    Method for installing an outlet
    The present invention relates to a method for applying a socket to hard material, in particular stone or composite, wherein the hard material serves as a base, ceiling or wall covering.
    The patent US2003 / 0037952 describes a method for applying a socket in a wall covering, which socket is covered by a cover plate made of hard material, in particular stone. The described cover plate is cut to size from a stone plate and then processed in such a way that it acquires the same shape as a standard cover plate.
    The known method makes use of a cover plate which has the consequence that the socket continues to stand out as an unevenness with respect to the ceiling, floor or wall covering of hard material. This affects the aesthetics of the coating. Homeowners or other users want the sockets to be integrated as much as possible in their ceiling, floor or wall coverings made of hard material.
    The object of the present invention is to realize a method for installing a socket which avoids or minimizes disturbance of the bottom, ceiling or wall covering by a cover plate and thus an integration of a socket with the bottom, ceiling or wall covering.
    To this end, the method according to the invention relates to a piercing of the hard material at a location where the socket can be arranged such that the contact pins of a plug for that socket and, if required, of the socket can pass through, whereafter a first side of said hard material is provided with a blind opening, dimensioned for receiving at least one electrical plug through the bores; then a contact housing part, where the contact terminals of the socket are stored, is placed on a second side of the hard material such that the second side of the hard material makes almost direct contact with that contact housing part, and wherein the contact housing part is placed such that the grounding contact pin and the socket terminals of the socket are opposite the holes.
    The invention thus uses the available hard material to provide the socket therein, thereby avoiding or minimizing a disturbance of the surface of the first side by a mounting cover plate. A plug is then inserted into the blind opening and incorporated into the hard material and the contact holes of the socket can be reached through the holes provided. Because the hard material itself now forms the cover plate and the contact housing part at the level of the blind opening closely fits on the second side, the pressure of the plug on the base of the blind opening is absorbed and distributed over the contact housing part. This has the additional advantage that the thickness between the base surface of the blind opening and the second side of the hard material can hereby remain limited.
    A first preferred embodiment of a method according to the invention is characterized in that the hard material is selected with a minimum density of 400 kg / m3. This has the advantage that the integrity of the hard material is guaranteed.
    A second preferred embodiment of a method according to the invention is characterized in that composite is chosen as the hard material. This also has the advantage that the integrity of the hard material is guaranteed.
    A third preferred embodiment of a method according to the invention is characterized in that the provision of the blind opening and the penetrations in the hard material is carried out by means of a computer-controlled "Computer Numerical Control" (CNC) program in function of the thickness and density. of the hard material. This has the advantage that the provision of the blind opening and the penetrations are carried out quickly and accurately.
    A fourth preferred embodiment of a method according to the invention is characterized in that after drilling through the finishing of the first side and of the blind opening in the hard material is carried out by means of a series of sanding steps. After performing a series of sanding steps, the surface of the hard material changes from a rough surface to a finished surface. This has the advantage that both the blind opening and the first side are finished in the same way.
    A fifth preferred embodiment of a method according to the invention is characterized in that the contact housing part comprises at least two protrusions which are each releasably locked in notches of resilient pin holders arranged on a housing. This has the advantage that the contact housing part is shielded by the housing and can be disassembled from the housing later if required.
    A sixth preferred embodiment of a method according to the invention is characterized in that the housing, together with the contact housing part, is attached to the second side of the hard material by means of at least two first fixing elements. This ensures a precisely fixed connection of the contact housing part at the level of the blind opening on the second side of the hard material.
    A seventh preferred embodiment of a method according to the invention is characterized in that a positioning of first fixing points for the first fixing elements is determined by placing a first caliber on the bores. In the method, the first caliber is first placed on the punctures. Once the first caliber is centered on the bore holes, the first mounting points are determined for the first mounting elements of a housing.
    An eighth preferred embodiment of a method according to the invention is characterized in that first fixing holes are drilled in the second side of the hard material at the position of the first fixing points into which threaded rods are anchored and wherein the housing with the contact housing part on the second side of the hard material material is attached by means of fixing nuts, which are screwed onto the threaded rods. This creates an accurate attachment of the housing to the second side of the hard material.
