Definitions

  • the invention relates to a push-button-operated overcurrent protection switch and in particular to an on-board circuit breaker with manual release and bimetallic free release with the features specified in the preamble of claim 1.
  • overcurrent protection switches are known for example from DE-C 21 23 765 or EP-A 0 081 290.
  • the bimetallic element of the bimetallic release device is arranged essentially parallel to the narrow side wall of the switch housing running in the pressure direction (D).
  • the adjustment is carried out using an adjusting screw, which passes through a hole in this side wall and acts directly on the bimetal or on its connecting base.
  • connection lug and the area of a connecting piece adjoining the mating contact fixed to the housing to the mating contact fixed to the housing are held in a fitting and fixed manner in corresponding bearing recesses in the housing.
  • the bimetal is not used for adjustment, but the connector inside the housing Area is acted upon by an adjusting screw screwed into the side of the switch housing.
  • a cross-sectional reduction in the form of depressions in the lateral surfaces of the connector is provided between the fixing area on the housing and the application area by the adjusting screw.
  • an electrical overload switch is known from DE-U-88 06 964.8, in which the strip-shaped bimetal is fastened to a connecting piece, which is also held in a fitting and fixed manner in corresponding bearing gaps in the housing.
  • This connector has an extension which can be acted upon by an adjusting screw from the opposite side of the switch housing for adjusting the response value of the bimetal.
  • the invention is based on the object of further improving a push-button-operated overcurrent protection switch of the type mentioned with regard to the adjustability of the bimetal.
  • the connecting tab of the connecting piece for the second leg end of the bimetal has a constriction, which is formed by a slot penetrating the plate-shaped central section of the connecting piece transversely to the plate plane.
  • the connecting tab can be rotated around the constriction by means of an adjusting screw for adjusting the response value of the bimetal. Due to this construction, the tripping value of the bimetal can be adjusted in a particularly sensitive and exact manner by bracing the two bimetal legs against each other.
  • the narrowing further has the advantage that the heat generated by the bimetal self-heating for tripping flows less quickly from the bimetal into the adjacent conductor parts of the assembly. This means that the nominal tripping value is more reproducible and less scattered.
  • Claims 2 and 3 characterize advantageous designs of the slot and the mounting of the adjusting screw in the housing.
  • the slot can be produced particularly easily immediately when the connecting piece is punched, in the case of a realization by means of an arcuate punching.
  • the adjusting screw is held captively in the housing by its radially protruding rim, which is supported in a housing groove, on its head.
  • the bimetallic assembly is fixed even better in the housing by the extension of the terminal lug at its inner end and its precise, firm fit in a corresponding housing recess.
  • the characterizing part of claim 5 describes a bimetallic release device which has two bimetals.
  • a self-heated bimetal device can also be used for small nominal currents, which, in addition, does not provide any lower triggering forces in comparison with a one-piece bimetal. Due to the sandwich construction claimed, the entire bimetal device remains very compact and can be arranged and used essentially like a one-piece bimetal. The insulating layer between the two bimetals shields the latter from one another in such a way that the full current path is maintained through the total length of the two bimetals.
  • brace-like stiffeners are provided according to claim 8, which can be placed on said bimetal sections with the interposition of appropriate insulating layers.
  • the bimetal device of this type thus also has essentially unchanged mechanical properties.
  • Claims 9 and 10 characterize a so-called fail-safe for the switch. This is advantageously integrated in the connector of the bimetallic device.
  • the terminal lug, one or more bimetals, the connection piece, optionally provided with a fail-safe device, and the adjusting screw are combined to form a preassembled module which can be installed as a whole in the switch. This also has advantages in terms of automatic production when mounting the switch.
  • Claims 12 and 13 characterize an advantageous further development of the bimetallic assembly with which a rapid response of the bimetallic tripping device is achieved in the case of high currents, in particular in the event of a short circuit.
  • these two components can be positioned particularly close to one another without the risk of an electrical short circuit, so that a particularly high repulsion effect is achieved with a very short tripping time.
  • Fig. 1 the external view of the switch according to the invention is shown.
  • This has an approximately cuboidal housing made of insulating material, which is composed of two housing half-shells (1, 2), on the front narrow side wall (3) of which the push-button assembly (4) with its threaded neck (40) and the push-button (2) which is longitudinally displaceable in the direction of pressure (D) 41) is used.

Furthermore, a kinematic connecting element between the switching lock (7) and the bimetallic assembly (10) forming, frame-like release lever (12) and the adjustment cover (13) which can be snapped onto the lower narrow side wall (3 ') should be mentioned.
  • the centerpiece of the bimetallic assembly (10) is the bimetal (101), which is designed as a flat, U-shaped stamped and bent part and is attached with its one leg-free end (102) to the housing-internal extension (103) of the connecting lug (5).

  • the connecting piece (106) has an arcuate punching (108), in the center of which a threaded hole (109) is made.
  • the adjusting screw (110) can be screwed in from the bottom narrow side wall (3 ') by rotating the connecting piece (106) about the constriction (111) formed by the punched out (108) so that the two legs (112, 113) of the bimetal ( 101) can be braced against one another and the triggering value of the bimetal (101) can thus be adjusted.
  • the base (114) of the U-shaped bimetal (101) represents its deflecting end, its deflecting movement by means of the transfer slide (14) arranged in the housing transversely to the direction of pressure (D) below the push-button assembly (4) and the release lever (12) connected to the switch lock (7) in the sense the triggering of which is transmitted.
  • the switch is switched on and off manually by means of the push button (41) of the push button assembly (4), which is explained in more detail below with reference to FIGS. 3-6.
  • the essentially cylindrical push button (41) made of insulating material is provided with a blind hole-like bearing recess (43) which is open towards the interior of the housing and extends in the pressure direction (D) and with which it is additionally guided on a guide part anchored in the housing in the pressure direction (D) is.
  • the guide part is jointly formed by a cap-shaped, made of insulating counterbearing shaped part (44) for the helical spring-like push-button spring (46) clamped between it and the actuating side bottom (45) of the bearing recess (43) and the U-shaped supporting part in the longitudinal section parallel to the pressure direction ( 47) formed.

Due to their design, the support (47) and counterbearing molded part (44) in turn form a guide (53) running in the pressure direction (D) for a support lever (15) which extends essentially in the pressure direction (D) and with its push-button side End (16) via a rotary slide Articulated connection is connected to the inner end of the push button (41).
  • This articulated connection is created by the axis (55) held on two lateral projections (54) of the push button (41) through the link-like elongated hole (17) in the push button end (16) of the support lever (15).
  • the elongated hole (17) is of an angular shape, the leg (18) pointing counter to the pressure direction (D) parallel to this direction and the leg (19) pointing in the pressure direction (D) pointing in an acute direction, counter to the locking engagement direction (20) Angle (W) run.
  • the support lever (15) has a latching projection (21) on the side next to the elongated hole (17) which, due to the displaceability of the support lever (15) in the pressure direction (D) and its pivotability transversely to this direction, engages with the latching recess (56) in one of the U-legs (48, 49) of the support part (47) can be brought.

If the push button is actuated, the axis (55) runs in the leg (18) of the elongated hole (17) parallel to the direction of pressure until it reaches the lower side edge of the elongated hole leg, which runs obliquely to this direction (19) hits. From this position, the support lever is moved in the pressure direction (D) and at the same time applied transversely to it.
