Definitions
- This invention relates to devices for making electrical cross-connections between two sets of conductors and, in particular, to apparatus for electrically interconnecting first conductors with associated second conductors, the apparatus comprising a first connector of insulative material, provided with individual receiving and indexing means for the first conductors, and a second connector for mating with the first connector, comprising a body member of insulative material and a plurality of slotted beam contacts, each in a cavity in the body, one end of the slotted beam contacts for contacting the first conductors when the first and second connectors are mated, the other end of the slotted beam contacts for contacting the second conductors.
- wire connecting blocks of the type including an indexing strip and a connecting block wherein the connecting block carries a plurality of slotted beam contacts, such as disclosed in U.S. Patent No. 3,611,264.
- the indexing strip has a plurality of uniform height, spaced-apart teeth along its length. These teeth aid in indexing a first set of conductors.
- a corresponding plurality of uniform height, spaced-apart teeth carried by the connecting block serve to index a second set of conductors to be cross-connected through the slotted beam contacts to the first set of conductors.
- this improved connecting block is a two- piece structure, the parts of which are secured together following insertion of the slotted beam contacts. While this connecting block arrangement has proved to be satisfactory in some applications, it was found that when the connecting block is placed over the indexing strip in cold temperatures, certain stresses are applied to the bond between two connector parts. These stresses often rupture the bond causing failure of the entire unit.
- U.S. Patent No. 3,778,750 describes another connecting block which is a two piece structure the parts of which are secured together following insertion of the contacts.
- One part of the block is formed with integral pins which extend through holes in the contacts into holes in the other part of the block.
- the connecting block is used without an indexing strip.
- the second connector includes separate contact holding means which project into the cavity through a hole in the wall thereof, which physically engage in said hole, which coact with the contacts so as to hold the contacts in the body member, and which physically engage in a recess in the opposite wall of the cavity, whereby insertion forces produced during engagement of said slotted beam contacts with said indexed conductors tend toward shearing of said holding means rather than splitting of the body member.
- the body member in which the contacts are held can be manufactured as one piece, so avoiding rupture of a bond between parts thereof.
- assembly of the slotted beam contacts in the connector is facilitated by the use of the contact holding means which enables the contacts to be inserted easily in the body member and then secured by the contact holding means.
- a preferred embodiment of the invention has a L-shaped skirt integral with and projecting away from the second connector for encasing the end of the first conductors.
- a first mating connector hereinafter denoted as indexing strip 11 and shown in Figs. 1 through 3, includes a longitudinally extending body member 12. Integral with body member 12 and extending generally perpendicular to an axis thereof are a plurality of spaced-apart teeth 13. Teeth 13 alternate in height to facilitate indexing of a first set of conductors 14 shown in Fig. 9. To further facilitate wire indexing, teeth 13, as shown in Fig. 1, have tapered tip regions 15 on adjacent sidewalls 16. These tapered tip regions 15 form generally funnel-shaped wire entry ways for directing conductors 14 into wire retaining slots 17 formed by spaced-apart teeth 13.
- Adjacent sidewalls 16 of spaced-apart teeth 13 have integral therewith a pair of opposed depressions 18 for capturing and holding an indexed conductor 14 between the teeth in a wire retaining slot 17.
- Opposed depressions 18 are located at an intermediate point along the height of teeth 13 above wire retaining slot 17.
- edges 20 and 21 Extending along a length of body member 12 are outwardly projecting edges 20 and 21, as shown in Fig. 2. Edges 20 and 21 are at different elevations along body member 12 with edge 20 being at a lower elevation than edge 21 when viewed from tapered tip regions 15 of spaced-apart teeth 13. This difference in elevation of edges 20 and 21 enables only one way engagement of indexing strip 11 with a second mating connector 40, as shown in Fig. 9. Edge 21 has a width nearly twice the width of edge 20. This difference in width facilitates cutoff of first conductors 14 by a tool (not shown).
- a generally funnel-shaped channel 22 which is integral with sidewall 16 of spaced apart teeth 13.
- a similar channel 22 is integral with an opposed sidewall 16 of teeth 13.
- These funnel-shaped channels 22 have widths of greater extent at tip regions 15 of teeth 13 to facilitate directing slotted beam contacts 30, carried by second mating connector 40 and shown in Fig. 4, into engagement with indexed conductors 14, as shown in Fig. 9.
