The present invention relates to an electrical construction element comprising a housing and a plane-defining assembly plate projecting from the housing, in which at least one assembly hole is machined for mounting a connecting member having an enlarged head, characterized in that the at least one assembly hole comprises at least one assembly hole provided with a flat settling portion for use with a connecting member having a cylindrical head or at least a flat bearing surface.

Preferably, the electrical component is a mounting plug connector.

Preferably, the connecting member is a screw or a rivet.

Preferably, all the fitting holes are provided with the flat depressed portion.

The utility model has the advantages of: the counter-sunk or round counter-sunk screw can avoid adverse splitting effects, in particular on the connecting region of two sections of the mounting bore having different diameters, which is advantageous in particular in mounting plates or components made of brittle materials.

Preferably, the at least one mounting opening with the flat depression comprises at least one open mounting opening which is arranged in an edge region of the mounting plate and the longitudinal section of which opens out over a section of the circumference of the mounting opening for receiving the head of the connecting element. Thus, the splitting action can also be further reduced, in particular when the head of the connecting member fits into the fitting hole with little or no play and/or even with slight eccentricity.

A preferred embodiment provides that the longitudinal section of the open mounting opening, for receiving the head of the connecting element, opens out over at most half of the circumference of the mounting opening, preferably over a section between 20% and 40% of the circumference.

A further embodiment of the invention is characterized in that the mounting plate has a smaller surface extension at a first thickness corresponding to a longitudinal section of the mounting hole for receiving the head of the connecting element than at a second, subsequent thickness of the mounting plate, which projects in a flange-like manner beyond the first thickness of the mounting plate at least in the region of the mounting hole.

In particular, it is advantageous to implement the mounting plate in one piece with the housing of the construction element for the purpose of stabilizing the construction element and its connection to the instrument housing or the like.

A further advantageous embodiment of the invention is characterized in that the inner wall of the longitudinal section of the mounting bore with the flat depression is designed cylindrically and coaxially to the rest of the mounting bore and also coaxially to the head of the connecting element for receiving the head of the connecting element. Thus, the accessibility, the mechanical stability and the protection against damage of all components are combined as good as possible.

Preferably, the construction element is designed as a mounting plug connector for connection to a cable plug connector for transmitting energy, data or media.

Detailed Description

It is first of all to be understood that identical components in the different described embodiments are provided with the same reference numerals or the same component names, wherein the disclosure contained in the entire description may be transferred to identical components having the same reference numerals or the same component names in a meaningful manner. The positional references selected in the description, such as upper, lower, lateral, etc., relate to the figures described directly and shown and should be transferred to the new position in the sense of a change in position.

Fig. 1 shows a first embodiment of an electrical component according to the invention in the form of a mounting plug connector, typically also referred to as a socket of a plug connector, for coupling with a cable plug connector K (see for this purpose the schematic representation of fig. 2) or a plug for transmitting energy, data or media. The mounting plug connector comprises a housing 1 and a mounting plate 2 which projects radially from the housing and defines a plane. The mounting plate 2 is preferably flat in itself and, in the embodiment shown, is fitted from the outside, for example, onto the housing G of the device to which the plug connector is to be attached, in order to transfer electrical energy and/or electrical signals, and optionally also optical signals, from or into the device. If necessary, the plug connector constructed according to the invention can also be used in connectors for various media.

The mounting plate 2 is preferably formed integrally with the housing 1, from which an optionally formed electrical connection 1a for current, electrical signals or liquid or gaseous media is led back and/or to the side. The housing 1 can be made of plastic or be produced as a metal housing, advantageously for circuit board assembly, wherein the metal housing and the ground contact are protected against high frequencies. There is also the possibility of mounting from the rear side onto the housing wall G, for which purpose the subsequently described embodiment according to the invention is arranged on the side of the mounting plate 2 opposite the drawing (i.e. on the rear side of the mounting plate 2, which is not visible in the drawing). In a mounting opening 3 formed in the mounting plate 2, a connecting element 4 comprising a widened head 5 can be mounted, with which a plug connector or socket can be fixedly fastened to the instrument housing G or a similar wall. The connecting member 4 is preferably constructed as a screw or rivet comprising a cylindrical head. The head 5 of the connecting element is thereby transferred by an annular surface 8 (see fig. 4 for this purpose) oriented perpendicularly to the longitudinal axis of the connecting element 4, i.e., the "chin", into a shaft 9 of the connecting element 4, which has a smaller diameter than the cylindrical head 5. In the embodiment of the connecting member 4 as a cylindrical head screw comprising a socket head or as a slotted or cross-slotted screw, the shaft 9 is provided with an external thread.

