Description

Technical Field

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

[0002] In the automotive industry, wiring harnesses form the core of the automotive circuit network and play a vital role in the operation of the vehicle system. With the development of automotive electronics technology, the number of electronic devices in cars is increasing, and the performance requirements for wiring harnesses are also becoming more stringent. Traditional wires (coaxial cables) are no longer sufficient to meet the requirements of modern automobiles for data transmission speed and interference resistance.

[0003] Taking a single 4K camera as an example, the data transmission rate at 60FPS can exceed 10Gbps, and LiDAR can reach 1Gbps. The total bandwidth requirement of the vehicle's backbone network is expected to reach 25-50Gbps. Faced with such a huge data transmission demand, traditional copper cable communication methods are no longer sustainable, suffering from bandwidth bottlenecks, complex wiring, excessive weight, and insufficient anti-interference capabilities, making it difficult to meet the data transmission needs of intelligent connected vehicles.

[0004] 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 transmission 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 differ in the intelligent vehicle sector. This means that mature technologies from other fields often cannot be directly applied to automobiles, requiring targeted design and modifications. Furthermore, the numerous locations in a vehicle requiring wiring harnesses, and the different objects they need to conduct, necessitate the design of separate connectors for each location to meet power and signal transmission requirements. This makes the connector design and manufacturing process extremely complex, requiring separate design, mold making, and production for each connector, resulting in relatively high production and application costs.

[0025] Below, for reference Figures 1-8 This invention describes a vehicle-mounted optoelectronic composite connector according to a preferred embodiment of the present invention.

[0026] like Figure 1 , Figure 2 As shown, the vehicle-mounted optoelectronic composite connector in the preferred embodiment includes a male connector 1, a female connector 2, and a terminal assembly. The male connector 1 and the female connector 2 can be connected via insertion, and the terminal assembly includes several optical terminal assemblies 3 and several electrical terminal assemblies 4.

[0027] Specifically, the optical terminal assembly 3 includes a male optical terminal unit 301 and a female optical terminal unit 302, which can be respectively connected to an optical fiber, such as... Figure 6 As shown; the electrical terminal assembly 4 includes a male electrical terminal unit 401 and a female electrical terminal unit 402 that can be connected to electrical wires respectively, as shown. Figure 7 As shown in the image.

[0028] At the same time, such as Figure 4As shown, the male connector 1 includes a male connector housing 101 with a plug-in portion 102. The male connector housing 101 is provided with a plurality of first terminal holes 103. Both the male connector optical terminal unit 301 and the male connector electrical terminal unit 401 can be inserted into any of the first terminal holes 103 and fixed.

[0029] Accordingly, such as Figure 5 As shown, the female connector 2 includes a female connector housing 201 with a insertion cavity 202. The female connector housing 201 is provided with the same number of second terminal holes 203 as the first terminal holes 103, and each second terminal hole 203 can be coaxially aligned with each first terminal hole 103 when the insertion part 102 is inserted into the insertion cavity 202. Both the female connector optical terminal unit 302 and the female connector electrical terminal unit 402 can be embedded in any of the second terminal holes 203 and fixed.

[0030] For the aforementioned male connector 1 and female connector 2, the type of terminal unit embedded in each second terminal hole 203 corresponds to the type of terminal unit embedded in each first terminal hole 103.

[0031] It should be noted that the aforementioned "terminal unit type correspondence" refers to the following: when the insertion part 102 is inserted into the insertion cavity 202, the second terminal hole 203, which is coaxially aligned with the first terminal hole 103 where the male optical terminal unit 301 is provided, is fitted with a female optical terminal unit 302; similarly, the second terminal hole 203, which is coaxially aligned with the first terminal hole 103 where the male electrical terminal unit 401 is provided, is fitted with a female electrical terminal unit 402. Thus, after the insertion part 102 and the insertion cavity 202 are properly inserted, all terminal components in the connector can be inserted and connected.

[0032] By utilizing the corresponding design of optical terminal assembly 3 and electrical terminal assembly 4, the number and position of the two types of terminal assemblies in the male housing 101 and female housing 201 can be adjusted as needed to meet the conduction setting requirements in different application scenarios.

[0033] In actual setup, the number of optical terminal components 3 configured in the vehicle-mounted optoelectronic composite connector is preferably not less than the number of terminal holes opened in any housing. In this way, the use state can be switched from having a single optical terminal component 3 in the connector (the rest being electrical terminal components 4 or empty) to having optical terminal components 3 in each terminal hole in the connector (the number of electrical terminal components 4 is zero).

[0034] by Figure 4 , Figure 5 In the example shown, each housing has four terminal holes. In this case, the terminal assemblies in the connector can be configured as follows: four optical and zero electrical, three optical and one electrical, two optical and two electrical, or one optical and three electrical. For example, in the illustration, it is a two-optical-two-electric configuration that includes two optical terminal assemblies 3 and two electrical terminal assemblies 4.

