Socket with protective device against touching live parts

The innovation "relates to a socket with protective device against touching live parts.

The usual outlets have the disadvantage that the live parts readily accessible from outside are = There are especially many become accidents are known in which children with electrically conductive parts, these ⁿ on externally accessible live parts touched and have electrified it. The electrically insulating protective caps used today to cover the live parts only have a limited protective effect, since experience has shown that they are often not reinserted after the socket has been used. In addition, the children often manage to remove these very easily attached guards.

It is the task of the innovation to provide a highly safe one that does not require any additional attention from the operator Establish socket outlet with protective device against touching live parts throughout Structure deviates as little as possible from the usual socket and can therefore be exchanged for this without difficulty can.

To solve this problem, it is proposed according to the innovation. that only by inserting one of the socket

the connector certain moving parts of the üteckdcee in such a way

* moved out of their original position so that they are dnin i "i

Actuate the contacts inside the socket through which the Voltage is also supplied to the externally accessible parts provided for the power line.

This is advantageously achieved in that the deflections of the protective contact brackets caused by the insertion of the plug close the contacts and that to increase safety only when both protective contact brackets are deflected at the same time, the externally accessible parts intended for the power line are energized. It is important that the pivot points for the protective contact bracket flo are arranged that, on the one hand, the deflections of the protective contact bracket caused by the insertion of the plug into the socket, the pressure bodies are moved to such an extent in the direction of the contacts that a. secure contact is made between the contact springs and the contacts and, on the other hand, when these processes are reversed, an air gap is created between the contact springs and the contacts of such a size that a voltage-related flashover is definitely ruled out v / earth. Show it:

Will turn into an after Pig. 1 trained socket a plug introduced by moving in direction 1, it will push the protective contact bracket 2 apart with the help of its protective contacts, which accordingly execute a movement around the pivot point. Through this rotary movement, the Pressure body 4 together with the contact springs 5 against the Contacts 6 are moved until there is a secure contact between the contact springs 5 and the contacts 6. Like Pig. 1 can be seen, thereby the at the clamping screws 7 to

Available voltage across the busbar 8, the Contact spring 5 and the busbar 9 to the contact sleeve directed. So that the parts that are accessible from the outside and intended for the power line are also energized.

Like the Pig. 2 shows the lever 11 is advantageously designed so that two pressure bodies 4 on one attached to a surface 12 formed part of the lever i1 will. The contact springs 5 are made in a simple Yfeise a molded piece 13 made of insulating material is held securely. In the base body made of a suitable material there are also those for receiving the fastening screws provided holes 15. With 16 is the connection to the protective contact line designated clamping screw.

Of course, from the exemplary embodiment explained in more detail here deviated from without leaving the scope of the intended property rights.

Socket with protection against contact Live parts, characterized in that only when a socket corresponding to the socket is inserted Plug certain moving parts of the socket so moved from their original position v / ground that they Actuate contacts 15,6) inside the socket, through which the voltage is also supplied to the externally accessible parts (10), which are provided for the power line. 2. Socket nJ.t Protective device against touching live Parts according to claim 1, characterized in that protective contact brackets (2) are arranged so that the Deflections of the protective contact bracket (2) caused by inserting the plug close the contacts (5, 6). / 3. Socket with protective device against touching live Parts according to claim 2, characterized in that the contact springs (5) are arranged so that only at simultaneous deflection of both earthing contact brackets (2) the externally accessible parts (10) intended for the power line are energized »/ 6b 0 2544 4. Socket with dc use precautions against touching live Parts according to Claim 3, characterized in that the pivot points (3) for the protective contact bracket (2) are arranged in this way are that, on the one hand, the deflections of the protective contact bracket caused by the insertion of the plug into the socket (2) the pressure body (4) to such an extent in the direction of the Contacts (6) are moved so that a reliable contact between the contact spring (5) and the contacts (6) is achieved and, on the other hand, when these processes are reversed, an air gap of such a size arises that a tension avoidance is excluded will,- -----
