Description

Technical field

The utility model relates to electrical engineering and can be used for wiring cables on walls and ceilings of buildings, preferably household electrical wiring, of any type.

State of the art

A device for attaching electrical wires containing a support with a hole, for example, for a nail, fixing the support on the wall, and adjacent to the support grip with a groove to accommodate a fixed electrical wire (patent of the Russian Federation for invention No. 2273931 according to class H02G 3/32 from 04/10/2006). Using such a device, it is convenient to fasten one or two wires, but such a device is inconvenient for fastening in one zone a large number of wires of a branched network.

A device for attaching electrical wires containing a support and a holding part attached to the support is known. The support is made in the form of a cylinder immersed in a hole in the wall. The holding part is a longitudinal shelf fixed perpendicular to the support. Along the outer surface of the shelf there is a tool tray for placing the wire. The wire is laid on the lodgement and fastened to it by a tightening tape covering the wire and the lodgement (US patent No. 6320134 according to class Н01В 7/00 of 11/20/2001). This device can be used to form a ruler for mounting any number of wires by sequentially mounting the supports on the wall. However, the formation of such a line requires an individual hole in the wall, which greatly complicates the installation of wiring, especially if the fastening zone has to be formed directly in place.

The closest technical solution is a comb for mounting electrical wires, comprising at least one module for mounting electrical wires, including a mounting rail having a support base, a front surface, two ends located opposite each other on both sides of the rail, and two lateral surfaces extending between the ends, while the module is equipped with lodges for fastening the electric wire, pairwise connected to the side surfaces of the module, and in the mounting rail is made, of at least one through-hole extending transversely to the mounting rail from its front surface to the support base, a module designed for the fastening member when installing combs. The wire is attached to the lodgement with cable ties covering the fixed wire and the tab. This comb is described in the prospectus “Cable entry systems. EMC Products. Section 3 Cable fastening systems, pages 68-72 ”(aetec.ru> files / icotek_Catalogue27_ru.pdf). This comb allows you to effectively form a fastening zone of almost any length by installing a chain of modules directly in the fastening zone. However, when forming a line of separate modules when attaching a separate module in a chain, it is necessary to manually hold the module in a predetermined position relative to the fixed module in order to form an aligned chain of modules, which complicates the procedure for attaching electrical wires, especially if the wiring is fixed on a vertical wall or ceiling.

Utility Model Disclosure

This technical problem is solved by a real utility model, in which a modular comb is proposed, which will provide the best installation conditions and simplify the mounting of mounting rails on the wall, ceiling, vertical support or any other surface chosen for wiring.

To solve this problem, a modular comb for attaching electrical wires is proposed, comprising modules for attaching electrical wires, each module including a mounting rail having a support base, a front surface, two ends located opposite each other on both sides of the rail, and two lateral surfaces extending between the ends, lodges for fastening the electric wire, attached to the lateral surfaces of the mounting rail, in which the module is equipped with connecting elements and forming a quick disconnect located on the ends of the mounting rail, with the possibility of sequentially connecting the modules to each other, the first quick connect element is located on one of the ends of the mounting rail of the module, and the second quick connect element responding to it is located on the opposite end of the mounting rail of this module with the possibility of forming a quick disconnect connection with the first element at the end of the mounting rail of an adjacent module.

In addition, in the proposed modular comb in a quick coupler, the first element is made in the form of a groove on one of the ends of the mounting rail, extending in a direction parallel to the front surface of the mounting rail, and the second element is made in the form of a protrusion on the opposite end of the mounting rail, extending parallel to the front surface mounting rail, while the outer contours of the protrusion repeat the inner surface of the said groove.

Moreover, in the proposed modular comb, the groove can be made through, the groove can be made open on one side and completely or partially closed by a transverse partition on the opposite side.

In addition, in the proposed modular comb, the protrusion can be made with a length corresponding to the length of the groove, and extends parallel to the groove at a distance equal to the length of the groove to the transverse partition.

In addition, in the proposed modular comb, the protrusion can be equipped with a shelf resting on the input edges of the groove.

In addition, in the proposed modular comb in a quick disconnect connection, the groove can be made with a variable width of the cross section, and the protrusion is made with a variable width of the cross section, in accordance with the cross section of the groove.

In addition, in the proposed modular comb in the quick coupling, the groove and protrusion form a quick coupling in the form of a dovetail.

