Definitions

  • the invention relates to a connection device for insulated electrical conductors that penetrate the conductor insulation and thereby making contact with the conductor core.
  • Such stripping-free connection devices have the Advantage that the conductor to be connected is only cut off and the ends no longer need to be prepared. on the other hand such devices are often complicated and expensive, which ultimately saves time in work preparation is nullified again.
  • connection device for insulated electrical conductors known in which the conductor insulation is penetrated to to make contact with a conductor soul.
  • the Connection device comprises a screw terminal which consists of a Sleeve or socket and a screw that can be screwed into this consists.
  • the screw moves an insert that includes several tips that by tightening the screw penetrate the insulating material to the conductor core.
  • FA-2 459 560 describes a device according to the preamble of claim 1.
  • the object of the present invention is a easy to manufacture and reliable connection device propose in which an undesirable damage to the Conductor core after or during attachment is avoidable.
  • the invention relates to a connection device for insulated electrical conductors that penetrate the conductor insulation and thereby making contact with the conductor core, with a Screw terminal consisting of a sleeve or socket and an in this screw consists of, the sleeve or Bushing includes at least one cutting edge or tip which when tightening the screw through the insulating material penetrates to the conductor's soul.
  • the screw terminal with sleeve or socket and at least one cutting edge or tip configured in this way is that in the area of a penetration of the cutting edge or tip in the insulating material of the conductor Notch spot on the ladder section coming from outside follows, the conductor core does not open when fastened Bending is resilient, as is free from the outside movable conductor core at the notch regularly the case is. This measure ensures that the Ladder core not susceptible to breakage due to the notch is.
  • a first embodiment of the invention consists in that the conductor is attached on both sides of one Notch location on a bearing the cutting edge or tip PCB and on the side opposite the notch comes to rest on one leg of a pressure bracket.
  • a socket of essentially rectangular cross-section whose screw is perpendicular to the narrow walls with a Pressure bracket is made of a resilient material, contains a board perpendicular to the screw, which is attached to the Pressure bracket facing side a transverse to the socket axis has running cutting edge.
  • the cutting edge is especially a sharp, preferably prismatic rib. This extends tangentially to the conductor. She presses the Insulation material locally. On the opposite However, the conductor lies with its insulation on the side Pressure bracket. Since in this way the screwing force by means of Pressure bracket is applied and this springs, is not too fear that over time, by shrinking or flowing of the insulating material the contact pressure decreases.
  • the current is preferred passed on the board. This can also be done with the sleeve firmly and with low contact resistance or connected to it be molded on.
  • a further development of this first embodiment is aimed on a mirror-symmetrically designed connection socket two screws, two pressure brackets, two opposite Receiving openings and with a window in the side wall, the correspondingly provided with two cutting edges Circuit board has a projection on its longitudinal edge, which in the Window protrudes.
  • a second basic embodiment of the invention uses a different insert.
  • This suggestion goes from a sleeve with a substantially rectangular cross section and with a screw perpendicular to the narrow walls.
  • the insert is a pressure piece with a Cutting fork, the two tines, each with two cutting edges and has a tip pointing away from the screw. At the Tightening the screw will place the conductor between the prongs of the Cutting fork pressed.
  • the insulation material is connected to two opposite sides slit tangentially and pressed apart so that the cutting edges in the Can penetrate conductor material.
  • This second basic embodiment of the invention is suitable for a mirror-symmetrical cable connector, which is expediently designed such that the Pressure piece represents the connecting busbar, with two Provide cutting forks and fastened in an insulating housing is.
  • each cutting fork works Insulating housing guided in the screwing direction and a screw together.
  • the one made from flat material Pressure piece has a U-shaped cross section, the Cutting fork tines from projections of the bent legs are shaped.
  • the cutting fork tines essentially have one triangular outline and are relative to each Arched screw axis. This results in two of each Triangle tip away inwards, d. H. to the center plane of the sleeve towards, running cutting edges, between which the conductor like is pushed into a wedge slot.
  • connection device shown in Figures 1 to 3 largely corresponds to a well-known screw terminal which, surrounded by a flat insulating material housing, one represents common terminal block. Even the drawn one Embodiment is intended as a terminal block for switchgear Find use. It is about four times more natural Size shown.
  • a socket 1 with a rectangular cross section is made Flat material "wrapped" so that the upper narrow wall, in which introduced the threaded holes for the screws 2 are made up of two layers.
  • U-shaped pressure bracket 3 are with her forked upper leg split into one Neck 4 of the respective screw clipped in and thus loose connected.
  • the lower leg of the pressure bracket is in the Socket 1 in front.
  • a board 5 is inserted, which on her Top has two prismatic cutting ribs 6, which with the sharp edge of the insulating material of a conductor 7 to be able to sever.
  • the insulating housing has the socket 1 on a side wall and a coherent one on the lower narrow wall Window opening 8 on. One intervenes in this window opening Projection of the insulating material housing.
  • the board has one lateral projection 9, which in the window opening 8th intervenes. If the board 5, as drawn, on the lower Narrow wall of the socket rests, there is a clear Window opening in the socket side wall, the length of the distance between the board 5 and the doubled Narrow wall is determined.
  • FIG. 4 to 7 is also designed as a line connector Connecting device. It has two separate sleeves 10 and 11, which in cooperation with a pressure piece 12 in an insulated housing only indicated in parallel are slidably mounted. In the thickened upper narrow wall a screw 13 is screwed into the sleeves.
  • the pressure piece 12 the two sleeves along the entire length interspersed, has a U-shaped cross section, the folded legs are very short.
  • the pressure piece points two cutting forks 14, which are arranged so that they in Longitudinal center of the sleeves 10 and 11 come to rest.
  • the Cutting forks consist of two tines 15, which on the seat the bent leg strip of the pressure piece 12.
  • the cutting forks 14 are reminiscent of the shape of a bishop's hat (Mitra).
  • the approximately triangular teeth 15 are in outline arched outwards (see Fig. 6) as if the two were facing each other opposite tines from a common cylinder barrel would have been cut out. At their top 16 they have Prongs 15 the greatest mutual distance.
  • the Andes Peaks beginning inner, d. H. the associated other Tine facing cutting edges 17 approach in their Course to the pressure piece base towards each other and thus form a wedge shape into which the conductor through the Screwing action is pressed.
  • Figures 4 and 6 also show how the pressure piece 12 in the hatched insulated body is attached.
  • the folded legs of the pressure piece have an edge recess 20 in the longitudinal center, which up to Web of the pressure piece is sufficient. With the top of this web is the pressure piece on a block-like projection 21 of the Insulating body. On the other hand intervenes strip-like projection 22 into the recesses 20. There the open side of the insulating body in the built-in Position by an adjacent terminal block or Cover plate is covered, the pressure piece can move neither side.
  • the cutting ribs 6 of the board according to the first example could also be on the inside of the lower narrow wall of the 1 attached in a different way or be molded on. This could cause the device in the Make mass production cheaper.
