Built-in device and a mounting plate, which enable easy installation. Limitations of previous systems, which are based, for example, on the use of DIN rails on which the electrical built-in devices are mounted, can be overcome. The concept of the design of built-in devices and mounting plates, which deviates from the state of the art, enables

Acceleration and simplification of the assembly of control cabinets. The electrical devices can be easily and automatically mounted on the mounting plate.

Mounting the built-in devices directly on the mounting plate also results in great flexibility in terms of

Positioning of the electrical devices on the mounting plate. Positioning restrictions caused by the use of DIN rails can thus be overcome.

The electrical built-in devices can provide different functionalities from a simple provision or

Distribution of potentials via switching and fuse elements up to powerful control units for carrying out various control tasks, to name just a few exemplary applications.

The mounting plate can in principle be designed as

Base for mounting electrical devices. The mounting plate typically has a flat plate shape so that the electrical devices can be mounted on it in a single plane. It is essential that the mounting plate has a mounting surface for attaching the electrical devices.

The mounting plate is preferably installed in the control cabinet in a fully assembled state with the electrical devices mounted on it. Depending on the type of application, the mounting plate can be made of an electrically conductive material, typically a metallic material such as steel, aluminum or

copper, or made of an insulating material.

The installation of electrical devices on the mounting plate concerns the attachment of electrical devices on the

Mounting plate and, if necessary, one with the attachment of the electrical

The contacting of the mounting plate or mating contact elements attached to the mounting plate is associated with the installation of devices on the mounting plate. Any further connection of the

Mounting plate and/or the electrical devices with conductors that are plugged into terminals, for example, can also be carried out, but is not the core of the ideas presented here for the automated assembly of electrical

Built-in devices on mounting plates.

The fastening devices are used to attach the electrical

Built-in devices on or at the mounting plate. Every electrical

Each built-in device comprises at least one fastening means. Typically, each electrical built-in device comprises several spatially distributed on the housing body

Fasteners for generating a uniform contact force between the respective electrical device and the mounting plate. The fastening means are arranged, for example, on opposite sides of the housing body. Various types of fastening means are known and can, for example, be designed for snap-in or latching mounting in holes or recesses of the mounting plate. Further possible configurations of the fastening means are discussed below.

The housing body of the electrical device can be a body of a housing of the electrical device or, as in the case of a terminal block, its functional body. The relevant physical design of the electrical device is the physical configuration.

The fastening device receptacles correspond in their positions on or at the mounting plate with the fastening devices. The fastening device receptacles are preferably in

Positioned in accordance with the standard dimensions of the electrical devices for mounting the electrical devices. An arrangement in a regular grid, which can be defined, for example, by a hole pattern on the mounting plate, is particularly advantageous. The same applies to the arrangement of contact elements of the electrical devices and mating contact elements on the mounting plate.

In addition, the design of the fastener receptacles corresponds to the fasteners, i.e. the fastener receptacles are adapted to the type of fasteners.

The system comprises the mounting plate and the at least one electrical device. Typically, a plurality of electrical devices are mounted on the mounting plate. The

System comprises the mounting plate and at least one electrical device in the mounted as well as in the unmounted

Condition. The electrical devices can be arranged in rows on the mounting plate, as is known from DIN rail mounting. However, this arrangement is not required.

The method for automated assembly of the system is carried out using at least one gripping or holding tool and an assembly tool. Preferably, a combined gripping

or holding and assembly tool is used, especially if the respective electrical device is gripped in the area of the fastening means, and the fastening means are

The positioning of at least one electrical built-in device with the holding tool on the mounting plate preferably brings the electrical built-in devices individually into their respective positions on the mounting plate.

The automated assembly of at least one electrical

The installation of the device on the mounting plate is carried out using an installation tool, depending on the type of fastening device. The installation tool can, for example, be designed as a screwdriver for fastening screws. Typically, the installation tool is movable relative to the device being held in order to actuate the fastening device.

Further preferably, the built-in device has indentations on its housing body for holding with a holding tool for automated assembly. The indentations can, for example, be formed on opposite sides of the housing body, so that the housing body can be gripped between gripping arms of a pincer gripper. In this case, the indentations preferably have a pyramid-shaped contour, so that the built-in device can be automatically positioned on a corresponding holding tool. Alternatively, the indentations can have a

Bayonet lock for bayonet-like engagement with a bayonet-shaped gripper of the holding tool. Preferably, the gripping contour is arranged in the area of the fastening means, so that a combined tool can be used to

For example, a screwdriver, such as a Phillips screwdriver, can be arranged in the middle of the gripper to hold and assemble the device.

To operate the fastening screw. Accordingly, a screwing tool can be arranged in the center of the bayonet-shaped gripper.

