Abstract
The utility model relates to a pneumatic clamp for a moulded case circuit breaker. The pneumatic clamp comprises an advancing cylinder, a compressing cylinder, an advancing valve, a compressing valve, a moving contact, a fixed contact, upper and lower positioning blocks, a moveable plate and an installation plate. The pneumatic clamp is characterized in that the advancing cylinder and the compressing cylinder are respectively and fixedly installed on the positive side and the reverse side of the installation plate, the upper positioning block is installed on a piston rod of the advancing cylinder, the lower positioning block is fixed on the installation plate, and the moveable plate is fixed on a piston rod of the compressing cylinder. The pneumatic clamp achieves tight contact, simple structure and convenient use, and realizes the backward extrusion of the moving contact and the fixed contact in a sealed wiring chamber of a tested circuit breaker, thus causing the contact to be tight and benefiting tests.
Description
Technical field
The utility model relates to a kind of breaker of plastic casing air-actuated jaw, is particularly suitable for having the breaker of plastic casing checking table use of closed wire connection cavity.
Background technology
Isolating switch is the widest protection electrical equipment of a kind of use, and national economy and people's lives are played great function.In order to guarantee the product quality of isolating switch, must carry out verification to the capability and performance of isolating switch with checking table.Grip device is one of critical piece of isolating switch checking table, be directly connected to the serviceable life of detection quality, verification speed and the checking table of isolating switch, develop a kind of working stability, breaker of plastic casing air-actuated jaw easy to use, simple in structure, significant.
The breaker of plastic casing of closed wire connection cavity is because wiring is firm, adopted by increasing novel breaker in recent years, common breaker of plastic casing air-actuated jaw is not suitable for this class isolating switch and clamps on testing table, and the breaker of plastic casing air-actuated jaw that the utility model provides is developed with regard to being based on this problem.
Summary of the invention
The purpose of this utility model is to provide a kind of contact tight, simple in structure, easy to use, is applicable to the breaker of plastic casing test fixture with closed wire connection cavity.
In order to realize the foregoing invention purpose, the utility model adopts following technical scheme:
A kind of breaker of plastic casing air-actuated jaw, comprise carry cylinder, clamping cylinder, carry air valve, compress air valve, moving contact, static contact, locating piece, portable plate, installing plate up and down, carry cylinder, clamping cylinder are separately fixed on the pros and cons of installing plate, last locating piece is installed on the piston rod of carry cylinder, following locating piece is fixed on the installing plate, and portable plate is fixed on the piston rod of clamping cylinder.
On the locating piece, locating piece linked to each other with portable plate about moving contact passed about static contact was installed in respectively.
Compress the appropriate position that air valve is fixed on the installing plate reverse side, after anchor clamps drive the downward carry of dynamic/static contact of locating piece to the clamped position action, just in time can back down and compress air valve.
The carry air valve is fixed on the appropriate location, when anchor clamps portable plate after the release position action puts in place can back down the carry air valve.
The contact of the utility model kind is tight, simple in structure, easy to use, and this anchor clamps can make dynamic/static contact oppositely extruding in the closed wire connection cavity of tested isolating switch of anchor clamps, thereby contact closely is beneficial to test.

Embodiment
Below in conjunction with Figure of description, the utility model is described further.
Embodiment: present embodiment provides a kind of breaker of plastic casing air-actuated jaw with closed wire connection cavity, these anchor clamps by carry cylinder 2, clamping cylinder 8, carry air valve 10, compress air valve 9, moving contact 5, static contact 4, go up locating piece 3, locating piece 6, action plate 7, installing plate 1 are formed down.6 static contacts 4 are separately fixed on the locating piece on 3,6 (each 3), and following locating piece is fixed on the lower end of installing plate 1, and last locating piece is connected on the piston rod of carry cylinder 2, and carry cylinder 2 is fixed on the upper end of installing plate 1.Its connecting rod of locating piece linked to each other with portable plate 7 about 67 font moving contacts passed respectively, and portable plate is contained on the piston rod of clamping cylinder 8, and clamping cylinder 8 is fixed in the bottom surface of installing plate 1.During test, press the release button of testing table, the cylinder that unclamps of clamping cylinder 8 is brought about the desired sensation, clamping piston drive portable plate moves right and backs down carry gate 10, the cylinder that unclamps of carry cylinder 2 is brought about the desired sensation, piston moves upward and opens anchor clamps, can put into tested isolating switch this moment, after tested isolating switch puts in place, the button that compresses of pressing testing table is again brought about the desired sensation the hold-down cylinder of carry cylinder 2, piston rod moves downward and drives the closed wire connection cavity that the dynamic/static contact of going up locating piece enters tested isolating switch, locating piece drives moving contact and connecting rod and moves downward and back down and compress air valve 10 on this moment, the hold-down cylinder of clamping cylinder 8 is brought about the desired sensation, and driving up and down by portable plate 7,6 moving contacts make the external compression of anchor clamps moving contact to the breaker connection chamber to left movement; Simultaneously, 6 static contacts are motionless, are against the bottom of wire connection cavity, and it is oppositely stressed to make that like this dynamic/static contact forms in the inwall of the closed wire connection cavity of tested isolating switch, thereby dynamic/static contact is contacted closely, in closed wire connection cavity to carry out the energizing test of isolating switch.After test is finished, press the release button of testing table, the cylinder that unclamps of clamping cylinder 8 is brought about the desired sensation, clamping piston drive portable plate 7 moves right and backs down carry gate 11, and the cylinder that unclamps of carry cylinder 2 is brought about the desired sensation, and piston moves upward and opens anchor clamps, at this moment, can take out test product easily, next only test changes the outfit.
