By means of the invention an enhanced fixation and releasement mechanism, construction and/or a higher comfort can be achieved. Preferably, a flexible mechanism for fixing and for releasing a transmission connector device can be achieved.

Moreover, a compact design can be achieved. This allows achieving a particularly user-friendly and easy-to use latching unit which can be preferably latched and released without additional tools. Due to a spring element the latching unit can be quickly and easily released. Additionally, the latching unit can also be quickly and easily latched. Furthermore, a handling can be simplified. In addition, a fixation of the transmission connector device in particular with a cooperating unit, preferably an adapter unit, can be optimized and made more secure.

In particular, the latching unit is configured to provide a latching mechanism. Advantageously, the latching unit is configured for a reversible, preferably non-destructive, releasing and/or latching. In this context, the “latch position” is to be understood as a position, in which the latching unit latches the transmission connector device with the cooperating unit. In particular, if the latching unit is in the latch position, the transmission connector device is in a connected position with the cooperating unit. Under a “release position” a position is to be understood, in this context, in which the latch between the transmission connector device and the cooperating unit is released. In particular, in the release position the latching unit is deformed so that the latch is released.
By “pulling the actuation unit along the axial direction” can be understood that a user and/or installer pulls the actuation unit itself along the axial direction. Alternatively, and preferably in this context, it should be understood that the user and/or installer pulls another unit and/or element of the transmission connector device which is connected to the actuation unit and pulls thereby the actuation unit along the axial direction.

The at least partially ring-shaped spring element is to be understood, in this context, as an elastic element that stores mechanical energy. In the present case, the “spring element” is an element which can be repeatedly deformed without the element being mechanically damaged or destroyed and which, in particular, automatically returns to a basic shape after deformation. In particular, the spring element is flexible and/or elastic. Advantageously, the spring element is an elastic, in particular a spring-elastic, element.

Preferably, the spring element is made in a one-piece embodiment. By “made in a one-piece embodiment” is to mean, connected at least by substance-to-substance bond, for example by a welding process, a gluing process, an injection-molding process, and/or another process that is deemed expedient by someone skilled in the art and/or advantageously formed in one piece, like for example by a production from a cast and/or by a production in a one-component or multi-component injection-molding procedure, and advantageously from a single blank. In particular, the spring element is symmetrical with respect to a symmetry plane. It can be possible, that the wire clip is closed.
Advantageously, the spring element is embodied as a C-shaped wire clip. Thereby, a compact, narrow and/or efficient construction and/or design of at least a spring element, in particular a latching unit, can be further provided. Moreover, a handling can be optimized. Since, the proposed C-shape wire clip has only one opening, a user-friendly and easy-to use latching unit can be achieved, which can be preferably latched and released without additional tools. Furthermore, an efficient, in terms of product and/or manufacturing and/or cost efficiency, can be increased.

Moreover, it is proposed, that the actuation unit comprises at least one channel, in which the latching unit is partially arranged, and an actuation element, which at least partially delimits the channel. In this way, a connection, preferably a fixation, of a latching unit with an actuation element can be optimized. In addition, an unintentional detachment of the latching unit in particular from at least the actuation unit can be prevented.

Advantageously, in circumferential direction of the actuation unit the channel and the holding unit are arranged side-by-side. Preferably, in the circumferential direction of the actuation unit the channels and the holding unit are arranged in alternation. In the circumferential direction of the actuation unit there can be at least two areas, preferably at least three areas, in which the holding unit holds the latching unit with respect to the axial direction. In particular, the three channels and the holding unit are arranged in alternation.
Further, the three channels and the three areas can be arranged in alternation in the circumferential direction of the actuation unit.
In a preferred implementation of the invention, it is proposed that the actuating unit comprises at least one guiding element which is configured to stretch the latching unit by pulling the actuation unit. In this way, a simple and efficient releasing of a latching unit can be provided. Further, this allows achieving a particularly user-friendly and easy-to use latching unit which can be released without additional tools. Thereby, a comfort for a user and/or installer can be optimized.
Preferably, the latching unit is stretchable without additional tools. The guiding element can be configured for stretching the latching unit and growing a diameter of the latching unit for the at least 5%, in particular at least 10% and advantageously at least 20%.
Additionally, it is proposed that the guiding element is movable at least partially under the latching unit by pulling the actuating unit. In this way, a releasement mechanism can be further improved, wherein a simple and efficient releasing of a latching unit can be provided. Furthermore, a handling can be simplified. Moreover, a compact design can be achieved.
In particular by pulling the actuation unit the guiding element is movable at least partially under the latching unit and thereby stretches the latching unit, in particular the spring element. By stretching the latching unit, the connection between the transmission connector device and the cooperating can be released. Preferably, in the release position the latching unit is at least partially stretched. Particularly preferably, in the release position the guiding element is at least partially arranged under the latching unit. The actuation element and/or the guiding element can be made at least partially or to a great part or completely from a mineral and/or a metal and/or preferably a plastic.

