BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The exemplary disclosure generally relates to battery cover latching assemblies, particularly to a battery cover latching assemblies used in portable electronic devices. 
         [0003]    2. Description of Related Art 
         [0004]    As a power source, batteries are widely used in portable electronic devices, such as personal digital assistants (PDAs), cellular phones and etc. Conventional batteries are received in the electronic devices, and battery covers are designed to attach with housings of the electronic devices to package the batteries. The batteries have to be replaced by opening the battery covers when the batteries are damaged or can not be recharged with electricity any more. 
         [0005]    A clasp structure or latch structure is used with a conventional battery cover to engage with a housing of a portable electronic device. For example, a latch comprises a pair of hooks at one end of the battery cover and a locking pin protruding from the other end of the battery cover. Accordingly, a pair of troughs is defined in an end portion of a backside of a housing of the cellular phone, and a locking hole is defined in the other end portion of the backside of the housing. In assembly, the hooks are firstly inserted into the troughs in the backside of the housing. Then, the battery cover is pressed downwardly to the housing until the locking pin on the battery cover is inserted into the locking hole in the backside of the housing. The battery cover is thus assembled to the housing of the cellular phone. However, during disassembly, the battery cover is susceptible to being damaged, since a greater force is exerted thereon. As a result, it is inconvenient for a user to change a battery in the housing of the portable electronic device. 
         [0006]    Therefore, there is a room for improved in the arts.
