[0025] Reference Figures 1 to 3 , a power supply box convenient for wiring, comprising a box body 10, a circuit board 20, a connection terminal 30 and an end cover 40;

[0026] The box body 10 is provided with at least one wiring slot 50 and a rotation hole 51 and a positioning hole 61 provided on both sides of the wiring slot 50;

[0027] The circuit board 20 is disposed in the box body 10;

[0028] The connection terminal 30 is placed in the connection slot 50 and electrically connected to the circuit board 20 for connecting to an external cable;

[0029] A rotating shaft 52 and a positioning block 62 are provided on the end cover 40. The rotating shaft 52 is inserted into the rotating hole 51. The positioning block 62 can be inserted into the positioning hole 61 when the end cover 40 closes the wiring slot 50 to maintain a closed state; or the positioning block 62 can abut against the upper end surface of the box body 10 when the box body 10 opens the wiring slot 50 to maintain an open state.

[0030] In the present invention, the insulating box 80 is composed of an upper insulating sheet and a lower insulating sheet that are inserted into each other. When assembling, the circuit board 20 is first placed on the lower insulating sheet and connected to the lower cover 12 by bolts. At the same time, at least part of the terminal block 30 is inserted into the wiring slot 50, so that the user can insert the terminal block 30 into the wiring slot 50 after the end cover 40 is rotated open. Specifically, one end of the end cover 40 is provided with a rotating shaft 52, and the middle section of the end cover 40 is provided with a positioning block 62. The user can pull the other end of the end cover 40 to rotate the end cover 40 around the rotating shaft 52. The positioning block 62 first moves from the fixed position. The end cover 40 is disengaged from the positioning hole 61 until the end cover 40 is rotated to the positioning block 62 and passes the upper end surface of the box body 10. At this time, even if the end cover 40 falls back toward the wiring slot 50, the positioning block 62 will abut against the upper end surface of the box body 10, thereby limiting the end cover 40 from continuing to fall back, thereby maintaining the opening angle of the end cover 40; the user does not need to apply additional force to the end cover 40 to maintain the angle of the end cover 40; the advantage of the utility model is that the end cover is rotated by the above structure to open the wiring slot, and after the end cover is opened, its open state can be maintained by the cooperation of the positioning block and the box body, thereby facilitating the user to connect the wires, and having very good practicality.

[0031] In one embodiment, a support column 70 is provided on the end cover 40, and a positioning block 62 is provided on the support column 70 to expand the maximum opening angle that the end cover 40 can maintain; the length of the support column 70 determines the maximum angle that the end cover 40 can maintain after opening.

[0032] In one embodiment, a frill is provided on the end cover 40 to form the rotating shaft 52 ; this configuration can simplify the production steps and also reduce material costs.

[0033] In one embodiment, a guide arc surface 63 is provided on the positioning block 62; this setting not only enables the positioning block 62 to slide into or out of the positioning hole 61 better, but also produces an elastic and frustrating feel, thereby preventing the end cover 40 from opening automatically.

[0034] In one embodiment, a power supply box that is easy to connect to the wiring further includes an insulating box 80 wrapped around the circuit board 20; the insulating box 80 is made of a high-temperature resistant insulating film material, and when placed in the circuit board 20, it has insulating, heat-conducting, and flame-retardant effects.

[0035] Preferably, the circuit board 20 is connected to the box body 10 via a bolt connection structure 91 .

[0036] In one embodiment, the box body 10 includes an upper cover 11 and a lower cover 12 connected to the upper cover 11 via a detachable structure 92 .

[0037] Preferably, the detachable structure 92 is configured as a snap-fit ​​structure.

[0038] Of course, the present invention is not limited to the above-mentioned embodiments. Those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications and substitutions are all included in the scope defined by the claims of this application.