For the purpose of improving a compact design and/or fixation of a latching unit, it is proposed that the guiding element at least partially delimits the channel. The guiding element can be configured for holding the latching unit in the channel at least in the latch position. Advantageously, the guiding element and the actuation element hold the latching unit, in particular the spring element, in the channel at least in sections on opposite sides of the latching unit. In particular, the actuation element and the guiding element are arranged on opposite sides of the channel for delimiting the channel. The actuating unit can comprise more than one guiding element, namely at least two guiding elements. Preferably, the actuating unit comprises at least three guiding elements. The actuating unit can have as many guiding elements as it comprises channels.
In another aspect of the invention, which can in particular be considered in combination with as well as separately from other aspects of the invention, it is proposed that the transmission connector device comprises a looking unit for locking the actuation unit in a locked position and for preventing actuation of the actuation unit in the locked position. In this way, a fixation mechanism and a construction can be improved. Due to a locking unit a locking mechanism additional to a latching mechanism provided by a latching unit can be provided. Further a security and thereby, a comfort can be increased. Additionally, a secure connection between a transmission connector device and at least a cooperating unit, preferably an adapter unit, and/or a further transmission connector device can be achieved. Moreover, a transmission connector device can be provided for use in a harsh environment, wherein the provided transmission connector device is capable of handling the high requirements in the environment.

