[0004] DESCRIPTION

[0005] The present invention relates to an electrical multi-socket module , preferably with at least four sockets , and assembly comprising said module inserted into an electrical box .

[0006] The invention is made with particular reference to a four-socket multi-socket module insertable into an electrical box compatible with three single-socket modules , however, other configurations are not excluded .

[0007] PRIOR ART

[0008] In the field of electrical modules , modules , also known as switches , are known to be designed to be inserted into special electrical boxes , the latter being embedded in a wall or applied superficially to them.

[0009] Known modules generally include a single electrical socket configured to receive a corresponding electrical plug . We will refer to said modules as " single modules" for brevity .

[0010] There are various types of sockets , the shape and mechanical requirements of which are governed by codi fied standards, such as those according to international standard IEC 60884-1, or national standards IEC 23-50, TIS-166-2549, GB 1002-2008 and subsequent amendments / additions .

[0011] Popular electrical boxes are capable of housing more than a single module, e.g. 3 of type Pll / 17 standard CEI 23-50 and subsequent amendment s / additions , Pll / 17 for short. Such boxes are, for example, codified by standard CEI 23-74 to standardization sheets A7 and A8.

[0012] What most characterizes said boxes in terms of constraining the arrangement of the modules is the fact that said standard requires that the boxes couple to the electrical modules by means of a pair of screws with a distance between them of 83.5 mm ± 0.5 mm.

[0013] The CEI 23-74 standard also provides that there may be different boxes, called "special boxes." Boxes in use in other countries may also differ according to standards other than CEI 23-74. However, we observe that in each country there are modules similar in size to Pll / 17 and similar boxes to accommodate three modules. Similarity can be found, for example, in the distance between said screws, which is reasonably in the range of 83.5 ± 1mm. We will indicate these boxes according to said CEI standard and similar ones as "three-module" boxes .

[0014] Although the present invention is applicable to any type of box, as will be evident below, the preferred forms of implementation are with respect to said standard three-module boxes.

[0015] If more than three sockets are to be installed in the wall, a larger box must be primarily set up in the wall. This, however, may not be possible, as the wall is pre-existing and equipped with the most common three- module boxes.

[0016] There are also sockets that require bulkier modules than Pll / 17, such as sockets according to the GET 23-50 standardization sheet P30 and / or P40, commonly known as ' SCHUKO multiple receptacle' type sockets or even just 'SCHUKO' sockets, and a three-module box is known to accommodate only one.

[0017] To overcome these drawbacks, modules comprising more than one socket have been created, such as two- socket modules of the P40 or P30 or 'SCHUKO' type, covered by the patent 102020000026936, or the Italian utility model 20202000006007, or mixed-socket modules, covered by the Italian utility model 202019000001252 and the Chinese utility model CN218472482 U.

[0018] All of these multi-socket modules make maximum use of the space available in the three-module box, but they have reached a limit, whereby it is not possible to go beyond 2 'SCHUKO' type sockets or one 'SCHUKO' socket associated with a maximum of 2 Pll sockets.

[0019] Thus, the number, type and arrangement of sockets feasible in a single module are limited to date.

[0020] Moreover, such arrangements actually make it impractical to couple and decouple plugs, which are located very close together. In the case, then, of plugs with outgoing transverse cable, with respect to the direction of insertion into the socket, the additional "crowding of sockets" could bring the problem of geometric interference .

[0021] There is therefore a latent need in the industry to overcome these limitations .

[0022] A general purpose of the present invention is therefore to solve all or part of the problems of the prior art .

[0023] Another purpose of the present invention is to enable the reali zation of multi-socket modules capable o f easily accommodating preferably at least four sockets by overcoming the limitations of inter-associable types of the prior art , where the multi-socket module can be inserted into a three-module box .

[0024] Another purpose of the present invention is to enable the reali zation of multi-socket modules that can easily accommodate at least four sockets by overcoming the limitations of convenience of inserting the relevant plugs .

[0025] Another purpose of the present invention is to provide a multi-socket module comprising at least four sockets that can be inserted into a three-module box without the need to modi fy said boxes , especially i f they are of standard type , to increase the number of sockets .

[0026] Another purpose of the present invention is to provide a multi-socket module comprising at least four P40 or P30 type sockets that can be inserted into a three-module box .

[0027] Another purpose of the present invention is to provide an aesthetically pleasing multi-socket module when applied to a wall . Another purpose of the present invention is to provide a multi-socket module that is easy and inexpensive to implement .

[0028] GENERAL INTRODUCTION

[0029] Technical problems are solved by a multi-socket module and an assembly comprising said module as shown in the attached claims .

