Description

Broadband data processing device

The present invention relates to a data processing apparatus, and more particularly to a broadband data processing apparatus.

Conventional broadband data processing devices, such as data processing devices using G.fast technology, have cable connectors that are exposed to facilitate connection to external network routes. Since the cable connector is exposed, it is inevitable that the human body will touch the exposed cable connector to form a noise, which will interfere with the data signal transmitted through the cable connector, causing the broadband data processing device to receive a large amount of data (such as a packet). A missed (dropped) phenomenon occurs.

Therefore, it is urgent to propose a new technology to improve the aforementioned interference problem.

Accordingly, the present invention proposes a new broadband data processing apparatus to improve the conventional problems.

According to an embodiment of the present invention, a broadband data processing apparatus is proposed. The broadband data processing device includes a casing, a circuit board, a cable connector and a shielding component. The circuit board is disposed in the casing. The cable connector is configured and electrically connected to the circuit board. The shielding component is electrically connected to a ground layer of the cable connector, and the shielding cable Wire connector.

1A to 1C, FIG. 1A is an exploded view of a broadband data processing device 100 according to an embodiment of the present invention, and FIG. 1B is a cross-sectional view showing the assembled broadband data processing device 100 of FIG. 1A, and 1C is a side view of the broadband data processing apparatus 100 of FIG. 1B.

The broadband data processing device 100 can process, for example, an Asymmetric Digital Subscriber Line (ADSL), super high. Data interference problems in a fast-high-bit-rate digital subscriber line (VDSL), G.fast broadband network or cable (wideband) cable network.

The broadband data processing device 100 includes a housing 110, a circuit board 120, a cable connector 130, a fixture 140, a stop 150, and a shielding member 160.

The casing 110 includes an upper casing 111 and a lower casing 112. The upper case 111 and the lower case 112 can be docked to protect the circuit board 120, a portion of the cable connector 130, the shielding member 160, the fixing member 140, and the stopper 150 in the casing 110. The cable connector 130 is configured and electrically connected to the circuit board 120, and the shielding component 160 is electrically connected and shields the cable connector 130. The shielding element 160 can reduce the interference of the external magnetic field or electric field on the cable connector 130 to reduce the packet loss rate of the cable connector 130 when receiving the packet data. In this way, even if the human body touches the cable connector 130, the shielding of the shielding member 160 can maintain the signal quality of the cable connector 130 when receiving the packet data.

The cable connector 130 includes a connecting portion 131 and a joint portion 132 and a plurality of pins 133 that are connected. As shown in FIG. 1A, the joint portion 132 includes a ground layer 1321, an insulating layer 1322, and a conductive layer 1323. The insulating layer 1322 is formed between the ground layer 1321 and the conductive layer 1323 to isolate the ground layer 1321 and the conductive layer 1323. An external cable may be connected to the conductive layer 1323 to be electrically connected to the circuit board 120 through the conductive layer 1323. The connecting portion 131 is electrically connected to the ground layer 1321 as a ground portion of the cable connector 130. As shown in FIG. 1B, a plurality of pins 133 are connected to the connecting portion 131 and extend through the circuit board 120 to the lower surface 120b of the circuit board 120 to be electrically connected to the line on the lower surface 120b of the circuit board 120. (not shown). In addition, the pins 133 can be fixed to the lower surface 120b of the circuit board 120 by soldering.

As shown in Fig. 1B, the joint portion 132 protrudes from the casing 110 so as to be connected to an external cable. For example, the lower case 112 includes a uniform hole 112a through which the joint portion 132 of the cable joint 130 is passed to protrude from the casing 110. In addition, the outer dimension of the fixing member 140 is smaller than the inner dimension of the through hole 112a. Thus, even if the shielding member 160 is located inside the casing 110, the fixing member 140 can enter the casing 110 from the outside of the casing 110 through the through hole 112a. To fix the shielding element 160.

As shown in FIGS. 1A and 1B, the joint portion 132 has an external thread 1324, and the fixing member 140 is, for example, a nut. The fixing member 140 can be screwed with the external thread 1324 to fix the shielding member 160, for example, the shielding member 160 is fixed between the stopper 150 and the fixing member 140. The stopper 150 is, for example, a nut, and thus, the two nuts can hold the shield member 160 therebetween and have a loosening effect. The use of a nut as the fixing member 140 can avoid the problem of the deterioration of the glue as compared with fixing the shielding member 160 with the adhesive.

The connecting portion 131 is connected to the circuit board 120 and has a front surface 131f and an upper surface 131u. The surface 131f is a surface of the connecting portion 131 adjacent to an outer cable 10, that is, facing the surface of the external cable 10 (in the +X direction). The upper surface 131u is a surface of the connecting portion 131 away from the circuit board 120, that is, the surface facing away from the circuit board 120. In this embodiment, the front surface 131f is disposed substantially perpendicular to the upper surface 131u. The shielding element 160 shields at least a portion of the front surface 131f, and more particularly at least a portion of the upper surface 131u, to reduce the packet loss rate of the broadband data processing device 100 in receiving packet data. As shown in FIG. 1B, the present embodiment is described by taking the shield member 160 as a whole for shielding the entire front surface 131f.