In particular, the locking mechanism is configured for supporting the latching mechanism, preferably if the latching unit is in the latch position and the actuation unit is in the locked position. The locking unit can lock the actuation unit when the transmission connector device is in the connected position with the cooperating unit. The locking unit can lock the actuation unit when the latching unit is in the latch position. Preferably, the locking unit is operable without additional tools.
For the purpose of improving a fixation and/or locking, it is proposed that the locking unit prevents a relative movement of the actuation unit along the axial direction. The relative movement of the actuation unit can be a movement substantially parallel to the axial direction. The term “substantially parallel” is to mean an orientation of a direction relative to a reference direction, in particular the axial direction, wherein the direction relative to the reference direction has a deviation smaller than 8°, advantageously smaller than 5° and especially advantageously smaller than 2°. In particular, the locking unit prevents pulling at least the actuation unit along the axial direction. Additionally, the locking unit can prevent a rotating of at least the actuation unit. The locking unit can also prevent a relative movement of further elements and/or units of the transmission connector device along the axial direction.
Preferably, the locking unit comprises an operating element which is rotatable for transferring the actuation unit from the locked position into an unlocked position. Thereby, a particularly user-friendly and easy-handling unlocking of at least an actuation unit can be achieved. Due to an operating element the actuation unit can be preferably locked and unlocked without additional tools. In that way, a comfort can be improved and/or a compact and/or efficient construction of a transmission connector device can be provided.
By operating the operating element at least one further element of the transmission connector device can be moved and/or actuated and/or operated. Preferably, the operating element is used in the locking mechanism and the latching mechanism. The operating element can be used for transferring the latching unit from the latch position into the release position. Particularly preferably, the operating element is pullable along the axial direction for actuating, preferably for pulling, the actuation unit. By pulling the operating element along the axial direction, the actuation unit can also be movable and/or actuated along the axial direction.
For improving a releasement mechanism and a construction, it is proposed that in the locked position the operating element is connected to the holding unit with respect to the axial direction. Thereby, an improved interaction between an operating element and a holding unit, and preferably an actuation unit, can be achieved. Moreover, the releasement mechanism and advantageously a fixation mechanism can be simplified and made more user-friendly. Furthermore, a higher comfort can be achieved.
The operating element may be connected to holding unit by a force-fit and/or form-fit and/or adhesive-bond connection. The operating element can be fixed to the holding unit. For example, the operating element can be latched and/or snapped with the holing unit. Alternatively, the operating element can only contact the holding unit, without being fixed to the holding unit.
In one possible embodiment of the invention, it is proposed that the transmission connector device comprises a cable boot unit, which at least partially forms the operating element. Thereby, a particularly user-friendly and easy-handling locking and/or unlocking of at least an actuation unit can be achieved. Due to a cable boot unit which at least partially forms an operating element, a comfort can be improved and/or a compact and/or simple and/or efficient construction of a transmission connector device can be provided. In particular, the cable boot unit is configured for protecting a cable from bending and/or kinking.
For the purpose of improving a construction and/or a fixation and/or releasement mechanism, it is proposed that the cable boot unit is fixed to the actuation unit with respect to the axial direction, in particular in at least the unlocked position. The cable boot unit can be fixed to the actuation unit by a force-fit and/or form-fit and/or adhesive-bond connection. The actuation unit can comprise at least one bar-shaped element, which extends only partially along the circumferential direction of the actuation unit. The bar-shaped element can extend for at least 5%, in particular for at least 10%, and advantageously at least 20% along the circumferential direction of the actuation unit. Preferably, the actuation unit comprises at least two bar-shaped elements, which extend only partially along the circumferential direction of the actuation unit. Particularly preferably, the actuation element comprises at least the bar-shaped element.
The cable boot unit can be fixed to the holding unit by a force-fit and/or form-fit and/or adhesive-bond connection. Preferably, the cable boot unit is snapped with the holding unit, in particular for locking the actuation unit. The cable boot unit can comprise at least one fixating arm. In particular the fixating arm can be configured for at least a fixation with the holding unit. Advantageously, the fixating arm is snapped with the holding unit in the locked position.
