A chassis with built-in handles which do not add to dimensional clearance required for the chassis to be placed in a cavity includes a side plate, a mounting unit, and a handle. A mounting groove is defined on the side plate. The mounting unit is coupled to the side plate. The handle is partially clamped by the side plate and the mounting unit, and rotatably coupled with the side plate. By rotating the handle, the handle can be stored at least flush in the mounting groove.

A current transformer includes a first housing including a first handle portion and a first distal portion, a second housing including a second handle portion and a second distal portion, a first core mounted in the first distal portion, a second core mounted in the second distal portion, and a lock attached to the second handle portion at a pivot point, wherein the first housing is rotationally coupled to the second housing about a fulcrum point and the lock is rotatable about the pivot point into a closed position wherein the lock engages the first handle portion and prevents the first handle portion and the second handle portion from rotating towards each other.

A handle structure includes a handle board, a pair of washers and a fastener set. The handle board includes a plate, a fixing section, and a holding section. The fixing section is formed with a through hole. The pair of washers includes a first washer and a second washer. The fastener set includes a first fastener and a second fastener. The first fastener passes through the first washer, the through hole, the second washer and a connecting hole in order. The first fastener is fixed on the panel by the second fastener. The handle board is rotatable about the through hole. The handle structure of a server case may be simplified.

A chassis node coupling system includes a chassis node configured to be received at a first end of a chassis assembly, wherein the chassis node size exceeds the chassis assembly size. A latch assembly with one or more coupling assemblies may be configured to releasably couple the chassis node to the chassis assembly.

A tray is detachably assembled to a chassis. The chassis includes a first chassis guide post. The tray includes a tray body, a handle and a first sliding piece. The tray body includes a side wall and a through slot disposed on the side wall. The handle is pivotally connected to the side wall and includes a handle guide post. The first sliding piece includes a first groove and a second groove. The handle guide post is disposed in the through slot and the first groove. The first chassis guide post is detachably disposed in the second groove.

An apparatus includes an enclosure (e.g., an MCC bucket enclosure) having a cover configured to be opened, a disconnect switch positioned in the enclosure, and a shaft having a first end inserted in the disconnect switch and configured to actuate at least one switch in the disconnect switch by rotation of the shaft. The apparatus further includes a switch handle mechanism mounted on the cover, configured to receive a second end of the shaft when the cover is in a closed position, and comprising a switch handle configured to rotate the shaft. The switch handle mechanism may be configured to allow withdrawal of the second end of the shaft from the switch handle mechanism when the switch handle is in a first position to allow opening of the cover and to prevent withdrawal of the second end of the shaft from the switch handle mechanism wherein the switch handle is in a second position to prevent opening of the cover.

The present application describes apparatuses, systems, and methods for robust, adaptable, and deployable computing devices and radio systems. In one aspect, the present application describes a chassis for housing electronic componentry. The chassis includes a frame with a top plate and a bottom plate, an interface panel located on the chassis frame; a back panel located on the chassis frame opposite the interface panel, and a protective protrusion located at a corner of the chassis frame extending beyond the top plate and the bottom plate.

A notebook computer carrying device includes a carrier, a handle, and two telescopic members disposed at two ends of the handle and each including a first component and a second component, with the first components formed by extending the ends of the handle outward, and the second components disposed on the carrier. The first and second components of each telescopic member are movably connected, and the first component slides in a displacement direction from a first position to a second position. The displacement direction is defined as the start direction of the first position. A horizontal plane is defined by connecting the two ends of the handle. A vertical plane is defined to extend outward in the direction in which the horizontal plane faces the center of the handle. The displacement direction extends from the horizontal plane to vertical plane and forms an inclination angle relative to the horizontal plane.

A handheld mount assembly for portable electronic device includes a pistol style grip and suction cup assembly. The mount assembly functions as a gripping device for handheld use, a hands free stand, and a recharging station. The mount can be secured anywhere on the back of the electronic device, making the angle adjustable for stand use, and also allowing the user to position the device differently to accommodate his/her own needs. The mount can power/charge the portable wireless device as well as wirelessly connect to it and integrate its operational controls to those three tactile controls of the mount assembly.
