Definitions
- the present invention relates to an electric meter comprising a removable cover positionable in two positions on the meter.
- Electrical meters are already known from the prior art, comprising a housing delimiting a terminal block arranged to allow the connection of electric cables to the meter.
- the meter includes a cover covering the terminal block to prevent access to the various electrical connections of the meter.
- a cover generally comprises, on its internal face, a wiring diagram allowing a user, during an intervention on the meter, to make or check if the electrical connections correspond to the diagram.
- the object of the invention is therefore to provide a simple solution for maintaining the cache of an electric meter in the closed position but also in the open position to facilitate the completion of connections.
- the subject of the invention is an electrical meter comprising a housing delimiting a terminal block of connection to cables and a removable cover at least partially covering the terminal block.
- the counter includes a fixing means arranged to maintain said cover on a front face of the housing by discovering the terminal block and leaving an apparent internal face of the cover for a user located opposite the front face of the housing.
- Fixing the cover in the vicinity of the electrical connection area in question thus makes it easy to access information specific to mounting and wiring the meter ⁇ without the cover being placed on the ground, held manually or the latter is lost. during a user intervention.
- the fastening means of the device is a quarter-turn screw, captive of the cover, comprising an anchor body surmounted by a head, the body being arranged to hold the cover on the housing by covering the terminal block and the housing having a housing for receiving the head and hold the cover on the housing by discovering the terminal block.
- the quarter turn screw thus provides a dual function since it allows the cache to be fixed in two distinct positions. This is an ideal solution since no additional parts are required and, on the other hand, quarter-turn life can be made captive. Of course, this principle can also use a dedicated room.
- the screw is mounted axially movable between a first position in which the head is embedded in the cover to allow the fixing of the cover on the housing over the terminal block and a second position in which the head is projecting from the cover to allow inserting the head into the housing housing.
- the means of attachment of the device is an abutment disposed on the housing to retain the cover when it discovers the terminal block.
- the stop is positioned so that the cover is deformed when the cover is in abutment and in position on the housing to leave the terminal board uncovered.
- FIG. 1 is a front view of a first embodiment according to the invention, the cover being in the closed position;
- FIG. 2 is a front view of the first embodiment according to the invention, the cover being in the open position;
- FIG. 3 is a perspective view of a quarter-turn screw used in the first embodiment
- FIG. 4 is a front view of a second embodiment according to the invention, the cover being in the closed position;
- FIG. 5 is a front view of the second embodiment according to the invention, the cover being in the open position.
- the electric meter 1 comprises a housing 2 in which are housed various electrotechnical elements serving to measure a amount of energy consumed, a cache 3 closing a terminal block, a dial 4 information display reflecting energy consumption and various buttons for controlling the various functions of the electric meter.
- FIG. 3 shows the screw 6 which comprises a head 12, a body 13 and two projections 14 extending perpendicularly to the axis of the body of the screw 6 at the free end of the body 13.
- the housing 2 delimits an orifice 11 arranged in the housing 2 so that when the screw 6 is engaged in the orifice 11 and undergoes a quarter turn in the orifice, the cover 3 is then fixed to the housing according to a closed position covering the terminal block.
- the housing 2 further defines a housing 7, directly derived from molding, adapted to receive and hold the screw head 6 as illustrated in Figure 2 which illustrates the same electric meter 1 as that of Figure 1 in an open position cache thus maintained on the housing 2 so as to discover the housing 2 while leaving an apparent internal face of the cache.
- the screw head 6 is for this purpose forced into the housing 7 now holding the cover 3 in the open position.
- Such a configuration thus allows a user to access information 8 specific to the assembly and wiring printed, etched or glued on the internal face of the cover 3.
- the cover 3 thus fixed discovers the terminal block and allows access to the various cable connections 10 of the meter.
- the screw 6 is mounted on the cover 3 with an axial clearance between the screw 6 and the cover 3.
- the screw 6 is thus mounted axially movable between a first position in which the head is embedded in the cover to allow the fixing of the cover on the housing over the terminal block ( Figure 1 ) and a second position in which the head is projecting from the cover to allow the insertion of the head into the housing housing for fixing the cover 3 in the open position ( Figure 2).
- Fixing the cover 3 in the closed position and in the open position is thus achieved by using each side of the screw 6 according to the following configuration.
- FIG. 4 illustrates a second embodiment according to the invention in which the cover 3 closing the electrical connections of the counter also covers the counter 17 by defining a frontage.
- the cover 3 has a rectangular opening 19 provided for this purpose so that the cover surrounds the dial when the cover 3 is in the closed position as shown in Figure 4.
- the counter has a shoulder zone 22 surrounding the dial and having a thickness equal to the thickness of the cover 3.
- the cover 3 is then fixed to a support zone 23 extending immediately after the shoulder 22 over the entire periphery of the counter 17 using a simple screw 16 passing through the cover 3.
- the cover 3 is here in the closed position.
- the cover 3 can also be attached to the counter 17 by clipping.
- Figure 5 shows the cover 3 in the open position according to the second embodiment.
- the upper part of the support zone 23 of the counter 17 comprises a lug 18 or more particularly a stop on which comes to rest one of the edges of the opening 19 of the cover 3 so that the information 8 specific to the mounting and to the wiring arranged on the inner face of the cover are visible to a user and that the electrical connections of the meter are accessible.
- the rectangular-shaped cover 3 arranged vertically in length in the closed position according to FIG. 4, is arranged horizontally in length in the open position.
- the arrangement of the support zone 23 of the counter 17 and the cover 3 in the open position therefore does not allow the opening 19 to completely surround the support zone 23 of the counter 17. Therefore, the fixing of the cover 3 on the stop 18 is made by elastic deformation of the cover 3 at the edge of the opening 19 abutting on the lug 18.
- the mechanical retention of the cover on the housing can be ensured by any means and for example by elastic deformation, clipping, snapping, locking ...
