Description

Identification strips, labeling system and method The present invention relates to an identification strip for an electrical installation, with a labeling area that is designed for printing with a printing device, with a clamping area that is designed to engage in a fastening groove, the labeling area and the clamping area being a first plastic exhibit. The invention also relates to an inscription system with an identification strip and a method for producing an identification strip.

Identification strips for electrical installations are used e.g. to identify the assignment of terminals or to designate components.

For attachment to an object to be marked, the marking strips can be clamped into a groove provided for receiving the marking strip and latched there. It is important that the marking strip remains in its position in the fully assembled state in order to ensure permanent assignment of the designated terminals, connections or objects.

Known identification strips have the disadvantage that they lead to slipping within the receiving or

Tilt the fastening groove. For example, due to environmental influences, vibrations or improper maintenance of the electrical installation labeled with the aid of the identification strip, the identification strip may slip within a receiving groove or completely fall out of a receiving groove or BE2019 / 5135 is driven out. Against this background, the invention is based on the technical problem of specifying an identification strip for an electrical installation that does not have the disadvantages described above or at least to a lesser extent, and in particular enables reliable fastening to an associated fastening groove. Furthermore, a labeling system with such an identification strip and a method for producing an identification strip are to be specified. The technical problem described above is solved in each case by a marking strip according to claim 1, a labeling system according to claim 11 and a method according to claim 12. Further embodiments of the invention emerge from the dependent claims and the description below.

According to a first aspect, the invention relates to an identification strip for an electrical installation, with a labeling area that is set up for printing with a printing device, with a clamping area that is set up to engage in a fastening groove, the labeling area and the clamping area having a first plastic. The inscription area and / or the clamping area have at least one adhesive area which has a second plastic, the second plastic being softer than the first plastic in order to increase the static friction. The adhesive area therefore forms a slip protection or serves to prevent slipping, provided the identification strip is in an assigned fastening groove of a fastening object or

Fastening body is added. In this way it can be ensured that the identification strip reliably remains in its originally intended mounting position and does not slip or be driven out of the groove due to vibrations or the like. When it is mentioned in the present case that the second plastic is softer than the first plastic, this means in particular that the second plastic has a lower Shore hardness than the first plastic. The first plastic can e.g. be a thermoplastic, such as a polyamide PA66, PA6, PA66 / 6, PA6 / 66, PA 4.6, PA10, PA12, PA6.10, polycarbonate, polybutylene terephthalate (PBT), polycarbonate / polybutylene terephthalate (PBT / PC), polyethylene terephthalate (PET) , Acrylonitrile-butadiene-styrene copolymer (ABS), polycarbonate / acrylonitrile butadiene styrene (PC / ABS), polycarbonate / acrylonitrile-styrene-acrylate copolymer (PC / ASA), polyvinyl chloride (PVC), polypropylene (PP), polyethylene ( PE) or the like. The first plastic can e.g. be a thermosetting plastic, such as epoxy resin (EP resin), polyester resin (UP resin), phenolic resin (PF resin), melamine resin (MF resin), melamine / phenolic resin (MP resin), urea resin (UF resin) or the like .

The second plastic can e.g. be a thermoplastic elastomer such as thermoplastic polyurethane (TPU), thermoplastic copolyester (TPEE), styrene-ethylene-butylene-styrene (SEBS), styrene-butadiene-styrene (SBS), polyether block amide (PEBA) or the like, or a cross-linked elastomer such as polypropylene / ethylene-propylene-diene rubber (PP / EPDM), chloroprene rubber (CR), butadiene rubber (BR) or the like.

The first plastic can e.g. a polyamide (PA) with a hardness greater than Shore D 35, while the second plastic is a styrene-ethylene-butylene-styrene (SEBS) with a hardness less than Shore D 35.

The first plastic can e.g. a polyamide (PA) with a hardness greater than Shore D 54, while the second plastic is a thermoplastic polyurethane (TPU) with a hardness less than Shore D 54.

The first plastic can e.g. a polycarbonate (PC) with a hardness greater than Shore D 35, while the second plastic is a styrene-ethylene-butylene-styrene (SEBS) with a hardness less than Shore D 35.

The first plastic can e.g. a polycarbonate (PC) with a hardness greater than Shore D 54, while the second plastic is a thermoplastic polyurethane (TPU) with a hardness less than Shore D 54.

The first plastic can e.g. a polycarbonate / acrylonitrile butadiene styrene (PC / ABS) with a hardness greater than Shore D 35, while the second plastic is a styrene-ethylene-butylene-styrene (SEBS) with a hardness less than Shore D 35.

The first plastic can e.g. a polycarbonate / acrylonitrile butadiene styrene (PC / ABS) with a hardness greater than Shore D 54, while the second plastic is a thermoplastic polyurethane (TPU) with a hardness less than Shore D 54.

It can be provided that the identification strip is provided as an endless material by co-extrusion of the first and the second plastic. Accordingly, the identification strip can, for example, be made available rolled up on a roll and fed to a corresponding printer. The identification strip can in particular be set up for printing using a BE2019 / 5135 thermal transfer printer, an inkjet printer, a laser printer or the like.

According to a further embodiment of the marking strip, it is provided that the labeling area has a first side with a cover surface to be printed, an adhesive area of the labeling area being formed on a second side facing away from the first side and / or an end face of the labeling area. A reliable fastening of the identification strip can thus be achieved without restricting the available area for printing symbols or characters.

In particular, it can be provided that the adhesive area of the inscription area is set up, in the fully assembled state, to lie against a fastening object or fastening body in which a fastening groove is formed, or to be latched onto it, so that the adhesive area is attached to a surface of the fastening object or fastening element. Fastening body is applied.

