Description

Technical Field

[0001] This invention relates to a plug-in connector device for optical signal lines. Background Technology

[0002] Optical signal lines, such as fiber optic lines, have been used for decades to transmit large signals and data volumes. With digitization and automation, and the resulting increase in data demands, optical signal lines are finding increasing application in fields long dominated by electrical signal lines. This is primarily because it is becoming increasingly difficult to provide the required transmission volumes using electrical signal lines. However, as optical signal lines are introduced into new application areas, the requirements for optical signal lines and their connector systems are changing, whereby the optical signal lines can connect to these connector systems. Correspondingly, there is a growing demand for economical connector systems for optical signal lines that are resistant to environmental influences and mechanical loads that can be applied to the connector during or while it is in the mating state.

[0003] In particular, there is a requirement for the plug connector on the cable side: that is, even when tension is applied to the plug connector or the cable, a reliable optical signal connection is maintained between the plug connector and the mating plug connector connected to the plug connector. Summary of the Invention

[0004] Therefore, the object of the present invention is to provide a plug connector device that ensures resistance to mechanical loads and reliable signal connection.

[0005] The objective of the invention is achieved by a plug connector device having the features of the independent claims; further advantageous designs of the invention can be derived from the dependent claims, the specification and the drawings.

[0006] The plug connector device according to the invention comprises a plug connector housing, a cable, a fixing unit, a damping unit, and a contact unit. The plug connector housing is capable of being connected to a mating plug connector at the plug side. The cable has at least one optical waveguide surrounded by a cable sheath. Here, it is particularly preferred that the fixing unit is connected to the cable sheath in a material-fitting and / or form-fitting manner. The damping unit is arranged within the plug connector housing. The contact unit has at least one contact side. The contact side can be understood as the side where the contact unit can be connected to the mating plug connector in a signal-conductive manner. The optical waveguide extends from the cable sheath at the cable end. The damping unit has a receiving space in which the contact unit is arranged at least segmentally. The optical waveguide extends through the contact unit to the contact side. The optical waveguide is capable of being connected to the mating plug connector in a signal-conductive manner at the contact side. Therefore, it is preferred that the contact side is formed by the contact unit and by the optical waveguide. The fixing unit has at least one first locking element. This first locking element is connected to a first mating locking element at the plug connector housing. At least one first elastic element is arranged between the damping unit and the fixing unit. This elastic element pre-biases the damping unit against the stop surface of the connector housing towards the mating side. Preferably, the elastic element acts parallel to the mating axis, such that the damping unit is also pre-biased against the stop surface parallel to the mating axis. The mating axis can be understood as an imaginary axis along which the connector assembly moves to connect with a mating connector. The contact unit is supported within the connector housing by a spring-elastic support element. Alternatively or additionally, the contact unit is supported within a receiving space by a support element. By supporting the contact unit with the support element, the contact unit can move radially relative to the damping element and / or the connector housing about the mating axis. The support element is configured to hold the contact unit in an initial position and, when the contact unit moves radially about the mating axis from the initial position, apply a force to return the contact unit to the initial position. In this paper, the initial position can be understood as the position or orientation of the contact unit supported by the support element when no force is applied to the contact unit.

[0007] The plug connector device according to the invention achieves a secure and load-bearing connection of an optical waveguide to a mating plug connector, which is compatible with the plug connector device according to the invention. Because the fixing unit is connected to the cable at the cable end and to the plug connector, the tensile force acting on the cable can be discharged through the plug connector housing. Furthermore, by pre-biasing the damping unit against the stop surface using an elastic element, it is ensured that the optical waveguide and the contact unit are always positioned in a defined manner. Moreover, after connecting the plug connector device to the mating plug connector, it is ensured that the unit, and thus the optical waveguide, is pressed against the plug connector by the first elastic element of the damping unit. Therefore, even if the plug connector device is subjected to a large load (e.g., vibration or flutter), a reliable, signal-conducting optical connection is ensured. Furthermore, during assembly, an easily operable sub-assembly consisting of a contact unit, a damping unit, and a fixing unit can be formed. Therefore, installation in the plug connector housing is feasible without the risk of damaging the optical waveguide. By supporting the contact unit within the connector housing or within the receiving space of the damping unit, the contact unit is supported in a floating manner within the connector housing or the receiving space of the damping unit. Therefore, especially when connecting the connector assembly according to the invention with a mating connector, lateral forces, for example, can be avoided acting on the contact unit. This avoids the risk of damage. For example, such lateral forces often occur if the connector is not properly connected to the mating connector parallel to the mating axis, but rather at an angle to the mating axis. By using a support element to return the contact unit to its initial position, it is ensured that the contact unit remains correctly positioned throughout multiple mating processes.

