[0029] A mechanism for an electromagnetic coil assembly provided in the first embodiment of the present invention is shown in FIG. Figures 1 to 3 As shown, Figure 1 is a schematic structural diagram of an integrated electromagnetic coil assembly provided by an embodiment of the present invention, Figure 2 It is a schematic structural diagram of the inner wall 12 and the outer wall 13 in the integrated electromagnetic coil assembly provided in an embodiment of the present invention. Figure 3 It is a schematic diagram of the structure of the first conductive contact 5 and the second conductive contact 6 in the integrated electromagnetic coil assembly provided by an embodiment of the present invention. A mechanism for an electromagnetic coil assembly provided by the first embodiment of the present invention includes a support body 1, a channel 2, a head end hole 3 and a tail end hole 4. The channel 2 is arranged in the support body 1, and the channel 2 is spirally shaped around the center line 11 of the support body 1. The support body 1 is made of insulating material. The support body 1 includes an inner wall 12 and an outer wall 13. The inner wall 12, the outer wall 13 and the end faces 14 on both sides of the support body 1 enclose the channel 2. The channel 2 is used to place the conductor 9. The head end hole 3 and the tail end hole 4 are respectively arranged on the end face 14 on one side of the support body 1. The head end hole 3 and the tail end hole 4 are respectively connected to the channel 2. The head end hole 3 is used to place the first conductive contact 5, and the tail end hole 4 is used to place the second conductive contact 6. The first conductive contact 5 and the second conductive contact 6 are respectively connected to the conductor 9.

[0030] The hole 2 has a space inside to accommodate the conductor 9. The hole 2 presents a spiral shape around the center line 11 of the support body 1, which will make the conductor 9 inside the hole 2 also present a spiral shape around the center line 11 of the support body 1. The head end hole 3 has a space inside to accommodate the first conductive contact 5, and the tail end hole 4 has a space inside to accommodate the second conductive contact 6. The first conductive contact 5 and the second conductive contact 6 are both conductive materials, and the conductor 9 is electrically connected to the outside through the first conductive contact 5 and the second conductive contact 6 respectively.

[0031] The spiral channel 2 can increase the length of the conductor 9 and realize a more complex electromagnetic field distribution in a limited space, which helps to improve the induction strength and efficiency of the electromagnetic coil, and at the same time, a thinner conductor 9 can be made through a smaller channel 2. The support body 1 made of insulating material can provide an insulating layer for the conductor 9 located in the channel 2.

[0032] In this embodiment, a channel 2 is arranged in the support body 1, and the channel 2 is spirally shaped around the center line 11 of the support body 1. The support body 1 is made of insulating material. The inner wall 12 and the outer wall 13 in the support body 1 respectively enclose the channel 2 with the end faces 14 on both sides of the support body 1. The channel 2 is used to place the conductor 9. The end faces 14 on one side of the support body 1 are respectively provided with a head end hole 3 and a tail end hole 4. The head end hole 3 and the tail end hole 4 are respectively connected to the channel 2. The head end hole 3 is used to place the first conductive contact 5, and the tail end hole 4 is used to place the second conductive contact 6. The first conductive contact 5 and the second conductive contact 6 are respectively connected to the conductor 9. In this way, the conductive paste is injected into the hole 2 from the first port, so that the conductive paste completely fills the hole 2 in a spiral shape. After the conductive paste is solidified, a spiral conductor 9 is formed in the hole 2, and at the same time, a first conductive contact 5 is formed in the first end hole 3, and a second conductive contact 6 is formed in the tail end hole 4. The first conductive contact 5 and the second conductive contact 6 are respectively connected to the conductor 9, and then the external circuit is respectively connected to the first conductive contact 5 and the second conductive contact 6. Then, the support body 1 is solidified to form a high-strength conductor 9 structure. The solidification of the support body 1 in the spiral hole forms a high-strength spiral conductor 9 structure, which is beneficial to improve the reliability of the electromagnetic coil assembly. Thereby, the technical effect of avoiding wire breakage during the process of winding the electromagnetic coil and the process of use is achieved, and at the same time, the reliability of the overall structure is improved.

[0033] As an implementation mode, a mechanism for an electromagnetic coil assembly provided in Example 1 of the present invention further includes a first straight hole 7 and a second straight hole 8, wherein the first straight hole 7 is connected to the head hole 3 and the channel 2 respectively, and the second straight hole 8 is connected to the tail hole 4 and the channel 2 respectively, and the length extension direction of the first straight hole 7 is parallel to the center line 11 of the support body 1, and the length extension direction of the second straight hole 8 is parallel to the center line 11 of the support body 1. When the conductive paste is injected into the spiral channel 2 through the head hole 3, the conductive paste will first smoothly enter the interior of the channel 2 from the first straight hole 7, which is conducive to reducing the flow resistance of the conductive paste and improving the filling efficiency. At the same time, when the conductive paste is discharged from the tail hole 4, the conductive paste can also smoothly enter the tail hole 4 from the second straight hole 8. After the conductive paste is cured, a high-strength spiral conductor 9 is formed inside the spiral channel 2 and is connected to the first conductive contact 5 in the head hole 3 through the first straight hole 7 and to the second conductive contact in the tail hole 4 through the second straight hole 8 .

