[0024] The embodiment of the utility model is described in further detail below in combination with the drawings and examples. The following examples are used to illustrate the utility model, but cannot be used to limit the scope of the utility model.

[0025] As Figures 1 to 6As shown, a plastic insulated laminated copper bar structure includes an insulating plate 1 and a first copper bar 2. The front side of the insulating plate 1 is provided with the first copper bar 2 and a second copper bar 3, and the back side of the insulating plate 1 is provided with a third copper bar 4 and a fourth copper bar 5, respectively. The first copper bar 2 and the second copper bar 3 are hot-pressed with a first insulating layer 6 on the side surface away from the insulating plate 1, and the third copper bar 4 and the fourth copper bar 5 are hot-pressed with a second insulating layer 7 on the side surface away from the insulating plate 1. The material of the insulating plate 1 can be glass fiber. The glass fiber plate has high insulation, high temperature resistance, and high mechanical and dielectric properties, and is suitable for high temperature environment under large current application in servers. The materials of the first insulating layer and the second insulating layer can be PET. PET has high strength and wear resistance, and is suitable for protecting the internal copper bars and insulating plates. The two ends of the first copper bar 2, the second copper bar 3, the third copper bar 4 and the fourth copper bar 5 are connected and mounted with a press-in nut 8 for electrical connection with the connected electronic components. The insulating plate 1 is provided with a fixing nut 9 at both ends for fixing the laminated copper bar structure. The fixing nut 9 is electrically isolated from the first copper bar 2, the second copper bar 3, the third copper bar 4 and the fourth copper bar 5. The insulating plate 1 and the first insulating layer 6 and the second insulating layer 7 are covered with a shielding copper foil 10 on the outside to shield the electromagnetic waves generated by the first copper bar 2, the second copper bar 3, the third copper bar 4 and the fourth copper bar 5 when conducting current, so as not to interfere with the operation of other electronic components in the server. Especially when the first copper bar 2, the second copper bar 3, the third copper bar 4 and the fourth copper bar 5 are used to transmit alternating current, the electromagnetic interference caused is greater. The shielding copper foil 10 is wrapped outside the first copper bar 2, the second copper bar 3, the third copper bar 4 and the fourth copper bar 5 (except for the area near the two ends of the press-in nut 8), which can achieve electromagnetic shielding effect. The shielding copper foil 10 is electrically insulated from the first copper bar 2, the second copper bar 3, the third copper bar 4 and the fourth copper bar 5 through the insulating plate 1 and the first insulating layer 6 and the second insulating layer 7. The front and back surfaces of the insulating plate 1 are respectively provided with groove structures matching the surface structures of the first copper bar 2, the second copper bar 3, the third copper bar 4 and the fourth copper bar 5, so that the first copper bar 2, the second copper bar 3, the third copper bar 4 and the fourth copper bar 5 can be installed in the corresponding grooves. That is, the shape of the groove structure is set according to the shape of each copper bar. The first copper bar 2, the second copper bar 3, the third copper bar 4 and the fourth copper bar 5 are embedded in the front and back surfaces of the insulating plate 1 in an embedded structure. By embedding the first copper bar 2, the second copper bar 3, the third copper bar 4 and the fourth copper bar 5 in the front and back surfaces of the insulating plate 1 in a laminated embedded structure, the overall volume of the structure can be compressed to the maximum extent, which can reduce the occupied space in the server as much as possible. The groove structures on both sides (front and back) of the insulating plate 1 can be staggered with each other, which can increase the distance between the copper bars and strengthen the insulation between the copper bars.Both ends of the first copper bar 2, the second copper bar 3, the third copper bar 4 and the fourth copper bar 5 are provided with a pin structure, and the pin structure extends out of the insulating plate 1. The pins of the first copper bar 2, the second copper bar 3, the third copper bar 4 and the fourth copper bar 5 are fixed and electrically connected to the PCB by the press-in nut 8.

[0026] As shown in Figures 1 to 6 The length of the first insulating layer 6 matches the length of the middle section of the insulating plate 1, and the length of the second insulating layer 7 matches the overall length of the insulating plate 1. Two sets of fixed nuts 9 are arranged at both ends of the insulating plate 1, and grooves matching the surface structure of the fixed nuts 9 are arranged at both ends of the insulating plate 1. The fixed nuts 9 are embedded in both ends of the insulating plate 1, and the fixed nuts 9 are provided with threaded holes. The first insulating layer 6, the second insulating layer 7 and the shielding copper foil 10 are provided with through holes corresponding to the fixed nuts 9 to expose the fixed nuts 9. The left and right ends of the shielding copper foil 10 are provided with hole structures. The shielding copper foil 10 can cover at least part of the surface of the fixed nut 9 and be electrically connected to the fixed nut 9. In addition to fixing the laminated copper bar structure in the predetermined installation position of the server, the fixed nut 9 can also be electrically connected to the ground potential of the server, so that the shielding copper foil 10 is in the same potential as the ground potential of the server.

[0027] In summary, as shown in Figures 1 to 6 The laminated copper bar structure of the plastic insulation is used. First, the press-in nuts 8 installed on the left and right ends of the first copper bar 2, the second copper bar 3, the third copper bar 4 and the fourth copper bar 5 are used in combination with bolts to quickly and electrically connect and install the copper bar structure on the surface of the PCB. The fixed nuts 9 embedded in the surfaces of both ends of the insulating plate 1 are used in combination with bolts to structure the entire device structure with the shell, thereby maximizing the stability and firmness of the device structure.

[0028] The first copper bar 2, the second copper bar 3, the third copper bar 4 and the fourth copper bar 5 are respectively laminated and embedded on the front and rear surfaces of the insulating plate 1, and the structure of the first insulating layer 6 and the second insulating layer 7 is arranged to ensure the stability of the first copper bar 2, the second copper bar 3, the third copper bar 4 and the fourth copper bar 5. The shielding copper foil 10 has good electrical conductivity, thermal conductivity and corrosion resistance, and its surface is specially treated to enhance its resistance to electromagnetic interference and radio frequency interference, thereby protecting the normal operation of electronic equipment.

[0029] The embodiments of the present application are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present application to the forms disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. Embodiments were chosen and described in order to best explain the principles of the present application and its practical application, and to thereby enable others skilled in the art to best utilize the present application with various modifications as are suited to the particular use contemplated.
