Definitions
- This invention relates to electrical connectors and to electrical connection assemblies utilising_ such connectors.
- the connectors of the invention are designed to connect high voltage conductors, for example cables and bus bars to electrical equipment such as transformers, switchgear, motors and other units.
- high voltage in the context of this specification is meant voltages of 3.3 kv and over.
- Separable connectors for use with such cable usually comprise a moulding defining a tapered opening and a cable entering port.
- the tapered opening is designed to fit onto a plug, while the cable to be connected to the equipment connected to the plug has a terminal secured to the trimmed end of the cable, the terminal being received in the cable entry port.
- the entry port is then closed by a plug which mates with the remainder of the moulding.
- an electrical connector for use with voltages of not less than 3.3 kV, comprising a housing moulded from electrically insulating material, the housing being homogeneous and free from any electrically conductive screening material, and the housing defining a body section and a stem projecting from the body section; an inwardly tapering socket opening into the body section from one end thereof; and a conductive terminal within the housing, the terminal having a first part lying at the inner end of the socket and exposed to the socket and a second part extending into the stem of the housing; characterised in that the terminal is moulded in situ within the housing, with the second part of the terminal being in intimate contact with the material of the stem except for an end section of the terminal which projects beyond the end of the stem to form a conductor connection section.
- a connector according to the invention that this can be manufactured inexpensively when compared with the presently used complex termination systems, and that sockets can be designed to accommodate any given form of tapered bushing or plug on high voltage equipment to which the cable is to be connected. Furthermore, because the terminal has a conductor connection section that projects beyond the end of the stem and is thus readily accessible, the connector can be used in conjunction with any size or type of cable, bus bar or other conductor, and a reliable connection can be effected simply and rapidly. This renders the connector very much more versatile than presently used types of connector and connecting systems.
- the material is desirably also such that the connector can withstand a peak fault current of at least 8.75 kiloamperes followed by a symmetrical fault current of at least 3.5 kiloamperes for a period of one second.
- the material should preferably also be capable of use for extended periods at temperatures in excess of 90°C without significant degradation of the aforementioned electrical properties or of mechanical properties such as Shore hardness, tensile strength and percentage elongation at break. Examples of suitable materials are certain castable elastomeric polyurethanes rubbers and resins.
- the terminal may be of any suitable conductive material, for example copper.
- the cable connection section of the terminal may take any one of a number of forms.
- the section may be a solid end section having at least one flat face, a hole extending through the end section transversely to the face and being designed to receive a bolt by way of which a connecting lug on a cable or other conductor may be secured to the section. There is thus a simple bolted connection between the conductor and the connector.
- a solid end section of the terminal is designed to receive an external ferrule capable of being secured to the section and to the end of a conductor to be secured to the section.
- the conductor connection section of the terminal comprises an open region, for example a tubular section, into which the end of a conductor may be inserted, the region being deformable to secure the region onto the conductor.
- connection When a conductor is electrically and mechanically connected to the cable connection section, the connection isconveniently shrouded by an insulated sleeve surrounding the end part of the conductor and at least the end part of the stem of the housing.
- sleeves may, for example, be simple slip-over or elastic sleeves, sleeves of heat-shrinkable material or sleeves built by winding self-amalgamating tape around the joint. Sleeves of heat-shrinkable material are initially positioned loosely around the connection between the connector and conductor, subsequently being heat-shrunk into position after the electrical and mechanical connection is effected.
- the sleeve is required only around the region of the stem and cable end, in contrast to previous systems using heat-shrinkable sleeves which have surrounded not only the region just stated, but also the whole of the bushing and associated assembly forming the cable termination.
- the design and manufacture of appropriate heat-shrinkable sleeves is greatly simplified by the connector of the invention.
- the outer surface of the stem of the housing has at least one radial protrusion, which may preferably be in the form of a rib extending around the circumference of the stem. Such protrusions assist in anchoring the insulating sleeve in position on the connector.
- the form of the terminal within the body section of the housing and its relationship with the socket may be designed to suit the particular application for the connector.
- the terminal is curved within the body section of the housing, and the exposed part of the terminal projects into the socket from the inner end thereof and is coaxial with the socket.
