Theconnec- tor, which is bipartite and hemaphroditic, comprises similar parts 2 and 2', each comprising an insulating housing 4 having an open end 6, a base wall 8opposite thereto and side walls 10,11,13 and 15, upstanding from the basewall 8. The base and side walls cooperate with partitions 17 between the side walls to define four generally rectangular internal cavities i2inthe housing 4each opening into said open end 6.A row of four wire receiving through channels 14 is formed in the side wall 10 proximate to the base wall Randtnrough each of which channels 14 an end portion ofan insulated wire W can be inserted into a respective cavity 12 along a pred ec-:mined path. Two pairs of juxtaposed terminal cer4-;-g cartridges 16 and 18 are each lodged in a first,other position (Figures 4A, 4B and 5) in the open end 6 of the housing 4. Each cartridge 16 carries two
male electrical terminals 20 and each cartridge 18 carries two Female electrical terminals 22.Each terminal 20 and 22 comprises a wire receiving portion 24 formed with wire receiving slots 26 opening in a direct,ontowarcisíhe base wall 8. Each terminal 20 has a mating portion in the form of a plug 28, each terminal 22 having a mating portion 30 in the form of 3 receptacle. The mating portion ofeach terminal projects from its wire receiving portion in the opposite direction to that in which the slots 26 thereof oxen. The cartridges 16 and 18 are so disposed that tre slots 26 of the terminals of each cartridge open a- a respective one ofthe paths along which the Wi C W can be inserted into the cavity 12.
Fa.:a cartridge 16 and 18 is movable from said first r'eition, into a respective cavity 12 to a second, Rs:nc-, position (as best seen in Figures 4 and 6)to pierce the insulation of a wire Wand to engage the el.ectricaily conductive core C thereof (Figure 6), @@@@ @@ wire W has been inserted into the cavity 12 througt a respective one of the channels 14.The @@@ @ of the wires W are thereby forced into the @@@@ receiving slots 26 of the terminals 20 or 22, as the case may be, ofthe cartridge 16 or 18, electrically to connect the core C of a respective wire Wto both ofthe terminals ofthe cartridge.After each cartridge 16 and 18 of each ofthe parts 2 and 2' oftheconnector has been driven to its home position, the parts 2 and 2' are mated so that each plug 28 of each terminal 20 of one ofthe parts 2 or 2' is mated with a respective receptacle 30 of a corresponding terminal 22 ofthe other part 2 or 2' and each plug 28 of each terminal 20 ofthe other part 2 or 2' is mated with a respective receptacle 30 of a corresponding terminal 22 ofthe one part 2 or2'. Each wire W of the set of fourwires W inserted into the channels 14 ofthe part 2, is thereby electrically connected to a respective wire W of the set of fourwires W inserted intothe channels 14 of the part 2' .
The connector and its operation will now be described in greater detail.The cartridges 16 and 18 each comprise an insulating body 34formed with juxtaposed, parallel terminal receiving cavities 36 extending between, and opening into, a terminal receiving face 38 of the body 34. The body 34 has a mating face 32 opposite to its face 38. Upstanding from the face 38 ofthe body 34, centrally of its length, are terminal stabilizing members 44. At the right hand end (as seen in Figures 7 and 8) of the body 34 upstand a further pair of terminal stabilizing members 46 between which upstands a terminal guide plate 48 and adjacent to which also upstandsfrom the face 38, beyond the members 46, a cartridge guide plate 50 slidably engaged in grooves 51 in the respective cavity 12 and having a free end 53.A cartridge guide block 52 upstanding from the face 38 atthe left hand (as seen in Figures 7 and 8) end ofthe body 34 is provided with a stiffly resilient latching lip 54 which overhangs the left hand (as seen in Figures 7 and 8) end ofthe body 34 and ofthe block 52 and is also provided with a pairofterminal stabilizing members 53. The block 52 is surmounted by a strain reliefabut- ment 56. The body 34 ofthe cartridge 16 has, depending from its mating face 32, a hood 42.The body 34 of the cartridge 18 differs from that of the cartridge
16 in that it has depending therefrom, instead ofthe hood 42, a hood 58 ofsmallercross-section than the hood 42 and which is complementary therewith in that it can be received therein in mating relationship, as shown for example, in Figure 4, and is provided with in-turned protective lips 60.