[0030] DETAILED DESCRIPTION

[0031] Further characteristics and advantages of the present invention will best result from the following detailed description of its preferred forms o f implementation, made with reference to the attached drawings and given for illustrative and non-limiting purposes . In such drawings : figure 1 shows schematically an assembly according to the present invention comprising a quad module according to the present invention, a box with three single modules , and a wall with a recessed hole to receive them, where these three elements are exploded with each other, the box is of a type known in the market for recessing into a plasterboard wall .

[0032] - figure 2 shows the three elements of figure 1 assembled together and in section, viewed from an observation point outside the wall ;

[0033] - figure 3 shows the three elements in figure 1 assembled together as seen from an observation point inside the wall , where the wall alone is in section;

[0034] - figure 4 di f fers from figure 1 in that the quad module is totally exploded; figure 5 is a front view of an assembly comprising the figure 1 module installed in the figure 1 three-single module box, where the perimeter edge of the cavity of said box has been highlighted in transparency; figure 6 is a back view of the figure 5 assembly;

[0035] - figure 7 is like number 5 where the front plate has been removed to see the electrical connector ass e mb lies ;

[0038] - figure 10 shows a quad module ground contact of the previous figures ;

[0039] - figure 11 is like figure 10 in side view;

[0040] - figure 12 shows a ground electrode assembly and a phase and neutral electrode assembly of the quadruple module of the previous figures ; figure 13 shows the wiring location of the cables in the back area of the quad module of the previous figures ; figures 14 and 15 are like 5 and 4 , respectively, where a single three-module box known in the market for recessed installation in masonry walls is shown; - figures 16 to 19 are like 5 and show variants of quad modules that di f fer from that of the previous figures for the types of sockets ;

[0041] - figure 20 is a section, like figure 2 , where an assembly variant is shown with a three-module box for surface wall application .

[0042] Shown with reference to the figures is an electrical socket assembly shown as a whole with reference number 1 , configured to be partially housed in a cavity 2 formed in the wall of a building 4 .

[0043] With reference to the direction of installation in wall 4 , in the following we will , by convention, indicate by front-back direction, or installation direction Z , that which is orthogonal to the outer surface of wall 4 , and by cross directions all those orthogonal to the installation direction Z . Accordingly, with reference to an installed configuration, the front side of assembly 1 is that facing the outside of wall 4 , the back side is that facing the inside of wall 4 , and the side sides are those facing in the transverse directions .

[0044] Assembly 1 preferably includes a transverse direction of length X and a transverse direction of width Y, where said assembly extends most along the former .

[0045] Assembly 1 comprises :

[0046] - an electrical box 5 . a multi-socket module 10 partially inserted into a cavity 7 of said electrical box 5 . A multi-socket module 10 comprises at least four sockets 20 , the one shown in the figure contains exactly four sockets and is therefore also simply called a "quad module."

[0047] The electrical box 5 is preferably of the three- module type. As mentioned earlier three-module box 5 means an electrical box according to CEI 23-74 standardization sheets A7 and A8, and similar. Similar means at least all boxes of even different or special shape, capable of receiving three single-socket modules of type Pll / 17 (not shown) , and / or all boxes to which the multi-socket module is fixable by at least one pair of screws directed in the front Z direction with a distance between them of 83.5 mm ± 1mm.

[0048] According to the preferred examples, modules and boxes according to the present invention are fastened to each other with at least one pair of 6 fastening screws, with spacing D between them of 83.5 ± 0.5 mm and axis parallel to the frontal direction Z. The holes or screws can indifferently be on the box or module.

[0049] The box 5 comprises a cavity 7 for housing the module 10 which has a front access opening 3.

[0050] The multi-socket module 10 includes a front interface plate 12 protruding from said box 5 in the transverse direction, wherein at least four groups 15 of alveoli 16, each corresponding to an electrical socket 20, are formed on said plate 12.

[0051] Each assembly is contained in a portion 30 of the front interface plate 12, at least equal in extent and transverse shape to the transverse size area of a cavity 32 of a standard IEC 25-50 P40 socket, where each of said portions partially overhangs the perimeter edge of said cavity 7 of said box in the transverse direction. More preferably it overhangs the entire box. Portions 30 are separated from each other, i.e., they do not overlap. Said portions 30 have a planar front surface, so as to provide a back stop to a relative plug inserted into the socket. This means that the sockets are planar at least for a cross-sectional extension corresponding to portions 30. Advantageously, such a portion is compatible with various types of plugs, e.g., plugs, including Schuko plugs or those defined by the international electrotechnical commission (IEC) as plugs of types A, B, C, E, F, L, 0 and their possible combinations.

