Patent ID: 7257006

Claim:
An assembling electronic device, comprising: a plurality of functional modules, wherein each of said functional modules has a terminal; a characterized casing having a plurality of receiving cavities, wherein each of said functional modules is shaped and sized to detachably receive in said respective receiving cavity so as to securely retain said functional module in said characterized casing in position; and a terminal circuit provided at said characterized casing to electrically connect with said terminals of said functional modules when said functional modules are detachably received in said receiving cavities respectively so as to form a complete circuit for said functional modules, such that each of said functional modules is replaceably mounted in said characterized casing for enhancing a user-personalizability, wherein said terminal circuit comprises at least a signal cable having a plurality of connectors extended to said receiving cavities respectively, wherein said connectors of said signal cable is electrically plugged into said terminals of said functional modules respectively to electrically connect said functional modules with each other, wherein said characterized casing further has a guiding groove formed thereon, wherein said signal cable is received in said guiding groove after said signal cable is electrically connected with said functional modules, such that said signal cable is held along said guiding groove to prevent said signal cable from intertwining within said characterized casing.
