Description

Technical field

The present invention relates to a sealant, bushing or adapter for cables, wires or pipes. In particular, the invention relates to parts of a sealant or adapter having peelable layers to fit the dimensions of an inserted cable or pipe.

State of the art

Cable adapters and the like are known from the prior art having a frame in which modules for inserting cables, wires or pipes are located. The modules are made of an elastic material, such as rubber or plastic, which is why they are compressible. In the frame, the modules are usually located in one or more rows together with a compression device. The compression device is located between the frame and the modules in such a way that when it expands, the compressible modules are compressed around cables, wires or pipes.

For simplicity, the term “cable” is mainly used in the description, but it should be considered in a broader sense, and for a specialist it is obvious that this term, as a rule, also means pipes or wires. The same applies to the term “seal”, which also includes bushings and adapters and should be considered in a broader sense.

Sealers, cable adapters, pipe adapters, etc. other type of devices are generally cylindrical in shape and are designed to be placed in a sleeve or hole in the wall. For proper functioning, the seal must enter without a gap into the sleeve or hole in the wall, designed for this, and must be able to fit the actual installation dimensions. Installation dimensions are determined by the inner diameter of the sleeve or hole. The sealant has a cylindrical compressible housing, which can be axially compressed between connecting devices located at opposite ends of the compressible housing. The compression of the cylindrical body in the axial direction causes its expansion in the radial direction inward and outward. In addition, the inserted pipes or cables may have different external diameters, so the module must be adapted to fit the cables or pipes. having various external diameters.

Sealers of both of the above types are used to seal bushings in various equipment, for example, cabinets, technical booths, distribution boxes and installations. They are used in various industrial equipment, for example, automotive, telecommunications, equipment for the production and distribution of electricity, as well as in marine and coastal equipment. Seals or transitional devices can be used for sealing in order to prevent the penetration of liquid, gas, fire, rodents, termites, dust, moisture, etc., while they can accept electrical cables used in communications, computer or other cables or wires, pipes for various gases or liquids, such as water, compressed air, hydraulic fluid and household gas, and wires to hold the load.

Parts receiving a single cable, etc., of any of the two types described above, often contain a stack of peelable layers or sheets on their inner part. The layers or sheets are peeled off one after another until the inner diameter of this part is adjusted to the outer diameter of the cable received by the indicated part. The sheets are connected to each other firmly enough to stay together, and at the same time loosely enough so that they can be peeled off from the foot one after another or several sheets at once. In some embodiments, peelable layers or sheets are also located on the outside to adapt the outer dimensions, such as a circular seal, to the specific dimensions of the hole or sleeve.

Those skilled in the art will appreciate that the exact appearance and shape of various parts, such as layers, can be changed without departing from the scope of the present invention. For example, the stack of layers may have a different cross-sectional shape other than circular.

SUMMARY OF THE INVENTION

When installing cables or pipes, a suitable number of layers must be removed. If all layers are identical, it is often difficult to determine the exact number of layers to be removed. Depending on the compaction requirements, it may be necessary to know that the correct number of layers has been removed. Separate labeling of the layers makes it easier for the worker to remove the correct number of layers, and also provides a simple check after installation that the correct number of layers has been removed.

The location of the protrusions on at least one side of the layers, facilitates the process of their removal. Instead of using protrusions, the marking can be located directly on separate layers. Marking for protrusions and / or layers can be performed, for example, in the form of signs, letters, or various colors. Thus, installation can be done faster and with fewer errors. Also, the risk of removing multiple layers can be prevented when only one layer is removed. If the cable diameter is known, it is possible to directly remove the desired number of layers.

Usually, adjusting the external size of the plug-in cable, etc., is done by using a real cable, since the sizes are often different. In this case, the installation is also facilitated, since it is easier to remove the corresponding number of layers, for example, holding the corresponding protrusion.

In some implementations, the layers may be interconnected using permitted connections. Thus, the peeling layers will be interconnected, which simplifies the work with them.

Thus, one of the objectives of the present invention is to simplify the removal of the correct number of layers by workers. Another goal is to simplify the verification and identification that the installation was carried out correctly.

