Abstract

In order in a device for screening electromagnetic flows and the like, consisting of an electrical conductor which defines a surface and is made from copper or copper alloys, to achieve a permanent discharge, it is proposed that the conductor (1) has a terminal lug (4), that the terminal lug (4) is connected to the earth terminal (5) of an earthing-pin plug (6), and that the earthing-pin plug (6) exclusively has the earth terminal (5) and is constructed without a current contact. <IMAGE>

Description

"Device for shielding electromagnetic currents and the like."

The invention relates to a device for shielding electromagnetic currents and the like, consisting of " from an electrical conductor spanning an area made of copper or Copper alloys.

Such devices are known. For example, copper mats are used under carpets or also laid under the mattresses of bed-runners or the like to absorb electromagnetic currents or so-called earth rays, which are caused by water or earth veins, to shield. It is known that electromagnetic currents and / or so-called earth rays can lead to sleep disorders and other complaints, on the other hand this known device protects.

However, the known devices can only be used as Collectors act, whereby the capacity of the collector is limited, and a Knd charge of the collector so far not possible.

Proceeding from this, the invention is based on the object of providing a device of the initially described designated type, in which the electrical conductor spanned across the surface can be continuously discharged.

To solve this problem, the invention proposes that the conductor has a terminal lug, that the terminal lug is connected to the ground contact of a safety plug and that the safety plug has only the ground contact and is de-energized is trained.

To use the device with the safety plug plugged into a standard socket outlet, whereby the electrical conductor over the earth contact is connected to the earth conductors of the socket outlet, so that the electrical conductor collected rays and / or

Currents can be diverted via the earth conductor of the socket.

This increases the effectiveness of known devices Significantly improved of the type described above.

In a further development it is proposed that the electrical conductor take the form of a copper sheet having.

The terminal lug can be attached to the copper sheet be soldered, so that a simple production is possible.

Alternatively or in addition, it is provided that the electrical conductor is through a copper cable is formed, which is arranged in turns in the plane.

It is also advantageous if the electrical conductor is embedded in foam.

It is also advantageous if the conductor embedded in foam is surrounded by a cushion cover is .

It is preferably provided that at least the connection faia-n-e — is flexible.

the terminal lug and possibly also the electrical conductor can be made of flexible material, so that a good adaptation to the external conditions when laying such devices is possible. The devices can be the size of a seat cushion or the size of a mattress protector have so that, depending on the intended use, a correspondingly large-area shielding is possible. In a further development it is proposed that the protective contact plug have at least one plug pin made of electrically non-conductive material, which instead of the usual electrical contact pin is attached in the connector.

This means that the protective contact plug is arranged in a corresponding protective contact socket easier to reach, since the respectively. the

Connector pins can take on a guide function. The safety plug has no power contacts, so that no electrical connection between the Power supply and the electrical conductor of the device is made. . . Only a connection is established between the electrical conductor of the device and the earth contact.

An embodiment of the invention is shown in the drawing and described in more detail below. It shows:

The ! Device for shielding electromagnetic Flow and so-called earth rays essentially consist of an area spanning an area electrical conductor 1 made of copper, which in the exemplary embodiment is carried out by a copper cable with a 3 mm cross section is formed.

The conductor is embedded in foam 2 and surrounded by a cushion cover 3.

The conductor 1 is laid so that it follows the contour of the pillow-like device on the edge side and is also laid in a diagonal direction. Alternatively, a meandering layout could also be used of the copper conductor.

The conductor 1 is provided in the drawing figure 1 below with a terminal lug 4, which is made of flexible electrically conductive material. The connection lug is connected to the earth contact 5 a protective contact plug 6 electrically connected, the protective contact plug exclusively which has grounding contacts, but is otherwise designed without a current contactE.

In the exemplary embodiment, the protective contact plug 6 has two connector pins 7 made of electrically non-conductive material, such as plastic exist.

These pins are used to guide the safety plug when it is inserted into the corresponding -_ Earthing contact socket 8.

The invention is not restricted to the exemplary embodiment, but rather within the scope of the disclosure many times variable.

All new individual and combination features disclosed in the description and / or drawing are used regarded as essential to the invention.
