Definitions

  • the invention relates to a socket for a power plug with at least two contact pins, having a base with a base face which has at least two holes, and with at least two contacts arranged behind the holes for electrically contacting a contact pin of the power plug inserted through the holes and one for Inserting the power plug provided collar, which on the base from a rear end position into one front end position, in which the collar projects further forward over the base face than in the rear end position and surrounds the base face like a collar, is movably mounted.
  • Such a socket with a movably mounted collar is, for example, through the WO 2020/077371 A1 known.
  • the collar is designed in the manner of a push button or push button, which is resiliently biased into its extended position by means of springs and can be temporarily locked in its retracted position by means of a releasable locking pawl.
  • the collar By tapping it in the retracted position, the collar can be released from its locking position on the latch and jumps into its extended position. Conversely, the collar can be moved from its extended position back into its retracted position by pressing it against the force of the springs and then locked on the locking pawl.
  • the present invention is based on the object of extending the collar in a different way in a socket of the type mentioned.
  • an extension mechanism which, on the one hand, engages the collar and, on the other hand, engages in the movement path of at least one of the two contact pins at least in the rear end position of the collar between the base face and the contacts and which is designed to move the collar through the at least one to extend the inserted contact pin from the rear to the front end position.
  • the collar is extended from the rear to the front end position by inserting the contact pins of the power plug into the socket.
  • the extension mechanism has a lever arm pivotably mounted on the base, which engages the collar at one end, in particular is articulated thereon, and at the other end projects into the movement path of the at least one contact pin, at least in the rear end position of the collar.
  • the lever arm is turned off by the inserted contact pin the movement path is deflected and the collar is extended - in the opposite direction to the contact pin.
  • the lever arm can, for example, be both pivotally mounted and guided in a longitudinally displaceable manner by means of a longitudinal slot on a bearing pin of the base.
  • the collar can be moved from the rear to the front end position against the effect of a restoring force, in particular in the form of a restoring spring, and is therefore biased into the rear end position.
  • a restoring force in particular in the form of a restoring spring, and is therefore biased into the rear end position.
  • the collar In the rear end position, the collar is preferably flush with the base face, resulting in a flat socket front.
  • the electrical connection between at least one of the contacts and an associated connection contact of a socket housing has an electrical switch actuated by the collar or the extension mechanism, which is open in the rear end position of the collar and closed at least in the front end position of the collar.
  • the electrical switch is only closed in the front end position of the collar, so that the contacts are only live when the collar is fully extended.
  • the electrical switch can have a contact spring that can be deflected by the collar or the extension mechanism, which is lifted from a mating contact of the switch in the rear end position of the collar and rests in an electrically conductive manner on the mating contact at least in the front end position of the collar.
  • the collar has on its inner circumferential side at least one protective contact that interacts with a protective contact of the power plug and is permanently electrically connected to a ground connection of a socket housing, for example by means of a sliding contact. This measure transforms the socket into a protective contact socket.
  • a socket housing has the base.
  • the socket housing can be circular or rectangular, in particular have a square outer contour.
  • the socket housing advantageously has complementary connection contacts on two opposite sides in order to be able to electrically connect two sockets to one another.
  • commercially available clamp or screw connections can alternatively be present on the socket housing and/or on the collar.
  • the invention also relates to a multiple socket with several sockets arranged along a row in a U-profile, as designed above.
  • the sockets and the U-profile preferably have mutually interacting guides, such as guide grooves and projections, by means of which the sockets are inserted into the U-profile and held therein.
  • the connection contacts of one socket advantageously contact complementary connection contacts of the other socket in order to forward supply lines from one socket to the next socket.
  • the invention also relates to a lighting device with at least one U-profile, in which a lamp and at least one socket or multiple socket designed as above are accommodated.
  • the lighting device preferably has a double U-profile, with the lamp being accommodated in one U-profile and the at least one socket or multiple socket in the other U-profile of the double-U-profile.
  • the lamp can, for example, have an LED strip that is glued into the U-profile and a transmissive light strip that closes the U-profile. Thanks to the double U-profile, the light and the socket(s) are spatially separated from each other. Depending on requirements, several sockets or multiple sockets as well as other modules can be inserted into the U-profile.
