COMPLETE SPECIFICATION
AN ELECTRICAL CONNECTOR WITH INSULATION
DISPLACEMENT CONTACTS
We Kolex Pty Ltd, Australia
company of 125 Albert Road. field New South Wales
2135, AUSTRALIA HEREBY declare the invention, for which
we pray that a patent be
granted to us and the method by which it is to be performed, to be described in and by the
following statement:-
AN ELECTRICAL TOR WITH INSULATION
DISPLACEMENT CONTACTS
FIELD OF INVENTION
The present invention relates to an apparatus and a method for making
electrical connection with an electrically insulated wire or cable and, in
particular, to an electrical connector with one or more insulation displacement
contacts that can be used in electrical power outlet sockets, electrical power
switches, electrical junction boxes, power transformers, ballasts for fluorescent
1O lights and other electrical devices.
BACKGROUND ART
Electrical power outlet sockets are a common form of electrical device
which are used extensively in domestic and commercial buildings for providing
s from which electrical appliances can be supplied with mains electrical
power. An ical power outlet socket may typically be installed in a lower
region of a wall, and have socket receptacles for three plug pins ponding
to an , a neutral and an earthing connection. Electrically insulated
connecting wires are installed within the building wall to connect the respective
contacts of the socket receptacles to the mains electrical power source at, for
2O example, the electrical switching or fuse box of the building, and to other
electrical power outlet s in the same region of the building. In order to
provide a secure electrical connection n the connecting wires in the wall
and the electrical contacts of the power outlet socket, screw contacts have
normally been utilised. A screw contact requires that insulation from an end of
the connecting wire be removed, and the exposed conductor portion of the wire,
consisting of a bundle of thin wire strands, be twisted and inserted in a contact
opening and then d into secure electrical t by screwing a contact
screw into the contact opening to physically and electrically engage the
/09/14
d conductor n. Although this is not a ularly difficult operation,
it will eless be very labour ive and inconvenient if many electrical
power outlets are to be led. It also requires the use of pliers, a stripper
and a screwdriver to carry out the cut, strip, twist, insert and screw operations.
Also, stripped insulation, which is normally made of PVC, will litter the vicinity of
these operations unless they are removed. It would be desirable, therefore, to
reduce the number and xity of operations required to make electrical
connections to each electrical power outlet socket.
Australian Patent No. 784,652 discloses an electrical connector which
addresses some of these problems by being able to effect relative movement
between the conductors and its insulation displacement contacts, the relative
movement being so restrained as to make the electrical connections
therebetween in a substantially sequential manner. That electrical connector
also requires that, for electrical tion to a doubly insulated cable, the outer
insulative sheath of the cable be first stripped or removed from a portion of the
cable and the thus revealed inner insulated wires be received in wire channels
of one part of the connector. That electrical connector also has its insulation
displacement contacts configured laterally with respect to the directions of the
insulated wires received in the channels, so that the insulated wires are'cut
cross-wise at an angle that, whilst g h the insulation, may also cut
through and sever the nearby wire strands, thus reducing the level of electrical
tion.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide an electrical connector
that achieves a faster, easier, safer, cleaner and/or more effective form of
electrical connection with insulated conductors in the form of a cable (which has
a double layer of insulation) or an electrically insulated connecting wire (which
has a single layer of insulation), than in the aforementioned prior art.
/09/14
ing to the ion there is provided an electrical connector
having one or more insulation displacement contacts adapted to make electrical
connection with respective insulated conductors in the form of a cable or an
electrically insulated connecting wire, the connector comprising:
(a) a eway for receiving the or each insulated conductor,
(b) one or more cutting edges of respective insulation displacement
contacts for cutting into a respective insulated conductor to make
electrical connection to the or each conductor when received in
the passageway, the or each cutting edge extending ly
through a floor of the passageway and being aligned longitudinally
with the passageway, and
(c) a movable press located adjacent to the passageway and pivotally
movable about a pivot point between a first position where it
allows access of the or each insulated conductor into the
passageway and a second position where it s against the
or each insulated conductor and forces the insulated conductor
against the respective cutting edge whereby the or each cutting
edge cuts into the respective insulated conductor and makes
electrical connection to the or each conductor longitudinally with
reference to the direction of the or each conductor in the
passageway.
In a preferred form, the ical connector has a plurality of cutting
edges which are aligned longitudinally with the eway, y the
g edges make separate electrical connections to tive conductors
substantiallysimultaneously.
