Abstract
ABSTRACT
A slotted plate terminal has a first slot portion with parallel sides which axe spaced by a distance less than the sum of the diameters of two wires to be connected by means of the terminal and exceeding the diameter of either wire, and two second slot portions which diverge away from the first slot portion and each of which is of smaller width than the diameter of either of the two wires. When positioned in the first portion of the slot, the wires are necessarily at different levels.
When the wires are forced towards the second slot portions the leading wire moves into one of the second slot portions and also serves to cam the trailing wire into the other of the two second slot portions. An electrical connector which utilises such terminals for the connection of multi-wire flat cable is also disclosed.

106~031 having at its lower (as seen in Figure-l) end, a base in the form of a metal commoning strip 94 by which the terminal is connected to other and similar terminals tnot shown in Figure 1). The plate 2 has an upper (as seen in Figure 1) edge 6 in-to which opens a flared mouth 16 of a bifurcated wire receiving slot 8 formed in the plate 2. The mouth 16 communicates, in the inward direction of the slot 8 i.e. towards the base, with a parallel sided portion 14 of the slot, which in turn commun-icates in the inward direction of the slot 8, with two slot portions 18 and 20 which diverge in the direction of the base and between which lies a triangular portion 22 of the plate having a rounded apex 24 directed away from the base, the slot portions 18 and 20, in turn communicating in the inward direc-tion of the slot 8 with respective parallel slot portions 25 and 26.
` As shown in Figure 1, the width of the slot portion 14, which is constant, is greater than the diameter of either of metal wires 28 and 30 to be terminated by means of the terminal 1 but is of smaller width than the sum of the diameters of the wires 28 and 30, the width of each slot portion 18 and 20 being less than the diameter of either of the wires 28 and 30. The width of the slot portion 25 is l-ess than that of the slot por-tion 18, the width of the slot portion 26 being less than that of the slot portion 20. Although the slot portions 18 and 20 may decrease in width towards the base, it is essential that ~-their width at the apex 24 be less than the diameter of either of the wires 28 and 30.
In order to terminate the wires 28 and 30 by means of the terminal 1, these wires are inserted through the mouth 16 of the slot 8 into the slot portion 14 and are forced by means _ 4 _ . ~