[0035] Of course, in special cases, a "zero-light, four-electric" configuration may also exist. Moreover, in some special cases, the number of terminal assemblies in the housing may be less than the number of terminal holes, which is equivalent to leaving some terminal holes empty, with the connector's conductivity achieved only by the terminal assemblies located in the corresponding terminal holes.

[0036] To meet the diverse application requirements of the connectors, in actual installations, the paired male connector 1 and female connector 2 are equipped with optical terminal assemblies 3 and electrical terminal assemblies 4, each with the same number of terminal holes as the male connector 1 and female connector 2. At the application site, the appropriate number of optical terminal assemblies 3 and electrical terminal assemblies 4 can be selected as needed to ensure the optoelectronic composite connector meets the application requirements of different scenarios. Before use, each terminal assembly is preferably installed independently of the two housings, and the appropriate number and type of terminal assemblies can be selected as required.

[0037] Furthermore, a first locking hole 104 is formed on the outer periphery of the male connector housing 101, and a second locking hole 204 is formed on the outer periphery of the female connector housing 201. A first locking member 5 is provided corresponding to the first locking hole 104, and a second locking member 6 is provided corresponding to the second locking hole 204. Depending on the configuration requirements and the number of terminal assemblies, the number of the aforementioned first locking member 5 and second locking member 6 can be varied accordingly, for example, in... Figure 3 In the preferred embodiment shown, two locking elements are arranged opposite each other, and corresponding locking holes are respectively opened on both sides of the two housings.

[0038] Correspondingly, each terminal unit (optical terminal unit and / or electrical terminal unit) embedded in the first terminal hole 103 can be axially locked by the first locking member 5 embedded in the first locking hole 104, and each terminal unit (optical terminal unit and / or electrical terminal unit) embedded in the second terminal hole 203 can be axially locked by the second locking member 6 embedded in the second locking hole 204.

[0039] Specifically, the male optical terminal unit 301 has a first locking groove 303 on its outer periphery, and the female optical terminal unit 302 has a second locking groove 304 on its outer periphery; the male electrical terminal unit 401 has a third locking groove 403 on its outer periphery, and the female electrical terminal unit 402 has a fourth locking groove 404 on its outer periphery.

[0040] More preferably, the first locking member 5 and the second locking member 6 are both limit cards that can be snapped into the corresponding locking slots, and in the optical terminal assembly 3 and electrical terminal assembly 4 that are plugged in and connected, the distance between the first locking slot 303 and the second locking slot 304 is equal to the distance between the third locking slot 403 and the fourth locking slot 404.

[0041] In actual setup, the distance between the first locking groove 303 and the end of the male optical terminal unit 301 to be inserted is equal to the distance between the third locking groove 403 and the end of the male electrical terminal unit 401 to be inserted. This setup ensures that, given the identical configuration of each first terminal hole 103, both the male optical terminal unit 301 and the male electrical terminal unit 401 can be properly inserted into the first terminal hole 103, aligning their respective locking grooves with the first locking hole 104 on the male connector housing 101. This allows the first locking member 5 to accurately engage in the first locking groove 303 or the third locking groove 403.

[0042] Furthermore, for the female optical terminal unit 302 and the female electrical terminal unit 402, their ends need to be respectively embedded in the first terminal hole 103 for alignment when the male connector 1 and the female connector 2 are inserted, and to be connected with the corresponding male optical terminal unit 301 and male electrical terminal unit 401. Since the actual insertion depth of the female optical terminal unit 302 and the female electrical terminal unit 402 can be optimized as needed, in actual installation, the distance between the second locking groove 304 and the end of the terminal unit to be inserted and the distance between the fourth locking groove 404 and the end of the terminal unit to be inserted are not specifically designed, as long as it can be ensured that both types of terminal components can be connected when the male connector 1 and the female connector 2 are inserted.

[0043] Based on the above design of the locking grooves on the two types of terminal assemblies, the two types of terminal assemblies can be interchanged in different terminal holes without affecting the alignment and insertion between male head 1 and female head 2, and ensure that each terminal assembly in male head 1 and female head 2 can be inserted and connected.

[0044] Furthermore, in actual installation, the main structures of the male optical terminal unit 301 and the female optical terminal unit 302 are preferably the same. Both types of optical terminal units preferably include an optical terminal housing 305, a ferrule 306, and a spring (not shown in the figure); one end of the optical terminal housing 305 is used to connect the optical cable and introduce the optical fiber, and the other end is used to embed the spring and the ferrule 306 assembled with the spring at the tail end.

[0045] In actual installation, the optical terminal housing 305, insert 306, spring, and other components in the male optical terminal unit 301 and the female optical terminal unit 302 are completely identical. The locking slots (i.e., the first locking slot 303 and the second locking slot 304) on the optical terminal housing 305 are also in the same position. This design simplifies the manufacturing process of the optical terminal unit, facilitates the replacement of the two types of optical terminal units, and further improves the ease of installation and use of the optical terminal assembly 3.

