Description

DETAILED DESCRIPTION OF THE INVENTION With respect to its manufacture and use, and more particularly, an article made of a flexible polymeric material having a body and at least two tubes extending from an opening in the body, and the use of such article in cable breakouts. , relates to methods of manufacturing such articles and methods of forming cable breakouts.

Such articles are preferably made at least partially of an electrically insulating polymeric material and are at least partially heat recoverable.

A heat recoverable article is an article that can substantially change its dimensional configuration when subjected to heat treatment. Typically, these items are
When heated, it recovers to its original shape before deformation, but in this specification, the term "thermal recovery" includes those that have not been deformed beforehand and take on a new form when heated.

Such articles, in their most common form, are described, for example, in U.S. Pat.
0 8 6.

No. 242 and No. 3,957,962, it comprises a heat-shrinkable sleeve made of a polymeric material exhibiting elastic or plastic memory properties. For example, as shown in U.S. Pat. No. 2,027,962, continuous processes in which extruded tubes are expanded while hot to a dimensionally thermally unstable state temporarily lose their original dimensionally thermally stable shape. It can be of any shape, but,
The otherwise preformed dimensionally heat stable article is
In a separate step, it is transformed into a dimensionally thermally unstable shape.

One method of making heat recoverable articles is to form the polymeric material into the desired heat-stable shape, and then crosslink the polymeric material to form the article above its crystalline melting point or, if amorphous, its softening point, depending on the type of polymer. It consists of heating to a temperature, deforming the article, and cooling while in the deformed state to maintain the deformed state of the article.

During use, the deformed state of the article is thermally unstable, so heating will cause the article to return to its original thermally stable shape.

In other recoverable articles, as described, for example, in British Patent No. 1,440,524, an elastic member, such as an outer tubular member, is held in tension by a second member, such as an inner tubular member. The second member is then weakened by the heat treatment, allowing the elastic member to recover.

Cable breakouts using heat-recoverable wrap-around sleeves are known (e.g. British Patent No. 2,
019,120). Another known form of cable breakout is the so-called sleeve 31A canister, which is used to radially distribute each pair of telephone wires towards a plurality of handsets at predetermined locations along the main cable. . In this arrangement, the main cable enters or exits the domed canister through a hole in the bottom of the canister, and the paired wires to be branched are brought out through another hole in the bottom of the canister.

The pores are filled with a suitable thermoplastic compound, but the moisture barrier effect is somewhat unreliable. The canister itself also has a removable top half connected to the bottom part by a mechanical fastening ring.

The present invention seeks to provide an article or assembly that can be used for breakouts of many other shapes, and that can be used for breakouts of many other shapes, in order to significantly improve the reliability of the above-mentioned type 31A breakouts. be.

That is, in accordance with one aspect of the invention, the body has a body and at least two tubes extending from an opening in the body, the length and flexibility of the tubes being such that the length and flexibility of the tubes are such that at least one of the tubes is An integral unit, characterized in that it is capable of being bent away from other tubes to such an extent that operations performed on the end can be performed substantially independently of the other tubes. An article formed from a polymeric material is provided.

According to another aspect of the invention, the invention comprises a body and at least two tubes extending from an opening in the body, at least a portion of the at least one tube being formed from a polymeric material to allow recovery to an uninflated state. The length and flexibility of the tubes may be such that at least one tube is temporarily in a stable inflated state and the recovery of the inflated portion of that tube is substantially independent of the other tubes. An article is provided which is characterized in that it can be bent away from other tubes to an extent that allows it to be bent.

While a planar body with a tube extending through the aperture may be useful in some applications, the body is preferably in the form of a hollow shell capable of accommodating a particular cable, and the tube is an outlet from the body. functions as In either case, the tubes, when unbent, are preferably substantially side by side, preferably substantially parallel, and in fact each may be bent away from the other as described above. There are usually at least two tubes of such length that the This may affect the appearance or ease of use, particularly if the body is tubular and the tubes extend from one end of the body and are preferably aligned with the body and arranged symmetrically around the tube axis of the body. It is advantageous in this respect.

At least a portion of each outlet is preferably molded from a polymeric material and is in an expanded state, the length and flexibility of the outlet being such that any one of the outlets can bend from the other to the extent described above. It has been done to a certain extent. The article is preferably molded as a fourteen unit, although separate body and outlet section assemblies may be convenient in some applications.

The usual use of relatively long and flexible exit tubes
This allows the tubular legs of the electrically insulating element, even with normal wall thickness, to be easily bent away from each other so that work can be done with one leg without substantially affecting the other legs. This is advantageous because it is long and flexible enough to

This is particularly useful in the case of heat recoverable articles since one leg can be recovered around a cable passing therethrough while the other leg is left unrecovered for later use. Those skilled in the art have no difficulty in determining what leg length and flexibility is sufficient for a particular application.

