Description

Technical Field

[0001] The invention relates to the technical field of connectors, and in particular to a vehicle-mounted optoelectronic hybrid connector assembly. Background Art

[0002] With the development of automobile intelligence and networking, the total bandwidth requirements for automobile communications are getting higher and higher. The use of a large number of on-board sensors and display screens has higher requirements for the complexity, volume, weight and electromagnetic shielding design of automobile wiring harnesses. Optical fiber has become an ideal carrier for on-board high-speed communication due to its small size, low weight and immunity to electromagnetic interference. On-board optical fiber communication technology can also provide better communication connection and bandwidth support for data transmission of automobile automatic driving and intelligent cockpit. However, the realization of on-board optical fiber communication is inseparable from the support of electricity, so the optoelectronic hybrid connector has become a necessary carrier for the realization of on-board optical communication. Therefore, with only 9um glass optical fiber, how to meet the high strength in the complex assembly process of on-board wiring harnesses, the high vibration and complex application scenarios during the driving of the car, and how to ensure the stable end-to-end transmission of optical fiber in a complex environment. This is undoubtedly an improvement in the requirements for design, processing and manufacturing. In particular, there are two difficulties for glass optical fiber: first, only when the end face to the end face can be kept in contact at all times in the transfer structure can the quality of optical fiber transmission performance be guaranteed; second, the transmission of optical fiber has high environmental requirements. Dust, impurities, etc. will affect the transmission of signals, and the quality of the optical fiber channel must be guaranteed under the influence of the harsh environment of the car. How to solve the above two problems while ensuring high transmission frequency becomes the key.

[0003] The prior art patent with publication number CN117810748A discloses an optoelectronic hybrid connector and a plug connector. The optoelectronic hybrid connector includes a plug and a socket. The socket includes a socket housing, a socket insulator and a cover housing assembled in the socket housing. The cover housing is provided with an optical contact jack and an electrical contact jack. The side of the optical contact jack is connected to an open groove axially penetrating the surface of the cover housing. The plug includes a plug housing, a tail sleeve and a plug inner core. The plug inner core is located in a cavity formed by the plug housing and the tail sleeve. The plug inner core includes an inner core housing and an inner core component. The inner core housing is connected to the tail sleeve. The inner core housing is provided with a locking protrusion that passes through the plug housing for locking the socket. The inner core component includes a crimping assembly and an insulator component. The plug connector is a plug in an optoelectronic hybrid connector. The above-mentioned optoelectronic hybrid connector can transmit fluorescent and electrical signals at the same time. However, in a high vibration environment, the optical contact will shake in the housing and the optical fiber transmission will be unstable, which affects the use of the connector. Summary of the invention

The head of the pressure plate 82 is located at the lower side of the female end hook 291. After the connectors are plugged in, the CPA structure 8 is pushed to move for secondary locking. At this time, the positioning block 211 passes over the lower locking block 812 to reach the lower side of the lower locking block 812, and the pressure plate 82 passes over the hanging platform 110 and the female end hook 291 under the guidance of the lower side inclined surface of the hanging platform 110 to reach the upper side of the female end hook 291, and the support plate 83 reaches between the tail of the hanging arm 29 and the outer wall of the female end shell 21. The support plate 83 limits the movement of the hanging arm 29, thereby realizing the secondary locking of the connector.

[0039] Furthermore, the male housing 11 is provided with an anti-error guide strip 19, and the female housing 21 is provided with an anti-error guide groove 28, and the anti-error guide strip 19 is slidably matched with the anti-error guide groove 28. The anti-error guide strip 19 and the anti-error guide groove 28 are arranged along the plug-in direction of the connector, which facilitates the quick connection of the connector assembly.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
