Description

SEALED CONNECTOR OF MULTI-CABLE CABLES.

The utility model relates to electrical engineering, namely to hermetic connectors of multicore cables, which operate for a long time in marine conditions at high hydrostatic pressures.

The utility model can also be used in the national economy for underwater and surface devices with multi-element lines of electrical communications of high reliability for long-term operation in afessive environments.

Currently, connectors of multicore cables in a monolithic rubber casing are widely used because of their resistance to impact: high hydrostatic pressures in deep water conditions, aggressive liquid and gaseous media, mechanical loads, shock and vibration (see, for example, 1, 2).

According to the set of features, the closest to the proposed utility model is a sealed connector of multicore cables, described in 1 drawing 7 p. 67.

The prototype connector contains isolated insulated solder joints of conductive core connections, screen wires are wrapped on the hose shells of the cables to be connected, copper braces are laid on them, braces are brazed, braced} | A1 sections of the cables to be connected are electrically connected by a jumper from the mounting wire, the fastening of which is done but soldering.

The disadvantage of such designs of connectors is the low strength of the soldered nodes of the connections of conductive conductors and ethanes. And the strength of wires of conductive conductors and screens during soldering decreases due to diffusion of solder into the material of the wires, leading to embrittlement of the material of the wires on the solder plate. During press operations, when the viscous mass of the rubber compound fills the annular space, the brazed joints of the conductive conductors and ethanes are subjected to mechanical stresses that exceed their strength. This leads to a violation of the integrity of electric circuits.

The technical result of the utility model is the hardening of the joints of conductive wires and screens, reducing the complexity and reducing the length of the connector.

To achieve the specified technical result, new signs are introduced into the hermetic connector of multicore cables in a hose sheath with insulated conductors placed in a wire screen, containing soldered soldered nodes of pair-wise connection of conductive conductors and soldered pair-wise connection of ethane conductors, installed in a rubber array, namely, the connection of each pair of conductive conductors is made by twisting, the twist of the conductive conductors of each pair is sealed from the end, bent along the first conductive core is placed in an insulating tube, while the section in the insulation of the first conductive core of each pair has a spin equal to that of the insulation tube, and the length of the section without insulation of the second conductive core of this pair exceeds the length of the section without insulation of the first conductive core of the pair by the length of the wire, with the wire screens of both the cables are twisted into bundles and twisted in pairs, twisting the bundles of each pair is sealed from the end and scuffed onto an insulating tube along its axis.

The achievement of this effect is explained by the following: Kanodai a pair of connected conductive conductors and ethanes connected by a wire and soldered only from the end. In this case, the soldered joints and the embarrassed part of the wires of conductive conductors and ethanes on the fan with soldering are mechanically deflated, and the proposed design of the connector allows the cable to be technologically and reliably extended without increasing the length of the connector.

The essence of the utility model is illustrated in FIG. 1 and 2, where figure 1 schematically shows the design of a sealed connector of multicore cables.

The connector contains cables 1, insulating tubes 2, a section in the insulation of the first conductive core of the core 3, ethane from the wire 4, a section in the insulation of the second conductive 1a1la 5, a rubber mixture 6, a bandage of calorie thread 7, bundles of ethane wire 8, a section without insulation of the first conductive cores 9, section without insulation of the second conductive core 10, the area of the conductive wires 11, the area of the bundles of ethanes 12.

the insulation is removed from the conductive conductors, so that the section in the insulation of the first conductive core 3 becomes equal to the length of the insulating tube 2, this allows you to place an insulating tube on it before twisting the conductive conductors without insulation, and the section without insulation of the second conductive core 10 should be longer than the section without insulation of the first conductive conductor 9 to the length of the conductor conductor 11, the wires of conductive wires and shields are washed from the sealant and cleaned, the original conductive core is restored and twist the wire harnesses from the screen wire, then place the insulating tube 2 on the section in the insulation of the first conductive core 3, twist the conductive uylls of sections 9 and 10 so that the twist unit 11 is removed from the insulation plate of the second conductive core 5 by the length CKpyTioi 11, this allows you to lay C1 foot along the axis of the conductive wires to be connected, soldered from the end (yoke 11, Fig. 26, then lay the twist 11, push the insulating tube 2 onto the connection node of the conductive wires, restore the screening of the insulator freed from onnoy tube portion of the first conductor in the insulation 3 and the fixed screen shroud nylon thread 7 strands twisted pairs E1fanov, skrulsu solder 12 with its end and is placed on the surface of the insulating tube 2 along the axis of the insulating tube. FIG. 2c.

At the same time, the quality and reliability of the connector are significantly improved while reducing labor intensity (it is not necessary to vulcanize a multi-seat insulating separator) and reducing the length of the connector by about 2 times, which is important for performing vulcanization of the connector in conditions of limited access to cable splices.

Based on the foregoing, we can assume that the utility model solves the problem.
