[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] The insulating column provided by the embodiment of the utility model is as follows Figures 1-8 As shown, it includes: a column body 1 and a cylinder 2;

[0041] The column body 1 is an insulator, and a circular hole 11 extending along its axial direction is opened in the middle of the top surface of the column body 1, so that the cylindrical body 2 is embedded in the circular hole 11, and a plurality of limiting protrusions 13 are provided on the side where the column body 1 and the bottom surface of the cylindrical body 2 match;

[0042] The bottom surface of the cylinder 2 is provided with a plurality of limiting grooves 21, and the plurality of limiting protrusions 13 are respectively locked in the corresponding limiting grooves 21;

[0043] The bottom of the column body 1 has a fixing portion 12 for fixing the insulating column.

[0044] In the present technical solution, since the cylinder 2 is embedded in the circular hole 11, and the limiting protrusion 13 provided on the column body 1 and the limiting groove 21 provided on the bottom surface of the cylinder 2 cooperate with each other, it is avoided that during daily installation or daily use, the column body 1 and the cylinder 2 are subjected to forces, resulting in relative offset and further causing the overall failure of the insulating column; such a setting extends the service life of the insulating column.

[0045] Optimize the above technical solutions, such as Figure 6 As shown, it also includes: Bolt 3:

[0046] The top surface of the cylinder 2 is provided with a bolt hole extending along its axial direction. The bolt 3 can pass through the part to be installed 4 and the bolt hole in sequence to fix the part to be installed 4 to the cylinder 2.

[0047] In the above technical solution, the bolt 3 can pass through the part to be installed 4 (current carrier or other parts) and the bolt hole in sequence to fix the part to be installed 4 in the cylinder 2. Since the insulating column has a simple structure, it saves time and effort when installing the current carrier or other parts, and is highly efficient. It should be noted that the setting of the limiting protrusion 13 and the limiting groove 21 avoids the bolt 3 from generating a large torque during the installation process, which causes relative offset between the column body 1 and the cylinder 2.

[0048] Optimize the above technical solutions, such as Figure 3 As shown, a plurality of limiting protrusions 13 are arranged along the same radial direction of the column body 1 ; a plurality of limiting grooves 21 are arranged along the same radial direction of the cylinder 2 .

[0049] In the above technical solution, the plurality of limiting protrusions 13 and the plurality of limiting grooves 21 are arranged along the same radial direction, so that the structure of the insulating column is more stable, and relative rotation between the cylinder 2 and the column body 1 is avoided.

[0050] Optimize the above technical solutions, such as Figure 3 As shown, the plurality of limiting protrusions 13 are symmetrical and arranged around the circumference of the column body 1;

[0051] The plurality of limiting grooves 21 are symmetrical and arranged around the circumference of the cylinder 2 .

[0052] In the above technical solution, the plurality of limiting protrusions 13 and the plurality of limiting grooves 21 are arranged along the circumferential direction, so that the structure of the insulating column is more stable, and relative rotation between the cylinder 2 and the column body 1 is avoided.

[0053] Preferably, the number of the limiting grooves 21 is two, and the number of the limiting protrusions 13 is two, and the two limiting protrusions 13 are respectively clamped in the corresponding limiting grooves 21; the two limiting protrusions 13 and the two limiting grooves 21 can avoid relative rotation between the cylinder 2 and the column body 1, and the structural layout is reasonable; in addition, it should be noted that the shape of the limiting protrusion 13 is circular or square, and the shape of the limiting groove 21 is circular or square corresponding to the limiting protrusion 13.

[0054] Optimize the above technical solutions, such as Figure 2 and Figure 3 As shown, both ends of the cylindrical body 2 are provided with knurling, and the knurling is arranged in a circle around the outer circumference of the cylindrical body 2. In this arrangement, after the cylindrical body 2 is inserted into the circular hole 11, the inner circumference of the cylindrical body 2 and the cylindrical body 1 has a larger contact surface, further improving the stability of the insulating column structure. Preferably, the cylindrical body 2 is a stud.

[0055] In this technical solution, if Figure 2 and Figure 6 As shown, it also includes: a gasket 5; the gasket 5 is riveted to the top surface of the cylinder 2, and the axial direction of the cylinder 2 coincides with the axial direction of the gasket 5;

[0056] The inner diameter of the gasket 5 is greater than or equal to the diameter of the bolt 3 , and the outer diameter of the gasket 5 is greater than the diameter of the mounting through hole of the component 4 to be mounted.

[0057] In the above technical solution, it should be noted that the gasket 5 is quickly fixed to the cylinder 2 by riveting, thereby improving work efficiency; the outer diameter of the gasket 5 is larger than the diameter of the through hole of the part 4 to be installed. With this arrangement, the outer diameter of the gasket 5 is usually larger and can be adapted to the part 4 to be installed (current carrier or other parts) with a larger aperture; in addition, it should be noted that the material of the gasket 5 is steel.

