Abstract
The utility model relates to a power switching-off spacing device. The power switching-off spacing device mainly settles the technical problems of troublesome mounting, complicated structure and inferior contacting of a contact. A housing of the spacing device is composed of an upper cover and a base. The upper cover is provided with a first mounting tank and a second mounting tank which are connected through a chute. A first pushing head, a first contact base, a first moving contact and a first static contact are arranged in the first mounting tank. A second pushing head, a second contact base, a second moving contact and a second static contact are arranged in the second mounting tank. A push/pull rod penetrates through the chute and one end of the push/pull rod is connected with the first pushing head. The other end of the push/pull rod is connected with the second pushing head. When the push/pull rod is pushed or pulled, separation between the first moving contact and the first static contact or separation between the second moving contact and the second static contact is caused. Because the power switching-off spacing device is obtained through splicing the upper cover and the base, a switching-off mechanism can be mounted in the upper cover just through detaching the base in mounting. The power switching-off spacing device provided by the utility model has advantages of: convenient operation, simple structure and good contacting of the contact.