- Indexing strip 11 is affixed to a support carrier (not shown), similar to that illustrated as element 36 in Fig. 2 of U.S. Patent No. 3,798,587, by cylindrical posts 23. Posts 23 are inserted into apertures in the support carrier and heated to produce an expanded head similar to that of a rivet.
- a plurality of truncated cylindrical projections 24 are integrally provided on outer walls of spaced-apart teeth 13. Projections 24, as shown in Figs. 2 and 3, have a greater thickness near an edge opposite tip regions 15 of spaced-apart teeth 13. This coupling arrangement will be considered in further detail following the description of second mating connector 40.
- Each of contacts 30 includes a central portion 31 which has first and second pairs of oppositely directed cantilever beams 32 and 33 extending therefrom. Each of the beams in the pairs of beams 32 and 33 are spaced apart from one another by elongated generally rectangular apertures 34 and 35, respectively. Apertures 34 and 35 extend from central portion 31 to a point near a pair of oppositely directed insulation-penetrating edges 36 and 37, respectively, at the ends of beams 32 and 33. It should be noted that beams 33 are of shorter length than beams 32 to increase the force provided by edges 37 during engagement with conductor insulation. Also included in central portion 31 is a generally oval-shaped aperture 25 used in mounting contact 30 in mating connector 40.
- the second mating connector 40 shown in Fig. 4, comprises a body member 41 which has a plurality of elongate generally rectangular cavities 42 therein for slidably engaging slotted beam contacts 30. Extending partially along planar inner sidewalls 43 of cavities 42 are channel cavities 44. A corresponding plurality of spaced-apart apertures 45 are included in an outer sidewall 46 of body member 41. Spaced-apart apertures 45 are aligned in one-to-one correspondence with rectangular cavities 42 and channel cavities 44.
- Anchoring member 50 shown in Fig. 5 is comprised of a generally flat rectangular member 51. Integral with member 51 and extending outwardly therefrom are a plurality of spaced-apart generally triangular projections 52. Extending from tops of triangular projections 52 are projections 53 and 54. Interposed between projections 53 and 54 is a notch 55 the width of which is approximately equal to a width of central portion 31 between apertures 25 and 34 of contact 30. The projections 52, 53, 54 extend through and physically engage in the apertures 45 in the wall 46 of respective cavities 42, to hold the contacts in the cavities.
- Triangular projections 52 in conjunction with projections 53 and 54 and the depth of notch 55, limit the extent of engagement of slotted beam contact 30 with rectangular member 51. It should be noted that projection 53 extends through slot 34 in the contact to physically engage in channel cavities 44 and projection 54 extends through aperture 25 in the contact to physically engage in aperture 26.
- This mounting arrangement for slotted beam contacts 30 couples insertion forces produced during engagement of second mating connector 40 with indexing strip 11 into projections 53 and 54. Consequently, the insertion forces tend toward the shearing of projections 53 and 54 rather than the splitting of body member 41.
- the former includes a projecting lip 56 along a lengthwise edge 57.
- Outer sidewall 46 has a mating groove 48 extending along its length. This lip and groove arrangement provides a polarized mating of anchoring member 50 with body member 41.
- the two members 50 and 41 are secured to one another, for example, by ultrasonic welding.
- body member 41 has integral therewith and extending outwardly away therefrom a generally L-shaped skirt 61.
- a plurality of scallops 62 as shown in Fig. 4, along the base leg of the "L” and along opposite edge 63, engage conductors 14, as shown in Fig. 9, and hold them in place between indexing strip 11 and mating connector 40.
- Skirt 61 encases exposed ends 19 of first conductors 14 to electrically isolate them from one another. Not only does the insulative material of which both indexing strip 11 and mating connector 40 are made provide electrical isolation, but skirt 61 in conjunction with sealing compound (not shown) shields exposed ends 19 to prevent any accumulation of moisture which could cause electrical short circuits.
- mating connector 40 with the plurality of slotted beam contacts 30 therein is brought into engagement with indexing strip 11.
- Mating connector 40 is coupled securely to indexing strip 11 by projections 24 which engage a corresponding plurality of circular apertures 49 in sidewall 46 and skirt 61.
