Problems solved by technology

[0012] However, in the connecting device for rotating an optical fiber such as Patent Document 4, when the optical fiber cable is connected, the outer casing that does not rotate connects the inner rotating optical fiber. There is a possibility that the shaft support member may be damaged due to a push-in load. In the case of providing a clearance for rotation between the outer casing and the inner rotating member as in Patent Document 3, there is a possibility that the casing may not be connected even if the casing is connected. The internal connector may not be completely connected, and the connection effect is not good
In addition, when the shaft support member is a disk-shaped flange, since the rotating flange contacts the non-rotating part, there is a possibility of causing problems such as deformation due to friction.

Embodiment 1

[0042] 1. Appearance and structure of optical interference tomography diagnostic device

[0043] figure 1 It is a diagram showing the external configuration of the optical interference tomography diagnostic apparatus 100 to which the connecting device according to the first embodiment of the present invention is applied.

[0044] Such as figure 1 As shown, the optical interference tomography diagnostic apparatus 100 has a detachable photodetector, that is, a catheter part 101, a scanner / pullback part 102, and an operation control device 103. The scanner / pullback part 102 and the operation control device 103 pass through the signal line 104 connections.

[0045] The catheter part 101 is directly inserted into the blood vessel, by using the imaging fiber core (refer to figure 2 , image 3 ) to measure the state of the inside of the blood vessel with low-interference light irradiated. The scanner / pullback section 102 performs radial scanning of the optical imaging core with...

Embodiment 2

[0109] Figure 17 It is a figure which shows the connector device in 2nd Embodiment of the connector device of this invention. Such as Figure 17 As shown, in this embodiment, the elastic member 409 that presses the disk-shaped flange 407 when the optical fiber cable is connected is replaced with a metal coil spring 1701 . The coil spring 1701 has a cylindrical pusher 1702 at its end, and the pusher 1702 pushes the disc-shaped flange 407, thereby connecting the optical fiber. Any material may be used as the forming material of the coil spring 1701 as long as it can exhibit elasticity.

Abstract

Provided is a coupling device for coupling optical fiber cables, wherein contact with the internal parts is reduced when coupling a connector, and the coupling is simplified. When a projection 1101 of a connector device housing is slid along a groove 1001 and is positioned at the deepest part of the groove 1001 during the insertion of the projection 1101 into an adapter device groove 1001 of an adapter device housing 601, the coupling device which connects optical fiber cables compresses an elastic member, and connects an optical fiber connector of the connector device and the optical fiber end on the adapter device side.

Description

technical field [0001] The present invention relates to a connecting device for connecting optical fiber cables and its constituent parts. Background technique [0002] In recent years, due to the development of large-capacity communications and the like, the demand for connectors for optical fibers has been increasing as a connecting device for connecting optical fiber cables around the field of communications. Specific examples of connectors for optical fibers include FC connectors, SC connectors, MU connectors, and the like. [0003] These connectors have a mechanism for preventing relative rotation between the optical fiber cables in order to prevent the ends (contact surfaces) of the connected optical fiber cables from being damaged. For example, in the case of FC connectors, rotation in the circumferential direction is avoided by pins and grooves; in the case of SC connectors and MU connectors, rotation in the circumferential direction is avoided by using the shapes o...
