Definitions
- Insulation displacement clamp for connecting insulated electrical jumper wires
- the invention relates to an insulation piercing terminal for connecting insulated electrical jumper wires with at least one clamping slot formed between at least two mutually parallel clamping legs and lead-in bevels which are formed on the two clamping legs.
- Such an insulation displacement connector is known for example from DE 88 04 388 Ul.
- the mutually facing inner edges of the clamping limbs then limit the clamping slot.
- the clamping legs are provided with bends along the clamping slot, as a result of which the inner edges are bent out of the plane of the clamping legs.
- the twisting of the inner edges creates a sharp-edged contact with the switching wire, which makes it easier to cut the insulation.
- the core of the jumper wire can also be indented so much that the risk of breakage increases.
- the object of the invention is to create an insulation displacement terminal in which the increasingly harder jumper wire insulation is securely cut in and the notching of the jumper wire wire is prevented.
- the invention now divides the insulation displacement terminal into a cutting region and a contact region, the inner edges in the cutting region being at an angle to one another and having a sharp edge on the switching wire.
- the inner edges of the clamping legs are parallel to each other and therefore lie flat against the core of the jumper wire. The harmful notching is avoided and the risk of breakage is reduced.
- the bends form a sharp-edged projection with respect to the clamping zone, which makes it considerably more difficult for the pressed-in contact wire to come out of the clamping zone unintentionally.
- the bends are directly opposite one another, as a result of which the insulation is cut uniformly.
- the insulation is cut at points of the jumper wire which are offset from one another.
- the clamping edges of the clamping legs lie between the two bends, as a result of which the cuts center better on the clamping edges.
- the switching wire core is clamped symmetrically between the two clamping legs, wherein a bending element acting on the switching wire is avoided.
- FIG. 1 shows a side view of a cutting clamp with two clamping legs and a run-in slope
- FIG. 2 shows another side view of the cutting clamp according to FIG. 1
- FIG. 3 shows a top view of the cutting clamp according to FIG. 1
- FIG. 4 shows a top view of another cutting clamp with oppositely bent-out angles in the insertion Running area and mutually aligned clamping legs
- FIG. 5 is a plan view of another insulation piercing similar to FIG. 4, but with clamping legs arranged offset from one another.
- an insulation displacement clamp 1 has two mutually parallel clamping legs 2, between which a clamping slot 3 is formed.
- the two clamping legs 2 are integrally connected to one another at a foot end (not shown) and can e.g. are spread apart so far by a pressed-in jumper wire that they are resiliently braced against one another.
- the clamping limbs 2 form inlet bevels 4 at their free end, which are inclined to one another in a V-shape.
- run-in bevels 4 are bent along a bending axis 5, which extends parallel to the run-in bevels 4, out of the material plane of the insulation piercing clamp 1 in the same direction and thus form 2 sharp-edged opposite cutting edges 6, on which the insulation of a pressed-in contact wire without Difficulties can be cut.
- the insulation displacement connection 1 is thereby divided into an inlet area and a clamping area, which directly adjoins the inlet area with the separating slot 3.
- the cutting edges 6 cut the insulation like a knife when pressing the jumper wire.
- the inner edges of the clamping slot press 3 into the incision created, which pushes the insulation further apart and the clamping legs are securely contacted with the core of the jumper wire.
- the parallel parallel clamping legs 2 then clamp the jumper wire at diametrically opposite positions in one plane, without causing a notch in the jumper wire core.
- the angled portions 4 protruding from the plane of the clamping legs 2 also prevent the jumper wire from being pulled out of the clamping slot 3 without the application of greater force.
- the two bends 4 are bent out of the material plane in opposite directions.
- the clamping edges of the clamping legs 2 now lie in the middle between the two mutually offset cutting edges 6, so that they can be centered better on the incision made in the insulation.
- the two clamping legs 2 are offset from one another by approximately half the material thickness. The dislocations and the bends are directed in opposite directions. As a result, the distance between the two cutting edges 6 is considerably reduced, so that the cutting and contacting is correspondingly facilitated.
