Definitions

  • the present invention relates to an electrical switch according to the preamble of claim 1 and to the use thereof.
  • the present invention has for its object to provide a switch, the actuator can be acted upon from a variety of different directions to inevitably perform the switching function. According to the invention, this object is achieved by the characterizing features of claim 1.
  • a switch according to the invention in a protective device for machines according to the characterizing part of claim 9.
  • the rod is arranged, for example, at a short distance in front of the inlet nip of a pair of rollers of a printing press, only a slight displacement of the rod is required to interrupt the circuit.
  • a finger between a roller and the When the rod is pulled the displacement of the rod on the finger translates in proportion to the distance from the switch, so that it practically interrupts the circuit and switches off the machine.
  • the protective device is designed in accordance with claim 10, the above-mentioned translation effect occurs at every point on the rod, so that the protective device can be implemented with practically any desired sensitivity.
  • a housing jacket 3 with an opening 4 is screwed onto a rotationally symmetrical base body 1 with an external thread 2.
  • Base body 1 and housing jacket 3 consist of an electrically insulating material.
  • a contact pin 5 sits axially in the base body 1 and can be connected to a circuit at 6.
  • the base body l forms a flat support 7, which is surmounted by the free end 8 of the contact pin 5.
  • the housing shell 3 is provided with a cylindrical inner surface 9 within which a disk-shaped part 10 of the movable contact 11 is mounted.
  • the peripheral surface of the disk-shaped part l0 is rounded in cross section, the radius R being at least approximately equal in the diameter of the part l0.
  • the part l0 is also with little play in the housing shell 3, so that it can be pivoted in the manner shown in Fig. 2. Furthermore, it has a circular edge 12 on the side facing the support 7, which in turn lies in a plane parallel to the support 7.
  • An actuating cam l3 adjoins the disk-shaped part l0 of the movable contact 11 axially, the outer end of which is rounded. The lateral distance between the actuating cam l3 to the opening 4 is so large that the disk-shaped part l0 can be pivoted in the manner shown in FIG. 2, in which it is lifted off the end 8 of the contact pin 5.
  • a foam rubber ring l4 is inserted, which is prestressed when the housing cover 3 is screwed onto the base body l and presses the disc-shaped part l0 against the end 8 of the contact pin 5, which acts as a spacer, so that there is a slight distance l5 of a few tenths of a millimeter between the edge l2 and the support 7 and a current flow from the fixed to the movable contact 6 or 11 is possible.
  • the fixed contact 5 and the movable contact ll consist of electrically conductive material.
  • each lateral force component on the cam l3 causes the disk-shaped part l0 to pivot or tilt according to FIG. 2, as a result of which the edge l2 at one point with the support 7 of the insulating base body 1 comes to rest, as a result of which the part 10 stands out from the support 7 in such a way that the contact with the fixed contact 5 is canceled (and thus the circuit is interrupted).
  • the sensitivity of the switch can be within wide limits be varied.
  • FIGS. 1 and 2 show a use of the switch according to FIGS. 1 and 2 in a safety device on a printing press.
  • Two switches are attached to the cheeks l6 of the machine stand in a symmetrical arrangement. These are arranged in a circuit 17 interrupting the machine drive.
  • the actuating cams l3 of the two switches are electrically conductively connected to one another by a tube l8 which is loosely pushed over them.
  • the tube is arranged as close as possible to the inlet nip between printing unit rollers 19 (the upper one is not shown) and in a parallel alignment to these.
  • the elastic preload of the foam rubber rings l4 must be so great that, despite the weight of the tube l8, the fixed and movable contacts 5 and 11 touch, or the edge l2 and the support 7 are aligned in parallel and thereby close the circuit l7 . If, for example, an operator reaches with a finger or hand at 20 between the tube l8 and one of the two pressure rollers l9 forming the inlet gap, the tube l8 is slightly pressed away from the pressure roller l9, with the tube ends pivoting the actuating cams l3.
  • a housing body 20 is provided with a blind hole 2l, which forms a cylindrical inner surface 9 ⁇ .
  • the movable contact ll ⁇ is arranged, the disc-shaped part l0 ⁇ front has an electrically conductive layer.
