Description

The invention relates to a line marking system for detachable via a releasable connection line having a first line end and a second line end, wherein the releasable connection with its two line ends has matching fasteners.

In maintenance and repair activities on pipelined installations, it is known to apply markings in the form of adhesive strips to line connections to be cut in order to be able to connect the respectively correct lines to one another later after the reconstruction. Such a self-adhesive cable marking strip for electrical lines is from the DE 10 2011 054 505 A1 known. Similar cable marking systems work, for example, with a label printing device, the label then has to be glued to the cable to be marked. The disadvantage is that the labels are usually only one color and especially only freely accessible cable strands can be marked. So is a contact of a plug that is, for example, directly to a power consumer, not or only very bad markable. Furthermore, there is always the risk that the labels peel off, because the adhesive ages, due to dirt no longer sticks or dissolves due to cold. Furthermore, stickers on body parts that are protected, for example, with wax against corrosion do not hold. Ideally, the substrate for these self-adhesive cable marking strips would have to be free of dust and grease, which is usually impossible in reality.

The term "management" is used in various technical disciplines, e.g. B. in electrical engineering for electrical signal and power lines or in plant construction for fluid-carrying pipelines, especially in heating construction for pipelines that transport liquids or gases. Thus, the term "line" in the context of the subject of the application for all the above disciplines interpreted, even if in the embodiments primarily electrical lines (cables) are described.

In further development of any adhesive tape labeling marking systems for cables and wires in various configurations, the line clamping surrounding, threaded or the like are also known. For example, according to a marking system for cables and wires according to DE 33 00 908 A1 referenced, in which color-coded and / or labeled tabs are attached to the line. From the EP 0 366 873 B1 is a C-shaped, to be fixed to cables carrier for marking purposes consisting of a sleeve having a longitudinal slot, is known in which a special design threading of the carrier on the line is facilitated. WO 2014/173 926 A1 describes a conductor marker which clamps on the line to be marked and locks the line so that this marking on the line can not slip. The utility model DE 20 2015 002 706 U1 describes a marking carrier for the identification of electrical conductors, equipment or facilities that can be mounted on the line and, for example. Has a three-digit numbering with individually plugged digits.

The EP 1 622 172 A1 shows a wire harness and a harness manufacturing method in which individual lines are provided with markings, so that the assignment of the free end of the line can be assigned for insertion into a connector. Thus, the production of wire harnesses is facilitated.

In the DE 102 24 713 A1 it is flat cable, a method for repairing the flat cable and an apparatus for performing the method in which removes a damaged area of a flat cable and receives a new flat cable with corresponding exposed contact points each associated with this contact.

The DE 297 21 028 U1 describes an arrangement of cable segments or pieces of cable which are detachably connected to each other in a chain-like manner. This is to facilitate the assembly of wiring according to a wiring plan for the fitter.

In the US 2002/0 144 381 A1 a well-known crocodile clip is described by way of example.

US 2014/0 259 567 A1 describes the connection of printhead connections for marking rods, for example the control rod of a scooter.

US 2009/0 241 384 A1 describes generally known marking labels for electrical cables.

The generic US 2011/0 086 540 A1 describes a cable connection marking set consisting of dummy elements belonging to corresponding connectors, such as the known "RCA" connectors, as are common in home entertainment systems. The dummy plugs or sockets have marking flags with assignable markings, so that a unambiguous assignment of the respective plug to the respective sleeve is provided.

A very similar system shows the US 2006/0 009 068 A1 from which also connectors with connectors and associated sockets for audio and video cables are provided with corresponding dummy plugs with marking option.

A similar system is also from the US Pat. No. 6,997,738 B1 It is known to provide cable identification plugs for electronic devices which also have dummy plug pairs which can be associated with each other.

Thus, for electrical connectors line marking systems are known, which allow an assignment of a male end with another socket end. For other electrical connections, however, there are no suitable means for unambiguous assignment. Furthermore, it is known to provide the insulation of cables with a color code, so that the assignment via the color code is possible.

A problem in particular in older electrical systems, such as in older vehicles, aircraft or boats that any previous color code of the cable is no longer recognizable, is no longer respected by intermittent (improper) installations or was never present. On the other hand, markings provided with adhesive strips become unintentionally detached or dirty, so that they become unusable. It is correspondingly difficult to assign detached cables.

A disadvantage of these marking systems is that, although the respective line is marked with a color / character code, but this can only be done at discrete locations along the line. If a line is thereby disconnected from connecting elements (for example a plug / socket combination), there are two free ends of this line, at which possibly only at remote locations a corresponding cable marking is visible for later unambiguous assignment of these two lines to be reconnected. Accordingly, the assignment is difficult and expensive.

The object of the invention is therefore to provide a marking system that makes the assignment of screw holes connected to threaded sections lines that had to be separated after disassembly of components, beyond doubt and safe after re-installation of the corresponding components possible.

This object is achieved with a line marking system according to claim 1.

By virtue of the fact that the two mating connection elements are a threaded section with nut and screw lug, dummy element pairs which can typically be used for the line marking system are predetermined. In this case, the respective dummy elements are formed so that they can be applied to a threaded portion with nut or Schraublasche. It is important that the respective dummy elements are firmly connected to the respective connecting element.

If the matching mark is a color code, a graphic mark, a number and / or letter (s) or any other distinctive distinctive coding, an easily identifiable and unique mark is provided so that during repair / maintenance work, the removal of equipment elements required line separations after maintenance and installation of the system part can be assigned safely even in adverse environments. Combinations of the abovementioned codes can also be used as a mixture of color code and letter / number designation.

If the mark is attached to the respective dummy element interchangeable via a push-button connection, the markings can be adapted to the respectively used dummy element pairs to the respective application.

Preferably, the dummy element is produced as a plastic injection molded part. In particular, in electrical systems and thus electrical lines and corresponding electrical couplings, an embodiment of the dummy element made of plastic is preferred because the corresponding parts are electrically non-conductive. In addition, plastic injection molded parts can be produced inexpensively in large quantities.

Many maintenance and repairs to plants are possible without a circuit diagram and with considerable time savings. In the separation of a line, only the line ends corresponding to the separate connection point with a suitable dummy element are marked on both sides consistently, this work is performed sequentially for each line until the corresponding component can be removed, repaired and reinstalled. Then, without knowledge of a circuit diagram, the corresponding line ends can be reconnected according to the matching markings, whereby a reliable restoration of the original state is achieved.

Hereinafter, an embodiment of the wire marking system will be described in detail with reference to the accompanying drawings.
