Definitions
- Residual current circuit breaker or residual current device Residual current circuit breaker or residual current device
- the invention relates to a residual current circuit breaker or a residual current circuit breaker, with a switch for switching on and off the switch, which can be pivoted between an ON position and an OFF position, and with a test button which can be pressed from an OFF position into an ON position of the test button is, in which a test contact is closed, so that a test current flows.
- the test current is used to test a device function.
- the test current takes the place of a true fault current.
- test buttons must, because they are to be operated by an operator, in an operating range of the residual current circuit breaker (also: RCCB) or residual current circuit breaker (also: DI circuit breaker) may be arranged.
- the operating area covers a range of 45mm x 18mm for standard devices, which occupy a so-called graduation unit. In this operating area, the handle must be located next to the test button and there should be room for the labeling. The labeling is necessary to provide an operator with characteristics of the fault or residual current circuit breaker.
- test button In order to provide as much space for the label, one might tend to place the test button near the handle. However, there is a risk that the test button is accidentally depressed when the handle is actuated. Such operating errors should be avoided. It is an object of the invention to develop a fault or residual current circuit breaker of the type mentioned in such a way that the space in the operating area is used as optimally as possible.
- test button is arranged so that, in the OFF position of the handle of the handle, it is at least partially concealed by an operator (and in particular is not operable thereby).
- the invention is based on the recognition that testing with the test button is in any case meaningful only when the handle is in the ON position. What happens in the OFF position of the handle with the test button is thus not relevant for their meaningful use.
- the test button is placed in the direct swivel range of the handle in the region of its OFF position, not away from the handle, which provides room for labeling in an operating area of the residual current or residual current circuit breaker. It does no harm if the test button is not actuated as long as the handle is in the OFF position, the partial occlusion of the test button may be due to the fact that the test button is not actuated, or whereby other mechanisms the inoperability of the Can pull test button with you.
- the handle snaps back from its ON position to the OFF position when the test button is pressed.
- the circuit breaker preferably has a blocking element which can be moved with the test button when the test button is depressed to the ON position, the handle is locked so that it can not return to its OFF position from its ON position (in which it is necessarily located when the button is depressed).
- the handle in its OFF position depresses the test button in the direction of its ON position, and that a spring presses the test button in its OFF position when the Handle is in its ON position.
- test button is thus something out when it should be operable, which simplifies the operation. On the other hand, it disappears under or next to the handle to save space when it is in the OFF position and therefore pressing the test button would not make sense anyway.
- the possible interaction of the handle with the test button can be achieved by the following, a compact design enabling mechanism:
- the handle has a rotatable roller.
- a recess is formed in the roller.
- a body attached to the test button is guided on which a pin is formed, which engages in the roller.
- the actual test button can be arranged next to the roller, while the actual mechanism is located above the attached body in the recess.
- the pin engaging in the roller cooperates with an inner contour surface of the roller.
- Rotation of the roller affects the inner contour surface on the pin and thus on the attached body and the test button and then just pushes down if necessary.
- the pin can advantageously act simultaneously as the above-mentioned blocking element. So he is simply pressed down with the test button, past a thickening of a roll wall. Due to the thickening, the roller no longer turn the wall around the pin. The roll wall forms in its interior the above-mentioned inner contour surface.
- the handle may also interact with the test button via a recess.
- the recess should be formed as a counter contour to a contour of the test button. The handle then partially surrounds the test button over the recess in the OFF position and holds the test button depressed against the force of the spring.
- the spring may be formed as an approach to a torsion spring, which pushes back the handle in the OFF position.
- a torsion spring is usually provided anyway and is supported by a first rod-shaped projection on the housing. If the first rod-shaped projection in turn continues through a second rod-shaped projection, in particular perpendicular to the first rod-shaped projection, this second projection also acts as a spring due to the support in the housing. Thus, it is not necessary to provide two separate housing supports for the test key spring and the torsion spring.
- the spring comprises a contact point which, upon depression of the test button in its ON position, is pressed against a mating contact point to close the test contact, the test current then flowing over the spring.
- the spring has the dual function of providing the spring action on the one hand and of replacing an otherwise necessary independent contact element on the other hand. As a result, the total number of necessary components is reduced, and thus costs are saved.
