Definitions

  • the invention relates to a socket for a two-pin halogen lamp with a base which on the one hand has socket contacts for the halogen lamp pins and on the other hand has fastening parts for rigid alignment of the socket, in this case a current-conducting connection is provided between each of the fastening parts and one of the socket contacts.
  • the socket is fastened in a housing, for example a lamp housing.
  • the socket contacts are guided over wires for contacting fastening parts, which in turn are connected to the respective power lines for the power supply of the halogen lamp. This results in a time-consuming assembly, since the wires have to be connected to the socket contacts and the fastening parts. In the event of incorrect installation, the sockets are unusable without the fault being apparent at first glance.
  • the object of the invention is to design a version of the type mentioned in such a way that when the version is attached, the socket contacts at the same time to a Lei tion network, can be connected to conductive lighting parts or conductive parts of devices or devices for power supply. In this case, the power connection is inevitable, the conductive parts maintaining their mechanical function.
  • At least one of the current-conducting connections is a functional element of the socket, in this case the functional element is made of the same material and integrally with the contact surface for the lamp pins and / or the fastening part.
  • This provided current-conducting connection ensures that when the holder is held in a housing or on busbars in the fastening part, it is inevitably possible to make contact with the current conductors of a power network, so that after the fastening part of the socket, the socket contacts themselves are already connected to the power supply lines are. This results in a simple assembly, since overall a whole operation, namely the wiring of the socket independent of the fastening part, is spared, or the no longer necessary laying of connecting lines.
  • the functional element which is the fastening part, the socket contact or a part thereof, makes it possible to dispense with additional connection elements such as lines, terminals, flat plugs, pins or the like.
  • this design enables faults in the wiring of the lamp socket to not occur, since contact is inevitable when the socket is constructed. Finally, the number of components of the socket is reduced by this design, whereby the effort for production and assembly is reduced becomes.
  • the functional element is advantageously designed as a metallic stamped part and / or a turned part. This results in simple manufacture of the current-conducting connection. In addition, the assembly is further simplified.
  • the functional element be designed as a coating applied to the base in some areas. This coating allows the two current-conducting connections to be made on the base in a simple manner. This partial metallization or other conductive coating of the base results in inexpensive manufacture of the socket, as well as compulsory wiring.
  • the stamped parts or the turned parts and / or the coatings are formed in some areas as abutments for the halogen lamp pins.
  • a section of the stamped part is advantageously provided as a part resilient against a lamp pin. This results in a secure contact system for the pins of the halogen lamp. Nevertheless, inexpensive manufacture is given, since the resilient section can be integrally formed on the stamped part in one piece. The suspension could take place via a film-like hinge-like section of the stamped part.
  • functional elements extend in regions to the side of the base which receives the lamp.
  • the functional elements are arranged in regions on the side of the base which faces away from the side receiving the lamp.
  • the socket base itself is hardly enlarged in size, but nevertheless it forms a reliable guarantee that the lamp can be easily connected to the power lines.
  • the assembly of the socket itself is simplified because there is an easier way of contacting. It is also advisable for the functional elements to be arranged in regions on the outer surface of the base, since this considerably facilitates and increases the possibility of the fastening part and the production of the contact connection.
  • a screw, clamp and / or lock connection of the socket which is used to hold the socket, is provided on the fastening part of the base, with which power lines can also be contacted in the fastening part of the socket.
  • Such connections result in a simple fastening part of the socket, including its contacting to the power grid.
  • a particularly favorable manufacture of the socket results from the fact that one of the fastening parts and one of the socket contacts are arranged in a common, substantially planar base recess, seen in plan view, with the fastening part on one narrow side of the recess provided, while on the other narrow side of the rectangular recess a compression spring serving for contacting the lamp pins is supported.
  • This design allows simple manufacture and secure assembly of the socket, since on the one hand only a few components have to be inserted into the socket and on the other hand there is a clear arrangement.
  • the functional element is expediently designed as a hollow rivet provided with an internal thread serving for the fastening part, on whose outer jacket an abutment with the contact surface for a lamp pin is formed.
  • a functional element allows simple manufacture and assembly, with the rivet ensuring a secure fastening part of the holder and the parts of the holder.
  • the functional element can be produced as a turned part from a profile part, such as a profile rod, profile wire, whereby the production of the functional element is possible at low cost.
  • the socket 10 shown in FIGS. 1-3 serves to hold a two-pin halogen lamp 33. It consists of a base 11 which carries receptacles 14 into which socket contacts 15 can be inserted. The front with the receptacles 14 is covered with a mica plate 12. The mica plate can be fastened to the base by means of fastening parts 17, which are designed as rivets 18, the mica plate, as can be seen from FIG. 2, being provided in a front-side depression of the base 11. The mica plate is provided with insertion openings 13 for the pins 34 of the halogen lamp 33, in this case the pins 34 engage in the socket contacts 15 for making contact.
