Abstract
A B S T R A C T - CANADA
A terminal for two conductors has two slotted plates joined together in adjacent parallel planes with the slot mouths at least partly in registration. The slots are formed with two wire-receiving sections. In the first section, the slot walls of the first plate are offset in a first lateral direction from the slot walls of the second plate and in the second section the lateral offset is in the opposite lateral direction so that a conductor is gripped in the first section between a first slot wall of the first plate and a second slot wall of the second plate and in the second section between a second slot wall of the first plate and a first slot wall of the second plate. The presence of the second conductor in the slots enchances the gripping force on the first conductor and vice versa.

Figure 18 is a fragmentary perspective view of a wire-C~h ~1 ~h tJ, B connecting portion of-~-nrnt~ example of terminal; and Figure 19 is a schematic view of a ~e~*~ example of terminal according to the invention.
The first example o terminal 11 is stamped and formed from a single piece of sheet metal and comprises first and second metal plates 12 and 13 respectively joined together at one end by a bight 14 to extend adjacent in opposed, parallel relation. The plates have first and second slots lS and 16, respectively, extending from the other end and the second plate is joined at the other end by a pair of straps 18 to a third plate 19 having a third slot 20 aligned with the first and second slots. The plate 19 extends from one end of a body portion 21 joined at its other end to a contact portion (not shown) and provided with a latching tongue 22 to latch the terminal in a housing.
The first and second slots extend in the same direction in partial registratLon from adjacent mouths and comprise first and second wire-receiving sections 23,24 and 25,26 successively longitudinally spaced from the mouths, first and second walls 27 and 28 of the first slot 15 being respectively offset in a first lateral direction from first and second walls 29 and 30 of the second slot 16 in the first sections 23,24 and first and second walls of the first slot being respectively offset ... , - . .
,~
1083~38 8917 Erom first and second walls of the second slot in a second lateral direction, opposite to the f irst lateral direction in the second sections 25,26. The first and second sectlons are joined by transition regions disclosed in more detail in Figures 15 to 17 below.
In use, a first insulated wire is inserted perpendicularly of its axis through the mouths and the first slot sections into the second slot sections. During its passage through the first slot sections, (Figure 3), the wire is gripped between the first wall 27 of the first slot and the second, opposite wall 30 of the second slot with penetration of the insulation and relative lateral pivotal movement of the first and second plates in their planes in one direction. ~lovement of the first wire through the transition region into the , 1~ second slot sections (Figure 4), causes relative pivotal movement of the plates in the opposite direction and the wire is gripped between the second wall 28 of the first r slot and the first, opposite wall 29 of the second slot.
Subsequent insertion of a second similar, wire into the first slot sections, (Figure 5), causes relative pivotal movement of the plates into alignment by engagement of the second wlre and the irst wall 27 of the second slot and the second wall 30 of the second slot, increasing the gripping force on the first wire.
Thus, an increasing gripping force is applied to the w~re core during progression from Figure 3 to Figure 5, caused particularly by the insertion of the second wire into , .
. - ' ' .
' ' .
~917 1083'~38 the first slot sections. l~he presence of the first ~ire in the second slot sections also increases the gripping force on the second wire core in the first slot sections.
Thus, the ~ripping force on a wire core is greater ~here S two wires are present in the respective slot sections than ~here only one wire is present. The bight 14 maintains the gripping force.
The third slot may grip the wires to provide strain relief. If desired, the separation of the first wall 22 of the first slot and the second wall 30 of the second slot may be greater than the separation of the second wall 28 of the first slot and the first opposite wall of the second slot in the second slot section.
The connector of Figure 6 comprises an insulating housing 40 mounted in an aperture in a panel 41 and in which are mounted two rows of opposed terminals 11. Each terminal has a bowed spring contact portion 42 extending from the body 21 and provided within ears 43 at its free end which latch behind shoulders 44 of the housing to reta~n the terminals in the housing with the contact portions 42 bowed towards each other in preloaded condition to grip between them a printed circuit board or terminal ~ posts.
: In the connector of Figure 7, the terminals'11 are modified principally in that the body portions 46 extend perpendicularly to the slotted plates so that the wires can be inserted into the slots in a direction parallel to : ~ , ,., ,: .

