DESCRIPTION

Switching insert of an electrical installation equipment

The invention relates to a switching insert of an electrical installation equipment with a lower housing part having at least one switching chamber, at least one switching balance cm acting pivotally supported on the lower housing part on a balancm of assigned contact of the switching chamber.

From DE 42 39 707 C2, an electrical switching device is known, especially pushbuttons or switches of parallel elevation, with a manually operated element and with a switching balance swinging supported by it for the actuation of contacts of switching, as well as with a clutch arranged between the manual drive element and the switching balance for activation and formed by a switching slide and a set of levers that engage in the switching slide. The switching slide has two sliding surfaces arranged at an angle to each other, along which one of the levers of the lever assembly alternately slides causing a variation in the length of the switching balance. The set of levers is composed of two levers arranged in a U-shape, joined together in a piece by means of a core and fixed by at least one molded part in the hand-operated element or in the switching balance.

From EP 0 746 005 A2 a switching device is known, especially a push-button, with a drive element, for example a switching balance, which after the drive returns to its initial position, with a slide activated by it with at least one pendulum fixed thereon in an articulated and tilting manner, and with a switching element for actuating at least one set of contacts that interacts with the slide and the pendulum. The pendulum joins the slide articulately in one piece, for example through a laminar hinge.

The object of the invention is to propose a switching insert of an electrical installation equipment whose lower housing part can be universally completed with the switching chamber, both for a rocker switch / rocker switch activated by means of a balance of manual operation, as for a sequential pressure switch / sequential pressure switch that can be activated via a manually operated button.

This task is solved in combination with the features of the preamble of claim 1 by providing an upper housing part that can be attached to the lower housing part, in which a movable longitudinal actuating element is driven in a driving direction towards the lower part of the housing, and guiding in the switching balance a transverse drive element that can be moved at right angles to the direction of the drive, the transverse drive element having at least one inclined surface on which it acts, in case of movement the driving direction, at least one actuating arm of the longitudinal actuating element, whereby a lateral displacement of the transverse actuating element can be caused first and then a rotation of the switching balance and, therefore, , a turn of the contact balance.

The advantages attainable with the invention consist especially in the reduction of the manufacturing costs of the switching insert since the lower housing part, including the connections for the electric cables, the contact balance, the switching contacts and the contacts for the Switching pivot pivots can be used both for the rocker switch / rocker button that can be activated and for the sequential pressure switch / sequential push button. For the realization of a rocker switch / rocker switch a switching balance is used without the transverse drive element inserted, while for the realization of a sequential pressure switch / sequential pressure switch a drive element is inserted transverse on the switching balance. It is also possible to carry out both simple switches / simple push-buttons for a single circuit and double switches / double push-buttons for two separate circuits.

Advantageous embodiments of the invention are described in the dependent claims.

Figure 1 shows a perspective view of a switching insert for a simple switch / simple push-button in the form of an exploded drawing. In the embodiment for a simple switch / simple push-button switch insert 1 is formed by the following main components:

• a lower part of housing 3 with a switching chamber (or with two switching chambers in case of double switch / double push-button, see fig. 10),

• a switching balance 10 for a simple switch / single button,

• a transverse drive element 20 movably supported on the switching balance 10,

• a top part of housing 28,

• a longitudinal actuating element 33 for a simple switch / simple push button.

The lower part of the housing 3 has two connections 4, 5 (threaded or plug connections) for electrical cables on its lower face or side surfaces. On its upper face, at least two pivot contacts 8 are provided, which interact with pivots 13 of the switching balance 10 so that a tilting movement of the switching balance 10 is possible within predetermined limits with respect to the lower housing part 3.

The switching balance 10 has a switching pin 14 on its underside that penetrates the lower part of the housing 2 and acts there on a contact balance 6 to cause switching actions (connect ON / disconnect OUT, blocking pulse - tension), as explained in greater detail in Figures 6-9. On the upper face of the switching balance 10 there is at least one housing space 16 for the transverse drive element 20.

The transverse drive element 20 has a first inclined surface 21, a second inclined surface 22, a first recess 23, as well as a second recess 24, indicating in relation to a more detailed explanation of the operation of these variants of embodiment figures 6 - 9. Also important is a spring 26 fixed within the transverse drive element 20, which allows an elastic mobility of transfer of the transverse drive element 20 within the housing space 16 of the switching balance 10 and which in the rest state causes the transverse drive element 20 move back to a position in the center (center position).

