Definitions

  • the present invention relates to a branch terminal for connecting a conductor of an insulated overhead line to an insulated branch conductor.
  • Terminals which comprise two half-shells of insulating material and which are connected together by a clamping screw.
  • Each half-shell has two channels, said channels facing each other and one of these being intended to receive the conductor of the overhead line, while the other is intended to receive the branch conductor.
  • Each half-shell is hollowed out of a housing intended to receive a contact strip which extends from one channel to the other channel and which is provided with teeth projecting in each channel so that, when tightening by the screw of the half-shells, the teeth pass through the insulators of the two conductors and thus provide the electrical connection.
  • Such a terminal is known from document DE-U-8704948.
  • Such branch terminals have a number of drawbacks.
  • the connection thus obtained is not waterproof, which in the long run presents a significant drawback.
  • the installation of the terminal is not very easy, because it is necessary to separate the half-shells from one another, place them on the conductors and assemble them with the screw provided for this purpose.
  • One of the aims of the present invention is, in particular, to remedy these drawbacks and to produce a terminal which offers complete safety from the point of view of sealing and which is much simpler and more practical to use than known terminals.
  • the terminal according to the invention is of the type comprising two half-shells of insulating material connected together by means allowing a certain sliding and a certain pivoting of one relative to the other, each half-shell comprising, at less, two parallel housings intended to each receive a contact rod, said housings being opposite, and each contact rod contact comprising on its face turned opposite the corresponding bar, in the vicinity of one end, teeth intended to perforate the insulation of the overhead line conductor and in the vicinity of the other end of the teeth intended to pass through the insulation of the bypass conductor, and a screw passing through a flared hole in one of the half-shells and screwing into a thread of the other half-shell in order to bring said half-shells together and to enclose the conductors, said terminal being characterized in that an elastic seal is interposed and inserted between the two half-shells, said elastic seal being made in one piece and being shaped to present a duct open laterally to allow the passage of the conductor of the overhead line and a second duct intended for receiving the
  • the elastic seal tends to maintain the terminal in a position which facilitates its positioning on the overhead line conductor, while the bypass conductor is held in the second conduit and when the half-shells are tightened. , the seal seals along the slots through which the teeth of the contact bars pass.
  • the slots of the seal which are crossed by the teeth of the contact bars are bordered externally by beads cooperating with corresponding notches of the half-shells.
  • the seal comprises a flexible and elastic bar supporting a cap.
  • a cap supporting a cap.
  • one of the half-shells has laterally, on two walls opposite, a handle, while the other half-shell has on the corresponding walls of the arches cooperating with said handles.
  • the screw is of the type comprising a head provided with means for taking a key and connected to said screw with a primer of rupture so that at a determined tightening torque the head separates from the screw, between the head and the screw a flat part allowing the grip of a tool being provided and having a dimension greater than that of the head. Thanks to the fact that the flat part has a dimension slightly greater than that of the head, the key used to tighten the screw and cooperating with the head can only slide on said flat part and it is therefore ensured that when the tightening torque will be reached the head will separate from the body of the screw.
  • Figure 1 is an exploded perspective view of a branch terminal according to the invention.
  • Figure 2 is an elevational view of the terminal of Figure 1 mounted.
  • Figure 3 is an elevational view showing the terminal permanently fixed.
  • the terminal shown in the figures is intended to be used to make a branch from a conductor of an isolated overhead line.
  • the terminal comprises a first half-shell 1, a second half-shell 2, an insulating joint 3 and four contact bars 5.
  • the half-shell 1 is made of an electrically insulating material and is formed of a body having, a bottom 11 and four side walls 12, 13, 14 and 15.
  • the bottom 11, in its central part, is pierced with a blind hole 7 provided with a thread 8.
  • Parallel to the walls 13 and 15 extend two partitions 17 which provide two housings 9 with said walls.
  • Each housing 9, in the vicinity of one end has a projection 10.
  • the walls 13 and 15 each have a large notch 19 and a smaller notch 20, corresponding notches being provided in the partitions 17.
