[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figure 1-4 As shown, the present invention is an inverter inductor using film-clad aluminum wire, comprising:

[0036] The housing 2 is located at the top of the base plate 1. The housing 2 has an outer wire tube 3 inside, and an inner wire tube 5 is slidably connected inside the outer wire tube 3.

[0037] The top cover 7 is connected to the top end of the inner tube 5 of the wire. The inner concave tube 11 and the wiring tube 9 pass through the inside of the top cover 7. The bottom end of the inner concave tube 11 is connected to the inner tube 5 of the wire.

[0038] An inductor coil 12 is provided at the bottom of the top cover 7. The two ends of the inductor coil 12 are fixedly connected to the top cover 7 through the baffle 6. The inductor coil 12 is made of film-wrapped flat aluminum wire.

[0039] The top ends of the concave tube 11 and the connecting tube 9 are respectively connected to the two ends of the arc-shaped conductor tube 10.

[0040] Specifically, during the assembly of the inverter inductor, the inductor coil 12 is fixed to the bottom of the top cover 7 via the top of the baffle 6. The wiring of the inductor coil 12 is passed through the wiring tube 9, and then through the wiring tube 9, the arc-shaped wire tube 10, and the concave tube 11 to the inner wire tube 5. Next, the wiring is passed through the outer wire tube 3. Then, the inner wire tube 5 is inserted into the outer wire tube 3. The top cover 7 is pressed down, and the inner wire tube 5 slides down along the outer wire tube 3, which facilitates the stable entry of the inductor coil 12 into the housing 2.

[0041] The inductor coil 12 is wound with film-coated flat aluminum wire instead of traditional enameled flat copper wire, which reduces the weight of the inductor coil 12, lowers the product cost, facilitates the movement and installation of the inductor coil 12, and improves production efficiency.

[0042] In one embodiment of the present invention, a guide mechanism is provided on the side wall of the housing 2, and the baffle 6 is slidably connected to the groove of the guide mechanism.

[0043] In one embodiment of the present invention, the guiding mechanism includes:

[0044] The elastic pad 18 is configured as a long strip pad structure, and one side of the elastic pad 18 is fixedly connected to the inner wall of the housing 2.

[0045] There are two side guide plates 17, which are located on both sides of the elastic pad 18. The space enclosed by the side guide plates 17 and the elastic pad 18 is the slide groove of the guide mechanism.

[0046] For details, please refer to Figure 2-3 As shown, the guide mechanism inside the housing 2 guides the downward movement of the baffle 6. The baffle 6 slides in the groove formed by the side guide plate 17 and the elastic pad 18 to prevent the baffle 6 from tilting during the downward movement.

[0047] In one embodiment of the present invention, a support rod 20 is provided on the inner wall of the housing 2, and a guide roller 19 is provided on the inner side of the support rod 20. The guide roller 19 is located on one side of the baffle 6.

[0048] For details, please refer to Figure 2-3 As shown, when the baffle 6 moves downward, the guide rollers 19 on the other two sides inside the housing 2 roll on the side wall of the baffle 6. Through the groove and the guide rollers 19, the baffle 6 is guided in different directions when it moves downward, which further ensures the stable movement of the baffle 6.

[0049] In one embodiment of the present invention, the guide roller 19 is configured as an elastic rubber wheel.

[0050] Specifically, the guide roller 19, which is set as an elastic rubber wheel, can play a certain role in shock absorption on both sides of the baffle 6.

[0051] In one embodiment of the present invention, the bottom end of the baffle 6 is provided with an embedding mechanism 13, and the inner side of the bottom plate 1 is provided with an embedding groove 14 corresponding to the embedding mechanism 13.

[0052] Specifically, the baffle 6 moves to the bottom plate 1, and the embedding mechanism 13 at the bottom of the baffle 6 is embedded into the embedding groove 14, so that the baffle 6 is stably installed and avoids the baffle 6 from tilting during use.

[0053] In one embodiment of the present invention, please refer to Figure 4 As shown, the embedding mechanism 13 includes:

[0054] An extension embedding block 1301 is fixedly connected to the bottom end of the baffle 6 at a position corresponding to the embedding groove 14.

