Definitions
- the object of the invention is to remedy these drawbacks and to produce, for each pole of a switch device of the type mentioned above, the same magnetothermal tripping sub-assembly which is by design very compact.
- Another object of the invention is to provide such a suitable magnetothermal sub-assembly which is easy to assemble and to assemble in the switching device.
- the conductive support of the bimetallic strip and the coil carcass are mounted in mutual overlap and are respectively fixed to the base by means of cooperating engagement members.
- the two large faces of the bimetallic strip are parallel to the longitudinal direction of the support.
- the lever is a direct percussion lever for the mobile contact support and has advanced coaxial pivots substantially at the foot of the bimetallic strip.
- the base of the magnetothermal sub-assembly and / or the wings of the coil carcass advantageously have guide ribs intended to slide in grooves made in the housing during assembly of the magnetothermal sub-assembly in the housing.
- the electrical protection switch device designated by the general reference 10 in FIGS. 1 and 2, is a low-voltage double-pole double-circuit breaker with a single pole has been shown.
- the apparatus 10 comprises an insulating housing 11 composed of a base 12 and a cover 13.
- the housing comprises, on its front face, a projecting part 14 and, on its rear face, elements 15 serving for fixing of the device by snapping onto a standard profile.
- Each pole of the apparatus 10 comprises a contact bridge 17 carrying two movable contacts 18, 19 arranged on either side of a median plane P - common to all of the poles - and intended to occupy either a position of closure in which they cooperate respectively with two fixed contacts 20, 21 formed on respective conductive parts 22, 23, or an open position in which they are separated from the fixed contacts 20, 21 following an automatic tripping in the event of a fault in overcurrent or manual control.
- the conductive part 22, FIGS. 1 and 2 is directly connected to a first electrical connection terminal 26, while the conductive part 23 is electrically connected to a second electrical connection terminal 27 via a series electrical assembly composed of a thermal trip device with bimetallic strip generally designated at 28 for protection against overload currents, and with an electromagnetic trip device with striker generally designated at 29 for protection against short-circuit currents.
- thermal 28 and electromagnetic trip devices with striker 29 of each pole, as well as the associated connection terminal 27, form an integral part of the same monobloc sub-assembly for magnetothermal trip designated by the general reference 30, as we will describe in detail later.
- the apparatus 10, FIGS. 1 and 2 also includes a triggering mechanism with lock 31, common to all the poles and arranged in a central compartment 32 of flat shape, that is to say of relatively small thickness perpendicular to the median plane P.
- FIG 1 there is partially shown an embodiment of the lock 31 in the armed position; this comprises a pivoting hook 33 having a spout passing through a lumen 36 formed in a side wall 31a of the lock situated on the side of the magnetothermal sub-assembly 30, and being engaged with a bearing surface of an opening 37 made in the vicinity of the upper end of a flat piece in the form of a strip 38 adjacent to the side wall 31a of the lock, as well as an opening member 39 subject to the action of the hook 33.
- a pivoting hook 33 having a spout passing through a lumen 36 formed in a side wall 31a of the lock situated on the side of the magnetothermal sub-assembly 30, and being engaged with a bearing surface of an opening 37 made in the vicinity of the upper end of a flat piece in the form of a strip 38 adjacent to the side wall 31a of the lock, as well as an opening member 39 subject to the action of the hook 33.
- the striker of the electromagnetic trip device 29 of each pole is a pivoting lever 41 which, in normal service (FIG. 1), on the one hand is engaged with a bearing surface of an opening 42 made in the vicinity of the lower end of the strip 38 and, on the other hand, opens out as close as possible to the median plane P by passing through a lumen 43 formed in the side wall 31a of the lock 31.
- the contact bridge 17, FIG. 1 is biased in the direction of closing of the contacts by a return and pressure spring 44 which also bears against the bottom of the housing 11.
- the contact bridge 17 can be controlled in the direction of the opening of the contacts by a drive pusher 45 carrying the bridge and belonging to a part common to all of the poles, which part comprising as many pushers as there are poles.
- the pusher 45 is itself driven, following a short circuit detected by the electromagnetic trip device 29 of each pole, by the striker lever 41 pivoting in a plane substantially transverse to the median plane, and this after triggering the lock 31, of which time to response is greater than the time of percussion of the striker lever 41, by means of the strip 38 driven parallel to the median plane under the action of a traction exerted by the lever during its pivoting; the striker lever 41 therefore constitutes a very rapid contact opening member, while the opening member 39 of the lock 31 in the tripped position constitutes in this case a member for confirming the opening of the contacts, the member 39 moving parallel to the median plane ( Figure 2).
- the pusher 45 is also driven by the opening member 39 of the lock 31 following the release of the latter either by a manual control member, or by a control device (not shown) subject to a trigger bridge partially shown at 48 in FIGS. 1 and 2 and requested by the thermal trigger 28 of each pole in response to an electrical overload detected by the latter.
- an opening push button or "stop” button causing the triggering of the lock 31 is shown at 50, and at 51 a reset and closing push button or “on” button, these push-buttons 50 and 51 being arranged in the compartment 32 so as to be able to protrude at the front of the housing 11.
- the push-buttons could be replaced for example by tilting buttons, or even by a single rotary lever for resetting, closing and opening, without departing from the spirit of the invention.
- the strip 38, the opening member 39 and the striker lever 41 are in the high position (FIG. 1) under normal operating conditions, the operating push button 51 being pressed. They are all three in the low position (FIG. 2) when a short circuit has been detected by the electromagnetic trip device 29; on the other hand, the opening member 39 is alone in the low position when an electrical overload has been detected by the thermal trip device 28 or when the stop push-button 50 has been pressed.
- the thermal trip device 28 of the magnetothermal trip sub-assembly 30 of each pole comprises a thin bimetal strip 55 of generally rectangular elongated shape extending in a plane QQ ′ and having a first free end 56 and a second end or foot 57 assembled by any suitable fixing means on a support plate 59 of generally rectangular shape, of given thickness e , made of an electrically conductive material and extending in a plane RR ′ perpendicular to the plane QQ ′.

- the base 72 of this sub-assembly 30 extends longitudinally in a direction perpendicular to the median plane P.
- an electrical overload detected by the bimetallic strip 55 causes it to deflect which actuates the trigger bridge 48, which drives a control device, symbolized by the arrow F, which acts on the hook 33 to release it from the strip 38; by this release, the hook 33 pivots clockwise and triggers the lock 31.
- the opening member 39 descends to strike the pusher 45 which drives the bridge 17 and causes the contacts to open.
- the plunger core 93 (FIG. 1) moves by attraction towards the fixed core 92 and causes the striker lever 41 which is coupled to it to pivot.
- the lever 41 drives the slide 38 which descends to trigger the lock 31 by releasing the hook 33 vis-à-vis the slide, the released hook 33 pivoting clockwise.
- the response time of which is greater than the time of percussion of the lever 41 the latter strikes the pusher 45 which drives the bridge 17 and causes the opening of the contacts, this opening being confirmed by descent and application of the 'opening member 39 on the pusher 45 ( Figure 2).
- the striker lever 41 - plunger core 93 assembly returns to its position in FIG. 1 under the action of the return spring 94, the return of the striker lever 41 causing the strip 38 to rise.
