Embodiment
Referring to figs. 1 through Figure 10, the utility model thermal element Assemblies Example is described further.
A kind of thermal element assembly, comprise thermal element body 2, described thermal element body 2 comprises fixture 22 and movable part 21, and fixture 22 is hinged with movable part 21, and movable part 21 is connected with bimetal leaf 1 slippage.When the load, thermal element body 2 generates heat, and then passes to bimetal leaf 1, bimetal leaf 1 heated bending, and drive time delay nail 3 to promote bracket 4 and rotate, bracket 4 is passed to operating mechanism power thus realized dropout process.Such scheme is when transshipping, and bimetal leaf 1 bends, and movable part 21, due to hinged with fixture 22, is rotated around hinged place by the drive of bimetal leaf 1, and movable part 21 is abutted with bimetal leaf 1 all the time.Thus ensure that the contact area of thermal element assembly and bimetal leaf 1, thus ensure the sensitivity of circuit breaker.Movable part 21 is provided with chute 211, and chute 211, along bimetal leaf 1 length direction, bimetal leaf 1 is connected with slide block 11, and slide block 11 is connected with chute 211 slippage.Chute 211 comprises location notch 2112 and slippage slot 2111, location notch 2112 is communicated with slippage slot 2111, slide block 11 comprises locating piece 112 and slipping block 111, slipping block 111 is affixed with bimetal leaf 1, locating piece 112 and slipping block 111 are wholely set, locating piece 112 is positioned at location notch 2112, because the thermal coefficient of expansion difference of two panels sheet metal because bimetal leaf 1 is bending, it is bending that bimetal leaf 1 expanded by heating can make bimetal leaf 1 extend, movable slider 11 can be with to move, movable part 21 is driven to fit bimetal leaf 1 while this scheme slide block 11 just can slide in chute 211, ensure the contact area of thermal element assembly and bimetal leaf 1.
Be provided with groove as another optimal technical scheme slide block 11 both sides, in chute 211, be provided with the raised line with groove fit, while this scheme can make slide block 11 slide in chute 211 equally, drive movable part 21 to fit bimetal leaf 1.Can also chute 211 be dovetail groove, slide block 11 be trapezoid block.