- an auxiliary socket coaxial with the first said socket opens into the body section from a second end thereof, and the auxiliary socket has an inner end separated from the inner end of the first socket by the exposed part of the terminal.
- the basic embodiment of connector according to the invention provides a socket opening into said one end of the body section for receiving a single plug.
- the deceptively simple principle behind the invention does, however, make possible the provision of other forms of connector.
- two or more inwardly tapering sockets may open into the body section from a common end thereof, the axes of all sockets being parallel and the conductive terminal having parts lying at the inner end of each socket and exposed to each socket. If the stem of the housing is considered as being at the lower part thereof then multiple sockets may be arranged one above another and/or one alongside another.
- a single moulding can provide multiple outlet sockets connected to a single input conductor.
- each socket may have an associated auxiliary socket coaxial therewith, which auxiliary socket may, if required be closed by a plug.
- the housing may have an integral extension from the body section, at least one additional socket being formed in the extension and the terminal extending so that a further part thereof lies at the inner end of the or each additional socket.
- the axis of the or each additional socket need not be parallel to that of the first socket, and the or each additional socket need not be of the same shape as the first socket.
- the second end of the body section of the moulded housing is formed with a male tapered part engageable in a socket of another axially aligned connector. In this way, two or more conductors may be connected to a single input or output.
- the invention extends also to an electrical connection assembly comprising an electrical connector in any one of the forms previously set forth, a plug engaged in the or a socket of the connector and in electrical contact with the terminal, and a conductor electrically and mechanically connected to the cable connection section of the terminal.
- the connection between the conductor and the terminal is shrouded by an insulating sleeve surrounding the end part of the conductor and at least the end part of the stem of the housing.
- the sleeve may suitably be of a material such that it can be heat-shrunk into position after being positioned loosely around the connection.
- the moulded housing is of insulating material it may well not be safe to the touch, and care must obviously be taken in safeguarding access to the connector. Accordingly, the connectors will usually be located within a metal-enclosed cable box which is connected to earth. There is, of course, no need to fill the box with insulating compound, thus leaving the connectors fully exposed so that they. may readily be separated from the bushing or plug received in the socket, once power has been removed and the connector made electrically safe.
- an electrical connector comprising a moulded housing 1 defining a body section 2 and a stem 3 projecting transversely therefrom.
- An inwardly tapering socket4 opens into the body section from one end thereof and an inwardly tapering auxiliary socket 5 opens into the body section from a second end thereof.
- the two sockets are coaxial.
- a conductive terminal 6 is moulded in situ in the housing, the terminal having an exposed part 7 lying between and separating the inner ends of the socket 4 and of the auxiliary socket 5.
- the terminal passes through the projecting stem 3 and terminates at an outer end 8 forming a conductor connection section lying externally of the housing.
- the end 8 is solid and of rectangular cross-section.
- the terminal is provided with holes 9 and 10 respectively at its exposed part and conductor connection section, the hole 9 being coaxial with the sockets.
- the connector is moulded so that the socket 4 has a shape and size meeting recognised standards for high voltage separable connectors, and desirably so that the tolerances between the socket and a bushing or plug are such as to give a hermetically sealed' joint that will completely exclude ingress of moisture into the socket.
- the socket may be of any desired size or shape to suit the bushing or plug by way of which it is connected to the equipment concerned.
- the housing may conveniently be moulded from a flexible polyurethane elastomer formed from a resin that is a catalysed blend of polyether polyols containing dessicants and a chromium based inorganic pigment and from a hardener that is a prepolymerised form of diphenylmethane diisocyanate.
- the material exhibited the following properties.
- the comparative tracking index measured in accordance with I.E.C. Standard Publication 112:1979 after being newly cast and after ageing for 240 hours at 120°C was 110 v, using brass electrodes.
- the dielectric properties measured in accordance with British Standard 2782 were dielectric strength of 8.33 kv/mm, volume resistivity of 2.3 x 10" ohms and surface resistivity of 8.9 x 10 11 ohms.
- the dielectric loss angle (tan 6) at 20°C and 50 hertz was 0.015.
