Description

Technical Field

[0001] This utility model belongs to the field of connector technology, specifically relating to an automotive optoelectronic connector and a prefabricated cable structure. Background Technology

[0002] With the automotive industry accelerating its move towards intelligent and connected development, intelligent connected vehicles have become a commanding height in global technological and industrial competition. As perception systems, decision-making and control, and interactive experiences continue to improve, future intelligent vehicles will require an increasing number of high-precision sensing devices, such as 4K high-definition cameras, high-line-count LiDAR, and millimeter-wave radar. This leads to enormous data transmission demands on automotive systems. For example, a single 4K camera can achieve a data transmission rate exceeding 10Gbps at 60FPS, while LiDAR can reach 1Gbps. The total bandwidth requirement for the vehicle's backbone network is expected to reach 25-50Gbps.

[0003] Faced with such massive data transmission demands, traditional copper cable communication methods are proving unsustainable, suffering from bandwidth bottlenecks, complex cabling, excessive weight, and insufficient anti-interference capabilities, making them inadequate for the data transmission needs of intelligent connected vehicles. In contrast, fiber optic communication technology possesses inherent advantages such as high bandwidth, low loss, resistance to electromagnetic interference, light weight, and small size, making it the preferred solution for large data transmissions and an ideal choice for upgrading intelligent connected vehicle communication systems. However, while fiber optic communication technology has mature applications in other communication fields, its application scenarios and data transmission characteristics in the intelligent vehicle field mean that mature technologies from other fields often cannot be directly transferred to automobiles, requiring targeted design and improvements.

[0026] Below, for reference Figures 1-15 The present invention describes a vehicle-mounted optoelectronic connector and a prefabricated cable structure according to a preferred embodiment.

[0027] The vehicle-mounted optoelectronic connector in the preferred embodiment is designed to enable simultaneous conduction of optical communication and electrical transmission, and is particularly suitable for the simultaneous transmission of optical signals and power in the field of intelligent vehicles.

[0028] One aspect of this utility model is to provide an in-vehicle optoelectronic connector, which includes a housing 1, an inner core assembly 2, and a power connection assembly 3.

[0029] Specifically, the outer casing 1 is provided with an independent inner core cavity 103 and a power connection cavity 104, which are used for embedding the inner core assembly 2 and the power connection assembly 3, respectively. Moreover, one end of the outer casing 1 is a plug-in terminal 101, which is used to plug into the female connector to complete electrical conduction and optical transmission; the other end of the outer casing 1 is a wiring terminal 102, which is used to connect the cable section 6 and the optical cable section 5. Meanwhile, the inner core assembly 2 includes an inner core 203 with a central hole 2031; one end of the inner core 203 is used to connect the optical cable section 5 and connect to the optical fiber unit, and the other end is used to assemble the spring 202 and the ferrule 201, so that the optical fiber unit can extend along the central hole 2031 and connect with the ferrule 201; and the assembled inner core assembly 2 can be fixed after being embedded in the inner core cavity 103, thereby realizing the assembly setting of the inner core assembly 2 in the outer shell 1.

[0030] In addition, the power connection assembly 3 includes a power connection terminal 301, which can be embedded and fixed in the power connection cavity 104 after being connected to the wire unit in the cable section 6, thereby realizing the assembly and installation of the power connection assembly 3 in the housing 1.

[0031] In the preferred embodiment of the vehicle-mounted optoelectronic connector, the independent arrangement of the inner core cavity 103 and the power connection cavity 104 in the outer shell 1 provides conditions for the separate embedding of the inner core component 2 and the power connection component 3, thereby reliably realizing optical communication and electrical transmission and meeting the application requirements of vehicle-mounted optoelectronic connectors.

[0032] Furthermore, in the preferred embodiment, the inner core assembly 2 also includes an inner core end cap 204 detachably connected to one end of the inner core 203. Meanwhile, one end of the spring 202 is limited and embedded in the central hole 2031, and the other end is sleeved and abuts against the middle of the insert 201; correspondingly, the end of the insert 201 facing away from the spring 202 passes through the inner core end cap 204, and the inner core end cap 204 axially limits and assembles the insert 201 to one end of the inner core 203.

