Embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is described in detail.
Temperature switch comprises input conducting sheet 10, insulation every stops, bimetal leaf 30 and output conducting sheet 40 as shown in Figure 1, and input conducting sheet 10 is fixedly connected every stops and output conducting sheet 40 by insulation.Bimetal leaf 30 comprises first end and the second end, first end is fixedly connected with input conducting sheet 10, the second end when temperature is lower than reset temperature with output conducting sheet 40 conductive contacts, the second end disconnects with output conducting sheet 40 when temperature is higher than break-off signal, and when temperature is between recovery temperature and the break-off signal, the second end remains open state with output conducting sheet 40, until temperature is lower than recovery temperature.Input conducting sheet 10 arranges the adjusting salient point, and it is corresponding with bimetal leaf 30 to regulate salient point.
Temperature switch also comprises insulating base 20, and input conducting sheet 10 is embedded in the insulating base 20, and insulating base 20 is formed in one every stops with insulation.Insulating base 20 is arranged on the output conducting sheet 40, and an end of output conducting sheet 40 is provided with several insulating base 20 is installed fastening locking pawl 420.Be wrapped with at insulating base 20 and seal shell, seal the sealing of shell epoxy available, with improve temperature switch sealing property and anti-pressure ability.
Wherein, at the second end solder contacts of bimetal leaf 30, regulate solder contacts on the salient point 410 at movable contact, the present embodiment temperature switch just can be used as the usefulness of major loop overtemperature protection.
When production test, temperature switch is placed on the temp. controllable heating board, and the temperature of adjusting temp. controllable heating board is reset temperature.To export conducting sheet 40 and input conducting sheet 10 and be connected to the break-make detecting instrument.Microcomputer-controlled step motor drives top predeformation amount adjusting salient point 110 under the temperature adjustment thimble, and predeformation amount is regulated the variation of salient point 110 projection amount and also pressed bimetal leaf 30 in the top, so that the crooked radian of bimetallic 30 changes.Bimetal leaf 30 rapid jumping under the double action of temperature and predeformation amount adjusting salient point 110 broken, and after the break-make detecting instrument detects break signal, moves on the microcomputer-controlled step motor drive temperature adjustment thimble, determines the height of projection of predeformation amount adjusting salient point 110.
Equally, temperature switch is placed on the temp. controllable heating board, and the temperature of adjusting temp. controllable heating board is break-off signal.To export conducting sheet 40 and input conducting sheet 10 and be connected to the break-make detecting instrument.Microcomputer-controlled step motor drives and pushes up the adjusting salient point 120 that resets under the temperature adjustment thimble, resets to regulate the second end of the variation of salient point 120 projection amount and top pressure bimetal leaf 30, so that the crooked radian of bimetallic 30 changes.Bimetal leaf 30 is in temperature and jump rapidly disconnectedly under the double action of regulating salient point 120 that resets, and behind the break-make detecting instrument detection path signal, microcomputer-controlled step motor drives on the temperature adjustment thimble and moves, and determines to reset to regulate the height of projection of salient point 120.
The below describes advantage or the principle of present embodiment.
1, no matter which kind of state bimetal leaf 30 is under, the adjusting salient point all can withstand bimetal leaf 30 makes it that certain predeformation occur, so that bimetal leaf 30 can be realized the zero propagation redirect when carrying out redirect, simultaneously, the existence of salient point is also effective must to have prevented that the void of bimetal leaf 30 is tactile owing to regulate, and improves the product percent of pass of temperature switch.
2, only have input conducting sheet 10, output conducting sheet 40, bimetal leaf 30 and insulating base 20 these four parts to form, simple in structure, its volume can be controlled very littlely and thin, be convenient to be installed in the place of limited space.
3, seal when installing, locking pawl 420 tips upside down at insulating base 20 and gets final product, and is convenient to the flanging assembling.
The above embodiment has only expressed several execution mode of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.
