Detailed Description
Example 1:
referring to fig. 1-6, a junction box with a lead sealing structure includes an upper cover 1 and a base 2, the upper cover 1 and the base 2 form an accommodating cavity 21, and a wire can be fixed in the accommodating cavity 21 to form an electrical connection effect.
Here, the upper cover 1 is matched with the base 2, and a waterproof structure can be arranged inside the upper cover.
Be equipped with fixed column 22 on the base 2, be equipped with nut 23 on the fixed column 22 top, here nut 23 specifically is for placing on the mould, directly moulds plastics on base 2 for nut 23 firmly fixes on fixed column 22, prevents moreover that nut 23 and base 2 from taking place the phenomenon of skidding in fastening process. Further, preferably, the nut 23 is provided with protrusions 24 distributed in an array, and during the injection molding process, the adhesive extends between the two protrusions 24 to enhance the connection effect between the nut 23 and the base 2, wherein the protrusions 24 are preferably arranged in a triangular shape. It should be noted that the nut 23 is provided with an internally threaded hole, which is not shown in the drawings, but should be known to those skilled in the art.
The upper cover 1 is provided with a first lead sealing hole 11 and a through hole 12, wherein the first lead sealing hole is generally used for the lead sealing piece 3 to extend into the accommodating cavity 21, and the through hole 12 and the nut 23 are coaxially arranged. The first lead sealing hole 11 is matched with the second lead sealing hole on the head, and the first lead sealing hole and the second lead sealing hole are also coaxially arranged, so that the lead sealing fixing effect is formed.