Preferably, the insulated conductors that are received in the passageway
are in the form of a cable and comprise connecting wires separately covered
with electrical insulation, and the so insulated connecting wires are enclosed by
/09/14
an outer electrically insulative sheath to form the cable that is received in the
passageway.
Alternatively, the insulated tors that are received in the
passageway are in the form of one or more electrically insulated connecting
wires which are separated by ing away the outer sheath of a cable in
which the or each connecting wire was previously located, and the g
edges cut through the electrical insulation ng the wires only.
The movable press preferably includes a curved pressing surface that,
when in the first position, is spaced apart from the or each insulated conductor
1O in the eway, and when in the second position presses against the or
each insulated conductor.
The curved pressing surface preferably varies along its length in its
distance from the pivot point of the press, the distance of the curved pressing
surface from the pivot point varying such that, at a first location along the
curved pressing surface, an initial light contact force is applied on the tor
and that force progressively increases as the press is pivoted towards the
second position.

DETAILED DESCRIPTION OF INVENTION
The ical connector 10 shown in Figures 1 to 3 is of the kind having
insulation displacement contacts that are adapted to make electrical contact
with respective insulated conductors. Such insulated tors may, for
example, comprise cables formed of three linearly ing bundles of
electrically insulated copper wire strands, each bundle covered by a tive
electrical insulation covering having a functionally coded colour to form an
insulated connecting wire, and the three ted connecting wires enclosed by
an outer electrically insulative sheath. Such cables may be flat , in which
the three insulated wires are arranged in a straight line when the cable is
viewed cross—sectionally, or round cables, in which the three insulated wires are
arranged triangularly around a central point when the cable is viewed cross-
sectionally. Alternatively, such insulated conductors may comprise separated
insulated wires produced by stripping away the outer sheath of a round cable in
which the insulated wires were previously located.
The connector 10 has a housing 12, to Opposed side walls of which is
mounted a roller or movable press 14. There is a passageway 16 between the
/09/14
press 14 and a floor 18 of the housing 12 for receiving three insulated
conductors 20, 22, 24 (as shown in Figure 4) in the form of a flat cable 26.
Extending ly through the floor 18 are three cutting edges 28, 30, 32 of
copper blades which serve as insulation diSpIacement contacts or terminals for
active, earth and neutral conductors, respectively. The cutting edges are
aligned longitudinally with the passageway 16. The press 14 is, in this
embodiment, pivotally movable about a pivot point 33 between a first position
(as shown in Figure 2) where it allows access of the cable 26 into the
passageway 16 (in the direction shown by arrow A) and a second position (as
shown in Figure 3) where it presses t the cable 26 and forces it t
the cutting edges 28, 30, 32. The ation of this force is through a curved
pressing surface 34 of the press 14 which has three elongated slots 36, 38, 40
aligned udinally with the three cutting edges 28, 30, 32 so that each slot
receives therethrough its respective cutting edge as the cable is being forced by
the pressing surface 34 against the cutting edges. By application of this force,
the three cutting edges 28, 30, 32 cut into the cable 26 and make separate
electrical connections to the three conductors 20, 22, 24 of the cable 26
substantially simultaneously and longitudinally with reference to the direction of
the conductors in the passageway 16. The slots 36, 38, 40 ensure that the
cutting edges completely ate the insulated conductors by cutting through
the tion and piercing between the copper wire strands, y ing
optimum contact and conductivity for effective electrical connections.
The press 14 has an aperture 35 which can receive the tip of a
screwdriver 36 or other tool for applying the necessary force to enable
movement between the first and second positions. The tool 36 can be used to
push the press 14 into the first position to open the passageway 16, and can be
used to pull the press 14 into the second position to close the passageway 16.
/09/14
The curved ng e 34 varies along its length in its distance
from the pivot point 33 of the press 14, such that at location 38 along the
surface, an initial light contact force is applied on the cable 26 and that force
progressively increases as the press 14 is pivoted towards its second position
and the length of the pressing surface 34 in contact with the cable 26 is further
from the pivot point and closer to the cutting edges 28, 30, 32.
As shown in Figures 5 and 6, each g edge 28 cuts longitudinally
through the middle or near middle of each bundle of electrically insulated wire
strands 40, forcing or piercing its way n strands and thus substantially
maintaining the number of strands for optimal electrical connection, rather than
severing them and depleting the number of strands, as would be the case if the
cutting edges were arranged laterally with respect to the direction of the
tors.
