On, partition includes the interconnecting piece of two blocks of side plates of two blocks of side plates and connection, and interconnecting piece opposite side is open side.
It deletes
Further, the open side of partition is equipped with a pair of of buckle, and partition is by being connected on contact.
Further, the inside of two blocks of side plates of the open side of partition is equipped with chamfering.
Further, the interconnecting piece of partition includes the same side at least two and positioned at side plate, and the medial surface of interconnecting piece can
It is fitted on contact.
Further, contact side corresponding with the open side of partition be equipped at least one at recess, the two of recess and partition
A side plate forms groove, and groove can limit the spring between moving contact and contact support.
Further, clamping structure is equipped between two neighboring partition.
Further, clamping structure includes the card slot and snap-gauge for being respectively arranged on partition two sides, one in two neighboring partition
The snap-gauge of partition, which can be inserted into the card slot of another partition, to be clamped.
Further, the lower partition is equipped with perforation corresponding with the hole on contact.
It further, further include connecting shaft, the perforation that connecting shaft passes through the hole on contact and the partition being mounted on contact
Multiple contacts are strung.
The utility model is beneficial in that, when installation, by partition installation corresponding with the contact on contact, that is, forms mould
Blockization combination, convenient for assembly.Contact quantity need to only increase partition quantity when changing, without redesigning Contact Cover.Partition
Contact can be separated, the contact area of contact is influenced after attracting each other when preventing high current from passing through, and has the function of Contact Cover concurrently, is disappeared
In addition to the gap generated when contact movement with Contact Cover, it ensure that the air-tightness of contact system, be conducive to pneumatic arc blow-out.

Specific embodiment
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments:
As shown in Figures 1 to 6, a kind of novel breaker moving contact, moving contact are equipped with multiple contacts 1, and multiple contacts 1 are
Partition 2 is installed, partition 2 is mountable on one or more contacts 1.Partition 2 includes two blocks of side plates of two blocks of side plates 21 and connection
21 interconnecting piece 24,24 opposite side of interconnecting piece are open side.The open side of partition 2 is equipped with a pair of of buckle 23, and partition 2 passes through buckle
23 are connected on contact 1.The inside of two blocks of side plates 21 of the open side of partition 2 is equipped with chamfering 22.The interconnecting piece 24 of partition 2 includes
The same side at least two and positioned at side plate 21, the medial surface of interconnecting piece 24 can be fitted on contact 1.Contact 1 is opened with partition 2
The corresponding side in mouth side is equipped with recess 11 at least one, two side plates 21 composition groove of recess 11 and partition 2, and groove can limit
