[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 The present invention provides the following technical solution: a magnetic integrated LLC transformer with a connector locking structure, including a base plate 1, a magnetic ring 2 installed on the surface of the base plate 1, and a lead 3 at the bottom of the magnetic ring 2 passing through the base plate 1 and connecting to a connector 4. The above parts together constitute the magnetic integrated LLC transformer mentioned in the present technical solution.

[0022] A kit 5 is fitted onto the outer wall of lead 3;

[0023] The bottom of the kit 5 is fixedly connected to a sheath 6. The inner wall of the connection end between the kit 5 and the sheath 6 is fitted with an internal threaded sleeve 7. The bottom of the internal threaded sleeve 7 is connected to a compression block 8. One side of the compression block 8 is connected to the outer wall of the lead wire 3.

[0024] Preferably, a limiting ring 9 is fixedly connected to the bottom of the connector 4 and the lead wire 3 socket end, and the inner diameter of the limiting ring 9 is smaller than the inner diameter of the cylindrical sleeve end of the connector 4.

[0025] In actual use, before the connector 4 is connected to the lead wire 3, the kit 5, the sheath 6 and the internal thread sleeve 7 will be pre-fitted onto the lead wire 3. The kit 5 and the sheath 6 are made of insulating material, and the sheath 6 and the lead wire 3 are connected by an interference fit.

[0026] In this way, the sheath 6 can provide safety protection for the connection between the connector 4 and the lead wire 3 during use.

[0027] Preferably, the top of the extrusion block 8 is fixedly connected to a top block 81, and the bottom of the extrusion block 8 is fixedly connected to a bottom block 82;

[0028] The outer wall of the top block 81 is an arc-shaped structure, and a threaded structure is provided on the arc-shaped outer wall of the top block 81. One side of the bottom block 82 is provided with a chamfered surface, and the other side of the outer wall of the bottom block 82 is an arc-shaped structure.

[0029] In practical use, when the pressing block 8 is inserted into the gap between the connector 4 and the lead wire 3, the bottom block 82 of the pressing block 8 is first inserted into the opening between the connector 4 and the lead wire 3. Then, a small tool is used to tap the top block 81 of the pressing block 8. In this way, the bottom block 82 of the pressing block 8 will gradually enter the gap between the connector 4 and the lead wire 3 through the beveled surface on one side.

[0030] When the bottom of the base block 82 comes into contact with the limiting ring 9, the operation stops, thus effectively installing the compression block 8 between the connector 4 and the lead wire 3.

[0031] Preferably, the extrusion block 8 is made of metal, and four extrusion blocks 8 are equally spaced between the connector 4 and the lead wire 3. The internal thread sleeve 7 is connected to the four top blocks 81 on the four extrusion blocks 8 by a threaded locking structure.

[0032] In practical use, when connecting lead 3 to connector 4, lead 3 must first be inserted into the preset position of connector 4.

[0033] Next, in order to further enhance the stability and security of the connection, four compression blocks 8 need to be inserted into the gap between the lead wire 3 and the connector 4. This step ensures a tight fit between the two.

[0034] Once the lead wire 3 and connector 4 are connected, the next crucial step is the locking process: at this point, the internal threaded sleeve 7 needs to be slowly adjusted to the appropriate position and threadedly engaged and locked with the top block 81 on the four pressing blocks.

[0035] This innovative connection method completely eliminates the destructive operation of squeezing the connector 4 to lock the lead 3, which is a traditional method. This not only greatly improves the convenience of operation but also significantly enhances the reliability and durability of the connection. More importantly, this design makes the maintenance or replacement of the lead 3 and connector 4 extremely simple, eliminating the hassle of disassembly and thus effectively reducing maintenance costs and improving work efficiency.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
