The insulating inner core is placed in the insulating inner core holding cavity, and an annular channel is provided at the triangular apex of the upper and lower extension pieces, and the annular channel is used for the insertion of vertically intersecting transmission lines; the insulating inner core has a triangular appearance, and it adopts soft insulation It is made of high-quality materials, and the power line is wrapped by an insulating inner core after resting on it to provide good insulation;

The outer seal is used to seal the gap on the shell, including a strip-shaped edge and circular plugs arranged at both ends of the strip-shaped edge. The strip-shaped edge is used to seal the gap between the upper and lower extension pieces of the shell. The circular plug The head is used to block the openings at both ends of the base part.

The outer sealing strip is fixed on the casing by bonding.

The present invention has following technical effect:

1. It adopts triple insulation of insulating shell, insulating inner core and insulating edge banding, which has good insulating performance and basically eliminates the leakage site at the junction of transmission lines;

2. It is easy to install, just wrap the insulating device on the junction of the transmission line, and then install the insulating edge banding.

Description of drawings

Specific embodiments of the present invention will be described in further detail below in conjunction with accompanying drawing, wherein:

Fig. 1 is the overall structure schematic diagram of embodiment 1 of the present invention;

Fig. 2 is the horizontal sectional view of embodiment 1 of the present invention;

detailed description

Example 1

As shown in Figure 1-2, the transmission lines 1a, 1b and the transmission line 2 intersect vertically. The vertical intersection mode is that the end of the transmission line 1a is spirally wound on the 2, and the transmission line 1b is connected with the spiral winding part 3b. Three transmission lines The outside where the lines intersect is wrapped with a transmission line insulation device. The transmission line insulation device includes a shell 10, an insulating inner core 20 and an outer seal 30; the shell 10 includes a base part 11 and an extension part 12, and the base part 11 is a circle with a side opening 16a cylinder, the center of the cylinder is the inner cavity 16 of the base part, and the inner cavity 16 of the base part is used to accommodate the power line 1a and the power line 2 connected oppositely. The upper and lower edges of the side opening 16a are connected, and the upper and lower extension sheets have triangular inner recesses respectively. The inner recesses of the upper and lower extension sheets are combined to form a triangular inner cavity 15 of the extension sheet. The cavities 16 together form the insulating inner core accommodation cavity, the insulating inner core 20 is placed in the insulating inner core accommodation cavity, and the triangular apex of the upper and lower extension pieces is provided with an annular channel 17, and the annular channel 17 is used for the extension of the vertically intersecting transmission line 1b. enter;

The insulating inner core 20 is placed in the insulating inner core accommodating cavity, which is made of soft insulating material, and the power line can be sunk into it if the power line rests on it, so that the insulating core can wrap the power line to provide good insulation.

The outer sealing strip 30 includes a strip-shaped edge seal 30a and circular plugs 30b arranged at both ends of the strip-shaped edge seal 30a. The strip-shaped edge seal 30a is used to seal the gap between the upper and lower stretching pieces, and the circular plug 30b is used for Openings at both ends of the base portion 11 are blocked.

During installation, after the transmission line is connected, open the upper and lower extension pieces of the transmission line insulation device, insert the transmission line into the insulation device, then put the insulating inner core, and finally seal it with an outer seal. The way of bonding.

Those skilled in the art will recognize that without departing from the protection scope of the present invention, various modifications, changes and combinations can be made to the above-mentioned embodiments, and it is believed that such modifications, changes and combinations are within the scope of original ideas. within the scope.
