Detailed Description
Referring to fig. 1-3, a moving and static contact combined structure comprises a ceramic cover 1, wherein a step 2 is arranged in the center of the ceramic cover, and is characterized in that a bearing plate 3 is arranged below the ceramic cover, and an annular sleeve is arranged on the outer peripheral edge of the bearing plate; a moving contact device is arranged in the center of the bearing plate, and a static contact device matched with the moving contact device for use is arranged on the ceramic cover; the moving contact device comprises a moving contact 4 which is arranged on the bearing plate and can be lifted, and a driving device which is positioned in the bearing plate and drives the moving contact to lift; the moving contact is of a disc structure. In implementation, a lifting rod of the driving device extends to a cavity below the ceramic cover towards the upper part of the bearing plate, and a movable contact is arranged at the top end of the lifting rod and is also positioned in the cavity below the ceramic cover so as to be convenient for contacting with a fixed contact; the driving device drives the moving contact to move upwards to be in contact with the static contact device, the moving contact can rotate freely in the contact process, the product can rotate in the action process, the round surface of the moving contact can be uniformly lost, and the service life of the product is prolonged.
The static contact device comprises a first mounting hole 5 and a second mounting hole 6 which are arranged on the top surface of the step, and static contacts 7 are arranged in the first mounting hole and the second mounting hole. In implementation, the bottom end of the static contact extends into the cavity below the ceramic cover and is in contact with the moving contact, so that an external element can be conveniently plugged; furthermore, the first mounting hole and the second mounting hole are arranged up and down, so that the static contacts in the first mounting hole and the second mounting hole are not positioned on the same horizontal line, the direction of a connecting line between the two static contacts is not vertical to the direction of a magnetic field formed by the upper magnetic steel and the lower magnetic steel, and the main loop can be used in a non-polar mode.
The driving device comprises a lifting rod 8, one end of the lifting rod extends into the containing cavity to be connected with the moving contact, and the other end of the lifting rod penetrates through the static iron core and the moving iron core in sequence. In the implementation, the lifting rod is driven to move by the movement of the movable iron core; the specific structure of the driving device can be referred to patent document 2017216481782, entitled auxiliary device for synchronous feedback, which is specifically located in paragraphs 0017-0018 of the specification and is not described too much here.
The moving contact rotates along with the lifting rod.
Both sides of the step are arc-shaped side edges 9; clamping parts are arranged on two sides of the step; the clamping component is an outer magnetic circuit clamp 10, the middle part of the outer magnetic circuit clamp is outwards supplied to form an arc section 11 matched with arc side structures on two sides of the step, two sides of the arc section are oppositely provided with L-shaped corner sections 12, and exposed ends of the corner sections are outwards bent and extend to form transverse sections 13; in the implementation, the two sides of the quadrilateral boss are arc-shaped side edges which are more attached to the peripheral edge of the ceramic cover; the arc-shaped structure protrudes outwards, so that when the arc-shaped structure is matched with an external magnetic circuit clamp for use, the arc-shaped structure can be clamped more firmly; the upper magnetic steel and the lower magnetic steel are clamped on the upper side edge and the lower side edge of the step through the corresponding transverse sections of the outer magnetic circuit clamps.
