External power supply device for optical fiber fusion splicer

Abstract

The invention discloses an external power supply device for an optical fiber fusion splicer. The external power supply device comprises a battery casing, wherein a positive pole wire holder and a negative pole wire holder are arranged on the battery casing and electrically connected with an electric energy switching device through wires; and the electric energy switching device is arranged in the battery casing, a positive pole of the electric energy switching device is electrically connected with the positive pole wire holder, a negative pole of the electric energy switching device is electrically connected with the negative pole wire holder, and the electric energy switching device is electrically connected with a power supply adapter arranged outside the battery casing. The electric energy switching device is arranged in an original battery casing of the optical fiber fusion splicer, the externally-connected power supply adapter is used for providing work power for the electric energy switching device and indirectly providing work voltage for the optical fiber fusion splicer, and through function extension of the power supply adapter, input of various power supply types is realized, so that the field adaptability of the optical fiber fusion splicer is improved substantially, materials of the power supply are convenient to obtain, and the work efficiency is obviously improved due to the fact that the device is not restricted by power supply voltage.

Description

technical field [0001] The invention relates to a power supply device, in particular to an external power supply device for an optical fiber fusion splicer. Background technique [0002] The optical fiber fusion splicer in the prior art is equipped with two 12V Ni-MH battery packs and a set of AC adapter with charging function to form the self-contained power supply system of the optical fiber fusion splicer. When the optical fiber fusion splicer with its own power supply is in use There are a lot of limitations, mainly in the following points: [0003] ①The battery capacity is small, the charging time is long, and a large amount of welding work cannot be completed continuously. [0004] ②The service life of the battery is short. Generally, after three to five years of use, the battery capacity will be significantly reduced, and even battery swelling and liquid leakage will occur, which affects the normal use of the optical fiber fusion splicer. [0005] ③ There is no subs...

AI Technical Summary

Problems solved by technology

[0003] ① The battery capacity is small, the charging time is long, and a large amount of welding work cannot be completed continuously

[0004] ②The service life of the battery is short. Generally, after three to five years of use, the battery capacity will be significantly reduced, and even battery swelling and liquid leakage will occur, which will affect the normal use of the optical fiber fusion splicer.

[0005] ③ There is no substitute for the self-contained power supply system of the fiber optic fusion splicer. The purchase cost of the fiber optic fusion splicer is high. According to the current frequency of use, the battery needs to be replaced once a year. The investment is large, which is not conducive to saving battery resources.
