Definitions

  • the present invention relates to the field of electrical tap connectors and, more particularly, to a tap connector assembly for coaxial cable networks.
  • Premises wiring typically carries voice, electronic data, and/or electrical power over one or more electrical conductors in a communications cable network.
  • Workstations situated at various locations are linked to the cable network by tap connectors.
  • the present invention relates to a tap connector assembly comprising, a connector housing, first and second signal carrying contacts carried by the housing and adapted to be electrically connected to signal carrying conductors of the first and second cables, respectively, a third grounding contact carried by the housing and adapted to be connected to conductive sheaths of the first and second cables, and the housing having a construction for receiving a mating connector, whereby the first, second, and third contacts are engaged by the mating connector when the mating connector is received to provide electrical connection of the first and second signal carrying contacts and the third grounding contact with the mating connector.
  • the present invention consists in a tap connection assembly as defined in claim 1.
  • Figs. 1, 2, 4, and 5 illustrate an electrical tap connector assembly.
  • the connector assembly is generally designated by reference numeral 10 and includes a receptacle tap connector 6 adapted to be incorporated into an electrical cable network, and a plug connector 8 mateable therewith to connect external apparatus into the cable network.
  • the connector assembly is particularly designed to provide access to a premises wiring system although it should be understood that it is not intended to restrict the invention to any particular application.
  • Receptacle tap connector 6 is adapted to connect two cables 12a and 12b in the cable network.
  • cables 12a and 12b include an outer jacket 21 of polymeric, insulative material coaxially and concentrically surrounding an electrically conductive grounding sheath 22.
  • Electrically conductive sheath 22 in turn, surrounds an insulative sheath 23 which contains the one or more transmission lines of the cables.
  • the transmission lines can include one or more electrical conductors and/or one or more optical fiber conductors.
  • the cables comprise coaxial cables carrying a single, signal carrying electrical center conductor 24 axially within the conductive outer sheath 22.
  • Receptacle tap connector 6 is illustrated in detail in Figs. 2-5 and is designed to be easily assembled and installed into a cable network without specialized tools or skills.
  • receptacle tap connector 6 includes housing assembly 14, a pair of fitting assemblies 16 and 17, and a signal carrying contact assembly 18.
  • Housing assembly 14 will be described in greater detail hereinafter, but generally comprises an elongated, molded plastic housing 30 having a central cavity portion 31 for receiving and supporting signal carrying contact assembly 18 and a grounding contact 19, and a pair of end portions 32 and 33 for receiving and supporting fitting assemblies 16 and 17, respectively, when the connector is assembled.
  • Fitting assemblies 16 and 17 are identical, and the same reference numerals are used herein to describe their construction.
  • Each fitting assembly comprises a molded plastic, bolt shaped fitting 41 having an electrically conductive member 42 attached thereto.
  • Fitting 41 has a central passageway 43 extending axially therethrough, and an internal shoulder 44 of the passageway divides the passageway into first passageway portion 43a and second, reduced diameter, passageway portion 43b.
  • Conductive member 42 comprises a relatively thin, metal member shaped to define a sleeve portion 46 and a flange portion 47.
  • the sleeve and flange portions have a central opening 49 passing therethrough which is adapted to be aligned with passageway 43 in fitting 41 when the two components are assembled. More particularly, and as best shown in Figs.
  • conductive member 42 is mounted to fitting 41 by extending sleeve portion 46 into passageway 43 until flange portion 47 contacts end face 51 of fitting 41. Following insertion, the end of sleeve portion 46 extending into passageway portion 43a is flared outwardly, as indicated at 46a in Figs. 3-5, by a suitable tool to secure conductive member 42 to the fitting while allowing the conductive member to freely rotate relative to the fitting.
  • Fitting assemblies 16 and 17 so constructed comprise clamping members and are adapted to receive the ends of cables 12a and 12b, respectively.
  • the cables Prior to insertion of the cables into the fittings, the cables are prepared by cutting and stripping off a length of their outer dielectric jacket 21 to expose a portion of braided, conductive sheath 22 therein. A lesser portion of the conductive sheath is also removed to expose inner dielectric sheath 23.
  • the cables so prepared are then inserted into and through passageways 43 of fittings 41 from ends 52 thereof and through openings 49 in conductive members 42.
  • Each of the fittings 41 includes an outer, threaded surface portion 56 for engagement with housing assembly 14 and a fluted portion 57 to provide an enhanced gripping surface for the worker to assist in insertion of the fitting assemblies into the housing assembly.
  • Fitting assemblies 16 and 17 are adapted to be inserted into and secured to end portions 32 and 33, respectively, of housing 30.
  • End portions 32 and 33 define recesses 71 and 72, respectively, which are internally threaded for attachment to threaded portions 56 of fitting assemblies 16 and 17, respectively.
