Abstract
Disclosed is a wire clamping mechanism for a terminal. The wire clamping mechanism comprises two elastic clamping sheets for clamping a wire, wherein the two elastic clamping sheets are arranged in an overlaid manner and are connected through an elastic part; wire holes for allowing the wire to be inserted are formed in the two elastic clamping sheets respectively; and the elastic part enables the two elastic clamping sheets to generate shearing force of opposite directions on the wire in the wire holes. When the wire clamping mechanism is in use, the two elastic clamping sheets are pressed; the two overlaid elastic clamping sheets are moved oppositely in a staggered manner; the wire holes in the two elastic clamping sheets are overlaid; after the wire is inserted in the wire holes, the elastic clamping sheets are loosened; the elastic clamping sheets move in a direction perpendicular to the wire under the effect of elasticity, namely, the elastic clamping sheets are reset; and the two elastic clamping sheets generate the shearing force of opposite directions on the wire in the wire holes so as to tightly clamp the wire and to prevent the wire from being loosened.
