Definitions

  • the invention relates to a push-button-operated overcurrent protection switch with the features of the preamble of claim 1.
  • a known overcurrent protection switch has a narrow housing, between the side walls (broad sides) of which two contact elements are held and a push button and a compression spring interacting with it are guided in a longitudinally displaceable manner.
  • the two ends of the contact elements which protrude from the housing are designed as parallel tongues lying next to one another.
  • the known switch is triggered via a bimetal.
  • the formation of the switch lock of the prior art switch is relatively complex and voluminous, so that it cannot be manufactured cheaply and in a small design.
  • the invention has for its object a switch with the features of the preamble of To minimize claim 1 so that it can be inserted and used in place of the flat fuse previously known, for example from DE-OS 31 15 435, in a flat fuse plug-in base without taking up much more space than the flat fuse.
  • This object is achieved by the characterizing features of claim 1.
  • the arrangement and design of the five switch components means that the switch lock can be accommodated in the smallest of spaces.
  • Multiple tasks are assigned to all switch components, for example the bimetal spring washer is not used. only as an active trigger element, but also as a locking element for the push-button partition, which in addition to its locking function ensures reliable mutual insulation of the open switch contacts.
  • the compression spring is responsible for the latching pressure as well as for moving the control button to the "off position".
  • the switch can be installed particularly easily and, if necessary, fully automatically if, according to claim 2, the housing consists of two identical housing half-shells lying parallel to one another and the contact elements consist of stamped and bent parts of identical design.
  • the switch assembly is completed and completed by simply inserting the switch parts into a (lower) housing half-shell and then fitting the second housing half-shell as a cover. The identity of the addressed parts simplifies their storage.
  • Claim 3 ensures that the bimetallic snap disk does not warp under the pressure of the compression spring driving the push button outwards.
  • the particularly wide bimetallic snap disc ensures a pronounced snap effect, which leads to a defined switching behavior of the simplest switch.
  • the formation and arrangement of the partition wall on the push button which is taught by claim 4, supports the push button guide and in particular ensures that the push button which is loaded on one side in the locking position on tilting does not get caught in its opening-off movement. Since the compression spring overlaps a guide pin which is arranged parallel to the partition, the overall height of the compression spring and push button assembly in the axial push button displacement direction is minimized, which leads to a reduction in the overall height of the switch in the insertion direction; as a result, the switch according to the invention is not very much higher than the conventional fuses.
  • a further reduction in the overall height and improvement of the guiding properties of the push button is achieved by claim 5, since the push button formally engages over the relatively wide bimetal snap disk in the pressed-in state.
  • Claims 6 and 7 provide a particularly good hold of the elements which are merely inserted into the housing guaranteed.
  • Claim 10 teaches an integrated in the housing holding shells training of additional holding elements, which ensures support of the protruding tabs that hold the switch essentially in the fuse clipboard.
  • Claim 11 ensures additional stiffening of the housing in the transverse direction and permanent determination of the distance between the two contact elements.
  • the overcurrent protection switch which can be actuated by a push button 1 (hereinafter briefly referred to as protection switch 2 ) has a housing 5 consisting of two parallel half shells 3, 4 made of insulating material, in which two contact elements 6, 7 are held and the push button 1 is guided together with a compression spring 8 in the longitudinal direction 9 of the housing 5.
  • the ends of the contact elements 6, 7 protruding from the underside 10 of the housing 5 are formed as parallel and equally adjacent plug tongues 11, 12.
  • the contact elements 6, 7 are designed as contact ends, with the one end of the bimetallic element designed as a bimetallic spring washer 15 being fastened with its fastening end 16 and the other end 14 carrying a contact nipple 17, which has a mating contact nipple 18 interacts as a switch contact.
  • the mating contact nipple 18 is carried by the swivel end 19 of the bimetallic spring washer 15.
  • both the two half-shells 3, 4 and the contact elements 6, 7 provided with the bends 22, 23 can be of identical design.
  • the bimetallic spring washer 15 is fastened with its fastening end 16 to the inner end 13 of the contact element 6 in such a way that in the non-excited state it presses in the direction of the arrow 27 with its mating contact nipple 18 on the contact nipple 17 and the contact path is thus closed.
  • the push button 1 is in the area of its interior End 28 is provided with a one-sided protruding, approximately de, plane of the parting line 26 dividing wall 29 which, when the bimetallic spring washer 15 is not energized, bears against the counter-contact nipple 18 of the bimetallic spring washer 15 from the bottom under pretension of the compression spring 8.
  • the partition 29 snaps under the pressure of the compression spring 8 between the opening contact nipples 17, 18 and ensures their safe electrical separation.
  • the bimetallic spring washer 15 Since the bimetallic spring washer 15 is exposed to the pressure of the compression spring 8 acting on it laterally when the circuit breaker 2 is switched on, for reasons of strength it has a width in the longitudinal direction 9 which corresponds approximately to its length of extension between the attachment end 16 and the pivot end 19.
  • the partition wall 29 is approximately L-shaped, a first L-leg 30 approximately parallel to a guide pin 31 immersed in the compression spring 8 and a second L-leg 32 approximately at right angles to it. The latter forms the partition 29.
  • the push button 1 is further provided eccentrically with a continuous groove 33 which extends into its actuating part protruding from the housing 5 and runs parallel to the plane of the parting line 26 and which overlaps the upper edge 34 of the bimetallic spring washer 15 facing the actuating button 1, at least in the switched-on state.
  • the half-shells 3, 4 of the housing 5 are provided both with insertion recesses 35 for the contact elements 6, 7 and with guide grooves 36 lying opposite one another in the longitudinal direction 9.
  • the compression spring 8 lies in one of the two guide grooves 36 and is guided by it during its longitudinal movement. With its end facing away from the push button 1, the compression spring 8 is supported on the platelet surface 51 facing the push button 1 of a transverse stiffening element 48 made of insulating material, which lies between the two contact elements 6, 7 and these with diagonally opposite recesses 49, 50 in the region of the turns 22, 23 overlaps and is spaced apart.
  • a lower housing section 37 encompasses the inserted upper ends of the tongues 11, 12 on each side and ensures a secure hold.
  • Holding pins 38 and corresponding counter-recesses 39 are arranged on the housing section 37 in such a way that when the identical half-shells 3, 4 are placed against one another in the final assembly position, the holding pins 38 dip into the counter-recesses 39. They reach through round holes 40 which are provided in the tongues 11, 12. On the narrow sides 41, 42 of the housing section 37, resilient hooks 43, 44 are attached, between the rear sides 45, 46 of which there is a distance 47 that allows the hooks to deflect.
  • retaining pins 52 and counter-recesses 53 are provided on the half-shells 3, 4 for mutual end fastening of the half-shells 3, 4 together.
