Description

Technical Field

[0001] The utility model belongs to the technical field of aviation connecting line testing, and in particular relates to a general aviation connector cable testing device. Background Art

[0002] Aviation connectors are widely used in the military field and also shine in the civilian industry due to their large number of connections, high reliability, good stability and easy installation. However, aviation connectors have a large number of connections and require the position and order of the pins, which leads to higher industrial requirements for their production than other ordinary connectors.

[0003] Traditionally, after the aviation connector cable is manufactured, each pin and each foot is tested using the resistance range of a multimeter, and the disconnected resistance value is used to determine whether the aviation connector cable is in the wrong sequence and whether the line resistance is synchronized. The more lines inside the cable, the more difficult it is to detect, and the easier it is to confuse the line sequence. This measurement method not only takes a long time to test, but also easily confuses the line sequence, resulting in signal dislocation and disconnection problems, and is prone to inexplicable failures or even signal loss when applied to the device;

[0004] Therefore, the utility model provides a general aviation connector cable testing device which can quickly test the aviation connector cable after the aviation connector is manufactured. Utility Model Content

[0005] The purpose of the utility model is to provide a general aviation connector cable testing device to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] The first terminal block includes a plurality of first connection terminals respectively connected in series with the aviation connector socket through first wires, and short-circuit pieces respectively connected in series with the plurality of first connection terminals, and a first conductive line connected in parallel with the output end of the short-circuit piece is connected to the negative electrode of the power supply compartment;

[0009] The second terminal block includes a plurality of second connection terminals respectively connected in series with the aviation connector plug through second wires, and a rocker switch respectively connected in series with the plurality of second connection terminals;

[0010] The second conductive wires connected in parallel at the output ends of the boat-shaped switches are connected to the positive pole of the power supply compartment, and each of the boat-shaped switches is correspondingly connected to a short-circuit piece to form a detection loop.

[0011] Furthermore, the power supply compartment is provided with a battery for supplying power to the first terminal block and the second terminal block to generate a detection circuit. Two No. 5 batteries can be placed in the power supply compartment according to test needs. The two No. 5 batteries cooperate with the power supply compartment to supply power to the detection circuit formed by the first terminal block and the second terminal block.

[0012] Furthermore, each of the short-circuit pieces is provided with an LED lamp bead, and an identification area for identifying the position of the short-circuit piece is provided on one side of the short-circuit piece corresponding to the LED lamp bead. By toggling each boat-type switch to control the lighting of the corresponding LED lamp bead in series, it is determined whether the circuit of the aviation connector cable under test can conduct current. If the pins on the aviation connector are well connected to its connecting wires, the LED lamp bead will light up and go out normally under the control of the boat-type switch. If the LED lamp bead does not respond when the boat-type switch is toggled, it means that this pin of the aviation connector cable has poor contact or the cable has a broken wire problem. The identification area is used to identify the order in which the LED lamp beads run, so as to determine whether there is a line sequence error in the tested aviation connector cable during the test.

[0013] Furthermore, the aviation connector socket is fixed by the assembly shell and is arranged on the outer wall of the assembly shell, the aviation connector plug is arranged on the outside of the assembly shell through the second wire, and the aviation connector socket and the aviation connector plug are respectively connected to the connection ends of the aviation connector cable to be tested, and the aviation connector cable to be tested is respectively connected to the aviation connector socket and the aviation connector plug outside the assembly shell, forming a loop for detecting the aviation connector cable to be tested.

[0014] Furthermore, a plurality of second wires connected to the second wiring terminals and the aviation connector plug and arranged outside the assembly housing are wrapped with cable protective covers, and the cable protective covers are used to fix and protect the second wires extending out of the assembly housing.

[0015] The utility model has the following technical effects and advantages:

[0016] The general aviation connector cable testing equipment is connected to the aviation connector socket through a first terminal row, and the second terminal row is connected to the aviation connector plug. The first terminal row and the second terminal row are respectively connected to the negative electrode and the positive electrode of the power supply compartment. The aviation connector socket and the aviation connector plug are respectively connected to the aviation connector cable to be tested, so that a test loop is formed between the aviation cable to be tested and the aviation connector socket and the aviation connector plug. The shorting piece on the first terminal row is correspondingly controlled by the rocker switch on the second terminal row, and the LED lamp bead on the shorting piece is turned on and off to check whether the corresponding pins of the aviation connector cable have poor contact or the problem of internal cable breakage.

It has a simple testing principle for aviation connector lines and convenient operation. The test results are intuitive and easy to judge, and the fault can be located.

[0026] A battery 13 is provided in the power supply compartment 5 for supplying power to the first terminal row 2 and the second terminal row 4 to generate a detection circuit. Two No. 5 batteries can be placed in the power supply compartment 5 according to the needs of the test. The two No. 5 batteries cooperate with the power supply compartment 5 to supply power to the detection circuit formed by the first terminal row 2 and the second terminal row 4.

[0027] An LED lamp bead 14 is provided on each short-circuit 7, and an identification area 15 for identifying the position of the short-circuit 7 is provided on one side of the short-circuit 7 corresponding to the LED lamp bead 14. By toggling each rocker switch 11 to control the lighting of the corresponding LED lamp bead 14 in series, it is determined whether the circuit of the aviation connector cable under test can conduct current. If the pins on the aviation connector are well connected to its connecting wires, the LED lamp bead 14 will light up and go out normally under the control of the rocker switch 11. If the LED lamp bead 14 does not respond when the rocker switch 11 is toggled, it means that this pin of the aviation connector cable has poor contact or the cable is broken. The identification area 15 is used to identify the order in which the LED lamp bead 14 runs, so as to determine whether there is a line sequence error in the tested aviation connector cable during the test.

[0031] When testing the aviation connector cable after production, the two ends of the aviation connector cable to be tested are respectively plugged into the aviation connector plug 3 and the aviation connector socket 1, and the operator sequentially turns on and off the rocker switch 11 to control the corresponding LED lamp beads 14 in series, thereby judging whether the circuit of the aviation connector cable to be tested can conduct current.
