    DETAILED DESCRIPTION OF THE INVENTION
  • Refer to FIGS. 1A-1C. FIG. 1A is an explosion diagram of a broadband data processing device 100. FIG. 1B is a cross-sectional view of the broadband data processing device 100 of FIG. 1A after assembly. FIG. 1C is a side view of the broadband data processing device 100 of FIG. 1B.
  • The broadband data processing device 100 can process data interference problems for the asymmetric digital subscriber line (ADSL), the very-high-bit-rate digital subscriber line (VDSL), the G.fast broadband network or the cable broadband network.
  • The broadband data processing device 100 includes a casing 110, a circuit board 120, a cable connector 130, a fixing member 140, a stopping member 150 and a shielding component 160.
  • The casing 110 includes an upper casing 111 and a lower casing 112. The upper casing 111 and the lower casing 112 can be jointed to each other to protect the circuit board 120, a part of the cable connector 130, the shielding component 160, the fixing member 140 and the stopping member 150 within the casing 110. The cable connector 130 is disposed on and electrically connected to the circuit board 120. The shielding component 160 is electrically connected to and shields the cable connector 130. The shielding component 160 can reduce or even avoid an external magnetic or electric field interfering with the cable connector 130 and decrease the rate of packet loss of the cable connector 130 when receiving packet data. Thus, even when human body touches the cable connector 130, the cable connector 130, being shielded by the shielding component 160, still can maintain signal quality when receiving packet data.
  • The cable connector 130 includes a connection portion 131, a connector portion 132 connected to the connection portion 131, and a plurality of pins 133. As indicated in FIG. 1A, the connector portion 132 includes a grounding layer 1321, an insulation layer 1322 and a conductive layer 1323, wherein the insulation layer 1322 is formed between the grounding layer 1321 and the conductive layer 1323 and separates the grounding layer 1321 from the conductive layer 1323. An external cable is connected to the conductive layer 1323 through which the external cable is further electrically connected to the circuit board 120. The connection portion 131 is electrically connected to the grounding layer 1321 and used as a grounding portion of the cable connector 130. As indicated in FIG. 1B, a plurality of pins 133 connected to the connection portion 131 pass through the circuit board 120 and are extend to the lower surface 120b of the circuit board 120 to electrically connect the circuit (not illustrated) disposed on the lower surface 120b of the circuit board 120. Besides, the pins 133 can be fixed on the lower surface 120b of the circuit board 120 by way of soldering.
  • As indicated in FIG. 1B, the connector portion 132 is extended from the casing 110, such that the connector portion 132 can be conveniently connected to the external cable. For example, the lower casing 112 includes a through hole 112a, wherein the connector portion 132 of the cable connector 130 passes through the through hole 112a and is protruded from the casing 110. Furthermore, the outer dimension of the fixing member 140 is smaller than the inner dimension of the through hole 112a. Thus, although the shielding component 160 is disposed within the casing 110, the fixing member 140 still can enter the casing 110 from the outside of the casing 110 through the through hole 112a to fix the shielding component 160.
  • As indicated in FIG. 1A and 1B, the connector portion 132 has an external thread 1324, and the fixing member 140 is such as a nut. The fixing member 140 can be engaged with the external thread 1324 to fix the shielding component 160, for example, to fix the shielding component 160 between the stopping member 150 and the fixing member 140. The stopping member 150 is such as a nut. Thus, two nuts can fix the shielding component 160, and has an anti-loose effect. In comparison to the conventional method in which the shielding component 160 is fixed using an adhesive, in an example of the present disclosure, the nut is used as the fixing member 140 and therefore avoids the deterioration problem of adhesive.
  • The connection portion 131 is connected to the circuit board 120 and has a front surface 131f and an upper surface 131u. The surface 131f is one side of the connection portion 131 adjacent to an external cable 10, that is, a surface facing the external cable 10 (in the +X direction). The upper surface 131u is one side of the connection portion 131 farther away from the circuit board 120, that is, a surface backing the circuit board 120. The front surface 131f is similar to or substantially vertical to the upper surface 131u. The shielding component 160 shields at least a part of the front surface 131f or a part of the upper surface 131u to reduce the rate of packet loss of the broadband data processing device 100 when receiving packet data. In the example as indicated in FIG. 1B, the shielding component 160 shields the entire front surface 131f.
