Definitions

  • the present invention relates to a device socket, a device plug and a device plug system consisting of the device socket and the device plug.
  • the cable connection socket is usually provided in a hole cutout in a wall of the device housing in order to provide the cable connection.
  • the external cables are fastened in the cable connection socket using clamping screws.
  • the device-side cables can be connected to the cable junction box using tabs or solder connections. In this way, electrical contacting between the device-side and device-external cables is achieved.
  • cable junction boxes In order to counteract this, cable junction boxes often have a relatively large installation space in comparison to the dimensions of the hole cutout on their side provided for connecting the cables external to the device. As a result, the appearance of the devices connected in this way is impaired and their space requirement is increased. Furthermore, in particular for metallic device housings, it is necessary to provide a ground contact in order to prevent dangerous leakage currents or arcing on the user. These are often screwed onto the housing as separate grounding cables. However, there is a risk that the separate grounding line will be loosened. Furthermore, the appearance of the devices is deteriorated by the protrusion of the ground wire from the case.
  • the aim is to ensure that the installation space defined by the hole cutout is used as optimally as possible for the connection of the respective cables.
  • a first aspect of the present invention relates to a device socket for releasable attachment in a hole cutout in an electrical device.
  • the device socket has a socket body with an outer wall that extends at least partially along and otherwise within a cylindrical shape.
  • the socket body also has a connector receptacle, which is surrounded by the outer wall and has an insertion opening for inserting a connector in an insertion direction, from which the connector receptacle extends.
  • the device socket also has at least two electrical contacts which are arranged within the cylindrical shape and extend in such a way that they can be electrically contacted with a plug inserted through the insertion opening.
  • One of the contacts is an earth contact.
  • the device socket also has a ground connection, which is electrically coupled to the ground contact and extends laterally in one direction away from the outer wall and essentially orthogonally from an axis of rotational symmetry of the cylindrical shape.
  • a simple connection possibility of device-side and device-external cables is provided by means of a device socket.
  • the number of assembly steps and the complexity of the assembly for connecting the respective cable contacts can be significantly reduced.
  • the risk of assembly errors and / or assembly inaccuracies can thus also be reduced.
  • the special shape of the socket body which extends at least partially within a (virtual) cylindrical shape, ensures that the functionality required for the device socket is compactly available within a defined installation space can be put. The space required for the device socket can thus be reduced.
  • a component that is essential for safety is defined by the ground connection with simple means with regard to the can body and is made available compactly with it.
  • grounding connection can interact, for example, with the wall of the device housing or with the aid of additional fastening means or fastening structures in such a way that twisting of the device socket is prevented.
  • the device socket according to the invention provides a (twist-proof) possibility of connecting device-side and device-external cables via a hole cutout, which overcomes the aforementioned disadvantages of the solutions known from the prior art.
  • the can body can have a circular contour with a circular diameter in the range from 10 mm to 100 mm in an area in which the outer wall extends along the cylindrical shape, preferably in the insertion direction.
  • the cylindrical shape can have a diameter in the range from 10 mm to 100 mm.
  • the can body can also extend longitudinally along the rotational symmetry axis, preferably with a longitudinal extent in a range from 10 mm to 100 mm.
  • the device socket can be used for a large number of different and, in particular, common hole cutouts. It can also be achieved that the smallest possible installation space is required by the device socket. This can improve the appearance of the devices to be connected and also reduce their effective installation space.
  • the can body or its outer wall can have two sections, preferably opposite one another with respect to the axis of rotational symmetry and further preferably parallel and in particular straight, within the cylindrical shape, which are separated by at least one second section (or preferably two, preferably opposite one another with respect to the axis of rotational symmetry) substantially (second) sections extending along the cylindrical shape.
  • the first sections and / or the second sections can be evenly distributed over the circumference of the can body or the cylindrical shape.
  • the can body can thus have at least two straight, opposing first sections which are connected by at least one second section extending along the cylindrical shape. It is thereby achieved, for example, that the can body can be received in a substantially round hole cutout so that it cannot rotate.