Further preferably, the fastening means are designed as fastening screws, wherein the fastening screws preferably have a shaft with at least one threaded area and a threadless area, and further preferably the fastening screws are freely rotatably held in a screw dome. The fastening screws enable simple and reliable installation of the electrical devices on the

Mounting plate. Appropriate screwing tools can also be used reliably for assembly. The threadless section of the screw shaft allows the fastening screw to rotate freely in the screw boss. The threaded section can be screwed into the fastener receptacle to secure the electrical

The built-in device is to be mounted on the mounting plate. A screw head can hold the housing body against the

The support surface is preferably a

End face of a screw boss. Large contact forces can be exerted on the support surface via the screw head. In the case of contact via the screw head, the fastening screw can be held freely rotatably on the housing body. Further preferably, the fastening screws are guided through the housing body. Particularly preferably, the

Fastening screws have an insertion tip that makes it easier to find the fastener receptacle and position the fastening screws in the fastener receptacles. The fastening screws are particularly preferred as

Phillips screws, hexagon socket screws, or Torx screws. These designs facilitate automatic screwing in of the fastening screws.

Assembly tools can reliably engage the corresponding fastening screws and large torques can be applied to the fastening screws.

Further preferably, the built-in device has contacting means in the area of the fastening means for electrically contacting the mounting plate and/or for contacting

Fastener receptacles of the mounting plate. This ensures automatic contact during installation by the contact means, so that an electrical connection can be established in the area of the fasteners, for example as a ground connection for the built-in device or to provide a supply voltage. This means that the area of the

Mounting plate can be used efficiently to contact the

The contacting means are preferably

Contact sleeves, whereby the fastening means are guided through the contact sleeves. Thus, the

Contact sleeves automatically press against the mounting plate or the fastening device holders during installation of the built-in device, in particular the counter-contacting means of the

Pressed fastener receptacles. The contacting means can be connected to an electrical potential of the built-in device, for example, in the manner of a flag attached to the respective contacting means.

Further preferably, the built-in device has at least one electrical contact element for the automated contacting of at least one electrical counter-contact element of the mounting plate, in particular for the automated contacting of the at least one electrical counter-contact element in the manner of a

Plug-in contact. The electrical device is thus contacted from its side facing the mounting plate.

Bottom. Via the contact elements and the corresponding

Counter contact elements can make contact automatically during

The electrical device can be mounted on the mounting plate, so that no additional effort is required to contact the electrical device. The at least one electrical contact element and the at least one electrical

Counter contact element can be used as corresponding pin and

Socket contacts can be designed to establish the electrical contact. Alternatively, the at least one electrical contact element and the at least one electrical

Counter contact element a plurality of corresponding pin and

Have socket contacts so that multiple electrical connections can be established simultaneously. The at least one electrical contact element and the at least one electrical mating contact element can thus be designed in the manner of plug connectors with multiple electrical contacts.

Further preferably, the built-in device has at least one electrical contact element for connection to at least one conductor track of the mounting plate, wherein the at least one electrical contact element is designed in particular in the manner of a spring contact element. Analogous to the contacting of the mating contact elements, the electrical contact to the conductor track on the mounting plate is established here. The conductor track can have any shape and can also be designed as a flat surface, for example. An electrically conductive material on the circuit board is relevant here. Alternatively, the mounting plate itself can be electrically conductive and can be used as a whole as

Conductor tracks are used, in particular, to provide a ground potential. The spring force of the contact element establishes reliable electrical contact between the contact element and the conductor track.

In both of the aforementioned cases, the electrical contact elements allow for direct contact during assembly, further simplifying installation. The mounting plate can be prepared accordingly, preferably automatically, before installing the built-in devices.

Subsequent cabling of the built-in devices can thus be reduced or even eliminated.

Further preferably, the fastening means of the at least one electrical built-in device are designed as fastening screws, and the fastening means receptacles are designed as

Mounting plate, and/or the fastener receptacles are designed as threaded bushings corresponding to the fastening screws and held on the mounting plate. The

Fixing screws allow for simple and reliable

Mounting of the electrical devices on the mounting plate.

To attach the electrical devices, the fastening screws can be screwed into the threaded holes in the mounting plate. The threaded holes can be cut into the mounting plate, or the mounting plate can have holes or

Recesses into which threaded sleeves are inserted to form the threaded holes. Alternatively, holes can be formed in the mounting plate for the fastening screws to pass through, and the nuts are held on the mounting plate to fasten the fastening screws. The cage nuts can be held in a rotationally secure manner so that the fastening screws can be screwed into them without the nuts having to be held during assembly. Accordingly, a cage of the cage nuts is attached to a hole in the mounting plate, for example by press fitting, and the nut of the cage nut is held rotationally fixed in the cage and thus on the mounting plate. Alternatively, the threaded bushings can be attached to the mounting plate, for example by pressing them into holes in the mounting plate.

By pressing in, the threaded bushings can be held rotationally fixed to the mounting plate. These fastenings have the advantage that they can be automatically pressed into the desired position on the back of a hole matrix carrier plate by a robot and can also be automatically connected to each other with conductors.

This further simplifies installation. The mounting plate preferably has a grid with a corresponding arrangement of threaded holes or holes for universal mounting of the built-in devices. This allows the fastener receptacles to be attached to the mounting plate or formed within it as required.

