Definitions

  • the invention relates to a contact element for connecting loosely guided power supplies to a printed circuit board.
  • Such an electrical connection is required, for example, in the case of compact fluorescent lamps in which a discharge vessel with its four current leads is connected in an electrically conductive manner to a circuit board holding an electronic ballast and ignition device.
  • the circuit board with the ballast and ignition device is arranged in a housing which also holds the discharge vessel and which is provided with a base for direct connection of the unit to a supply voltage.
  • the individual lamp parts are heated to a processing temperature of more than 500 ° C.
  • an electrically non-conductive oxide layer forms on the current leads, which is a hindrance when these current leads are soldered to the circuit board holding the ballast and ignition device. So the oxide layer must be removed mechanically before the anyway time-consuming and costly soldering process. Cold solder joints between the thin power supply lines and the printed circuit board often emerged afterwards, which made laborious troubleshooting with corresponding rework necessary.
  • the object of the invention is to design the contact between the current leads of a discharge vessel and the circuit board to be firmly connected to it in such a way that a secure electrical connection is created, the current leads not having to be brought into a solderable state beforehand.
  • the contact element is fastened to the circuit board and is provided with at least one opening in which a current supply of the discharge vessel is clamped in a force-locking and contacting manner.
  • the opening is a hole whose diameter is smaller than that of the power supply.
  • the opening and one of the outer edges of the contact element is provided with an incision, preferably with an approximately wedge-shaped shape, which extends approximately up to the bore.
  • a simple slot-shaped incision can also lead to the bore, in which case the two halves formed above the bore must be bent out of their plane against one another in order to achieve the same advantageous result.
  • the incision can continue underneath the bore in a slot-like manner and open into a second bore. In this way, the clamping effect of the contact element and thus the contact for power supply can be further improved.
  • the contact element is provided with at least one preferably tapering pin-like extension, which is inserted into holes provided in the printed circuit board and fastened there by means of a soldered connection to the conductor tracks present here.
  • the downward tapering design of the soldering lug facilitates insertion into the hole in the printed circuit board provided for this purpose and on the other hand brings about the pre-fixation required for a good soldered connection.
  • the contact element 1 of Figure 1 consists of a hard brass sheet with a thickness of 0.5 mm. On the underside, two solder tags 2 and 3 are provided, which taper downwards. Their greatest width is about 1 mm and is adapted to the hole diameter of printed circuit boards. On the upper edge 4, the contact element 1 has a wedge-shaped incision 5, which ends in a first bore 6. Below the bore 6, the incision is continued as a slot-shaped incision 7, which in turn opens into a second bore 8. The size of the bores 6 and 8 is adapted to the diameter of the power supply 12 to be contacted (FIG. 2) in such a way that a non-positive and electrically conductive clamping connection is produced.
  • the contact element 1 by means of solder 9 the conductor track 11 applied to a printed circuit board 10 is attached in an electrically conductive manner.
  • a power supply 12 is clamped in an electrically conductive manner.
  • the introduction of the power supply 12 through the slot-shaped incision 7 causes the oxide adhering to the power supply 12 to be scraped off.
  • the reduced diameter of the bore 8 compared to the diameter of the power supply leads to a secure, tight clamping, so that there is also no need to isolate the power supply 12 from adjacent live parts.
  • each power supply line 12 being assigned its own contact element 1 on the printed circuit board 10.
