Abstract:
A wireless network interface device with concealable electrical interface includes a casing unit, a wireless receiver unit, an elastic assembly and an actuator. The casing unit has an outer body, an interface opening, and an actuator opening. The wireless receiver unit has a receiving module and an I-shaped groove. The I-shaped groove has a first recess and a second recess bridged by a connecting recess. The elastic assembly has at least one first elastic member. The actuator has a second elastic member, a releaser member, and a locking member. When the locking member is engaged to the first recess, at least one first elastic member is compressed with the electrical interface being concealed inside the casing unit. When the releaser member is pressed, the locking member disengages from the first recess, and at least one first elastic member pushes the receiving module to expose the electrically connected electrical interface.
Abstract:
A wireless network receiver for selectively receiving or exposing an electrical connector includes a wireless network receiving unit, a two-stage switch unit and a slidable cover unit. The wireless network receiving unit includes a wireless network receiving module, and the electrical connector is electrically connected to and disposed on one end of the wireless network receiving module. The two-stage switch unit includes a movable module disposed in the wireless network receiving module, and the movable module is selectively positioned in a first position or a second position. The slidable cover unit covers slidably one part of the wireless network receiving module and connects the two-stage switch unit, and the electrical connector is selectively received by or exposed from the slidable cover unit according to the position of the movable module in the first position or the second position.
Abstract:
An external connection box and a case body thereof are for receiving a storage device therein. The external connection box for a storage device has a case body, a front cover, and a rear cover. The case body has an outer casing and at least one metal inner plate. The outer casing forms a receiving space therein. The at least one metal inner plate is disposed at an inner surface of the outer casing. The at least one metal inner plate has a plurality of resilient fins, and the resilient fins extend into the receiving space. As such, the case body of the external connection box for a storage device of the present invention has a heat dissipating function, an EMI shielding function, a reinforcing function, and a cushioning function.
Abstract:
The present invention provides a button apparatus for an electrical device having a circuit board with M switch devices wherein M is a positive integer number. The button apparatus includes a body and a pillar. The body has M protrusions respectively corresponding to the M switch devices for selectively actuating the M switch devices. The pillar has a first end and a second end. The second end has a projection used as a pivot. The first end presses against a central part of the body. When the body is pushed downward, the body presses upon the first end and the projection touches against the circuit board for controlling one of the M protrusions to selectively actuate one corresponding switch device.
Abstract:
A wireless network receiver includes a heat-dissipating unit, a wireless network receiving module, an electrical connecting unit, and a shell unit. The heat-dissipating unit has at least one main heat-dissipating body and a front heat-dissipating body extended forward from the main heat-dissipating body. The wireless network receiving module is disposed on the heat-dissipating unit, and the wireless network receiving module includes a first substrate unit and a second substrate unit electrically connected to the first substrate unit. The electrical connecting unit includes an electrical connecting casing contacting the front heat-dissipating body and enveloping the front heat-dissipating body and a front portion of the first substrate unit. The shell unit includes a shell module for selectively exposing or hiding the electrical connecting unit.
