Definitions
- the invention relates to an insulation displacement connector for contacting the non-stripped end of an electrical conductor with the features of the preamble of claim 1.
- a clamping slot is formed between two contact limbs, the mutually facing cutting edges of which run parallel to one another. Due to the resilient contact material, two conductors with different diameters can be clamped in the contact area for double contacting. However, the diameter range of the conductors to be contacted is limited due to the geometry of the clamping slot forming the contact area.
- EP 0 274 948 AI also discloses an insulation displacement connector with a V-shaped contact area.
- the contact area is set up in a circular arc due to its cutting edges.
- the cutting legs are rigid and have no clamping effect.
- the conductor is inserted by being pressed in in the tapering direction of the V-shaped insertion region, the mutually facing cutting edges of the cutting legs penetrate the conductor insulation up to the conductor core.
- the conductor is clamped in the contact area by means of a lever arm.
- the invention has for its object to provide an insulation displacement terminal of the type mentioned that the contacting of electrical conductors over a large without stripping Conductor cross section area enabled.
- Conductor cross sections between about 0.5 and 2.5 mm 2 are intended.
- Both solid and finely stranded electrical conductors should be able to be contacted here.
- a high pull-out strength comparable to that of a screw terminal should be guaranteed.
- the insulation displacement clamp should be operable with a simple tool, for example a screwdriver, both during assembly and disassembly.
- the clamp expediently consists of bimetal (claim 9). It advantageously results from a single, one-piece bimetal blank. This will e.g. the elasticity of steel combined with the conductivity of aluminum.
- the inventive design of the insulation displacement clamp causes the exact opposite when heated by a large current density at the contact point or at the contact points instead of a decrease in the contact pressure and a further increase in the contact resistance associated therewith. This is because the different coefficients of thermal expansion of the elements of the bimetal, that is to say bimetal effects, are usefully exploited.
- the conductor itself provides a specific stop, which can be used in several ways. This is possible once in the version as a "moving insulation displacement", in which the conductor is inserted or placed in or on a receptacle and the insulation displacement contact is moved relative to the conductor.
- a second connection which serves only for clamping can be used according to claim 12 to a further conductor part, for example to a switching contact of a command device.
- the action of the pliers can be controlled by the head depending on the position. This is possible via the contour of the conductor part and / or the terminals or the surrounding housing.
- a version as a "fixed insulation displacement terminal” can also be implemented, in which the conductor lies in a guide element, for example a plastic part, and is displaced in the terminal.
- the tension of the insulation displacement terminal may be dependent on the The displacement path of the conductor and thus the outside diameter of the conductor can be changed, and further features of the insulation displacement clamp which favor resilient pliers action are set out in claims 13-16.

- FIG. 2 shows a perspective detailed view of the area of the insulation displacement clamp
- FIG. 3 shows a vertical section along the central longitudinal plane of the insulation displacement clamp according to FIG. 1 from a different direction and FIG. 3 shows a vertical section along the central longitudinal plane of the insulation displacement clamp according to FIG. 1 from a different direction and FIG. 3 shows a vertical section along the central longitudinal plane of the insulation displacement clamp according to FIG. 1 from a different direction and FIG. 3 shows a vertical section along the central longitudinal plane of the insulation displacement clamp according to FIG. 1 from a different direction and FIG. 3 shows a vertical section along the central longitudinal plane of the insulation displacement clamp according to FIG. 1 from a different direction and FIG. 3 shows a vertical section along the central longitudinal plane of the insulation displacement clamp according to FIG. 1 from a different direction and FIG. 3 shows a vertical section along the central longitudinal plane of the insulation displacement clamp according to FIG. 1 from a different direction and FIG. 3 shows a vertical section along the central longitudinal plane of the insulation displacement clamp according to FIG. 1 from a different direction and FIG. 3 shows a vertical section along the central longitudinal plane of the insulation displacement clamp according to FIG.