In addition, in the proposed modular comb in the quick-connect connection, the protrusion and groove can be made with a T-shaped or L-shaped cross-section.

In addition, in the proposed modular comb, the lodgement can be equipped with a protrusion placed on the end of the lodgement and extending in the direction of the support base of the mounting rail.

In addition, the modular comb can be equipped with additional tool holders for attaching electrical wires located along one side surface of the mounting rail.

In addition, the modular comb can be equipped with additional tool holders for attaching electrical wires located on both sides of the mounting rail.

Moreover, in the proposed modular comb, the lodges can be made with the same lodgment width or they can be made with different lodgment widths.

In addition, in the proposed modular comb, lodges on the lateral surfaces of the mounting rail are located opposite each other.

In addition, in the proposed modular comb, the lodges on one side surface can be offset relative to the lodges on the opposite side surface.

The technical result from the use of the utility model is that the utility model provides preliminary quick fixation of the mounting rails of two adjacent modules by equipping them with quick couplers containing two elements forming a quick coupler, while the first element of this connection is fixed to one end of the mounting rail, and the second element of this connection interacting with it is fixed on the other end of the mounting rail and, when assembling the line of mounting rails, two adjacent ends of these the rails contain the first and second quick-connect elements facing each other, which provides preliminary fixation of two adjacent mounting rails, limiting their mobility relative to each other, simplifying the coordination of the relative positions of these two rails when forming a line of mounting rails and fixing the second mounting rail to the wall.

In a quick coupler, the first element is made in the form of a groove on one of the ends of the mounting rail, extending in a direction parallel to the front surface of the mounting rail, and the second element is made in the form of a protrusion on the opposite end of the mounting rail, extending parallel to the front surface of the mounting rail, with external contours protrusions repeat the inner surface of the said groove, which provides easy docking of two adjacent modules and keeping them in a docked state.

The execution of the groove open on one side and completely or partially closed by a transverse partition on the opposite side simplifies the connection of two adjacent modules, since the relative position of two adjacent modules is clearly fixed.

The fast and clear fixation of the quick coupler elements relative to each other is facilitated by the implementation of the protrusion with a length corresponding to the length of the groove extending parallel to the groove at a distance equal to the length of the groove to the transverse partition, and equipping the protrusion with a shelf resting on the input edges of the groove.

The execution in the quick-connect connection of a groove with a variable cross-sectional width, and a protrusion with a variable cross-sectional width, in accordance with the groove cross-section, ensures reliable fixation of the protrusion and groove relative to each other, while the proposed cross sections of the protrusion and groove are “dovetail” or T-shaped or L-shaped cross sections are easily joined and well mastered by the industry.

Performing a through groove provides the simplest connection of the quick disconnect elements, while fixing the two elements can be achieved by any known method, for example, jamming two adjacent elements, or a shelf on the protrusion, as described above.

Equipping the tool tray with a protrusion located on the tool tray end and extending in the direction of the mounting base of the mounting rail provides reliable fixation of the wire on the tool holder, eliminating its displacement after fixing.

The proposed design of the comb module ensures the presence on any mounting rail of any required number of tool holders with any width of tool holders and with any of their complete sets on one mounting rail, which makes it possible to assemble a comb for mounting wires in any configuration directly when fastening the wires and easily mount such a comb on the wall.

Module 2 contains a mounting rail 4 with two similar (wide) tool holders 5 located on two sides of the mounting rail 4. Module 3 contains a mounting rail 6 having several tool holders for attaching wires: four narrow tool holders 7 on one side of the mounting rail 6 and three wide lodgements 5 on the other side of the mounting rail 6. It should be understood that the number of lodges on one rail may be the same or different on the two sides of the mounting rail, it is not necessary that the lodges on one side The mounting rails were the same size. In particular, the number of lodges on a mounting rail can vary from one lodgment with a one-sided arrangement of a lodgment on a mounting rail, to twenty or more lodges with a two-sided arrangement of lodges relative to the mounting rail. Accordingly, the total length of the mounting rail changes, starting with a mounting rail 15–25 mm long for a mounting rail with one lodgment on one side of the mounting rail or two lodges with a two-sided arrangement of lodges. With a large number of lodgements, the length of the mounting rail can reach 120-150 mm or even more. Usually, the length of the mounting rail increases by 10-15 mm when adding one additional lodgement to the mounting rail (provided that a new lodgement is added from the side already filled with lodges).

