Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • the housing has two half-shell-shaped housing parts, which are connectable by means of a centrally passing connecting screw. At least one end of the connecting screw, a pressure plate is arranged, by means of which the force exerted by the connecting screw screw force is introduced as evenly as possible in the housing half.
  • the pressure plate is, as well as with the EP 1 139 496 A2 formed particularly solid and rigid so as to prevent deformation due to the screwing of the connecting screw as far as possible, so that the force applied by the screw is completely inserted into the housing half and is completely available for penetrating the insulation of the main conductors and branch conductors available.
  • a connecting device in which a seated on a relation to the terminal parts projecting end of the threaded bolt coil spring maintains the clamping pressure.
  • the supernatant of the threaded bolt caused by the helical spring is disadvantageous in particular with regard to casting of the mounted clamp and in particular can not be easily separated.
  • WO 01/45210 A1 a connecting device is known in which an arcuate connecting plate connects several, in the longitudinal direction of the conductor one behind the other terminal parts together and thereby full surface in contact with an arcuately curved lateral surface of the terminal parts.
  • the invention is based on the problem to provide a generic device, which has even better properties.
  • the device should ensure a permanent and good electrical connection between the main conductor and the respective branch conductor.
  • the assembly of the device should be further simplified and the safety during assembly further increased.
  • the dimensions of the cable branch terminal and thus the volume of a potting compound, the in a sleeve closing the cable branching clamp is to be further minimized for economic and ecological reasons.
  • the pressure plate is force-storing deformable due to the material used for this purpose and the geometric configuration.
  • the pressure plate may have at least two sections, which have a different bending stiffness due to their different geometric configuration, and of which at least one is force-storing deformable when tightening the screw.
  • the stored force in the pressure plate is initiated after completion of the tightening and thus after complete installation of the device in the device, thereby maintaining the contact force for the electrical connection between the main conductor and branch conductor permanently to a high degree.
  • pressure plates are arranged on both sides of the screw connection, in particular a pressure plate is assigned in each case to a housing part.
  • the pressure plate connects the function of a connecting or reinforcing element with that of a spring element, in particular, no separate spring element is required.
  • the pressure plate in the undeformed state is not the entire surface of a housing part.
  • the pressure plate can deform resiliently, without deforming by the deformation of the pressure plate by positive engagement and the housing part to which the pressure plate is in abutment.
  • the size of the device is not increased, in particular in the direction of the longitudinal axis of the threaded bolt, which is particularly advantageous.
  • the spring force can be initiated by the use of a plate exactly where it is most effective for maintaining the electrical contact, namely above or below the branch conductor or the associated contact elements.
  • the pressure plate for this purpose, optionally in conjunction with a receiving body, acts directly on the branch conductor.

  • a portion of the pressure plate when tightening the screw in abutment against the stop can be brought, so that overstretching of the pressure plate and thereby a plastic deformation is reliably prevented.
  • the stopper also makes it possible to transmit higher forces via the pressure plate than would be possible on account of the spring constant and the elastic deformation.
  • the stop is formed by bending a stop forming portion from a base portion of the pressure plate forming the further portion.
  • the pressure plate can be made as a stamped / bent part of a suitable spring steel.
  • the pressure plate is formed symmetrically to a longitudinal plane and symmetrical to a transverse plane, in particular axially symmetrical to an axis passing through an opening in the pressure plate, which coincides with the longitudinal axis of the screw of the screw connection.
  • the pressure plate in the center on a particular rigid contact surface for a screw connection element are connected to the introduction sections for the introduction of the spring force via a resiliently deformable portion.
  • the introduction sections are arranged on opposite sides of the contact surface. At right angles to the elastically deformable sections, the contact surface is connected to sections projecting at right angles to the base surface, which form the stop for the introduction sections.
  • the pressure plate can be inserted in a preferably made of an electrically insulating material receiving body.
  • the pressure plate is preferably not the entire surface of the receiving body, but especially in a first region, which is opposite to a second region, with the Receiving body can be brought into contact with the branch conductor.
  • the spring force is initiated exactly where it is most effective. In any case, a spring-elastic deformation of the pressure plate does not initially lead to a deformation of the receiving body.

  • the pressure plate derives its spring force predominantly or exclusively in the region of the first contact surface in the receiving body.
  • this can in any case be in the unstressed state of the contact surface for the screw connection having portion of the pressure plate in abutment with the receiving body, so tightening the screw leads to deformation of the pressure plate, but not on the receiving body and thus not on the associated housing part the device is transmitted. Rather, the deformation of the pressure plate leads to an initiation of the spring force only in the areas in which the receiving body with its first contact surface is in contact with the associated branch conductor.

  • the resulting power flow stabilizes the main and branch conductors to be connected together in the desired position and leads to a permanently secure electrical connection.
  • the screw connection of the housing parts can basically be designed as known from the prior art, in particular from US Pat DE 103 41 997 A1 ,

  • the support wedges are color-coded according to their geometric design, possibly also two-tone with different colors on the thick and thin side, so that a confusion or inadvertent rotation of the support wedges is almost impossible even for the untrained mechanic.
  • At least one housing part on a preferably integrally formed stop means When manual merging or mating of the housing parts while embracing the main conductor, the stop means comes into contact with an insulation of the associated main conductor. Under normal force application, the two housing parts are now not further merge.
  • the two housing parts on locking means by means of which the mated state of the two housing parts is latched, in particular that state is latched as a pre-assembly in which the stop means is in contact with the insulation of the main conductor.
