Abstract
Description
- 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 lights and other electrical devices.
- Electrical power outlet sockets are a common form of electrical device which are used extensively in domestic and commercial buildings for providing outlets from which electrical appliances can be supplied with mains electrical power. An electrical power outlet socket may typically be installed in a lower region of a wall, and have socket receptacles for three plug pins corresponding to an active, 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 example, the electrical switching or fuse box of the building, and to other electrical power outlet sockets in the same region of the building. In order to provide a secure electrical connection between 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 engaged into secure electrical contact by screwing a contact screw into the contact opening to physically and electrically engage the exposed conductor portion. Although this is not a particularly difficult operation, it will nonetheless be very labour intensive and inconvenient if many electrical power outlets are to be installed. 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 complexity of operations required to make electrical connections to each electrical power outlet socket.
- Australian Patent No.
784,652 - 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.

- 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 an outer electrically insulative sheath to form the cable that is received in the passageway.
- Alternatively, the insulated conductors that are received in the passageway are in the form of one or more electrically insulated connecting wires which are separated by stripping away the outer sheath of a cable in which the or each connecting wire was previously located, and the cutting edges cut through the electrical insulation covering the wires only.
- In a particularly preferred form of the electrical connector of the invention, the movable press is pivotally movable between the first and second positions, although in other embodiments the press may be moved by pushing, sliding, punching or other application of force.
- The movable press preferably includes a curved pressing surface that, when in the first position, is spaced apart from the or each insulated conductor in the passageway, and when in the second position presses against the or each insulated conductor.

Figure 34 is a perspective view showing the engagement of two continuous flat cables with respective electrical connectors in the power socket ofFigure 32 . - The
electrical connector 10 shown inFigures 1 to 3 is of the kind having insulation displacement contacts that are adapted to make electrical contact with respective insulated conductors. Such insulated conductors may, for example, comprise cables formed of three linearly extending bundles of electrically insulated copper wire strands, each bundle covered by a respective electrical insulation covering having a functionally coded colour to form an insulated connecting wire, and the three insulated connecting wires enclosed by an outer electrically insulative sheath. Such cables may be flat cables, 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 ahousing 12, to opposed side walls of which is mounted a roller ormovable press 14. There is apassageway 16 between thepress 14 and afloor 18 of thehousing 12 for receiving threeinsulated conductors Figure 4 ) in the form of aflat cable 26. Extending upwardly through thefloor 18 are three cuttingedges passageway 16. Thepress 14 is, in this embodiment, pivotally movable about apivot point 33 between a first position (as shown inFigure 2 ) where it allows access of thecable 26 into the passageway 16 (in the direction shown by arrow A) and a second position (as shown inFigure 3 ) where it presses against thecable 26 and forces it against the cutting edges 28, 30, 32. The application of this force is through a curvedpressing surface 34 of thepress 14 which has three elongatedslots cutting edges pressing surface 34 against the cutting edges. By application of this force, the threecutting edges cable 26 and make separate electrical connections to the threeconductors cable 26 substantially simultaneously and longitudinally with reference to the direction of the conductors in thepassageway 16. Theslots - The
press 14 has anaperture 35 which can receive the tip of ascrewdriver 36 or other tool for applying the necessary force to enable movement between the first and second positions. Thetool 36 can be used to push thepress 14 into the first position to open thepassageway 16, and can be used to pull thepress 14 into the second position to close thepassageway 16. - The curved
pressing surface 34 varies along its length in its distance from thepivot point 33 of thepress 14, such that atlocation 38 along the surface, an initial light contact force is applied on thecable 26 and that force progressively increases as thepress 14 is pivoted towards its second position and the length of thepressing surface 34 in contact with thecable 26 is further from the pivot point and closer to the cutting edges 28, 30, 32. - As shown in
Figures 5 and 6 , each cuttingedge 28 cuts longitudinally through the middle or near middle of each bundle of electrically insulatedwire strands 40, forcing or piercing its way between 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 conductors. - Each cutting
edge 28 also cuts into its respective insulated conductor, and thus makes separate electrical connections to the three conductors of thecable 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 inFigures 7 and 8 is similar in structure, operation and function to theconnector 10, except that it is configured to make separate electrical connections to insulated conductors comprising separated insulated connectingwires round cable 58. For this purpose, extending upwardly from the floor of thehousing 60 are twowalls opposed side walls passageway 69 through which respective ends of the threeinsulated wires respective cutting edges 72 which are aligned longitudinally with thepassageway 69. - The
electrical connector 50 has three curved pressing surfaces separated by twogaps 70 therebetween, the gaps being aligned longitudinally with the twowalls slot 71 aligned longitudinally with arespective 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 longitudinally through the middle or near middle of each bundle of electrically insulated wire strands, and makes separate electrical connections to the three conductors substantially simultaneously, in the same manner as is achieved by the cutting edges of theelectrical connector 10. - The
