Definitions

  • the present invention relates to a protective contact socket (according to IEC60884), comprising a base with two spaced sockets, between which a central screw receptacle is arranged in the middle, and a socket pot with two guide grooves for a protective contact plug, the two guide grooves each formed by two parallel spaced projections are.
  • shockproof sockets are well known, the usual way on the socket pot projections which form the Statisticssnu th for the safety plug, with their respective end faces by about 3 mm from the leading edge of the socket pot are spaced.
  • a central screw bsymptom is provided between the two spaced sockets on the base, which is usually riveted into the base as a threaded sleeve.
  • a single fastening screw which is usually held in the area of the bottom of the socket pot, can be screwed to fasten the socket pot and a cover usually connected in one piece with it.
  • the socket pot can be screwed tight to the central screw receptacle despite the cover that can be pushed into the socket pot.
  • the assembly means can have an opening in the cover.
  • Such an opening enables a screwdriver to be pushed through the cover, so that the fastening screw can be turned for mounting the socket pot.
  • the opening can for example be selected so that a prescribed assembly tool, for example a Pozidriv screwdriver with a size index PZ1, can only be inserted through the opening with the screwdriver blade tip so that the screwdriver closes the cover at the same time against the force of the spring element when it is screwed in holding down.
  • the assembly means can have a thread-free screw insert which is arranged in particular on the rear of the cover.
  • a screw insert can serve as a transmission element between a screwdriver and the fastening screw, the opening in the cover always being closed or covered by the screw insert.
  • the screw bit has in such a case on its front an engagement profile for a screwdriver and on its back a handle profile for engagement with the fastening screw in the bottom of the Steckdo sentopfes, the screw bit freely rotatable either in the lid or attached to the back of the lid is.
  • the spring element can comprise two spaced-apart compression springs, which are each arranged in a sleeve molded onto the socket pot.
  • the springs are not only protected and guided. Rather, by means of two spaced and guided compression springs, good parallel guidance of the cover within the socket pot is achieved at the same time, so that it does not tilt or tilt when it is pushed in.
  • the cover can have at least one pin for connection to the spring element. As a result, the cover with the pin can be easily inserted into the spring or springs, so that the cover can be held on the springs at the same time with a friction fit.
  • the cover can have two parallel holding and guide arms which extend perpendicularly to the cover and which hold the cover against the force of the spring element in its not inserted position.
  • Such holding and guide arms serve, on the one hand, for uniform guidance of the cover within the socket pot.
  • such guide arms can be used as holding means to keep the lid in the aligned position in the peripheral edge of the socket pot when no plug is inserted into the socket.
  • the four parallel spaced projections which form the lateral guide grooves for the protective contact plug, are usually integrally connected to the socket pot.
  • these projections can, however, be formed by a separate component which is displaceably superimposed on the socket pot. In this way, it is possible to move the projections with their front end to the outer peripheral edge of the socket pot, so that when the cover is not inserted inside the socket pot - apart from the openings required for electrical contacts - a closed surface appears.
  • a manually detachable insert can be provided in the socket pot, which insert has a central mounting opening for the passage of a screwdriver and which fixes the cover in the inserted state.
  • Such an insert can serve as an assembly aid for the installer, as this allows the cover to be fixed in the pushed-in position when the socket top is screwed, so that the installer does not have to apply any force when pressing the cover down.
  • the insert can be released manually from the socket pot, for example by pressing two actuating flanks of the insert together so that it is released from the socket pot.
  • the lid can be provided with a closure, in particular with a closure flap, in order to cover or close the central assembly means.
  • a closure flap can be hinged to the lid, for example, by a film hinge or the like.
  • a rotatable contact protection can be arranged on the cover or on the base.
  • Such a protection against accidental contact can be rotated by inserting a plug, which releases the sockets. After pulling out the plug, however, the contact protection swivels back into its starting position, so that inadvertent insertion of objects into the sockets is prevented.