of a tool 32 having an opening 34 receiving the plate 2, into the slot portions 18 and 20, by advancing the tool 32 towards th~ base, i.e. in t~e direction of the arrow A in Figure 1, the base being supported on a rigid surface (not shown in Figure 1). Since the width of the slot portion 14 is less than the sum of the diameters of the wires 28 and 30, the wires are necessarily lie at different levels with respect to one another during their passage through the slot portion 14 as shown in Figure 1. As the tool 32 is advanced, the leading wire (28 in :
Figure 1) is diverted by the apex 24 into one of the divergent slot portions (the portion 1~ in Figure 1). The trailing wire (30 in Figure 1) is diverted by the leading wire into the other divergent slot portion (the slot portion 20 in Figure 1), since considerable force is needed to drive the leading wire into its lS divergent slot portion, in view of the restricted width of this portion and of its angle of divergence (approximately 20) with ~:
respect to the vertical. As the tool 32 is further advanced in the direction of the arrow A, each of the wires is forced from its divergent slot portion into the communicating parallel slot portion 25 or 26 as the case may be, where the wire is deformed to subtantially oval cross-sectional shape as indicated in broken lines in Figure 1, by virtue of the small width of the parallel slot portion, whereby permanent electrical contact is made between the wire and the plate 2. If the wires are surr~ ....~ ..
ounded by insulating sheaths (not shown) these will be cut through by the walls of the slot portions through which the wires pass.
A first electrical connector comprising terminals accoxd-ing to Figure 1 will now be described with reference to Figures 2 to 5. The connector comprises an insulating base 99 provided ':
_ 5 _ 106503~
with parallel slots 112 each communicating at one end with a tubular channel 98 and being defined by fingers 113 upstanding from a flat bed 97. A shoulder 96 projects from the bed 97 at a position spaced from, and opposite to, the end faces of the ~
fingers 113 remote from the channels 98. An array of electrical :
contact elements 9S rests upon the bed 97, each contact ele-ment 95 comprising a metal strip 111 having at one end a pin receptacle 93 and at the other end a terminal 1, these contact elements being commonly connected by strips 94 bridging the terminals 1. Each contact element 95 is positioned on the bed 97 with its receptacle 93 in one of the slots 112 and in align- ;
ment with a channel 98 through which a male contact member in the form of a pin (not shown) can be inserted to mate with the receptacle 93. These terminals 1 are positioned near the , 15 shoulder 96 as shown in Figure 4.
An insulating member 92 comprising a row of parallel ~ -~
fingers 108 and being formed integrally with a contact element ::
support 91, fits over the array of contacts 95 on the bed 97 with the fingers 108 thereof in the slots 112 of the base 99 :
(as shown in Figure 4), and with the edge 90 of the support 91, remote from the fingers 108, adjacent the shoulder 96 and with the terminals 1 extending through slots 109 in the support 91. ::
Separate contact elements 89 each comprise a pin recep- ~
tacle 102 connected by a cranked strip 86 to a conventional : -; 25 slotted plate terminal 84 having a single wire receiving slot 85.
The elements 89 are of overall shorter length than the elements '~9S. Each receptacle 102 rests upon the upper surface 88 of one of the flngers 108 as shown in Figure 4, with the strip 86 rec-eived in a slot 133 of the support 91, each slot 133 being po-sitioned between two slots 109, but being offset therefrom .
a~l4 ~06503~l towards the fingers 108.
An insulating cap 82 is mounted over the receptacles 102 so that each of the receptacles 102 is received in a recess 134 in the cap 82, as shown in Figure 4, which communicates with an aperture 101 in a forward wall of the cap, through which a male contact element in the form of a pin (not shown) can be inserted to mate with the receptacle 102. An insulating cover 135 (best seen in Figure 3) fits into the base 99, adjacent to the cap 82 : :
and has recesses 145 and 146 which receive the respective ter-minals 1 and 84 as shown in Figure 4.
The cap 82 is releasably secured to the ~ase 99 by inter-~ engaging latches 130 and bosses 121, on the cap 82 and base 99, the cover 135 being similarly secured to the base 99 by inter-engaging latches 137 and shoulders 138, on the cover 135 and the base 99.
Prior to the assembly of the cover 135, to the base 99, ~:
(see Figure 3) wires 28 and 30 of a multi-wire flat cable 147 (of the kind known as a "flat flexible cable") are selectively -inserted into the slots of the terminals 1, and 84, according .
to a desired wiring pattern for the connector, and may, or may not, as required, connect a contact element 95 to a contact ~ -element 89.
As will be apparent from Figures 4 and 5 the terminals ; 1 and 84 lie at the same level but in staggered relationship 25 so that wires can be loaded lnto the slots of these terminals --.
simultaneously and by means of a composite tool, whereas the receptacles 93 and 102 lie in superposed rows, with each rec- :
eptacle of one row exactly opposite to a receptacle of the other row.
- 30 According to Figures 6 and 7, a second electrical conn-, : ~ 7 ~
8~1~
-~065031 ector similar to that descrlbed above, comprises two comple~
mentary insulating housing portions 160 and 161 which are inter-matable with the interposition of an insulating spacer 162, these two portions being rotationally symetrical ~i.e. one S housing portion is a mirror image of the other).
Each porti.on 160 and 161 comprises two arrays of ele-ctrical contact elements 89' and 95' which are similar to the elements 89 and 95 described above excepting that the strips 86' of the elements 89' are not cranked as are the strips 86 of the elements 89 and are shorter than the strips 86. In the case of each housing portion 160 and 161, the elements 89' and 95' are arranged in alternation with one another on a flat bed 97' of the housing portion with their respective receptacles 93' and 102' positioned opposite pin receiving apertures 98' in a forward wall of the housing portion, the terminals 1' of the : .
elements 95' being nearer to a step 96' on the bed 97', than the terminals 84' of the elements 89', since the elements 89' are shorter than the elements 95'. An insulating member 92' .
covers each of the elements 89' and 95' and has slots 109' and 133' through which the terminals 1' and 84' respectively project as shown in Figure 7. The spacer 162 has spaced grooves 189 : and 192 receiving the respective terminals, also as shown in ; Figure 7.
Prior to the assembly of members 92' and the spacer 162, pairs of wires 170 of a multi-wlre flat cable 185 are forced in-to the bifurcated slots of each of the terminals 1' of each housing portion 160 and 161 (see Figure 6) and a wire 171 is forced into the single wire receiving slot of each terminal 84' after which the members 92' are assembled to the housing portions~: .
and these are releasably secured together about the spacer 162 - 8 - .:

In each of the two connectors described above, the slots of the terminals are of equal depth as measured from the surface of the bed 97 or 97' as the case may be.

