Description

Connector device

[0001] The invention relates to a connector device, in particular for the electrical connection of electrical equipment and / or electrical cables in potentially explosive areas.

[0002] Electrical connectors are generally known from the state of the art in various applications.

[0003] DE 10 2020 121 535 B4 describes a connector device with a plug, a socket, and a gate arrangement that is operatively arranged between the socket and the plug. A cam is assigned to the gate arrangement. To release the connection, a rotary movement is forced by the gate arrangement. The gate arrangement has a separating section and a delay section that serves to slow down the separating movement in order to extinguish any sparks that may arise and / or to cool down hot explosion gases.

[0004] WO 2007 0 719 688 A2 describes a connector device with a pin and a groove which prescribes a sequence of rotating and / or sliding movements of one part of the connector device relative to another part of the connector device for connecting or disconnecting.

[0005] In the publications US 10 033 138 B2, DE 10 2017 112 160 A1, further connector devices with a groove and a cam are described, in which certain movement sequences for releasing and connecting are specified.

[0006] DE 2 730 660 A1 also describes an electrical connector with a plug and a socket. The plug has a rotating ring with cams that interact with a slotted slot on the socket. When the ring is rotated, this causes the plug to move in translation relative to the socket. This enables sequential closing of the power and control contacts.

[0007] DE 20 2008 008 610 U1 describes a locked socket which, among other things, has an insert rotatably mounted in a bearing bush, which can be rotated by turning the plug. Furthermore, a switch is described which, by means of an actuating device, can be switched from an open state to a closed state and vice versa by turning the plug or the insert.

[0008] DE 10 2020 100 655 A1 further discloses a plug and socket arrangement with an electrical switch which contains an actuator with which the socket can be switched into an energized and a de-energized state, wherein the socket has a transmission mechanism with which the rotation of the plug is transmitted into a movement relative to an axis actuating the actuator.

[0009] With the plug-and-socket connection devices described in the prior art, it may happen that the electrical contacts of the plug and the electrical contacts of the socket are pulled apart or held apart depending on the user's movement, so that an arc can occur between the electrical contacts. Such arcs can occur unintentionally over an extended period and impair the product life of such plug-and-socket devices, e.g., through increased contact erosion.

[0010] Based on this, it is the object of the invention to provide an improved connector device which in particular prevents undefined and / or long-lasting arcs from occurring when connecting and / or disconnecting an electrical connection between the plug and the socket.

[0011] This object is achieved with the connector device, in particular for the electrical connection of electrical equipment and / or electrical cables in potentially explosive atmospheres according to claim 1:

[0012] The plug connector device according to the invention comprises a plug and a socket . The plug comprises a plug housing and at least one electrical plug contact held in an insulated manner in the plug housing . The socket comprises a socket housing and a switching device which comprises a rotary element which is mounted rotatably with respect to the plug housing and in which a receiving opening is formed into which the plug can be inserted at least partially (along an axial direction of the socket ) can be inserted into an unlocking position. The rotating element can be rotated in the circumferential direction relative to the socket housing by means of the plug. The socket also has at least one electrical socket contact which is held in an insulated manner in the socket housing and which engages with the electrical plug contact of the plug when the plug is inserted into the receiving opening, for example when it has been brought into the unlocking position. The electrical socket contact is preferably initially switched to a non-conductive state. In particular, the plug can only be moved in a translational manner (in the axial direction of the socket) before the plug is brought into the unlocking position.

[0013] The switching device also has a switching element and an actuating element, the switching element being designed to switch the at least one electrical socket contact from a non-conductive state to a conductive state and vice versa when actuated by the actuating element. The actuating element is rotationally coupled to the rotating element and is designed to rotate ahead of the rotating element when a snapping angle is reached and / or exceeded and to actuate the switching element (abruptly). The snapping angle can be greater than 10°, for example, preferably greater than 20°, particularly preferably greater than 30°. The rotating element is preferably directly coupled in terms of movement to the plug, i.e. without any step-up or step-down, at least in a partial range of the rotational movement before the snapping angle is reached.After reaching the snap angle, the actuating element is accelerated along the direction of rotation relative to the rotating element.

