Definitions

  • the present invention refers to a protection and startup integrated combo for airtight refrigeration compressor which may accommodate in a sole product, different functions such as: cable press, fastening base (fence), fence cover, among others.
  • the present solution provides a system for fitting the combo to the airtight compressor housing, which is simple and effective compared with the previous techniques.
  • Protection and startup combo is a product performing functions of startup relay and overload protection in sole assembly.
  • Combos of the prior art techniques present the following disadvantages: a) extended time of installation for the cover with terminals, as it requires that the protection and startup components are connected via cable; b) they do not allow to fasten connection cables directly to the combo through cable press, as it is not firmly anchored to the compressor and would not be approved in a 100N cable traction test (the product would be drawn out from the airtight terminal, as required by IEC standard); c) they require a protection cover throughout the assembly (fence, airtight terminal and electrical components) to prevent electric component and connections thereof from wetting, thereby avoiding short circuit or electrical shock; d) extended number of discrete components; cover (with or without terminal blocks), overload protector, startup relay, cable press (1 or 2), cable press screws (1 or 2); making the mounting and component logistics more complicated and costly; e) require fastening plate (fence) welded to the compressor holding in order to allow anchorage of cable press and cover.
  • the present solution provides a complete and integral combo, unlike solutions typically provided separately, usually by the compressor's manufacturer.
  • the use of such solutions may be either partial or total.
  • the present invention offers a technological solution for protection and startup combo for airtight compressor, compared with the previous techniques, providing a complete and integral product, unlike previous solutions which typically are provided separately, in general by the compressor's manufacturer.
  • This invention has for object to propose a protection and startup integrated combo for airtight refrigeration compressor, which may accommodate in a sole product, different functions such as: cable press, fastening base (fence), fence cover, among others.
  • a protection and startup combo for airtight refrigeration compressor comprising at least one motor startup device and at least one motor overload protection device, the motor startup device being associated with the overload protection device, the combo comprising at least one cable press element or at least one fastening base, or at least a cover, or further the combination thereof, so as to form an integrated part associated, in the manner of fitting, with at least one airtight compressor feed terminal.
  • Figure 1 - represents a perspective view of the integral combo under the present invention, in a first embodiment
  • Figure 2 - represents a perspective view of the integral combo, under the present invention, in a second embodiment
  • Figure 3 - represents a perspective view of the integral combo under the present invention, in a third embodiment
  • Figure 4 - represents a second perspective view of the integral combo under the present invention, in a fourth embodiment
  • Figure 5 - represents a perspective view of the combo now proposed, highlighting the fit thereof into the compressor housing
  • Figure 6 - represents a perspective view of the combo, highlighting the fit terminals of the combo herein proposed.
  • the protection and startup combo for airtight refrigeration compressor 1 comprises at least one motor startup device 2 and at least one motor overload protection device 3, the motor startup device 2 being associated with the overload protection device 3.
  • the present protection and startup combo comprises at least one cable press element 15, or at least one fastening base 25 or at least one cover 35, or further the combination thereof, as illustrated in figuresi to 3, so as to form an integrated part associated, in a fitting manner, with at least one feed terminal of the airtight compressor.
  • figures 4 and 5 show that the fastening base 25 is provided with a lock ring 40 which may provide mechanical coupling with a fastening flange 50 of the compressor.
  • Figure 4 shows that the lock ring 40 is provided with a sealing ring 8.
  • Said fastening base 25 provides mechanical coupling to the fastening flange 50 of the compressor through rotation connection terminals 9 arranged in the fastening base 25.
  • Figure 6 shows details of the rotation terminals herein proposed.
  • Rotation connection terminals 9 are associated with at least one feed terminal of the airtight compressor through a first fitting movement and a second fitting movement in a direction substantially angular regarding the first movement.
  • Rotation connection terminals 9 have been created specifically to make feasible the connection of combo with the compressor through the compressor fastening flange 50. This type of terminal allows to fit into the pins of the rotation airtight terminal, while the conventional connectors (pin- connectors) serve only for connection in axial direction regarding fusite pins.
  • Rotation connection terminals 9 may be provided with rotation terminal extensions, in an optional embodiment. Said terminal extension serves to allow a direct connection of protectors and relays in their original configurations to the rotation connection terminals.
  • the present combo comprises at least one electrical connector platform, either lateral or frontal.
  • integrated cable presses usually they are integrated in the connection box, fence cover or even as an independent part specifically intended for that purpose, which are fastened to the fence.
  • the proposal is to cause the cable press function to be an integral part of the combo;
  • integrated fence or fastening base it is always an integral part of the compressor and serves as a fastening base for combos, covers, cable press or startup and speed capacitors. The proposal is to integrate it to the combo;
  • integrated fence cover usually it is manufactured in plastic and overlapped to the fence to protect the protector and startup relay, as well as connections thereof.
  • the proposal is to integrate it to combo, overlapped to the integrated fence.
  • the present invention offers as advantages, compared with previous techniques, the following characteristics: a) simplification and cost reduction for mounting of electrical components and connections to the compressor; b) cost reduction through reduction in the number of items, inventory and logistics simplification by manufacturers of compressors and refrigerators; c) possibility of fastening cables directly to combo, as the same, with the integrated fence, begins to be firmly anchored to the compressor; d) no additional cover, as the new assembly begins to provide all mechanical, electrical and sealing protections required; and e) cost reduction by elimination of the traditional steel fence welded to compressor housing.
  • fastening flange this alternative consists in fastening a welded steel flange to the compressor, around airtight compressors (fusite), acting as a socket for combo fastening.
  • the combo in turn, is provided with a structure which fits into the fastening flange;
  • lock ring this alternative for fastening consists in a steel ring fastened to the combo fence, around connection terminals. This ring is fitted under pressure to the metallic structure of the compressor airtight terminals (fusite), thus preventing the combo to be removed from the compressor; 4. sealing ring (o-ring) in "fusite”: the use of a sealing ring between the airtight terminal structure (fusite) and the combo assures the sealing of the system, thus preventing humidity to enter the region of fusite. In the conventional systems, this protection is provided by the fence;
  • cable press there are several alternatives for anchorage of cable press to combo: a. integrated to the cover: the cable press can be an integral part of the combo cover. b. integrated to combo base: in this case, cable press would be an integral part of the combo. c. integrated to the combo base and anchored to the conventional fence: this cable press alternative is used in combo versions which do not use integrated fence and therefore the conventional fence is present.
