Embodiment 1

[0030] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, the optical fiber access structure of the explosion-proof fusion splicer in this embodiment includes an upper shell 5 and a lower shell 2 that are fastened together, and an explosion-proof groove 3 is provided on the explosion-proof surface 4 of the lower shell 2 . The explosion-proof groove 3 is a rectangular or V-shaped groove processed on the explosion-proof surface 4 under the premise that the pressure of the explosion-proof casing is allowed. Compress to seal.

[0031] When using, the operation steps are as follows:

[0032] 1. Put the optical fiber 1 into the explosion-proof groove 3, making sure it is flat and free of warping.

[0033] 2. Press the upper cover 5 of the explosion-proof fusion splicer under the cover, and perform the fusion splicing and heat shrinking operation of the optical fiber 1.

[0034] The processing method of the explosion-proof groove illustrated in this structure is a ...

Embodiment 2

[0041] This embodiment is an improvement on the basis of Embodiment 1, as Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, two parallel explosion-proof grooves 3 are provided on the explosion-proof surface 4 of the lower shell 2, and two optical fibers 1 can be put in at the same time after the upper shell 5 is opened once; Fusion can also be performed on one optical fiber, and one optical fiber can be thermally fused. The opening and closing times of the explosion-proof shell are reduced, and the work efficiency is further improved.

Abstract

The invention discloses a fiber accessing structure of an explosion-proof welding machine. A fiber can be rapidly and effectively accessed to the explosion-proof welding machine in an explosive gas and dusty environment. The fiber accessing structure comprises an enclosed explosion-proof housing which has an openable explosion-proof surface, and an explosion-proof groove for receiving a fiber is formed in the explosion-proof surface. The size and the weight of the machine are reduced, accessing and placing of a fiber is facilitated, and the operation performance of the explosion-proof welding machine is improved. The accessing problems of accessing a fiber to the explosion-proof welding machine are solved, the operation method is simplified, and use efficiency is improved.

Description

technical field [0001] The invention relates to a component of an optical fiber fusion splicer, in particular to an optical fiber access structure of an explosion-proof fusion splicer. Background technique [0002] With the continuous development of optical fiber communication, optical fiber has been widely used in underground coal mines and other environments containing explosive gas and dust. However, due to the harsh environment of coal mines, there are often faults that the optical cable is damaged, and it needs to be repaired in time. [0003] Explosion-proof fusion splicers developed in the market have complex connection forms, difficult operation and high cost. Contents of the invention [0004] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides an optical fiber access structure capable of fast optical fiber fusion splicing and heat shrinkable sleeve heating in an environment where flammable and explosiv...
