Techniques arrange a disk, a storage device, and a disk array. Such techniques involve: a bracket configured to be detachably coupled to a rack; and a button arranged in the bracket and configured to be movable under the action of an external force to decouple the bracket from the rack, wherein a first end of the button is configured to be operated by a user, and the end surface of the first end includes a first surface and a second surface, the second surface extending from the first surface towards a second end, opposite to the first end, of the button. Accordingly, such techniques not only can avoid accidental touch, improve heat dissipation efficiency, and provide a mark area, but also can help prevent loss of user data in a storage device and a disk array.

An electronic device having slots into each of which a circuit board is inserted includes faceplates attached respectively to the circuit boards on the side of an extraction direction. The faceplates each include two handle portions that are disposed respectively at both ends of a main body in the width direction and that extend in the extraction direction. The handle portion of one of two faceplates adjacent in the width direction that is located closer to the other of the faceplates, and the handle portion of the other faceplate that is located closer to the one faceplate, have respective distal ends shifted from each other in a thickness direction.

DIN rail installation kit including main body, spring hook, latch fastener and elastic element and combined with electronic device. When latch fastener is pulled down first to move to second position, buckle of latch fastener pushes down on hook body of spring hook, and after passing under hook body, hook end of hook body can be temporarily positioned on side wall of latch fastener. When user releases latch fastener, elastic element returns latch fastener, buckle is then buckled on buckle portion of hook body, and second buckle means of latch fastener is kept away from first buckle means of main body to present a removable state. When latch fastener is pulled down secondarily to return to first position, buckle is separated from buckle portion of hook body, and second buckle means and first buckle means are relatively buckled on DIN rail to exhibit a state of tight coupling.

A telescopic fan cage includes a main frame and a side frame which are slidably connected with each other to form a fan installation space. The side frame is capable of sliding toward the main frame to shrink the fan installation space, or sliding away relative to the main frame to expand the fan installation space. An apparatus case includes a casing and the telescopic fan cage. The telescopic fan cage is detachably disposed in the casing. Therein, the side frame is capable of sliding toward the main frame to shrink the fan installation space, so that the telescopic fan cage is at a transit state for moving in or out the casing; the side frame is capable of sliding away relative to the main frame to expand the fan installation space, so that the telescopic fan cage is at an installation state for being fixed in the casing.

The disclosure relates to a cage and an electrical device having the same, where the cage is configured to accommodate at least one expansion card and includes a cage body, a rail, and at least one holder. The cage body is configured to accommodate the at least one expansion card. The rail is fixed on the cage body. The rail has a groove configured for an insertion of the at least one expansion card. The at least one holder is movably disposed on the cage body. Part of the at least one holder is removably located in the groove. The at least one holder is configured to block the at least one expansion card in the groove.

A pre-strain unit for a T-bolt during a release process of two components connected by the T-bolt comprises a slider and a frame for providing a linear guiding for said slider during the release process. The pre-strain unit also includes means for pre-straining said slider in said frame against a head of said T-bolt to keep, during the release process, at least a part of the T-bolt protruding from the two connected components.

Techniques arrange a disk, a storage device, and a disk array. Such techniques involve: a bracket configured to be detachably coupled to a rack; and a button arranged in the bracket and configured to be movable under the action of an external force to decouple the bracket from the rack, wherein a first end of the button is configured to be operated by a user, and the end surface of the first end includes a first surface and a second surface, the second surface extending from the first surface towards a second end, opposite to the first end, of the button. Accordingly, such techniques not only can avoid accidental touch, improve heat dissipation efficiency, and provide a mark area, but also can help prevent loss of user data in a storage device and a disk array.

A tool-free hard disk bracket includes a base having abase body with a guide groove, and an engaging member connected to the base body. A frame includes a first side arm movably engaging with the engaging member. A handgrip is rotatably connected to one end of the base body. An operating unit includes an operating member releasably engaging with the handgrip and having a rotating shaft portion inserted rotatably and movably into the guide groove. The operating member is operated to rotate and release engagement with the handgrip, and is further operated to move along the guide groove toward the engaging member to push the engaging member to pivot and release engagement with the first side arm.

A cooling assembly includes a panel defining an opening, a cooling unit including an output and coupled to the panel such that the output at least partially covers the opening of the panel, and spring-loaded latch assemblies coupled to the panel and configured to couple the cooling assembly to an enclosure.

A removable mechanism for a hard drive is revealed. The removable mechanism includes an upper substrate and a base plate hanged and sliding below the upper substrate, and a control handle and a sliding board are set between the upper substrate and the base plate to carry each other. The control handle controls a pivot element sliding on an opening of the base plate. By carrying each other to carry a stop element of the base plate, the stop element slides on a concave opening for dismounting a storage device inserted to the removable drawing mechanism. Thereby, the present application is convenient for dismounting the storage device.
