Definitions

  • the invention relates to a socket and a base for a small lamp according to the preamble of claim 1.
  • German laid-open specification DE 44 01 487 discloses a socket and a base for a small incandescent lamp in accordance with the preamble of patent claim 1.
  • This document describes a version for a small incandescent lamp for releasable and fixable insertion into a socket which is adapted to the socket and has marginal extensions Opening a circuit board.
  • the electrical contacting of the small incandescent lamp is achieved by pressing the lamp connecting wires led to the resilient contact arms of the holder onto the conductor tracks of the printed circuit board.
  • the socket can be inserted and removed from both sides into the opening provided on the circuit board.
  • the socket has two different insertion mechanisms, namely a locking mechanism and a clamping twisting mechanism.
  • the construction and assembly of this version are comparatively complex.
  • the electrical contacts are designed as metallic sleeves and the socket according to the invention has metallic contact pins which are permanently attached to the printed circuit board and with the base contacts designed as metallic sleeves a detachable plug connection come in.
  • the contact pins of the mount advantageously each have a longitudinally extending gap which narrows when the contact pins are inserted into the metallic sleeves, so that the contact pins are clamped in the metallic sleeves.
  • the contact pins of the socket which are inserted in the socket contacts designed as metallic sleeves, are soldered onto the conductor tracks of the printed circuit board when the printed circuit board is initially fitted with small incandescent lamps.
  • the plug connection existing between the contact pins and the metallic sleeves is released by simply pulling the small incandescent lamp away from the printed circuit board or from the contact pins.
  • the contact pins dissolved during the initial assembly remain on the circuit board and form the lamp holder for the replacement lamp to be used.
  • the lamp holder according to the invention preferably consists only of the printed circuit board and the contact pins soldered onto the printed circuit board. The simplicity of their design is therefore unsurpassed.
  • the bulb of the small incandescent lamp is advantageously arranged in a fitting receptacle of the base.
  • the current leads led out of the lamp bulb are advantageously welded to the base contacts designed as metallic sleeves. This ensures reliable electrical contacting of the lamp and a secure hold of the lamp bulb in the base.
  • Figure 1 is a partially sectioned side view of a socket and a base for an incandescent lamp according to the first embodiment of the invention
  • FIG. 2 shows a plan view of the socket and the base for the small incandescent lamp from FIG. 1
  • Figure 3 is a partially sectioned side view of a socket and a base for an incandescent lamp according to the second embodiment of the invention
  • FIG. 4 shows a plan view of the socket and the base for the small incandescent lamp from FIG. 2
  • FIGS. 1 and 2 show the first exemplary embodiment of the socket according to the invention and of the base 3 according to the invention for a small incandescent lamp 1 which is provided for mounting on a printed circuit board 2.
  • the small incandescent lamp 1 stands on the printed circuit board 2.
  • the base 3 of the small incandescent lamp 1 is made of plastic and has a hollow cylindrical base sleeve 3a and a foot 3b, which is molded onto one end of the base sleeve 3a and for placement on the printed circuit board 2 loading is true.
  • the cylindrical axis of the base sleeve 3a runs perpendicular to the circuit board 2.
  • the essentially cylindrical lamp bulb 4 of the small incandescent lamp 1 is fixed in the base sleeve 3a.
  • the inside diameter of the hollow cylindrical base sleeve 3a is matched to the outside diameter of the lamp bulb 4, so that the cavity of the base sleeve 3a forms a fitting receptacle for the lamp bulb 4.
  • an incandescent filament 5 which is supplied with electrical energy by means of two power supply lines 6 led out of the lamp bulb 4.
  • the foot 3b of the base 3 is spread at right angles from the outer surface of the base sleeve 3a and is provided with two through bores.
  • a metallic sleeve 7 is arranged in each of these bores, each of which is welded to one of the power supply lines 6 and forms the electrical contacts of the base 3 or the small incandescent lamp 1.
  • the metallic sleeves 7 each hold a metallic contact pin 8, which are part of the socket and form a detachable plug connection with the sleeves 7.
  • the contact pins 8 each have a longitudinally extending gap 8b, which narrows when the contact pins 8 are inserted into the metallic sleeves 7, so that the contact pins 8 are arranged with a press fit in the metallic sleeves 7.
  • the contact pins 8 are each equipped with a support surface 8a, which rests on the printed circuit board 2 and is soldered onto a conductor track. In order to facilitate the establishment of the plug connection between the base contacts 7 and the contact pins 8, the free ends of the contact pins 8 opposite the contact surface 8a are pointed.
  • the contact pins 8 inserted in the metallic sleeves 7 are replaced with their Support surface 8a soldered onto the conductor tracks of the printed circuit board 2.
  • the plug connection existing between the metallic sleeves 7 and the contact pins 8 is released by pulling the small light bulb 1 with its base 3 off the printed circuit board 2.
  • the contact pins 8 soldered onto the printed circuit board 2 remain on the printed circuit board 2. Together with the printed circuit board 2, these contact pins 8 now form the socket for the replacement lamp 1 to be used.
  • the replacement lamp 1 is mounted with its base 3 b onto those already installed during the initial assembly Contact pins 8 attached.
  • the second exemplary embodiment shown in FIGS. 3 and 4 is a small incandescent lamp 11 lying on the printed circuit board 10.
  • This small incandescent lamp 11 has a glass, essentially cylindrical lamp bulb 12 which is sealed by means of a pinch 12a. Two are from the pinch 12a Power leads 13 lead out, which are electrically conductively connected to a filament arranged within the lamp bulb 12.
  • the small incandescent lamp 11 also has a trough-like base 14, in the trough-shaped recess of which the lamp bulb 12 is fixed lying. The trough-shaped recess is tailored to the lamp bulb 12.
  • two clamps 15 are formed on the base 14, between which the lamp bulb 12 is held in a clamping manner.
  • the trough-like base 14 is provided with two through holes arranged to both of the pinch 12a.
  • a metallic sleeve 16 is arranged in each of these bores, each of which is welded to one of the power supply lines 13 and forms the electrical contacts of the base 14 or the small incandescent lamp 11.
  • the metallic sleeves 16 each serve to receive a metallic contact pin 17, which are part of the socket and with the sleeves 16 enter into a detachable connector.
  • the contact pins 17 each have a longitudinally extending gap 17b which narrows when the contact pins 17 are inserted into the metallic sleeves 16, so that the contact pins 17 are arranged in the metallic sleeves 16 with a clamp fit.
  • the contact pins 17 are each provided with a contact surface 17a which rests on the printed circuit board 14 and is soldered onto a conductor track. In order to facilitate the establishment of the plug connection between the base contacts 16 and the contact pins 17, the free ends of the contact pins 17 opposite the support surface 17a are pointed.
  • the assembly is carried out here in the same way as in the first exemplary embodiment.
