Description
Technical field
The utility model relates to a kind of detection frock, particularly a kind of detection frock for detection of wearing the serial data plug.
Background technology
Serial line interface is called for short serial ports, also claims serial communication interface, is the expansion interface that adopts serial communication mode.The communication of serial line interface refers to that more than ground orders of data transmit, and are characterized in that communication line is simple, as long as a pair of transmission line just can be realized two-way communication.Synchronous serial communication mode and asynchronous serial communication mode during two kinds of serial communication basic modes, serial line interface is divided into RS232, RS422 and RS485 by electrical standard, and wherein RS232 is a kind of serial communication interface the most commonly used, also becomes standard serial port.The two ends of RS232 cable respectively connect a data joint, and one of them data connector is male, i.e. DB9 pin type data pin; Another data connector is female, i.e. DB9 cellular type data socket.In addition, use at present more data-interface and also have a kind of RJ45 network interface.
The data connector of RS232 needs independent use sometimes, therefore must guarantee the intact of each plug, and guarantee uses the equipment of RS232 data connector working properly.The detection of RS232 data connector adopts multimeter to detect usually, during detection, multimeter is got to zero frequency span, respectively connects two holes or two pins detect with red test pencil and black meter pen.For the cellular type data socket, because its interface all is cellular type, directly red test pencil and black meter pen is inserted in the hole and can detect, more convenient; And for the pin type data pin, then need with the indicator of red test pencil and black meter pen and relative could the detection of pin on the data pin, but because each pin close together in the pin type data pin easy short circuit during the contacting of test pencil and pin during detection, detect inaccurately, work efficiency is lower.Also there is same problem in same RJ45 network interface when detecting.
The utility model content
The utility model technical issues that need to address provide a kind of convenient converter that detects the serial data plug, on the basis that guarantees Detection accuracy, greatly increase work efficiency.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is as follows.
Converter for detection of the serial data plug comprises insulating base, is embedded with several metallic cylinder in the insulating base, and the quantity of the quantity of metallic cylinder and serial data plug is corresponding; Also be provided with on the described insulating base and the corresponding data socket of serial data plug, corresponding and be electrically connected by wire one by one between the terminals in the data socket and the metallic cylinder.
Improvement of the present utility model is: the diameter of described metallic cylinder is 2 ± 0.5mm.
Further improvement of the utility model is: also be provided with detection module in the described insulating base, described detection module comprises battery, resistance, switch and two test sides that are connected in series successively, and two ends, described test side have been arranged in parallel voltage table.
Because the technical progress of having adopted technique scheme, the utility model to obtain is as follows.
The utility model is simple in structure, can conveniently detect the serial data plug, has guaranteed the accuracy rate that detects, and has improved work efficiency.During use, only need to be detected the pin type data pin and insert in the socket, red test pencil and black meter pen are inserted respectively in the pedestal get final product in the corresponding metallic cylinder.The diameter of metallic cylinder is set to 2mm, to make things convenient for test pencil to insert smoothly and to guarantee that contact is good.The detection module of the utility model setting can make testing process more convenient, need not to use multimeter, only needs the pin of needs detection and two test side short circuits of detection module are opened switch, can detect.

Fig. 2 is the circuit diagram of the utility model detection module.
Fig. 3 is the circuit diagram of embodiment 2.
Specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
The utility model is applied to detect RS232 pin type data pin, comprises insulating base, is provided with nine metallic cylinder, a DB9 cellular type data socket and a detection module in the insulating base.Metallic cylinder is embedded in the insulating base, and the cellular type data socket is fixed on a side of insulating base top end face, and detection module is embedded in the insulating base.The cellular type data socket is equipped mutually with the pin type data pin.
The annexation of metallic cylinder and cellular type data socket as shown in Figure 1.Connect one to one by wire between hole in the cellular type data socket and the metallic cylinder.Wire employing diameter is the outsourcing insulated hull annealed copper wire of 1mm in the present embodiment, and wire is connected between cellular type data socket and the metallic cylinder, and is welded on by welding manner on the bottom and metallic cylinder bottom in hole.Wire is embedded in the insulating base and does not expose, to guarantee the reliability of connection.Also in the upper surface of the insulating base position adjacent with metallic cylinder, mark has the pin sequence number corresponding with the pin of tested RS232 pin type data pin, such as 1 ~ 9 among the figure in the present embodiment.
The circuit diagram of detection module as shown in Figure 2, comprise battery E, resistance R, voltage table V, K switch and two test side S1, S2, battery E, resistance R, K switch and two test side S1, S2 are connected in series successively, voltage table is connected in parallel on the two ends of test side, for detection of the magnitude of voltage between tested RS232 pin type data pin pin.The test side is used for being connected with metallic cylinder by detection line, for detection of tested RS232 pin type data pin.
During the utility model work, at first tested RS232 pin type data pin is inserted in the cellular type data socket; Then the black detection line is inserted between test side S1 and the metallic cylinder 5, red detection line is inserted between test side S2 and the metallic cylinder 2; Open again switch S, when the voltage table reading when 5V is above, illustrate that tested RS232 pin type data pin interconnector is correct, this pin can normally use.
The same method detects the line situation between metallic cylinder 3 and the metallic cylinder 5, when the voltage table reading when 5V is above, this pin can normally use.Because the pin that RS232 pin type data pin mainly uses namely is 2,3,5, so after having detected above-mentioned steps, illustrates that tested RS232 pin type data pin interconnector is correct, can normally use.
Certainly, the utility model also can not use detection module, but uses in conjunction with multimeter.When using in conjunction with multimeter, adopt the zero frequency span of multimeter, red test pencil and the black meter pen of multimeter inserted respectively in the metallic cylinder, detect.
When the utility model is applied to detect RJ45 network interface formula data pin, to be embedded in the insulating base with the network interface seat that the network interface plug is equipped with mutually, each inserted sheet in the network interface seat passes through correspondingly connection metal cylinder lower end of wire, and the network interface seat is connected as shown in Figure 3 with metallic cylinder.During detection RJ45 network interface plug is inserted in the network interface seat, utilize the corresponding metallic cylinder of the corresponding TX of RJ45 terminal, RX and ground to detect, detection method is with the detection method that detects RS232 pin type data pin.
