Definitions

  • the invention relates to a contact protection device for a protective contact socket using a longitudinal slide with directly molded return spring according to the preamble of claim 1.
  • the invention may, for example, in Flush-mounted sockets can be used.
  • DE 2 402 569 A which is the closest prior art is considered a technique, is a contact protection device for a lancet insert seconds, in which the Longitudinal slide is held in a closed position via separate return springs.
  • the invention has for its object to provide a contact protection device Longitudinal slide for a protective contact socket of the type mentioned above, which is fully automatic mountable.
  • the achievable with the present invention consist in particular that in the proposed contact protection device, the number of parts used as well the parts and assembly costs are kept very low. It is not necessary, to manufacture and assemble a separate return spring.
  • the proposed longitudinal slide is formed largely symmetrical, so that this also a relief during assembly results.
  • the longitudinal slide has no protruding, during fully automatic mounting for hooking prone sections.
  • Fig. 1 is a schematic representation of the components of the contact protection device shown. It is the back of a socket insert 1 (C-disc) one Earthing contact socket to recognize, with at this back a contact protection lower part 2 formed - preferably integrally formed - is. Further Main components of the contact protection device are a longitudinal slide 11 and a contact protection cover 19.
  • the contact protection lower part 2 has a (also serving to attach the base) central pin 3 with locking connection 4, which in a corresponding Bore 20 of the contact protection cover 19 engages, either by the snap connection (snap connection) itself or by means of additional suitable Attachment (for example, a mother) a positive connection between contact protection lower part 2 and contact protection cover 19 takes place.
  • longitudinal slide 11 In the interior between contact protection lower part 2 and contact protection cover 19 inserted longitudinal slide 11 is between a closed Position (rest position) and an open position (with plug inserted) movable.
  • the contact protection lower part 2 has a cam 6 for fixing a U-shaped, connected to the main body return spring 13 of the longitudinal slide 11.
  • lateral Guide walls 7, 8 and frontal boundary walls 9, 10 of the contact protection lower part 2 serve to guide and limit the longitudinal movement of Longitudinal slide 11. Accordingly, the longitudinal slide 11 corresponding thereto Side walls 14, 15 and end boundary walls 16, 17 on. In the closed position, the main body of the longitudinal slide 11 covers the plug openings completely off.
  • the longitudinal slide 11 is a 2K injection molding (two-component injection molding) executed.
  • the hard component formation of the main body
  • the elastic or soft component formation of the Return spring
  • elastomer thermoplastic elastomer or Silicone formed.
  • the longitudinal slider 11 has a central opening 12 in its main body, which in the closed position, the pin 3 of the contact protection lower part 2 surrounds. Able edges 18 of the longitudinal slide 11 in its contact protection lower part 2 facing surface serve to engage in corresponding recesses the contact protection lower part 2 and thus for locking in one-sided loaded Longitudinal slide 11.
  • Fig. 1 are further plug openings 21 in the contact protection cover 19 to recognize what the insertion of connector pins into the socket of the socket allow in the open position of the contact protection device.
  • Fig. 2 is a view of the contact protection device in the closed position shown (with removed shock protection cover).
  • the frontal boundary wall 16 of the longitudinal slide 11 is doing by the spring force to the Cams 6 cross-return spring 13 against the front boundary wall 9 of the Touch protection lower part 2 pressed.
  • the lateral guide walls 7, 8 of the contact protection lower part 2 allow precise locking / guiding of the side walls 14, 15 of the longitudinal slide 11.
  • the central opening (see paragraph 12 in Fig. 1) engages the pin 3.
  • the plug openings (see paragraph 5 in Fig. 3) remain closed.
  • the main body of the longitudinal slider 11 has formed as inclined planes engagement recesses for the plug pins of a plug on. Be both pins simultaneously in the plug openings (see paragraph 5 in Fig. 3) of the socket insert. 1 inserted, is against the spring force of the return spring 13 an axial movement of the Longitudinal slide 11 causes, which leads to the opening of the contact protection device.
  • Fig. 3 is a view of the contact protection device is shown in the open position (with removed protection cover).
  • the frontal boundary wall 17 of the longitudinal slide 11 is against the spring force of the Cams 6 cross-return spring 13 in the direction of the end boundary wall 10 of the contact protection lower part 2 is pressed.
  • the lateral guide walls 7, 8 of the Contact protection lower part 2 in turn provide the precise guidance of the side walls 14, 15 of the longitudinal slide 11 sure.
  • the plug openings 5 are open. After this Pulling out the plug, the longitudinal slide 11 moves - due to the Return spring 13 - automatically back to the closed position shown in FIG. 2.
  • the longitudinal slider 11 has offset edges at the edges of Engaging troughs, which in one-sided loaded longitudinal slide in the plug openings intervene and lock there. A longitudinal movement of the longitudinal slide is thus effectively prevented and the plug openings 5 remain closed.
