Abstract
Description
Technical Field
[0001] This utility model belongs to the field of terminal block testing technology, and in particular relates to a high temperature resistance testing device for terminal blocks. Background Technology
[0002] Terminal blocks are particularly susceptible to accelerated aging and damage due to high temperatures. Different insulation materials have varying heat resistance properties, resulting in different high-temperature tolerances for terminal blocks made with different insulation materials. Therefore, terminal blocks need to be tested for high-temperature resistance in a heating chamber after manufacturing.
[0003] When terminal blocks are placed in a heated testing chamber, they are mostly in a static state. Since the distance between the terminal blocks and the hot air vent varies in different positions, a high-temperature resistance testing device for terminal blocks is needed to avoid uneven heating of terminal blocks in different positions. This device can rotate the terminal blocks back and forth to continuously change their position, thereby ensuring that the terminal blocks are heated evenly and improving the accuracy of high-temperature resistance testing of terminal blocks in the same batch. Utility Model Content

[0012] 1. The beneficial effects of this utility model are: This utility model inserts the terminal block into the inner cavity of the hole block, and then drives the rack to move through the electric telescopic rod, so that the rack drives the rotating rod to rotate back and forth through the tooth plate. Then, the rotating rod drives the terminal block on its surface to be heated evenly. This achieves the purpose of improving the accuracy of high temperature resistance testing of the same batch of terminal blocks by continuously changing the position of the terminal block through reciprocating rotation, thereby ensuring that the terminal block is heated evenly.

[0025] In the following description, embodiments of the high-temperature resistance testing device for the terminal blocks of this invention will be described with reference to the accompanying drawings.
[0026] Example 1:
[0027] Figure 1-4 This invention illustrates a high-temperature resistance testing device for terminal blocks according to an embodiment of the present invention. It includes a heating chamber 1. A control box 2 is bolted to the surface of the heating chamber 1. A rotating rod 3 is rotatably connected to the inner wall of the heating chamber 1. The top end of the rotating rod 3 extends through to the top of the heating chamber 1 and is fixedly connected to a toothed plate 4. A horizontal plate 5 is welded to the top of the heating chamber 1. An electric telescopic rod 6 is fixedly installed on the top of the horizontal plate 5. A rack 7 is fixedly connected to the output end of the electric telescopic rod 6 via a flange. The toothed plate 4 meshes with the rack 7. A limit sleeve 8 is slidably connected to the surface of the rack 7. The limit sleeve 8 is bolted to the horizontal plate 5. The movement of the rack 7 is controlled by the limit sleeve 8. Limiting is implemented to prevent the rack 7 from wobbling during reciprocating movement. The top of the horizontal plate 5 is fixedly installed with a housing 9 by bolts. The housing 9 covers the outer sides of the rack 7 and the toothed plate 4, preventing the rack 7 and the toothed plate 4 from biting into foreign objects during operation. The front side of the heating chamber 1 is rotatably connected to the door panel 11 by a hinge. The surface of the rotating rod 3 is fixedly connected to the hole block 13. The inner wall of the hole block 13 is covered with a protective gasket 14, which is a high-temperature resistant gasket. The protective gasket 14 protects the inner wall of the hole block 13, preventing scratches from occurring when the wiring terminals come into direct contact with the inner wall of the hole block 13.
[0028] Example 2:
[0029] Figure 1-4This invention illustrates a high-temperature resistance testing device for terminal blocks according to an embodiment of the present invention. The device includes a heating chamber 1. A control box 2 is bolted to the surface of the heating chamber 1. A rotating rod 3 is rotatably connected to the inner wall of the heating chamber 1. The top end of the rotating rod 3 extends through to the top of the heating chamber 1 and is fixedly connected to a toothed plate 4. A horizontal plate 5 is welded to the top of the heating chamber 1. An electric telescopic rod 6 is fixedly installed on the top of the horizontal plate 5. A rack 7 is fixedly connected to the output end of the electric telescopic rod 6 via a flange. A glass block 10 is embedded and fixedly installed on the right side of the heating chamber 1. The glass block 10... This design facilitates observation of the inner cavity of the heating chamber 1, preventing situations where the wiring terminals inside the heating chamber 1 are difficult to inspect during the heating process. A door panel 11 is rotatably connected to the front of the heating chamber 1 via a hinge. A hole block 13 is fixedly connected to the surface of the rotating rod 3. A bearing 15 is fixedly installed on the top of the heating chamber 1 via bolts. The inner wall of the bearing 15 is in contact with the surface of the rotating rod 3. The bearing 15 limits the rotation of the rotating rod 3, and the friction between the bearing 15 and the rotating rod 3 is small, effectively preventing the rotating rod 3 from shaking during rotation.
[0030] Working principle: When using this utility model, the user inserts the terminal block into the inner cavity of the hole block 13, then closes the door panel 11 and opens the heating chamber 1 through the control box 2 to heat and test the terminal block. At the same time, the electric telescopic rod 6 is activated to drive the rack 7 to move, so that the rack 7 drives the rotating rod 3 to rotate back and forth through the toothed plate 4. Then, the rotating rod 3 drives the terminal block on its surface to be heated evenly through the hole block 13. By rotating the terminal block back and forth, the position of the terminal block can be continuously changed, thereby making the terminal block heat evenly heated, thus improving the accuracy of high temperature resistance testing of the same batch of terminal blocks.
[0031] In summary, this high-temperature resistance testing device for terminal blocks achieves its purpose by inserting the terminal block into the inner cavity of the hole block 13, and then moving the rack 7 via the electric telescopic rod 6. The rack 7 drives the rotating rod 3 to reciprocate through the toothed plate 4, and the rotating rod 3 drives the terminal block on its surface to be uniformly heated through the hole block 13. This reciprocating rotation of the terminal block allows its position to be continuously changed, thereby ensuring uniform heating of the terminal block and improving the accuracy of high-temperature resistance testing for the same batch of terminal blocks.
