Furthermore, a connection material for data transmission comprising such a device is specified.

Description

The present invention relates to a device for guiding at least two lines. Furthermore, the invention relates to a connection material for data transmission comprising such a device.

From practice it is known to connect electrical lines by means of different connecting elements such as cable ties, adhesive tape, etc. together to guide the lines ordered. For this purpose, the electrical lines are connected to the connecting elements in more or less regular intervals. Furthermore, cable ducts - for example, on office furniture - known, which serve to guide the electrical lines.

Especially with electrical cables of powerline communication systems special requirements apply to the management of electrical cables. In powerline communication systems, a power supply network is used to exchange communication signals between the participants in the system. The signals or data to be transmitted are modulated in the higher frequency range on one or more lines of the power supply network, for example, to a phase relative to the neutral conductor or between two phases. For example, the broadband variant of Powerline Communication - Broadband Powerline (BPL) - often uses signal components in the frequency range between 1 and 30 MHz.

In the case of the leads of the connection material, which serves for coupling or decoupling a BPL signal from an electrical system, it is necessary to guide them in the most exact possible alignment with one another. This is problematic in that, in particular, the portion of the connection material which is coupled to an electrical system, for example a road distributor, is present as individually routed, separate lines. Since the leads of this section are not in a defined position relative to each other, the wave impedance of the leads increases, resulting in sometimes severe attenuation of the BPL signal.

Merging the individually guided lines by means of cable ties, adhesive tape, etc. is problematic because the electrical system is regularly under tension when the installer connects the lines to the system. Protective gloves are worn by the fitter and the available space is very cramped, so that the work with tape, cable ties, etc. is extremely difficult.

Furthermore, it is due to the above-described working conditions, it is difficult to reopen these fasteners to separate the interconnected lines from each other, especially since there is a considerable risk of injury to the fitter due to the applied voltage. Another disadvantage is that the lines have a defined distance from each other only in the region of the connecting elements. Thus, the distance of the lines varies over the length, which has a negative effect on the wave impedance and thus the attenuation of the BPL signal.

The present invention is therefore based on the object of specifying a device for guiding at least two lines, in which a structurally simple means a leadership of the lines in a defined distance from each other is possible. Furthermore, a connection material with such a device should be specified.

According to the invention the above object is solved by the features of claim 1. Thereafter, a device for guiding at least two lines, in particular for data transmission, specified, comprising a base body for receiving the lines, wherein the base body at least partially has a longitudinally extending slot, wherein a slider is arranged on the base body, wherein the slider along the longitudinal direction of the body is movable and wherein at least one of the lines by means of the slider through the slot in the body can be introduced and / or ausbringbar from the body.

In accordance with the invention, it has first been recognized that the lines can be guided in a defined position relative to one another in a simple manner by the arrangement of a main body receiving the lines. In a further inventive manner, the base body has a slot extending in the longitudinal direction of the main body, through which at least one of the lines can be introduced into or out of the main body. In a sophisticated manner, a slider is provided for this purpose, which is movable along the longitudinal direction of the base body and is pressed over the at least one of the lines through the slot in the body and / or pulled out of this, depending on the direction in which the slider is moved. By this constructive measure, the device is very easy to handle, even in a confined space and with protective gloves. Thus, cables can be extremely simple in a defined position to each other and also remove each other or solve, so that the device is extremely flexible and also a multiple use is possible. Another advantage is that the standing in contact with the slide line is secured by the slider at least slightly against further extraction and / or introduction into the body.

It should be noted that the main body is advantageously formed in one piece. However, it is conceivable that the base body consists of several individual parts. It is essential that the lines located in the body are guided in a defined position to each other and that at least one of the lines through the slot in the body or a cavity formed in the body and can be introduced from this.

By a slot is meant an opening that is sufficiently large to pass a conduit. Advantageously, the edges of the slot may be at least slightly biased so that they substantially abut each other when the conduit has passed the slot. This ensures that the realized through the slot opening is at least substantially closed and the line is securely received in the body.

Under a line is an electrical conductor for transmitting a signal, in particular a BPL signal to understand, having an insulating sheath. A single-core cable comprises only a single conductor. A multicore cable is formed by at least two mutually insulated, combined conductors.

Advantageously, the lines run within the body substantially parallel to each other. This ensures that the wave impedance of the lines is minimized, so that the attenuation of the signal to be transmitted is reduced. In particular, it is advantageous if the lines run with the least possible distance from each other.

