Definitions

  • the invention relates to an incandescent lamp socket with at least one incandescent lamp and contact means inserted therein, the connecting wires of the incandescent lamp (s) being electrically connected or being connectable to a circuit board or switch plate, contact channels being provided in a socket for receiving the incandescent lamp (s) and are open towards the circuit board or switch plate, contact means also being introduced from the incandescent lamp (s) into the contact channels and the contact channels, in particular their cross sections, being dimensioned such that contact tongues of the circuit board or switch plate together with the contact means in the respective contact channel Clamp fit or held or durable by means of elastic pressure force (preamble of claim 1).
  • Such incandescent lamp holders can be used, for example, on motor vehicles and in particular on switches and on instrument clusters there. It is necessary to accommodate a larger number of signal or indicator lamps, the majority of which Cases two light bulbs belong together.
  • One of the lamps shows the position of the respective switch with the associated switch symbol (e.g. "rear window heating") with the night lighting and the other, adjacent light bulb indicates whether the respective circuit (in the aforementioned example the connection of the rear window heating) is switched on or Not.
  • a socket made of elastic silicone rubber is known in which the light bulb is inserted.
  • the electrical connecting wires of the incandescent lamp were extended to contact wires which were positioned on the side surfaces of the socket which were accessible from the outside and were contacted there by contact tongues on the printed circuit board or switch plate.
  • the disadvantage here was that the contact wires on these externally accessible side surfaces of the socket had insufficient guidance.
  • the contact tongues of the switch plate came into contact with the aforementioned contact wires when the socket was inserted. However, if, for example, the contact tongues were displaced a little too far outwards and the contact wires a little too far inwards, it could happen that the desired perfect mechanical contact did not occur between the contact tongues of the switch plate and the contact wires.
  • Another example of an area of application of the invention is for game lights. Slot machines have a large number of such small lamps, so that the invention can also be used advantageously.
  • the socket is inserted into printed circuit boards there.
  • the invention is not limited to the two aforementioned areas, the equipment of motor vehicles and gaming machines.
  • DE-GM 9113176 provides that contact wires are guided from the connection points of the incandescent lamps into contact channels and are clamped there with contact tongues on the printed circuit board or switch plate.
  • the contact channels are either provided within the material of the socket, or they are located in slots in the side surfaces of the socket. These slots are covered on the outside by a border that surrounds the version.
  • the socket provided there consists of an elastic silicone rubber or equivalent material. In both cases, the contact tongues of the circuit board or switch plate are clamped within the contact channels with the respective contact wire.
  • the task or problem of the invention is to improve an arrangement according to the preamble of claim 1 compared to the incandescent lamp holder according to DE-GM 9113176, in particular in that it facilitates assembly and thus a reduction in manufacturing costs and especially if several light bulbs are to be brought into electrical contact with a circuit board or switch plate and to be switched on and off differently.
  • the socket on its base facing away from the incandescent lamp or incandescent lamps is mechanically connected to a contact board that the connecting wires of the incandescent lamp (s) with contact tracks of Electrical contact board are connected, the individual contact tracks are electrically insulated from one another, and that the contact tracks are provided with bendable contact tabs which fit bent into contact channels of the socket and can be clamped there with the contact tongues of the switch or printed circuit board.
  • the contact channels with the dimensioning of their cross-section guarantee that the respective contact means and the associated contact tongue are guided securely and are in contact with one another due to the clamping fit with the appropriate contact pressure, ie there is a perfect electrical contact between them.
  • the sockets of the incandescent lamp (s) can advantageously be inserted automatically into the respective printed circuit board, switch plate or the like by robots. This results in a considerable saving in manufacturing costs compared to the manual assembly previously used.
  • the contact channels can also in the embodiment according to the invention parallel to the longitudinal direction of the Incandescent lamp run. This longitudinal direction generally corresponds to the direction of insertion of the socket into a circuit board, switch plate or the like of the dashboard.
  • a preferred embodiment of the invention is the subject of claim 2.
  • this gives the possibility of switching each lamp for them, but also both lamps together.
  • the two light bulbs 1 and 2 are held in a socket 3, which consists of a hard plastic (hard plastic). This gives version 3 sufficient stability.
  • the incandescent lamp 2 can be rotated by 90 ° about the longitudinal axis 2 'in order to make assembly easier. Thus, their connections are not in the illustration in FIG. 1 recognizable.
