[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other.

[0017] like Figure 1-4 The power distribution junction box shown includes a housing base 1 and a wiring copper component 2. The wiring copper component 2 is provided with a wire hole 21 and a locking hole 22. The housing base 1 is also provided with a pressure cover 3 and a flip cover 4. The pressure cover 3 is provided with a tool hole 32 opposite to the locking hole 22. The housing base 1 is provided with a slot 11. The pressure cover 3 is provided with a hook 31 that elastically latches against the slot 11. The flip cover 4 is hinged to a hinge groove 43 provided on the pressure cover 3, and is used to flip and fasten relative to the pressure cover 3 to cover the tool hole 32.

[0018] As a further feature of the above scheme, the pressure cap 3 is also provided with a positioning post 33, and the housing base 1 and the wiring copper part 2 are provided with positioning holes 23.

[0019] As a further feature of the above scheme, the pressure cover 3 is also provided with a retaining plate 34, the retaining plate 34 is provided with an inclined block 35, and the flip cover 4 is provided with an inclined guide surface 41 that cooperates with the inclined block 35.

[0020] As a further provision of the above scheme, a locking screw 24 is provided in the locking hole 22. The wire hole 21 and the locking hole 22 are connected on one side of the wiring copper part 2. The locking hole 22 is radially connected to the wire hole 21, and the inlet of the locking hole 22 is spaced from the bottom of the wire hole 21. The angle between the opening side of the locking hole 22 and the wire hole 21 is less than or equal to a right angle.

[0021] As a further feature of the above scheme, the width of the wiring compartment 12 on the housing base 1 for mounting the wiring copper parts 2, the pressure cover 3 and the flip cover 4 is matched with the wiring copper parts 2, the pressure cover 3 and the flip cover 4.

[0022] refer to Figure 1 and Figure 2 The junction box of this utility model includes a housing base 1, on which a plurality of wiring compartments 12 are provided. Wiring copper parts 2, pressure covers 3, and flip covers 4 are installed within the wiring compartments 12. During installation, refer to... Figure 3 The flip cover 4 shown is first inserted into the hinge shaft located at the hinge groove 43 on the pressure cover 3, as shown. Figure 2 The hinge shaft shown also has a beveled structure for easy insertion. After insertion, the beveled guide surface 41 at the front end of the flip cover 4 engages with the beveled block 35 of the clamping plate 34 on the pressure cover 3. The abutment plate on the flip cover 4 abuts against the upper end of the pressure cover 3, restricting the snapping position of the flip cover 4. When opening, the protruding plate at the upper end of the flip cover 4 is used to pull it out, and then the hinge is flipped to open the upper end of the pressure cover 3, making it convenient for the operator to insert tools to lock or loosen the wire.