For transferring the actuation unit from the locked position into the unlocked position the cable boot unit can be rotatable and thereby, releasing a fixation with the folding unit. The cable boot unit can be fixed to the holding unit in a fixed position. In an unfixed position the cable boot unit can be pullable along the axial direction for actuating the actuation unit. In at least the unlocked position the fixating arm can contact the bar-shaped element. In particular, the fixating arm rests against the bar-shaped element viewed along the axial direction. By pulling the cable boot unit, the fixating arm can push against the bar-shaped element and thereby the actuation unit can be moved and/or actuated also along the axial direction.
Further, it is proposed that the transmission connector device comprises an elastic element for preferably automatically transferring back at least the actuation unit from the unlocked position into the locked position. Thereby, a high comfort can be provided. Moreover, a particularly user-friendly and easy-handling construction for locking and unlocking of at least an actuation unit can be achieved. Furthermore, an automatic locking mechanism can be provided. Due to the spring element at least the actuation unit can be locked without additional tools. In that way, a compact and/or efficient construction of a transmission connector device can be provided.
In particular, if the operating element, preferably the cable boot unit, is released by the user and/or installer, due to the elastic element at least the actuation is preferably automatically transferred back from the unlocked position into the locked position. The spring element can be stretchable, in particular if the operating element is pulled along the axial direction. The elastic element can be connected, in particular fixed, to the holding unit by a force-fit and/or form-fit and/or adhesive-bond connection. Advantageously, the elastic element is snapped with the holding unit. Preferably, this fixation between the holding unit and the elastic element exists in the locked position and unlocked position of the actuation unit.
Furthermore, it is also proposed that the elastic element is also configured for preferably automatically transferring the latching unit into a rest position. By such a design/construction of a locking unit, preferably an elastic element, an efficiency and/or a comfort can be further increased. Thereby, a high comfort can be provided. Moreover, a particularly user-friendly and easy-handling construction for locking and unlocking of at least an actuation unit can be achieved. Preferably, the latching unit is in the rest position in a same position/orientation as in the latch position relative to the actuation unit, wherein in particular the latching unit is free of contact with the cooperation unit in the rest position. In particular, after pulling the operating element along the axial direction the user and/or installer can unhand the operating element and due to the spring element, the actuation unit and/or the latching unit is automatically transferred back.
In another possible embodiment of the invention, it is proposed that the actuation unit comprises at least one abutment element, which in the locked position abuts against the operating element thereby preventing actuation of the actuation unit. Thereby, a simple, efficient and/or compact construction can be provided. Furthermore, a fixation mechanism, preferably a locking mechanism, can be improved. The actuating element and the abutment element can be made in a one-piece embodiment. The actuation unit can have more than one abutment element. Preferably the actuation unit comprises at least two abutment elements.
Moreover, it is proposed that the abutment element is embodied as an annex which extends only partially along a circumferential direction of the actuation unit. In that way, a compact and/or efficient construction of a transmission connector device can be provided. In particular, by the circumferential direction of the actuation unit is meant the previously mentioned circumferential direction of the actuation unit. The abutment element that is embodied as an annex can extend for at least 5%, in particular for at least 10%, and advantageously at least 20% along the circumferential direction of the actuation unit. Preferably, the abutment element extends over at most 40%, in particular at most 50%, along the circumferential direction of the actuation unit.
For improving a releasement mechanism, preferably an unlocking mechanism, and/or a handling for a user and/or installer, it is proposed that the locking unit comprises at least one recess, into which the abutment element is moveable when actuating the actuation unit. In that case, the user and/or installer can pull the actuation unit itself, in particular which is in the unlocked position, along the axial direction for transferring the latching unit of the transmission connector device from a latch position into a release position. In the unlocked position by pulling the actuation unit along the axial direction, the abutment element is movable into the recess.