    A ninth preferred embodiment of a method according to the invention is characterized in that before perforations are made in the hard material, a disc is cut from the hard material and wherein the penetrations and the blind opening are provided on the disc and the contact housing part is attached to the disk is mounted preferably by means of at least two insulated fastening elements. This allows the disc with the contact housing part to be quickly removed from the housing if desired.
    The positioning of second fixing points for the insulated fixing elements is preferably determined by means of a second caliber which is positioned by means of the bores. Once the second caliber is centered on the bore holes, the second fastening points are determined for the isolated fastening elements of a further housing over the contact housing part.
    Preferably, second fastening holes are drilled into the disc at the position of the isolated fastening elements, into which isolated threaded rods are anchored as isolated fastening elements. The contact housing part is then fastened to the disk in a preferred embodiment by means of insulated fastening nuts which are screwed onto the insulated threaded rods. The insulated fastening elements of the contact housing part avoid potential unwanted electrical conductivity.
    A further preferred embodiment of a method according to the invention is characterized in that a clamp is placed in the blind opening of the disc for releasing the disc from the hard material. By subsequently pulling on the clamp with a force perpendicular to the first side and leaving from the first side, the contact housing part is released from the housing. This preferred embodiment has the advantage that the socket can be dismantled quickly.
    The invention will now be described in more detail with reference to an embodiment shown in the drawing.
    Figure 1 shows a floor covering in which a socket obtained by applying a method according to the invention is arranged in the drawing; Figure 2 shows a cross-section through the floor covering at the place where the socket is fitted; Figure 3 shows a rear view of the socket on the floor covering; Figure 4 shows a cross-section through the floor covering at the place where the socket is mounted on a disc which is cut from the floor covering; figure 5 shows a cross-section through a clamp with which the socket in the disk shown in figure 4 can be removed; and figure 6 shows a front view of the clamp shown in figure 5.
    In the drawings, the same reference numeral is assigned to the same or analogous element.
    The floor 2, shown in figure 1, contains a plurality of tiles or plates 4-1, 4-2, ... and for the sake of clarity, a socket is only provided in one tile or plate. The method according to the invention will be described with reference to a stone tile 4-1 in the stone floor 2. This invention is not limited to stone tiles and finds its application in any hard material such as, for example, marble, granite or hard wood, with a minimum density of 400 kg / m3 which serves as a base, ceiling or wall covering. This has the advantage that the integrity of the socket to be manufactured is guaranteed.
    In a further preferred embodiment, composite is chosen as the hard material. This also has the advantage that the integrity of the hard material is guaranteed.
    A power outlet is a device where equipment can be connected to an electrical energy source via a plug. As a practical exemplary embodiment, a grounded socket for a type E mains plug required in the General Regulations for Electrical Installations (AREI) since 1981 in Belgium is used for the description of the invention. This type E plug is completely round and has an earthing contact pin that protrudes. Because of this pin, a plug only fits into the socket in one way. A contact housing part 9 of the socket comprises contact terminals 14, 15 and an earthing contact pin 13 to which the electrical lines are attached.
    The tile 4-1, shown in Figure 2, has a first side 8-a, which forms the visible side of the tile in the floor and a second side 8-b, which forms the rear side of the tile. Before installing the socket, the desired or chosen location of the socket is first determined.
    First, three bores 5, 6 and 7 are drilled into the hard material 2 at places through which grounding contact pin 13 of a socket to be fitted and / or the contact pins of the plug have to pass. A first caliber is preferably used to ensure the correct positioning of the bores 5, 6 and 7 relative to each other. The drilling of the three holes 5, 6 and 7 can also be carried out by means of a computer-controlled CNC program.
    Afterwards, a blind opening 3 is provided at the level of the bores 5, 6 and 7, which opening is dimensioned for receiving at least one electrical plug. For example, the provision of the blind opening 3 in the hard material 2 is carried out by means of milling with a computer-controlled CNC program which is adjusted in function of the thickness and density of the hard material 2. This has the advantage that the application of the blind opening 3 and the holes 5, 6 and 7 can be made quickly and accurately. However, it is also possible to use a mold for this. Due to the presence of the blind opening, the plug can then penetrate into this blind opening and its contact pins can pass through the bores 6 and 7.
