Definitions

  • the invention relates to an overcurrent protection switch with the features of the preamble of claim 1.
  • a mechanism for self-switch namely overcurrent protection switch is known, the main features of which are as follows:
  • an elongated contact bridge is pivotally arranged in the switch level, which can be controlled manually by means of a handle, namely a rocker arm, and cooperates with a fixed contact to close the current path.
  • the contact bridge In the contact opening direction, the contact bridge is acted upon by a spring which acts on the rocker arm in such a way that its spring preload is increased when the rocker arm is in the switched-on position.
  • the end of the contact bridge remote from the contact is latched by a ratchet lever which interacts with a release device, namely a magnetic release, the contact bridge is supported approximately in the middle in the manner of a two-armed lever on a rotary bearing which is arranged on a contact bridge holder.
  • the pawl lever If, in the event of a short circuit, the pawl lever is actuated by the triggering device, it releases the end of the contact bridge remote from the contact, so that it can suddenly swivel away from the fixed contact under the tension of the spring. In the event of a restart (by moving the rocker arm first to the off position and then turning it back to the on position), the contact end of the contact bridge is slowly moved against the fixed contact, which disadvantageously results in creeping contact. The contact pressure is exerted by the resiliently remote end of the contact bridge, which makes the contact bridge relatively complex overall.
  • the invention has for its object to simplify the design of an overcurrent protection switch, while maintaining the sudden, spring-assisted switch-off, a torque switch is possible and in particular the number of necessary spring elements should be reduced.
  • the contact bridge pivot As the essence of the invention, it is considered, in the case of manual switching on and off, to make the contact bridge pivot as a one-armed lever around the non-contact end, which is supported by the latch lever, the only spring acting on the contact bridge acting in the contact direction and in In the event of an emergency triggering, the effect of the same contact spring can be used to break the contact, which is done in that in the event of an emergency triggering, the contact bridge support, ie the fulcrum of the contact bridge, is moved to its central region. It is therefore essential to the invention that the only contact spring between the two possible pivot points, namely the at the far end for manual switching on and off and the central pivot bearing on the contact bridge.
  • the contact spring is effective in contact-opening or contact-closing while maintaining its pulling direction. In connection with the articulation beyond dead center with subsequent freewheeling into one or the other position by the spring action, an abrupt contact closure (moment engagement) of the contact is achieved.
  • Claims 2,3 and 3a relate to different types of design of the central pivot bearing, namely - in a manner known per se - via a contact bridge holder or by means of one or more housing projections which act on the contact bridge in the center or by means of the free end of the pressure plunger, which is the central one Pivot bearing forms (3a).
  • guide means provided in the housing and allowing the release movement are required, which can be designed according to claim 4 as housing grooves with side projections guided therein at the end of the contact bridge remote from the contact, thereby advantageously providing space for other switching element elements in the area of the contact bridge center, for example the pressure ram is created.
  • lateral guide grooves are arranged in the central region of the contact bridge, as a result of which in particular the end remote from the contact can pivot smoothly and uninhibitedly into the switch-off position in the event of an emergency release.
  • the housing-fixed stop effective for arc quenching forms a counterbearing when the switching lock is tensioned solely by pressure exerted by the pressure ram in accordance with the characterizing feature of claim 7.
  • the locking stop according to claim 13 serves to ensure a momentary release in the event of an overcurrent.
  • the ratchet lever can therefore not be deflected according to the deflection of the bimetal by the spring acting on it in the contact opening direction. Rather, the locking stop ensures that the unlocking of the ratchet lever takes place suddenly only after the desired deflection of the bimetal has been reached in the event of an overcurrent. This is achieved in a particularly space-saving manner according to the characterizing feature of claim 14.
  • the pressure plunger and the control link articulated with it form a toggle lever, the dead center position of which is the extended position of the toggle lever.
  • the rocker arm only has the function of moving this toggle lever over its extended position against the pressure of the contact spring. Then the control arm is swiveled into its respective swivel end position automatically and independently of the swivel speed of the rocker arm only under the pressure of the contact spring.
