A carrier tray to allow rapid installment of additional modules or devices, without screws, into a computer includes a frame, two sliders, an elastic member, and a handle. A bracket of the frame has a unit cavity. The two sliders can slide along a first direction and the elastic member is compressible between the two sliders. The handle allows pushing and pulling of the tray along a second direction and is attached to the two sliders, the two sliders can move towards each other (to a first position) or apart (to a second position). The two sliders return to the unity cavity by pulling the handle from the first position to the second position along the second direction. Continued pulling of the handle in the second direction removes the carrier tray from the computer.

An electronic shelf label system includes a powered rail for holding electronic shelf labels. The front side of the rail includes a recess that is physically configured to receive a protrusion at the upper rear side of the shelf label. The shelf label further comprises a lower hook member for engaging with a lower edge of the rail. The rail may comprise two conductors for providing the labels with power and data for display on the label. Data and power may be provided via a controller and power module connected to the back of the rail.

What is provided is an attachment member that can be respectively attached to target members of different types, the member including a member main body, a first protrusion which is provided at an end portion of the member main body and is engageable with a first engaged part formed on a first target member, a second protrusion which is provided at the end portion of the member main body and is engageable with a second engaged part formed on a second target member, and an advancement and retraction mechanism which is configured to cause the second protrusion to advance and retract from the end portion of the member main body.

A display device includes: a module cover; a display panel which is positioned in front of the module cover, and is coupled to the module cover; a frame which surrounds a side surface of the module cover, the frame including a first frame adjacent to one side of the module cover and a second frame adjacent to the other side of the module cover opposite to the one side of the module cover; a bar which is positioned behind the module cover, extends long between the first frame and the second frame, and is coupled to the first frame and the second frame; and a mount which is positioned behind the module cover, adjacent to the one side of the module cover, and is coupled to the bar, wherein the mount is coupled to the first frame and the module cover.

A chassis for a storage device includes a chassis body and an installation frame slidably installed in the chassis body by using a sliding assembly. The installation frame is configured to slide out from two ends of the chassis body. The sliding assembly includes a first sliding rail, a second sliding rail, and a first limiting assembly. The first sliding rail is fastened to the chassis body, the second sliding rail is fastened to the installation frame, and the first sliding rail and the second sliding rail are slidably assembled. The first limiting assembly includes a first clamping part and a second clamping part that fit with each other. A first drive component drives the first clamping part to be clamped with the second clamping part, and a second drive component drives the first clamping part to be detached from the second clamping part.

A display device includes: a module cover; a display panel which is positioned in front of the module cover, and is coupled to the module cover; a frame which surrounds a side surface of the module cover, the frame including a first frame adjacent to one side of the module cover and a second frame adjacent to the other side of the module cover opposite to the one side of the module cover; a bar which is positioned behind the module cover, extends long between the first frame and the second frame, and is coupled to the first frame and the second frame; and a mount which is positioned behind the module cover, adjacent to the one side of the module cover, and is coupled to the bar, wherein the mount is coupled to the first frame and the module cover.

Disclosed is a universal jig for charging and discharging a secondary battery cell. The universal jig includes a cell zig assembly including: a cell receiving part for receiving the secondary battery cell thereon; and a zig for a positive electrode terminal and a zig for a negative electrode terminal disposed above the cell receiving part and in contact with a positive electrode terminal and a negative electrode terminal of the secondary battery cell to apply current thereto, respectively; and a zig rotation inducing assembly connected, via a rotation center shaft thereof, to one face or an opposite face of the cell zig assembly on which the zig for the positive electrode terminal and the zig for the negative electrode terminal are disposed, wherein the zig rotation inducing assembly allows the cell zig assembly to rotate around the rotation center shaft.

A rack-mounted device includes a case configured to include, in a width direction, a plurality of containment rooms each in which an electronic device is contained, a partition suspended from an upper wall of the case and configured to partition off the plurality of containment rooms adjacent to each other and guide the electronic device, and a support plate extending from a sidewall of the case into a containment room of the plurality of containment rooms and provided with a gap from a lower wall of the case to support the electronic device.

“PROFILE FOR ELECTRICAL CABINET” presents an invention that falls within the field of application of metal profiles for structural elements, more precisely in the field of metal profiles to electrical cabinets and enclosures. Comprising a side sealing area and, located in its relation, preferably at 90°, a front sealing area; an inner wall, a rear wall, an outer wall, an oblique wall and an isolating wall.

A data center cabinet has a base frame with a pair of front vertical posts, first bottom and top side-to-side beams connected to the front vertical posts, a pair of back vertical posts, second bottom and top side-to-side beams connected to the back vertical posts, and front-to-back beams connecting the front vertical posts and back vertical posts. The first and second bottom side-to-side beams each comprise an opening configured to allow a removable transport caster to pass through the opening, a first set of keyholes configured to receive and retain a set of mounting buttons of a first removable transport caster, and a second set of keyholes configured to receive and retain a set of mounting buttons of a second removable transport caster.
