Definitions
- This invention concerns a multigauge insulation displacement connector and contacts therefor, and particularly concerns such a connector and contacts adapted for use with multistranded conductors.

- the contact member may be formed with a protrusion projecting outwardly from a major surface of the contact member adjacent the narrow section of the slot thereby increasing the width of the narrow section of the slot in the region of the protrusion.
- the protrusion then serves to separate the insulation displaced by the slot.
- the slot may define a pair of limb portions and the limb portions may be deformable away from each other upon introduction of a conductor therebetween. Accordingly, stresses are not transferred to a housing for the contact member in concentration.
- the contact member may be reversely bent to define a bight portion and the bight portion may be formed with a slot therein for receiving and making an electrical connection with a terminal member introduced therewithin.
- An insulation displacement connector comprises an electrically insulating connector housing having one or more recesses therein for receiving a contact or terminal member constructed according to the teachings of the present invention.
- the said recesses will be open at least at one end corresponding to the mouth end of the contact member, and preferably will be formed for directing and guiding a conductor wire inserted therein. into the mouth of the associated contact member and will include strain relief formations such as resilient displaceable strain relief fingers which are displaced by a conductor wire inserted into the connector and then resile to hinder or prevent withdrawal of the conductor.
- the recess of the connector housing can advantageously be open at both ends, for example in the case of a connector employing reversely bent contact members as above described wherein the bight portion is slotted to provide access for a spade terminal to engage in the slot of the contact member.
- a blank designated generally by the reference numeral 10, formed by stamping suitable metal of selected thickness in sheet or strip form.
- the blank 10 includes a plurality of plate-like elongated contact blanks 11, each connected at one end to a carrier strip 12.
- Each blank 11 comprises an insulation displacement slot formation 13 at both ends thereof, defining edge surfaces 13' which-are of suitable sharpness to sever the insulation of a conductor.
- an elongate slot 14 of predetermined shape, which will be described in greater detail hereafter.
- Each blank 11 is generally symmetrical, both longitudinally and transversely and is designed to be folded end-to-end into a generally U-shape as shown in Fig. 2.
- Folding of a blank 11 defines a double-ended insulation displacement contact 15 with the insulation displacement slot-formations 13 in alignment with one another.
- the elongate slot 14 defines a bifurcated contact formation suitable to engage a spade terminal or the like.
- the contact 15 is seen to include a relatively wide mouth 17 which narrows inwardly in a stepped and tapering fashion through three stages, designated generally by the reference numerals 18, 19 and 20, respectively.
- a pair of teeth 21 of sharp triangular shape and juxtaposed on opposite sides of the slot 13 project from the regions defined between stepped portions 19 and 20 with their apices pointed generally inwardly of the slot 13 towards the open mouth 17.
- Opposed edges 22 of the teeth 21 taper inwardly towards each other in a direction away from the mouth 17.
- Stepped portions 20 define a generally parallel section 23 of relatively long length which terminates in an enlarged hole 24.
- each side of the insulation displacement slot 13 has a slight protrusion 25 projecting from one surface of the blank 11, coind therein as, for example, by coining of the blank 11.
- the insulation displacement slot 13 thus defined lies between two limbs 26 which taper so as to be to a degree resiliently flexible. Free ends 27 of the limbs 26 adjacent the open mouth 17 of the slot 13 are sufficiently narrow such that the limbs 26 are bendable along their entire length.
- the elongate slot 14 formed in the blank 11 results in bifurcation of the bight of the contact member 15 to define two opposed limbs 30 which form therebetween a female contact receptacle 31 adapted for receiving a male contact member (shown in Fig. 6).
- the slot 14 is further adapted with lugs 32 projecting into the female contact receptacle 31.
- Figure 3 shows various steps in the insertion of a relatively small gauge, multistranded, insulated conductor 33a into the insulation displacement slot 13 of three contact members as just described, designated 15a, 15b and 15c.
- the contact members 15a, 15b, and 15c are each identical in their construction and accordingly, like reference numberals will be used, hereinafter to describe the operation of their various features.

- Each contact member 15a, 15b and 15c is schematically shown engaged in an acccomodating recess 36 in an illustrative connector housing 37.
- Contact 15a is sham with the conductor 33a being guided by wall formations 38 in the housing 37 towards the mouth 17 of the insulation displacement slot 13.
- Contact 15b is shown with the conductor 33a just engaged with the insulation piercing teeth 21 of slot 13 and with the teeth 21 just beginning to penetrate and to pare off a section of the conductor insulation 35a.
