[0029] Example 1

[0030] Reference Figures 1-6 This embodiment provides a power distribution box that facilitates wiring and distribution, including a housing 100, a placement cavity 101 in the housing 100, a wiring groove 102 in the side wall of the housing 100 communicating with the placement cavity 101, a plate frame 103 and a mounting frame 104 alternately arranged in the placement cavity 101, a terminal block 200 on the mounting frame 104, the mounting frame 104 being connected to the side wall of the housing 100, a cavity 105 in the mounting frame 104, and a wire placement groove 106 alternately arranged in opposite directions on the mounting frame 104, with the terminal block 200 correspondingly fixed at the wire placement groove 106.

[0031] The mounting rack 104 does not contact the bottom of the placement cavity 101 and has a slot for wires to pass through. The cavity 105 is used to store the wires. Various electrical devices, such as relays and circuit breakers, are placed on the plate rack 103.

[0032] The mounting rack 104 has alternating reverse cable trays 106. Specifically, the left side of the mounting rack 104 has an upward-facing cable tray 106, followed by a cable tray 106 located to the right of the previous cable tray 106 with its opening facing downward. The next cable tray 106 continues to be arranged with its opening facing upward, and so on, forming a structure in which the cable trays 106 have alternating openings facing upward and downward. The cavity 105 is used to store the cables.

[0033] A semi-circular groove is provided on the cable tray 106, and the wire is placed in the semi-circular groove and connected to the terminal block 200.

[0034] The wire is routed from bottom to top, leading out from the cable tray 102. The plug bar 104b is pulled up, and the wire is placed into the cable tray 106 from above. The wire is pulled taut, and it enters the cavity 105. The end of the wire is placed in the cable tray 106. The insulation is removed from the end and it is cut to a suitable length. Then, the terminal block 200 is placed in the cable tray 106 to fix the end of the wire.

[0035] Furthermore, the four corners of the mounting frame 104 are provided with perforations 104a, and insertion rods 104b are provided in the perforations 104a. The insertion rods 104b are magnetically connected to the bottom of the placement cavity 101.

[0036] That is, a magnet is provided at the end of the insertion rod 104b, and the bottom surface of the placement cavity 101 is made of a magnetically attractive material, such as an iron-containing material. The insertion rod 104b can be magnetically attracted to the bottom surface of the placement cavity 101. The insertion rod 104b is used to limit the wire placed in the cavity 105 to prevent the wire from becoming tangled.

[0037] Furthermore, the terminal block 200 includes a narrow end 201 and a wide end 202. The end face of the wide end 202 is provided with a folded groove 202a. The bottom of the terminal block 200 is provided with a first arc groove 203. A pressure block 300 is connected to the bottom of the terminal block 200.

[0038] The groove 202a is L-shaped. The mounting frame 104 is provided with buckle plates 107 on both sides of the wire placement groove 106. The buckle plates 107 are set in the groove 202a to fix and limit the wiring terminal 200. The friction between the buckle plates 107 and the groove 202a is relatively large.

[0039] The pressure block 300 includes a pressure plate 301 and a top block 302 disposed on the pressure plate 301. The pressure plate 301 is provided with a second arc groove 303, and the top block 302 is embedded in the first arc groove 203. A spring 304 is provided at the end of the pressure block 300 and connected to the terminal block 200. Side strips 203a are provided on both sides of the first arc groove 203, and side grooves 302a are provided on both sides of the top block 302. The side strips 203a are embedded in the side grooves 302a. A step groove 302b is provided on the top block 302.

[0040] The second arc groove 303 is roughened and contacts the wire insulation, thus fixing the wire.

[0041] The pressure block 300 can slide along the first arc groove 203. Specifically, after the wire is processed, the terminal 200 is picked up and the pressure block 300 is placed in the wire placement groove 106. Since the width of the pressure block 300 is the same as the width of the wire placement groove 106, the terminal 200 is pushed to press against the wire. During this process, the pressure block 300 moves along the straight groove 106 to contact and press the wire insulation. The pressure block 300 does not move, the spring 304 is compressed, and the pressure force of the pressure block 300 on the wire increases. Then the terminal 200 is released and the conductive part at the end of the wire is bent. Finally, the buckle plate 107 enters the folding groove 202a.

