Abstract
An insulation piercing electrical connector (20) includes a plurality of insulation piercing projections (38) which engage and secure the conductor (14) in compressive electrical contact. The insulation piercing projections (38) extend from resiliently deformable cantilevered contact arms (34) which are deflectable into contact with an insulated wire (14). A plurality of intersecting slots (44) are formed by the insulation piercing projections (38) which compressively secure the conductor (14) therein.
Description
- The invention relates generally to insulation piercing electrical terminals for insulated wire and more particularly to an electrical terminal having insulation piercing projections for contacting the conductor of the wire and compressively retaining the conductor therein.
- The use of insulation piercing and insulation displacing contacts is widespread in the electrical wire terminating industry. The advantage of such contacts is that insulated wire need not be stripped of the insulation prior to termination. This of course saves both installation time and expense as no stripping tools need be employed.
- Most of the insulation displacing contacts (I.D.C.) used today are of the "U"-shaped or forked variety, having a pair of upwardly extending tines which form therebetween a slot for receipt of the insulated wire. These IDC's make contact along the internal marginal edges of the slot, with the tines acting as pre-loaded cantilevered beams which deflect slightly outwardly upon insertion of the wire into the slot. These "U"-shaped IDC's thus spread open to receive the wire, pierce the insulation and electrically contact the conductor.
- While this technique has proven successful in many applications, it does have certain disadvantages. As the wire is inserted between spreading tines the conductor, upon termination will be seated between the spreading tines. In time, such connection may tend to become loose and the electrical continuity may be intermittent. This problem is especially prevalent when terminating stranded wire as the strands have a tendency upon termination, to move outwardly away from the bottom portion of the U-shaped contact toward the wider portion of the spreading tines. Thus, the strands may not be adequately electrically engaged in the slot.
- The use of U-shaped or forked terminals is well known for terminating solid conductor wire. Examples of these connectors are shown in U.S. Patent No. 3,117,829 issued on January 14, 1964 and in U.S. Patent No. 3,058,088 issued on October 9, 1962. As can be seen in these references the "U"-shaped contact engages the cable at substantially 90° and spans the diameter thereof. The tines then deform in some manner to accommodate the solid conductor therebetween
- Other insulation displacing terminals are known to employ a plurality of radially extending cantilevered contacts which contact the conductor at plural locations. Such contacts are shown in U.K. Patent Specification 1,109,914, French Patent 1,312,525 and German Patent 468,535. These terminals have cantilevered members with IDC end portions, which are designed to pierce only partially into the cable and make conductive contact with the conductor. However as the contacts do not substantially extend into the conductor region of the cable, there is only minimal surface contact with the conductor.
- It is an object of the present invention to provide an insulation displacing terminal having contact members which pierce the wire insulation and contact the conductor in compressive relation, establishing an effective electrical connection therebetween.
- It is a further object to provide a series of slots, formed between the contact members, which secure the conductor therein to compress the conductor of the wire.
- In the effective attainment of these and other objects the present invention contemplates providing an electrical terminal for an insulated wire conductor which includes a plurality of insulation displacing contacts. The contacts pierce the insulation and contact the conductor. A plurality of slots are formed between the contacts which support and engage the conductor in compressive fashion, thus establishing an effective compressive electrical connection.

- Fig. 2 is the connector of Fig. 1, shown in the closed or connected position.
- Fig. 3 is a partial longitudinal sectional showing of the connected wire and connector of Fig. 2 taken along the lines III-III.
- Fig. 4 is a cross-sectional showing of the wire and the connector taken along the line IV-IV of Fig. 1.
- Fig. 5 is a cross-section of connector and wire of Fig. 2, taken along the line V-V.
