Figure 4 As shown, the terminal connecting wire 11 has protrusions 1111 extending towards each other on both sides of the opening of the break seam 1112; the housing, which encloses the terminal connecting wire 11 and exposes only the two ends of the terminal connecting wire 11, includes an extension tube 4, one end of the terminal connecting wire 11 is located inside the extension tube 4, each extension tube 4 has two slots 402, each slot 402 penetrates the inner wall and outer wall of the extension tube 4; wherein, the length direction of the two slots 402 of each extension tube 4 is parallel to the length direction of the break seam 1112, and the two slots 402 of each extension tube 4 are symmetrically distributed on both sides of the break seam 1112; the width of the opening of the slot 402 is greater than the distance between the two protrusions 1111 of a break seam 1112.

[0020] Terminal connection wire 11 is a copper conductor, and the housing is made of insulating plastic.

[0021] The beneficial effects of adopting the above technical solution are as follows: the slots 402 on the extension cylinder 4, which are parallel to and symmetrically distributed with respect to the break seam 1112, provide precise guidance for the external terminals. The opening width of the slots 402 is greater than the spacing of the protrusions 1111, ensuring that the external terminals slide smoothly into the break seam 1112 along the slots 402, reducing repeated adjustments and improving docking efficiency and accuracy.

[0022] In some other embodiments of the present invention, the opening of the slot 402 has a chamfered opening 403 forming a gradient opening, i.e. a flared opening. The closer to the opening of the slot 402, the wider the opening of the slot 402 becomes.

[0023] The beneficial effects of adopting the above technical solution are: the chamfer 403 at the opening of the slot 402 forms a gradient flared mouth, which reduces the accuracy requirements for alignment when inserting external terminals and further optimizes the guiding effect.

[0024] In some other embodiments of this utility model, the recessed depth of the break slit 1112 is less than the recessed depth of the groove 402, the width of the break slit 1112 gradually decreases along the recessed depth direction, and the bottom of the break slit 1112 forms an inner rounded corner.

[0025] The beneficial effects of adopting the above technical solution are: the shallow depth design of the disconnection seam 1112 forms a limiting step, the gradually decreasing width and the inner rounded corner structure disperse stress, prevent the terminal connection wire 11 from being deformed or cracked due to extrusion, and ensure the reliability of electrical connection.

[0027] The beneficial effects of adopting the above technical solution are: the slot 402 divides the inside of the extension tube 4 into two rectangular slots 401, and the gap between the terminal connecting line 11 and the inner wall of the rectangular slot 401 provides appropriate lateral elastic retraction space for the protrusion 1111 of the terminal connecting line 11 when connected to the external conductor.

[0028] like Figure 6As shown, in some other embodiments of this utility model, the terminal connecting wire 11 includes a terminal connecting wire 11 with one end being a first end 111 and the other end being a third end 113.

The number of third ends 113 is equal to the sum of the number of first ends 111 and the number of second ends 112. The end having the break slit 1112 is the first end 111, such as... Figure 5 As shown, the second end 112 has a hollow hole 1121, and the width of the terminal connecting line 11 of the third end 113 is narrowed.

[0029] Figure 6 As shown, except for the first end 111, the second end 112, and the third end 113, which is the middle section 114, the width of the middle section 114 is uniform, and the middle section 114 itself has several vertical bends.

[0030] The beneficial effect of adopting the above technical solution is that the three types of terminals correspond to three different electrical connection parts.

[0031] like Figure 1 As shown, in some other embodiments of this utility model, the shell includes a main body plate 1, and a waist-shaped shell 5 is integrally protruding from one side of the main body plate 1.

[0034] like Figure 1 , Figure 2 As shown, in some other embodiments of this utility model, the outer wall of the waist-shaped shell 5 and the main body plate 1 are integrally connected by a number of parallel ribs 7.

[0035] The beneficial effects of adopting the above technical solution are: the rib plate 7 connects the outer wall of the waist-shaped shell 5 to the main body plate 1, increases the bending strength of the waist-shaped shell 5, and prevents the terminal connection line 11 inside the waist-shaped cavity 8 from shifting due to shell deformation under force.

[0036] like Figure 3As shown, in some other embodiments of this utility model, one side of the main plate 1 and along its own edge are provided with a closed-loop groove 2, and one side of the main plate 1 is provided with a protruding tubular seat 9, and the tubular seat 9 is integrally connected with a plurality of radially diverging ribs 10.

[0037] The beneficial effects of adopting the above technical solution are: the closed-loop groove 2 facilitates the placement of the elastic sealing ring, enhancing the sealing performance of the edge of the main body plate 1. The tubular seat 9, in conjunction with the radial rib 10, provides auxiliary installation positioning points, and the rib 10 simultaneously strengthens the structural stability of the tubular seat 9, thereby enhancing the structural strength of the entire main body plate 1.

[0038] like Figure 2 , Figure 3 As shown, in some other embodiments of this utility model, the edge of the main plate 1 is provided with a lug 12, the lug 12 is provided with a through hole 3, and the lug 12 is located on the periphery of the closed-loop groove 2.

[0039] The advantages of adopting the above technical solution are: the lug 12 and the through hole 3 facilitate the overall fixed installation of the end shell; the lug 12 is located outside the closed-loop groove 2, avoiding interference of the mounting parts with the sealing area. The external bolts can easily enter the lug 12 and achieve assembly.