  • Socket 1 shown is used to electrically contact a power plug 2 ( Figs. 2a-2e ), which has several, here only two contact pins 3 as an example.
  • the socket 1 has a base 4 with a base face (plug base) 5, which has several, here two holes 6 , and with several, here two, contacts 7 arranged behind the holes 6 ( Figs. 2a-2e ), for example in the form of sockets, for electrical contacting of a contact pin 3 of the power plug 2 inserted through the holes 6, and one for inserting the power plug 2 provided, here only as an example of annular collar 8 .
  • the collar 8 is on the base 4 from the in Fig. 1a the rear end position shown in Fig. 1b shown front end position, in which the collar 8 protrudes further forward over the base face 5 than in the rear end position and surrounds the base face 5 like a collar, movably mounted. In its extended position, the collar 8 serves as contact protection for the contact pins 3 of the power plug 2 as long as they are not yet completely inserted into the holes 6.
  • the base 4 is formed by a socket housing 9 , which here only has a rectangular, in particular square, outer contour as an example.
  • the base face 5 is formed by the front of the socket housing 9.
  • the base 4 has several complementary connection contacts 10 on two opposite sides, here three connection plugs 10a and three connection sockets 10b ( Figs. 4a, 4b ) on.
  • the collar 8 On its inner peripheral side, the collar 8 has two protective contacts 11 , each interacting with an electrical protective contact of the power plug 2, here in the form of contact springs, which in each position of the collar 8 are connected to a ground connection of the socket housing 9, here with one of the connecting plugs 10a and with one of the connection sockets 10b, are electrically connected, for example by means of a sliding contact. Due to the leading protective contact 11, conductive housing parts of devices are grounded before the contact pins 3 reach the live contacts 7.
  • the outer contour of the base housing 9 can also be circular, for example.
  • the collar 8 in the rear end position is flush with both the base face 5 and the rest of the front of the socket housing 9.
  • the extension mechanism 12 has a lever arm 14 which is pivotally mounted on the base 4 and which is articulated at one end to the collar 8 and at the other end, at least in the rear end position of the collar 8, projects into the movement path of the contact pins 3.
  • the lever arm 14 is both pivotally mounted and guided in a longitudinally displaceable manner on a bearing pin 16 of the base 4 by means of a longitudinal slot 15 .
  • the lever arm 14 is preferably made of electrically non-conductive material.
  • the electrical connections between the contacts 7 and their associated connection contacts 10 can each have an electrical switch 17 actuated by the collar 8 or the extension mechanism 12, which is shown in FIG Fig. 3b shown, front end position of the collar 8 is closed and in all other positions of the collar 8 is open, as in Fig. 3a for the rear end position of the collar 8 is shown.
  • the switch 17 can, for example, have a deflectable contact spring 18 , which is attached to the contact 7 in an electrically conductive manner and whose free spring end rests electrically conductively on the connection contact 10 in the front end position of the collar 8 and is lifted off the connection contact 10 in all other positions of the collar 8 . This ensures that the contacts 7 can only be live in the front end position of the collar 8.
  • a multiple socket 20 composed of several, here three sockets 1 is shown, whereby in Fig. 4b all sockets 1 are inserted into a U-profile 21 and in Fig. 4a a last socket 1 has not yet been inserted into the U-profile 21.
  • the U-profile 21 has internal profile strips 22 on its two opposing profile legs and the socket housing 1 has longitudinal grooves 23 on two opposite sides, with which the socket housing 1 is guided on the profile strips 22 of the U-profile 21.
  • Figs. 5a, 5b show a lighting device 30 with a lamp 31 , with two sockets 1 and with a double U-profile 32 , with the lamp 31 accommodated in one U-profile 32a and the sockets 1 and further modules 33 in the other U-profile 32b of the double U-profile 32 are inserted.
  • the lamp 31 can, for example, have an LED strip which is arranged in the U-profile 32a and a transmissive light strip which closes the U-profile 32a.
  • the lighting device 30 is arranged on the underside of a wall cabinet 34 .
