Summary of the invention
But there is following problems in the structure of existing controller for motor.
Owing to when carrying out the delivery test of controller for motor, covered by resin around the conductive plate of major loop terminal platform, so the conductive part of contact probe is less, current capacity is not enough when making probe contact screw or conductive plate, therefore, has caused short circuit.Therefore, unclamp screw lead is installed on major loop terminal platform, after this tighten screw and carry out delivery test.In addition, unclamping screw after the delivery test takes lead and tightens screw with the regulation torque.So, because being provided with of delivery test needs the time, so there is limitation in the shortening of activity duration.Therefore, the reduction activity duration realizes that it is limited that the cost of controller for motor reduces.In addition, in the low major loop terminal platform of current value,, reduced the thickness of slab of conductive plate in order to make the controller for motor miniaturization.Because the thickness of slab of conductive plate is thinner, so caused the undercapacity of the lead terminal of conductive plate.Therefore, need cover around the conductive plate with resin.If with the lead terminal of resin covering conductive plate, then heat is enclosed in the temperature rising of inner major loop terminal platform.If the temperature of major loop terminal platform rises, then the reliability step-down of major loop terminal platform.In order to keep the reliability of major loop terminal platform, need to suppress temperature and rise, rise in order to suppress temperature, must increase the thickness of slab of conductive plate.If increase the thickness of slab of conductive plate, then need increase major loop terminal platform, therefore, the miniaturization of controller for motor is limited.
The present invention carries out in view of the above problems; Purpose is to provide a kind of controller for motor, can cut down the activity duration of delivery test, reduces cost; Improve the reliability of test, and then carry out the miniaturization of device through the miniaturization of carrying out major loop terminal platform.
In order to address the above problem, the present invention is following formation.
According to the present invention, has following effect.
According to scheme 1 described invention,,, can easily make an experiment so can make probe contact conductive plate because a plurality of conductive plates possess the conductive plate probe contact-making surface that exposes to the outside in the face side of said major loop terminal platform.
Owing to can easily make an experiment, thus can carry out simply robot from dynamic test, can improve operation property.
In addition, owing on conductive plate, be formed for increasing the contact-making surface with the contact area of probe,, can improve the reliability of test so eliminated because of the not enough short circuit that is caused of current capacity.
In addition, though from frontal when conductive plate applies power, owing to have the contact-making surface of probe on the conductive plate, so this contact-making surface also can holding capacity, conductive plate can not tilt yet.Because conductive plate can not tilt,, can improve assembleability so can not install badly.
According to scheme 2 described inventions,, widely form the lead terminal width in order to increase the lead terminal intensity of conductive plate.Owing to widely form the lead terminal width, so even without this part of resin reinforcement, lead terminal can not tilt yet, conductive plate can not tilt.Because conductive plate can not tilt,, can improve assembleability so can not install badly.
According to scheme 3 described inventions, owing to widely form the lead terminal width, the resin portion of this part of local excision, so conductive plate is stroked in wind, the temperature that can suppress terminal board rises.Temperature through suppressing terminal board rises, and can make the terminal board miniaturization.Through making the terminal board miniaturization, can make the controller for motor miniaturization.Description of drawings
