Description

The present disclosure relates generally to a connector for connecting technical media. In particular, a connector for a direct current connection is disclosed.

An overarching goal is to design the power supply for industrial systems in the future via a regulated and open direct current network and to digitize the industrial energy supply architecture. The use of direct current corresponds not only to regenerative energy sources and fail-safe local electricity storage systems, but also to industrial consumers. The elimination of a large number of rectifiers in the individual system components increases their reliability and overall energy efficiency. In addition, digital communication improves energy flexibility. With a decentralized network control and integrated electricity storage, an energy flow can react flexibly and robustly to fluctuating external network quality or energy supply. Renewable energies can be integrated directly and conversion losses from AC to DC voltage can be avoided. In addition, energy savings result from the simpler use and buffering of braking energy, known as regenerative braking, in direct current networks.

To ensure the safety and reliability of such a regulated and open direct current network, its electrical connections must not be opened in an uncontrolled manner. For this purpose, electromechanical locks of a connector are known from the prior art. The document DE 10 2017 118751 A1 describes a camshaft as a lock. However, locks can be opened by a short distance of the bolt and therefore do not meet the requirements for security and reliability of a direct current network.

The invention is therefore based on the object of specifying a connector which reliably fixes a plugged-together state against manual manipulation. An alternative or more specific task is to ensure that the mated state can only be opened in the de-energized state.

The object is achieved with the features of the independent claim. Appropriate configurations and advantageous developments of the invention are specified in the dependent claims.

Embodiments of the invention are described below with partial reference to the figures.

According to one aspect, a plug connector for an electrical plug connection is provided. The connector comprises a first connector part with a housing and at least one contact element, and a second connector part with a housing and at least one contact element. The first plug connector part and its at least one contact element can be plugged together with the second plug connector part and its at least one contact element for the electrical plug connection when the first plug connector part and the second plug connector part are plugged together. The first plug connector part comprises an electromotive drive and a first screw connection part rotatably coupled to the drive. The second connector part comprises a second screw connection part which is secured against rotation and which can be screwed to the first screw connection part by means of the drive in order to fix the plugged-together state of the first connector part and the second connector part.

Exemplary embodiments of the plug connector can fix the plugged-together state by means of the screw connection over a large number of revolutions of the first screw connection part. The large number of revolutions can be achieved quickly, reliably and without additional manual effort thanks to the electric motor drive and excludes manual opening of the assembled state.

The second connector part can be a non-drive connector part.

The drive can be coupled to the first screw connection part for rotating the first screw connection part relative to the housing of the first plug connector part. Alternatively or in addition, the drive can be permanently coupled to the first screw connection part.

The first screw connection part can comprise a threaded bolt or threaded pin. The second screw connection part can comprise a threaded sleeve. Alternatively or in combination, the first (or a further first) screw connection part can comprise a threaded sleeve. The second (or a further second) screw connection part can comprise a threaded bolt or threaded pin.

On the first and second connector parts, the at least one contact element can be arranged parallel to the first or second screw connection part.

The first and second connector parts can each have a contact portion on which the respective at least one contact element protrudes from the respective housing (preferably with an optional protective sheathing of the contact element not being regarded as part of the housing). The first or second screw connection part can be arranged laterally next to the contact section on the respective plug connector part.

The first connector part and the second connector part can each comprise at least two modules. The modules can each occupy or determine a module space on the contact section. Alternatively or additionally, the respective contact elements can be spatially and / or functionally grouped in one or each module. The drive can occupy one or half a module slot. The module space occupied by the drive can preferably be adjacent to the first screw connection part.

The first plug connector part can comprise the drive and the first screw connection part rotatably coupled to the drive on one or both sides of the contact section.

The first connector part and the second connector part can each comprise control contact elements on the contact section, preferably on the module space occupied by the drive. In the assembled state, the control contact elements can be in contact in pairs for controlling and / or supplying the electromotive drive.

The connector can further comprise a control unit. The control unit can be designed to control or regulate the drive, preferably via the control contact elements. As an alternative or in addition, the control unit can be arranged: on the second plug connector part, optionally in signal connection with the drive via the control contact elements; on a line to the second connector part, optionally in signal connection with the drive via the line and the control contact elements; on the first connector part; and / or on a line to the first connector part, optionally in signal connection with the drive via the line.

