[0030] Terms such as "upper," "lower," "left," "right," and "center" used in this application are generally intended to facilitate intuitive understanding when compared with the accompanying drawings and are not intended to be absolute limitations on positional relationships in actual products. Changes to these relative positional relationships are considered within the scope of this application without departing from the technical concepts disclosed herein.

[0031] The utility model provides a junction box which is easy to assemble and disassemble. Figures 1 to 9As shown, a base 1 is provided, and the base 1 is provided with at least one group of crimping bodies 2. The number of crimping bodies 2 is determined according to the number of cables that need to be connected. In the embodiment of the present application, the number of crimping bodies 2 is three groups. The crimping bodies 2 include a first splicing body 201 and a second splicing body 202 respectively provided on the top surface of the base 1. Specifically, a fixing pin can be provided on the top surface of the base 1, and a fixing pin hole can be provided on the bottom surface of the first splicing body 201 and the second splicing body 202, and the fixing pin can be embedded in the fixing pin hole. A first receiving groove 2011 is provided on the bottom surface of the first splicing body 201, and a first handle groove 2012 connected to the first receiving groove 2011 is provided on both the left and right sides of the top surface; a second receiving groove 2021 is provided on the bottom surface of the second splicing body 202, and a second handle groove 2022 connected to the second receiving groove 2021 is provided on both the left and right sides of the top surface. The first and second components 201 and 202 are joined together by aligning the side of the first component 201 facing the second receiving slot 2021 with the side of the second component 202 facing the first receiving slot 2011. This splicing connection can also be achieved by a pin-and-pinhole connection. Thus, the first receiving slot 2011 and the second receiving slot 2021 form a lever cavity, and the left and right first handle slots 2012 and the left and right second handle slots 2022 form a pair of handle cavities, respectively. A pair of levers 3 are hingedly connected on the left and right sides between the first and second components 201 and 202 within the lever cavity. The lever body 301 of the lever 3 has a handle 302 at the top and an extrusion portion 303 at the bottom. The left and right handles 302 are movable through the left and right handle cavities, respectively, and extend out from the tops of the first and second components 201 and 202. A metal sheet 7 is installed on the top surface of the base 1, directly below the pair of levers 3. The first and second components 201, 202 on the left and right sides of the metal sheet 7 respectively have first and second cable holes 4, 5, through which the first and second cables 11, 12 to be connected are inserted. A curved third metal spring 10 is installed at the bottom of the extrusion portion 303. When the lever 3 is rotated, the third metal spring 10 presses the first and second cables 11, 12 against the top surface of the metal sheet 7.

[0032] Preferably, in order to stably and reliably fix the first cable 11 and the second cable 12 to the metal sheet 7, a first metal spring 8 is provided on the top surface of the metal sheet 7 directly below the left lever 3, and a second metal spring 9 is provided on the top surface of the metal sheet 7 directly below the right lever 3. In this way, under the extrusion of the extrusion portion 303 and the elastic force of the first metal spring 8, the second metal spring 9 and the third metal spring 10, the first cable 11 and the second cable 12 are fixed between the first metal spring 8 and the third metal spring 10, and the second metal spring 9 and the third metal spring 10.

[0033] Preferably, in order to prevent the first metal spring 8, the second metal spring 9 and the third metal spring 10 from interfering with the extrusion part 303 when it moves downward to extrude, one end of the first metal spring 8, the second metal spring 9 and the third metal spring 10 are fixedly set on the top surface of the metal sheet 7, and the other ends are free ends and can slide on the top surface of the metal sheet 7.

[0034] Preferably, in order to limit the placement of the first cable 11 and the second cable 12 and improve the visual experience during use, the base 1 in the center of the metal sheet 7 is provided with a partition beam 101, the metal sheet 7 passes through the partition beam 101, and the first metal spring 8 and the second metal spring 9 are respectively located on the left and right sides of the partition beam 101.

[0035] Preferably, in order to improve the convenience of operation, the side surfaces of the pair of handles 302 facing away from each other are provided with arc-shaped grip grooves 3021. When in use, two fingers of one hand can simultaneously move the pair of handles 302, and the cable installation and removal is very convenient and quick.

[0036] Preferably, to prevent accidental rotation of the lever 3 after the cables are installed and connected, an elastic locking ring 6 is hingedly connected to the top of the left or right handle 302. The elastic locking ring 6 is used to fasten the two components together. This is a prior art technique well known to those skilled in the art and will not be described in detail here. In this way, when the third metal spring 10 presses the first cable 11 and the second cable 12 against the top surface of the metal plate 7, the elastic locking ring 6 clamps and secures the left and right handles 302 together, thereby preventing the cables from being detached due to accidental rotation of the lever 3.

[0037] When using:

[0038] During installation and connection, insert the first cable and the second cable into the first cable hole and the second cable hole respectively, move the left and right handles to bring them closer together, and the third metal springs of the left and right levers will press the first cable and the second cable onto the metal sheet, making them connected through the metal sheet; during disassembly, move the left and right handles to move them away, and the third metal springs of the left and right levers will move away from the metal sheet, thereby loosening the first cable and the second cable from the metal sheet, and smoothly taking out the first cable and the second cable.

[0039] The present application has been described in a relatively specific and detailed manner through general explanations and specific embodiments. It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations may be made to these specific embodiments; however, as long as they do not depart from the technical concept of the present application, the technical solutions obtained by such conventional adjustments or further innovations also fall within the scope of protection of the claims of the present application.
