Description

Technical Field

[0001] This application relates to the field of automotive communication technology, specifically to a fiber optic connector, a female connector, and a connector assembly. Background Technology

[0002] Currently in China, the automotive industry is booming at an unprecedented pace, and the level of intelligence in vehicles is constantly improving. In particular, the anticipated implementation of fully autonomous driving solutions in the future presents new challenges and requirements for automotive communication in terms of latency and bandwidth.

[0003] In the field of autonomous driving, a large amount of data needs to be automatically collected and transmitted through components such as connecting cables and connectors. Due to the large number of connectors used and the complex operating environment, higher requirements are placed on the protection of connectors. Connectors in automobiles need to have good waterproof and dustproof performance to cope with harsh environments, such as heavy rain, water wading, car washing, and smog.

[0004] In related technologies, current fiber optic connectors generally have a housing, and in order to achieve a snap-fit ​​and fixation with the adapter, the housing has a hook that mates with the adapter. At the same time, in order to achieve a seal after the fiber optic connector and the adapter are plugged in and fixed, a sealing position is set on the housing of the fiber optic connector. However, the hook position needs to be exposed due to operational requirements, and the hook position is generally irregular in shape. If the sealing position is set on the side of the hook away from the adapter (that is, behind the hook), the cost of achieving a seal is very high.

[0005] Therefore, it is necessary to design a new fiber optic connector to overcome the above problems. Summary of the Invention

[0014] In conjunction with the first aspect, in one embodiment, the connector housing includes a front sleeve and a rear shell, the front sleeve and the rear shell being interlocked, and the fixing tube being clamped between the front sleeve and the rear shell; and the insert is located inside the front sleeve, the outer periphery of the insert protrudes to form a limiting boss, one side of the limiting boss abutting against the inner wall of the front sleeve, and a spring is also sleeved outside the insert, one end of the spring abutting against the fixing tube, and the other end abutting against the other side of the limiting boss.

[0042] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0043] This application provides an optical fiber connector, a female connector, and a connector assembly, which can solve the technical problem in the related art that the optical fiber connector is too large and not conducive to installation on automobiles.

[0044] See Figure 1 and Figure 2 As shown in the figure, an optical fiber connector provided in an embodiment of this application may include: a connector housing 1b, the connector housing 1b having a plug portion 15b at its front end, and a receiving cavity extending along the axial direction inside the connector housing 1b; a ferrule 2b is disposed in the receiving cavity near the plug portion 15b, and an optical cable 91b is disposed in the receiving cavity away from the plug portion 15b, the optical cable 91b having at least one optical fiber inside, the optical fiber being connected to the ferrule 2b along the receiving cavity; a locking spring arm 5b is provided on the outer side of the connector housing 1b, and a mating surface 13b is provided at the end of the plug portion 15b away from the locking spring arm 5b; the connector housing 1b also has a first sealing surface, the first sealing surface being located between the mating surface 13b and the locking spring arm 5b; the connector housing 1b also has a first anti-fooling portion 14b, the first anti-fooling portion 14b and the locking spring arm 5b at least partially overlapping along the axial direction of the connector housing 1b.

[0045] In this embodiment, the locking spring arm 5b is used to lock with the mating part (e.g., an adapter), the first sealing surface is used to contact and seal with the mating part, and the first anti-mistake part 14b is used to cooperate with the second anti-mistake part of the mating part to prevent mistakes. The rear end of the first anti-mistake part 14b is located behind the front end of the locking spring arm 5b, and the front end of the first anti-mistake part 14b is located in front of the front end of the locking spring arm 5b or flush with the front end of the locking spring arm 5b, so that the first anti-mistake part 14b and the locking spring arm 5b have a partial overlap in the axial direction, which can shorten the length of the connector housing 1b.

[0046] This embodiment, by providing a locking spring arm 5b on the connector housing 1b, can achieve locking with the mating part through the locking spring arm 5b. At the same time, the first sealing surface on the connector housing 1b is set between the mating surface 13b and the locking spring arm 5b. This not only seals and protects the core area ferrule 2b of the connector housing 1b, but also makes it easier to achieve a seal on the connector housing 1b because the first sealing surface is located in front of the locking spring arm 5b rather than behind it. This reduces the difficulty of waterproofing and solves the technical problem in related technologies where setting a sealing position on the side of the hook away from the adapter results in a very high cost for achieving a seal.

[0047] Furthermore, in one embodiment, the connector housing 1b is further provided with a first foolproof area 17b and a second foolproof area 18b, the first foolproof part 14b being disposed in the first foolproof area 17b and / or the second foolproof area 18b; the first foolproof area 17b is located between the mating surface 13b and the locking spring arm 5b, the second foolproof area 18b is located on the side of the first foolproof area 17b near the locking spring arm 5b, and at least partially overlaps with the locking spring arm 5b along the axial direction of the connector housing 1b; the first sealing surface is disposed between the first foolproof area 17b and the second foolproof area 18b.

