A lever assembly for coupling a computer module to a chassis includes a base lever, a locking tab, and a flexible element positioned between the base lever and the locking tab. The base lever is rotatably coupled to the computer module. The base lever is rotatable between an installed position and an opened position. The locking tab is rotatably coupled to the computer module for engaging a locking surface on the chassis when in a locked position. The locking tab is rotatable between the locked position and an unlocked position. The flexible element is configured to bias the locking tab into the locked position when the base lever is in the installed position. Rotation of the base lever to the opened position induces rotation of the locking tab to the unlocked position.

A locking mechanism for applying in a computer case is disclosed. The locking mechanism comprises: an actuating unit and a locking member. The actuating unit is pivotally connected to one of two vertically-disposed side plates of the computer case by one end thereof, and comprises a pivot member and a latching member. In the present invention, the actuating unit rotates along a first direction parallel to the vertically-disposed side plate, so as to decrease space required by operating the locking mechanism. Such that the locking mechanism brought advantages of great space-saving, high capacity and low cost of production cost.

A processing assembly including cage, partition, two sub-cages, two motherboards, two switch boards and at least one bridge board. Partition is disposed in cage so as to divide inner space of cage into first accommodation space and second accommodation space. Two sub-cages are respectively disposed in first accommodation space and second accommodation space. Two motherboards are respectively disposed on two sub-cages. Two motherboards each include a plate and a plurality of processing units disposed on the plate. Two switch boards are respectively disposed on two sub-cages and respectively electrically connected to two motherboards. Bridge board is electrically connected to two motherboards. One of two motherboards is located between one of two switch boards and bridge board, and another one of two motherboards is located between another one of two switch boards and bridge board.

A locking device includes a housing, a first linking member, a second linking member, a push-pull member, and a stopper. The push-pull member defines a first sliding groove. A first end portion of the first linking member is slidably received in the first sliding groove, and a second end portion of the first linking member is rotationally fixed on the housing. The housing defines a second sliding groove. The stopper is slidably received in the second sliding groove. A second end portion of the second linking member is rotationally mounted on the first linking member. The first end portion of the first linking member is driven by the push-pull member to move along the first sliding groove, which drives the second linking member to rotate, which drives the stopper to move along the second sliding groove.

The invention relates to a method and a modular holding and exchanging system (1) for medium or high voltage converters, preferably a modular multilevel converter, comprising a rack (2) for receiving at least two power modules (3) arranged on top of one another in receiving spaces (4), wherein the rack (2) has at least two pairs of vertical standing elements (5) and at least two carrier elements (6) connecting the vertical standing elements (5) in a longitudinal direction (10) of the rack (2) in a horizontal support plane (9), a lifting tool (7) that can be coupled with the rack (2), which lifting tool (7) comprises at least one, preferably at least two, rolling bodies (19) that can be adjusted between a rest position (13) and a support and/or service position (14) for temporarily raising and/or moving a power module (4), wherein the power modules (4) have support surfaces (16) projecting in a transverse direction (11) with respect to a housing width (15) for being supported on the carrier elements (6), and the carrier elements (6) have an upper side (17) provided for at least parts of the support surface (16) of the respective power module (4) to rest on, and are configured as a profile element such that every carrier element (6) has at least one, preferably at least two passages (18), each, that are spaced apart from one another in the longitudinal direction (10), for at least one rolling body (19) to pass through in the service position (14) of the lifting tool (7), and wherein the lifting tool (7) comprises a longitudinally extended profile body (21), preferably a hollow body, configured so as to be insertable into the profile element of the carrier element (6) in the rest position (13), in which profile body (21) a lever device (20) is formed for adjusting the at least one rolling body (19), preferably of the at least two rolling bodies (19), which are spaced apart from one another in the longitudinal direction (10), from the rest position (13) into the service position (14).

A locking device includes a housing, a first linking member, a second linking member, a push-pull member, and a stopper. The push-pull member defines a first sliding groove. A first end portion of the first linking member is slidably received in the first sliding groove, and a second end portion of the first linking member is rotationally fixed on the housing. The housing defines a second sliding groove. The stopper is slidably received in the second sliding groove.