- Contact 15c is shown with the conductor strands 34a lodged well down into the generally parallel section 23 of the insulation displacement slot 13 in the region of the coined protrusions 25, where the protrusions 25 slightly widen and strengthen the slot 13.
- a further advantage of the protrusions 25 is that they cooperate to separate the insulation 35a longitudinally of the wire 33a inasmuch as they protrude from the blank 10 in oppositely directed pairs (Fig. 2).
- This separation of the insulation 35a allows for greater exposure of the conductor strands 34a to the contact slot 13.
- a plug of insulation 40c remains above and below the conductor strands 34a in the slot 13 of the contact member 15c and remnants 41c of pared off insulation remain on the teeth 21.

- the limbs 26 of contact 15c is slightly opened as the conductor core 34a is forced into the slot 13. This brings the free ends 27 of the said limbs 26 into abutting engagement with the housing 37.
- Fig. 4 is similar to Fi g . 3 but shows the insertion of a considerably larger gauge conductor 33b into contacts 15d, 15e and 15f.
- contacts 15d, 15e and 15f have been sham with reference numerals corresponding to like elements of the contact 15 illustrated in Fig. 2.

- the additional strains involved are at to a great extent accommodated within the contact member 15f itself, rather than being transferred to the connector housing 37. This has the desirable effect of minimizing the risk of housing distortion.

Access is provided at the top and bottom ends of the housing 51 to the insulation displacement slot 13 and the female receptor 31, respectively, of each contact 15.
- the housing 51 and the recess 52 therein have upper and lower portions 53 and 54, respectively, which provide accommodation for the (upper) insulation displacement portion 13 of the contact member 15 and the (lower) female receptor 31, respectively.

Abstract
Description
- This invention concerns a multigauge insulation displacement connector and contacts therefor, and particularly concerns such a connector and contacts adapted for use with multistranded conductors.
- Insulation displacement connectors do not require the stripping of insulation from a section of an insulated conductor preparatory to insertion of the conductor into the connector. Rather, they rely upon displacement of the insulation of the conductor by the sides of a slot in a contact or terminal member into which the conductor is introduced.
- Many different forms of insulation displacement connectors have been successfully marketed in recent years. A need still exists for such a connector which not only is usable with multistranded conductors, but also is usable with a range of conductor sizes or gauges. The difficulties which arise in the application of insulation displacement technology to connectors for use with multistranded conductors are known and are discussed in U.S. Patent No. 4,317,608. Generally, these difficulties result from undesirable rearrangement of the conductor strands upon their insertion into the connector contact member. As a consequence of such rearrangement, a reliable electrical connection between the conductor and contact member cannot be assured, particularly if the connector is to be used with varying conductor sizes.
- It is, therefore, a principal object of the present invention to provide an improved contact member for an electrical connector having the capability of establishing a reliable electrical connection with a stranded wire.
- A further object is to provide a contact member which is equally suitable for use with both small and large gauge wires.
- The present invention provides a contact member for an electrical connector having an insulation displacement slot therein defining opposed edge surfaces for providing electrical connection to an insulated conductor, the slot having a mouth leading to a relatively narrow section there being at least one tooth projecting into the slot for piercing the insulation of a conductor introduced therein.
- The contact member may be formed with a protrusion projecting outwardly from a major surface of the contact member adjacent the narrow section of the slot thereby increasing the width of the narrow section of the slot in the region of the protrusion. The protrusion then serves to separate the insulation displaced by the slot.
- The slot may define a pair of limb portions and the limb portions may be deformable away from each other upon introduction of a conductor therebetween. Accordingly, stresses are not transferred to a housing for the contact member in concentration.
- The contact member may be reversely bent to define a bight portion and the bight portion may be formed with a slot therein for receiving and making an electrical connection with a terminal member introduced therewithin.
- An insulation displacement connector according to the present invention comprises an electrically insulating connector housing having one or more recesses therein for receiving a contact or terminal member constructed according to the teachings of the present invention. The said recesses will be open at least at one end corresponding to the mouth end of the contact member, and preferably will be formed for directing and guiding a conductor wire inserted therein. into the mouth of the associated contact member and will include strain relief formations such as resilient displaceable strain relief fingers which are displaced by a conductor wire inserted into the connector and then resile to hinder or prevent withdrawal of the conductor. The recess of the connector housing can advantageously be open at both ends, for example in the case of a connector employing reversely bent contact members as above described wherein the bight portion is slotted to provide access for a spade terminal to engage in the slot of the contact member.
