The hinge buckle 3 adopts a flexible buckle design to prevent it from coming off. Since the bottom of the front and rear sides of the male terminal box lower cover 1 and male terminal box lower cover 2, and the top of the front and rear sides of the male terminal box upper cover 4 and male terminal box upper cover 5, are respectively movably connected with hinge buckles 3, the male terminal box upper cover 5 and male terminal box lower cover 2 can be flipped 180 degrees by the hinge buckles 3, thereby increasing the flip angle, improving the utilization of operating space and the convenience of wiring. At the same time, the right side of the inside of the male terminal box lower cover 2 and male terminal box upper cover 5 are respectively provided with corresponding toothed clamps 6, so that the wires can be fixed by the toothed clamps 6 to prevent loosening or falling off due to external pulling.
[0029] Among them, the right ends of the inner walls of the front and rear sides of the first lower cover 1 of the male terminal box are respectively fixedly installed with protruding strips 8, and the left ends of the inner walls of the front and rear sides of the second lower cover 2 of the male terminal box are respectively fixedly installed with buckle plates 9, and the inner surface of buckle plates 9 and the outer surface of protruding strips 8 are movably connected.
[0030] The presence of the protruding strip 8 and the buckle plate 9 enables the locking of the first lower cover 1 and the second lower cover 2 of the male terminal box, thereby preventing the second lower cover 2 of the male terminal box from becoming loose.
[0031] Among them, upper toothed plates 11 are fixedly installed on the front and rear ends of the bottom right side of the second upper cover 5 of the male terminal box, and lower toothed plates 10 are fixedly installed on the front and rear ends of the right side of the second lower cover 2 of the male terminal box. The lower toothed plates 10 and the upper toothed plates 11 are meshed and connected.
[0032] The upper toothed plate 11 is elastic, and due to the presence of the lower toothed plate 10 and the upper toothed plate 11, the second lower cover 2 and the second upper cover 5 of the male terminal box are locked.
[0033] Among them, the male pin terminal 7 is movably sleeved on the left side of its outer surface, and the bottom end of the female pin terminal 12 is movably connected to the lower cover 13 of the female terminal box.
[0034] The female pin terminal 12 and the lower cover 13 of the female terminal box are assembled and fixed together by a snap fastener. The presence of the male pin terminal 7 and the female pin terminal 12 enables plug-in conductivity.
[0035] The top of the lower cover 13 of the female terminal box is movably connected to the upper cover 14 of the female terminal box, and a wire clamp 15 is movably installed on the left side inside the lower cover 13 of the female terminal box.
[0036] The lower cover 13 and the upper cover 14 of the female terminal box are assembled and fixed together by snap fasteners. The wire clamp 15 is assembled and fixed to the left side inside the lower cover 13 of the female terminal box by snap fasteners, so that the wire clamp 15 can be used to clamp the wire.

[0039] Among them, the left end of the male pin terminal 7 is fixedly sleeved with a toothed clip 18.
[0040] Because of the toothed clip 18, when the operator uses a test pen or multimeter to test continuity, the toothed clip 18 can clamp the pen tip tightly, thus preventing it from falling off, without the operator needing to hold the pen tip with their hand.
[0041] Working principle and usage process of this utility model:
[0042] When assembling the female terminal box, the operator snaps the female pin terminal 12 and the wire clamp 15 into the corresponding latches on the lower cover 13 of the female terminal box, and then snaps the upper cover 14 of the female terminal box into the corresponding latches on the lower cover 13 of the female terminal box to complete the assembly. When assembling the male terminal box, the operator snaps the male pin terminal 7 into the corresponding latches on the first lower cover 1 of the male terminal box, and then connects the first lower cover 1 and the second lower cover 2 of the male terminal box using hinges 3. Similarly, the first upper cover 4 and the second upper cover 5 of the male terminal box are connected using hinges 3. Next, snap the first upper cover 4 of the male terminal box into the corresponding snap fastener on the first lower cover 1 of the male terminal box. Then, the second lower cover 2 of the male terminal box will be secured to the first lower cover 1 of the male terminal box by the protrusion 8 and the snap plate 9 to prevent the second lower cover 2 of the male terminal box from loosening. Then, the second upper cover 5 of the male terminal box and the second lower cover 2 of the male terminal box are connected by the upper tooth plate 11 and the lower tooth plate 10 to prevent the second upper cover 5 of the male terminal box from loosening. Finally, insert the male pin terminal 7 into the female pin terminal 12. The female terminal box and the male terminal box can then be assembled by the snap-fit block 16 and the snap-fit clamp 17.
[0043] In use, the light fixture is connected to the left side of the female terminal box. A high-quality hinge 3 connects the first lower cover 1 and the second lower cover 2 of the male terminal box, as well as the first upper cover 4 and the second upper cover 5. This optimizes the existing junction box hinge structure, extends the product's lifespan, and ensures stable and smooth opening and closing of the covers. Both the second lower cover 2 and the second upper cover 5 can rotate 180 degrees, completely eliminating any obstruction of the wiring operation space and providing a spacious, unobstructed operating environment for the operator. Furthermore, the increased opening angle not only improves the utilization of the operating space but also... The design allows operators to perform precise operations more conveniently during wiring, reducing operational difficulty and error rate, and meeting wiring needs in different scenarios. The toothed clamp 6 ensures that the wires are firmly fixed inside the junction box after wiring is completed when the second lower cover 2 and the second upper cover 5 of the male terminal box are closed, effectively preventing loosening or falling off due to external pulling. The addition of the toothed clamp 18 allows the test pen tip to be clamped tightly when testing continuity with a test pen or multimeter to prevent it from falling off. This eliminates the need for the operator to hold the test pen tip by hand and does not affect the plugging and connection between the male pin terminal 7 and the female pin terminal 12.
