Definitions

  • the invention also relates to a method for the manufacture of such lamps.
  • Lamps of this type and their receiving body (or base) are in themselves well known in particular from patent EP 310,792.
  • This design has the disadvantage that the welding, once carried out, does not allow to visualize the effectiveness of the crimping.
  • the subject of the invention is also the general method consisting in carrying out, on lamps of this type, soldering and crimping at separate locations.
  • the lamp according to the invention is intended in particular, but not limited to signaling by mounting on printed circuit boards, lamp cards or to serve as indicator lights.
  • Conductors (2) are used to supply the current, which support the luminescent body (1) and hold it in place, themselves being possibly caught in an adhesive. They come out at the base of the lamp bulb.
  • It also includes a plastic body (3) with a means for receiving the bulb (chamfered housing at the entrance allowing penetration and installation of the bulb without tightening).
  • a rib (4) at the bottom of the body allows a clear separation of the two wire outputs of the bulb thus avoiding the risks of short circuit.
  • a circular flange (5) makes it possible to come to bear on the printed circuit during the fitting of the lamp support.
  • Two diametrically opposed lugs (6) allow, once that the rotation in abutment against the supports (7) has been carried out, to maintain the support in place on its plate and in its housing, thanks to the holding force applied by the contacts (8).
  • An ergonomically shaped base (9) facilitates manual mounting of the assembly on the card as well as selection for automatic mounting.
  • Electrical contacts (8) made of a metallic and elastic material are axially aligned and inserted in housings provided for this purpose in the plastic body (3).
  • each of the contacts is fixed, for this reason, to one of the wire outputs by a crimping (10) then a solder (11), which are carried out so that they are offset one with respect to the other, this in order to avoid any harmful interaction between the two operations.
  • a curvature (12) is given at the base of the crimping on the contact in order to avoid any risk of cutting the wire outlets on the contacts at this location due to their curvature.
  • a resin is optionally injected into the bottom of the support through an orifice which may be provided on the bottom of the latter, after insertion of the "contact bulb” assembly into the body, or else, injected through the top of the support before insertion of the whole, all this in order to meet a possible specification, as regards the resistance to the extraction forces applied to the bulb.
  • a vertical fold (14) is made on the contact in order to avoid contact with the glass of the bulb, and therefore the stresses which may result.
  • An elastic beam (15) completed with a spherical stamp gives the necessary contact pressure on the circuit where the lamp is placed in order to ensure the electrical connection between the two.
