Embodiment Construction

[0030] The multi-way optical fiber rotary connector of the present invention is as figure 1 As shown, it includes a Dove prism 1, a prism sleeve 2, a shaft end cover 3 and a collimator fixed end cover 4. The Dove prism 1 is accommodated and fixed in the prism sleeve 2, and the prism sleeve 2 Shaft end caps 3 are arranged at both ends of the shaft end cap 3, and a collimator fixed end cap 4 is arranged on the outer side away from the shaft end cap 3. The prism sleeve 2, the shaft end cap 3, and the collimator fixed end cap 4 are the same axis; as figure 2 , 3 , 4, the Dove prism 1 includes the same incident surface 11, exit surface 12 and reflection surface 15 as CN111487726A, the incident surface 11 is perpendicular to the exit surface 12, and the incident surface 11, exit surface 12. The normal of the plane where the reflective surface 15 is located is located on the same plane. The Dove prism 1 of the present invention is characterized in that it also includes a positioni...

Abstract

The invention belongs to the field of optical signal transmission, and particularly relates to a multi-path optical fiber rotary connector, which comprises a Dove prism and a prism sleeve. The Dove prism is accommodated and fixed in the prism sleeve; the Dove prism comprises an incident surface, an emergent surface and a reflecting surface, the Dove prism further comprises a positioning plane, and the positioning plane is connected between the incident surface and the emergent surface and is opposite to the reflecting surface; the prism sleeve comprises an inner surface, the inner surface is provided with an inner plane, and the inner plane is attached to the positioning plane. According to the multi-path optical fiber rotary connector, the assembly difficulty can be effectively reduced, and the assembly steps are reduced. Through the cooperation of the Dove prism, the prism sleeve, the shaft end cover and a collimator fixing end cover, an adjustment-free light rotary connector can be finally realized, the installation space of an adjustment device does not need to be considered, and the number of paths can be greatly improved under the condition of the same clear aperture.

Description

technical field [0001] The invention belongs to the field of optical signal transmission, and in particular relates to a multi-channel optical fiber rotary connector. Background technique [0002] Fiber Optic Rotary Joint (FORJ: Fiber Optic Rotary Joint), also known as fiber optic slip ring, fiber optic rotary joint, optical hinge, etc., is used to solve the problem of optical signal transmission between relative rotating parts, that is, to ensure that the transmission of optical signal And interrupt. Compared with traditional electrical connectors, optical fiber rotary connectors have the following advantages: use light for signal transmission, no electromagnetic leakage, good confidentiality, anti-electromagnetic interference; non-contact transmission, no wear, long life, up to 5 million revolutions ;No friction, can be used in flammable and explosive environments; the transmission bandwidth is much larger than that of electrical connectors, and the use of wavelength divi...