The connecting unit 52a is embodied as an adapter unit and is configured for connecting the transmission connector device 12a with at least one further transmission connector device 70a (cf.
For latching with the cooperating unit 52a the transmission connector device 12a comprises a latching unit 18a. Further, the transmission connector device 12a comprises an actuation unit 16a for actuating the latching unit 18a by pulling along an axial direction and thereby transferring the latching unit 18a from a latch position into a release position. In this context, the latch position is to be understood as a position, in which the latching unit 18a latches the transmission connector device 12a with the cooperating unit 52a (cf.
In
The transmission connector device 12a comprises a holding unit 23a for holding the latching unit 18a with respect to the axial direction 20a in relation to the actuation unit 16a. For better understanding
The holding unit 23a is configured for holding the latching unit 18a on one side opposite to the actuation unit 16a. The holding unit 23a and the actuation unit 16a hold the latching unit 18a at least in sections on opposite sides of the latching unit 18a (cf.
Furthermore, the actuation unit 16a comprises at least one channel 26a, in which the latching unit 18a is partially arranged, and an actuation element 35a, which at least partially delimits the channel 26a. In the present case, the actuation unit 16a comprises at least three channels 26a in a circumferential direction of the actuation unit 16a. The channels 26a are embodied identical to each other. The holding unit 23a and the actuation element 35a hold the latching unit 18a, namely the spring element 21a, at least in sections on opposite sides of the latching unit 18a.
The actuating unit 16a comprises at least one guiding element 28a which is configured to stretch the latching unit 18a by pulling the actuation unit 16a. In this exemplary case, the actuating unit 16a comprises at least three guiding elements 28a. The guiding element 28a at least partially delimits the channel 26a. The guiding element 28a is configured for holding the latching unit 18a in the channel 26a at least in the latch position. The guiding element 28a and the actuation element 35a hold the latching unit 18a, namely the spring element 21a, in the channel 26a at least in sections on opposite sides of the latching unit 18a. The actuation element 35a and the guiding element 28a are arranged on opposite sides of the channel 26a for delimiting the channel 26a (cf.
For locking the actuation unit 16a in a locked position and for preventing actuation of the actuation unit 16a in the locked position, the transmission connector device comprises a locking unit 30a. The locking unit 30a prevents a relative movement of the actuation unit 16a along the axial direction 20a. For transferring the actuation unit 16a from the locked position unit into an unlocked position the locking unit 30a comprises an operating element 32a which is rotatable. The transmission connector device 12a comprises a cable boot unit 36a. In this exemplary embodiment the cable boot unit 36a forms at least partially the operating element 32a (cf.
In the following the releasement mechanism for releasing the connection between the transmission connector device 12a and the cooperating unit 52a should be explained more in detail.
In
First, for transferring the actuation unit 16a from the locked position into the unlocked position the operating element 32a, in this case the cable boot unit 36a, is rotatable (cf.
For transferring the latching unit 18a from the latch position into the release position the actuation unit 16a has to be pulled along the axial direction 20a. By the expression, “pulling the actuation unit 16a along the axial direction 20a” can be understood that the user and/or installer pulls the actuation unit 16a itself along the axial direction 20a. In this present case, it should be understood that the user and/or installer pulls another unit and/or element of the transmission connector device 12a which is connected to the actuation unit 16a and pulls thereby the actuation unit 16a along the axial direction 20a. In this exemplary embodiment, the user and/or installer should pull the operating element 32a, namely the cable boot unit 36a. Due to the connection of the operating element 32a with the holding unit 23a and/or the actuation unit 16a, pulling the operating element 32a along the axial direction 20a causes the actuation unit 16a to be pulled.
The actuation unit 16a, namely the actuation element 35a has at least one bar-shaped element 56a, which extends only partially along the circumferential direction of the actuation unit 16a. In this case, the actuation unit 16a hast at least two bar-shaped elements 56a. In at least the unlocked position the fixating arm 38a contacts the bar-shaped element 56a. The fixating arm 38a rests against the bar-shaped element 56a viewed along the axial direction 20a. By pulling the cable boot unit 36a, the fixating arm 38a is pushing against the bar-shaped element 56a and thereby the actuation unit 16a can be moved and/or actuated also along the axial direction 20a. By means of arrows the direction of movement for transferring the latching unit 18a into the release position of the latching unit 18a is schematically shown in
In the release position the latching unit 18a is deformed so that the latch is released. For stretching the latching unit 18a the guiding element 28a is movable at least partially under the latching unit 18a by pulling the actuating unit 16a. If the latching unit 18a is in the released position the transmission connector device 12a can be completely disconnected from the cooperating unit 52a, namely by pulling the operating element 32a along the axial direction 20a.
After a disconnection between the transmission connector device 12a and the cooperating unit 52a, the elastic element 60a is configured for automatically transferring back at least the actuation unit 16a from the unlocked position into the locked position. Further, the elastic element 60a is also configured for automatically transferring the latching unit 18a into a rest position.
The actuation unit 16b comprises at least one abutment element 66b, which in the locked position abuts against the operating element 32b thereby preventing actuation of the actuation unit 16b. In this present embodiment, an actuation element 35b of the actuation unit comprises the abutment element 66b. The abutment element 66b is embodied as an annex 68b which extends only partially along a circumferential direction of the actuation unit 16b.
The locking unit 30b comprises at least one recess 72b, into which the abutment element 66b is moveable when actuating the operating element 32b. In this present embodiment, the actuation unit 16b has to be pulled along the axial direction 20b. A user and/or installer can pull the actuation unit 16b itself along the axial direction 20b for transferring a latching unit 18b of the transmission connector device 12b from a latch position into a release position. By pulling the actuation unit 16b, namely the actuation element 35b, the abutment element 66b is movable into the recess 72b. In this present exemplary embodiment b, in contradiction to embodiment a, there is no spring element for automatically transferring back at least the actuation unit from the unlocked position into the locked position.
The locking unit 30b comprises a guidance element 74b for guiding the user and/or installer regarding locking and/or unlocking of the actuation unit 16b (cf.
