Definitions
- the invention relates to a rocker switch for a switch fuse unit according to the preamble of claim 1 and to a switch fuse unit according to the preamble of claim 11.
- Switch fuse units of this type as well as shift paddles used in them, in whose fuse plugs fuse inserts can be used, are used in a variety of designs both in private and in commercial buildings, in particular in buildings in which machines are operated electrically. It is also possible to use switch fuse units or components such as the rocker switch directly for the electrical protection of electrically operated machines on or in machine elements or housings.
- a switch fuse unit with a rocker switch of this type is known for example from DE 34 06 815 C2.
- Such switch fuse units are used to automatically interrupt the circuit and thus the electrical supply to machines and devices when the current or the power in the circuit exceed a certain fixed value.
- fuse inserts with different characteristic values can be inserted in the switch fuse units or in the fuse plugs exhibit .
- switch fuse units serve the purpose of reliably interrupting the circuit manually, in particular when repairs to the electrical devices and machines are necessary.
- the rocker switch which contains the fuse plug with the corresponding fuse link, and which is pivotably mounted between a switch-on position and a switch-off position in a housing of the switch fuse unit, is adjusted to its switch-off position.
- the fuse links used in a circuit breaker unit are usually fuses that may be defective or melted due to excessive loads, it is advantageous to monitor the functionality of the fuse link with a monitoring device.
- Monitoring the functionality of the fuse link includes monitoring possible defects in the fuse link itself as well as monitoring poor contacting of the fuse link in one
- a monitoring circuit which bridges the input and the output of the switch fuse unit in addition to the main circuit running through the fuse link via a very high-resistance connection.
- a lamp is normally integrated in the monitoring circuit as a monitoring display.
- the arrangement of the display in the rocker switch integrates the display very well into the structural design of the switch protection unit without requiring additional space.
- the display can be integrated in the rocker switch, so that it is protected from the outside and damage is avoided.
- the rocker switch is a significantly less wear-resistant part than the fuse plug. This noticeably increases the expected service life of the control display compared to an accommodation in the fuse plug.
- the positioning in the rocker switch has the particular advantage that a more compact design of the switch fuse unit is possible.
- Installation in the housing would require an increase in the height of the housing beyond the area of the rocker switch in order to accommodate the control display in the housing.
- a lateral arrangement of the control indicator in the housing would have the consequence that the switch fuse unit would assume larger dimensions in this direction, and that disadvantages would have to be accepted when installing the switch fuse unit, since further areas of the switch fuse unit are visible, i.e. should not be covered by other elements.
- an installation of the switch fuse unit in which only the minimal area around the operating handle of the rocker switch is visible, is very desirable, especially for optical reasons.
- an arrangement of the control display in the housing means that it is visible both in an on position and in an off position of the rocker switch. Since the monitoring circuit must be interrupted in the switch-off position for safety reasons, the control indicator in the switch-off position does not light up, regardless of the functionality of the fuse link. It is therefore possible that the untrained operator in particular is irritated by the non-illuminated monitoring display in connection with an interrupted circuit in the switched-off position and possibly unnecessarily exchanges functional parts, in particular a functional fuse link. Such an irritation of the Operator is avoided by the arrangement according to the invention if the control display is not visible to the outside in the switch-off position.
- control display is arranged in an inner region of the rocker switch. This protects the control display so that no damage, be it through external intervention by the operator or through contact with other parts of the switch fuse unit, is avoided.
- the display is preferably arranged behind a transparent window, or the rocker switch is at least partially made of transparent material, behind which the control display is visible to the outside.
- control display should not be impaired by the arrangement in the interior of the rocker switch, in particular e.g. the above-mentioned window or sections of the rocker switch are opened to allow access to the control display if necessary.
- control displays generally have an extremely long service life and the on-time that determines the service life is short, such exchanges are only extremely rarely necessary, so that the control display can be replaced in favor of a simpler design.
- control display in the vicinity of an operating handle, in particular on the side of the rocker switch facing the switch-off position.
- the control display is in a central, clearly visible position when the rocker switch is in the on position, while it is automatically covered by parts of the housing as soon as the rocker switch is in its off position. This eliminates the need for additional covering devices, which leads to a simple structural design of both the rocker switch and the switch fuse unit leads.
- the rocker switch also includes devices for the monitoring circuit, in particular contact elements, advantageously spring elements, which close the monitoring circuit when the rocker switch is in the on position and interrupt the rocker switch in the off position.
- contact elements advantageously spring elements
- the devices for the monitoring circuit are also advantageously arranged inside the rocker switch, preferably in the area of the control display.