According to a further embodiment of the identification strip, it is provided that the inscription area has at least two or exactly two adhesive areas. In order to achieve reliable positioning of the identification strip, the labeling area can be provided with an adhesive area, in particular on both sides, in order to reduce the static friction in the fully assembled state with respect to a fastening object or

Fastening body on which the identification strip is held to increase.

It can be provided that the inscription area has an inscription surface to be printed, the

The writing surface has the first plastic and has no area made of second plastic. It can be provided that the inscription surface consists of the first plastic.

The clamping area can have at least two or exactly two protruding webs, with at least one of the webs having an adhesion area. The webs serve in particular to engage in undercuts of the fastening groove in order, on the one hand, to establish a form-fitting connection and, in particular, also to allow the labeling area and the clamping area to be braced relative to the groove. In the manner described above, the adhesive area is used to increase the static friction of the marking strip in the fully assembled state with respect to a contact surface on which the adhesive area rests. It can be provided that a corresponding adhesive area is formed on each of the webs.

It can be provided that the adhesive area of the web is arranged facing the inscription area. This makes it easier to assemble the identification strip when it is inserted into the groove, since the described arrangement of the adhesive area avoids contact of the adhesive area with lateral boundary surfaces when it is inserted into the groove, so that the adhesive area is only clamped against a contact surface in the fully assembled state within the groove .

The webs of the clamping area can be formed in one piece with the inscription area, in particular in the context of a described co-extrusion, and, viewed in a cross section, starting from the inscription area, extend in a substantially V-shape diverging. In the present case, diverging in a substantially V-shape does not mean that the webs converge in a common point of the inscription area, but that the webs, starting from the inscription area, move away from one another in a funnel-shaped widening. The webs are in particular arranged at a distance from one another on the inscription area. Alternatively or in addition, the webs each have an end section which is formed at least in sections parallel to a width of the inscription area.

In this case, the width extension of the inscription area, viewed in a cross section, is oriented transversely to the longitudinal extension of the identification strip. The webs formed in sections parallel to a widthwise extension of the inscription area enable the webs to engage in an undercut of a groove in order to form a positive connection to a groove.

In order to enable simple and inexpensive production of the identification strip, the identification strip can alternatively or additionally be designed with mirror symmetry when viewed in a cross section. In this way, feeding to a printing device can also be facilitated.

According to a further embodiment of the identification strip, it is provided that the adhesive area is arranged on a freely protruding end section of the web. In particular, the adhesive area can accordingly be formed in an area which, in the fully assembled state, is resiliently tensioned against a surface of the fastening groove in order to ensure that the adhesive area rests against a contact surface of the fastening object to which the identification strip is fastened.

According to a further embodiment of the identification strip, it is provided that the labeling area has two adhesive areas and the clamping area has two adhesive areas, the adhesive areas of the labeling area being at a greater distance from one another than the adhesive areas of the clamping area. In this way, a reliable positioning of the identification strip can be ensured under different load cases.

Alternatively or in addition, it can be provided that an adhesive area of the inscription area is arranged facing an adhesive area of the clamping area. If, for example, the labeling area and the clamping area are clamped in the fully assembled state with their respective adhesive areas against a respectively assigned contact or abutment surface of a fastening groove or the labeling body having the groove, it can be ensured that each adhesive area rests reliably on a contact area in order to to increase the static friction in the fully assembled state.

In order to enable simple and cost-effective production of the identification strip, it can be provided that the adhesive area consists of the second plastic and / or all areas of the identification strip that differ from the adhesive area consist of the first plastic. According to a further variant of the identification strip, it is provided that the adhesive area has a shoulder or a step in order to achieve a defined contact with a fastening body in a fully assembled state. According to a second aspect, the invention relates to a labeling system for an electrical installation, with a labeling strip according to the invention and with a

Fastening body which has a fastening groove, the clamping area of the identification strip engaging in the fastening groove.

In particular, it can be provided that the clamping area of the identification strip has webs which engage in an undercut of the fastening groove.

It can be provided that the inscription area rests on a wall of the fastening body that delimits the groove.

In particular, it can be provided that the identification strip is clamped or latched onto the fastening body, the clamping area in particular with cantilevered webs resting against an undercut of the fastening groove and the labeling area resting with a side facing away from the top surface of the labeling area on a side wall of the fastening body delimiting the fastening groove so that the identification strip is resiliently tensioned or latched on the fastening body in a resilient manner. In particular, each area, i.e. both the clamping area and the labeling area, has one or more adhesive areas that rest on an associated contact surface of the fastening body in order to increase the static friction and to prevent or counteract displacement of the marking strip within the fastening groove .

In order to provide the largest possible inscription area, it can be provided that the inscription area has a width which is the total width of the

Fastening body exceeds and the fastening body BE2019 / 5135 in particular protrudes on two sides. According to a third aspect, the invention relates to a method for producing an identification strip for an electrical installation, wherein the identification strip is designed in the manner according to the invention, with the method steps: plasticizing the first and second plastic, co-extruding the first and second plastic in such a way that the Adhesive area is a strand connected to the other areas of the inscription area and / or the clamping area in a materially and / or positively locking manner.

In this way, the identification strip can be provided in a simple and cost-effective manner as an endless material in the co-extrusion process. In particular, the identification strip has four adhesive areas, each of which is formed as a strand connected to the clamping area and the labeling area in a materially bonded manner. In particular, as a result of the production in the co-extrusion process, the identification strip has a constant cross section, viewed along its longitudinal extension, which corresponds to the extrusion direction.

As an alternative to co-extrusion, continuous injection molding or two-component injection molding or extrusion can be used to produce the identification strip. As an alternative or in addition, the first and second components can initially be provided separately, in particular extruded, and then connected to one another.