Advantageously, the outlet section is corrugated at least at the end near the body and the outlet is selected away from other outlet sections for recovery during use! It's easy to bend a minute.

The corrugation is preferably designed such that the corrugated section can be bent at least 90' without occluding the exit inner passageway.

Recoverable articles of this type preferably have an outlet having a substantially uniform average inner diameter over all or most of the outlet length, preferably including the full-gated portion.

In the uniform part of the outlet, whether in the expanded state or not,
The ratio of length to average inner diameter is at least 1o:1, preferably at least 20:L and especially greater than 30:1.

Such a ratio is not readily achievable with standard manufacturing techniques for conventional heat recoverable cable breakouts for more useful dimensions (eg, for recovery around a pair of telephone dropout cables). The reason for this is that there are limitations resulting from the inevitable increase in flexibility with increasing length of the support bins normally used as inner supports for forming tubular articles, and the actual lengths obtained are The maximum unexpanded inner diameter ratio was 2°:1. An expansion ratio of at least 2:1 is required, and molding techniques therefore result in relatively modest products with expansion ratios of 2:1 or less. Therefore, blow molding is the preferred method for manufacturing the articles of the present invention.

A preferred shape of the article of the invention has a substantially tubular body having a circular or other shaped cross-section and an outlet portion extending from the end of the body substantially parallel to the tube axis of the body.

Other arrangements are possible, with the outlet section attached to a longitudinally split body so that it is wrapped around the main cable in which the breakout is formed, with a closure suitable for such wraparound devices. Jar systems are described, for example, in US Pat. No. 3,455,336.

According to another aspect of the invention, there is provided a housing capable of accommodating in use a portion of a cable that is split into one or more portions, a body attached to the housing and at least two cables extending from an opening in the body. an article comprising tubes, the length and flexibility of the tubes being such that at least one tube can be used substantially independently of the other tubes for operations to be performed on at least one end of the tube. An enclosure is provided which is adapted to be able to bend away from other tubes to an extent that allows the tube to be bent away from other tubes.

The article is preferably as described above, the body comprising a housing of known type, for example US Pat. No. 3.4.
55.336 or a housing similar to the sleeve 31A canister described above. In the latter case, it may be convenient for attachment to modify the canister to have a short tubular protrusion from the outlet hole, which facilitates connection of the outlet article, preferably by recovery onto the protrusion of the recoverable body. Ru.

In some circumstances, attachment by adhesive or other means with or without recovery may also be convenient.

The housing is preferably dimensionally heat stable (ie, non-heat shrinkable) and preferably has openings in its bottom or walls to allow entry and exit of the cable in which the breakout is to be made.

This entry-exit port is conveniently located at the bottom of the cylindrical housing between the two exit holes present, as in the four-legged breakout article described above.

The legs of the breakout article may enclose the pre-installed wire, and the distal end of the leg (other parts of the leg ) is inflated, after which the distal end of the leg is restored.

According to the invention, there is further provided a method of forming a cable breakout in which a cable portion is drawn through a tube of the above-mentioned article or a connection is formed at the free end of a cable extending through such a tube. wherein one tube is bent by bending one tube or the other tubes to an extent that allows operations to be performed on at least one end of one tube to be performed substantially independently of the other tubes. Separate the tubes from other tubes and then work on a section of the tube that is independent of the other tubes to separate the corresponding cable section and/or
Alternatively, a method is provided, characterized in that the tube is sealed around the connection.

In general, it is advantageous to bend one recoverable outlet section to be recovered away from the other outlet sections so that the other outlet sections do not concomitantly recover and recover independently.

A preferred method for manufacturing breakout articles of the invention is to provide a parison of polymeric material and blow-mold the parison in a suitable mold to initially have the tubes separated from each other or to later The process involves obtaining the desired article having separate but initially integral tubes and then crosslinking the polymeric material. Preferably, the method includes expanding at least a portion of the article to a temporarily stable expanded state that is recoverable to an unexpanded state. The steps of this method can be performed in any order.

On the other hand, the article can be manufactured by fusing together two overlapping sheets of polymeric material or a single sheet of polymeric material folded in half. Preferably, crosslinking can be carried out by irradiation before the expansion step, which can then be carried out by known methods at a temperature above the melting point of the polymer. However, cold expansion before crosslinking (preferably before fusion) can optionally also be employed.

Cold expansion means expansion at a temperature below the crystalline melting point or softening point of the polymeric material used.

Breakout articles of the invention having substantially aligned outlet tubes in a tubular body can advantageously be made by flow forming processes, while three or more outlet tubes are substantially in one plane. Side-by-side articles can also be made by fusing methods that provide a series of breakout articles that can be separated by cutting.