  • Recesses 71 and 72 have back walls 74 and 75, respectively, having small central apertures 76 and 77, respectively (Fig. 3), therein for receiving center conductors 24 of the cables and their insulative coating 23, as shown in Figs. 4 and 5.
  • the housing is molded from an insulative plastic to define narrow slots 81 and 82 extending into cavities 71 and 72, respectively, adjacent back walls 74 and 75 thereof. These slots are adapted to receive disk like portions 91 and 92 of grounding contact 19.
  • Disk like portions 91 and 92 define second sheath engaging surfaces or clamping surfaces to be clamped against first sheath engaging surfaces 53 on flange portions 47 of conductive members 42 to clamp fanned out portions 22a of outer conductive sheaths 22 therebetween when fitting assemblies 16 and 17 are mounted to housing assembly 14.
  • Disk like portions 91 and 92 include central apertures 90 and 95 for receipt of center conductors 24 and their insulative sheaths 23 when the cables are extended into housing assembly 14.
  • disk like portions 91 and 92 of grounding contact 19 are of domed resilient spring configuration to provide stored spring energy to compensate for any creep characteristics of the plastic components when fitting assemblies 16 and 17 are screwed into ends 32 and 33 of housing 19.
  • the grounding contact also includes a central strip 98 connecting the disk like ends 91 and 92 and a center ground bar 99 positioned at right angles along one side of the strip.
  • the grounding contact is secured to the housing by four bosses 96 on the central strip (Fig. 2) which are pressed into the inner surfaces of the sides of molded housing 30.
  • Spring fingers 97 may also be provided on center ground bar 99 to engage a surface on housing 30 to further lock the grounding contact to the housing after the grounding contact is inserted into the housing.
  • disk like portions 91 and 92 When grounding contact 19 is inserted into housing 30, domed, disk like portions 91 and 92 extend into slots 81 and 82, respectively, such that disk like portions 91 and 92 are positioned within cavities 71 and 72 adjacent back walls 74 and 75 thereof. Center ground bar 99 extends through a slot 100 formed in the side of housing 30.
  • grounding contact 19 is first inserted into housing 30.
  • Fitting assemblies 16 and 17, having the ends of cables 12a and 12b, respectively, attached thereto, are then threaded into ends 32 and 33 of housing 30.
  • Fanned out braided portions 22a of outer sheaths 22 are sandwiched between sheath engaging surfaces 53 on contact members 47 and sheath engaging surfaces 93 and 94 on disk like portions 91 and 92.
  • domed disk like portions 91 and 92 collapse in a fashion similar to a bellville washer and are capable of recovering through spring action to an extent necessary to compensate for movement due to plastic creep of the threaded plastic elements.
  • the conductive sheaths of the cables are thus firmly clamped to the connector and electrically connected to grounding contact 19 therein.
  • Second clamping surfaces 93 and 94 on disk like portions 91 and 92 are preferably roughened to more firmly clamp fanned out conductive sheaths 22a thereagainst.
  • Such roughened surfaces can comprise, for example, a plurality of raised ridges or depressions on the surfaces.
  • Fig. 3 shows (in cross section) a plurality of circular ridges 151 on clamping surface 93, and a plurality of radial ridges 152 on clamping surface 94.
  • dielectric covered, but unshielded, signal carrying, center conductors 24 of cables 12a and 12b pass through holes 90 and 95 in disk like portions 91 and 92 of the grounding contact and into central cavity portion 31 of housing 30.
  • the cables thus also function to retain grounding contact 19 within housing 30 when the receptacle connector is fully assembled.
  • the covered center conductors pass over U shaped rib structures 101 and 102 formed in central portion 31 which support the covered center conductors and function as anvils for connection of the center conductors to signal carrying contact members as will be explained below.
  • a centrally located wall 106 extends across central cavity portion 31 and serves as a stop and a dielectric barrier to ensure that the center conductors entering the central portion of the housing from the opposite ends do not inadvertently contact one another. Housing assembly 14 is now ready to receive signal carrying contact assembly 18.
  • Signal carrying contact assembly 18 comprises a contact housing 121 of molded plastic and a pair of signal carrying contacts 122 and 123 supported within the housing.
  • center conductors 24 extend through narrow slot portions 134a and 134b of slots 131a and 131b to firmly clamp conductors 24 and reliably establish electrical contact between the contacts and the center conductors (see Figs. 8 and 9).
  • Insulation displacement contacts of the type utilized herein are known in the art and are disclosed, for example in U.S. Patent No. 3,617,983.
  • switch means 140 On the upper ends of signal carrying contacts 122 and 123 opposite slot means 131 and extending at right angles along one side of the contacts, are normally closed switch means 140 defined by switch arms 141 and 142. Switch arm 141 is fixed to contact 122 while longer switch arm 142 is movable with respect to contact 123. Switch means 140 is designed to provide a first signal path between signal carrying contacts 122 and 123 and, hence, between signal carrying conductors 24 of cables 12a and 12b.
