技术领域 technical field
本实用新型涉及一种检测工装,特别是一种用于检测穿串行数据插头的检测工装。 The utility model relates to a detection tool, in particular to a detection tool for detecting a serial data plug.
背景技术 Background technique
串行接口简称串口,也称串行通信接口,是采用串行通信方式的扩展接口。串行接口的通信是指数据一位位地顺序传送,其特点是通信线路简单,只要一对传输线就可以实现双向通信。串行通信的两种最基本方式时同步串行通信方式和异步串行通信方式,串行接口按电气标准分为RS232、RS422和RS485,其中RS232是一种最为常用的串行通信接口,也成为标准串口。RS232电缆的两端各接一个数据接头,其中一个数据接头为公头,即DB9针式数据插头;另一个数据接头为母头,即DB9孔式数据插座。另外,目前应用较多的数据接口还有一种RJ45网口。 The serial interface is referred to as the serial port, also known as the serial communication interface, which is an extended interface that adopts the serial communication method. The communication of the serial interface refers to the sequential transmission of data bit by bit, and its characteristic is that the communication line is simple, as long as a pair of transmission lines can realize two-way communication. The two most basic methods of serial communication are synchronous serial communication and asynchronous serial communication. The serial interface is divided into RS232, RS422 and RS485 according to electrical standards, among which RS232 is the most commonly used serial communication interface. Become a standard serial port. Both ends of the RS232 cable are connected with a data connector, one of which is male, namely DB9 pin data plug; the other data connector is female, namely DB9 hole data socket. In addition, there is also an RJ45 network port that is currently used more data interfaces.
RS232的数据接头有时需要单独使用,因此必须保证每个插头的完好,才能保证使用RS232数据接头的设备工作正常。RS232数据接头的检测通常采用万用表进行检测,检测时,将万用表打到直流档,用红表笔和黑表笔分别连接两个孔或者两个针进行检测。对于孔式数据插座,由于其接口处都为孔式,直接将红表笔和黑表笔插入孔中即可进行检测,比较方便;而对于针式数据插头,检测时则需要将红表笔和黑表笔的表针与数据插头上的针相对才能检测,但是由于针式数据插头中各个针距离较近,表笔与针的接触时容易短路,检测不准确,工作效率较低。同样RJ45网口在检测时也存在同样的问题。 The RS232 data connector sometimes needs to be used separately, so each plug must be in good condition to ensure that the equipment using the RS232 data connector works normally. The detection of the RS232 data connector is usually carried out with a multimeter. When testing, turn the multimeter to the DC gear, and use a red test lead and a black test lead to connect two holes or two needles for detection. For hole-type data sockets, since the interfaces are all hole-type, it is more convenient to directly insert the red and black test leads into the holes; for pin-type data plugs, it is necessary to insert the red and black test leads into the holes for testing. However, due to the close distance between the needles in the pin-type data plug, it is easy to short-circuit when the test pen and the needle are in contact, the detection is inaccurate, and the work efficiency is low. The RJ45 network port also has the same problem during detection.
