DETAILED DESCRIPTION OF THE INVENTION

Referring to FIG. 1, a cable use tracking apparatus in accordance with an embodiment of the present invention includes switch modules 21, 22, 23, a detecting module 30, and a computer 40. The cable use tracking apparatus is used for determining the number of times that cables 11, 12, and 13 are used in connecting with electronic devices (not shown).

The cable 11, 12, 13 includes a rectangular base 111, 121, 131 and a connecting member 112, 122, 132 extending up from the base 111, 121, 131. When the cables 11, 12, and 13 are used for connecting testing devices with the electronic devices under test, the connecting members 112, 122, and 132 of the cables 11, 12, and 13 are respectively plugged in sockets of the electronic devices. When testing is done, the connecting members 112, 122, and 132 are respectively pulled out of the sockets of the electronic devices.

The switch modules 21, 22, 23 can be button switches. The switch modules 21, 22, 23 include rectangular shaped main bodies 211, 221, 231 and buttons 212, 222, 232 respectively protruding from upper surfaces of the main bodies 211, 221, 231. Each switch module 21, 22, 23 includes a first contact and a second contact therein. The main bodies 211, 221, 231 of the switch modules 21, 22, 23 are respectively fixed to sides of the bases 111, 121, 131, with upper surfaces of the main bodies 211, 221, 231 respectively be on a same level with upper surfaces of the bases 111, 121, 131.

The detecting module 30 includes a microprocessor 31 for communicating with the switch modules 21, 22, 23, and an interface circuit 32 for converting signals from the microprocessor 31 to signals that can be used by the computer 40. First contacts of the switch modules 21, 22, 23 are respectively connected to ports P1.0, P1.1, P1.2 of the microprocessor 31. Second contacts of the switch modules 21, 22, 23 are connected to ground port GND of the microprocessor 31. Ports TXD, RXD, Vcc of the microprocessor 31 are connected to the interface circuit 32.

FIG. 2 and FIG. 3 are respectively schematic diagrams of the cable 11 before it is plugged in a socket 51 of an electronic device 50 and after it is plugged in the socket 51. After the cable 11 is plugged in the socket 51, the switch module 21 is pressed by a surface 52 adjacent to the socket 51. The switch module 21 thus turns on. The P1.0 of the microprocessor 31 is connected to ground. Therefore, the level state of the port P1.0 of the microprocessor 31 changes.

Likewise, after the cables 12, 13 are plugged in corresponding sockets, the switch modules 22, 23 turn on. The detecting module 30 detects the switching of states of the switch modules 21, 22, 23, and outputting result indicating signals to the computer 40. The computer 40 includes a processing module, for receiving the indicating signals, and counting the number of times that the cables 11, 12, 13 are used based on the indicating signals, for example, the number of times that the cable 11 is used is increased by 1 when the P1.0 of the microprocessor 31 is connected to ground once, and a monitor for displaying the number of times. When the number of times are known, the user can determine whether the cables 11, 12, 13 need to be changed or not, by comparing the number of times with the operating life of the cables 11, 12, 13. Further, when the cables 11, 12, 13 are broken, the user can evaluate the quality of the cables 11, 12, 13 based on the corresponding number of times that the cables 11, 12, 13 have been used.

The embodiment was chosen and described in order to explain the principles of the invention and their practical application so as to enable others skilled in the art to utilize the invention and various embodiments and with various modifications as are suited to the particular use contemplated.
