• eine Abdichtung des durch den Klappdeckel 6 abgedeckten Innenraums für den Fall, dass kein Stecker 24 in die Aufputz-Schutzkontaktsteckdose 1 eingesteckt ist.

A in the lower region of the housing cover 5 arranged laterally accessible lock 10 with sealed key insertion is used to lock the hinged lid 6 on the housing cover 5, wherein a lock is independent of whether a plug 24 is inserted into the socket 3 or not. Of importance is a sealed passage of a connecting cable 25 of the plug 24 by a hinge arranged opposite side wall of the hinged lid 6, which has a housing recess which forms a sufficiently large passage for a connection cable of an inserted plug when the hinged lid is closed. For this purpose, sealing means 8 in the region of the lower side wall of the hinged lid 6 and optionally additionally provided in the lower end region of the housing cover 5 are provided. This sealant 8 ensure

• a sealed implementation of the connecting cable 25 with the hinged lid 6 and
• a seal of the covered by the hinged lid 6 interior in the event that no plug 24 is inserted into the surface-mounted socket outlet 1.

Of course, as an alternative to the in Fig. 1 explained embodiment, housing lower part and housing upper part to be combined to form a one-piece housing.

In Fig. 2 is a plan view of a surface-mounted socket outlet with plugged plug shown. The position of the inserted plug 24 with connection cable 25 is sketched schematically. The hinged lid 6 encloses the plug 24 and allows by means of the sealing means 8 a sealed passage of the connecting cable 25 between hinged lid 6 and housing cover. 5

In Fig. 3 is a side view of a surface-mounted socket with a locking mechanism of the first embodiment shown. Characteristic of the locking mechanism of the first embodiment is that at least one locking lug 14 is arranged on the lower edge of the hinged lid 6 as a first locking means of the locking mechanism, which extends to the housing cover 5 back. The How it works is described below Fig. 4-6 explained. For the sealing between the housing cover 5 and the closed hinged lid 6, the lower edges of the hinged lid 6 are provided with a sealing means 7. Of course, this also applies to the locking mechanism of the second embodiment mentioned below.

In Fig. 4 is a plan view of a surface-mounted protective contact socket with a locking mechanism of the first embodiment shown with opened or removed hinged lid. There are the housing cover 5, the receptacle 3 and the plug openings 4 can be seen. Of course, the usual earthed with earthed sockets earthing strap are also provided. The arranged in the lower portion of the housing cover 5 locking mechanism 9 consists of the lock 10, which is in operative connection with an actuating pin 12 having at least one locking cam 13 as a second locking means. The housing cover 5 has a housing recess (slot) 15 in the immediate vicinity of the locking cam 13. After a matching key 11 has been inserted into the lock, the actuating pin 12 can be rotated through an angle of about 90 °, so as to effect unlocking / locking.

In Fig. 5 is a schematic diagram for explaining the locking mechanism 9 first embodiment shown in the locked position. The hinged lid 6 is closed. The locking lug 14 (first locking means of the locking mechanism) engages through the housing recess 15 into the interior of the housing cover 5. The lock 10 is rotated by means of the inserted key 11 to the right so that the locking pin 13 located on the actuating pin 12 (second locking means) is immersed in the locking lug 14, whereby suitably the hinged lid 6 is pulled in the direction of the housing cover 5. After removal of the key 11 from the lock 10, the actuating pin 12 is locked in the position shown, ie an opening of the hinged lid 6 is now not possible.

In Fig. 6 is a schematic diagram for explaining the locking mechanism 9 first embodiment shown in the unlocked position, the hinged lid 6 is closed. The locking lug 14 engages through the housing recess 15 in the interior of the housing cover 5 a. The lock 10 is inserted by means of the Key 11 turned to the left so that the locking pin 13 located on the actuating pin 13 slides out of the locking lug 14. After removal of the key 11 from the lock 10, the actuating pin 12 is locked in the position shown, ie an opening of the hinged lid 6 is now possible.

In Fig. 7 is a plan view of a surface-Schutzstecksteckdöse with a locking mechanism of the second embodiment with the open respectively removed hinged lid shown. Again, the housing cover 5, the socket pot 3 and the plug openings 4 can be seen. Of course, the usual earthed with earthed sockets earthing strap are also provided. The arranged in the lower portion of the housing cover 5 locking mechanism 16 includes the lock 10, which is in operative connection with an actuating pin 17 having at least one, here two locking cams 18, 19 (second locking means of the locking mechanism). The housing cover 5 has housing recesses (slots) 22, 23 in the immediate vicinity of the locking cams 18, 19. After a matching key 11 has been inserted into the lock, the actuating pin 17 can be rotated through an angle of about 90 °, so as to effect unlocking / locking.

