Definitions

  • the present invention relates to a feeding and supporting device for electric components, of the type comprising: a small connecting board; a plurality of electric connecting conductors operatively associated with said small board; a supporting element fastened to the small connecting board; at least one first electric component operatively associated with the supporting element and exhibiting at least two thread-like terminals arranged to be electrically connected to said connecting conductors; second electric components operatively engaged with the supporting element and electrically interposed between at least one of the thread-like terminals of the first component and one of said connecting conductors.
  • the present invention in the embodiment described, is conceived for making control panels having signal lights of the type usually associated with household electrical appliances, being obviously understood that the innovatory concepts herein disclosed may be also utilized for uses different from the described ones.
  • control panels of the type associated with household electrical appliances, lighting installations or other electrical apparatus the arrangement of signal lights suitably connected to respective electric circuits is usually provided for the purpose of informing the operator, through switching an or off of each of the lights, about the operating state of one or more electric members to which the control panel is interlocked.
  • said signal lights essentially consist of bulb microlamps suitably connected, upon interposition of electric resistors connected in series and/or in parallel, to respective connecting connectors arranged in the farm of a printed circuit on a small connecting board also having the function of mechanically supporting the microlamps.
  • Connection of the microlamps and respective electric resistors to the conductors arranged on the small connecting board can be carried out for example by directly welding thread-like terminals associated with the microlamps and/or the electric resistors on the small board itself.
  • a supporting element is provided to be associated with each signal light, which supporting element comprises a block of plastic material embodying appropriate contact elements for the operating engagement of the electric resistors, the thread-like terminals associated with the bulb microlamp being connected to said contact elements and being partly buried in the plastic material forming the block. Said contact elements are connected to a pair of terminals designed to be welded on the small connecting board made in the form of a printed circuit.
  • said problems are solved by providing a device in which all signal lights are associated, in a stable manner and by mere inserting operations to be carried in a completely automated fashion, with a supporting element to be engaged to the small connecting board by a snug fitting operation so as to obtain the simultaneous electric connection of all signal lights, without any welding and/or additional assembling operation being required.
  • the present invention relates to a feeding and supporting device for electric components, characterized in that said supporting element exhibits: at least one engagement portion defining a tubular housing in which the first electric component is inserted; at least one bottom wall obliquely intersecting the axis of said tubular housing and designed to get in contact with the thread-like terminals of the first component for arranging them according to an inclined orientation and guide them to the outside of the tubular housing through at least one outlet slot disposed at the end of the first bottom wall; at least one second engagement portion defining a coupling seat extending in the extension of the outlet slot and arranged to engage a second electric component for operatively connecting it between at least one of said electric connecting conductors and one of the thread-like terminals carried by the first electric component.
  • a feeding and supporting device for electric components in accordance with the present invention has been generally identified by reference numeral 1.
  • the device 1 comprises a small connecting board 2 with which a plurality of electric connecting conductors 3 is operatively associated, said conductors being connected to respective electric members to which the device 1 is interlocked, for example through connecting terminals 3a of known and conventional type, or through extensions of the conductors 3 themselves projecting from the connecting board edges.
  • Said electric members may also consist of switches, thermostats or similar operating devices directly associated with the device 1 and not shown as known and not of importance to the ends of the invention
  • the connecting conductors 3 essentially consist of respective elastic thin plates made of conductive material, suitably supported by respective ribs 4 projecting from the connecting board 2, as better clarified in the following.
  • a supporting element 5 is engaged by snug fitting to the small board 2 by hooking means not shown as made in known manner, said supporting element being advantageously designed to engage one or more of the first electric components 6, as well as second electric components 7 electrically interposed between one of the connecting conductors 3 and one of the first electric components 6.
  • each of the first electric components 6 is essentially formed with a bulb microlamp conventionally provided with two thread-like terminals 6a designed to supply the microlamp with current.
  • the second components 7 essentially consist of electric resistors provided with end caps 7a of conductive material at which contact with the respective connecting conductor 3 and one of the thread-like terminals 6a of the microlamp 6 occurs.
  • microlamps 6 and/or resistors 7 may be replaced by other electric components such as diodes, capacitors or the like, depending on requirements.
  • Each of the microlamps 6 is disposed in a tubular housing 8 defined within one engagement portion 9 exhibited by the supporting element 5.
