Description

Technical Field

[0001] The invention relates to a holding device for fastening an electrical connection device in or near an opening of a wall section. The invention also relates to an arrangement having such a holding device and an electrical connection device fastened thereto. The electrical connection device can be, for example, a plug connector and / or a terminal block. Background Art

[0002] Electrical and electronic components usually have an electrical connection device extending from a housing wall, with which the connection of electrical lines to the component is simplified. The connection device can then be inserted into an opening in a wall section and there fastened to the surrounding housing wall, for example by screwing. It is also known to fasten such a connection device in an opening in a wall section by means of elastic fastening latch arms, for example in a snap-in manner, as described, for example, in DE 10 2010 045 913 B4. Summary of the invention

[0003] The invention is based on the object of specifying an advantageous alternative for fastening an electrical connecting device in or close to an opening in a wall section.

[0004] The object is achieved by a holding device for fastening an electrical connection device in an opening of a wall segment or near the opening, the holding device having at least two holding tabs bent out of the material of the wall segment at the inner edge of the opening, a receiving space for accommodating the electrical connection device to be fastened being formed between the holding tabs, wherein the holding tabs each have at least one fastening profile, the fastening profile being configured to be coupled with at least one fastening element of the electrical connection device, wherein the holding tab is configured to accommodate the electrical connection device in the receiving space and to fix the electrical connection device by means of the fastening profile of the holding tab. Here, the holding tab can be formed in one piece from the material of the wall segment. The material to be separated for producing the opening in the wall segment can advantageously be used directly to provide the holding tab. In this way, the material waste that occurs can be reduced.

[0005] It is also advantageous that the reduced installation space in the opening of the wall segment can be used to fasten the electrical connection device. The holding device can be implemented in particular without separate installation components such as screws or the like. The installation can be carried out very simply using one or a few handles. The installation effort and the costs associated therewith are thereby reduced. By means of such an installation, the required installation space of the plug connector required for installation on the wall segment can be reduced.

[0006] The wall section can be a part of a housing wall of a housing of the electrical or electronic component.

[0007] According to an advantageous design of the present invention, it is proposed that the holding tabs are bent out at least from two inner edges of the opening which are opposite to each other. In this way, the electrical connection device can be particularly reliably accommodated between the holding tabs and fixed thereon.

[0008] According to an advantageous design of the present invention, the retaining tabs are bent out from the wall section substantially in the same direction. The retaining tabs can, for example, respectively face the interior space of the housing surrounding the wall section of the device. The retaining tabs can, for example, be oriented substantially parallel to each other.

[0009] According to an advantageous design of the invention, the wall section is provided with a retaining tab made of sheet metal bent out from the wall section. This allows the electrical connection device to be reliably fixed to the wall section. The retaining device can also be manufactured in a simple manner, for example by means of a stamping and bending process.

[0010] According to an advantageous embodiment of the invention, one, more or all of the retaining tabs have an inner opening as a fastening contour, into which the fastening element of the electrical connection device, which is designed as a projection, can be inserted in a form-fitting manner. In this way, the electrical connection device can be simply and quickly fastened to the retaining tab and can be unfastened from it again without accident. The electrical connection device can, for example, be latched in the inner opening of the retaining tab. The inner opening can here be completely or only partially surrounded by the material of the retaining tab on the circumferential side.

[0011] According to an advantageous embodiment of the invention, the retaining web is spring-elastically deflectable, ie it springs back toward the relaxed position during deflection.

[0012] Furthermore, the electrical connecting device can also be removed from the holding device in a simple manner, for example by pressing the holding tabs away from one another.

[0013] The object mentioned at the outset is also achieved by an arrangement having a holding device of the type described above and an electrical connecting device fastened to a fastening contour in a receiving space between holding tabs. The advantages described above are also achieved thereby.

[0014] The coupling between the fastening contour of the retaining web and the associated fastening element of the electrical connection device can be realized by force fit and / or form fit.

[0015] According to an advantageous design of the present invention, the retaining tab is spring-elastically pressed against the electrical connection device with pretensioning. In this way, a certain spring-elastic retaining force can be applied to the housing of the electrical connection device by the fastening tab.

[0016] The electrical connection device can be fastened directly on the holding tab or fastened on the holding tab by means of a connection adapter. When a connection adapter is used, it is considered as part of the electrical connection device within the scope of the present application.

[0017] In another aspect, the invention comprises a method for fastening an electrical connection device in or near an opening of a wall segment, the method having the following steps:

[0018] a) bending out at least two retaining tabs at the inner edge of the opening of the wall segment and producing at least one fastening contour on each retaining tab,

[0019] b) The electrical connection device is fastened in the receiving space formed between the holding webs by means of the fastening contours of the holding webs.

[0020] The above-mentioned advantages can also be achieved thereby. The retaining tab and / or its fastening contour can be produced, for example, by means of a punching and bending process. Advantageously, the retaining tab can be formed in one piece from the material of the wall segment, minimizing material waste.

[0021] In an advantageous embodiment, the fastening contour can be produced before the retaining tabs are bent out, thereby simplifying the punching process.

[0022] In an advantageous embodiment, the electrical connection device can be fastened to the holding tab only from one side, for example from the outer side of the housing with the wall section, or from the inner side of the housing. In an advantageous embodiment, the electrical connection device can be fastened to the holding tab selectively, that is to say at the option of the user, from the inner side or from the outer side.

[0023] In the sense of the present invention, the indefinite article "a" is not to be understood as a numeral. Thus, when, for example, a component is mentioned, this should be interpreted in the sense of "at least one component". If an angle is specified in degrees, it relates to the circle size of 360 degrees (360°). BRIEF DESCRIPTION OF THE DRAWINGS
