Definitions

  • the invention relates to a contact element for tool-free contacting of insulated electrical conductors, which consist of a conductive metallic core and an insulation surrounding it, with a contact knife having a slot provided with a cutting edge, into which the insulated electrical conductor can be moved at an inlet end , cutting through the insulation and contacting the metallic core with the edges of the slot.
  • DE-A-31 16 731 describes a contact element punched out of a thin sheet metal strip for connecting electrical conductors to one another.
  • the contact element has cutouts through which resilient legs are formed which enclose a slot between them. By cutting, which are provided on the resilient legs, the insulation of the conductor is cut so that the legs come to rest on the metallic core of the conductor. To achieve high cutting and clamping forces, a spring clip is molded onto the contact element. Two wires to be connected are pressed into the slot of the contact element.
  • DE-B-26 21 703 relates to a contact body made of flat material with two fingers which delimit a slot therebetween. The fingers are twisted in the opposite sense, the twist gradually decreasing from the free end to the base end. This is not a contact element for contacting insulated conductors, it is a contact for switches.
  • EP-B-0 101 290 shows a contact element with several slots for contacting several insulated conductors.
  • the slots are provided in the legs of a U-shaped sheet metal part.
  • a contact element which enables a simplified insertion of a conductor is known from US-A-4 194 802.
  • the invention can be implemented in various ways.
  • the wire support means can have a concavely curved guide surface, through which the conductor is guided through the plane of the contact knife past the entry end of the slot.
  • the guide surface can be a surface on an insulating material part that is curved in a longitudinal section in a U-shape.
  • the contact knife can then be arranged with its entry end in front of this contact surface, so that a passage opening, delimited by the guide surface, is formed for the conductor.
  • the contact element has a bent metal body which forms in its curved part a groove open to the inside of the curvature, and one end of the bent metal body is tubular and provided with a longitudinal slot and forms the contact knife.
  • tubular is not restricted to a circular cross section.
  • the tubular end may well be other, e.g. rectangular, cross-section.
  • a stop is provided on the trough-shaped part of the contact element, which limits the insertion movement of the conductor. This ensures that the conductor can only be inserted to the extent that it can also be pulled out of the slot if necessary.
  • a further embodiment of the invention is that the wire support means form a pocket, the contact knife sits in a side wall of this pocket and the slot of the contact knife is open towards the open end of the pocket, the conductor being inserted into the pocket from its open end and then pulled into said slot towards said side wall while the end of the conductor is supported on the side wall opposite this side wall.
  • the wire support means have an insulating body that forms a cavity.
  • a sheet metal molded part, which forms at least one contact knife, can sit in the cavity of the insulating material body.
  • the sheet metal part forms the pocket in the insulating body.
  • the contact knife sits on a side wall of this pocket, which rests against a side wall of the insulating body.
  • the side wall of the insulating material body has a slot aligned with the slot of the contact knife.
  • a single sheet metal body can form a plurality of pockets, each with a contact knife, in the insulating material body.
  • the invention also encompasses a method for contacting insulated electrical conductors, which consist of a conductive metallic core and an insulation surrounding it, with a contact knife which has a slot provided with a cutting edge, into which the insulated electrical conductor can be moved at an entry end , cutting through the insulation and contacting the metallic core with the edges of the slot,
  • An insulated conductor 52 is pushed in the direction of arrow 54 against the concave guide surface 20 and deflected by the latter.
  • the conductor 52 lies against the guide surface 20.
  • the toric shape of the guide surface 20 helps to hold the conductor 52 essentially in the vertical central plane of the guide surface in FIG.
  • the conductor is guided through the opening 34 and deflected forward again below the contact knife 26 in FIG.
  • a pull is then exerted on the insulated conductor 52 in the direction of the arrow 56, the conductor 52 reaching the position 58 shown in broken lines in FIG.
  • the front end 60 of the insulated conductor 52 is supported on the lower part of the guide surface 20. This makes it possible to pull the insulated conductor 52 into the slot 38.
  • the insulation of the insulated conductor 52 is cut through to the metallic core 62 by the cutting jaw 40.
  • the surface of the core 62 is also scratched, so that oxide layers on this surface are cut through.
  • the edges 42 and 44 of the slot 38 resiliently bear against the metallic core 62 of the conductor 52 through the cuts in the insulation.
  • the conductor 52 is then drawn into the slot 38 until a "catch" is reached, ie a point 46 at which the direction of the slot 38 changes.
  • a "catch" is reached, ie a point 46 at which the direction of the slot 38 changes.
  • the user initially feels an increased drag. This signals that the conductor is securely drawn into slot 38 and prevents the conductor 52 from being unintentionally pulled out of the slot.
