Description
ELECTRICAL CONNECTOR
FIELD OF INVENTION
The present invention relates to an electrical connector. Reference will be made in the specification to the use of the invention with respect to electrical cables. The patent specification describes this use but it is by way of example only and the invention is not limited to this use.
BACKGROUND OF THE INVENTION
Conventional electrical connections to cables with multiple conductors commonly require two steps. The first step is to cut and strip away the outer sheath insulation of a cable and then strip the insulation from the individual wires contained within the cable to expose the electrical conductors and make the wires ready for connection to an electrical connector. This is commonly achieved in the field using hand tools such as cutters and wire strippers. The second step is attaching the exposed conductor of the wires to a connector by twisting them and then screwing them down with a clamp to form the connection.
The use of tools like cutters for stripping cable and screw drivers for connecting and securing the conductor to a connector is time consuming especially when multiple connections are required. As well, forming an electrical connection requires skills and often a qualified electrician to handle live conductors and wires. These problems have been addressed in US5464352. The described in US5464352 has a hinged clamp which when closed applies a direct force on uninsulated wires into wire guide channels and slotted blade conductors to make a connection. The connector however does not accommodate a cored cable. The outer core insulation of the cable must still be stripped and the individual wires manually placed into the wire guide channels. The disadvantage is that several pre steps are required before the connector can be used.
The problems are also addressed in PCT/AU2012/000995, which describes the use of a cam to push the cable onto piercing connector elements. However, this device requires a tool to operate the cam so that sufficient force is applied to make the connection. -2 -

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference to Figures 1-14, there is shown an electrical connector 100 according to a first embodiment of the present invention. The electrical connector 100 has a main body 102 which is rotatably and removably attached to a second body portion 104. The main body 102 has hook portions 106 which are engageable with pivot portions 108 on the second body portion 104. The second body portion 104 is movable between an open position (shown in Figures 1-3) and a closed position (best seen in Figures 12-13).
The main body includes two contacts 110,112 angled towards each other. The two contacts 110,112 have planar portions and cutting edges 114,116. The planar portions in the direction of the cutting edges 114,116 are angled towards each other and towards a reference plane (not shown) located between the two contacts 110,112. The cutting edges 114,116 of the two contacts 110,112 get closer to each other towards the main body 102 and further apart away from the main body 102.
The two contacts 110,112 are electrically connected to an electrical connection in the form of an electrical cable 120. The electrical cable 120 can terminate in a plug (not shown) or an electrical device (not shown).
The two contacts 110,112 are adapted to cut into a cable in the form of a three cored electrical cable 124 (best seen in Figures 4-11) as the second body portion 104 moves from the open position to the closed position relative to the main 25 body 102.
The main body 102 also includes a piercing contact 122. The piercing contact 122 is adapted to cut into the three cored electrical cable 124 (best seen in Figures 4-11) as the second body portion 104 moves from the open position to the closed position relative to the main body 102.
The second body portion 104 has a cable seat 126. The three cored electrical cable 124 can be located in the cable seat 126. Having the second body portion 104 removably attachable to the main body 102 enables the three cored electrical cable 124 to be located in the cable seat 126 without requiring an end of the three cored electrical cable 124 to be passed through the electrical connector 100. After the -10 -three cored electrical cable 124 is located in the cable seat 126, the second body portion 104 can be attached to the main body 102.
The second body portion 104 includes securing portions 130. Securing portions 130 are adapted to secure the three cored electrical cable 124 in the cable seat 126. The second body portion 104 includes a protrusion in the form of a rib 132. The rib 132 causes the three cored electrical cable 124 to be secured via a friction fit when the second body portion 104 is in the closed position. The main body 102 includes a protrusion in the form of a rib 134. The rib 134 causes the three cored electrical cable 124 to be secured via a friction fit when the second body portion 104 is in the closed position.
The main body 102 has snap lock means 138 which engage with apertures 140 in the second body portion 104 in the closed position to secure the main body 102 to the second body portion 104. A tool such as a screwdriver (not shown) can be used to disengage the snap lock means 138 from the apertures 140 to enable the second body portion 104 to move from the closed position to the open position relative to the main body 102.
The second body portion 104 includes apertures 142. The apertures 142 are located between an outer surface 144 and the cable seat 126. The apertures 142 enable the second body portion 104 to be attached to a surface (not shown) using 20 fasteners such as screws (not shown).
With reference to Figures 4-8a there is shown the electrical connector 100 in the closed position with the second body portion 104 removed for clarity. Figures 68a have portions of the three cored electrical cable 124 cut away to illustrate the connection between the two contacts 110,112 and corresponding conductors 150,152 in the three cored electrical cable 124, as well as the connection between piercing contact 122 and conductor 154 in the three cored electrical cable 124.
As the second body portion 104 moves to the closed position relative to the main body 102, the two contacts 110,112 cut into the three cored electrical cable 124, contact the corresponding conductors 150,152, and urge the conductors towards each other. Having the planar portions of the two contacts 110,112 in the direction of the cutting edges 114,116 angled towards each other and the cutting edges 114,116 of the two contacts 110,112 get closer to each other towards the main body 102 ensures that an electrical connection is achieved between the two contacts 110,112 and the corresponding conductors 150,152. This is beneficial when the conductors 150,152 are solid core conductors.
The piercing contact 122 has cutting edge 123 which causes the conductor 154 to move to a side of the piercing contact 122 as the piercing contact pierced the three cored electrical cable 124 as the second body 104 moves from the open position to the closed position relative to the main body 102. This is beneficial when conductor 154 is a solid core conductor.
