Summary of the invention
The object of the present invention is to provide a kind of optical rotary joint, electric rotary connector right alignment be easy to ensure photoelectric composite-rotation connector.
In order to solve the problem, technical scheme of the present invention is:
Photoelectric composite-rotation connector, comprise optical rotary joint and electric rotary connector, the electric rotary connector rotor of electric rotary connector comprises the turning axle that axis extends along the longitudinal direction, optical rotary joint comprises coaxial cable and rotates the optical rotary joint stator and optical rotary joint rotor that are assembled together, the cable hole arranged with rotating shaft coaxle line is provided with in turning axle, optical rotary joint rotor has identical being fixedly assemblied in described cable hole with the coaxial load segment making optical rotary joint rotor and rotating shaft coaxle line arrange, optical rotary joint stator is fixedly connected with the electric rotary connector stator of electric rotary connector.
Optical rotary joint rotor is fixedly assemblied on turning axle by the fixed pin that Axis Extension direction is vertical with fore-and-aft direction.
Electric rotary connector stator comprises stator case and is arranged at the end cap of stator case front end, coaxial load segment is positioned at the front end of optical rotary joint rotor, described coaxial load segment is sleeve-like structure, the rear end coaxial cable of described optical rotary joint stator rotates and is assemblied in the endoporus of coaxial load segment, and the front end of described optical rotary joint stator is fixedly connected on described end cap.
Described end cap offers mounting hole, and the front end of described optical rotary joint stator is plugged in described mounting hole, and the front end of optical rotary joint stator is fixedly connected with mounting hole by key, keyway arrangements.
The outer peripheral face of described coaxial load segment offers the trough extended along the longitudinal direction.
Beneficial effect of the present invention is: the optical rotary joint rotor in the present invention realizes the right alignment requirement of optical rotary joint rotor and electric rotary connector rotor by the shaft hole matching of coaxial load segment and cable hole, and electric rotary connector stator and electric rotary connector rotor are that coaxial cable is rotatably assorted, optical rotary joint stator and optical rotary joint rotor are that coaxial cable is rotatably assorted, therefore just ensure that optical rotary joint, the right alignment requirement of electric rotary connector, the right alignment of shaft hole matching more easily realizes, therefore optical rotary joint, the right alignment of electric rotary connector is easy to ensure, whole photoelectric composite-rotation connector product is easy to make.
Further, the rear end coaxial cable of optical rotary joint stator rotates and is assemblied in the endoporus of coaxial load segment, that is direct larger coaxial load segment and cable hole shaft hole matching, whole like this optical rotary joint rotor can load in cable hole completely, and the rear end of optical rotary joint stator also can be arranged in cable hole because stretching in coaxial load segment, that is whole optical rotary joint only has the front end of optical rotary joint stator to be positioned at outside turning axle, greatly reduces the axial dimension of photoelectric composite-rotation connector like this.
Accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of the present of invention.
Embodiment
The embodiment of photoelectric composite-rotation connector is as shown in Figure 1: comprise optical rotary joint and electric rotary connector, optical rotary joint comprises coaxial cable and rotates the optical rotary joint stator 10 and optical rotary joint rotor 1 that are assembled together, optical rotary joint stator 10, arrange before and after optical rotary joint rotor 1, electric rotary connector comprises the electric rotary connector stator and electric rotary connector rotor that coaxial cable is assembled together, electric rotary connector stator comprises stator case 4 and is arranged at the end cap 8 of stator case 4 front end, electric rotary connector rotor comprises the turning axle 11 that axis extends along the longitudinal direction, turning axle is arranged at intervals with vertically multiple conducting ring 2, electric rotary connector stator is provided with the conduction brush 3 coordinated with conducting ring conductive contact, the cable hole 12 arranged with rotating shaft coaxle line is provided with in turning axle.The front end of optical rotary joint rotor has identical being assemblied in cable hole 12 with the coaxial load segment 7 making optical rotary joint rotor 1 and turning axle 11 be coaxially set, coaxial load segment 7 is positioned at cable hole 12 completely, the outer peripheral face of coaxial load segment 7 offers the trough 5 extended along the longitudinal direction, optical rotary joint rotor is fixedly assemblied on turning axle 11 by the fixed pin 6 that Axis Extension direction is vertical with fore-and-aft direction, coaxial load segment is sleeve-like structure, the rear end of rotary connector stator 10 is rotated by coaxial bearing line and is assemblied in the endoporus of coaxial load segment, fixed pin is then between two bearings, the front end of optical rotary joint stator is fixedly connected on end cap 8, end cap offers mounting hole, the front end of optical rotary joint stator is plugged in mounting hole, key is passed through in the front end of optical rotary joint stator, keyway arrangements 9 is fixedly connected with mounting hole, key, keyway arrangements comprises the keyway be arranged on optical rotary joint stator and end cap and the key be plugged in keyway.
