Definitions
- the invention relates to an insulation displacement terminal for connection of insulated electrical jumper wires with at least one between at least two parallel to each other Clamping legs and clamping slits, which are formed on the two clamping legs.
- Such an insulation displacement connector is described, for example, by DE 88 04 388 U1 became known. Then limit the facing each other Inner edges of the clamping leg the clamping slot.
- the Clamp legs are angled along the clamp slot provided, whereby the inner edges from the plane of the clamping leg be bent out. By twisting the inner edges this creates a sharp-edged contact with the jumper wire, which makes it easier to cut the insulation. Indeed the core of the jumper wire can also be scored so strongly that the risk of breakage increases.
- the invention has for its object a cutting clamp to create where the increasingly harder jumper wire insulation securely cut and notching the Jumper wire is prevented and slipping out the wires are difficult.
- the insulation piercing is now in one Cutting area and a contact area divided, wherein in Cutting area, the inner edges are at an angle to each other and have a sharp edge on the jumper wire.
- the inner edges of the clamping legs are parallel to each other and lie flat on the core of the jumper wire.
- the harmful notching is avoided and the risk of breakage decreased.
- Due to the shear cut the bends form against the Clamping zone has a sharp-edged projection that goes into the movement path of the insulated jumper wire protrudes and the one accidental emergence of the pressed wire the clamping zone considerably more difficult.
- the bends are directly opposite each other, creating isolation is cut evenly.
- the training according to claim 3 the isolation incised places of the jumper wire.
- the clamping edges of the clamping legs are between the two bends, which makes the incisions better on Center the clamping edges.
- an insulation displacement connector 1 has two mutually parallel clamping leg 2, between which a Clamping slot 3 is formed.
- the two clamping legs 2 are integral with each other at a foot end, not shown connected and can e.g. by an indented one Jumper wire are spread apart so far that they are resilient are braced against each other.
- bevels 4 that are V-shaped to each other are inclined.
- the inlet slopes 4 are along a Bending axis 5, which is parallel to the bevel 4 extends from the material level of the insulation piercing 1 into the bent out the same direction and thus form 2 sharp edges opposite cutting edges 6, on which the insulation of an indented jumper wire cut without difficulty can be.
- the insulation displacement connector 1 is thereby in an inlet area and divides a clamping area, which directly adjusts to Connects inlet area with the separating slot 3, wherein the bends 7 of the inlet slopes 4 are separated from a clamping zone of the clamping legs 2 by a shear cut 8.
- the Cutting edges 6 cut the when pressing the jumper wire Isolation like a knife. When pushing the Jumper wire press the inner edges of the clamping slot 3 in the incision, which creates the isolation is pushed further apart and the clamping leg be securely contacted with the core of the jumper wire.
- the two bends are 4 in opposite directions from the material plane bent out.
- the clamping edges of the clamping legs are now there 2 offset in the middle between the two Cutting edges 6 so that they are better on the resulting Center the incision of the insulation.
- Figure 5 are the two clamping legs 2 by about half the material thickness offset from each other. Dislocations and angling are directed in opposite directions. Thereby the distance between the two cutting edges 6 is considerable reduced so that the incision and contact is relieved accordingly.
