Abstract
The utility model discloses a novel fuse, which comprises an H-type PCB (printed circuit board) made up of a first vertical board, a second vertical board, and a horizontal board, and a first terminal and a second terminal for being electrically connected with the circuit. The H-type PCB comprises a base board and copper foil coating the surface of the base board; the shape of the copper coil is matched with the base board; the first vertical board is connected with the first terminal; and the second vertical board is connected with the second terminal. The novel fuse has the first significant beneficial effects that mounting and maintenance are facilitated, the outer insulating sheath and the inner terminal of the H-type PCB of the fuse are both provided with buckles, and when the PCB is melted, disassembly and replacement by a maintainer is facilitated. While, both ends of the existing fuse are outgoing leads and can only in welding connection with the circuit rather than in connection with terminals with buckles, plastic sealing is carried out on the shell in a plastic injection mode, and when the fuse is melted, the entire outer circuit of the fuse needs to be removed, and disassembly and replacement are extremely inconvenient; the second beneficial effects that the shape is delicate and the application is wide; and the third beneficial effect that the production cost is reduced.
Description
Technical field
The utility model relates to a kind of fuse.
Background technology
There is the use fuse link in a lot of places in electron trade, and fuse link is that the yellow gold that fusing point is lower by resistivity is larger is made mostly at present.Have following problems: blown fuse device manufacturing process is complicated, cost is high, just can't use in a large number in the situation that fusing time is less demanding, cost requirement is low, only need to protect the large current phenomena of circuit in some circuit, and in the situation that requires to reduce costs, present blown fuse device is also inapplicable; The blown fuse device adds in the injection moulding situation outside, and whole volume is all larger, and less situation more can't be used the welding of blown fuse device and circuit connecting wire in the space, in case will be difficult to change inconvenient installation and maintenance after fusing.
The utility model content
The utility model proposes a kind of new type fuse for above-mentioned ubiquitous problem.
The design that the utility model is taked is:
A kind of new type fuse comprises the H type pcb board that is made of starting stave, the second riser, transverse slat, is used for the first terminal, the second terminal that are electrically connected to circuit; Described H type pcb board comprises substrate, covers the Copper Foil of substrate surface, and shape and the substrate of Copper Foil adapt, and starting stave connects the first terminal, and the second riser connects the second terminal.
Preferably, described the first terminal, the second terminal H type fixed by snap pcb board.
Preferably, also comprise the insulation protective jacket that covers H type pcb board, described insulation protective jacket is fixed by snap on H type pcb board.
In sum, the utlity model has following significant beneficial effect:
(1) facilitate installation and maintenance, the insulating sleeve of the H type pcb board outside of fuse and inner terminal, are convenient to maintenance personal's dismounting and change after pcb board fusing all with buckle.And the fuse two ends that have now are the wires of drawing, and can't be connected with the terminal with buckle, can only weld with circuit, and shell carries out plastic packaging with the mode of injection moulding, after blown fuse, and the whole fuse external circuit of need to dismantling, very inconvenient dismounting, replacing; (2) shape is small and exquisite, widely applicable, and the application's fuse mainly is comprised of a fritter pcb board, there is no outer glass or the ceramic packaging of general insurance silk, in the situation that anti-same current size, the volume of pcb board fuse is again little many; (3) reduced production cost, fuse mainly is comprised of a fritter pcb board, produces simply, and simple for structure, production cost is low, is easy to large-scale production.
Description of drawings
Accompanying drawing 1 is the described H type of a kind of new type fuse described in the utility model pcb board structural representation.
Embodiment
In order to allow those skilled in the art understand better the technical solution of the utility model, below in conjunction with accompanying drawing, the utility model is further elaborated.
As shown in Figure 1, a kind of new type fuse comprises the H type pcb board that is made of starting stave 1, the second riser 2, transverse slat 3, is used for the first terminal, the second terminal that are electrically connected to circuit; Described H type pcb board comprises substrate, covers the Copper Foil of substrate surface, and shape and the substrate of Copper Foil adapt, and starting stave 1 connects the first terminal, and the second riser 2 connects the second terminal.Described the first terminal, the second terminal H type fixed by snap pcb board.Also comprise the insulation protective jacket that covers H type pcb board, described insulation protective jacket is fixed by snap on H type pcb board.
The surface coverage Copper Foil of described substrate refers to that a surface of substrate all covers Copper Foil, and generally the thickness of Copper Foil is identical, and the thickness that certainly horizontal version is located can erect version from first, the second perpendicular version is different.Horizontal version in described H type pcb board is namely the fuse-link in fuse.When electric current was excessive, this very narrow Copper Foil resistance was larger, and temperature raises very fast, and reaching certain value is the fusible Copper Foil.
The PCB fuse link is comprised of H type pcb board, terminal, insulating sleeve.Pcb board is comprised of a rectangle pcb board that is paved with Copper Foil, and is cut in the middle of the rectangle pcb board, only stays a very narrow Copper Foil, is namely the horizontal version of H type pcb board.The thickness of the Copper Foil in horizontal version and the size that width has determined blowout current, therefore the thickness of the just middle very narrow one section Copper Foil of the difference of pcb board fuse link blowout current size is different with width, so the shape of horizontal version can be set according to actual needs.The pcb board two ends are connected with two terminals with buckle, the outside be one with the insulation protective jacket of buckle, facilitate the replacing of H type pcb board.The pcb board two ends are to be connected with a kind of terminal with buckle, and after pcb board fusing, only need extract pcb board changes new getting final product again.The casing insulation sheath is also with buckle, removable Reusability.
When the electric current of circuit was excessive, because the Copper Foil in PCB stage casing is very narrow, resistance was larger, and temperature raises rapidly, when reaching certain value, Copper Foil is fused, and open circuit, thus play the purpose of the whole circuit of protection.After the fusing of pcb board Copper Foil, the maintenance personal only need open casing insulation sheath buckle, extracts pcb board, changes new installing and gets final product.This pcb board fuse will be more a lot of than the volume-diminished of blown fuse device, and it is convenient in the situation that the space is less uses.
Need to prove; in the situation that do not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these changes and distortion all should belong to the protection range of the appended claim of the utility model.
