Abstract

FIELD: electricity.

SUBSTANCE: universal pressure seal separator relates to on-board cable networks and means of their sealing. Pressure seal separator consists of two identical interpenetrating half-bodies. Semi-body consists of base (1) and protruding part (2). Base (1) of the semi-body has a hole for cable laying, bundles, wires in the pressure seal and hole (5) for installation of the fixing element at routing of cables, bundles or wires. Extending part (2) of semi-body has notch (3) to exclude mutual slippage of body parts and rounded central channel (4). Central channel (4) corresponds to the shape of round or flat layout of the laid cable, bundle or wire and has rounding to exclude rubbing of the cable, bundle and wire. Seal (6) and mounting plate (7) are installed on protruding part (2) of semi-body at installation of pressure seal separator. Mounting plate (7) can have zero, one or two attachment points with direct location of fasteners, with location at an angle.

EFFECT: use of the universal pressure seal separator ensures safe and tight passage of the cable assemblies together with the connectors through the holes in the structures, fastness and convenience of the cable through the hole, and, if necessary, provides a simple and cheap method for mutual connection and physical separation of different bundles, cables, wires running at an angle to each other.

Description

The invention relates to on-board cable networks and their sealing means and can be used when laying cable networks to ensure a tight passage of cable, bundle, wire through the walls without preliminary assembly operations of the cable gland with a cable, bundle or wire, as well as when wiring cable networks for decoupling the cables , harnesses, wires relative to each other.

Hermetic inlets and cable glands of the PG type (for example, manufactured by Techelectro, http://techelectro.ru/prod/in/pg/), consisting of a housing, a lock nut, a gear coupling and a cap-nut, are known from the prior art.

The main disadvantages of PG type cable glands and cable glands are the complexity of the multi-part design, the need to first put part of the cable gland on the cable from different sides of the wall, followed by soldering the connectors “in place” due to the inability to pass through the cable gland parts.

Known seals of the prior art are KVT type oil seals (for example, Icotek, http://ntcontact.ru/product/464), consisting of two releasable parts and a fixing nut.

The main disadvantages of these split glands are the need for preliminary putting on the cable or the harness of the nut, as well as the lack of sealing properties, the complexity and unreliability of assembly, high cost.

Cable glands of type SR (for example, manufactured by KSS Wiring, https://www.tme.eu/ru/details/sr-6p1/vvodyvyvody/kss-wiring/), consisting of two unequal parts connected by a flexible connection, are known from the prior art . The main purpose of SR type cable glands is to protect the cable from sharp edges.

The disadvantages of cable glands of type SR are their orientation to wall thickness, inconvenience of closure, poor fixing in the wall and lack of sealing.

The prior art method for knitting mutually perpendicular harnesses in accordance with OST 1 00239-77. The main disadvantage is the complexity, inconvenience, unreliability and complexity of the method, the lack of rigid fixation.

A cable gland of the V-TEC type (for example, ATEX Electro, http://cmp.atekselectro.ru/), consisting of a detachable case with a split seal and a detachable nut, was taken as a prototype of the pressure seal.

The main disadvantages of V-TEC type cable glands are the complexity of the design and the unreliability of the lock nut when tightening, the possibility of spontaneous opening, and high cost.

As a prototype of the cable separator, a cable separator of the Amphenol ABS1144 type (for example, https://www.amphenol-airlb.de/38.0.en.33.html), consisting of two cable supports for a nylon cable tie located at 180 ° in relation to to each other so that one cable runs from below and the other from above.

The main disadvantage of this cable splitter is the high cost and complexity of the design in manufacture.

The objective of the invention is to provide a safe and tight passage of cable assemblies together with connectors through openings in structures, speed and convenience of cable routing through an opening, and, if necessary, providing a simple and cheap way to interconnect and physically separate different bundles, cables, wires going at an angle to each other.

The technical result in the field of safe and tight passage of cable assemblies together with connectors through the holes in the structures is achieved by the fact that the invention consists of two identical interpenetrating parts that together form their outer diameter corresponding to the diameter of the hole for the connector passage in the wall and inner diameter pressure gland corresponding to the diameter of the cable, harness, wire. Due to the construction of the invention, the thickness of the passage wall can vary in a certain range corresponding to the size of the pressure seal. The diameters of the through-hole in the wall and the diameters of the cable, bundle, wire can be determined by the hermetic input parameters and selected from the line of standard sizes. Perhaps the use of color marking sizes.

The technical result in the field of providing a simple and cheap method of interconnection and physical separation of various bundles, cables, wires is achieved by the fact that one cable, bundle or wire passes through the internal opening of the invention, and the other lies in the lodgement formed by two half-cases and is secured with a tie.

The invention is illustrated in figure 1.

The location of the cable in the pressure seal is shown in FIG. 2.

The design of the pressure seal is illustrated in FIG. 3: a - view of the outer part of the half-shell; b - view of the inner part of the half-housing; in - a different form of the central channel; g - the use of a pressure seal-separator as a separator.

The assembled isolator-isolator is illustrated in FIG. 4: a - assembled with an installation plate for two mounting points located at an angle of 180 °; b - fastening the pressure seal-isolator with cable to the wall.

A single point mounting plate design is illustrated in FIG. 5

The design of the pressure seal with a mounting plate for two points located at an angle of 90 ° is illustrated in FIG. 6

Structurally, the invention consists of two identical parts interpenetrating each other (Fig. 1), each of which includes a half-housing with a protruding part having a notch to prevent mutual slipping of the housing parts and their spontaneous opening and a central channel of arbitrary shape for laying the cable, the bundle , wires (Fig. 2).

Half housing (Fig. 3, a, b) is a product structurally consisting of a baseonehaving an opening for laying cable, harness, wire in the pressure seal, and the protruding part2notched3 to avoid mutual slippage of the parts of the housing having an external size and shape corresponding to the passage hole in the wall, as well as the Central channelfour (half-hole), corresponding to the external dimensions and shape (round or flat layout) of the laid cable, bundle, wire (Fig. 3, c). The edge of the hole has a rounding to prevent chafing of the cable (harness, wire). Also a half-shellone may have a through hole5 for installation (threading) of the fixing element when wiring cables, bundles, wires (Fig. 3, g).

In assembled form (Fig. 4, a) the invention is two half-bodies with split seals 6 , located in relation to each other with central symmetry; spaced apart by a wall thickness. For fixing to the wall, the pressure seal may have a mounting plate 7 , attached to the wall 9 by the fastening element 8 (Fig. 4, b).

An optional pressure seal can be supplied without a mounting plate (Fig. 1) or with a mounting plate 7 on one (Fig. 5), two mounting points with a direct mounting location (Fig. 4, a), with an angle (Fig. 6).

Color coding. The size of the product (external and internal diameters, the shape of the through hole) in the ruler can be determined by the color of the material of the half-body of the pressure seal and the seal.

The use of the invention provides a simple safe and tight passage of cable assemblies together with connectors through openings in structures, the speed and convenience of cable through a hole, and, if necessary, provides a simple and cheap way to interconnect and physically separate the various bundles (cables) that go under angle to each other.
