Abstract
The utility model discloses a cartridge fuse, include: a body, end cap and fuse, the body be cavity form, install at the both ends of body the end cap, be provided with the fuse in the end cap is inside, the both ends of fuse contact with the end cap respectively, are provided with the filling layer in the inside of body, this filling layer is high silica sand or series thermal silica. The utility model discloses a ceramic body, designing in this internal fuse and designing in the end cap at body both ends, the fuse is installed in the body, and its both ends meet respectively with the end cap, and ceramic body can play fixed, blast proof effect, and when take place the short circuit or during through the heavy current, fuse fusing protects electrical apparatus, simple structure is efficient, has also reduced manufacturing cost.
Description
Technical field:
The utility model relates to fuse technical field.
Background technology:
Fuse, also known as fuse, fuse, is a kind of disposable elements be connected in order to protective circuit on circuit; when circuit power on flow through large time; make metal wire wherein or sheet produce high temperature and fuse, cause opening a way and interruptive current, avoid coming to harm with protective circuit.The fuse manually more renewed is needed to resume operation to make circuit after old blown fuse.During general electric equipment start energising, moment often has certain impulse current, and compared with normal operating current is high, and fuse will cause the puzzlement of use as fused immediately.
Electronic product is more and more tending towards miniaturized, and the size of termination and pad is also more and more less, thus also more and more higher to the welding requirements of small-sized original paper.Traditional fuse can not address this need.
In view of this, the present inventor proposes a kind of cartridge fuse.
Utility model content:
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of cartridge fuse.
In order to solve the problems of the technologies described above, the utility model have employed following technical proposals: a kind of cartridge fuse, comprising: a body, end cap and fuse; Described body is hollow form, and the two ends of body are provided with described end cap, and end cap interior is provided with fuse, and the two ends of fuse contact with end cap respectively, and the inside of body is provided with packed layer, and this packed layer is high silica sand or heat conductive silica gel.
Furthermore, in technique scheme, described body is ceramic body, and body is the rectangle of hollow, is provided with rectangle end cap in the two ends of body.
Furthermore, in technique scheme, its two ends of described body are wrapped in rectangle end cap.
Furthermore, in technique scheme, fixedly mount between described end cap and body.
Furthermore, in technique scheme, described fuse element length is greater than body length, and the two ends of fuse are stretched out originally external.
Furthermore, in technique scheme, described fuse two ends pass end cap.
Furthermore, in technique scheme, be welded and fixed between described kink and end cap.
Furthermore, in technique scheme, described end cap is metal material.
After adopting technique scheme; the utility model has following beneficial effect compared with prior art: the utility model comprises a ceramic body, design in intrinsic fuse and the end cap that designs in body two ends; fuse is installed in body; its two ends connect respectively with end cap; body interior is filled with high silica sand or heat conductive silica gel; fixing, explosion-proof effect can be played; when being short-circuited or by big current; fuse failure; protective device; structure is simple, and efficiency is high, also reduces production cost.
Accompanying drawing illustrates:
Fig. 1 is stereogram of the present utility model;
Fig. 2 is cutaway view of the present utility model.
Embodiment:
Below in conjunction with specific embodiments and the drawings, the utility model is further illustrated.
See shown in Fig. 1-2, a kind of cartridge fuse, comprising: a body 1, end cap 2 and fuse 3; Described body 1 is in hollow form, and the two ends of body 1 are provided with described end cap 2, and end cap 2 inside is provided with fuse 3, and the two ends of fuse 3 contact with end cap 2 respectively, and the inside of body 1 is provided with packed layer 4, and this packed layer 4 is high silica sand or heat conductive silica gel.
Specifically, described body 1 is ceramic body, the rectangle of body 1 in hollow, and be provided with rectangle end cap 2 in the two ends of body 1, its two ends of body 1 are wrapped in rectangle end cap 2, by encapsulating mutually between end cap 2 with body 1.
Described fuse 3 length is greater than body 1 length, and the two ends of fuse 3 are stretched out outside body 1, and fuse 3 two ends are stretched out outside end cap and between end cap 2 and are welded and fixed.
Described body adopts ceramic material, and end cap 2 is metal material, can be copper material.Fuse is installed in body, and its two ends connect respectively with end cap, is filled with high silica sand or heat conductive silica gel in ceramic body, can play fixing, explosion-proof effect; when being short-circuited or by big current, fuse failure, protective device; structure is simple, and efficiency is high, also reduces production cost.
Certainly, the foregoing is only specific embodiment of the utility model, be not limit the utility model practical range, all equivalences done according to structure, feature and principle described in the utility model claim change or modify, and all should be included in the utility model claim.
