Definitions

  • ABSTRACT A junction box for the termination tapping or splicing or electrical conductors is formed of three interleaved portions; a cover portion, an intermediate portion and a base portion. Mounted upon one surface of the intermediate portion are a plurality of conductor connectors each capable of receiving electrical conductors without piercing the insulation thereon and making electrical contact therewith. Such connectors are provisioned for receiving and making electrical contact with additional electrical conductors having terminal thereon such as to provide a conductive path between conductors within the insulation piercing portion and that created by a terminal.
  • Straining relief means are provided adjacent the'free ends of the conductors place in the insulating piercing portion of the connectors for holding and aligning such conductors prior to, during, and after the insulation piercing operation has taken place. Additional straining relief devices may be provided adjacent the entry to the conductor connectors so that unwanted removal of the conductors from such connectors may not be made.
  • the invention is directed to the field of terminating, tapping or splicing electrical conductors principally within the telephone industry and more particularly to telephone junction boxes for joining the electrical conductors of a telephone hand set with incoming electrical lines.
  • the invention also finds utility in any field where it is desirable to terminate, tap or splice electrical conductors. r
  • the present invention seeks to overcome the difficulties noted above with respect to prior art junction boxes by providing a simple, easily assembled and applied device composed of three hinged portions which may be interleaved for final assembly of the junction box and which provides the necessary functions of strain relief for all conductors placed within such junction box and which permits the positioning, alignment and insulation piercing of certain conductors placed therein and the mating together with other conductors previously terminated with electrical terminals.
  • the entire assembly is provided with means in its base portion for securing the same to a mounting surface either by means of an adhesive layer affixed to the bottom of the base portion or by means of apertures in such base portion for the receipt therethrough of fastening means.
  • the cover portion provides overall dust protection as well as protecting the individual components and assemblies of electrical conductors within 'the junction box.
  • the intermediate portion has conductor connectors which provide all necessary insulation piercing for the insulated conductors and provides a simple means of mating together the conductors whose insulation has been stripped to other conductors having terminations in the form of terminals affixed thereto.
  • Each of the conductor connectors are fabricated of elongate pieces of flat, thin conductive resilient metal folded to form a generally L-shaped element having two distinct arms, a first of which is bifurcated to at least two legs, creating an insulation piercing channel into which an insulated conductor may be forced to pierce the insulation thereabout to form a mechanical and electrical contact therewith.
  • the second arm of the conductor connector provides spring fingers which can be displaced by an electrical terminal placed thereunder to retain and make electrical contact with such terminal thereby permitting a conducting path to be created between the terminated conductor and the conductor whose insulation has been pierced by the first arm of the conductor connector.
  • a series of strain relief combs on the intermediate portion permit the'conductors which enter the junction box to be fanned out and displayed thereby facilitating the matching of conductors of similar color coding. Strain relief is also provided at the entrance of such conductors into the junction box to prevent unwanted removal therefrom.
  • the hinged mounting of 1 the intermediate portion with respect to the base portion and the provision of a selectively operable lock between the base portion and the intermediate portion insures that the insulated conductors are-positively forced within the insulation piercing channels of the conductor connector to insure the proper piercing of the insulation of the conductors and the establishment of good electrical contact. It is therefore an object of this invention to provide an improved junction box.

  • FIG. 7 shows the junction box 20 in its open most condition.
  • intermediate portion 24 is folded over the base portion 22 and covered over by means of a cover 26.
  • Electrical cable 28, extending from the telephone hand set, is introduced through an aperture (partially visible in FIG. 7) to the interior of the junction box 20 where it is mated, in a manner to be described below, to the conductors of a feed cable 30 introduced through an aperture 32 within a side wall 34 of the base member 22.
  • a layer of adhesive material 36 which may be in the form of a pressure sensitive adhesive, with release paper thereover, a heat activated or otherwise activated adhesive, is placed along a bottom surface of the base portion 22 for adherance of the junction box 20 to a mounting surface, for example, a wall.
  • a series of apertures 38 may be placed within a base portion 22 for the passage therethrough of fasteners (not shown) for securing of the junction box 20 to a mounting surface.
