The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0029] Example 1

[0030] Reference Figure 1 to Figure 6 The present embodiment provides a distribution box for convenient wiring and distribution, including a shell 100, a placement cavity 101 is provided in the shell 100, a wiring groove 102 is provided in the side wall of the shell 100 and communicates with the placement cavity 101, a plate rack 103 and a placement rack 104 are alternately provided in the placement cavity 101, a wiring terminal 200 is provided on the placement rack 104, the placement rack 104 is connected to the side wall of the shell 100, a cavity 105 is provided in the placement rack 104, and a wiring groove 106 is alternately and reversely provided on the placement rack 104, and the wiring terminal 200 is fixed at the wiring groove 106 accordingly.

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

[0032] Wire grooves 106 are alternately arranged on the placement rack 104 in reverse order. Specifically, a wire groove 106 is arranged on the left side of the placement rack 104 with an opening upward, followed by a subsequent wire groove arranged on the right side of the previous wire groove 106 with an opening downward, and the subsequent wire groove is further arranged with an opening upward, and these are arranged in sequence to form a structure in which the wire grooves 106 are alternately arranged with one opening upward and the other opening downward, and the cavity 105 is used to store wires.

[0033] The wire slot 106 is provided with a semicircular groove, and the wire is arranged in the semicircular groove and connected to the connection terminal 200 .

[0034] The wires are routed from bottom to top and led out from the wiring trough 102. The plug 104b is pulled up and the wires are placed into the wiring trough 106 from above. The wires are tightened and enter the cavity 105. The ends of the wires are placed in the wiring trough 106. The insulation of the ends is removed and cut to a suitable length. Then, the terminal 200 is placed in the wiring trough 106 to fix the ends of the wires.

[0035] Furthermore, through holes 104 a are provided at four corners of the placement frame 104 , and insertion rods 104 b are provided in the through holes 104 a . The insertion rods 104 b 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 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 being scattered.

[0037] Furthermore, the connecting terminal 200 includes a narrow end 201 and a wide end 202 , a folding groove 202 a is provided on the end surface of the wide end 202 , a first arc groove 203 is provided at the bottom of the connecting terminal 200 , and a pressing block 300 is connected to the bottom of the connecting terminal 200 .

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

[0039] The pressing block 300 includes a pressing plate 301 and a top block 302 arranged on the pressing plate 301, a second arc groove 303 is arranged on the pressing plate 301, the top block 302 is embedded in the first arc groove 203, a spring 304 is arranged at the end of the pressing block 300 to connect with the connecting terminal 200; side strips 203a are arranged on both sides of the first arc groove 203, side grooves 302a are arranged on both sides of the top block 302, and the side strips 203a are embedded in the side grooves 302a; a ladder groove 302b is arranged on the top block 302.

[0040] The second arc groove 303 is roughened, and the second arc groove 303 contacts the insulation skin of the wire and fixes the wire.

[0041] The pressing block 300 can slide along the first arc groove 203. Specifically, after the wire is processed, pick up the terminal 200 and place the pressing block 300 in the wire groove 106. Since the width of the pressing block 300 is consistent with the width of the wire groove 106, the terminal 200 is pushed to be squeezed toward the wire. During this process, the pressing block 300 moves along the linear groove 106 to contact and squeeze the wire insulation, squeezing and pushing the terminal 200. The pressing block 300 does not move, the spring 304 is compressed, and the clamping force of the pressing block 300 on the wire increases. Then the terminal 200 is released and the conductive part of the wire end is bent, and finally the buckle plate 107 enters the folding groove 202a.

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

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

[0044] A conductive copper sheet 204e is disposed at the other end of the sleeve shaft 204b, and terminal heads 205 are disposed on both the narrow end 201 and the wide end 202. A conductive plate 206 is disposed inside the terminal block 200, and the conductive plate 206 connects the terminal head 205 and the conductive copper sheet 204e.

[0045] It should be noted that the outer portion of the sleeve shaft 204b is also provided with a conductive layer connected to the conductive copper sheet 204e to enable electrical conduction.

[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 is a cam structure, so that when there is no force pressing the horizontal plate 204d upward, the horizontal plate 204d is always in the bottom groove 204. It is specifically realized that the conductive plate 206 is pressed and contacted with the sleeve shaft 204b. When the horizontal plate 204d is facing upward, the cam presses the conductive plate 206 upward, and 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 pressing block 300 slides upward to squeeze the horizontal plate 204d, and the conductive copper sheet 204e at the other end is pressed down to make conductive contact with the wire. Then, when the pressing block 300 moves to the ladder groove 302b corresponding to the horizontal plate 204d, the horizontal plate 204d is stuck in the ladder groove 302b, limiting and fixing the pressing block 300, and the terminal block 200 is relatively fixed to the pressing block 300. The spring no longer has an outward thrust on the terminal block 200, which not only ensures a close connection with the wire, but also keeps the terminal block 200 stably fixed on the mounting frame 106.

[0048] A middle groove 207 is also provided in the connecting terminal 200, a vertical plate 208 is provided on the conductive plate 206, and the vertical plate 208 is arranged in the middle groove 207. An extended terminal 400 is also provided in the middle of the top of the connecting terminal 200, and the extended terminal 400 includes an insulating frame 401 and a U-shaped conductive plate 402 arranged in the insulating frame 401; a sleeve hole 209 is provided on the connecting terminal 200 to communicate with the middle groove 207, and a conductive column tube 403 is connected to the bottom of the U-shaped conductive plate 402, and a conductive side plate 404 is provided on the outer side of the conductive column tube 403, and an arc edge 405 is provided on the outer side of the conductive side plate 404.

[0049] The vertical plate 208 is connected to the conductive plate 206, and an opposite side of the insulating frame 401 is hollowed out for easy wiring. In the idle state, the hollowing of the insulating frame faces the two wiring heads 205. At this time, the conductive side plate 404 is not in contact with the vertical plate 208 for conduction. When it needs to be expanded for use, the expansion terminal 400 is rotated, and the conductive side plate 404 is in contact with the vertical plate 208 for conduction.

[0050] It should be noted that the extension terminal 400 is used to perform an extension connection with the adjacent connection terminal 200 .

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

[0052] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