[0008] The contact unit may have at least one collar housing. Furthermore, the contact unit may have at least one contact collar supported within the collar housing. In this case, it is preferable that the contact side is arranged at the contact collar. The contact collar may extend partially, particularly parallel to the insertion axis, from the collar housing. Preferably, the contact collar is radially movable within the contact unit along the insertion axis. In this way, additional floating support for the contact collar within the contact unit can be provided. If the cable has multiple optical waveguides, it is preferable that the contact collar, each with one contact side, is associated with each optical waveguide.

[0009] The contact ferrule is movable relative to the ferrule housing parallel to the mating axis. If the contact ferrule is ejected from the ferrule housing, it is particularly preferable that the contact ferrule can be pushed into the ferrule housing. The contact ferrule is additionally pre-biased against the ferrule housing wall by a second elastic element. The ferrule housing wall is preferably located at the end of the ferrule housing opposite to the damping unit. The second elastic element is preferably parallel to the mating axis and acts in the mating direction. Here, the mating direction can be understood as the direction of movement in which the mating connector assembly moves relative to the mating connector when connected to the mating connector.

[0010] The contact ring can be restricted in its movement path by a stop element opposite to the insertion direction. Therefore, it is possible to prevent the contact ring from being pushed too deeply into the contact unit and becoming damaged. For example, when the contact ring moves opposite to the insertion direction, thus preventing further movement in that direction, the movement path of the contact ring can be restricted by the contact ring abutting against the stop element.

[0011] The stop element can be detachably connected to the contact ring housing. This allows for easy installation and removal of the contact ring within the contact unit. Furthermore, this method allows for the replacement of, for example, damaged contact rings or damaged second elastic elements, while both the contact unit and the stop element remain usable. The removable connection between the stop element and the contact unit can be achieved, for example, via a snap-fit ​​connection.

[0012] A second elastic element can be disposed between the stop element and the contact ring. For this purpose, the contact ring can have a flange, against which the second elastic element abuts. The contact ring is preferably partially surrounded by the elastic element. Furthermore, it is preferable that the flange is pre-biased against the ring housing wall by the second elastic element.

[0013] The contact unit can be supported by at least three support elements within the connector housing and / or receiving space. These support elements are arranged around the mating axis. Thus, only a few support elements are needed to ensure that the contact unit can move radially evenly along the mating axis and reliably return to its starting position by the support elements. Three support elements are particularly advantageous when the contact unit is cylindrical. In this case, the support elements are preferably distributed at equal angular intervals around the mating axis. If the cross-sectional shape of the contact unit is not cylindrical, especially if it is mirror-symmetrical, the contact unit can be supported by four or more support elements. In this case, the support elements can be arranged mirror-symmetrically, with their plane of symmetry preferably parallel to the mating axis.

[0014] At least a portion of the support element can be formed by a first spring. The first spring can be arranged at the damping unit. Furthermore, the first spring can extend into the receiving space and abut against the contact unit. The first spring can be integrally formed with the damping unit. Advantageously, the damping unit and the first spring are made of thermoplastic. In this case, the elastic properties of the plastic can be utilized to generate the spring action of the first spring.

[0015] At least a portion of the support element can be formed by a second spring. The second spring can be arranged at the contact unit. Furthermore, the second spring can abut against the housing wall of the connector housing and / or the inner wall of the receiving space. The second spring can be integrally formed with the contact unit. Furthermore, it is preferred that the contact unit is preferably made of thermoplastic. The second spring preferably extends away from the contact unit. In a particular embodiment of the invention, the damping unit has a first spring extending into the receiving space and abutting against the contact unit, wherein the contact unit has a second spring abutting against the housing wall.

[0016] The contact unit can be detachably connected to the damping unit. For example, the contact unit and the damping unit can be interconnected via a snap-fit ​​connection. This not only facilitates easy placement of the contact unit in the receiving space and subsequent connection of the contact unit to the damping unit, but also allows the contact unit to be detached from the damping unit without damage. Preferably, the contact unit and the damping unit are detachably interconnected within the receiving space.

[0017] The damping unit can be fixed to the contact unit in parallel with the insertion axis along the direction of movement. For example, it can be fixed via a detachable connection between the damping unit and the contact unit.

[0018] The damping unit can have at least one second locking element. This second locking element can connect to a second mating locking element at the connector housing. This second locking element can be integrally formed with the damping unit. Therefore, the damping unit can be easily installed in the connector housing and secured in place. Simultaneously, since the damping unit is connected to the fixing unit only via an elastic element, the damping unit and the fixing unit remain essentially mechanically separated.

