Abstract
Description
Technical Field
[0001] The utility model relates to the field of optoelectronic technology, in particular to a cable device for an optical fiber delay line. Background Art
[0002] A fiber optic delay line is a device that uses optical fiber as a transmission medium to achieve signal delay. An extender is usually connected to one end of the fiber optic delay line.

The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.
[0028] Example 1
[0029] Reference Figure 1-Figure 7 , which is the first embodiment of the present utility model, provides a cable device for an optical fiber delay line. The cable device for an optical fiber delay line includes a main body component 100, a clamping component 200 and a moving component 300. The three can cooperate to gather scattered optical fiber delay lines.
[0030] Specifically, the clamping assembly 200 includes a clamping part 201, including a clamping block 201a, a movable bar 201b and a turntable 201c. There are two movable bars 201b, both of which are arranged at one end of the clamping block 201a. The clamping block 201a is arranged at one end of the movable bar 201b. The inner wall of the clamping block 201a is provided with a first placement groove 201a-1. The turntable 201c is arranged at one end of the clamping block 201a. The inner wall of the turntable 201c is provided with a second placement groove 201c-1. The inner wall of the turntable 201c is provided with a movable groove 201c-2. The movable bar 201b slides on the inner wall of the movable groove 201c-2. The outer ring of the turntable 201c is provided with a tooth block 201d.
[0031] When the optical fiber delay line 103 needs to be stored, the optical fiber delay line 103 is placed in the inner walls of the first placement groove 201a-1 and the second placement groove 201c-1, and then the turntable 201c is rotated. The rotation of the turntable 201c drives the movable bar 201b to move on the inner wall of the movable groove 201c-2. The movement of the movable bar 201b drives the clamping block 201a to move toward each other. The clamping block 201a moves to clamp the optical fiber delay line 103, so that the optical fiber delay line 103 can be fixed, so that the optical fiber delay line 103 can be stored neatly and not placed in a disorderly manner.

The movement of the protective ring 302k squeezes the retraction rod 302l to shrink it, making the connecting shaft 302h more stable when sliding.
[0050] Specifically, a limiting frame 302n is provided on one side of the first moving rod 301b, and an inclined groove 302n-1 is opened on the inner wall of the limiting frame 302n. A limiting rod 302o is provided on one side of the inclined groove 302n-1. A fixed block 302p is sleeved on one end of the limiting rod 302o, and a fixed shaft 302q is inserted into the inner wall of the fixed block 302p.

When the limiting rod 302o moves, it will squeeze the torsion spring 302r, and then adjust the movement of the optical fiber delay line 103. After the adjustment is completed, by releasing the pulling rod 302s, the limiting rod 302o and the inclined groove 302n-1 are re-engaged by the rebound force of the torsion spring 302r, so that it can be limited.
[0052] Specifically, the fixing block 302p is fixed to one side of the support plate 202c, and a protective frame 302u is sleeved on the outer side of the fixing plate 302a.
[0053] The limiting frame 302n is located on the inner wall of the protection frame 302u. The fixing plate 302a is used to support the support plate 202c. The support plate 202c is also used to support the fixing block 302p. The protection frame 302u is used to protect the support plate 202c.
[0054] Specifically, it also includes a main component 100, including an optical fiber extender 101, an optical fiber interface 102 and an optical fiber delay line 103.

[0056] When in use, the optical fiber delay line 103 is placed in the inner wall of the first placement groove 201a-1 and the second placement groove 201c-1, and the limit is first released. By pulling the pulling rod 302s, the pulling rod 302s will drive the limit rod 302o to separate from the inclined groove 302n-1.

The movement of the movable bar 201b drives the clamping block 201a to move toward each other. The clamping block 201a moves to clamp the optical fiber delay line 103, and then limits it to prevent the support plate 202c from retracting. At this time, the pulling rod 302s is released. At this time, the rebound force of the torsion spring 302r causes the limiting rod 302o to re-engage with the inclined groove 302n-1, so that it can be limited. In this reciprocating manner, the optical fiber delay line 103 is completed.
