Description

Technical Field

[0001] This utility model belongs to the field of connector technology, specifically relating to an automotive optoelectronic connector and an automotive optoelectronic 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.

[0025] Below, for reference Figures 1-12 This invention describes a vehicle-mounted optoelectronic connector according to a preferred embodiment of the present invention, and a vehicle-mounted optoelectronic connector assembled based on the optoelectronic connector.

[0026] As one aspect of this utility model, an in-vehicle optoelectronic connector is provided. In a preferred embodiment, the in-vehicle optoelectronic connector includes a housing 1 with an inner cavity and an inner core assembly 2 that can be assembled and embedded in the inner cavity.

[0027] The outer shell 1 has a cylindrical structure, with one end being a plug-in end 101 for plugging into the corresponding connector female head, and the other end being a wiring end 102 for connecting the optical fiber composite cable 6. The outer shell 1 also has an inner cavity for accommodating the inner core assembly 2.

[0028] Meanwhile, in the preferred embodiment, the inner core component 2, as... Figure 1 , Figure 2As shown, it includes an inner core 203 and a ferrule 201 and a spring 202 that can be assembled with the inner core 203, as well as a separately provided power terminal 205.

[0029] Furthermore, the inner cavity of the plug-in terminal 101 is formed with layered inner core through grooves and terminal through grooves, wherein the inner core through grooves are used for assembling the inner core 203 to embed one end of the plug core 201, and the terminal through grooves are used for embedding the electrical terminal 205.

[0030] Furthermore, the inner core 203 has an inner hole extending through both ends, and an opening 2034 communicating with the inner hole is formed on the outer periphery of the middle part of the inner core 203. Meanwhile, one end of the spring 202 can be sleeved onto the tail end of the insert 201 and abut against it for positioning, while the other end can be inserted into one end of the inner hole for positioning. The other end of the inner hole is used to introduce the optical fiber unit 601 and the wire unit 602 of the optoelectronic composite cable 6.

[0031] In detail, the ferrule 201 is used to connect to the optical fiber unit 601 introduced into the inner hole; the electrical terminal 205 is used to connect to the wire unit 602 extending from the opening 2034 and can be embedded and fixed in the terminal through slot 2062. Subsequently, one end of the inner core 203 can be embedded and fixed in the inner core through slot 2061 after assembling the ferrule 201 and the spring 202, and the other end of the inner core 203 is assembled and fixed to the wiring terminal 102.

[0032] Furthermore, in actual installation, the inner core through groove and terminal through groove formed in the inner cavity of the plug-in end 101 can be formed directly inside the outer shell 1, or they can be formed in the corresponding components that can be embedded inside the plug-in end 101.

[0033] For example, in such Figure 2 , Figure 9 In the preferred embodiment shown, the insertion end 101 is provided with two chambers, one of which is an inner core through groove. Figure 2 , Figure 9 The lower chamber is used for assembling one end of the insert 201 with the inner core 203. Accordingly, in the preferred embodiment, the end of the inner core 203 integrates both an inner core body 2031 for assembling the tail end of the insert 201 and a terminal body 2037 for assembling the electrical terminal 205. The inner core body 2031 and the terminal body 2037 are arranged in layers, and the terminal body 2037 preferably protrudes beyond the end of the inner core body 2031, such as... Figure 1 As shown in the figure. At the same time, another chamber in the plug end 101, other than the inner core through groove 2061, is used for the embedding of the terminal body 2037, and the terminal through groove is provided in the terminal body 2037.

[0034] In the aforementioned embodiments, the inner core through slot and the terminal through slot are formed inside the outer casing 1 and at the end of the inner core 203, respectively.

[0035] In another embodiment, such as Figures 3-6 , Figure 10 , Figure 11 As shown, the inner core through groove and the terminal through groove are respectively formed in the inner shell 206, which is detachably disposed in the inner cavity of the plug-in end 101. At this time, an inner cavity for accommodating the inner shell 206 is formed in the plug-in end 101, and the inner core through groove 2061 and the terminal through groove 2062 are layered on the inner shell 206, so that after the inner core 203 and the electrical terminal 205 are respectively assembled on the inner shell 206, the inner shell 206 is then embedded into the outer shell 1, thereby completing the setting of the inner core assembly 2 in the outer shell 1.

[0036] In the aforementioned embodiment, the inner shell 206 allows the inner core 203 and the power terminal 205 to be pre-assembled outside the outer shell 1, enabling the pre-assembly of the ferrule 201 and spring 202 before assembly with the outer shell 1, thus facilitating the assembly process of the optoelectronic connector.