[0014] By preemptively rotating the actuating element when a certain snap-over angle is reached, abrupt actuation of the switching element is possible. This prevents the plug contact from being accidentally and / or improperly held at an undefined distance from the socket contact, which could cause an arc to form between the contacts and damage the connector device.

[0015] A special feature of the plug connector device according to the invention is that the switching device ensures reliable actuation of the switching element, in particular regardless of the actuation speed. The switching device is switched either into a conductive state or into a non-conductive state, with the switching phase between the conductive and non-conductive state being kept as short as possible and being triggered via the actuating mechanism. A switching phase that is maintained permanently (intentionally or unintentionally) can thus be avoided. In addition, the electrical contacts are initially engaged when the electrical socket contact is in a non-conductive state.Only when a certain snapping angle is reached and / or exceeded when the plug is turned does switching occur, in which the electrical socket contact is switched into a conductive state in a rapid switching process. Switching occurs via a snapping mechanism, with a switching phase that can, for example, be in the range of milliseconds or microseconds.

[0016] The actuating element is preferably designed as a, in particular torus-shaped, switching wheel. The rotary element is preferably at least substantially cylindrical. The actuating element is arranged in particular concentrically on the rotary element, whereby the required installation space for the switching device can be reduced. When the rotary element is rotated, the actuating element is preferably designed to be rotationally coupled synchronously with the rotary element before the snap-over angle is reached.

[0017] It is preferred that the actuating element for actuating the switching element be preloaded by rotating the plug in the direction of rotation. The switching device can also be configured to release the preload when the snap-over angle is reached and / or exceeded and to drive the actuating element to actuate the switching element (in the direction of rotation), thereby further shortening the switching process.

[0018] In particular, the switching device has a locking element that is configured to release the rotatability of the rotary element when the plug is brought into the unlocking position. Accordingly, the locking element can be configured to block the rotatability of the rotary element when the plug is not brought into the unlocking position. This can prevent the at least one electrical socket contact from switching into a conductive state when no plug is located in the receiving opening.

[0019] Preferably, the locking element is engaged with the actuating element when the plug is inserted into the unlocking position. The locking element is, for example, toroidal. It preferably has one or more locking pins which extend axially in the direction of the receiving opening. Furthermore, the locking element preferably has at least one pin which projects axially from the locking element opposite to the direction of the receiving opening. The at least one pin is preferably in engagement with the rotating body in such a way that rotation of the rotating body in the circumferential direction is transmitted to the locking element. The actuating element has, in particular, a recess in which the at least one pin is arranged. The recess in the actuating element is preferably designed as an elongated hole extending along the circumferential direction, so that the pin of the locking element forms a driver element for the actuating element.The driver element has a certain amount of play in the circumferential direction. Alternatively, a pin-shaped driver element can be attached to the rotary element and arranged in the recess of the actuating element.

[0020] Preferably, the actuating element has a contour against which a slide can be preloaded by means of a spring element at least substantially orthogonal to the direction of rotation. The contour controls, in particular, a deflection of the slide in the axial direction as a function of the angle of rotation.

[0021] The contour has in particular a vertex between a first contour section, in which the slider is deflected at least substantially orthogonally to the direction of rotation, and a second contour section, in which the slider is deflected by the spring element in the direction of rotation is driven.

[0022] The contour defines a starting point and an end point for the slider, between which the vertex is located. In particular, the contour is mirror-symmetrical about a plane axially extending through the vertex. The contour is, for example, convex. Preferably, the contour is stepless and continuous at the vertex.

[0023] In particular, the switching element is actuated by the actuating element when the slide is located in the second contour section, i.e. the actuating element is (further) driven in the direction of rotation by means of the spring element acting on the slide.

[0024] In particular, the snap angle from which the actuating element continues to rotate under spring drive is determined by the apex of the contour.

[0025] The actuating element preferably has an actuating protrusion, wherein the switching element has a switching pin that is preloaded against the actuating element at least substantially orthogonally to the direction of rotation. The switching pin is triggered by the actuating protrusion when the actuating element is at a switching angle relative to the rotary element.

