The movable ground portion 63 is formed on the fixing projection 62a provided at the upper center of the support plate 69 provided below the space portion 68 formed in the middle of the movable bar 62. The through-hole 65 is coupled to and installed, a spring 67 having a lower portion seated on an upper portion of the through-hole 65 in the center of the movable ground portion 63, and the spring 67 is the movable bar 62. The lower portion of the spring (67) is the upper portion of the through hole 65 of the movable ground (63) when repeatedly compressed and expanded based on the body (61) together with the movable bar (62) during the lifting movement of the The lower portion of the spring 67 is separated from the locking jaw 66 to the left and right when the movable ground portion 63 which is lifted up and down with the movable bar 62 is seated on the locking jaw 66 formed on the surface. To prevent the spring bar 67 from being moved up and down by moving the movable bar 62 and the movable ground portion 63 based on the body 61. The movable ground portion 63 installed on the movable bar 62 facilitates the detachment from the fixed ground portion 64 by assisting the rise of the movable bar 62 due to the repeated expansion and compression. This is to prevent the damage of the various components connected to the electromagnetic magnetic contactor 100 in the high-speed train by breaking the 63 from the fixed grounding part 64 to cut off the voltage of the electromagnetic magnetic contactor 100.