  • the laterally raised edges of part l0 ⁇ are rounded, the radius of curvature R ⁇ being at least approximately equal to its diameter.
  • the 7 ⁇ of the support Blind hole 2l facing edge l2 ⁇ of part l0 ⁇ also lies in one plane.
  • the movable contact ll ⁇ has on the side facing away from the edge l2 ⁇ an annular shoulder which is in contact with a prestressed foam rubber ring l4 ⁇ , which in turn is supported against an annular disk 23 held by a snap ring 22.
  • the snap ring 22 is seated in an annular groove open in the cylindrical inner surface.
  • the movable contact ll ⁇ extends through the foam rubber ring l4 ⁇ , the washer 23 and the snap ring 22 to the outside and forms a socket-like actuating cam 24 with a circular access opening, which is delimited by an annular rib 25 with a rounded cross section. If (as in the application example according to FIG. 3) a tube l8 ⁇ with one end is pushed into the actuating cam 24, the movable contact ll ⁇ can be pivoted on all sides, the foam rubber ring l4 ⁇ generating a restoring force that wants to align the edge l2 ⁇ parallel to the support 7 ⁇ .
  • the support 7 ⁇ of the blind hole 2l is axially protruded from the end 8 ⁇ of the fixed contact pin 5 ⁇ , which holds the non-pivoted, disc-shaped part l0 ⁇ at a distance l5 ⁇ from the plane 7 ⁇ when it is pressed under the uniform pressure of the foam rubber ring l4 ⁇ against the contact pin 5 ⁇ .
  • the outer end of the contact pin 5 ⁇ is used to connect an electrical conductor.
  • a second bore 26 is in the bottom of the housing body 20 parallel to the fixed contact 5 ⁇ a pin-shaped conductor 27 axially displaceable therein.
  • the conductor 27 is pressed by a coil spring 28 prestressed under pressure beyond the plane 7 ⁇ into a constant contact with the conductive layer of the part l0 ⁇ .
  • the outer end of the conductor 27 is used to connect an electrical line, the conductor connections mentioned being covered by a removable protective hood 29 which is detachably connected to the housing body 20.
  • the movable contact ll ⁇ is pivoted by a pressure on the tube l8 ⁇ , the conductor 27 always remains in contact with the movable contact ll ⁇ , which is lifted by tilting on the support 7 ⁇ from the tip 8 ⁇ of the fixed contact pin 5 ⁇ .
  • the foam rubber ring l4 ⁇ presses the disk-shaped part l0 ⁇ and the movable contact pin 27 back until it touches the contact pin 5 ⁇ again and closes the circuit.
  • the foam rubber ring l4 or l4 ⁇ can be replaced by a coil spring.
  • the contact pin 5 ' is surrounded by an insulator 35, on which a contact ring 36 is pushed axially and with play and is pressed against a stop 38 by a spring 37.
  • the springs 3l and 37 can be connected to electrical circuits. If a force is applied to the cam l3 ⁇ , the ring disk 30 is pivoted or tilted away from the contact disk 33 and the circuit 39 is interrupted. When this force application moves the movable contact ll ⁇ axially until its washer 30 touches the contact ring 36, the circuit 40 which has been interrupted until then is closed.
  • the conductor 27 can be arranged in a housing-fixed manner in an annular groove surrounding the contact pin 7.
  • An electrically conductive, spring-loaded coil spring made of beryllium bronze is arranged in this annular groove. This is in every position of the movable contact ll ⁇ with its conductive layer on the one hand and the conductor 27 on the other in contact.
  • the preload of this electrically conductive spring must, however, be smaller than that of the foam rubber ring l4 ⁇ or a spring instead of this.
  • the movable contact 11 has a circular disk 29 with a rounded, peripheral surface. With this, the actuating cam l3 ⁇ is firmly connected. Both are made of insulating material. It also has an electrically conductive washer 30, which is always held in contact with the washer 29 by a helical spring 3l.
  • the Ring disk 30 is provided with a central bore 32.
  • the stationary contact pin 5 ⁇ protrudes through the bore 32 and is provided at the free end with a contact disk 33. This lies in a blind hole 34 in the disk 29 and has a larger diameter than the bore 32.
