Definitions

  • the present invention relates to a command or signaling device according to the preamble of claim 1.
  • a housing with rear contact tabs of this type is known for example from DE-A-26 37 617.
  • the cover does not have to be closed. It can be frame-shaped and completely open towards the rear. This is to ensure that the connection elements are even more accessible for testing purposes.
  • This known proposal has the disadvantage that the housing cross-sectional area is increased by twice the wall thickness of the cover. Such an enlargement of the housing cross-section is undesirable in microswitches and stands in the way of all constructive efforts to miniaturize the switches.
  • a control device of this type is also described in DE-C-587 373.
  • the cylindrical housing is provided with an external thread onto which the cover hood is screwed in the manner of a lock nut.
  • the conductors to be connected to the contact lugs are pushed through an opening in the cover hood separated from the housing and connected to the contact lugs. Then the cover is slipped over the ladder until it comes into contact with the housing and screwed onto it.
  • DE-U-8 332 474 shows in principle a protective hood that has the same effect and is to be attached in the same way as DE-C-587 373, with the difference that in the latter the protective hood is attached with a snap-in connection and not with a threaded connection over the connection contacts .
  • DE-U-7 501 663 shows a circuit breaker with mains connection terminals which can be protected against unwanted contact by a cover slide. This slide is, however, coupled to the shift lever in such a way that the mains connection terminals are only released from the cover slide for connection work when the shift lever is in the position.
  • US-A-3 754 205 shows a connector whose contact pins are protected by a hood in the idle state.
  • the hood is loaded by a spring and always has the tendency to slide over the connector pins. If the plug is pushed into a socket or plug socket, this pushes the hood back in the same amount as the plug pins penetrate it. This must be the case since the plug pins are usually live when the plug is inserted.
  • the invention according to the application wants to improve a protection against contact of the type mentioned, in such a way that on the one hand it does not enlarge the cross-section of the housing and on the other hand it does not lose any of the required protective function.
  • the invention is an optimal division of the space provided for the housing between the cutouts on the housing, the existing contact pairs and the connection contact tabs, so that all prescribed safety distances can be maintained in the smallest possible space.
  • the indicator light shown in FIGS. 1 and 2 has a translucent dome 1 in a front frame 2, to which a cylindrical housing 3 connects. This is provided for attachment to a mounting wall with an external thread 4 and a screwed nut, not shown, screwed thereon. At the end of the housing 3 facing away from the calotte 1, this is surmounted by two connecting contact tabs 5. The electrical conductors are connected to these (soldering, plug contact, etc.). In order to protect the terminal contact lugs 5 against contact after the conductors have been connected, a cover 6 is axially displaceable and captive in the housing 3. This has 5 openings 6 'in the extension of the terminal contact lugs.
  • the housing 3 there is also an axial guide 7 in which the cover 6 is guided axially displaceably with a guide pin 8.
  • the protective hood 6 is provided with two locking springs 9 with locking lugs 10, which limit the displacement path of the cover 6 in one direction and thereby limit it hold captive in the housing 3.
  • the detent springs 10 engage in two recesses 11 next to the guide 7.
  • the cover 6 can be displaced between the basic position shown with solid lines on the one hand and the protective position shown with dash-dotted lines on the other hand.
  • the recesses 10 and 11 each open a bore 13 which serve to receive the locking lug 10.
  • the recesses 11 are provided in the displacement path of the locking lugs 10 with a wedge surface 12 which serves to press the locking lug 10 inwards when the cover 6 is pulled outwards.
  • the indicator light described is mounted with the cover 6 in the basic position (shown with solid lines). After connecting the connection conductors to the contact lugs 5, the cover 6 is pulled outward into the dash-dotted protective position to protect against contact with these connection points, for which purpose a comparatively small force is required.
  • the locking lugs 10 slide over the wedge surfaces 12 and bend the locking springs 9 inwards against the guide 7. After the wedge surfaces 12, the locking lugs 10 jump into the bores 13 during further extraction and fix the cover 6 in its protective position. Pressing in the cover 6 is no longer possible without damaging it. If one wanted to push the cover 6 back into the basic position, the detent springs 9 would have to be compressed with a corresponding tool and the engagement of the detents 10 in the bores 13 would have to be released.
  • this protective hood 19 can assume three positions: The first position (item 1 in FIG. 4 on the left and FIG. 5) is the actual basic position, in which the base 20 of the cover 19 is close to the switching element 15 but at a distance from it. In this position, the terminal contact tabs 16 protrude through the openings 23 in the base 20 and are accessible and free for connecting the conductors.
  • the cover 19 In the second position (items 2, 3 and 5), the cover 19 is pulled out over the connection contact tabs 16, so that it protects them against undesired contact. In this second position, the cover 19 is at a greater distance from the switching element 15 than in the first position.
  • spring arms 26 arranged axially symmetrically on the cover hood 19, which engage behind a shoulder 28 on the outside of the switching element 15 with a claw 27, limit the pull-out of the protective hood 19 and determine its second position (item 2).
  • the tightening of the wedge flanks on the locking lug 30 determines (in addition to the elastic behavior of the spring arms 29) the force which must be exerted on the cover 19 so that it can be pushed back from the second position into the first.
  • the spring arms 29 thus prevent the protective hood 19 from being inadvertently reset from the second to the first position.
  • the four locking lugs 30 of the spring arms 29 overlap a shoulder 32 and thus determine the force required for pulling out the protective hood 19. An unintentional removal of the cover 19 is prevented; in other words, the spring arms 29 hold the cover 19 in the direction of the second position in a more limited manner Force firmly in the first position. In the opposite direction (ie in the direction of the third position), the covering hood 19 is held with limited force by the unlocking slide 21 resting against the lower end of the switch housing 14.
  • the spring arms 26 with the claw 27 in connection with the shoulder 28 limit the extraction of the protective hood 19 (and hold captively on the switching element 15), whereas the spring arms 29 with their locking lugs 30 (or their wedge flank inclination) and the interaction with the shoulders 31 and 32 determine the magnitude of the force with which the cover 19 can be brought from the first to the second position and from this back to the first position.