  • Each of the conductors of the cables 28 and 30 are color coded in accordance with the various functions that the individual conductors are to serve. Thus it is necessary to match the color codings of the conductors within the cable 28 to that of the conductors within the cable 30.
  • a selectively operable latch member 40 is provided on the cover portion 26 for suitable engagement with the receiver portion 42 mounted upon the base portion 22.
  • cover portion 26 has a bifurcated latch member 40 (see FIG. 4) having inclined faces 44 and a locking flat 46 (see FIG. 3).
  • Latch member 40 is bifurcated to permit passage of the cable 28 therethrough without interfering with the latching function of latch member 40.
  • the receiver 42 as seen in FIG. 2, is bifurcated as well to permit passage of the cable 28 therethrough without interfering with the function of the latch member 40.
  • the inclined faces 44 of the latch member 40 cause the latch member 40 to be slightly deflected until such time as the locking flat 46 is adjacent the bottom surface of the receiver 42, at which time latch member 40 deflects outwardly again to prevent the separation of the latch member 40 from the receiver 42.
  • Hinge 48 is provided between the base portion 22 and the cover portion 26 to prevent unwanted separation of these parts during assembly.
  • junction box 20 Mounted on the internal surface 50 of the base portion 22 are two transverse ribs 52, 54 which provide therebetween a recess 56 the function of which will be described in greater detail below.
  • Mounted on the end wall 58 of base portion 22 are two arcuate partitions 60 separated by means of a space 62 sufficiently large to accept therethrough the cable 28.
  • the combination of the two arcuate partitions 60 and end wall 58 provide strain relief for the cable 28 which has been provided with a strain relief collar, as is widely done in the telephone industry.
  • FIG. 9 there is shown a portion of a cable 28 having affixed thereto a strain relief collar 64 of the type noted.
  • the collar 64 has a barrel portion 66 having an open seam 68 which is closed about a cable such as the cable 28 and because of this arrangement can accept therein cables of various diameters.
  • Affixed I at one end of the barrel portion 66 are ears 70 extending outwardly from the longitudinal axis of the barrel 66.
  • cable 28 is made up of four conductors 72, 74, 76 and 78.
  • the separate conductors 72, 74, 76 and 78 are colored coded so that their function is readily apparent to the telephone installer.
  • a typical color coding would be to have one of the conductors 72, 74, 76 or 78 yellow, another green, another red, and the final one black. Yellow, for example, designating the line which will be connected to the bell circuit of the telephone hand set.
  • the cable 30 is similarly made of four conductors, 80, 82, 84 and 86, (See FIG. 6) similarly color coded to identify the functions they are to serve. Each of the conductors 80, 82, 84, and 86 (See FIG. 7) is introduced about a strain relief post 88, across a conductor connector 90 to a further strain relief recess 93 and along the opposite side of the intermediate member 24. The excess portion of the conductors 80, 82, 84 and 86 are cutoff to prevent interference with the functioning of the junction box (see FIG. 6).
  • the conductor connector 90 is shown in greater detail in FIGS. and 11 to which reference is now made.
  • the conductor connector 90 is fabricated from an elongate piece of flat, thin, conductive and resilient metal formed in a generally L-shape (as is better seen in FIG. 11) having vertically extending arm 92 which is bifurcated as at 94 and 96 to provide two insulation piercing channels 98 and 100.
  • the edges defining the channels 98 and 100 are sharp so that they may pierce through the insulation of a conductor as the conductor is forced within the insulation piercing channels 98 and 100.
  • the width of the respective channels 98 and 180 will be less than the diameter of the conductor itself and therefore less than the diameter of the insulated conductor inserted therein.
  • the walls adjacent the channels 98 and 100 are tapered as at 102 to facilitate the entry of conductors within the channels 98 and 100 and to correctly position the conductors in these channels.
  • the arm 92 is so proportioned that it will be received between the upstanding transverse ribs 52, 54 of the base member 22 and fit within the recess 56 as is shown in FIG. 12. In this manner, conductors partially placed within the channels 98 and 100 will be forced further into these channels to insure the piercing of the insulation as the intermediate member 24 is assembled with the base member 22.