  • Switch arms 141 and 142 include elongated embossment features 161 and 162 near their outer tips. Embossment features 161 and 162 are oriented to be at right angles to one another to describe a cross contact configuration when the switch arms are in contact with one another. Movable switch arm 142 is preferably formed in a preloaded condition such that when it is installed into the contact housing, movable arm 142 is in a somewhat flexed condition to ensure firm, reliable, electrical connection of the switch arms.
  • Signal carrying contacts 122 and 123 also include flat portions 163 and 164 formed as continuations of the U shaped portions.
  • Flat portions 163 and 164 define connection areas for contact terminals contained in mating plug connector 8 as will be explained below.
  • molded features 171 and 172 on contact housing 121 provide support for the signal carrying contacts; and curved contact portions 173 and 174 between the flat and U shaped portions of the contacts bear against the molded contact housing features to provide support during insulation displacement connection with the cables.
  • Insulation displacement connection occurs when signal carrying contact housing assembly 18 is inserted into the central cavity of connector housing 30.
  • the center conductors of the cables are received within tapered areas 133 of slot means 131 of the contacts.
  • cutting edges 132 cut through protective sheaths 23 of the cables and allow the thus exposed center conductors of the cables to pass into narrow portions 134a and 134b of the slots to electrically connect the center conductors to the contacts.
  • Anvils 101 and 102 in connector housing 30 and molded portions 171 and 172 in signal carrying contact housing 121 provide backup support during cutting of the insulative layer of the cable.
  • narrow slot portions 134a and 134b is such as to firmly and reliably retain center conductor wires 24 therein; and by providing slots in the two sides of each U shaped contact, even greater reliability is achieved.
  • plug connector 8 To tap into the cable network, plug connector 8 is inserted into recess or cavity 175 within signal receiving contact housing 121 of receptacle tap connector 6.
  • Plug connector 8 is connected to an electrical cable 176 having a conductive sheath 177, a pair of signal carrying, insulation covered conductors 183 and 184, and an insulation covered, third conductor 182.
  • the conductors 182, 183, 184 include corresponding conductive portions 182', 183', 184' connected to corresponding conductive terminals 186, 187, 188, each of the terminals having a blade configuration that is of the type disclosed in U.S. Patent No. 2,791,755.
  • the terminals 186, 187, 188 are mounted on an external surface of an insulative housing 181 of plug 8 and are oriented on housing 181 to face, respectively, signal carrying contacts 122, 123 and ground bar 99 of grounding contact 19. At least a portion of plug 8 and terminals 186, 187, 188 are constructed for removable insertion into a plug receiving opening or recess 175 of contact housing 121. Upon said insertion, housing 181 of plug 8 urges terminal 186 to engage compressibly and slidably impinge ground bar 99 to establish an electrical connection of conductive sheath 177 of plug 8 to conductive sheaths 22 of cables 12a and 12b (see Figs. 6 and 7.
  • housing 181 of plug 8 urges terminals 187 and 188 to engage compressibly and slidably impinge, respectively, flat surfaces 163 and 164 of signal carrying contacts 122 and 123 to establish a second signal path between the first and second signal carrying contacts through plug 8 (see Figs. 4 and 5). Cables 182, 183, and 184 are retained within plug connector housing 181 by known stuffer boxes 191, 192, and 193.
  • Plug connector 8 includes a latching member 201 having a portion 207 adapted to engage a latching surface 202 in contact housing 18 when the plug connector is inserted into the receptacle connector to retain the connectors in mated condition (see Figs. 6, 7, and 10).
  • Latch 201 includes an extended finger portion 203 to readily permit the plug connector to be disconnected from the receptacle connector when desired. Extended ribs 211 and 212 formed in contact housing 121 help guide the plug connector into plug receiving cavity 175 of the contact housing during mating.
  • Plug connector housing 181 is configured to define a cam surface 205 (see Figs. 9 and 10) on the lower outside corner thereof.
  • Cam surface 205 is positioned to engage movable switch arm 142 during mating of the connectors and to disengage it from switch arm 141 to interrupt the first signal path between signal carrying contacts 122 and 123. More particularly, during mating of the connectors, ground connection is first made between grounding contact center bar 99 and grounding contact terminal 186 on the plug connector to connect the conductive sheaths in cables 12a and 12b to grounding cable 182.
  • movable switch arm 142 is released by cam 205 and automatically returns back into contact with switch arm 141 to close switch means 140 and reestablish the first signal path between signal carrying contacts 122 and 123.
  • a tap connector assembly which maintains network integrity at all times.
  • the assembly includes a receptacle tap connector mountable to a coaxial cable network and which provides a first electrical signal path between two cables when the tap is not in use.
  • the assembly also includes a plug connector mateable with the receptacle tap connector, which, when mated interrupts the first signal path after establishing a second signal path between the two cables through the plug connector and external apparatus connected thereby to establish a series connection of the external apparatus into the network.
