For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] Combine the following Figure 1-6 The utility model is described to provide a transformer assembly tool.

[0036] like Figures 1 to 3 As shown, the transformer assembly tool 1 of the utility model includes: a tool base 11 and a positioning member 12; the tool base 11 has a column 111, and the column 111 is used to assemble the copper plate 2 and the coil of the transformer; the positioning member 12 is structured with a mounting groove 121, and a positioning hole 122 is provided at the bottom of the mounting groove 121; the positioning hole 122 is used to insert the pins of the copper plate 2.

[0037] It is easy to understand that the size of the column 111 in this embodiment is designed according to the magnetic core of the transformer to be assembled, so as to replace the magnetic core as a support for the copper plate 2 and the wire coil, and to be inserted into the copper plate 2 and the wire coil, and the copper plate 2 and the wire coil are pre-assembled so that the wire coil and the copper plate 2 can form a combination of the copper plate 2 and the wire coil on the column 111; at the same time, by providing a positioning member 12 and constructing a mounting groove 121 on the positioning member 12, when the copper plate 2 and the wire coil are assembled using the transformer assembly tool 1, the copper plate 2 and the wire coil are sleeved on the column 111, and the positioning member 12 is provided. The positioning piece 12 is located on one side of the column 111, so that at least a part of the copper plate 2 and the coil is located in the installation groove 121, so as to limit the position of the copper plate 2 and the coil as a whole; in addition, a positioning hole 122 is provided in the installation groove 121 to insert the pins of the copper plate 2, so as to fix the copper plate 2, so that the copper plate 2 can limit and fix the coil between the copper plates 2; after the assembly and fixation of the copper plate 2 and the coil are completed, the combination of the copper plate 2 and the coil can be removed from the column 111 as a whole through the positioning piece 12, so as to be mounted on the magnetic core of the transformer to be assembled.

[0038] The transformer assembly tool 1 of the utility model constructs a column 111 on the tool base 11 to replace the magnetic core, so that the copper plate 2 and the wire coil can be pre-assembled on the column 111, thereby avoiding the copper plate 2 and the wire coil being sequentially assembled on the magnetic core and scratching the magnetic core; at the same time, a positioning member 12 is provided on one side of the column 111, and the mounting groove 121 on the positioning member 12 can position the copper plate 2 and the wire coil as a whole, and the positioning hole 122 in the mounting groove 121 can further position and fix the copper plate 2, so that the copper plate 2 and the wire coil are It can always maintain the relative position of the final installation on the magnetic core, and the combination of the copper plate 2 and the wire coil can be removed from the column 111 as a whole through the positioning piece 12 so as to be mounted on the magnetic core of the transformer to be assembled, thereby improving the installation efficiency. At the same time, it is not easy to scratch the magnetic core to cause damage to the copper plate insulation layer and wire material, thereby damaging the performance and consistency of the transformer. It effectively solves the problem in the prior art that the wire coil and the copper plate are directly assembled on the magnetic core, resulting in low installation efficiency, and the magnetic core is easily scratched during the installation process, affecting the performance of the transformer.

[0039] Specifically, in some embodiments, Figure 3 and Figure 4 As shown, two opposite groove walls of the installation groove 121 have arc surfaces for abutting against the outer wall of the copper ring 21 of the copper plate 2 to support the copper plate 2 .

[0040] In this embodiment, the two relative groove walls of the mounting groove 121 have arc surfaces. When the transformer assembly tool 1 is used for assembly, the two relative groove walls of the mounting groove 121 can fit with the outer peripheral surface of the copper ring 21 of the copper plate 2 to limit and fix the copper ring 21, thereby supporting the copper plate 2 and making the copper plate 2 more stable in the mounting groove 121.

[0041] Specifically, in some embodiments, Figure 3 and Figure 4 As shown, a guide groove 1211 is provided at the bottom of the installation groove 121; a positioning hole 122 is provided at the bottom of the guide groove 1211; two opposite groove walls of the guide groove 1211 are respectively coplanar with the two side walls of the positioning hole 122 for abutting against the side walls of the pin.

[0042] In this embodiment, by providing a guide groove 1211 at the bottom of the installation groove 121, when the copper plate 2 is installed into the installation groove 121, the pin of the copper plate 2 is first aligned and inserted into the guide groove 1211, and the two opposite groove walls of the guide groove 1211 abut against the side walls of the pin, and the pin continues to be inserted along the guide groove 1211 until it is inserted into the positioning hole 122, which makes installation more convenient. After installation, the guide groove 1211 can also abut against the side wall of the part of the pin exposed outside the positioning hole 122, making the entire structure more stable and reliable.