Each cutting edge 28 also cuts into its respective insulated conductor,
and thus makes separate electrical connections to the three conductors of the
cable 26, substantially simultaneously, rather than sequentially, as the force
that is applied is substantially simultaneous on all conductors of the cable.
The electrical connector 50 shown in s 7 and 8 is similar in
structure, operation and function to the connector 10, except that it is configured
to make te electrical connections to insulated conductors sing
separated insulated ting wires 52, 54, 56 produced by stripping away the
outer sheath of a round cable 58. For this purpose, extending upwardly from
the floor of the housing 60 are two walls 62, 64 which, together with the
opposed side walls 66, 68, define therebetween three regions of a passageway
69 through which respective ends of the three ted wires 52, 54, 56 are
received. Extending upwardly through the floor of each such region of the
passageway are respective cutting edges 72 which are aligned longitudinally
with the passageway 69.
/09/14
The electrical connector 50 has three curved pressing surfaces
ted by two gaps 7O therebetween, the gaps being aligned longitudinally
with the two walls 62, 64, and each curved pressing surface has an elongated
slot 71 aligned longitudinally with a respective cutting edge 72. Each slot
receives therethrough its respective cutting edge as the cable is being forced by
the pressing surfaces against the cutting edges. Each cutting edge cuts
udinally through the middle or near middle of each bundle of electrically
insulated wire strands, and makes te electrical connections to the three
conductors substantially simultaneously, in the same manner as is achieved by
1O the cutting edges of the electrical connector 10.
The junction box 80 shown in Figures 9 to 12 has a T-shaped housing 82
for three self—contained electrical connectors located in respective lobes 84, 86,
88 of the housing 82. Two of the lobes 84, 86 are aligned longitudinally and the
other lobe 88 is aligned dicularly to the longitudinally aligned lobes.
The electrical connectors are identical to each other in structure,
operation and function. Each connector of the junction box 80 is similar to the
connector 10, and has a pivotally e press 90, a passageway 92 between
the press 90 and a floor 94 of the respective lobe of the housing 82, and three
cutting edges 96, 98, 100 extending upwardly through the floor 94 and d
longitudinally with the passageway 92. Each lobe has a side g 102 for
receiving into the passageway 92 an end of a flat cable when the press 90 is in
the first position. Pivoting the press 90 to the second position results in making
separate electrical connections to the three conductors ofthe flat cable
substantially simultaneously and longitudinally with reference to the direction of
the conductors in the eway 92.
As shown in Figure 12, the three cutting edges of each ical
connector are conductively interconnected so that there is electrical continuity
between all of the active als (denoted as A), between all of the earth
/09/14
terminals (denoted as E), and n all of the neutral terminals (denoted as
As shown in Figure 13, one of the lobes of the g 82 of the on
box 80 may be configured to locate an electrical connector (such as a wall
mounted light switch assembly) that differs from the other electrical connectors
in its application by making separate electrical connections to two active
conductors 104 of a cable or of respective insulated conductors comprising
separated insulated wires.
The junction box 110 shown in Figures 14 to 18 is similar in structure,
1O operation and function to the junction box 80, except that it includes a pair of
corner mounting flanges 112, 114 having holes 116 for receiving threaded
fasteners therethrough, and is configured to either receive into each
passageway the respective ends of three flat cables 118, 120, 122 (as shown in
Figure 17) or receive into the two passageways that are aligned longitudinally a
uous flat cable 124 and into the other passageway the end of a flat cable
126 (as shown in Figure 18). This change in configuration is achieved by
having a removable separator plate 128 that normally forms a wall of the
g n the electrical connectors located in lobes 84, 86. When
required, the separator plate 128 is slidably removed from its engaging tracks in
the housing to provide a continuous passageway for receiving the continuous
flat cable 124 which may supply mains power.
The high profile, surface power socket 140 shown in Figures 19 to 31
(also known as a plug top) has a g 142 formed as two integrally
connected portions, a first generally cylindrical portion 144 for receiving an
electrical three pin plug and a second generally tetragonal portion 146 for
mounting the power socket 140 to a wall or like surface.
The power socket 140 has a removable electrical connector part 148
which is engaged to an al ng part 150 of the socket 140. The
/09/14
power socket 140 can also engage three insulated conductors in the form of a
continuous flat cable 152 (see Figures 29, 30 and 31).