- In order that the invention might be clearly understood, a number of embodiments thereof will hereinafter be described by way of example only with reference to the accompanying drawings wherein :-
- FIG. 1 shows a portion of a sheet metal stamping used for manufacturing contact members according to one embodiment of the invention;
- FIG. 2 shows in enlarged perspective view a contact member formed from the sheet metal stamping of Fig. 1;
- FIG. 3 shows stages in the insertion of a small gauge multistranded conductor into the contact member of Fig. 2;
- FIG. 4 shows corresponding stages in the insertion of a relatively large gauge multistranded conductor into the same contact member of Fig. 2;
- FIG. 5 shows, in perspective view, a four circuit connector in accordance with the invention which employs a contact member according to the preceding figures, and
- FIG. 6 shows a sectional view on taken generally along the line 5-5 of Fig. 5.
- With reference to the accompanying drawings and first to Fig. 1, there is shown a blank, designated generally by the
reference numeral 10, formed by stamping suitable metal of selected thickness in sheet or strip form. The blank 10 includes a plurality of plate-likeelongated contact blanks 11, each connected at one end to acarrier strip 12. Each blank 11 comprises an insulationdisplacement slot formation 13 at both ends thereof, defining edge surfaces 13' which-are of suitable sharpness to sever the insulation of a conductor. Intermediate the said ends is anelongate slot 14 of predetermined shape, which will be described in greater detail hereafter. Each blank 11 is generally symmetrical, both longitudinally and transversely and is designed to be folded end-to-end into a generally U-shape as shown in Fig. 2. - Folding of a blank 11 defines a double-ended
insulation displacement contact 15 with the insulation displacement slot-formations 13 in alignment with one another. At the bend or bight of the U-shape, theelongate slot 14 defines a bifurcated contact formation suitable to engage a spade terminal or the like. - Looking at Fig. 2, the
contact 15 is seen to include a relativelywide mouth 17 which narrows inwardly in a stepped and tapering fashion through three stages, designated generally by thereference numerals teeth 21 of sharp triangular shape and juxtaposed on opposite sides of theslot 13 project from the regions defined betweenstepped portions slot 13 towards theopen mouth 17. Opposededges 22 of theteeth 21 taper inwardly towards each other in a direction away from themouth 17. Steppedportions 20 define a generallyparallel section 23 of relatively long length which terminates in an enlargedhole 24. About midway along the length of theparallel section 23, each side of theinsulation displacement slot 13 has aslight protrusion 25 projecting from one surface of the blank 11, fermed therein as, for example, by coining of the blank 11. - The
insulation displacement slot 13 thus defined lies between twolimbs 26 which taper so as to be to a degree resiliently flexible.Free ends 27 of thelimbs 26 adjacent theopen mouth 17 of theslot 13 are sufficiently narrow such that thelimbs 26 are bendable along their entire length. - The
elongate slot 14 formed in the blank 11 results in bifurcation of the bight of thecontact member 15 to define twoopposed limbs 30 which form therebetween afemale contact receptacle 31 adapted for receiving a male contact member (shown in Fig. 6). Theslot 14 is further adapted withlugs 32 projecting into thefemale contact receptacle 31. - Figure 3 shows various steps in the insertion of a relatively small gauge, multistranded, insulated
conductor 33a into theinsulation displacement slot 13 of three contact members as just described, designated 15a, 15b and 15c. Thecontact members - The
conductor 33a comprises multiple strands ofconductive wire 34a coated with a layer ofinsulation 35a. Eachcontact member acccomodating recess 36 in anillustrative connector housing 37. Contact 15a is sham with theconductor 33a being guided bywall formations 38 in thehousing 37 towards themouth 17 of theinsulation displacement slot 13. Contact 15b is shown with theconductor 33a just engaged with theinsulation piercing teeth 21 ofslot 13 and with theteeth 21 just beginning to penetrate and to pare off a section of theconductor insulation 35a. Contact 15c is shown with theconductor strands 34a lodged well down into the generallyparallel section 23 of theinsulation displacement slot 13 in the region of the coinedprotrusions 25, where theprotrusions 25 slightly widen and strengthen theslot 13. - A further advantage of the
protrusions 25 is that they cooperate to separate theinsulation 35a longitudinally of thewire 33a inasmuch as they protrude from the blank 10 in oppositely directed pairs (Fig. 2). This separation of theinsulation 35a allows for greater exposure of theconductor strands 34a to thecontact slot 13. A plug ofinsulation 40c remains above and below theconductor strands 34a in theslot 13 of thecontact member 15c andremnants 41c of pared off insulation remain on theteeth 21. Theteeth 21 thus server when the conductor core gauge is small relative to the insulation thickness, to positively pare away part of the insulation and thereby reduce the insulation displacement task of theparallel section 23 of theslot 13. - The