[0046] More specifically, the optical terminal assembly 3 also includes a ceramic sleeve 307, which can be fitted onto the front end of the insert 306 of the male optical terminal unit 301, so that the end face of the insert is hidden in the ceramic sleeve 307. At the same time, the ceramic sleeve 307 can be axially limited in the first terminal hole 103 when the male optical terminal unit 301 is inserted into the first terminal hole 103, and can allow the front end of the insert 306 of the female optical terminal unit 302 to extend into the ceramic sleeve 307 when the male and female terminals 1 are inserted, thereby completing the conduction of the inserts 306 of the two optical terminal units in the ceramic sleeve 307.

[0047] Furthermore, in the preferred embodiment, the electrical terminal assembly 4 is as follows: Figure 8 As shown in the figure. One end of the male electrical terminal unit 401 is a power receiving end, and the other end has a power receiving sleeve hole 405. At the same time, one end of the female electrical terminal unit 402 is a power receiving end for connecting wires, and the other end is provided with a conductive part 406. The conductive part 406 can conduct electricity between the two electrical terminal units after being inserted into the power receiving sleeve hole 405.

[0048] In detail, the male electrical terminal unit 401 can be axially fixed in the first terminal hole 103; the female electrical terminal unit 402 can be axially fixed in the second terminal hole 203, so that the conductive part 406 extends into the insertion cavity 202; then the conductive part 406 can extend into the electrical sleeve hole 405 when the male head 1 and the female head 2 are inserted, and realize the conduction between the male electrical terminal unit 401 and the female electrical terminal unit 402.

[0049] Furthermore, in the preferred embodiment, the first terminal hole 103 and / or the second terminal hole 203 are preferably stepped holes forming a limiting step surface, and the front end of the terminal unit that can be embedded in the corresponding terminal hole is provided with an annular step surface, which can abut against the limiting step surface when the terminal unit is embedded in the corresponding terminal hole. In this way, each terminal unit can be quickly embedded in the corresponding terminal hole, which facilitates the alignment and locking of the first locking member 5 and the second locking member 6.

[0050] Preferably, to facilitate the connection of wires at the ends of each electrical terminal, in one feasible example, the receiving end of each electrical terminal is preferably configured as a sleeve with a wedge-shaped notch at the end, so that the wire can be soldered to the sleeve after being inserted into the sleeve. Alternatively, in another feasible example, a crimping part is preferably provided at the receiving end of each electrical terminal, so that the wire can be crimped and fixed at the crimping part.

[0051] More preferably, a locking hook 105 is provided on the insertion part 102 of the male connector 1, and a locking slot 205 is provided in the insertion cavity 202 of the female connector 2, so that the locking hook 105 can engage with the locking slot 205 after being inserted into the insertion part 102 and the insertion cavity 202, thereby ensuring reliable locking after the male connector 1 and the female connector 2 are inserted, and ensuring the reliability of the connector.

[0052] Further preferably, in the preferred embodiment, the male connector 1 further includes a first sealing ring 106, which can be sealed to one end of the male connector housing 101 away from the insertion part 102, and the first sealing ring 106 has a number of first through holes equal to the number of terminal assemblies, which are used to seal and fit with the tail end of the male connector optical terminal unit 301 or the tail end of the male connector electrical terminal unit 401.

[0053] Similarly, in the preferred embodiment, the female connector 2 may also preferably include a second sealing ring 206. The second sealing ring 206 can be sealed and connected to one end of the female connector housing 201 away from the insertion cavity 202. The second sealing ring 206 has a second through hole with the same number as the terminal assembly. The second through hole is used to seal and fit with the tail end of the female connector optical terminal unit 302 or the tail end of the female connector electrical terminal unit 402.

[0054] By using the corresponding sealing rings at the tail ends of the male head housing 101 and the female head housing 201, the end sealing of the male head 1 and the female head 2 after corresponding assembly can be achieved, ensuring the performance of the male head 1 and the female head 2.

[0055] The vehicle-mounted optoelectronic composite connector of this utility model has a simple structure and is easy to assemble and disassemble. It can meet the requirements of simultaneous optoelectronic transmission. Through the corresponding arrangement of optical terminal components and electrical terminal components, the number and position of the two types of terminal components in the connector can be flexibly replaced according to application needs. This allows the connector to be used in different application scenarios, greatly improving the application flexibility and compatibility of the connector. In particular, it meets the application requirements of the vehicle-mounted application environment with a large number of connectors and diverse application needs. It can meet the ever-expanding data transmission volume in the vehicle-mounted environment, reduce the application cost of optoelectronic connectors, and has excellent practical value and application effect.

[0056] 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.
