Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
As shown in fig. 1 to 4, the insulation cap of this embodiment includes a sleeve 1 and a clamping assembly 2, the sleeve 1 is a hollow cylinder with one open end, an end of a cable 100 can be inserted into the sleeve 1, the clamping assembly 2 is disposed on an outer wall of the sleeve 1, the clamping assembly 2 includes a mounting seat 21 and a clamp 22, connecting shaft 23 and elastic component 24, first through-hole 10 has been seted up on mount pad 21, anchor clamps 22 include chuck 221, clip tail 222 and connecting portion 223, the one end of chuck 221 and clip tail 222 all is connected with connecting portion 223, second through-hole 20 has been seted up on connecting portion 223, connecting shaft 24 passes first through-hole 10 and second through-hole 20, make anchor clamps 22 be connected with mount pad 21, anchor clamps 22 can rotate around connecting shaft 24, elastic component 23 sets up between the outer wall of sleeve 1 and clip tail 222, elastic component 23 can exert elasticity to clip tail 222, elasticity makes chuck 221 compress tightly the crust 110 of the cable 100 of plugging in the inside sleeve 1. When the end of the cable 100 is stripped of a portion of the jacket 110 to expose the conductors 120 for connection, the conductors 120 need to be wrapped or shielded to prevent inadvertent contact by personnel. The insulation cap of the embodiment utilizes the connecting shaft 24 to hinge the clamp 22 and the mounting seat 21, and then utilizes the elastic force of the elastic member 23 to generate a rotating torque on the clip tail 222, so that the clip 221 of the clamp 22 compresses the outer skin 110 of the cable 100, the reverse torque applied to the clip 221 by the outer skin 110 of the cable 100 is equal to the torque applied to the clip tail 222 by the elastic member 23, so that the clamp 22 is kept in a stable state, the sleeve 1 can stably cover the exposed conductor 120 of the cable 100, when the insulation cap needs to be disassembled, only the clip tail 222 needs to be pressed, the clip 221 is separated from the outer skin 110 of the cable 100 to be in contact with the outer skin 110 of the cable 100, the cable 100 can be drawn out of the sleeve 1, and the insulation cap can be repeatedly used and conveniently disassembled and disassembled.