[0034] In some embodiments, the outer side wall 13 and the inner side wall 12 are respectively cylindrical. Observed along the direction of the center line 11 of the support body 1, the end faces 14 on both sides of the support body 1 are respectively annular. The cylindrical outer side wall 13 and the inner side wall 12 will make the support body 1 have better structural stability and anti-deformation ability. At the same time, the annular end face 14 cooperates with the spiral channel 2, which is conducive to enhancing the reliability of the electromagnetic coil assembly. When the conductive slurry is cured in the spiral channel 2 to form the conductor 9, the above-mentioned stable support structure can effectively prevent the conductor 9 from being deformed or broken when subjected to external force.

[0035] In some embodiments, the length of the channel 2 along the center line 11 of the support body 1 is less than the spacing between the end faces 14 on both sides of the support body 1, that is, assuming that the length of the channel 2 along the center line 11 of the support body 1 is H1, and the spacing between the end faces 14 on both sides of the support body 1 is H2, then H1<H2. By limiting the length of the channel 2 along the center line 11 of the support body 1 to between the end faces 14 on both sides of the support body 1, the support body 1 is wrapped around the outside of the conductor 9 located in the channel 2, the outside of the conductor 9 is insulated, and the yield and consistency of the product are improved at the same time.

[0036] In order to explain the integrated electromagnetic coil assembly provided by the present invention in detail, the above-mentioned embodiment 1 explains in detail a mechanism for the electromagnetic coil assembly. Based on the same inventive concept, the present application also provides an integrated electromagnetic coil assembly, see embodiment 2 for details.

[0037] The second embodiment of the present invention provides an integrated electromagnetic coil assembly, including the above-mentioned mechanism for the electromagnetic coil assembly. The second embodiment of the present invention provides an integrated electromagnetic coil assembly further including a conductor 9, a first conductive contact 5 and a second conductive contact 6. The conductor 9 is arranged inside the channel 2, the first conductive contact 5 is arranged inside the head end hole 3, and the second conductive contact 6 is arranged inside the tail end hole 4, wherein one end of the conductor 9 passes through the first straight hole 7 to connect with the first conductive contact 5, and the other end of the conductor 9 passes through the second straight hole 8 to connect with the second conductive contact 6. By injecting the conductive paste from the head end hole 3 into the inside of the spiral channel 2, it is ensured that the paste completely fills the spiral channel 2. After the paste is cured, a high-strength spiral conductor 9 will be formed in the channel 2. At the same time, in the head end hole 3 and the tail end hole 4, the conductive paste is also cured to form the first conductive contact 5 and the second conductive contact 6, and the two ends of the conductor 9 will pass through the first straight hole 7 and the second straight hole 8, respectively, and are tightly connected with the first conductive contact 5 and the second conductive contact 6, forming a complete and stable circuit path. Then, the external circuit is connected to the first conductive contact 5 and the second conductive contact 6 respectively, so that the function of the electromagnetic coil assembly can be realized.

[0038] In some embodiments, the outer diameter of the conductor 9, the outer diameter of the first conductive contact 5, and the outer diameter of the second conductive contact 6 are all the same. The same outer diameter of the conductor 9, the outer diameter of the first conductive contact 5, and the outer diameter of the second conductive contact 6 make the inner diameter of the channel 2, the inner diameter of the head end hole 3, the inner diameter of the tail end hole 4, the inner diameter of the first straight hole 7, and the inner diameter of the second straight hole 8 all the same, which is conducive to simplifying the manufacturing process and reducing manufacturing costs, improving production efficiency, and reducing scrap rate.

[0039] In this embodiment, the support body 1 serves as a skeleton, and a spiral channel 2 is arranged inside the support body 1 around the center line 11 of the support body 1. The conductive slurry is injected into the channel 2 from the first port so that the conductive slurry completely fills the spiral channel 2. After the conductive slurry is cured, a spiral conductor 9 is formed in the channel 2, that is, a coil is formed in the support body 1 serving as a skeleton. At the same time, a first conductive contact 5 is formed in the first end hole 3, and a second conductive contact 6 is formed in the tail end hole 4. The first conductive contact 5 and the second conductive contact 6 are respectively connected to the conductor 9, and then the external circuit is respectively connected to the first conductive contact 5 and the second conductive contact 6. Then, a high-strength conductor 9 structure is cured in the support body 1. The curing of the support body 1 in the spiral hole forms a high-strength spiral conductor 9 structure, which is beneficial to improving the reliability of the electromagnetic coil assembly.