- Circular apertures 49 are aligned in correspondence with truncated cylindrical projections 24 so that apertures 49 surround projections 24 with the greater thickness inhibiting separation of mating connector 40 from indexing strip 11 once the two are mated.
- mating connector 40 holds the slotted beam contacts 30 in a spatial relationship so that an individual contact 30 is engageable with an individual conductor 14. Opposite ends of contacts 30 are now available for engagement with second conductors 39, as shown in Fig. 9.
- mating connector 40 has a plurality of spaced-apart, alternating height teeth 65 integral with body member 41.
- Teeth 65 have a configuration somewhat similar to that of teeth 13 on indexing strip 11 insofar as teeth 65 have tapered tip regions 66 forming funnel-shaped wire entry ways 67.
- Projections 71 have a thickness of greater extent at a central point therein which is removed from taper tip regions 66. Projections 71 facilitate capture and inhibit conductors 39 from separating from mating connector 40 after being seated in contacts 30.
- extended lateral projections 72 on teeth 65 as shown in Fig. 8. These extended projections 72 increase the electrical path length between adjacent exposed conductor ends. On outer edges of alternate ones of projections 72 are projecting lips 73 for facilitating engagement of a test cord (not shown) with mating connector 40.

Description
- This invention relates to devices for making electrical cross-connections between two sets of conductors and, in particular, to apparatus for electrically interconnecting first conductors with associated second conductors, the apparatus comprising a first connector of insulative material, provided with individual receiving and indexing means for the first conductors, and a second connector for mating with the first connector, comprising a body member of insulative material and a plurality of slotted beam contacts, each in a cavity in the body, one end of the slotted beam contacts for contacting the first conductors when the first and second connectors are mated, the other end of the slotted beam contacts for contacting the second conductors.
- In the prior art, wire connecting blocks of the type including an indexing strip and a connecting block are known wherein the connecting block carries a plurality of slotted beam contacts, such as disclosed in U.S. Patent No. 3,611,264. The indexing strip has a plurality of uniform height, spaced-apart teeth along its length. These teeth aid in indexing a first set of conductors. A corresponding plurality of uniform height, spaced-apart teeth carried by the connecting block serve to index a second set of conductors to be cross-connected through the slotted beam contacts to the first set of conductors.
- A number of improvements to this basic connecting block are disclosed in U.S. Patent No. 3,798,587. In order to facilitate mass assembly of the contacts in the connecting block, this improved connecting block is a two- piece structure, the parts of which are secured together following insertion of the slotted beam contacts. While this connecting block arrangement has proved to be satisfactory in some applications, it was found that when the connecting block is placed over the indexing strip in cold temperatures, certain stresses are applied to the bond between two connector parts. These stresses often rupture the bond causing failure of the entire unit.
- U.S. Patent No. 3,778,750 describes another connecting block which is a two piece structure the parts of which are secured together following insertion of the contacts. One part of the block is formed with integral pins which extend through holes in the contacts into holes in the other part of the block. The connecting block is used without an indexing strip.
- The problems of the prior art are solved by the invention in accordance with which the second connector includes separate contact holding means which project into the cavity through a hole in the wall thereof, which physically engage in said hole, which coact with the contacts so as to hold the contacts in the body member, and which physically engage in a recess in the opposite wall of the cavity, whereby insertion forces produced during engagement of said slotted beam contacts with said indexed conductors tend toward shearing of said holding means rather than splitting of the body member.
- In the claimed apparatus, the body member in which the contacts are held can be manufactured as one piece, so avoiding rupture of a bond between parts thereof. On the other hand, assembly of the slotted beam contacts in the connector is facilitated by the use of the contact holding means which enables the contacts to be inserted easily in the body member and then secured by the contact holding means.
- In other applications, such as outdoor environments, moisture collects across the exposed conductor ends. This moisture often times results in short circuits between some of the conductors. In an attempt to alleviate this problem, an insulative, greaselike compound is placed in the cavity of the connector disclosed in the said U.S. Patent No. 3,798,587. While this greaselike compound aids in the reduction of electrical short circuits, unfortunately, it further increases the mechanical stresses applied to the joint between the two connector parts as the connector is brought into engagement with the indexing strip.
- A preferred embodiment of the invention has a L-shaped skirt integral with and projecting away from the second connector for encasing the end of the first conductors.
