Round pin shape tension disk

The utility model relates to an electromechanical class or electrical apparatus class product have the wire clamping structure of the circuit use of plug, specifically are round pin shape tension disk. A round pin shape tension disk, comprises two dops that are fixed in on the cassette, one of them dop is the type shape structure of another dop of convex part orientation, open on another dop relative with this type shape structure have with the same recess of type shape structure appearance, the type shape structure and the groove phase cooperation of one of them dop forms bending type's draw -in groove to two dops are made by elastic material. A round pin shape tension disk convenient to use, dismantles also conveniently, has guaranteed circuit and round pin shape tension disk's card and put firmly that practicality, security and steadiness all improve greatly, are particularly useful for having the electromechanics or the electrical apparatus class product of longer more circuit.
