Description

Technical Field

[0001] The utility model relates to the technical field of electrical boards, in particular to an insulating support structure for an electrical board. Background Art

[0002] In the existing design, referring to Figure 1 , for pack boxes with different required sizes, corresponding electrical boards need to be designed accordingly. The positions of electrical components such as shunt resistors, fuses, relays, fuse tubes, low-voltage contactors, and BMS boards are designed and laid out according to the size of the box, resulting in a wide variety of electrical board bodies and a high design repetition rate. Due to the large number of types of electrical board bodies, the errors and risks in design and processing are relatively increased, the assembly efficiency is low, a large amount of time and repair costs are wasted. When electrical components with electrical relationships are connected by copper bars, insulating columns are required as support members between the electrical board bodies. Since the heights of the power connection parts between the electrical components are different, it is necessary to adjust the support height of the insulating columns through pads or elevation brackets, resulting in the need to design pads and elevation brackets with different heights according to requirements, which not only has a large assembly difficulty but also a low design efficiency.

The insulating columns and the intermediate insulators are detachably assembled, and the distance between the two can be adjusted along the axial direction of the insulating columns.

[0006] One end of the insulating column has a stepped threaded hole, and the other end has a threaded through hole. The stepped threaded hole sequentially includes a first threaded hole and a second threaded hole from the outside to the inside. The aperture of the first threaded hole is larger than that of the second threaded hole, and the aperture of the threaded through hole is the same as that of the second threaded hole.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0018] Refer to Figure 2-5, an insulating support structure for an electrical board, comprising an electrical board body 1, on which a number of electrical components are installed, and the electrical components with electrical connections are electrically connected by copper bars. A number of reserved holes 2 are provided on the electrical board body 1, and some of the electrical components and some of the copper bars are supported at the positions of the reserved holes 2 of the electrical board body 1 by insulating columns 7; and / or some of the electrical components and some of the copper bars are supported at the positions of the reserved holes 2 of the electrical board body 1 by insulating columns 7 and an intermediate insulator 11. The insulating column 7 and the intermediate insulator 11 are detachably assembled, and the distance between the two can be adjusted along the axial direction of the insulating column 7.

[0019] In this device, a number of reserved holes 2 are provided on the electrical board body 1, and the electrical components are installed at appropriate positions of the reserved holes 2 as required, realizing the generalization of the electrical board body 1 and meeting the selection and installation of different accessories. In this device, a certain number of electrical components and some copper bars with a lower installation height are installed through the insulating columns 7, and then different support heights are adjusted through the combination of the insulating columns 7 and the intermediate insulator 11. In this way, the insulating columns 7 and the intermediate insulator 11 can be mass-produced, and during assembly, only the distance between the insulating column 7 and the intermediate insulator 11 needs to be adjusted to achieve different installation heights, without the need to additionally design structures such as cushion blocks and elevation brackets, with a wide range of applications, reduced design difficulty, and improved production efficiency.

[0020] One end of the insulating column 7 has a stepped threaded hole 4, and the other end has a threaded through hole 3. The stepped threaded hole 4 sequentially includes a first threaded hole 5 and a second threaded hole 6 from the outside to the inside. The aperture of the first threaded hole 5 is larger than that of the second threaded hole 6, and the aperture of the threaded through hole 3 is the same as that of the second threaded hole 6. The end of the insulating column of this device for installing electrical components or copper bars is provided with a stepped threaded hole 4, so that electrical components with different installation apertures can be accommodated. For those with a small aperture, small studs are threadedly connected to the second threaded hole 6, and for those with a large aperture, large studs are threadedly connected to the first threaded hole 5, with better flexibility. Finally, for one forming method of the insulating column, nuts corresponding to the three sizes of the first threaded hole 5, the second threaded hole 6, and the threaded through hole 3 are first placed in the mold, and then insulating glue is poured in.

[0021] Reference Figure 4 , on the outer circumference of the end of the insulating column 7 provided with the threaded through hole 3, there is a first external thread 8. One end of the intermediate insulator 11 has a cylindrical cavity 10, and on the circumferential wall of the cylindrical cavity 10 of the intermediate insulator 11, there is an internal thread 9. The first external thread 8 and the internal thread 9 can be threadedly engaged to threadedly connect the insulating column 7 and the intermediate insulator 11, and by rotating forward or backward, the total support height of the insulating column 7 and the intermediate insulator 11 can be changed.

[0022] Reference Figure 4, one end of the intermediate insulator 11 away from the cylindrical cavity 10 has a protruding head 12, the protruding head 12 has a second external thread 13, and the protruding head 12 can penetrate through the reserved hole 2 and be locked with the electrical plate body 1 through a nut, so that the intermediate insulator 11 can be directly fixed on the electrical plate body 1.

[0023] Reference Figure 5 , the second external thread 13 can be threadedly engaged with the second threaded hole 6, so that the insulating column 7 and the intermediate insulator 11 can be wirelessly stacked within a reasonable length range, which can meet the use requirements of different support heights.
