為に接続部分に容易に接近できる組立体に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention provides protective insulation for connections between conduits, such as multicore cables, and provides easy access to the connections for repair, modification, or inspection. Relating to accessible assemblies.

くの問題が生じる。[Prior Art] It is often necessary to insulate and protect connecting portions between conduits, typically electrical cables such as multicore cables. Many problems arise when attempting to connect cables, such as telephone cables or power cables, in the field.

し得るようになっている。For example, British Patent No. 1,155,470 proposes the use of sleeves or tubes made of heat-shrinkable material, which may have longitudinal cuts, to protect and insulate the connections of electrical cables. ing. The sleeve has a suitable initial diameter under stress so that it can be easily moved into position, and when heated it contracts to fit tightly over the connection. It is now possible to do so.

い。Since the cable must be pressure and water resistant, it is necessary to coat the inner wall of the heat-shrinkable sleeve with a sealing compound, such as mastic or hot-melt adhesive.Heating the sleeve seals it. The compound melts and forms a water- and pressure-tight seal between the sleeve and the cable.The disadvantage of this type of protective sleeve for enclosing the connection is that it may require repair or modification. This cannot be opened easily when attempting to do so, and the entire connection must be renewed if, for example, an additional cable is to be inserted.

互に連結されている。British Patent No. 1,248,908 discloses a method for connecting electrical cables using a bridge sleeve of non-heat-shrinkable material and an end sleeve of heat-shrinkable material, said sleeves being secured by screws, for example. interconnected.

くする必要がある。Such an assembly unit is positioned such that the bridge sleeve lies over the connecting portions of the cables and each cable is surrounded by one of the end sleeves. The connections are then sealed by heating the end sleeves so that they contract over and grip each cable. Such devices require relatively tight manufacturing tolerances to allow easy engagement of the male and female threads on the bridge sleeve and the end sleeve.

で収縮するようにされる。The central section of the heat-shrinkable sleeve shrinks over the split tube.
The split tubes are not sealed or even if they are sealed, they are kept to a minimum. This is done, for example, by suitably selecting the sealing material or the surface properties of the split tubes. It should be noted that only the end sections of the heat-shrinkable sleeve are covered with a sealing compound, such as mastic or hot melt adhesive, leaving the central section of a length substantially equal to the length of the split tube uncoated (leaving no residue or shrinkage). When this occurs, only the covered end of the sleeve is allowed to shrink onto and bond to the conduit, while the uncoated central section is allowed to shrink without bonding over the split tube.

になっている。The heat-shrinkable sleeve can be of a circumferential type with longitudinal cuts, if desired. The sleeve is then provided with sealing means along the cut, such that a water- and pressure-tight connection is obtained after the shrinkage has taken place.

うな閉鎖部材は特に好適である。The joint covering assembly according to the present invention can be easily opened by cutting the central portion of the heat shrinkable sleeve to allow repair or modification of the joint. The split tube can then be easily removed if it is not sealed against the shrinkable sleeve. If a seal is provided, the seal strength can be reduced if desired by heating the assembly to the softening point of the sealing material. After repair or modification, the split tube is put back into place and the connection is resealed, for example by a surrounding heat-shrinkable sleeve with a notch. The inner wall of the sleeve is coated with a sealing material and is adapted to seal the notch and form a water-tight and pressure-tight connection. A closure member such as that described in GB 1°155.470 is particularly suitable.

ブルを挿入しかつ全体に密封テープを巻付ける。When connecting cables, it may be necessary to add a new cable to the connection section in some cases. This can be easily accomplished by providing the heat-shrinkable sleeve with notches along its entire length so that the entire sleeve can be removed. The sealed end compartment is
This can be removed by heating to soften the sealing compound. The split tube is then removed, a new cable is inserted and the whole is wrapped with sealing tape.

。In an assembly according to the invention, said split tube is provided with a plurality of relatively flexible large projections spaced about said tube at least at one end of the conduit (preferably at each end). the heat-shrinkable sleeve is formed to have a length greater than the total length of the split tube and the protrusion.

化する区画が突起によって補強されるようになる。In this example, when heat is applied to the sleeve of heat-shrinkable material, the central section surrounding the split tube contracts slightly to firmly grip the tube. The reason for this is that the split pipes have relatively high rigidity. The section of the sleeve surrounding the protrusion tends to contract progressively from the end of the split tube towards the end of the protrusion. This is because the protrusion becomes progressively more deformable toward its distal end, and near the end the sleeve becomes stiffer (contracts) relative to the conduit. Providing such a protrusion This allows the sleeve to smoothly taper in diameter from a large diameter section surrounding the split tube to a small diameter section surrounding the conduit, thereby reducing stress on the sleeve material and reducing the diameter. The changing compartments of the area become reinforced by protrusions.
熱収縮性スリーブの内壁の端部区画だけを密封剤によっ
て密封すべき場合には、スリーブの端から突起の長さに
沿ったほぼ中央の点に至るまでの区画を適当に被覆する

が施されず、収縮が行なわれた場合にはスリーブの被覆
された端部が突起および導管（ケーブル）の上に収縮し
、かつ被覆の施されない中央区画は割り管の上に収縮す
るようになる。If only the end section of the inner wall of the heat shrinkable sleeve is to be sealed with a sealant, the section from the end of the sleeve to a point approximately midway along the length of the protrusion is suitably covered. The central section, which is slightly longer than the split tube, is therefore uncoated and, if a contraction is carried out, the coated end of the sleeve is shrunk over the protrusion and the conduit (cable) and remains uncoated. The central compartment becomes constricted onto the split tube.

れらを損傷する。The protrusions can be suitably made of aluminum, which has high strength, light weight, and flexibility, but may also be made of cardboard or the like. The protrusion should be tapered towards the end so that its deformability increases progressively towards its free end. In addition, the taper prevents the protrusions from overlapping at the free end.
The surface of the shrunken sleeve becomes smoother. Without tapering, the aluminum protrusions overlap and the sharp corners and edges of the protrusions can dig into and damage the wire sheathing and sleeve.

許請求の範囲第１項記載の組立体。[Claims] 1. In an assembly for protecting and insulating a connection between conduits and allowing re-access to the connection, a relatively a rigid split tube and a plurality of relatively flexible protrusions spaced around at least one end of the split tube and projecting axially beyond the end, the split tube and the protrusions; is surrounded by a cylindrical heat-shrinkable sleeve that is longer than the combined length of the split pipe and the protrusion, and when the heat-shrinkable sleeve is shrunk onto the connecting portion, the end region of the sleeve that is shrunk onto the conduit is the conduit. A sealing material is applied to at least a portion of an inner wall of the sleeve so as to seal the sleeve, and the protrusion continuously changes the diameter of the contracted sleeve between the split tube and the conduit. 2. The assembly according to claim 1, wherein the protrusion is tapered toward the tip.
