Abstract: A ground terminal is mounted on a circuit board. The circuit board has a through-hole. The ground terminal includes a main body, a tail part and an insertion part. The tail part is connected to the main body. The insertion part is extended downwardly from the tail part and aligned with the through-hole of the circuit board, and has a hooking element. After the insertion part is penetrated through the through-hole, the hooking element is sustained against a lower surface of the circuit board so as to facilitate fixing the ground terminal onto the circuit board.

Abstract: A KVM switch system and switching method are described. The KVM switch system for switching between a first computer and a second computer includes a first KVM switch, a second KVM switch and the synchronization cable. The first computer provides a first video source and a second video source. The second computer provides a third video source and a fourth video source. The synchronization cable couples the first KVM switch to the second KVM switch and transmits a control signal. In the beginning, the first KVM switch is coupled to the first video source and the second KVM switch is coupled to the second video source. When the first KVM switch is switched from the first video source to the third video source of the second computer, the first KVM switch controls the second KVM switch to select the fourth video source of the second computer by the control signal transmitted on the synchronization cable.

Abstract: A handle structure is provided. The handle structure adapted to secure a case in a frame of an electrical apparatus includes at least a handle, wherein the frame includes a protruding portion extending from the frame. Each of the handles includes a stem portion, an engaging portion pivotally connected to the case and further comprising a recess portion for engagement with the protruding portion of the frame, and a leaf spring structure being set at the other end of the stem portion for securing the case in the frame, wherein the handle is engaged with the case and the case is engaged with the frame when the case is secured in the frame, and the leaf spring structure is used for disengaging the handle from the case when the case is retracted from the frame.

Abstract: A composite heat-dissipating structure includes: a first heat-dissipating element detachably connected to a heat-generating device, and a second heat-dissipating element detachably connected to the first heat-dissipating element, wherein the first and second heat-dissipating elements are ones of standard pieces and portions of standard pieces and are flexibly assembled and changed without a necessity of redesigning a mold and a circuit board for the structure so as to dissipate a heat generated by the heat-generating device, and to meet space limitations for the heat-generating device being mounted on the first heat-dissipating element, for the first heat-dissipating element being mounted on the second heat-dissipating element, and for the second heat-dissipating element being mounted on the circuit board.

Abstract: A composite heat-dissipating structure applied in a circuit board is disclosed. The composite heat-dissipating structure includes a first heat-dissipating element connected to a heat-generating device, and a second heat-dissipating element detachably connected to the first heat-dissipating element, wherein the selection of the first and second heat-dissipating elements is dependent on a heat-generating rate of the heat-generating device and a particular space limitation for achieving a heat-dissipating effect.
