Embodiment
Embodiment 1:
As shown in Figure 3 and Figure 4, protection component of the present invention comprises ceramic cylinder 3, wire 4, the end cap 1 assembling ceramic cylinder 3 two ends and the scolding tin 2 be located in end cap 1 bottom interior wall.Utilize scolding tin 2 that the two ends of wire 4 are fixed on ceramic cylinder 3 two ends, and formed with end cap 1 and be electrically connected.
The ceramic cylinder 3 of protection component is square exterior cross-section, and the end cap 1 be installed on it also is square bottom surface.The madial wall of two end cap 1 is respectively provided with a pair inwardly protruded tongue 6, tongue 6 end cap 1 wherein two be symmetrical arranged on opposite.The cross section of tongue 6 is rectangle, and this tongue 6 is connected with bottom end cap 1, extends to end cap 1 edge, and length is 2/3rds of end cap 1 height, and the distance between relative two tongues 6 is less than ceramic cylinder 3 external diameter.
This tongue 6 is once formed when being end cap 1 punch formings, without the need to other processing.Distance between two tongues 6 is less than the external diameter of ceramic cylinder 3, and its projection formed forms certain extruding reinforcement effect to ceramic cylinder 3, and realize combining closely between end cap 1 and ceramic cylinder 3 outer wall, the end cap 1 on protection component can not peel off easily.
