Advantageously, a fixation of the transmission connector device in particular with a cooperating unit, preferably an adapter unit, can be improved and in particular made more secure. Advantageously, a higher user and/or installer comfort can be achieved. Moreover, a transmission connector device can be provided for use in a harsh environment, wherein the provided transmission connector device is in particular capable of handling high requirements of the environment. Advantageously, a high-density population of transmission connector devices wherein a disturbance of the installation and/or uninstallation of the transmission connector device to one another is reduced or avoided, is possible.
The transmission connector device can be part of a transmission connector. The transmission connector device can be a subassembly of the transmission connector or can be embodied as the whole transmission connector. The transmission connector device can be embodied as a data transmission connector device and/or a power transmission connector device. Further, the transmission connector device can be an optical connector device, especially an optical fiber connector device. Preferably, the transmission connector device is a connector device for small, simple and/or multi-fiber fibers. For example, the transmission connector device can be a LC, advantageously a LC-D, SC, MPO and/or MTP connector device.

Alternatively, the cooperating unit could be embodied as a corresponding plug-in component of a device or the likes. Particularly preferably, the cooperating unit is intended for the at least safe and/or secure connection in the harsh environment.
The transmission connector device preferably comprises the latching unit, in particular at least partially and preferably completely. 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.

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 directly. 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 thereby pulls the actuation unit along the axial direction indirectly. Preferably, the actuation unit is configured to be pulled in regard to the cooperating unit for transferring the latching unit from the latch position into the release position, in particular to release the connection between the transmission connector device and the cooperating unit. The transmission connector device is preferably configured to be pushed along the axial direction in regard to the cooperating unit to connect and in particular to latch to the cooperating unit. Preferably, the actuation unit transfers a force by the pulling along the axial direction to the latching unit to transfer the latching unit to the release position. The actuation unit preferably comprises an actuation element. The actuation unit, in particular the actuation element, is preferably implemented as an outer hull and/or sleeve for receiving a portion of the transmission connector device. The actuation unit, in particular the actuation element, is preferably configured to receive the holding unit at least to a great part. The phrasing “to a great part” should in particular be understood in this context to mean, at least 55%, advantageously at least 65%, preferably at least 75%, particularly preferably at least 85% and especially advantageously at most 95% of a volume and/or mass component of an object. The actuation unit can receive the holding unit concentrically around the axial direction.
The locking unit is configured for locking the actuation unit in the locked position, in particular for preventing actuation of the latching unit in the locked position. The locking unit is in particular configured to provide an additional locking mechanism for preventing a movement of the transmission connector device and the cooperating unit relative to each other besides the latching mechanism provided by the latching unit. 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.
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 rotatable, in particular around the axial direction, preferably relative to the actuation unit, for transferring the actuation unit from the locked position to the unlocked position and/or from the unlocked position to the locked position. In particular, the locked and/or unlocked position of the actuation unit relates to a position relative to the operating element, in particular a rotation of the operating element relative to the actuation unit. Preferably, the operating element is intended to be rotated, preferably directly or possibly indirectly, by the user and/or installer, to transfer the actuation unit from the locked position to the unlocked position. In particular, the locking unit is locked in the locked position of the actuation unit and unlocked in the unlocked position of the actuation unit. The locked and unlocked position of the actuation unit corresponds in particular to a locked and unlocked position of the operating element. The operating element is preferably mounted rotatably around at least part of a cable and/or a transmitter and/or a conductor of the cable to be connected by means of the transmission connector device. In particular, the operating element is intended to be rotated by an angle of at least 15°, preferably at least 25°, particularly preferably at least 35° and particularly advantageously at least 45°, in particular improving a comfort to the user and/or a safety.

Advantageously, the angle of rotation can be 35° or 45°. Preferably, the operating element is intended to be contacted by a user and/or installer for actuating the locking unit, in particular at least for unlocking the locking unit.
Preferably, the reset element is intended to transfer at least the actuation unit automatically back from the unlocked position into the locked position, if the operating element is released by the user and/or installer. In particular, the reset element is configured to provide a reset force to transfer the actuation unit from the unlocked position into the locked position. A rotational movement of the operating element relative to the actuation unit can be generated by the reset element. The rotational movement for locking the locking unit is preferably directed in an opposite direction of a rotational movement for unlocking the locking unit. Preferably, the user and/or installer preferably has to apply at least the reset force to the operating element, in particular for the rotation of the operating element, to transfer the actuation unit from the locked position to the unlocked position. In particular, the reset force is generatable by the movement, in particular the rotation, of the operating element to transfer the actuation unit the locked position to the unlocked position.