[0048] In this embodiment, the first anti-mistake area 17b and the second anti-mistake area 18b are distributed along the axial direction of the connector housing 1b, and the first anti-mistake area 17b is located in front of the second anti-mistake area 18b. The first anti-mistake part 14b can be provided only in the first anti-mistake area 17b, only in the second anti-mistake area 18b, or in both the first and second anti-mistake areas 17b and 18b. The second anti-mistake area 18b and the locking spring arm 5b partially overlap in the axial direction, which can shorten the length of the connector housing 1b.

[0049] In one embodiment, see Figure 1 and Figure 8 As shown, the connector housing 1b also has a conductive terminal 7b inside, and at least one wire 92b is also provided in the receiving cavity of the connector housing 1b. The wire 92b is separately disposed from the optical cable 91b or is disposed integrally with the optical cable 91b. The wire 92b is connected to the conductive terminal 7b through the receiving cavity. The conductive terminal 7b is located on the outer surface of the plug portion 15b to form a contact portion 71b. The contact portion 71b is located between the mating surface 13b and the first sealing surface.

[0050] In this embodiment, a conductive terminal 7b is provided inside the connector housing 1b, enabling the fiber optic connector to transmit not only optical signals but also electrical signals. At the same time, the contact portion 71b of the conductive terminal 7b is disposed between the mating surface 13b and the first sealing surface, so that the first sealing surface can seal and protect the contact portion 71b in the core area.

[0051] Furthermore, in one embodiment, see... Figure 2 and Figure 6 As shown, the contact portion 71b and the first foolproof area 17b at least partially overlap along the axial direction of the connector housing 1b. In this embodiment, the front end of the contact portion 71b can be located after the front end of the first foolproof area 17b, while the rear end of the contact portion 71b can be located before the rear end of the first foolproof area 17b, so that the contact portion 71b completely overlaps with the first foolproof area 17b in the axial direction, which can shorten the length of the connector housing 1b; or the contact portion 71b and the first foolproof area 17b can also partially overlap along the axial direction.

[0052] In one embodiment, see Figure 2 and Figure 3 As shown, the connector housing 1b is provided with an outer sealing ring 6b, which is located between the mating surface 13b and the locking spring arm 5b. The outer sealing ring 6b has the first sealing surface. In this embodiment, it is preferable to provide the outer sealing ring 6b on the outside of the connector housing 1b, and the outer surface of the outer sealing ring 6b forms the first sealing surface. In other embodiments, the outer sealing ring 6b may not be provided, and the first sealing surface may be formed directly by the outer surface of the connector housing 1b.

[0053] Furthermore, in some embodiments, the optical cable 91b forms an adhesive injection channel 19b with the inner wall of the receiving cavity, and the adhesive injection channel 19b contains adhesive. In this embodiment, the optical cable 91b can be directly fixed to the receiving cavity with adhesive. In other embodiments, the optical cable 91b can also adopt other fixing methods, which are not limited here.

[0054] In some alternative embodiments, see Figure 1 and Figure 4 As shown, the ferrule 2b is confined within the receiving cavity by a fixing tube 10b located within the receiving cavity. The fixing tube 10b includes: a fixing sleeve 101b, which engages with the connector housing 1b and, in conjunction with the connector housing 1b, confines the ferrule 2b within the receiving cavity; and an empty tube 102b, which is inserted into the fixing sleeve 101b, and the optical cable 91b passes through the empty tube 102b and the fixing sleeve 101b.

[0055] In this embodiment, the fixing sleeve 101b can be provided with a snap-fit ​​position for snapping with the connector housing 1b. After the fixing sleeve 101b snaps with the connector housing 1b, the fixing sleeve 101b and the connector housing 1b are relatively fixed. At the same time, the connector housing 1b and the fixing sleeve 101b can be provided with corresponding limiting structures, so that after the fixing sleeve 101b and the connector housing 1b are fixed, the ferrule 2b can be limited within the receiving cavity by the connector housing 1b and the fixing sleeve 101b. One end of the empty tube 102b can be inserted into the fixing sleeve 101b, and the other end can extend out of the fixing sleeve 101b. When the optical cable 91b is inserted into the fixing tube 10b, it first goes into the empty tube 102b, and then into the fixing sleeve 101b. The optical fiber is inserted into the ferrule 2b. In this embodiment, the fixing tube 10b is divided into two parts: the fixing sleeve 101b and the empty tube 102b. This not only facilitates the processing and manufacturing of the fixing tube 10b, but also allows one end of the empty tube 102b to be inserted into the fixing sleeve 101b. After the glue is injected between the inner wall of the receiving cavity and the empty tube 102b, the glue is not easy to enter the empty tube 102b from that end, and thus it is not easy to fix the optical cable 91b in the empty tube 102b. The optical cable 91b can move inside the empty tube 102b.

