Claim:
A housing comprising: a first outer shell; a second outer shell; and a hook configuration configured for assembling the first outer shell on the second outer shell, and the hook configuration comprising: two clasp units set in the first outer shell, and each of the two clasp units comprising a first clasp body and a first magnet mounted in the first clasp body; and two hook units set in the second outer shell, and each of the two hook units, corresponding to one of the two clasp units, comprising a first hook and a second magnet mounted in the first hook; wherein two parallel surfaces of each of the first magnets and the corresponding second magnet have opposite polarities to generate an attracting force, the two hook units move relative to the second outer shell by the attracting force, and drive the first hook to move to engage with the corresponding first clasp body; and wherein, when the second outer shell is pushed by an exterior force to move relative to the first outer shell, each of the first magnets is separated from the corresponding second magnet, and the first hook is driven by a movement of the second outer shell to separate from the first clasp body.
