Abstract: A protective shell is provided for an electronic device with a built-in antenna. The protective shell includes a plate body, a first penetrating part and an auxiliary grounding element. The first penetrating part is located on the plate body in correspondence with the built-in antenna of the electronic device. The first penetrating part is made of insulating material. The auxiliary grounding element is disposed on the plate body in correspondence with a ground wire of the built-in antenna of the electronic device.

Abstract: An electronic device including a casing, at least one connector and a waterproof elastic module is provided. The casing includes at least one first hole. The at least one connector is disposed in the casing, the at least one connector penetrates the at least one first hole and is exposed out of the at least one first hole, and at least one gap exists between walls of the casing encircling the at least one first hole and the corresponding at least one connector. The waterproof elastic module has at least one second hole, the waterproof elastic module sleeves the at least one connector, the at least one connector is exposed out of the at least one second hole, the waterproof elastic module covers and wraps around the at least one connector, and the at least one gap is filled with the waterproof elastic module.

Abstract: A base includes an engaging module, a release button and a code lock module. The release button presses the engaging module to release the host. The code lock module includes a cam assembly, a plurality of dials and a retaining assembly. The cam assembly includes cams arranged along an axis. Each of the dials has a recess for containing one of the cams. The retaining assembly includes a lock head and an elastic element. When one of the dials is rotated to separate one of the cams from the recess, the cam assembly pushes the lock head to be fastened to the release button and make the elastic element deform. When the dials are rotated to allow each recess to contain one cam, the cam assembly moves away from the lock head, and the elastic element restores to drive the lock head to be separated from the release button.

Abstract: An industrial computer includes a first casing, a second casing, a storage unit, a cover, and a heat dissipation unit. The second casing and the first casing form a closed casing, and the outside of the second casing has a containing area. The storage unit is disposed at the containing area. The cover is removably assembled at the second casing to cover the containing area and contact the storage unit. The heat dissipation unit is disposed at the cover.

Abstract: A computer includes a casing, a carrier, a card reader, and a cover. The casing has a containing space and an opening, and the opening communicates with the containing space. The carrier is located in the containing space and is slidably connected with the casing. The card reader is disposed at the carrier. The cover is pivotally connected with the casing, and the cover has a sealing element for covering and sealing the opening.

Abstract: An industrial computer includes a first casing, a second casing, a storage unit, and a heat dissipation unit. The second casing and the first casing form a closed casing, and outside of the second casing has a containing area. The storage unit is disposed in the closed casing, contacts the second casing, and corresponds to the containing area. The heat dissipation unit is disposed at the containing area.
