Description

Field of technology

The utility model refers to a movable electrical outlet that will find application for powering electrical consumers with a capacity of up to 3.5 kilowatts from a standard lighting electrical installation.

BACKGROUND OF THE INVENTION

A fixed electrical socket is known to supply electrical consumers from the central electrical installation of a building. The socket is usually mounted to the walls of the premises and is intended for plug connection to the consumer. The power cord of the electrical consumer is connected directly to the socket by means of a plug.

In the case of a greater distance of the consumer from the electrical socket, an extension cord may be used, which is a cable with a plug at one end for connection to the electrical socket and a contact module at the other end for plugging in the consumer. The standard contact module of the extension consists of a cup-shaped body and a contact section made of insulating material. The contact section is housed in a cup-shaped body and has two through holes in which contact metal plates are arranged for contact with the pins of the consumer's plug. At the bottom of the cup-shaped body there is a central opening for the cable of the extension, and around the opening there is an annular flange protruding outwards, covering the cable. Extension cords are limited in length.

In the home it is often necessary to use electrical appliances in places where there is only a standard lighting electrical installation. Such places are, for example, basements or attics of existing buildings, yards, outbuildings or newly constructed buildings in which the central electrical installation has not yet been fully installed. To supply electricity to lighting fixtures, such as light bulbs, sockets connected to the lighting electrical installation are installed in suitable places.

Technical essence of the utility model

The purpose of the utility model is to create a movable electrical outlet that can be connected to an existing lighting installation and to provide safe power supply to electrical consumers with a capacity of up to 3.5 10 kilowatts.

The set goal is achieved with a movable electrical contact, including a cup-shaped body and a contact section placed therein, having two passage openings in which 15 contact metal plates are located. At the bottom of the cup-shaped body there is a central hole around which an annular flange is formed.

According to the utility model, the cup-shaped body 20 is fixedly connected to a standard screw base (Edison type) provided at its free end with a metal contact element separated from the screw base by an insulator. The annular flange of the cup-shaped body is placed in 25 holes of the screw base. To make contact with the lighting electrical installation, the metal contact element of the socket is connected to the contact metal plates of one through hole of the contact section by means of a first flexible conductor passing through the central opening, and the wall of the screw socket is connected to the contact metal plates of the second. a through hole by means of a second flexible conductor passing through an opening located in the bottom of the cup-shaped body outside the annular flange. To insulate the screw base from the cup body, the connected end of the screw base is covered by an insulating sleeve resting on the bottom 40 of the cup body.

Preferably, the first flexible conductor and the second flexible conductor are connected to the metal contact element and to the metal wall of the screw socket, respectively, by soldering. 45 The movable electrical socket is connected to the lighting electrical installation by screwing its socket into the available socket for a light bulb.

Various electrical appliances can be connected to the movable contact, such as 3

1968 UI drill, drill, screwdriver, paint gun, etc. similar with a power of up to 3.5 kilowatts.

The main advantage of the movable electrical contact, according to the utility model, is that 5 provides the possibility to supply electrical consumers from an existing lighting electrical installation.

Another advantage is its compact configuration and easy construction. 10

Explanation of the attached figures

The utility model is described in more detail with reference to the accompanying figures, which illustrate one of its exemplary embodiments with the aid of two figures, of which:

Figure 1 is a side view of a movable electrical contact according to the utility model;

Figure 2 is a section along AA of 20; 1.

Examples of implementation of the utility model

As can be seen from Figures 1 and 2, the movable electrical contact consists of a standard contact module fixed to a screw base 10 (Edison type). The contact module includes a cup-shaped body 1 made of insulating material, and a contact section 6, also made of insulating material, housed therein.

As shown in FIG. 2, in the illustrated example, the contact section 6 is mounted at a distance from the upper edge of the cup-shaped body 1 so that a receiving bed for the plug of an electrical consumer is formed. The contact section 6 has two through holes 7 and 7a, in which contact metal plates 8 are arranged for making contact with the pins of the plug of an electrical consumer. In the bottom 2 of the cup-shaped body 1 there is a central opening 3, around which an annular flange 4 is formed.

According to the utility model, the cup body 1 is fixedly connected to a standard screw base 10 (Edison type), provided at its free end with a metal contact element 11, separated from the screw base 10 by an insulator 12. The annular flange 4 of the cup body 1 is placed in the opening of the screw socket 10. To make contact with the lighting electrical installation, the metal contact element 11 of the screw socket 10 is connected to the contacts metal plates 8 of one through hole 7 by a first flexible conductor 9 passing through the central opening 3. The wall of the screw socket 10 is connected to the contact metal plates 8 of the second through hole 7a by a second flexible conductor 9a passing through an opening 5 located in the bottom 2 of the cup body 1 outside the annular flange 4. To insulate the screw socket from the cup body 1 the connected end of the screw socket 10 is covered by an insulating sleeve 13 resting on the bottom 2.

In this example, the first flexible conductor 9 and the second flexible conductor 9a are connected, respectively, to the metal contact element 11 and the metal wall of the screw socket 10 by soldering.

The connection of the first flexible conductor 9 and the second flexible conductor 9a to the contact plates 8 of the openings 7 and 7a of the contact section 6, respectively, is made by means of a standard screw connection.