[0033] By using the inner core end cap 204, after the ferrule 201 is connected to the optical fiber unit, it can be reliably limited by the inner core end cap 204 to one end of the inner core 203. This allows the inner core assembly 2 to be pre-assembled with the optical cable section 5 as a semi-finished structure, ensuring the integrity of the inner core assembly 2 and the optical cable section 5 after assembly. This facilitates the transfer of the semi-finished product after assembly and ensures the reliability of the ferrule 201 in the transfer process.

[0034] More specifically, in relation to the fixing of the inner core assembly 2 in the inner core cavity 103 of the outer shell 1, an inner core fixing assembly 4 is preferably provided to achieve reliable fixing of the inner core assembly 2 in the outer shell 1.

[0035] In actual installation, the inner core fixing component 4 can be set in the middle of the outer shell 1 or at the end of the terminal 102, as long as the inner core component 2 can be fixed in the outer shell 1.

[0036] As a feasible example, in the preferred embodiment, the inner core fixing assembly 4 includes a limiting card 401, and an embedding slot 402 communicating with the inner core cavity 103 is formed on the outer periphery of the outer shell 1, such as... Figure 11 As shown in the diagram. Simultaneously, a limiting slot 403 is formed on the outer periphery of the inner core, as... Figure 7 , Figure 9 As shown in the diagram. More specifically, the limiting slot 403 can be aligned with the embedding slot 402 after the inner core assembly 2 is embedded in the inner core cavity 103; at this time, one end of the limiting card 401 can be connected to the limiting slot 403 after passing through the embedding slot 402, and the other end of the limiting card 401 is located in the embedding slot 402, thereby realizing the axial fixation of the inner core assembly 2 in the outer shell 1.

[0037] By utilizing the aforementioned inner core fixing component 4, reliable fixation between the inner core component 2 and the outer shell 1 can be achieved. Furthermore, since no additional connecting mechanism, such as an end connecting sleeve, is required for the inner core component 2 on the terminal 102 side, to ensure the reliability of the assembly between the inner core component 2 and the inner core cavity 103, the outer diameter of the tail end of the inner core 203 (the end connecting the optical cable portion 5) is preferably the same as (or slightly smaller than) the inner diameter of the inner core cavity 103 on the terminal 102 side. This ensures that after the inner core 203 is embedded in the inner core cavity 103, the gap between them is as small as possible, thereby preventing water and impurities from seeping into the inner core cavity 103.

[0038] More specifically, regarding the aforementioned inner core fixing component 4, the limiting slot 403 and the embedding slot 402 are respectively arc-shaped slots opened along the circumferential direction, and the limiting clip 401 is a U-shaped buckle, such as... Figure 1 As shown in the diagram. At this time, the open side of the U-shaped buckle is embedded in the mounting groove 402 and connected to the limiting groove 403, and the closed side of the U-shaped buckle does not protrude from the surface of the outer casing 1. In actual installation, to facilitate the removal of the limiting card 401, it is preferable to provide a removal groove or removal hole on its closed side, and to provide a clearance notch on one side of the mounting groove 402 corresponding to the removal groove or removal hole, as shown in the reference diagram. Figure 11 As shown, a pin-type device can then be used to match the extraction slot or extraction hole, and the locking card 401 in the locked state can be removed.

[0039] Furthermore, a stepped surface 302 is formed in the middle of the electrical terminal 301, such as... Figure 2 As shown in the figure. Accordingly, a locking hole 105 communicating with the power-connecting cavity 104 is provided on the outer shell 1, and a locking component 7 is provided in the locking hole 105 corresponding to the stepped surface 302, so that the locking component 7 can achieve axial locking of the power-connecting terminal 301 by abutting and matching with the stepped surface 302 after the power-connecting terminal 301 is embedded in the position.

[0040] As a viable example, locking component 7, such as Figure 1 , Figure 2 As shown in the diagram. At this time, the locking assembly 7 has a locking cover 701 with a limiting portion 702 on its inner surface. The locking cover 701 can be installed in the locking hole 105 after the power terminal 301 is inserted into the power connection cavity 104, causing the limiting portion 702 to abut against the stepped surface 302. By utilizing the detachable connection of the locking cover 701 in the locking hole 105, the limiting portion 702 and the stepped surface 302 can be aligned and abutted, thereby achieving axial limiting of the power terminal 301 and preventing the power terminal 301 from retracting during subsequent insertion.

