CABLE SPLICE CLOSURE

Abstract: A closure (10) for receipt and storage of a plurality of splice connections (62) and encapsulant (66). The closure (10) includes first and second cooperating shells (12, 14) defining a bounded region and being telescopically engageable with one another. The closure further includes a living hinge (16) for connecting the first and second shells (12 and 14). The hinge (16) extends continuously across at least one side of each of the shells (12, 14) and is located to allow one of the shells (12) to telescope within the other of the shells (14) when the shells are rotated from an open position to a closed position thus providing an encapsulant displacing force which continuously directs encapsulant (66) within the bounded region away from the living hinge (16) and toward the splice connections (62) contained therein.

Description: CABLE SPLICE CLOSURE BACKGROUND OF THE INVENTION The present invention relates to a cable splice closure and, more particularly, to a single piece clam-shell type closure utilizing a living hinge. Electrical cable made up of a plurality of discrete wires is used in many applications, i.e., telecommunication services. The discrete wires are typically surrounded by a metal shield and an outer protective sheath which protects the discrete wires from moisture and/or other environmental hazards. However, it is often necessary to splice together two sections of electrical cable, for example, to splice long service wires together, to connect service areas and/or to make service connections for individual customers. When splicing two sections of electrical cable together, the metal shield and outer protective sheath must be removed to expose the underlying discrete wires. Thereafter, the individual wires are splice together in conventional fashion. The plurality of splice wires are then typically positioned within a cable splice closure, such closure providing protection from moisture and/or other environmental hazards. To further protect the integrity of the splices located within the closure, the closure is filled with an encapsulant which surrounds and protects the spliced wire. Upon closing of the closure, the encapsulant is squeezed around the spliced wires thereby protecting such wires from moisture. Various prior art closures exist for receipt and storage of spliced wires. A first group of prior art closures are formed with separate top and bottom portions. Two- piece closures are oftentimes less convenient to use in the field, and are less convenient to manufacture. Moreover, a typical two-piece closure is assembled by installing one-piece directly on top of the other part. As will be appreciated by those skilled in the art, this type of assembly may require the application of significantly large forces to the respective halves of the closure, thus making installation more difficult. More to the point, such a design does not allow for flow control of the encapsulant, i.e., the encapsulant will tend to flow along the path of least resistance, such path not necessarily being in the direction where encapsulant is required. Another group of prior art closures are formed as one-piece components. The two halves of the closure are pivotable with respect to one another about a living hinge until such halves contact one another to complete the closure. These prior art designs, although facilitating the use of the closure in the field and manufacturing efficiencies, are typically incapable of directing the flow of encapsulant and of providing a encapsulant-displacing force sufficient to force encapsulant contained within the closure into sealing contact with each and every splice connection contained in the closure. There is therefore a need in the art for a one-piece cable splice closure, such closure utilizing a living hinge whereby installation and manufacture is facilitated. The cable splice closure must be capable of directing the flow of encapsulant and of providing sufficient force to the encapsulant contained in the closure to ensure that such encapsulant is directed to all interior regions of the closure whereby each and every splice contained in the closure is fully encapsulated. SUMMARY OF THE INVENTION The present invention, which addresses the needs of the prior art, relates to a closure for receipt and storage of a plurality of splice connections and encapsulant. The closure includes first and second cooperating shells defining a bounded region and being telescopically engageable with one another. The closure further includes a living hinge for connecting the first and second shells. The hinge extends continuously across at least one side of each of the closures thereby defining an axis about which the shell is rotated with respect to one another and providing an encapsulant-flow barrier along the side. The hinge is located to allow one of the shells to telescope within the other of the shells when the shells are rotated from an open position to a closed position thus providing a encapsulant-displacing force which continuously directs encapsulant contained within said bounded region away from said living hinge while simultaneously retaining the encapsulant within the bounded region. The closure further includes at least two passages extending through the shells and communicating with the bounded region whereby electrical cable may be passed therethrough. Finally, the closure includes securing means for retaining the shells in a closed position. As a result, the present invention provides a one-piece cable splice closure which utilizes a living hinge for ease of installation and manufacture. The cable sphce closure, due to the telescoping interaction of the shells, directs the flow of encapsulant contained therewithin toward the forward end of the closure and into engagement with the sphce connections contained therein. The cable splice closure of the present invention thus channels the encapsulant into all interior regions of the closure whereby each and every splice contained in the closure is fully encapsulated.

