Description of the embodiments
The connecting terminal of the disconnecting link switch shown in fig. 1-4 comprises a clamping seat 1, a connecting frame 2 and a connecting screw 3, wherein the disconnecting link switch comprises a base 4, and the connecting terminal is arranged at an output position and an input position of the base 4 according to actual conditions. The bottom surface of holder 1 is to integrative extension connection of one side have a lug 5, and the activity is inserted in locating in the terminal frame 2 on the lug 5, still alternate in the terminal frame 2 to be provided with end clamp plate 6, and end clamp plate 6 laminating holder 1 bottom surface and the shape of lug 5 bottom surface to end clamp plate 6 stacks in the below of holder 1 and lug 5. The width of the bottom pressing plate 6 is basically consistent with the bottom surface of the clamping seat 1 and the wiring lug 5, the length of the bottom pressing plate 6 is equal to the length of the bottom surface of the clamping seat 1 and the length of the wiring lug 5, so that the bottom pressing plate 6 is basically arranged in a stacked mode along the bottom surface of the clamping seat 1 and the bottom surface of the wiring lug 5, a double-layer structural form is formed, and compared with the arrangement of small reinforcing ribs in the prior art, the structural strength of the wiring position is effectively enhanced, the current carrying capacity is improved, and the temperature rise is facilitated to be reduced.