The plug connector can furthermore comprise a sensor for detecting a current flow through the contact elements in the assembled state. The sensor can be in signal connection with the control unit. The control unit can be designed to control the drive for fixing or maintaining a screwed state of the first and second screw connection parts, for example if the sensor detects a current flow. The sensor can comprise a Hall sensor for detecting a magnetic field induced by the current flow or a voltage sensor connected in parallel to the current flow through the plug connector for detecting a voltage drop.

The first connector part can comprise a thrust bearing. The axial bearing can be designed to transmit a tensile force from the first screw connection part to the housing of the first plug connector part.

The second screw connection part can be axially longitudinally movable, for example between an open position and a plugged-together position (which is preferably assumed in the plugged-together state). The second plug connector part can comprise an energy storage device, preferably a spring, which acts on the second screw connection part with force from the open position in the direction of the plugged-together position. In other words, the energy store can preload the second screw connection part into the open position.

The contact elements can be designed to produce the electrical plug connection for a direct current in the assembled state.

The first connector part can be a plug (for example with contact pins as the at least one contact element) and the second connector part can be a socket (for example with contact sleeves as the at least one contact element) for the electrical plug connection.

On the first and second connector parts, the at least one contact element in each case can comprise at least one contact pin and / or at least one contact sleeve. The contact elements can be arranged and designed for plug-in connection in pairs when plugged together.

The invention is explained in more detail below with reference to the attached drawings using preferred exemplary embodiments.

1 shows a schematic sectional view of a first exemplary embodiment of a plug connector for an electrical plug connection. The connector is generally identified by the reference number 100 designated.

The connector 100 comprises a first connector part 200 with a housing 202 and at least one contact element 204 at a contact section 206 of the first connector part 200 . The connector 100 further comprises a second connector part 300 with a housing 302 and at least one contact element 304 at a contact section 306 of the second connector part 300 .

The first connector part 200 and its at least one contact element 204 are with the second connector part 300 and its at least one contact element 304 can be plugged together to produce the electrical plug connection, ie when the first plug connector part is plugged together 200 and the second connector part 300 .

The first connector part 200 includes an electric motor drive 208 and one with the drive 208 rotatably coupled first screw connection part 210 . The coupling can be a gear 212 of the drive 208 , optionally on the output side of a gearbox of the drive 208 , include. The coupling can also be a ring gear 214 on the first screw connection part 210 include. The ring gear 214 is preferably rotationally fixed to the first screw connection part 210 connected. The ring gear 214 can be integrally in one piece with the (preferably metallic) first screw connection part 210 be trained.

Preferably the gear meshes 212 permanently with the ring gear 214 . In a variant of this or any other embodiment, the gear is 212 the pinion of the coupling. A holding torque of the drive 208 (that for example according to a gear ratio between the gear 212 and the ring gear 214 is enlarged) can prevent manual rotation of the first screw connection part. Alternatively or in addition, the first screw connection part is 210 inaccessible in the assembled state, for example by the housing 202 and 304 the first screw connection part 210 enclose and / or the first screw connection part 210 of one with the case 202 rotatably connected cylinder jacket is surrounded.

The second connector part 300 includes an anti-twist device 308 for the anti-twist (and optionally axially movable) arrangement of a second screw connection part 310 on the second connector part 300 (for example on the housing 302 ).

Furthermore, the first embodiment only includes the first connector part 200 the first screw connection part 210 with the drive 208 for rotating the associated first screw connection part 210 . The second connector part 300 is drive-free. A variant of this or any other embodiment includes on both sides of the connector 100 , ie, also on the second connector part 300 , a screw connection part with a drive for rotating the associated screw connection part. For example, on each side of the contact sections 206 and 306 a twist-proof screw connection part and a screw connection part driven for rotation can be arranged in each case. This allows from either side of the connector 100 (ie, both from the side of the first connector part 200 as well as from the side of the second connector part 300 ) in each case the plugged-together state can be fixed by the respective drive screwing the screw connection (for example on the side of the connector assigned to it 100 ) causes. As a result, the releasability of the mated state is a logical AND operation (conjunction) of a release of the mated state from the side of the first connector part 200 and from the side of the second connector part 300 .

