Definitions

  • the present invention refers to a protection and startup modular combo for airtight refrigeration compressor, requiring a low number of tools to produce several combo configurations, compared with previous techniques, as well as the use of simpler tools and the consequent cost reduction for development of such configurations.
  • Background of the invention Protection and startup combo is a product performing functions of startup relay and overload protection in sole assembly.
  • combos are constructed in such a way that each function is an integral part of combo without being dissociated.
  • the present invention offers a technological solution for protection and startup combo for airtight compressor, compared with previous techniques, thereby providing a system which makes use of a simpler and cost-effective tool.
  • This invention has for object to propose a protection and startup modular combo for airtight refrigeration compressor, requiring a low number of tools to produce several combo configurations compared with previous techniques, as well as the use of simpler tools and the consequent cost reduction for development of such configurations.
  • a protection and startup combo for airtight refrigeration compressor comprising at least one motor overload protection device, the motor startup device being associated, in the manner of fitting, with the overload protection device, the protection and startup combo being associable with at least one airtight compressor electrical feed terminal, the combo being associable, in the manner of fitting, with at least one electrical connector platform, the combo being associable with at least one cable press device.
  • Figure 1 - represents a perspective view of parts forming a first embodiment of the modular combo under the present invention
  • Figure 2 - represents a perspective view of the modular combo, object of the present invention
  • Figure 3 - represents a perspective view of a second embodiment of the modular combo under the present invention.
  • Figure 4 - represents a second perspective view of the second embodiment of the modular combo under the present invention.
  • Figure 5 - represents a perspective view of parts comprising the modular combo in its second embodiment under the present invention
  • Figure 6 - represents a perspective view forming the modular combo under the present invention, in a third embodiment.
  • FIGS 1 to 6 show possible embodiments for the modular combo herein proposed.
  • the protection and startup combo for airtight compressor 1 under the present invention comprises at least one motor startup device 2 and at least one motor overload protection device 3.
  • the motor startup device 2 (startup relay) is associated in the manner of fitting, with the overload protection device 3.
  • the protection and startup combo 1 is associable with at least one electrical feed terminal of the airtight compressor, the same being associable in the manner of fitting, with at least one platform of electrical connectors.
  • Combo 1 is associable, in the manner of fitting, with at least one cable press device 30, as illustrated in detail in Figure 5.
  • Combo 1 is associable with at least one platform of side electrical connectors 10.
  • Combo is associable with at least one platform of frontal electrical connectors 20, the same being further associable, in the manner of fitting, with a support base 40.
  • the support base 40 is associated with a housing of an airtight compressor.
  • the present combo 1 may further be associable, in the manner of fitting, with a cover 50, as illustrated in details in Figure 6.
  • the combo can be formed through the combination of several modules, as illustrated below: a) basic protection and startup combo (several models of protection and startup can be used (4TM, 4MP, %"MP, etc.); b) platform of connectors with frontal access; c) platforms of connectors with side access; d) cable press; e) fence; and f) cover.
  • the present combo offers as advantages, compared with the previous techniques, the following characteristics: a) lower number of tools to produce several combo configurations; b) simpler tools to produce more complex combos; c) simpler discrete components allow application of over-molding techniques to obtain cost reduction; d) enables a wide range of configurations at a lower cost; e) cost reduction of inventory due to a lower number of items and lower complexity of discrete items.
  • the combo herein proposed, is, in the manner of a slide, associable with platforms of side electrical connectors 10 or platforms of frontal electrical connectors 20.