[0037] More specifically, in the preferred embodiment of the aforementioned inner shell 206, the end of the inner core 203 used for assembling the inner core through slot 2061 is the inner core body 2031, which has an inner core hole 2033 formed therein. The tail end of the insert 201 for assembling the spring 202 can be coaxially embedded in the inner core hole 2033. Thereafter, the inner core body 2031 can be coaxially embedded in the inner core through slot 2061 and fixed in place, as shown below. Figure 4 , Figure 6 As shown in the image.

[0038] Of course, the connection between the inner core body 2031 and the inner core through slot 2061 can be... Figure 6 In the snap-fit ​​connection, it is preferable to set a limiting protrusion on the outer periphery of the end of the inner core body 2031 and set a corresponding limiting slot in the inner core through groove 2061, and complete the snap-fit ​​connection by using the embedding of the limiting protrusion in the limiting slot.

[0039] It is understandable that, in addition to the aforementioned snap-fit ​​connection, the connection between the inner core body 2031 and the inner core through groove 2061 can also take other forms, such as threaded connection or limit member connection, which will not be elaborated here.

[0040] In addition, regarding the actual arrangement of the inner core through slot and the terminal through slot, besides the aforementioned "both are set on the corresponding parts that can be embedded in the housing 1" or "partially formed in the housing 1 and partially formed on the corresponding parts that can be embedded in the housing 1", they can also be set in the inner cavity of the plug-in end 101 of the housing 1 at the same time, as long as the power terminal 205 and the inner core 203 can be assembled with the two through slots, which will not be elaborated here.

[0041] Furthermore, in the inner core assembly 2 embedded in the outer shell 1, the insert end face of the insert 201 extends out of the insertion end 101, one side of the limiting protrusion in the middle of the insert 201 abuts against the inner wall surface of the inner core through groove 2061, and the other side abuts against and matches one end of the spring 202. The spring 202 is in a compressed state, and its other end is limited to abutting against or connected to the inner hole of the inner core 203.

[0042] More specifically, in the preferred embodiment, a connecting part 5 is provided on the outer periphery of the inner core 203 for introducing the optoelectronic composite cable 6. The inner core 203 is fixed in the outer shell 1 by connecting the connecting part 5 to the terminal 102.

[0043] In actual installation, the connection between the connecting part 5 and the housing 1 can be a connection to the outer periphery of the terminal 102, for example... Figure 2 , Figure 3 As shown, it can also be connected to the inner cavity of terminal 102, for example. Figure 5 , Figure 9 , Figure 10 As shown in the image.

[0044] As an example, with Figure 2 Taking the structure shown as an example, the connecting part 5 is preferably a sleeve fitted on the outer periphery of the end of the inner core 203. The inner diameter of the sleeve matches the outer diameter of the terminal 102, and can be connected to the outer periphery of the terminal 102 after the inner core assembly 2 is embedded in the outer shell 1.

[0045] As another example, Figure 5 Taking the structure shown as an example, the connecting part 5 is a plug located on the outer periphery of the end of the inner core 203. The outer diameter of the plug matches the inner diameter of the terminal 102, so that the plug can be aligned and embedded in the inner cavity of the terminal 102 after the inner core assembly 2 is embedded in the outer shell 1.

[0046] Furthermore, the connection method between the connecting part 5 and the terminal 102 can be selected as needed, such as using a snap-fit ​​connection, a threaded connection, or a limiting member connection. Figure 2 , Figure 3 , Figure 5 , Figure 9 , Figure 10 In the preferred embodiment shown, the aforementioned connection methods are all snap-fit ​​connections.

[0047] Furthermore, to ensure the alignment accuracy of the inner core component 2 during assembly with the outer shell 1 and the anti-torsion performance after assembly, in a preferred embodiment, a rib plate 2035 is provided on the outer periphery of the inner core 203, which is further preferably located on the side of the inner core 203 facing away from the opening 2034. At the same time, a positioning groove 107 is provided in the inner cavity of the outer shell 1 from the wiring terminal 102 inward, so that the rib plate 2035 can be aligned and embedded in the positioning groove 107 when the inner core component 2 is embedded in the outer shell 1, ensuring the alignment and embedding of the inner core component 2 while also realizing the anti-torsion design after the inner core component 2 is installed.

