Description

ELECTRICAL CONNECTOR
I
This application is based on the specification filed in relation to New Zealand Patent Application
Number 748104, the entire contents of which are incorporated herein by reference.
TECHNICAL FIELD
The present invention relates to an electrical connector for connecting or terminating an electrical cable.
BACKGROUND ART
When an electrician connects electrical cables together, for example when wiring a house or o building, or when connecting an electrical cable to an electrical fitting, the electrician must strip an insulating material away from one or more conductors of the cable, so that the conductors are exposed from the insulating material for connection to the fitting or other cable.
A common electrical cable for providing power, e.g. 240V/50Hz, is a thermoplastic sheathed (TPS) cable. A TPS cable comprises an outer sheath of polyvinyl chloride (PVC) covering one or more individual cables, each of which comprises a copper conductor and PVC insulating sheath. The copper conductor may be a single wire, or may comprise a number of strands, for example three strands twisted together.
To make a termination an electrician must strip back the outer PVC sheath to expose the individual core cables, and then additionally strip back the PVC sheath on each conductor. The :o outer sheath is a toughened PVC and can be difficult to remove. The stripping process can be time consuming, and additionally, stripping or cutting back the outer insulation and/or the insulation over each core can sometimes result in inadvertent damage to the conductor. Where a conductor is damaged, to safely and correctly terminate the cable, it is necessary to cut an end portion off the cable to remove the damaged part and begin the stripping process again.
US 4,091,233 discloses an electrical cable connector comprising a housing defining two receptacles each for receiving an electrical cable, and one or more conductive prongs in each receptacle. The prongs in one receptacle are electrically connected to corresponding prongs in the other receptacle. To connect two cables together, the end of each cable is inserted into one of the receptacles. Each prong is embedded into the cable as the cable is pressed into the receptacle, to contact a respective wire of the cable, to electrically connect the wires of the two cables together. The prongs extend from an end of the receptacle towards an opening of the receptacle and extend for a substantial portion of the length of the receptacle. To ensure a satisfactory electrical connection between the prongs and the associated cable wires, ideally
James & Wells ref: 310259AU each prong is embedded into the cable along the full length of the pin. However, pressing a long pin into a cable may be difficult, especially when there are multiple cores and corresponding pins, and where each conductive core comprises a multiple twisted-strand conductor held tightly in an insulating sheath.
It is an object of the present invention to address the foregoing problems or at least to provide the public with a useful choice.
All references, including any patents or patent applications cited in this specification are hereby incorporated by reference. No admission is made that any reference constitutes prior art. The discussion of any reference states what their authors assert, and the applicant reserves the o right to challenge the accuracy and pertinency of any cited document. It will be clearly understood that, although one or more prior art publications are referred to herein, this reference does not constitute an admission that any of these documents form part of the common general knowledge in the art, in New Zealand or in any other country.
DISCLOSURE OF THE INVENTION
According to one aspect of the present invention there is provided an electrical connector for an electrical cable with at least two insulated cores within an outer insulating sheath. The electrical connector comprises:
an insulating body comprising a receptacle to receive an end of the electrical cable including the insulating sheath,
Ό at least two electrically conductive pins within the receptacle, each pin having a lateral shoulder located in the receptacle and facing towards an opening of the receptacle and a pointed prong extending from the shoulder towards the opening to penetrate a cable and make an electrical contact with a side of an electrical conductor of the cable, and wherein the shoulder provides an end-stop or lateral contact surface to make an electrical contact with an end of the electrical conductor, and a dividing wall located within the receptacle at or adjacent an inside end of the receptacle distal to the receptacle opening and positioned between adjacent said pins within the receptacle.

BEST MODES FOR CARRYING OUT THE INVENTION
Figures 1 to 5 illustrate an electrical cable connector according to the present invention. The connector 1 comprises a body 2 formed from an insulating material, with a cavity or receptacle 3 at each end of the body 2. The receptacles 3 are aligned in a longitudinal direction of the connector and/or cables to be used with the connector, and in the illustrated embodiment are separated by a wall 4. The connector also comprises one or more electrically conductive pins, and in the illustrated embodiment, there are three pins to correspond with three insulated cores of a cable to be connected. Alternative embodiments may comprise one, two, three or more pins.
