[0024] As Figures 1 to 3 shown, the present utility model provides a twelve-core cable joint with high safety factor, including a protective shell 1. At the center position of the front end of the protective shell 1, there is a connecting protective shell 2. Inside the connecting protective shell 2, a cable joint 3 is connected in a limited way. Inside the cable joint 3, twelve interfaces 31 are evenly penetrated, and limit posts 4 are symmetrically arranged on the upper and lower sides of the cable joint 3;

[0025] The protective shell 1 includes an upper shell 11 and a lower shell 12. At the four vertex positions of the upper shell 11, connecting holes 111 are provided, and connecting nuts 112 are provided in the connecting holes 111. At the four vertexes on the inner side of the lower shell 12, connecting platforms 121 are provided, and threaded columns 122 are fixedly connected to the upper ends of the connecting platforms 121. The threaded columns 122 are threadedly connected to the connecting nuts 112.

Insulating sheets 15 are provided in the circular heat dissipation holes 14. The cable placement opening 13 is convenient for inserting a cable to place the cable. The insulating sheets 15 are placed in the circular heat dissipation holes 14. The thickness of the insulating sheet 15 is thinner than that of the protective shell 1, which is more convenient for heat dissipation and has good dust and water protection effects.

[0027] Further, the upper shell 11 and the lower shell 12 are arched protrusions at the central position and have a rectangular overall structure. The upper shell 11 and the lower shell 12 are plastic shells. The upper shell 11 and the lower shell 12 are connected in an upper and lower matching manner. The shapes of the upper shell 11 and the lower shell 12 are for better placement and installation of cables, adapting to the arc of the cables. Plastic has the effects of insulation, corrosion prevention, and high safety factor. The upper shell 11 and the lower shell 12 are convenient to connect and have strong practicability.

[0028] Further, a spring is provided inside the limit post 4, and the lower end of the limit post 4 is a fixed post, while the upper end of the fixed post is a movable post. The limit post 4 is a movable button that moves along the connecting protective shell 2 until it is properly fitted. The limit post 4 is inserted into the position of the connecting hole on the connecting protective shell 2, thereby realizing the installation of the cable connector 3.

[0029] Further, raised blocks 21 are provided on the outer surface of the connecting protective shell 2. The raised blocks 21 are evenly distributed on three sides of the connecting protective shell 2, and limit grooves 22 are provided on the rear sides of the raised blocks 21.

[0030] Furthermore, shock-absorbing rubber columns 123 are provided at the central position inside the lower shell 12. The shock-absorbing rubber columns 123 are arranged at the rear end of the connecting protective shell 2. The function of the shock-absorbing rubber columns 123 is to facilitate the placement of the cable in the protective shell 1, prevent the connection stability between the cable and the twelve interfaces 31 from deteriorating due to the vibration of the cable, and ensure a longer service life.

[0031] Working process: First, place the cable inside the lower shell 12, then connect the cable to the twelve interfaces 31. The cable connector is preferably inserted into the connecting protective shell 2, and the limit post is engaged in a limiting manner with the connecting hole on the connecting protective shell 2, so that the cable can be accurately connected to the twelve interfaces 31. Then, pass the connecting nut 112 through the upper shell 11, and the connecting nut 112 is threadedly connected to the threaded post 122, so that the upper shell 11 and the lower shell 12 are connected in a matching and sealed manner. The entire connector structure has good waterproof and dustproof effects, is simple to install, has good shock-absorbing effects, and good stability.