- FIG. 3 One normal method of use of the connector shown in Figures 1 and 2 is illustrated in Figure 3.
- the connector is slightly modified from that of Figures 1 and 2 in that the conductor 6 is of circular cross-section within the stem 3 of similar cross-section the upper and lower ends of the conductor being flattened in the connection regions.
- the connector forms an elbow connector capable of connecting a rising cable 11 to a tapered bushing or plug 12 capable of carrying an electrical load to any required equipment.
- the plug 12 is a mating fit within the socket 4 and seals onto the taper thereof.
- a silicone, petroleum or ester grease may usually be applied to the plug in order to ensure an airtight seal and prevent flashover or surface discharge.
- the end of the plug is formed with an internally threaded bore receiving a threaded stud 14 which passes through the hole 9 in the exposed part 7 of the terminal 6 and is engaged by a nut 15.
- a sealing plug 16 fits into the auxiliary socket, the sealing plug desirably being of insulating material which may be rigid when the housing is of flexible material.
- the plug has a threaded insert 16a engageable with the end of the stud 14.
- the nut 15 may be used either to draw the plug 12 into secure electrical contact with the terminal 6 or to release it from such contact, the sealing plug - insulating that contact area.
- the upper end of the cable 11 is suitably stripped and a connecting lug 17 is crimped or otherwise secured to the conducting core 18 of the cable.
- the lug has a flattened end 19 through which is formed an opening 20 which can be aligned with the hole 10 in the outer end of the terminal, the lug then being secured to the terminal by a suitable nut and bolt arrangement 21.
- a loose sleeve 22 of a heat-shrinkable material has been slipped over the free end of the cable. After effecting the connection the sleeve is pulled over the connection and over the stem 3 of the housing.
- the stem is formed with two circumferential ribs 23 (or other suitable form of radial protrusion) to assist in anchoring the sleeve 22.
- connection assembly as shown in Figure 3, the housing of the connector having been moulded from the flexible polyurethane elastomer previously described, was tested as follows.
- the assembly was placed in a sealed enclosure and subjected to an A.C. voltage of 12.9 kv for 1000 hours.
- the test water having a conductivity of 800 psiemens/cm was continuously sprayed onto the assembly at a rate of 4 Iitres/hr/m 3 . After the 1000 hours had passed the power was cut off and the connector inspected. No tracking has been experienced and no erosion of the housing was evident.
- a similar connection assembly was then immersed in a tub of water having a conductivity of 800 psiemens/cm.
- An A.C. voltage of 12.9 kv was applied and maintained for three weeks without any problems being experienced.
- the joint between the cable and the connector will generally be made before the socket is engaged with the plug 12.
- the working area around the joint is not constrained by a fixed location of the connector and application of heat uniformly to all regions of the heat-shrinkable sleeve is thereby facilitated.
- a similar degree of access and manoeuvrability is available for fitting sleeves other than heat-shrinkable sleeves, for example for building a sleeve by wrapping self-amalgamating tape around the joint.
- the plug may be formed with an integral flange and a sealing ring trapped between that flange and the face of the housing when the plug is tightened into electrical contact.
- the radially inner face of that socket may be provided with one or more circumferentially extending sealing rings, or with an annular sealing sleeve of suitable material. If the housing is rigid then the sealing plug will generally be of flexible material. Again, one or more sealing rings or a sealing sleeve may be incorporated in the auxiliary socket.
- Figure 5 shows a dead break elbow connector particularly designed to handle currents of up to 400 amps at 36 kv.
- the moulded housing defines a body section 31 and a stem 32 projecting transversely therefrom.
- An inwardly tapering socket 33 opens into the body section from one end thereof.
- a conductive terminal 34 is moulded in situ in the housing, the terminal extending through the stem and projecting therefrom to form a solid, circular cross-section end part 35 forming a conductor connecting section.
- Within the body section of the housing the terminal is curved as at 36 and it terminates in an exposed part 37 projecting into the socket 33 from the inner end thereof and coaxial with the socket.
- the projection 37 and socket 33 are designed to receive a standard circuit bushing for the design current.
