Definitions

  • the invention relates to a connection device for at least one electrical conductor that is a line wire and has insulation, with a connector that two opposing contact blades with cutting edges for cutting through the insulation.
  • a generic connection device is from the document EP 0 511 098 B1 is known.
  • This includes a metallic one Limb that is set in a space of a housing and the at least one connection unit with a convex hexagonal shape and with a slit along one of its forms diagonal levels.
  • the slot is used to hold the Wire and cut through the insulation to finally to contact the wire.
  • the slot has one extended mouth to cut through the insulation of the Wires with cutting edges.
  • the insulation displacement contact has a contact mouth with a flat to oval shape Narrow sides as well as cutting and contact surfaces.
  • the contact mouth is made from converging inner surfaces of Contact fingers formed. One pressed into the contact mouth or drawn wire opens the contact fingers to the wire diameter corresponding. Cut further after pressing in the cutting the insulation of the wire strand and hit then peripheral to the wire.
  • the NL-PS 67298 discloses insulation displacement contacts, the contact cutting extending in contact with the cutting edges expand.
  • the invention has for its object a connection device of the above type to create the simple Way of contacting conductors of different diameters made possible regardless of the insulation material and thereby for solid, fine and multi-wire conductor cross-sections suitable is.
  • the object is achieved by that the contact cutting edge is in extension expand the cutting edges to contact surfaces that after connecting the line aligned transversely to the line axis are.
  • a particularly advantageous embodiment exists according to claim 2 when the contact cutting between the cutting edges and the contacting areas an expansion area to expand the insulation through the cutting edges have formed slot. With one operation thus a large-area contact with the cable core to reach.
  • a particularly simple embodiment is when the Expansion area is formed by inclined surfaces that are connect the edge surfaces forming the cutting edges.
  • connection process is facilitated by a pressure piece with a slot adapted to receive the contact blades and with an opening for receiving the conductor, whose im Area of the slot lying after insertion into the opening Section by means of contact cutting by pressing is contactable between them.
  • connection of several conductors can be particularly advantageous be realized if a one-piece connector with one or more cages is used.
  • the connecting device is advantageously a component a device, with several connecting parts each in one Chamber of the device are held and attached to each connector pressure piece attached captively to the device is provided, with which at least one conductor can be connected and connected Condition is lockable.
  • connection device 1 shows a connection device according to the invention in the open State in which two non-stripped round conductor 1 for Preparation of the connection are introduced.
  • the connection device consists essentially of a connecting part 2, which is fixedly mounted in a chamber of a housing 3, and from a movable pressure piece 4, which on the outside of the Housing 3 is accessible. With the connector 2 is one Busbar 5 connected.
  • connection devices according to FIG 1 in an electrical device 6 in which a variety of Terminals for the electrically conductive connection between outer conductors 1 and electrical components inside the Device 6 are determined.
  • the connection of lines 1 is by actuating pressure pieces 4 by means of a screwdriver possible.
  • FIG 3 is a one-piece connector 2 with two cages 7 shown, each at their narrow ends as Contact cutting 8 are formed.
  • the connector 2 is by punching, by squeezing the narrow end areas to contact cutting 8 and then by bending Cages 7 can be produced in a simple manner.
  • To connect one Conductor 1 is provided with a pair of contact blades 8, which together an enlarged mouth 9 for insertion of the respective conductor 1 form.
  • On the contact blades 8 opposite side is the connector 2 for further connection provided with the busbar 5.
  • the connector 2 3 has two superimposed cages 7 for contacting two round conductors 1.
  • the trained according to FIG 4 Contact cutting edges 8 have a triangular shape that Mouth 9 forming surface 19 provided which in a Cutting edge 10 passes over. In extension to this a contacting surface 11, the transition from the Cutting edge 10 to the contact surface 11 as a widening area 17 is formed with inclined surfaces 12, which are the connect the cutting edges 10 forming edge surfaces 13.
  • the contact surfaces 11 of the contact blades arranged in pairs 8 are parallel to each other and are transverse to Line axis of the connected conductor 1 aligned, see above that there is extensive contact with the line wire of an inserted conductor 1 results.
  • FIG 5 shows a front view of the connecting part 2 according to FIG 3, a plan view of the connecting part 2 is in FIG 7 and a sectional view of the same shown in FIG 8.
  • the pressure piece 4 of the connection device is in shown a perspective view. It has one Slot 18 for receiving the contact blades 8 of a connecting part 2 and has two openings 14 for enclosing two lines.
  • the pressure piece 4 is in the open connection state 1 and 2 inserted into the cages 7 in such a way that the openings 14 above the enlarged mouths 9th lie, i.e. in this state, lines 1 are in the openings 14 insertable.
  • the pressure piece 4 has an operating surface, that with a recording, e.g. Phillips, for engagement a screwdriver is provided with the Pressure contacting conductors 1 can be carried out.
  • FIG. 9 shows a plan view of the pressure piece 4 and FIG. 10 a sectional view of a section according to FIG. 9.
  • the conductor 1 arrives in the widening area adjoining the cutting edges 10 17, in which the slot in the insulation is widened, so that the wire of the round conductor 1 is partially exposed and with the adjacent contact surface 11 a flat one Can touch.
  • the Connection part 2 can be via a Connecting device several conductors 1 by means of a pressure piece 4 can be connected. This is advantageous Pressure piece 4 both in the open connection state and in closed state lockable, i.e. the pressure piece 4 is attached captively.