- FIG. 1 shows a perspective front view of a circuit breaker according to a first embodiment of the invention
- FIG. 2 shows a perspective inside view of the circuit breaker from FIG. 1 in the switched-on state with the test button not pressed down
- FIG. 3 shows a section through the circuit breaker from FIG. 2
- FIG. 4 shows a section through FIG. 3 corresponding to FIG
- FIG. 5 is a perspective view corresponding to FIG 2 of the circuit breaker of Figure 1 in the off state
- FIG 6 is a Figures 3 and 4 corresponding section through the switched-off circuit breaker of Figure 5
- FIG. 7 is an inside perspective view of a second embodiment of the invention in the on state
- FIG 8 is an inside perspective view of the second embodiment of the invention of FIG 7 in the off state.
- a ground fault circuit breaker designated as a whole by 10, comprises a control surface 12.
- a handle 14 is formed on the control surface and can be pivoted between an ON position shown in FIG. 1 (see “I") and an OFF position (see “0") , Furthermore, a test button 16 is accessible from the operating surface 12 forth.
- the handle 14 is formed on a roller 18, and it can be clearly seen from FIG. 1 that the test button 16 is arranged directly beside this roller 18. If the handle is in its OFF position (compare the "0" in FIG. 1 or also FIG. 5 and FIG. 6), the test button 16 for an operator is completely covered by the handle 14. This is not disadvantageous because the Test button 16 must be accessible only in the on position of the handle 14 shown in FIG 1, which is also the case.
- the arrangement of the test button 16 next to the roller 18 but has the advantage that on the control surface 12 extra space for a (not shown in Figure 1) label remains, whereby the operator characteristics of the residual current circuit breaker can be provided.
- the residual current circuit breaker 10 is also built very compact, as is apparent from the inside of the residual current circuit breaker 10 representing FIG 2 to 6. This is made possible in particular by a recess 20 in the roller. In this recess 20 engages an attached to the actual test button 16 body 22 a. Attached to the attached body 22 is a (metal) bridge 24. When depressing the test button 16 together with the recessed body 22, the bridge 24 is pressed down with and bridges a first contact 26 and a second contact 28, so that a circuit can be closed. This allows a test current to flow, which takes the place of a fault current during testing. The remaining circuitry, which is not explained in the figures, does not differ from that of conventional residual current circuit breakers. By providing the recess 20 in which the attached body 22 engages, the bridge 24 is not located below the test button 16, as it would otherwise, but below the roller 18, whereby space is saved.
- the test button should, when the handle is in the ON position, take a rest position and is forced into this by a spring.
- a torsion spring 30 is available, whose real task is to spring 18 and thus the handle 14, so that the handle 14, as soon as it leaves the ON position, is forced into the OFF position.
- the torsion spring comprises a first rod-shaped projection 32 which is supported in the housing (not visible in FIG. 2).
- the first approach 32 is not different from approaches as they are Torsion springs are common.
- the first lug 32 transitions into a second, second lug 34, which kinks perpendicularly away from it. This results in an L-shaped element on the torsion spring 30.
- This second projection 34 is in a cavity 36 of
- Test button 16 supported. This is (in Figure 2 "front”) cuboid and then widens funnel-shaped (in Figure 2 "backwards”).
- the second projection 34 On one wall of the cavity, the second projection 34 is supported. If the test button 16 is pressed down, the second projection 34 of the torsion spring 30 is tilted obliquely relative to the first projection 32, whereby the actual spring force is generated. The latter pushes the test button 16 back into the position according to FIG. 2 when the operating person no longer exerts any further pressure.
- a pin 38 is arranged on the attached body 22. While the attached body 22 engages the recess 30, the pin 38 engages under a wall 40 of the roller 18.
- the wall 40 is thickened at a location 42, in the present case at its end. The thickened portion 42 of the wall 40 does not prevent the pin 38 from moving downward when the button 16 is depressed, see FIG. 3 and FIG. 4.
- the thickening 42 is chosen to provide rotation of the roller Prevents, because the thickening 42 abuts against the pin 38 with a rotation of the roller 18 in the counterclockwise direction, starting from FIG 4 (with depressed test button 16), so that the handle 14 can not leave the ON position.
