This open / short test device for simulating the actual application of a connector realizes the open and short circuit tests of the connector, can effectively test the correct number of pins and the number of circuits of the connector during the actual test process, solves the problem of unstable connector testing, and thus improves the test accuracy of the connector.
[0025] Combined with Figures 1 to 3 As shown, the open / short test device for simulating the actual application of a connector in this embodiment includes a test stage 10, a tongue portion 20, a first test portion 30, and a second test portion 40. The test stage 10 is provided with a positioning groove 11 for placing and positioning the connector. The tongue portion 20 can cooperate with the first test portion 30 to perform an open circuit test on the connector, and the second test portion 40 cooperates with the first test portion 30 to perform a high-voltage and short circuit test on the connector.
[0026] In this embodiment, the open / short test device for simulating the actual application of a connector further includes a frame 50, and the test stage 10, the tongue portion 20, the first test portion 30, and the second test portion 40 are all installed on the frame 50.
[0027] Furthermore, a number of positioning pins 60 are provided on the frame 50 to position the test stage 10. The presence of the positioning pins 60 can further position the test stage 10, thereby improving the positioning accuracy of the connector. And a control box 80 is provided on the frame 50 for overall control and information interaction. Control buttons 81 are provided on the control box 80 for easy operation by the operator.
[0028] Combined Figure 1 with Figure 3 As shown, the tongue portion 20 of this embodiment includes a tongue cylinder 21 and a protruding tongue 22. The tongue cylinder 21 drives the protruding tongue 22 to make contact with the contact spring piece of the connector. The first test portion 30 includes a first cylinder 31 and a first probe 32. The first cylinder 31 drives the first probe 32 close to the connector. The second test portion 40 includes a second cylinder 41 and a second probe 42. The second cylinder 41 drives the second probe 42 to conduct the connector. In actual test operations, the test steps are divided into two steps. In the first step, the first cylinder 31 of the first test portion 30 drives the first probe 32 close to the connector, and at the same time, the tongue cylinder 21 of the tongue portion 20 drives the protruding tongue 22 to move, so that the protruding tongue 22 contacts the contact spring piece of the connector to test and analyze whether there is an open circuit in the connector. In the second step, the tongue portion 20 resets, and the second cylinder 41 of the second test portion 40 drives the second probe 42 to move, so that each row of the connector forms a loop, thereby stably and effectively detecting the correct number of pins and the number of loops.
[0029] In this embodiment, the first probe 32 is connected to the first cylinder 31 through a first probe board 90, and the second probe 42 is connected to the second cylinder 41 through a second probe board 100.
[0030] Furthermore, a conductive block 70 is provided on the frame 50. After the second cylinder 41 drives the second probe 42 to contact the conductive block 70, the connector is conducted. The conductive block 70 of this embodiment is a stainless steel block.

[0031] In actual use of the open / short test device for simulating the actual connector application in this embodiment, after the connector is placed on the test stage 10 for positioning, the first cylinder 31 of the first test portion 30 drives the first probe 32 close to the connector, and at the same time, the tongue cylinder 21 of the tongue portion 20 drives the protruding tongue 22 to move, so that the protruding tongue 22 contacts the contact spring piece of the connector to test and analyze whether there is an open circuit in the connector. Then the tongue portion 20 resets, and the second cylinder 41 of the second test portion 40 drives the second probe 42 to move, so that each row of the connector forms a loop, thereby stably and effectively detecting the correct number of pins and the number of loops and completing the high-voltage and short-circuit tests of the connector.
