Description

The invention relates to a circuit breaker in which the contact system and that which can be calibrated per se Trigger system are assembled in a modular manner. In known circuit breakers, the individual Building blocks, d. H. the components of the switch each have a unit that can be produced by themselves; but they have the disadvantage that, when assembled to form the complete circuit breaker, they partially overlap. These modules are also designed so that their functionally active parts through Walls are covered or are on the side of the module that the mounting plate, on which all components of the circuit breaker are built, facing. With some switches the items are also arranged one above the other. Parts covered in this way are neither freely accessible still visible. It is true that one can assemble such a system from building block-like components Place the circuit breaker in a protective housing covering the entire switch. The assembly of a such a switch is very difficult. This is particularly effective when it is is about having to replace individual parts. It is impossible to observe the functionally active parts. For accommodating the circuit breaker in an insulating housing in which all components are mounted on or in a tightly enclosing insulating housing base plate, can do not use this circuit-breaker version.

The invention overcomes these disadvantages. According to the invention, such a circuit breaker is constructed in such a way that that the essential components of the switch with electrical and mechanical functions (such as the contact system, Tripping system, switch lock), viewed in one direction of expansion of the switch housing, are strung together without mutual overlap so that each component can be assembled or individually is interchangeable. This has the advantage of simple assembly, especially when it comes to replacements. the Components are observable, i. that is, they can be easily controlled. It is still a crowded one Construction possible. The entire circuit breaker takes up much less space than known ones Devices. The advantages of the invention also come into play when the components of the switch are not mounted on or in a tightly enclosing insulating housing base plate, but if another structure is chosen.

It is essential for the invention that the components from the front of the base plate or one Mounting plate are visible and freely accessible. Further features of the invention are evident from Circuit breaker in which the contact system and the tripping system that can be calibrated

are assembled in a modular manner

Description of an embodiment and also from the claims.

In the drawing, an embodiment of the view and partially in section is shown schematically. Therein, 1 denotes the base plate of an insulating housing, on or in which the components of the circuit breaker are mounted. The base plate is made, as is customary with insulating material structures is, from a bottom wall and side walls and chambers to accommodate the individual components. It forms an envelope that tightly encloses these components. The device is covered by an insulating material cap indicated in FIG. 2, which is in the contact system of the circuit breaker opposite part is designed as an arc extinguishing chamber. The cap can be used with those parts with which it covers components of the circuit breaker that are expediently observed from one made of transparent material.

The circuit breaker consists of the following components:

1. the contact system with switch lock,

2. the release system.

The contact system consists of the fixed contacts 2, the movable contacts 3 and the moving contacts bearing switching shaft 4. The switching shaft 4 is on a switch lock 5 on the one hand

a switching lever 6, on the other hand coupled to the trigger member 7 via the rod 10.

The release element 7 contains electromagnetic quick release and bimetal release. The modular Structure of the circuit breaker itself is not the subject of the invention.

The fixed contacts 2 of the contact system with the terminal screws 2 ¹ for connecting external lines are mounted in chambers of the insulating base plate 1 and are fixed here by screw bolts or the like. From the switching drum 4, which is made of insulating material, rail-like contact pieces emerge, to each of which a flexible band 8 is screwed. ^{Rail-like contact pieces 7 1} and 7 ² extend on both sides of the release element 7, of which the contact ^{piece 7 2} , corresponding to the fixed contacts 2, is mounted in chambers of the insulating base plate 1 and forms the terminal piece for connecting external lines. It is therefore designed in such a way that the lines (see Fig. 2), which are designed as rail pieces and optionally penetrate the release system as a loop or winding, extend on the one hand to the outlets of the insulating housing and the terminal pieces for connecting external lines and on the other hand, contact pieces form, which protrude over the release system, extend in the direction of the contact system and are extended by flexible line pieces 8, which can also be ^{screwed to exposed contact pieces 4 1 of} the contact system. The release system 7 is fastened by means of eyes 9 which extend beyond the release system or are accessible through openings in the insulating housing of the release system.

All components of the circuit breaker and the fastening means of these components are of the Front side of the insulating base plate 1 is accessible and visible. You can do it independently can be assembled and replaced individually.

PATENT CLAIMS: 40 1. Circuit breaker, in which the contact system and the tripping system that can be calibrated per se are wholly or partly assembled in a modular manner and mounted in an insulating housing base plate that tightly encloses all parts and are covered by an insulating material cap which results in the housing closure and which is also designed as an arc extinguishing chamber, characterized in that the essential components of the switch with electrical and mechanical function (such as contact system, release system, switch lock), viewed in one direction of expansion of the switch housing, are strung together without overlapping so that each component can be assembled or replaced individually. 2. Circuit breaker according to claim 1, characterized in that the essential components of the switch with electrical and mechanical functions (such as contact system, release system, Switch lock fastening means for the modules) on the front of the housing base plate in such a way are arranged so that they can be mounted or exchanged for themselves from this side. 3. Circuit breaker according to claim 2, characterized in that the electrical connection Coupling means (contact rails, terminal screws or the like) and the fastening means used to assemble the building blocks (fastening eyes, Screws) on both sides of the building blocks or their walls are arranged so that they are from the The front of the base plate is visible and freely accessible. 4. Circuit breaker according to claim 1 to 3, characterized in that in a known manner designed as rail pieces and the release system, if necessary, as a loop or winding penetrating lines on the one hand extending to outlets of the insulating housing Terminal pieces for the connection of external lines, on the other hand form contact pieces that protrude over the release system and extend in the direction of the contact system and are extended by flexible line pieces, which are also exposed to contact pieces of the contact system are screwable. 5.
