Definitions

  • the invention relates to a relay, in particular plug-in relay, with a housing supporting the magnet system, with an armature held in its rest position by a spring device and with a test pin movably mounted in the housing for manual actuation of the armature, which test pin has one end on the armature or can be brought into contact with a part attached to this and holds the anchor in its working position in its working position.
  • test pin In known relays of this type, the test pin is held essentially perpendicular to the hinged anchor in a wall of the cap of the relay and can be moved against the hinged anchor.
  • the disadvantage of these relays is that the test pin cannot be fixed in its working position, which is very uncomfortable when checking a large number of such relays, in particular.
  • wire brackets have been provided in other known relays which are pivotally attached to the relay housing and which can be pivoted over the test pin in order to depress it.
  • the disadvantage of these known solutions is that this test and test bar always remains on the relay and is therefore available for misuse at any time.
  • such a bracket is inconspicuous and it is therefore very often forgotten to remove the fixings after the test in order to enable normal operation of the relays.
  • the invention therefore aims to avoid these disadvantages and to propose a relay of the type mentioned, in which the test pin can only be locked in the working position by an authorized person and where it is clearly evident whether the relay is in the test position or in normal operation is.
  • this is achieved in that a separate actuator from the relay for actuating the test pin is provided, which can be inserted into the relay and in its working position, in which it holds the test pin in its working position, can be locked with the relay and which can only be subjected to force is again separable from the relay.
  • the actuating device can be locked to the relay by a bayonet lock. This creates a key-like type of locking for the actuator, which is easy and quick to use.
  • An embodiment of the invention can be characterized in that the actuating device can be inserted at one end into the guide of the test pin and at this end has radially outwardly directed pins which can be inserted into recesses in the guide and upon rotation of the actuating device into the working position in the guide reach behind radially inward projections.
  • slotted surfaces projecting into the interior of the guide in the region of its outer end can be arranged on the guide of the test pin, between which recesses are provided, into which the actuating device has the corresponding, radially projecting pin is insertable.
  • the control of the test pin by the actuating device is ensured in a particularly simple manner by these measures. So the key can be inserted into the recesses and there after being twisted. As a result, the key is pressed down due to the inclination of the surfaces of the links, which also pushes the test pin down and thereby also brings the anchor into its working position.
  • each link section extend over an angle of e.g. extend almost 180 ° and each link section has two inclined surfaces with opposite inclinations, between which a surface extending perpendicular to the axis of the guide is arranged.
  • the actuating device can be locked by a quarter turn and can be released again by a further quarter turn, irrespective of the direction.
  • the recesses of the guide and the Pin of the actuator preferably have inclined side walls against the diametral of the guide or the actuator.
  • the test pin is rotatably held in the guide and is provided with at least one radially protruding pin which can be brought into contact with a link arranged on the guide with surfaces inclined against the axis of the guide and that at the end of the test pin facing away from the armature axially protrudes a projection onto which the actuating device can be plugged, which is provided with radially projecting pins which, when the actuating device is inserted, has a number of recesses corresponding to the number of pins of the actuating device, reach behind the flange facing inwards.
  • test pin is controlled during its rotation by the link arranged in the guide, the rotation being effected by the actuating device.
  • the inward-facing flange ensures that the actuating device cannot be removed in the working position of the test pin, but can only be removed when the test pin is in the rest position.
  • a resilient stop cooperating with the radially projecting pin of the test pin is provided, which defines a detent position corresponding to the working position of the actuating device.
  • test pin can be brought into abutment on an inclined surface of a butt part arranged on the hinged anchor.
  • the actuating device is designed as a key. This makes their function as a key clearly recognizable for the user.
  • the actuating device has a conspicuously marked, for example by colors or inscriptions, which preferably serves at the same time as a handle. This makes it very easy to ensure that an actuating device that is used is no longer overlooked after the tests have been completed and is properly removed again.
  • the guide runs essentially perpendicular to the base plate of the relay, as a result of which the actuating device can be used from the side facing away from the installation side of the relay, which is most easily accessible in most cases.
  • the relay has a base plate 1 in all embodiments, on which a magnet system 2 is held in a manner not shown, which has a hinged armature 3 held in its rest position by a spring device 9, on which a contact is held is. Furthermore, a butt part 4 is arranged on the armature, which is made of an insulating material.
