Definitions
- the invention relates to a miniature electric circuit breaker with molded insulating housing of parallelepiped shape having a handle projecting from a front face, a fixing base arranged on an opposite rear face, and a pair of narrow lateral connection faces, said housing containing a main arc extinguishing chamber with deionization plates, and a decompression chamber communicating the output of the main chamber with the external medium through an evacuation orifice.
- the exhaust of the breaking gases towards the external environment is generally effected by means of an orifice arranged in the narrow lateral face of the housing, that is to say in the environment in which is the connecting conductor.
- the lateral orientation of the exhaust of ionized gases may cause priming with the connecting conductor.
- the presence of flame arresters in the discharge orifice helps cool the ionized gases before they escape to the outside environment.
- the cooling gradient nevertheless depends on the structure of the flame arresters.
- the use of simple metal deionization grids does not allow optimum cooling of the ionized gases to be obtained, and the risk of external ignition remains for high currents.
- the use of special deionization boxes makes it possible to improve cooling, but their incorporation into the discharge orifice is incompatible with the size of the miniature circuit breaker.
- the object of the invention is to improve the exhaust of the breaking gas from a miniature circuit breaker.
- the circuit breaker according to the invention is characterized in that the evacuation orifice is provided in the rear face of the insulating housing, to divert the ionized gas flow from the side of the mounting base, to an area devoid of connecting conductors or live conductive parts, and that the decompression chamber comprises a baffle located in the vicinity of the orifice evacuation.
- the exhaust at right angles to the gases from the rear face of the box sends the hot gases to the rear part of the box, and prevents ignition in this region, regardless of the intensity of the current to be interrupted.
- a miniature circuit breaker 10 with an insulating housing 12 molded in a parallelepiped shape has a front face 14 from which protrudes a lever 16 of the mechanism, an opposite rear face 18 equipped with a mounting base 20, and a pair 22.24 narrow side faces for connection.
- the main arc extinguishing chamber 26 is formed by a stack of deionization sheets extending parallel to the base 20.
- the outlet 28 of the arc extinguishing chamber 26 is positioned against a perforated wall 30 allowing passage cut-off gas during the arc extinction phase.
- connection conductor 32 is introduced on the side of the face 22 into a cage of a connection terminal 34, which is housed in a cell 36 of the housing 12.
- the base 20 for fixing the circuit breaker 10 can be adapted on a mounting rail (not shown).
- a partition 38 of subdivision of the housing 12 is arranged between the cell 36 and the perforated wall 30 to confine a decompression chamber 40 at the outlet 28 of the extinguishing chamber 26.
- the decompression chamber 40 is closed on the side of the side face 22, so as to prevent any escape of ionized gases from the side of the connecting conductor 32.
- a discharge orifice 42 is provided in the rear face 18 of the housing 12, allowing communication between the decompression chamber 40 and the outside environment.
- the breaking gases are directed towards the decompression chamber 40, and are evacuated through the orifice 42 towards the outside environment, after passing through a baffle 44 (see arrow direction F).
- the presence of the discharge orifice 42 in the rear face 18 of the insulating housing 12 makes it possible to deflect the ionized gas flow on the side of the base 20, towards a posterior zone, devoid of active parts under tension.
