Definitions

  • the present invention relates to a block for connecting cables to an electrical appliance, comprising at least one connector constituted by a cage and by a movable wire clamp, under the action of a clamping screw, under a cell d 'a housing housing said connector.
  • connectors used to connect cables to an electrical device which are constituted by a cage and by a sliding wire clamp sliding under the action of a clamping screw, in the housing of the electrical device.
  • These connectors have the disadvantage of not allowing easy access to the clamping screw.
  • the aim of the present invention is to provide a connection block in which the clamping screws are made more easily accessible to a tool, while improving protection.
  • the solution adopted makes it possible to avoid wiring errors, to protect people against touching electrically conductive parts, whatever the diameter of the cables to be connected and to protect the connection parts against dust and impurities.
  • connection block according to the invention is characterized in that the slide has a U-shape, one branch of which is situated at the level of the screw head and that this branch situated at the level of the screw head carries, on the front , a mobile insulating protective cover which protects the front face of the slide, follows its movements and allows access to the screw head.
  • the front cover covers the top of the wire clamping slide so as to uncover or partially or completely seal a cell in the housing used for the passage of cables.
  • the block comprises at the rear, an insulating cover which covers the rear of the cage and follows its movements so as to uncover or close off a cell in the housing used for the passage of cables.
  • each of the connectors comprises a fixed electrical conductor connected to the device and being housed between the bottom of the cage and the slide and serving to clamp two separate cables.
  • the reference 2 designates an electrical appliance 2 (of the contactor type) on which are mounted two connection blocks 1 which are used for the connection of electrical cables marked 5 and 6. These blocks 1 are assembled to the appliance 2 by assembly means known per se.
  • Each block 1 comprises a housing 31 in which are provided 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 electric cables 5 and 6 to the device.
  • the outer side of the housing 31 is cut, above each connector 4, by two cells 37 and 38 which allow the ends of two cables 5 and 6 to be engaged in said connector.
  • Each connector is constituted by a cage 42 and by a movable wire clamp 43, both under the cells 37, 38 serving to receive the ends of cables 5, 6 to be connected.
  • the cage 42 the general shape of which is prismatic, consists of a stirrup 421 assembled to a cross-nut 422 pierced with a thread for a clamping screw 44 with a hollow head.
  • the cage can move freely in the chamber that contains it, depending on the diameters of the cables 5 and 6 to be connected.
  • the screw 44 has a hexagon socket head.
  • Each connector 4 also comprises a fixed electrical conductor 45 which passes through a slot in the housing and the extension of which carries a fixed 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 associated chamber 32 so that the conductor 45 is located between the bottom of the stirrup 421 and the cross-nut 422.
  • the wire clamping slide 43 is moved in translation by the screw 44 which is screwed into the cage 42.
  • This slide has a U shape.
  • the branch 431 of the slide 43 is used for tightening the cable 6 and is housed in the cage 42 then that 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 screw head.
  • 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 clamp 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 slide 43 and follows its movements so as to discover or partially or completely block the cell 38.
  • This insulating cover 35 is fixed in translation to the associated slide wire clamp 43 by a mechanical connection known per se. In the embodiment of FIG. 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 capable of allowing the screw 44 to be screwed in or out and a raised part 351 (in the form of a vee) serving as a screwdriver guide.
  • This screwdriver guide 351 owing to the fact that it follows the translational movements of the screw, thus facilitates access to the screw without forcing the cable operator to be positioned correctly relative to the block.
  • the block has at the rear an insulating cover 36 (made of plastic) which is carried by the rear of the cage 42 and follows its movements so as to uncover or partially or completely block 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 ensured by suitable means known per se (clipping of the cover 36 onto the cage for example).
  • Clearances 34 are provided on the top of the housing 31 to facilitate accessibility to the heads of the clamping screws 44. It is noted that a bridge 311 of the housing separates the cells 37 and 38. It is positioned above the conductor 45 and protects thus the users of 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, without increasing 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 clamping slide 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 releases a wiring space corresponding to the cable diameter 5.
  • the front socket 38 is then completely closed by the cover 35 (FIG. 3), which provides protection against touch, prevents the introduction of impurities and avoids the introduction of a cable outside the desired area.
  • the front face of the front cover 351 follows the screw head, which allows maximum visibility and accessibility of the screw.
  • the connector receives only a cable 6 in its front part, the rear cell 37 is then completely closed by the cover 36, which again provides protection against touch, prevents the introduction of impurities and avoids the introduction of a cable outside the desired area.
  • the block can receive as many connectors as necessary.
  • the connectors work whether the cage is immobilized (single wiring) or free (double wiring).