[0048] Meanwhile, in order to achieve axial positioning of the inner core component 2 after assembly, it is preferable to provide an annular baffle 2036 around the outer periphery of the tail end of the inner core 203, so that after the connecting part 5 is connected in place on the terminal 102, the end of the connecting part 5 is limited and abuts against the annular baffle 2036, thereby achieving axial positioning and fixing of the inner core 203 and ensuring the reliability of the inner core component 2 in the outer shell 1.

[0049] Furthermore, a tail sleeve 3 is provided at the tail end of the connector, and a tail sleeve connecting part 502 is provided at one end of the connecting part 5 corresponding to the connection of the tail sleeve 3; at this time, a housing connecting part 501 (such as a plug or socket) for connecting the terminal 102 is formed at the other end of the connecting part 5.

[0050] More specifically, when the connecting part 5 is provided, it preferably includes a housing connecting part 501 and a tail sleeve connecting part 502 coaxially arranged, the former for connecting to the wiring terminal 102 of the housing 1, and the latter for connecting to the tail sleeve 3, such as Figure 1 As shown in the image.

[0051] More preferably, to correspond to the live wire and neutral wire in the power supply line, the power connection terminals 205 are preferably arranged in pairs, and the two power connection terminals 205 are independently arranged in the terminal through slot. In this case, the terminal through slot preferably includes two independently arranged embedded cavities.

[0052] It is understood that the aforementioned arrangement of the two electrical terminals 205 within two embedded cavities can be implemented in all the aforementioned embodiments. For example, two embedded cavities can be arranged side-by-side in the terminal body 2037, such as... Figure 1 As shown in the diagram; or, two embedded cavities are arranged side by side in the inner shell 206, and the terminal through groove 2062 formed by the two embedded cavities is arranged in layers with the inner core through groove 2061 in the inner shell 206, as shown in the diagram. Figure 6 As shown in the image.

[0053] More preferably, in actual installation, the terminal through groove and the inner core through groove formed in the plug end 101 are directly opposite each other in the layering direction (not misaligned). In this case, for the terminal through groove containing two embedded cavities, the axis of the inner core through groove 2061 is equidistant from the axis of the two embedded cavities. Figure 6 , Figure 7 As shown in the image.

[0054] Furthermore, in the foregoing embodiments, the inner core through-slot is preferably coaxially arranged with the outer shell 1, and one end of the inner core 203 used to connect to the optoelectronic composite cable 6 is coaxially arranged with the terminal 102, such as... Figure 2 , Figure 3 , Figure 5 As shown in the figure. This configuration ensures that after the optoelectronic composite cable 6 is connected to the optoelectronic connector, the axis of the optoelectronic composite cable 6 is coaxially set with the outer shell 1. At this time, the tail end of the inner core 203 is coaxially assembled with the terminal 102. The connecting part 5 used to connect the terminal 102 can be coaxially connected with the terminal 102. There are more options for the connection method between the two (in addition to snap connection, limit member connection, threaded connection, etc.), which provides convenience for the design of optoelectronic connectors.

[0055] Of course, in addition to the aforementioned method, the end of the inner core 203 used for connecting the optoelectronic composite cable 6 can also be eccentrically connected to the terminal 102, such as... Figure 9 , Figure 10 As shown in the diagram. This eccentric design allows for a reduction in the outer diameter of the housing 1, enabling miniaturization of the optoelectronic connector.

[0056] from Figure 9 , Figure 10 It is not difficult to see that the connecting part 5 is an eccentric structure. After it is set on the outer periphery of the end of the inner core 203, it cannot rotate coaxially with the outer shell 1 when it is assembled with the terminal 102. The preferred connection method is a snap-fit ​​connection or a limit member connection after being embedded / sleeved.

[0057] Furthermore, in the preferred embodiment, after the inner core assembly 2 is installed, its insert 201 extends out of the end face of the insertion end 101. In order to protect the end face of the insert 201, in the preferred embodiment, the end of the insertion end 101 is provided with an insert protective sleeve 103 that is coaxial with the inner core through groove 2061.

[0058] More specifically, in the preferred embodiment, the ferrule protective sleeve 103 is integrally formed with the outer casing 1 or is detachably connected, for example, in Figure 1 In the preferred embodiment shown, the ferrule protective sleeve 103 is integrally formed with the outer shell 1. At the same time, the ferrule end face of the ferrule 201 can extend into the ferrule protective sleeve 103 after the inner core assembly 2 is inserted into place, so that the ferrule end face does not protrude from the end of the ferrule protective sleeve 103.

