Abstract

An electrical crimp connector has a plurality of two armed connecting elements made of a flat resilient contact material having a central slot. The main part of each slot extends from a widened entry aperture, is bounded by sharp edges and has a width less than the thickness of the metal core of a wire so that when the wire is pushed into the slot the insulation of wire is severed so the wire contacts the connecting element. A clamping element is associated with each connecting element and has a support surface on which the connecting element is fixed. The connecting elements are interconnected in pairs and have a number of interconnected clamping elements extending around them and are combined to form a unit having wire guides. The connecting elements are adapted to be plugged in on the support strip which is releasably connected to the insulating member on both sides of longitudinally extending lines, separate wire guides being provided on the parts which are releasable from one another.

Claims

1. An electrical crimp connector for forming a connection with an insulated wire, comprising:

an insulating member formed of a plurality of interconnected clamping elements, each of said clamping elements having a slot extending downwardly from a top surface thereof to a bottom surface thereof;

a support strip releasably secured to said bottom surface of said insulating member;

a pair of connecting elements associated with each clamping element and being joined by a transverse web, each of said containing elements being flat, strip-like and resilient and being formed of an electrically conductive material, each of said connecting elements having a slot centrally disposed thereof, each of said slots having a lower portion with a width less than the diameter of an insulated wire and an entry portion having a width greater than the width of the lower portion, said lower portion of said slot having sharp edges along the sides thereof for severing insulation on said insulated wire and contacting the core of said insulated wire for gripping thereof as said insulated wire is inserted into said lower portion of said slot, each of said pairs of connecting elements being insertable into an enclosure formed in an associated clamping element;

a multipin connector disposed on said support strip and adapted to receive connecting elements of different configurations, each of said pairs of connecting elements being pluggable into said multipin connector;

a wire guide disposed on said insulating member; and

a wire guide disposed on said support strip independently of said insulating member wire guide.

2. A device according to claim 1, wherein said connecting element of each pair of connecting elements is parallel to the other one of its pair of connecting elements and forms an angle of generally 45°

with respect to an insulated wire inserted therein, and wherein each pair of connecting elements further comprises an extension projecting from its transverse web which is engageable by said multipin connector.

3. A device according to claim 1 or 2 wherein each of said pairs of connecting elements interconnected by a transverse web have on the underside thereof formed as an extension thereof a common projection having an S-shaped cross section.

7. A device according to claim 1 or 2 wherein for each pair of connecting elements there is provided one multipin connector in a chamber bounded by side walls and cross-walls of the support strip.

8. A device according to claim 1 or 2 wherein said multipin connector is formed of spaced apart longitudinal members having longitudinal slots, a transverse slot and inclined slots.

9. A device according to claim 1 wherein said support strip wire guide comprises one centrally open guide collar formed on each end face of the support strip for a bunch of outgoing wires.

10. A device according to claim 1 wherein said insulating member wire guide comprises a wire guide adapted to be covered by a cover and serving for guiding of outgoing wires, said insulating member wire guide being disposed on one side wall of the insulating member.

11. A device according to claim 10 wherein the cover is articulated to the underside of the insulating member by means of a film hinge.

12. A device according to claim 10 or 11 wherein the insulating member wire guide has ribs which bound channels for receiving outgoing wires.

13. A device according to claim 12 wherein the insulating member wire guide has two coplanar and laterally adjacent groups of ribs.

14. A device according to claim 13 wherein a continuous rib is disposed on the underside of the insulating member wire guide and the cover is articulated via the film hinge to straight parts of said continuous rib.

15. A device according to claim 14 wherein the ribs are formed at least to some extent on the cover and on the side wall of the insulating member.

16. A device according to claim 15 wherein the cover has at the top end of the ribs a press button engaging the side wall of the insulating member.

17. A device according to claim 16 wherein the cover, ribs, film hinge and insulating member form a constructional unit.

18. A device according to claim 1 wherein the support strip has securing means on each end face for assembly on a unit for receiving an array of electrical crimp connectors.

19. A device according to claim 18 wherein the securing means are in the form of a slot and a snap connection.

20. A device according to claim 1 wherein a tongue-and-groove snap connection is provided for securing the insulating member releasably to the support strip.

21. A device according to claim 1 and 2 wherein the multipin connector is formed on an inside of the support strip facing said insulating member.

22. A device according to claim 2 or 4 wherein said multipin connector is formed on an inside surface of said support strip facing said insulating memeber.

23. A device according to claim 8 wherein said multipin connector is formed on an inside surface of said support strip facing said insulating member.

24. A device according to claim 12 wherein said ribs are formed on said cover.

25. A device according to claim 12 wherein said ribs are formed on said side wall of said insulating member.

4. An electrical crimp connector for forming a connection with an insulated wire, comprising:

an insulating member formed of a plurality of interconnected clamping elements, each of said clamping elements having a slot extending downwardly from a top surface thereof to a bottom surface thereof;

a support strip releasably secured to said bottom surface of said insulating member;

a pair of connecting elements associated with each clamping element, each of said connecting elements being flat, strip-like resilient and being formed of an electrically conductive material, each of said connecting elements having a slot centrally disposed thereof, each of said slots having a lower portion with a width less than the diameter of an insulated wire and an entry portion having a width greater than the width of said lower portion, said lower portion of said slot having sharp edges along the sides thereof for severing insulation on said insulated wire and contacting the core of said insulated wire for gripping thereof as said insulated wire is inserted into said lower portion of said slot, each of said connecting elements being insertable into an enclosure formed in an associated clamping element;

a multipin connector disposed on said support strip and adapted to receive connecting elements of different configurations, each of said connecting elements being pluggable into said multipin connector;

a wire guide disposed on said insulating member;

a wire guide disposed on said support strip independently of said insulating member wire guide; and

a spring formed on each of said connecting elements and being disposed at an angle with respect to its associated connecting element, each of said springs having a contact, said contact of said spring of one connecting element of each pair of connecting elements being normally in electrical connection with said contact of said spring of the other connecting element of each pair of connecting elements to form an openable, normally closed contact, each of said springs having an extension for engagement in said multipin connector.

5. A device according to claim 4 wherein said normally closed contacts and their springs are openable by means of a separating plug.
