Description
The utility model relates to a kind of protector, particularly a kind of compressor thermal protector, and it is applicable to that mainly refrigerator and compressor of air conditioner cross the protection of temperature rise, overcurrent.
The structure of similar compressor thermal protector of the prior art as shown in Figure 1 and Figure 2, it mainly by bimetal leaf 2 ', moving contact 3 ', housing 5 ', adjusting screw(rod) 7 ', quiet pin 4 ', 8 ', 13 and heating wire 12 ' etc. form.Have a pair of contact 3 ' a heat-resisting housing of anti-combustion the 5 of circle of butterfly shaped dual metal sheet 2 ' be installed in ' in, adjusting screw(rod) 7 ' screw-in housing 5 ' the screw relevant position, butterfly shaped dual metal sheet 2 ' dependence adjusting screw(rod) 7 ' corresponding interval location, and in adjusting screw(rod) 7 ' end with packing ring 1 ', make butterfly shaped dual metal sheet 2 ' fixed-site with its riveted.Butterfly shaped dual metal sheet 2 ' below be equipped with heating wire 12 ', the quiet pin 8 of heating wire 12 ' be welded in ' and quiet pin 13 ' on, with heating wire weldment assembly and quiet pin 4 ' be riveted on housing 5 ' in, quiet pin 4 ', 8 ' serve as the moving contact 3 of fixed electrode and butterfly shaped dual metal sheet ' corresponding.Aborning for reaching the required running parameter of thermal protector, except that prefabricated corresponding butterfly shaped dual metal sheet 2 ', and under rated condition, rotate adjusting screw(rod) 7 ', wait to meet the requirements afterwards with glue seal adjusting screw(rod) 7 '; The circuit of thermal protector connects by being connected and fixed plate 6 ' and pin 11 ' reach fast, fixed head 6 ' be connected with quiet pin 4 ' spot welding, go between 10 ' by with pin 11 ', constitute lead assemblies behind geometrical clamp 9 ' riveted, and with quiet pin 13 ' welded; These two welding assemblies are all used the epoxide-resin glue sealing, in case the unpredictable factor that occurs in the circuit connection procedure.During use; thermal protector is close on the shell of hermetically sealed compressor, when compressor passed through excessive electric current, the big heat of heating wire 12 ' moment generation caused butterfly shaped dual metal sheet 2 ' bending upset; and make moving contact 3 ' disconnection, play the protective effect of overload current.In addition; when compressor for a certain reason the duration of runs long; cause the compressor housing temperature too high, add and impel the upset of butterfly shaped dual metal sheet 2 ' heated bending after heating wire 12 ' generation heat superposes and make moving contact 3 ' disconnection, played the protective effect of temperature rise.Because of overcurrent and cross the bimetal leaf 2 of the crooked upset of temperature rise ', be lower than the reset temperature of bimetal leaf 2 ' setting when residing ambient temperature after, bimetal leaf 2 ' can automatically reset makes the thermal protector rearming.But still there is following shortcoming in actual use in this compressor thermal protector: 1, structural design is reasonable inadequately, installs loaded down with trivial details: need during installation to locate by the spring clip; 2, installation cost height: owing to increased the spring clip and make annex, and thermal protector is installed on the compressor housing of binding post side, increased the plastic shell volume; 3, running parameter easily drifts about: because bimetal leaf itself is switched on and had two moving contacts, temperature parameter is subjected to the influence of inner heating power of bimetal leaf and contact wearing and tearing bigger; 4, temperature-sensitive poor-performing: because bimetal leaf shrinking away from theshell body end face still has certain distance, be installed on the compressor housing even be close to, case temperature will be sensed needs longer a period of time of air transmitted on the bimetal leaf, the temperature protection performance is produced certain influence.
The purpose of this utility model is to overcome existing above-mentioned deficiency in the prior art, and the compressor thermal protector of a kind of reasonable in design, simple installation and long service life is provided.
The purpose that the utility model proposed can be achieved through the following technical solutions: this thermal protector comprises bimetal leaf; heating wire; moving contact and quiet pin; its design feature is also to be provided with cover plate; pin; base; movable contact spring and fixed contact and the quick quiet pin of inserted sheet; cover plate and base are fixed; pin is installed on the cover board; bimetal leaf is located in the base; under it heating wire is housed; movable contact spring is equipped with in the top of bimetal leaf; have moving contact on the movable contact spring; this moving contact contacts with fixed contact; the quiet pin of inserted sheet fuses fast, and is provided with fat point on the quiet pin of this quick inserted sheet.
The utility model fixed contact is welded on the quiet pin, and moving contact is cross with contacting of fixed contact.
The afterbody of the utility model movable contact spring and liner welding, the movable contact spring assembly is welded on the quiet pin, and is provided with protruding fat on movable contact spring.
The utility model is provided with boss at base intracavity, and it and base fuse.
The utility model has on the cover board designed center positioning hole.
The utility model compared with prior art has the following advantages and effect: 1, reasonable in design, simple installation, need not use the spring clip, can directly be connected, and the installation position volume be little with the compressor wiring post, make the volume-diminished of case thus, reduced the installation accessories cost.2, owing to the obstructed overcurrent of bimetal leaf, running parameter is stable, has prolonged useful life.3, can sense the compressor internal temperature more exactly, if any undesired user mode is arranged, all energy fast reactions are because thermal protector is contacting of metal to metal with the way of contact of compressor wiring post.4, owing to the quick quiet pin of inserted sheet fuses, and which is provided with fat point, so compact conformation, processing technology is convenient, and production efficiency is higher.
