JPS5932976Y2 - Adhesive curing equipment for optical fiber connectors - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an adhesive curing device for fixing an optical fiber and an end member.

Conventionally, when manufacturing an optical fiber connector, the optical fiber and the terminal member are fixed using a bonding agent.

However, since the curing time of this adhesive is usually several hours or more, a heating method is used as a means of accelerating curing.

This is done using a heating device such as a thermostatic oven, but because the thermostatic oven is large, it has the disadvantage that it is difficult to transport when assembling optical fiber connectors at outdoor wiring sites or in station buildings. Even if it could be transported, it has the disadvantage that it is difficult to install it in narrow station buildings or outdoor wiring sites, especially in manholes.

SUMMARY OF THE INVENTION An object of the present invention is to provide an adhesive curing device for optical fiber connectors that eliminates the above-mentioned drawbacks.

Next, the present invention will be explained in detail with reference to the drawings.

FIGS. 1 and 2 are diagrams illustrating the manufacturing process of the optical fiber connector used in the present invention.

An optical fiber 2, which has been made bare by removing the tip covering material, etc., is inserted into the terminal member 1, and is filled with a fixing agent 3.

As the terminal member 1, a plug of an optical fiber connector or the like is used.

In addition, in FIG. 2, the adhesive 3 has not yet finished curing.

3 and 4 are a perspective view and a sectional view taken along the line A-A of the embodiment of the present invention, and FIG. 5 is an external view of the curing device according to the present invention.

In the figure, a heating holding section that holds and heats a plurality of terminal members 1 at the same time includes a heating device 4 and an upper lid 4', and a fiber holding section that holds a plurality of optical fibers 2 at the same time includes a fiber holder 7 and a fiber presser. plate 8.

The heating device 4 containing the heating element 5 and the temperature detector 6 is provided with a through hole 30 in which the terminal portion 1 is placed.

An upper lid 4 is attached to the upper part of the heating device 4 with a fixing fitting 10 for fixing the terminal member 1 and a pressing spring 11 for pushing down the fixing fitting 10.
' is placed.

Further, in order to prevent misalignment between the terminal member 1 and the optical fiber 2 or to prevent the fiber 2 from falling off, a fiber holder 7 and a fiber presser plate 8 are arranged at positions facing the heating device 4.

The heating device 4 and the fiber holder 7 are each mounted on a heat insulating material 9.

Furthermore, these components 4.4', 7 and 8 are housed in a storage box 12 having an opening/closing lid 13 provided with a hinge 14 at the top, forming one unit.

The optical fiber connector in the state shown in Figure 2 has a fiber holder 7.
They are arranged on the top of the fiber plate 8 and are held down by a fiber holding plate 8 having a rotation mechanism 17 and a locking mechanism 16 and a knob 15 on the other end.

In order to prevent the heating device 4 and the like from sticking to the heating device 4 due to the adhesive flowing out from the optical fiber connector, it is desirable that the heating device 4 and the upper lid 4' be coated with a non-adhesive resin.

Further, the heating element 5 and temperature detector 6 built into the heating device are connected to a known power source and temperature controller via lead wires 18 and 19, and desired heating is performed by these devices.

As described above, according to the present invention, it is possible to obtain adhesive curing performance equivalent to that of a conventional constant temperature bath, and since the local heating configuration of only the optical fiber connector is adopted, the device is extremely compact.
