Abstract: A keylock structure and an electronic device using the same are provided. The electronic device includes a first casing and a second casing. The keylock structure includes a body and a hook. The hook and the body are connected with each other and form a concave portion. When the hook passes through a through hole of the first casing, the concave portion is fastened at the through hole. When the second casing is assembled to the first casing, a circuit switch in the second casing is embedded into a recess of the hook and is fixed to the same, such that the circuit switch is combined with the keylock structure.

Abstract: A mobile phone keypad design includes a keypad and a joystick. The keypad includes multiple keys. The joystick is disposed between several neighboring keys in the keypad. When the joystick is tilted, a corresponding signal is output.

Abstract: A multi-layered printed circuit board includes a base member, a lower layer disposed above the base member, an upper layer disposed above the lower layer, and a plurality of vertical spacer posts sandwiched between the lower and upper layers so as to space apart the lower and upper layers from each other. Each spacer post includes an upper portion having an end face abutting against the upper layer and being formed with an inner threaded hole extending inwardly and axially from the end face, and a threaded lower portion. The threaded lower portion of each of the spacer posts extends a through hole in the lower layer to fasten threadedly the base member, and defines an outer diameter that is greater an inner diameter defined by the inner threaded hole in the upper portion.

Abstract: A hang tag for sockets. The hang tag includes a hanging card portion having a hanging hole. A neck portion is joined underneath the hanging card portion. A screw-joining portion is joined underneath the neck portion, which has a screw-thread structure screwed to the socket, resulting in the entire hang tag for sockets being able to be displayed and secured by the screw-thread structure of the screw-joining portion. The neck portion is able to be clamped onto by wrenches or other similar tools, and the sockets that can easily be joined onto and removed from the screw-thread socket.

Abstract: A hang tag for sockets comprised of a hanging card portion having a hanging hole; a neck portion joined underneath the hanging card portion, having at least a pair of parallel sides; and a screw-joining portion joined underneath the neck portion, which has a screw-thread structure screwed to the socket, resulting in the entire hang tag for sockets being able to be displayed and sold by the screw-thread structure of the screw-joining portion, thus enabling, also, with the neck portion being able to be clamped onto by wrenches or other similar tools, sockets that can easily be joined onto and removed from the screw-thread socket.
