Abstract
A motor starting and protector shell body with improved structure improves the motor staring and protector shell body of the present motor starting and overload protecting functions for a refrigeration compressor. The utility model includes a shell cover and a base seat. The shell cover is provided with three jacks, and the surrounding of the three jacks respectively forms guidance cavity, and the jack is in the bottom of the guidance cavity. Because the surrounding of every jack respectively forms the guidance cavity, so the jack can be guided quickly and precisely through the guidance cavity to a trilinear column of the compressor, which is helpful for the installment speed to install the shell cover and the base seat to the trilinear column of the compressor.
Description
Technical field
The utility model relates to a kind of electric motor starting of structure, housing of protector of improving, and is the improvement that is used for the housing of electric motor starting, protector to starting of the motor of refrigerant compressor and overload protective function to existing.
Background technology
In the starting circuit of refrigerant compressor, be in series with starter, it is to utilize the positive temperature coefficient thermistor of protector to be in little resistance conducting state at normal temperatures, and when compressor electric motor energising starting, electric current is connected the starting circuit of compressor through positive temperature coefficient thermistor and the inserted sheet corresponding with positive temperature coefficient thermistor, make the refrigeration compressor motor starting, simultaneously, in the moment of the electric motor starting of compressor, the electric current of positive temperature coefficient thermistor of flowing through makes the positive temperature coefficient thermistor heating rapidly, thereby make positive temperature coefficient thermistor reach the high value state in a short period of time, cut off the starting circuit of compressor, make compressor enter normal operation; The function that is connected on the protector in the main circuit of compressor electric motor is when on the low side or refrigerating system breaks down when supply voltage, to be cut off the electricity supply the protection compressor electric motor by it.Operation principle and concrete structure for electric motor starting, protector also can be by being seen in (this patent is also proposed by the applicant) in the disclosed electric motor starting of Chinese patent ZL03219606.7, the protector technical scheme.
The applicant finds; the shell structure that comprises electric motor starting in the prior art of above-mentioned patent, protector is by shown in Figure 1; it comprises cap 1 and pedestal 2; the jack 11 that goes on three terminals that offer three compressors that are used to plant on the cap 1, jack 11 are and insert three pins corresponding (seeing ZL03219606.7 for details) in the seat chamber that is embedded in pedestal 2.Be not difficult to find, if cap 1 is taken on three terminals of pedestal 2 (both assemblings the finish back) compressor of planting, comparatively trouble operates, because be the known fact, the awkward position that the position of three terminals of compressor is in space-constrained and can't be directly watched by sight line is felt with erector's feel entirely, therefore for jack 11 is inserted on three terminals, often need repeatedly mobile cap 1, until making jack 11 seek three terminals, thereby caused installation exercise slowly.
Summary of the invention
Task of the present utility model is will provide a kind of can rapidly and accurately cap be taken the electric motor starting of the improvement structure that three terminals that pedestal is installed to compressor get on, the housing of protector.
Task of the present utility model is finished like this; a kind of electric motor starting of structure, housing of protector of improving, it comprises cap 1 and pedestal 2, offers three jacks 11 on the cap 1; constitute directed cavity 111 respectively around described three jacks 11, jack 11 occupy the bottom of directed cavity 111.
Directed cavity 111 described in the utility model be shaped as spherical chamber, described jack 11 occupy the bottom in spherical chamber.
Directed cavity 111 described in the utility model be shaped as basin shape chamber, described is the bottom that jack 11 occupy basin shape chamber.
Directed cavity 111 described in the utility model be shaped as the infundibulate chamber, described is the bottom that jack 11 occupy the infundibulate chamber.
Jack 11 described in the utility model occupy the bottom center in spherical chamber.
Jack 11 described in the utility model occupy the bottom center in basin shape chamber.
Jack 11 described in the utility model occupy the bottom center in infundibulate chamber.
The utility model is owing to constitute directed cavity 111 respectively around each jack 11, therefore, jack 11 is led and fast and accurately to three terminals of compressor, help improving cap 1 is taken installation rate on three terminals that pedestal 2 is installed to compressor.
Description of drawings
Fig. 1 is the electric motor starting in the prior art, the shell structure figure of protector.
Fig. 2 improves the example structure figure of housing of electric motor starting, the protector of structure for the utility model.
Embodiment
In Fig. 2, cap 1 by the hasp that extends on it 12 with extend the parts (not shown) that scoops out that being used on the wall body of pedestal 2 scoop out hasp 12 and be interlocked.Specifically be, after in the corresponding cavity volume that will be assemblied in pedestal 2 such as positive temperature coefficient thermistor, inductance, resistance, controllable silicon, pin, cap 1 is fastened by the hasp 12 and the parts that scoop out on the pedestal 2, take on three terminals that pedestal 2 is assembled to freezer compressor by cap 1 then.
Seen that by Fig. 2 respectively constitute a directed cavity 111 around three jacks 11, the cavity diameter of directed cavity 111 is by greatly gradually little, jack 11 occupy the bottom of directed cavity 111 central authorities.Whole directed cavity 111 is a mortar shape, and the mortar shape of promptly husking rice with mortar and pestle is more particularly that spherical chamber or title are basin shape chamber or title is the infundibulate chamber, and directed cavity 111 is shaped when being shaped with cap 1.
When mounted, although the operator can not be by three terminals that observe visually compressor, but because the guide effect of directed cavity 111, can fast and exactly visit and reach to three terminals, thus make be positioned at directed cavity 111 bottom center positions jack 11 soon inserting to three terminals.
The applicant has carried out the comparative test; by same assembler the prior art structure is also promptly assembled by the housing of electric motor starting shown in Figure 1, protector three terminals to compressor; and then use three terminals of the utility model structure and compressor to assemble; found that the efficiency of assembling in the unit interval can improve 3-5 doubly, therefore positive effect of the present utility model is ultimate attainment.
