  • Patent number: 8905764
    Abstract: A rotary plug includes a base, a plurality of annular slot structures, a plurality of conductive components, a bridging component and a plurality of terminals. An accommodating space is formed on the base. The annular slot structures are respectively disposed on an inner wall of the accommodating space. Each conductive component is disposed inside the corresponding annular slot structure. A protrusion of the conductive component inserts into a hole formed on the annular slot structure. The bridging component is rotatably disposed inside the accommodating space. A first end of the terminal protrudes from a bottom of the bridging component. A second end of the terminal protrudes from a lateral surface of the bridging component and movably inserts into the annular slot structure to electrically contact the conductive component.

  • Publication number: 20140131934
    Abstract: A clamp fixture includes a base, a bridging component, an actuating component, a contacting component and a pushing component. The base is disposed on a foundation. A first end of the bridging component pivots to a first side of the base. A first end of the actuating component pivots to a second side of the base. The contacting component is disposed on a second end of the actuating component. The pushing component includes a body, two pivot structures and a handle. The pivot structures are disposed on an end of the body for respectively pivoting to the bridging component and the actuating component. The handle is disposed on the other end of the body. The handle moves at a first direction, the bridging component and the actuating component can move at a second direction, so as to move the contacting component close to or away from a work piece.

  • Patent number: 8649175
    Abstract: A locking mechanism for locking an outer shell includes a frame adapted to be stacked with an outer shell and having a through hole for extension of an engaging piece of the outer shell therethrough, a locking element disposed movably on the frame, and a release button disposed slidably on the frame. The locking element has a hook-engaging portion, and a contact portion opposite to the hook-engaging portion. The hook-engaging portion is extendable to the through hole for engaging releasably the engaging piece. The release button has one end abutting against the contact portion. The release button is operable to push the contact portion, which in turn moves the hook-engaging portion to disengage from the engaging piece.
