Definitions

  • the invention relates to a socket for accommodating so-called H2 light bulbs, which have at their socket-side end two diametrically opposite and in one plane contact flanges, in which recesses are made for locking in the socket,
  • the socket body consisting essentially of a heat-resistant, in the reflector of a vehicle headlight or a vehicle lamp usable base plate is attached to which two pairs of conductive metal arms are attached, each of which forms a tab connector at one end and at the other end by means of trained there, approximately right-angled from the rest of the pair of metal arms parallel contact arms the contact flanges of the incandescent lamp so clamped between them that they are both locked in place and the electrical lead to them is made, while attaching the metal arm pairs to the base plate each a z between the two ends lying section is used.
  • each pair of metal arms is made of two parts, which must also have different bending and spring properties.
  • the arms of the metal arm pairs which form the holding rear wall must be rigid in themselves so that the light bulb takes up a correct position in relation to the base plate, while the other arms of the metal arm pairs, which simultaneously form the power supply and press the contact flanges of the light bulbs against the fixed arms, are resilient must be elastic.
  • the two pairs of arms are each attached to the base plate by rivets. This riveting process is not only an additional work step, but the rivet attachment also creates the risk of a malfunction in the long term, namely through unintentional loosening.
  • the contact arm of each pair of contact arms which lies at the front in the direction of insertion, bears against a wall of the mounting base plate that is perpendicular to the direction of insertion.
  • a bending-stiffening notch can be introduced into the bending line between each of the contact arms located at the front and the adjoining section lying against the base plate. As a result, this contact arm largely loses its elasticity and gives the light bulb a safe position.
  • one contact arm of the two contact arm pairs is convexly bent toward the contact flange of the incandescent lamp, while the respective other contact arm of the two contact arm pairs at the level of the convex deflection is one in embossed the sheet and as a contact point for the Has contact flange serving contact flange.
  • This contact nipple gives a significantly higher specific contact pressure than the contact pressure, which in the event of a bulb change also simultaneously destroys an oxide skin that has formed.
  • the socket for the H2 light bulb 1 which can be inserted into a reflector (not shown), consists of the base plate 2 made of insulating material, preferably ceramic, and the two contact devices 3 and 4 made in one piece from spring band steel.
  • the H2 incandescent lamp is a halogen incandescent lamp which has two diametrically opposed contact flanges 5 and 6 which run in one plane at its socket-side end. These two contact flanges are provided with recesses 7 and 8, which serve to lock the light bulb in the contact devices 3 and 4. So that the incandescent lamp cannot be rotated by 180 °, the recess 8 is designed as a round hole and the recess 7 as an elongated hole that is open on one side. Accordingly, the projections 9 and 10 engaging in these recesses are also embodied in the contact devices 3 and 4.
  • the projection 9 is designed as a tongue bent at right angles from the spring plate, while the projection 10 is designed as a deep-drawn sleeve with a round cross section.
  • the two contact arms 12, 13 of the contact device 3 are angled approximately at right angles to the same side and form approximately parallel to one another of the two pairs of contact arms into which the two contact flanges 5, 6 of the incandescent lamp 1 are inserted in a clamping manner.
  • the contact arms 12 and 13 are made narrower than the adjoining sections 14 and 15 of the contact device. These wider sections 14 and 15 are inserted like a drawer into lateral grooves 16 and 17 of the base plate 2. These two grooves hold the sections 14 and 15 together, so that the tab 11 does not open and the contact arm 12 does not spring back.
  • the contact device 3 is held in the base plate 2 on the one hand by the lateral grooves 16 and 17 and on the other hand by a resilient nose 18 of the metal arm resting on the base plate 2, which snaps into the recesses 19 of the base plate 2 in a barb-like manner.
  • the contact arm 13 of the contact device bears against a rear wall 20 of the base plate 2, as a result of which it is supported at least towards the rear.
  • the bending point toward the section 15 is provided with an indentation 21 which substantially stiffens the bending point.
  • This contact arm essentially forms a rigid arm against which the contact flanges 5 and 6 of the incandescent lamp rest.
  • the contact arm 13 is provided with contact warts 22, which are introduced as small impressions in the strip material. These contact lugs are arranged at the level of a deflection 23 introduced convexly in the contact arm 12, so that the contact pressure is directed at this punctiform elevation. This results in a specifically higher contact pressure.

Claims (5)

1. Douille pour recevoir des ampoules dites ampoules H2 (1), qui présentent, à leur extrémité côté douille, deux broches de contact (5, 6) diamétralement opposées, situées dans un plan et dans lesquelles sont rapportés des évidements (7, 8) pour blocage dans la douille, étant précisé que le corps de douille est essentiellement constitué d'une embase (2) stable à la chaleur, que l'on peut introduire dans le réflecteur d'un phare de véhicule ou d'un feu de véhicule et à laquelle sont fixés deux paires de bras métalliques conducteurs dont chacun, à l'une de ses extrémités, forme un raccord à broche plate (11), et à son autre extrémité, grâce à des bras de contact (12, 13) qui y sont formés, qui sont obtenus en repliant à peu près perpendiculairement l'autre partie de la paire de bras métalliques et qui courent à peu près parallèlement l'un à l'autre, bride entre eux les broches de contact (5, 6) de l'ampoule (1) de façon telle qu'elles sont bloquées en position et que l'alimentation électrique arrivant à elles est réalisée, tandis que c'est respectivement un tronçon (14, 15) situé entre les deux extrémités mentionnées qui sert à la fixation des paires de bras métalliques sur l'embase (2), caractérisée par les propriétés suivantes :
a) chaque paire des bras métalliques (12, 13) et le raccord correspondant à broche plate (11) sont découpés d'une pièce dans un feuillard élastique et pliés
b) le feuillard élastique est doublé par pliage écrasé, l'extrémité présentant le pli écrasé formant la broche plate (11),