  • the socket contacts 15 from a movable plate 20, which is pressed by a spring 16 against an abutment 21.
  • a pin 34 of the lamp 33 engages between the movable plate 20 and the abutment 21 of a socket contact.
  • the abutment is provided with groove-like depressions 22, in which the pins 34 of the halogen lamp 33 are inserted in regions for the purpose of guidance and contacting.
  • the groove-like depression forms a contact surface 31 for the pin 34.
  • the abutment 21 is designed as an angled portion of a metallic stamped part 23, here, as shown in FIG. 2, the main part of the stamped part leads to the metallic rivet 18 with which the mica plate is held .
  • the stamped part 23, with the abutment 21 and with the contact surface 31, forms the functional, unitary, one-piece functional element via which the current-conducting connection is made.
  • the main part of the stamped part 23 leads to the fastening part 17 of the base and contacts this rivet-like fastening part.
  • the fastening part is arranged in an opening 24 running between the two strins of the approximately cylindrical base of the stamped part 23 arranged.
  • the opening 24 receives the rivet 18, which holds and contacts the stamped part 23 arranged in the recess 25.
  • the fastening part 17 or the rivet 18 is provided with a thread 26 on the inside in the two exemplary embodiments shown. About screws 27 is then the base with the two rivets 18 can be fastened to conductor rails 28. This is followed immediately by the contact from the conductor rails 28 via the rivets 18, the metallic stamped parts 23 to the socket contacts 15, to the abutment 21.
  • the pins 34 of the halogen lamp 33 are inserted into the openings 13, then - after the lamp has been fastened to the conductor - the lamp itself on the mains.
  • the current-conducting connection from the fastening part to the socket contacts takes place via the stamped parts which are located on the rear side of the base, that is to say on the side facing away from the lamp.
  • the power supply takes place via the stamped parts 23, which are arranged on the front of the socket, that is to say on the side on which the insertion openings 13 are provided.
  • the stamped parts and the base receptacles are covered by a mica plate 12, the insertion openings 13 of which lie exactly above the socket contacts.
  • the mica plate at the same time closes the socket receptacles 14, so that the socket contacts located therein are secured against falling out.
  • the halogen lamp 33 is shown in dash-dot lines in FIG. 1.
  • the base receptacle for the socket contacts is designed as an essentially rectangular base recess 32. This base recess ends on one narrow side in the area of the opening 24 for the rivet 18.
  • the socket contact 15 is inserted into the base recess, specifically with the rivet 18, the Wi derlager 21, the movable plate 20 and the spring 16.
  • the rivet 18 with the abutment 21 and its contact surface 31 is made of one material and in one piece. In this embodiment, the rivet with the abutment and its contact surface forms the current-carrying functional element.
  • the spring 16 is supported on the end of the base-like recess 32 opposite the rivet 18, so that the movable plate 20 is always pressed against the abutment 21 or the pins 34 of the halogen lamp 33.
  • the abutment and the movable plate 20 are provided with insertion bevels for the pins 34.
  • the functional element is designed as a turned part and is manufactured from a profile part.
  • the abutment with the groove-like recess is already on this profile part.
  • To produce each individual functional part a section is now exposed from the profile part, the rivet then being produced during the production by means of a turning and drilling process.
  • the two free ends are then bent over for fastening, as shown in FIG. 7.
  • the thread is also made.
  • the base recess 32 has lateral widenings 35.
  • Paragraphs 36 of the functional element 36 engage in these widenings to secure the position. These paragraphs were already included in the profile section.
  • the illustrated embodiments are only examples of realizations of the invention. These are not limited to this. Rather, there are still many changes possible, be it in the shape of the base of the socket - this could also be rectangular or hexagonal, for example when viewed from above; - be it with regard to the current-conducting connection - this could also be formed from a coating instead of the stamped part, which is applied directly to base areas and extends from there to the base receptacles up to the fastening part; - or finally with regard to the type of fastening part - instead of the screw fastening part shown, a clamp fastening part or a grinding fastening part could also take place, for example in that a pin-like projection is provided on the fastening part, which engages in a sleeve-like connecting terminal, in this case the current transmission would take place via pins ; in the case of a sliding connection, the base with its fastening part could be pressed against a system of a light housing via a screw
  • the functional element could also be made of the same material and in one piece with the plate of the socket contact, in which case the plate would be attached to the stamped part via a type of film hinge.
  • the plate then has the contact surface for the lamps pencils.
  • the frame has a diameter that is less than 20 mm.
  • the mounting part and thus the lamp is aligned and thus always points in a selected direction, the direction being adjustable and definable as desired.
