Definitions

  • the invention relates to a fuse holder with a Fuse status detector according to the preamble of the claim 1.
  • a fuse holder is from DE 41 27 214.5 A1 known.
  • the fuse holder can, for example, that known from DE 34 06 815 A1 Have shape or the shape known from DE 37 41 743.6 A1.
  • the latter is preferably according to the application DE 197 34 234.5 equipped with a coding tongue that is elastic at the foot contact of the fuse link.
  • This condition detector consists of a glow lamp, the one in the upper part of the fuse holder behind a window is arranged, and a small circuit board near the Glow lamp with those required to control the glow lamp electronic components such as capacitors, diodes and Resistors.
  • the status indicator is via connection lines electrically with the head and foot contact of the fuse link connected and shows by flashing the glow lamp when the fuse link has responded and is blown.
  • the electrical connection between the head and Foot contact of the fuse link and the board of the Condition detector made by small pieces of wire that on the one hand on the circuit board and on the other hand on contact elements were soldered to the fuse holder with the head or Connect the foot contact of the fuse link.
  • DE 35 13 833 C2 describes a fuse link known of a high cylindrical insulating body has, inside of which a fuse element between two the end faces of the insulating body arranged contact caps is provided, with a series connection of a high-resistance Resistor and an optoelectric display device is connected in parallel to the fuse element.
  • the high resistance can be made from an electrically conductive, high-resistance layer or from an electrically conductive, weaponomigen plastic insert consist of a Contact cap extends to the other and on the inner surface of the hollow cylindrical insulating material body.
  • the invention has for its object the fuse holder with built-in status detector so that the manufacture is simple. To solve this task looks the invention a fuse holder with the features of Claim 1 and a method for producing a Fuse holder with the method steps of claim 7 in front.
  • this object is achieved as in the claims specified, solved in that the connecting lines no longer consist of wire for the status detector, but from a conductive plastic, for which in the fuse holder, the rest of the insulating plastic exists, channels are provided, the precisely specified dimensions have.
  • connection lines for the status detector can be thus in the course of molding the fuse holder from plastic simply and through a so-called two-component injection design quickly.
  • the conductive plastic can directly with the head and / or Make sure the foot contact of the fuse link is in contact or indirectly via the metallic connections for the Fuse insert in the fuse holder.
  • Fig. 1 is a side sectional view Fuse holder 10 shown as usual Fuse switches are used.
  • the fuse holder 10 together with the fuse link 20 located therein, the is usually a fuse, not just for protection the consumer side against short circuits, but also for Disconnect the consumer side from the network, such as when working electrical installation is required.
  • the fuse holder 10 has an actuating handle 11 on, in which the circuit board 25 and the glow lamp 26 one Fuse status detector are housed.
  • the glow lamp 26 is behind a window 12 at the front, visible end of the operating handle 11 installed.
  • the electrical circuit of the status detector with the diodes, capacitors, resistors etc. to control the glow lamp 26 such that it flashes when the fuse link 20 is blown essentially on the board 25.
  • the fuse link 20 has a metallic Head contact 22 and a metallic foot contact 23.
  • the Head contact 22 of the fuse link 20 is with a metallic holding and connecting element 14 of the fuse holder 10 and the foot contact 23 of the fuse link 20th with a metallic holding and connecting element 15 of the Fuse holder 10 in connection.
  • the metallic holding and Connection elements 14, 15 serve the one hand, the Fuse link 20 elastic and replaceable in the fuse holder 10 to hold, for example the upper holding and Connection element 14 may include a compression spring 14a, and on the other hand, in the switch-on position the electrical Contact between the fuse link 20 and the corresponding Make connections in the fuse switch.
  • the circuit board 25 and the glow lamp 26 of the Status detector and the window 12 is the fuse holder 10 (without fuse link 20) made of plastic, the is brought into shape by injection molding.
  • the Connection line 16 made of the conductive plastic is by means of formed a two-component injection; she puts the Connection between the board 25 and the holding and Connection element 15 for the foot contact 23 of the fuse link 20 ago.
  • the connecting lines 16, 17 alternatively also directly to the head and Foot contacts 22, 23 of the fuse link 20 in contact stand, for example over protruding lugs on the housing the fuse holder 10 are designed so that they used fuse link 20 with its head or Connect foot contact 22, 23.
  • connection between the connecting lines 16, 17 and the board 25 is preferably carried out accordingly placed contact pieces 18 such that the board 25 only in inserted the intended cavity in the operating handle 11 needs to be, then automatically the electrical Contact between the circuit board 25 and the connecting lines 16, 17 is produced.
  • the channels for the connecting lines 16, 17 can be dimensioned such that a certain conductivity or a certain resistance results from the channel length and the channel cross-section together with the respectively provided type of conductive plastic.
  • the circuit on the circuit board 25 can be simplified in this way. Typical resistance values for the connecting lines 16, 17 are 10 3 to 10 4 ohms.
  • the connecting lines 16, 17 can also only partially conductive plastic are formed, especially if the other part of the connecting line 16, 17 approximately through a special configuration such as the holding and Connection elements 14, 15 can be realized.
  • the connecting lines 16, 17 are of course guided in this way or covered that no live contact Parts is possible.
  • FIGS. 2 and 3 show a second form of Fuse holder, designated by reference numeral 30 is.
  • This form is intended for a fuse that one has a separate on-off switch.
  • the fuse holder 30, like the fuse holder 10 takes a fuse link 20 with a head contact 22 and a foot contact 23.
  • the foot contact 23 of the fuse link 20 lies elastic to a coding tongue 35 which, depending on the nominal value of the Securing and thus diameter of the foot contact 23 different distances from the housing of the fuse link 20 protrudes as described in the application DE 197 34 234.5 is.
  • the fuse holder 30 apart from the metallic holding and Connection element 34, the board 25, the glow lamp 26 of the Status indicator and window 32 (without fuse link 20) made of injection molded plastic.
  • the electric insulating plastic for the housing of the fuse holder 30 is in the coding tongue 35, which is elastic at the foot contact 23 is present, a channel is provided which forms a first Connection line 36 with an electrically conductive plastic is filled out.
  • the connecting line 36 from the electrical conductive plastic is like the first form of Fuse holder by means of two-component injection educated.
  • the connecting line 36 runs as from the 2 and the view of the narrow side of Fuse holder 30 with the coding tongue 35 in FIG. 3 can be seen from the contact point of the coding tongue 35 with the foot contact 23 lengthwise through the coding tongue 35 and continue through the housing of the fuse holder 30 to Board 25.
  • connection line 37 here alternatively directly with the Head contact 22 of fuse link 20 are in contact.
  • connection between the connecting lines 36, 37 and the board 25 is preferably carried out again via contact pieces 38 such that when inserting the board 25 in the provided cavity in the upper part 31 equal to the electrical Contact between the circuit board 25 and the connecting lines 36, 37 is produced.
  • the channels for the connecting lines 36, 37 can also be dimensioned in this embodiment so that a certain electrical resistance of preferably 10 3 to 10 4 ohms results. Otherwise, 30 different plastics can be used for the two connecting lines 36, 37 in the fuse holder; and the connecting lines 36, 37 can only be partially made of conductive plastic.
