Description
Technical field
The invention belongs to technical field of refrigeration compressors, be specifically related to a kind of protection mechanism of terminal box of refrigeration compressor
Background technique
such as industry the reason of knowledge; The refrigeration compressor that uses on the electrical equipment such as refrigerator, refrigerator-freezer, Food Freezing and Cold Storage show cabinet is owing to need install the annex such as starter, overload protective device outside body; And be connected to power supply by wiring; Therefore on compressor, be equipped with a terminal box usually; The assembling of guaranteeing system by this terminal box is neat, and can play the influence that makes aforesaid annex and wiring avoid receiving external environment condition, to ensure the functional reliability of compressor.
are no lack of the technology contents that is seen in about the terminal box of freezer compressor in disclosed Chinese patent document; A kind of freezer compressor that typical as practical novel license notification number CN201204415Y recommends is used terminal box, and this patent scheme is in order to make external power supply and reliably to be connected with compressor and proposing.A kind of freezer compressor terminal box that notice of authorization CN2903821Y provides, this scheme come off to the lead generation of avoiding being connected with compressor equally or bad connection proposes.A kind of rotor-type compressor that application for a patent for invention publication No. CN101924335A introduces has simple in structure with symmetrical box-base-type hasp terminal box and uses the strong point of raising electric efficiency with reducing the harmonic wave in the motor operating current.A kind of freezer compressor terminal box of touching that CN201779923U discloses, this patent scheme has achievement for fixing various lead-in wires easily.
The common feature of the terminal box of the freezer compressor in the prior art that give an example above being not limited to
is all to himself structure; Though its prominent point is respectively arranged or claims technique effect; But exist Security to be short of and to lose the logical fraud of insulating properties at least; Because in the practical work process of household electric appliance compressor, run into more extreme abnormal conditions sometimes, like thunderbolt, supply voltage is too high, ambient temperature is too high and/or unusual lost efficacy etc. appears in electronic parts and components; At this moment situation on fire might appear in annex and the wiring system in the compressor electrical junction box; The little condition of a fire that produces in the terminal box tends to break through the lid and the box body of terminal box, and the condition of a fire is outwards spread, and causes that people do not hope the bigger fire that occurs.Although the probability of this situation is lower, and only under extreme case, just might occur, the not rarely seen report that this situation is arranged causes damage to the user in reality, produces totally unfavorable influence to production firm simultaneously.Be prone to cause the electric leakage accident in case appearance such as the connector assembly in the terminal box, electric wiring are unusual again.
In view of above-mentioned prior art, be necessary to improve, the applicant has done useful design for this reason, and under secrecy provision, proves practicable through experiment, and the technological scheme that will introduce below produces under this background
Summary of the invention
task of the present invention is to provide a kind of butted line box that helps to protect and use and avoid external environment condition to cause the influence of butted line box; Such as by thunderbolt, supply voltage is too high, ambient temperature is too high and/or the unusual situation that lost efficacy of electronic parts and components under help stoping the intensity of a fire to break through terminal box to the outside diffusion and spread and use and ensure safety, be of value to the protection mechanism of guaranteeing desirable insulation effect and using the terminal box of the refrigeration compressor that embodies safety.
task of the present invention is accomplished like this; A kind of protection mechanism of terminal box of refrigeration compressor; Described refrigeration compressor comprises a refrigeration compressor body, and this refrigeration compressor body comprises that one has the terminal box of cassette holder, and the protection mechanism of described terminal box comprises a flameproof enclosure; This flameproof enclosure cover is put outside described cassette holder, and fixes with cassette holder; One electric insulation cover, this electric insulation cover are combined on the inwall in flameproof enclosure chamber of flameproof enclosure.
in a concrete embodiment of the present invention, the shape of described electric insulation cover is corresponding to the shape of flameproof enclosure.
In another concrete embodiment of the present invention, the thickness of described electric insulation cover equates with the thickness of described flameproof enclosure
.
in another concrete embodiment of the present invention, the thickness of described electric insulation cover is than the thicker of described flameproof enclosure.
in another concrete embodiment of the present invention, the thickness of described electric insulation cover is than the thin thickness of described flameproof enclosure.
also have among the concrete embodiment of the present invention, and described flameproof enclosure is the metal flameproof enclosure, and the material of described electric insulation cover is plastics, rubber or bakelite.
are more of the present invention and among concrete embodiment; On described cassette holder, offer first screw hole; And on described flameproof enclosure and in position, offering second screw hole corresponding to first screw hole, second screw hole is fixed by the screw and first screw hole.
in of the present invention and then concrete embodiment, the shape ovalize of described second screw hole.
technological scheme provided by the invention has been owing to set up flameproof enclosure in a creative way outside terminal box, thereby can avoid external environment condition such as trifle in the world, steam, mouse and/or cockroach and domestic pets to cause the influence of butted line box; Meet with such as thunderbolt, supply voltage sudden change, ambient temperature raise suddenly and/or electronic parts and components unusual and when situation on fire occurring, play insulating effect by flameproof enclosure, avoid causing bigger fire because of fire spreading, help to ensure safety; Owing on the inwall in the flameproof enclosure chamber of flameproof enclosure, set up the electric insulation cover, thereby can avoid the accident that causes because of electric leakage, to guarantee safety.
Description of drawings
Fig. 1 is the embodiments of the invention structural drawing.
Embodiment
can be expressly understood technical spirit of the present invention and beneficial effect more for the auditor that the makes Patent Office especially public; The claimant general elaborates with embodiment's mode below; But the description to embodiment all is not the restriction to the present invention program, any according to the present invention design done only for pro forma but not substantial equivalent transformation all should be regarded as technological scheme category of the present invention.
