted into the receiving portion 16 of the plug housing 14, as can be seen in FIG. 5. Here, the switch 22 projects in particular with a triggering element 24 out of the receiving portion 16. At least the electrical contacts 20 of the switch 22 are however received entirely in the plug housing 14, one part in the receiving portion 16 and the other part in the connecting portion 18. The electrical contacts 20 are electrically connected to the switch 22 by means of plugged-in conductors. The contacts 20 are in each case in one piece and, firstly, form the contact for the plug connection and, secondly, are plugged onto the switch 22 by being plugged in each case onto an output contact lug 23, which projects out of a housing in which the switch 22 is received as a module. The switch 22 has in each case one clip structure 23.1 at these connection points 23, and the electrical contacts 20 are plugged into the respective clip structure 23.1.

[0043] Secondly, a door lever 30 as actuator is inserted into the actuator housing 12. The door lever 30 is mounted in the actuator housing 12 so as to be pivotable about an axis of rotation D, and acts on the switch 22 in a manner to be discussed in more detail further below. The door lever 30 can be clearly seen in particular in FIG. 9.

[0044] Finally, the receiving portion 16 of the plug housing 14 is filled with a potting compound 26, as can be seen in FIG. 7. The contacts 20 of the switch 22 are thus fixed and sealed in the plug housing 14. In particular, the potting compound does not ingress here into the connecting portion 18. By means of such a potting compound, it is furthermore possible to omit a lid that closes off the receiving portion 16.

[0045] In FIGS. 6 and 7, the door lever 30 is in a non-deflected state. An actuating portion 32 of the door lever 30 consequently does not actuate the switch 22. The switch 22 is thus situated in an open position. As a result of a pivoting of the door lever 30 about its axis of rotation D out of the plug housing 12, as can be seen in FIGS. 8 to 10, the actuating portion 32 of the door lever 30 is adjusted toward the switch 22 and thus pushes the triggering element 24 into the switch 22. In this way, the switch 22 is closed, and an electrical connection between electrical contacts 20 is produced.

[0046] Owing to the integral formation according to the invention of the plug housing 14 and of the actuator housing 12 on one another and the subsequent insertion of the switch together with electrical contacts into the plug housing 14, the production of the signal generator is simplified in relation to known signal generators. Owing to the electrical contacts situated in the plug housing, it is furthermore easily possible for an electric drive that is to be connected to the signal generator to be directly mounted onto or inserted into the plug housing.
