A retention-extraction device is provided for a removable card in a chassis. The device includes an actuation rod having a cam slot, the actuation rod configured to provide linear movement along the length of the actuation rod, and an extraction lever operatively connected to a proximal end of the actuation rod and pivotally secured to the chassis. The device also includes a bell crank with a cam follower that is configured to ride in the cam slot and a latch hook that pivots between an open and closed position based on the motion of the bell crank. The linear movement of the actuation rod causes the extraction lever to apply a force to a portion of the card and causes the latch hook to pivot to an open position to allow removal of the card.

A method for securing and removing modular elements employing latches is disclosed. A modular element may include a chassis body supporting electronic components. The body is in communication with a latch and a control member of the modular element. The modular element is removable from or secured to an enclosure using the latch. The latch may engage the enclosure and may remain engaged by being secured by interfacing with a catch of an arm of the control member. By connecting the arm to the control body with a living hinge, the living hinge may urge the catch into a detent of the latch to secure the latch and keep the modular element secured to the enclosure. The latch may be disengaged from the control member by applying a disengagement force to remove the catch from the detent. In this manner, the modular element is efficiently secured and removed from the enclosure.

A device for installing an elastic sealing ring on an electronic device includes a clamp module and a pressing module. The clamp module includes a sliding column defining two grooves, two linkage plates, and two pins secured on the bottom end of the linkage plates. The pressing module includes a bracket and a knockout plate. The linkage plates are rotatably installed on the bracket and the sliding column can slide relative to the bracket. The knockout plate can slide relative to the bracket, to install the sealing ring on an electronic device.

Modular elements employing latches with flexure bearings are disclosed. A modular element may include a chassis body supporting electronic components. The body is in communication with a latch and a control member of the modular element. The modular element is removable from or secured to an enclosure using the latch. The latch may engage the enclosure and may remain engaged by being secured by interfacing with a catch of an arm of the control member. By connecting the arm to the control body with a flexure bearing, the flexure bearing may urge the catch into a detent of the latch to secure the latch and keep the modular element secured to the enclosure. The latch may be disengaged from the control member by removing the catch from the detent. In this manner, the modular element is efficiently secured and removed from the enclosure.

A module placement apparatus is provided and includes alignment brackets and a module placement tool. The alignment brackets include first guidance features, define an interior and are disposable aside an array of contacts. The module placement tool is insertible into the interior in first and second stages and includes a frame, a module gripping element operably supported on the frame, second guidance features engageable with the first guidance features at a conclusion of the first stage to maintain a relative orientation of the array of contacts and the frame during the second stage, and a gimbaled handle coupled to the module gripping element to maintain the relative orientation during the first stage until at least first and second guidance feature engagement.

A tool for installation and removal of a connector of a gas-insulated switchgear termination includes a housing defining an operation chamber therein, a mounting assembly selectively disposed in the operation chamber of the housing and adapted for securely installing a sleeve member of a gas-insulated switchgear termination on a conical connector member of the gas-insulated switchgear termination or removing the sleeve member securely sleeved on the conical connector member from the conical connector member, an actuator assembly adapted for actuating motion of the mounting assembly, and a friction reducing assembly adapted for reducing friction and resistance occurring during the motion of the mounting assembly.

A SFP tool can include a tool body with an installer key slidingly engaged with the tool body and/or an extractor key slidingly engaged with the tool body. The installer key can include one or more port engagers at a distal end of the installer key to engage with one or more corresponding ports in a SFP for installing the SFP into a SFP slot in a networking device. To remove a SFP from a SFP slot of a networking device, a bail engager pivotally coupled to an extractor key at a distal end of the extractor key can be engage and unlock a bail on the SFP. The SFP can be removed by moving a extractor key handle away from the networking device and/or the pressure can be applied to the extractor key handle and the SFP tool can be pulled away from the networking device.

Certain embodiments of the invention may include systems and methods for providing stator bar shape tooling. According to an example embodiment of the invention, a method is provided for shaping an element. The method can include providing at least one constraining surface, wherein the at least one constraining surface is fabricated at least in part by selective laser sintering, and deforming an element with the at least one constraining surface to define at least an external shape of a formed element.