  • the overcurrent protection switch contains in the switch housing 1 the contact spring 2, the contact bridge 4 interacting with the fixed contact 3, the contact bridge holder 5, the latch lever 6, the strip-shaped bimetal 7 and the rocker arm 8 rotatably mounted on the housing 1.
  • the passage of current through the switch between the two connecting terminals 9, 10 takes place via the bimetal 7, the connecting cable 12, the contact rail 11, the connecting cable 12a, the contact bridge 4 and the fixed contact 3, which in turn via the fuse 26 with its two connecting contacts 27, 28 and the rail 25 with the connecting terminal 10 is in an electrically conductive connection.
  • the contact bridge 4 is designed as a two-armed lever. As a result, it has the contact arm 13 close to the contact and the holding arm 14 remote from the contact.
  • the contact bridge bearing is marked with 15.
  • the non-contact holding arm 14 of the contact bridge 4 is acted upon by the contact spring 2 in the contact opening direction.
  • the contact spring 2 is a tension spring whose distal end 16 is fastened to the switch housing 1 in the vicinity of the rocker arm 8. Through the contact spring 2, the contact bridge 4 is pulled with the end of its holding arm 14 against a swivel limiting stop 17 which is rotatably mounted on the latch lever 6 about an axis perpendicular to the longitudinal plane of the switch.
  • the pawl lever 6 is mounted on the housing 1 in the area of its bearing end 18 in the switch plane about the axis 19.
  • the axis 19 lies between the contact bridge 4 and the rocker arm 8.
  • the pivoting end 20 of the latch lever 6 can be deflected by the bimetal 7 from its normal position shown in FIGS. 1, 2 and 4 ff.
  • the latch lever (6) Into the pivoted position shown in FIG. 3.
  • the latch lever (6) also contains a fixed stop 22 protruding into the path of the further contact opening in the contact opening direction 21 of the holding arm 14 of the contact bridge 4.
  • the contact bridge holder 5 is in with its end facing away from the contact bridge bearing 15
  • the switch level is pivotally mounted on the housing 1 and is acted upon by a pressure plunger 23 which is effective against the pulling direction of the contact spring 2 and can be transferred from the rocker arm 8 via a dead center with a subsequent automatic movement sequence.
  • the contact bridge 4, more precisely the contact arm 13, and the contact bridge holder 5 are connected to one another in the manner of the handlebars of a toggle lever, the knee joint formed by the contact bridge bearing 15 through the pressure plunger 23 into its extended position (FIG. 7) and through the contact spring 2 from the The stretched position can be converted into its kinked position (FIG. 5).
  • the bearing axis 29 of the contact bridge holder 5 overlaps approximately with the axis of rotation 24 of the swivel limit stop 17.
  • the latch lever 6, which in turn is aligned approximately parallel to the bimetal 7, extends approximately at right angles to the longitudinal direction of the contact bridge 4 or to the contact bridge holder 5.
  • the pivot axis 19 of the pawl lever 6 is arranged at its end facing the rocker arm 8.
  • the bearing axis 29 of the contact bridge holder 5 lies between the axis 19 and the pivot end 20 of the latch lever 6.
  • the pivot limiting stop 17 is only effective in the contact opening direction 21 against the holding arm 14 of the contact bridge 4 and thereby limits its pivoting path in the contact opening direction 21.
  • the pivot limiting stop 17 can be pivoted away from its pivot limiting position mounted on the pawl lever 6 and acted upon by a return spring 30 turning it back into its swivel limiting position such that, when the pawl lever 6 is in the normal position, it stands as a stop in the swivel path of the holding arm 14 of the contact bridge 4 pivoted in the contact opening direction 21 and when the contact bridge 4 swings back out of its system is deflected from the stop position on the fixed stop 22 by the holding arm 14.
  • the bimetal 7 runs approximately parallel to the ratchet lever 6 next to this. Its deflecting end 38, which lies approximately next to the pivoting end 20 of the ratchet lever 6, acts upon the arm 39 of the angle lever 40 pivotably mounted on the housing 1 in the switch plane, the other arm 41 of which acts on the locking stop 36 in the unlocking direction opposite the direction of the arrow 37 to its spring action, whereby the locking stop when it reaches its unlocking position (FIG. 3) releases the pivoting of the pawl lever 6 under the pressure of the unlocking spring 35 in the unlocking direction 34. In its unlocked position, the free end 20 of the ratchet lever 6 overlaps the V-shaped, sector-shaped recess 42 of the locking stop 36 and plunges into this recess 42.
