[0026] The present application is further described in detail below with reference to the accompanying drawings.

[0027] The embodiment of the present application provides a cable junction box with high installation efficiency. Figure 1 -Attached Figure 4 , including an upper box body 10 and a lower box body 20 with openings at both ends. When the upper box body 10 and the lower box body 20 are spliced ​​together, a cable junction box is formed. For the convenience of description, in the assembled state, the position where the lower box body 20 is located is defined as the bottom, and the position where the upper box body 10 is located is defined as the top;

[0028] The upper box body 10 and the lower box body 20 both have cavities inside. The cavities penetrate through one side of the upper box body 10 and the lower box body 20 to form windows. In the assembled state, the upper box body 10 and the lower box body 20 are closely attached to each other on the side with the windows to form a junction box.

[0029] The openings at both ends of the lower box body 20 are equipped with wiring barrels 30 for passing and fixing cables. Two lower packaging bodies 21 are fixedly connected to the middle of the cavity of the lower box body 20. A groove is defined on the side of the lower packaging body 21 away from the lower box body 20, that is, the groove is located at the top of the lower packaging body 21. In the assembled state, one side of the cable fits into the inner side of the groove. The connection point of the two cables is located between the two lower packaging bodies 21. The sides of the two lower packaging bodies 21 away from each other serve as the contact surface.

[0030] Two upper packaging bodies 11 are fixedly connected to the middle of the upper box body 10. A groove is defined on the side of the upper packaging body 11 away from the upper box body 10. That is, the groove of the upper packaging body 11 is located at the bottom of the upper packaging body 11. The side where the two upper packaging bodies 11 are close to each other is the contact surface. An elastic sealing member 12 is provided on the contact surface of the upper packaging body 11.

[0031] In the assembled state, the upper box body 10 and the lower box body 20 are tightly attached on one side with the window to form a junction box, and the wiring barrel 30 installed on the lower box body 20 is looped around the outside of the cable, that is, the cable is installed on the lower box body 20, and the two lower encapsulation bodies 21 are located between the two upper encapsulation bodies 11. The contact surface of the sealing member 12 and the lower encapsulation body 21 is tightly attached, and the upper box body 10 is relatively fixed with the lower box body 20 through the friction connection between the sealing member 12 and the lower encapsulation body 21.

[0032] The following is a further introduction based on specific usage scenarios.

[0033] During use, the operator passes the two cables to be connected through the wiring barrels 30 set at both ends of the lower box body 20 respectively, and then continues to pull the two cables to complete the connection between the two lower packaging bodies 21 of the lower box body 20, forming a cable connection point. At this time, the two cables are respectively fixed by the two wiring barrels 30. It can also be understood that the lower box body 20 is fixed on the two cables through the two wiring barrels 30, and the two cables are in contact with the inner side of the groove of the lower packaging body 21 after passing through the wiring barrels 30.

[0034] After the operator completes the connection of the two cables, the junction box can be sealed. The operator aligns the window of the upper box body 10 with the window of the lower box body 20, and makes the end faces of the upper box body 10 and the lower box body 20 where the windows are located close together. In this state, the two upper encapsulation bodies 11 inside the upper box body 10 are inserted into the cavity of the lower box body 20, and the two lower encapsulation bodies 21 of the lower box body 20 are located between the two upper encapsulation bodies 11, and the seal 12 on the upper encapsulation body 11 is pressed and close to the contact surface of the lower encapsulation body 21, thereby realizing the installation of the cable junction box. At this time, the cable is located on the inner side of the groove of the upper encapsulation body 11 and the lower encapsulation body 21. The upper encapsulation body 11 and the lower encapsulation body 21 enclose the cable connection in a closed space, and the operator can fill the aforementioned closed space with a protective medium.

[0035] During actual use, the lower box body 20 is at the bottom of the cable, and the upper box body 10 is at the top of the cable. The lower box body 20 bears the overall stress of the junction box. The upper box body 10 and the lower box body 20 are relatively fixed in position through the friction connection between the upper packaging body 11, the seal 12 and the lower packaging body 21.

[0036] To sum up, the embodiment of the present application is to coordinate the upper packaging body 11, the lower packaging body 21 and the elastic seal 12, so that the upper box body 10 and the lower box body 20 can be relatively fixed in position through the friction connection between the upper packaging body 11, the seal 12 and the lower packaging body 21, thereby simplifying the installation steps of the cable junction box and significantly improving the installation efficiency of the junction box.

