Abstract

A switch cabinet includes an electric component, e.g. a power converter, having at least three cable connection elements. Each of the cable connection elements has an electric contact area capable of being contacted by a cable lug, and an assembly area. The cable connection element is fastenable at the assembly area to a body of the electric component and is connected to the body of the electric component at the assembly area. The electric contact area and the assembly area are arranged on the cable connection element in such a way that a plane of the electric contact area and a plane of the assembly area intersect at a positioning angle.

Description

[0018] The invention is described and explained in more detail below on the basis of the exemplary embodiments shown in the figures, in which:

[0019] FIG. 1 shows a connection from the prior art,

[0020] FIG. 2 shows a cable connection element,

[0021] FIG. 3, FIG. 4 show exemplary embodiments of a cable connection element with inclined electrical contact area, and

[0022] FIG. 5 shows a power converter with inclined cable connection elements.

[0023] FIG. 1 shows an arrangement known from the prior art with a switchgear cabinet 4, in which an electrical component 2 is arranged. This electrical component 2 is supplied with electrical energy via three cables 5. The cables 5 are connected to the electrical component 2 via connection elements. The contact area is oriented in parallel in relation to the area of the electrical component 2, to which the connection elements on the electrical component 2 are attached. As a result, the cables 5 are bent in an S-shape, in order to avoid covering the connection elements of the other cables 5 and simultaneously in order to be able to be guided through the lead-through in the switchgear cabinet 4.

[0024] FIG. 2 shows a cable connection element 1. The cable 5 is fastened to the electrical contact area 11 of the cable connection element 1, for example by means of a cable lug and a screw. The cable connection element 1 is mechanically connected at the assembly area 12 to a body 20. In this context, the plane 110 of the electrical contact area 11 is inclined in relation to the plane 120 of the assembly area 12. This means that the plane 110 of the electrical contact area 11 and the plane 120 of the assembly area 12 intersect in an angle . This angle is also referred to as the positioning angle.

[0025] FIG. 3 shows an exemplary embodiment of a switchgear cabinet 4, in which an electrical component 2 is arranged. Here too, the electrical component 2 is also supplied with electrical energy via three cables 5. However, the electrical connection to the electrical component 2 takes place by means of a cable connection element 1 according to FIG. 2 in each case. In this context, the body 20 represents the electrical component 2 in this exemplary embodiment. Here, the cable connection element 1 has the electrical contact area 11 for connecting to the cable 5, which is inclined in relation to the assembly area 12, at which the cable connection element 1 is fastened to the electrical component 2. Due to this inclination by the angle , the cables 5 can be guided with few bendings on the path from the cable lead-through of the switchgear cabinet 4 to the cable connection element 1. This likewise reduces the mechanical forces transferred from the cable 5 to the cable connection element 1. In this context, the cable lead-through may be arranged at the base of the switchgear cabinet 4, as shown in FIG. 3, or on the top of the switchgear cabinet 4 according to FIG. 4. With regard to FIG. 4, reference is made to the description relating to FIG. 3 and the reference characters therein.

[0026] FIG. 5 shows a power converter 3 as electrical component 2. The electrical terminals are designed as cable connection elements 1, in which the electrical contact area 11 is inclined in relation to the assembly area 12. In this context, the plane 120 of the assembly area 12 is arranged with an offset in relation to the plane 130 of the surface of the electrical component 2 situated in the surrounding area of the electrical contact area 11. This offset arrangement may be arranged offset in parallel here, or may also have an angle in relation to one another. The plane 110 of the electrical contact area 11 and the plane 130 of the surface of the electrical component 2 situated in the surrounding area of the electrical contact area 11 intersect here in a further angle . This makes it possible to guide the cables in a particularly advantageous manner, as due to this further angle it is also possible for the cables to flow in a simple manner, without pronounced bendings in the cables (not shown here), at a desired distance from the surface, in particular from the surface situated in the surrounding area of the electrical contact area 11, of the power converter 3.

[0027] In summary, the invention relates to a cable connection element with an electrical contact area and an assembly area, wherein the electrical contact area can be brought into contact with a cable lug, wherein the cable connection element can be fastened at the assembly area to a body. In order to improve the cable connection element, it is proposed that the electrical contact area and the assembly area are arranged on the cable connection element such that the plane of the electrical contact area and the plane of the assembly area intersect. The invention further relates to an electrical component, in particular a power converter, with a cable connection element of this kind, wherein the cable connection element is connected at the assembly area to the electrical component. The invention further relates to a switchgear cabinet with at least one electrical component of this kind.