[0059] In practical use, the assembled ferrule 201 often requires end-face inspection and cleaning. In this case, for the aforementioned one-piece molded ferrule protective sleeve 103, additional tooling is often needed to complete the corresponding inspection and cleaning processes. However, the detachable connection between the ferrule protective sleeve 103 and the insertion end 101 eliminates the need for additional tooling; the ferrule end-face inspection and cleaning can be completed simply by removing the ferrule protective sleeve 103.

[0060] Furthermore, when using the optoelectronic connector after assembly, there may be situations where multiple connectors with different functions are used simultaneously. In this case, to avoid mismatch between different functional connectors on the wrong female connector, corresponding avoidance measures need to be designed. This is to prevent incorrect connector insertion and to avoid damage to the inner core assembly 2 and the internal structure of the female connector when incorrect connector insertion occurs. Therefore, in a preferred embodiment, a foolproof mechanism is preferably provided on the insertion end 101.

[0061] In actual installation, the foolproof mechanism includes a plurality of foolproof units 105 disposed on the outer periphery or end face of the plug-in end 101; and / or, the foolproof mechanism includes a non-rotating structure 106 disposed at the end of the plug-in end 101.

[0062] As a foolproof mechanism, it is preferable to configure the end of the plug-in terminal 101 in a foolproof form, for example, by configuring the end of the plug-in terminal 101 as a non-rotating structure 106. Correspondingly, a corresponding foolproof inner contour is provided inside the female connector to ensure that the plug-in terminal 101 can only be aligned with the inner hole of the female connector in a certain circumferential position, thereby completing the insertion. In this way, circumferential misalignment during optoelectronic connector insertion can be effectively avoided, and damage to the end face of the ferrule 210 can be prevented.

[0063] For example, in a feasible example, the end of the plug terminal 101 is configured as follows: Figure 1 The non-rotating structure 106 shown has a "D-shaped" cross-section.

[0064] As another approach to prevent misfitting, it is preferable to provide a misfitting unit 105 on the end face or end face structure of the plug end 101 to distinguish connectors with different functions and avoid misfitting of connectors with different functions.

[0065] For example, in such Figure 7In the preferred embodiment shown, a plurality of foolproof units 105 are provided on the outer periphery of the ferrule protective sleeve 103. These foolproof units 105 are formed on the end face of the insertion end 102. Their setting angle and spacing can be differentiated according to the different functions of the connector. For example, they can be arranged perpendicular to the surface of the ferrule protective sleeve 103 or at a 45° angle; or, for example, the plurality of foolproof units 105 can be arranged at 90° intervals or at 180° intervals. Thus, combined with the corresponding arrangement of the connector female head, mis-insertion between connectors with different functions can be avoided, ensuring the reliability of connector insertion.

[0066] It is understandable that, in actual installation, the plug-in end 101 of the outer casing 1 can be configured as a non-rotating structure 106, and multiple foolproof units 105 can be provided on the end face of the plug-in end 101, such as... Figure 12 As shown in the figure. At this time, the non-rotating structure 106 serves as the first-level foolproof mechanism to prevent the connector from being inserted into the female head; the foolproof unit 105 serves as the second-level foolproof mechanism to ensure the connector is properly aligned with the female head of the same specification but different functions, preventing the mis-insertion of cables with different functions.

[0067] More preferably, a plug-in locking mechanism 104 is provided on one side of the housing 1 for locking the plug end 101 after it is plugged into the corresponding female head. In actual installation, the plug-in locking mechanism 104 preferably does not protrude from the circular outline of the housing 1, so as to ensure that the housing 1 can be plugged into the female head with a circular inner cavity.

[0068] More preferably, in the preferred embodiment, the inner core 203 preferably includes an inner core body 2031 and an inner core metal insert 2032 disposed at both ends, with an inner hole connecting the two ends formed between them. Simultaneously, the inner core body 2031 has an inner core hole 2033 for mounting and embedding the tail end of the insert 201 and the spring 202, and an opening 2034 is formed on the outer periphery of the end of the inner core body 2031 connected to the inner core metal insert 2032. Subsequently, the optoelectronic composite cable 6 can be introduced into the inner hole through the inner core metal insert 2032 and crimped and fixed by the inner core metal insert 2032. Furthermore, the optical fiber unit 601 of the optoelectronic composite cable 6 can extend into the inner core hole 2033 and connect to the tail end of the insert 201, and the wire unit 602 can extend out from the opening 2034 in the middle of the inner core 203.

[0069] More preferably, in the preferred embodiment with inner shell 206, the opening 2034 on the outer periphery of inner core 203 can face the terminal through slot 2062 after inner core body 2031 is assembled with inner core through slot 2061, so that the wire unit 602 extending from the opening 2034 can be quickly connected to the power terminal 3 and embedded into the terminal through slot 2062.

