Description

[Detailed Description of the Invention] The present invention relates to a device for testing the insulation resistance and dielectric strength of a cord reel.

Conventionally, to test the insulation resistance and dielectric strength voltage of cord reels, each was tested using a dielectric strength meter, but this required manual labor and the output voltage was 500V.
The voltage is as high as ~1600V, which poses a danger, and it also has many inconveniences, such as very poor work efficiency and unsuitability for line systems.

In view of the above-mentioned conventional inconveniences, the present invention has been developed to develop a cord reel insulation resistance and dielectric strength voltage that is safe and efficient and can automatically test insulation resistance and dielectric strength voltage using mechanical equipment on a series of lines. The purpose is to provide inspection equipment.

9 is the front pallet guide. Reference numerals 30 and 31 are cord wire insertion ports installed in the cord wire insertion jig 27. The cord reel conveyance pallet 22 is conveyed in advance in the state shown in the figure, and the pin 33 is inserted into the fixed cylinder 32 from below to maintain it in the state shown in the figure.

Next, the operating state of the device of the present invention will be explained with reference to FIG. When the cord reel conveying pallet 22 that has been conveyed is fixed in the state shown in the figure, the insulation resistance test jig mounting plate 1 is moved by the air cylinders 7 and 7'.
1 is lowered and the cord line shorting switch 20 is activated by the shorting switch OFF spring 19.
When turned OFF, the insulation resistance test connector 15
are in contact with the upper cover 2 of the cord reel A, and the contacts 17a on both arms of the plug contact hand 17 for insulation resistance testing are in contact with the upper cover 2 of the cord reel A.
17b respectively contact both contact terminals of the plug 4. Next, under the control system of a control box (not shown), a voltage of 500 V is first applied between the contacts 17a and 17b on both arms of the plug contact hand 17 for insulation resistance testing, and a current flows. This current is used to test the insulation resistance between the cords inside the cord reel A through both contact terminals of the plug 4. Next, a voltage of 500 V is applied between one contact 17a of the plug contact hand 17 for insulation resistance testing and the contact 15 for insulation resistance testing, and a current flows.
Using this current, the insulation resistance between one of the cords leading from one contact terminal of the plug 4 and the top cover 3 is tested. Next, a voltage of 500 V is applied between the other contact 17b of the insulation resistance testing plug contact hand 17 and the insulation resistance testing terminal 15, and a current flows to connect the other cord to the other contact terminal of the plug 4. Inspect the insulation resistance between the upper cover 3 and the upper cover 3. If a defect is detected in one of the above three types of insulation resistance, the marking cylinder 13 for insulation resistance defect is activated, and the marking part 13a is lowered to place a mark of insulation resistance defect on the surface of the upper cover 2 of the cord reel A. push. The cord reel A marked with the defective mark is selected at the end of a series of machines. Furthermore, as is clear from the figure, the test for the dielectric strength of the cord reel is carried out in the same manner as the above-mentioned test for the insulation resistance, and the dielectric strength is tested at a voltage of 1600V. The structure and operation are almost the same as the insulation resistance testing device, so the explanation will be omitted.

Since the device of the present invention has the above-mentioned configuration and function, it can be installed on the same line that assembles cord reels, so it can automatically and safely measure the insulation resistance and dielectric strength voltage of cord reels without requiring any human intervention. The present invention provides a new and efficient cord reel insulation resistance and dielectric strength testing device that can test the insulation resistance and dielectric strength of cord reels.