The lodges for fastening the wires can be located on both side surfaces of the mounting rail opposite each other, for example, wide lodges 5 on the mounting rail 4, or they can be offset relative to each other, for example, wide lodges 5 and narrow lodges 7 on the mounting rail 6.

In FIG. 1B shows an example of attaching an electric wire to a comb. For simplicity, one wire is shown to be fixed, but as many wires can be fixed as there are mounting cradles in the mounting rail. You can fix the wire on one lodgement, as shown in FIG. 1B, but you can fix the wire on both lodges. To fix the wires of the wire on the tool tray, you can use any known means: coupling clamps, tapes, elastic split rings, etc.

Next, preferred versions of mounting rails in accordance with this utility model will be described.

The hole 14 is intended to be placed I'm in it the module attachment element 2 against the wall when installing the module. As a rule, the hole 14 has a stepped shape, while the portion of the hole with a large diameter is located on the front side to form a support flange for pressing the mounting rail to the wall surface or to any other mounting surface (ceiling, floor, supporting structure, etc. ) The hole 14 may also be cylindrical or include a tapering conical section. In the hole 14, a metal sleeve 15 can be installed with an outer surface that matches the contour of the wall of the hole 14. Preferably, but not necessarily, the metal sleeve 15 is mounted flush with the support base 8. In this embodiment, one through hole 14 is made in the mounting rail 4, located , preferably, but not necessarily, in the central area of the mounting rail, however, two holes (or three to four holes) can be made in the long mounting rails for mounting the mounting rail to the wall.

Module 2 is equipped with connecting elements forming a quick disconnect connection, with the possibility of sequential connection of modules to each other. The connecting elements are located at the ends of the mounting rail, while the first quick disconnect connection element is made in the form of a longitudinal groove 16 extending in a direction parallel to the front surface 9 of the mounting rail 4, and is located at one of the ends, for example at the end 11, of the mounting rail 4 of the module, and the second quick-connect element is made in the form of a longitudinal protrusion 17, extending parallel to the front surface 9 of the mounting rail 4, located on the opposite end 10 of the mounting rail 4, while external to ntury longitudinal protrusion 17 is repeated an inner surface of said longitudinal slot 16.

Preferably, the longitudinal groove 16 is made open on one side, has walls 18 forming the lateral surface of the longitudinal groove 16, and a transverse partition 19 completely or partially covering the longitudinal groove 16 from the opposite side.

In this embodiment, the longitudinal protrusion 17 is made with a length corresponding to the length of the longitudinal groove, and extends parallel to the longitudinal groove at a distance equal to the length of the longitudinal groove to the transverse partition. The longitudinal protrusion 17 may be equipped with a shelf 20, leaning upon connecting to the adjacent module on the input edges of the longitudinal groove 16 of this adjacent module. Shelf 20 may be double-sided or single-sided.

In this embodiment, in the quick disconnect, the longitudinal groove 16 is made with a variable cross-sectional width, and the longitudinal protrusion 17 is made with a variable cross-sectional width, in accordance with the cross-section of the longitudinal groove. Preferably, the longitudinal groove 16 and the longitudinal protrusion 17 form a dovetail quick coupling.

In FIG. 6 shows a modification of module 2 according to the first embodiment, in which the longitudinal groove 16 is made through and the longitudinal protrusion 17 extends along the entire end face 10 of the mounting rail 4.

In FIG. 7 shows another modification of module 2, in which the mounting rail 4 is equipped with lodges attached to only one side surface of the mounting rail 4. This example shows one wide lodgment 5, but it is possible to attach several wide or narrow lodges or a combination thereof.

The dimensions of the longitudinal protrusion 17 and the longitudinal groove 16 are selected depending on the specific conditions. In particular, the longitudinal protrusion 17 can freely enter the longitudinal groove 16 or for its introduction into the longitudinal groove and the removal of the longitudinal groove 16 requires some force that is able to hold the longitudinal protrusion in the groove.

Example 2 (second embodiment of the utility model)

In FIG. 8-12 show a second embodiment of a modular comb for attaching electrical wires in accordance with this utility model. When describing this performance, a detailed description of the individual features of this performance related to features matching the first performance example will be omitted.

As shown in FIG. 8, the modular comb 1 comprises two modules 2 connected to each other. The difference between this embodiment and the first example described above lies in a different embodiment of the quick coupling.

