Description

Technical Field

[0001] The utility model relates to the technical field of electronic testing equipment, in particular to a disconnecting test terminal and a disconnecting test device. Background Art

[0002] The circuits of electronic equipment often need to be disconnected for testing, such as testing the secondary circuit of a current transformer. During the disconnection test, the circuit often needs to be switched on and off, but repeated crimping of the terminals is not only cumbersome, but also easy to damage the terminals. Therefore, disconnection test terminals are often used in the testing of the secondary circuit of a current transformer.

[0003] The disconnect test terminal is to install two unconnected conductive parts on the base, and place a conductive slider between the two conductive parts. The conductive slider can change the contact state with the conductive parts by sliding along the conductive parts. When the conductive slider slides to the disconnection side, the conductive slider is close to one conductive part and is not connected with the other conductive part, and the disconnect test terminal is in the disconnection state; when the conductive slider slides to the connection side, the conductive slider contacts both conductive parts, the conductive slider can be connected with both conductive parts, and the disconnect test terminal is in the connection state.

[0004] like Fig.13 As shown, the current disconnect test terminal generally has a visual window 9 above the conductive member 10. During the test, the disconnection or opening of the disconnect test terminal is judged by visually observing the position of the conductive slider. However, this method can only roughly determine the position of the conductive slider, and cannot determine whether the disconnect test terminal is closed in place. In particular, when multiple disconnect test terminals are simultaneously arranged on the same terminal row of the disconnect test device, it is very easy to misjudge the disconnection state of the circuit and thus cause a fault; and when the conductive slider is in contact with both conductive members 10 and the conductive slider is not in contact with one of the conductive members 10, the circuit is unstable and is also prone to cause circuit failure.
