Abstract
The utility model relates to a test connecting device used to connect a notebook computer and a PCM communication device, and particularly relates to a USB conversion 232 test serial port. The USB conversion 232 test serial port comprises a housing, a USB/232 interface sub port is disposed in the housing, a USB spigot extends out of the housing, a 232 interface female port is plugged into a 232 interface sub port of the USB/232 interface sub port , a second pin head, a third pin head and a fifth pin head of the 232 interface female port are respectively connected with one end of an RX signal line, one end of a TX signal line and one end of a GND signal line, the other end of the RX signal line and the other end of the TX signal line are connected with a positive plug, the other end of the GND signal line is connected with a negative plug, and the positive plug and the negative plug both extend out of the housing. When the USB conversion 232 test serial port is used, the USB spigot is plugged into the notebook computer, the positive plug is plugged into a test positive jack of the PCM communication device, and the negative plug is plugged into a test negative plug of the PCM communication device, so test wiring of the PCM communication device is completed; and the test serial port provides great convenience for on-site testing of the PCM communication device, and working efficiency is improved.
Description
Technical field
The utility model relates to for connecting the test connecting apparatus of notebook computer and PCM communication equipment, is specially a kind of USB conversion 232 test serial ports.
Background technology
When PCM communication equipment overhauls 232 passage, need to connect computer, by computer, test.While testing at the scene, for convenient, tester carrying notebook computer tests, but there is no com port on present notebook computer, when notebook computer is connected with PCM communication equipment, all by USB/232 interface joint connection in site, after testing, just take out stitches, when test next time by the time, rewiring again, time and effort consuming, very inconvenient.
Summary of the invention
When the utility model carries out site examining and repairing in order to solve PCM communication equipment, need the problem of field connection, a kind of USB conversion 232 test serial ports are provided.
The utility model is to adopt following technical scheme to realize: a kind of USB conversion 232 test serial ports, comprise housing, in housing, be provided with USB/232 interface rim of the mouth, and USB socket stretches out housing, on the 232 interface rims of the mouth in USB/232 interface rim of the mouth, be inserted with female mouthful, 232 interfaces, on the 2nd syringe needle, the 3rd syringe needle and the 5th syringe needle that 232 interfaces are female mouthful, be connected with respectively RX holding wire, TX holding wire and GND holding wire, the other end of RX holding wire and TX holding wire is connected with positive plug, the other end of GND holding wire is connected with negative plug, and positive plug and negative plug all stretch out housing.
During use, positive plug inserts the positive jack of PCM communication equipment voice frequency distributing module, negative plug inserts the negative jack of PCM communication equipment voice frequency distributing module, complete the test wiring of PCM communication equipment, wherein RX holding wire and TX holding wire are respectively and receive holding wire and transmitted signal, and GND holding wire is earth connection; This test serial ports greatly facilitates the on-the-spot test of PCM communication equipment, has improved operating efficiency.
The utility model provides a kind of USB conversion 232 test serial ports, and this test serial ports greatly facilitates the on-the-spot test of PCM communication equipment, has improved operating efficiency.