In Fig. 8 a hinged lid used in the locking mechanism 16 second embodiment is shown. Characteristic of the locking mechanism 16 of the second embodiment is that at least one locking hook, here two locking hooks 20, 21 is arranged as the first locking means on the lower edge of the hinged lid 6, which extend to the housing cover 5 respectively extend.

In Fig. 9 is a schematic diagram for explaining the locking mechanism 16 second embodiment shown in unlocked position. The hinged lid 6 is closed. The locking hooks 20, 21 (first locking means) engage through the housing recesses 22, 23 into the interior of the housing cover 5. The lock 10 has been turned to the left by means of the inserted key 11 such that the locking cams 18, 19 (second locking means) located on the actuating bolt 17 are not in engagement with the locking hooks 20, 21. To Removing the key 11 from the lock 10, the actuating pin 17 is locked in the position shown, ie an opening of the hinged lid 6 is possible.

In Fig. 10 is a schematic diagram for explaining the locking mechanism 16 second embodiment shown in the locked position. The hinged lid 6 is closed. The locking hooks 20, 21 engage through the housing recesses 22, 23 in the interior of the housing cover 5 a. The lock 10 is rotated by means of the inserted key 11 to the right, that the actuating pin 17 located on the locking cams 18, 19 engage over the locking hooks 20, 21, whereby the hinged lid 6 is pulled in the direction of the housing cover 5. After removing the key 11 from the lock 10, the actuating pin 17 remains locked in the position shown, d, h. Opening the hinged lid 6 is now not possible.

In the FIGS. 11, 12 and 13 a locking mechanism 26 third embodiment is shown, not only allows a function "locking / unlocking the hinged lid" by means of a lock, but also when unlocked allows a user-easier to handle operation "locking / unlatching the hinged lid" on the housing cover, where characteristic of the operation "latching / unlatching of the hinged lid" is that there is no key to operate. It is in each of the Fig. 11, 12, 13th in each case a lateral section through the locking mechanism 26 and in the right-hand section of the picture in each case a view of the locking mechanism (with the housing cover 5 removed and hinged lid 6) shown in the left image section.

When locking mechanism 26 third embodiment, in turn, a lock 27 is mounted in the housing cover 5 of a surface-mounted protective contact socket, said lock 27 is in direct operative connection with an actuating pin 28. The lock 27 has a guided in a groove 30 in the housing cover 5 nose 29. Of importance is in addition to the rotational movement of the actuating bolt 28, an additional longitudinal displacement of the actuating bolt 28. At the actuation pin 28 at least two by a predetermined angle offset from each other arranged locking cam provided, said predetermined angle α in the shown Embodiment has the value 90 °. In the embodiment shown, a total of four locking cams 32 - 35 are attached to the actuating bolt 28, wherein the two locking cams 32 and 33 and the two locking cams 34 and 35 are offset by α = 90 ° to each other.

The FIGS. 11 and 12 show schematic diagrams for explaining the locking mechanism third embodiment of the operation "latching / unlatching of the hinged lid", ie after setting this operation, no operation of the lock 27 by means of a key longer required to open the hinged lid 6. Fig. 11 shows in the right part of the picture a (not shown) hinged lid 6 fixed web 36, which is provided at the end with a locking lug 37. When the hinged lid 6 is closed, the web 36 including the detent 37 engages through a housing recess of the housing cover 5 into the locking mechanism and the detent 37 engages behind the locking cam 32 so that opening the hinged cover 6 is initially impossible without further measures. In the left picture section the Fig. 11 is this latching inducing interaction between locking lug 37 and locking cam 32 also recognizable.

When pressing on the lock 27 - see the left in the picture section of Fig. 12 arrow direction A - results in a longitudinal displacement of the actuating bolt 28, wherein the actuating pin 28 end against a spring element 31, z. B. a coil spring, presses. The longitudinal displacement of the actuating bolt 28 is limited by the longitudinal displacement of the nose 29 within the groove 30. As a result of the longitudinal displacement of the actuating bolt 28 results in unlatching, since locking lug 37 and locking cam 32 no longer gegenübeliegen now. In the right part of the picture Fig. 12 It is shown that in this unlatched state, a lifting of the hinged lid 6 can be made from the housing cover 5 - see arrow B of the web 36th

