Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of fuses, and particularly relates to a fuse holder with a pipe-to-plug type. BACKGROUND

[0002] The fuse holder is a commonly used circuit protection component for fixing a fuse. The cover and the fuse pipe square pipe or circular pipe of the existing fuse holder are generally not in a constraint relationship. When the fuse is replaced, the cover is removed, and then a tool is needed to take out the fuse pipe. The maintenance and replacement are inconvenient, and the efficiency needs to be improved. CONTENT OF THE UTILITY MODEL

[0003] Therefore, the application provides a fuse holder with a pipe-to-plug type to solve all or part of the technical problems described in the background art.

[0004] The innovative idea of the application is that the fuse pipe is fixed in the cover of the fuse holder, and the fixed connection between the base and the cover is realized through the plug-in cooperation relationship between the cover and the fuse holder. When the fuse is replaced, the cover is removed to take out the fuse pipe that needs to be replaced, which helps to improve the replacement efficiency.

[0005] To solve the technical problems, the application provides the following solutions:

[0006] A fuse holder with a pipe-to-plug type comprises a base and a plug-in part. The base is provided with a plug-in slot. The plug-in part is provided with a plug-in head, and the plug-in head is provided with a pipe hole. The pipe hole is provided with pipe clamps at both ends. The plug-in head is arranged in the plug-in slot.

[0007] As a preferred plug-in head, the plug-in head is provided with a plug-in inner cavity, and the pipe hole penetrates the plug-in inner cavity. Further, the plug-in inner cavity is provided with a resilient beam, and the resilient beam has a curvature that bends into the plug-in inner cavity.

[0008] As a preferred base, the plug-in slot is provided with two polar piece slots at both sides. The polar piece slot comprises a vertical clamping slot, a horizontal clamping slot, and a slot bottom outlet. Further, the horizontal clamping slot is provided with a pipe top structure.

[0009] As a preferred polar piece, the fuse holder with a pipe-to-plug type further comprises two polar pieces. The polar piece comprises a pipe clamping part, a horizontal part, and a pin part. The pipe clamping part and the pin part extend along a direction perpendicular to the horizontal part. Further, the pipe clamping part comprises a first clamping edge and a second clamping edge. The first clamping edge is provided with a first half ring, and the second clamping edge is provided with a second half ring. The first half ring and the second half ring are in a corresponding orientation. Further, a buffer groove is formed between the first clamping edge and the second clamping edge.

[0010] Beneficial technical effects:

[0011] When installing the fuse, the fuse tube is fixed in the plug-in connector through the tube hole and the tube clamp on the plug-in connector, and then the plug-in connector is assembled into the plug-in slot on the base. The sidewall part of the base corresponding to the tube clamp on the plug-in connector will form a squeezing force on the tube clamp, and the tube clamp deforms towards the plug-in cavity, thereby realizing the fastening connection between the plug-in connector, the base and the fuse tube. When replacing the fuse, the plug-in part is pulled up to remove the plug-in part and the fuse tube at the same time, and after replacing the fuse tube, the plug-in part is inserted to complete the replacement.

[0012] The technical solutions and technical effects of the present application are described in detail below in combination with the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF DRAWINGS

[0024] Please refer to Figs. 1 to 4 , the tube-to-plug type fuse holder disclosed in the present application comprises a base 1, a plug-in part 2 and two pole pieces 3. The pole pieces 3 are assembled on the base 1 and are used to form the positive and negative poles of the fuse holder; the plug-in part 2 is used to fix the fuse tube and insert the fuse tube together with the plug-in part 2 into the base 1.

[0025] The base 1 is provided with a plug-in slot 11, and two polar piece slots 12 are formed at both ends of the plug-in slot 11; the two polar piece slots 12 are respectively used for assembling corresponding polar pieces 3.

[0026] Each polar piece slot 12 comprises a vertical clamping slot 121, a horizontal clamping slot 122, and a slot bottom extension opening 123; a top tube structure 124 is arranged in the horizontal clamping slot 122.

[0027] The polar piece 3 comprises a clamping tube part 31, a horizontal part 32, and a pin part 33; the clamping tube part 31 and the pin part 33 extend in a direction perpendicular to the horizontal part 32.

[0028] The clamping tube part 31 is arranged in the vertical clamping slot 121, the horizontal part 32 is arranged in the horizontal clamping slot 122, and the pin part 33 extends out of the slot bottom extension opening 123 to form two pins of a fuse holder of the base 1.

[0029] The clamping tube part 31 comprises a first clamping edge 311 and a second clamping edge 312; a first half ring 313 is arranged on the first clamping edge 311, and a second half ring 314 is arranged on the second clamping edge 312; the first half ring 313 and the second half ring 314 are oppositely arranged to form a clamping tube opening. A buffer groove 315 is formed between the first clamping edge 311 and the second clamping edge 312.
