For finishing above-mentioned task, the technical solution of the utility model is: a kind of structure improved motor starter, comprise shell spare body 1 and a pair of electrical fitting that is separately positioned on the shell spare body 1, positive temperature coefficient thermistor 16 and a side cover 20, described shell spare body 1 one upper lateral parts have a uncovered resistor cavity volume 3, the top wall surface of resistor cavity volume 3 has fixed ear base 2, the below of resistor cavity volume 3 has extended protector cavity volume 13, in the opposite side of shell spare body 1 is formed with, outer pin chamber 7,8, outer pin chamber 12, interior pin chamber 9, interior pin chamber 7,9 and outer pin chamber 12 communicate with the external world through the wall body of shell spare body 1, and be furnished with fixed ear base 6 between also at the outer surface of this side, 10, in addition, along outside on the cavity in pin chamber 12, the below be formed with described resistor cavity volume 3 connect on, following contact groove 11,4; Described electrical fitting comprises upper and lower electrical fitting, last electrical fitting comprises and is positioned at the upper spring contact 15 of 28 1 ends and the inside and outside pin 27,26 of the other end in flakes, upper spring contact 15 places in the resistor cavity volume 3, inside and outside pin 27,26 is inserted in respectively in the inside and outside pin chamber 7,8, following electrical fitting comprises lower spring contact 17 and is arranged on the inside and outside pin 25,14 of lower spring contact 17 1 ends, lower spring contact 17 places in the resistor cavity volume 3, and inside and outside pin 25,14 is inserted in respectively in the inside and outside pin chamber 9,12; Positive temperature coefficient thermistor 16 places resistor cavity volume 3, and between upper and lower spring contact strip 15,17; Form fixedly ear 19,24,23 and outer pin jack 18,22, protector seat 21 on the described side cover 20; fixedly ear 19,24,23 is joined with described fixed ear base 2,10,6 buttons respectively; outer pin jack 18,22 is corresponding with outer pin 14,26 respectively and communicate; and the seat chamber of protector seat 21 is a T shape, and corresponding with protector cavity volume 13.
The utility model extends useful for the protector pin chamber 5 that plugs protector pin 29 below shell spare body 1 close inside and outside pin chamber 7,8.
Advantage of the present utility model: need not connecting line and on the terminal of the compressor electric motor of can directly planting, simple in structure, electrical fitting is provided with rationally, volume is little; Can also for being provided with motor protecter, the compressor electric motor protective circuit provide mounting condition effectively.
Accompanying drawing and drawing explanation
Accompanying drawing is the assembling assumption diagram of the utility model motor starter.
Embodiment
See accompanying drawing; the shell spare body 1 that is provided by the applicant preferably adopts the plastic moulding moulding; when molded and shaped, the resistor cavity volume 3 on it, protector cavity volume 13, fixed ear base 2,10,6, upper and lower contact groove 11,4, interior pin chamber 7,9, outer pin chamber 8,12 and 5 in protector pin chamber are shaped on the shell spare body 1.Equally, the side cover 20 that is provided by the applicant also preferably adopts the plastic moulding moulding, and when molded and shaped, outer pin jack 18,22, fixedly ear 19,23,24,21 of protector seats are integrally formed on the side cover 20.
The utility model is assembled like this, the upper wall of upper spring contact 15 along resistor cavity volume 3 is inserted in the resistor cavity volume 3, at this moment, in flakes 28 along last contact groove 11 notches enter into bottom land, inside and outside pin 27,26 is embedded in the inside and outside pin chamber 7,8 suitably; The lower wall of lower spring contact 17 along resistor cavity volume 3 is inserted in the resistor cavity volume 3, and at this moment, 30 along down contact groove 4 notches enter into bottom land, inside and outside pin 25,14 is embedded into respectively in the inside and outside pin chamber 9,12 suitably in flakes.Shown in figure, positive temperature coefficient heat sensor 16 is laid respectively between the upper and lower spring contact strip 15,17 in the resistor cavity volume.By figure so that as can be known, side cover 20 by the fixedly ear on it 19,23,24 respectively with shell spare body 1 on fixed ear base 2,6,10 be interlocked, by this side cover 20 is attached on the shell spare body 1.Outer pin jack 18,22 on the side cover 20 is respectively in alignment with outer pin 14,26, and outer pin 14,26 is for external power leading-in terminal and its inserting.As aforementioned, interior pin chamber 7,9, outer pin chamber 12 and protector pin chamber 12 are to see through the wall body of shell spare body 1 and exterior, and therefore, interior pin 27,25 and interior pin 14 and protector pin 29 also communicate with the external world.
By foregoing description as can be known, in the compressor protection circuit, except using motor starter; generally also in the main circuit of compressor, be in series with motor protecter; the effect of motor protecter is when on the low side or refrigerating system breaks down when supply voltage, to be cut off the electricity supply by it, uses the protection compressor.Just considering that in this protector cavity volume 13 that is extended, protector pin chamber 5 and the protector seat 21 that extends provide convenience for body shape is installed for the motor protecter of T shape just on side cover 20 on shell spare body 1 of the present utility model.
The utility model that finishes by above-mentioned assembling in use, as long as by the connecing on the post of compressor of planting of the interior pin 27,25 in the pin chamber 7,9 in being inserted in respectively, even also compressor electric motor electric connects post and insert respectively and wherein realize being electrically connected.Be in the conducting state of little resistance at normal temperatures because of positive temperature coefficient thermistor 16, and when compressor electric motor starts, electric current is by positive temperature coefficient thermistor 16, connect the compressor electric motor starting circuit, the starting of help compressor electric motor, while is in the moment of compressor electric motor starting, because of the electric current positive temperature coefficient thermistor 16 of flowing through makes its rapid heating, and can make positive temperature coefficient thermistor 16 reach the high value state in a short period of time, thereby cut off the starting circuit of compressor electric motor, make compressor electric motor enter normal operating conditions.Install motor protecter in this way additional, so, as long as with the protector main body along for accommodation in the protector cavity volume 13, and be electrically connected with protector pin 29 etc. and get final product.
