Put, only in the case where product closes a floodgate, press test button, test loop could be turned on；The installation modulus of finished product reduces.This
Utility model use technical scheme be：
A kind of experimental rig of residual current action breaker, including contact supporter, test spring, testing button；
The contact supporter includes connected the first flank and the second flank, provided with a projection on the second flank,
Towards the end side surface formation test spring contact surface of test spring in residual current action breaker in projection；Contact supporter and
Moving contact is installed on shell；
Test spring includes a long shoot arm and a brachyplast arm；It is the convolution for playing elastic force effect between long shoot arm and brachyplast arm
Circle；Test spring is arranged in shell, and its long shoot arm tip is bent to form section anyhow to side, section and the experiment in shell anyhow
Resistance offsets；Brachyplast arm is stuck in the neck of testing button bottom；
Testing button includes the button portion on its top and the neck of bottom；Testing button, which is erect, is arranged on cover top portion, its
The neck of bottom blocks the brachyplast arm of test spring；
In gate-dividing state, testing button, brachyplast arm and the test spring in contact supporter projection of test spring are pressed
Contact surface is not contacted.
Further, testing button both sides are additionally provided with guiding rib, are engaged with the guide groove on shell.
Further, two flanks of contact supporter are provided with pin-and-hole, and contact supporter and moving contact are installed by pin
In on shell.
Further, the first flank and the second flank of contact supporter are almost parallel.
The utility model has the advantage of：In "on" position, the testing button of experimental rig is pressed, test loop can be led
It is logical, in the case of not pressing testing button, there are enough creep age distances, test loop pressure-resistant will not puncture；Using this experiment
Device, the reliability of product is improved, and security is more preferable.The installation modulus of finished product is smaller, easy for installation, saves space.

Embodiment
With reference to specific drawings and examples, the utility model is described in further detail.
The experimental rig for the residual current action breaker that the utility model is provided, as shown in Figure 1, Figure 2, Figure 3 shows, including is touched
Head supporter 1, test spring 2, testing button 3；
The contact supporter 1 includes connected the first flank 101 and the second flank 102, the first flank 101 and the second side
The wing 102 is almost parallel；Provided with projection 103 on the second flank 102, the shape of projection 103 is not limited, can be triangle or
Rectangle；Towards the end side surface formation test spring contact surface of test spring in residual current action breaker 2 in projection 103
1031；Two flanks of contact supporter 1 are provided with pin-and-hole, for rigging pilotage 7；
Two flanks of contact supporter 1, play a part of supporting moving contact 5；Contact supporter 1 and moving contact 5 are relied on
Pin 7 is installed on shell 4；By a diameter 1.5mm pin 7 and touch spring between moving contact 5 and contact supporter 1（Do not draw
Go out）Connection, is to be flexibly connected；Moving contact 5 and contact supporter 1 can be rotated around pin 7, and contact bullet is reversed when rotation
Spring, can provide the pressure that moving contact 5 is contacted with static contact 6；
Test spring 2 includes a long shoot arm 201 and a brachyplast arm 202；It is to play between long shoot arm 201 and brachyplast arm 202
The turning circle 203 of elastic force effect；Test spring 2 is arranged in shell 4, and its tip of long shoot arm 201 is bent to form anyhow to side
Section 204, this anyhow section 204 offseted with test resistance in shell 4, be connected by test resistance with L phases；Brachyplast arm 202 is stuck in
In the neck 302 of the bottom of testing button 3；
Testing button 3 includes the button portion 301 on its top and the neck 302 of bottom；Testing button 3, which is erect, is arranged on shell
4 tops, the neck 302 of its bottom blocks the brachyplast arm 202 of test spring 2；In addition, the both sides of testing button 3 are additionally provided with guiding rib,
It is engaged with the guide groove on shell 4, testing button 3 can be caused, which to press when being resetted with resilience, has guide effect；
As shown in figure 4, in gate-dividing state, even if pressing testing button 3, brachyplast arm 202 and the contact of test spring 2 are supported
Test spring contact surface 1031 in the projection 103 of part 1 is not contacted still, leaves enough creep age distances；
