JPS5962814A - Clamping method of optical fiber coating part and its mechanism - Google Patents

Abstract

PURPOSE:To improve the workability, by providing a detecting part which detects the depression of an optical fiber coating part and operating automatically a clamp to clamp the optical fiber coating part. CONSTITUTION:When a clamp plate 2 is left open, a detecting part 7 is projected from a clamp base 3 and is still. When an optical fiber core is brought onto the clamp base 3 and is depressed, the detecting part 7 is depressed. The clamp plate 2 is rotated in the direction of an arrow A in accordance with this depression, and the center of gravity is moved, and the clamp plate is rotated naturally in such direction that the optical fiber core is clamped furthermore. Then, the clamp plate is attracted by a magnet, and the optical fiber core is clamped between the clamp plate and the clamp base. Thus, the optical fiber core is clamped easily, and the workability is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) [Technical Field] The present invention mainly relates to a method of clamping an optical fiber core wire of an optical fiber joint reinforcing device and its structure.

(b) [Technical Background] Conventionally, the method of tightening optical fiber connections has been by using heat shrinkable tubes, and heaters for this purpose have been put into practical use. However, when setting the optical fiber through the heat shrink tube into the heater, I hold both ends of the optical fiber with my fingers, so I had to temporarily hold the optical fiber before clamping. A temporary holding part using a plate spring or the like was required to hold the device in place. Usually, a tension test is performed before reinforcement, so the clamp needs to be stronger than the tension test level of 2001 or higher, and after temporarily holding it with a leaf spring, the optical fiber core is further clamped with the main clamp. . As described above, the conventional methods and devices have the disadvantage that the clamping operation is required in two stages.

FIG. 1 is a perspective view showing an example of a conventional clamp device, in which an optical fiber 1 is placed on a clamp stand 3, one end of which is temporarily held by a leaf spring 5, and the lamp plate 2 is lowered. It was clamped between it and the clamp plate. 3
The magnet is used to bring the clamp plate and clamp stand into close contact.

The present invention overcomes these drawbacks and provides an ideal lamp method and apparatus.

(c) [Disclosure of the invention] The features of the present invention will be explained using figures.

FIG. 2 is a perspective view showing the configuration of an example of the device of the present invention, showing the clamp plate 8 and the detection section 7J that is a part of the clamp plate 8.
Clamp base 3, magnet 4, rotating shaft 8-C
↓II has been completed. As shown in Figure 2 (a),
When the clamp plate 2 is opened, the detection part 7 is in a static position 112 protruding from the clamp base 3. In such a state, when the -C1 optical fiber is brought and pushed down, the detection unit 7 is pushed down.

At this time, the clamp plate rotates in the direction of arrow A in conjunction with this, and as the center of gravity further moves, it naturally rotates in the direction of more clamping. As a result, the optical fiber core wire is clamped between the clamp plate and the clamp base as the clamp plate is attracted by the magnet. As has been explained hereafter, the method of the present invention has the advantage that by using the structure, the optical fiber can be easily clamped, and the manufacturing process is greatly improved. .

Although the detection part and the clamp plate of the present invention are connected by a rotating shaft, the connection between the detection part and the clamp is not limited to this, and it is possible to use a part of the clamp plate as the detection part. It may be done electrically; for example, the detection section may be a clamp switch, and the clamp may be operated electrically by pressing down the detection section with a seven-eye bar, without detracting from the spirit of the present invention.