[0026] Preferably, the switching device is configured to switch the at least one switching element of the socket into a non-conductive state when the plug (along an axial direction of the socket) is removed from the The plug is removed or pushed out of the receiving opening in the unlocked position. This prevents current from flowing through the electrical socket contact, even if a failure occurs in the switching device, for example, due to a failure of the spring element or the slider, when the plug is unplugged.

[0027] Preferably, the switching element is mounted on the rotary element in a rotationally fixed manner, wherein in particular a further switch elevation is arranged in a stationary manner on the socket housing, so that the switching element is actuated when the plug is pushed out of the receiving opening from the unlocking position or is in the off position or at the end point during the rotational movement.

[0038] Figure 1 shows a schematic perspective view of an embodiment of the connector device 10 according to the invention. The connector device 10 is used in particular for the electrical connection of electrical equipment and / or electrical lines, preferably in potentially explosive areas.

[0039] The connector device comprises a plug 11 and a socket 12. The plug 11 comprises a plug housing 13 and at least one electrical plug contact 14 held in an insulated manner in the plug housing 13.

[0040] In Figure 1, the plug 11 has three plug contacts 14. However, the plug 11 can also have only one or any number of plug contacts 14.

[0041] The socket 12 has a socket housing 15 and a switching device 19 with a rotary element 16 which is rotatably mounted relative to the socket housing 15. A receiving opening 18 is formed in the rotary element 16, into which opening the plug 11 can be inserted into an unlocking position along the axial direction A. On a side facing the plug 11, the socket has a flange 17.

[0042] The socket 12 has at least one electrical socket contact 14 ' which is held in an insulating manner in the socket housing and which engages with the electrical plug contact 14 when the plug 14 is inserted into the receiving opening 18 .

[0043] In Figure 1, the socket 12 has three electrical socket contacts 14' corresponding to the electrical plug contacts 14. As with the plug contacts 14, there can be any number of socket contacts 14'. However, it is crucial that the socket contacts 14' are arranged to match the plug contacts 14. When the plug 11 is pushed into the unlocking position, the plug 11 can be rotated in the circumferential direction U relative to the socket housing 15. The rotating element 16 is coupled to the plug 11 in such a way that rotation of the plug 11 is transmitted (synchronously) to the rotating element.

[0044] The switching device 19 also has a switching element 20 and an actuating element 21 , wherein the switching element 20 is designed to switch the at least one socket contact 14 ' from a non - conductive state to a conductive state and vice versa when actuated by the actuating element 21 .

[0045] The actuating element 21 is configured to rotate with the rotation of the rotating element 16 and, upon reaching a snap angle a, to rotate in advance of the rotating element 16 and thereby actuate the switching element 20. The details of the actuating process are explained in detail below, particularly with reference to Figures 3 (a) - (d).

[0046] Figure 2 shows the switching device 19 in a side exploded view. The switching device 19 has a rotary element 16 and an actuating element 21, which is plugged onto the rotary element 16 and actuates the switching element 20 of the switching device 19.

[0047] In the example shown in Figure 2, the actuating element 21 is designed as an annular switching wheel. The actuating element 21 designed as an annular switching wheel has a contour K.

[0048] In addition, the switching device 19 has a slide 22 which is arranged on the socket housing 19 in a rotationally fixed manner such that the slide 22 runs on the contour K and is pretensioned against it by means of the spring element 25. The slide 22 has a running wheel 24 on its underside which contacts the surface of the contour K. The slide 22 is attached to the socket housing 15 at least substantially orthogonally in a rotationally fixed manner to the actuating element 21.

[0049] The switching device 19 also has a locking element 23. The locking element 23 has one or more pins 26 which are parallel to the Extend in the axial direction A toward the actuating element 21. The rotary element 16 has a collar 27 with a plurality of recesses 28. In the installed state, the actuating element 21 sits on the collar 27 such that an annular surface of the actuating element 21 rests on the collar 27. The collar 27 thus forms a running surface for the actuating element 21.

[0050] When installed, the pins 26 of the locking element 23 are pushed through the recesses 28 of the collar 27. The actuating element 21 has one or more recesses 29 into which the pins 26 of the locking element 23 engage when the elements are installed. The recesses 28 in the collar 27 of the rotating element 16 are dimensioned such that rotation in the circumferential direction U is transmitted from the collar 27 to the pins 26 of the locking element 23. The locking element 23 is synchronously coupled for rotation with the rotating element 16.