The wire receiving portion 24 of each terminal 20 is in the form of a rolled up annulus into the upper(as seen in Figure 7) edge 62 of which the slots 26 open, the opposite edge 64 ofthe portion 24 being spanned by a substantially U-shaped divided strap providing the plug 28, the edge 64 providing terminal stabilizing shoulders 66 on either side of the plug 28. The portion 24 is maintained in its rolled up position by means of a tongue 65 in one lateral edge which engages in a groove inthe other. Theterminals20 and 22 are the same, excepting thattheterminal 22 has depending from its edge 64, opposed contact springs 68 instead ofthe plug 28. Each terminal 20 and 22 is received in one ofthe cavities 36 ofthe corresponding body 34 and is snuggly fitted between the stabilizing members 44 and 46 and 48, or44 and 53, as the case may be, with the shoulders 66 resting on the face 38. The plugs 28 ofthe terminals 20 project into the hood 42, as best seen in FigureS, and the contact springs 68 of the terminals 22 project into the hood 58 behind the lips 60 as best seen in Figure 4,so as to be protected thereby.
Each housing 4 has depending therefrom and extending beyond its open end 6, three peripherally spaced flanges 70,72 and 74 respectively, theflange 74 having a central latching opening 76 for receiving a latch member 78 on the other housing 4. Within these flanges, each housing 4 is formed with a peripherai groove 80 having an outwardly bowed base 81,and providing an emplacement for a low modulus of elasticity sealing ring 82. Opposite to the groove 80, the housing 4 is formed with a peripheral channel 83 to enhance the resilience of the groove base 81.
Wire sealing grommets 84 formed integrally with a connecting bar86areeach received in one ofthe channelsl4ofeach housing 4, each grommet84 having a cylindrical first portion 88 snuggly received inthemouthofthechannel 14and a portion 90 which is tapered inwardly ofthe cavity 12.
The base wall 8, is formed with internal grooves 90 defining wire stuffer ribs 92 for reception in the portions 24 of the terminals 20 and 22. The grooves 51 are defined byflanges 95 projecting fromthe partitions 17, as shown in Figure3.
When a cartridge 16 or 18 is in its first or outer position (see Figures 4A, 4B and 5) in the open end 6 of the housing 4, the lip 54 of the body 34 of thecartridge extends into atapered groove 98 in the wall 10 ofthe housing 4 as shown in Figures 4A and 5.
Each housing4hastherein a pairofcartridges 16 and a pair of cartridges 18, the cartridges of each pair being arranged immediately beside one another.
The steps needed electrically to connect the two sets of four wires W by means of the connector, will now be described. The wires of one set are inserted through respective grommets 84 of the connector part 2, the wires ofthe other set being inserted through respective grommets 84 ofthe connector part 2' to position the wires Win respective cavities 12, so that each wireWextends between the wall 8 of the corresponding housing 4and in alignment with the wire slots 26 of two of the terminals 18 or 20 as the case may be, (See Figure 5) and so that the wire W is received in the respective grommet 84 and extends therethrough (Figure 5).
With the wires so positioned, the cartridges 16 and 18Ofeach ofthe parts2 and 2' are pressed,forex- ample by means of a tool (not shown), towards the corresponding wall 8 that the lip 54 of each cart- ridge moves along the respective groove 98 until the lip 54, which is gradually compressed during its passage along the groove 98, resiles and snaps into engagementwith a shoulder 99 defined by the housing wall 10 proximate to the corresponding channel 14, and the free end 53 ofthe guide plate 50 ofthe cartridge simultaneously abuts the wall 8 as shown in Figure 4. During its movement into the cavity 12, the cartridge is guided by the engagement of its guide block 5; with the housing wall 10.As each cartridge reaches this home position the corresponding wire Al is forced by the corresponding stuffer ribs 92 into the wire slots 26 of the terminals of that cartridge (see Figure 6), electrically to connectthe core C of the wire W to these terminals. The wire W is gripped between the abutment 56 ofthe cartridge and the wall 8 so thatthe connection between the core C and the terminals is not disturbed if the wire W istensioned.
When each cartridge 16 and 18 of each connector part 2 and 2' has been so driven to its home position, the parts 2 and 2' are relatively oriented as shown in
Figure 2 and are then pressed together so that the flange 72 of the part 2 interdigitates between the flanges 70 and 74 ofthe part 2', the flange 70 ofthe part2, interdigitates between the flanges 72 and 74 ofthe part2', and the flange 74 of the part 2 interdigitates between the flanges 70 and 72 of the part 2'.