  • the incandescent lamp 1 On the basis of the incandescent lamp 1 it is shown that its connecting wires 4, 5 are firmly connected, preferably soldered, to a contact board 6 at points 7, 8. At the same time, the light bulbs are held on the contact board 6. For this purpose, the connecting wires 4, 5 can be inserted through holes in the contact board 6. In the same way, those from the above Reasons not shown in the drawing connecting wires of the second light bulb 2 attached to the contact board and also electrically contacted. If necessary, the version 3 could also accommodate more than two, for example three incandescent lamps (also not shown in the drawing).
  • the contact board 6 is provided with contact tabs 9a to 9d, which first run in one plane with the contact board 6 (FIG. 3) and are bent from the aforementioned plane for their insertion into contact channels 10 to 13 of the socket 3 (FIG. 1).
  • Fig. 3 also shows the structure of the contact board 6 and the associated areas of the socket 3, in particular the aforementioned contact channels 10 to 13 in detail.
  • the contact channels 10 to 13 advantageously run parallel to the longitudinal direction or axis 1 ', 2' of the incandescent lamps.
  • the aforementioned contact channels 10 to 13 of the version 3 serve to receive the contact lugs 9a-9d explained in detail below. They are preferably provided on their outer sides with slots 27, the function of which is explained below.
  • the aforementioned contact channels are surrounded on their long sides by the material of the socket 3. Furthermore, they are open at their end faces lying at the top and bottom in FIG. 1, at least on the end face for the introduction of the contact tongues 21 ′ to be explained in more detail.
  • the contact board consists of several, in the present exemplary embodiment three contact tracks 14, 15 and 16, which are either applied to an insulating plate or are held together by insulating parts 17, 18 and 19 located between them.
  • This arrangement is attached to the base 3 'of the socket 3, for example, in the cross-hatched areas 20 by heat welding or heat sealing.
  • the individual contact tracks 14 to 16 and the insulation 17 to 19 are held together at the same time.
  • the contact board is thus on the lower side in Fig. 1, i.e. the base of the socket 3 facing away from the incandescent lamps 1, 2.
  • it can be inserted in a recess 3 ′′ of the socket 3.
  • the socket with its material is sprayed around the contact tracks and thus holds the contact tracks (not shown in the drawing).
  • the bendable contact lugs 9a to 9d are introduced as contact means in the bent state into the contact channels 10 to 13.
  • the above-mentioned slots 27 make production easier, in that the contact lugs 9a-9d are first produced in one plane with the contact lanes 14-16. After connecting the contact tracks to the socket, the contact tabs are bent upwards so that they reach the contact channels 10-13 through the slots 27.
  • This arrangement from the socket 3 with the incandescent lamps 1, 2 and the contact lugs 9a to 9d located in the contact channels 10 to 13 can be plugged into a circuit board or switch plate 21 shown in dash-dotted lines in FIG.
  • this is done by that the contact tongues 21 'are in the clamped position between the respective contact lugs 9a-9d and the outer wall of the associated contact channel which has the slot 27.
  • FIG. 1 Such a contact tongue 21 'is also indicated by dash-dotted lines in its insertion position below the contact channel 11, its insertion direction being indicated by the arrow 22.
  • the socket 3 can have one or more projections or positioning pins (not shown in the drawing) on the underside, which fit corresponding recesses in the circuit board or switch plate 21 and thus ensure the desired positioning of the socket with contact board relative to the circuit board or switch plate.
  • This also facilitates assembly, which can advantageously be done by means of auxiliary personnel by simply inserting the socket with the incandescent lamps, for example into a printed circuit board, switch plate or the like.
  • the aforementioned assembly can take place either in a factory or when the circuit board, switch plate or the like is located, for example, on the dashboard of a motor vehicle.
  • the contact tongues 21 ' In the inserted position, the contact tongues 21 'have pivoted the contact lugs 9a-9d against their own elasticity so that the contact lugs 21' are produced by the inherent elasticity of the contact lugs.
  • the contact channels, the contact lugs and the contact tongues are preferably dimensioned such that when the contact tongues are inserted into the contact channels 10-13, the contact tongues and contact lugs are clamped in the contact channels.
  • the following circuit of the incandescent lamps 1, 2 is provided: One of these two incandescent lamps is connected with one of its connecting wires 4, 5 at 23 to the first contact path 14 and at 24 to the third contact path 15.
  • the other light bulb is with a pole 25 connected to the second contact path 16 and with its other pole at 26 to the third contact path 15.
  • the contact tabs 9a, 9d belong to the first contact track 14, the contact tab 9c to the third contact track 15 and the contact tab 9d to the second contact track 16.