Preferably, the transmission connector device comprises a holding unit. The holding unit can be intended for holding the latching unit with respect to the axial direction in relation to the actuation unit. Advantageously, a fixation of the latching unit can be improved. The operating element is preferably movably connected to the holding unit in at least one direction. The operating element may be connected to the 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 holding unit. Alternatively, the operating element can only contact the holding unit, without being fixed to the holding unit. In particular, the operating element is rotatable relative to the holding unit. Preferably, the holding unit is formed separately to the actuation unit and/or the operating element and/or can be formed separately to the latching unit and/or the reset element. Preferably, the holing unit is configured to a fixed position cable in the locked and unlocked position. The holding unit is preferably configured to maintain a fixed rotational position around the axial direction in the locked and unlocked position. The holding unit is preferably configured to maintain a fixed rotational position around the axial direction in the locked and unlocked state. The holding unit is preferably configured to maintain a fixed translational position, in particular in regard to the axial direction, relative to the cooperating unit and/or the cable in the locked and unlocked position. The holding unit is preferably unmovably fixed to the cable. Preferably, the holding unit is made in a one-piece embodiment. The holding unit 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. 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. The holding unit is preferably implemented in a cylindrical shape and/or as a sleeve intended to receive at least the cable and/or parts of the cable.
The reset 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 reset element is snapped with the holding unit. Preferably, this fixation between the holding unit and the reset element exists in the locked position and unlocked position of the actuation unit.
Preferably, the locking unit and/or the actuation unit comprise/s a guidance element for guiding the user and/or installer, in particular concerning a movement to be carried out by the user and/or installer, regarding locking and/or unlocking of the actuation unit. Possibly, the locking unit, preferably the guidance element, can comprise arrows for visual guiding the user and/or installer. Alternatively or additionally, the locking unit can be configured to give the user and/or installer an acoustic feedback. Preferably, the guidance element indicates the rotational direction for unlocking the actuation unit. The unlocking of the locking unit is preferably correlated to a one-directional rotation of the operating element, whose direction the guidance element can in particular indicate.
In particular, the transmission connector device is connectable to the cooperating unit by being pushed towards the cooperating unit along the axial direction to engage the latching, in particular by the user and/or installer. Advantageously, no rotational movement carried out by the user and/or installer is necessary to connect the transmission connector device, in particular due to the reset element and the design of the latching unit. The latching is preferably releasable by a rotation of the operating element and a subsequent pulling of at least the actuation unit along the axial direction, in particular by the user and/or installer. Advantageously, a user comfort for the connection of the transmission connector device can be increased, wherein the transmission connector device can in particular be connected especially quickly and/or in a simple manner.
Furthermore, accidental disconnection of the transmission connector device can be advantageously avoided by means of the locking unit.
The axial direction in particular extends at least substantially parallel to and/or along a main extinction axis of the transmission connector device. Preferably, the axial direction extends at least substantially parallel to and/or along a main extension axis of the actuation unit and/or the holding unit and/or the operating element and/or the reset element. By a “main extension axis” of an object is herein in particular an axis to be understood, which extends parallel to a longest edge of a smallest geometric rectangular cuboid that just still completely encloses the object, and in particular runs through the center point of the cuboid. The term “at least 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 of at least the actuation unit along the axial direction.
In this context, “configured” and/or “intended” is to mean specifically programmed, designed and/or equipped. By an object being configured and/or intended for a certain function, it is to be understood that the object fulfills and/or implements this certain function in at least one application state and/or operating state.
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, in particular in the locked position. Thereby, the transmission connector device can be advantageously be prevented from disconnecting from the cooperating unit by means of the locking unit. The relative movement of the actuation unit can be a movement at least substantially parallel to the axial direction. The relative movement is in particular a movement relative to the holding unit and/or cooperating 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 the cable boot unit, which at least partially forms the operating element, a comfort can be improved and/or a compact and/or simple and/or efficient construction of the transmission connector device can be provided. In particular, the cable boot unit is configured for protecting a cable from bending and/or kinking. Preferably, the cable boot unit is mounted rotatably around the axial direction. The locking unit is preferably configured to be unlocked by means of a rotation of the cable boot unit, in particular by means of the user and/or installer. The latching unit is preferably configured to be actuated by pulling of the cable boot unit and thereby the actuation unit along the axial direction, in particular by means of a user operation, and thereby transferring the latching unit from the latch position into the release position. Preferably, the cable boot unit is intended to be contacted by the user and/or installer and can in particular serve as a handle.