- Referring to Fig. 1 a section of
electrical cable 10 is shown comprising an outerinsulative jacket 12 made of plastic or similar material, surrounding aconductor 14. The present invention terminates strandedconductors 16 which collectively formconductor 14. -
Connector 20 is a two-piece member comprising an outer housing orsleeve 22 and aconductive member 24.Sleeve 22 is an elongate hollow cylindrical structure having acentral bore 26. Sleeve 22 slidably frictionally receivesconductive member 24 as will be described in detail hereinafter. In the presentillustrative embodiment sleeve 22 is constructed of steel or similar metal, however it is also contemplated thatsleeve 22 may be constructed of a non-conductive, suitably rigid material such as glass-filled plastic or ceramic assleeve 22 need not be in conductive contact withconductive member 24. -
Conductive member 24 has an elongate body having aterminal end portion 28, a frusto-conicalcentral region 30, and a cylindrical insulation displacingcontact portion 32 at the end axially oppositeterminal end portion 28. As shown in the drawings,terminal end portion 28 is in the form of a pin for insertion into a mating socket of a similar wire connector. The present invention also contemplates forming a socket or other terminal shape in place of the pin shown in the drawings. - Insulation displacing
contact portion 32 includes fouridentical contact arms 34 which extend in cantilevered fashion from and circumferentially around acylindrical body section 36 adjacent frusto-conical region 30. Contactarms 34 are formed from cylindrical insulation displacingcontact portion 32 and are resiliently deformable.Cylindrical body section 36 as well ascantilever contact arms 34, in compressed position, have an outer diameter which is closely dimensioned to the inner diameter ofsleeve 22 to permitsleeve 22 to frictionally slide thereover. Referring additionally to Fig. 4, each of the unsupported ends of cantileveredcontact arms 34'includes a transversely extendinginsulation piercing projection 38. Referring to one of theprojections 38 as representative of the four identical projections, it can be seen thatprojection 38 is a wedge-shaped member having a pair of substantiallyperpendicular side edges insulation piercing point 42. Theremaining edge 43 of the wedge-shaped projection 42 is arcuate at the juncture withcantilevered arm 34. -
Connector 20 is connected tocable 10 by inserting a cable end 21 (Fig. 1) among the spread apart cantileveredcontact arms 34 and intocylindrical body section 36 until it abuts against the interior walls of the frusto-conical section 30. In this position,sleeve 22 is slidably moved in the direction shown by arrow A overbody section 36. Further movement ofsleeve 22 in the direction of arrow A, will forcesleeve 22 into engagement with the base of cantileveredcontact arms 34. Still further progression ofsleeve 22 will urgecontact arms 34 inwardly towardcable 10. Thepoints 42 of the fourprojections 38 will pierce theinsulative jacket 12 ofcable 10 and contact theconductor 14. As theinsulation piercing projections 38 are progressively pressed inwardly by the inward deflection ofcantilevered contact arms 34, thestrands 16 formingconductor 14 will be displaced. Initially, thestrands 16 substantially occupy the inner cross-sectional area ofcable jacket 12. Movement ofinsulation piercing projections 38 displaces the strands into an increasingly smaller cross-sectional area. As a result of such displacement thestrands 16 will be progressively compressed between the respectiveopposed side walls sleeve 22 is moved fully alongconductive member 24, adjacent theprojections 38, cantileveredcontact arms 34 will be fully deflected andprojections 38 will have fully piercedcable insulation 12 and will compressively confine thestrands 16 ofconductor 14. - Referring to Figs. 3 and 5 the resulting compressive connection is shown. In fully progressed
position sleeve 22 will lie adjacent the distal end ofconductive member 24. Theinsulation piercing projections 38, which have been radially, inwardly disposed by movement ofsleeve 22, engagestrands 16 within elongaterectangular slots 44 formed by theopposed side edges respective projections 38. As above described, theside edges projection 38 are substantially normal to the other. In fully compressed position,slots 44 defined by and between adjacent edges, have substantially parallel side walls and extend radially from acentral locus 45 coincident with the central axis of theconnector 20. - Each
compressed slot 44 is bounded on longitudinal sides byopposed side walls adjacent projections 38. Theslots 44 are further bounded on their transverse sides by thecentral locus 45 and by theouter jacket 12. Thus it can be appreciated thatstrands 16, upon compression by the movement ofprojection 38, will be retained and compressed in the four elongaterectangular slots 44. Since eachadjacent wall such projections 38 is disposed parallel to each other, the compression will be uniform across the length of eachslot 44 i.e., radially fromlocus 45 tojacket 12. Thus theslots 44 will have a slot width, between twoadjacent side walls projections 38. Unlike spreading tines of U-shaped contacts or contacts having areas between the blades which are not defined by parallel sides, the present invention prevents tendency for thestrands 16 to move radially outwardly from thecentral locus 45 upon connection. Theconductor strands 16 are compressed without radial movement into a cross-shaped area defined byslots 44 which is substantially less than the original circular cross-sectional area by which the strands normally occupy, as shown in Fig. 4. The movement ofprojections 38, in addition to compressingstrands 16 intoslots 44 also slightly deforms thestrands 16 so as to provide for their accommodation in the smaller cross-sectional area. - Since the
strands 16 are bounded within theslots 44 as defined above, the connection formed, will be gas tight preventing oxidation of thestrands 16 at the point of connection. Further, as the strands are securely retained in theslots 44 presenting relative movement therebetween, the electrical connection will be permanent and not subject to intermittent contact. - As shown and described herein the present invention employs four
right angle projections 38 which upon compression form four extendingperpendicular slots 44 extending fromlocus 45 at 90° orientation from the adjacent slot. It is however contemplated that the present invention may also include other numbers of projections such as those which can have side edges formed at 120° thus providing three slots into which thestrands 16 can be compressed. It is noted however that in each case regardless of the number of slots, the side edges forming the slot will have parallel longitudinal sides thus preventing any radially outward migration of the strands upon connection. Other similar arrangements will also become evident to one skilled in the art. - Further it is contemplated that plural
conductive members 24 can be mounted in a single housing, in a multi-pin arrangement, for mass termination upon movement of the housing relative to such pluralconductive members 24. - While the above invention is described primarily for use with stranded wire it should be appreciated that the present invention may also be employed with wire having a solid conductor.
- Various other modifications to the foregoing disclosed embodiment will be evident to those skilled in the art. Thus, the particularly described preferred embodiment is intended to be illustrative and not limited thereto. The true scope of the invention is set forth in the following claims.