[0052] In the examples shown in figures 1 to 15, all the sockets 20 are of the P40 type standard IEC 25-50, so that said portion 30 coincides with the bottom 31 of cavity 32 of each socket 20 configured to receive a related plug. This means that in the case of four P40 sockets, all relative cavities 32 extend transversely beyond cavity 7 of box 5, as clearly schematized in figure 5 and the variant in figure 14.

[0053] An equivalent situation is obtained by referring to P30 sockets.

[0054] Figure 3 also makes this concept immediately obvious, since it shows the back 31R of cavity bottom 32 partially projecting transversely beyond box 5.

[0055] In the case of sockets without cavities 32, the portion 30 may be an area of a planar front surface of plate 12, configured to act as a setback to a relative plug .

[0056] In general , the alveoli of each socket 20 , are aligned along an ideal line L, or , in the case of a USB port substituted for a socket, that line is the longitudinal centerline along which the port opening extends ( see the example in figure 18 where the USB port is indicated as 120 ) . The L lines are parallel to each other and are lines of symmetry of the relative portions 30 . Also, preferably, the L lines are closer in the transverse direction to the longitudinal edge of the cavity 7 of box 5 than to its center .

[0057] The sockets preferably are arranged along two lines L parallel to each other and to the longitudinal direction X of box 5 and box body 50 , along which the alveoli 16 are aligned .

[0058] In cases of four sockets , as in the figures shown they are arranged to form the vertices of a quadrilateral , preferably a square .

[0059] Figures 1 to 13 show the main form of implementation in which the sockets are all P40 ; however , alternatives and various forms of implementation are possible and will be described later, where equal or similar elements will be indicated by the same reference numbers , or by the same numbers incremented by 100 or multiples thereof .

[0060] Concerning that point we start by noting that the alveoli can be of any type , so there can be phase , neutral and possibly ground alveoli , that is , configured to receive a connection to the phase , neutral and possibly ground contacts of a related male plug . Figures 1 to 18 show alveoli 16 of P40 or Pll / 17 sockets standard CEI 23-50, while figure 19 shows a variant of alveoli 116 of sockets known as Euro-American hybrids normalized in several standards, including the Chinese standard GB1002- 2008 and the Thai standard TIS 166-2549 and in use for example in Egypt, in Peru, Paraguay, Bolivia, Thailand, Cambodia, Laos, Vietnam, and other countries where the male plugs in commerce are a combination of IEC types F, C, A, and 0 collectively denoted by the number 520.

[0061] In general, there are implementation forms in which the sockets are all the same, such as those in figure 5 or 14 with sockets all P40, or those in figure 16 with sockets all Pll / 17, whose alveoli are contained in respective portions 30.

[0062] However, there are also mixed forms of implementation, such as those in figures 17 and 18 where plugs are mixed.

[0063] For example, an implementation form with at least one P40 socket and at least one of other type, e.g., Pll / 17, is shown in figure 17. Specifically shown is the example of 1 P40 socket (indicated by cavity 32) and three Pll / 17s (indicated by the number 220 and for which dashed area 30 is highlighted) . Another preferred example, not shown, is three P40 sockets and one Pll / 17 or two P40 sockets and at least one Pll / 17 socket.

[0064] Figure 18, on the other hand, shows an example that introduces the general concept that at least one of the sockets is replaced by a USB port, or a group of USB ports, for example, of different sizes and / or types from each other. Various forms of boxes are also provided, e . g . , in the implementation forms in f igures 1 to 13 , three- module boxes 5 of the type commonly known for recessing in plasterboard walls are shown . Three-module 105 boxes of the type commonly known for recessing in masonry walls are shown in figures 14 to 19 .

[0065] Compatibilities with boxes for installation on the wall surface are also provided, an example of which is shown in figure 20 .

[0066] For clarity we note that the assembly according to the form of implementation in f igures 1 to 13 is shown as a whole with the reference number 1 and its module with 10 .

[0067] The assembly according to the form of implementation in figures 14 and 15 is indicated as a whole with 101 and its module with 110 .

[0068] The assembly according to the form of implementation in figure 16 is indicated as a whole with 201 and its module with 210 .

[0069] The assembly according to the form of implementation in figure 17 is indicated as a whole with 301 and its module with 310 .

[0070] The assembly according to the form of implementation in figure 18 is indicated as a whole with 401 and its module with 410 .

[0071] The assembly according to the form of implementation in figure 19 is indicated as a whole with 501 and its module with 510 .

[0072] The assembly according to the form of implementation in figure 20 is indicated as a whole with 601 and its module with 610.

[0073] It is noted that in the context of the present invention, where reference is made to the IEC 25-50 standard and IEC 60670-1 and IEC 23-74, the expert in the field will understand that any updates, variants, modifications are also included.

[0074] With reference to the exploded view in figure 4, module 10 comprises:

[0075] - a box body 50 below the front plate 12, e.g., divided into a perimeter portion, delimited by at least one wall 51, and a bottom 52;

[0076] - a socket protection device 55 for each socket 20, configured to obstruct or clear the passage through the alveoli 16;

[0077] - a group of phase and neutral metal contacts 60, comprising alveoli 17 (figure 12) aligned with alveoli 16 of the front plate; this group is contained in box body 50; a group of ground metal contacts 70, such group, is partially contained in box body 50.

[0078] Box body 50 has at least one opening 53 on the front side, closed by front plate 12.

[0079] The box body 50 shown in the drawings has a plurality of perimeter walls 51 arranged to form an elongated quadrilateral in the transverse direction of length X. The set of walls is also called a portion of perimeter walls.

[0080] The box body, moreover, is internally shaped with partitions capable of housing and supporting contact assemblies 60 and 70. The ground contact assembly 70 includes a ground contact 71 for each socket, connected to each other by a bridge 72.

[0081] Ground contact 70 is best seen in figures 10 and 11.

[0082] It comprises two wings 75 and 76, configured for lateral contact to a schuko-type male plug, facing each other with respect to a plane P parallel to the frontal direction Z and the transverse direction of length X, with respect to which they are asymmetrical.

[0083] Specifically, each wing includes a horizontal center section 77, 78, i.e., parallel to the transverse direction of width Y, interposed between a free apical section 79, 80, and a joining section to the other wing 81, 82, where the apical section 79, 80 is substantially projecting from the horizontal center section 77, 78 in the frontal direction Z.

[0084] The asymmetry is due to the different distance from the front plate 12 in the frontal Z direction at which the central horizontal sections 77, 78 of the two wings are located.

[0085] As a result, with reference to the frontal direction Z, one of the two wings 76, particularly the one with the horizontal center section 78 closest to the frontal plate 12, also has an apical section 79 shorter than the other 75.

[0086] Such geometry is useful to allow said wing 76 with the closest horizontal center section 78 to pass over box 5, particularly the perimeter of cavity 7, by projecting transversely from it. The geometry is also useful in allowing the socket protector 55 to be positioned between the front plate 12 and the hori zontal center section 77 of the other wing 75 which is further from said plate than the section 78 .

[0087] In particular, it will be noted that the protective device 55 extends transversely only in correspondences of that wing 75 and not the other with the nearest section 78 .

[0088] In the illustrated example , which is not limiting, each protective device 55 includes a movable protective shield 91 sliding in the transverse direction of width Y between a blocking position of phase and neutral alveoli 16 and a position of unblocking .

[0089] The protective screen 91 is kept normally closed, i . e . , in the obstructed position, by means of elastic booster means that push it transversely toward the outside of box 5 . Movement toward the unblocked position is conversely toward the inside of box 5 .

[0090] Advantageously, therefore , the geometries illustrated represent an example of the general concept of shaping one of the two wings 76 to pass over the box 5 and the other to create a housing 90 for a protective device , such as device 55 , between it and the front plate 12 . Certainly, wing shapes other than those illustrated that accomplish the same obj ective are all covered by the invention .

[0091] These arrangements are clearly visible in figure 3 and figures 5 to 9 .

[0092] Wings 75 and 76 cross cavity 32 and form the side ground contacts of the P40 socket .

[0093] The contacts 71 also include a central cavity 85 , for example , made by a pair of wings 86 and 87 , which makes the central ground contact of the P40 socket .

[0094] For the sake of completeness , although this is not limiting, we note that the illustrated example shows in figure 13 the wiring terminals 95 for feeding through power cables into module 10 .

[0095] They are preferably arranged on the back side of module 10 and also preferably enclosed in the same box body 50 in order to minimi ze the footprint and simpli fy wiring and installation even on shallower boxes in the Z- direction .

[0096] Figure 15 shows in exploded view the form of implementation according to module 110 . The latter di f fers from the module 10 j ust described mainly in the shape of the box 105 , and the consequent di f ferent arrangement of the attachments of module 110 to it to fit that shape .

[0097] We observe in general that so far we ahve been referring to electrical box 5 , 105 , 605 , to define the partially transversely proj ecting position of the sockets cavities 32 or portions 30 , however given the substantial complementarity between box 5 and box body 50 , it is also possible to refer for this characteristic to modules 10 , 110 , 210 , 310 , 410 , 510 , 610 only, indicating that the cavities 32 or portions 30 are partially transversely proj ecting with respect to box body 50 .

[0098] We note that the invention can also be implemented by considering P30 sockets or their areas where P40 sockets or their transverse overall dimensions

[0099] 30 are indicated.
