[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] Figure 1 It is a structural schematic diagram of a preferred embodiment of the fixture base of the present utility model. Figure 2 It is a structural schematic diagram of a transformer module to which the fixture base of the utility model is applicable. Figure 3 yes Figure 2 The transformer module shown is placed on the structural schematic diagram of the fixture base of the present invention. Figure 1 The fixture base 100 shown can be used for Figure 2 The transformer module 200 is shown.

[0023] like Figure 2As shown, the transformer module 200 includes a PCBA 210 and an inductor box 220. The PCBA 210 includes a PCB board 211 and an inductor and a cable 212 soldered on the PCB board 211. Figure 2 As shown, the inductor is soldered to the first side of the PCB board 211, and the cable 212 is soldered to the second side of the PCB board 211 and extends in a direction away from the first side, with the first side facing away from the second side. The inductor box 220 is mounted on the inductor.

[0024] like Figure 1 As shown, the fixture base 100 of the present invention includes a base body 110 for placing the PCBA 210 to be packaged. A first sub-support block 121 and a second sub-support block 122 are respectively provided at the center of the two ends of the first side surface 111 of the base body 110 facing away from the PCBA 210 along its length direction. The second side surface of the base body 110 supports the PCB board 211 of the PCBA, that is, the second side surface of the base body 110 contacts the second side surface of the PCB board 211 to support the PCB board 211. Part of the line segments of the first outer side 112 of the base body 110 are recessed inward to form a plurality of cable avoidance grooves 131, 132 and 133, and the plurality of cable avoidance grooves 131, 132 and 133 are located between the first sub-support block 121 and the second sub-support block 122. Inward recess here refers to recessing from the first outer side 112 toward its opposite side. As shown Figure 3 As shown, each cable avoidance groove 131, 132 and 133 faces a group of cables 212. The depths of the cable avoidance grooves 131, 132 and 133 are equal and preferably match the thickness of the cables.

[0025] Figure 3 yes Figure 2 The transformer module shown is placed on the structural schematic diagram of the fixture base of the present invention. Figure 4 yes Figure 3 The transformer module and the fixture base are shown as a schematic diagram after being flipped over; Figure 5 It is adopted Figure 1 Jig base placement shown Figure 2 The flow chart of the transformer module is shown in the figure. Figure 1-5 The principle and use of the fixture base of the present invention are described as follows. Since the inductor and the inductor box located on the first side of the PCB board 211 are relatively heavy, and the cable located on the second side of the PCB board 211 is usually of a certain length, if the conventional method of placing the inductor at the bottom and the cable at the top is used, it is easy to cause the PCB board 211 to deform or even crack, and the cable to bend and be damaged. Therefore, in order to solve this technical problem, the present application cleverly designed the aforementioned fixture base 100. Figure 5 As shown, the PCBA 210 to be packaged is placed on the second side of the base 110 (as shown in FIG. Figure 3 Then, the PCBA 210 and the base 110 are turned over so that the PCBA 210 faces upward and the base 110 faces downward (as shown). Figure 4 (As shown). The inductor box 220 is then placed over the PCBA 210 from top to bottom through the opening of the inductor box 220 until the inductor box 220 contacts the second side surface of the base. This prevents deformation or even cracking of the PCB 211 during handling and transport, as the base 110 supports the PCB 211, the inductor, and the inductor box. Furthermore, the cable escape groove cleverly prevents compression of the cable 212. Furthermore, the first and second sub-support blocks 121, 122 provide space for the cable 212 to extend freely, preventing the cable 212 from bending and being damaged during transport.

[0026] Of course, those skilled in the art will appreciate that, in addition to the aforementioned embodiments, in preferred embodiments of the present invention, any number of support blocks may be provided at any location on the first side 111 of the base 110 facing away from the PCBA 210. Cable escape slots may also be implemented by providing slits or through-holes at any location on the base 110 facing the cables of the PCBA, all of which fall within the scope of protection of the present invention.

[0027] In other preferred embodiments of the present invention, the base 110, the PCB board 211 and the inductor box 220 can be any other suitable shapes, such as a square or a racetrack shape, as long as they can match each other.

