Description
Technical field
The utility model relates to a kind of installation tool more particularly to a kind of installation tools of contacts for vacuum-break switches.
Background technique
With the extensive use of vacuum circuit breaker, in process of production, contact is difficult to install for business unit.Removing contact
When holding spring tightly, spring and contact are held in damage tightly, damage contact coating, and plucking contact causes point discharge.So needing one kind
Contact can be installed to the specific purpose tool on contact arm without removing holding spring, and contact will not be damaged and hold spring tightly.
Utility model content
The utility model mainly solves the deficiencies in the prior art, provide it is a kind of compact-sized, easily to operate
Contacts for vacuum-break switches installation tool solves the problems, such as a kind of vacuum circuit breaker touching of inefficiency damage contact when contact installation
The installation tool of head.
Above technical problems of the utility model are mainly solved by the following technical scheme:
A kind of installation tool of contacts for vacuum-break switches, including support are equipped with assembly void column in the support, described
The contact arm that half built-in is equipped in void column is assembled, the upper end of the contact arm is equipped with Embedded guide rod, the guide rod
Low side be cased with contact, the top of the contact is equipped with the pressing plate with guide rod empty set, and the pressing plate is resilient with contact
Crimping.
Preferably, the tapered distribution in cross section of the guide rod lower end, the upper end of the guide rod is assembly
Stepped end；The contact arm is in cylinder hollow shape, and the outer wall of the contact arm upper end is assembly ring recess；The middle-end of the pressing plate
To be discoid, the two side ends of the pressing plate are respectively equipped with the outwardly extending arm of force.
The tool construction is simple, easy to use to be mainly made of guide rod, support, pressing plate.It is easy to operate, contact arm is packed into
Support, the guide head of guide rod are inserted into contact arm hole, and contact is put into from guide rod top, then pressing plate is put into guide rod, firmly to
Next pressure pressing plate, contact just import in contact arm, finally pull out the installation that guide rod just completes contact.
Support prevents from swinging because of fixed contact arm, and pressing plate both ends are equipped with Lengthened moment arm, and contact is easily imported contact arm.
In use, pressing plate is placed on smooth workbench, contact arm is packed into the mesoporous of pressing plate, and contact arm is not when installing contact
It can swing.Again by the centre bore of the guide head insertion contact arm of guide rod, guarantee coaxial.Contact is filled from guide rod top again
Enter, because guide rod lower part is designed for pyramid type, conveniently struts contact.Finally pressing plate is inserted in from guide rod top, pressing plate is put down
Face and contact completely contact, and both hands hold the hand handle at pressing plate both ends, are firmly pressed downward, and contact bears pressure, along guide rod
Circular conical surface moves down, and imports in contact arm, and the anti-skidding place for holding guide rod top pulls out guide rod upwards, completes the installation of contact.
The utility model provides a kind of installation tool of contacts for vacuum-break switches, improves service performance, raising efficiency.