106~031 having at its lower (as seen in Figure-l) end, a base in the form of a metal commoning strip 94 by which the terminal is connected to other and similar terminals tnot shown in Figure 1). The plate 2 has an upper (as seen in Figure 1) edge 6 in-to which opens a flared mouth 16 of a bifurcated wire receiving slot 8 formed in the plate 2. The mouth 16 communicates, in the inward direction of the slot 8 i.e. towards the base, with a parallel sided portion 14 of the slot, which in turn commun-icates in the inward direction of the slot 8, with two slot portions 18 and 20 which diverge in the direction of the base and between which lies a triangular portion 22 of the plate having a rounded apex 24 directed away from the base, the slot portions 18 and 20, in turn communicating in the inward direc-tion of the slot 8 with respective parallel slot portions 25 and 26.
` As shown in Figure 1, the width of the slot portion 14, which is constant, is greater than the diameter of either of metal wires 28 and 30 to be terminated by means of the terminal 1 but is of smaller width than the sum of the diameters of the wires 28 and 30, the width of each slot portion 18 and 20 being less than the diameter of either of the wires 28 and 30. The width of the slot portion 25 is l-ess than that of the slot por-tion 18, the width of the slot portion 26 being less than that of the slot portion 20. Although the slot portions 18 and 20 may decrease in width towards the base, it is essential that ~-their width at the apex 24 be less than the diameter of either of the wires 28 and 30.
In order to terminate the wires 28 and 30 by means of the terminal 1, these wires are inserted through the mouth 16 of the slot 8 into the slot portion 14 and are forced by means _ 4 _ . ~

Since the width of the slot portion 14 is less than the sum of the diameters of the wires 28 and 30, the wires are necessarily lie at different levels with respect to one another during their passage through the slot portion 14 as shown in Figure 1. As the tool 32 is advanced, the leading wire (28 in :
Figure 1) is diverted by the apex 24 into one of the divergent slot portions (the portion 1~ in Figure 1). The trailing wire (30 in Figure 1) is diverted by the leading wire into the other divergent slot portion (the slot portion 20 in Figure 1), since considerable force is needed to drive the leading wire into its lS divergent slot portion, in view of the restricted width of this portion and of its angle of divergence (approximately 20) with ~:
respect to the vertical. As the tool 32 is further advanced in the direction of the arrow A, each of the wires is forced from its divergent slot portion into the communicating parallel slot portion 25 or 26 as the case may be, where the wire is deformed to subtantially oval cross-sectional shape as indicated in broken lines in Figure 1, by virtue of the small width of the parallel slot portion, whereby permanent electrical contact is made between the wire and the plate 2.

with parallel slots 112 each communicating at one end with a tubular channel 98 and being defined by fingers 113 upstanding from a flat bed 97. A shoulder 96 projects from the bed 97 at a position spaced from, and opposite to, the end faces of the ~
fingers 113 remote from the channels 98. An array of electrical :
contact elements 9S rests upon the bed 97, each contact ele-ment 95 comprising a metal strip 111 having at one end a pin receptacle 93 and at the other end a terminal 1, these contact elements being commonly connected by strips 94 bridging the terminals 1. Each contact element 95 is positioned on the bed 97 with its receptacle 93 in one of the slots 112 and in align- ;
ment with a channel 98 through which a male contact member in the form of a pin (not shown) can be inserted to mate with the receptacle 93. These terminals 1 are positioned near the , 15 shoulder 96 as shown in Figure 4.
An insulating member 92 comprising a row of parallel ~ -~
fingers 108 and being formed integrally with a contact element ::
support 91, fits over the array of contacts 95 on the bed 97 with the fingers 108 thereof in the slots 112 of the base 99 :
(as shown in Figure 4), and with the edge 90 of the support 91, remote from the fingers 108, adjacent the shoulder 96 and with the terminals 1 extending through slots 109 in the support 91. ::
Separate contact elements 89 each comprise a pin recep- ~
tacle 102 connected by a cranked strip 86 to a conventional : -; 25 slotted plate terminal 84 having a single wire receiving slot 85.
The elements 89 are of overall shorter length than the elements '~9S.