[0070] In addition, the inner core assembly 2 in the preferred embodiment preferably includes a dust cap 204. The dust cap 204 can be inserted from the end of the ferrule protective sleeve 103 and sleeved on the ferrule end face of the ferrule 201 after the ferrule 201 is fully assembled, thereby fully realizing dust prevention and protection of the ferrule end face of the ferrule 201.

[0071] By utilizing the aforementioned configuration of the outer shell 1 and the inner core component 2, a photoelectric connector that can simultaneously meet the requirements of optical communication and power transmission can be obtained, thus satisfying the needs of automotive applications.

[0072] Based on the aforementioned optoelectronic connector configuration, as another aspect of this utility model, the following can be further obtained: Figure 12 The vehicle-mounted prefabricated optical cable structure shown is an optical composite cable with an optical connector at one end.

[0073] The vehicle-mounted prefabricated optoelectronic cable structure in the preferred embodiment includes an optoelectronic connector and an optoelectronic composite cable 6 connected thereto. The optoelectronic composite cable 6 in the preferred embodiment is as follows: Figure 13 As shown, it contains an optical fiber unit 601 and a wire unit 602.

[0074] As an example, the optical fiber unit 601 is preferably a tight-buffered optical fiber, and the outer periphery of the optical fiber unit 601 and the wire unit 602 is sequentially covered with aramid fiber 603 and an outer sheath 604.

[0075] During actual assembly, the optical fiber unit 601 and the wire unit 602 of the optoelectronic composite cable 6 are introduced from the tail end of the inner core 203. The optical fiber unit 601 extends along the inner hole and connects to the ferrule 201. The tail end of the ferrule 201, after being assembled with the spring 202, is embedded in one end of the inner core 203. The end of the inner core 203 with the ferrule 201 is assembled with the inner core through slot, so that the limiting protrusion in the middle of the ferrule abuts against the inner wall surface of the inner core through slot and provides axial limitation. Simultaneously, the wire unit 602 extends from the opening 2034 of the inner core 203 and connects to the power terminal 205. The power terminal 205 with the wire unit 602 connected is embedded and fixed in the terminal through slot.

[0076] Of course, it is understandable that in actual setup, the optoelectronic composite cable 6 assembled with the aforementioned optoelectronic connector can also be distinguished from... Figure 13 Other cable structures in the form of medium may also contain reinforcing components or other parts, as long as the relevant cable type can be assembled and the corresponding components do not affect the assembly of the corresponding unit. This can be optimized according to actual needs, and will not be elaborated here.

[0077] More preferably, to further ensure the stability of the tail end after the optoelectronic connector is installed, in actual installation, it is preferable to provide a connection between the inner core metal insert 2032 (the tail end of the inner core 203) and the optoelectronic composite cable 6. Figure 1 The sealing sleeve 4 shown has one end fitted onto the tail end of the inner core metal insert 2032, and the other end fitted onto the outer periphery of the optoelectronic composite cable 6. Subsequently, the tail sleeve 3 is fitted onto the outside of the sealing sleeve 4 and fixed to the inner core metal insert 2032.

[0078] As a feasible example, in the preferred embodiment, the sealing sleeve 4 is a heat shrink tubing, which can be first fitted onto the outer periphery of the inner core metal insert 2032 and the optoelectronic composite cable 6, and then shrunk by heating, so that both ends of the heat shrink tubing are tightly fitted onto the outer periphery of the inner core metal insert 2032 and the optoelectronic composite cable 6, thereby completing the fixation and sealing of the optoelectronic composite cable 6 at the inner core 203, and further improving the stability of the tail end of the optoelectronic connector.

[0079] In addition, it should be noted that the connection between the optical fiber unit 601 and the end of the ferrule 201 in the inner core assembly 2, and the connection between the wire unit 602 and the power terminal 205, all adopt mature processes in the existing technology, which will not be elaborated here.

[0080] For the optoelectronic prefabricated cable in the preferred embodiment, its design based on optoelectronic connectors can complete the connector setup through optoelectronic composite cable 6. It can not only use optical fiber transmission to replace conventional copper cable transmission, but also effectively achieve reliable power line setup, thereby meeting the application scenarios that require simultaneous power connection and signal transmission, such as the application scenarios of vehicle connectors, especially meeting the application requirements in intelligent connected vehicles, and fully ensuring the reliability of signal transmission and power transmission.

[0081] 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.
