The invention has the advantages of high utilization rate of raw materials and low product cost.
Description
Technical field
The present invention relates to compressor protector, relate in particular to a kind of protector that is used for the single-phase compressor of air-conditioning refrigerating.
Background technology
The protector of present single-phase compressor all has airtight shell structure; the protector internal series-connection has temperature-sensitive element and heater strip of a band moving contact; electric current enters inside flow through temperature-sensitive element and heater strip by the binding post on the housing, and heater strip has played the effect of assistant heating to temperature-sensitive element when electric current flows through.When the thermal outside environment that produces on electric current is flowed through temperature-sensitive element and heater strip was transmitted to the temperature that under the inner hot acting in conjunction temperature-sensitive element is reached to set, the temperature-sensitive element band moving contact and is broken away from fixed contact, makes the loop outage; When the temperature of outside dropped to the temperature that sets, the temperature-sensitive element band moving contact contact fixed contact, and the loop is switched on again.What heater strip play a part in the whole protecting device mainly is assistant heating; heater strip mainly is to adopt the band material to carry out punching out processing at present, as depicted in figs. 1 and 2, adopts the band material to carry out punching out and adds man-hour; the utilization rate of raw materials of band material is only about about 36%, and utilance is extremely low.
Summary of the invention
The present invention is directed to the shortcoming of above-mentioned prior art, a kind of utilization rate of raw materials height, single-phase compressor protector that product cost is low are provided.
In order to solve the problems of the technologies described above; the technical solution used in the present invention is: a kind of single-phase compressor protector; comprise housing; described housing is provided with the first terminal and second terminal; described enclosure interior is provided with fixed contact, moving contact and temperature-sensitive element; described the first terminal and fixed contact conducting; described second terminal is by heating wire and temperature-sensitive element conducting; described temperature-sensitive element is fixed on the housing; described moving contact is fixed on the temperature-sensitive element and with fixed contact and is oppositely arranged, and described heater strip is that wire rod is made part.
Below technique scheme is further explained:
The two ends of described heater strip are flat.
Described housing is made up of interconnective substrate and case, and the described the first terminal and second terminal are by being fixedly arranged on the described substrate by electrical insulation.
Described temperature-sensitive element is fixed on the case by brace summer.
Described the first terminal is by stator and described fixed contact conducting.
Described the first terminal is by stator and described fixed contact conducting.
Advantage of the present invention is: heater strip of the present invention is that wire rod is made part, the direct brake forming of profile, the waste of material that has been caused when having avoided original band material blanking forming, by cold stamping technology line material two ends are flattened, thereby kept the flat end face of original connection, raw-material utilance can reach 100%.Thereby reduced product cost, had the advantage that the heater strip utilization rate of raw materials is higher, cost is lower.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples:

Embodiment
Embodiment:
As shown in Figure 3; the single-phase compressor protector of the embodiment of the invention comprises housing; housing is provided with the first terminal 4 and second terminal 5; enclosure interior is provided with fixed contact 7, moving contact 8 and temperature-sensitive element 9; the first terminal 4 and fixed contact 7 conductings, second terminal 5 is by heating wire 11 and temperature-sensitive element 9 conductings, and temperature-sensitive element 9 is fixed on the housing; moving contact 8 is fixed on the temperature-sensitive element 9 and with fixed contact 7 and is oppositely arranged, and heater strip 11 is made part for wire rod.
As shown in Figure 4 and Figure 5, the two ends of heater strip 11 are flat.Housing is made up of interconnective substrate 1 and case 2, and the first terminal 4 and second terminal 5 are by being fixedly arranged on the substrate 1 by electrical insulation 3.Temperature-sensitive element 9 is fixed on the case 2 by brace summer 10.The first terminal 4 is by stator 6 and fixed contact 7 conductings, and the first terminal 4 is by stator 6 and fixed contact 7 conductings.In the present embodiment, by substrate 1 and case 2 by welding the metal shell structure that fixedly constitutes a sealing, the first terminal 4 and stator 6 welding, fixed contact 7 is located on the stator 6, heating wire 11 1 ends and 5 welding of second terminal, the other end links to each other with housing case 2.
When processing heater strip 11, at first the wire rod raw material are passed through crooked, by cold stamping technology line material two ends are flattened then and formed the first flat connecting portion 11A and the second flat connecting portion 11B, the first flat connecting portion 11A is used for and 5 welding of second terminal, the second flat connecting portion 11B is used for linking to each other with housing case 2, thereby kept the flat end face of original connection, raw-material utilance can reach 100%.Thereby reduced product cost.
Should be pointed out that for the present invention also to have the embodiment of multiple conversion and remodeling, be not limited to the specific embodiment of above-mentioned execution mode through proving absolutely.The foregoing description is as just explanation of the present invention, rather than restriction.In a word, protection scope of the present invention should comprise those conspicuous to those skilled in the art conversion or substitute and remodeling.
