Detachable optical fiber signal rotary transmission device

Abstract

The invention provides a detachable optical fiber signal rotary transmission device. The detachable optical fiber signal rotary transmission device comprises a detachable optical fiber signal rotary transmission device body, a toggle screw (1), a collimation butt joint positioning block (2), a rotary threaded sleeve (4), an optical fiber fixing block (5), a bearing (6) and an optical fiber (10),wherein the toggle screw (1) is fixedly connected with the collimation butt joint positioning block (2); the optical fiber (10) includes an optical fiber collimation member; the collimation butt joint positioning block (2) tightly supports theoptical fiber collimation member. The rotary threaded sleeve (4) is connected with the optical fiber fixing block (5); and the inner ring of the bearing (6) isconnected with the collimation butt joint positioning block (2). The technical means of combining rigid contact and flexible contact is adopted, the technical problem of connection between the optical fiber and the metal sleeve which rotate relatively is solved, and the technical effects that the metal sleeve effectively restrains the two sections of optical fiber collimators, and an optical fiber transmission path is formed in relative rotation are achieved.

Description

technical field [0001] The invention relates to the technical field of optical fiber signal transmission, in particular to a detachable optical fiber signal rotary transmission device. Background technique [0002] At present, the optical fiber transmission devices on the market can be roughly divided into two types: one is to use two parts with high coaxiality requirements to rigidly fix two optical fibers respectively to realize optical fiber signal transmission; the other is to use them in ceramic catheters. Strong glue bonding, at the same time, flexible constraints fix two bare optical fibers to realize optical fiber signal transmission. The disadvantage of the first type of optical fiber transmission device structure is that for the two different parts where the fixed optical fiber is installed, the processing accuracy is particularly high. According to the data, the distance deviation and angle deviation between the two transmission optical fibers will increase the lo...

Problems solved by technology

The disadvantage of the first type of optical fiber transmission device structure is that for the two different parts where the fixed optical fiber is installed, the processing accuracy is particularly high. According to the data, the distance deviation and angle deviation between the two transmission optical fibers will increase the loss value. Often, on the premise that the two parts meet the accuracy requirements, the deviation between the two optical fibers will also be caused by the installation error, which will affect the transmission accuracy.

The structural disadvantage of the second type of optical fiber transmission device is that: bare fiber is used as the transmission medium, there is no reliable metal positioning surface, and it can only be bonded with strong glue. The whole piece is scrapped together, and the economy is poor

In this patent, two optical fiber collimators that rotate relatively are fixed in two brackets that rotate relatively; factors such as the machining accuracy of the holes of the two brackets, bearing clearance, bearing installation deviation, and component bearing position processing errors will affect the optical fiber. The effect of transmission loss