The operating element is preferably fixed to the actuation unit with respect to at least one direction, in particular the axial direction. 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 at least one direction, in particular the axial direction. Advantageously, a movement of the cable boot unit and/or the operating element can be effectively transferred to the actuation unit. The operating element, in particular the cable boot unit, is in particular fixed to the actuation unit with respect to the at least one direction in at least the unlocked position and preferably also in the locked position. Preferably, the operating element, in particular the cable boot unit, is unmovably connected to the actuation unit in regard to a translational movement of the operating element and the actuation unit relative to each other, in particular along the axial direction. The operating element, in particular the cable boot unit, can be movably connected to the actuation unit in regard to a rotational movement of the operating element and the actuation unit relative to each other, in particular around the axial direction. The actuation unit can maintain a fixed rotational position for a rotation of the operating element around the axial direction to transfer between the unlocked and locked position. The operating element, in particular 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, in particular at least the actuation element, can comprise at least one counter fit element, which extends at least partially along the circumferential direction of the actuation unit. Preferably, the counter fit element is arranged on an inside of the actuation unit and/or a rest of the actuation unit, in particular on an inside of the actuation element and/or arrest of the actuation element. The operating element, in particular the cable boot unit, preferably comprises at least one fit element, in particular at least one edge, for engaging and/or abutment with the counter fit element. The counter fit element can in particular extend entirely around the circumferential direction. Alternatively, the actuation unit can comprise at least two counter fit elements, which extend only partially along the circumferential direction of the actuation unit. The counter fit element can be bar-shaped and/or implemented as an edge of the actuation unit.
The cable boot unit and/or the operating element can comprise at least one fixating arm. In particular the fixating arm can be configured for at least a fixation with the holding unit. The cable boot unit and/or the operating element can comprise more than one fixating arm, for example two fixating arms, which are in particular implemented identically to each other. Advantageously, the fixating arm is snapped with the holding unit in the locked position. Preferably, part of the fixating arm is received in a fixating recess of the holding unit in the locked position, in particularly in a fixed position, advantageously preventing a relative movement of the cable boot unit and/or operating element, in particular of the fixating arm, along the axial direction relative to the holding unit and/or cable boot unit. The fixating arm is preferably only movable out of the fixating recess by the, in particular one-directional, rotation of the cable boot unit and/or operating element, in particular of the fixating arm, around the axial direction to unlock the locking unit. Preferably, the holding unit has a stopping element, marking an end position, in particular rotational end position, at which the unlocked position is reached. The fixating arm preferably abuts the stopping element in the unlocked position. The holding unit can have at least one guiding channel, which guides the movement of the cable boot unit and/or operating element, in particular the fixating arm. In particular, the fixating arm is received at least partly in the guiding channel. Preferably, the guiding channel extends from the fixating recess to the stopping element in the circumferential direction and in particular in the axial direction, starting from the stopping element. Preferably, the locking unit comprises the fixating recess and/or the stopping element and/or the guiding channel and in particular the fixating arm.
The operating element, in particular the cable boot unit, is preferably unmovably fixed to the holding unit in regard to the translational movement along the axial direction in the fixed position. Preferably, for transferring the actuation unit from the locked position into the unlocked position, the operating element, in particular the cable boot unit, is rotatable around the axial direction, thereby releasing the fixation, in particular in regard to the blocked translational movement along the axial direction, with the holding unit. In an unfixed position the operating element, in particular the cable boot unit, is pullable along the axial direction, in particular relative to the cooperating unit and/or holding unit, for actuating the actuation unit. In at least the unlocked position the fixating arm can contact the counter fit element. Preferably, the fixating arm, in particular an edge of the fixating arm, abuts and/or rests against the counter fit element along the axial direction. In particular, the fixating arm comprises the fit element. The fixating arm is preferably rotatable relative to the actuation unit, in particular the counter fit element. By pulling the cable boot unit, the fixating arm can push against the counter fit element and thereby, the actuation unit can be moved and/or actuated with the cable boot unit along the axial direction.
Preferably, the operating element and/or the cable boot unit are/is used in the locking mechanism and the latching mechanism. The operating element and/or the cable boot unit can be used for transferring the latching unit from the latch position into the release position. Particularly preferably, the operating element is, in particular in the unlocked position, 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. Preferably, a relative movement of the operating element and/or the cable boot along the axial direction relative to the holding unit is prevented in the locked position.
