Detailed Description

It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the disclosure. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.

As shown in fig. 1 to 4, a fuse safety protection structure includes a base 100 mounted with a fuse body 200, four partition plates 300 distributed at equal intervals are arranged on the front side of the base 100, and the fuse body 200 is mounted between two adjacent partition plates; still be equipped with the C type housing 400 of cover on the fuse body between two adjacent baffles, every fuse body both sides all are equipped with the baffle, a baffle of sharing between two adjacent fuses utilizes C type housing 400 to protect the fuse body simultaneously to improve the security of installation and use, avoid the interact between the fuse simultaneously.

In this embodiment, the upper and lower ends of the partition 300 are respectively provided with extending arms 310 extending backwards, the front side of the base is provided with a slot 110 engaged with the rear side edge of the partition, the upper and lower sides of the base are provided with sliding slots 120 for the extending arms to be slidably inserted, the rear end of the extending arm is provided with a hook 311, and the sliding slots on the upper and lower sides of the base are provided with protrusions 121 engaged with the hook; the installation of baffle need not to adopt the screw, directly adopt the mode of cartridge can, outwards break off the extension arm with the fingers and thumb during the dismantlement and make hook portion and lug break away from and can accomplish the dismantlement fast, easy dismounting.

In this embodiment, the side surface of the partition board is provided with guide grooves for the side edges of the two end plates of the C-shaped cover shell to be inserted in a sliding manner, and each guide groove is formed between the two limit bars 320; the C-shaped housing is not required to be connected by screws, and is directly limited by two adjacent partition plates and can be inserted into the C-shaped housing along the side edges of the end plates in a sliding manner along the guide grooves.