For articles with more than two outlet tubes, the tubes are formed in a non-planar and substantially symmetrical pattern, such as triangular (for three) or square (for four).
preferably arranged around the axis of the tubular body.

This results in a better appearance than the substantially planar arrangement described above. The resulting article is then heated, for example, to a temperature above the crystalline melting point of the polymeric material, stretched on suitable mechanical means inserted into the article, cooled in the stretched state to below the crystalline melting point of the polymeric material, and then It can be inflated by removing it from the means.

Additionally, the recoverable articles of the present invention can be made by assembling separate parts.

In accordance with the present invention, there is provided a cable breakout manufacturing kit comprising a heat recoverable wraparound sleeve and the breakout article described above.

further comprising a dimensionally substantially stable housing capable of accommodating a portion of the cable and having at least one exit hole through which a conductor drawn from the cable passes, and at least one article as described above; A cable breakout manufacturing kit is provided.

Some aspects of the invention will now be described with reference to the accompanying drawings.

FIG. 1 illustrates one embodiment of the invention in which a breakout article having an outlet portion substantially aligned with the major axis of the body is coupled to a nousing. In this case, the nowing is a heat-recoverable wrap-around sleeve that houses the main cable.

To simplify the drawings, the four outlet sections 51-54 are shown on the left side of the drawings as the shape that would be used in the absence of a preloaded drop-in line, and on the right side of the drawings as 51A, 5
2A, 53A, and 54A are shown as the configurations used when preload drop lines are present. Although other arrangements of the outlet sections may be used if desired, it is usually convenient and aesthetically pleasing to arrange the outlet sections substantially parallel to the major axis of the body. According to the invention, the flexibility of the long outlet section is sufficient to accommodate the withdrawal of the drop line in different directions, as well as the flexibility of the other outlet section adjacent to the one outlet section to be restored. This is sufficient to allow specific outlet sections to be heated and recovered independently without the use of cumbersome heat shields to prevent severe recovery.

Outlet portions 51 and 52 are depicted with closed ends. The closed end can be formed during manufacture of the breakout article, or it can be formed by snapping it closed after initial molding if the resulting seal is strong enough for the intended use of the article. Exit section 53 is shown with the closed end cut away to accommodate the breakout section of the main cable. Outlet section 54 is shown restored onto the breakout cable section and carries a pair of drop-in wires. A hot-melt soil adhesive 57 protrudes from the end of the recovered outlet portion 54.

On the right side of the drawing, the outlet section 51A is depicted after connecting the preloaded drop wire contained therein to the extraction cable and applying hot melt adhesive 57 for sealing as before. Accompanying. The outlet section 52A is similarly depicted with the preloaded dropout line tangent to the pullout cable 59 and has the small heat recoverable sleeve 58 necessary to seal between the outlet section and the pullout line. Outlet portion 53A is depicted ready for use, with a closed end that wraps around the preloaded dropwire to protect it from contamination prior to use. Exit part 54
A has an enlarged distal end 54B adapted to enclose the connection formed in use between the preloaded drop-in wire and the extraction cable, with recovery of the distal end 54B enclosing and sealing the connection. Ru.

Bodies 55 and 5 of breakout articles 50 and 51
6 are heat-recoverable sleeves 6 by clips 61, respectively.
It is housed within the opposite end of 0.

The clip 61 attaches to the sleeve 60 around the main cable 62.
and breakout article 50.51 are suitably sealed at each end. Heat-recoverable wraparound sleeves with sealing clips of this type are generally known from British Patent No. 2,019
, No. 120.

FIG. 2 shows an improvement of the known "81eeve 31A" according to the invention. In this arrangement, the housing 70, which corresponds to the lower half of the 31A enclosure, has holes 71.7
2 and 73 (see plan view in FIG. 3), hole 71 allows insertion and exit of the main cable, and holes 72 and 73 allow exit of the breakout portion of the cable. The housing can be molded from a water resistant polymeric material by molding or other molding methods.

In this refinement, holes 72 and 73 are provided with extensions 75 and 76 (FIG. 2) around which breakout articles 77 and 7B of the invention can be contracted. Each of the articles has four exit sections and houses a total of eight sets of drop-in wires distributed to each handset. The heat recoverable sleeve 79 is restored onto the extension 74 (FIG. 3) of the hole 71 with the sealing means 80. Said means 80 provide a seal between the insertion and exit portions of the main cable 81, as detailed below. Corrugations 82 are provided to increase the flexibility of the sleeve during and after installation.

The sealing means 80 comprises opposed male and female mating portions 101, 102 formed on opposite sides of the tubular sleeve 79, as shown schematically in cross-section in FIG. preferable. After fitting these parts together, retaining means 103 are preferably applied. In order to strengthen the resulting seal, the male part 102 is preferably provided with retaining means 1
04 is supplied.

