Definitions

  • the invention relates to a touch protection device for a protective contact socket using a longitudinal slide with a direct molded return spring according to the preamble of claim 1.
  • the invention can for example Flush-mounted sockets are used.
  • the invention has for its object to provide a touch protection device Specify longitudinal slide for a protective contact socket of the type mentioned, which can be assembled fully automatically.
  • the advantages that can be achieved with the invention consist in particular in that 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 largely symmetrical, so that this is also a relief during assembly.
  • the longitudinal slide has no protruding, during the fully automatic assembly, sections that tend to get caught.
  • FIG. 1 shows a basic illustration of the components of the contact protection device shown. It is the back of a socket insert 1 (C disc) one Earthing contact socket can be recognized, with a lower part on the back protecting against accidental contact 2 is formed - preferably integrally formed. Further Main components of the contact protection device are a longitudinal slide 11 and a touch protection cover 19.
  • the contact protection lower part 2 has a (also used to fasten the base) central pin 3 with locking connection 4, which in a corresponding Bore 20 of the contact protection cover 19 engages, either through the snap connection (snap connection) itself or by means of additional suitable Fastening means (for example a nut) a positive connection between the contact protection lower part 2 and the contact protection cover 19.
  • the in the interior between the lower part 2 and the protective 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, return spring 13 of the longitudinal slide 11 connected to the main body.
  • lateral Guide walls 7, 8 and end walls 9, 10 of the contact protection lower part 2 are used to guide and limit the longitudinal movement of the Longitudinal slide 11.
  • the longitudinal slide 11 has corresponding ones Side walls 14, 15 and end walls 16, 17. In the In the closed position, the main body of the longitudinal slide 11 covers the connector openings completely.
  • the longitudinal slide 11 is a two-component injection molded part (two-component injection molded part) executed.
  • the hard component formation of the main body
  • the elastic or soft component formation of the Return spring
  • the longitudinal slide 11 has a central opening 12 in its main body, which when the position is closed, it engages around the pin 3 of the contact protection lower part 2. Stepped edges 18 of the longitudinal slide 11 in its lower part to protect against contact 2 facing surface are used to engage in corresponding recesses of the contact protection lower part 2 and thus for locking when one side is loaded Longitudinal slide 11.
  • Fig. 1 there are further plug openings 21 in the contact protection cover 19 to recognize which the insertion of plug pins into the socket of the socket allow with the contact protection device open.
  • the contact protection device 2 is a view of the contact protection device in the closed position shown (with the contact protection cover removed).
  • the front boundary wall 16 of the longitudinal slide 11 is by the spring force to the Cam 6 engaging return spring 13 against the end wall 9 of the Touch protection lower part 2 pressed.
  • the side guide walls 7, 8 of the lower part of the contact protection 2 allow precise locking / guiding of the side walls 14, 15 of the longitudinal slide 11.
  • the central opening (see number 12 in Fig. 1) encompasses the pin 3.
  • the plug openings (see number 5 in Fig. 3) remain closed.
  • the main body of the longitudinal slide 11 has engagement troughs formed as inclined planes for the connector pins of a connector. Become both connector pins at the same time into the plug openings (see number 5 in Fig. 3) of the socket insert 1 inserted, 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 shows a view of the contact protection device when the position is open (with the protective cover removed).
  • the front boundary wall 17 of the longitudinal slide 11 is against the spring force to the Cam 6 engaging return spring 13 in the direction of the end wall 10 of the contact protection lower part 2 pressed.
  • the side guide walls 7, 8 of the Lower part 2 for protection against contact in turn provides precise guidance of the side walls 14, 15 of the longitudinal slide 11 safely.
  • the plug openings 5 are open. After this Pulling out the plug moves the longitudinal slide 11 - due to the Return spring 13 - automatically back into the closed position according to FIG. 2.
  • the longitudinal slide 11 has offset edges on the edges of the Engaging recesses in the connector openings when the longitudinal slide is loaded on one side intervene and lock there. A longitudinal movement of the longitudinal slide is thus effectively prevented and the plug openings 5 remain closed.