[0055] An outer fixing plate 1302 is fixedly connected to the outside of the extended embedded block 1301;

[0056] The bottom end of the outer sliding plate 1304 of the embedded block is connected to the outer sliding plate 1302 of the embedded block through the embedded block spring 1303. The outer sliding plate 1304 of the embedded block is slidably connected to the outer side of the extended embedded block 1301.

[0057] Specifically, when the baffle 6 moves to the bottom plate 1, the extended insert block 1301 at the bottom of the baffle 6 is inserted into the insert groove 14, so that the baffle 6 is stably fixed and avoids the baffle 6 from tilting during use. At the same time, the bottom end of the insert block outer sliding plate 1304 abuts against the bottom plate 1, and the top end of the insert block outer sliding plate 1304 is connected to the insert block outer fixing plate 1302 through the insert block spring 1303. The insert block spring 1303 dampens the fixed position of the baffle 6.

[0058] In one embodiment of the present invention, a heat-conducting plate 16 is provided at the top of the base plate 1, and a heat-conducting extension plate 15 is fixedly connected to the bottom end of the heat-conducting plate 16. The heat-conducting extension plate 15 passes through the interior of the base plate 1 and extends to the outside of the base plate 1.

[0059] Specifically, various inverters have inductors that generate a lot of heat, and the accumulation of heat will reduce the efficiency of the inductors or damage them. The heat conduction plate 16 is located below the inductor coil 12. The heat conduction plate 16 can conduct the heat from the inductor coil 12, which has a high temperature inside the housing 2, to the outside of the housing 2 through the heat conduction extension plate 15, which facilitates heat dissipation inside the housing 2.

[0060] In one embodiment of the present invention, a heat dissipation fin 8 is provided through the interior of the top cover 7, and a plurality of heat dissipation fins 8 are provided, which are distributed in a rectangular array inside the top cover 7.

[0061] Specifically, if the heat inside the housing 2 is transferred upwards, the heat at the top of the housing 2 is transferred to the outside of the top cover 7 through the heat dissipation fins 8, which facilitates heat dissipation above the inductor coil 12 inside the housing 2.

[0062] In one embodiment of the present invention, the bottom end of the inner tube 5 of the conductor is connected to an annular rubber ring 4, and the outer side of the annular rubber ring 4 is slidably connected to the inner wall of the outer tube 3 of the conductor; the bottom end of the outer tube 3 of the conductor passes through the interior of the base plate 1.

[0063] Specifically, the arrangement of the inner tube 5 and the outer tube 3 affects the wiring of the coil. At the same time, the annular rubber ring 4 can fill the gap between the inner tube 5 and the outer tube 3. The bottom end of the outer tube 3 passes through the base plate 1, which facilitates the lead-out of the coil wiring and makes the coil wiring easier.

[0064] The working principle of this invention is as follows: During the assembly of the inverter inductor, the inductor coil 12 is fixed to the bottom end of the top cover 7 through the top end of the baffle 6. The wiring of the inductor coil 12 is passed through the wiring tube 9, and then through the wiring tube 9, the arc-shaped wire tube 10 and the concave tube 11 to the inner wire tube 5. Then the wiring is passed through the outer wire tube 3. The inner wire tube 5 is then inserted into the outer wire tube 3. The top cover 7 is pressed down, and the inner wire tube 5 slides down along the outer wire tube 3, which facilitates the stable entry of the inductor coil 12 into the housing 2.

[0065] The guide mechanism inside the housing 2 guides the downward movement of the baffle 6. The baffle 6 slides within the groove formed by the side guide plate 17 and the elastic pad 18, preventing the baffle 6 from tilting during its downward movement. At the same time, when the baffle 6 moves downward, the guide rollers 19 on the other two sides inside the housing 2 roll on the side wall of the baffle 6. Through the groove and the guide rollers 19, the baffle 6 is guided in different directions during its downward movement, further ensuring the stable movement of the baffle 6.

[0066] When the baffle 6 moves to the bottom plate 1, the extended insert block 1301 at the bottom of the baffle 6 is inserted into the insert groove 14, so that the baffle 6 is stably fixed and avoids the baffle 6 from tilting during use. At the same time, the bottom end of the insert block outer sliding plate 1304 abuts against the bottom plate 1, and the top end of the insert block outer sliding plate 1304 is connected to the insert block outer fixing plate 1302 through the insert block spring 1303. The insert block spring 1303 dampens the fixed position of the baffle 6.
