The invention relates to a device for enclosing parts of the elongated objects, for example, electrical wire conductors, and to a material for sealing, preferably gel that protects these items from violations.Known selectabase shell for many purposes, n is which have significant advantages, especially in some of the devices described below.Device for enclosing parts of the electric wire material for sealing containing at least two forming the casing element, joined together for the protection of the mentioned parts of the wires, at least one of which has a bottom portion and a vertical wall, with the formation of capacity (mainly non-groove) to hold the solidified therein a liquid sealing material to at least one of the vertical walls mounted for movement from interaction with one or more movable parts of another forming a casing element when the connection.The advantage of this invention is that a relatively thin flat layer of material for the seal can be formed in forming the casing elements, even when this material has a low initial fluidity and long solidification time (for example, polysiloxane gels described in the aforementioned EP-A-0108518) and can then be used to seal all around the elongated objects, stretched from the device, mostly parallel to the surface of the seal that security is someone moving wall, forced to hold material for sealing prior to its solidification, would prevent the passage of objects when closing the sealing device relative to them. The advantage of floating walls is also a great strength in the production and use of a sealing membrane than the strength achieved fragile walls thin enough to collapse from the lateral pressure of the objects on top of the wall when the closure device. Such movement of the wall may in some cases allow material to seal leaking around the protected objects or in other desired directions, but it is preferable that the material for sealing was basically not fluid, particularly preferably in the gel state before closing the device, which moves the wall.Information related to zatverdevaya liquid material for sealing, include material, initially in a liquid molten state, followed by solidification in the above-mentioned capacity due to cooling, for example grease, wax or thermoplastic gels, especially the oil-filled styrene-hydrogenated alkylene-styrene triblock copolymer gels with added Polyphenylene through a chemical reaction, preferably polysiloxane gereformeerde materials may be preferred, especially for use at high temperatures, for example, when the protection of the wire conductors in the heated parts automotive wire transactions and nodes.Preferably, forming the casing elements are located such that when you add them together during use was shielded least part of the objects, and these parts, at least partially, would be in the tank and out of through the space previously occupied by the movable wall. It is easy to see that elongated objects, such as wire, compressed side in the layer of material for sealing, preferably gel, closing in around them forming the casing elements. Floating wall in the highest degree useful, as it allows you to automatically harden and fill zatverdevaya sealing material even with initially very low turnover, such as the above-mentioned polysiloxane gels. At the same time, remaining stationary, the subject pressed cured gel in a flat form to save valuable space, for example, when you use where space is TBE cases mentioned tank, at least two vertical walls preferably four vertical walls, is preferably rectangular in shape, floating wall represents one of the vertical walls. The capacity can be, for example, formed of a single curved wall, the ends of which are connected with the ends of a single roaming (essentially straight) wall, although for many purposes it will be preferable to have four vertical walls in a rectangular performing. Essentially straight walls can be preferred in all cases. The ends of the respective walls will be determined by various connection points, although it is not necessary in the acute, or straight angles, and the cross-sectional shape of the walls throughout their length need not be constant and correct.In some assemblies mentioned floating part(s) formed(s) to interact with at least one (preferably two) end(s) area(s) floating wall to provide moving during use. In such cases, it is preferable that the end(s) area(s) floating wall was(s) increase(s) for the formation of the Cam or lever, to which the roaming part would rely for obespecheniiu element, bearing this wall, and when you use the move entails turning on the floating hinge wall toward the bottom. The hinge is preferably a valid hinge, formed in the casting forming the casing element, and in variants of the invention are designed on the assumption that the device will rarely be closed or to be closed only once. Acceptable hinge can be obtained even with unusually high-quality glass or other solid filler contained (for example, 40% by weight) in the casing material. Preferably, the execution is such that when using basically the entire length of the floating wall move when closing the casing forming elements. Another location roaming the walls of the device and other movement mechanisms, however, are not excluded.In especially preferred embodiments of the present invention fragile jumpers connect each end of the floating wall with the adjacent wall. Being fragile, jumpers destroyed during the movement of the wall during use. Should be taken into account that such fragile bridges can be made very short, connecting only the male is Cai and subsequent use, than long fragile wall, which can be subject to breakage or fracture during production. Durable floating wall is relatively short, fragile bridges will be suitable for high speed production, for example, by injection casting, high volume production, for example, conductors for the car. Preferably jumper is made with grooves to increase wear.The device according to the present invention include devices with the said tank having only one roaming the wall, so when you use extra long items out of the device essentially in one direction; and devices with a tank having at least two floating wall so that the elongated objects using can leave the device in at least two directions inclined one to another, preferably at an angle of at least 60omore preferably at an angle of at least 90oand particularly preferably at an angle of 180o.In many cases it would be preferable that the other forming the cover element forms a second tank with at least one roaming the changes in any combination to the second container and roaming(output) wall(s). Therefore, while forming the first capacitance element with the second forming the capacitance element forming the cover, can be used for some purposes, it is generally preferable for forming two casing elements to be similar to each other, perhaps in some respects to be mirror-reflected, and, at the same time, providing variation to be conveniently fitted and United together. Preferably forming the casing elements are cast as a single unit from a plastic material, preferably polypropylene. Suitable known methods of casting and equipment can be easily selected by a specialist in this technology. Polypropylene containing 40% by weight glass fiber filler is preferred casing material, although other cast polymers can be selected depending on the production conditions and/or end use.Preferably forming the casing elements pivotally connected together to close during use. The hinge is preferably formed in the casting process both elements of the casing. Forming the cover elements can be connected together in any known way, after clamping, preferably joint Sam way to be firmly established around parts built flat elongated objects, preferably electrical wires. The diameter of the largest object preferably not exceed more than 4 times, preferably not more than 2 times the diameter of the smallest closed subject. The device of the present invention, especially when using binders and corresponding gel sealing material, can provide all kinds of different sizes and quantities of items such as subject the fence wire.The invention includes a device with the above-mentioned sealing material in the vessel(s). The sealing material is preferably a gel, more preferably, cross-linked polysiloxane gel, as mentioned before. Reference EP-A-0108518 is given as a reference. Suitable polysiloxane gels or other chemically cross-linked gels, such as polyurethanes or thermoplastic gels, preferably oil-filled tribromaniline gels, as essentially known, can be selected according to convenience and end usage requirements. Polysiloxane gels with their tendency to provide the highest temarii for cross-linked reaction of their polymerization in the hardened condition and are suitable for obtaining the advantages of holding capacity and repositionable wall according to the present invention. The device according to the invention is particularly well combined with automated filling sealing material containers for injection casting. All devices provide high speed production, necessary for high-volume automotive and other markets, as mentioned above. The invention includes devices that are connected together using relatively elongated objects, preferably electrical wires, although the invention can also be used with optical fibers or other elongated objects.Specific variants of the present invention will now be described with reference to the accompanying drawings, where:
