Description

The present invention relates to a system for fixing a carrier plate in a tubular housing body. Furthermore, the invention relates to a valve device.

In industrial automation, carrier plates or circuit boards are often mounted in hard-to-reach places. For example, this occurs when carrier plates must be inserted into geometrically limited housing openings and fixed on the inside of the housing.

The publication WO 2004/003573 A1 discloses an electrical energy meter having a base adapted for attachment to a support surface, a current sensor assembly having a plurality of contact blades adapted to electrically contact an electrical conductor, and a current transformer mechanically coupled to and electrically connected to the base Contact legs is coupled.

The electrical energy meter further comprises a printed circuit board holding element which has a fixed edge portion coupled to the base and a first carrier adjacent to the edge portion. The first bracket has first and second legs each extending from the edge portion and the base and each configured to securely engage the main circuit board.

Further, the document discloses DE 20 2016 102 603 U1 a plug-in contact set from the prior art.

It is the object underlying the invention to provide an efficient and cost-effective concept for fixing carrier plates in tubular housing bodies. Furthermore, the object underlying the invention to provide a system for fixing a support plate in a tubular housing, which requires neither screws nor adhesive to the carrier plate as simple as possible in a tubular housing and expand.

This object is solved by the subject matters according to the independent claims. Advantageous embodiments are the subject of the dependent claims, the description and the drawings.

According to a first aspect, the object is achieved by a system for fixing a carrier plate in a tubular housing body. The system comprises a carrier plate with at least one connector, a frame element, wherein the frame element is designed for connection to the carrier plate, a tubular housing body, wherein the housing body is formed with at least one insertion opening for insertion of the carrier plate. Furthermore, the housing body comprises at least one connector opening for passing the connector from an inner side of the housing body to an outer side of the housing body. In addition, the system comprises a clamping device, which is formed elastically deformable against a restoring force, wherein the clamping device is designed for arranging on the frame member; the carrier plate can be fixed in the housing body by the restoring force. This makes it possible to connect the support plate outside the housing body with the frame member and insert the support plate including the frame member through the insertion opening in the housing body and to place at a designated location. Here, in a simple manner one or more connectors which are arranged on the carrier plate, are passed through the one or more connector openings of the tubular housing body. By the subsequent biasing and insertion of the clamping device, it is possible to fix the carrier plate at the predetermined location in the housing body by the restoring force of the clamping device. Due to the fact that the clamping device by the elastic deformation exerts a restoring force on the support plate and or on the frame member, by overcoming the restoring force, the clamping device can be removed again from the support plate, whereby the support plate in a simple manner again from the tubular housing body can be removed.

The circuit board or carrier plate may be any form of a circuit board or a carrier of other electronic components.

The carrier plate may have one or more connectors, which are designed for separating and connecting lines. The connectors are connected by positive engagement with each other corresponding connector parts, where they can be secured, for example by spring force or a thread against unintentional release of the connectors and the connector parts. The plug parts may be formed, for example, as sockets, couplings, or sockets for electrical, optical or fiber optic connectors.

The frame member may be formed here as a simple plastic component, which surrounds the carrier plate partially or completely. Alternatively, the frame element can also be made Aluminum or other suitable material.

The tubular housing body can be realized as a simple housing, which is set up from an outside for the operation of a device suitable for industrial automation. The housing or the housing body usually has an insertion opening on a lower side, which is used as an opening for introducing the carrier plate. Similarly, the selbige insertion opening is also used as an interface, for example, for mounting the housing body on a drive of industrial automation.

The clamping device may be formed as a simple plastic component, which can exert a restoring force by a suitable geometric configuration by deformation. This can be used in addition to plastic and a suitable metal or other material. Particularly suitable as a clamping device is a component which can be deformed manually by a user and can be introduced in the deformed state to the suitable location for fixing the carrier plate.

If a user has placed the prestressed clamping device in the appropriate location for fixing the carrier plate and the deformation of the clamping device decreases, the clamping device clamps the carrier plate at the desired location by its restoring force. For example, the clamping device can also be supported by the action of a spiral spring, a leaf spring or a plate spring.

According to a preferred embodiment, the housing body has a trough for arranging the carrier plate. By a trough on the housing body, it is particularly easy to arrange the support plate including the frame member at the appropriate location in the housing body. In this case, the trough may additionally comprise suitable lubricants or frame elements which facilitate the efficient and, above all, precise arrangement of the carrier plate inside and half of the housing body.

According to a further preferred embodiment, the housing body has a support device in order to support the clamping device on the inside of the housing body relative to the frame element. As a result, the technical advantage is achieved, in particular, that the clamping device can be arranged so that it can not slip and be precisely positioned in the housing body, thus ensuring optimum fixing of the carrier plate. Ideally, the support means and a predetermined point at which the carrier plate is to be arranged in the housing body, matched to each other, so that the clamping device can not slip when fixing the placed carrier plate. Thus, a targeted fixing of the carrier plate is ensured. In this case, it is particularly conceivable that the support means is made in one piece with the housing body. As a suitable material for the production of the support means and the housing body, for example, offer plastics, which can be produced by injection molding. Alternatively, however, a production of metal, for example in a die-casting process is conceivable.

According to a further preferred embodiment, the carrier plate defines in a state arranged in the trough of the housing body a plane which is arranged parallel to an insertion direction of the clamping device in the housing body. By arranging, or by the definition of the plane of the support plate, the clamping device can be introduced very easily parallel to this plane through the insertion opening. The simple insertion of the clamping device now requires no special effort for the placement in the right place in the housing body. Rather, the clamping device can be introduced straight through the insertion opening directly to the appropriate location for fixing the support plate and clamped by the restoring force. The same advantage results for a user when removing the clamping device from the housing body. This can be intervened in a straight line through the insertion opening of the housing body on the inside, wherein the clamping device can be deformed against its restoring force and removed from the housing body. This results overall in a simplification of the assembly, as well as the disassembly of the carrier plate in the tubular housing body.

In order to produce the clamping device in a particularly simple manner and with low production costs, the clamping device has at least one first clamping element and one second clamping element. When deforming the clamping device to arrange this to the support plate in the housing body, or to remove the clamping device from this position, the first clamping element and the second clamping member move relative to each other, whereby the restoring force can be generated or degraded.

According to a particularly preferred embodiment, the clamping device is wedge-shaped. In this case, it is particularly possible to produce the clamping device as a one-piece molded component. The wedge-shaped or v-shaped design of the clamping device thus forms two opposing arms, which each form the first clamping element and the second clamping element.

According to a further particularly preferred embodiment, the clamping device has a first sawtooth section for engagement in the frame element. In this case, the first sawtooth section is preferably located on that arm of the clamping device which has the first clamping element and comes into direct contact with the frame element. As a result, the clamping device is additionally secured against slipping from the frame element, or from the support plate. It would also be conceivable to arrange an additional sawtooth section on the second clamping element, or on the opposite arm of the wedge-shaped clamping device. Ideally, the clamping device could thus be additionally secured against slipping, since this sawtooth portion can engage a corresponding point on the support means in the housing. Thus, by the arrangement of sawtooth sections either on the first clamping element and / or on the second clamping element, each with corresponding active surfaces, the slipping safety of the carrier plate in the housing body is additionally secured.

According to a further preferred embodiment, the frame element has a second sawtooth section for engagement in the clamping device. This additionally improves the technical advantage of securing against slipping. In other words, thus the first sawtooth portion of the clamping device engages in the fixing position of the support plate with the second sawtooth portion of the frame member in engagement. The intermeshing makes it impossible to loosen the carrier plate in the housing body accidentally or by vibration. As a result, the fixation of the support plate is particularly safe, which overall increased reliability and reduced maintenance of the entire device can be achieved.

In order to operate the clamping device particularly easily, or to attach the clamping device particularly easy to the desired location for securing the support plate, or to remove it from this point again, the clamping device on a handle means. This is preferably arranged at one end of the first clamping element of the clamping device, whereby a manual actuation of the clamping device is particularly simple. The gripping means is formed for example as a simple trough or notch, wherein the trough or notch can be arranged directly on the first sawtooth section. Thus, the deformation of the clamping device can be realized manually very easily, wherein a user can bring about the deformation in each case only by operating or engaging in the trough of the handle means. This applies both when inserting the clamping device into the housing body and when removing the clamping device from the housing body.

According to a further particularly preferred embodiment, the clamping device is integrally formed. On the one hand this reduces the manufacturing costs of the clamping device, on the other hand, the clamping device is characterized by particularly unsusceptible to wear or damage.

According to a further embodiment, the frame element has latching means for fixing a carrier plate. As a result, for example, the technical advantage is realized that the carrier plate can be fixed to the frame element in a particularly precise and slip-proof manner. The locking means may be formed here as a simple projection or notch in the frame member, whereby a clear placement of the support plate when fixing the support plate to the frame member is possible. Alternatively, however, it is possible to connect the carrier plate by additional clamping or clamping means, wherein the fixing by means of an adhesive is also possible.

According to a second aspect, the object is achieved by a valve device having a drive and a control head for controlling the drive, wherein the control head has a system for fixing a carrier plate in a housing body according to one of the preceding embodiments.

According to a further advantageous embodiment, an electrical connection of the drive with the connector is electrically connected.

According to an additional embodiment, the carrier plate has an operating element for controlling a function of the drive.

The invention will be explained in more detail below by means of embodiments with reference to the accompanying schematic drawings.
