Detailed description of the invention:
Embodiment: as shown in Fig. 1 is to 5, the thermel protection device of a kind of mobile communication equipment lithium battery,
Including shell 1, upper cover 3 and the battery core body 2 of rectangle, in battery core body 2 is plugged on shell 1 and become
Type has two cylindrical electrode tip holders 21, and electrode tip holder 21 exposes the upper surface of upper cover 3, shell 1
Upper end is fixedly connected with case 4, and case 4 forms two cylindrical sockets 41, conductive pole 5
Upper end be plugged in the socket 41 of case 4, lower end is plugged in the electrode tip holder 21 of battery core body 2,
The two ends of connecting rod 6 are separately fixed on conductive pole 5, molding on case 4 top end face of connecting rod 6 both sides
Having louvre 42, be plugged with cap 8 in louvre 42, the lower end of cap 8 forms stud 81,
Stud 81 is screwed onto on meltable nut 10, and meltable nut 10 is fixed on upper cover 3, described stud
81 upper sleeves have stage clip 9, the two ends of stage clip 9 to press up against on cap 8 and upper cover 3, described
