[0034] Combination Figure 1-Figure 11, is a schematic diagram of the principle structure of an embodiment of an outdoor waterproof and moisture-proof junction box of the present invention. The outdoor waterproof and moisture-proof junction box includes a body 1, the body 1 is in the shape of a disc, the edge of the body 1 is vertically bent upward to form a ring-shaped box wall 2, which can effectively prevent the surrounding and surface rainwater or moisture from entering, and the two ends of the symmetrical diameter of the box wall 2 are provided with bent ears 3 that are vertically bent inward, and the bent ears 3 are provided with screw holes 4, and screws 5 are movably screwed into the screw holes 4, and the screws 5 can be installed with a cover (not shown in the figure), and the body 1 is provided with a through hole 7 for the screw 5 to penetrate, which can also serve as a channel for the screw 5 to be screwed inward, so that the body 1 and the cover are installed and fastened together; the middle of the body 1 is concentrically provided with a rearward The protruding KO hole 6 is provided with a connecting head arc connection connected to the main body 1 when punching, which can not only facilitate the removal of the circular piece protruding backward, but also keep the circular piece on the hole. The KO hole 6 is provided with through holes 7 on the left and right, which can be used as a channel for the main body 1 to be fastened to the mounting body by screws. The upper and lower ends of the KO hole 6 are also provided with 4 KO holes 6 symmetrically arranged on the main body 1 on the left and right sides. The 4 KO holes symmetrically arranged on the left and right sides are provided with straight slot holes 8. The KO hole 6 provided with the straight slot holes 8 can increase the exchange channel of internal and external gases when retained. The surface of the straight slot hole 8 is provided with a pressing sheet 9 that can cover the KO hole 6 through a screw 5. The pressing sheet 9 is provided with a through hole 7 and is movably connected to the screw hole 4 of the main body 1 through the through hole 7 by the screw 5.

[0035] Preferably, in order to improve the connection strength between the main body 1 and the mounting fixed body, the concentric KO hole 6 in the middle of the main body 1 is rotated clockwise by an angle and further provided with a pair of through holes 7 identical to the through holes 7 on both sides of the KO hole 6. Specifically, the angle is 45 degrees, and can also be 62 degrees or other angles when specifically set, but it is preferable not to interfere with other parts.

[0036] Specifically, in order to prevent the pressing sheet 9 from rotating and pulling the connector of the connecting line, an arc 11 that is in contact with the inner wall of the box wall 2 and convex is provided between the pressing sheet 9 and the box wall 2. The arc 11 can be pressed against the inner circumferential surface of the box wall 2 when the pressing sheet 9 is pressed. In order to improve the rigidity and strength of the pressing sheet 9, a reinforcing rib 14 is provided under the arc 11. The reinforcing rib 14 is a long strip-shaped protrusion, which is extended from the main material of the pressing sheet 9.

[0037] Specifically, in order to increase the pressing elasticity of the pressing sheet 9 , a pair of inwardly bent spring sheets 12 are provided near the edges on both sides of the pressing sheet 9 , and the elasticity of the spring sheets 12 is fully utilized to elastically press the pressing sheet 9 onto the body 1 .

[0038] Specifically, in order to prevent the joint of the crimped connecting wire from swinging to both sides, the two sides of the through hole 7 on the pressing plate 9 are provided with convex tops 13 extending upward, which can effectively prevent the connecting wire joint from moving to both sides, play a fixing role, and further provide a spatial protection for the protective layer of the connecting wire to prevent the protective layer from being damaged by excessive pressing force.

[0039] Preferably, in order to connect a ground wire or other wires, a small hole 10 is further provided in the upper right portion of the main body 1. When the ground wire is not connected to the small hole 10, the small hole 10 can also be used as a vent to increase air circulation and keep the temperature inside and outside the box consistent.

[0040] The above-mentioned outdoor waterproof and moisture-proof junction box, the junction box and the surfaces of the matching parts are provided with an anti-rust layer or an anti-static layer, which effectively protects the service life of the main body 1.

[0041] During installation and use, first insert the power cord and the connecting wire from the through hole 7 from the back. When the through hole 7 cannot accommodate the power cord and the connecting wire, it is preferred to knock open the middle KO hole 6 concentric with the main body 1, or one or both of the upper and lower KO holes 6 can be knocked open. Note that the two holes on the diagonal are used preferentially, because the material of the KO hole 6 itself is still connected to the main body 1 and can be used as a limiter. When the main body 1 is installed and pressed on the mounting body, it can effectively prevent the power cord and the connecting wire from being excessively flattened and damaging the surface protective layer. Then, use screws 5 to pass through the through hole 7 to fasten the main body 1 to a mounting body such as a connecting frame or a steel frame, then connect the power cord and the connecting wire separately, and use the pressing sheet 9 to tighten them on the screw hole 4 of the main body 1 through the screw 5. When tightening, pay attention to the arc 11 of the pressing sheet 9 against the inner wall of the box wall 2 to prevent swinging.

[0042] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