[0051] The pins 26 then transmit the rotation to the actuating element 21 via the recesses 29. The recesses 29 are dimensioned such that the pins 26 sit in the recess 29 with some play.

[0052] The locking element 23 also has one or more locking pins 30 on the opposite side of the pins 26, which block rotation in the circumferential direction U when the locking element 23 is not arranged in an unlocking position. Further details are explained below with reference to Figures 5(a) and 5(b).

[0053] In Figures 3 (a) - (d) the inventive Concept of the switching device 19 illustrated. Figure 3 (a) shows the movement sequence of the actuating element 21 in relation to the switching element 20 arranged on the rotating element 16 and the socket housing 15. The slide 22 is held on the socket housing 15 by the spring element 25 against the contour K of the actuating element 21 in such a way that the slide 22 follows the contour K of the actuating element 21 when the actuating element 21 rotates relative to the socket housing 15. The slide 22 is resiliently mounted orthogonally to the direction of rotation D by the spring element 25.

[0054] The contour K has a starting point 34 and an end point 36, between which a vertex 35 is arranged. In this example, the contour K is parabolic in shape, so that the lateral flanks are symmetrical to the vertex 35.

[0055] The actuating element 21 also has a recess 29 in which the pin 26, which functions as a driver element, is seated. The recess 29 has a certain amount of play relative to the pin 26 in the direction of rotation D. The recess 29 has a first stop 32 and a second stop 33 for the pin 26.

[0056] Furthermore, the actuating element 21 has an actuating elevation 31 against which the switching pin of the switching element 20 is spring-mounted. The actuating unit 31 has a ramp 31' along which the switching pin of the switching element 20 is guided. In the example shown in Figure 3 (a), the switching pin is shown in an inserted state. In this state, the Switching element 20 is switched to a non-conductive state.

[0057] If the rotating element 16 is now turned by manually turning the plug in the direction of rotation D, the pin 26 rests against the first stop 32, whereby the actuating element 21 is also rotated in the direction of rotation. The slide 22 is fastened to the socket housing 15 in a rotationally fixed manner, so that by rotating the rotating element 16 or the actuating element 21, the slide 22 moves on the contour K. In a first section, the contour K reduces the distance between the actuating element 21 and the socket housing 15, on which the slide 22 is held by the spring element 25. By rotating the rotating element 16 or the actuating element 21, the slide 22 is deflected, wherein the spring element 25 is tensioned.

[0058] In Figure 3 (b), the slide 22 is now located at the apex 35 of the contour K. The spring element 25 is maximally compressed at this point. Upon exceeding the apex 25, the spring element 25 now drives the slide 22, whereby the actuating element 21 is moved relative to the rotary element 16 in the direction of rotation D.

[0059] In Figure 3 (c), the slide 22 is now located on the descending flank of the contour K. In the state shown, the slide 22 has not yet reached the end point 36. In this situation, the actuating element 21 moves in the direction of rotation D relative to the rotary element 16 and thus to the pin 26, which serves as a driver element.

[0060] In Figure 3 (c) the actuating element 21 has been further rotated in the direction of rotation D such that the The shift pin of the switching element 20 is now extended since the actuation elevation 31 has been further shifted in the clockwise direction D. In this state, the switching element 20 is switched to a conducting state. The pin 26 in the recess 29 has not yet reached the second stop 33 of the recess 29 in this state.

[0061] In Figure 3 (d), the slide 22 has now reached the end point 36 of the contour K. The pin 26 has also reached the second stop 33 of the recess 29. The switching element 20 is still switched to a conducting state.

[0062] Figures 4 (a) - (c) illustrate the concept shown in Figures 3 (a) - (d) in a top view. The previously mentioned also applies to Figures 4 (a) - (c) with reference to the reference signs accordingly. The actuating element 21 is seated on the rotating element 16.

[0063] In Figure 4 (a), the rotary element 16 and the actuating element 21 rotate synchronously in the direction of rotation D, since the pin 26 abuts the first stop 32 of the recess 29. The slider 22 is arranged at the starting point 34 of the contour K.