  • This first engagament portion 9 advantageously has at least one bottom wall 10 obliquely intersecting the geometric axis "X" of the tubular housing 8.
  • a partition 13 associated with the first bottom wall 10 adjacent to the outlet slot 12 is interposed between the thread-like terminals 6 emerging from the slot itself, so that any possibility of a short circuit between said thread-like terminals is avoided.
  • each of the second engagement portions 15 may internally have at least one retaining lug 16 designed to abut on a shoulder 7b defined by the cap 7a made of conductive material associated at the end thereof with the resistor 7 so that said resistor, when fitting has occurred, will be retained in a stable manner in the corresponding coupling seat 14.
  • each of the second engagement portions 14 is an auxiliary slot 17 extending parallel to the "X" axis of the tubular housing 8 before the guide slot 12.
  • Each of the auxiliary slots 17 lends itself to advantageously engage the end of the corresponding thread-like terminal 6a associated with the micralamp 6 so as to retain said terminal according to a predetermined orientation.
  • auxiliary guide surfaces 18 converging towards the auxiliary slot itself away from the outlet slot 12 are defined in each of the coupling seats 14.
  • third engagement portions 24 may be provided, said portions consisting for example of fitting lugs externally projecting from the first bottom wall 10 and each designed to engage, by forced fitting, a third electric component that in the embodiment herein shown consists of an auxiliary electric resistor 25 arranged to get in touch with the connecting conductors 3 so as to carry out a connection in parallel between the thread-like terminals 6a of the corresponding microlamp 6.
  • the device 1 further comprises at least one front covering element 19 to be engaged to the supporting element 5, for example by snap fitting means generally denoted by 20 in Fig. 1 and not further described as known per se and conventional.
  • This front covering element 19 is provided, in known manner, with a plurality of signal lights 21, each arranged before one of the housing 8 so that light emitted by the corresponding bulb micralamp 6 may be visible from the outside.
  • the assembling modalites of the device described above mainly as regards structure are as follows.
  • the small connecting board 2 has the electric connecting conductors 3 disposed in the appropriate configuration so as to achieve a given circuit diagram for connection of the microlamps 6 and any eternal electric component, depending on the intended use of the device.
  • each of the microlamps 6 is first axially fitted in the corresponding housing 8. Concomitantly with this operation, the thread-like terminals 6a emerge from the slot 12 in an oblique orientation imposed by the orientation of the first bottom wall 10, and they introduce their ends into the auxiliary slots 17 formed in the second engagement portions 15.
  • resistors 7 can be axially fitted in the corresponding coupling seats 14. Following the execution of this operation, the thread-like terminals 6a, under the thrust of resistors 7 introduced into the corresponding seats 14, are such bent that they take an orientation perpendicular to the axis "X" of the corresponding housings 8. In this way, each microlamp 6 is engaged in a stable fashion to the supporting element 5 and, due to the orientation of the thread-like terminals 6a its coming out of the housing 8 is prevented even in case of accidental overturnings or shakings.
  • resistors 7 are fixedly housed in the respective coupling seats 14, by virtue of the interference action exerted by the retaining lugs 16 on the shoulders 7b defined by the corresponding caps of conductive material 7a arranged at the ends of the resistors themselves.
  • the supporting element 5 lends itself to undergo any manipulation that may be necessary or may take place during transportation, storage and following mounting without involving any risk of losing one or more of the electric components associated therewith.
  • the supporting element 5 thus arranged can be engaged to the corresponding small connecting board 2 by a mere snug fitting operation.
  • the simultaneous electric connection of all microlamps 6, the respective electric resistors 7 and auxiliary resistors 25, if any, to the connecting conductors 3 is achieved.
  • the elastic thin plates forming the connecting conductors 3 lend themselves to act on the respective resistors 7 by urging them towards the thread-like terminals 6a in register therewith so as to ensure an excellent electric continuity.
  • the supporting element 5 and the corresponding connecting board 2 will be therefore engaged, upon connection of the terminals 3a to respective electric circuits arranged in the apparatus, to the front panel 22 of a household appliance or other apparatus with which the device 1 is going to be associated This engagement operation will take place too with the aid of further fitting means 23 not described in detail as known and not of importance to the ends of the invention.
  • the present invention attains the intended purposes.
