Therefore, the utility model is not intended to be limited to the embodiments shown, but is consistent with the widest range of principles and features disclosed in the present application.

[0033] In order to achieve optical-electrical simultaneous transmission and strong signal stability, according to Figure 1-Figure 3 As shown, the utility model provides a coaxial optoelectronic hybrid connector, including a housing assembly 1, an optical fiber ferrule 2, and a limiting member 3; the optical fiber ferrule 2 is coaxially limited in the housing assembly 1 by the limiting member 3, so that the housing assembly 1 transmits electrical signals while the optical fiber ferrule 2 realizes optical transmission.

[0034] In a specific implementation scheme, the housing assembly 1 is composed of a multi-layer circular housing; the optical fiber is cut into an end face by a cross-section cutting process, and then inserted into the optical fiber ferrule 2 and fixed with optical fiber special glue, so that the entire connector is easy to install and process. The stopper 3 is used to press the optical fiber ferrule 2 and ensure that it is tightly plugged.

[0035] In more detail, according to Figure 1 , Figure 3 As shown, the housing assembly 1 includes an outer conductor 11, an insulator 12, and an inner conductor 13 which are coaxially arranged in sequence from the outside to the inside; the outer conductor 11 is fixedly engaged with the insulator 12, the insulator 12 is sleeved on the inner conductor 13, the insulator 12 is a circular sleeve structure, and a clamping ring 12a is coaxially provided on the side close to the handle of the optical fiber ferrule 2, so that the clamping ring 12a is engaged with the groove 11a on the inner wall of the outer conductor 11 to clamp and fix the insulator 12 to the outer conductor 11, and the insulator 12 and the clamping ring 12a can be integrally formed.

[0036] The outer conductor 11 is a metal shell, which provides structural protection and installation positioning functions; the insulator 12 is used to electrically insulate the inner conductor 13 and the outer conductor 11, and ensure that the inner conductor 13 and the outer conductor 11 are coaxial. Furthermore, the outer conductor 11 includes a first shell 11b and a second shell 11c fixedly connected by rivet claws; the cross-sectional structures of the first shell 11b and the second shell 11c are both arc-shaped, so that the first shell 11b and the second shell 11c are fixedly connected to form a cylindrical structure with a circular cross-sectional structure.
