1. Technical Field
The present disclosure relates to electronic devices, more particularly to a connector assembly of an electronic device.
2. Description of Related Art
Connectors are used to connect a first component to a second component. Generally, the connector includes a contact, a terminal, an interface, and other conductors. In use, an USB connector is connected to a connector via a cable, and the connector is connected to a motherboard to communicate the USB connector with the motherboard. However, the USB connector is usually far away from the connector and a long cable needs to be used to connect the USB connector with the connector. Thus, a signal between the USB connector and the motherboard would be decreased because the signal is transmitted over the long cable. Therefore, there is room for improvement within the art.
Many aspects of the embodiments can be better understood with references to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
At least one first USB input/output connector 103 and a second USB input/output connector 101 are connected to the input/output device 100. In one embodiment, a number of the at least one first USB input/output connector 103 is two, and the two first USB input/output connectors 103 are USB 3.0 input/output connectors. The second USB input/output connector 101 is a USB 2.0 input/output connector.
A first cable 600 is connected to the first connector 200 and each of the two first USB input/output connectors 103. A second cable 700 is connected to the second connector 300 and the second USB input/output connector 102. The signal increasing connector 400 are connected to two of the first cables 600 to divide each of the two first cables 600 to a first portion 601 and a second portion 603. In one embodiment, a length of the first portion 601 is 110 mm. The first portion 601 is connected to the signal increasing connector 400 and the input/output device 100. The second portion 603 is connected to the signal increasing connector 400 and the first connector 200.
Each of the first cable 600 comprises a plastic jacket 610, a plurality of center cores 650, and a plurality of dielectric insulators 630 enclosing the plurality of center cores 650. The plurality of dielectric insulators 630 are received in the plastic jacket 610.
The signal increasing connector 400 comprises a signal increasing circuit board 11 and a shielding device 30. In one embodiment, the shielding device 30 is used to prevent the signal increasing circuit board 11 from electromagnetic interference and electrostatic discharge, and the plurality of center cores 650 are attached to the signal increasing circuit board 11 by soldering. A plurality of electronic components 112 (only two shown in
The shielding device 30 comprises a first insulating member 31, a copper foil 32, and a second insulating member 33. The first insulating member 31 is secured to the signal increasing circuit board 11 and enclosing the signal increasing circuit board 11. In one embodiment, the first insulating member 31 is polyethylene and is secured to the signal increasing circuit board 11 by injection molding. The copper coil 32 is secured to a dielectric insulators 132 and located between the first insulating member 31 and the second insulating member 33. In one embodiment, the copper coil 32 is secured to the dielectric insulators 132 by soldering. The second insulating member 33 encloses the copper coil 32 to insulate the signal increasing circuit board 11. In one embodiment, after the first insulating member 31 and the signal increasing circuit board 11 are secured together, the second insulating member 33 is secured to the first insulating member 31 by injection molding. The second insulating member 33 is thermoplastic rubber. In one embodiment, a cross-section of the first insulating member 31 is substantially a rectangle, and the second insulating member 33 is substantially a rectangle.
In use, the signal increasing circuit board 11 is enclosed by the copper foil 32, so that the signal increasing circuit board 11 can be protected from disturbing by false signals from the outside of the signal increasing circuit board 11 or the inside of the signal increasing circuit board 11. The copper foil 32 is connected to the plurality of dielectric insulators 630, so that the copper foil 32 can be for ground. Therefore, the false signal from the outside of the signal increasing circuit board 11 or the inside of the signal increasing circuit board 11 can be transferred to the ground.
In addition, the first insulating member 31 and the second insulating member 33 are made by injection molding. The signal increasing circuit board 11 is protected by the first insulating member 31 and the second insulating member 33, so that each of the plurality of electronic components 112, the solder joint between each of the plurality of center cores 650, and the signal increasing circuit board 11 and the solder joint between the copper foil 32 and the plurality of dielectric insulators 630 can be protected well. The first insulating member 31 is substantially a rectangle, and the copper foil 32 can be easily enclosed on the first insulating member 31.
The signal increasing connector 400 is located between the first connector 200 and the input/output device 100, and the length of the first portion 601 is 100 mm. Therefore, the transmission signal between the input/output connector 100 and the motherboard 500 cannot be decreased by the first cable 600.
It is to be understood, however, that even though numerous characteristics and advantages have been set forth in the foregoing description of embodiments, together with details of the structures and functions of the embodiments, the disclosure is illustrative only and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
