  having a contact surface for the conductor

  and a contact light having a contact screw for the bypass conductor, an opposing clamping jaw having a contact surface for the main conductor, a clamping screw pressing the jaws together, the two jaws in clamping position supporting each other on the side

away from the main driver.

  It is known from DE-GM 1,827,863, a comparable derivation derivative. It includes a clamping jaw, an opposing clamping jaw and a screw clamping the two jaws together. One side of the clamping jaws has a

  contact area for the main driver, respec-

  tively. The opposing clamping jaw has a

  contact surface in the form of a cylindrical blind hole

  drique whose axis is perpendicular to the driver

  main. The blind hole receives the branch conductor-

  which can be electrically connected to the jaw of

  opposite clamping through a contact screw.

  In the clamping position, the two jaws support each other. To connect the main conductor to the service conductor, screws

  separated and corresponding threaded holes are provided.

  The object of the invention is to improve this known tap terminal so that a tapped hole

  and that the connection screw for the conductor

  connection are not necessary. ' This object is achieved by the fact that the contact light for the connection conductor is arranged

  in the clamping jaw to allow the introduction of

  the end of the clamping screw, designed to fit into the clamping jaw, into the contact lumen, and that above the opposing clamping jaw, a clamping nut, acting on the jaw opposite and adjacent, is screwed on the

clamping screw.

  With the bypass terminal according to the invention, the presence of an additional threaded hole for the connecting screw of the branch conductor as well as the connection screw itself is avoided, whereas the previous advantages, for example an independent clamping of the

  main and branch conductors are retained.

  Other features of the invention will be

described below.

  The invention will be described in more detail with reference to the accompanying drawings by way of non-limiting example and in which the single figure is a view of

  side of the branch terminal according to the invention.

  The branch terminal 1 comprises a clamping jaw 2, an opposing clamping jaw 3 and a

tightening screw 4.

  The clamping jaw 2 has a contact surface for a main conductor 6. As the main conductor, bare or insulated conductors having a circular or segmental cross-section may be used. The main conductor 6, as shown, is a conductor having a segmental cross section, no insulation being shown. Therefore, as contact surface 5, parallel longitudinal cutting edges 7 are provided, a groove 8 being sandwiched therebetween. The contact surface 5 of the jaw 2 of serrarge is disposed on the

  left side of the central plane y-y.

  As can be seen, the contact surface, in the form of the longitudinal cutting edges 7, is configured to allow contact with the main conductor 6 of different dimensions. The longitudinal cutting edges 7 intersect the outer insulation of the corresponding main conductor 6 and an electrical connection is thus established with the metal core

driver 6.

  In addition, the clamping jaw 2 has a contact light 9 for the branch conductor (not shown). The contact light 9 is advantageously configured in the form of a cylindrical hole 10; the axis of this hole is parallel to the longitudinal cutting edges 7 and is arranged to be in the central plane y-y; it is advantageously suitable for branch conductors having stripped ends and a section

circular cross.

  It is also possible to provide a hole

  one-eyed (not shown) whose central axis is

  dicular to the longitudinal cutting edges and which is open towards the right end of the clamping jaw 2. It is therefore possible to connect the driver of

  connection perpendicular to the main conductor.

  The tightening screw 4 is inserted at its end 11 into the contact lumen 9 and makes the electrical connection to the inserted branch conductor. For this purpose, the tightening screw 4 is screwed into a

  Tapped hole 12 of the clamping jaw 2.

  The end 11 of the clamping screw 4 could also have a cutting member called a cutter to allow an electrical connection to the core of a branch conductor having an external insulator, when

of the introduction.

  - On its upper surface, the clamping jaw 2 has an abutment surface 13 terminating at an O-ring portion 14. The right end of the opposing clamping jaw 3 has a tapered end portion 15 having a curved end surface 16. This end surface 16 of the end portion 15 is supported by the abutment surface 13 of the clamping jaw 2, and the O-ring portion 14 preventing the end portion 15 from

  twist and move laterally.

  The left side of the clamping screw 2 has a contact surface 17 for the driver

  This contact surface 17 is advantageously

  formed by two longitudinal parallel cutting edges 18, a groove 19 being interposed between them. The longitudinal cutting edges 18 of the opposing clamping jaw 3 are substantially aligned with the ridges

  longitudinal section 7 of the clamping jaw 2.

  They are symmetrical with respect to the central plane x-x

  between the parallel longitudinal cutting edges 7, 18.

  These can also be toothed.

  In place of the longitudinal edges 7, 18, contact surfaces 5, 17 may be provided in the form of circular segmental surfaces for

bare drivers.

  The tightening screw 4 has a poly-

  nale, preferably quadrangular 20. It can be tightened by means of a tool such as a key. By pressing the clamping screw 4 into the threaded hole 12, the connection of the end 11 to the

  connection in the contact light.

  In addition, a hole 21 is screwed onto the clamping screw 4 by means of a wrench, preferably with hexagonal surfaces. Between the nut 21 and the upper surface 22 of the opposite clamping screw 3, there is provided a washer 23, the upper surface 24 being level and the lower surface 25 having a curved shape corresponding to that of the upper surface. 22 of the opposite jaw 3 clamping. By tightening the nut 21, the opposite clamping jaw 3 is compressed against the clamping jaw 2, the longitudinal edges 7, 18 of

  penetrating cut in the main conductor 6.

  As can be seen, the main conductor 6 and the branch conductor can be introduced independently and successively into terminal 1

  bypass and they can be connected.

  In addition, the opposing clamping jaw 3 has an elongate hole 26 for the insertion of the clamping screw 4, the elongate hole 26 being perpendicular to the longitudinal axis of the contact lumen 9. Therefore, the opposing clamping jaw 3 can adapt itself to different cross sections of conductor. It goes without saying that many modifications can be made to the bypass terminal described and

  shown without departing from the scope of the invention.