[0028] In a preferred embodiment of the present invention, the lengths of the cable avoidance slots 131, 132, and 133 can be equal or different, and they match the number and width of the corresponding set of cables. The shape of the base 110 matches the shape of the PCB board 211 and the inductor box 220, that is, Figure 1-3As shown, the base 110 is rectangular, the PCB is a rectangular plate, and the inductor box 220 is a rectangular box with a rectangular opening. The surface area of ​​the second side surface of the base 110, where the PCBA 210 is placed, is greater than the surface area of ​​the rectangular opening of the inductor box 220. The surface area of ​​the opening of the inductor box 220 is greater than the surface area of ​​the PCB 211 of the PCBA 210. Preferably, the distance between the first and second sub-support blocks 121, 122 and the first outer side 112 is greater than the depth of the cable avoidance grooves 131, 132, and 133. To accommodate the transformer module, in a preferred embodiment of the present invention, the base 110 has a thickness of 9 to 11 mm, the height of the first and second sub-support blocks is 35 to 45 mm, the width of the first and second sub-support blocks is 75 to 85 mm, and the distance between the first and second sub-support blocks and the first outer side 112 is 25 to 45 mm. Of course, in other preferred embodiments of the present invention, any other sizes may be used, which all fall within the protection scope of the present invention.

[0029] The jig base of the present invention utilizes a base body to support the PCB, thereby preventing deformation or even cracking of the PCB. It also cleverly utilizes cable relief grooves to prevent cable compression, and the support blocks provide space for the cables to extend freely, preventing them from bending and damage during transportation. Furthermore, by recessing a portion of the first outer edge of the base body inward to form multiple cable relief grooves between the two support blocks, this not only facilitates processing and saves materials, but also ensures the stability of the base body. Furthermore, through specific dimensional design, the jig base can be more widely applicable to common transformer modules currently on the market.

[0030] In addition to being applicable to transformer modules, the fixture base of the present invention can also be applied to any other similar modules, such as capacitor modules. Figures 1 to 4As can be seen from the illustrated embodiment, the present invention further provides a fixture base, including a base body 110 for placing a PCBA, wherein the PCBA can be any suitable known PCBA, which includes a PCB board, electronic devices (such as an inductor) and cables arranged on the PCB board. The base body 110 is provided with a first sub-support block 121 and a second sub-support block 122 on the first side 111 facing away from the PCBA 210. The second side of the base body 110 supports the PCB board of the PCBA, that is, the second side of the base body 110 contacts the second side of the PCB board to support the PCB board 211. The first side faces away from the second side. A plurality of cable avoidance grooves 131, 132 and 133 are correspondingly provided on the base body 110 at positions facing the cables of the PCBA.

[0031] Here, the shape of the base body 110 matches the shape of the PCB board of the PCBA, for example, it can be a rectangle as described above. As described above, the first sub-support block 121 and the second sub-support block 122 can be arranged at the center of the two ends of the first side surface 111 of the PCBA 210 along its length. Partial segments of the first outer side 112 of the base body 110 are recessed inward to form the multiple cable avoidance grooves 131, 132, and 133, and the multiple cable avoidance grooves 131, 132, and 133 are located between the first sub-support block 121 and the second sub-support block 122. The distance between the first sub-support block 121 and the second sub-support block 122 and the first outer side 112 is greater than the depth of each cable avoidance groove 131, 132, and 133.

[0032] Preferably, the base body 110 is a rectangular base body 110, and the PCB board is a rectangular board. The surface area of ​​the rectangular base body is larger than the surface area of ​​the opening of the packaging box for packaging the PCBA, and the surface area of ​​the opening of the packaging box is larger than the surface area of ​​the rectangular board. Preferably, the distance between the first sub-support block 121 and the second sub-support block 122 and the first outer side 112 is larger than the depth of each cable avoidance groove 131, 132 and 133. In order to adapt to the transformer module, in a preferred embodiment of the present utility model, the thickness of the base body 110 is 9 to 11 mm, the height of the first sub-support block and the second sub-support block is 35 to 45 mm, the width of the first sub-support block and the second sub-support block is 75 to 85 mm, and the distance between the first sub-support block and the second sub-support block and the first outer side 112 is 25 to 45 mm.

[0033] The jig base of the present invention uses the base body to support the PCB, thereby preventing deformation or even cracking of the PCB. It also cleverly employs cable relief grooves to prevent cable compression. The support blocks provide space for the cables to extend freely, preventing them from bending and damage during transport. Furthermore, by recessing a portion of the first outer edge of the base body inward to form multiple cable relief grooves between the two support blocks, this not only facilitates processing and saves material, but also ensures the stability of the base body.

[0034] Although the present invention is described through specific embodiments, those skilled in the art will appreciate that various modifications and equivalent substitutions may be made to the present invention without departing from the scope of the present invention.