In a further advantageous manner, the base body has an elongated shape. The main body may for example be substantially straight. Furthermore, it is conceivable that the geometry of the base body is adapted to the installation situation, the base body is formed bent, for example. It is essential that the lines within the body in a defined orientation - preferably parallel to each other.

To realize a particularly simple construction, it is conceivable that the base body is designed as a tube, wherein the tube does not necessarily have to have a round cross-section. The tube may for example consist of a non-conductive material, in particular polyvinyl chloride (PVC). As a result of the slit extending in the longitudinal direction, the lines can be introduced into the tube, with at least one of the lines being able to be introduced into the tube and / or expelled from the tube by the slide movable along the tube.

In a particularly advantageous manner, two slots are formed on the base body. The slots can for example be realized on opposite sides of the base body, so that the electrical lines in each case by its own, separate slot in the body can be introduced and removed from this. It is conceivable that run in the main body two separate cavities, each one of the slots realized a passage to one of the cavities. As a result, the conductors can be accommodated in cavities of the main body which are separated from each other.

It should be noted at this point that the term cavity in relation to the device according to the invention is to be understood in the broadest sense, namely that it is only necessary that one or more lines can be arranged within the main body. In particular, the main body may be made of an elastic material and be substantially solid or be filled with an elastic material, so that the required cavity is created by the introduction of the line.

To realize the simplest possible construction of the slide, it can enclose the base body at least partially - in the circumferential direction. As a result, the slider is securely arranged on the base body and movable along the longitudinal direction of the base body. In a particularly simple embodiment, the slider may be a ring which is slid over the base body. Depending on which side of the ring is arranged opposite the line, the line can be pushed into the main body or pulled out of it by moving the ring. The arrangement of two rings as a slide, the line can be introduced by means of a ring in the body and discharged by means of the second ring from the body. It should be noted at this point that the slide must not necessarily be designed as a closed ring. It is sufficient if the slider partially encloses the base body in the circumferential direction, so that the slider is fixedly and longitudinally movably connected to the base body. Any positive and / or non-positive connection between the body and slide is conceivable that move a allows the slider in the longitudinal direction of the body.

In a particularly advantageous manner, it is conceivable that the slider is fixable to the base body at least in a defined position, for example can be clamped or latched, so that a movement in the longitudinal direction is prevented. Thus, the position is defined for at least one of the lines in which it penetrates into the main body and exits from this.

Advantageously, the slider may have at least one passage through which the conduit is passed. As a result, the line is pulled out during a movement of the slider from the body or introduced into this, depending on the direction of movement of the slider. Furthermore, it is conceivable that the slide has a plurality of passages, corresponding to the number of electrical lines, so that each of the lines can be passed through a separate passage. According to another embodiment, a plurality of conduits may be passed through a single passage.

As a further protective measure to avoid accidents, it is conceivable that the slider is made of a non-conductive or poorly conductive material. This may be a plastic, for example polyvinyl chloride. Alternatively or additionally, it is conceivable that the base body is at least partially filled with an insulating material, in particular polyvinyl chloride. By the insulating material, the lines are again isolated and it is also possible to lead the lines more accurately, namely due to the reduced cavity within the body. It is further conceivable that in the insulating material at least in the region of a extending in the longitudinal direction of the base body slot is formed. Through the slot a line is feasible and thus introduced into the body.

The underlying object is further solved by claim 12. Thus, a connection material for data transmission, in particular for the transmission of a broadband powerline signal via a power supply network, indicated with a first section consisting of a multi-core, in particular three-wire, line, a second section consisting of two separate, in particular single-core, lines and a Device according to one of claims 1 to 11, wherein the first portion and the second portion are connected to each other and wherein the lines of the second portion are at least partially guided in the main body of the device.

In accordance with the invention, it has been recognized that the arrangement of a device according to the invention in a connection material for data transmission, the attenuation of the signal to be transmitted can be significantly minimized. This is achieved by the guidance of the electrical lines in a defined, in particular small, distance to each other, whereby the wave impedance of the lines decreases. Another advantage is that the risk of accidents for the user of the connection material is considerably minimized.

Advantageously, at the free end of the multicore cable of the first section, a connecting element may be formed for connection to an electrical device. This may be, for example, a connector that is designed to connect to a broadband powerline modem. Alternatively or additionally, at least one of the free ends of the lines of the second portion, a connection element for connecting to a connection means of an electrical system, in particular a low-voltage heavy load bar, be formed.