[0058] It should be noted that the holes of the parts to be installed 4 (copper busbars or other parts) overlapped on the insulating column have different specifications such as large holes and small holes; when the through-hole radius of the part to be installed 4 is larger than the radius of the cylinder 2, if the cylinder 2 and the column body 1 are separated, the cylinder 2 is pulled out from the through-hole of the part to be installed 4. Through the setting of the gasket 5, since the radius of the gasket 5 is larger than the through-hole radius of the part to be installed 4, and the gasket 5 and the cylinder 2 are fixed by riveting, the axial tension of the bolt 3 can be offset (the locking force of the bolt 3 can be decomposed into radial torsion and axial tension), thereby avoiding the cylinder 2 from being pulled out of the through-hole of the part to be installed 4, so that parts to be installed 4 of different specifications (the through-hole radius on the part to be installed 4 is smaller than the radius of the gasket 5) can be installed; it should also be noted that the gasket 5 is fixed to the column body 1 by injection molding.

[0059] In this technical solution, if Figure 2 and Figure 3 As shown, the outer peripheral wall at the bottom of the column body 1 has a fixing portion 12 extending radially thereof, and the bottom surface of the fixing portion 12 is flush with the bottom surface of the column body 1. Through the setting of the fixing portion 12, the column body 1 can be better fixed, and the bottom surface of the fixing portion 12 and the bottom surface of the column body 1 are located on the same horizontal plane, making the fixing structure more stable.

[0060] Optimize the above technical solutions, such as Figure 3 As shown, there are multiple fixing parts 12, and the multiple fixing parts 12 are symmetrically arranged about the axis of the column body 1. This arrangement allows the insulating column to be better fixed; preferably, there are two fixing parts 12, and the two fixing parts 12 are symmetrically arranged about the axis of the column body 1, which ensures the stability of the fixed structure while facilitating the quick use of the insulating column.

[0061] In this technical solution, if Figure 3 and Figure 4 As shown, the fixing portion 12 is provided with a fixing through hole 14 that passes through the thickness thereof, so that the fixing member passes through the fixing through hole 14 to fix the column body 1;

[0062] And / or, a positioning column 15 is provided on the bottom surface of the fixing portion 12 to position the column body 1, and the positioning column 15 plays a role in assisting the installation of the insulating column.

[0063] In the above technical solution, the setting of the fixing through hole 14 makes the fixing structure more stable; in some embodiments, the number of the positioning columns 15 is multiple, and the multiple positioning columns 15 are arranged along the radial direction of the column body 1; in other embodiments, the fixing through hole 14 can be a metal through-hole part, and the metal through-hole part and the column body 1 form an integrated structure through an injection molding process (it can be understood that the metal through-hole part is embedded in the column body 1); preferably, the number of the positioning columns 15 is two.

[0064] The present invention further provides an electrical device, including a component to be installed 4. The electrical device also includes the above-mentioned insulating column, which fixes the component to be installed 4 on the electrical device.

[0065] Further optimize the above technical solutions, such as Figure 4-Figure 5 As shown, at least a portion of the electrical device is provided with a raised portion 6, which is provided with a connection hole 61 and a positioning hole 62. A positioning post 15 is secured within the positioning hole 62, and a fixing member can sequentially pass through the fixing through-hole 14 and the connecting hole 61 to secure the column body 1 to at least a portion of the electrical device. The fixing through-hole 14, the positioning post 15, the connecting hole 61, and the positioning hole 62 improve assembly efficiency and provide a more stable structure after assembly. The fixing member may be a bolt. At least a portion of the electrical device includes, but is not limited to, a chassis or housing, or similar parent components.

[0066] In one embodiment, the cylindrical body 2 is fixed to the column body 1 by injection molding. This arrangement further improves the stability of the insulating column, and the integrated structure can extend the service life of the insulating column. Preferably, a blind hole (i.e., a retaining groove 21) is designed at the bottom of the cylindrical body 2. During injection molding, the component opposite to it forms a reinforcing column (i.e., a retaining protrusion 13). The retaining groove 21 serves to prevent rotation and position the column.

[0067] In the above technical solution, the technical features mentioned above, the technical features to be mentioned below, and the technical features shown separately in the accompanying drawings may be combined arbitrarily, as long as the combined technical features do not conflict with each other. All feasible feature combinations are technical contents explicitly described in this document. Any of the multiple sub-features included in the same statement can be applied independently, and does not necessarily have to be applied in conjunction with other sub-features.

[0068] Key technical points or points to be protected of this utility model:

[0069] This solution satisfies the requirements of being able to overlap current carriers or other parts with large holes, and preventing the current carriers or other parts from being dragged out together with the studs when the current carriers or other parts are disassembled from the insulating column. At the same time, it satisfies the problem of using a large torque to tighten the connecting bolts, that is, the studs will not rotate loose and fail when a large torque is used. In addition, two positioning posts are designed at the bottom of the insulating column to assist in the installation of the insulating column.
