Abstract
Description
Technical Field
[0001] The utility model relates to a waterproof electric wire branching device. Background Art
[0002] The structure of the wire splitter in the prior art generally includes components such as a base, a wire crimper, a piercing needle, and a sealing cover. The lower end of the base penetrates into the power bus, and the piercing needle extends up and down to pierce the surface of the power bus, so that the power bus, the piercing needle, and the branch power line can be energized. In order to achieve a waterproof effect, a sealing ring is installed between the base, the wire crimper, and the outer wall of the power bus. This belongs to peripheral waterproofing, but there is a lack of waterproof protection for the puncture point where the piercing needle pierces the power bus. It is only suitable for use in indoor environments and is relatively limited in outdoor application scenarios. Utility Model Content

[0005] Furthermore, the needle is electrically connected to the power bus and the power branch line.
[0006] Furthermore, the lower end of the power branch line is inserted into the upper end of the needle, a set screw is screwed into the side wall of the upper end of the needle, and the inner end of the set screw is pressed on the outer wall of the power branch line.
[0007] Furthermore, the middle part of the needle is screwed to the upper end of the channel by means of a threaded connection, and the lower end of the needle extends into the channel.
[0008] Furthermore, a pointed cone sealing plug is stuck between the inner wall of the upper end of the shell and the outer wall of the power branch line, and a sealing nut is screwed outward on the upper end of the shell, and the upper end of the sealing nut is pressed on the top of the pointed cone sealing plug.
[0009] Furthermore, a sealing ring is installed between the outer wall of the lower end of the wire crimper and the inner wall of the lower end of the shell.
[0010] Furthermore, the piercing needle pushes the silicone grease downward and fills up the puncture point, which means that after the piercing needle pushes the silicone grease downward, the silicone grease fills up the gap between the power bus and the piercing needle.
[0011] The application of the waterproof wire splitter provided by the utility model has the beneficial effect that when the piercing needle pierces the power bus, the piercing needle can push the silicone grease into the piercing point to fill the piercing point, thereby achieving an effective waterproof effect.

[0016] In order to more intuitively and completely understand the technical solution of the utility model, the following non-limiting feature description is now provided in conjunction with the accompanying drawings of the utility model:
[0017] like Figure 1 — Figure 3 As shown, a waterproof wire branching device includes a base 1, the middle part of the base 1 extends left and right through a power bus 2, a wire presser 3 is fixed to the upper end of the base 1 by threaded connection, the bottom of the wire presser 3 is pressed on the outer wall of the power bus 2, and a vertically penetrating channel 31 is provided in the middle of the wire presser 3, the channel 31 is located above the power bus 2, a vertically extending piercing needle 4 is screwed into the channel 31, the piercing needle 4 is located above the power bus 2, a vertically extending power branch line 5 is fixed to the upper end of the piercing needle 4, the wire presser 3 is externally screwed with a shell 6, the shell 6 covers the outside of the piercing needle 4, the lower end of the channel 31 is filled with silicone grease 7, when the piercing needle 4 moves downward, the lower end of the piercing needle 4 pierces the wire skin of the power bus 2, and the piercing needle 4 pushes the silicone grease 7 to move downward and fill the piercing point. The piercing needle 4 is electrically connected to the power bus 2 and the power branch line 5.
[0018] The lower end of the power branch line 5 is inserted into the upper end of the needle 4, and a set screw 8 is screwed into the side wall of the upper end of the needle 4, and the inner end of the set screw 8 is pressed on the outer wall of the power branch line 5. The set screw 8 can press the power branch line 5 tightly.
