BACKGROUND OF THE INVENTION
Field of Invention
[0001] The present invention relates to a connector device, and more particularly, to an
RJ45 connector device having a key structure for changing pin definitions.
Related Art
[0002] Currently, with the rapid development of technologies, more and more products in
our daily life have developed from a conventional mechanical analogy control mode
into an electronic digital control mode. Thus, various electronic devices or electronic
elements are connected to each other through different types of connectors or connector
devices, thereby achieving the electrical connection effects. Among various connectors,
the common connectors include circular connectors, specification conversion connectors,
and so on. As for the connector devices, common connector devices include RJ45 connector
devices, USB connector devices, and so on.
[0003] As for each type of connectors or connector devices in a different specification,
the data read or received via the pins electrically connected to such connectors or
connector devices are constant. Thus, when a different data processing function is
required, another connector or connector device of a different specification needs
to be used, so as to read or receive corresponding data. However, since each type
of connectors or connector devices occupy certain space and volume, the more connectors
or connector devices are used, the larger space and volume are occupied, which violates
a current design concept for an electronic device of being light, thin, short, and
small.
[0004] Therefore, a single connector or connector device that can achieve functions of many
different types of connectors or connector devices is needed. In this way, since only
a single connector or connector device is employed, the volume and space occupied
by using many different connectors or connector devices can be saved, which not only
conforms to the design concept of being light, thin, short, and small, but also saves
the materials indirectly.
[0005] In view of the above problem in the prior art that various connector devices occupy
a lot of the available space of the electronic device when being used, it is necessary
to propose an improved technical means to solve such a problem.
SUMMARY OF THE INVENTION
[0006] In view of the problem in the prior art that various connector devices occupy a lot
of available space of an electronic device when being used, the present invention
is directed to an RJ45 connector device having a key structure for changing pin definitions.
[0007] The RJ45 connector device having a key structure for changing pin definitions provided
in the present invention includes a base, a conversion circuit board, a set of input
pins, a key circuit board, an information processing circuit board, and an output
circuit board.
[0008] The base has a recess and an accommodation space. A hole is disposed at a position
where the recess and the accommodation space are separated from each other. The conversion
circuit board is disposed in the accommodation space, and has a conversion processor
disposed thereon. The set of input pins are disposed within the recess and is electrically
connected to the conversion circuit board. The key circuit board is disposed in the
accommodation space, and has a key disposed thereon corresponding to the hole. The
key circuit board is electrically connected to the conversion circuit board. The information
processing circuit board is electrically connected to the conversion circuit board
and has an information processor disposed thereon. The output circuit board is electrically
connected to the information processing circuit board and has a set of output pins
disposed thereon.
[0009] When the key is pressed, a conversion signal is triggered; the conversion processor
converts a part of input information input by a designated input pin in the set of
input pins into relay information and transfers the relay information, the conversion
signal, and the input information into the information processor; and then the information
processor converts the input information and the relay information into output information
through designated processing according to the conversion signal, and transfers the
output information to be output via the set of output pins.
[0010] The system and method according to the present invention have been described above.
The difference between the present invention and the prior art lies in that, the RJ45
connector device of the present invention includes a conversion circuit board, a key
circuit board, an information processing circuit board, and an output circuit board,
and when a key on the key circuit board is pressed to trigger a conversion signal,
a conversion processor disposed on the conversion circuit board first converts a part
of input information input by a designated input pin in the set of input pins into
relay information, and then transfers the relay information, the conversion signal,
and the input information to the information processor; and the information processor
then converts the input information input by the set of input pins and the relay information
into output information through designated processing according to the conversion
signal, and outputs the output information after being processed by the conversion
processor for being output via the set of output pins, so as to switch different pin
definitions on a single RJ45 connector device, thereby achieving an effect of a multi-functional
connector device.
[0011] With the above technical means, the present invention can save the available space
of the electronic device and enable a single connector device to achieve technical
effects of a multi-functional connector device in terms of switching pin definitions.

DETAILED DESCRIPTION OF THE INVENTION
[0013] The detailed features and advantages of the present invention will be described in
detail in the following embodiments. Those skilled in the arts can easily understand
and implement the content of the present invention. Furthermore, the relative objectives
and advantages of the present invention are apparent to those skilled in the arts
with reference to the content disclosed in the specification, claims, and drawings.
[0014] An RJ45 connector device having a key structure for changing pin definitions of the
present invention is described below. FIG. 1 is a three-dimensional exploded view
of an RJ45 connector device having a key structure for changing pin definitions according
to the present invention. FIG. 2 is a three-dimensional view of a base of an RJ45
connector device having a key structure for changing pin definitions according to
the present invention.