As shown in FIG. 1A, the shield member 160 has a through hole 160a through which the joint portion 132 can pass and protrude. As shown in Fig. 1B, the shield member 160 has a length L1 in the longitudinal direction Y, and the connecting portion 131 has a length L2 in the longitudinal direction Y, wherein the length L1 is substantially twice the length L2. Thus, the packet loss rate of the packet data received by the broadband data processing device 100 can be effectively reduced.

Further, the shield member 160 has a height H1 in the thickness direction Z, and the joint portion 131 has a height H2 in the thickness direction Z, wherein the height H1 is substantially at least one times the height H2. Thus, the packet loss rate of the packet data received by the broadband data processing device 100 can be effectively reduced.

Further, the material of the shield member 160 may include a conductive material such as copper or iron. The shielding member 160 may be a conductive paper or a conductive sheet, wherein the conductive paper is, for example, a copper foil paper, and the conductive sheet is, for example, an iron sheet or an iron sheet. If the thickness of the shield member 160 is thick, it can be formed by a stamping method. In assembly, the shield member 160 can be pre-positioned or fixed to the lower case 112, and then the circuit board 120 can be assembled to the lower case 112, and then the fixing member 140 can be locked to the joint portion 132 to fix the shield member 160. Alternatively, the fixing member 140 may be fixed to the shielding member 160, and then the circuit board 120 may be assembled to the lower casing 112.

2 is a cross-sectional view of a broadband data processing apparatus 200 in accordance with another embodiment of the present invention. The broadband data processing device 200 includes a housing 110, a circuit board 120, a cable connector 130, a fixture 140, and a shielding member 160. The broadband data processing device 200 of the present embodiment is similar to the aforementioned broadband data processing device 100, different Yes, the broadband data processing device 200 omits the stop 150.

As shown in FIG. 2, the front surface 131f of the connecting portion 131 of the cable connector 130 extends forward to protrude beyond the circuit board 120, so that the shield member 160 can contact the front surface 131f of the connecting portion 131 outside the circuit board 120, The shield member 160 can be prevented from interfering with the circuit board 120. Since the shielding member 160 is electrically connected to the ground layer of the cable connector 130 through the front surface 131f and shields the entire front surface 131f of the connecting portion 131, the packet loss rate of the broadband data processing device 200 when receiving the packet data can be reduced.

Referring to FIGS. 3A and 3B, FIG. 3A is a cross-sectional view of the broadband data processing apparatus 300 according to another embodiment of the present invention, and FIG. 3B is a diagram showing the appearance of the shielding element 360 of the broadband data processing apparatus 300 of FIG. 3A. Figure.

The broadband data processing device 300 includes a housing 110, a circuit board 120, a cable connector 130, a fixture 140, and a shielding member 360. The broadband data processing device 300 of the present embodiment is similar to the aforementioned broadband data processing device 100, except for the structure of the shield member 360.

The shielding member 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 can be similar to the aforementioned shielding member 160. The front shielding portion 361 directly contacts the front surface 131f of the connecting portion 131. The upper shielding portion 362 and the lower shielding portion 363 are respectively connected to the upper and lower edges of the front shielding portion 361, and respectively extend to the upper surface 131u of the connecting portion 131 of the cable connector 130 and the lower surface 120b of the circuit board 120 to respectively The upper surface 131u of the connection portion 131 and the lower surface 120b of the circuit board 120 are shielded. As shown in FIG. 3A, the lower shielding portion 363 shields the cable The distribution range of the plurality of pins 133 of the wire connector 130, and the upper shielding portion 362 shields the entire upper surface 131u of the connection portion 131 of the cable connector 130. In this way, the packet loss rate of the broadband data processing device 300 in receiving the packet data can be reduced.

In another embodiment, the shielding element 360 can omit one of the upper shielding portion 362 and the lower shielding portion 363, and the packet loss rate of the broadband data processing device 300 in receiving the packet data can still be reduced.

In summary, the broadband data processing apparatus of the embodiment of the present invention electrically connects the cable connector with a shielding component to reduce or even avoid external magnetic field or electric field interference to the cable connector. Thus, when the broadband data processing device receives the packet data, even if the human body touches the cable connector, the packet loss rate is not increased to maintain or improve the signal quality. According to the actual measurement, the packet loss rate of the conventional unshielded component wideband data processing device when receiving the packet data is about 0.002% to 4.857%. Since the broadband data processing apparatus of the embodiment of the present invention can protect the packet loss rate by about 0.002% to 0.34%, or even the packet loss rate, by the shielding element.