junction box 80 shown inFigures 9 to 12 has a T-shapedhousing 82 for three self-contained electrical connectors located inrespective lobes housing 82. Two of thelobes other lobe 88 is aligned perpendicularly 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 theconnector 10, and has a pivotallymovable press 90, apassageway 92 between thepress 90 and afloor 94 of the respective lobe of thehousing 82, and threecutting edges floor 94 and aligned longitudinally with thepassageway 92. Each lobe has aside opening 102 for receiving into thepassageway 92 an end of a flat cable when thepress 90 is in the first position. Pivoting thepress 90 to the second position results in making separate electrical connections to the three conductors of the flat cable substantially simultaneously and longitudinally with reference to the direction of the conductors in thepassageway 92. - As shown in
Figure 12 , the three cutting edges of each electrical connector are conductively interconnected so that there is electrical continuity between all of the active terminals (denoted as A), between all of the earth terminals (denoted as E), and between all of the neutral terminals (denoted as N). - As shown in
Figure 13 , one of the lobes of thehousing 82 of thejunction 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 inFigures 14 to 18 is similar in structure, operation and function to thejunction box 80, except that it includes a pair ofcorner mounting flanges holes 116 for receiving threaded fasteners therethrough, and is configured to either receive into each passageway the respective ends of threeflat cables Figure 17 ) or receive into the two passageways that are aligned longitudinally a continuousflat cable 124 and into the other passageway the end of a flat cable 126 (as shown inFigure 18 ). This change in configuration is achieved by having aremovable separator plate 128 that normally forms a wall of the housing between the electrical connectors located inlobes separator plate 128 is slidably removed from its engaging tracks in the housing to provide a continuous passageway for receiving the continuousflat cable 124 which may supply mains power. - The high profile,
surface power socket 140 shown inFigures 19 to 31 (also known as a plug top) has ahousing 142 formed as two integrally connected portions, a first generallycylindrical portion 144 for receiving an electrical three pin plug and a second generallytetragonal portion 146 for mounting thepower socket 140 to a wall or like surface. - The
power socket 140 has a removableelectrical connector part 148 which is engaged to an internal mountingpart 150 of thesocket 140. Thepower socket 140 can also engage three insulated conductors in the form of a continuous flat cable 152 (seeFigures 29, 30 and31 ). - The removable
electrical connector part 148 does not include a plurality of cutting edges, but the cutting edges 154 are provided by the internal mountingpart 150 of thesocket 140, so that theparts electrical connector part 148 has ahousing 156, to opposed side walls of which is mounted a pivotallymovable press 158. There is apassageway 160 beneath thepress 158 and extending between opposed side openings of theelectrical connector part 148 for receiving the continuousflat cable 152. Thepress 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 afloor 155 of the internal mountingpart 150 and, when theelectrical connector part 148 is engaged thereto, are aligned longitudinally with thepassageway 160. - The
electrical connector part 148 has fourcorner feet side lock 172 for engaging the internal mountingpart 150. - The internal mounting
part 150 has fourguide surfaces connector part 148. The internal mountingpart 150 also has a spring loadedpush button 182 andslide tracks floor 155. The push button 182 (as shown inFigure 28 ) has aside catch 187. - The
electrical connector part 148 is engaged to the internal mountingpart 150 by firstly lowering it so that the fourcorner feet guide surface Figures 24 and26 ) and theside lock 172 pushes down on theside catch 187 of thepush button 182 until theconnector part 148 is supported on thefloor 155. Theelectrical connector part 148 is then slid along the floor in the direction shown by arrows B inFigures 26 and 27 so that the corner feet are located under the guide surfaces and theside lock 172 no longer pushes down on theside catch 187, whereby thepush button 182 springs back to its normal position and theside lock 172 is located alongside theside catch 187. In this engaged position (as shown inFigures 25 and27 ) theelectrical connector part 148 cannot be slid out from under the guide surfaces because of the obstruction to such sliding provided by theside lock 172 abutting theside catch 187 of thepush button 182. - When the
electrical connector part 148 needs to be disengaged from the internal mountingpart 150, say, for engaging the continuousflat cable 152 to thepower socket 140, thepush button 182 is pressed until theside catch 187 is located entirely below theside lock 172 and, whilst thepush button 182 is held in that position, theelectrical connector part 148 is slid out from under the guide surfaces in the opposite direction to that for engagement. Thepush button 182 is then released and theelectrical connector part 148 can be lifted from thefloor 155 of the internal mountingpart 150. - As shown in
Figure 29 , the continuousflat cable 152 is received inslots 162 formed in opposite ends of thehousing portion 146 and crosses thefloor 155 of the internal mountingpart 150 above the threecutting edges 154. Theelectrical connector part 148 is then engaged to the internal mountingpart 150 in the manner as described above (seeFigure 30 ), so that thecable 152 is received through thepassageway 160 when thepress 158 is in the first position. Pivoting thepress 158 to the second position results in the threecutting edges 154 making separate electrical connections to the three conductors of theflat cable 152 substantially simultaneously and longitudinally with reference to the direction of the conductors in the passageway 160 (seeFigure 31 ). - The low profile, wall mounted
power socket 200 shown inFigures 32 to 34 has ahousing 202 to which is fixedly mounted twoelectrical connectors electrical connectors electrical connectors web 208 between each connector housing so that eachelectrical connector flat cable electrical connectors electrical connector 10 described earlier are identified by the same numerals. - It will be readily apparent to persons skilled in the art that various modifications may be made in details of design and construction of the electrical connectors described above without departing from the scope or ambit of the invention.
- For example, the electrical connector of the present invention may have only one cutting edge aligned longitudinally 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 cutting edges that move between the first and second positions.