  • An anti-rotation device can thus be provided with simple means. Furthermore, the space required for the device socket can be further reduced by providing the straight first sections. Finally, the assembly of the plug is also made easier, since the device socket is easier to grasp on the straight sections.
  • the ground connection can extend away from one of the second sections.
  • the device socket is provided with an orientation.
  • the grounding connection can also serve as a coding means in order to clearly position the device socket in the hole cutout. Furthermore, it can be achieved that the installation space saving and assembly simplification achieved by the provision of the first sections is not adversely affected by the ground connection. The compactness and mountability of the device socket is further improved by the selected arrangement.
  • the grounding connection can extend flat, preferably in a plane orthogonal to the axis of rotational symmetry and / or in a plane orthogonal to the direction of insertion.
  • the ground connection can thus be provided, for example, parallel to the plane in which the insertion opening is also provided. This is particularly advantageous since it enables electrical contact with the wall of the device housing, which has the hole cutout, and this is achieved with simple constructional means. Furthermore, by providing a flat ground connection, the contact area with the wall can be enlarged and the electrical coupling of the two components can be improved.
  • the ground connection can be connected to the ground contact via a connecting section in order to form a ground contact element.
  • the earth connection and the earth contact can be integrally formed with one another via the connecting section.
  • the contacts and preferably the grounding contact element can be designed as a stamped and bent part for this purpose.
  • the ground connection and the ground contact are reliably electrically and mechanically coupled to one another. Furthermore, the manufacture and the assembly of the respective elements can be simplified and thus costs can be reduced.
  • the connecting section can also preferably extend laterally along the outer wall and preferably essentially parallel to the axis of rotational symmetry.
  • the connecting section can also extend along the second section, which preferably has the ground connection.
  • a further contact area coupled to the ground contact can be provided by means of the connecting section on the outer wall of the device socket. This makes it possible to provide additional connection options with the grounding contact on the outside of the device socket.
  • the range of functions of the device socket can thus be expanded without increasing the installation space of the device socket.
  • the ground connection can be provided on a section of the outer wall, preferably on a section of the second section, which is designed as a recess with respect to the cylindrical shape toward the axis of rotational symmetry.
  • the recess can extend in a plane parallel to the axis of rotational symmetry.
  • the connecting section can extend along the recess and preferably within the cylindrical shape.
  • the connecting section of the earth connection can be provided in the recess without the device socket experiencing a width increase in the radial direction.
  • the compact design and shape of the device socket can be further improved.
  • the ground connection can have at least one, preferably two ground connection openings, the (geometric) center point of which is preferably at a distance from the axis of rotational symmetry in the range from 10 mm to 50 mm.
  • the two ground connection openings can preferably be arranged mirror-symmetrically with respect to the ground connection and / or with respect to a radial of the rotational symmetry axis.
  • the device socket can be used for common hole cutouts.
  • the device socket can be made compact by the dimensioning.
  • the earth connection can be secured through the earth connection openings, for example by means of screw connections on the wall of the device housing.
  • a section extending along the cylindrical shape, preferably at least one of the second sections, can be seen in the direction of the axis of rotational symmetry over an angular range of at least 20 ° or at least 30 ° or at least 40 ° or at least 60 ° or at least 90 ° or extend at least 120 ° or at least 130 °.
  • the second sections essentially have a part-circular profile. This makes it possible to make the device socket as compact as possible and to use it in conjunction with a large number of common industrial cutouts.
  • the device socket can furthermore have a support section in order to rest on an edge region of the hole cutout which at least partially accommodates the device socket (or the socket body) (but preferably at least the rear side of the socket body).
  • the support section can preferably be formed by a preferably ring-like projection that at least partially circumferentially surrounds the outside of the outer wall (preferably away from the can body).
  • the support section can preferably have sealing means, such as a rubber lip, in order to protect the device housing against the ingress of dirt and / or moisture.
  • the device socket is attached in the hole cutout by means of a defined area of the socket body.
  • a preferred mounting direction can also be indicated by such a structural design of the device socket, so that the mounting is made easier.
  • it is also possible to use the device socket in applications that place increased demands on the tightness of the device e.g. IP protection class IP67 and higher).