    The remaining thickness between the base surface 18 of the blind opening 3 and the second side 8-b of the hard material 2 is between 1 mm and 2.5 mm, in particular 2 mm, depending on the density of the hard material 2.
    The finishing of the blind aperture 3 and the bores 5, 6 and 7 are carried out by means of a series of finishing steps to transition from a rough surface to a finished surface. Polishing is preferably done in eight steps. Sanding is first with a coarse grain size 36, then with grain size 60, then with grain size 120, then with grain size 220, then with grain size 320, then with grain size 500, then with grain size 1000 and finally with grain size 2000.
    Subsequently, first fastening holes 16 are drilled at first fastening points in the second side 8-b of the hard material 2. In a preferred embodiment, a first caliber with positions for fastening holes 16 is placed on the bores 5, 6 and 7. Once the first caliber is centered on the bores 5, 6 and 7, the positioning of the first fixing points for the first fixing elements 10,12 of a housing 11 is unambiguously determined.
    The first mounting holes 16 are preferably drilled with a secured depth limiter. After drilling, a preferably insulated threaded rod 10 is placed in each first fixing hole 16, which hole is then filled with, for example, a thermosetting plastic, in particular an epoxy resin, in order to secure the threaded rod 10 in the fixing hole 16.
    A contact housing part 9 comprises at least two protrusions 20 arranged on its longitudinal sides. A housing 11 comprises at least two resilient pin holders 21 provided with notches. When mounting the contact housing part 9 in the housing 11, each protrusion 20 is each releasably locked in the notches of the resilient pin holders 21.
    The housing 11 is placed together with the releasably locked contact housing part 9 of the socket on a second side 8-b of the hard material 2 such that the second side 8-b of the hard material 2 makes almost direct contact with that contact housing part 9, and wherein bore 6 gives access to the contact terminal 14, bore 7 gives access to the contact terminal 15 and the grounding contact pin 13 penetrates through bore 5. For this purpose, the housing 11 in which the contact housing part 9 is received is slid over the threaded rods 10 through first fixing openings 17 until the housing 11 touches the second side 8-b.
    The presence of the housing 11 on the second side 8-b has the advantage that the contact housing part 9 is shielded by the housing 11. Because the contact housing part 9 in the housing 11 is detachably mounted, the contact housing part 9b can later be disassembled from the housing 11 if necessary.
    Afterwards, the housing 11 together with the contact housing part 9 is fixed on the second side 8-b of the hard material 2 by means of fixing nuts 12, which are screwed onto the threaded rods 10. The contact housing part 9 is mounted on the housing 11 by its protrusions 20 which are locked in the notches of the resilient pin holders 21 and is pressed against the second side 8-b by the housing 11 screwed to the second side 8-b. always kept in its fixed position. Because the contact housing part 9 closely adjoins the second side 8-b at the level of the blind opening 3, the pressure of the plug on the base surface 18 of the blind opening 3 is absorbed and distributed over the contact housing part 9.
    Alternatively, the mounting of the housing 11 can be realized by using screws and plugs or other fastening elements.
    The invention therefore no longer uses a separate cover plate and uses the hard material 2 to integrate the socket therein. A disturbance of the surface of the first side 8-a by a cover plate is avoided or is minimized in that the hard material 2 now forms the cover plate itself.
    Figure 3 shows in a preferred embodiment a second side 8-b of the hard material 2 on which the housing 11 is mounted against the second side 8-b by means of four fixing bolts 12 which are screwed onto the threaded rods 10.
    According to the invention, a standard surface-mounted housing is preferably used as housing 11. However, the height of a standard surface-mounted housing must be adjusted to the extent that the outer surface of the contact housing part 9 that provides access to the contact terminals 14, 15 can make almost direct contact with the second side 8-b after mounting in the housing 11 of the hard material 2.
    In another embodiment, for example, in case the hard material 2 is not sufficiently thick, an additional reinforcement, such as in particular a fiberglass mat with epoxy resin or an aluminum plate, can be attached to the second side 8-b of the hard material 2 at the level of the socket. Of course, such reinforcement must be provided with penetrations for the contact pins.
