Abstract
The utility model provides a reusable filled-type fuse facilitating replacement of melt. The filled-type fuse comprises a ceramic sleeve pipe filled with quartz sand, as well as star-shaped ceramic skeletons winded with the melt. Both ends of the ceramic sleeve pipe are respectively welded with copper caps, end parts of the copper caps are provided with internal threads, the internal threads of the copper caps are connected with a bolt having outside threads, the bolt is upwardly opened with an allen wrench hole, and end parts of the melt are connected with the copper caps.
Description
Technical field
The utility model relates to a kind of fuse, relates in particular to a kind of filled type fuse that is convenient for changing melt.
Background technology
Fuse is the simplest protection electrical equipment, is used for protecting electric equipment to avoid transshipping and the infringement of short circuit current.The fuse that uses at present comprises porcelain bushing, the porcelain bushing two ends are sealedly connected with the copper cap by soldering, quartz sand is housed in the porcelain bushing, porcelain bushing is interior with ceramic skeleton, on the ceramic skeleton with melt, after the melt fusing, porcelain bushing and two ends copper cap integral body have just been scrapped, and have caused waste.
Summary of the invention
The purpose of this utility model provides a kind of reusable filled type fuse that is convenient for changing melt.
For achieving the above object, the technical solution adopted in the utility model is: a kind of filled type fuse that is convenient for changing melt, comprise porcelain bushing, quartz sand is housed in the porcelain bushing, the star ceramic skeleton also is housed in the porcelain bushing, be wound with melt on the star ceramic skeleton, it is characterized in that: the two ends of porcelain bushing are welded with respectively the copper cap, the end of copper cap is with internal thread, copper cap internal thread is connected with is with externally threaded bolt, bolt upwards has the allen wrench hole, and the end of described melt is connected with the copper cap.
This structure gathers, and the contact position of described copper cap and bolt is designed with sealing gasket.
The utility model has the advantages of and be: because this structure of the present utility model, after the fused mass of fuse fusing, can change inner melt by the sealed at both ends bolt of dismounting, porcelain bushing and two ends copper cap and inner ceramic skeleton repetitive cycling are used, save material.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In the accompanying drawing: 1, sealing gasket; 2, allen wrench hole; 3, bolt; 4, copper cap; 5, porcelain bushing.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
The utility model as shown in Figure 1, a kind of filled type fuse that is convenient for changing melt, comprise porcelain bushing 5, in the porcelain bushing 5 quartz sand is housed, the star ceramic skeleton also is housed in the porcelain bushing 5, be wound with melt on the star ceramic skeleton, it is characterized in that: the two ends of porcelain bushing 5 are welded with respectively copper cap 4, and the end of copper cap 4 is with internal thread, and copper cap 4 internal threads are connected with is with externally threaded bolt 3, bolt 3 upwards has allen wrench hole 2, and the end of described melt is connected with copper cap 4.In the present embodiment, described copper cap 4 is designed with sealing gasket 1 with the contact position of bolt 3.
Use the utility model: after fused mass of fuse fusing, the porcelain bushing bolts at two ends can be screwed off, pour out the quartz sand of filling, take out starlike ceramic skeleton, on starlike ceramic skeleton, again twine melt, it is inboard that its two ends are welded to the copper cap, screws an end sealing bolt, from the other end pack into fill quartz sand after the screwing hermetic bolt get final product.