This Ω-shaped or papilla-shaped sealing means is described in British Patent Application No. 8
No. 119243.

Again, the hot melt adhesive 83 provides a good seal between the breakout article and the extension.

Outlet sections 91.92.93 and 94 correspond substantially to outlet sections 51.52.53 and 54 of FIG. 1, and outlet sections 91A, 92A, 93A and 94A substantially correspond to outlet section 51A of FIG. , 52A, 53A and 54A. Although the outlet section 2 is provided with a preferred corrugation 95, such corrugations may also be provided on all outlet legs.

The housing closure dome 100 is attached to the lower half of the housing 70 by a fastening ring of the enclosure 31A and is attached to the housing 70 by a resilient sleeve 101.
It is sealed in the lower half of the. The sleeve may preferably be a heat-recoverable sleeve coated with a heat-activated adhesive on the inner surface, but may also be a cold-shrink tubular closure.
For example, it is also preferred to use an elastic layer 102 held in an expanded state by a substantially rigidity retaining layer 103 as shown in the inset. Roger thus disclosed U.S. Pat. No. 4,035,534 and U.S. Pat.
and No. 4,135,553, and from the above-mentioned state, a liquid that destroys the bond of the adhesive layer between the elastic layer 102 and the retaining layer 103 or softens or dissolves the retaining layer itself. The liquid is released to restore the area around the joint between the upper housing 100 and the lower housing 70. Preferably, a pressure sensitive adhesive layer 104 is provided on the inner surface of the elastic layer to provide a good seal around the joint between the upper and lower housings. This joint can be designed as shown in the inset to maximize leakage path prevention, thereby promoting effective sealing.

An arrangement in which eight outlet holes (other numbers are possible if desired) are provided in a dimensionally stable housing 70, each having a single outlet section or tube of the required length and flexibility. is also possible, but somewhat undesirable. In such an arrangement, the housing itself, which is not necessarily made of polymeric material, can be considered the hollow body of the breakout article of the invention with a long flexible outlet.

If a heat-shrinkable article is used, a coating of adhesive, preferably a hot-melt adhesive, can optionally be provided on some or all of the interior surfaces of the breakout article of the invention, thereby providing an exit section. This facilitates sealing when the cable is restored to the cable breakout area. Suitable adhesives are described, for example, in US Pat. No. 4,181,775.

The outlet portion or legs of the breakout article are not limited to any particular arrangement. However, certain leg lengths and flexibility allowing individual recovery without concomitant recovery of other legs may be advantageous aesthetically and industrially, e.g. four corners aligned in a tubular body. 4 in
Providing a book leg-like arrangement is one of the advantages of the present invention. This arrangement is particularly preferred because it is easily adapted to the eight-lead distribution system for telephones shown in FIG. 2, and other arrangements such as those shown in FIG. 1 are also readily adaptable.

In use, breakouts can be made using the articles shown in FIGS. 3 and 4.

Next, examples will be shown to explain the present invention.

Example: Make a loop in the main cable at the connection point. The sheath on top of the loop is removed over a total of 20 cIrL. Approximately 30crr of cable sheathing on either side of the exposed cable portion
The L is cleaned, sanded, flame brushed and adhesive coated aluminum foil is applied to prevent scorching of the exterior. Remove the cap from the main housing and release the sealing means leaving the main cable tube 79 undivided. Protect the greased wire with a polyethylene bag and thread the loop through the main cable tube 79 to access a sufficient length of exposed wire on the bottom of the connection nozzle.

Bend the main cable away from the other exit tubes,
Wrap the other outlet tube with heat reflective foil. The branch seal 80 is closed under pressure and a retaining groove is installed to seal between the inlet and outlet portions of the main cable. Heat the main cable tube from about 3 CWL away from the corrugation to the tip of the tube. Allow the attachment to cool for approximately 3 minutes and inspect to see if the adhesive has melted properly to form a seal. Cut off the end (approximately 05 to 1 cIrL from the tip) so that you can pull out as many small cables as there are legs from the exposed main cable.

Degrease, clean, make the drop wire to the required length, apply adhesive to the aluminum foil, and degrease the foil before attaching the drop wire to the outlet of the appliance.

Connections between main cables and service lines may be made at this stage and no further heat shrinkage should occur until all connections are complete.

Each drop-in wire carrying an outlet is bent away from the other drop-in wires, and the ends are contracted by approximately 5 crIL to check that sufficient adhesive has flowed. Repeat this for all lead-in lines.

Place the housing cap and wrap one layer of adhesive tape around the joint between the cap and the bottom of the housing.

Use a Roger sleeve if necessary to ensure a seal at the joint.
