[0020] As shown in FIG. 1 to FIG. 8, a waterproof device for connecting branch wire with main wire provided by the present invention includes a housing component 11 and a puncture locking screw component 12 matched with the housing component 11, wherein the housing component 11 includes a housing 111, a pair inner threads 111A is located at the middle of opening slot, one side of the housing 111 is provided with an opening slot for placing the main wire 20 and a positioning step for main wire 111B for positioning the main wire 20; a branch wire hole 111F is also formed on the housing 111 for inserting and installing the branch wire 30; the puncture locking screw component 12 includes a metal spike 122, and when the puncture locking screw component 12 is screwed into a pair inner threads 111A, the metal spike 122 pierces into the cores of the main wire 20 and the branch wire 30 to realize the conduction of electricity.

[0021] As a preferred example of the present invention, as shown in FIG. 3, the housing component 11 further includes a first insulation sealant 112, which is prefilled in the branch wire hole 111F to seal the branch wire 30 inserted into the hole. The insulation sealant can be silicone grease, which is waterproof and corrosion-proof. In this example, silicone grease sealant is preferably used, and in other examples, sealants made of other polymer materials can also be used.

[0022] Specifically, as shown in FIG. 5-2, one surface of the housing 111 is provided with an opening slot, the middle section of the opening slot is provided with a pair of inner threads 111A; the bottom of the middle section of the opening slot is provided with a through hole 111D, which is used to connect the branch wire hole 111F extending from the side; the bottom of the rear section of the branch wire hole 111F is provided with a V-type positioning step for branch wire 111E, and the bottom of the opening slot is provided with two V-type main wire positioning steps 111B, which are located on two sides of the puncture position respectively; and blocking water step 111C are also arranged at the two ends of the opening slot.

[0023] As shown in FIG. 5-1, the puncture locking screw component 12 is composed of a hexagon screw; 121, a metal spike 122, a second insulation sealant 123 and a cover plate 124. The head of the hexagon screw 121 is provided with a top cavity 121A, and the bottom of the cavity is provided with a plurality of small holes 121B. The center of the bottom of the hexagon screw 121 is provided with a hexagonal bottom cavity 121C for installing the metal spike 122. The top cavity 121A is prefilled with a sufficient amount of the second insulation sealant 123 and covered with the cover plate 124.

[0024] In this example, the puncture locking screw component 12 is preferably configured as a hexagon screw 121. In other examples, the puncture locking screw component 12 can also be composed of a T-shaped screw or a butterfly screw; which can be configured by users according to actual use requirements.

[0025] More specifically, as shown in FIG. 1, the top cavity 121A of the hexagon screw 121 is filled with the second insulation sealant 123. When the puncture locking screw component 12 is screwed into a pair inner threads 111A of opening slot, the main wire 20 can be pushed to the bottom of the opening slot firstly. The locking operation should be stopped when it's screwed into 23 teeth, as the left station shown in FIG. 2, a screwdriver or other suitable rods can be used to quickly push the cover plate 124 to press the second insulation sealant 123 to flow evenly around the main wire 20 through the six small holes 121B. Then the puncture locking screw component 12 need to be continually screwed in until it locks the main wire 20 tightly.

[0026] As shown in FIG. 3, the cover plate 124 is pushed to the bottom of the top cavity 121A. During this process, the second insulation sealant 123 flows around the main wire 20 through the six small holes 121B evenly, and the redundant second insulation sealant 123 overflows to the openings on both sides of the hexagon screw 121.

[0027] When the connections of double stations are completed, as shown in FIG. 4, the metal spike 122 of the puncture locking screw component 12 penetrates the main wire 20 and the branch wire 30 to make their conductors connected. Around the pierced hole, the main wire 20 is pressed by the bottom of the hexagon screw 121 and sealed by the second insulation sealant 123 in all directions, thus it has good sealing performance.

[0028] As shown in FIG. 5-1 and FIG. 5-2, when the second insulation sealant 123 is prefilled in top cavity 121A, all the small holes 121B can be filled with the extra second insulation sealant 123 when the cover plate 124 is assembled, so the prefilled volume of the second insulation sealant 123 should be controlled to ensure no overflowing from any small hole 121B.

[0029] As a preferred example of the present invention, the positioning step for main wire 111B can reduce the swinging of the main wire 20 during the process of puncturing, and the blocking water step 111C can reduce rainwater flowing to the center of the waterproof device 10 when it is installed with the opening slots facing ground. The through hole 111D is arranged for the metal spike 122 to go through and can be used as a nozzle to fill in the first insulation sealant 112. Considering that the first insulation sealant 112 may overflow into the opening slot of the housing 111 during the insertion of a thicker branch wire 30, the through hole 111D is preferably configured as a thin-bottomed stepped hole, and the bottom thickness of the stepped hole can be controlled to be 0.2-0.3 mm, and the diameter is about 1 mm. In other examples, the bottom thickness and diameter of the stepped hole may have other values.

[0030] In this example, the positioning step of branch wire 111E is preferentially arranged in the rear half of the branch wire hole 111F, so that the branch wire 30 can be always centrally positioned. As the branch wire hole 111F is too deep, a small amount of air may be sealed at the bottom of the branch wire hole 111F when the first insulation sealant 112 is filled in, but it doesn't affect the performance of waterproof and insulation.

[0031] As shown in FIG. 6, a pair inner threads 111A is composed of a left part of inner threads and a right part of inner threads with each part counts about of the full inner threads, and the positioning step of main wire 111B and the positioning step of branch wire 111E are configured for centering the main wire 20 and the branch wire 30 respectively.

[0032] As shown in FIG. 7, the six small holes 121B are evenly located at the outer side of the six sides of the bottom cavity 121C, so that the second insulation sealant 123 can flow around the main wire 20 much evenly when the cover plate 124 is pushed.

[0033] FIG. 8 is an outdoor installation diagram of the waterproof device 10 provided by the present invention. During the installation, the side of the opening slot of the housing 111 is installed downward, which can significantly improve the sealing performance and service life of the waterproof device 10 for outdoor application. It should be pointed out that, in order to facilitate the display, FIGS. 1 to 6 adopt a drawing mode in which the side of the opening slot of housing 111 is arranged upward.

[0034] In specific use, in order to facilitate the understanding of the present invention, it is described with the attached drawings;

[0035] The waterproof device 10 is used for the connection of strand wires, and its operation methods are as follows: [0036] 1, screw off the two puncture locking screw components 12 from the housing component 11; [0037] 2, use one puncture locking screw component 12 to puncture a small hole on each main wire 20 for easy positioning with the main wire 20 upon the platform of the housing 111; [0038] 3, put one main wire 20 into one opening slot of the housing 111; [0039] 4, use one puncture locking screw component 12 to position the small hole formed on the main wire 20, and then screw into 23 teeth; [0040] 5, push the cover plate 124 to press the second insulation sealant 123 onto the main wire 20 by a suitable rod; [0041] 6, insert the related branch wire 30 into the branch wire hole 111F to the end; [0042] 7, continue to screw the puncture locking screw component 12 to lock the main wire 20 tightly to finish the connection of the main wire 20 and the branch wire 30; [0043] 8, repeat the above operations from 3 to 7 to finish the connection of another main wire 20 and branch wire 30.

[0044] The waterproof device provided by the present invention has a compact structure, doesn't need to peel the jackets of main wire and branch wire, the operation is quite quick with good waterproof and insulation performance of the splice connected, and it can only be used for the connection of strand wires.
