Connection；Can be joined directly together, it is also possible to be indirectly connected to by intermediary.For the ordinary skill in the art,
Concrete meaning of the above-mentioned term in the utility model can as the case may be understood.
Sensitive-type overcurrent protector as Figure 1-Figure 4, including square shell 1, be symmetricly set in square shell 1
Two pins 2, temperature-sensing element 3, two symmetrically arranged movable contacts 4 being fixed on temperature-sensing element 3, it is fixed on pin 2 and with it is dynamic
Stationary contact 5 that contact 4 is correspondingly arranged, adjusting screw 6 and it is arranged on spring 7 between temperature-sensing element 3 and square shell 1；Pin 2
One end be fixed in square shell 1, the other end stretches out from square shell 1；The center of temperature-sensing element 3 has quincunx hole
32, adjusting screw 6 is passed through from the center of quincunx hole 32 and is screwed with square shell 1 afterwards；Spring 7 is set in adjusting screw
Outside 6.
Wherein, temperature-sensing element 3 is bimetal leaf, and bimetal leaf is damaged in order to avoid spring 7 is contacted with bimetal leaf, two
One pad 8 is set between person, referring to Fig. 3, adjusting screw 6 sequentially pass through from top to bottom after temperature-sensing element 3, pad 8 and spring 7 with
Square shell 1 is screwed, and spring 7 is enclosed within the outside of adjusting screw 6, in order to prevent adjusting screw 6 from connecting with the screw thread of square shell 1
Loosening is connect, it is be bonded with square shell 1 by fixing glue 9 in the end of adjusting screw 6.