- One way of carrying out the invention will now be described, by way of example, with reference to the attached drawings which illustrate one specific embodiment and in which:
- Fig. 1 is a side view of a first connector;
- Fig. 2 is an end view of the first connector;
- Fig. 3 is a top view of the first connector;
- Fig. 4 is an exploded partial perspective view of the second connector;
- Fig. 5 is a partial perspective view of a comb- like slotted beam contact retainer;
- Fig. 6 is a side view of the second connector;
- Fig. 7 is an end view of the second connector;
- Fig. 8 is a top view of the second connector;
- Fig. 9 is a composite end view of the first and second connectors aligned for mating connection with one another and further illustrating encasement of the exposed wire ends of the first set of conductors.
- A first mating connector, hereinafter denoted as
indexing strip 11 and shown in Figs. 1 through 3, includes a longitudinally extendingbody member 12. Integral withbody member 12 and extending generally perpendicular to an axis thereof are a plurality of spaced-apart teeth 13.Teeth 13 alternate in height to facilitate indexing of a first set ofconductors 14 shown in Fig. 9. To further facilitate wire indexing,teeth 13, as shown in Fig. 1, have tapered tip regions 15 onadjacent sidewalls 16. These tapered tip regions 15 form generally funnel-shaped wire entry ways for directingconductors 14 intowire retaining slots 17 formed by spaced-apart teeth 13. -
Adjacent sidewalls 16 of spaced-apart teeth 13 have integral therewith a pair ofopposed depressions 18 for capturing and holding an indexedconductor 14 between the teeth in awire retaining slot 17. Opposeddepressions 18 are located at an intermediate point along the height ofteeth 13 abovewire retaining slot 17. - Extending along a length of
body member 12 are outwardly projectingedges Edges body member 12 withedge 20 being at a lower elevation thanedge 21 when viewed from tapered tip regions 15 of spaced-apart teeth 13. This difference in elevation ofedges indexing strip 11 with asecond mating connector 40, as shown in Fig. 9. Edge 21 has a width nearly twice the width ofedge 20. This difference in width facilitates cutoff offirst conductors 14 by a tool (not shown). - Also shown in Fig. 2 is a generally funnel-
shaped channel 22 which is integral withsidewall 16 of spaced apartteeth 13. Asimilar channel 22 is integral with anopposed sidewall 16 ofteeth 13. These funnel-shaped channels 22 have widths of greater extent at tip regions 15 ofteeth 13 to facilitate directingslotted beam contacts 30, carried bysecond mating connector 40 and shown in Fig. 4, into engagement with indexedconductors 14, as shown in Fig. 9. -
Indexing strip 11 is affixed to a support carrier (not shown), similar to that illustrated aselement 36 in Fig. 2 of U.S. Patent No. 3,798,587, bycylindrical posts 23.Posts 23 are inserted into apertures in the support carrier and heated to produce an expanded head similar to that of a rivet. - In order to securely couple
indexing strip 11 tosecond mating connector 40, a plurality of truncatedcylindrical projections 24 are integrally provided on outer walls of spaced-apart teeth 13.Projections 24, as shown in Figs. 2 and 3, have a greater thickness near an edge opposite tip regions 15 of spaced-apart teeth 13. This coupling arrangement will be considered in further detail following the description ofsecond mating connector 40. - Once
conductors 14 are indexed, cross-connections among these conductors andconductors 39 of a second set, as shown in Fig. 9, are effected through a plurality of slottedbeam contacts 30, shown in Fig. 4. Each ofcontacts 30 includes acentral portion 31 which has first and second pairs of oppositely directedcantilever beams beams rectangular apertures Apertures central portion 31 to a point near a pair of oppositely directed insulation-penetratingedges beams beams 33 are of shorter length thanbeams 32 to increase the force provided byedges 37 during engagement with conductor insulation. Also included incentral portion 31 is a generally oval-shaped aperture 25 used in mountingcontact 30 inmating connector 40. - The
second mating connector 40, shown in Fig. 4, comprises abody member 41 which has a plurality of elongate generallyrectangular cavities 42 therein for slidably engaging slottedbeam contacts 30. Extending partially along planarinner sidewalls 43 ofcavities 42 arechannel cavities 44. A corresponding plurality of spaced-apart apertures 45 are included in anouter sidewall 46 ofbody member 41. Spaced-apart apertures 45 are aligned in one-to-one correspondence withrectangular cavities 42 andchannel cavities 44. - Once