  • ver plunger 23 is pivotally articulated between two pivot end positions (Fig. 1.4 on the one hand and Fig. 6 on the other hand) in the switch plane at the end 43 of a control arm pivotally mounted on the switch housing 1.
  • the two pivot end positions are on either side of a dead center position closest to the contact bridge holder 5.
  • the control arm is as about the axis 44 rotatably mounted disc 45 which rotatably supports the pressure ram 23 with its rocker arm end 46 at its periphery (end 43).
  • the rocker arm 8 is pivotally mounted about the axis 44.
  • the control arm formed by the disk 45 can be moved over its bottom dead center position by actuating the rocker arm 8, after which it swings automatically under the pressure of the contact spring 2 into its respective pivot end position (FIGS. 1.4 on the one hand and FIG. 6 on the other hand).
  • the bearing sleeve 47 of the rocker arm 8 surrounding the disc 45 is provided in the region of the articulation of the control arm (disc 45) with a cutout 58, the length of which points in the circumferential direction approximately the pivoting path of the control arm bearing (end 46 of the pressure tappet 23) between its dead center position and its pivoting end positions corresponds.
  • the pressure plunger 23 runs approximately parallel to the ratchet lever 6 and lies with its free end 48 against the upper edge 49 of the contact bridge holder 5.
  • the free end 48 of the pressure ram 23 is rounded off as a rolling track. It lies in the space between the bearing end 18 of the latch lever 6 and the housing wall 50 flanking the fuse 26 with lateral mobility.
  • the contact bridge carrier 5 contains two cheeks 51 running parallel to one another in the switch plane, which are firmly connected to one another and between which the contact bridge 4 is arranged.
  • the ratchet lever 6 is also arranged between the cheeks 51.
  • the bearing axis of the contact bridge 4 is formed by pins 52 formed on both sides of the contact bridge 4 and which lie in bearing eyes 53 inserted into the cheeks 51.
  • the contact bridge 4 is formed by a metal stamped part.
  • the pins 52 consist laterally of the contact bridge 4, with the contact bridge 4 one-piece sheet metal rag.
  • the bearing eyes 53 each have a convex side wall 54 on the contact spring side as a counter bearing for the pivoting movement of the contact bridge 4.
  • the pawl lever 6 is a sheet metal part bent in a U-shaped cross section, between the U-webs 55 of which the holding arm 14 of the contact bridge 4 projects.
  • the pivot limiting stop 17 is designed as a shaft rotatably mounted in the cheeks 61 of the ratchet lever 6, the cross-section of which is approximately semicircular in the stop region lying between the U-legs.
  • the holding arm 14 of the contact bridge 4 rests with its end on the lower circumferential region 56 of the semicircular cross section of the pivoting limit stop 17 that is adjacent to the semicircular diameter 55 and which is caused by its rotation by rotating the shaft or pivoting away the pawl lever 6 the holding arm 14 can be brought out.
  • the bimetal 7 or the locking stop 36 can also be deflected in a known manner by means of a magnetic release device designated overall by 57.
  • the deflecting end 38 of the bimetal 7 is pivoted counterclockwise by its heating or by the magnetic release device 57 around its upper clamping end.
  • the deflecting end 38 strikes against the arm 39 of the angle lever 40 and pivots the angle lever 40 clockwise about its axis.
  • the other arm 41 of the angle lever 40 rotates the locking stop 36 counterclockwise.
  • its recess 42 coincides with the pivoting end 20 of the ratchet lever 6.
  • the unlocking spring 35 presses the pivoting end 20 of the ratchet lever 6 into the recess 42, whereby the pawl lever 6 pivots counterclockwise about its bearing axis 29.
  • the locking stop 36 pivots under the influence of it restoring spring in the direction of arrow 37 to the same extent back to its starting position (Fig. 1,4 and 6).