[0019] The first elastic element can be integrally formed with the damping unit. In this case, the spring action of the first elastic element is preferably generated by the elastic properties of the material forming the damping unit or the first elastic element. For example, the damping unit can be made of thermoplastic. Therefore, apart from the shape of the elastic element, the spring force of the elastic element is essentially determined by the elastic properties of the selected thermoplastic.

[0020] The optical waveguide can move relative to the cable sheath along its longitudinal direction. In other words, the optical waveguide can be floated relative to the cable sheath. In this paper, the longitudinal direction can be understood as the longest extension direction of the optical waveguide. Because the optical waveguide is floated relative to the cable sheath, the tensile force acting on the cable sheath is not transmitted to the optical waveguide.

[0021] The cable can have a support sleeve at its end. This support sleeve can be positioned between the optical waveguide and the cable sheath. The support sleeve can be pushed into the cable sheath at the cable end, wherein the support sleeve surrounds the optical waveguide. The support sleeve is preferably made of metal. The support sleeve can be segmentally surrounded by fixing units. Particularly preferably, the support sleeve is secured to the cable end by the fixing units. For example, the support sleeve ensures that the optical waveguide is not damaged when the fixing units are connected to the cable. Furthermore, if the fixing units are made of injection-molded components, the support sleeve ensures that the plastic substrate does not reach the optical waveguide.

[0022] The support sleeve may have a flange at the end opposite to the cable sheath. This flange is preferably funnel-shaped. The flange preferably extends away from the optical waveguide. This flange ensures that the optical waveguide is not damaged at the edge of the support sleeve.

[0023] The support sleeve can extend through the inlet opening into the intermediate space of the damping unit. A flange can be arranged in the intermediate space. Preferably, the inlet opening has an inner diameter smaller than the outer diameter of the flange. Therefore, the damping unit is positioned at the fixing unit in a defined manner. This allows for simple mounting of the damping unit together with the fixing unit within the connector housing.

[0024] The fixing unit can be configured as an injection-molded component. The injection-molded component can have a plastic matrix. The cable sheath can be connected to the plastic matrix of the fixing unit. Alternatively or additionally, the cable sheath can be embedded in the plastic matrix. The plastic matrix can be connected in a way that mates with the cable sheath material. Alternatively or additionally, by embedding at least partially the cable sheath into the plastic matrix, a form-fitting connection can be formed between the cable sheath and the fixing unit. A form-fitting connection can be formed, for example, by arranging the plastic matrix in an undercut or recess within the cable sheath.

[0025] The cable can have reinforcing fibers. These reinforcing fibers can be embedded in the plastic matrix of the fixing unit. The reinforcing fibers can be, for example, aramid fibers or polyester fibers. The reinforcing fibers preferably extend along the cable and can surround the optical waveguide. The reinforcing fibers can be, for example, woven or knitted fabric. The reinforcing fibers are preferably surrounded by the cable sheath. However, to achieve embedding within the plastic matrix, it is preferable that the reinforcing fibers protrude at the cable ends. Attached Figure Description

[0031] Figure 1 An exploded perspective view of one embodiment of a plug connector device 1 according to the present invention is shown. The plug connector device 1 includes a plug connector housing 2, which is capable of connecting to a mating plug connector at a plugging side 3. The plug connector device 1 also includes a cable 4, a fixing unit 7, a damping unit 9, and a contact unit, which in the present embodiment is constituted by a collar housing 20 and two contact collars 21.1, 21.2. The fixing unit 7 is connected to a cable sheath 6 at the cable end 8 of the cable 4. For this purpose, the fixing unit 7 surrounds the cable sheath 6 and is connected in a material- and shape-fitting manner to the cable sheath 6. This is achieved in the present embodiment by the fixing unit 7 being configured as an injection-molded component, and the cable sheath 6 being embedded in the plastic matrix of the fixing unit 7. The cable 4 has two optical waveguides 5.1, 5.2, which extend from the fixing unit 7 at the cable end 8. The optical waveguides 5.1, 5.2 are surrounded in the region of the fixing unit 7 by a support sleeve 28 having a flange 29. Optical waveguides 5.1 and 5.2 extend to one of contact rings 21.1 and 21.2, respectively, and are segmentally surrounded by the contact ring. The two contact rings 21.1 and 21.2 respectively form contact sides 11.1 and 11.2. Optical waveguides 5.1 and 5.2 extend to contact sides 11.1 and 11.2, respectively. Optical waveguides 5.1 and 5.2 can be connected to mating connectors at contact sides 11.1 and 11.2 in a signal-conducting manner.

