[0030] See also Figure 1 , Figure 2Preferably, the first shell 3 and the second shell 4 are provided with a buckle structure at one end away from the rotating shaft 6. The buckle structure comprises a buckle head 51 and a buckle groove 52 adapted to the buckle head 51, and the buckle head 51 and the buckle groove 52 are provided on the first shell 3 and the second shell 4 respectively.

[0031] Preferably, the first shell 3 and the second shell 4 are respectively configured as a square shell and an "L"-shaped hook shell that is snap-connected, and the "L"-shaped hook shell includes a long handle portion 41 and a short handle portion 42, one end of the long handle portion 41 is rotatably connected to one end of the square shell, and the short handle portion 42 is provided with the buckle head 51 or the buckle groove 52 on the side wall close to one end of the long handle portion 41, and the square shell is provided with an adaptive buckle groove 52 or the buckle head 51 on the side wall close to the short handle portion 42.

[0032] See also Figure 2 , Figure 4 as well as Figure 6 Specifically, in the present application, the first shell 3 is a square-shaped shell, and the second shell 4 is an "L"-shaped hook shell. It should be noted that the first shell 3 includes a first shell body 35 and an extension plate 36 arranged at the end of the first shell body 35 in the length direction and extending away from the end of the first shell body 35. The two extension plates 36 are respectively provided with rotation holes 37 at one end of each side. The end of the long handle 41 of the second shell 4 away from the short handle 42 is provided with a through hole 43. The rotating shaft 6 passes through the through hole 43 and extends out of the through hole 43 at both ends. The rotating shaft 6 extending out of the through hole 43 is inserted into the two rotation holes 37, thereby realizing the rotatable connection between the first shell 3 and the second shell 4.

[0033] See also Figure 3 In the present application, a relative notch 38 is provided on one side of the two extension plates 36 close to the rotating hole 37, and the two notches 38 and a recessed groove 39 recessed on a side opposite to a side of the first shell body 35 close to the extension plate 36 and perpendicular to the extension plate 36 constitute the recess 31.

[0034] See also Figure 6 Preferably, the end section of the short handle 42 of the second shell 4 is set as an arc-shaped notch 33, and the arc-shaped notch 33 is formed from a side close to the long handle 41 to a side away from the long handle 41, and the cross section of the arc-shaped notch is similar to a trapezoidal structure or a triangular structure. When the first shell 3 and the second shell 4 need to be opened, the user only needs to press the position of the arc-shaped notch 33, and the connection between the first shell 3 and the second shell 4 can be disconnected by force, so that the first shell 3 and the second shell 4 can be opened.

[0035] It is also possible that the buckle groove and the buckle head are respectively arranged on the opposite surfaces when the first shell 3 and the second shell 4 are buckled. During installation, the user only needs to press the first shell 3 and the second shell 4 to buckle the buckle head into the buckle groove, and the first shell 3 and the second shell 4 are fastened and connected. When the above-mentioned buckle groove and buckle head are opposite to each other, the first shell 3 can be set as a square-like structure, and the second shell 4 can also be set as a square sheet structure.

[0036] See also Figure 2 Preferably, a plurality of first partition bars 310 are arranged in the groove 31 of the first shell 3, and a second partition bar 44 is arranged at a position corresponding to the first partition bar 310 on the second shell 4. The arrangement of the first partition bar 310 and the second partition bar 44 further isolates and fixes each main wire 2, improves the insulation performance of the entire connection device, and reduces the risk of short circuit. At the same time, the arrangement of the first partition bar 310 and the second partition bar 44 also makes the main wire 2 more stable when installed in the groove 31, and is not easy to move or twist, thereby ensuring the stability of the electrical connection.

Figure 1 When there is one strip, two piercing pieces 32 are provided, and the two piercing pieces 32 are provided on both sides of the first partition strip 310, respectively, to achieve the connection between the two main lines and the branch line 1. Figure 7 When three strips are set, four piercing pieces 32 are correspondingly set. The four piercing pieces 32 are respectively arranged between the first partition strips 310 and on the side of the edge of the first partition strip 310 away from the adjacent first partition strip 310, so as to realize the connection between the four main lines and the branch line 1.

[0038] See also Figure 2 as well as Figure 5 Preferably, the end of the piercing piece 32 away from the sharp thorn is arranged on a PCB board 7, and the PCB board 7 is connected to the branch line 1. In this embodiment, the PCB board 7 is arranged at the bottom of the groove 31 of the first shell 3, and the branch line 1 is arranged in the first shell 3 and extends from the end of the first shell 3 away from the rotating shaft 6.

[0039] See also Figure 5Preferably, the sharp thorn head is set to a "V" shape. The setting of the V-shaped structure enables the sharp thorn head to have stronger penetration and cutting ability when piercing the insulation layer of the main wire 2, thereby improving the reliability of the connection. At the same time, the sharp thorn head with a V-shaped structure can better adapt to different diameters of the main wire 2, reduce damage to the inside of the main wire 2 during the piercing process, and improve the safety of the connection.

[0040] The utility model provides a main line branch connector. When in use, the main wire 2 is placed in the groove 31 of the first shell 3, and then the first shell 3 and the second shell 4 are pressed away from the end of the rotational connection so that the buckle head 51 is buckled in the buckle groove 52, and the first shell 3 and the second shell 4 are buckled. Due to the buckling of the first shell 3 and the second shell 4, the main wire 2 is squeezed, and the insulation layer of the main wire 2 is pierced by the piercing piece 32 on the first shell 3. After piercing the insulation layer, the piercing piece 32 is stuck between the wires of the main wire, thereby completing the connection between the main wire 2 and the branch line 1.

[0041] Therefore, the main line branch connector can realize the quick connection between the main line 2 and the branch line 1 by a simple pressing action, and the connection is firm and not easy to come out, which greatly improves the work efficiency and reduces the complexity and error of manual operation. At the same time, the main line branch connector can be installed at any position of the main line 2, which is convenient for the installer to select a suitable position for installation. At the same time, the main line 2 is arranged between the first shell 3 and the second shell 4, which can be less exposed to the air and has a better sealed and waterproof effect.

[0042] Embodiment 2:

[0043] This embodiment 2 is substantially the same as embodiment 1, except that a plurality of mutually insulated piercing pieces are provided on the second shell, and the piercing pieces are provided at positions corresponding to the grooves of the first shell. When in use, the main wire is placed in the groove of the first shell, and then the first shell and the second shell are pressed away from the end of the rotational connection, so that the buckle head is buckled in the buckle groove. At this time, the piercing pieces on the second shell pierce the insulation layer of the main wire provided in the groove of the first shell due to the pressure between the first shell and the second shell, thereby completing the connection between the main wire and the branch wire.

[0044] The above disclosures are only several preferred embodiments of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
