20090053082 | Electric Motor-Driven Compressor - An electric motor-driven compressor having a connector structure comprising a terminal connecting portion and a casing, the terminal connecting portion being provided with a hole for inserting an external terminal for power supply to an electric motor for driving a compression mechanism incorporated in a compressor housing, the casing covering the terminal connecting portion. In the electric motor-driven compressor, a collar is provided between a core wire and a covering material of a cable, at least a position corresponding to a sealing material provided at the cable inserting portion of the casing. The clearance between the cable and the sealing material can be prevented from increasing even when the cable is increased in temperature during power supply or when the cable is arranged in a bent fashion, and good sealing performance in the casing of the connector can be achieved, thereby enhancing reliability and durability of the electric motor-driven compressor. | 02-26-2009 |
20090257894 | ENHANCED AXIAL AIR MOVER SYSTEM CORD RETAINER - Implementations of an enhanced axial air mover system address various issues such as drying performance, transportability, storage, use, and assembly. Some implementations include ergonomic positioning of a carrying handle relative to positioning of a fan-assembly to make the system easier to carry. Enclosures with variable diameter profiles increase air flow performance. A floor edge allows for flush positioning of the air mover's outlet to improve flow of air. Various supports and engagement members allow for horizontal and/or vertical engagement of a plurality of the air movers for storage or increased air moving capacity for a given application. An alignment guide assists with positioning of the air mover with respect to a room wall to enhance air flow within the room. A cord retaining system provides an enhanced approach for securing the air mover's electrical cord. Grill guards have slotted ends to assist with assembly of the air mover. | 10-15-2009 |
20100178180 | Fuel supply device - A male terminal is provided in a terminal hole formed in a flange unit. A female terminal and a grommet having a sealing portion to be fitted into the terminal hole are provided to a harness. A distance from an end of the sealing portion to a fore-end of the female terminal is set smaller than a distance from a fore-end of the male terminal to an opening of the terminal hole. With such setting, the grommet is retained in the terminal hole even if the female terminal is disconnected from the male terminal, thereby ensuring support of the female terminal. Moreover, a stopper is attached so as to cover the terminal hole to prevent the grommet from slipping out of the terminal hole. | 07-15-2010 |
20100247353 | TERMINAL DEVICE FOR ELECTRIC COMPRESSOR - A terminal device for an electric compressor has a partition wall and a terminal member for supplying electricity to an electric motor for driving a compression mechanism. The partition wall is located between an electric motor-storing section, which stores the electric motor and in which lubricating oil-containing fluid to be compressed is present, and a circuit section for supplying electricity to the electric motor. The terminal member extends through the partition wall in a sealed and insulated manner. The terminal member is constructed as a steel bolt-like member, and an end of a lead wire for supplying electricity to the electric motor is directly connected by caulking to the end of the terminal member at the electric motor-storing section side. The terminal device can exhibit high insulation performance even if polyalkylene glycol-based oil is used as lubricating oil contained in fluid to be compressed. Further, the terminal device has a simple structure not requiring a cluster, can ensure high insulation performance, and can be constructed at low cost. | 09-30-2010 |
20100290938 | HERMETIC ELECTRICAL FEEDTHROUGH ASSEMBLY FOR A COMPRESSOR AND METHOD FOR MAKING THE SAME - An electrical feedthrough assembly for providing connection to components of a compressor. The electrical feedthrough assembly includes a housing having an inner surface defining a channel. A sealed wire assembly is provided in the channel. The sealed wire assembly includes a body having an outer surface defining a groove and a plurality of wires sealingly passing through the body. An o-ring fits in the groove to provide a hermetic seal between the body and the inner surface of the housing. | 11-18-2010 |
20100303650 | CURRENT LEADTHROUGH FOR A VACUUM PUMP - The vacuum pump comprises a casing ( | 12-02-2010 |
20100316514 | Heat-Dissipating Fan - A heat-dissipating fan includes a housing having a peripheral wall defining a compartment receiving a shaft seat. The peripheral wall includes a wire-guiding slot in communication with the compartment. A base is coupled to the housing and includes a coil unit and a connection port electrically connected to the coil unit. The connection port faces the wire-guiding slot. A power line includes a first end connected to the connection port and a second end extending through the wire-guiding slot. An impeller includes a hub, a shaft mounted to the hub and coupled to the shaft seat, and a permanent magnet mounted to the hub. The permanent magnet faces the coil unit. The connection port is located on a reference line passing through the shaft seat and the wire-guiding slot. A distance between the connection port and the wire-guiding slot is shortened to enhance assembling convenience of the power line. | 12-16-2010 |

20110158833 | ELECTRIC COMPRESSOR - An electric compressor is provided with a hermetic terminal wherein the number of components and the number of steps and amount of time required for assembling the hermetic terminal and for machining the components are reduced, to thereby improve production efficiency. The hermetic terminal ( | 06-30-2011 |
20120014822 | PRESSURE MITIGATING DIELECTRIC DEBRIS SEAL FOR A POTHEAD INTERFACE - A connector for connecting electrical power to a well pump motor has cable and motor connector portions that mate with each other in a connected position. The connector portions have insulating members, each of which has a number of passages and an end face. Electrical contact members are mounted in each of the passages. Contact members in the cable connector portion protrude past the end face of the insulating member. A debris seal insulates the electrical contact members in the cable connector and includes expansion slots so that when the material of the debris seal thermally expands, the expansion slots contract in response to the expansion without the debris seal impinging against either connector. | 01-19-2012 |
20120183420 | INVERTER-INTEGRATED ELECTRIC COMPRESSOR - An inverter-integrated electric compressor comprising a compressing mechanism portion which sucks, compresses and discharges fluid, a motor which drives the compressing mechanism portion, a body casing in which the motor is incorporated, the body casing being hermetically closed, a suction passage formed in one of ends of the body casing, and an inverter case in which an inverter for driving the motor is incorporated. At least a portion of the inverter case is closely brought into contact with and fixed to, in its axial direction, the body casing in which the suction passage is formed. | 07-19-2012 |

20130183177 | Tubing Encased Motor Lead - A system and methodology facilitates the supply of electrical power in a variety of harsh environments. The technique may utilize an electrical power cable having an insulator located around an electrical conductor. The insulator and the electrical conductor are positioned within a metallic tube. In a variety of applications, the metallic tube enables construction of the electrical power cable without an armor layer. A jacket is disposed between the insulator and the metallic tube and is designed to compensate for differences in thermal expansion between the materials. The jacket may be formed with gas pockets distributed therein to compensate for a different level of thermal expansion of the jacket relative to, for example, the metallic tube. | 07-18-2013 |
