Definitions
- the present invention relates to a contact bridge cutout structure for circuit breaker comprising, in a box and for each pole, a mobile contact bridge associated with fixed contacts and a contact pressure spring, the bridge being stressed against the spring by a pusher which is subject to a mechanism for opening and closing the contacts.
- Such structures are well known and, in combination with arc extinguishing assemblies, have the function of opening the contacts of the respective poles in response to a voluntary or consecutive command to an electrical fault communicated to the mechanism. open close. It turns out to be desirable to confer on such a contact-carrying structure additional functions facilitating the mounting and / or operation of the circuit breaker.
- the object of the invention is in particular to transfer functions to the contact bridge structure, such as functions for guiding the pusher and / or for arcing, usually devolved to the case of the circuit breaker.
- the pusher of the contact bridge is guided in a fixed cage mounted in the housing of the device.
- REPLACEMENT SHEET trunk The function of guiding the pusher is therefore transferred to the breaking structure.
- the cutting structure can be re-used as a telescopic subassembly which is easy to install in the circuit breaker housing.
- the pusher preferably comprises at least one light dimensioned to allow the introduction of the contact bridge and an angular movement of the bridge relative to the pusher, the movement being therefore made possible although the pusher is guided in translation in the fixed cage .
- the fixed cage com ⁇ carries insulating lateral wings and a corresponding extension of its bottom wall to constitute cut-off pre-chambers which can be embraced by the ends of fins of arc extinguishing structures.
- FIG. 1 shows in exploded perspective a circuit breaker base fitted with breaking structures according to the invention
- Figure 2 is an elevation of a first embodiment of the cutoff structure
- Figure 3 is an elevation of a second embodiment of the breaking structure, with partial representation of elements voi ⁇ sins of the circuit breaker housing;
- REPLACEMENT SHEET Figure 4 is a side view along arrow F of Figure 3;
- Figure 5 is a top view, with partial illustration of neighboring elements.
- the circuit breaker illustrated in FIG. 1 comprises a box made of insulating material 10 of which only the base part is represented and, in this box, several polar current paths each provided with a breaking structure S with separable contacts.
- each pole path comprises two fixed contacts 11, 12 arranged on fixed contact pieces 13, 14 connected to terminals not indicated.
- it comprises two movable contacts 15, 16 associated respectively with the fixed contacts 11, 12 and arranged on an electrically conductive and movable bridge 17 to constitute a double-pole polar switch.
- a bottom wall 18 and interpolar partitions 19 there may be noted.
- the movable contact bridge 17 is biased by a mechanism (not shown) for opening and closing the contacts, this by means of a pusher 20 guided according to the invention in a fixed cage 21.
- the cage 21 is in insulating material and comprises a bottom wall 22, side walls 23 perpendicular to the polar partitions 19 and provided with windows 24 and solid side walls 25 parallel to the partitions 19.
- the bottom wall 22 of the cage is placed on the bottom 18 of the housing 10.
- FIG. 2 is illustrated in more detail a first embodiment of the cutoff structure S.
- the windows 24 of the lateral walls 23 of the fixed cage are dimensioned to allow the movement of the bridge of contact, in particular under the effect of the opening-closing mechanism in the event of
- the windows 24 define a high stop 26 for the contact bridge 17.
- a helical spring 28 of contact pressure is housed between the bottom wall 22 of the cage and the contact bridge 17 in a central recess 29 of the cage 21 which also serves as housing and guide in translation for the pusher 20. The latter is thus guided against the internal faces of the side walls 23, 25 of the cage by respective walls 30, 31.
- the walls 30 of the pusher are indented by lights 32 sized to allow, on the one hand, the introduction of the bridge into the pous ⁇ evening, on the other hand, an angular movement of the bridge relative to the pusher.
- a central orifice 33 is provided allowing the passage of the spring 28.
- the bottom wall 22 of the fixed cage has a ren ⁇ trant part 34 serving for the passage of a flat * folded part 35 of deflection of bow . which connects the respective interrupting chambers 36, 37 together.
- the fixed cage 21 of the cut-off structure S comprises insulating wings 38 parallel to the interpolar partitions 19 and extending longitudinally over a distance slightly greater than the length of the bridge 17 and of sufficient height to create a volume containing the cutting arcs.
- Finned assemblies 39 which have the function of splitting and driving out the arcs, comprise a certain number of fins 40 in the general shape of a U open on the contact side. The open area of the U embraces, by its wings 41, the insulating wings 38 of the fixed cage.
- the bottom wall 22 of the fixed cage is advantageously projecting to be housed in a central cavity 42 corresponding to an external projection from the bottom 18 of the housing 10, in order to reduce the overall height of the circuit breaker.
- Pins 43 are provided on the deck 17 to cooperate with corresponding shapes of the walls 30 of the
- REPLACEMENT SHEET pusher 20 in order to keep the bridge centered with respect to the pusher.
- the wings 38 of the cutting structure define, with a corresponding veil 44 which extends the bottom wall 22 of the cage, cutting pre-chambers 45, 46 housed in the chambers 36, 37.
- the fixed cage 21 is advantageously made of a material distinct from that of the base of the housing since the cage bears most of the cutting stresses.
- the structure described with regard to a circuit breaker obviously applies to different protective switch devices, in particular to contactors-circuit breakers.
