Definitions
- Miniature circuit breakers are overcurrent circuit breakers with a first and a second tripping device that operate on a
- Switch lock act.
- An electromagnetic release device acts as a quick release in the event of a short circuit.
- a thermal bimetallic tripping device switches off in the event of permanent overloads if the affected line heats up excessively.
- the switch lock can also be operated by means of a manually operated switching knob, which means that the respective circuit breaker can also be used to interrupt a circuit.
- Switch lock are rotatably mounted on an axis.
- a series product such as a circuit breaker is subject to market-related, cost-restrictive requirements, which have a significant impact on the number of installed components.
- the circuit breaker of the previously listed has a number of device components which adversely affects these specifications.
- a partially reduced switch lock of a circuit breaker is known from DE 1 904 731.
- This key switch has a structural unit which is composed essentially of a movable contact arm, a release lever and a pawl.
- the movable contact arm is mounted on an axis.
- the switch lock has a plastic part in at least one section, but this must be made of a particularly durable and therefore expensive material due to the proximity to the contact point.
- the switching device is provided with a housing and with a switch lock
- the switching lock has a three-part assembly with a release lever, a pawl and a movable contact arm, - wherein the assembly is essentially formed from a metallic material, and the end of the movable contact arm forms a joint with the pawl by means of a connecting element,
- movable contact arm and the release lever are rotatably mounted on a housing-fixed deflection axis
- a spring supporting the latching of the switching lock comprises the joint at a first end, bears against the deflection axis and acts on the release lever at a second end, and - forces acting on the assembly and occurring between the components of the assembly essentially in one plane run.
- the inexpensive construction of a switch lock that can be achieved by the invention has a cost-reducing effect on the manufacture of a switching device.
- This is given in particular by the three-part structural unit of the switch lock, which is made from simple, metallic, possibly material-uniform, stamped and bent parts.
- the uniaxial bearing of the contact arm and the release lever contributes to the inexpensive manufacture.
- the spring which favors the balance of forces and the rear latching is arranged or designed in such a way that it can follow the movement sequence of the structural unit on the one hand or is functional with a low preload on the other hand.
- a further component for compensating a tilting moment that occurs is not necessary since forces acting on the structural unit or occurring between the components of the structural unit are effective in only one plane.
- FIG. 1 shows a switching device with a switch lock in the off position in a side view
- FIG. 2 shows a switching device according to FIG. 1 in a front view
- FIG. 3 shows a switching device according to FIG. 1 in a top view.
- the 1 shows a switching device 1 with a housing 2 and a switch lock 3 in the so-called off position AS.
- the key switch 3 has a release lever 4, a pawl 5, a movable contact arm 6 and a deflection axis 7 fixed to the housing.
- the components switch lock 3, release lever 4 and pawl 5 are made of a metallic material, in particular steel, brass, copper, bronze and / or brass, and of stamped and bent parts.
- the release lever 4 and the pawl 5 grip around the contact arm 6 and are connected to the contact arm 6 by the inserted deflection axis 7 and the bolt 9 connected.
- the contact arm 6 has an approximately mirror-inverted S-shape and is provided approximately in the middle on its component length with a cutout 8 in which the deflection axis 7 is arranged.
- the recess 8 can be both open and closed and is essentially directed towards the release lever 4 with respect to the component width of the contact arm 6.
- the recess 8 has an oversize in relation to the deflection axis 7, which makes assembly of the device components easier.
- the recess 8 in connection with the deflection axis 7 only serves to hold the device components together.
- the deflection axis 7 is largely freely arranged in the recess 8 and, if necessary, fulfills a limiting or deflecting function as a stop.
- the receiving element 11 can be designed both as a molded part of the housing 2 and as a separate housing part.
- the separate housing part can be arranged so that it can be moved around in the housing 2, so that there are a multitude of design options.
- the pawl 5 is connected to a bracket 13, which in turn is in operative connection with a toggle roller 14.
- the housing 2, which is possibly made of insulating material, can consist of two housing shells, each with a receiving element 11, the bolt 9 being guided on both sides.
- the bolt 9 is encompassed at its first end 16 by a spring 15 which supports the latching of the switching lock 3.
- the back latch ensures in the off position AS that the key switch 3 assumes a defined switching state.
- the spring 15 bears against the deflection axis 7 and acts with its second end 17 on an extension 18 of the release lever 7.
- the spring 15 acts in the on position ES as vibration or vibration protection against unwanted unlatching.
- the contact arm 6 has an engagement opening 19 for a tension spring 20 engaging therein between the recess 8 and the bolt 9.
- the tension spring 20 is also received in a receiving opening 21 of a holder 22 and is preloaded.
- the bracket 22 can be mounted or adjusted in a first angular range ⁇ such that different contact spring positions can advantageously be assigned different contact forces, as a result of which definable switching device types can be determined.
- a first contact piece 24 is arranged approximately at the same height as a second contact piece 25.
- the second contact piece 25 is placed on a fixed contact carrier 26, which is part of a structural unit that is not described in more detail here.
- the receiving element 11, the holder 22 and the fixed contact carrier 26 are not shown.
- the triggering devices of electromagnetic and thermal type mentioned at the outset in each case trigger a first force KE or a second force KT, which act on the trigger lever 4 and reset the switching mechanism 3 and thus the toggle roller 14 into the off position AS.