As soon as no pressure is exerted against the lock 27, the spring force of the spring element 31 presses the actuating bolt 28 back into the in Fig. 11 shown starting position. If now the socket should be closed and therefore the hinged lid is pressed against the housing cover, so reach web 36 including locking lug 37 through the housing recess of the housing cover 5 in the locking mechanism and an inclined surface 38 of the locking lug 37 presses against the locking cam 32. The web 36 is formed of an elastic material, so that a transverse movement of the web 36 away from the lock 27 can take place - see the right in the image section of Figure 12 drawn arrow direction C - during which the locking cam 32 simultaneously slides along this inclined surface 38. Once the hinged lid 6 rests on the device cover 5, the web 36 springs back into its in the right image section of Fig. 11 shown initial state and it automatically adjusts the latching between locking lug 37 and locking cam 32, which is indicative of the latched state of the socket 1.

Fig. 13 shows a schematic diagram for explaining the locking mechanism of the third embodiment in the operation "locking / unlocking the hinged lid". In order to change the socket of the operation "locking / unlatching the hinged lid" in the operation "lock / unlock the hinged lid", it is first necessary to insert the key in the lock 27. Subsequently, a longitudinal displacement of the actuating bolt 28 is effected by pressure on the lock 27 so as to cancel the latching between locking cam 32 and locking lug 37. Thereafter, a rotation of the lock 27 by the angle α in the clockwise direction, here 90 °, whereupon a pressure relief can take place, d, h. the spring element 31 pushes the actuating bolt 28 back. The longitudinal movement and the rotational movement of the lock 27 are thereby guided by guiding the nose 29 in the groove 30 exactly. As soon as the key is finally pulled out of the lock 27, a locking pin 40 of the lock snaps into a blind hole 39 in the housing cover 5, whereby any longitudinal displaceability of the actuating bolt is removed when the key is removed. This results in the two sections of the image Fig. 13 illustrated locking between the locking cam 33 and the locking lug 37th

To unlock the socket, the key is first inserted into the lock 27, whereby the locking pin 40 is pulled out of the blind hole 39 back into the lock. Now can be solved by pressing the lock 27, the latching between the locking cam 32 and locking lug 37, ie the hinged lid 6 can now open. Once the key is removed from the lock 27, in turn slides the locking pin 40 in the blind hole 39. After the hinged lid 6 against the Housing cover 5 is pressed (and web 36 including locking lug 37 through the housing recess of the housing cover 5 engage in the locking mechanism), the inclined surface 38 slides along the locking cam 33. As soon as the hinged lid 6 rests on the device cover 5, the web 36 springs back into his right Image section of the Fig. 13 shown initial state and it automatically adjusts the latching between locking lug 37 and locking cam 33, which is indicative of the locked state of the socket.

The user can select whether he just wish a simpler operation "latching / unlatching the hinged lid" between the hinged lid 6 and cover 5 without any key operation or if he wants a secure operation "locking / unlocking the hinged lid" between hinged lid and socket with key operation. In the former case, he is the castle 27 first by means of the key in the in the 11, 12 bring shown position and the unlocking is now done in a simple manner by appropriate pressure on the lock, as above Fig. 12 explained. In the second case, he is the lock 27 by means of the key first in the in Figure 13 bring shown position and the unlocking is now possible only by means of key operation and appropriate pressure on the lock, as above Fig. 13 explained.

It goes without saying that the user can switch over a socket that has already been set to the "locking / unlocking the hinged lid" function at any time to the simpler function of "locking / unlatching the hinged lid". This is done with the key inserted by a rotational movement of the lock 27 by the angle α counterclockwise, while pressure on the lock 27 is exercised. As soon as the key is removed from the lock 27, the function "latching / unlatching the hinged lid" is automatically set, as in the Fig. 11, 12th is shown.

In the notes to the Fig.11,12,13 are always only cooperating with the locking lug 37 locking cam 32, 33 mentioned. The further locking cams 34, 35 act with a (not shown) further latching nose of a (not shown) further web of the hinged lid 6 in the same manner together. However, two locking cams 32, 33 suffice for the mode of operation itself.

In the Fig. 11,12,13 forms the lock 27 in the idle state (at relaxed spring element 31) a paragraph relative to the housing cover 5 and closes only with pressure and longitudinal movement of the actuating bolt 28 (see arrow A) flush with the housing cover 5 from. Alternatively, of course, an embodiment can be realized, in which the lock 27 in the idle state (with relaxed spring element 31) flush with the housing cover 5. When pressure and longitudinal movement of the actuating bolt 28 (see arrow A), the lock 27 then dips into the housing cover 5.

Of course, the specified angle α = 90 ° only by way of example, d. H. it can deviate also smaller or larger angles are used.
