[0002] The junction box has the functions of protecting wires and connecting wires. The traditional junction box is made of a plastic shell with a cavity. The volume of the cavity inside the junction box is fixed, but in the actual operation process, it is often difficult to accommodate due to the increase in the number of wires and electronic components. Therefore, it is necessary to improve the traditional junction box. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is that the internal cavity of the existing junction box is fixed and cannot meet the complex operation environment, so an expandable junction box for solving the above problems is provided.

[0005] An expandable junction box, including a junction box body, one or more side walls of the junction box body are made of movable shutters;

[0006] Splicing slots and splicing strips are respectively arranged on two opposite outer side surfaces of the junction box body. The splicing slots and the splicing strips are in a shape adapted to each other and both extend along the height direction of the junction box body.

[0007] Preferably: Avoidance notches are formed on the side walls of the junction box body, and slots are formed on both opposite side walls of the avoidance notches. The movable shutters are inserted into the slots.

[0008] Preferably: A cross-sectional area with a circular, rectangular or irregular shape is arranged on the side surface of the movable shutter.

[0009] Preferably: The bottom wall of the junction box body is detachable.

[0010] Preferably: The cross-section of the junction box body is arranged as a rectangle. Jacks are arranged around the top of the junction box body and extend to the bottom of the junction box body. Rivets are riveted in the jacks, and the length of the rivets is N, where N≥1 times the height of one junction box body.

[0011] Preferably: Reinforcing ribs are arranged at the side edges of the junction box body.

[0012] The beneficial effects of the present utility model are as follows: When the volume of the cavity inside a junction box body cannot meet the installation requirements, one or more junction box bodies are spliced together through the cooperation of splicing slots and splicing strips, and then the movable shutter is removed, thereby expanding the volume of the cavity to meet complex installation requirements.

[0018] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0019] It should be pointed out that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0020] In the present utility model, unless otherwise stated, the orientations such as "upper, lower" are generally in the directions shown in the drawings, or in the vertical, perpendicular or gravitational directions; similarly, for the convenience of understanding and description, "left, right" are generally the left and right shown in the drawings; "inside, outside" refer to the inside and outside relative to the contour of each component itself, but the above orientation terms are not used to limit the present utility model.

[0021] According to Figures 1-4As shown in the figure, an expandable junction box includes a junction box body 1, and one or more side walls of the junction box body 1 are made of movable shutters 2; splicing slots 3 and splicing strips 4 are respectively arranged on two opposite outer side surfaces of the junction box body 1. The splicing slots 3 and the splicing strips 4 are adapted in shape and both extend along the height direction of the junction box body 1. When the volume of the cavity inside one junction box body 1 cannot meet the installation requirements, one or more junction box bodies 1 are spliced together through the cooperation of the splicing slots 3 and the splicing strips 4, and then the movable shutters 2 are removed, so as to expand the volume of the cavity and meet complex installation requirements.

[0022] According to Figures 1-4 As shown in the figure, avoidance notches 5 are formed on the side walls of the junction box body 1, and slots 10 are formed on both opposite side walls of the avoidance notches 5. The movable shutters 2 are inserted into the slots 10. A cross-section area 6 with a circular, rectangular or irregular shape is arranged on the side surface of the movable shutter 2.

[0023] According to Figures 1-4 As shown in the figure, the bottom wall 7 of the junction box body 1 is detachable. The cross-section of the junction box body 1 is arranged as a rectangle. Jacks 8 are arranged around the top of the junction box body 1 and extend to the bottom of the junction box body 1. Pins are riveted in the jacks 8, and the length of the pins is N, where N≥ the height of 1 junction box body 1 (when two junction box bodies 1 are spliced vertically, the length of the pins is the sum of the heights of the two junction box bodies 1). Reinforcing ribs 9 are arranged at the side edges of the junction box body 1.

[0024] Combined with Figures 1-4 As shown in the figure, the junction box body 1 is a rectangular shell with an opening at the top. According to the operation requirements, the junction box body 1 can be spliced horizontally or vertically. The periphery of the bottom wall 7 (or bottom plate) of the junction box body is clamped with the side wall (or side plate) of the junction box body 1. When splicing vertically, the bottom wall 7 can be removed. In addition, a cross-section area 6 is arranged on the movable shutter 2, and the cross-section area 6 is convenient to knock off during wire installation and is used for wire threading. Therefore, the use mode of the movable shutter 2 has diversity.