[0041] As another feasible example, the locking component 7 is a resilient arm 703 disposed on the inner wall surface of the locking hole 105 (the side wall surface near the terminal 102), such as... Figures 12-15 As shown in the diagram. At this time, one end of the elastic arm 703 is the connecting end connected to the outer shell 1, and the other end is the cantilever end 7031. A limiting protrusion 7032 is provided on the side of the cantilever end 7031 facing the power-connecting cavity 104. The elastic arm 703 has a certain elasticity, and its cantilever end 7031 can be elastically deflected up and down relative to the connecting end. When the power-connecting terminal 301 is embedded in the power-connecting cavity 104, the front end of the power-connecting terminal 301 first lifts the cantilever end 7031. After it is embedded in place, the stepped surface 302 of the power-connecting terminal 301 passes over the cantilever end 7031. Then, the limiting protrusion 7032 can abut against the stepped surface 302 after the power-connecting terminal 301 is embedded in the power-connecting cavity 104, thereby completing the reliable embedding of the power-connecting terminal 301 in the power-connecting cavity 104.

[0042] In actual installation, the power terminals 301 in the preferred embodiment are preferably arranged in pairs. In this case, the power connection cavity 104 includes two parallel embedded cavities, so that the two power terminals 301 can be respectively embedded in the two embedded cavities and fixed.

[0043] For the paired electrical terminals 301, the aforementioned locking assembly 7 can provide a locking element for each electrical terminal 301, or it can provide a single locking element to simultaneously lock both electrical terminals 301 axially. For example, in Figure 12 In the middle, flexible arms 703 are respectively provided for the two electrical terminals 301; while Figure 14 In this configuration, a resilient arm 703 is provided for each of the two electrical terminals 301, and this resilient arm 703 is used to axially lock the two electrical terminals 301. Similarly, for Figure 1 Regarding the locking cover 701 shown, when there are multiple electrical terminals 301, the multiple electrical terminals 301 can be locked by the corresponding locking covers 701 respectively, or they can be locked by the same locking cover 701 at the same time. This can be preferred as needed, and will not be elaborated here.

[0044] Furthermore, in the preferred embodiment, the inner core 203 includes an integrally formed inner core body 2032 and an inner core metal insert 2033, which are integrally formed or detachably connected. Meanwhile, the insert 201 is disposed at the end of the inner core body 2032 opposite to the inner core metal insert 2033, and the inner core metal insert 2033 is used to attach to the end of the optical cable portion 5.

[0045] The connection between the inner core metal insert 2033 and the end of the optical cable section 5 can be fixed by crimping, glue, or both, to ensure the reliability of the connection at the end of the optical cable section 5.

[0046] More specifically, in order to achieve pre-fixation of the inner core component 2 when it is embedded in the inner core cavity 103, in a preferred embodiment, a locking hook 2034 is provided protruding from the outer periphery of the inner core 203, and a locking groove 106 is provided on the inner wall surface of the inner core cavity 103. The locking hook 2034 can be engaged in the locking groove 106 after the inner core component 2 is embedded in place, thereby achieving pre-fixation of the inner core component 2 before axial locking by the inner core fixing component 4, which facilitates the installation of the limit card 401 and ensures the convenience and reliability of the inner core component 2.

[0047] Meanwhile, in order to achieve circumferential locking during the installation of the inner core component 2, it is preferable to provide a limiting groove 107 along the axial direction in the inner core cavity 103 on one side of the terminal 102, and to provide a limiting rib 2035 along the axial direction on the outer periphery of the inner core component 2. The limiting groove 107 extends inward from the end of the terminal 102 (inner side of the inner core cavity 103), and the limiting rib 2035 can be embedded in the limiting groove 107 when the inner core component 2 extends inward into the inner core cavity 103, thereby achieving guidance and circumferential limiting during the installation of the inner core component 2.

[0048] As a special type of setup, in cases such as Figure 7 In the preferred embodiment shown, the aforementioned locking hook 2034 and limiting rib 2035 are preferably integrated. In this case, a limiting rib 2035 extending axially protrudes from the outer periphery of the inner core 203, and a locking hook 2034 protrudes from the side of the limiting rib 2035 opposite to the inner core 203. Correspondingly, a limiting groove 107 is formed axially on the inner wall surface of the inner core cavity 103 on the side of the terminal 102, and a locking groove 106 is formed at the bottom of the limiting groove 107, such as... Figure 6 As shown in the figure. Thus, the limiting rib 2035 can be embedded in the limiting groove 107 when the inner core assembly 2 extends inward into the inner core cavity 103, and the locking hook 2034 can be embedded in the locking groove 106 after the inner core assembly 2 is in place.