[0037] In the installed state, the two upper packaging bodies 11 and the lower packaging body 21 form a closed cavity in the junction box, which can accommodate a gas protection medium. In some possible implementation methods of the embodiments of the present application, the operator can pre-open a through hole on the upper packaging body 11 or the lower packaging body 21, inject the protection medium through the aforementioned through hole into the junction box formed by assembling the upper box body 10 and the lower box body 20, and then use a sealing block to plug the aforementioned through hole.

[0038] As a feasible specific implementation method of the embodiment of the present application, the two upper packaging bodies 11 and the lower packaging body 21 form a closed cavity in the junction box, and the seal 12 on the contact surface of the upper packaging body 11 is inclined close to the side of the aforementioned cavity, and the thickness of the seal 12 on the contact surface of the upper packaging body 11 gradually increases in the direction from the window of the upper box body 10 to the inner wall of the cavity of the upper box body 10.

[0039] In combination with a specific usage scenario, during assembly, the thickness of the seal 12 on the upper packaging body 11 gradually increases in the direction away from the lower box body 20. As the upper box body 10 and the lower box body 20 gradually approach each other, the deformation of the seal 12 gradually increases. This allows the seal 12 to be filled between the upper packaging body 11 and the lower packaging body 21 with a larger deformation and filling degree after the upper box body 10 and the lower box body 20 are completed and assembled, thereby increasing the reliability of the friction connection between the upper packaging body 11 and the lower packaging body 21, and reducing the difficulty of initial contact installation and alignment of the upper packaging body 11 and the lower packaging body 21. On the basis of ensuring the reliability of the connection between the upper box body 10 and the lower box body 20, the installation difficulty of the operator is reduced, and the installation efficiency of the junction box is improved.

[0040] In a possible implementation of the embodiment of the present application, the lower packaging body 21 has a contact surface on one side of which a sealing groove 22 for accommodating the seal 12 can be opened. When the elastic seal 12 is deformed, part of the deformed seal 12 can be embedded in the sealing groove 22, and the seal 12 can be snapped into place through the ridges of the boundary of the sealing groove 22, thereby increasing the reliability of the connection between the upper packaging body 11 and the lower packaging body 21. On this basis, the size of the sealing groove 22 can be increased so that in the assembled state, the seal 12 of the upper packaging body 11 is embedded in the sealing groove 22, further increasing the reliability of the connection between the upper packaging body 11 and the lower packaging body 21.

[0041] As a feasible specific implementation of the embodiment of the present application, a sealing strip 40 with an adjustable shape is provided on the inner side of the groove of the upper packaging body 11 and the lower packaging body 21 .

[0042] In combination with a specific usage scenario, when the cable is connected, the cable contacts the inner side of the groove of the upper packaging body 11 and the lower packaging body 21. At this time, a shape-adjustable sealing strip 40 is provided on the inner side of the groove of the upper packaging body 11 and the lower packaging body 21 to increase the tightness of the connection between the inner side of the groove and the cable. On this basis, the width of the sealing strip 40 can be greater than the thickness of the groove to further improve the sealing of the upper packaging body 11 and the lower packaging body 21 to the cable during assembly.

[0043] As a feasible specific implementation method of the embodiment of this application, refer to Figure 5The wiring barrel 30 of the lower box body 20 extends toward the interior of the lower box body 20, and buckles 13 are provided at the openings at both ends of the upper box body 10. In the assembled state, the buckles 13 of the upper box body 10 are sleeved on the outside of the wiring barrel 30, so that the positions of the upper box body 10 and the lower box body 20 are relatively fixed.

[0044] In combination with a specific usage scenario, when in use, the operator presses down the upper box body 10, the upper packaging body 11 of the upper box body 10 and the lower packaging body 21 of the lower box body 20 are matched, and the seal 12 is embedded between the upper packaging body 11 and the lower packaging body 21 to complete the installation of the upper box body 10 and the lower box body 20. As the operator presses down the upper box body 10, the buckle 13 on the upper box body 10 will synchronously clamp the wiring barrel 30, thereby increasing the stability of the assembly of the upper box body 10 and the lower box body 20, and no additional operation is required by the operator.

[0045] In a possible implementation of the embodiment of the present application, referring to Figure 5 and Figure 6 The wiring barrel 30 includes a mounting portion 31 and a clamping portion 32. The lower box body 20 is movably connected with a mounting ring 23. In the assembled state, the end of the lower box body 20 and the mounting portion 31 of the wiring barrel 30 are embedded in the inner side of the mounting ring 23. The clamping portion 32 is located in the cavity of the lower box body 20. The buckle 13 of the upper box body 10 is clamped on the clamping portion 32 of the wiring barrel 30 to achieve the cooperation between the upper box body 10 and the lower box body 20.

[0046] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