- the interior is essentially closed and has only contact openings so that the contact elements arranged in the housing can be contacted.
- the contact and / or connection elements which contact the devices for the monitoring circuit in the switched-on position of the rocker switch are preferably elements of the main circuit. This avoids the need to provide additional elements. This reduces the costs and susceptibility to errors of the switch fuse unit.
- At least one contact device preferably a spring device, which is in contact with at least one contact element of the monitoring circuit when the rocker switch assumes its switch-on position.
- Fig. 1 is a cross-sectional view of an embodiment of a switch fuse unit with a rocker switch in the on position and
- FIG. 1 shows an embodiment of a switch fuse unit 1 with a housing 2 and a rocker switch 30 in the switched-on position.
- a fuse plug 10 is inserted, which receives a fuse link 20.
- the fuse link 20 is connected to an input and an output by contact elements 70, 71, 72, 73, so that the main circuit is closed.
- the fuse link 20 is pressed by a spring device 98 against the direct contact elements 70 or 71 and 72.
- the contact element 70 designed as a spring essentially fulfills three functions.
- the electronics arranged in the circuit breaker unit are contacted via the contact element 70.
- the element 70 designed as a spring holds the fuse link 20 in the desired position relative to the fuse plug 10 and also fixes the position of the fuse plug 10 in the rocker switch 30.
- the monitoring circuit also uses the contact elements 70, 71 of the main circuit on one side and closes the monitoring circuit via further contact elements 50, 52, 53 and a high-resistance resistor 51.
- the contact elements 50 and 52 and the resistor 51 are in an interior 32 of the rocker switch 30 arranged.
- the contact elements 50, 52 and 53 are also spring elements elements so that reliable contacting is ensured.
- a lamp 35 In the interior 32 of the rocker switch 30 there is also an optical control display, a lamp 35, only indicated schematically here. As soon as the main circuit is interrupted, in particular by the fuse link 20 melting, a sufficient current flows through the monitoring circuit so that the control indicator 35 lights up. This indicates a defect in the main circuit.
- the control display 35 is positioned behind a transparent window 33, so that the operator can see the control lamp in the rocker switch 30 made of otherwise non-transparent material.
- the interior 32 of the rocker switch 30, in which, as described above, both the lamp 35 and some devices of the monitoring circuit are arranged, is essentially completely closed, so that damage to the devices is excluded.
- the interior 32 has only two contact openings 56 and 57 in order to enable contact between the contact devices 52 and 53 or 50 and 70.
- the contact between the elements 50 and 70 is always closed as soon as a fuse plug 10 with a fuse insert 20 is inserted into the rocker switch 30.
- the contact between the contact elements 52 and 53 only exists when the rocker switch 30 is in its switched-on position.
- Fig. 2 shows the rocker switch 30 in its off position. It can be seen that both the main circuit and the monitoring circuit are each interrupted twice, namely on the one hand between the contact elements 70 and 71 and between the contact element 72 and the fuse link 20 and on the other hand on the shared contact elements 70 and 71 and on the contact elements 52 and 53rd
- the resilient contact element 53 engages in a recess 80 in the outer wall of the inner region 32 of the rocker switch 30 and is thereby reliably positioned.
- connection between the contact elements 50 and 70 is still present, since the fuse plug 10 together with the fuse link 20 is still in the working position in the rocker switch 30.
- control display 35 is covered to the outside both by the operating handle 31 of the rocker switch 30 and by the housing 2, so that the control display 35 is not visible to the viewer.
- the control display 35 is only visible in the switched-on position of the rocker switch 30 because it is then in a central position within an opening 90 in the housing 2, through which the operating handle of the rocker switch 30 protrudes.
- Handle part 11 of the security plug 10 have through openings 95 and 96 which are offset from one another in an end position of the security plug 10 which is pushed into the rocker switch 30, that is to say not in alignment with one another. These through openings 95, 96 serve to carry out a locking device (not shown).
- the safety plug 10 To carry out the locking device, the safety plug 10 must be pulled out of its end position in the rocker switch 30, so that the through openings 95 and 96 are at least partially aligned. A locking device, which is then pushed through the through openings 95, 96, prevents the securing plug 10 from being pushed back into its end position.
- the rocker switch 30 cannot be pivoted into its switched-on position because Push parts of the fuse plug 10 against parts of the housing 2 and prevent the rocker switch 30 from being turned over to the switch-on position.
- the rocker switch 30 is reliably held in its switch-off position, which is particularly important when machines or electrical devices that are supplied via the switch fuse unit 1 have to be repaired. Switching on or accidentally caused by vibrations, for example, and thus endangering the operator is thus reliably avoided.
