Connecting holes 47 are provided inside the lower protective shell 44 and the upper protective shell 45. Fixing bolts 48 are movably installed inside the connecting holes 47.
[0024] The lower protective shell 44 and the upper protective shell 45 are inserted into the slot 43 on the outside of the alignment frame 41. The lower protective shell 44 and the upper protective shell 45 are fastened together by the fixing bolt 48 through the connection hole 47 provided in the lower protective shell 44 and the upper protective shell 45. The abutment 46 in the lower protective shell 44 and the upper protective shell 45 abuts against the outside of the input and output wiring 3. As the lower protective shell 44 and the upper protective shell 45 are connected and tightened, the input and output wiring 3 is moved inward toward the box 1, squeezing the sealing ring 42 in the alignment frame 41 to ensure the tightness of the connection of the input and output wiring 3, thereby improving the sealing performance at its interface. At the same time, the lower protective shell 44 and the upper protective shell 45 cover the connection to reduce the impact of water source.
[0025] like Figure 4 and Figure 5 As shown, an inner protruding edge 11 and an outer protruding edge 13 are fixedly connected to the upper part of the inner and outer sides of the box body 1, respectively. Fixing holes 12 are opened at the four corners of the inner protruding edge 11, and a groove 14 is opened at the top of the inner protruding edge 11. A sealing ring 15 is movably engaged inside the groove 14. A sealing ring 16 is movably engaged at the top of the outer protruding edge 13. A pressing edge 51 and a pressing edge 52 are fixedly connected to the bottom of the box cover 5. The pressing edge 51 is movably engaged inside the groove 14, and the pressing edge 52 is movably engaged outside the box body 1. A fixing bolt 53 connected to the box body 1 is movably installed on the top of the box cover 5.
[0026] The lid 5 is snapped onto the top of the box body 1. The first pressing edge 51 is snapped onto the inner side of the box body 1, and the second pressing edge 52 is snapped onto the outer side of the box body 1. The first pressing edge 51 is snapped into the groove 14. The second fixing bolt 53 is screwed from above the lid 5 into the fixing hole 12 to fix the lid 5 to the box body 1. The first pressing edge 51 and the second pressing edge 52 are respectively pressed on the sealing ring 15 and the third sealing ring 16. The sealing ring 15 and the third sealing ring 16 work together to improve the sealing effect.
[0027] like Figure 2 and Figure 3 As shown, both the lower protective shell 44 and the upper protective shell 45 have locking strips on their inner sides that correspond to the locking slot 43.
[0028] The lower protective shell 44 and the upper protective shell 45 are symmetrically arranged on the outside of the alignment frame 41.
[0029] The locking strip allows the lower protective shell 44 and the upper protective shell 45 to be inserted into the slot 43 from below and above, facilitating alignment and locking, and covering the input / output wiring 3.
[0030] like Figure 3 As shown, both the lower protective shell 44 and the upper protective shell 45 have abutment blocks 46 fixedly connected inside, and the abutment blocks 46 abut against the outside of the input / output wiring 3.
[0031] By abutting the outside of the input / output wiring 3 with the abutment block 46, the input / output wiring 3 is pushed inward, thereby pressing the input / output wiring 3 against the sealing ring 42 inside the alignment frame 41 to improve the sealing performance.
[0032] like Figure 3 As shown, the inner sides of the lower protective shell 44 and the upper protective shell 45 are provided with a second slot 49, and a sealing strip 410 is movably engaged inside the second slot 49.
[0033] The card slot 49, in conjunction with its internal sealing strip 410, is positioned on the outside of the input / output wiring harness 3 to reduce the entry of the water source wiring harness.
[0034] like Figure 4 As shown, the position of fixing bolt 2 53 corresponds to fixing hole 12, and fixing bolt 2 53 is threaded into the inside of fixing hole 12.
[0035] By fixing bolt 2 53 corresponding to fixing hole 12 and threaded into fixing hole 12, the box cover 5 is locked and fixed to the top of box body 1.
[0036] like Figure 4 As shown, the first pressing edge 51 and the second pressing edge 52 abut against the top of the second sealing ring 15 and the third sealing ring 16, respectively.
[0037] By pressing the first edge 51 and the second edge 52 against the top of the second sealing ring 15 and the third sealing ring 16, two layers of waterproof sealing are provided from the inside and outside by pressing the second sealing ring 15 and the third sealing ring 16, thereby improving the waterproof effect.
[0038] The working principle of this waterproof electrical control box will be explained in detail below.
[0039] like Figures 1 to 5 As shown, the input / output cables 3 are connected to the interior of the housing 1 through the mounting ports 2 on both sides of the housing 1. Then, the lower protective shell 44 and upper protective shell 45 are installed from the upper and lower sides of the alignment frame 41. The lower and upper protective shells 44 and 45 are inserted into the slots 43 on the outside of the alignment frame 41, and their inner sides are fitted together. Fixing bolts 48 are used to secure the lower and upper protective shells 44 and 45 through the connecting holes 47 inside them. The abutments 46 inside the lower and upper protective shells 44 and 45 abut against the outside of the input / output cables 3. As the lower and upper protective shells 44 and 45 tighten, they push the input / output cables 3 inward toward the housing 1, compressing the inside of the alignment frame 41. The sealing ring 42 ensures the tightness of the input / output wiring 3 connection, thereby improving the sealing performance. At the same time, the sealing strip 410 installed in the inner groove 49 of the lower protective shell 44 and the upper protective shell 45 is engaged with the wire harness of the input / output wiring 3, reducing the contact of water source with the joint of the input / output wiring 3. The cover 5 is engaged with the top of the box body 1. The pressure edge 51 is engaged with the inner side of the box body 1, and the pressure edge 52 is engaged with the outer side of the box body 1. The pressure edge 51 is engaged with the groove 14. The cover 5 is fixed to the box body 1 by screwing the fixing bolt 53 from the top of the cover 5 into the fixing hole 12. The pressure edge 51 presses the sealing ring 15 in the groove 14, and the pressure edge 52 presses the sealing ring 16 above the outer protrusion 13, thereby improving the sealing effect.
[0040] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