limbs 26 ofcontact 15c is slightly opened as theconductor core 34a is forced into theslot 13. This brings thefree ends 27 of the saidlimbs 26 into abutting engagement with thehousing 37. - Fig. 4 is similar to Fig. 3 but shows the insertion of a considerably
larger gauge conductor 33b intocontacts contacts contact 15 illustrated in Fig. 2. - Notable in Fig. 4 as compared to Fig. 3 is the earlier deformation of the conductor cross-section as the
conductor 33b is forced into themouth 17 of thecontact 15e, and the increased deformation of thelimbs 26 which bow as thelarger conductor 33b is inserted. The additional strains involved are at to a great extent accommodated within thecontact member 15f itself, rather than being transferred to theconnector housing 37. This has the desirable effect of minimizing the risk of housing distortion. - Referring now to Figs. 5 and 6, there is showm therein a four
circuit connector 50 for use with acontact member 15 as above described. Theconnector 50 comprises a onepiece housing 51 of glass filled Nylon, for example, having a plurality of open ended recesses orchannels 52 therein for receiving thecontacts 15. Access is provided at the top and bottom ends of thehousing 51 to theinsulation displacement slot 13 and thefemale receptor 31, respectively, of eachcontact 15. - As shown most clearly in Fig. 6, the
housing 51 and therecess 52 therein have upper andlower portions insulation displacement portion 13 of thecontact member 15 and the (lower)female receptor 31, respectively. Theupper portion 53 has formed therein opposed pairs ofgrooves 55 into which the edges of the twoinsulation displacement portions 13 of thecontact member 15 engage when thecontact member 15 is received in thehousing recess 52. Theupper portion 53 also has a pair ofribs 56 of triangular cross-section disposed one on either side of the pairs ofgrooves 55, theribs 56 being tapered at their upper ends, as best seen in Fig. 5, to provide guidance to aconductor 33 introduced into therecess 52. Not only do theribs 56 provide the guidance aforementioned, but also they serve to strengthen the housing and to retain aconductor 33 once it has been engaged with the connector. - As best seen in Fig. 6, the
lower part 54 of thehousing recess 52 is of simpler form and comprises amajor portion 57 which accommodates thefemale receptor 31 of thecontact member 15 and slottedportions 58 extending at right angles off of themajor portion 57. The slottedportions 58 serve to guide and retain atab terminal 59 inserted into contact with thefemale receptor 31 of thecontact member 15. Although not shown, slottedportions 58 may be configured such thattab terminal 59 is offset laterally with respect to thefemale receptor 31, allowing anaperture 60 of thetab terminal 59 to be engaged by thelugs 32 of thefemale receptor 31, thereby effecting a locking function. - The
housing 51 further comprisesentry ports 60 which are provded with a variety ofstrain relief formations 61 enabling aconductor 33 received in theconnector 50 to be bent substantially through 90 degrees so as to extend from theconnector 50 generally parallel to the longitudinal axes of theterminals 15, as illustrated in Fig. 6. A pair of opposed, resilientstrain relief fingers 62 depend from the housing walls within theentry port 60 and are such as to be resiliently deformable out of the path of aconductor 33 introduced into theconnector 50 by contact with theconductor 33. Once theconductor 33 has been fully positioned, thestrain relief fingers 62 resume their original disposition and prevent withdrawal of theconductor 33. Also provided is amember 63 of generally triangular cross-section which performs a function similar to that of theribs 56, and opposedmembers 64 which serve as conductor guiding and retaining means particularly when, as aforementioned, the conductor is bent through 90 degrees to exit from theconnector 50. - The
connector 50 described is particularly, though not exclusively, useful in consumer and automotive applications where it lends itself to automatic assembly of wiring harnesses and can reliably mate with standard terminal tabs. As an example of the gauge range which might be accommodated, a connector according to the invention might be designed for use with isultistranded conductors ranging from 0.5 mm (16 strands each of 0.2 mm diameter) to 1.5 mm (30 strands each of 0.25 mm diameter) core area with insulation thicknesses of the order of 0.6 mm to 0.7 mm providing an overall conductor diameter range of 2.2 mm to 3.2 mm. Although the illustrative embodiment is of a four circuit connector, any member of circuits may be terminated in accordance with the principles of the invention, within the ordinary skill in the art.
