    The assembly comprises an internally threaded sleeve (35) having at least one open end and a flanged body or bodies (21) having an externally threaded shaft portion (23) adapted to be screwed into the or each open end of the sleeve (35), and an outer flange portion (24). The or each flanged body (21) has an axial bore (26) through which the end of a conductor (30,31) is passed into the sleeve. The interior of the sleeve contains a plastic sealing compound (37). When the flanged body or bodies is or are screwed into the sleeve, the sealing compound is compressed and is forced into the threads to seal the end or ends of the sleeve. Adjacent the flange portion (24), the shaft portion (23) of the or each flanged body is provided with a region of greatly reduced cross-section, e.g. by means of a peripheral groove (39). Further screwing in of the or each flanged body causes the flange portion thereof to break off, thus rendering the termination or connection permanent. <IMAGE>

    D 12 17 P Fi9.2 c 1 The invention relates to electrical engineering and can be used to hermetically connect or seal electrical wires to a formation with mason insulation. The purpose of the invention is to simplify installation. FIG. 1 shows a scheme for carrying out the method; FIG. 2 shows the connection in the mounted all-in-one state; on fig.Z - flange test ka. The method of hermetically connecting the ends of the electrical wires is carried out as follows. The wires 1 and 2 with plastic insulation, for example, made of polytetrafluoroethylene, are to be spliced, plugs 3 and 4 are put in. The plug has a flange 5, a cylindrical barrel 6 with a thread 7 and an axial channel; wire passes. At one of the wires at the same time put on performed in the same way as the tube of temperature-resistant plastic based on polymers that are not obtained from the melt, such as tetrafluoroethylene, the housing 9 of the sleeve is cylindrical. After the conductor cores 10 and 11 are connected with the clamping sleeve 12, as well as the shields 13, these connections are placed in the longitudinal grooves 14 of the additional guide body 15, which secures the connection and separation of the wire elements to be connected. After that, the stopper 3 is partially screwed into the housing of the coupling 9 and liquid filling material 17 is poured from the container 16 approximately up to the Levina of the internal cavity of the housing 9 ryphas. Then the guide housing 15 is drawn into the housing 9 to the stopper 3 and topped up with an additional portion of the filling material to the top of the housing 9 coupling. The plug 4 is installed from the other end of the housing 9. By further inserting the flange plug into the coupling housing, the filler mass enters into the cavities inside the coupling housing and into the thread. By screwing the flange plugs into the coupling housing, pressure is applied to the filling mass. In this case, it was expedient to perform threading 18 along the entire length of the coupling housing. Inaccuracies in the dosage of the filling mass can be compensated by the corresponding 162 further wrapping of flange plugs. The opening 19 in the coupling housing 9 serves to allow the air remaining inside the coupling to escape and, moreover, performs a monitoring function. The excess filler material is squeezed out through the opening 19 to the outside and the material is a guarantee that the inside of the coupling is indeed filled. The filling mass 17 also enters the recesses 20 in the ends of the salvol, the plugs, preventing the flange plugs 2 and 3 from self-opening. Therefore, the connection can be called self-locking. Further rotation of both plugs is carried out before their flanges 5 are folded by counter-pressure of the filling material, which is in the liquid state at the room temperature. In this way, the resulting moisture-tight connection is protected from opening the plugs. The cut-off point at the end of the plug stem when exceeding the maximum torque is determined by the stipulated attenuation of the cross-section of the plug in the flange zone, which can be obtained by a circular groove 21 with a depth exceeding the depth of the thread profile or in the form of one or several tangentially passing to the surface of the barrel grooves, or grooves with a depth that exceeds the depth of the thread. In order to provide ease of screwing in, the flanges of the plugs can be of a section other than a round shape (for example, a lock-key). As a filling material, a fully polymerized or partially polymerized, or non-polymerized mass based on silicone rubber can be used. The partially polymerized silicone rubbers are especially beneficial in combination with the coupling housing and the fluoropolymer flange plug, because without pre-treating the surfaces, good adhesion at the border is obtained. Conventional casting resins can also be used, which, after solidification, give a compact joint, and by penetrating the profile or into the threads of the thread due to the resulting multitude of successive labyrinths, also provide the required tightness. The sealing effect can be improved by choosing the shape of the inner and outer threads to be acute angle. At the same time, the length of the path in labyrinths increases and their efficiency increases. Since the wires are passed through axial channels in the flange caps, in order to get better sealing in this part, the channels in the trunk area on the surface facing the wire can be provided with sealing elements, for example, in the form of so-called sealing lips 22, It is sometimes advisable to carry out a flow in a flange plug for a wire in the area of the trunk with an increased diameter. This ensures that the end of the wire is securely fastened in the transmission area. In the case of end fittings, temperature sensors and limiters can be contained in the shaped housing together with the connection of the wires. They can, for example, interrupt the current circuit if a certain temperature value is exceeded in the event of a defect. In this case, it may be advisable to use a cylindrical shaped body that is open only on one side, and the open end serves for inserting, for example, measuring; A solid probe with a corresponding connecting wire, as well as for inserting a flanged plug after inserting the filling material. Thus, assembling an installation in accordance with the invention allows, by simple means, to connect or seal electrical wires having 1164 high tightness, heat resistance and mechanical strength practically anywhere along the route of the wires. Formula and Gains 1. A method of sealingly joining or sealing the ends of electrical wires with plastic insulation, consisting in installing a coupling into the place of installation in the form of a cylindrical shaped body, covering part of the length of the wire in the insulation, inserting it into the cavity of the sleeve of the filling material and creating pressure on the filling material in the liquid state by axial movement relative to the body of the plugs installed on its end sides with flanges, cylindrical barrel and axial channel ohm for the passage of wires, characterized in that, in order to simplify installation, the filling material is introduced into the coupling housing in a liquid state after the housing is installed at the installation site and the plugs are made with a weakened cross section in the flange area by screwing them into the housing before the flanges of the plugs coagulate with the counterpressure of the filling material, which is in a liquid state at the room temperature.

    2. A pop method, 1, characterized in that corks are used which have a recess at the end of the barrel. 3, Pop method, 1, is distinguished by the fact that corks with sealing elements are used, in the axial channel in the zone there are located a trunk.
