Description
Technical field
The present invention relates to a kind of modular construction, particularly relate to the modular construction of a kind of compressor start device, protector and operation electric capacity.
Background technique
Freezer compressor is equipped with multiple accessory, its installation process needs inserted terminals, link, also needs the operation carried out managing line, install the multisteps such as compressor shroud.For fitting into line pipe reason to compressor better, simplifying its assembly process, needing the part to comprising starter, protector and operation electric capacity to carry out modular construction process.
As Figure 1-3; it is the assembling schematic diagram of compressor non-modularization structure in prior art; comprise the compressor shroud 102 being arranged on compressor casing 101 side; be contained in the top cover 103 of compressor shroud 102 both sides respectively and run electric capacity 104; on compressor bracket, compressor shroud 102 is built with protector 105 and starter 106; in compressor shroud 102, top cover 103 is built with the terminal base 107 of linking route; protector 105 is connected with terminal base 107 the inner with the connecting line of starter 106, and terminal base 107 outer end then connects outside refrigerator rat tail 108.
The compressor shroud of this kind of non-modularization structure and two devices, i.e. protector and starter, each other without being fixedly connected with relation, cause assembly process process poor, three must install one by one step by step, and manufacturing efficiency is lower; Secondly, as shown in Figure 3, compressor shroud volume is comparatively large, has blocked the assembly space of compressor bracket positioning hole 109 and assembling bolt, has refilled compressor shroud, cause two devices and compressor shroud cannot realize pre-assembled after must assembling compressor in advance, reduces manufacturing efficiency; Again, need to arrange many between components and parts and connect electric wire, cause the input needing high cost.
As shown in Fig. 4-11, it is the assembling schematic diagram of compressor electric accessories modular construction in prior art, comprise the matrix 201 of 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 bottom, and be connected and fixed by the snap fit 206 be arranged on matrix 201 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 protruded from the enclosure 202, connect sleeve 211 with the electric capacity being 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 protruded 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 three jacks, 214, three jack 214 correspondences and is placed on three sealed wiring posts 215 on compressor; The shell both sides of the enclosure 202 are also provided with fixing snap fit 216, and compressor bracket is provided with the fixation holes 217 be interlocked with fixing snap fit 216, and fixing snap fit 216 interlocks to merge with fixation holes 217 and whole module is fixed on compressor bracket.
This kind of modular construction, not having can the shell on overlay module surface, make the electric wire between components and parts and components and parts, tenminal block exposed in the external world, and the hole of enclosure outer surface is communicated with inner, cause the deficiency of electrical protection and electrical shock protection performance, extraneous moisture, foreign matter, dust etc. easily invade within module, and Long-Time Service can impact the operation of equipment; Secondly, it is fixing that connection between components and parts, between components and parts and external power cord is pushing against of contact, do not interfix between power line and shell function yet, in use, easily directly tear protector and starter because power line is stressed, cause very high security risk, the safe design specification of national requirements can not be reached; Again, the weight running electric capacity is large, installation position sets high, and power line from great, center is outer, making needs to bear larger radial forces with the sealed wiring post of model calling, module is easily caused 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 the 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 be easily difficult to install because of components and parts dislocation or precision deficiency when installing, and cause the distortion of sealed wiring post even to damage.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of compressor start device, protector and runs the modular construction of electric capacity, to realize the prepackage of starter, protector and operation electric capacity, and safer, stable, meet the requirement of safe design specification.
Compressor electric accessories modular construction of the present invention, comprises the module box body be 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, starter box body is equipped with chip cartridges, the both sides of chip cartridges are equipped with power supply terminal and capacitor terminal respectively, power supply terminal and one end of capacitor terminal are connected the two poles of the earth running electric capacity respectively, 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 power supply terminal and capacitor terminal respectively; Described protector is arranged on one end of starter box body, and which is provided with the splicing ear connecting external power cord.
Compressor electric accessories modular construction of the present invention, protector and starter are fixedly installed within module box body, and running electric capacity, to be fixed on modular cartridge external, jointly constitute a modular construction, when chiller plant assembles, can whole module be directly installed on compressor, the installment work of protector, starter and operation electric capacity can be completed; Can equipment volume be effectively reduced simultaneously, more be convenient to install and technology arrangement; Protector, starter and operation electric capacity that modularization can realize under production line are pre-assembled, thus reduce installation time required on production line, enhance productivity; Modular construction can also reduce the use amount connecting electric wire and splicing ear, and the use amount of screw needed for Assembly part, significantly reduces cost of production; And the module box body covering monnolithic case by protector and starter within it coated, form effective monolithic case, sufficient electrical protection and electrocution-proof protection function are provided, and within the dust foreign matter module more difficult to get access in the external world, have better safety in utilization and stability; Protector and starter are arranged on module tray interior, run electric capacity and are fixed on modular cartridge external body, its compact structure, simple, are easy to realize.
