Definitions

  • the invention relates to a banana plug with a plug contact with an insulated tip and with a plug body which has an annular circumferential groove at the end on the contact side for holding an elastic ring.
  • the elastic ring inserted into the circumferential groove generally forms a color marking to distinguish poles of a power supply or different signal channels.
  • the rings usually also have a letter coding to identify the respective signal channel.
  • the banana plugs usually work together with sleeve-shaped contact sockets, which are located on cable switches or associated devices.
  • a problem with the known banana plugs of this type is that due to the touch of the not yet complete inserted plug contacts can endanger people or signal falsifications.
  • a particular source of danger is accidental insertion of the banana plugs into power sockets.
  • the problem underlying the invention is therefore to ensure protection against contact in a simple and inexpensive manner.
  • a banana plug of the type mentioned is characterized in that a step-like narrowed part of a sleeve is snapped into the groove of the plug body and surrounds the plug contact at a distance over substantially its full length.
  • the protection against accidental contact according to the invention is achieved in a simple manner in that, instead of the marking ring, the step-like narrowed part of a sleeve is snapped into the groove, which extends to the tip of the plug contact and surrounds it at a distance, so that a sleeve-shaped socket is inserted into the space between the sleeve and plug-in contact can be inserted to produce the contact.
  • the rigid sleeve which cannot be moved relative to the contact, provides complete protection against accidental contact with the fingers.
  • the sleeve in the region of the plug contact is provided with a longitudinal slot, which allows the sleeve to be adapted to manufacturing tolerances for the sleeve-shaped mating contact to a certain extent.
  • the longitudinal slot open towards the free end of the sleeve preferably extends to just before the end of the plug contact on the plug body side. Its width is expediently less than 1 mm, so that the protection against contact with fingers is not impaired.
  • a circumferential rib on the outer surface of the sleeve in the region of the step-shaped constriction.
  • the sleeve which is snapped on instead of the marking ring can be colored to take over the function of the marking ring.
  • a marking surface is embossed on the outside of the sleeve in the region of the groove, so that the corresponding channel coding is located at the usual location of the banana plug, despite the snap-on sleeve.
  • FIG. 1 shows a conventional banana plug 1, which is connected to a cable 2, for example by a welded connection.
  • the banana plug 1 has an essentially cylindrical, elongated plug contact 3, the metallic outer surface 4 of which can be provided with springs that are slightly curved outwards for improved contact.
  • the tip 5 of the plug contact 3 is formed from insulating plastic.
  • the connection of the plug contact 4 with the cable 2 takes place in a plug body 6, which has a waist 7 to facilitate its gripping and insertion into a plug socket.
  • the plug body 6 is provided with an annular circumferential groove 8 into which a marking ring (not shown) made of rubber-like, elastic material can conventionally be snapped.
  • a sleeve 9 shown in FIG. 2 is used with the banana plug 1 according to FIG. 1, which has a round cross section and is open on both end faces.
  • the sleeve 9 has a circumferential rib 10 on the cylindrical outer surface and a marking field 11 stamped underneath it.
  • the sleeve 9 can be snapped onto the plug body 6 by snapping into the groove 8, as a result of which the plug contact 3 is completely surrounded by the sleeve 9.
  • Figure 4 illustrates that the sleeve 9 has on its cylindrical inner surface a step-shaped constriction 12 with which the sleeve 9 is snapped over the edge of the groove 8 pointing to the plug contact 3.
  • the circumferential rib 10 is located at the level of the step-shaped narrowing 12.
  • the inner wall of the part of the sleeve 9 surrounding the groove 8 can widen conically towards its end in order to make it easier to slide the sleeve 9 over the edge of the groove 8.
  • the sleeve 9 can be colored in the same way as the marking rings originally intended for use with the banana plug 1.
  • the marking field 11 of the sleeve 9 can contain the same coding as the corresponding marking field of the elastic marking ring which is no longer used.
