Definitions

  • the invention relates to an arrangement for attaching a test line to touch-proof covered, accessible via a cylindrical opening terminals of electrical devices.
  • the invention is intended to improve an arrangement of the type mentioned above such that a versatile test is also possible on any devices with little effort. This is achieved in a simple manner in that a permanent-magnetic, cylindrical intermediate part is inserted between the test line or test plug and the connection.
  • the intermediate part can be designed here as a bushing, but this is relatively difficult to manufacture as a permanent magnet. It is therefore more advantageous if a plug socket is connected to the permanent magnet on the outside of the base. In order to avoid spreading voltage outside the cover, it is advantageous if the permanent magnet and the plug socket are connected to one another via an insulating sheath. To ensure a safe transition, i. H. To ensure without large contact resistances between the permanent magnet and the socket, it is advantageous if a solderable layer is introduced between the permanent magnet and the socket.
  • a simple connection between the permanent magnet and the socket can be achieved if there is an opening on the outside of the bottom of the plug socket which is adapted to the outer contour of the permanent magnet and into which the permanent magnet is pressed with the interposition of a thin, conductive film.
  • the permanent magnet is designed as a screwdriver blade on the bottom side.
  • the intermediate part consists of cobalt and rare earths, preferably samarium.
  • the clamping screw 3 is screwed into the box terminal 4 indicated by dashed lines, which is connected to the actual connection 5.
  • An insertion funnel 6 is used to insert the connecting conductor into the box terminal 4.
  • the clamping screw 3 is not readily accessible from the cover side, so that it is not readily possible to check the connection to the test line 7 to which a test plug 8 is attached.
  • the arrangement 9 according to the invention for attaching a test line is connected to the test plug 8.
  • the arrangement 9 can be seen from FIG. 2. It consists of the permanent magnet 10 and the socket 11 for the test plug 8, which are connected to one another via a solderable layer 12.
  • An insulating sheath 13 serves as protection against contact and for additional mechanical holding. To carry out the test, only the magnet 10 needs to be passed through the opening 14 in the cover 2 in order to come into an electrically conductive connection with the head of the clamping screw 3. It can be seen that there is only one arrangement per end of the test line, whereas in the prior art there is a separate socket for each individual terminal. It is also easily possible to adapt the plug hole 15 of the socket 11 to the test line 7 or the test plug 8 to be used. Fig.
  • FIG. 3 shows a further embodiment of the arrangement according to the invention, according to which on the outside 16 of the bottom 17 of the socket 11 there is an opening 18 adapted to the outer contour of the permanent magnet 10, into which the permanent magnet 10 is pressed with the interposition of a thin, conductive foil 19 is.
  • the permanent magnet 10 according to FIG. 3 runs out in the form of a screwdriver blade 20 on the bottom side.
  • the thin, conductive film 19 consists for example of copper GAL SN.