[0043] In some embodiments, Figure 1 and Figure 2As shown, the transformer assembly tool 1 also includes a limiter 13, which is detachably arranged on the positioning member 12; the bottom structure of the column 111 has a limiter 1111; the limiter 13 is used to cooperate with the limiter 1111 to clamp the copper plate 2 and the wire coil.

[0044] In this embodiment, a limit member 13 is provided on the positioning member 12, and a limit portion 1111 is constructed at the bottom of the column 111. After the copper plate 2 and the wire coil are sleeved on the column 111 and the copper plate 2 is positioned on the positioning member 12, the limit member 13 and the limit portion 1111 are respectively abutted against the two ends of the assembly formed by the copper plate 2 and the wire coil to clamp and fix the assembly formed by the copper plate 2 and the wire coil, thereby constraining the axial size of the assembly formed by the copper plate 2 and the wire coil, so that the assembly formed by the copper plate 2 and the wire coil can meet the size requirements for installation on the magnetic core, and the size of the assembly formed by each copper plate 2 and the wire coil can be kept consistent, thereby improving the consistency of the final product.

[0045] Specifically, in some embodiments, Figures 1 to 3 As shown, the limiting member 13 is a U-shaped clamping member, and the two sides of the positioning member 12 are configured with clamping grooves 123 that are adapted to the two side walls of the U-shaped clamping member.

[0046] In this embodiment, after the copper plate 2 and the wire coil are sleeved on the column 111 and the pins of the copper plate 2 are inserted into the positioning holes 122 for positioning, the U-shaped groove of the U-shaped clip can be oriented toward the column 111, and the two side walls of the U-shaped clip can be aligned with the clip groove 123 and inserted into the clip groove 123, thereby fixing the U-shaped clip to the positioning member 12. At the same time, the U-shaped groove of the U-shaped clip surrounds the column 111 to relatively fix the positioning member 12 and the column 111, making the entire tooling structure more stable and facilitating assembly operations. The side surfaces of the U-shaped clip can cooperate with the limiting portion 1111 to clamp and fix the combination of the copper plate 2 and the wire coil.

[0047] Specifically, in some embodiments, Figures 1 to 3 , Figure 5 As shown, a positioning groove 1112 is constructed along the outer peripheral surface of the column 111 ; a part of the U-shaped clamping piece is clamped in the positioning groove 1112 and the clamping groove 123 .

[0048] In this embodiment, by constructing a positioning groove 1112 on the outer peripheral surface of the column 111, when the transformer assembly tool 1 is used for assembly, the positioning groove 1112 can be used to position the U-shaped clamping piece, so that the U-shaped clamping piece can cooperate with the limiting portion 1111 to clamp and fix the combination of the copper plate 2 and the wire coil, and constrain the axial size of the combination of the copper plate 2 and the wire coil, so that the combination formed by the copper plate 2 and the wire coil can meet the size requirements for installation on the magnetic core, and also make the size of each copper plate 2 and the combination formed by the wire coil consistent, thereby improving the consistency of the final product. Specifically, after the copper plate 2 and the wire coil are sleeved on the column 111, and the pins of the copper plate 2 are inserted into the positioning hole 122 for positioning, the position of the positioning piece 12 can be adjusted so that the clamping groove 123 and the positioning groove 1112 are located in the same plane, and then the U-shaped clamping piece is clamped with the clamping groove 123, and the U-shaped groove of the U-shaped clamping piece enters the positioning groove 1112.

[0049] It is understandable that the positions of the snap-in groove 123 and the positioning groove 1112 need to be determined according to the size of the assembly formed by the copper plate 2 and the coil in the transformer.

[0050] Optionally, there are two snap-in slots 123 and two positioning slots 1112.

[0051] In some embodiments, Figure 3 As shown, there are two clamping grooves 123 , and the clamping grooves 123 , the positioning holes 122 and the mounting groove 121 are all centrally symmetrically arranged about the center of the groove bottom of the mounting groove 121 .

[0052] In this embodiment, two snap-fit ​​grooves 123 are provided, and the snap-fit ​​grooves 123, the positioning holes 122 and the mounting grooves 121 are all symmetrical about the center of the bottom of the mounting grooves 121. After the positioning member 12 is flipped 180°, the relative positions of the snap-fit ​​grooves 123, the positioning holes 122 and the mounting grooves 121 remain unchanged, and the positioning function of the copper plate 2 can still be achieved, thereby preventing the installers from using the transformer assembly tool 1 to assemble the transformer, which may affect the position of the copper plate 2 and the size of the combination of the copper plate 2 and the wire coil due to the positioning member 12 being installed upside down. This prevents mistakes and has a good use effect.

