Summary of the invention
This utility model aims to solve the problem that existing mounting means exists to be difficult to debug, the temperature sensor test point detection problem such as inaccurate and the mounting structure of a kind of breaker temperature sensor is proposed, sensor adopts bayonet-like structures to fix, it is simple to snap in the Flos Nelumbinis limb on lotus contact and convenient disassembly.Sensor base and Flos Nelumbinis limb are in close contact after snapping in, and directly can accurately measure the temperature of this location point.
For achieving the above object, this utility model takes techniques below scheme: the mounting structure of a kind of breaker temperature sensor, including the lotus contact on chopper and the Flos Nelumbinis limb on lotus contact, it is characterised in that:
Also including temperature sensor, described temperature sensor includes PCBA board, heat-conducting block and base；PCBA board and heat-conducting block are welded and fixed；Heat-conducting block is fixed on base；
The base of described temperature sensor is buckled on Flos Nelumbinis limb, detects temperature by heat-conducting block.
More specifically, described base includes bedplate, along the bent shell fragment of the long spring of bedplate and be the buckle of 90 ° of angular distortions along bedplate minor face, the end of buckle is provided with snap fit.
More specifically, described PCBA board is welded by print solder with heat-conducting block.
More specifically, described PCBA board is protected by injection moulding sealing away from the side of heat-conducting block.
More specifically, the material that described heat-conducting block adopts is metallic copper material.
This utility model is owing to taking above technical scheme, and it has the advantage that
1, this utility model arranges base in temperature sensor, is arranged on Flos Nelumbinis limb by base snap, and installation and removal are convenient；Heat-conducting block close contact Flos Nelumbinis limb in temperature sensor, detects the temperature at Flos Nelumbinis limb place directly and accurately.
2, the base of temperature sensor arranges shell fragment and snap fit, catches on Flos Nelumbinis limb by snap fit, and shell fragment compresses Flos Nelumbinis limb simultaneously so that temperature sensor is installed stronger on Flos Nelumbinis limb.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of temperature sensor.
Fig. 3 is that the temperature sensor in Fig. 2 turns clockwise the schematic diagram after 45 degree in the horizontal plane.
Detailed description of the invention
In order to make the purpose of this utility model embodiment, technical scheme and advantage clearly, below in conjunction with drawings and Examples, this utility model is described in detail.
As shown in Figure 1 to Figure 3, the mounting structure of a kind of breaker temperature sensor that the utility model proposes, including the lotus contact 1 on chopper, the Flos Nelumbinis limb 2 on lotus contact 1 and temperature sensor 3.Wherein, temperature sensor 3 is a kind of brand-new structure, is arranged on chopper lotus contact 1, and sensor adopts bayonet-like structures to fix, it is possible to easily snap in Flos Nelumbinis limb 2 and convenient disassembly.
Temperature sensor 3 includes PCBA board 31, heat-conducting block 32 and base 33.PCBA board 31 and heat-conducting block 32 are welded and fixed, and welding manner adopts print solder welding, and PCBA board 31 is weldingly fixed on the side of heat-conducting block 32, and PCBA board 31 then protects, away from the side of heat-conducting block 32, PCBA board 31 part exposed by injection moulding sealing 34.
Heat-conducting block 32 is fixed on base 33, base 33 includes bedplate 331, along the bent shell fragment 332 of the long spring of bedplate 331 and be the buckle 333 of 90 ° of angular distortions along bedplate 331 minor face, the angle that shell fragment 332 and bedplate 331 are formed is less than 90 ° of angles, and the end of buckle 333 is provided with snap fit.Heat-conducting block 32 is arranged on the long limit of bedplate 331, is positioned at the face that shell fragment 332 is relative, is screwed.Heat-conducting block 32, bedplate 331 and shell fragment 332 form "U" shaped structure.When temperature sensor 3 is installed on-board the circuit breaker, the "U" shaped structural openings place that the heat-conducting block 32 of temperature sensor 3 and base 33 are formed snaps in the Flos Nelumbinis limb 2 on lotus contact 1, snap fit on buckle 333 catches on the bottom of Flos Nelumbinis limb 2, simultaneously, shell fragment 332 is pressed on Flos Nelumbinis limb 2, prevent temperature sensor 3 from dropping so that temperature sensor 3 is fixed on lotus contact 1.
Wherein, the base 33 of this enforcement example is formed by stainless steel material bending, the shell fragment 332 that rustless steel is made, and ductility is good, it is not easy to abrasion.The material that heat-conducting block 32 adopts is metallic copper material, copper there is good heat conductivity and electric conductivity, it is heat-conducting block 32 that temperature sensor 3 snaps in the wherein one side structure of the "U" shaped structure in Flos Nelumbinis limb 2, heat-conducting block 32 directly contacts Flos Nelumbinis limb 2, and compressed by the shell fragment 332 on opposite face, make heat-conducting block 32 be in close contact lotus contact 1, in chopper work process, measure the temperature that Flos Nelumbinis limb 2 goes out more directly and accurately.
When temperature sensor 3 is dismantled, owing to shell fragment 332 has good elasticity, namely the opening that only need to increase "U" shaped structure detachably takes off.Visible temperature sensor of the present utility model 3 is convenient to disassembly.
The operation principle of this enforcement example: in work process, heat-conducting block 32 in temperature sensor 3 is by the temperature conduction on Flos Nelumbinis limb 2 to PCBA board 31, PCBA board 31 calculates the temperature on lotus petal sheet 2 according to the thermometer of conduction, draws the temperature at Flos Nelumbinis limb 2 place fast and accurately.
