Definitions

  • the present invention relates to a block for connecting cables to a electrical appliance, comprising at least one connector consisting of a cage and by a movable wire clamp, under the action of a clamping screw, under a cell a housing housing said connector.
  • connectors for connecting cables to an electrical device which are constituted by a cage and by a sliding wire clamp sliding under the action a clamping screw, in the housing of the electrical appliance see, for example. FR 2601513A.
  • the present invention aims to provide a connection block in which makes the clamping screws more easily accessible to a tool, while improving the protection.
  • the solution adopted avoids wiring errors, protects the people against touching electrically conductive parts, regardless of diameter of the cables to be connected and protect the connection parts against dust and impurities.
  • connection block is characterized in that the slide has a U shape with a branch outside the cage located at the level of the head of screw and that this branch located at the level of the screw head carries, on the front, a movable protective insulating cover which protects the front face of the slide, follows its movements and allows access to the screw head and that the wire clamp has a branch movable in the cage and used to tighten the cable.
  • the front cover covers the top of the slide wire clamp so as to uncover or partially or completely seal a cell in the box used for the passage of cables.
  • the block comprises at the rear, an insulating cover which covers the back of the cage and follows its movements so as to discover or close a cell in the box used for cable passage.
  • each of the connectors comprises a conductor fixed electric connected to the device and housed between the bottom of the cage and the slide and used to clamp two separate cables.
  • Reference 2 designates an electrical appliance 2 (of the contactor type) on which are mounted two connection blocks 1 which are used for connection of electrical cables marked 5 and 6. These blocks 1 are assembled to the device 2 by assembly means known per se.
  • Each block 1 comprises a housing 31 in which are formed chambers 32 (as many as poles on the device) which open out towards the front by openings 33 and each contain a connector 4 suitable for connecting the cables electrical 5 and 6 to the device.
  • the outer side of the housing 31 is cut out, above each connector 4, by two cells 37 and 38 which allow the ends of two to be engaged cables 5 and 6 in said connector.
  • Each connector is constituted by a cage 42 and by a slide wire clamp 43 movable, one and the other, under the cells 37, 38 used to receive the cable ends 5, 6 to be connected.
  • the cage 42 whose general shape is prismatic, consists of a stirrup 421 assembled to a cross-nut 422 pierced with a thread for a clamping screw 44 with hollow head.
  • the cage can move freely in the chamber that contains it, depending on the diameters of cables 5 and 6 to be connected.
  • the screw 44 has a hexagon socket head.
  • Each connector 4 also includes a fixed electrical conductor 45 which passes through a light in the housing and the extension of which carries a contact of the contactor. This conductor 45 separates the two cells 37 and 38 which open on either side of this conductor 45.
  • the cage 42 is mounted in the chamber associated 32 so that the conductor 45 is located between the bottom of the stirrup 421 and the cross-nut 422.
  • the wire clamp 43 is moved in translation by the screw 44 which screws into the cage 42.
  • This slide has a U shape.
  • the branch 431 of the slide 43 is used to tighten cable 6 and is housed in cage 42 while the branch 432 of this same slide is housed outside the cage, at the height of the screw head.
  • a hole is made in this branch 432 to accommodate the screw head and allow the passage of a screwdriver allowing the screwing or unscrewing of the screw.
  • the translational connection between the screw 44 and the slide 43 is provided in one direction, by the support of the end of the screw and in the other direction by a flange of the head of screw.
  • the screw-nut system 42-44 allows, by rotation of the screw 44, to tighten on the one hand a cable 5 between the bottom of the stirrup 421 and the conductor 45 and on the other hand a cable 6 between the conductor 45 and the wire clamping slide 43.
  • the block has, at the front, a movable insulating cover 35 (made of plastic) which covers the front (on the side of the screw head) and the top of the wire clamp 43 and follows its movements in order to partially or completely uncover or seal the cell 38.
  • This insulating cover 35 is fixed in translation to the associated wire clamp 43 by a mechanical connection known per se. In the embodiment of the figure 5, this connection is ensured by a finger 354 of the cover which is housed in a hole in the slide 43.
  • the front face of the cover 35 has a hole 353 adapted to allow the screwing or unscrewing the screw 44 and a raised part 351 (in the form of a vee) serving screwdriver guide.
  • This screwdriver guide 351 because it follows the movements of translation of the screw, thus facilitates access to the screw without forcing the cable operator to properly position in relation to the block.
  • the block has at the rear, an insulating cover 36 (made of plastic) which is worn from the back of the cage 42 and follows its movements so as to uncover or seal off partially or completely the cell 37.
  • This movable insulating cover 36 covers the rear of the stirrup bridging 421.
  • the mechanical connection between this rear cover 36 and the cage 42 is provided by suitable means known per se (clipping of the cover 36 on the cage for example).
  • Clearances 34 are arranged on the top of the housing 31 for facilitate accessibility to the heads of the clamping screws 44. It is noted that a bridge 311 of the box separates the cells 37 and 38. It is positioned above the conductor 45 and thus protects users from contact with this driver.
  • the rear edge 352 of the front insulating cover 35 serves as a wire guide for a cable such as 6.
  • the front edge 361 of the rear insulating cover 36 serves as a wire guide for a cable such as 5.
  • the housing 31 has, between the connectors 4, grooves 39 which facilitate access to terminals such as coil terminals for example, this without increase the size. They are suitable for receiving parts of additives 7.
  • the front insulating cover 35 follows the movement of the tightening screw 44 and the wire clamp 43 and frees up a wiring space corresponding to the diameter of the cable 6.
  • the rear insulating cover 36 also follows the movements of the cage 42 and frees up a wiring space corresponding to the diameter of the cable 5.
  • the cell front 38 is then completely closed by the cover 35 ( Figure 3), which provides protection against touch, prevents the introduction of impurities and prevents the introduction of a cable outside the desired area.
  • the front of the front cover 351 follows the screw head which allows maximum visibility and accessibility of the screw.
  • the cell rear 37 is then completely closed by the cover 36, which again provides protection against touch, prevents the introduction of impurities and prevents the introduction of a cable outside the desired area.
  • the block can receive as many connectors as necessary.
  • the connectors work when the cage is immobilized (simple wiring) or free (double wiring).