[0053] In some embodiments, Figure 1 , Figure 2 and Figure 5 As shown, the limiting portion 1111 is a shoulder constructed on the column 111 .

[0054] In this embodiment, the limiting portion 1111 is the shoulder of the column 111. After the copper plate 2 and the wire coil are sleeved on the column 111, the shoulder of the column 111 can abut against one end of the combination of the copper plate 2 and the wire coil, and cooperate with the limiting member 13 to clamp and fix the combination of the copper plate 2 and the wire coil. The structure is simple and the use effect is good. The column 111 and the limiting portion 1111 can be integrally formed to simplify the production and assembly process, with high structural strength and good use effect.

[0055] In some embodiments, Figure 1 , Figure 2 and Figure 5 As shown, a plurality of columns 111 are spaced apart on the tooling base 11 ; the positioning members 12 are arranged correspondingly to the columns 111 .

[0056] In this embodiment, a plurality of columns 111 are spaced apart on the tooling base 11 , and each column 111 is provided with a corresponding positioning member 12 , so that a plurality of groups of copper plates 2 and wire coils can be assembled on the plurality of columns 111 at the same time to improve assembly efficiency.

[0057] Optionally, a plurality of columns 111 may be arranged in a row, and during assembly, the positioning members 12 are arranged on the sides of the columns 111 in a row to avoid mutual interference between the positioning members 12 .

[0058] Optionally, in some embodiments, the multiple columns 111 have different sizes so as to be inserted into copper plates 2 and wire cakes of different specifications.

[0059] In this embodiment, multiple columns 111 of different sizes are arranged on the tooling base 11 to adapt to copper plates 2 and coils of different specifications; so that the transformer assembly tool 1 of this embodiment can be suitable for the assembly of transformers of different specifications, which is more convenient and practical.

[0060] In a specific embodiment, the transformer includes: a magnetic core and a copper plate coil assembly wound on the magnetic core, the copper plate coil assembly includes a plurality of copper plates 2 and a coil; the copper plates 2 are arranged at intervals on the magnetic core, and a coil is arranged between two adjacent copper plates 2; the copper plates 2 and the coil can be assembled into a copper plate coil assembly by the transformer assembly tool 1 provided in any of the above embodiments. Specifically, Figure 6 As shown, the copper plate 2 includes a copper ring 21 with a notch and a first pin 22 and a second pin 23 arranged on both sides of the notch of the copper ring 21 ; the length of the first pin 22 is greater than the length of the second pin 23 .

[0061] In this embodiment, by setting the first pin 22 and the second pin 23 at the notch of the copper ring 21, the first pin 22 and the second pin 23 can respectively connect the first electrode and the second electrode to form a loop. Due to the internal design of the transformer, part of the copper plate 2 needs to be positively connected to the circuit board, and part of the copper plate 2 needs to be reversely connected to the circuit board, so the first pin 22 and the second pin 23 of the copper plate 2 need to be distinguished. The copper plate 2 of this embodiment has different lengths of the first pin 22 and the second pin 23 to distinguish the first pin 22 and the second pin 23, so that the copper plate 2 and the circuit board can be positively connected or reversely connected.

[0062] It is easy to understand that the positioning hole 122 on the positioning member 12 also needs to be arranged correspondingly according to the positions of the first pin 22 and the second pin 23 .

[0063] In a specific embodiment, Figures 1 to 6 As shown, the transformer includes four copper plates 2, and the four copper plates 2 are arranged in sequence of "two positive" and "two negative"; accordingly, four rows of positioning holes 122 are arranged on the positioning member 12, and each row of positioning holes 122 has two, which are respectively arranged corresponding to the first pin 22 and the second pin 23 of one of the copper plates 2, wherein the upper two rows of positioning holes 122 are biased to one side of the central axis of the positioning member 12, and are used for plugging the pins of the positively connected copper plate 2; the lower two rows of positioning holes 122 are biased to the other side of the central axis of the positioning member 12, and are used for plugging the pins of the reversely connected copper plate 2.

[0064] The above described embodiments are merely illustrative, and some or all of the modules may be selected according to actual needs to achieve the purpose of the embodiments. Those skilled in the art may understand and implement the embodiments without creative effort.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
