Description

Technical Field

[0001] The utility model relates to the field of wall bushings, and particularly to an insulating bushing with terminal posts for wall penetration. Background Art

[0002] An insulating bushing is an insulating protective sleeve used for the external protection of wires, cables, electronic components, optical fibers, pipes, and equipment, etc. Its main function is to prevent external factors, such as ultraviolet rays, moisture, aging, mildew, or fire, etc., from damaging the internal conductors or equipment. The selection of insulating bushings needs to consider the installation environment, usage conditions, and performance requirements, and select appropriate materials according to the actual situation. The specific types of insulating bushings are also very rich, such as fiberglass insulating bushings, PVC bushings, heat shrinkable bushings, Teflon bushings, and ceramic bushings, etc. Each type of bushing has its unique performance and applicable scenarios. For example, as a fiberglass insulating bushing, the yellow wax tube has good flexibility, elasticity, dielectric property, and chemical resistance, and is especially suitable for wiring insulation and mechanical protection of devices such as motors, electrical appliances, instruments, and radios.

[0003] A high-voltage wall bushing with convenient installation, with the public number CN220086941U, includes a wall body, a mounting plate, a first porcelain part, and a second porcelain part. Metal accessories are provided at the ends of the first porcelain part and the second porcelain part. A plurality of connection holes are opened on both of the two metal accessories. A first round opening is opened on the wall body. The mounting plate is installed in the first round opening. A second round opening is opened on the mounting plate. One end of the first porcelain part and the second porcelain part is connected in the second round opening. Sealing plates are fixedly provided on both the first porcelain part and the second porcelain part. The two sealing plates respectively abut against both sides of the mounting plate. Pouring holes communicating with the second round opening are opened on both sides of the mounting plate. By docking one end of the first porcelain part and the second porcelain part in the second round opening, heating the hot melt adhesive on the two sealing plates to make the two sealing plates adhere to both sides of the mounting plate, and then injecting concrete into the two pouring holes for fixation, the installation is very convenient. In this solution, the replacement and use of the wall bushing are relatively cumbersome. For this reason, we propose an insulating bushing with terminal posts for wall penetration.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-3 , a terminal-post-through-wall insulating bushing, including a connecting plate 1. The upper end of the connecting plate 1 is installed with an upper bushing 2, the lower end of the connecting plate 1 is installed with a lower bushing 3, and a connecting column 4 is provided in the middle of the upper bushing 2, and the connecting column 4 penetrates the connecting plate 1. It also includes: a clamping block. The connecting plate 1 is divided into a left half 11 and a right half 12. An L-shaped block 7 is provided at the right end of the lower part of the left half 11, and a notch 8 is provided at the corresponding position of the right half 12 relative to the L-shaped block 7, and a hole 9 is provided on the surface of the connecting plate 1; a structure for assisting the position of the connecting plate 1, which at least includes a set of misaligned clamping structures. The basic composition of the insulating bushing is fixed by installing L-shaped blocks 7 on both sides of the connecting plate 1.

[0026] Further, the left end of the connecting plate 1 is the left half 11, the right end of the connecting plate 1 is the right half 12, and the two sides of the connecting plate 1 are clamped and fixed to each other.

[0027] Furthermore, there are two sets of offset snap - connection structures. One set is installed at the right - hand lower part of the left half - face 11, and the other set is installed at the left - hand upper part of the right half - face 12. One set fixes the upper part of the connecting plate 1, and the other set fixes the lower part of the connecting plate 1.

[0028] Furthermore, the offset snap - connection structure includes a left half - face 11, a right half - face 12, an L - shaped block 7, a notch 8 and a hole 9. The L - shaped block 7 is installed at the right end of the left half - face 11, and a notch 8 is provided at the position of the right half - face 12 corresponding to the L - shaped block 7. A hole 9 is arranged inside the notch 8. The offset snap - connection structure is formed by fixing the top of the L - shaped block 7 inside the notch 8, thereby fixing the connecting plate 1.

[0029] Furthermore, the inside of the notch 8 is larger than the L - shaped block 7, and a hole 9 is arranged at the part near the center inside the notch 8. A fixing pin 10 is installed inside the hole 9. The inside of the notch 8 is larger than the L - shaped block 7, and the surface of the notch 8 is the same as that of the L - shaped block 7. After the L - shaped block 7 enters the inside of the notch 8, move one side of the connecting plate 1. The top of the L - shaped plate 7 is snap - connected with the inside of the notch 8. The hole 9 is arranged inside the notch 8. Insert the fixing pin 10 into the hole, and the fixing pin 10 restricts the range of the L - shaped block 7 to prevent the L - shaped block 7 from slipping, thereby the L - shaped block 7 fixes the connecting plate 1.

[0030] Furthermore, limit blocks 5 are provided at both ends of the side of the upper sleeve 2 and the lower sleeve 3 close to the connecting plate 1. The limit blocks 5 fix the upper sleeve 2 and the lower sleeve 3 inside the connecting plate 1. By moving the limit blocks 5 inside the empty slots 6, the limit blocks 5 are fixed, and further the upper sleeve 2 and the lower sleeve 3 are fixed.

[0031] Furthermore, empty slots 6 are provided on the surfaces of the left half - face 11 and the right half - face 12. The entrances of the empty slots 6 are enlarged, and the internal trajectories are reduced. When the limit blocks 5 enter the inside of the empty slots 6, the limit blocks 5 move along the trajectories of the empty slots 6, and the empty slots 6 fix the limit blocks 5. When disassembling, rotate and move the limit blocks 5 along the same trajectories to the exits of the empty slots 6.

[0032] Working principle: Open the connecting plate 1, place the upper sleeve 2 and the lower sleeve 3 inside the connecting plate 1, align the L-shaped blocks 7 on the right half 2 and the left half 11 with the notches 8, insert the L-shaped blocks 7 into the notches 8, insert the limiting blocks 5 at the lower ends of the upper sleeve 2 and the lower sleeve 3 into the empty slots 6, rotate the upper sleeve 2 and the lower sleeve 3, and the limiting blocks 5 move along the trajectory of the empty slots 6. The limiting blocks 5 move into the interior of the empty slots 6 to fix the upper sleeve 2 and the lower sleeve 3. After the L-shaped blocks 7 are inserted into the notches 8, move the right half 12 upward to align the left half 11 and the right half 12. The upward movement of the right half 12 drives the L-shaped blocks 7 in the upper part and the notches 8 in the lower part to rise, and the holes 9 are exposed inside the notches 8. Insert the fixing pins 10 into the holes 9 to fix the left half 11 and the right half 12. When removal is required, perform the same steps, take out the fixing pins 10, rotate the upper sleeve 2 and the lower sleeve 3, move the limiting blocks 5 to the exits of the empty slots 6 and take them out, and move one side of the connecting plate 1 in the opposite direction to remove it.