Furthermore, it is proposed that the reset element is an elastic element. Thereby, the reset force of the reset element can be provided in an especially simple and/or efficient and/or reliable manner. Advantageously, the reset force is automatically provided by a deformation of the reset element by means of the user and/or installer. In particular, no further outside energy source is necessary to provide the reset force. Alternatively or additionally, it would be conceivable, that the reset element could for example acquire the reset force at least partly from the user and/or installer and/or a motor and/or hydraulic and/or pneumatic and/or gravitational and/or electric and/or magnetic forces and/or the likes. The reset element could be implemented to be inelastic. An “elastic element” is in particular to be understood as an element which can be repeatedly deformed without the element being mechanically damaged or destroyed and which, in particular, seeks to automatically and/or autonomously return to a basic shape after deformation. In particular, the elastic element is flexible and/or elastic and/or stores mechanical energy. The elastic element can be a spring-elastic element. Preferably, the reset element is in a stressed state in the unlocked position. The reset element is preferably in a relaxed state in the locked position. In particular, the deformed state of the reset element, in particular of the elastic element, corresponds to a stressed state of the reset element. The reset element preferably has the basic shape in a relaxed state. The reset element can be implemented to have rubber-elastic properties and/or be spring-elastic, for example by means of a spiral and/or leaf spring, and/or the likes. In particular, the operating element and/or the cable guard unit is/are elastically connected to the holding unit by means of the reset element.
To improve a construction and/or an efficiency of the reset element, it is proposed, that at least portions of the reset element are rotatable around the axial direction. Thereby, the reset force can be effectively directed in an advantageous direction, in particular by means of a particularly simple and/or compact construction. Preferably, a first end of the reset element is connected to the holding unit, in particular unmovably relative to the holding unit. A second end of the reset element is preferably connected to the operating element, in particular unmovably relative to the operating element. In particular, the first end of the reset element is in a fixed position during operation, in particular rotation, of the operating element. The second end of the reset element is preferably configured to move, in particular rotate, with the operating element. Preferably, the reset element is configured to be transferred from the relaxed state to the stressed state by means of a relative movement between the first and the second end of the reset element for the operation, in particular rotation, of the operating element. In particular, at least the second end of the reset element is rotatable around the axial direction. The reset element is in particular configured to twist the operating element, in particular the cable boot unit, relative to the holding unit.
Preferably, the reset element is configured to be twisted from the relaxed state to the stressed state, in particular a twisted state, for unlocking the locking unit. The reset element is preferably configured to automatically and/or autonomously untwist from the stressed, in particular twisted state, to the relaxed state of the reset element, in particular in absence of outside forces. Advantageously the reset element is configured to untwist for locking the locking unit and in particular to transferring at least the actuation unit back from the unlocked position into the locked position. In particular, the reset element is configured to be twisted and/or to untwist around the axial direction. Furthermore, it is proposed in at least one embodiment of the invention, that the reset element comprises a torsion spring, by which in particular an especially simple and/or effective construction of the reset element can be achieved. The reset element can be formed as the torsion spring. Preferably the relaxed and/or stressed state of the reset element corresponds to a relaxed and/or stressed state of the torsion spring. The reset element, in particular the torsion spring, is preferably cylindrical. Preferably, the reset element comprises and/or is a helical torsion spring. The reset element is preferably configured to be twisted by sideways forces, in particular perpendicular to the axial direction, applied to first and/or second end of the reset element. In particular, a coil of the reset element, in particular the torsion spring, is twisted tighter in the stressed, in particular twisted state, relative to the relaxed state. The reset element, in particular the torsion spring, can have more than two windings. However, preferably, the reset element has less than two windings. Thereby, a length of the transmission connector device can be advantageously shortened, in particular providing a compact construction of the transmission connector device. The transmission connector device can comprise merely one reset element, in particular torsion spring.
Moreover, it is proposed, that the reset element is at least partially made of metal and/or of a wire. Preferably, the reset element is, in particularly at least partially, made of a metal wire. Thereby, a resistance and/or a durability of the reset element and in particular the transmission connector device can be improved for use in a harsh environment. Advantageously, a temperature resistance, in particular at least a heat resistance, can be improved. Furthermore, the reset element and in particular the transmission connector device can be constructed to be advantageously compact, in particular reducing possible lateral forces of the reset element. Alternatively of additionally, the reset element can at least partially be made of a different material than metal, for example plastic and/or a mineral and/or carbon fiber and/or rubber and/or the likes. Moreover, a cost efficiency can be advantageously improved.