In the illustrated embodiment, each pin 5 comprises a central enlarged portion 5a and a pointed 30 prong 5b extending from the central portion at each end of the pin. Each prong extends into
James & Wells ref: 310259AU
2019219758 21 Aug 2019 one of the two receptacles. The pin enlarged portion 5a has a lateral dimension that is larger than a lateral dimension of the prongs 5b, so that each end of the enlarged portion presents a lateral shoulder 5c. For example, central portion 5a and prongs 5b have a circular cross section, and the diameter of the central portion is larger than the diameter of the prongs, such that each end of the central portion 5a presents an annular shoulder 5c. Each pin 5 is arranged so that lateral shoulder is exposed within the receptacle to present the shoulder 5c within the receptacle, facing towards the receptacle opening at the end of the connector 1. The lateral shoulder 5c may be flush with an inside end surface 3b of the receptacle 3. In the illustrated embodiment the lateral shoulder is located within the receptacle and spaced a distance from o the inside end surface 3b of the receptacle. The lateral shoulder 5c may be located within the receptacle at a distance of up to about 2mm from the inside end surface 3b of the receptacle, or up to about 1 mm from the inside end surface 3b of the receptacle, or a distance of about 0mm to 1mm from the inside end surface 3b of the receptacle, or about 0.5mm from the inside end surface 3b of the receptacle.
To electrically connect two cables together, an end of one cable is pushed into one of the two receptacles, and an end of the other cable is pushed into the other one of the two receptacles. The cable has an outer sheath covering three insulated cores. When a cable is pushed into the receptacle, each prong 5b is pressed into an inside of the sheath of a corresponding core of the cable to make an electrical contact with an electrical conductor of the core. With the cable fully Ό inserted into a receptacle, each prong is received inside a sheath of a corresponding core of the cable to make contact with a side of the conductor of the core.
As described above, the lateral shoulder of the pin is presented within the cable receptacle. The shoulder presents a lateral contact surface or end-stop against which an end of the core conductors can press, improving electrical contact between the pin and the cable core. This is 25 particularly useful when the core conductor comprises a multiple strand conductor, as the multiple strands can be spread radially outwards by the prong entering the core sheath, with ends of the strands making direct contact with the lateral shoulder. In some embodiments, the radial width of the lateral shoulder is greater than or approximately equal to a diameter of a single strand of the core conductor. Preferably the lateral shoulder presents a surface that is orthogonal to the longitudinal axis of the pin prong and/or the cable receptacle.
As shown in the illustrated embodiment, the pin extends into the receptacle along a portion of the length of the cable receptacle. Preferably as shown, the pin extends for less than 50% of the receptacle length, and more preferably substantially less than 50% of the length of the receptacle. For example, in the illustrated embodiment, the pin extends for about 25% to 33% 35 of the length of the receptacle. In the illustrated embodiment, the length of each cable receptacle is approximately 20mm. This pin length, together with the lateral shoulder, achieves
James & Wells ref: 310259AU a suitable electrical contact, while presenting a penetration depth into the cable that is not excessive, avoiding a high engagement force when pressing the cable into the receptacle. A prong diameter of 1 mm is suitable for engaging with a conductor size of 1 mm2 to 1.5mm2, however, this particular prong size should not be seen as limiting and is provided byway of example. In the illustrated embodiment, the prong has a diameter of 1mm extending from the shoulder 5c for a length of approximately 1 mm and then tapers to the point of the prong over a length of approximately 5mm, providing a prong length and therefore cable penetration depth of 6mm. The prong length and therefore a cable penetration depth may be approximately 4mm to 8mm, or about 5mm to 7mm. The illustrated connector is suitable for connecting 1.5mm2 three o core TPS cable to New Zealand Standard AS/NZS 5000.2 which is suitable for fixed wiring installation for power circuits in domestic, commercial and industrial situations.
The outside diameter of the annular shoulder is preferably larger than the outside diameter of the cable conductive core, to present a positive end-stop against which the conduct can engage. For example, for a conductor size of 1 mm2 or 1.5mm2, the outside diameter of the annular shoulder is preferably at least 1.5mm and more preferably greater than 2mm, for example 2.5mm. For a pin prong 5b diameter of about 1mm, an annular shoulder outside diameter of 2.5mm presents an annular shoulder or lateral surface 5c with a radial width of about 0.75mm.
The illustrated embodiment comprises a dividing wall 6 between adjacent pins 5 within the
Ό receptacle. The dividing wall 6 is positioned between adjacent pins 5 to ensure a cable conductor of one core of the cable does not contact an adjacent pin, avoiding a short circuit between adjacent cable cores. This is particularly beneficial where each pin 5 of the connector 1 includes a lateral shoulder 5c within the cable receptacle 3 as described above. Should a strand of the cable conductive core extend beyond an end of the core insulation and/or longer 25 than other strands of the core, pressing the cable into the receptacle 3 may result in the strand contacting the lateral shoulder 5c and being deflected laterally. The dividing wall 6 presents an insulating barrier between pins to prevent a strand that may be deflected laterally from contacting an adjacent pin.
