Abstract: An electronic device includes a shielding shell, a circuit board, and a connector providing a temporary or permanent electrical connection which has integrity. The shielding shell includes at least one elastic fixing tab. The circuit board includes a signal piece and a connecting member partially surrounding the signal piece. The connector includes a plug detachably plugged in the shielding shell to electronically couple with the signal piece. The plug includes at least one notch to engage with the fixing tab.

Abstract: A component holder for a component includes a bracket and two fixing members. The bracket includes a bottom plate and a frame including a number of first side plates and two second side plates perpendicularly to each other. The first side plates and the second side plates are attached to the bottom plate to form a receiving space for receiving the component. The two fixing members are coupled to the two second side plates. Each fixing member includes an elastic board extending into the receiving space and spaced from the corresponding second side plate, to press against the component in a direction perpendicular to the corresponding second side plate.

Abstract: A crash preventing apparatus includes a latching device and an actuator. The latching device includes a rotatable member, a first gripping member, and a second gripping member. The rotatable member includes a first arm and a second arm. The first gripping member and the second gripping member are respectively fixed to a first portion of the first arm and a first portion of the second arm. The actuator includes a shaft, a first line, a second line, and a line connector. A first end of the first line and a first end of the second line pass over the shaft in opposite directions, and are respectively connected to a second portion of the first arm and a second portion of the second arm. A second end of the first line and a second end of the second line are connected to the line connector.

Abstract: A display device includes an inner frame, a display panel, and an outer frame. The inner frame includes four first sidewalls. The display panel includes four second sidewalls respectively secured to the four first sidewalls of the inner frame. The outer frame includes four third sidewalls surrounding a support plate. The display panel is connected to the support plate. The four first sidewalls of the inner frame are spaced from the four third sidewalls of the outer frame. A number of springs are arranged between each first sidewall and the corresponding third sidewall.
