Embodiment

See also shown in Figure 2ly, the utility model is a kind of casing device that has circuit unit, and circuit unit 10 is arranged at the inner surface of this housing 20, can reduce the assembling of electronic building brick, and save cost.

This device can apply to the electronic product of simple circuit, wherein as flash disk, business card scanner, mouse, scanner etc., see also Fig. 2 to the flash disk that has the casing device of circuit unit illustrated in fig. 4, this device includes housing 20 and circuit unit 10, wherein this housing 20 includes upper shell 21 and lower house 22, and this upper shell 21 and this lower house 22 have inner surface and outer surface respectively; This circuit unit 10 has last circuit unit 11 and reaches circuit unit 12 down, it is arranged at the inner surface of this upper shell 21 and this lower house 22 respectively accordingly, electronic building brick 30 is as the IC assembly, light-emitting diode and resistance etc. can or utilize bonding wire (wire bound) (figure do not show) to be electrically connected on this circuit unit 11 maybe on this time circuit unit 12 in surface adhering mode (SMD), should go up circuit unit 11 and this time circuit unit 12 can be by electrical connection module 40 as the conductive foam gluing on it, make upper and

lower circuit unit

11,12 electrically connect mutually, and electric connector 50 is electrically connected on this circuit unit 10, so only needs this upper shell 21 of interlocking and this lower house 22 promptly to finish this electronic product.

See also shown in Figure 5, this electronic product is a mouse, wherein this mouse has upper shell 21 and lower house 22, and this circuit unit 10 is arranged at the upper surface of this lower house 22, and other electronic building brick 30 is electrically connected on this circuit unit 10, so only need again machine components such as roller to be assembled into the upper surface of this lower house 22, and upper shell 21 is locked on this lower house 22, to finish the assembling of this mouse.

Therefore, this casing device that has circuit unit both can reduce the setting of printed circuit board (PCB), and reduced the setting of the fixing assembly or the interlocking assembly of housing, therefore save time and the manufacturing procedure that printed circuit board (PCB) is assembled in this housing, and these circuit units can modularization, print or the glutinous inner surface that places this housing, so the profile of the shell body of this electronic product conversion arbitrarily, and do not need other design circuit unit, and the fixing assembly of this housing or the design of interlocking assembly can reduce, therefore the processing cost of mould can be reduced, and then increase competitiveness of product.
