[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1 As shown:

[0023] An electronic low-voltage combined transformer comprises a half transformer body 1 and a half transformer body 2, wherein the half transformer body 1 and the half transformer body 2 are hinged to each other via a hinge shaft.

[0024] In this embodiment: In order to solve the technical problems existing in the prior art, as disclosed in the background technology above, "the current electronic low-voltage combination transformer is generally arranged in an open-close structure, and after the transformer is closed, it is fixed by screwing with bolts. This installation process is relatively troublesome, affecting the installation efficiency and the use effect is poor." In terms of use, this problem is obviously a real problem that is difficult to solve. In view of this, in order to solve this technical problem, a snap-on component 3 is added to this application document.

[0025] More specifically:

[0026] like Figure 1-Figure 3 As shown:

[0027] A clamping assembly 3 is installed between the half mutual inductor body 1 and the half mutual inductor body 2. The clamping assembly 3 includes a clamping seat 301 provided at one end of the half mutual inductor body 1 and a clamping plate 302 fixed to one end of the half mutual inductor body 2 near the clamping seat 301.

[0028] A U-shaped baffle 307 is slidably connected to the card holder 301;

[0029] When the half mutual inductor body 2 and the half mutual inductor body 1 are closed, the clamping plate 302 is clamped in the clamping seat 301, and the clamping plate 302 is limited and locked by the U-shaped baffle 307;

[0030] The holder 301 is fixed to the half-mutual inductor body 1 by bolts. The upper surface of the holder 301 is provided with symmetrically arranged strip grooves 304. The strip grooves 304 are provided with sliding rods 303. The two ends of the sliding rods 303 are fixedly connected to the holder 301. The surface of the sliding rod 303 is provided with a slider 306. The surface of the sliding rod 303 is provided with a spring 305. The two ends of the spring 305 are respectively fixedly connected to the slider 306 and the holder 301. The two ends of the U-shaped baffle 307 are fixedly connected to the two sets of sliders 306.

[0031] The slider 306 slides on the surface of the sliding rod 303 through the through hole;

[0032] The lower surface of the U-shaped baffle 307 is in contact with the upper surface of the clamping plate 302 .

[0033] In this embodiment, when the first half of the transformer body 1 and the second half of the transformer body 2 are closed and locked, the second half of the transformer body 2 is first flipped over. At this time, the second half of the transformer body 2 performs a circular motion with the hinge axis as the center, and then the second half of the transformer body 2 drives the clamping plate 302 to be clamped in the clamping seat 301 on the first half of the transformer body 1.

[0034] When the lever 302 is in the unlocked position, the spring 305 is pulled out of the unlocking position, and the spring 305 is pulled out of the unlocking position, so that the lever 302 is locked and the locking mechanism 307 is unlocked.

[0035] Going further;

[0036] In an optional embodiment, one side of the U-shaped baffle 307 is rotatably connected to a rotating shaft rod 308 via a bearing, and a baffle 309 is fixed to one end of the rotating shaft rod 308 away from the U-shaped baffle 307 .

[0037] In this embodiment, when the U-shaped baffle 307 moves to the end of the holder 301 away from the half-mutual inductor body 2, the baffle 309 on the rotating shaft rod 308 is rotated so that the baffle 309 is buckled on the outermost side of the holder 301. Through this operation, the U-shaped baffle 307 can be temporarily locked. During this process, when the wire is stuck between the half-mutual inductor body 1 and the half-mutual inductor body 2, there is no need to hold the U-shaped baffle 307 in the pulling operation all the time, which further improves the use effect of the device.

[0038] Going further;

[0039] In an optional embodiment, a slot 310 is provided on the upper surface of the card plate 302 . When the blocking piece 309 is stuck in the slot 310 of the card plate 302 , the spring 305 is in a compressed state.

[0040] In this embodiment: when the U-shaped baffle 307 is located at the position of the card plate 302, when it is flipped to the inside of the card slot 310 through the baffle 309, the spring 305 is in a compressed state, and the rebound force of the spring 305 drives the slider 306 and the U-shaped baffle 307 to move, and the U-shaped baffle 307 drives the rotating shaft rod 308 and the baffle 309 to move synchronously, so that the baffle 309 conflicts with the card plate 302, thereby increasing the stability of the U-shaped baffle 307 in the position of the card plate 302, making the U-shaped baffle 307 less likely to move, and improving the limit locking effect of the card plate 302.

[0041] The working principle and use process of the present invention are as follows: when the half transformer body 1 and the half transformer body 2 are closed and locked, the half transformer body 2 is first flipped over. At this time, the half transformer body 2 performs a circular motion with the hinge axis as the center, and then the half transformer body 2 drives the card plate 302 to be stuck in the card seat 301 on the half transformer body 1; before this, the U-shaped baffle 307 is pulled, and then the slider 306 is driven to slide on the surface of the sliding rod 303, and at the same time, the slider 306 drives the spring 305 to stretch until the U-shaped baffle is 307 moves to the end of the card seat 301 away from the half-mutual inductor body 2, and when the card plate 302 is stuck in the inside of the card seat 301, the U-shaped baffle 307 is then released, and then the spring 305 contracts and drives the slider 306 to slide on the sliding rod 303, and the slider 306 drives the U-shaped baffle 307 to reset. At this time, the U-shaped baffle 307 is located at the top of the card plate 302, thereby locking the card plate 302 in position, thereby completing the connection and locking of the half-mutual inductor body 1 and the half-mutual inductor body 2. Through this operation, this locking method is relatively fixed with respect to the bolt screw connection. In terms of installation method, this installation method is more convenient and faster, improves installation efficiency, and has a better use effect of this structure, which meets actual use needs; and when the U-shaped baffle 307 moves to the end of the card holder 301 away from the half-mutual inductor body 2, by rotating the baffle 309 on the shaft rod 308, the baffle 309 is buckled on the outermost side of the card holder 301. Through this operation, the U-shaped baffle 307 can be temporarily locked. In this process, when the wire is stuck in the position between the half-mutual inductor body 1 and the half-mutual inductor body 2, there is no need to hold the U-shaped baffle 307 in the pulling operation, which further improves the use of the device. When the U-shaped baffle 307 is located at the position of the card plate 302, it is flipped to the inside of the card slot 310 through the baffle 309. At this time, the spring 305 is in a compressed state, and the rebound force of the spring 305 drives the slider 306 and the U-shaped baffle 307 to move, and the U-shaped baffle 307 drives the rotating shaft rod 308 and the baffle 309 to move synchronously, so that the baffle 309 conflicts with the card plate 302, thereby increasing the stability of the U-shaped baffle 307 in the position of the card plate 302, making the U-shaped baffle 307 less likely to move, and improving the limit locking effect of the card plate 302.