  • Each housing 9 is intended to receive a bar 5 the latter being made of a material which is good conductor of electricity and which takes the form of a parallelepiped with, at one end on one face a recess 21 corresponding to the projection 10 and on the face opposite to that provided with said recess 21, at one end three teeth 22, 23 and 24 and at the other end two teeth 25 and 26.
  • the sides 13 and 15 are each integral with a handle 28.
  • the second half-shell is made of insulating material and has a general shape substantially similar to the first half-shell 1. It has four side walls 32, 33, 34 and 35, the walls 33 and 35 each having a large notch 39 corresponding to the notches 19 and a smaller notch 40 corresponding to the notches 20.
  • the half-shell 2 has in its central outer part a rounded domed part 41 pierced with an axial hole 37 which widens from the internal part of said half-shell 2 to the upper end of the domed part 41.
  • the half-shell 2 has internally housings 30 corresponding to the housings 9 and provided in the vicinity of the wall 34 with a projection, not visible in the drawings, and identical to the projections 10.
  • the walls 33 and 35 each have in their central part a hoop 38 slightly projecting and intended to cooperate with the bottom of the handles 28.
  • the axial hole 37 is intended to be crossed by a screw 45 for assembling the shells 1 and 2.
  • the screw 45 has at one end a thread 46 intended to cooperate with the thread 8 of the blind hole 7 and at the other end a flange 47 intended to cooperate with the curved surface 41, the flange being extended by a flat part 48 itself extended by a hexagon 49 with the interposition of a breaking primer 50.
  • the screw 45 is made, for example, of zamak and the thread 46 has a shape which, when combined with the thread 8, prevents the threads of said thread from being bent and sheared.
  • the flat part 48 is produced so that a tightening key mounted on the hexagon 49 cannot at the same time cooperate with said flat part 48.
  • the seal 3 is made of a flexible and elastic material and comprises a conduit 52 pierced by four slots 53 intended to be crossed by the teeth 25 and 26 of the four bars 5, two of which are arranged in the housings 9 and the other two in the housings 30.
  • the conduit 52 is intended to receive an insulated bypass conductor 57 whose free end is intended to project at one end of said conduit and to receive a cap 55 connected to the joint by a flexible and elastic bar 56.
  • the cap 55 is frustoconical so that the free end of the conductor is forced into said cap and so that it is protected.
  • the gasket 3 has in its central part a hole (not visible in the drawings) for the passage of the screw 45 and, a second conduit 58 with a C section having four slots 60 intended to be crossed by the teeth 22, 23 and 24 of the four corresponding bars 5.
  • the conduit 58 is intended to receive a conductor isolated from an overhead line and, thanks to the lateral opening, the lateral terminal can be easily mounted on said conductor 70.
  • the slots 60 are bordered on the outer side by beads 61 which are intended to cooperate with the notches 19 of the half-shell 2 and the notches 39 of the half-shell 1, while the edges 62 adjacent to the lateral opening of the conduit 58 are intended to cooperate with the free edges of the walls 12 and 32.
  • the slots 53 are also bordered by beads 63 intended to cooperate with the notches 20 and 30.
  • the terminal is delivered assembled as shown in FIG. 2 and the seal 3 maintains the half-shells 1 and 2 in a position ready for use, the arches 38 by co-operating with the bottom of the handles 28 constitute, on the one hand , a stopper ensuring the connection between the half-shells and, on the other hand, a joint.
  • the terminal is posed by engaging the conductor 70 in the conduit 58, the bypass conductor 57 being placed in the conduit 52 and its free end protected by the cap 55, then the screw 45 is tightened using a key cooperating with the hexagon 49 until it breaks along the primer 50.
  • the teeth 22, 23 and 24 pass through the insulator of the conductor 70, while the teeth 25 and 26 are inserted into the conductor 57 after passing through the insulator thereof so that the electrical connection between these two conductors is achieved.
  • the beads of the seal 3 are, during tightening, compressed around the slots and thus ensure sealing.
