Compared with the prior art, the single-contact external compressor protector has a simple structure and components are convenient to process and assemble, thereby further reducing the production cost and failure risks of the products, achieving dual-protection for temperature and current, achieving high reliability, and further improving the quality and application safety of the product.
Description
Technical field
The present invention relates to the electric components technical field, especially a kind ofly be applicable to single-phase single contact external compressor protector.
Background technology
Compressor protector is a kind of device to automatically replying after the automatic protection of compressor; Protector is according to the temperature of coil and the size variation of motor current; With the bimetal leaf behind the temperature-sensitive as thermal reaction element, when the compressor non-normal working along with electric current and compressor coil temperature be increased to set temperature value the time, bimetallic element starts rapidly; Open the contact, cut off the electricity supply.The contact auto-closing recovers the policy operating state when bimetallic element is cooled to safe temperature, and this has the double protection of electric current and temperature to compressor.The external compressor protector is mainly used on the compressors such as refrigerator, small-power air-conditioning, because protector adopts non-closed structure, generally is installed on the compressor head outside.Present most of external protector all adopts the double-contact symmetrical structure, because it is simple in structure, installing and replacing conveniently is widely used.
The problem that the external protector of prior art exists is: bimetal leaf adopts two silver contacts of noble metal, cause manufacturing cost high, and the parts of temperature correction is many, causes assembly process complicated, and reliability of products is poor.
Summary of the invention
A kind of single contact external compressor protector that the objective of the invention is to be directed against the deficiency of prior art and design; Adopt the single-contact temperature-sensitive temperature-sensitive element of cantilever type, realize the duplicate protection of temperature and electric current, simple in structure; Parts processing and easy to assembly; Further reduce production costs failure risk with product, reliability is high, has further improved the quality of product and safe in utilization.
The objective of the invention is to realize like this: a kind of single contact external compressor protector; Comprise the pedestal box, bimetal leaf, short circuit stitch, long leg, first pin and second pin that are provided with cover plate; Be characterized in that said bimetal leaf is that an end is provided with moving contact, the other end is provided with the arc plate of welding hole; Said short circuit stitch is " L " shape electrical connector that is provided with fixed contact; Said long leg is " L " shape electrical connector that is provided with cantilever, and said cantilever both sides are provided with groove; Short circuit stitch and long leg one end rivet clasp are in the cavity of pedestal box, and its other end stretches out the pedestal box and welds with first pin and second pin respectively; Bimetal leaf one end is by the cantilever welding of weldering nail through welding hole and long leg, the fixed contact elasticity crimping of other end moving contact and short circuit stitch.
Said weldering nail is for being provided with the circular weld piece of big convex closure and several little convex closures, and its big convex closure is the concentric circles setting with several little convex closures.
Said moving contact adopts silver contact and bimetal leaf to be welding.
Said several little convex closures and bimetal leaf welding, said big convex closure and the welding of length leg, said big convex closure are welded as with long leg and bimetal leaf with several little convex closures to be carried out and once completion simultaneously.
The present invention compared with prior art has simple in structure, and parts processing is with easy to assembly, and the failure risk with product of further reducing production costs is realized the duplicate protection of temperature and electric current, and the reliability height has further improved the quality of product and safe in utilization.

Embodiment
Below will do further elaboration to the present invention through concrete embodiment:
Embodiment 1
Consult accompanying drawing 1, the present invention is by the pedestal box 1 that is provided with cover plate 5, bimetal leaf 4, short circuit stitch 2, long leg 7, first pin 8 and second pin 9, and said bimetal leaf 4 is that an end is provided with moving contact 3, and the other end is provided with the arc plate of welding hole 41; Said short circuit stitch 2 is for being provided with " L " shape electrical connector of fixed contact 21; Said long leg 7 is for being provided with " L " shape electrical connector of cantilever 71; One end rivet clasp of short circuit stitch 2 and long leg 7 is in the cavity of pedestal box 1, and cover plate 5 snaps onto and constitutes a seal chamber on the pedestal box 1, and the other end of short circuit stitch 2 and long leg 7 stretches out pedestal box 1 and welds with first pin 8 and second pin 9 respectively; Bimetal leaf 4 one ends follow closely 6 through cantilever 71 welding of welding hole 41 with long leg 7 by weldering, the fixed contact 21 elasticity crimping of other end moving contact 3 and short circuit stitch 2, and making wins forms current path between the pin 8 and second pin 9.
Consult accompanying drawing 2, said bimetal leaf 4 is that an end is provided with moving contact 3, and the other end is provided with the arc plate of welding hole 41, and moving contact 3 adopts silver contact and bimetal leaf 4 to be welding.
The present invention uses like this: the gradient of at first adjusting cantilever 71 according to the operating current of compressor; The curved design temperature of i.e. adjustment length leg 7 side grooves 72 with 4 take-offs of adjustment bimetal leaf; Then; The present invention is arranged on compressor end covers, cover plate 5 is affixed on the heating position of compressor head, and first pin 8 and second pin 9 are serially connected in the compressor circuit.When the heat that under the function of current, produces when compressor head temperature and bimetal leaf 4 reaches design temperature; Bimetal leaf 4 is opened the elasticity crimping of moving contact 3 and fixed contact 21, cuts off the working power of compressor, when bimetal leaf 4 temperature are reduced to a certain design temperature; Bimetal leaf 4 resets again; The elasticity crimping of closing contact 3 and fixed contact 21, the working power of conducting compressor realizes temperature and electric current duplicate protection.
More than just the present invention being further described, is not in order to the restriction this patent, all for the present invention's equivalence enforcement, all should be contained within the claim scope of this patent.
