A pull-out aiding device is configured for mounting on an object, in which a corresponding apparatus is mounted. The pull-out aiding device includes a pulling member and a handle member. The pulling member includes a first pivot section and an abutting section for abutting against the corresponding apparatus to move the latter forward. The handle member includes a second pivot section and an operating section. The second pivot section is pivotally connected to the first pivot section, such that the handle member is turnable about the second pivot section relative to the pulling member and brings the latter to move forward.

A stability device comprising a carrier having a first socket and a second socket; a first circuit board inserted into the first socket; a second circuit board inserted into the second socket, wherein an inside surface of the second circuit board is facing an inside surface of the first circuit board; a center structure positioned between the inside surface of the first circuit board and the inside surface of the second circuit board, wherein the center structure is fixed to the carrier via a stability bar fixed to the carrier; a spring loaded outer structure at least partially surrounding an outside surface of the first circuit board and an outside surface of the second circuit board and to fix the center structure between the inside surface of the first circuit board and the inside surface of the second circuit board, wherein the center structure and outer structure dissipate heat.

A fixing apparatus for holding a circuit board in place includes a cover plate, a base for supporting the circuit board thereon, a connecting assembly for hinge-coupling a first end of the cover plate to the base, and a latching assembly for latching a second end of the cover plate to the base. The circuit board is held in place between the base and the cover plate.

In one example a latching system is disclosed. The latching system has a handle that moves along an axis of motion between three positions: a latched position, an unlatched position and an engaged position. The handle moves a retention clip from a locked position into an unlocked position when the handle moves from the unlatched position into the engaged position.

An electronic component unit of a wire harness includes a substrate on which an electronic component is mounted, a connector electrically connected to the substrate, and a connector fixing structure. The connector fixing structure includes a pair of notches that are provided facing each other on ends of the substrate in a long-side direction and that penetrate through the substrate in a plate thickness direction, a pair of press fitting plates that are provided on the connector and that are press-fitted into the respective notches, and a deformation acceptable space that is provided adjacent to each of both sides of the press fitting plates press-fitted into the respective notches in the long-side direction.

An ejector may be provided. The ejector may comprise a pawl, a trigger, and a handle. The pawl may be configured to rotate relative to a line card about a first axis. The pawl may comprise a pawl concavity. The trigger may be configured to rotate relative to the line card about a second axis. The trigger may comprise a trigger catch and a trigger lever. The trigger catch may be configured to engage the pawl concavity. The handle may be connected to the pawl and configured to rotate relative to the pawl about a third axis. The trigger catch may be configured to engage the pawl concavity to inhibit rotation of the pawl about the first axis. The trigger catch may be configured to disengage the pawl concavity and to allow rotation of the pawl about the first axis.

A dual connect switch module may include a first set of pluggable panel connectors on a first side of a substrate of the switch and a second set of pluggable panel connectors on an opposing second side of the substrate. The switch module further includes a switch Integrated Circuit (IC) mounted between the first side and the second side, where the switch IC is connected to the first set of pluggable panel connectors and to the second set of pluggable panel connectors. A cable can be used to connect at least one pluggable panel connector of the first set of pluggable panel connectors and/or of the second set of pluggable panel connectors with a port of an external network device. In some examples, the switch and substrate may further include a management module that manages one or more on-board functions of the switch module.

A latch assembly may include a support, a handle for rotatably coupling to one of the support and the housing via a first axis and rotatable between unlatched and latched positions relative to the support, and a catch arm rotatably coupled to the handle via a second axis and arranged such that as the handle is rotated from the unlatched to an intermediate position between the unlatched and latched positions, the catch arm is translated in an arc from a first position in which it is disengaged from a post to a second position in which a retention feature of the catch arm positions itself under and proximate to a ledge of the post, and as the handle is rotated from the intermediate to the latched position, the catch arm and the retention feature move in a linear direction from the second to a third position.

A control circuit board includes a signal output connector having an output terminal for outputting a control signal, a DC voltage input connector to which power generated by a power supply circuit board is input, and a power output connector including an output terminal for outputting the power. A drive circuit board includes a signal input connector having an input terminal for inputting a control signal, and a power input connector having an input terminal for inputting the power. The power supply circuit board includes a power output part for outputting power. The drive circuit board is held on the control circuit board in such a posture as to rise from a board surface of the control circuit board by connection between the signal input connector and the signal output connector, and connection between the power input connector and the power output connector.
