Extend between 1164 inside.Fusible elements 1170 can be also along the upper surface 1114 of first end 1104 and the second end
1106 lower surface 1120 extends, and extends partially along the one or more in multiple outer surfaces 1110.Such as Figure 10 B institute
Show, fusible elements can be a corrugated or " (drop-in) of arbitrary shape " line, in the first weldering in center cavity 1109
Extend between material dome 1177 and the second solder dome 1179.In this embodiment, solder dome is preferably formed in order to obtain,
Groove 1112 and 1118 is the entrance of the air pressure from cooling chamber (not shown).More specifically, this fuse bodies
Design allows pressure to penetrate along upper surface 1114 and lower surface 1120, and partially along one in multiple outer surfaces 1110
It is a or multiple penetrate.With only compared with tool slotted tradition in two sides slots main body, this allows preferably to be formed the first solder dome
1177 and the second solder dome 1179.
When first end cover 1162 and/or second end cover 1164 are forced into the corresponding first end 1104 of hollow body 1100
When on the second end 1106, groove 1112 and 1118 can completely or partially be filled with solder 1160.In some embodiments
In, first end cover 1162 and second end cover 1164 can be applied heat to, so that solder 1160 can flow.Therefore, groove
Bag portion of the one or more as solder 1160 in 1112 and 1118, and then help to maintain first end cover 1162 and second end
Lid 1164 and fusible elements 1170.More specifically, in some embodiments, the solder of the hardening in groove 1112 and 1118
1160 can with the coupling solder of the hardening in center cavity 1109 and end cap 1162,1164 or be integrally formed.As a result, groove 1112
With 1118 in hardening anchoring piece of the solder 1160 as pressing first end cover 1162 on it and second end cover 1164, the
One end cap 1162 and second end cover 1164 are applied to the fusible elements 1170 around first end 1104 and the second end 1106 again
Plus-pressure.
Although being not shown, hollow body 1100 can be on one in first end 1104 and the second end 1106
Or more on include metalization layer similar to metalization layer 908 shown in fig. 7.When first end cover 1162 or second end cover
1164 when being forced on each end 1104,1106, and solder 1160 can be contacted with metalization layer.Therefore, because metalization layer
It is in contact with the part of solder 1160 and fusible elements 1170, so that metalization layer can be in solder 1160, fusible elements
1170 and the first end cover 1162 and second end cover that are pressed on one or more of first end 1104 and the second end 1106
Promote to form steady electric conductivity between 1164.
Although describing hollow body fuse by reference to some embodiments and for manufacturing hollow body in structure
The method of fuse, it will be appreciated, however, by one skilled in the art that various changes can be carried out and can be replaced with equivalent
The spirit and scope changed without departing from claims hereof.Other can be carried out to modify so that specific condition or material adapt to
The scope of the claims is not being departed from introduction disclosed above.Therefore, claim should not be construed as limited to disclosed
Any one specific embodiment, but be construed as limited to fall into any embodiment of scope of the claims.
