Abstract

The invention discloses an external type compressor protector which comprises a base with a box cover, wherein a thermo-sensitive element and a connection pin are arranged in the base; the thermo-sensitive element is in elastic compression connection with one end of the connection pin through a screw with a spring; and the other end of the connection pin extends out of the base to be welded with an insertion piece. The external type compressor protector provided by the invention has the characteristics that a first major arc edge with a string and a groove are arranged on the inner circle port of the base; and the box cover is a cover plate which is provided with a second major arc edge with a string and a bending structure or a spring structure, and the bending structure or spring structure is in insertion connection or in clamping connection with the groove so that the box cover is fixedly arranged on the base. Compared with the prior art, the external type compressor protector disclosed by the invention is simple in structure and reliable in connection, thereby greatly avoiding quality accidents that the conductivity of a product is poor due to fixation of glue or the cover plate falls and is inversely installed due to ageing, reducing the risk of product failure and further improving the quality and application security of the product.

Description

A kind of external compressor protector

Technical field

The present invention relates to the electric components technical field, especially a kind ofly be applicable to single-phase external compressor protector.

Background technique

The single-phase compressor protector generally all has cover plate; Cover plate has mainly played effect dustproof and that keep internal heat, for fixing of cover plate, at present; The general method that all adopts glue to solidify; Through glueing joint the structure that fixedly constitutes a sealing, this fixation method exists following defective and problem: when brushing glue, might glue be got into product inside, will cause the product circuit can't conducting between the product contact when glue is clipped in; In addition, after product uses for a long time, descend, cover plate is come off, the accident of harm such as generation electric leakage personal safety owing to factors such as glue is aging can cause glue viscosity.

Summary of the invention

A kind of external compressor protector that the objective of the invention is to be directed against the deficiency of existing technology and design; Adopt bending or the elastic piece structure and the major arc limit of cover plate; The realization lid is fixedly connected with the pedestal box; Major arc limit structure is used for the effect that the automatic production process is differentiated the cover plate direction, can play preventing that the cover plate dress is anti-, has greatly avoided causing the product conduction bad or because the aging problem that causes cover plate to come off because of glue fixing; Reduce the failure risk of product, further improved the quality of product and safe in utilization.

The objective of the invention is to realize like this: a kind of external compressor protector, comprise the pedestal that is provided with lid, be provided with thermosensitive element and connecting pin in the pedestal; Connecting pin and pedestal riveted fixing; Thermosensitive element is by the end elasticity crimping with itself and connecting pin of the screw of pocketed springs; The other end of pin welds inserted sheet after stretching out pedestal; Fastening after screw is threaded with the embedded nut of pedestal by nut, be characterized in that the interior nose circle mouth of pedestal is provided with first major arc limit and the groove of band string; Lid is to be provided with the second major arc limit of band string and the cover plate of bending or reed structure, and bending or elastic piece structure and groove are pegged graft or clamping, and the realization lid is fixedly connected with pedestal.

The said first major arc limit cooperates for complementary band string is circular with the second major arc limit.

Said groove is to be symmetricly set on the interior nose circle mouth of pedestal.

Said bending structure is the circumferential edges that is symmetricly set on lid, and the plastic deformation of its bending structure launches the back makes lid be fixedly connected with pedestal with the groove grafting.

Said elastic piece structure is to be symmetricly set on the circumferential edges of lid, and its elastic piece structure makes lid be fixedly connected with pedestal with the groove flexible clamping.

The present invention compared with prior art has simple in structure; Connect reliable; Greatly avoided reducing the failure risk of product, further improved quality of product and safe in utilization because of glue fixing causes product conduction bad or owing to agingly cause cover plate to come off and cover plate is adorned anti-Accident due to quality.

Embodiment

Below will do further elaboration to the present invention through concrete embodiment:

Embodiment 1

Consult accompanying drawing 1; The present invention includes: comprise the pedestal 5 that is provided with lid 4; Lid 4 is for being provided with the cover plate on the bending structure 41 and the second major arc limit 43, and the interior nose circle mouth 52 of pedestal 5 is provided with the first major arc limit 53 and groove 51 of band string, is provided with thermosensitive element 10 and connecting pin 2 in the pedestal 5; Connecting pin 2 and pedestal 5 riveted fixing; Thermosensitive element 10 by the screw 6 of pocketed springs 9 with of the end elasticity crimping of its movable contact 3 with connecting pin 2; The other end of pin 2 stretches out pedestal 5 back welding inserted sheets 1; Screw 6 back that is threaded with embedded nut 8 on being arranged on pedestal 5 is fastening outside pedestal 5 by nut 7; Bending structure 41 is pegged graft with groove 51 lid 4 is fixedly installed on the pedestal 5, and realization lid 4 is fixedly connected with pedestal 5.

Consult accompanying drawing 2 ~ accompanying drawing 3, the interior nose circle mouth 52 of pedestal 5 is provided with the first major arc limit 53 and groove 51 of band string, and groove 51 is on two interior nose circle mouths 52 that are symmetricly set on pedestal 5.

Consult accompanying drawing 4 ~ accompanying drawing 5; Lid 4 is to be provided with the second major arc limit 43 of band string and the circular cover of bending structure 41; Bending structure 41 is two circumferential edges that are symmetricly set on lid 4, and the first major arc limit on the second major arc limit 43 and the pedestal 5 cooperates for complementary band string is circular.

Consult accompanying drawing 6, lid 4 and pedestal 5 are before assembling, and the bending structure 41 of lid 4 is a rugosity; During assembling with the folding pressing of bending structure 41; Expansion after the plastic deformation of lid 4 dependence bending structures 41 gets in the groove 51, and the bending structure 41 of pressing is pegged graft with groove 51, and lid 4 is fixedly installed on the pedestal 5; Realization lid 4 is fixedly connected with pedestal 5; The first major arc limit 53 on the second major arc limit 43 on the lid 4 and the pedestal 5 cooperates for complementary band string is circular, and the direction of distinguishable lid 4 in the automatic production process can prevent that lid 4 from adorning anti-assembly quality problem generation.
