Description

External pushbutton for electrical equipment, especially for circuit breaker

Technical field

The invention relates to an external pushbutton for an electrical device, in particular a circuit breaker, with easy operation without the use of a tool.

io S h a n d a n c h e s

At present, it is quite common to provide electrical apparatuses with various external buttons, linked by their functions to the internal mechanism of the electrical apparatus. These are mainly various test, cut-out buttons acting inside the electric device on its release, or switching on / off the motor drive of the electric device switching mechanism, etc. The control buttons usually penetrate some parts of the front covers, are raised or flush with the front cover planes. they are recessed to a certain depth in the openings of the front covers. The buttons have different sizes depending on their functions and the space available for their placement. As the miniaturization of electrical devices progresses, the design possibilities for use are virtually reduced

2-button operation with easy finger control. since on a small electric device the button may also be only small with a small actuating surface with a lack of wheel recess and which can be operated manually, but usually only by using a hand-held tool such as a screwdriver, test tip, etc.

.5 The external pushbuttons intended for direct manual operation are, for example, partially guided through the walls of the openings in the covers on part of their path, the inner edges of the openings in the covers form any stops therefor, etc. but not in any other interaction with the covers the internal mechanism of the electrical apparatus, for example in the case of unwanted manipulation of the casing of the electrical apparatus, or in the case of mounting of the casing on an electrical apparatus which has previously undesirably brought the day to the closed state etc.

SUMMARY OF THE INVENTION

It is an object of the invention to achieve an efficient placement of the external button, in particular a test button, in the front cover of the electrical apparatus, so that even when the external dimensions of the external button or the external button are minimized. the corresponding housing of the electrical apparatus was a finger-operated button without the need for a tool and at the same time to create an interactive connection of the button to the front cover in situations where the front cover is handled, the object being achieved by the solution the button is arranged as a movable member at the edge of the hinged front cover, which includes a corner cut-out for increasing the space for multidirectional finger actuation of the outer button, the hinged front cover having an internal projection with access to the outer button; When the hinged front cover is installed / dismounted, the nearest facing portion of the rear part of the outer button 45 intersects it.

It appears to be advantageous according to the invention. This means that the head of the outer button corresponds in contour with the transverse profile of the edge of the hinged front cover and thus does not protrude in any way, yet. Due to its recess in the corner cut-out at the edge of the hinged front cover, it is easy to operate with the finger of the hand and, if necessary, together with the fixed fixed projection for descriptive data, forms a practical and visually friendly complex.

FIG. 2 is an oblique view of the electrical apparatus with the hinged front cover tilting position, whereby an internal push-in protrusion in the hinged front cover automatically acts on the outer pushbutton; Fig. 4 is a detail of the corner cut-out for enlarging the space 10 for the multidirectional finger control of the outer button; Fig. 5 is a cross-sectional view of an electrical device in the plane of the outer button sliding holder; by an electric device guided in the plane of the sliding holder of the external button with the detail of the deflected hinged front cover during the assembly or disassembly phase and the external button pressed by it.

DETAILED DESCRIPTION OF THE INVENTION

The electrical apparatus, in particular the circuit breaker, usually consists of a plurality of mutually assembled outer parts, such as a base 1, a main cover 2, terminal covers 3 and, as a rule, a front cover 4 removable from the main cover 2. the hinged front cover 4 is not intended to operate the electrical device without reason. It is usually used to open the interior of the electrical device, both during assembly and retrofit, so that the electrical device can be modified in various ways by inserting various electrical elements into the basic E monitoring the operating status of the electrical device or acting on the electrical device. As a rule, buttons are provided for manually operating the electrical apparatus, in particular by its trigger for controlling the switching system of the electrical apparatus. Among the mentioned buttons can be included an external button 5 with a test function, when pressing it acts on the trigger inside the electrical device, which then switches off.

The design and dislocation triggers within the electrical apparatus, as well as minimizing the external dimensions of the electrical panel 4, do not allow the external button 5 to be located at any point of said electrical panel 4 and create different recesses or recesses in the electrical panel 4 hand control. According to an exemplary embodiment, the outer push button 5 is therefore arranged as a movable component in the edge δ of the hinged front cover 4 (FIG. 3). The edge 6 includes a corner cut-out 7 for the outer button 5 to increase the space for multidirectional finger control of the outer button 5. The corner cut-out 7 (Fig. 4) permits deeper penetration of the fingertip and thus allows access and contact with the outer button 5 stroke. The head of the outer push button 5 corresponds in contour with the transverse profile of the edge δ of the hinged front cover 4.

According to an exemplary embodiment, the outer button 5 is provided with a sliding holder 8 which is guided longitudinally in the interior of the electrical apparatus, for example in the main housing 2 in respective cavities or grooves, of which at least a guide groove 9 is shown in FIGS. The outer push button 5 is spring-loaded by a compression spring 10 and is provided with a backstop 11 and projections (not shown) which are not shown in detail, acting on the trigger mechanism of the electrical apparatus. The outer push button 5 together with its sliding holder 8 is not removable from the body of the electrical apparatus. By means of said compression spring 40, the outer button 5 is still pressed into its basic position (FIG. 5), in which the head of the outer button 5 follows the edge 6, respectively. the transverse profile of the hinged cover 4 in this part thereof and which, together with a possible fixed fixed protrusion 12 for important descriptive data, completes it into a complete line form. The outer button 5 may be integrated in said fixed lug 12.

o.

By effectively positioning and arranging the external button 5, in particular the test button, in the hinged front cover 4 of the electric apparatus, even when minimizing the external dimensions of the respective hinged front cover 4 of the electric apparatus, interactively connecting the outer button 5 with the hinged front cover 4 in situations where the hinged front cover 4 is handled. The hinged front cover 4 is for this purpose from the inside, within reach of the external button

5. provided with a leading protrusion 11, wherein the path of the tilt front cover 4 intersects the nearest facing portion of the rear portion 14 of the outer button 5 when the hinged front cover 4 is mounted or dismounted.

As shown in FIG. 5, indicating the rest position of the outer button 5 and the hinged front cover 4 in cross-section, the leading protrusion 13 is in a position in which it is inserted behind the rear portion 14 of the outer button 5 and does not affect its basic functions. As the Fig. 6, at the beginning of the dismantling of the hinged front cover 4, which ^one after loosening the bolts 15 of (FIG. 2) may, prior to completely removing the first start vyklápčt on a not shown locking projections in the main casing 2 below the front t5 wall edge 6 impresses said the leading protrusion L3 onto the rear portion 14 of the outer button 5 and compresses them. thereby equipping the electrical apparatus (not shown) of the electrical apparatus, which is thereby switched off. The above-mentioned effect of switching off the electrical device also occurs when the front cover 4 is folded back in and folded back.