~083Z38 to the panel 41 rather than from a direction perpendicularly to the panel.
In the second example of terminal 50 shown in Figure 8 the slot mouths 51 open into a bight 52 integrally joining first and second plates 53 and 54. As a result of the split, bight, the wire connection portion of terminal can be made by a single stamping step whereas the first example of terminal requires two stamping steps as the first and second slots are separated by the material forming the bight 14.
The wire connecting portion of the third example `!
of terminal 60 shown in Figure 9 differs from the first ex-ample in that three slot sections 61, 62 and 63 respectively are provided. The first and third slot sections are aligned with each other but laterally offset from the second slot section 62 in a similar fashion to the first example. The separation of the co-operating walls of the sections may be diferent from section to section if desired.
The wire connecting portions of the fourth ex-ample 67 shown in Figure 10 are provided with a post 69 which is anchored in a plastics substrate 70.
In the fifth example 71 shown in Figure 11, first and second slotted plates 72 and 73 are integrally joined along one edge by bight 74 parallel to the slots which are similarly shaped and arranged to the slots of the first ~., :

5 ~ In the ~v~m~ e~ample 77 sho~m ln Figure 12, two wire connecting portions 78 and 79 each similar to the first example are located in side-by-side relation in a sinyle metal piece enabling a single terminal to accommodate four wires.
As shown in Figure 13, edges of co-operating slot walls 81 and 82 may be bevelled on opposite sides to contact a wire with the wire aligned more nearly in a plane normal to the wire length than in the absence of such bevels.
This reduces the torque exerted locally on the wires by such edges. As shown in Figure 14, the edges 83 and 84 may also be bent towards each other to bring the planes of contact with the wire inserted between them more normal to the wire axis. Edges 85 and 86 of non-gripping slot walls may be bent away from the edges 83 and 84 to permit lateral movement of such edges away from each other during wire i~sertion.
s ~ ~
In the eight~ example 87 shown in Figures 15 to 17, first and second slot sections are longitudinally spaced by a transition region 88 of length x providing a passage-way permitting a conductor to pass between the slot sections without being pinched between transition edges 89 and 90 of slot walls 91 and 92. The amount of lateral ofset o tllc wa]ls of the first and sccond slots to-~ether with the inclination of the transition edges and the length x may be choscn so that a passa~e~ay oE rnaximum and constant width is provided for A conductor throughout its travel along and between the two slo~ sections.
As shown in more detail in Figure 17, the angle between transition edges 93 and 94 and the longitudinal slot edges 95 and 96 is preferably 30 degrees to provide a passageway of rear minimum resistance for a conductor passing through the transition region while angle B, between a line joining upper ends of opposite transition edges 93 and 89 of the same plate should lie between 12 and 20 degrees, to provide a passageway of equal width to either of the fixst or second slot sections.
1S B In the ninth example of terminal 98 shown in Figure 18, the above mentioned transition region is incorporated and a wire-stop 99 is pushed out of third plate 101 to limit the depth of insertion of a wire into the second slot section.
As shown in Figure 19, in a t~ffl~example 102, the shaded non-co-operating opposite wall portions 103, 104 of cc-~ b,~ orn~tf~d the first slot sectlon~as only one slot wall of each plate is required to provide the first wire gripping slot section.
The widths of slots in first sections may be greater than - in second sections and the lateral offset distances between 510t walls of the first and second plates can be chosen to provide a second resultant wire gripping section 110 of less width than the upper section 111 to grip a smaller 1083;~:38 di.ameter conductor.
The lead in edges 112 and 113 of the first and second plates 105,106 respectively may be of differing length and angles so that a wire engages corners 114 and 115 at different times lowering resistance to the wire being lnserted.