  • two such catches are provided one behind the other in points 46 and 48.
  • the conductor is then passed through the opening 50 for strain relief, as shown in broken lines at 64.
  • the conductor 52 is to be detached again from the contact knife 26, then after the conductor 52 has been pulled out of the opening 50, the conductor 52 is pulled out further forward in the direction of the arrow 56 via the points 46 and 48 from the slot 38.
  • 66 is an insulating body.
  • the insulating material body 66 has a flat cuboid shape and has a recess 70 from an end face 68.
  • the recess 70 is delimited by side walls 72, 74.
  • the recess 70 initially has a flat wall part 76 at the bottom in FIGS. 2 and 3.
  • a semi-cylindrical wall part 78 adjoins this flat wall part 76.
  • an opening 80 extending up to the end face 68 is provided in the insulating material body 66.
  • the wall of the insulating material body 66 is thickened on both sides of the flat wall part 76. In the thickened parts 82 and 84, opposing grooves 86 and 88 are provided along the plane wall part 76 but at a distance from it.
  • a spring steel strip 90 is guided in the grooves 86 and 88. This end forms a contact knife 92 of the type described in connection with FIG. 1.
  • the spring metal strip 90 lies against the upper part of the semi-cylindrical surface 78 and is then guided to the grooves 86, 88 with the formation of an intermediate space 94.
  • the spring steel strip 90 has an opening 96 in the area of the intermediate space 94.
  • a slot 98 of the contact blade 92 connects to the opening 96.
  • the slot 98 is open towards the end of the spring steel strip 90.
  • the slot 98 like the slot 38 of FIG. 1, is provided with a cutting mouth and notches.
  • the opposite end 100 in FIG. 2 here forms a resilient contact tongue which projects into the opening 80.
  • a conductor to be contacted is inserted similarly to the embodiment according to FIG. 1 and is guided through the inner surface of the spring-metal strip 90. The conductor then passes through the opening 96 into the intermediate space 94. There, the front end of the conductor is further guided and supported by the semi-cylindrical surface 78. By pulling the conductor, the conductor is then pulled into the slot 98 of the contact knife 92.
  • the contact element is a J-shaped metal body 102.
  • a guide surface is formed by a groove 104, which represents the arc of the "J".
  • the metal body 102 forms a slotted tube.
  • This slotted tube forms on its upper side in FIG. 4 a contact knife 108 (FIG. 5).
  • the contact knife 108 has a continuous slot 110.
  • a cutting jaw 112 is formed at the entry end of the slot 110.
  • Latches 114 are provided along slot 110. In the embodiment according to FIG. 5, these notches 114 are formed by roughened sections of the edges 116 and 118 of the slot 110.
  • Contacts 120, 122, 124 and 126 are attached to the metal body 102 for soldering or other connection of further conductors.
  • the insulated conductor 128 is inserted in the direction of the arrow 130 into the straight section 106 of the J-shaped geogenous metal body 102 formed by a slotted tube.
  • the conductor is deflected through the inner wall of the channel 104 and also bent in a J-shape.
  • the front end of the conductor finally abuts a stop 135 formed in the groove 104. This ensures that the conductor 128 is inserted into the metal body to a defined length and is bent to a defined shape.
  • the conductor 128 is drawn into the slot 110 of the contact knife 108, as indicated by dashed lines at 134.
  • the conductor 128 is drawn into the slot 110 until an increased resistance can be felt through a roughened section 114 of the edges 116, 118. Overcoming this resistance with increased tensile force, the conductor 128 can be pulled out of the slot 110 to the right in FIGS. 4 and 5 if necessary
  • the wire support means have a pot-shaped insulating material body 140 with an essentially square cross section.
  • the insulating body 140 forms a cavity 148.
  • the edge 144 at the open end of the cup-shaped insulating body 140 is drawn inwards.
  • slots 150 and 152 are made up to approximately half its height.
  • the slots 150 and 152 allow the upper part of the insulating body 140, which is upper in FIGS. 6 to 8, to be bent apart somewhat resiliently.
  • incisions 158 and 160 are provided from the edge 144, incisions 158 and 160 with sawtooth-shaped edges extending along the central plane perpendicular to the side surfaces 154, 156.

  • a cutting jaw 176 is again formed at the entry end of the slot.
  • closed longitudinal slots 178 and 180 are provided at both ends, which are divided by webs. These longitudinal slots each form an angle with the slot 172 so that they diverge towards the entry side of the slot 172. Resilient webs are thus formed between the edges of the slot 172 and the longitudinal slots 178 and 180, the width of which increases towards the entry side. A substantially constant clamping force is thereby obtained over the entire length of the slot 172.
  • the division of the longitudinal slots 178 and 180 increases the stability.
  • the slots 172 of the contact blades 170 lie inward from the slots 158 and 160 of the insulating material body 140 and are aligned therewith.

  • the inner wall of the pocket 184 opposite the contact knife 170 used in each case supports the end of the conductor 186, so that it cannot escape and it is possible to pull the conductor 186 into the slots 172 and 160 of the contact knife 170 or of the insulating material body 140.
  • more than two insulated conductors can be contacted with a common sheet metal part and thus electrically connected to one another. There are separate pockets for different conductors.
