Abstract: An electrical connector for making electrical contact with at least one lead of an electronic device. The connector includes a mounting flange portion and a connector housing portion. The connector also includes at least one conductor having a pin end and a terminal end, wherein the terminal end includes a lead opening that receives the lead and a fastener hole oriented substantially transverse to the lead opening. A fastening element is used to engage the fastener hole and contacts the lead to form electrical contact between the conductor and the lead. The connector further includes a conductor carrier that extends through the connector housing and mounting flange. The conductor carrier includes a base portion and at least one extended portion that extends from the base portion to form a staggered arrangement. The base and extended portions each include a plurality of channels wherein each channel includes a conductor.

Abstract: A fluid compression system is disclosed having a hermetically-sealed housing with at least a motor and a compressor arranged therein. The motor may drive both the compressor and a blower device coupled to the housing or otherwise arranged within the housing and configured to circulate a cooling gas throughout the housing and thereby cool the motor and accompanying radial bearings. The blower device circulates the cooling gas through a closed-loop circuit which may include a heat exchanger and gas conditioning skid. Buffer seals may be used to seal the shaft on both sides of the compressor so as to prevent the migration of liquid and solid contaminants into the closed-loop cooling circuit.

Abstract: A system and method for rapid pressurization of a motor compartment and cooling system during a shutdown, a surge, and/or other situations in which the suction pressure significantly varies. A motor/compressor arrangement includes a seal gas system fluidly communicating with the motor compartment via a motor pressurization line, with the outlet of the compressor, and with a shaft seal. A motor pressurization valve is coupled to the motor pressurization line and a controller is configured to open the motor pressurization valve at start-up of the motor-compressor to supply seal gas to the motor compartment and to pressurize the motor compartment when a difference between the seal gas supply pressure and the suction pressure is indicative of the seal gas supply pressure being insufficient.
