Abstract
The utility model discloses a avoid emitting novel porcelain tube structure of tin, including porcelain tube body, fuse and copper cap, the fuse is buried in the porcelain tube originally internally, and porcelain tube body both ends cover is equipped with the copper cap, is equipped with the tin silk in the copper cap, and the fuse both ends are in the same place with the soldering of copper cap, the quartz sand is equipped with in the porcelain tube body, porcelain tube body both ends have been seted up and have been avoided emitting the tin structure, avoid emitting the tin structure and be located the copper cap. In this way, the utility model discloses simple structure, design benefit, that in time discharge welding and the disconnected heat and the gas that produce in the testing process of dividing avoid emitting tin.
Description
Technical Field
The utility model relates to a fuse-link technical field especially relates to a avoid emitting novel porcelain tube structure of tin.
Background
The existing fuse link is assembled as follows: the fuse wire is welded together with a copper cap, the fuse wire passes through the porcelain tube, the copper cap is sleeved at one end of the porcelain tube, the copper cap is sleeved at the other end of the porcelain tube, a tin wire is arranged in the copper cap, the copper cap heats the tin wire to melt and welds the fuse wire onto the copper cap, the end face of the porcelain tube is a complete plane at present, in order to ensure that the fuse wire and the copper cap are welded in place, the end face of the porcelain tube is tightly attached to the copper cap, the condition of tin leakage is easy to occur when the copper cap at the second end is welded, the tin leakage has influence on the fusing characteristic of a product, the resistance of the product is possibly abnormal, the appearance is not attractive, in the welding process, the heat in the porcelain tube is difficult to discharge, in addition, when a fuse link is subjected to a breaking test, the fuse wire can generate certain heat and gas, and the product quality is influenced.
Based on the above defects, it is necessary to improve the prior art and design a new porcelain tube structure to avoid the occurrence of tin.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the main technical problem who solves provides a avoid emitting novel porcelain tube structure of tin, simple structure, design benefit, and that welds and divides heat and the gas that produces among the disconnected testing process of the branch in time discharge avoids emitting tin.
In order to solve the technical problem, the utility model discloses a technical scheme be: the utility model provides a avoid emitting novel ceramic tube structure of tin, this kind of avoid emitting novel ceramic tube structure of tin includes ceramic tube body, fuse and copper cap, the fuse is buried in the ceramic tube originally internally, and ceramic tube body both ends cover is equipped with the copper cap, is equipped with the tin silk in the copper cap, and the fuse both ends are in the same place with the copper cap tin soldering, the quartz sand is equipped with in the ceramic tube body, ceramic tube body both ends have been seted up and have been avoided emitting the tin structure, it is located the copper cap to avoid emitting the tin structure.
Preferably, the tin leakage preventing structure is an arc-shaped opening, and at least two arc-shaped openings are formed at two ends of the porcelain tube body.
Preferably, the tin-covering-preventing structure is a round hole, the round holes are formed in two sides of the porcelain tube body 1, and the round holes are through holes.
Preferably, the porcelain tube body and the copper cap are in clearance fit.
Compared with the prior art, the beneficial effects of the utility model are that:
simple structure, design benefit, that in time discharge welding and breaking apart heat and the gas that produces among the test process, avoid letting out tin.

Detailed Description
The following detailed description of the preferred embodiments of the present invention will be provided to enable those skilled in the art to more easily understand the advantages and features of the present invention, and to make clear and definite definitions of the protection scope of the present invention.
Referring to fig. 1 to 4, an embodiment of the present invention includes:
the utility model provides a avoid emitting novel ceramic tube structure of tin, this kind of avoid emitting novel ceramic tube structure of tin includes ceramic tube body 1, fuse 2 and copper cap 3, fuse 2 buries in ceramic tube body 1, and 1 both ends cover of ceramic tube body is equipped with copper cap 3, is equipped with tin silk 4 in the copper cap 3, and 2 both ends of fuse are in the same place with 3 tin weldings of copper cap, the quartz sand 5 is equipped with in the ceramic tube body 1, 1 both ends of ceramic tube body have been seted up and have been avoided emitting tin structure 10, it is located copper cap 3 to avoid emitting tin structure 10.
The anti-tin-overflowing structure 10 is an arc-shaped opening 101, and at least two arc-shaped openings 101 are formed in two ends of the porcelain tube body 1.
The anti-tin-overflowing structure is a round hole 102, the round holes 102 are formed in two sides of the porcelain tube body 1, and the round holes 102 are through holes.
The porcelain tube body 1 and the copper cap 3 are in clearance fit.
The utility model relates to a when avoiding emitting novel porcelain tube structure assembly of tin, fuse 2 welds in the copper cap 3 of one side earlier, this 3 suits of copper cap are to porcelain tube body 1, fuse 2 passes porcelain tube body 1, 1 inner tank of porcelain tube body is equipped with quartz sand 5, 3 suits of another copper cap are to 1 opposite side of porcelain tube body, heat copper cap 3, the tin silk melts in the copper cap 3, fuse 2 welds on copper cap 3, in the heat-welding process, the heat is got rid of through avoiding emitting tin structure 10 in the welding process, avoid emitting tin, in addition, avoid emitting tin structure 10 also has certain benefit to dividing the test, do benefit to heat and gas that the branch produced among the branch test procedure of discharging, enable the product to bear higher branch and divide.
The utility model relates to a avoid emitting novel porcelain tube structure of tin, simple structure, design benefit, that in time discharge welding and the heat and the gas that produce in the disconnected testing process of branch avoid emitting tin.
The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