To improve a construction, it is proposed that the wire has a diameter of maximally 5 mm. Preferably, the wire has a diameter of maximally 4 mm, advantageously of maximally 3 mm, particularly preferred of at most 2 mm, advantageously preferred of maximally 1 mm and/or of minimally 0.1 mm, particularly preferred of at least 0.5 mm and advantageously preferred of minimally 0.7 mm. The wire can have a diameter of at least substantially 0.8 mm, wherein the wire diameter deviates in particular less than 25%, preferably less than 10% and particularly preferably less than 5% from 0.8 mm. Thereby, a reset element with advantageous reset forces and/or a particularly compact design and/or cost efficiency can be achieved. The reset element can be formed separately from the locking unit, in particular the operating element. Preferably, the reset element formed as a torsion spring and/or made of metal and/or a wire, is formed separately from the locking unit, in particular the operating element. Thereby, a construction of the reset element can be simplified and/or a flexibility, in particular regarding a material choice and/or shape of the reset element, can be increased.
Alternatively, in particular in another possible embodiment of the invention, it is proposed that the reset element is implemented integrally with at least part of the locking unit. In particular, the reset element is implemented integrally with the operating element. Advantageously, a production efficiency can be improved and/or a compact design can be achieved. In particular, the reset element can be fixed to the operating element in a particular efficient and/or reliable manner. Furthermore, a number of separate parts for assembly of the transmission connector device can be advantageously decreased, decreasing a complexity of the transmission connector device. “Implemented integrally” is in particular 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 multicomponent injection molding procedure, and advantageously from a single blank. Preferably, the reset element is formed in one piece with at least part of the locking unit, in particular the operating element. The reset element can be made of a same material as the operating element, in particular a material with sufficient elastic properties, such as a plastic and/or metal.
Furthermore, it is proposed, that the reset element comprises an arm-shaped element, by which in particular an advantageous effective reset force of the reset element can be achieved in a particularly compact and/or simple manner. The reset element can be formed as the arm-shaped element. The reset element, in particular the arm-shaped element, can advantageously be implemented integrally with the operating element. In particular, the reset element can be implemented differently from a spring. The arm-shaped element is in particular elongate and/or has an in particular curved and/or angled longitudinal extent which is in particular larger by a factor of at least 2 than at least one transverse extent, in particular every transverse extent, that is at least substantially perpendicular in relation to the longitudinal extent. The term “at least substantially perpendicularly” is here in particular to mean an orientation of a direction relative to a reference direction, wherein the direction and the reference direction, in particular viewed in a projection plane, include a 90° angle and the angle has a maximum deviation of in particular less than 8°, advantageously less than 5° and especially advantageously less than 2°. The transmission connector device can comprise more than reset elements, in particular arm-shaped elements, which are preferably implemented identically to one another. The reset elements can be formed separately from each other or are preferably implemented integrally with each other. Preferably, the transmission connector device comprises two reset elements, in particular arm-shaped elements. The reset elements, in particular the arm-shaped elements, are preferably symmetrically arranged around the axial direction in at least a mounted state of the transmission connector device. Alternatively, the reset elements can be arranged asymmetrically around the axial direction and/or comprise a different symmetry. A first end of the arm-shaped element is preferably latched and/or snapped and/or fixed to the holding unit. The first end of the arm-shaped element could be implemented integrally with the holding unit. A second end of the arm-shaped element is preferably connected, in particular unmovably connected relative to the operating element, and/or fixed to and/or implemented integrally with the operating element and/or the cable boot unit. In particular, the first end of the arm-shaped element is in a fixed position, in particular in the unlocked and locked position, while the second end of the arm-shaped element is intended, in particular fixated, to move with the operating element. The arm-shaped element is preferably configured to be bent from the relaxed state of the reset element to the stressed state of the reset element. The elongate direction of the arm-shaped element can be at least substantially parallel to the axial direction, in particular at least in the locked position of the actuation unit and/or the relaxed state of the reset element. Preferably, the relaxed and/or stressed state of the reset element corresponds to a relaxed and/or stressed state of the arm-shaped element. Preferably, the arm-shaped element is implemented to bend in the radial direction and in particular a transverse direction of the arm-shaped element.
