DIN rail installation kit including main body, spring hook, latch fastener and elastic element and combined with electronic device. When latch fastener is pulled down first to move to second position, buckle of latch fastener pushes down on hook body of spring hook, and after passing under hook body, hook end of hook body can be temporarily positioned on side wall of latch fastener. When user releases latch fastener, elastic element returns latch fastener, buckle is then buckled on buckle portion of hook body, and second buckle means of latch fastener is kept away from first buckle means of main body to present a removable state. When latch fastener is pulled down secondarily to return to first position, buckle is separated from buckle portion of hook body, and second buckle means and first buckle means are relatively buckled on DIN rail to exhibit a state of tight coupling.

An electronic device with an extraction device and an extraction device thereof are provided. The extraction device includes a housing and a handle. A front side of the housing has two ends. The two ends have a pivot and a limiting member, respectively. The limiting member has at least one limiting recessed portion that has a draw bar and a hook. Two ends of the draw bar have a long groove and a pulling and gripping portion, respectively. The pulling and gripping portion is connected to the hook, the pivot is disposed in the long groove, and the hook can engage in the at least one limiting recessed portion along a sliding direction to be in an engaged state. The handle in the engaged state can slide along an unlocking direction so to depart from the at least one limiting recessed portion to be in an unengaged state.

A drive carrier for retaining a persistent storage drive in an enclosure. The drive carrier includes a mounting bracket, a handle coupled to the mounting bracket, and an electromagnetic interference (“EMI”) shielding apparatus disposed between mounting bracket and at least a portion of the handle. The mounting bracket is shaped to be coupled to the persistent storage drive. The EMI-shielding apparatus includes a plurality of EMI-shielding fingers. Each EMI-shielding finger includes a lower surface, an upper surface that is approximately parallel to the lower surface, and a contoured surface extending between the lower surface and the upper surface.

A pushing auxiliary includes a body part and a screw body. The body part includes an abutting part and a combination part, the combination part is movably combined with an object; the screw body is movably combined with the body part, and the screw body is screwed with a nut body of another object for driving the abutting part to abut against an abutted body, in order to drive the object to move. Accordingly, the pushing auxiliary of the present disclosure has the effects of simplicity of operation, saving labor and convenience.

The disclosure relates to a cage and an electrical device having the same, where the cage is configured to accommodate at least one expansion card and includes a cage body, a rail, and at least one holder. The cage body is configured to accommodate the at least one expansion card. The rail is fixed on the cage body. The rail has a groove configured for an insertion of the at least one expansion card. The at least one holder is movably disposed on the cage body. Part of the at least one holder is removably located in the groove. The at least one holder is configured to block the at least one expansion card in the groove.

An insertion tool for assisting in the insertion of an OCP 3.0 type expansion card in an expansion card slot of a computer system is disclosed. The expansion card may be a pull tab type form factor that does not have a mechanism such as an ejector latch to assist in applying force to insert the card. The expansion card has a front panel opposite a distal edge connector. The tool has a handle and a head coupled to the handle. The head has two contact areas that contact different areas of the front panel of the expansion card. For example, one of the contact areas may be an extended side arm and the other area may be a lateral rib extending from the head.

A mounting device is disclosed. The mounting device has a handle rotatable between an open position and a closed position. The handle has latching features at each end that couple to mating latching features. As the handle is rotated from its open position towards its closed position, the latching features force the handle towards the mating latching features.
