Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
It please refers to Fig.1 and Fig. 2, the utility model provides a kind of plug with fusible link, including inner casing 1 and be arranged on inner casing
The first conducting wire 21, the second conducting wire 22, the second pin 31, the second pin 32 in 1, set fluted 11 on the inner casing 1, described
It is disposed with from inside to outside in groove 11 and turns shape connection sheet 8, fusible link 4 and annular connection 5；Specifically, described turn shape company
Contact pin 8 is L-shaped, and one side is located at the bottom of groove 11, and opposite side is extended to outside groove 11, and first conducting wire 21 and first is inserted
Foot 31 connects, and second conducting wire 22 is connected with turning the one side that shape connection sheet 8 is extended to outside groove 11, second pin 32 with
Annular connection sheet 5 connects, specifically, the side of the annular connection sheet 5 is provided with extension and is connected with the second pin 32；It is described
Cover 6 and the spring 41 for compressing fusible link 4 are provided in annular connection sheet 5；The second conducting wire 22 for setting gradually turns shape
Connection sheet 8, fusible link 4, spring 41, cover 6, annular connection sheet 5, the second pin 32 are electrically connected, be worth mentioning when, cover
6 parts contacted with annular connection sheet 5 are supported using conductive material, and are adopted and be made from an insulative material at the top of cover.According to electricity
Device selects the fusible link of corresponding specification, and when the electric appliance overburden for flowing through the plug is run, fusible link disconnects, and cuts off the confession of electric appliance
Electric line avoids further damage, while does not influence the running of other electric appliances again.
In this present embodiment, annular 5 inner wall of connection sheet is provided with internal thread, and 6 side of cover is provided with and institute
State the matched external screw thread of internal thread.When needing replacing the fusible link 4 inside it, cover 6 only need to be unscrewed, by spring 41 and damage
Bad fusible link 4 takes out, the fusible link 45 that juxtaposition renews, and the effect of spring 41 is to compress fusible link 4 and is allowed in turning shape
