Definitions
- the invention relates to a contact element for the 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.
- a contact element with a contact knife which has a slot provided with a cutting edge and open at one entry end.
- the conductor is pushed into the slot from the entry end.
- the isolation also works cut open.
- two longitudinal slots are made in the contact element on both sides of the slot at a distance therefrom and parallel to it.
- DE-A-35 22 112 describes one of a flat
- Sheet piece formed contact element with a slot delimited by cutting and clamping edges.
- the contact element is provided with an opening similar to a keyhole.
- the round opening part of this opening is dimensioned such that a conductor to be contacted can be inserted through it.
- the slot-shaped opening part forms the slot for contacting.
- 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-A-0 176 861 shows a contact element designed as a slotted cylinder.
- the contact element contains an elongated sleeve section with a longitudinal slot which receives a conductor to be contacted.
- a lateral groove with a section of reduced width is provided to secure the conductor.
- 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 clamp with a U-shaped sheet metal part, in which funnel-shaped cut-outs and adjoining slots extend from the U-bend provided with an opening into the legs and accommodate a conductor, is described in DE-A-31 08 931 .
- the conductor sits in a bore in a block-like body which is provided with slots and is pushed over the sheet metal part, a central part protruding through the opening between the legs of the sheet metal part.
- the block-like body snaps into two positions in a base body carrying the sheet metal part. In the outer position the conductor can be threaded into the hole, in the inner position the conductor is pressed into the slots of the terminal by the block.
- the invention has for its object to provide a contact element of the type mentioned in such a way that the conductor can be inserted manually into the slot in a simple manner.
- 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. But it can also be in an insulating body with an im
- the contact member can then be a at the held end following the part bearing against the guide surface
- 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 material that forms a cavity. In the cavity of the Isol iers ⁇ offêt stresses a sheet metal part can sit, which forms at least one contact knife. The sheet metal part forms the pocket in the insulating body. The contact knife sits on a side wall of this pocket, which bears 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 contact knife can form a cutting jaw z ⁇ m cutting into the insulation at the entry end of the slot. It can also be provided in all embodiments of the invention along the slot notches, in which an increased resistance can be felt when the conductor is retracted. These notches can be represented by changes in the direction of the slot. The change of direction does not only have to take place in the plane of a flat contact knife. Rather, the contact knife can also be a multi-fold sheet metal strip, so that the change in direction of the slot takes place by kinking the sheet metal strip. In order to enable an optional detachment of the conductor from the contact element, the slot at its end opposite the entry end can have an exit end that allows the conductor to be pulled out.
- This exit end can consist in that the slot is made continuously.
- the slot can also end in an extension that allows the conductor with its insulation to pass through.
- the invention also includes 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 inlet end , cutting through the insulation and contacting the metallic core with the edges of the slot,