  • As indicated in FIG. 1A, the shielding component 160 has a penetrating hole 160a through which the connector portion 132 passes. The connector portion 132 can further be protruded from the penetrating hole 160a. As indicated in FIG. 1B, the shielding component 160 has a length L1 along a length direction Y, and the connection portion 131 has a length L2 along a length direction Y, wherein the length L1 is substantially two times of the length L2. Thus, the rate of packet loss of the broadband data processing device 100 when receiving packet data can be effectively reduced.
  • Additionally, the shielding component 160 has a height H1 along a thickness direction Z, and the connection portion 131 has a height H2 along a thickness direction Z, wherein the height H1 is substantially at least one time of the height H2. Thus, the rate of packet loss of the broadband data processing device 100 when receiving packet data can be effectively reduced.
  • Moreover, the shielding component 160 can be formed of a conductive material containing copper or iron. The shielding component 160 can be realized by a conductive paper or a conductive piece, wherein the conductive paper is such as a copper foil, and the conductive piece is such as an iron piece or iron plate. If the shielding component 160 has a larger thickness, the shielding component 160 can be formed using a stamping method. In assembly, the shielding component 160 is placed or fixed on the lower casing 112 in advance, the circuit board 120 is assembled to the lower casing 112, and the fixing member 140 is locked on the connector portion 132 to fix the shielding component 160. Or, the fixing member 140 is fixed on the shielding component 160 in advance, and the circuit board 120 is assembled to the lower casing 112.
  • FIG. 2 is a cross-sectional view of a broadband data processing device 200. The broadband data processing device 200 includes a casing 110, a circuit board 120, a cable connector 130, a fixing member 140 and a shielding component 160. The broadband data processing device 200 of the present example is similar to the broadband data processing device 100, but is different in that the broadband data processing device 200 omits the stopping member 150.
  • As indicated in FIG. 2, the front surface 131f of the connection portion 131 of the cable connector 130 is extended forward and protruded over the circuit board 120, such that the shielding component 160 can contact the front surface 131f of the connection portion 131 outside the circuit board 120, hence avoiding the shielding component 160 interfering with the circuit board 120. Since the shielding component 160 is electrically connected to the grounding layer of the cable connector 130 through the front surface 131f and shades the entire front surface 131f of the connection portion 131, the rate of packet loss of the broadband data processing device 200 when receiving packet data can be effectively reduced.
  • Refer to FIGS. 3A and 3B, FIG. 3A is a cross-sectional view of a broadband data processing device 300 according to another embodiment of the invention. FIG. 3B is an external view of a shielding component 360 of the broadband data processing device 300 of FIG. 3A.
  • The broadband data processing device 300 includes a casing 110, a circuit board 120, a cable connector 130, a fixing member 140 and a shielding component 360. The broadband data processing device 300 of the present example is similar to the broadband data processing device 100, but is different in the structure of the shielding component 360.
  • The shielding component 360 includes a front shielding portion 361, an upper shielding portion 362 and a lower shielding portion 363. The structure of the front shielding portion 361 is similar to that of the shielding component 160. The front shielding portion 361 directly contacts the front surface 131f of the connection portion 131. The upper shielding portion 362 and the lower shielding portion 363 are respectively connected to the upper edge and the lower edge of the front shielding portion 361 and are respectively extended towards the upper surface 131u of the connection portion 131 of the cable connector 130 and towards the lower surface 120b of the circuit board 120 to shield the upper surface 131u of the connection portion 131 and the lower surface 120b of the circuit board 120. As indicated in FIG. 3A, the lower shielding portion 363 shields the area of distribution of a plurality of pins 133 of the cable connector 130, and the upper shielding portion 362 shields the entire upper surface 131u of the connection portion 131 of the cable connector 130. Thus, the rate of packet loss of the broadband data processing device 300 when receiving packet data can be effectively reduced.
  • The shielding component 360 can omit one of the upper shielding portion 362 and the lower shielding portion 363 and still can reduce the rate of packet loss of the broadband data processing device 300 when receiving packet data.
  • To summarize, the broadband data processing device disclosed in above examples of the disclosure has a shielding component electrically connected to the cable connector to reduce or even avoid an external magnetic or electric field interfering with the cable connector. Thus, although when human body touches the cable connector, the rate of packet loss of the broadband data processing device when receiving packet data will not be increased, and signal quality can be maintained or enhanced. Based on actual measurement, when receiving packet data, the rate of packet loss of the conventional broadband data processing device without a shielding component is between 0.002∼4.857%. In comparison, through the protection of the shielding component, the broadband data processing device of the invention can reduce the rate of packet loss to 0.002∼0.34% or even 0.
