Description

Technical Field

[0001] The present invention relates to the technical field of electronic transformer technology, and in particular to an electronic transformer protection device and method. Background Art

[0002] An electronic transformer usually refers to a transformer used in electronic devices. It is a device used to change AC voltage. The basic principle of the transformer is to use the electromagnetic induction phenomenon. The changing current in one coil (primary coil) will generate an induced electromotive force in another coil (secondary coil) close to it. According to Faraday's law of electromagnetic induction, when current passes through the primary coil, a corresponding voltage will be generated in the secondary coil. In modern electronic products, especially portable devices, a technology called "switch mode power supply" is often used. This technology uses high-frequency switches to adjust the voltage. Compared with traditional linear transformers, they are more efficient and smaller in size; The electronic transformer is small in size and is generally fixed in place by bolts or placed randomly for use. When the wires are accidentally touched by passing staff, the connection between the wires and the socket of the electronic transformer is prone to loosening, affecting the actual use effect and service life of the electronic transformer.

An electronic transformer protection device according to claim 8, characterized in that: A mounting block (805) is provided on the inner side wall of the upper protection seat (1), and a drying plate (804) is slidably connected inside the mounting block (805), and the drying plate (804) corresponds to the filter screen (803).

10. A method for using the electronic transformer protection device according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1: The lower protective seat (3) is fixed as a whole at the position where it needs to be installed by means of a fixing plate (4), and then the electronic transformer body (2) is placed as a whole together with the connecting plate (6) inside the convex groove (7), and then the socket end of the wire is fixed by means of an elastic clamping sleeve (1102), and reinforced by adhesion with a traceless nano glue (1103), and finally the clamping block (1506) at the bottom of the upper protective seat (1) is engaged with the clamping groove (1503) on the upper surface of the lower protective seat (3), so that the L-shaped connecting rod (1507) passes through the interior of the limiting frame (1505), and the insertion rod A (1501) corresponds to the slot A (1508), and the slot B (1509) corresponds to the insertion rod B (1502) one by one; S2: The knob (10) is rotated again. Under the transmission connection of the transmission belt (13), the two sets of bidirectional threaded rods (14) rotate simultaneously. Under the threaded connection, the two sets of movable plates (9) move toward each other. When the tooth A (502) on the lower surface of the connecting block (12) meshes with the gear (504), the gear (504) is driven to rotate during the movement. Under the meshing connection between the gear (504) and the tooth B (506), the movable block (505) is slidably connected inside the receiving groove, so that the movable block (505) drives the positioning block (503) to move toward the positioning groove (508). At the same time, the elastic sleeve (502) above the connecting block (12) is engaged. 1102) drives the wire to move toward the socket seat (1104). When the elastic sleeve (1102) drives the guide joint end to be fully connected with the socket seat (1104), the positioning block (503) and the positioning groove (508) are fully engaged. Since the gear (504) extends to the outside of the connecting plate (6), the gear (504) is blocked by the side wall of the groove (501), thereby preventing the gear (504) from rotating under the action of the spring (507) and causing reset. At the same time, the lower surface of the connecting block (12) is fitted with the upper surface of the connecting plate (6) to perform bidirectional fixation, thereby enhancing the stability of the electronic transformer body (2) after being connected inside the lower protective seat (3); S3: During the process of the two groups of movable plates (9) moving toward each other, the insertion rod A (1501) and the insertion rod B (1502) also continuously approach the L-shaped connecting rod (1507), so that the insertion rod A (1501) is connected to the slot A (1508), and the insertion rod B (1502) is connected to the slot B (1509), thereby completing the overall fixation. By fixing the positions of the lower protective seat (3), the electronic transformer body (2) and the wires, the overall stability of the electronic transformer is improved; S4: After the installation is completed, the temperature sensor is started to sense the use of the electronic transformer in the protection device. When the temperature exceeds the preset temperature, a corresponding number of electric fans (802) are started according to the exceeding level, and the electronic transformer is cooled by the ventilation slot and the filter (803). The drying plate (804) is used to keep the inside of the protection device ventilated and dry, thereby improving the overall practicality of the protection device.
