[0020] In order to make the purpose, technical scheme and advantages of the utility model clearer, each embodiment of the utility model will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in each embodiment of the utility model, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can also be implemented. The division of the following embodiments is for the convenience of description and should not constitute any limitation on the specific implementation of the utility model. The various embodiments can be combined with each other and referenced to each other without contradiction.

[0021] The first embodiment of the present invention relates to Figure 1 , Figure 2A bundled coaxial optical cable structure of a lightweight imaging device is shown, comprising an optical fiber inner core 1 and an optical fiber cladding 2 wrapping the optical fiber inner core 1, the optical fiber cladding 2 is wrapped with a coating layer 4 on the outer circumference, and a plurality of copper core wires 3 and an optical fiber outer core parallel to the optical fiber cladding 2 are interspersed in the coating layer 4, and the copper core wires 3 are evenly distributed along the circumference of the optical fiber cladding 2; the optical fiber inner core 1 is a multimode optical fiber inner core; the number of copper core wires 3 and the optical fiber outer core is the same and is staggered.

[0022] Therefore, the multimode optical fiber line composed of the optical fiber inner core 1 and the optical fiber cladding 2 can transmit image data at high speed. At the same time, based on the setting of the copper core wire 3 and the optical fiber outer core, the cable connection can realize the cable transmission of the drive data, control data and other data that are not suitable for optical fiber transmission, so there is no need to make major changes to the optical fiber connection of the equipment. In addition, the optical fiber outer core forms signal isolation for the copper core wire 3, while providing a hardware channel to supplement the optical fiber communication, it also avoids signal interference between the copper core wires 3. In addition, the copper core wire 3 and the optical fiber outer core can play a certain supporting role for the multimode optical fiber line, thereby improving the overall service life. On the other hand, the multimode optical fiber line is suitable for short-distance high-speed data transmission, and the copper core cable connection is also suitable for short-distance high-speed data transmission. The integration of the two has an excellent synergistic effect. Overall, the integration is high, the communication connection functions are complete and diverse, the structure is reasonable and compact, and the market prospects are excellent.

[0023] The second embodiment of the present invention is substantially the same as the first embodiment, mainly in that the copper core wires 3 are 18 AWG28 ultra-fine copper core wires.

[0024] Furthermore, the copper core wires 3 form a cluster of coaxial cables. The cluster of coaxial cables is a cable connector form in the prior art for which standard parts are available, thereby significantly reducing the cost.

[0025] Furthermore, the copper core wire 3 and the optical fiber inner core 1 are connected to the same connector and the optical fiber connector and the coaxial connector are arranged separately, thereby improving the degree of integration.

[0026] Furthermore, the coating layer 4 is wrapped with a sleeve 5 .

[0027] Furthermore, a partition is fixed on the inner wall of the sleeve 5, and the partition is located at the midpoint of the copper core wire 3 and the outer core of the optical fiber. The partition can provide rigid support on the one hand, and is conducive to the assembly and positioning of the copper core wire 3 and the outer core of the optical fiber during the processing on the other hand.

[0028] Furthermore, there are positioning steps on the inner wall of the sleeve 5 at positions facing the copper core wire 3 and the outer core of the optical fiber to press against the corresponding copper core wire 3 and the outer core of the optical fiber.

[0029] Furthermore, the inner surface of the positioning step is a concave arc surface, and the shape of the concave arc surface matches the copper core wire 3 and the outer core of the optical fiber. The positioning table is mainly used to provide assembly positioning of the copper core wire 3 and the outer core of the optical fiber during processing and to provide position and structural stability of the copper core wire 3 and the outer core of the optical fiber during use.

[0030] Furthermore, the optical fiber cladding 2 and the coating layer 4 are interference fit.

[0031] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present invention, and in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present invention.