DETAILED DESCRIPTION OF THE INVENTION Referring to the drawings, a cable splice closure 10 in accordance with the present invention is shown in Figure 1. Closure 10 includes top shell 12 and bottom shell 14, the halves being rotatable with respect to one another about a living hinge 16. Living hinge 16 is continuous across the width W of the closure. Each of the shell defines an interiorly-located bounded region. Bottom shell 14 of closure 10 includes a pair of cable entrances 18, 20 on one side thereof, and a single cable entrance 22 on the opposing side thereof. The cable entrance allow an electrical cable to extend within the shell and thus communicate with the interiorly-located bounded region. As shown in Figure 1, cable entrances 18 and 20 allow the splicing of cables 24, 26, respectively, via a "butt" splice. Alternatively, one of cable entrances 18 and 20 may be utilized together with the opposing cable entrance 22 to splice two cables via an "in-line" splice. Shell 14 further includes cable support platforms 27 (as best shown in Figure 3 a) which provide additional support and strain relief to the electrical cables proximate the cable entrance. To provide adequate strain relief for the cables entering the closure, closure 10 preferably includes strain relief clips 28, 30. As best seen in Figures la-lb, clips 28 and 30 include a plurality of teeth 32 sized and configured to bite into the cable sheath when the cable is pressed into the cable entrance. As a result, the cable is secured to the closure thereby preventing relative movement with respect thereto. In this regard, closure 10 is preferably formed with receiving cavities 34, 36 for receipt of clips 28, 30, respectively, therein. Top shell 12 of closure 10 includes curtains 38, 40, 42 which initially cover cable relief passages 44, 46, 48. As will be explained further hereinbelow, the curtains initially hinder any encapsulant contained within the top shell from exiting through the cable relief passages. This is particularly relevant in applications where the closure is prefilled with encapsulant whereby the closure will be shipped and stored with such encapsulant. As the top shell 12 is pivoted about living hinge 16 towards bottom shell 14, the curtains contact the cables secured within the cable entrances of bottom shell 14. As shown in Figure 2a, curtains 38, 40 spread apart as such curtains contact the cable passing through the associated cable entrance. When utilizing a butt splice (as shown in Figure 1), curtain 42 located on the other side of the closure serves to close cable entrance 22. Alternatively, the top shell can include cut-away doors which are removed prior to rotation of the shells. Once closed, locking tabs 50 formed on bottom shell 14 engage slots 52 formed on top shell 12 to secure the closure in a closed position (see Figure 2b). This configuration allows an installer to reopen the closure, if necessary. Preferably, the securing means is integrally formed with the shells. Of course, other means of securing the closure in a closed position are contemplated. For example, various locking clips could be utilized, or separate locking members such as bands or pins could be used to secure the closure in its closed position. Alternatively, a ratchet mechanism could be utilized to control closing and reopening of the closure. The present invention preferably utilizes a split bolt grounding shield connector 54. Split bolt connector 54 (as best seen in Figure lc) includes a threaded bolt 56 and a nut 58 and is utilized to securely retain the grounding shields of the respective cables in electrical contact with one another. To facilitate the location of the split bolt connector 54 within the closure, closure 10 preferably includes a raceway 60. The plurality of splice connections 62 are located at the forward end 64 of the closure (i.e., the end of the closure opposite living hinge 16). Finally, closure 10 may includes a support column 63 sized to contact a portion of the top shell when the closure is closed. This support column thus provides structural support to the closure when such closure is subjected to loading forces during its lifetime. As will be recognized by those skilled in the art, cable splice closures utilize an encapsulant to fill the closure after the sphce connections are positioned therein thereby protecting the individual sphces from entry of moisture or other elements into the closure. These encapsulants may include what are commonly referred to as gel encapsulants or paste encapsulants. Referring to Figure 3 a, when a gel encapsulant, i.e., gel encapsulant 66, is utilized, such gel encapsulant is typically provided in both the top and bottom shells of the closure. The closure is typically pre-filled with the gel encapsulant to prevent mixing and messy installations. Referring now to Figure 3b, when utilizing a paste encapsulant, i.e., paste encapsulant 68, such paste is typically provided in only the top shell. The closure may be prefilled with this paste, or such paste may be mixed in the field, and then poured into the top shell 12 of the closure 10. With the use of a paste encapsulant, the bottom shell of the closure typically includes a plurahty of pressure relief holes 70 to facilitate closing of the closure about the spliced cables. This then allows excess encapsulant to extrude out of the closure when such closure is closed. When the closure is prefilled with encapsulant, such shells are preferably sealed with a pull-away foil cover, or other suitable coverings. Alternatively, a mating cover may be telescoped over one or both shells (while the closure is open) to facilitate storage of the prefilled closure. Closure 10 is preferably formed as an integrally molded one-piece component. In one preferred embodiment, the closure is formed from an impact-resistant plastic material such as blends of polyproplyene. One problem typically encountered with prior art closures involves the