- Insulation displacement clamp in viewing direction III-III of FIG. 1.
- the insulation displacement terminal contains, for contacting the non-stripped end of an electrical conductor, not shown, two contact legs 3, 4 facing one another with their side edges 1, 2, which include between them an insulation displacement gap 5 with the outline shape of an upside-down Y, for example.
- the head edges 7, 8 of the Y shape which stand up to one another in an upside-down V shape and delimit the insertion opening 6, form a cutting area which penetrates the conductor insulation.
- the head antennas 7,8 of the insertion opening 6 or the Y-shape are corrugated in the longitudinal direction in the manner of cutting a household knife.
- the mutually facing end faces 11, 12 of the head edges 7, 8 are chamfered in such a way that they form an acute-angled cutting edge 14, 15 on their inside facing the receiving space 13 for the conductor end.
- Each cutting edge 14, 15 thereby forms a positive clearance angle with the adjacent end face 11 and 12, and thus with its outside 16 and 17, respectively, withdrawing from the insertion opening 6.
- the contact legs 3, 4 are approximately in the area of the cutting edges 14, 15 Level. In the area of their base edges forming the clamping contacts, the contact legs 3, 4 with their contacting end faces 18, 19 face the receiving space 13 for the conductor end. As a result, they form an outwardly opening angle 22 with their outer surfaces 20, 21.
- the plane delimited by the contact limbs 3, 4 in the area of the cutting edges 14, 15 and containing the insertion opening 6 is inclined outwards towards the side facing away from the receiving space 13 for the conductor end to form an obtuse angle 23 with the clamping contact area 24.
- the receiving space 13 for the conductor end has a contact stop for the insulation-free conductor end on its side facing away from the contact limbs 3, 4. In the exemplary embodiment, this contact stop is formed by at least one of the two clamping contact jaws 28, 29 which enclose a clamping contact slot between them.
- the insulation piercing consists of a one-piece bimetal blank. It is formed by a U-shaped base body surrounding the receiving space 13 for the conductor end, the U legs 30, 31 of which form the side walls of the base body.
- the contact legs 3, 4 are integrally formed on one side edge of each of the two side walls, in the case of FIGS. 1-3 on their front side edge.
- the other, in the FIG rear side edge carries a clamping contact jaw 28 and 29, respectively.
- the bottom web 32 as a U-web forms together with the U-legs 30, 31 the U-shape of the base body.
- This U-shape of the base body is developed by a lock 33 of the free ends of the U-legs 30, 31 opposite the U-web 32 to form a frame surrounding the receiving space 13 for the conductor end.
- This lock 33 is articulated by a swivel disk 35 engaging in a swivel recess 34 such that a certain mobility of the U-legs 30, 31 against one another is possible. This mobility is further supported by an elastic design of the U-web 32 between the two U-legs 30, 31.
- a non-stripped conductor is shifted with its cut end transversely to its longitudinal direction in the direction of the arrow of the insertion opening 6.
- the conductor end projects into the receiving space 13 and against a contact stop in the form of, for example, at least one of the two clamping contact jaws 28, 29.
- the end of the conductor is inserted into the insertion opening 6 (FIG. 2), the end of the conductor is guided in a ribbing which runs approximately parallel to the longitudinal direction of the U-legs device against the insulation displacement gap 5 and thereby pushed into it.
- the insulation of the conductor is not only cut through by the inclination of the leading edges 7, 8 spanning the insertion opening 6 or the cutting edges 14, 15 formed by the leading edges 7, 8.
- the conductor continues to be acted upon in the direction of the clamping contact jaws 28, 29.
- the contact limbs 13, 4 spring apart apart as a result of spreading open, thereby allowing the ablated conductor to be inserted into the clamping gap 5 of the clamping contact area 24, where it is secure due to the elastic clamping pressure and, in part, also due to slight notching on the part of the contact limbs 3, 4 is held.