In cooperation with this, the fitting hole 3 is provided with a flat depression for use with the connecting member 4 including a cylindrical head. This means that the section of the mounting opening 3 which receives the head 5 of the connecting element 4 transitions via the annular bearing surface 6 for the annular surface 8 of the connecting element 4, which is preferably parallel to the plane of the mounting plate 2, into the section of the mounting opening 3 which receives the shaft of the connecting element 4 and has a smaller diameter than the section for the head 5.

The embodiment of the construction element according to the invention shown in the figures is preferred, in which the mounting holes 3 are provided in the edge region of the mounting plate 2. In this case, a longitudinal section of the mounting opening 3 is open to the outside, i.e. has a recess 7, over a section of its circumference for receiving the head 5 of the connecting element 4. The recess 7 extends over at most half the circumference of the mounting opening 3. Particularly advantageous is a variant in which the upper section of the mounting bore 3 for the head 5 of the connecting element 4 is open between 20% and 40% of the circumference. In the remaining circumferential region of the head 5 of the connecting element 4, said head is surrounded with little play by the inner wall 10 of the upper section of the assembly opening 3. The inner wall 10 of the longitudinal section of the assembly opening 3 is preferably cylindrical for receiving the head 5 of the connecting element 4, as is the head 5 of the connecting element 4 itself, and surrounds it with little play. The longitudinal axis of the cylindrical inner wall is preferably also coaxial in its entirety with the axis of the assembly opening 3.

The mounting plate 2 can have a smaller surface extension at a first thickness, which corresponds to the longitudinal section of the mounting opening 3 for receiving the head 5 of the connecting element 4, than at an immediately subsequent second thickness of the mounting plate 2, which projects in a flange-like manner beyond the first thickness of the mounting plate 2 at least in the region of the mounting opening 3.

Fig. 3 shows an embodiment of a plug connector as an example for an electrical component according to the invention comprising four assembly openings 3. A slotted screw inserted into one of the mounting openings 3 is shown here by way of example as a connecting element 4. The head 5 of the slotted screw is also enlarged with respect to the diameter of the section through the mounting hole 3 and with respect to the diameter of the mounting hole 3 itself. As for all connecting elements 4 according to the invention, the head 5 is also equipped with an annular bearing surface 8 oriented perpendicularly to the longitudinal axis of the connecting element 4, which merges into the shaft 9 of the connecting element.

The central region of the mounting plug connector, which is designed to receive the corresponding plug K, is defined in the illustrated preferred embodiment of the invention by an annular projecting web 2a and has a pin 2b in the center, on the outer peripheral wall of which an electrical contact 2c leads out or is mounted. Fig. 3 and 4 show this structure and others described next in detail. The socket-shaped section of the plug K, which comprises the corresponding mating contact, can be pushed into an annular gap 2d, which gap 2d surrounds the central pin 2 b. Finally, the central pin 2b is also hollow and can have further electrical contacts 2f in its interior 2e or on its interior. The groove 2g in the annular web can receive a projecting pin or a short web extending in the longitudinal axial direction of the plug K, which is part of the latching system in order to prevent unintentional disengagement of the plug connection.

The embodiment of the plug connector to be mounted, which is illustrated here in the drawing, shows a rectangular, preferably square, mounting plate 2, which preferably surrounds its own socket or housing 1, such as a closed flange. Of course, other polygonal or round shapes can also be used, as can only a tongue-shaped mounting lug which projects radially outward from the housing 1 and on which a mounting opening 3 constructed according to the invention is formed. The number of assembly openings 3 can also be selected in principle, wherein preferably at least two opposing assembly openings 3 are provided with a recess 7 facing the outside of the assembly plate 2, as shown in the figures. Preferably, all the fitting holes 3 present are provided with a clearance 7.

The specific shape and design of the actual plug connector region is also to be regarded in the illustrated embodiment as only one of many possible examples and is therefore not limited to the illustrated shape with a central hollow pin 2 b. These examples show possible embodiment variants, wherein it is to be noted here that the invention is not limited to the specifically shown embodiment variants, but also encompasses variants within the capability of the person skilled in the art.