These problems are solved by means of a part of a sealant or adapter for cables, wires or pipes, designed to insert a cable, wire or pipe. This part is formed by two bases located opposite each other, surrounding a cable, wire or pipe. These bases contain a groove for inserting a cable or pipe in which peelable layers (7, 11) are arranged to form a stack. And at least one of the layers of each foot is marked.

Other objects and advantages of the present invention will become apparent to those skilled in the art upon reading the detailed description below.

Brief Description of the Drawings

The invention will be described in more detail below by way of example and with reference to the accompanying drawings, in which:, Fig. 1 shows a top view of a cable, wire or pipe adapter,

figure 2 shows a General view of a half module that can be used in the transition device shown in figure 1,

figure 3 shows a General view of another seal or adapter for cable, wire or pipe, and

Detailed description of various embodiments

Figure 1 shows the General type of seals or adapters for cables, wires or pipes. It has an external frame 1, mounted in a wall or any other type of partition. Frame 1 has a number of modules 2, each of which is arranged to insert a single-core cable, wire or pipe. In addition, a compression device 3 is installed in the frame 1. The modules 2 are separated by fixing plates 4 installed to securely fix the modules 2 in the frame 1. The modules 2 are compressible parts of the seal or adapter. Each of the modules 2 has a central plug 5 that is removed when inserting a cable, wire or pipe.

The same reference numbers are often used to refer to like parts throughout this description.

An alternative system including a frame is described in a simultaneously filed application entitled “Sealing System” and filed by the applicant of this application. This application is incorporated into this description by reference.

In further alternative embodiments, the sealant, bushing or adapter of the present invention is equipped with a lubricant as described in the concurrently filed application entitled "Lubrication of a pipe or cable entry" filed by the applicant of this application. This application is incorporated into this description by reference.

Figure 2 shows half of the module, which corresponds to the modules 2 in figure 1. Half of the module has a base 6, usually rectangular, having a semi-cylindrical groove on one side. Peelable layers 7 are located inside the semi-cylindrical groove of the base 6. In use, the two halves of the module are joined together so that the grooves coincide with each other. The resulting module will have a central cylindrical hole into which a cable, wire or pipe will be inserted. For example, if you insert a cable, then the corresponding number of layers 7 is removed from each of the bases 6 to fit the inner diameter of the cylindrical hole of the module to the outer diameter of the cable. Thus, when inserting a cable, etc., into module 2, first remove the plug 5, and then remove the layers 7. After all the pipes, wires and / or cables are placed in module 2, the compression device 3 is activated. The task of the compression device 3 consists in expanding in frame 1. Since the compression device will expand, it will press the modules 2 made of a compressible material such as rubber. Modules 2 will compress in one direction and expand in others, pressing modules 2 against frame 1.

Alternative options for the implementation of the modules are given in the simultaneously filed applications: "Eccentric parts of the pipe or cable input", "Pipe or cable input module having grooves on opposite sides", "Pipe or cable input blocks", "Pipe or cable input modules with variable geometry ”,“ Pipe or cable entry with modules assembled from blocks ”,“ Pipe or cable entry having modules with dimension function ”and“ Pipe or cable entry with layers with variable geometry ”, submitted by the applicant for In one embodiment, the modules are separated from the stop halves of the modules fastened together, as described in the simultaneously filed application entitled “Pipe or cable entry modules fastened together in the stops” and filed by the applicant of this application. description by reference.

Figure 3 shows the lower half of one example of a cylindrical seal or adapter. It has a base 8 and fittings 9, 12 at both ends. The base 8 is made of an elastic material and, thus, is a compressible part of the seal or adapter. Between the fittings 9, 12 there are screws 10 passing through the base 8. Using the screws 10, the fittings 9, 12 can be moved relative to each other, compressing the base 8 in the axial direction, while the base 8 will expand in the radial direction both inward and out. To form the seal, the two bases 8 are located opposite each other with the formation of a Central hole. During radial expansion, the base 8 will press inwardly on the cable, wire or pipe, and press outwardly on the hole or sleeve in which the cylindrical seal or adapter is placed. In the sealant shown in FIG. 3, peelable layers 11 are located located on the inner diameter of the sealant, and peelable layers located on the outer diameter of the sealant. The required number of inner sheets 11 is removed to fit the seal or adapter to the plug-in cable or pipe. In the same way, the required number of outer sheets 13 is removed to fit the outer diameter of the seal to the hole or sleeve into which it is inserted.

