Abstract: This disclosure is directed to a rugged plug having a connector, an elastic inner sheath and a slidable rigid sheath. The connector has a coupling end. The elastic inner sheath sleeves the connector. The elastic inner sheath has an elastic arm, and a hook is protruded from one lateral side of the elastic arm. The hook protrudes from the side of the elastic inner sheath and a tip of the hook is a curved surface, an actuating slope is defined on the elastic arm, and a direction normal to the actuating slope is biased toward the coupling end of the connector. The slidable rigid sheath movably sleeves the elastic inner sheath, the slidable rigid sheath cover the actuating slope and the hook is located outside the slidable rigid sheath, the slidable rigid sheath has an actuating structure and the actuating structure abuts against the actuating slope.

Abstract: A male plug and a female receptacle and a docking structure thereof include a male plug and a female receptacle docked with each other. When the male plug and the female receptacle docked with each other, the male plug is fitted with the female receptacle using a horizontal holding force provided by a first fastening structure, and is fitted with the female receptacle using a vertical holding force provided by a second fastening structure, hence further reinforcing plugging stability between the male plug and the female receptacle by the horizontal and vertical holding forces.

Abstract: A connector plug, abutting structure of the same, and electrical connection mechanism having the same are provided. The connector plug includes a connection body and an outer casing member. The outer casing member is disposed outside the connection body and includes an inner casing, an outer casing movably fitted to the inner casing from outside, and a resilient component acting between the inner casing and the outer casing. At least one hook hole is disposed at the front end of the outer casing. At least one engaging arm is disposed on the inner casing and extends forward to form a hook portion. At least one engaging hole is disposed on a receptacle. When a plug is plugged into the receptacle, the hook portion becomes engaged with the engaging hole to achieve connection.

Abstract: A connector plug, abutting structure of the same, and electrical connection mechanism having the same are provided. The connector plug includes a connection body and an outer casing member. The outer casing member is disposed outside the connection body and includes an inner casing and an outer casing enclosing the inner casing. At least one engaging arm is disposed on the inner casing and has a pressing portion protruding from the outer casing and an engaging portion extending forward from the pressing portion and hanging on the sidewall of an insertion port of the connection body. At least one engaging hole is defined on a receptacle. When a plug is plugged into the receptacle, the engaging portion becomes engaged with the engaging hole to achieve connection.

Abstract: A function expansion device and an electronic device including the same. The function expansion device includes a casing, an expansion device and a handle. The casing has a main space and a side space. The expansion device is accommodated in the main space of the casing. The handle is slidably disposed in the side space and is thus allowed to move between a housed position and an extracted position along a sliding direction of the casing by gravitational force. A first protruding length of the handle relative to the casing when the handle is at the housed position is less than a second protruding length of the handle relative to the casing when the handle is at the extracted position. When the handle is at the extracted position, the handle is pressed against the casing to enable the casing to be moved along with the handle.

Abstract: A male plug and a female receptacle and a docking structure thereof include a male plug and a female receptacle docked with each other. When the male plug and the female receptacle docked with each other, the male plug is fitted with the female receptacle using a horizontal holding force provided by a first fastening structure, and is fitted with the female receptacle using a vertical holding force provided by a second fastening structure, hence further reinforcing plugging stability between the male plug and the female receptacle by the horizontal and vertical holding forces.

Abstract: A cable clip disposed at an electronic device and adapted to clamp a cable is provided. The cable clip comprises a first clamping unit and a second clamping unit. The first clamping unit has a first clamping portion and two spaced-apart anti-pulling portions. The second clamping unit has a second clamping portion corresponding in position to the first clamping portion and two fixing portions corresponding in position to the two anti-pulling portions, to which the two anti-pulling portions are connected respectively. The cable is clamped between the first and second clamping portions when the first and second clamping units fit together in operation, and thus part of the electronic device is confined between the two anti-pulling portions, allowing the first clamping unit to bear a pulling force by one of the two anti-pulling portions. The cable clip prevents detachment of the cable's connector otherwise electrically connected to the electronic device.

Abstract: A dock with detachable support assembly includes a base and a support assembly. The base includes a first case and a first connector. The first case has a plurality of connection hole and the first connector is disposed in the first case. The support assembly is detachably assembled to the base. The use of the detachable support assembly makes the dock replace required support assembly to fit a plurality of tablets with different sizes. The user can buy the support assembly according to the size of the tablet. When the user needs to install a different size tablet, the user only needs to remove the original support assembly and sets up the necessary support assembly to the base.
