Abstract: A communication module is provided, and is disposed in an equipment cabinet. The communication module includes a module body and a puller. The module body is detachably disposed in the equipment cabinet, and has a surface. The puller is disposed on the module body, and extends outside the surface. The puller includes a puller body and an elastic element, and the elastic element is connected between the puller body and the module body.

Abstract: A battery assembly includes a power module, a receptacle connector, a driving switch and a movable stop arm. The power module includes a battery control unit and a cell electrically connected to the battery control unit. The receptacle connector is disposed at the power module and electrically connected to the cell via the battery control unit. The receptacle connector includes an insertion opening. The driving switch is disposed corresponding to the receptacle connector and electrically connected to the battery control unit. A default setting of the driving switch is “switched off”. One end of the movable stop arm is outside of the insertion opening and blocks the same. The movable stop arm is movable toward the driving switch to touch and switch on the same.