[0032] Furthermore, a second elastic element 22.1, 22.2 is arranged within the collar housing 20 for each contact collar 21.1, 21.2. The second elastic elements 22.1, 22.2 are held within the collar housing 20 by a stop element 24, which is also introduced into the collar housing 20. The contact unit formed by the collar housing 20 and the contact collars 21.1, 21.2 is arranged within the receiving space 12 of the damping unit 9. In the current embodiment, the damping unit 9 is formed by two half-shells that can be connected to each other. The damping unit 9 and the fixing unit 7 are arranged within the plug connector housing 2. For additional fixing, the plug connector device 1 has a secondary locking device 33.

[0033] Figure 2 A perspective view is shown of one embodiment of the damping unit 9 of the plug connector device 1 according to the present invention. A contact unit 10 is arranged within the damping unit 9. The contact unit 10 is detachably connected to the damping unit 9 via a snap-fit ​​connection. The contact unit 10 is supported within the damping unit 9 by means of a spring-elastic support element. The support element is partially constituted by a first spring tab 17, which is integrally formed with the damping unit 9. The first spring tab 17 abuts against the contact unit 10 within a receiving space and holds it in an initial position. Furthermore, the support element is constituted by a second spring tab 18, which is arranged at the contact unit 10. In the present embodiment, the second spring tab 18 is integrally formed with the collar housing 20. Additionally, the damping element has two first elastic elements 15.1 and 15.2. These two first elastic elements 15.1 and 15.2 are integrally formed with the damping unit 9.

[0034] Figure 3 A cross-sectional view of another embodiment of the plug connector device 1 according to the invention is shown. This cross-section extends parallel to the plug axis 19 and extends through the two optical waveguides 5.1, 5.2. The fixing unit 7 has first locking elements 13.1, 13.2, which are arranged in first mating locking elements 14.1, 14.2 formed by the plug connector housing 2. Therefore, the fixing unit 7 is detachably connected to the plug connector housing 2. The cable 4 also has reinforcing fibers 32, which extend from the cable sheath 6 at the cable end 8 and are embedded in the plastic matrix of the fixing element. A support sleeve 28 is pushed into the cable sheath 6 in sections, such that the support sleeve 28 is arranged in sections between the optical waveguides 5.1, 5.2. Furthermore, the support sleeve 28 is fastened to the cable end 8 by the fixing unit 7. A damping unit 9 forms an intermediate space 31 in which a flange 29 is arranged. For this purpose, the support sleeve 28 is guided into the intermediate space 31 through an access opening 30. The intermediate space 31 is separated from the receiving space 12. The optical waveguides 5.1 and 5.2 are also guided into the receiving space 12 through the entry opening 30, in which the optical waveguides 5.1 and 5.2 extend into the contact unit 10.

[0035] The damping unit 9 includes second locking elements 26.1 and 26.2, which are connected to second mating locking elements 27.1 and 27.2 of the connector housing 2. Therefore, the damping element 9 is detachably connected to the connector housing 2. A first elastic element (not shown) pre-biases the damping unit 9 against the stop surface 16 of the connector housing 2. Optical waveguides 5.1 and 5.2 extend through the stop element 24 to the corresponding contact rings 21.1 and 21.2, and are segmentally surrounded by the contact rings. The optical waveguides 5.1 and 5.2 extend to the contact sides 11.1 and 11.2. Second elastic elements 22.1 and 22.2 are respectively arranged between the contact rings 21.1 and 21.2 and the stop element 24. The second elastic elements 22.1 and 22.2 pre-biases the contact rings 21.1 and 21.2 against the ring housing wall 23. The second elastic elements 22.1 and 22.2 act parallel to the insertion axis 19.

[0036] The second spring 18, formed by the contact unit 10, abuts against the housing wall 25 of the plug connector housing 2. The first spring 17 and the second spring 18 hold the contact unit 10 in its initial position, wherein the contact unit 10 is movable radially about the plug axis. However, due to the spring support, when the contact unit 10 is moved out of its initial position, the first spring 17 and the second spring 18 return the contact unit 10 to its initial position.

[0037] Figure 4 Showing according to Figure 3 A further view of the plug connection device 1 according to the invention, wherein the plug connector housing has been removed for clarity. The first elastic elements 15.1, 15.2 abut against the fixing unit 7, thereby pre-biasing the damping unit 9 against a stop surface (not shown) of the plug connector housing.