The dividing wall 6 is located at or adjacent an inside end 3b of the receptacle 3 distal to the receptacle opening 3a. In the illustrated embodiment the dividing wall 6 extends from the inside end 3b of the receptacle. Preferably the wall 6 extends into the receptacle 3 by a distance greater than the distance that the central portion of the pin extends into the receptacle. For example, the dividing wall extends 0.5mm or greater beyond the lateral shoulder 5c of the pin. In the illustrated embodiment, the lateral shoulder is located 0.5mm from the inner end of the receptacle and the dividing wall extends 1mm into the cable receptacle. A leading end or edge 6a of the dividing wall is located between the pointed end 5d of the prong 5b and the lateral
James & Wells ref: 310259AU shoulder 5c. Preferably the dividing wall extends a short distance beyond the lateral shoulder.
If the dividing wall extends too far into the receptacle, the dividing wall can result in a significant interference with the outer sheath of the cable, making it difficult to press the cable sufficiently into the receptacle.
In the illustrated embodiment, the dividing wall 6 extends fully across the receptacle 3. The wall may be substantially planar as shown. Preferably the dividing wall 6 has a pointed leading edge 6a facing towards the receptacle opening 3a so that the dividing wall acts as a blade or knife, to cut into an end of the outer sheath as the cable is pressed fully into the cable receptacle 3. Alternatively or additionally, the dividing wall may not extend fully across the o receptacle, for example there may be a gap between the wall and a side of the receptacle, to provide a clearance for the outer sheath of the cable. In some embodiments, the dividing wall may be circular, coaxial with the pin.
The receptacle may be formed to correspond with an outer shape of the cable. For example, in the illustrated embodiment, in an end view the receptacle comprises three overlapping circular portions to correspond with the cores and outer sheath shape of a three core TPS cable.
The connector preferably includes a means to secure the cable within the recess. The illustrated embodiment includes a clamp to clamp each cable within the respective receptacle. The clamp is provided by a screw (not shown) received in a threaded bush 7. The screw is threaded into the bush 7 to press against a side of the cable, to clamp the cable in position Ό within the receptacle. Other alternative securing means may be provided, for example clips or barbs or adhesive.
The insulating body 2 is preferably formed from a plastics material, such as polycarbonate. The plastics material may include a flame retardant, such as VO flame retardant. An example plastics material is Wonderlite® PC-6710. The bushes are preferably made of a metal material 25 and are preferably over-mouled by the material of the body. Preferably outside surfaces of the bush provide projections to mechanically engage material of the body encapsulating the bush. The pins 5 are preferably moulded within the body 2 but may alternatively assembled to the body post moulding of the body. The pins are formed from a conductive material, such as copper or steel, or a copper alloy such as brass.
VARIATIONS
Alternative connector configurations may be provided to the configuration illustrated in Figures 1 to 5. By way of example, a number of alternative configurations are described below.
As shown in Figures 6A and 6B, a connector according to the present invention may be configured as an end termination 101 for connecting to and terminating an end of a cable. The
James & Wells ref: 310259AU connector 101 includes a cable receptacle 3 at one end of the body 2 only. The pin 5 comprises a lateral shoulder 5c located within the receptacle 3 and facing towards the receptacle opening 3a, and a pointed prong 5b extending from the lateral shoulder 5c towards the receptacle opening 3a, as described above in relation to the embodiment of Figures 1 to 5.
Where the connector 101 comprises a plurality of pins 5, the connector preferably comprises a dividing wall positioned between adjacent pins 5 to ensure a cable conductor of one core of the cable does not contact an adjacent pin, as described above with reference to the embodiment of Figures 1 to 5. A connector comprising one cable receptacle may comprise two or more pins electrically connected together, so that the connector can be used to electrically connect two or o more cores of a cable together.
Other cable connectors are possible. For example, the cable receptacles 3 may be arranged side-by-side within the body 2, with the opening 3a of both receptacles at one end of the connector body 2. The pin or pins 5 may be formed in a U-shape to extend between the two receptacles 3.
Figure 7 illustrates a further configuration for a connector 102 according to the present invention for connecting two cables to a single cable. The connector 102 comprises first cable receptacle 3(i), a second cable receptacle 3(ii) and a third cable receptacle 3(iii). The first and second cable receptacles are located at an end of the body 2 and the third cable receptacle at an opposite end of the connector body 2. Each pin 5 comprises a first prong 5b(i) extending Ό from a first lateral shoulder 5c(i) located in the first cable receptacle, a second prong 5b(ii) extending from a second lateral shoulder 5c(ii) located in the second cable receptacle, and a third prong 5b(iii) extending from a third lateral shoulder 5c(iii) located in the third cable receptacle, the first, second and third prongs electrically connected together. Preferably the connector 102 comprises cable clamps to clamp each cable in the respective receptacle and 25 dividing walls between adjacent pins, as described above with reference to the first connector embodiment 1.
The invention may also be said broadly to consist in the parts, elements and features referred to or indicated in the specification of the application, individually or collectively, in any or all combinations of two or more of said parts, elements or features.
Aspects of the present invention have been described by way of example only and it should be appreciated that modifications and additions may be made thereto without departing from the scope thereof as defined in the appended claims.