In this embodiment, in the quick disconnect connection, the first quick connect element is also made in the form of a longitudinal groove 16 extending in a direction parallel to the front surface 9 of the mounting rail 4 and is located at the end 11 of the module mounting rail, the second quick disconnect element corresponding to it is made in the form of a longitudinal protrusion 17, extending parallel to the front surface 9 of the mounting rail 4 and is located on the opposite end 10 of the mounting rail. As shown in FIG. 8-12, the longitudinal protrusion 17 of one module 2 and the longitudinal groove 16 of the adjacent module 2 form a quick coupler.

In contrast to the first embodiment described above, the longitudinal protrusion 17 and the longitudinal groove 16 are made with a T-shaped cross section. The longitudinal protrusion 17 contains a longitudinal rib 21, preferably located in the middle zone of the end face 10, and a shelf 22 along the outer edge of the longitudinal rib 21. Accordingly, the walls of the longitudinal groove 16 have longitudinal elements 23, which are usually symmetrical on both sides relative to the longitudinal the axis of the end face 11, and the shelves 24 along the outer edge of the longitudinal elements 23, protruding in the direction of the longitudinal axis of the end face 11. The longitudinal projection 17 can be made with any reasonable thickness of the longitudinal rib 21 and any reasonable floor dimensions and 22 are determined primarily by the strength requirements of the quick coupling. The shelves 22 may have a rectangular cross-sectional shape with an equal thickness of the shelf, but this shape of the shelf 22 is optional, and the shelf 22 may be made with a variable cross-section, for example, the shelf 22 may have a shoulder 25 of any shape along the outer edge of the shelf 22 (shoulder can be made rectangular, triangular, trapezoidal or any other). Accordingly, the flange 24 of the wall of the longitudinal groove is made with a cross-sectional shape corresponding to the cross-sectional shape of the flange 22, and has a shoulder 26 to engage with the flange 22.

In FIG. 8-12 shows a comb module 2 for securing wires in which the longitudinal protrusion 17 and the longitudinal groove 16 have a T-shaped cross section, however, it should be understood that the longitudinal protrusion 17 and the longitudinal groove 16 can have any other cross section, for example, G- cross-sectional shape, or any other cross-sectional profile - cross-shaped cross-section, etc.

In FIG. 8-11, as an example, a module 2 is shown in which there is no metal sleeve in the hole 14, however, it is understood that in this configuration, if necessary, the metal sleeve 15 can be installed in the hole 14, as shown in FIG. 12.

It should be understood that all modifications of the implementation of the first and second elements of the quick coupler (through longitudinal groove 16 and longitudinal groove 16 with a partition, a longitudinal protrusion 17 with a shelf and without a shelf, etc.) from the first embodiment of the utility model are applicable to the second embodiment.

In addition, in the proposed comb, the lodgement can be equipped with a protrusion 26 located on the end of the lodgement, extending in the direction of the support base of the mounting rail. The protrusion 26 provides quick fixation on the lodgement of the coupling collar, drag tape or any other known means of fastening.

The above examples are not limiting, and other modifications of quick couplings may be proposed as part of the utility model formula.

It should be understood that this description is only to illustrate the implementation of the utility model and in no way limits the scope of protection of the present utility model.

When attaching the electric wires, a comb module is selected that has the required number of lodgements, the mounting rail 4 or 6 is fixed, for example, on the wall in the installation area with screws or other fixing elements passed through holes 14. The fixed wire is laid on one of the lodges 5 or 7 and fixed it with the help of, for example, a drag tape covering the tool tray and the wire to be fixed. If it is necessary to extend the fastening zone, the second module is selected, using a quick-connect on the adjacent ends of the mounting rails of the connected modules, attach the second module to the first module, ensuring its fixation relative to the first module, which facilitates the subsequent action, since there is no need to hold the second module when fixing it to wall, and easily mount the mounting rail of the second module on the wall, extending the comb.

You can use other wire fastening technology. Two (or more) comb modules are selected, quick connectors are used at the ends of the mounting rails, the selected modules are connected in a chain to form a comb for attaching the wires, and the assembled comb is mounted on the wall as described above. There is also no need to hold the second module when it is mounted on the wall, since it is fixed simultaneously with the first module. It should be noted that to secure the assembled comb, you can do with fewer screws or other fasteners.

For mounting the mounting rail, any other mounting means can be used, in particular, any grips can be used to mount the modular comb on any type of DIN rail.