[0015] The RJ45 connector device having the key structure to change the pin definition according
to the present invention includes a base 10, a conversion circuit board 20, a set
of input pins 30, a key circuit board 40, an information processing circuit board
50, and an output circuit board 60.
[0016] The base 10 is formed with a recess 11 and an accommodation space 12 through injection
molding. The accommodation space 12 (shown in FIG. 2) is used for accommodating the
conversion circuit board 20 and the key circuit board 40. A hole 13 (shown in FIG.
2) is disposed at a position where the recess 11 and the accommodation space 12 are
separated from each other.
[0017] The base 10 may be made of polyphthalamide (PPA) or other thermoplastic resins commonly
used for manufacturing the base 10 of the connector device. The base 10 further has
at least one positioning element 14, which is used to fix the RJ45 connector device
to an external circuit board (not shown) in the electronic device. The base 10 can
be fixed to the external circuit board accurately and rapidly by using the relative
positions between the positioning elements 14.
[0018] In addition, the RJ45 connector device further includes a housing 15 made of a metal
or thermoplastic resin. The housing 15 is used for enclosing the base 10 externally.
The housing 15 further has at least one positioning part 151. When the RJ45 connector
device is disposed on the housing of the electronic device (not shown), the positioning
part 151 on the housing 15 of the RJ45 connector device may be used for positioning.
[0019] Next, the conversion circuit board 20 is disposed in the accommodation space 12,
and has a conversion processor 21 disposed thereon. The conversion processor 21 is
used to perform calculations on a part of input information received by the RJ45 connector
device, and convert the input information into relay information. The input information
is received from an external electronic device. The information conversion process
of the conversion processor 21 will be illustrated below in detail.
[0020] Then, the set of input pins 30 are disposed in the recess 11. The set of input pins
30 may be directly buried in the base 10 while the base 10 is injection molded. Alternatively,
the set of input pins 30 are disposed in the recess 11 after the base 10 has been
injection molded. Then, a cover plate 31 covers the set of input pins 30 (such a connection
manner is depicted in the drawing, but the present invention is not limited thereto),
so that the set of input pins 30 are electrically connected to the external RJ45 connector
device. The set of input pins 30 are electrically connected the conversion circuit
board 20, so that the conversion processor 21 disposed on the conversion circuit board
20 can receive the input information.
[0021] Considering the manner of disposing the set of input pins 30 within the recess 11
through the cover plate 31, a cover front edge 311 of the cover plate 31 is fitted
with an inside shape of a pin front edge 301 of the set of input pins 30, and a bottom
surface of the cover plate 31 is fitted with a shape of the set of input pins 30.
Then, the cover front edge 311 of the cover plate 31 is in contact with an interior
of the pin front edge 301 of the set of input pins 30 at an inclination angle. Then,
the cover plate 31 is rotated to make the bottom surface of the cover plate 31 in
contact with the set of input pins 30, so that the set of input pins 30 can be disposed
within the recess 11, and thus the set of input pins 30 are buried within the base
10 through the cover plate 31.
[0022] In addition to the conversion circuit board 20, the key circuit board 40 is also
disposed in the accommodation space 12 of the base 10. The conversion circuit board
20 is electrically connected to the key circuit board 40, the information processing
circuit board 50, and the output circuit board 60 respectively. The information processing
circuit board 50 and the conversion circuit board 20 are electrically connected to
each other through a set of conversion pins 70. The output circuit board 60 and the
information processing circuit board 50 are electrically connected to each other through
a set of output pins 61. Therefore, information can be transferred among the different
circuit boards.
[0023] A key 41 is disposed on the key circuit board 40 and is arranged at a position corresponding
to the hole 13 at the poison of the base 10 where the recess 11 and the accommodation
space 12 are separated from each other. Thus, the key 41 on the key circuit board
40 may be pressed through the recess 11 via the hole 13.
[0024] At least one light-emitting diode (LED) 42 may be further disposed on the key circuit
board 40. As the key circuit board 40 and the conversion circuit board 20 are electrically
connected to each other, a color shown by the LEDs 42 may be controlled by the conversion
processor 21 on the conversion circuit board 20. The pin definitions of the RJ45 connector
device may correspond to the colors shown by the LEDs 42. One LED can present more
than two colors. Through different variations and combinations of colors presented
by the LEDs 42, the pin definitions of the RJ45 connector device can be shown.
[0025] An information processor 51 is disposed on the information processing circuit board
50. The information processor 51 is used for performing designated processing on the
relay information generated after a part of input information received by the RJ45
connector device is processed by the conversion processor 21 and the input information
received by the RJ45 connector device according to different conversion signals and
converting the relay information and the input information into output information.