[0040] In order to explain in detail a method for preparing an electromagnetic coil assembly provided by the present invention, the above-mentioned embodiment one explains in detail a mechanism for an electromagnetic coil assembly. Based on the same inventive concept, the present application also provides a method for preparing an electromagnetic coil assembly, see embodiment three for details.

[0041] See also Figure 4 , Figure 4 : is a flow chart of a method for preparing an electromagnetic coil assembly provided by an embodiment of the present invention. Embodiment 3 of the present invention provides a method for preparing an electromagnetic coil assembly, and the method for preparing an electromagnetic coil assembly comprises the following steps:

[0042] Step S100, forming a channel 2 in the support body 1 and forming a head end hole 3 and a tail end hole 4 on the end surface 14 of one side of the support body 1, wherein the channel 2 is spirally shaped around the center line 11 of the support body 1, and the head end hole 3 and the tail end hole 4 are respectively connected to the channel 2;

[0043] The support body 1 can be made of insulating materials such as ceramics and plastics to ensure that there will be no leakage or rupture during the operation of the electromagnetic coil.

[0044] Step S200, injecting the conductive paste from the first port into the channel 2 according to a preset pressure value, and the conductive paste in the channel 2 is discharged through the rear port to solidify in the channel 2 to form a conductor 9;

[0045] The conductive paste may be silver paste, copper paste or other metal-based conductive pastes.

[0046] Step S300 , forming a first conductive contact 5 in the first port, and forming a second conductive contact 6 in the second port, wherein the first conductive contact 5 and the second conductive contact 6 are connected to the conductor 9 , respectively.

[0047] In some embodiments, the support body 1 can be manufactured by stacking molding, and the support body 1 is made of insulating materials. For example, insulating materials including but not limited to ceramic powder, plastic particles or special composite materials can be selected as raw materials for stacking molding, and then stacking molding technology is used to stack and compact the above materials layer by layer to form a solid and dense support body 1 structure, and form a channel 2, a head end hole 3, a tail end hole 4, a first straight hole 7 and a second straight hole 8 on the support body 1. The thickness, density and uniformity of the support body 1 can be accurately controlled by the stacking molding technology to ensure the quality and performance of the final product.

[0048] In some embodiments, a channel 2 is formed in the support body 1, and a head hole 3 and a tail hole 4 are formed on the end surface 14 of one side of the support body 1, and a channel 2 and a first straight hole 7 and a second straight hole 8 are formed near the end surface 14 in the support body 1, respectively. The first straight hole 7 and the second straight hole 8 are connected to the channel 2, respectively. The length extension direction of the first straight hole 7 is parallel to the center line 11 of the support body 1, and the length extension direction of the second straight hole 8 is also parallel to the center line 11 of the support body 1. A head hole 3 and a tail hole 4 are formed on the end surface 14 of one side of the support body 1, respectively. The head hole 3 is connected to the first straight hole 7, and the tail hole 4 is connected to the second straight hole 8. By forming the channel 2, the head hole 3, the tail hole 4, the first straight hole 7 and the second straight hole 8, a good channel and support structure can be provided for the injection and curing of the conductive paste, ensuring that the conductive paste can completely fill the interior of the spiral channel 2 and form a high-strength spiral structure conductor 9.

[0049] In some embodiments, injecting the conductive slurry from the first port into the channel 2 according to a preset pressure value includes injecting the conductive slurry into the channel 2 through the first port through a pipe using a glue dispenser according to a preset pressure value. For example, the conductive slurry and glue dispenser equipment prepared in advance can be used to accurately control the pressure, flow rate and injection speed of the glue dispenser equipment to ensure that the conductive slurry can be injected according to the preset parameters. It should be noted that the preset pressure value can be set according to the performance of the conductor 9 actually prepared, such as the pressure value needs to ensure that the conductive slurry completely fills the interior of the spiral channel 2, and as the conductive slurry is continuously injected, the conductive slurry will flow along the channel 2 and gradually fill the entire channel 2. The internal space. When the conductive slurry is discharged from the tail port, it means that the interior of the channel 2 has been completely filled with the conductive slurry. This not only avoids the unevenness, bubbles, etc. that may be caused by traditional manual injection, but also ensures that the conductive slurry can be tightly filled in the channel 2 and achieve a good curing effect, which is beneficial to improve the conductivity and reliability of the electromagnetic coil assembly.

[0050] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