    In yet another embodiment, the housing 11 can be glued, magnetically attached or secured with a snap system.
    Figure 4 shows a further preferred embodiment and differs from Figure 2 in that, before perforations are made in the hard material 2, a disc 19 is cut from the hard material 2. The holes 5, 6 and 7 and the blind opening 3 are then provided on the disc 19 and the contact housing part 9 is fixed on the disc 19.
    However, in this embodiment, shown in Figure 4, the coherence between the disk 19 and the hard material 2 is broken. In order to prevent the disc 19 from becoming loose in the hard material 2 and from the contact housing part 9, it is necessary to provide an additional attachment between the disc 19 and the contact housing part 9. This additional attachment is preferably provided in an analogous manner to the already described attachment of the housing 11 on the second side 8-b of the hard material 2.
    Preferably a second caliber is placed on the bores 5, 6 and 7 mounted on the disc 19. Once the second caliber is centered on the bores 5, 6 and 7, the position of the second fixing points for the insulated fixing elements 23, 24 is of the contact housing part 9. The second mounting holes 22 are preferably drilled with a secured depth limiter. After drilling, an insulated threaded rod 23 is preferably placed in each fixing hole 22, which hole is then filled there with, for example, a thermosetting plastic, in particular an epoxy resin, in order to secure the threaded rod 23 in the fixing hole 22.
    Preferably, the contact housing part 9 is provided with at least two first mounting slots 25 to receive the insulated wire rods 23. The contact housing part 9 is then slid over the insulated wire rods 23 against the disc 19 via the first mounting slots 25.
    Afterwards, the contact housing part 9 is screwed onto the disk 19 by means of insulated, preferably plastic, fixing nuts 24. Alternatively, the mounting of the contact housing part 9 against the disk 19 can be realized by using insulated screws and insulated plugs or other insulated fastening elements.
    As a second alternative to the attachment of the contact housing part 9, use can be made of an insulated U-bracket provided with at least two protrusions on either side of the longitudinal sides of the contact housing part 9. Each protrusion is each provided for receiving the insulated wire rods 23. The insulated U-bracket is mounted against the rear side of the contact housing part 9. Finally, the contact housing part 9 is screwed onto the disk 19 by means of also insulated, preferably plastic, fixing nuts 24.
    In the case of renovation or repair, it may be necessary for a technician that the contact housing part 9 be removed again. The contact housing part 9 can be removed from the lock 20, 21 of the housing 11 by means of preferably a clamp 26 as shown in figures 5 and 6. The clamp 26 is preferably made of plastic, such as in particular Polyoxymethylene (POM) . The clamp 26 is preferably hollow and contains a first end which is dimensioned to fit tightly into the blind opening 3. The first end contains a number of segments which can expand radially evenly. The first end also includes a clamping slot 30 for receiving the grounding contact pin 13 in the blind opening 3. A second end includes a handle 29.
    Preferably, a clamp 26 is used in combination with a conical rod 28, as shown in Figures 5 and 6. The conical rod 28 is dimensioned such that when the conical rod 28 is penetrated into the hollow space of the clamp 26, the segments of the first end of the clamp 26 extends radially evenly.
    First, the clamp 26 is placed in the blind aperture 3 of the disc 19, the grounding contact pin 13 in the blind aperture 3 of the disc 19 being received by the clamp slot 30. By subsequently rotating the conical rod 28 preferably one full revolution in a clockwise direction the clamp 26 in the blind opening 3 extends radially such that the clamp 26 is clamped in the blind opening 3. Finally, by preferably pulling a handle 29 of the clamp 26 with a transverse force perpendicular to the first side 8-a, the disc 19, together with the contact housing part 9 screwed to it, is released from the housing 11.
    The contact housing part 9 with the electrical connections is then accessible again for, for example, an intervention by a technician. After the intervention, the contact housing part 9 screwed onto the disc 19 can easily be mounted back in the housing 11 thanks to the described resilient locking 20,21 between the two parts 9,11.