  • a conductor 80 has been positioned in a channel of arm 92, which in turn is positioned between ribs 52 and 54 defining recess 56.
  • a tab 104 extends from below the arm 92 for insertion through an appropriate aperture within the intermediate portion 22, as is shown in FIG. 1 1, whereupon the tab 104 may be suitably staked to the underside of the intermediate portion 24 to secure conductor contact 90 to the intermediate portion 24.
  • a second arm 106 extends generally horizontally with respect to the intermediate portion 24 and is bifurcated to provide fingers 108 as is better seen in FIG. 10.
  • the bifurcated fingers 108 terminate in upturned ends 1110 to facilitate the sliding thereunder of the terminals of the individual conductors 72, 74, 76 and 78 of the cable 28,to retain and make electrical contact with such terminals.
  • the terminals will be placed in positions along the top surface of the intermediate portion 24 between such top surface of intermediate portion 24 and spring fingers 108 of the second arm 106. Electrical contact will thus be established between the conductors terminated by means of the terminals and placed under the bifurcated fingers 108 and the conductors placed within the insu- Iation piercing channels 98 and 100 of the vertical arm 92.
  • a length of cable 30 has its outerinsulation stripped from it to expose the conductors 80, 82, 84 and 86.
  • Each of the conductors is then fed around an individual one of the strain relief posts 88 into one of the channels 98 or 100 of the conductor contact 90, and then placed into the strain relief recesses 93.
  • a second conductor of a similar cable might be introduced through a further aperture 32 in the opposite side wall of the base portion 22 and in a similar manner positioned about the strain relief post 88 and then into the free insulation piercing channel 98 or 100 of the conductor connector 90 and then into the aligned strain relief recess 93 associated therewith.
  • strain relief recesses 93 will serve to hold the respective conductors 80 through 86 in their desired positions until intermediate portion 24 is fastened to the base portion 22 in a manner to be described.
  • Latching of the intermediate portion 24 to the base portion 22 is achieved by means of a latch button 112 mounted adjacent hinge 48 of the base portion 22 and a latch 114 on the extreme opposite end of the intermediate member 24, as is shown in FIG. 7.
  • Latch 114 will be of the type having an inclined front face with a 7 flat top locking portion.
  • the latch 114 Upon the downward movement of the intermediate portion 24, the latch 114 will be displaced by the latch button 112 until the flat portion of latch 1114 passed the latch at which time the latch 114 will be permitted to return to its normal position and the flat top locking preventing the unwanted disassembly of the intermediate portion 24 with respect to the base portion 22.
  • the latch 114 may be separated from the latch button 112 by mere lateral movement in either direction of the intermediate portion 24 with respect to the base portion 22.
  • the coloring of the portion of the conductors of the cable 30, which are positioned within the strain relief recesses 93 and the coloring of the individual conductors of the cable 28 it is readily apparent whether or not a proper connection has been made between the respective conductors of the cables 28 and 30.
  • the cover portion 26 may be folded about its hinge 48 in a manner such that the latch member 40 of the cover portion 26 is caused to engage the latch receiver 42 of the base portion 24 to prevent unwanted separation of the portions of the junction box 20.
  • Cover portion 26 provides environmental protection for the junction box to prevent dust or other undesired objects from entering the junc tion box 20 and interfering with the operation thereof. If it is desired, the cover portion 26 may be omitted in those circumstances where such protection is not necessary.
  • terminal strips may be fabricated in such a manner that a number of the individual intermediate portions 24 be placed along the terminal strip having a common base portion and a common cover portion so that a plurality of the conductors may be joined as it is desired.
  • Cover 126 has its front wall 128 extended into a latch member 130 having an inclined front face 132 and a flattened portion 134.
  • Base portion 136 is provided with extending latch receiving arms 138 which overlie the flattened portion 134 of the latch member 130 of cover portion 126.
  • the latch member 130 will be deflected inwardly as the inclined face 132 passes the front face of the latch receiver 138 until such time as the flat portion 134 of the latch member 130 is opposite the bottom, horizontal edge of the latch receiving member 138. At this time, the latch member 130 will be permitted to be deflected to the right of FIG.
