Detailed description of the invention
For the ease of the understanding of those skilled in the art, being further described this utility model with accompanying drawing below in conjunction with embodiment, the content that embodiment is mentioned is not to restriction of the present utility model.Below in conjunction with accompanying drawing, this utility model is described in detail:
Embodiment 1: see Fig. 1, Fig. 2.A kind of temperature protection plug, including:
Shell body 3, the one side indent of shell body 3 forms containing cavity；One end of shell body 3 connects the lug 1 having flexibility, and lug 1 connects in hollow structure and with containing cavity；
3 inserted sheets, respectively ground wire inserted sheet 2, live wire inserted sheet 4 and zero line inserted sheet 5；
The cover plate 6 matched with containing cavity, cover plate 6 is provided with 3 jacks, and corresponding jack is stretched out in the outer end of inserted sheet, and the inner of inserted sheet is positioned at containing cavity；
Article 3, cable, one end of cable passes lug 1 and stretches into containing cavity, and the inner of inserted sheet connects with corresponding cable respectively；
It is provided with temperature switch 7 between the inner of at least one of which inserted sheet with corresponding cable, and the inner of this inserted sheet is connected with cable by temperature switch 7.
After arranging temperature switch 7, can be monitored the temperature of plug, after predetermined temperature got to by temperature switch 7, temperature switch 7 disconnects, thus protects plug and corresponding socket, it is to avoid cause fire.
Temperature switch 7 can use physical switch, and such as two bonding jumpers be arrangeding in parallel, the inside lateral bend in end of one of them bonding jumper, the part of bending overlaps with another bonding jumper.When temperature rises to predetermined value, bonding jumper deforms upon, and two bonding jumpers separate.Can also use the temperature switch of electric fuse class, once temperature reaches predetermined value, blown fuse.Temperature switch 7 can also use electronic temperature control to switch.
Further, described temperature switch 7 is connected with the inner of zero line inserted sheet 5.
The most a lot of electrical equipment is desirable that earth lead, to prevent short circuit；Therefore all there is inside electrical equipment the MCU whether detection zero line connects.Here temperature switch 7 is connected to the inner of zero line inserted sheet 5, controls the break-make of zero line；When occurring that loose contact causes temperature to raise, temperature switch 7 disconnects, and now the MCU within electrical equipment detects that zero line disconnects, then close electrical equipment.
Due to different areas or occasion, it is desirable to break-off signal different, it is therefore desirable to make temperature switch 7 adjustable, temperature switch 7 now uses electronic temperature control to switch, being controlled by MCU, temperature switch 7 now should not be connected with live wire, zero line, prevents from being disturbed by forceful electric power.
Further, the medial surface of described cover plate 6 extends internally the U-board 62 and side plate 61 being oppositely arranged, and forms the accommodation space for housing temperature switch 7 between U-board 62 and side plate 61, and temperature switch 7 is fixed on accommodation space.
Temperature switch 7 is arranged at accommodation space, can conveniently be fixed.Leave gap between U-board 62 and side plate 61, it is simple to inner by zero line inserted sheet 5 inserts and be connected with temperature detect switch (TDS) simultaneously.Preferably, the inner of ground wire inserted sheet 2 is outward extended with contact 21, and contact 21 is connected through gap with temperature switch 7.
Further, live wire inserted sheet 4, the inner of zero line inserted sheet 5 are equipped with U-shaped and connect sheet 42.
U-shaped is set and connects sheet 42, it is simple to be connected with cable.During connection, U-shaped is connected sheet 42 and surrounds the end blocking cable.
Further, live wire inserted sheet 4, the inner of zero line inserted sheet 5 are equipped with hole clipping 41, the medial surface of described cover plate 6 is provided with two groups of fixed plates 64 matched respectively with live wire inserted sheet 4, zero line inserted sheet 5, often group fixed plate includes two fixed plates be arrangeding in parallel 64, and the medial surface of fixed plate 64 extends internally the projection 63 matched with hole clipping 41.
Hole clipping 41 and projection 63 are set, it is simple to fixing live wire inserted sheet 4, zero line inserted sheet 5；Live wire inserted sheet 4, zero line inserted sheet 5 are in use simultaneously, and projection 63 produces thrust to it, it is to avoid live wire inserted sheet 4, zero line inserted sheet 5 produce greater impact power to plug inside.
Embodiment 2: see accompanying drawing 3; a kind of temperature protection electrical equipment; plug is protected including said temperature; also include the MCU for detecting ground wire break-make and control switch; MCU electrically connects with the control portion controlling switch, and the switch portion controlling switch is connected with the equipment of electrical equipment, when MCU detects ground wire open circuit; MCU sends cut-off signal to control portion, and control portion controls switch portion and disconnects.
Controlling switch can be closed type electromagnetic relay；When temperature protection plug occurs that temperature is too high, ground wire open circuit, MCU controls control and switches off.Here equipment can be motor, compressor etc..
The above, it it is only this utility model preferred embodiment, not this utility model is made any pro forma restriction, although this utility model is open as above with preferred embodiment, but it is not limited to this utility model, any those skilled in the art, in the range of without departing from technical solutions of the utility model, when the technology contents utilizing the disclosure above makes a little change or is modified to the Equivalent embodiments of equivalent variations, in every case it is without departing from technical solutions of the utility model content, any simple modification that above example is made is referred to according to this utility model technology, equivalent variations and modification, belong in the range of technical solutions of the utility model.
