- three facing holes are provided respectively in the wing nut, in the contact area and in the lower part of the compartment, said holes being intended for the passage of a fixing screw, a terminal or bar on the aforementioned contact pad
- a terminal cover plate is fixed to the rear part of the circuit breaker, said plate comprising, opposite each terminal, an opening for passage of the conductor, and the aforementioned pressure screw is integral in translation with a screen protective device able to partially close the corresponding opening of the plate when tightening the screw
- the aforementioned screen is constituted by an L-shaped part, one of the wings of which is mounted to rotate freely around the lower part of the screw between the shoe and the upper part of the block and whose other wing extends towards the upper part of the block
- the clamping shoe is fixed to one of the ends of the screw rod by crimping
- each of the compartments is associated with an additional contact pad intended to be electrically connected to an external device such as a voltage indicator lamp.
- the terminal cover plate is fixed to the rear part of the circuit breaker by means of rails provided on the internal surface of the plate cooperating with correspondingly shaped grooves formed in the rear part of the housing of the device.
- These plate fixing grooves have a T-shaped cross section and extend perpendicular to the longitudinal direction of the device, in spaces separating two adjacent compartments.
- the invention also relates to a breaking device such as a circuit breaker, comprising on at least one of its two large lateral faces, terminal compartments inside which extend contact pads, this device comprising at least one connection device comprising the characteristics described above taken alone or in combination
- this apparatus comprises several of these connection devices and at least one of the pad pressure screws is replaced by a screw with a convex end cooperating with a contact pad having the aforementioned recesses
- FIG. 1 illustrates in a perspective view comprising a cutaway, the rear part of a circuit breaker in a molded case
- Figure 2 is a perspective view illustrating a terminal according to a particular embodiment of the connection device of the invention
- Figure 3 is a perspective view illustrating the terminal of the previous figure equipped with a protective screen according to another characteristic of the invention
- FIGS. 4 and 5 are respectively front and sectional views of the terminal of the preceding figure and
- Figure 6 is a partial perspective view of the rear part of the circuit breaker, one of the contact pads is electrically connected to a terminal
- FIG. 1 we see a circuit breaker D in a molded case having a four-pole configuration and intended for use in a domestic or industrial application
- This case B has, on each of its two large opposite faces (of which only one 1 is visible on this figure) four terminal compartments 2, 3, 4, 5
- the connection of the charge bars 6 to 9 with the external electrical circuits to be protected is most commonly carried out by means of charge terminals, as is the connection network bars to network cables is made via network terminals, said terminals being mounted in the corresponding compartments at the places of installation
- FIG. 1 the connection network bars to network cables
- each charging station 10 to 13 consists of a metal block 14 of generally substantially parallelepipedal shape crossed by an elongated passage 15 inside which extends one of the contact pads 6 to 9 of the circuit breaker D
- the shape of each compartment 2 to 5 corresponds substantially to the external shape of the block 14 so that each block 14 is immobilized vertically after introduction into compartment 2 to 5
- each compartment 2 to 5 comprises on the one hand, at its two opposite lateral faces 2a, 2b, two branches additional 16, 17 intended to facilitate the removal of the terminal (for example by means of a tool) and on the other hand, at its lower part, two additional grooves 18, 19 intended to receive a wing nut 20 as will be described later
- Each block 14 has, at its upper part, a threaded orifice 21 through which is screwed a terminal screw 22, 23
- the terminal screw 22 of the first compartment 2 has a convex end 22a, while the screw 23 of the second compartment 3, is preferably
- claws 25 to 28 are intended to cooperate with four recesses 29 to 32, households in the corresponding contact area 6, said recesses 29 to 32 having a shape complementary to that of claws 25 to 28 and being located respectively opposite these latest
- these terminals will be suitable for tightening aluminum cables when they are equipped with a screw 22 with a curved end 22a, and for tightening copper cables or multi-cables, when they are equipped with a shoe 24 with claws 25 to 28, as previously described
- the terminal screw 23 provided with a shoe 24 is also equipped with a screen 33 of electrical protection
- This screen 33 is constituted by an L-shaped part, made of material plastic, one of the wings 33a of which is mounted to rotate freely at the lower part of the rod of the screw 23, being interposed between the shoe 24 and the upper part 34 of the terminal, while the other 33b of the two wings 33a , 33b extends towards the upper part of the terminal
- This screen 33 is intended to cooperate with an opening of corresponding shape 40 (visible in FIG. 1) formed in a terminal cover plate 41 placed on the rear part of the circuit breaker at the end of the wiring, in order to achieve an electrical protection meeting the IP2 standard in the manner which will be described later Referring more particularly to FIG.
- circuit breaker box is also provided on its two large opposite faces (of which only one is visible in this figure) with contact plugs 46, intended to supply by means of fast- on 47, devices such as indicator lights (not shown) intended to indicate the presence or absence of a voltage
- grooves 18, 19 allowing the fixing of crimp terminals 42 can also be used for fixing copper bars or other connection accessories
- terminals will be introduced as previously described in compartments 2 to 5, the contact areas 6 to 9 of which are intended to be connected to cables.
- the cables will be aluminum cables, it is preferable to equip the cages of a screw 22 with a curved end 22a
- the recesses 29 to 32 provided in ranges 6 to 9 will already allow better quality of contact
- the screws 23 will be fitted with a shoe 24 with claws 25 to 28 Tightening the screw 23 will cause the claws of the shoe 24 to be introduced into the recesses 29 to 32 of the contact pad 6, the cables being thus retained firmly between the pad 24 and the pad 6, from which a better quality of contact results.
- a device has therefore been produced which allows contact pads 6 to 9 to be connected to external conductors of different types of copper, aluminum, multicable cables, terminal, busbar, etc. in a simple and rapid manner.