As the parts 2 and 2' are being so mated, the latching member78 of one part latches into the opening 76of the other part and the hood 58 of each cartridge 18 is received in the hood 34 of the corresponding cartridge 16, whereby each plug 28 is mated with the corresponding receptacle 30. In this mated condition of the parts 2 and 2', the sealing rings 82 thereof are resiliently deformed (Figure 6) by abutmenttherebetween so that a tight seal is provided between the parts 2 and 2' to restrain the ingress of moisture therebetween, assisted bythe resilient action of the bases 81 ofthe grooves 80. The ingress of moisture intotheconnectorthrough the channels 14 is restrained by the engagement ofthe end portions of the wires Win the grommets 84.
The second embodiment of the invention will now be discussed with reference to Figures 9 to 12, in which parts corresponding to those described above with reference to Figures 1 to 8 bear the same reference numerals but with the addition ofthesuffixlet- ter "a".
The second embodiment differs from the first in the following respects:
Each cartridge 18a and 20a has at one end awire strain relief abutment block 100 having a concave wire engaging face 102 and being divided buy a re ctangular cross-section slot 104 extending in the insertion direction ofthe cartridge, the block 100, also serving as a terminal stabilizing means, and between theterminals 20a or22a, as the case may be, is a terminal stabilizing plate 106 having a concave, wire en gaging,wirestrain relieffacel08,aterminalstabiliz- ing block 109 at the opposite end ofthe cartridge having opposed terminal stabilizing plates 110for snuggly engaging a terminal 201 or 22a between them.The block 102 has a shallow V-shaped groove 112 at its end remote from the block 100, extending in the cartridge insertion direction, and a jam cleat comprising a pairofupstandingwiregripping posts 114forgripping awireWbetweenthem.
Each cavity 12a ofthe parts 2a and 2'a has at one enda rectangularcross-sectionrib ll6extendingin the cartridge insertion direction, for reception in the slot 104 of the inserted cartridge, and at its other end a wide angle V-shaped projection 118 also extending in the cartridge insertion direction, for reception in the groove 112 ofthe inserted cartridgewhich is dim ensioned for snug reception in the cavity 1 2a so asto be lightlyforce fitted thereinto (Figure 12).
The latch means of each said part comprise a latch member 120 depending from the wall 1 Oa, and having a central opening 122 and on either side thereofa flange 124 defining a guide groove 126; acantilever latch arm 128 on the opposite wall, terminating in an overhanging stop flange 130 and having a latch projection 132 spaced from theflange 130; and a pair of guideflanges 134, one on each side of the arm 128 and each terminating in a guide rib 135 over hanging the arm 128.
On the wall 8a is a mounting strap 138.
Each sealing ring 82a is molded in situ to the housing 4a and is provided with a V-shaped groove 138 (Figure 11) to enhance its resilience.
When wires W have been inserted into the chan nels 14a, the cartridges are moved to their home pos itie is so thatthe wires Ware trapped between the Cjcas 102, 108, of the cartridges and the respective well 8a, and are also gripped between the posts 114 Df cartridges (Figure 12), each wire being forced into the wire slots 26a of the terminals of one of the cartridges by the stuffer ribs 92a, in the manner described above with reference to the first embodiment.
The posts 1 serve to jam the cartridge in its cavity.
As the parts 2a and 2'a are being mated, the guide ribs li36 of one part are received in the guide grooves 126 of the other part so thatthe latching projection igure 1 IA) ofthe latch arm 128 of one part is guided into the opening 122 of the latch member 120 ofthe other part, the an 128 being resiliently depressed towards the wall 1 3a until the member 120 buttsagainsttheflange 130 ofthe arm 128. The two parts are thereby locked in mating relationship.
The parts 2a and 2'a are then mated to electrically connectthetwo sets of wires in the mannerdescri
bed above'ith reference to the first embodiment.
The parts 2a and 2'a can be unmated by pressing each arm 128 towards the adjacentwall 13a and pul
ling the two parts away from one another.
The connector is not necessarily hermaphroditic and the e cartridges may be of any convenient number and r,-eed not he arranged in pairs of like cartridges.