  • the magnet system 2 together with the contacts is surrounded by a cap 5 in which a test pin 6 'is guided in a guide 13'.
  • This test pin 6 ' can be pressed against the inclined surface 7 of the abutment part 4, whereby the armature 3 can be pressed into its working position.
  • an actuator 8' is provided.
  • the actuating device 8 ' is designed as a key and has a handle 14, which is at the same time designed as an information part with clear labeling (e.g. "TEST") and has a correspondingly striking color. This ensures that an actuating device that is used stands out and that the risk that an actuating device that is used accidentally remains on a relay after the end of a test is avoided.
  • TEST information part with clear labeling
  • the guide 13 ' has in its outer area on the inside a backdrop 20, which is shown in the developed state in Figs. 2b to 2d and which projects into the interior of the guide 13'.
  • the backdrop 20 has two sections 21, 22 which are separated by two recesses 23 which are offset from one another by 180 ° in the exemplary embodiment shown. These recesses correspond radially from the key 8 'projecting pin 24 which are arranged in the region of the free end of the key 8'.
  • This end region of the key 8 ' has a diametrically extending slot 25, whereby this region can be compressed, as can be seen in Fig. 2a.
  • the slot 25 of the key 8 ' extends at an angle of 90 ° to the connecting line of the diametrically opposite pin 24 of the key.
  • the depth of the recesses 23 of the guide 13 ' is dimensioned such that the pin 24 of the key can be inserted into the recesses 23 without narrowing the slot 25. This position of the key 8 'is shown in Fig.2b.
  • the guide 13 ' has 90 ° offset from the recesses 23 arranged further recesses 26 which are closed in the region of their upper end by the link portions 21, 22 upwards.
  • the link portions 21, 22 in the area of these recesses perpendicular to the axis of the guide 13 'extending surfaces 27 to which connect obliquely against the axis of the guide 13' extending surfaces 28, 29, the surfaces 28 and 29 having an opposite slope exhibit.
  • the depth of these recesses 26, which serve as run-up surfaces, corresponds to that of Recesses 23.
  • Both the recesses 26 and 23 have rounded side edges 32 and 33.
  • the diameter of the guide 13 'below the backdrop 20 is such that it corresponds to the distance between the outer surfaces of the pin 24 of the key 8' with the slot 25 largely compressed.
  • the side walls of the pin 24 have a slight inclination, so that the pin 24 which has fallen into the recesses 26 can be unscrewed from these recesses 26 again by a corresponding effort when turning the key 8 '.
  • the test pin 6 ' has a guide portion 30' held in the guide 13 'which engages with a spring-like projection in a recess 26 and is held non-rotatably. At the end of this guide section 30 there is an eccentrically arranged pin 31 which bears against the butt part 4 of the armature 3. In normal operation, the force of the return spring 9 of the hinged armature 3 is sufficient to press the test pin 6 'over the inclined surface against which it rests when the armature falls.
  • the key 8 Due to the inclined surfaces 28, 29 of the backdrop 20, the key 8 'pushes further down as it rotates further and presses the test pin 6' against the abutment part 4 of the armature 3, whereby this is pressed against its working position.
  • the actuating device is also formed by a key 8 ⁇ . This has on its one end face a slot 40, which meshes with an oppositely shaped axial extension 41 of the test pin 6 'in the attached state.
  • This key 8 ⁇ has radially projecting pins 42, which in the inserted state of the key 8 ⁇ engage behind an inwardly directed flange 43 which is provided with a number of recesses 43 corresponding to the number of pins 42 'through which the key 8 ⁇ in the guide 13 ⁇ is insertable and rotatable in this.
  • the position when the key 8 ⁇ is inserted is shown in FIGS. 4a, 5a and 6a, a rotational position during rotation of the key 8 ⁇ in the direction of the working position in FIGS. 4b, 5b and 6b.
  • the test pin 6 ⁇ has a radially projecting pin 44 which slides along the link 45 arranged in the region of one end of the guide 13 ⁇ .
  • the backdrop 45 is formed by the lower end face of the substantially cylindrical guide 13 ⁇ against the The axis of the guide 13 ⁇ is inclined, as indicated by the broken line in FIG.
  • This guide 13 ⁇ also has a slot 47 into which a resilient tongue, which serves as a resilient stop 46, engages. This makes it possible to safely sense the achievement of the working position of the test pin 6 ⁇ and thus also the armature 3 ⁇ .
