On backing plate 17 under backing plate 16 and b copper bars 20.Small contact frame member 15 is connected and around it with small contact frame member stent 35 by hinge L
Rotation.
As shown in Figure 4,5, big contact frame member 8 is welded by outline border 23,25, and there are two the rectangular of projecting arm 31 for a band
The outer framework of shape big contact frame, in 8 outer framework of big contact frame member, be made of by every group 4 long-armed contact blades 22 one group three
Group leader's arm contact blade group and two separation blocks 26 for separating three groups long arm contact blade component；In 8 outer framework of big contact frame member
Spring there are two being loaded between the same side of each long-armed contact blade 22 in interior every group leader's arm contact blade group and outer framework
28；In 8 outer framework of big contact frame member, also upper padding plate 24 is placed in the three groups long arm contact blade group with spring 28 and two generals
On the separation block 26 that three groups long arm contact blade component separates between outline border 23, separate under block 26 and big at two
It is also each between the outer framework of contact frame member 8 that there are one backing plates 27；It is solid in one end of the long-armed contact blade group of 8 each group of big contact frame member
It is scheduled on rocker bar bearing F, is connect with big contact frame member stent 3；Each small contact frame member X, Y, Z in three small contact frame member 15
Respectively include the rectangle outer framework 29 there are one projecting arm 32 there are one band, such as in the outer framework 29 of small contact frame member X, there is one
The long-armed contact blade group that group is made of 4 long-armed contact blades 30；It is every in contact blade group in small contact frame member outer framework 29
Spring 33 there are two all being loaded between the same side of a contact blade 30 and small contact frame member outer framework 29；The length of small contact frame member 15
One end of arm contact blade group is each attached on the hinge L of respective small contact frame member stent 35, is connected with small contact frame member stent 35
It connects；The other end of 3 long-armed contact blade groups of big contact frame member 8,3 long-armed contact blade groups with 3 small contact frame member X, Y, Z
The distance between another free end be equal to the distance being detected between 12 three-phase inlet-outlet line connection jaws of breaker of plastic casing.It can be just
It is good that their long-armed contact blade 22,30 is connected with the three-phase entrance end of detected breaker of plastic casing 12.
This fixture is divided into the two independent parts in left and right, and the operation principle on both sides is identical, only in view of TM30-400
Testing requirements so that the form of size contact frame member and quantity are different.
Operation principle is：When the cylinder rod of big cylinder 11 is retracted, hinge C is moved axially with the cylinder rod of big cylinder 11,
Big set square 2 will be rotated counterclockwise around the fixed hinge bearing B on big triangle board mount 7, thus drive big set square
Hinge D on stent 7 is rotated around fixed hinge bearing B, while also connecting rod 9 is driven to make nearly vertical upward movement, big in this way
For contact frame member 8 under the action of connecting rod 9 pushes up power, the fixed hinge bearing F around big contact frame member stent 3 opens certain angle,
When the cylinder rod of big cylinder 11 is retracted, while the cylinder rod of small cylinder 13 is controlled to retract, such small contact frame member 15 also can be simultaneously
It opens；At this moment, detected TM30-400 workpiece 12 are put into, large and small cylinder is controlled to release simultaneously, large and small contact frame member 8,15
It can fall simultaneously on the port of inlet-outlet line up and down for being pressed on TM30-400 workpiece 12, carry out test of correlation.I.e. or with a fixture left side
For rim portion, when the cylinder rod of big cylinder 11 stretches out, big set square 2 is pushed to be rotated clockwise around fixed hinge bearing B, greatly
Set square 2 drives connecting rod 9 almost vertically to move downwardly to Fig. 1,2 positions by hinge D, makes the length of big contact frame member 8
Another free end of arm contact blade group is pressed on the three-phase outlet port of detected TM30-400 workpiece 12.And 3 small contacts
Another free end of the long-armed contact blade group of frame member 15 is pressed on the three-phase inlet wire port of detected TM30-400 workpiece 12
As shown in Fig. 1,6,7,8 times two big cylinders 11 of connection of big contact frame member provide power, 3 small contact frame member for it
Power respectively is provided for them there are one small cylinder 13 under X, Y, Z this 3 small contact frame member in 15, passes through solenoid signal control
It makes the release and retraction of each cylinder, and then controls compression of the large and small contact frame member 8,15 on workpiece and lift.This fixture work
When making, power on circuitry is first such as accessed into the end of copper bar 20 and 21, then control size cylinder 11,13 acts to control respectively
Large and small contact frame member 8,15 acts, and big contact frame member 8 is kept to compress and is detected TM30-400 workpiece 12, allows small contact frame member X, Z
Pressure, Y are lifted, it is possible to realize the alternate energization detections of the ac for being detected TM30-400 workpiece 12；Small contact frame member Y, Z is allowed to press
Under, X is lifted, it is possible to realize the alternate energization detections of the bc for being detected breaker 12；Detected breaker 12 is moved to side
A phase spacing is moved, as shown in fig. 7, big contact frame member 8 is kept to depress, small contact frame member Y, Z pressure, X is lifted, it is possible to real
Now it is detected the alternate energization detections of the ab of breaker.