failure of the encapsulant to completely encapsulate each and every splice and to completely seal the cables within the closure. In this regard, prior art one-piece closures (i.e., those enclosures utilizing a living hinge to join a top and bottom portion of a shell) lack the capability to force encapsulant into every region of the closure. Other prior art closures which utilize separate top and bottom portions are less desirable from a commercial standpoint and, additionally, can be difficult to secure about the spliced cables inasmuch as the top shell of the closure is placed over the bottom shell and pressed directly down thereagainst. In such an arrangement, a sufficiently large force may have to be applied to the closure to close such enclosure. More to the point, it is difficult if not impossible to control the flow of encapsulant within the closure. Thus, upon closing the closure, encapsulant may be forced to travel in a direction away from a splice and/or away from an unfilled interior region of the closure. In contrast, the novel configuration of the closure of the present invention controls the direction of flow of the encapsulant thereby ensuring that each sphce is fully encapsulated with encapsulant and that all interior regions of the closure are filled with encapsulant upon closing of the closure. As will be discussed further hereinbelow, the novel closure of the present invention accomplishes flow control of the encapsulant through the rotational telescoping engagement of the shells of the closure along the entire length thereof. Thus, closure 10 ensures that the encapsulant contained therein is continuously urged forward as the halves of the closure are rotated about living hinge 16. This is accomplished in a one-piece closure, which as mentioned above facilitates field installation and is also desirable from a manufacturing standpoint. Finally, the complete telescoping of the respective shells limits the amount of encapsulant required within the closure by decreasing the resultant interior volume of the closure. Referring now to Figures 4a-4b, as upper shell 12 is rotated clockwise about living hinge 16 from an open position to a closed position, an encapsulant-displacing force is created which force fills the case by urging the encapsulant 68 forward toward the forward end 64 of the closure where the splice connections 62 are located. Inasmuch as the splice coimections are located in the forward end of the closure, the individual wires 71 extend in the direction of the flow of encapsulant, thus not hindering or obstructing such flow. As the top shell of the closure is further rotated about living hinge toward bottom shell 14, the encapsulant continues to be urged towards the forward end of the closure. In this manner, i.e., by initially displacing the encapsulant located in the rearward end of the closure and thereafter pushing the encapsulant forward towards the forward end of the closure, every interior region of the closure is filled with encapsulant. Inasmuch as the individual splices are located at the forward end of the closure, the closing of the box and continuous pushing forward of the encapsulant contained therein ensures that the individual splices are fully encapsulated within the encapsulant when the closure is finally closed. As mentioned above, the closure may include pressure release holes 70 to allow excess encapsulant to extrude therefrom, particularly in applications utilizing a paste encapsulant. It will be recognized that by locating the cable entrances proximate the living hinge, the encapsulant will be "pushed" forward as the closure is moved from an open position to a closed position as the encapsulant contained in the top shell mitially contacts cable 24. Because the two shells are telescoping within one another, the encapsulant in the top shell is displaced as it first contacts cable 24 (i.e., the cable located closer to living binge 16). It will be appreciated that the cables fill a substantial volume of space when positioned in the bottom shell, which causes displacement of the encapsulant when the encapsulant is pressed against such cables. Inasmuch as living hinge is continuous across the rearward end of the closure, an encapsulant flow barrier is created which prevent rearward flow of encapsulant. As the shells are further closed, the encapsulant of the top shell then contact cable 26. Because the rearward end of the closure is already filled, the encapsulant continues to be urged forward toward the splice connection located in the forward end of the closure. The elongate shape of the closure facilitates the channeling of the channeling of the encapsulant forward. Inasmuch as the splice connections are located in the forward end of the closure, sufficient encapsulant will be urged toward such end to fully encapsulate each and every splice position therein. It will be further appreciated that the full telescoping configuration of the closure of the present invention ensures that encapsulant will be urged into all interior regions of the closure, such urging of the encapsulant beginning at the rearward region of the closure (proximate the living hinge) and moving forward as the top shell is moved from the open position to the fully closed position. This displacement is facilitated by the rotational contact of the encapsulant and the interiorly-located components of the splice, which is in direct contrast to the substantially perpendicular contact created in prior art two-piece closures. Because of the proximity of cable relief passage 46 to living hinge 16, a portion thereof, i.e., edge 78 shown in Figure 4a, may be chamfered to facilitate rotation of top shell 12 with respect to bottom shell 14. As shown in Figure 4c, each shell of the closure may be initially filled with encapsulant 66. When utilizing the gel encapsulant of Figure 4c and prefilling each shell, the shell is filled to a lesser extent than when paste encapsulant