Description

A kind of compressor electric accessories modular construction

Technical field

The utility model relates to a kind of modular construction, particularly relates to the modular construction of a kind of compressor start device, protector and operation electric capacity.

Background technique

On freezer compressor, be equipped with a plurality of accessories, its installation process needs inserted terminals, link, the operation of also need to manage line, the multisteps such as compressor shroud being installed.For to compressor, assembling manages better, simplify its assembly process, need to be to comprising that the part of starter, protector and operation electric capacity carries out modular construction processing.

As Figure 1-3; it is the assembling schematic diagram of compressor non-modularization structure in prior art; comprise the compressor shroud 102 that is arranged on compressor casing 101 sides; be contained in respectively top cover 103 and the operation electric capacity 104 of compressor shroud 102 both sides; on compressor bracket, protector 105 and starter 106 be housed in compressor shroud 102; in compressor shroud 102, the terminal base 107 of linking route is housed in top cover 103; the connecting line of protector 105 and starter 106 is connected with terminal base 107 is inner, and terminal base 107 outer ends connect outside refrigerator rat tail 108.

The compressor shroud of this kind of non-modularization structure and two devices, protector and starter, without being fixedly connected with relation, cause assembly process process poor each other, and three must install one by one step by step, and manufacturing efficiency is lower; Secondly, as shown in Figure 3, compressor shroud volume is larger, has blocked the assembly space of compressor bracket positioning hole 109 and assembling bolt, refills compressor shroud after must assembling in advance compressor, causes two devices and compressor shroud to realize pre-assembled, reduces manufacturing efficiency; Again, between components and parts, need to arrange many and connect electric wire, cause the expensive input of needs.

As shown in Fig. 4-11, it is the assembling schematic diagram of compressor electric accessories modular construction in prior art, the matrix 201 that comprises bottom, be contained in the enclosure 202 on matrix 201, the enclosure 202 is provided with positioning cylinder 203, also have dismountable electric capacity 204, electric capacity 204 is provided with trepanning and is placed on positioning cylinder 203; Also have protector 205 to be loaded in the cavity of matrix 201 bottoms, and by the snap fit 206 being arranged on matrix 201, be connected and fixed between the two; Protector power connector end 207 on protector 205 protrudes from outside the power supply terminal hole 208 on the enclosure 202 through matrix 201; Starter chip 209 is also equipped with in matrix 201 inside, with starter power connector end 210 outside the power supply terminal hole 208 protruding from the enclosure 202, connect sleeve 211 with the electric capacity that is connected electric capacity 204, the splicing ear on electric capacity 204 inserts electric capacity through the capacitor terminal hole 212 on the enclosure 202 and connects in sleeve 211; Protector power connector end 207 protruding from outside power supply terminal hole 208 is connected external power cord 213 with starter power connector end 210; The bottom of matrix 201 is also provided with 214, three jack 214 correspondences of three jacks and is placed on three sealed wiring posts 215 on compressor; On the shell both sides of the enclosure 202, be also provided with fixedly snap fit 216, the fixation holes 217 that compressor bracket is provided with fixedly snap fit 216 is interlocked, fixedly snap fit 216 interlocks to merge with fixation holes 217 whole module is fixed on compressor bracket.

This kind of modular construction, do not have can overlay module surface shell, make electric wire, tenminal block between components and parts and components and parts exposed in the external world, and the hole of enclosure outer surface is communicated with inner, the deficiency that causes electrical protection and electrical shock protection performance, within extraneous moisture, foreign matter, dust etc. are easily invaded module, long-term use meeting impacts the operation of equipment; Secondly, it is fixing that being connected between components and parts, between components and parts and external power cord is pushing against of contact, function does not interfix between power line and shell yet, in use, easily because power line is stressed, directly tear protector and starter, cause very high security risk, can not reach the safe design standard of national requirements; Again, the weight of operation electric capacity is large, installation position sets high, and power line from great, center is outer, makes the sealed wiring post being connected with module need to bear larger radial effect power, easily cause module to come off from sealed wiring post, or the stressed damage of sealed wiring post; Also have, if be fastened by snap fit between the enclosure and compressor bracket, and jack on matrix needs to fix with sealed wiring post, meet the connection positioning precision that these two means of fixation needs are higher simultaneously, make the adjustable of module position very low, cause production technology and precision requirement very high, and while installing easily because components and parts dislocation or not enough being difficult to of precision install, and cause the distortion of sealed wiring post even to damage.

Summary of the invention

The technical problems to be solved in the utility model is to provide the modular construction of a kind of compressor start device, protector and operation electric capacity, to realize the prepackage of starter, protector and operation electric capacity, and safer, stable, meet the requirement of safe design standard.

Compressor electric accessories modular construction described in the utility model, comprises the module box body being fixed on compressor bracket, and starter and protector are equipped with in the inside of module box body, and operation electric capacity is equipped with in the external stability of module box body; Described starter comprises the starter box body with holding cavity, with the starter lid from upper end capping starter box body, starter box body is fixedly mounted in module box body, on starter box body, chip cartridges is housed, power supply terminal and capacitor terminal are equipped with respectively in the both sides of chip cartridges, one end of power supply terminal and capacitor terminal is connected respectively the two poles of the earth of moving electric capacity, the other end of power supply terminal connects external power cord, starter chip is also equipped with in the inside of chip cartridges, and the two poles of the earth of starter chip connect respectively power supply terminal and capacitor terminal; Described protector is arranged on one end of starter box body, and which is provided with the splicing ear that connects external power cord.

Compressor electric accessories modular construction described in the utility model, within protector and starter are fixedly installed on module box body, and operation electric capacity to be fixed on modular cartridge external, jointly formed a modular construction, when chiller plant assembles, whole module can be directly installed on compressor, can complete the installment work of protector, starter and operation electric capacity; Can effectively reduce equipment volume, be more convenient to install and technology arrangement simultaneously; Protector, starter and operation electric capacity that modularization can realize under production line are pre-assembled, thereby reduce installation time required on production line, enhance productivity; Modular construction can also reduce the use amount that connects electric wire and splicing ear, and the use amount of the required screw of Assembly part, has greatly reduced cost of production; And the module box body that covers monnolithic case is coated within it by protector and starter, form effective monolithic case, sufficient electrical protection and electrocution-proof protection function is provided, and within extraneous dust foreign matter module more difficult to get access, has better safety in utilization and stability; It is inner that protector and starter are arranged on module box body, and operation electric capacity is fixed on modular cartridge external body, and its compact structure, simple is easy to realize.