- the pin 38 has advantageously also another function.
- the test button 16 is not triggered by a depressed when the handle 14 pivots into the OFF position, because the handle 14 prevents just an operator access to the test button 16. It is advantageous, however, when the test button 16 is in the depressed position when the handle 14 reaches the OFF position, so that the test button does not have to be given too much space.
- the attached body 22 and thus the test button 16 is now depressed when turning the roller 18: a free space 44 formed by the wall 40 ends at a radial strut 46 of the roller 18.
- the inner contour surface of the roller (inner contour the wall 40 and the pin 38-pointing contour of the strut 46) is formed so that the pin 38 is initially subjected to a rotation of the roller 18 from the situation of FIG 3 counterclockwise no force effects, but remains in the space 44. Finally, however, the radial strut 46 comes into abutment with the pin 38 and leads it with the rotation of the roller 18 with it in the downward direction. As a result, the attached body 22 is pressed with the test button 16 down, see FIG 5 and FIG 6. In the present case, the test button 16 is pressed only in the direction of the ON position, and not completely in its ON position, so that the bridge 24 the Contacts 26 and 28 are not bypassed when handle 14 is in its OFF position.
- test button 16 can also be pushed completely into its ON position. In the present case, however, the path of the test button 16 in the direction of its ON position is sufficiently far enough that sufficient space is created for the handle 14, which occupies the OFF position.
- FIGS. 7 and 8 show a second embodiment of a residual current circuit breaker 10 'according to the invention.
- the structure here is the same as in the residual current Circuit breaker 10 (see FIG 2 with 7).
- the handle 14 is formed on a roller 18.
- This has a recess 20 in which an attached body 22 'of a test button 16' is formed.
- a pin 38 is mounted, and the structure of the roller 18 is otherwise the same as in the residual current circuit breaker 10 so that the roller can interact with the pin 38 in the manner described.
- the residual current circuit breaker 10 ' differs from the residual current circuit breaker 10 in that the test button 16' is not formed flush with the edge of the residual current circuit breaker housing, but that an additional housing wall 48 is provided in the residual current circuit breaker 10 '.
- the type of contacting and the suspension of the test button 16 'differs from that in the residual current circuit breaker 10 to spring the test button 16' is no longer a torsion spring used, but a separate spring element 50 which engages the attached body 22 '.
- the contact to be closed when the test button 16 'is depressed is no longer closed by means of a bridge in the manner of the bridge 24, but the spring 50 is itself live and later energized.
- a contact point of the spring 50 (in FIG. 7 and FIG. 8 respectively covered by the attached body 22 ') is pressed against a contact surface 52 as a mating contact point when the test button 16' is pressed down, whereby the circuit is closed and the test current flows.
- This embodiment is advantageous because the spring 50 is used twice. It is incidentally independent of the fact that the test button 16 'is limited by a housing wall 48, and could also be used in the first embodiment in a modification thereof.
- the residual current circuit breaker 10 ' is still different from the residual current circuit breaker 10 by a third feature: on the handle 14 is in the transition region of the handle 14 to Roller 18 a recess 54 is provided. This encompasses the test button 16 'when the handle 14 is moved to its OFF position and presses the test button 16' down. In particular, in FIG 8 then the upper wall 56 of the recess 54 acts directly on the surface of the test button 16 '. The test button 16 'is pressed completely down in the case of FIG. 8, so that the contact from the spring 50 with the contact surface 52 remains closed. This is possible with the residual current circuit breaker 10 'through the remainder of the circuitry which prevents current from flowing when the handle 14 is in the OFF position. Again, it may be provided that the test button 16 'does not fully reach its ON position.
- both embodiments of the invention, the residual current circuit breaker 10 ( Figures 1 to 6) and the residual current circuit breaker 10 '( Figures 7 and 8), have the advantage that by skillful placement of the test button 16 or 16' a compact design is possible, see in particular also the above descriptions for the recess 20 of the roller 18 and the attached body 22 and 22 '. As a result, a large amount of space for possible labeling is obtained on a control surface (cf. control surface 12 in FIG. 1).
