Abstract
The utility model relates to electronic circuit field, is a kind of miniature, high performance, multi-functional, novel fuse tube, and it, in small-sized electronic product application, substantially increases its safety and reliability.The utility model high-performance, multi-functional fuse tube, the two cap of single tube, size: length is 20mm-40mm; External diameter 5mm-6mm; Internal diameter 3mm; Pipe wall thickness 1mm, is made up of quartz glass tube, metal cap and fusible link, and metal cap is buckled in quartz ampoule two ends, and fuse is through the hole in the middle of interior cap, and two ends scolding tin welds, then the outer cap of fastening.The utility model high-performance, multi-functional fuse tube are a kind of high-performance, Multifucntional protective tube, fuse tube possess simultaneously big current by time not disjunction, short-circuit current by time rapid disjunction function, also when profile size constancy, different heavy current impact energy can be reached.
Description
Technical field
The utility model relates to electronic circuit field, is a kind of miniature, high performance, multi-functional, and novel fuse tube, it substantially increases its safety and reliability in the application of small-sized electronic product.
Background technology
Fuse is after exceeding setting certain hour according to electric current, makes Melt molten with the heat that himself produces, thus a kind of current protector that the principle that circuit is disconnected is made.Fuse is widely used in low-voltage distribution system and control system and power consumption equipment, as short circuit and overcurrent protection, is apply one of the most general protection device.
Fuse is a kind of overcurrent protection electrical equipment.Fuse is primarily of melt and fusion tube two parts and the outer composition such as filled.During use, be series at by fuse in protected circuit, when the electric current of protected circuit exceedes setting, and after certain hour, the heat fusing melt produced by melt self, makes circuit disconnect, plays the effect of protection.
The electrical equipment of deenergizing is divided using metallic conductor as melt.Be series in circuit, when transshipping or short circuit current passes through melt, heating self fuses by melt, thus plays a protective role to electric power system, various electrical equipment and household electrical appliance.Have inverse time lag characteristic, when overload current hour, fusing time is long; When overload current is large, fusing time is short.Therefore, within the scope of certain overload current, recover normal to electric current, fuse can not fuse, and can continue to use.
Summary of the invention
The utility model high-performance, multi-functional fuse tube, material consists of quartz glass tube, metal cap and fusible link, and fusible link is conductive metal material.
The utility model high-performance, multi-functional fuse tube, length 20mm-40mm, external diameter 5mm-6mm, internal diameter 3mm, wall thickness 1mm, the two cap of single tube, described fuse tube configuration comprises: outer cap (1), interior cap (2), fusible link (3), quartz ampoule (4), wherein, it is outside that described interior cap (2) is placed on described quartz ampoule (4) two ends, described fusible link (3) is through cap (2) in described quartz ampoule (4) two ends and weld coupled, and described outer cap (1) is tightly placed in cap in two ends (2) outside.
The feature of the utility model high-performance, multi-functional fuse tube is, ensures that fusible link is in quartz ampoule middle.
The utility model high-performance, multi-functional fuse tube are a kind of high-performance, Multifucntional protective tube, fuse tube possess simultaneously big current by time not disjunction, short-circuit current by time rapid disjunction function, also when profile size constancy, different heavy current impact energy can be reached.
Accompanying drawing explanation
Fig. 1 is the apparatus structure schematic diagram of high-performance, multi-functional fuse tube embodiment;
Cap in the outer cap 2---of identifier declaration: 1---
3---fusible link 4---quartz ampoule
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, simple introduction is done below by the accompanying drawing used required in embodiment, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Embodiment
The utility model embodiment provides short-circuit protection in a kind of circuit; for in various protector; surge protector inside can be arranged on; can lightning current by time rapid disjunction; avoid surge protector catching fire, safe and reliable, can construction cost be reduced; simplify working procedure, saving space to a great extent.
Described fuse tube comprises fusible link, quartz ampoule, interior cap and outer cap, and the outer cover of described fusible link has quartz ampoule, and the two ends of described quartz ampoule are connected with interior cap respectively, and affiliated interior cap is connected respectively with the outer cap held; The two ends of described fusible link are extended the two ends of described interior cap respectively and weld.
This specification is for system embodiment, and because it is substantially similar to embodiment of the method, so description is fairly simple, relevant part illustrates see the part of embodiment of the method.
Above-described the utility model way of example, does not form the restriction to the utility model protection range.Any amendment within spirit of the present utility model and principle, equivalently replace and improve, all should be included within protection range of the present utility model.
