Definitions
- the present invention relates to a protection relay, in particular of the thermal type, capable of being connected to a contactor, and comprising a housing provided with upstream and downstream power connection terminals and control terminals, and provided on the front face with manually operated actuating or regulating members.
- a protection relay in particular of the thermal type, capable of being connected to a contactor, and comprising a housing provided with upstream and downstream power connection terminals and control terminals, and provided on the front face with manually operated actuating or regulating members.
- the upstream power terminals and the control terminals of such a protection relay must be connected to respective power and control terminals of a neighboring contactor.
- the invention also relates to a protected control assembly including such a protection relay.
- thermal protection relays are described, the housing of which is provided with a flap which can be folded down by pivoting or translation on selection, control or adjustment members which must remain inaccessible in normal service. .
- the shutter leaves permanently accessible a stop button and a reset button. The operator can thus freely, by means of the stop button, cut a power line via a contactor whose coil is connected to the thermal relay or, by means of the reset button, manually return the thermal relay to its operational state after a trigger.
- the operator can only intervene on the adjustment button or on the manual / automatic mode selector (H / A) only when the shutter is open.
- the power interconnection between relay and contactor remains hidden when the two devices are assembled.
- the control interconnection that the user must necessarily implement between the control terminals of the relay and those of the contactor leaves the conductors at the front of the devices visible and easy to handle. This can be annoying.
- the object of the invention is to provide, by simple arrangements, a concealed control interconnection of the relay and of the contactor.
- the relay box comprises, set back from its front face, at least one recess used for the passage of an interconnection conductor between a relay control terminal and a contactor control terminal, which recess is hidden in normal service by a cover and houses part of a front prewiring additive comprising the interconnection conductor (s).
- the cover may be a flap which authorizes and respectively prohibits, in an open and respectively closed position, the operation of an actuating or regulating member with limited access.
- the cover may simply be a fixed part of the protection relay housing.
- the prewiring additive can be housed in the recess, either when the recess is provided on a front face of the protective relay box concealable by a flap, or when the recess is provided in a fixed part of the recessed housing with respect to this front face.
- the invention also relates to a protected control assembly formed by the protection relay and the contactor arranged and interconnected as described above.
- Figure 1 shows a side view of a protected electrical control assembly consisting of a contactor and a thermal type protection relay.
- Figure 2 shows in perspective the whole of Figure 1.
- FIGS 3 and 4 show in perspective the protection relay with its flap open, respectively without pre-wired additive and with such an additive.
- FIGS 5 and 6 show in perspective a variant of the protective relay with a pre-wired additive, respectively with the flap open and closed, the pre-wired additive being shown respectively before and after installation.
- the control and protection assembly shown comprises a contactor with a housing 10 and a thermal protection relay with a housing 20 assembled with the contactor.
- the housing 10 of the contactor has upstream power terminals 11 and downstream power terminals 12, as well as towards the front, that is to say on the side accessible to the user, a control and command terminal block 13.
- the term control used subsequently designates indifferently the control - or signaling - function and the control - or switching - function of the state of the contactor via the supply of the coil of the latter.
- the control terminal 13, arranged in advance relative to the main front face 14 of the housing 10, which face is provided with the access openings of a tool at the terminals 11, 12, for its part has upstream control terminals 15 and downstream control terminals 16, capable of being connected to a high potential and respectively a low potential.
- the housing 20 of the thermal relay has upstream power terminals 21 constituted by pins capable of penetrating into the downstream terminals 12 of the contactor; the housing 20 also has downstream power terminals 22 to be connected to a load, as well as control terminals 23 to be connected to some of the downstream control terminals 16 of the housing 10 by means of rigid or flexible conductors C, and to be optionally connected signaling devices. These conductors are arranged to be mechanically linked together in the form of a pre-wired additive. It should be noted that the terminals 23 are located on the downstream side, opposite the contactor.
- the housing 20 is provided on its main front face 24 with members with limited access, in particular with actuation or adjustment function, and members 25 with permanent access, in particular with stop and / or reset function.
- the limited access members 24 are for example an adjustment button 24a and a selection button 24b making it possible to choose the operating mode - manual or automatic - of the relay, and the permanent access members 25 are for example a reset button and or two buttons performing these functions separately.
- the housing 20 also includes a flap 26 which constitutes its front face 24. In the absence of such a flap, the front face 24 would of course be fixed. Part 26 authorizes in the open position (see Figures 3, 4 and 5) and respectively prohibited in the closed position (see Figures 1, 2 and 6) access to the organs 24. It offers an opening 26a allowing permanent access to the organs 25.
- the flap 26 is foldable on the members 24,25 by pivoting or sliding relative to the housing 20.
- a recess such as a channel 27, intended for the passage of two conductors, and comprising for example two respective channels located on either side of the stop and reset button 25.
- the channel is located to the right of the housing so that its channels are substantially at the level of two control terminals 23 of the relay.
- the channel 27 is formed in the housing 20 or in the flap 26 and opens towards the upper flat face 28 of the housing 20, adjacent to the contactor, by a flared opening 29 facilitating the routing of the conductors towards the respective downstream terminals 16-A2 and 16-14 of the contactor.
- the opening 29 opens onto a space 13a open towards the front and delimited by the control terminal block 13, the front face 14 of the contactor and the high face 28 of the relay.
- the thermal relay is also arranged to allow the accommodation of an additive front control pre-wiring sub-assembly provided with interconnection conductors; the additive is shown in a first variant in FIG. 4 and in a second variant in FIGS. 5 and 6.
- the prewiring additive 30 shown in FIG. 4 is housed in the channel 27 and comprises two substantially rigid interconnection conductors 31, 32; at their lower part, the conductors 31, 32 are linked by an insulating pad 33 and are capable of engaging in the terminals 23 situated opposite the contactor; at their upper part, they are bent so as to be able to penetrate into the terminals 16 of the contactor.
- the shutter 26 in the closed position hides the members 25 and the channel 27 and helps to hide and maintain the conductors 31, 32.
- the prewiring additive 40 shown in Figures 5 and 6 is housed in a recess 27 'of the housing 20 of the relay.
- the recess 27 ' comprises two channels located behind a fixed part 26' of the housing close to its front face; this part 26 ′ constitutes the cover intended to hide it, so that the channel 27 ′ opens on the one hand on the face 28 and on the other hand, directly and through the interior of the housing 20, in the housings- two relay control terminals 23. It can be noted that these terminals are therefore accessible from the top and from the inside of the box, as well as from the bottom from the outside of the box.
- the additive 40 comprises two rigid interconnection conductors 41, 42.
- the conductors 41, 42 are linked at their upper part by an insulating stud 43 provided with openings 43a which allow access of a tool to the power terminals 12 of the contactor; they terminate at their upper part by two pins 41a, 42a intended to be introduced into the terminals 16 of the contactor and at their lower part by two pins 41b, 42b intended to penetrate into the two channels of the recess 27 'for enter the control terminal 23 of the relay directly, perpendicular to the face 28 of the housing 20.
- the pins can be rigid, or allow a spacing or orientation adjustment.
- the channels forming the recess 27 ' also provide guidance when the additive 40 is penetrated and excellent retention thereof.
- the described protection relay makes it possible to connect both flexible individual cables C as well as cables 31, 32 or rigid conductors 41, 42 integrated in a specific additive 30.40, while ensuring the desired masking.
