Abstract: A cover of a simple construction is provided which can deal with a distance variation between battery posts. The cover 6 is made of a rubber material and has a narrow box-like configuration. A bottomed middle portion of the cover 6 forms a tubular portion 107 through which a braided wire 3 of a battery connection terminal 1 is to be passed, and the opposite ends thereof form post cover portions 108 for covering battery posts 2. Further, slits 9 are formed in side walls between the tubular portion 107 and the post cover portions 108, so that the post cover portions 108 can be bent upward. In this way, since the cover 6 can be elongated and contracted according to a distance between the battery posts 2, it can be easily mounted and the action of an undesired force on the cover 6 due to the vibration of batteries 5 can be effectively prevented.

Abstract: A fixation arrangement for detachably mounting a battery pack onto a cellular phone includes two parallel guide rails defined on the cellular phone, a sloping depression defined between the guide rails and sloping outward to the guide rails, a recess defined adjacent to the sloping depression and in a position opposite to the sloping direction of the depression, and a coupling plate integrally formed with the battery pack and having two parallel lips corresponding to the guide rails for slidably engaging onto the cellular phone, a U-shaped slot provided in a position corresponding to the recess and the slot and defining a tongue portion with a tip over the slot when the battery pack is engaged with the cellular phone, a tab protruding from the tip of the tongue portion for inserting into the slot when the battery pack is engaged with the cellular phone, and two cutouts respectively extending between one of the lips and the U-shaped slot and in a direction substantially parallel to the guide rails.