The upper carcass part 28 can fit through several interlocking elements 29 in the lower carcass part 3 and has a top 30 in its upper part to guide the longitudinal actuating element 33 that penetrates the carcass upper part 28. Springs 38 are provided between the spring housings 31 of the upper housing part 28 and the lower face of the longitudinal actuating element 33 which give rise to an elastic recoil of a longitudinal actuating element 33 pressed in the direction of the lower housing part 2 to a resting position. The retaining elements 39 provided by the lower face of the longitudinal actuation element 33 prevent a slip / brown of the longitudinal actuation element 33 of the groove 30 of the upper housing part 28. Two actuating arms 36, 37 are considered important provided by the lower face of the longitudinal drive element 33 and which interacts with the transverse drive element 20 (see in this regard Figures 6-9).

In figure 2 an electrical installation equipment 46 is shown in the form of a simple switch / simple push-button, formed by the switching insert 1 which is completed with a central disk 41, a manually operated button 42 disposed within the central disk 41 at its center, which collaborates with the longitudinal actuating element 33, for simple switches / simple push-buttons and with a covering frame 45.

A switching insert for a simple switch / simple push-button in which the lower housing part 3 joins the upper housing part 28 is illustrated in FIG. 3. The longitudinal actuating element 33 elastically mounted and can be recognized. mobile in switching insert 1.

Figures 4 and 5 show a view on a switching balance for a simple switch / simple push-button and a perspective view thereof. Switching balance 10 has two accommodation spaces 16, however, only a transverse actuating element 20 is elastically and movable in a housing space.

several gma / clamping ribs 17 are provided. For fixing the spring 26 formed in the form of a spiral spring in the transverse drive element 20, the latter is provided with two opposite supports in the form of a rod 25.

Inside the housing space 16 of the switching balance, spring stop surfaces 18 are arranged between which the spring 26 can be moved. When the transverse drive element 20 is removed from its resting position, see the double arrow defining the two possible lateral movement directions, the spring 26 is pressed against one of these spring stop surfaces 18 and the spring 26 is compressed. Therefore, the spring 26 has the tendency / function to redirect the transverse drive element 20 always to its resting position as soon as possible.

The essential components of the transverse drive element 20 are the two inclined surfaces 21, 22 as well as the two recesses 23, 24.

Figures 4, 5 also illustrate the two pivots 13 necessary for the rotation of the switching balance 10, which fit the pivot contacts 8. In Figure 5, the switching pin 14 can also be seen.

In Figures 6, 7, 8, 9, side cuts of the switching insert are shown to explain the operation of the switching insert 1 in view of a switching process. Figure 6 shows as a starting position a switch connected (closed), that is, a closed circuit of connection 4 is obtained with its contact

switching 4 located in the switching chamber, which comes into contact with the switching contact of the

contact balancm 6 and also through the support of contact balancm 6 (balancm housing) that

leads to connection 5. Switching balance 10 tilts to the left, so that the plunger of

Switch 14 is located to the right of the balance bracket. By means of a spring 15 it is indicated that the switching pin 14 is gma / retained elastically within the switching balance 10. The transverse actuating element 20 is in its resting position in a central position relative to the switching balance. 10, which is due to the spring 26. The two spring supports 25 that fit into the spring 26 of the transverse drive element 20 can be seen.

The longitudinally driven member 33 elastically guided in the upper housing part 28 is in its resting position with the spring 38 relaxed. Accordingly, the two drive arms 36, 37 are decoupled from the inclined surfaces 21, 22 and from the recesses 23, 24 of the transverse drive element 20.

In the next switching action the switch must be opened (disconnect OUT). For this purpose, a pressure is exerted against the force of the spring 38 on the longitudinal actuation element 33 in an actuation direction A towards the lower housing part 3, which is done by activating the manual actuation button 42. First The configuration shown in Figure 7 takes place, in which the drive arm 36 slides along the inclined surface 21, resulting in the transverse drive element 20 being deflated, in relation to the switching balance 10, to the left, see arrow B. At the same time the spring 26 pressed against the spring stop surface 18 is compressed.