[0042] Furthermore, the bottom of the terminal block 200 is provided with a bottom groove 204 that communicates with the first arc groove 203. A fixed shaft 204a is provided in the bottom groove 204, and a sleeve shaft 204b is provided on the fixed shaft 204a. A slanted plate 204c is provided at one end of the sleeve shaft 204b, and a horizontal plate 204d is provided at the end of the slanted plate 204c.

[0043] It should be noted that the sleeve 204b, the inclined plate 204c, and the horizontal plate 204d are made of rigid materials and are not easily deformed. The sleeve 204b can rotate on the fixed shaft 204a.

[0044] The other end of the sleeve shaft 204b is provided with a conductive copper sheet 204e. Both the narrow end 201 and the wide end 202 are provided with a terminal 205. The terminal 200 is provided with a conductive plate 206 inside, and the conductive plate 206 connects the terminal 205 and the conductive copper sheet 204e.

[0045] It should be noted that the outer part of the sleeve 204b is also provided with a conductive layer that is connected to the conductive copper sheet 204e, and can be electrically conductive.

[0046] Reference Figure 5In the initial state, the horizontal plate 204d is in the bottom groove 204. It should be noted that the sleeve shaft 204b has a cam structure, which ensures that the horizontal plate 204d is always in the bottom groove 204 when there is no upward pressure on the horizontal plate 204d. Specifically, the conductive plate 206 presses against the sleeve shaft 204b. When the horizontal plate 204d is turned upward, the cam presses the conductive plate 206 upward. When the upward force of the horizontal plate 204d is removed, the conductive plate 206 presses the cam back to its original state.

[0047] Therefore, when installing the terminal block, the pressure block 300 slides upward to press the horizontal plate 204d, and the conductive copper sheet 204e at the other end presses down to make conductive contact with the wire. Then, when the pressure block 300 moves to the position where the ladder groove 302b corresponds to the horizontal plate 204d, the horizontal plate 204d is locked in the ladder groove 302b, limiting and fixing the pressure block 300. The terminal block 200 is fixed relative to the pressure block 300, and the spring no longer exerts an outward pushing force on the terminal block 200, which ensures a tight connection with the wire and maintains the stable fixation of the terminal block 200 on the mounting bracket 106.

[0048] The terminal block 200 is also provided with a middle groove 207, and a vertical plate 208 is provided on the conductive plate 206. The vertical plate 208 is located in the middle groove 207. An extension terminal 400 is also provided at the top center of the terminal block 200. The extension terminal 400 includes an insulating frame 401 and a U-shaped conductive plate 402 provided in the insulating frame 401. The terminal block 200 is provided with a sleeve hole 209 that communicates with the middle groove 207. A conductive column tube 403 is connected to the bottom of the U-shaped conductive plate 402. A conductive side plate 404 is provided on the outside of the conductive column tube 403. An arc edge 405 is provided on the outside of the conductive side plate 404.

[0049] The vertical plate 208 is connected to the conductive plate 206. One opposite side of the insulating frame 401 is hollowed out to facilitate wiring. In the idle state, the hollowed-out part of the insulating frame faces the two terminal blocks 205. At this time, the conductive side plate 404 does not contact the vertical plate 208 for conduction. When it is necessary to expand the use, rotate the expansion terminal 400, and the conductive side plate 404 contacts the vertical plate 208 for conduction.

[0050] It should be noted that the extension terminal 400 is used for extended connection with the adjacent wiring terminal 200.

[0051] Furthermore, adjacent terminals 200 are arranged with narrow ends 201 and wide ends 202 in sequence to form a complete terminal block structure, which can be disassembled and replaced individually, offering high flexibility.

[0052] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
