[0057] like Fig.14 As shown, the insulating shield 11 wraps the entire wire clamp to ensure the overall insulation. The insulating shield 11 includes a shield body 1101, a shaft accommodating chamber 1102, a first bolt accommodating chamber 1103, a second bolt accommodating chamber 1104, a third bolt accommodating chamber 1105 and a fourth bolt accommodating chamber 1106 arranged in the shield body 1101, a first terminal through-hole 1107 and an insulator through-hole 1108 arranged at both ends of the shield body 1101, and a second terminal through-hole 1109 arranged in the middle of the shield body 1101.
