According to the utility model, due to the screw structure, the screw is not required to be in contact with the internal structure of the fuse link when being disassembled, so that leakage of arc extinguishing sand is avoided, and adverse phenomena such as bouncing of an indicator are avoided.
Description
Technical Field
The utility model relates to the field of power and communication, in particular to a fuse link structure with an installation indicating fuse.
Background
The fuse link structure with the indicating fuse indicates whether the fuse link works through the indicating fuse. The indicating fuse is generally arranged outside the fuse link structure, and the indicating work is performed through the indicating copper wire fuse. There are various ways of fixing the indicating fuse at the periphery of the fuse link structure. For example, chinese patent CN201420191897.6 discloses a fuse, when the indicating fuse is mounted outside the fuse link structure, a set of screws at two ends of the fuse link structure need to be removed first, and then the indicating fuse is fixed outside the fuse link structure by the screws. However, in the process of removing the screw, the phenomena of sand leakage, bouncing of the indicator and the like are often caused, and the product is scrapped.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a fuse link structure for installing an indicating fuse, and by means of a special screw structure, when a screw is dismantled, the screw cannot touch the internal structure of the fuse link, so that adverse phenomena such as sand leakage or bouncing of an indicator are avoided, and the product yield is improved.
In order to solve the technical problems, the technical scheme provided by the utility model is that the fuse link structure for installing the indicating fuse comprises a fuse link shell and cover plates positioned at two ends of the shell, wherein the indicating fuse is installed on the fuse link structure through a screw structure; the screw structure comprises an outer screw and an inner screw which are in threaded connection; the cover plate is fixed on the fuse body shell by the outer screw; the connecting end of the indicating fuse link is positioned between the inner screw and the outer screw.
Preferably, the outer screw extends outwards to form a pressing part near the outer circumference of one end of the inner screw, and the pressing part of the outer screw fixes the cover plate on the end face of the fuse body shell.
Preferably, the inner screw and the outer screw are coaxially arranged.
Preferably, at least one group of screw structures are respectively arranged at two ends of the fuse body shell.
According to the utility model, the cover plate is fixed on the fuse link shell through the outer screw of the screw structure, and when the screw is dismounted, only the inner screw is required to be unscrewed, and the cover plate is not required to be contacted with the internal structure of the fuse link, so that the leakage of arc extinguishing sand is avoided, and the adverse phenomena such as bouncing of the indicator are avoided.

Detailed Description
The utility model relates to a fuse link structure for installing an indicating fuse, which comprises an outer screw and an inner screw which are in threaded connection; the connection end of the indicating fuse is located between the inner screw and the outer screw.
Referring to fig. 1, the fuse 1 is indicated to be mounted on the outside of the fuse link 2. The fuse-link 2 comprises a housing 3 and cover plates 4 positioned at two ends of the housing 3, wherein the cover plates 4 are fixedly arranged on the housing 3 through common screws 5 and screw structures 6. The connecting end of the indicating fuse 1 is fixed to the cover plate 4 of the fuse link 2 by a screw structure 6.
Referring to fig. 2, the screw structure 6 comprises an outer screw 7 and an inner screw 8. The end face of one end of the external screw 7 is provided with a threaded hole 71, the outer periphery of the end provided with the threaded hole 71 extends outwards to form a pressing part 72, and external threads are arranged on the outer periphery of the external screw 7. The internal screw 8 is screwed into the screw hole 71. The inner screw 8 extends outward from an outer periphery of one end of the screw hole 71 to form a pressing portion 81. For better fixing effect, the outer screw 7 and the inner screw 8 are coaxially arranged.
Referring to fig. 3, a mounting hole is formed in the end face of the wall of the housing 3, the cover plate 4 is located at the end face of the housing 3, and the external screw 7 is mounted on the mounting hole of the housing 3 to press the cover plate 4 against the end face of the housing 3. The connecting end 11 of the indicating fuse 1 is placed on the outer end face of the pressing part 72 of the outer screw 7, the inner screw 8 passes through the connecting end 11 of the indicating fuse 1 and then is connected with the threaded hole 71 of the outer screw, and the connecting end 11 of the indicating fuse 1 is fixed between the pressing parts of the outer screw 7 and the inner screw 8.
According to the screw structure, when the fuse link 2 is assembled, the cover plate is fixed on the fuse link shell by at least adopting the cooperation of the external screw of a group of screw structures and the common screw. When the indicating fuse 1 is installed, the connecting end of the indicating fuse is directly fixed on the outer screw through the inner screw. The outer screw is not required to be removed, so that adverse phenomena such as sand leakage and indicator bouncing are not caused.