[0049] More preferably, for the vehicle-mounted optoelectronic connector in the preferred embodiment, a ferrule protective sleeve 108 is provided axially at the insertion end 101 of the housing 1, so that after the inner core assembly 2 is assembled in the inner core cavity 103, the ferrule end face of its ferrule 201 does not protrude from the end face of the ferrule protective sleeve 108, thereby providing protection for the ferrule 201 of the vehicle-mounted optoelectronic connector.

[0050] More preferably, in actual installation, the ferrule protective sleeve 108 is integrally formed with or detachably connected to the end of the insertion end 101.

[0051] Furthermore, to ensure proper alignment when the vehicle-mounted optoelectronic connector is inserted into the female connector, a foolproof mechanism 109 is preferably provided on the end face and / or outer periphery of the insertion end 101. Correspondingly, a matching structure, such as a foolproof groove or a foolproof inner contour, is provided in the female connector to match the foolproof mechanism 109, to ensure that the assembly state of the insertion end 101 and the female connector is unique when they are inserted.

[0052] In actual installation, the aforementioned anti-mistake mechanism 109 may preferably include an anti-mistake unit disposed on the outer periphery or end face (e.g., the outer periphery of the ferrule protective sleeve 108) of the end of the plug-in end 101. Alternatively, the end of the plug-in end 101 may preferably be provided with an irregular structure, such as a D-shaped structure, in order to complete the anti-mistake design.

[0053] By using the foolproof mechanism 109, not only can the accuracy of the mating assembly of the plug end 101 and the female head be guaranteed, but different plugging objects can also be distinguished according to the different foolproof mechanisms 109, so as to prevent the mis-plugging of vehicle optoelectronic connectors.

[0054] More specifically, in order to ensure the reliability of the connection between the vehicle-mounted optoelectronic connector and the female head, it is also preferable to provide a plug-in locking mechanism 110 on one side of the housing 1 for locking the plug end 101 after it is plugged into the female head; correspondingly, on one side of the inner cavity of the female head, a locking member (e.g., a locking slot) is provided for the plug-in locking mechanism 110, so that the plug-in locking mechanism 110 can interlock and match with the locking member after the plug end 101 is plugged into place.

[0055] In addition, the inner core assembly 2 in the preferred embodiment preferably also includes a dust cap 205, which can be sleeved on the end of the insert 201 after the inner core assembly 2 is in place, to provide protection for the end face of the ground insert.

[0056] Meanwhile, the vehicle-mounted optoelectronic connector in the preferred embodiment also includes a tail sleeve 8, which is detachably connected to the tail end of the inner core 203 (e.g., the tail end of the inner core metal insert 2033, such as...). Figure 2 , Figure 3 (as shown in the diagram) or can be detachably connected to terminal 102.

[0057] Furthermore, another aspect of this utility model provides a prefabricated cable structure based on the aforementioned vehicle-mounted optoelectronic connector, such as... Figure 10 , Figure 11 As shown in the image.

[0058] Specifically, the prefabricated cable structure includes the aforementioned vehicle-mounted optoelectronic connector and the cable connected to the vehicle-mounted optoelectronic connector. The cable includes independently configured optical cable section 5 and electrical cable section 6, or the cable is an integrated optoelectronic composite cable comprising optical cable section 5 and electrical cable section 6.

[0059] In detail, one end of the optical cable section 5 is connected to one end of the inner core 203, and the optical fiber unit in the optical cable section 5 extends along the central hole 2031 and is connected to the ferrule 201 assembled at the other end of the inner core 203; the wire unit of the cable section 6 is connected to the power terminal 301, and the power terminal 301 is embedded and fixed in the power cavity 104. At the same time, the inner core assembly 2 connected to the optical cable section 5 is embedded in the inner core cavity 103 axially and fixed, for example, by using the aforementioned limiting card 401 for axial fixation.

[0060] The vehicle-mounted optoelectronic connector of this invention has a compact structure and is easy to assemble. It can simultaneously connect the optical fiber unit and the wire unit in the vehicle-mounted optoelectronic connector, meeting the optical communication and electrical transmission requirements of the vehicle-mounted optoelectronic connector. This enables the vehicle-mounted optoelectronic connector to meet the application requirements in special application scenarios, especially the application requirements in the field of intelligent vehicles, and has excellent practical value.

[0061] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
