Specific implementation mode
Preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.
Embodiment 1：
As shown in Figure 1, a kind of switching device in the case of high overload, includes mainly screw plug 1, outer housing 2, stick harness
3, plastic tube 4；
Screw plug 1 is the cylindrical structure that hard material is process, and periphery is provided with the screw thread for being connect with outer housing, interior
Hole is stepped hole, and end orifices are used for maintenance extracting power supply cord, and internal macropore is used to place rich power cord；
The outer housing 2 as shown in Fig. 2 (a), (b) is the cylindrical structure that hard material is process, and endoporus is stepped hole, upper end
Macropore inner wall is provided with screw thread for being connect with screw plug, and size matches with screw plug outside diameter, and square hole is arranged below in macropore
For being caught in stick harness upper end square-section, lower end is the through-hole for installing plastic tube, and there are the apertures of cabling for bottom；
As shown in figure 3, stick harness 3 is the nail shape structure that hard material is process, upper end is square-section, prevents stick harness from existing
Relative rotary motion is generated in the case of high-speed motion with outer housing, conducting wire winding twists off problem；Lower end fades to taper by cylinder,
It being equipped with annular convex platform on cylinder and the conical surface --- annular convex platform I 9 and annular convex platform II 12, there are the through-hole of cabling, bottoms at center
Portion is the position for installing plug；
As shown in figure 4, plastic tube 4 is nonmetallic for that can deform upon, there are good intensity, endoporus bottom to taper into,
And upper end, which is equipped with two circles, can generate protruding point --- hemisphere salient point I 10 and the hemisphere salient point II 11 of resistance, be set in the present embodiment
It sets and is uniformly distributed eight protruding points on same circumference, it is the position for installing socket that, which there are a circle groove 13, bottom in lower end,.