  • the recess 42 of the locking stop 36 overlaps with the pivot path of the pivot end 20 of the ratchet lever 6 with the result that now when the tensile force acting on the holding arm 14 of the contact bridge decreases on the part of the contact spring 2 the ratchet lever 6 no longer under the then dominant Pressure of the unlocking spring 35 can pivot counterclockwise back into the deflection position shown in FIG. 3.
  • the rocker arm 8 was not actuated during the above-described movements within the switch.
  • the switch assumes the limit switch position shown in FIG. 4.
  • the rocker arm 8 In order to be able to restart, the rocker arm 8 must first be pivoted clockwise about the axis 44.
  • the disk 45 is rotated with the same movement. This means that the toggle lever formed by the disk 45 and the pressure tappet 23 is pushed into its extended position. With this transfer of the toggle lever formed into its extended position, the pressure ram 23 presses with its free end 48 the upper edge 49 of the contact bridge holder 5 downward. This pivots counterclockwise about its bearing axis 29 and moves the contact bridge bearing 15 downward.
  • the movement of the contact bridge bearing 15 causes a downward pivoting of the holding arm 14 of the contact bridge 4 in the clockwise direction, ie an extension of the through Contact arm 13 of the contact bridge 4 and the contact bridge holder 5 formed toggle lever.
  • the end of the holding arm 14 of the contact bridge 4 comes out of contact with the fixed stop 22 of the rocker arm 6 and strikes further pivoting clockwise against the surface of the pivot limiting stop 17 corresponding to the semicircular diameter 55. This does not provide any resistance to the further pivoting of the holding arm 14 of the contact bridge clockwise counter, because the pivot limit stop 17 pivots counterclockwise against the restoring force emanating from the return spring 30.
  • the end of the holding arm 14 of the contact spring sweeps past the semicircular diameter 55 of the swivel limiting stop 17. As soon as the holding arm 14 has passed the pivot limit stop 17, it is pivoted back in the clockwise direction into its starting position shown in the figures under the restoring force emanating from the return spring 30. If the toggle lever formed by the disk 45 and the pressure tappet 23 passes through its extended or dead center position by pivoting the rocker arm 8 further, the tension of the contact spring 2 has reached its maximum. As soon as the aforementioned stretching or dead center position has been exceeded, the pressure exerted by the contact spring 2 becomes fully effective in the sense of the knee joint of the toggle lever formed by the disk 45 and the pressure plunger 23 being bent again.
  • the disc 45 pivots clockwise through the free space of the cutout 58 of the bearing sleeve 47 of the rocker arm 8 until the plunger 23 laterally abuts the housing wall 50 and thus puts an end to the pivoting of the disc 45.
  • the plunger 23 then assumes the position shown in FIG. 6, regardless of whether the rocker arm 8 is already in its pivoted-out end position shown in FIG. 6 is located or held in that intermediate position in which the toggle lever formed by the disk 45 and the pressure ram 23 has been pushed through its extended or dead center position.
  • the contact spring 2 consequently relaxes and pulls the holding arm 14 of the contact spring 4 against the pivot limiting stop 17, which has been pivoted into the pivoting path of the holding arm 14 by its return spring 30, with the result that the further pivoting of the contact bridge 4 relative to the contact bridge holder 5 is blocked is.
  • the switch is in the switch-on position (FIG. 6).
  • the rocker arm 8 is pivoted counterclockwise.
  • the rear edge 60 of the bearing sleeve 47 moved forward during this pivoting movement presses the end 46 of the pressure ram 23 in front of it.
  • the toggle lever formed by disk 45 and pressure tappet 23 is pushed through its extended or dead center position again, the end of the holding arm 14 of the contact bridge 4 detaching from contact with the pivoting limit stop 17 by the contact bridge 4 being pivoted slightly clockwise relative to the contact bridge holder 5, that is, by both parts formed knee lever is slightly bent.

  • FIG. 14 represents a "mixed solution" of the two previously described exemplary embodiments. This is because use is made of the groove guide of the second exemplary embodiment according to FIGS. 9 to 13, the housing grooves 274 arranged in the switch housing 201 with associated side projections 275 in the middle region of the contact bridge 204 are relocated, but the contact lever latching with the latch lever 206 is used at the end remote from the contact (holding arm 214), as is shown in the first exemplary embodiment according to FIGS. 1 to 8.