[0026] The set of output pins 61 are disposed on the output circuit board 60. After the
information processor 51 performs computation operations on the relay information
and the input information and converts them into the output information, the output
information obtained by the information processor 51 may be output via the set of
output pins 61 on the output circuit board 60. Furthermore, the set of output pins
61 on the output circuit board 60 are also used for electrically connecting to an
external circuit board, so that the external circuit board can receive the processed
output information of the RJ45 connector device.
[0027] The RJ45 connector device after being assembled is shown in FIG. 3. FIG. 3 is a three-dimensional
assembly view of an RJ45 connector device having a key structure for changing pin
definitions according to the present invention.
[0028] FIG. 4A is a schematic circuit diagram for information processing by a conversion
processor in an RJ45 connector device having a key structure for changing pin definitions
according to the present invention.
[0029] Referring to FIGs. 1 and 4A, in the RJ45 connector device, four pins (TX+, TX-, RX+,
and RX-) in the set of input pins 30 are electrically connected to four designated
pins of the conversion processor 21 on the conversion circuit board 20 directly. The
conversion processor 21 converts a part of the input information received via the
four designated pins through a conversion circuit 80.
[0030] As shown in the figures, a first transformer element 81, a second transformer element
82, a first sensing element 83, a second sensing element 84, a third sensing element
85, and a fourth sensing element 86 are used in the conversion circuit 80. Based on
the circuit shown in FIG. 4A, the four input information TX+, TX-, RX+, and RX- in
the set of input pins 30 are converted into six output signals, namely, TD+, TD-,
CT, RD+, RD-, and CT, through the conversion circuit 80. The six output signals are
the relay information. The relay information is then transferred into the information
processor 51.
[0031] FIG. 4B is a schematic block diagram of an information processing function of an
information processor in an RJ45 connector device having a key structure for changing
pin definitions according to the present invention.
[0032] Referring to FIG. 1 and FIG. 4B, the information processor 51 receives the relay
information (TD+, TD-, CT, RD+, RD-, and CT, referring to FIG. 4A) output from the
conversion processor 21 and the input information of the other pins in the set of
input pins 30 through a receive module 511. The receive module 511 transfers the received
relay information and input information to a conversion module 512. For example, since
the present invention uses an RJ45 connector device, the receive module 511 may be
an Ethernet port.
[0033] The conversion module 512 converts the relay information and the input information
into internal information that can be used by an access control module 513. For example,
the conversion module 512 may be a physical layer (PHY), and the access control module
513 may be a media access control (MAC) layer, which are both communication elements
defined by standards, and will not be described here.
[0034] Next, a central processing unit (CPU) 514 performs designated processing on the internal
information sequentially through the access control module 513. The CPU 514 divides
the internal information into serial information and relay output information, and
outputs the serial information via a serial port 515, and outputs the relay output
information via an input/output (I/O) port 516.
[0035] The serial information output via the serial port 515 are TX, RX, RTS, and CTS of
the RS232 signal, and the relay output information output via the I/O port 516 are
VCC, GND, Reset, and DIO. These eight outputs are the output information, and may
be output via the set of output pins 61. When the RJ45 connector device is electrically
connected to the external circuit board, the subsequent data processing may be performed
according to the pins defined by the set of output pins 61 and the output information.
[0036] In conclusion, when the key 41 on the key circuit board 40 is pressed to trigger
the conversion signal, the conversion processor 21 first converts a part of the input
information into the relay information, and transfers the relay information to the
information processor 51. Then, the information processor 51 performs designated processing
on the input information input by the set of input pins 30 and the relay information
according to the conversion signal, converts the input information and the relay information
into designated output information, and transfers the output information for being
output via the set of output pins 61, thereby achieving the effect of switching different
pin definitions with a single RJ45 connector device, and meanwhile achieving the technical
effects of a multi-functional connector device.
[0037] The implementation aspect in the drawings is merely intended for demonstration, but
not to limit the applications of the present invention. Any conversion circuit that
can achieve a similar function should fall within the scope of the present invention.
[0038] To sum up, the difference between the present invention and the prior art lies in
that, the RJ45 connector device of the present invention includes a conversion circuit
board, a key circuit board, an information processing circuit board, and an output
circuit board, and when a key on the key circuit board is pressed to trigger a conversion
signal, a conversion processor disposed on the conversion circuit board first converts
a part of input information input by a designated input pin in the set of input pins
into relay information, and then transfers the relay information, the conversion signal,
and the input information to the information processor; and the information processor
then converts the input information input by the set of input pins and the relay information
into output information through designated processing according to the conversion
signal, and outputs the output information after being processed by the conversion
processor for being output via the set of output pins, so as to switch different pin
definitions on a single RJ45 connector device, thereby achieving an effect of a multi-functional
connector device.
[0039] With the above technical means, the present invention can save the available space
of the electronic device and enable a single connector device to achieve technical
effects of a multi-functional connector device in terms of switching pin definitions.
