Description

description . no the Power strip: The subject of the application power strip is used for supply and Extraction of electrical energy.

It is designed in the form of a skirting board. The power strip consists Made of flexible, current-insulating material (plastic) and can therefore be used in any room laid all around without interruption and manufactured in different colors.

In the front, upper edge, which is more convenient to use is beveled at the back, there are three, over the entire length of the power strip continuous slots (Fig. A-1) for the plug contacts (13).

Continuous and through the opening do not store in these slots directly accessible current conductors and earth phase (% +5).

The power strip offers innumerable tapping options at each desired location of the room.

Electrical power distributors in the form of baseboards or plug-in rail strips, which allow power to be drawn at any point on these strips, are already known; see USA patents 2 192: 899 and 2 23o 658, German patents 695 394 and 736 146, Austrian patent specification 2o6 96o and German utility model 1,842,872 Nevertheless, for the present invention "power strip" is a use ' Design protection sought because a patent granted the applicable German patent law is likely to conflict. The power strip should be accessible to utility model protection, since it has a significantly simplified improvement over the already known inventions, but increases the safety of electricity use.

Type of power consumption from the previously known constructions.

The power strip is on the German Patent Office since 11.162 present drawing in cross section and in approx. 5 times enlargement (Fig. A).

In this case it is intended for a multi-pole three-wire system. It can be used as a two-wire system or as a different system (e.g. radio or television antenna feed line). There is only one lflss1 in each room for the power strip connection to the power grid in the usual form through distribution dose required.

The all-round installation takes place without special angle or fitting pieces.

At the cut ends, the slots (1) of the power strip are through a supple, later hardening, permanently binding and current isolating compound elapsed.

The contact slots (1) for receiving the plug contacts (13) are located perpendicular to the sloping outer surface.

The contact slots (1) are angled again at their base.

In this part of the slot (1) the current conductors are stored and the earth phase = (4 + 5).

Because the conductors and the earth phase (4 + 5) offset to the slot opening run away, are playing children who use knives, scissors, knitting needles or metallic, Insert electrically conductive toys into the compact slots (1) to prevent damage electric current protected. You can use the introduced objects to break the conductors and do not touch earth phase (4 + 5).

The angled slot (1) is made according to the dimensions of the conductor (4 + 5) manufactured, since the cross-section of the current conductors (4 + 5) in each case according to the desired Amperage is to be selected.

The contact slots (1) are on the one facing the outer surface Side by two opposite ones that run the entire length of the power strip and rubber rollers (2) pressing against one another are completed.

These rubber rollers (2) prevent dirt and dust from entering and moisture in the contact slots (1).

The rubber rollers (2) 'are designed so that they dm, e contact slots close properly, but still inserting the plug without special Allow effort.

The conductors and the earth phase (4 + 5) are sunk and loose in their slots (see Pos. II).

Each conductor and the earth phase (4 + 5) consists of two halves (x + z), which are isolated from each other by a layer (y) but nonetheless firmly connected to each other are connected.

The halves (z) facing the contact slot openings made of copper and are the conductive phases. Their cross-section is accordingly to select the desired amperage.

At their upper ends, the halves (z) are shaped so that they can adapt to the current-consuming parts (v) of the grain tongues (13) with the largest possible area (see item I). lel3Ton rrsasnD3cX no. 3 This enables a good contact base and abrasion Lichen oxide layers reached at the contact points.

The other halves of the conductor and the earth phase (x) are the Carrier of the copper phases (z) and made of supple steel.

They are a little longer than the halves (z) so that they upper surfaces lying at the correct angle through the magnetic parts (u) of the Kontaktzungeh (13) are properly tightened and thereby the halves (z) into one can bring pressing connection with the parts (v) of the contact tongues (13).

The connector for the system shown here has three contact blades (13).

Eede contact tongues (13) consists of two firmly connected Divide (u = v). Between the upper parts made of iron or steel (u) and the lower one made of copper (v) is an insulating layer (y).

The insulating layer prevents electrical energy loss through Derivation into the halves (x) and the parts (v).

The upper parts (u) are magnetic.

After the plug is fully inserted, the ends are exactly @@@ over the recessed conductors and the earth phase (4 + 5) (see item I).

The lower parts (v) are used to remove and forward the electrical Current. They are shorter than the upper, magnetic parts (u). With the front The ends fit properly to the halves (z) of the conductor and the earth phase (4 + 5).

While the upper parts (u) are only attached in the connector housing are the lower parts (v) in the Steoker housing with the phases of the device cable connected in the usual way.

The contact tongues are wide and convex in shape (Fig. C).

Their size and width depends on the magnetic force that is required to make the ferromagnetic halves (x) the conductor and the earth phase to attract.

The magnetic forces of attraction then create sufficient contact pressure so that the necessary current strength without excessive heating or burning of the contact points for the electrical devices used in the household.

The contact tongues (13) also have semicircular grooves on both sides provided (14). The rubber rollers (2) snap into these grooves (14) when the plug has been fully inserted into the power strip (item I).

The plug must be firmly seated in the power strip. TelephoneFredenbaclt No. 3z The wide shape of the contact tongues (13) is sufficient Support surface for the rubber rollers (2) engaged in the semicircular grooves (14).

The convex shape also allows an immediate, risk-reducing The contact slots (13) are closed by the rubber rollers (2) on both sides of the contact tongues (13) to, As soon as the plug has been fully inserted into the power strip, the magnetic parts (u) of the contact tongues (13) are effective.

They attract the submerged conductors and earth phase (4 + 5).

The halves (x) adhere firmly to the parts (u) (item I) and press at the same time with sufficient pressure the halves (z) into the profiles of the parts (v).

A permanent, trouble-free circuit is closed because the construction creates the prerequisites for this and sufficiently large contact surfaces enable permanent contact.

The distance between the halves (x) and the parts (u), so the magnetic field of attraction is approx. 2 millimeters.

Pulling out the plug interrupts the circuit. the current conductors and the earth phase (4 + 5) are connected to the through the contact slot (1) and their angled resting slot stripped edge formed. Conductor and Earth phases (4 + 5) fall back and are stored sunk again in their slots (pos. II). The contact slots (1) are properly closed by the rubber rollers (2).
