Embodiment
Referring to Fig. 1, Fig. 2, shown in Figure 3, the built-in protector of a kind of compressor is formed integral structure by temperature, current controling element 1, fast plug receptacle 2, fast connecting terminal 3, insulated bearing plate 4.Control element 1 is provided with metal shell 11, metal shell 11 is connected with thermosensitive bimetal 12 1 ends with conducting strip 15 1 ends, be welded with moving contact 13 on thermosensitive bimetal 12 other ends, the fixed contact 14 corresponding with moving contact 13 is fixedly welded on the 2nd exit 17 inner ends.Conducting strip 15 other ends are connected the 1st exit 16 inner ends.Fixing between the 1st exit 16 and the 2nd exit 17 and the metal shell 11 with the glass ceramics insulation, like this, the 1st exit 16, conducting strip 15, metal shell 11, thermosensitive bimetal 12, moving contact 13, fixed contact the 14, the 2nd exit 17 just connect into a string circuit.The outer end that the 1st exit 16 stretches out metal shell 11 is welded with the outer end that fast plug receptacle 2, the 2 exits 17 stretch out metal shell 11 and is welded with fast connecting terminal 3.Have aperture 2-1 and 3-1 on brace 2-2, the 3-2 of fast plug receptacle 2, fast connecting terminal 3, use rivet 18 and 5 riveted and fixed respectively with two aperture 4-4 and 4-2 corresponding on the insulated bearing plate 4.Thereby realize that compressor protector is integrated.In the present embodiment, select plastic insulation support plate 4 for use, be provided with opening vertical slot 4-3 in its left front end, closely connect with fast plug receptacle 2, patch rigidity, have a big breach 4-1 at its rear portion to strengthen it, to improve the sensitivity of control element 1, also can reduce the material consumption, reduce production costs.
The course of work of the built-in protector of this compressor is as follows:
