Abstract: A protective jacket for covering an electrical device is provided. The protective jacket includes a first shell and a second shell. The first shell includes a front cover, a rear cover, and an elastic strip. The front and the rear covers are formed apart from each other and have an individual hollow for receiving the insertion of the device. The elastic strip is formed between these covers. A space is defined on the first shell by theses covers, and the elastic strip together. The second shell is configured to be disposed within the space of the first shell, and has a slot for receiving the insertion of the device. Therefore, the protective jacket conforms to the shape of the device and is capable of covering the device compactly for preventing damages due to collision and avoiding dust and mist pollution so as to increase the life of the device substantially.
