Transmission cable for a computer and an electronic device

Description

BACKGROUND

1. Technical Field

The present disclosure relates to a transmission cable providing communication between a computer and an electronic device.

2. Description of Related Art

A D-sub connector is often used for RS-232 serial communications, attached to a transmission cable, providing communication between a computer and an electronic device during a testing procedure. The D-sub connector includes a data receiving socket and a data transmission socket on specific locations of the D-sub connector.

A commonly used electronic device includes a data receiving pin and data transmission pin. The communication is effective when the data receiving socket electronically connects with the data transmission pin, and the data transmission socket electronically connects with the data receiving pin. If the data transmission pin and the data receiving pin of the electronic device do not correspond to the data receiving socket and the data transmission socket of the D-sub connector in connection, the communication between the electronic device and D-sub connector will be ineffective.

Therefore, there is room for improvement within the art.

DETAILED DESCRIPTION

FIG. 1 is a perspective view of a transmission cable 10 used with an electronic device 400. The transmission cable 10 includes a first plug 13 and a second plug 11. The first plug 13 includes a data receiving socket 131, a grounding socket 132, and a data transmission socket 133 arranged in a straight line. The grounding socket 132 is positioned between the receiving socket 131 and the data transmission socket 133, such that the data receiving socket 131 and the data transmission socket 133 keeps a same interval with respect to the grounding socket 132. In the exemplary embodiment, the second plug 11 is a D-sub connector for RS-232 serial communication. The second plug 11 includes a data receiving lead 112, a data transmission lead 113, and a grounding lead 115. The receiving socket 131 connects with the data receiving lead 112. The grounding socket 132 connects with the grounding lead 115. The data transmission socket 133 connects with the data transmission lead 113.

The transmission cable 10 is capable of connecting with an electronic device 400. The electronic device 400 may include a pin set 20 operable to connect with the transmission cable 10 for testing in a factory. The pin set 20 includes a first pin 21, a grounding pin 22, and a second pin 23. The grounding pin 22 is positioned between the first pin 21 and the second pin 23. The transmission cable 10 connects with the electronic device 400 by the first plug 13 receiving the pin set 20.

FIG. 2 is a block diagram of an electronic connection 100 established by the transmission cable 10 in a first state. A computer 300 may be in communication with the electronic device 400 through the electronic connection 100. The computer 300 includes a Data Carrier Detect (DCD) node DCD′, a data receiving node Rx′, a data transmission node Tx′, a Data Terminal Ready (DTR) node DTR′, a grounding node GND′, a Data Set Ready (DSR) node DSR′, a Request to Send (RTS) node RTS′, a Clear to Send (CTS) node CTS′, and a Ring Indicator (RI) node RI′.

The second plug 11 further includes a DCD lead 111, a DTR lead 114, a DSR lead 116, a RTS lead 117, a CTS lead 118, and a RI lead 119. The DCD lead 111 electronically connects with the DCD node DCD′. The data receiving lead 112 electronically connects with the data receiving node Rx′. The data transmission lead 113 electronically connects with the data transmission node Tx′. The DTR lead 114 electronically connects with the DTR node DTR′. The grounding lead 115 electronically connects with the grounding node GND′. The DSR lead 116 electronically connects with the DSR node DSR′. The RTS lead 117 electronically connects with the RTS node RTS′. The CTS lead 118 electronically connects with the CTS node CTS′. The RI lead 119 electronically connects with the RI node RI′.

The electronic device 400 further includes a data receiving node Rx, a grounding node GND, and a data transmission node Tx. In the exemplary embodiment, the first pin 21 electronically connects with the data receiving node Rx, the grounding pin 22 electronically connects with the grounding node GND, and the second pin 23 electronically connects with the data transmission node Tx. The first plug 13 may be operated to have the receiving socket 131 receive the second pin 23, the grounding socket 132 receive the grounding pin 22, and the data transmission socket 133 receive the first pin 21. The receiving socket 131 may electronically connect with the data transmission node Tx through the second pin 23. The data transmission socket 133 may electronically connect with the data receiving node Rx through the first pin 21. As a result, the electronic connection 100 is effective, and therefore the computer 300 may be in communication with the electronic device 400.

FIG. 3 is a block diagram of the electronic connection 100 established by the transmission cable 10 in a second state. The computer 300 may be in communication with an electronic device 400′ through the electronic connection 100. The electronic device 400′ also includes the pin set 20, the data receiving node Rx, the grounding node GND, and the data transmission node Tx. Differing from the electronic device 400, an arrangement of the data receiving node Rx and the data transmission node Tx of the electronic device 400′ is opposite to those of the electronic device 400.

In the exemplary embodiment, the first pin 21 electronically connects with the data transmission node Tx, the grounding pin 22 electronically connects with the grounding node GND, and the second pin 23 electronically connects with the data receiving node Rx. Differing from FIG. 2, the first plug 13 may be reversed to have the receiving socket 131 receive the first pin 21, the grounding socket 132 receive the grounding pin 22, and the data transmission socket 133 receive the second pin 23. The receiving socket 131 may electronically connect with the data transmission node Tx through the first pin 21. The data transmission socket 133 may electronically connect with the data receiving node Rx through the second pin 23. As a result, the electronic connection 100 is effective, and therefore the computer 300 may be in communication with the electronic device 400′.

It is to be further understood that even though numerous characteristics and advantages of the present embodiments have been set forth in the foregoing description, together with details of structures and functions of various 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 present invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
