[Part Name] Lead assembly, lead wire assembly and lead wires [Description] used to transport power around the internal circuit [Manufacturing] Flexible plastic molding is used for the PVC and the copper is drawn into thin wires [Reason for Using Materials] PVC is used for insulation and copper is used because of the efficiency in conducting electricity [Forces Applied] none [Functional/Cosmetic] the wires are functional because they transfer power within the circuit [Quantity] 4 [Complexity] 1 [Reason for Shape] 
The wires are flexible to allow the wires to blend in with the internal circuit and not require extra space
