Summary of the invention
But there is following problems in the structure of existing controller for motor.
Because 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, therefore current capacity deficiency when making probe contact screw or conductive plate, 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 to 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 by 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, owing to,, can easily test so can make probe contact conductive plate according to the resin portion of delivery test with the shape local excision conduction board of probe.
Owing to can easily test, thus can carry out simply robot from dynamic test, can improve operation.
According to scheme 2 described inventions,,, can improve the reliability of test so eliminated the short circuit that is caused because of the current capacity deficiency owing on conductive plate, be formed for increasing contact-making surface with the contact area of probe.
According to scheme 1 and scheme 2 described inventions, 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 3 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 4 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.Rise by the temperature that suppresses terminal board, can make the terminal board miniaturization.By making the terminal board miniaturization, can make the controller for motor miniaturization.