[0064] In Figure 4 (b), the slider 22 has now exceeded the apex 35 of the contour K. This causes the slider 22 to be pressed against the contour K by the spring element 25, pushing the actuating element 21 further. In the example shown in Figure 4 (b), the actuating protrusion 31 has not yet reached the switching element 20.

[0065] In Figure 4 (c), the actuating element 21 has now been rotated further in the direction of rotation D to such an extent that the actuating elevation 31 has now reached the switching element 20, so that the switching element 20 is triggered and the socket contact is switched into a conductive state.

[0066] Figures 5(a) and 5(b) illustrate the operation of the locking element 23. In Figure 5(a), the plug 11 has not yet been inserted into the receiving opening 18 of the socket 12. The locking element is in a position in which the pin sits in a recess of the flange 17. The rotating element 16 cannot be rotated in this position.

[0067] Figure 5(b) now shows an example in which the plug 11 is inserted into the receiving opening 18 of the socket 12. The plug 11 is inserted into the receiving opening 18 so far that it is brought into an unlocking position. In the unlocking position, the locking element 23 is pushed out of the recess in the flange, so that rotation of the plug 11 and, associated with it, rotation of the rotating element 16 in the circumferential direction U is now possible.

[0068] Figure 6 shows the schematic sequence of the switching process of the connector device 10 according to the invention. In the lower diagram in Figure 6, the angle w ' of the actuating element 21 is shown over the angle of rotation w of the rotary element 16. Initially, the actuating element 21 rotates synchronously with the rotary element 16 until the slide 22 reaches the apex 35. This occurs when Snap angle a, at which the actuating element 21 suddenly snaps over. The upper diagram schematically shows the state of the switching element 20. As soon as the snap angle a is reached, the mechanism snaps over and the switching element 20 is switched from a non-conductive state to a conductive state.

[0069] Figure 7 shows the underside of the socket housing 15. In this example, two additional actuating projections 37 are arranged on an inner side of the socket housing 15. These actuate the switching element 20 when the plug 11 is removed from the receiving opening 18. This ensures that the socket 12 is de-energized, even if the switching device 19, such as the spring element 25 or the slide 22, is defective.

[0070] Figure 8 shows a schematic sectional side view of the area in which the further actuating protrusion 37 is formed on the socket housing 15. In the example shown, the rotating element 16 is rotated back into the unlocking position, in which the further actuating protrusion 37 presses onto the switching pin of the switching element 20.

[0071] In Figures 9 (a) - (d) the switching concept of the forced switching off of the socket 12 is illustrated. In Figure 9 (a), the switching element 20 is arranged on the further actuating elevation 37, so that the switching element 20 is switched into a non-conductive state. If the rotary element 16 and thus also the switching element 20 are rotated in the direction of rotation D, the switching element 20 is displaced with respect to the further actuating elevation 37, so that the spring-loaded pin of the switching element 20 extends and switches the switching element into an electrically conductive state. The further actuating elevation 37 has a ramp 37'. In Figures 9 (b) and 9 (c) the switching element 20 is removed from the further actuating elevation 37. Figure 9 (d) now shows the arrangement when the plug 11 and thus also the rotating element 16 are rotated back into the unlocking position. In this position the switching element 20 is now again arranged on the further actuating elevation 37, so that the switching element is switched into a non-conductive state.

[0072] The plug connector device 10 according to the invention has a plug 11 and a socket 12, which has a switching device 19 arranged in a socket housing 15 with a rotary element 16 which is rotatably mounted with respect to the socket housing 15 and in which a receiving opening 18 is formed, into which the plug 11 can be inserted into an unlocking position in such a way that the rotary element 16 can be rotated in the circumferential direction U relative to the socket housing 15 by means of the plug 11.The switching device 19 has a switching element 20 which, when actuated by the actuating element 21, is designed to switch the at least one socket contact 14' from a non-conductive state into a conductive state and vice versa, and an actuating element 21 which is rotationally coupled to the rotating element 16 and is designed to rotate in advance of the rotating element 16 when a snap-over angle a is reached and to actuate the switching element 20. The plug connector device according to the invention serves to switch the socket 12 either into a conductive state or into a non-conductive state. whereby the switching phase between conducting and non-conducting state is kept as short as possible.
