Description

Technical Field

[0001] The utility model relates to the technical field of transformer testers, in particular to a quick wiring structure of a transformer tester. Background Art

[0002] Transformer, also known as instrument transformer, is a general term for current transformer and voltage transformer. It can convert high voltage into low voltage and high current into low current. It is used for measurement or protection system. Its main function is to convert high voltage or high current into standard low voltage (100V) or standard low current (5A or 1A, both refer to rated value) in proportion, so as to realize the standardization and miniaturization of measuring instruments, protection equipment and automatic control equipment. At the same time, transformer can also be used to isolate high voltage system to ensure the safety of people and equipment.

[0003] The authorization announcement number CN219552640U discloses a transformer calibrator. The device mainly rotates the fixed shaft through the cooperation of the ventilation mechanism, the heat conduction block, the heat dissipation fins, the fixed cylinder, the fixed shaft, the support rod, the clamp block and the movable sleeve. The fixed shaft drives the clamp block to move through the support rod to adjust the angle of the support frame, and then the fixed shaft is loosened, the clamp block is reset, and the support frame is limited. The heat conduction block dissipates the heat generated by the transformer calibrator body through the surface of the heat dissipation fins, and the ventilation mechanism generates airflow to guide the heat to the outside. However, when the device is actually used, the following defects still exist:

[0004] The above patent mainly dissipates the heat of the transformer calibrator body by ventilating and dissipating the heat. However, when the transformer calibrator is plugged in, it is generally necessary to splice the plug with the transformer jack. However, the position of the jack is often exposed to the outside. After wiring, it is easy to be affected by the external environment, causing the line connection part to be corroded by collision and water, resulting in poor safety of the transformer calibrator wiring structure. In addition, it is necessary to find the socket position when wiring, and multiple sockets may be in different positions, further increasing the difficulty and inconvenience of wiring operation.

[0022] A guide sleeve 15 is installed on one side of the top of the transformer tester body 1, and an internal thread block 17 is installed on the top of the guide sleeve 15. A screw rod 16 with thread adaptation is sleeved on the inner side of the internal thread block 17, and an internal thread sleeve 14 with thread adaptation is provided on the outer side of the screw rod 16, and the internal thread sleeve 14 moves up and down inside the guide sleeve 15. A U-shaped bracket 13 is installed at the bottom of the internal thread sleeve 14, and multiple groups of traction wheels 12 are sleeved on the inner side of the U-shaped bracket 13. A protective plate 8 is installed on the top of one side of the U-shaped bracket 13, and a guide wheel 9 is sleeved on the bottom of the protective plate 8. A positioning block 11 is installed at the bottom of the U-shaped bracket 13. Four groups of card slots 10 are opened on both sides of the top of the terminal block 4, and every two groups of card slots 10 are plugged and fixed with the positioning block 11. The screw rod 16 and the internal thread sleeve 14 are both arranged on the inner side of the guide sleeve 15, and the internal thread sleeve 14 is limited and movable on the inner side of the guide sleeve 15, so as to facilitate the contact positioning of the line by adjusting the lifting and lowering of the structure.

[0023] Embodiment 1, as Figure 1-3 As shown, conical blocks are installed at the bottom of the two groups of positioning blocks 11, and the inner sides of the four groups of slots 10 are conical groove structures that are engaged and fixed with the conical blocks. The conical blocks with conical structures cooperate with the conical groove structures, so that the two groups of positioning blocks 11 can be more easily automatically calibrated and embedded in the slots 10 for fixation under the traction of the conical structure, thereby increasing the stability of the structural insertion and positioning.

After the line is connected, the positioning of the wiring seat 4 is loosened again, and the wiring seat 4 is pushed back into the protective groove 2 for hidden protection. When the wiring seat 4 is reset, the U-shaped bracket 13 and the positioning block 11 are lowered again to be re-inserted and spliced ​​with the card slot 10 to position the wiring seat 4. At the same time, the traction wheel 12 on the inner side of the U-shaped bracket 13 is contacted with the line for positioning, and the protective plate 8 is used to shield and protect the end face of the empty slot 7 to prevent foreign objects and water from penetrating into the interior of the device, thereby increasing the safety protection of the device to the line structure.
