Folder open away from less it is difficult to clamping blossom type contact, easily cause both loose contacts, test inaccurate, and wire clamp energising send out
The spring of thermal capacitance easy damaged shroud ring contact, causes spring Aging Damage, elastic force to decline.And the model of blossom type contact is not yet
With same test clamp is difficult to general to all of quincunx contact.
Utility model content
The purpose of this utility model is exactly to solve the above problems, there is provided a kind of built-in circuit breaker electric test line
Folder, wire clamp contact is stuck on blossom type contact inwall and is tested it is possible to according to chopper blossom type contact internal diameter not
With the wire clamp contact changing corresponding size, to ensure both good contacts, and contact of breaker will not be injured.
To achieve these goals, this utility model adopts the following technical scheme that：
A kind of built-in circuit breaker electric test wire clamp, cuts arm including two by what pin connected, described cuts the one of arm
End is flexibly connected wire clamp contact, and the other end connects retractable handle, cuts for two and is additionally provided with tension spring between arm；Arm is cut described in each
All it is connected with wire；Described wire clamp contact camber, and outer surface becomes the corrugated coincideing with blossom type contact.
Described wire clamp contact passes through being connected of threaded screw bore with cutting arm.
The termination of described retractable handle connects deposits the backup cartridge replacing wire clamp contact.
Described backup cartridge is flexibly connected with retractable handle, can take off backup cartridge when using, select suitable types
Backup cartridge is linked together after being finished by wire clamp contact with retractable handle, using depositing, not easy to lose.
Described retractable handle adopts epoxide resin material.
The beneficial effects of the utility model are：
This utility model acts on blossom type contact inwall using scissor mechanism, and according to different model chopper blossom type
Contact, the wire clamp contact of design corresponding size, changed as needed in test.
Wire clamp contact is screwed on scissors clip mechanism, is conveniently replaceable and safeguards, wire clamp contact adopts arc
Wave structure, to increase the effect of the contact with blossom type contact.
Tension spring elastic force needs carry out excellent according to factors such as scissors clip mechanism size, the sizes of blossom type contact
Change and select, to ensure that it can be with blossom type contact good contact, without regard to because of overtension damage contact.
Wire clamp handle adopts insulating stretchable type structure, using the good epoxide resin material of insulating properties and mechanical strength,
With guarantee test personnel safety and reliability in operation.
Economic benefit：This device contacts reliability with contact of breaker, will not injure out contact shroud ring spring, decrease open circuit
Device maintenance cost.
Grid benefit：Built-in electric test wire clamp is directly clamped among to be tested on chopper blossom type contact inwall, tool
There is good safety, and test accuracy is higher, it is to avoid factor data mistake causes grid loss.
Productivity effect：Using this apparatus structure is simple, practical function, can effectively reduce the operating time, improve work effect
Rate.
