DE2336778A1 - Safety mains socket has dead contacts - which become live with plug insertion using insulated push rods - Google Patents

Abstract

The cylindrical contact shells in the socket are dead and only become electrically live when the plug is inserted. When inserting the plug into the socket a protruding push-rod of insulating material which rests on springy metal strips connected to the mains, pushes the latter strip onto one of two metal flaps at the bottom end of each cylindrical contact shell. The pushrods are protected against malfunction by locating them between guide projections at the bottom of the socket and in line with the contact holes in the socket bottom. The earthed snap-clamp of the socket is placed at right angles to this line.

Safety socket for the plug connection of electrical cables.

The invention relates to a safety socket for the plug connection of El ektr ο lines, in which the plug contacts (3) are not energized, but are only energized with the counterpart, δ em plug, especially for rooms in which power connections are available .

In such safety sockets, the plug contacts (3) are not energized and thus eliminate a source of danger for playing children.

In the current sockets - as they are in the trade - the plug contacts are live. TJm the risk of accidents for children to reduce, is a protective cap in the industry Trade that no longer makes the live contacts in the socket accessible. But the danger is that mostly after using the socket it is no longer closed with the protective cap out of forgetfulness. ' Another disadvantage is that the protective cap is a loose part is quickly misplaced or lost. The protective cap can easily be removed from the socket with a sharp object remove. Under these circumstances, the protective cap can only partially fulfill the task placed on it.

The invention is based on the object that when the counterpart of the plug is pulled out, the plug contacts (3) in the safety socket are not energized

This object is achieved according to the invention in that when. Insertion of the counterpart to the plug a detached, non-conductive pressure bole (1) a resilient plate (2) moved to a tab of the continuous on the underside two-lobed plug contact (3) and the plug contact of the Energizes positive poles.

To prevent a pointed conductive object from touching the plug contact (3) of the positive conductor and at the same time

the pressure pin (1) is pressed in after further training of the invention, the through hole (4) for the pressure bolt (l) between the two guide lugs (5) at the bottom of the Outer part horizontal to the vertical snap clamp (6) of the Arranged protective fiber and the two retaining clips (7) on the inner part are offset between the horizontal and vertical Axis.

The advantages achieved by the invention are in particular that the plug contacts (3) in the safety socket are not energized and the risk of accidents for children playing is totally excluded. The safety socket is designed so that it is interchangeable with the conventional sockets and the plugs on the market (Protective plugs and the flat Euro plugs) do not have to be modified. This is how you can create a Eliminate source of danger on simple mechanical v / ege.

An embodiment of the invention is shown in the drawing and is described in more detail below. Show it