[0056] In one embodiment, see Figure 7 As shown, the ferrule 2b is fitted with a ferrule sealing ring 3b, and the ferrule sealing ring 3b is sandwiched between the ferrule 2b and the connector housing 1b.

[0057] In this embodiment, the connector housing 1b can be either integral or separate. To facilitate the assembly of the ferrule 2b, this embodiment preferably uses a separate connector housing 1b. Furthermore, the ferrule sealing ring 3b is directly installed outside the ferrule 2b. After the ferrule 2b is assembled into the connector housing 1b, the ferrule sealing ring 3b is sandwiched between the outer wall of the ferrule 2b and the inner wall of the connector housing 1b. This prevents dust and water from entering the ferrule 2b from the inner wall of the connector housing 1b. This not only seals and waterproofs the core area of ​​the fiber optic connector, the ferrule 2b, but also eliminates the need for a sealing structure on the connector housing 1b to seal the inside of the ferrule 2b. The ferrule sealing ring 3b being located inside the connector housing 1b effectively reduces the size of the fiber optic connector.

[0058] Based on the above technical solution, in one embodiment, a sealing groove 21b is provided on the outside of the ferrule 2b, and the ferrule sealing ring 3b is received in the sealing groove 21b. In this embodiment, a sealing groove 21b is provided on the outside of the ferrule 2b, and the ferrule sealing ring 3b is received in the sealing groove 21b, and the ferrule sealing ring 3b at least partially protrudes from the sealing groove 21b, ensuring tight contact between the ferrule sealing ring 3b and the inner wall of the connector housing 1b; at the same time, by providing a sealing groove 21b on the ferrule 2b, this embodiment eliminates the need for a large gap between the ferrule 2b and the connector housing 1b to accommodate the ferrule sealing ring 3b, which can further reduce the overall volume of the fiber optic connector, and the ferrule sealing ring 3b, being received in the sealing groove 21b, is less likely to move axially outside the ferrule 2b.

[0059] Furthermore, in one embodiment, see... Figure 1 and Figure 5 As shown, the connector housing 1b includes a front sleeve 11b and a rear shell 12b, which are interlocked. The fixing tube 10b is clamped between the front sleeve 11b and the rear shell 12b. The insert 2b is located inside the front sleeve 11b, and a limiting boss 22b protrudes from the outer periphery of the insert 2b. One side of the limiting boss 22b abuts against the inner wall of the front sleeve 11b. A spring 4b is also sleeved on the outside of the insert 2b. One end of the spring 4b abuts against the fixing tube 10b, and the other end abuts against the other side of the limiting boss 22b.

[0060] In this embodiment, the connector housing 1b adopts a split structure, namely a front sleeve 11b and a rear housing 12b. A spring 4b is also sleeved on the outside of the ferrule 2b. After the front sleeve 11b and the rear housing 12b are engaged with each other, one side of the limiting boss 22b abuts against the inner wall of the front sleeve 11b, and one end of the spring 4b away from the limiting boss 22b abuts against the rear housing 12b. The other end of the spring 4b abuts against the other side of the limiting boss 22b, thereby fixing the ferrule 2b inside the front sleeve 11b and the rear housing 12b. At the same time, since the ferrule sealing ring 3b is set on the ferrule 2b, it will affect the movement of the ferrule 2b. The influence of the ferrule sealing ring 3b on the ferrule 2b can be offset by adjusting the force of the spring 4b.

[0061] See Figure 9 and Figure 10 As shown, this application embodiment also provides a female connector for mating with the fiber optic connector in any of the above embodiments. The female connector may include: a connector body 200b, the connector body 200b having a second sealing surface 201b for sealing with the first sealing surface of the fiber optic connector, and the connector body 200b having a second anti-fooling part that cooperates with the first anti-fooling part 14b. The connector body 200b also has a locking groove that cooperates with the locking spring arm 5b for locking.

[0062] In this embodiment, a ceramic sleeve 8b is provided inside the connector body 200b, and one end of the ceramic sleeve 8b is used to be inserted into the ferrule 2b inside the male connector (i.e., the fiber optic connector mentioned above).

[0063] See Figure 10 and Figure 11 As shown, this application embodiment also provides a connector assembly, which includes an optical cable 91b; and also includes the above-mentioned optical fiber connector and / or the above-mentioned female connector. Figure 11 The diagram shows one end of the optical cable 91b connected to an optical fiber connector and the other end connected to a female connector. The optical fiber connector in this embodiment can be any of the optical fiber connectors described in the above embodiments and achieve the corresponding functions, which will not be elaborated further here; similarly, the female connector can be any of the female connectors described in the above embodiments and achieve the corresponding functions, which will not be elaborated further here.