of Figure 4a is added to a single shell, i.e., top shell 12. This is illustrated by the dashed lines of Figures 4a and 4c which indicate the initial height of the encapsulant. An alternative closure, i.e., closure 10', is shown in Figures 5-6. Closure 10' utihzes a common grounding clip 80 to electrically interconnect the ground shields of the respective cables. Grounding clip 80 is shown in detail in Figures 7a- 7b. In this regard, clip 80 includes wing tabs 82 which flex as necessary to bite into and create an electrical contact with the grounding shield of the cable, i.e., grounding shield 84. Closure 10', together with grounding clip 80, may be used to splice electrical cable in a butt configuration (as shown in Figure 5) or in an in-line configuration (as shown in Figure 6). In each configuration, the individual splices are stowed in the forward end of the closure, with the individual wires extending in the direction of flow of the encapsulant. Closure 10' preferably includes a plurality of posts 86 to facilitate guiding wires to the forward end of the closure. Closure 10' may also include hold down ribs 88 to ensure that the cables remain secure within grounding clip 80 when the closure is in the closed position. Closure 10' is preferably formed with opposing clip receiving slots 90 for receipt of the grounding clip 80 therein. Additionally, clip 80 may include a barb 92 for engaging the sidewalls of slot 90. It will be appreciated that one common grounding clip can be utilized for either a butt splice or an in-line sphce. In another embodiment of the present invention, the closure utihzes a cable strain relief/shield connector 94 (see Figure 8) which preferably uses three flat stamped conductive metal parts 96, 98, 100, each having three distinct cut-outs or slots. The three stamped parts are contained in two mating holders 102, 104. The holders are preferably plastic and configured in a male/female arrangement. In use, these three stamped parts provide the cable shield connection and cable strain relief for the connector. The two holders are designed to contain and control the stamped parts while assembling the splice connections. Connector 94 allows the cable shield connection and strain relief to be assembled prior to inserting the cables into the sphce case. This offers the craftsmen a more flexible work arrangement and minimizes the time spent making contact with the splice encapsulant. The connector, once assembled, provides a "splice block" that can be located in a specific place in the closure. This design provides a means of structurally integrating the strength of the assembled splice connector into the closure, thereby increasing the strength of the closure. Once located in the closure, the splice block will not move with respect to the encapsulant and thus compromise sphce integrity. Connector 94, which provides cable shield connection and cable strain rehef for buried service wire sphces used in the telephone industry, preferably uses an arrangement of two plastic mating holders having a total of three conductive metal stampings. Each of the three conductive metal stamping "blades" are unique having a distinct pattern of three cut-outs or notches in them, sized and shaped for their individual function. One mating shell of the connector, i.e., holder 102, contains one distinct metal stamped part, i.e., part 96 (see Figures 9a-9c). The opposite mating shell, holder 104, contains two other distinct metal stamped parts, i.e., metal parts 98, 100 (see Figures lla-llc). The single center blade connector shell , i.e., holder 102, is used first during sphce assembly. The single stamped conductive metal part 96 it contains preferably has three cut-outs of equal size and configuration to grip onto the exposed cable shield of up to three different cables. This provides "grounding" for the cable shield. Each individual cable shield is pushed down into the notched cut-outs of the connector "blade". The cable jackets are located flush to the connector "blade". (See Figure 10). The holder is shaped to mate with and slide within dual blade holder, i.e., holder 104 (see Figures 8 and 12). The dual blade holder is used second during the splice assembly. It contains conductive metal stampings 98 and 100, each having a distinct pattern of three cutouts or notches in them, sized and shaped for their individual function. One stamping, i.e., stamping 98, is designed to grip and secure a central cable shield and cable jackets on either side. The second of the pair of stampings, i.e., stamping 100, is designed to grip and secure one central cable jacket and two cable shields on either side. These cut-outs provide both shield "grounding" and strain relief to the splice block. Identification notches 110 are provided on the stamped parts to aid in manufacturing. These identification notches match projections on the holder. Connector half 106 (which includes holder 104 and stamping 98, 100) is preferably shaped to mate with and receive connector half 108 (which includes holder 102 and stamping 96) within channel 112. Once assembled, connector 94 provides three (3) positive gripping contact points on each of the up to three cables used in the sphce connection. Each cable is gripped once on the cable jacket and twice on the cable shield (see Figure 12). In use, connector 94 allows for the construction of three types of service wire splices: (1) inline; (2) three-way; and (3) butt splice (see Figure 14) within one common assembly. It will be appreciated that the present invention has been described herein with reference to certain preferred or exemplary embodiments. The preferred or exemplary embodiments described herein may be modified, changed, added to or deviated from without departing from the intent, spirit and scope of the present invention, and it is intended that all such additions, modifications, amendments and/or deviations be included within the scope of the fo Rowings claims.