- Figure 6 shows a connector 41 similar to that of Figure 5 but having a blade-like conductor connection section 42, with its socket engaged in position on a circuit bushing formed atthe end of a cable 43.
- the cable 43 has a collar 44 behind which is engaged a clip 45 from which extends a strap 46 of nylon or other non-metallic material, both ends of the strap being anchored to the clip 45.
- a wing nut 47 engages an internally threaded insert 48 moulded into the strap and engages a hardened pad 49 received in a recess 49a ( Figure 5) on the connector. The wing nut can be tightened to hold the connector firmly onto the bushing.
- FIG. 7 shows'in use an alternative embodiment of connector, parts of which have the same form as the connector of Figure 1 and are thus given the same reference numeral with the suffix b.
- the connector is moulded to have an integral extension 50 from the body section 2a and an additional socket 51 is formed in the extension.
- the material of the terminal 6b is extended at 52 to pass through the extension so that a part 53 thereof lies at the inner end of the additional socket 51.
- Additional equipment can thus be connected to an input cable 11b by a connection 54 cooperating with the socket 51, a sealing ring 55 being incorporated if required.
- the additional socket may be made of any required shape or size appropriate to the auxiliary equipment and its connecting means that will be associated with the auxiliary socket.
- Figure 4 also shows a sealing plug 15b having an integral internally threaded insert 56 engageable with the stud 14b of the plug, the sealing plug thus being used to effect anchoring of the plug. Obviously these two forms of anchorage are interchangeable. Furthermore, the sealing plug 15b also incorporates a screen 57 and means whereby the screen may be connected to a neon indicator. Similar plugs may be used in other of the illustrated embodiments.
- FIGs- 8 to 10 show alternative forms of connectors and in each case parts common to the connector of Figure 1 are shown by the same reference numerals in that Figure with the suffix c, d or e respectively for the three Figures.
- the connector shown in Figure 8 is moulded to have two inwardly tapering sockets 4c and 60 opening into the body section from one end thereof, the socket 60 being positioned above the socket 4c if the stem 3c is considered as lying to the bottom of the connector.
- the socket 60 has an associated inwardly tapering auxiliary socket 61 and the terminal 6c extends through the housing so that it separates the inner end of the socket 4c from the inner end of the auxiliary socket 5c and also the inner end of the socket 60 from the inner end of the socket 61. In the latter region the terminal is formed with a further hole 62 providing a connection point for a further plug that can be fitted into the socket 60.
- Figure 10 shows a straight-through connector whereby a bushing received in the socket 4e may be connected to a conductor secured to the end 8e of the conductor 6e, which extendsthrough a stem 3e coaxial with the socket 4e.
- each cable may be terminated to a connector of any suitable type shown, the connectors being in axial alignment.
- Adjacent connectors 70, 71 are in turn electrically connected to each other by a member 72 having male tapered parts 73, 74 at each end which may be received in - the facing auxiliary sockets of the connectors.
- a connector 75 may be moulded to have a socket 76 at one end thereof and a male tapered part 77 at the other end thereof.
- One cable 78 is secured to the terminal 79 of this connector 75 and a further cable 80 to the terminal 81 of a connector 82 similar to that shown in Figure 1.
- These junctions are each similar to the cable junction shown in Figure 3.
- the two connectors 75, 82 are axially aligned and the part 77 engages into the auxiliary socket 83 of the connector 82.
- a tapered circuit bushing 84 is received in the mains socket 85 and a threaded stud 86 extends through the terminal 81, through a conductive sleeve 87 in the connector 75, and through the terminal 79 to be secured by a nut 88.
- the socket 76 of the connector 75 is closed by an insulating sealing plug 89.
- the housing may be moulded from a rigid polyurethane elastomer, an EPDM rubber, a silicone rubber, an epoxy resin or a dough moulding material such as polyester glass, the material in each case having the required electrical properties and mechanical properties rendering them suitable for use in the connectors of the invention.
- the housing will be free of any screening material, despite the high voltage uses that are contemplated.
- the terminal rather than being of copper, may be of aluminium or other conductive material.
