Background technology
Be used for the thermal protector of the same type that refrigerant compressor uses in the prior art and mainly contain two kinds of structures; structure 1 as shown in Figure 1; it comprises pin 1; cover plate 2; liner 3; movable contact spring 4; moving contact 5; bimetal leaf 6; quiet pin 7; fixed contact 8; fixed contact supporter 9; fast connecting terminal 10; quiet pin 11; heater strip 12; base 13; its feature one is that fast connecting terminal 10 and quiet pin 11 are to be welded to connect; material cost improves like this increases welding procedure again one; behind simultaneously quiet pin 11 and base 13 riveteds, in welding fast connecting terminal 10 processes, easily cause quiet pin 11 and the loosening hidden danger of base riveted.Its feature two is that cover plate 2-1 and the base 13-1 indentation, there at fixed contact supporter 9 emersion positions has big slit behind cover plate 2 and base 13 riveteds; can make pernicious gas, humid air, impurity, contamination by dust contact surface like this; thereby the contact contact performance is reduced; might cause poor contact of contacts or not conducting phenomenon to take place; do not reach the purpose of protection compressor, but electric arc that produces can make the contact break-make simultaneously time the and the combustible that may exist or explosive gas cause burning or explode among a small circle on every side.
The utility model content
The purpose of this utility model is to provide that a kind of refrigerant compressor uses can stop the spark that factor such as quiet, moving contact action causes, explosion-proof type overload, the overheat protector that electric orphan is leaked effectively.
The concrete mode that realizes technical solutions of the utility model is such: comprising pin 1; cover plate 2; base 12; be installed on the liner 3 in the base 12; movable contact spring 4; moving contact 5; bimetal leaf 6; quiet pin 7; fixed contact 8; fixed contact supporter 9; fast connecting terminal 10; in the protector that heater strip 11 constitutes; on cover plate 2, be provided with the through hole 2-4 that passes for fixed contact supporter 9; fixed contact supporter 9 pastes and is upward through cover plate 2 along the inwall of base 12 and extends; between fixed contact 8 and fixed contact supporter 9; paste in the cover plate 2 and be provided with barrier wall 2-3 along fixed contact supporter 9; can stop quiet so effectively; the spark that factors such as moving contact action cause; impurity such as electricity orphan and dust leak from fixed contact supporter 9-1 position or invasion; and the surface of fast connecting terminal 10 is smooth and cover plate 2; the cooperation of base 12 is tight; cover plate 2 and fast connecting terminal 10 joint places and heater strip junction are equipped with the stopper 2-1 of barrier wall 2-2 and projection, can stop the spark that factor such as heater strip short circuit causes so effectively; impurity such as electricity orphan and dust leak from the fast connecting terminal position or invasion.
Explosion-proof type overload of the present utility model, overheat protector; changed the position that passes of fixed contact supporter; set up the stopper that fixed contact supporter barrier wall and fast connecting terminal joint place and heater strip junction are equipped with barrier wall and projection, can prevent effectively that the spark, the electric orphan that cause because of factors such as quiet, moving contact action, heater strip short circuits from these positions from leaking and the invasion of impurity such as dust.And have simple in structurely, installing and locating is easy, the characteristics that result of use is good.

Embodiment
Below in conjunction with embodiment the utility model is described further.Following embodiment only is used to illustrate the technical solution of the utility model, but to not restriction of the utility model.
Embodiment
The utility model mainly is made up of pin 1, cover plate 2, liner 3, movable contact spring 4, moving contact 5, bimetal leaf 6, quiet pin 7, fixed contact 8, fixed contact supporter 9, fast connecting terminal 10, heater strip 11, base 12.Heater strip 11 is welded on quiet pin 7 and the fast connecting terminal 10, and quiet pin 7, fixed contact supporter 9, fast connecting terminal 10 are contained in riveting jail on the base 12 respectively.Heater strip 11 evenly coils in base 12 die cavities, bimetal leaf 6 is contained in heater strip 11 upper bed-plates 12 die cavities, movable contact spring 4 is equipped with in bimetal leaf 6 tops, the head weldering moving contact 5 of movable contact spring 4, moving contact 5 contacts with fixed contact 8, movable contact spring 4 afterbodys and liner 3 welding, its assembly is welded on the quiet pin 7, constitutes the loop; Movable contact spring 4 is provided with protruding fat when guaranteeing bimetal leaf 6 action, and the contact reliably disconnects.After treating that running parameter meets the requirements, pack into cover plate 2 in the base 12 and with its riveting jail, pin 1 pack in the cover plate 2 and with fixed contact supporter 9 welding jails.
Behind base 13-1 place, the base 12-1 shown in Figure 2 place jagged assembling fixed contact supporter slit is arranged herein as shown in Figure 1, and the utility model base 12 shown in Figure 3 seamless herein after with position non-notch, assembling fixed contact supporter, avoided electric lonely the leakage and the intrusion of impurity such as dust.
As Fig. 3 cover plate 2 inwalls, this clear size of opening cooperates with fixed contact supporter 9-1 place size among Fig. 3, fixed contact supporter 9-1 passes from the through hole 2-4 of cover plate 2 when cover plate 2 assembles with base 12, the rivet tightly through hole 2-4 place of back shroud 2 is seamless, has avoided electric lonely the leakage and the intrusion of impurity such as dust.Fast connecting terminal 10 is different among Fig. 1 fast connecting terminal 10 and is welded to connect but one with quiet pin 11, be different from that fast connecting terminal 10 is provided with protruding fat point among Fig. 2, isostructure Fig. 1 compares and not only saves material but also reduced by one welding sequence, isostructure Fig. 2 and compared and do not have protruding fat point can avoid existing big slit herein on the fast connecting terminal 10 like this.
The barrier wall 2-2 that set up boss at cover plate 2 inwall places as shown in Figure 5, links to each other with boss 2-1 can stop effectively that like this impurity such as spark, electric orphan and dust that factor such as heater strip short circuit causes leak from the fast connecting terminal position or invasion.Set up A form drag barricade 2-3 and the through hole 2-4 that passes for Fig. 3 fixed contact supporter 9-1 is set at cover plate 2 inwalls, can stop effectively that like this impurity such as spark, electric orphan and dust that factor such as quiet, moving contact action causes leak from fixed contact supporter 9-1 position or invasion.Certainly the A form drag barricade 2-3 that sets up also can be other shapes such as in-line.
The utility model directly inserts connector post of refrigeration compressor in use, and is close to compressor case.When refrigerant compressor occurs making unusually operating current to increase or temperature raises, movable contact spring 4 open circuits are backed down in bimetal leaf 6 upset of being heated, and compressor cuts off the power supply.When temperature progressively dropped to the bimetal leaf recovery temperature, compressor started again.