slotted beam contacts 30 are inserted intorectangular cavities 42 and aligned such thataperture 25 is beneath acorresponding aperture 26, shown in Fig. 6, anchoringmember 50 is brought into engagement withbody member 41. Anchoringmember 50, shown in Fig. 5 is comprised of a generally flatrectangular member 51. Integral withmember 51 and extending outwardly therefrom are a plurality of spaced-apart generallytriangular projections 52. Extending from tops oftriangular projections 52 areprojections projections notch 55 the width of which is approximately equal to a width ofcentral portion 31 betweenapertures contact 30. Theprojections apertures 45 in thewall 46 ofrespective cavities 42, to hold the contacts in the cavities. -
Triangular projections 52, in conjunction withprojections notch 55, limit the extent of engagement of slottedbeam contact 30 withrectangular member 51. It should be noted thatprojection 53 extends throughslot 34 in the contact to physically engage inchannel cavities 44 andprojection 54 extends throughaperture 25 in the contact to physically engage inaperture 26. This mounting arrangement for slottedbeam contacts 30 couples insertion forces produced during engagement ofsecond mating connector 40 withindexing strip 11 intoprojections projections body member 41. - To ensure proper alignment of anchoring
member 50 withbody member 41, the former includes a projectinglip 56 along alengthwise edge 57.Outer sidewall 46 has amating groove 48 extending along its length. This lip and groove arrangement provides a polarized mating of anchoringmember 50 withbody member 41. The twomembers - As shown most clearly in Figs. 7 and 9,
body member 41 has integral therewith and extending outwardly away therefrom a generally L-shapedskirt 61. A plurality ofscallops 62, as shown in Fig. 4, along the base leg of the "L" and alongopposite edge 63, engageconductors 14, as shown in Fig. 9, and hold them in place betweenindexing strip 11 andmating connector 40.Skirt 61 encases exposed ends 19 offirst conductors 14 to electrically isolate them from one another. Not only does the insulative material of which bothindexing strip 11 andmating connector 40 are made provide electrical isolation, butskirt 61 in conjunction with sealing compound (not shown) shields exposed ends 19 to prevent any accumulation of moisture which could cause electrical short circuits. - After
first conductors 14 are individually received and indexed inindexing strip 11 and conductor ends 19 are trimmed to the proper length,mating connector 40 with the plurality of slottedbeam contacts 30 therein is brought into engagement withindexing strip 11.Mating connector 40 is coupled securely toindexing strip 11 byprojections 24 which engage a corresponding plurality ofcircular apertures 49 insidewall 46 andskirt 61.Circular apertures 49 are aligned in correspondence with truncatedcylindrical projections 24 so thatapertures 49surround projections 24 with the greater thickness inhibiting separation ofmating connector 40 from indexingstrip 11 once the two are mated. - It should be noted that
mating connector 40 holds the slottedbeam contacts 30 in a spatial relationship so that anindividual contact 30 is engageable with anindividual conductor 14. Opposite ends ofcontacts 30 are now available for engagement withsecond conductors 39, as shown in Fig. 9. - To facilitate alignment and indexing of
second conductors 39,mating connector 40, as shown in Figs. 6 through 8, has a plurality of spaced-apart, alternatingheight teeth 65 integral withbody member 41.Teeth 65 have a configuration somewhat similar to that ofteeth 13 onindexing strip 11 insofar asteeth 65 have taperedtip regions 66 forming funnel-shapedwire entry ways 67. Near the bottom ofwire retaining slots 68 formed byadjacent sidewalls 69 ofteeth 65 there are oppositely directedinterference projections 71.Projections 71 have a thickness of greater extent at a central point therein which is removed fromtaper tip regions 66.Projections 71 facilitate capture and inhibitconductors 39 from separating frommating connector 40 after being seated incontacts 30. - Electrical isolation is provided among exposed ends of
conductors 39 by extendedlateral projections 72 onteeth 65 as shown in Fig. 8. Theseextended projections 72 increase the electrical path length between adjacent exposed conductor ends. On outer edges of alternate ones ofprojections 72 are projectinglips 73 for facilitating engagement of a test cord (not shown) withmating connector 40.