The removable ical connector part 148 does not e a plurality
of g edges, but the cutting edges 154 are provided by the internal
mounting part 150 of the socket 140, so that the parts 148 and 150 together
form an electrical tor according to the present invention. The electrical
connector part 148 has a housing 156, to opposed side walls of which is
mounted a pivotally movable press 158. There is a eway 160 beneath
the press 158 and extending between opposed side openings of the electrical
connector part 148 for receiving the continuous flat cable 152. The press 158 is
able to pivot between first and second positions in a manner as described
earlier with reference to other embodiments of the invention.
The three cutting edges 154 extend upwardly through a floor 155 ofthe
internal mounting part 150 and, when the electrical connector part 148 is
engaged thereto, are d longitudinally with the passageway 160.
The electrical connector part 148 has four corner feet 164, 166, 168, 170
and a side lock 172 for engaging the internal ng part 150.
The internal mounting part 150 has four guide surfaces 174, 176, 178,
180, on the same sides of which are gaps for receiving respective corner feet of
the connector part 148. The internal mounting part 150 also has a spring
loaded push button 182 and slide tracks 184, 186 on opposite sides of the floor
155. The push button 182 (as shown in Figure 28) has a side catch 187.
The electrical connector part 148 is engaged to the internal mounting
part 150 by firstly lowering it so that the four corner feet 164, 166, 168, 170
enter the gaps beside each guide surface 174, 176, 178, 180 (as shown in
Figures 24 and 26) and the side lock 172 pushes down on the side catch 187 of
the push button 182 until the connector part 148 is supported on the floor 155.
The electrical connector part 148 is then slid along the floor in the ion
/09/14
shown by arrows B in Figures 26 and 27 so that the corner feet are located
under the guide surfaces and the side lock 172 no longer pushes down on the
side catch 187, whereby the push button 182 springs back to its normal position
and the side lock 172 is located alongside the side catch 187. In this d
position (as shown in Figures 25 and 27) the electrical connector part 148
cannot be slid out from under the guide surfaces because of the obstruction to
such sliding provided by the side lock 172 abutting the side catch 187 of the
push button 182.
When the electrical tor part 148 needs to be disengaged from the
1O internal mounting part 150, say, for engaging the continuous flat cable 152 to
the power socket 140, the push button 182 is pressed until the side catch 187 is
located entirely below the side lock 172 and, whilst the push button 182 is held
in that position, the ical connector part 148 is slid out from underthe guide
surfaces in the opposite direction to that for engagement. The push button 182
is then released and the electrical connector part 148 can be lifted from the floor
155 of the internal mounting part 150.
As shown in Figure 29, the continuous flat cable 152 is received in slots
162 formed in opposite ends of the housing portion 146 and crosses the floor
155 of the internal mounting part 150 above the three cutting edges 154. The
ical connector part 148 is then engaged to the internal mounting part 150
in the manner as described above (see Figure 30), so that the cable 152 is
received through the passageway 160 when the press 158 is in the first
position. Pivoting the press 158 to the second on results in the three
cutting edges 154 making separate electrical tions to the three
conductors of the flat cable 152 ntially simultaneously and longitudinally
with reference to the direction of the conductors in the passageway 160 (see
Figure 31).

The low profile, wall mounted power socket 200 shown in s 32 to
34 has a housing 202 to which is fixedly d two electrical connectors 204,
206. The structure, operation and function of the electrical connectors 204, 206
are similar to that of the electrical connectors described with reference to earlier
embodiments. The ical connectors 204, 206 are located side by side but
with a gap therebetween created by a connecting web 208 between each
tor housing so that each electrical connector 204, 206 can receive the
end of a respective flat cable 210, 212. Features of the electrical connectors
204, 206 that are the same as features of the electrical connector 10 described
earlier are identified by the same numerals.
It will be readily apparent to persons skilled in the art that s
modifications may be made in details of design and construction ofthe ical
connectors described above t departing from the scope or ambit of the
invenfion.
For example, the electrical connector of the present invention may have
only one cutting edge aligned udinally with the passageway, and the
movable press may be moved by sliding, punching or other application of force.
In other alternative forms, the electrical connector may, rather than
having the press being movable relative to the stationary cutting edges in the
passageway, instead have the one or more cutting edges being movable
relative to stationary pressing surfaces of a press, so that it is the movable
g edges that move between the first and second positions.
