Definitions

  • the invention relates to a terminal block for the electrical connection of electrical energy supply cables comprising at least one electrical conductor of high mechanical rigidity, in particular for supplying user devices, in which a connection device is mounted between the two. previously stripped ends of the conductors.
  • the present invention aims to overcome these drawbacks.
  • each connection device comprises at least two connection terminals, each of which is connected to one of the ends of the cut conductor and which are electrically connected together by means allowing a relative displacement of a terminal compared to the other.
  • the means of electrical connection of the terminals is formed by a flexible cable, each end of which is fixed to a terminal.
  • the means of electrical connection of the two terminals is of the type with connection screw and oblong hole.
  • Figure 1 is a perspective view of a first embodiment of a terminal device according to the invention.
  • FIG. 2 is a top view, with parts broken away, of the terminal block device according to FIG. 1.
  • Figure 3 is a sectional view along line III-III of Figure 2.
  • Figure 4 is a perspective view of a second embodiment of a terminal device according to the invention.
  • Figure 5 is a schematic view of a third embodiment of a terminal device according to the invention.
  • the terminal block which has the general reference 1 is mounted between the conductors of cables A, B, four in number, which are designated respectively by a and b.
  • the terminal block supplies electrical power to user devices.
  • Conductors c constitute the connections which are provided for this purpose.
  • the connection terminal block 1 can be intended for example for the connection of large cross-sectional and therefore very rigid cables to a three-phase electrical power supply network.
  • the terminal block according to the invention is advantageously usable in the field of public lighting at the foot of candelabras.
  • the terminal block according to the invention is mounted vertically. It includes for each pair of conductors a, b a connection device.
  • the four devices are juxtaposed. They have the same structure and therefore bear the same reference 2.
  • Each connection device 2 comprises two connection terminals 4 and 5 intended to receive respectively a conductor a and b of cables A and B. The ends of the conductors are stripped.
  • These terminals 4 and 5 come respectively to be housed in cells 6 and 7 of the body 8 made of an electrically insulating material of the terminal block.
  • Each cell 6 offers a large vertical positioning space for housing the terminal 4 and each cell 7 is adapted to receive the terminal 5. It can thus be seen that the terminal device comprises a row of four juxtaposed upper cells 7 and a row of four lower juxtaposed alveoli 6.
  • Each terminal 4, 5 is of the barrel type with screw tightening, that is to say it is produced in the form of a parallelepipedic body which comprises a rectilinear passage 10 for the introduction of the stripped end of the respective conductor a , b and a screw fixing the conductor 11 in the terminal.
  • the screw engages in a suitable tapped hole made from the outer surface 12 of the terminal, which is released and thus accessible in the cell 6 or 7.
  • the upper terminal 5 has one more great length that the lower terminal 4 to be able to fix in its passage 10, axially aligned with the conductor b, the conductor c supplying a user device.
  • This conductor c is also fixed in the terminal by a screw 13.
  • the two terminals 4 and 5 are electrically connected by a flexible conductive cable or an advantageously flat conductive braid 15, the ends 16 and 17 of which are preferably welded to the respective faces 18 opposite the faces 12 for engaging the fixing screws.
  • a feature of the invention lies in the fact that the end 17 of the cable 15 is welded to the upper terminal 5 so as to form a loop 20 which extends upwards. This loop makes it possible to offer a maximum length to the cable, in particular in the space 21 of the cell 7, delimited between the terminal 5 and the bottom 22 of the cell.
  • the cell 7 comprises lateral supports 24, 25 produced in the form of shoulders situated at a level suitable for obtaining the space 21 necessary for housing the loop 20 of the cable 15.
  • FIG. 3 it can be seen that the input of the conductor b of the terminal 5 is located on a separate and higher plane from that of the terminal 4 so as to facilitate the direct passage of the conductor b to the above the latter.
  • Each of the lower cells 6 comprises in its lower and upper front walls 26, a recess 28 for the passage of the conductors a and the cable 15.
  • An insulating plate 29 covers all the cells 6, so as to be able to block towards the bottom of each cell each of the terminals 4.
  • the plate 29 has for this purpose recesses having a shape complementary to the shape of the side walls 27 to allow passage of these, as shown in particular in Figure 2.
  • the plate 29 is designed to have an elasticity allowing it to be fixed or snapped onto the side walls 27 of the cell or on the body of the terminal block, using a locking device shown at 30 ( Figure 3) and include for example a locking projection.
  • the upper terminals 5 can be locked in their cell 7, bearing on the support flanges 24, 25 by means of an insulating housing 31 which snaps or is fixed on the side walls 32 of the cell or on the body of the terminal block, while providing a vertical mounting clearance, the value of which will be demonstrated below.
  • Each upper cell 7 comprises, in its front surfaces 34, openings 35, 36 for the passage respectively of the conductor b and of the cable 15, on the one hand, and of the cable c, on the other hand.
  • the terminals 5 are left accessible.
  • the mounting of the second cable in cut B will be identical by cutting the cable so that its end is substantially in the middle, along the longitudinal axis of the cell 7 and by connecting each end of the conductor b previously stripped in its terminal 5.
  • the great flexibility and the good length of the cable 15, advantageously in the form of a braid makes it possible to easily release the terminals 5 from their cell 7 and to bring them from the top to the bottom towards the stripped end of each of the conductors so to engage them and fix on the ends of these. This operation avoids the reverse operation, that is to say arching the conductors to introduce them into the terminals 5, as is the case in the prior art.
  • the conductors connected to the terminals 5 pass over the terminals 4 previously introduced into their cell 6 and capped by the insulator 29. They can therefore be introduced into the terminals 5 and the cells 7 without undergoing bending. This avoids mechanical forces being generated within the conductors. These efforts would be harmful for the installation of the cables in the terminal block and could in the long term cause the loosening of the screws 11 of the terminals.
  • the terminal block according to the invention therefore relates in over time, a very good quality of conductivity and great ease of assembly.
  • the terminals 5 are then introduced into their reciprocal cell 7 bearing on the lateral supports 24, 25 and are held in position by the second housing 31 put in place by snap-fitting, while providing the above-mentioned vertical mounting clearance.
  • FIG. 4 shows a second embodiment of a terminal device according to the invention.
  • the terminal block according to FIG. 4 comprises two terminal bodies 40 and 41, each associated with a cable and designed to allow the mounting of the four conductors. Each body can thus be considered to be formed by assembling the four terminals 4 or 5 of the embodiment according to FIGS. 1 to 3.
  • the two bodies 40 and 41 are electrically connected by an insulated flexible conductive braid 43.
  • the body 40 includes means for connecting the supply c conductors to the user devices.
  • the body 40 could be fixed on a support using screws 44 engaging in oblong holes, the body 41 being held in place by the rigidity of the conductors to which it is connected.
  • the through hole 42 of the screws for fixing the ends of the conductors in the terminal block also has an oblong shape in order to be able to provide axial play when these ends are assembled.
  • each pair of conductors to be connected are associated with two terminals 46, 47.
  • the terminal 46 comparable to terminal 5 in FIGS. 1 to 3 comprises a fixing lug 48 which carries at its end free a small connection terminal 49 of the cable c and has an oblong recess 50 which extends in its longitudinal direction and allows the passage of a screw 51 capable of engaging in a threaded hole 52 of a lug 53 of the other terminal block 47.
  • the oblong hole 50 provides sufficient vertical clearance for fixing the terminal 46 to the terminal 47 after the cable B has been mounted. This embodiment thus makes it possible to avoid any mechanical stress within the cables during their mounting on the terminal block device.
