The motherboard of the electronic device is provided at a position corresponding to the pogo pin connector with at least one metal contact, and the pogo pin connector is electrically connected to the metal contact. With the above fan frame electrical connector structure, it is possible to realize automated assembling of the fan to the electronic device motherboard.

An assembly for manually rotating a rotor includes a housing enclosing a first shaft and a second shaft accessible through an exterior wall of the housing. The first shaft extends from a first end rotationally coupled to the rotor to a second end selectively engageable with the second shaft. The second shaft includes a thrust plate extending from and rotatable with the second shaft. A spring disposed between the thrust plate and the housing biases the second shaft towards the exterior wall of the housing.

A passive flow modulation device for a machine defining an axial direction and a radial direction, the passive flow modulation device including: a first ring with a first coefficient of thermal expansion; a second ring disposed coaxially with the first ring and positioned at least partially inward of the first ring along the radial direction, spaced from the first ring along the axial direction, or both, the first ring, the second ring, or both defining at least in part one or more passages, the second ring with a second coefficient of thermal expansion that is less than the first coefficient of thermal expansion to passively modulate a size of the one or more passages during operation.

A turbocharger includes a variable nozzle disposed between a turbine housing and a bearing housing and a spring having an annular shape. The spring is disposed between the variable nozzle and the bearing housing, and is configured to generate a biasing force that biases the variable nozzle away from the bearing housing to widen a spacing between the variable nozzle and the bearing housing in a rotation axis direction. The spring includes an outer peripheral portion that applies the biasing force to the variable nozzle and an inner peripheral portion that comes into contact with the bearing housing. The outer peripheral portion of the spring is located further away from the turbine housing than the inner peripheral portion of the spring in the rotation axis direction.

A hidden fan and a fan lamp are disclosed. The hidden fan includes a turntable assembly and a plurality of fan blade assemblies arranged at the turntable assembly, the turntable assembly has a turntable and a limit wheel configured to rotate relative to the turntable, the turntable has a plurality of fan blade fixing portions, and the plurality of fan blade fixing portions are annularly arranged around a center of the turntable, at least one of the fan blade assemblies has a fan blade and a return elastic component, the fan blade has a fixed portion and a linkage portion arranged at a side of the fixed portion, the fixed portion is arranged at the corresponding fan blade fixing portion, the linkage portion is connected with the limit wheel.

A method for assembling a plug assembly for plugging one or more ports of a gas turbine engine including that a first arm is inserted into a sheath through-passage of a sheath. The method includes a second arm is inserted into the sheath through-passage of the sheath. The method further includes a separating mechanism is inserted into the sheath through-passage between the first arm and the second arm, a biasing mechanism is installed, and a top housing is slid over the biasing mechanism such that the biasing mechanism is located in a cavity defined within the top housing. The biasing mechanism being configured to apply a force to the first arm and the second arm when the biasing mechanism is located in the cavity. The method may also include that the top housing is secured together with the sheath.

A seal assembly adapted for use with a gas turbine engine includes a runner, a seal, and a compliant holder. The runner extends circumferentially about an axis and the compliant holder. The compliant holder engages the runner and is configured to support the runner radially relative to the axis. The seal extends circumferentially around the runner to block fluid flow through the seal assembly.

A bearing assembly for a turbo-engine with a bearing and parts of a bearing temperature detecting device. The bearing includes a main body having a thermoplastic bearing layer. A space is defined in the interior of the main body and of the thermoplastic bearing layer for accommodating parts of the bearing temperature detecting device. The space has a through hole having a first opening in the thermoplastic bearing layer and a second opening located in the main body. The parts include a temperature conducting element, a temperature sensor, and a securing fixture that attaches the temperature conducting element. The first opening of the through hole has a chamfer and the first end of temperature conducting element has a head which is correspondingly shaped to the chamfer in a form fitting manner. The center-axis of the temperature sensor extends transversely to the center-axis of the temperature conducting element.
