As shown in fig. 4, in some embodiments, the face of the magnetic member 3 facing away from the mounting slot 22 is coplanar with the test face 21, thereby allowing the test face 21 of the clip 2 to be easily connected to the device terminals without obstructing the device terminals. For example, the face of the magnetic element 3 facing away from the mounting groove 22 is planar.

In some embodiments, the plurality of clips 2 are provided, the plurality of clips 2 are circumferentially spaced on the conductor 1, the plurality of clips 2 define a clamping cavity, and the test face 21 of each clip 2 faces inward (of the clamping cavity). Specifically, the conductor 1 is a cylinder, and a plurality of clips 2 are circumferentially disposed at intervals at the end of the conductor 1 and adjacent to the outer surface of the conductor 1. The test surface 21 of each clip 2 constitutes the inner wall surface of the clip cavity. During operation, the corresponding electric test wire clamp 100 is selected according to the size of the terminal during test wiring, the equipment terminal stretches the clamping pieces 2 (the magnetic pieces 3), and the test wire is fixed on the terminal by utilizing the magnetic force of the magnetic pieces 3.