  • FIG. 3 shows a sectional view through a safety socket with a manually detachable insert
  • FIG. 4 shows an exploded view of a further embodiment of a protective contact socket
  • Fig. 5 is an enlarged exploded view of the lid and the
  • FIGS. 6 to 9 show sectional views through the embodiment of FIG. 4 with the cover pushed in at different distances.
  • Fig. 1 shows an exploded view of a first embodiment of a protective contact socket, which comprises a base 10, in which two electrically lei tend connection contacts with two sockets 12 and 14 are inserted, which are spaced apart in the base.
  • the base 10 is connected in a basically known manner to a support frame 16 made of metal and a grounding contact 18 is inserted into the base 10.
  • a threaded sleeve 20 is used, which attaches the ground contact 18 to the base 10 via a riveted joint.
  • the threaded sleeve 20 thus represents a central screw receptacle which is arranged centrally between the two sockets 12 and 14 in the base and which serves to accommodate a fastening screw 22 (Fig. 2) with which a socket pot 24 (Fig. 2) with the Base 10 is screwed.
  • Fig. 2 shows that the socket pot 24 is connected in a manner known per se to a piece with a cover 26, which connects flush and at right angles to the upper peripheral edge 28 of the socket pot 24.
  • the surface of the cover 26 does not have to be flat, but can also be curved or formed in some other way.
  • the se is mounted in the usual way by the support frame 16 is attached with the help of screws or claws to a wall or a mounting opening, whereupon the unit of socket pot 24 and cover 26 is placed on the base 10.
  • the cover 26 is previously set in a decorative frame 30.
  • the fastening screw 22 is inserted through an opening in the Bo to the socket pot 24 and with the central screw acquisition 20 screwed.
  • a rotatable contact protection 32 is provided in the area of the base above the sockets 12 and 14, which is rotatably mounted in a fold 34.
  • the contact protection 32 made of insulated plastic can be rotated against the force of a spring 36 when a plug is inserted into the sockets 12 and 14 and, after pulling out the plug, swivels back into its starting position in which the sockets 12 and 14 are covered to the outside are.
  • FIG. 2 shows that in the embodiment of FIGS. 1 and 2, a cover 40 that can be pushed into the socket pot 24 is provided.
  • This lid can by a safety plug when inserted against the force of two springs 41 and 42 to the bottom of the socket pot 24, the two contact pins of the plug being pushed through two openings in the cover 40.
  • the cover 40 is then pushed back by the springs into its starting position, in which the cover 40 is flush with the outer peripheral edge 28 of the socket pot 24.
  • the outer contour of the lid 40 is designed so that it can be pushed into the socket pot with little play, with two lateral projections 43 and 45 on the outer edge of the lid 40 sliding in guide grooves for the protective con tact plug.
  • these guide grooves 46 and 48 are each provided by two parallel spaced apart projections 50a,
  • Fig. 2 also shows that the socket pot 24 is provided with two spaced apart sleeves 54 and 56, the NEN for receiving the two compression springs 41 and 42, which act on the cover against the insertion direction with force.
  • the cover 40 In order to keep the cover 40 in its desired normal position, in which it is aligned with the outer peripheral edge 28 of the socket pot 24, the cover 40 has two parallel holding and guide arms 58 and 60 which protrude perpendicularly from the back of the cover 40 and which in the area of the projections 43 and 45 are attached.
  • the lower ends of the guide arms 58 and 60 are provided with an integrally formed hook 62 and 64, which the lid 40 in its desired The normal position holds if no plug is plugged into the socket outlet.
  • FIG. 2 shows one of two pins 66, which also protrude at right angles from the rear of the cover 40 to the rear, and which are inserted into the springs 41 and 42.
  • the cover 40 in the illustrated embodiment is provided with a mounting means which is axially aligned with the screw receptacle 20 in the plug-in direction in the assembled state, i. E. is arranged coaxially to the screw receptacle 20, and which enables a screw fastening of the socket pot 24 to the base 10.
  • the assembly means comprises an opening 68 provided in the center of the cover 40 for the passage of a screwdriver tip in order to screw the screw 22 into the screw receptacle 20.
