In an industrial environment, communication devices such as telephones, controllers and / or computers are interconnected via one or more communication networks. Such an industrial environment consists, for example, in control stations for excavators, cranes, transfer stations or the like. To connect the telephones, controls and / or computers connection boxes are used, such as hubs, routers and gateways to which several communication devices are connected via cable connections and interconnected. However, the vibration load in industrial environment is often very large, so that there is an increased risk that solve the cable connections.

The object of the invention is to provide an electronic assembly, in particular a Reihenklemmanordnung, with such a junction box, in which the cable connection of a cable is ensured to the junction box. What is provided is a molded part for fastening at least one cable, wherein the molded part can either be attached to a connecting rail and / or a row terminating terminal of an electronic assembly, in particular a modular terminal arrangement, or attached to a terminal block in the form of a terminal box or molded or attachable or formable, and wherein the molded part has at least one holding means to which the cable can be fastened.

Preferably, the molding has a plurality of retaining grooves into which the same cable can be inserted, which gives the cable attachment additional support and the transmission of vibrations via the cable to a junction box particularly clearly reduces.

If the cable can be clamped in the retaining groove, no additional fastening means are required for securing the cable.

In a preferred embodiment, the molded part comprises a holding element, to which the cable can be releasably fastened by means of a fastening means. The retaining element is preferably designed in the shape of a peg and makes it possible to fix the cable joined into the retaining groove by means of the fastening means, for example by means of a cable tie, band or wire. In this embodiment, even very thin cables which can not be clamped in the retaining groove can be securely fixed by means of the fastening means on the retaining element. It is further preferred that the molded part has a plurality of retaining grooves and a plurality of retaining elements, which are provided for fastening a plurality of cables. It is preferred that a retaining element is provided for each retaining groove, or that at least for one of a plurality of retaining grooves, which are provided for the same cable, a retaining element for fastening the cable by means of the fastening means is hen provided. As a result, a variety of cables on the molding are securely fastened.

For joining the molded part to the connecting rail, the molded part preferably has joining means. Such joining means are, for example, latching means for latching and / or sliding grooves for pushing the molded part onto the connecting rail, with which the molded part can be attached to the connecting rail in a displaceable or non-displaceable manner. The molded part can therefore not be detached from the connecting rail even with heavy vibration load.

Additionally or alternatively, the molded part has joining means for joining the molded part to the connection box. Preferably, the joining means is a bore, so that the molded part can be joined to the connection box with a screw or rivet. In principle, a cohesive joining, for example by gluing, possible.