An insulating cap 82 is mounted over the receptacles 102 so that each of the receptacles 102 is received in a recess 134 in the cap 82, as shown in Figure 4, which communicates with an aperture 101 in a forward wall of the cap, through which a male contact element in the form of a pin (not shown) can be inserted to mate with the receptacle 102. An insulating cover 135 (best seen in Figure 3) fits into the base 99, adjacent to the cap 82 : :
and has recesses 145 and 146 which receive the respective ter-minals 1 and 84 as shown in Figure 4.
The cap 82 is releasably secured to the ~ase 99 by inter-~ engaging latches 130 and bosses 121, on the cap 82 and base 99, the cover 135 being similarly secured to the base 99 by inter-engaging latches 137 and shoulders 138, on the cover 135 and the base 99.

2. An electrically conductive terminal in combination with a pair of wires of electrically conductive material to be electrically connected to the terminal, the terminal comprising a flat spring metal plate having a base, a marginal edge remote from the base and a wire receiving slot opening into the marginal edge and extending therefrom towards the base, the slot having a flared mouth defined by edges of the plate which converge from the marginal edge towards the base, a first portion communicating with the smaller end of the mouth and being defined by a pair of parallel edges of the plate spaced from one another by a distance which is less than the sum of the diameters of the wires and greater than the diameter of either wire, and two second portions each of which communicates at one end directly with the first portion, the two second portions diverging from one another in a direction away from the mouth and each having a maximum width which is less than the diameter of either of the wires, the two second portions being separated by a triangular portion of the plate having a rounded apex directed towards the mouth and being positioned at the junction between the first portion and the two second portions.
3. A terminal according to Claim 1 or 2, in which each second portion of the slot communicates directly with another por-tion of the slot, these other portions being parallel to one another and parallel to the edges of the first portion, the width of each such other portion of the slot being less than that of the second portion with which it communicates.
4. An electrical connector comprising a first row of slotted plate electrical terminals arranged on a flat surface of an insulat-ing base and a second row of slotted plate electrical terminals also arranged on the base in spaced, substantially parallel relationship with the first row, the terminals of one row being offset in the longitudinal direction of the rows with respect to the terminals of the other row, means retaining a multi-wire flat electrical cable in fixed relationship to the base with individual wires of the cable connected to the terminals of the rows and contacts on the terminals for mating with further contacts to be connected to the wires of the cable, each terminal of the first row defining a slot having a first portion capable of receiving two wires of the cable and two further portions, which are juxtaposed with one another but which diverge from one another in a direction away from the first por-tion and each of which communicates directly with the first portion, so that each wire when positioned to extend through such first por-tion can be moved laterally of the longitudinal axis of the wire into one of the second portions, the maximum width of the first por-tion of the slot being less than the sum of the diameter of the wires and greater than the diameter of either wire and the maximum width of each second portion of the slot, being less than the di-ameter of either wire.
5. A connector according to Claim 4, in which the slots of the terminals are all of equal depth as measured from the flat surface of the base.
6. A connector according to Claim 4, in which the contacts on the terminals of one row are arranged in superposition with those of the other row each contact of one row extending parallel to and opposite to a contact of the other row, the terminals of one row being connected to the contacts of the one row by means of elect-rically conductive strips which are of greater overall length than electrically conductive strips connecting the terminals of the other row to the contacts of the other row.
7. A connector according to Claim 6, in which an insulating member interposed between the contacts of the two rows has a first portion which covers the electrically conductive strips connecting the terminals of each row to the contacts thereof, these strips ex-tending along the flat surface of the base, the insulating member having a second portion provided with slots through which the ter-minals of the two rows project, a cover having a first portion provided with grooves receiving the ends of the terminals projecting through the slots and a second portion co-operating with the base to secure the cable.
8. A connector according to Claim 4, in which the contacts of the terminals of one row are arranged in alternation with the contacts of the terminals of the other row, the terminals of the one row being connected to the contacts of the one row by means of electrically conductive strips which are of greater overall length than electrically conductive strips connecting the terminals of the other row to the contacts of the other row, all the terminals and the strips, as well as all the contacts, being covered by a common insulating member having slots through which the terminals of the two rows project.
9. A connector according to Claim 8, which is mated with a further and similar connector with the interposition of an insu-lator which is received in a recess defined by the insulating mem-bers of the two connectors, the insulator being provided with grooves receiving the ends of the terminals which project from the slots in the two insulating members and the cables associated with the two connectors being secured in superposed relationship between a portion of the base of each connector.