Further preferably, the at least one electrical built-in device has contacting means in the area of the fastening means, and the fastening means receptacles have counter-contacting means corresponding to the contacting means of the fastening means of the at least one electrical built-in device for electrically contacting the contacting means in the area of the fastening means, or the

Fastener receptacles are designed as counter-contacting means corresponding to the contacting means of the fastening means for electrical contacting of the

Contacting means in the area of the fastening elements. This ensures automatic contact between the contacting means and the

Counter-contacting means, so that an electrical connection can be automatically established in the area of the fastening means and counter-contacting means when mounting the respective built-in device on the mounting plate, for example as a ground connection for the built-in device or to provide a supply voltage. This allows the surface of the mounting plate to be used efficiently for contacting the built-in device.

Threaded bushings can be designed to accommodate fastening means of the at least one built-in device, which fastening means are provided with a fastening screw. The contacting means can be connected to an electrical potential of the built-in device, for example in the manner of a flag attached to the respective contacting means.

Further preferably, the counter-contacting means are electrically connected to an electrical conductor, in particular an electrical cable conductor, or the counter-contacting means have electrical connecting means for connection to an electrical conductor, wherein the electrical connecting means are designed in particular as cutting contacts.

The electrical connection means are connected to the contacting means or the electrical connection means are arranged on the side of the counter-contacting means facing away from the contacting means. Via the electrical conductors or the connection means, a

A further electrical connection of the at least one built-in device mounted on the mounting plate can be made on the side of the mounting plate opposite the built-in device, whereby the electrical connection is already made before the corresponding

built-in appliance can be manufactured. For example, the

The connecting means can be designed with the electrical conductor crimped to the mating contact means, for example, as a threaded bushing. Alternatively, the mating contact means can have a contact terminal as the connecting means, for example, an insulation displacement terminal. The insulation displacement terminal is preferably designed with an insulation-cutting element.

Further preferably, the at least one electrical built-in device has at least one electrical contact element and the mounting plate has at least one electrical mating contact element for automated contacting, in particular for automated contacting in the manner of a plug-in contact.

Alternatively, the at least one electrical contact element and the at least one electrical mating contact element can have a plurality of corresponding pin and socket contacts, so that several electrical connections can be established simultaneously with one contact element and one mating contact element. The at least one electrical contact element and the at least one electrical mating contact element can thus be designed in the manner of plug connectors with several electrical contacts. The contacting of the respective electrical built-in device takes place from its underside facing the mounting plate. The contact elements and the corresponding counter-contact elements allow the contact to be made automatically during assembly of the respective electrical

device on the mounting plate, so that no additional effort is required to contact the respective electrical

Finbaugerät is required. In addition to the electrical

For contacting, the electrical contact elements and counter-contact elements can be designed in such a way that a mechanical connection is created between them when contacting is made.

This allows the built-in device to be held particularly reliably to the mounting plate.

Further preferably, the at least one electrical counter-contact element is electrically connected to an electrical conductor, in particular an electrical cable conductor, or the at least one electrical counter-contact element has electrical connecting means for connection to an electrical

Conductors, whereby the electrical connecting means are designed in particular as cutting contacts.

Mounting plate mounted built-in device. Preferably, the at least one electrical counter-contact element is connected to the electrical conductor on its side facing away from the at least one built-in device, or the electrical connecting means are arranged on the side of the at least one electrical counter-contact element facing away from the contacting means. For example, the connecting means can be designed with the electrical conductor that is crimped to the at least one electrical counter-contact element. Alternatively, the at least one electrical counter-contact element can have a contact terminal as a connecting means, for example as

Insulation displacement terminal. The insulation displacement terminal is preferably designed with an insulation-cutting element.

Further preferably, the mounting plate has at least one conductor track, and the at least one electrical built-in device has at least one electrical contact element for automated contacting of the at least one conductor track, wherein the at least one electrical contact element is designed in particular in the manner of a spring contact element. Analogous to the contacting of the mating contact elements, electrical contact is established here with the conductor track on the mounting plate. The conductor track can have any shape and can also be flat, for example. An electrically conductive material on the mounting plate is relevant here.

Alternatively, the circuit board itself can be electrically conductive and serve as a conductor track, in particular to provide a ground potential. Due to the spring force of the

Contact element creates a reliable electrical contact between the contact element and the conductor track.

Further preferably, the mounting plate is designed as a perforated plate with a regular arrangement of holes, and the

Fastener receptacles can be mounted in the holes of the mounting plate, in particular by press fitting, and/or the at least one electrical mating contact element can be mounted in the holes of the mounting plate, in particular by press fitting. The arrangement of the holes can be in accordance with a standard dimension of the built-in devices in order to be able to easily mount the built-in devices thereon. Based on the holes in the mounting plate, the fastener receptacles or the mating contact elements can be positioned and attached to the mounting plate as required to enable individual installation. The fastener receptacles and/or the mating contact elements can be easily attached to the mounting plate in an automated manner.

The same applies to the formation of threaded holes in the

Mounting plate with an appropriate tapping tool.