Each of the individual layers 7 of the half of the module shown in FIG. 2 has a protrusion 14. Also, each of the individual layers 11, 13 of the half of the sealant shown in FIG. 3 has a protrusion 15, 16. The protrusions 14-16 extend beyond the layers 7 , 11, 13 and arranged with uniform displacement relative to each other. The size of the protrusions 14-16, as a rule, is several mm. Thus, it will be relatively simple to take any ledge 14-16. Each of the protrusions 14-16 has a sign identifying the separate layers 7, 11, 13. In the shown example, the signs are made in the form of numbers arranged in ascending order starting with “1”. Specialists know that the signs can be different, in another example, the diametric range corresponding to each of the layers 7, 11, 13 is shown, so that one layer can have a “2-4 mm” mark, the next layer - a “5-7 mm” mark ", and so on. Instead of numbers it is possible to use letters. In yet another example, the markings are assigned different colors to the layers and / or protrusions. It is not necessary to assign different colors to all layers and / or protrusions, but if a limited set of colors is used, they will usually follow in a certain order. Although the protrusions 14-16 are shown only on one side of the half of the module or seal, it should be understood that the corresponding protrusions 14-16 can also be located on the opposite side of the module or seal. The shape and size of the protrusions 14-16 can be different, as well as the size by which the protrusions 14-16 protrude from half of the module or cylinder.

In one embodiment, the protrusions 17 are located strictly beneath each other, but each protrusion 17 projects from the side of the half of the seal slightly further than the protrusion of the adjacent overlying layer. This is shown in FIG.

The embodiment shown in FIG. 5 is similar to the embodiment shown in FIG. 4, but in this case, each of the protrusions 17a protrudes slightly further from the side of the sealant than the protrusion of the adjacent underlying layer. Thus, in this case, the protrusion 17a of the uppermost layer 11 is the strongest. This makes checking easier after installing the seal.

In yet another embodiment, markings 18 are located directly on separate layers, as shown in FIG. 6.

Another example of marking is that each of the layers 11 has a cutout 19, 20 that opens the marking of the underlying layer. Two examples of such markings are shown in FIGS. 7 and 8.

In another embodiment, the protrusions 21, 22 of each second of the layers 11, 13 protrude from one side of the half of the seal, and the protrusions 21, 22 of the remaining layers 11, 13 protrude from the opposite side of the half of the seal. This is shown in FIG. 9.

In the embodiment shown in FIG. 10, each layer has protrusions 23, 24 at both ends of the module.

There may be a table showing what diameter or dimension of the cable corresponds to one or another marking of the layer. Such a table can be applied directly to the side or bottom of half of the module.

In a further embodiment, only a few layers are labeled, for example, those that have protrusions. Often only one, two or three layers are labeled. This arrangement is useful when installing a large number of modules for cables, wires or pipes having the same dimensions, or having only a few different diameters or sizes.

It will be apparent to those skilled in the art that any of the various layer markings given above can be used with a bisected module and a bisected seal, even if these markings are shown here with either a half module or a half seal.

Sheets can be arranged in different ways with different features, which is reflected in simultaneously filed applications entitled "Pipe or cable entry with interconnected layers", "Pipe or cable entry with layers of different thicknesses", "Pipe or cable entry with a part that defines compression" and "The relationship between the layers of the pipe or cable entry" and submitted by the applicant of this application. These applications are incorporated herein by reference.

In use, the number of removable layers 7, 11 depends on the outer diameter of the cable, etc., inserted into the module or seal. In addition, peelable layers 13 located on the outer side of the seal are removed to fit the outer diameter of the seal to the inner diameter of the hole or sleeve in which the seal is placed. If the corresponding number of layers is known, the installer, as a rule, takes the corresponding layer 7, 11, 13 and removes it together with the layers 7, 11, 13 possibly above it. After installation, it is easy to verify that the required number of layers 7, 11 was removed. 13 by checking the marking of the overlying layer 7, 11, 13.
