ELECTRICAL PLUG DESCRIPTION OBJECT OF THE INVENTION

The present invention relates to an electric plug that can fully cover the perimeter of any room to enable the connection of receivers without the need for multiple plug base extensions.

BACKGROUND OF THE INVENTION

Electrical plugs are known, which comprise a base that can be fixed in a construction element, such as a wall, and a plug-in plug that is arranged in some cables of the receivers to be connected to the network.

The current configuration of the bases includes their arrangement on the walls, usually a single or multiple on each wall, so that many times the furniture or simply an insufficient length of the receiver cables prevents a comfortable and / or operational connection, forcing resort to extensions with single or multiple plug bases that generate the existence of wiring on the ground, with the consequent danger of tripping, dirt accumulation and an inefficient aesthetic.

Another additional disadvantage of the traditional plug bases is that you have to cut cables, splice and / or pick up a set of cables for each plug base, making mounting more expensive, and also in embedded distributions the corresponding auxiliary works are necessary to perform and cover the rubbing where the pipes are placed, in which later the cables must be inserted and spliced to the mechanisms

DESCRIPTION OF THE INVENTION

The electrical plug of the invention has a configuration that solves the problems

raised. It is of the type comprising a base and, at least, a plug-in plug to said base.

-at least, a modular rail comprising support and / or fixing means to a construction element, such as a wall, floor, ceiling, corners between these elements as a baseboard, etc,

-a grooves of electrical sockets, which in any case comprise grooves with polar sockets (phase and neutral in single-phase installations) and optionally, at least, one groove of grounding arranged along said rail, formally and dimensionally suitable for receiving and retaining, with the possibility of extraction, the conductive males of a plug, and which comprise internal conductors of suitable section and shape to come into contact with the males inserted in the grooves to transport current in sufficient magnitude thereto, and

-a electrical connections of the inner conductors to the corresponding external conductors of electric power supply.

In this way the realization of laborious installations and connections is avoided, since it is only about splicing the different modular rail modules together, with the only care to adjust it to the length of the wall or the perimeter of the room, or needs of the space to install. Once the entire desired length is installed, a single connection is made per stay with the electrical installation, or the end of the base is plugged into a conventional plug, avoiding the traditional, unsightly and laborious conventional installations, being able to plug in any point of the Modular rails - and therefore at the most convenient point of the room - any plug of a receiver.

-a electrical connections (8) (see figs 14 and 15) of the inner conductors (7a, 7b) to the corresponding external conductors (9) of electric power supply.

The modular rail (2) is materialized in extrusion parts, and ideally in extrusion of electrically insulating materials, such as insulating plastics.

In this preferred example (see fig. 5), the modular rail (2) comprises a support (2a) configured by a profile in general form of C (it can be any other) comprising a recess (20) with its entrance (21) narrowed, arranged in its central branch (2aa); and a core (2b) in a complementary manner to said recess (20) to be inserted with retention therein. Likewise, the means for supporting and / or fixing to a construction element (3) will comprise plates (14) with holes (15) for securing said construction element (3) and provided with lateral wings (16) for retaining eyelashes. ends (2ab) of the lateral branches (2ac) of the support (2a), while in the support (2a) and / or in the core (2b) there are configured longitudinal conductor conductor channels (2bb), in which they are inserted and retained the inner conductors (7a, 7b). For example, in figures 1, 2, 3, 5, 6 and 7, the conductor-carrying channels show a configuration with channels (2bb) for two active conductors (7a) (phase and neutral) arranged in the core, while the Figures 18 and 19 show another configuration for three active conductors (7a) (three phases for example), two of them arranged in the support (2a) and another in the core (2b)

Monoblock configuration extruded in the support (2a) or be added parts, as seen in the second view of Figure 2.

For installations with a grounding conductor, an electrical groove (4b) is also provided, which carries the grounding conductor (7b) (see figs 1, 2, 5, 6, 7 and 8) in the corresponding channel ( 2bb) driver carrier (see fig 5), while the provision of a grounding adapter (5) attachable to the corresponding plug (101), for example a shuko plug, is also provided, as shown in figures 1 and 2, and comprising fixing elements (5a) to said pin (101), contact elements (5b) with the ground (101a) of said pin (101) and, at least, one shoulder (5c) insertable in the electric ground groove (4b) so that it makes contact with the ground conductor (7b).

In the base (2) standardized plugs can be inserted, such as Shuko plugs (see fig. 1 to 3) as already mentioned, simply by arranging the slots (4a) and active conductors (7a) at the convenient distance, although the The invention has also provided for the implementation of specific pins (101) such as the one shown in Figure 3, which comprises two flat male (105) provided with flexible slats (105a) projected towards the active conductors (7 a) of the base (100), increasing the contact surface with them. With the same philosophy, another variant of the invention shown in Figure 4 has provided that the core (2b) comprises a single polar groove (4a) in which two active conductors (7a) are arranged facing each other, while the plug ( 101) comprise an insulating male (105) provided with opposite flexible slats (105a) projected towards said active conductors (7a).

The invention additionally comprises (see figs. 7 to 14) auxiliary parts (10, 11, 12, 13) for the base (100), which comprise splice parts (10, 11) provided with fastening means (which in this case are the contact extensions (24)) to the ends of two modular rails (2) and electric bridges (23) with contact extensions (24) with the conductors (7a, 7b) of said modular rails (2), insertable in the two ends of both modular rails (2) to be spliced.