As an alternative or in addition, the first connector part can be used in each exemplary embodiment 200 be implemented as a plug. The second connector part 300 can be implemented as a built-in or built-in socket.

Optionally, the contact sections include 206 and 306 Control contact elements arranged in each case at corresponding points 205 or. 305 for controlling and / or supplying the drive 208 . For example, the control contact elements are 205 in the housing 202 of the first connector part 200 in contact with the drive 208 , with an H-bridge for pulse width modulation (for example with a commutator motor in the drive 208 ) of the current in the drive 208 or with a step control (for example with a stepper motor in the drive 208 ).

The drive 208 can from the side of the first connector part 200 (for example from the side of a plug as the first connector part 200 ) are driven. As an alternative or in addition, the control contact elements electrically connected in pairs when plugged together make it possible 205 and 305 controlling the drive 208 from the side of the second connector part 300 (for example from an installation side as a second connector part 300 ). When the drive 208 is housed in one or half a module space, are the control contact elements 205 and 305 preferably in the contact section 206 of the drive 208 occupied module space in the first connector part 200 and at a corresponding point of the contact section 306 in the second connector part 300 arranged.

The drive 208 can be controlled via a control unit, for example by the control unit having a supply voltage and / or a current of the drive 208 controls. The control unit can be outside the connector 100 or in one of the connector parts 200 or 300 be arranged.

The drive 208 , the control unit or a drive 208 The comprehensive and / or controlling module can also have a sensor or a sensor interface in the first connector part 200 include. The sensor or the sensor interface can be designed to flow a current through the connector 100 and / or one on the connector 100 to detect the applied voltage. The control unit of the drive can use the sensor or the sensor interface 208 be designed to recognize the current flow and / or the applied voltage and, when the voltage and / or current flow is applied, the plugged-together state through the screwing of the two screw connection parts driven by an electric motor 210 and 310 to fix or to keep fixed. An opening of the connector 100 is then impossible.

The connector 100 , preferably the first connector part 200 and / or the second connector part 300 (the latter optionally via the control contact elements 205 and 305 ), can comprise one or more sensors, for example for detecting a temperature, an end stop of the screw connection of the two screw connection parts, an end stop in the mated state and / or one or more current intensities through the connector in the mated state.

The control contact elements 205 and 305 may include signal contact elements. If one or more sensors in the second connector part 300 are arranged (for example, to detect the end stop of the screw connection) and a control unit in the first connector part 200 or via a line to the first connector part 200 is in signal exchange, the signals from the sensor or the sensors in the second connector part 300 via the signal contact elements 305 and 205 to the first connector part 200 (and if necessary to the control unit).

The first connector part is optional 200 and / or the second connector part 300 modular. The first connector part 200 and the second connector part 300 include in the respective housing 202 or. 302 two, three or more modules each 216 or. 316 . Preferably the drive is 208 (and possibly its control unit) in a module 216 arranged. That from the drive 208 occupied module 216 is preferably one of the outer modules and / or on that side of the contact section 206 arranged that the first screw connection part 210 is adjacent.

At one of the contact section 206 or. 306 opposite side can be the contact insert to each contact element 204 or. 304 comprise a terminal for connecting an electrical line.

For example, all modules 216 and 316 that have no drive 208 and no control contact elements 205 include, be designed as contact inserts. If the drive 208 is integrated in the housing, all modules can be contact inserts. Otherwise, all but one module can be used for the drive 208 (and, if applicable, the control contact elements 205 ) be designed as contact inserts.

Preferred connector sizes 100 , for example the housing 202 and 302 , offer space for two, three or more modules 216 or. 316 .

The resilient mounting makes it possible to use the connector 100 to close without the electromotive fixation being carried out to produce the plugged-together state (and thus the electrical connection) and / or without the electromotive fixing having to be carried out.

Preferably the screw connection parts are 210 and 310 (For example, in addition to fixing the plugged-together state by screwing) designed to pass on a protective earth (PE). The latter function can be implemented due to the preload of the energy store in the assembled state, for example regardless of whether the two screw connection parts 210 and 310 are screwed or are only in contact with the electrical line at the end due to the bias.
