Detailed Description of the Embodiments
[0020] The following further describes the present application in detail with reference to the attached Figures 1-4 drawings.
[0021] An embodiment of the present application discloses a low-voltage insulation line tap. The tap includes a main body 1. One side of the main body 1 is used to connect the main line, and the other side is used to connect multiple branch lines. The connection between the branch lines and the main body 1 adopts the bolt pressing method. Therefore, on one side of the main body 1, there are multiple juxtaposed insertion holes 11 for the branch lines to be inserted, and on the main body 1, there are also multiple bolt pressing holes 12 communicating with the insertion holes 11. The bolt pressing holes 12 are provided with internal threads. After the branch line is inserted into the insertion hole 11, the pressing bolt 34 is screwed into the bolt pressing hole 12 and the branch line is tightened to complete the connection of the branch line.
[0022] On the other side of the main body 1, there is a clamping component for connecting the main line. The clamping component includes a base 2 and a top plate 3. The base 2 is provided with a V-shaped groove 21, and the bottom end of the V-shaped groove 21 is an arc. The top plate 3 is provided with a semi-circular groove 33. After the stripped main line is clamped into the V-shaped groove 21, the top plate 3 is buckled on the base 2. At this time, the main line is located between the V-shaped groove 21 and the semi-circular groove 33. Subsequently, the connection between the base 2 and the top plate 3 can be completed.
[0023] In the embodiment of the present application, the base 2 is provided with multiple threaded holes 24. One end of the fixing bolt 32 passes through the top plate 3 and is connected to the threaded holes 24. At the same time, in order to be applicable to main lines of different diameters, the top plate 3 is provided with a convex block 31, and the base 2 is provided with a groove 23 for the convex block 31 to be inserted. The convex block 31 is also provided with a V-shaped groove 21. Therefore, when the convex block 31 is completely inserted into the groove 23, it means that the main lines accommodated in the two V-shaped grooves 21 at this time are of the minimum size. At the same time, by changing the depth of the fixing bolt 32 screwed into the threaded hole 24, the position between the base 2 and the top plate 3 can be changed, so as to be applicable to main lines of different sizes.
[0024] Considering waterproof and anti-electric shock, protective shells 4 are provided on both the main body 1 and the base 2. The protective shells 4 are made of insulating materials. The side of the base 2 in contact with the main line does not have a protective shell 4. The protective shell 4 is provided with multiple through holes 41 for the pressing bolts to be inserted into the bolt pressing holes 12. A protective cover 5 is also connected to the protective shell 4. The protective cover 5 is buckled on the top plate 3. The protective cover 5 closes the holes on the top plate 3. The protective shell 4 is provided with mounting holes 51. The fixing bolts 32 are passed through the mounting holes 51, and the fixing bolts 32 are fixedly connected to the base 2 to connect the protective shell 4 and the protective cover 5. Finally, for waterproofing, protective caps 6 are installed in the mounting holes 51 and the through holes 41. The protective caps 6 are installed by means of threads or buckling.
[0025] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