Overcoming the force of the spring 38, a pressure is also exerted on the longitudinal drive element 33 in the direction of drive A towards the lower housing part 3. As a consequence, the spring 38 is further compressed and the drive arm 37 penetrates the recess 24, as shown in Figure 8. Caused by the drive arm 36 located at the base of the inclined surface 21, a rotation movement of the switching balance 10 around its axis of rotation occurs (pivot 13 / pivot contacts 8 ), that is, the switching balance 10 tilts to the right (clockwise), as indicated by the arrow C.

Then the switching bolt 14 slides to the left beyond the balance support, so that the contact balance 6 makes a left turn movement (counterclockwise, which causes the opening of the switching contact, that is, the elevation of the contact balance 6 of the switching contact 7. The transverse drive element 20 remains in its offset position to the left, locked as a consequence of the drive arm 37 that penetrates the recess 24 The circuit of connection 4, through contact balance 6, to connection 5 is interrupted.

After no pressure is exerted on the longitudinal actuation element 33, the resting position shown in Figure 9 is produced with the switching contact open, in which the spring 38 relaxes by pressing the longitudinal actuation element 33 upwards, see arrow D, and in which the spring 26 also relaxes, whereby the transverse drive element 20 moves, in relation to the switching balance 10, to the right to a central position, see the arrow E. The longitudinally driven element 33 elastically guided in the upper housing part 28 is then again in its resting position with the spring 38 relaxed. consequently, the two drive arms 36, 37 are again decoupled from the inclined surfaces 21, 22 and from the recesses 23, 24 of the transverse drive element 20.

When a pressure is re-exerted on the longitudinal drive element 33, the force of the spring 38 in a drive direction A towards the lower housing part 3 being overcome, the switch closes in the next switching action (connect ON).

Figure 10 shows a perspective view of a switching insert for a double switch / double push-button in the form of an exploded drawing. In comparison with the simple switch / simple button, the following changes are observed:

• the lower part of housing 3 has two switching chambers with separate contact rocker arms 6 and the necessary connections for electric cables,

• the lower part of housing 3 together has four pivot contacts 8 for the support of two separate switching rockers 11, 12,

• each switching balance 11, 12 is provided with a transverse drive element 20 including a separate spring 26,

• two separate longitudinal drive elements 34, 35 are grounded in the upper housing part 28.

FIG. 11 shows an electrical installation equipment 47 in the form of a double switch / double push button formed by the switching insert 1 which is completed with a central disk 41, manually operated buttons 43, 44 arranged inside the central disk 41 and that collaborate with the longitudinal actuating elements 34, 35 for double switches / double pushbuttons and with a covering frame 45.

Figure 12 shows a switching insert for a double switch / double push button in which the lower housing part 3 joins the upper housing part 28. The two longitudinal actuating elements 34, 35 can be seen mounted on elastic and mobile shape in the switching insert 1.

A view of the two switching rockers and a perspective view of the two switching rockers for a double switch / double push button are presented in Figures 13 and 14. Each of the two switching rockers 11, 12 has a housing space 16 in which both transverse drive elements 20 are gripped / held elastically and mobilely. For guiding / securing the transverse drive elements 20, they provide several guiding / retention ribs 17. For fixing the springs 26 configured in the form of a spiral spring in each of the transverse drive elements 20, these are provided with opposite spring supports in the form of a rod 25. For the movement with independent rotation each switching balance 11, 12 has two pivots 13.

In the foregoing explanations in relation to operation, a bistable switching device is used, that is, the contact balance 6 is in a position to adopt two stable switching positions to thereby allow a permanent ON / disconnection OUT connection. In a further refined variant, a monostable switching device can also be used in the same way that can be used as a push-button, that is to say, in said embodiment variant the contact balance 6 always returns to its resting position, which corresponds, for example, to the position of "Disconnection OUT", after activation by means of the longitudinal drive element 33. The "connection ON" position is adopted only for a short time during the activation of the drive element 33, to thereby cause a pulse of pulsation - tension. In an embodiment such as this, the transverse drive element 20 only has to have an inclined surface 21 and a recess 24. In any case, the transverse drive element 20 necessary for the bistable switching equipment can also be used for the stable switching (push button), which advantageously results in a reduction of the necessary components.
