[0026] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0027] The embodiment of the utility model provides a terminal junction box structure, such as Figure 1-4As shown, the first box body 100 and the second box body 200 are both provided with a receiving cavity 10. The receiving cavity 10 of the first box body 100 forms an opening 11 on the side of the first box body 100, and the receiving cavity 10 of the second box body 200 also forms an opening 11 on the side of the second box body 200. The receiving cavity 10 of the first box body 100 and the receiving cavity 10 of the second box body 200 are respectively used to place a terminal of a wire, and the opening 11 allows the terminal to extend out so that the two terminals can be connected. The first box body 100 is respectively provided with a first connecting arm 110 and a first connecting member 120 on both sides of its opening 11, and the second box body 200 is respectively provided with a second connecting arm 210 and a second connecting member 220 on both sides of its opening 11. The first connecting arm 110 can extend toward the second box body 200 along the docking direction, and the second connecting arm 210 can extend toward the first box body 100 along the docking direction. The opening 11 of the first box body 100 is connected to the opening 11 of the second box body 200, so that the terminals in the two accommodating chambers 10 can be connected together. The first box body 100 and the second box body 200 have the connected terminal covers arranged inside to protect the terminals, which is suitable for connecting wires with terminals. The first connecting arm 110 is detachably connected to the second connecting member 220, and the second connecting arm 210 is detachably connected to the first connecting member 120. When the first connecting arm 110 is connected to the second connecting member 220 and the second connecting arm 210 is connected to the first connecting member 120, the first box body 100 and the second box body 200 can be kept in a docking state. After the first connecting arm 110 is disassembled from the second connecting member 220 and the second connecting arm 210 is disassembled from the first connecting member 120, the first box body 100 and the second box body 200 can be separated, which facilitates the docking and disassembly of the first box body 100 and the second box body 200.

[0028] In some embodiments, the first connecting arm 110 is provided with a first through slot 111, the second connecting member 220 is provided with a second mounting hole 221 corresponding to the first through slot 111, a first fixing member 310 is provided in the first through slot 111, the first fixing member 310 is detachably fixed in the second mounting hole 221, and at the same time limits the separation of the first connecting arm 110 and the second connecting member 220, and the first connecting arm 110 and the second connecting member 220 are connected together through the first fixing member 310. When the first fixing member 310 is separated from the second mounting hole 221, it can be pulled out from the first through slot 111, and the first connecting arm 110 and the second connecting member 220 can be separated.

[0029] The second connecting arm 210 is provided with a second through slot 211 that penetrates through it, and the first connecting member 120 is provided with a first mounting hole 121 that corresponds to the second through slot 211. A second fixing member 320 is provided in the second through slot 211. The second fixing member 320 is detachably fixed in the first mounting hole 121, and at the same time limits the second connecting arm 210 from being separated from the first connecting member 120. The second connecting arm 210 and the first connecting member 120 are connected together through the second fixing member 320. When the second fixing member 320 is separated from the first mounting hole 121, it can be pulled out from the second through slot 211, and the second connecting arm 210 and the first connecting member 120 can be separated.

[0030] Further, the first fixing member 310 and the second fixing member 320 are both screws, the first mounting hole 121 and the second mounting hole 221 are both threaded holes, and the screws are detachably fixed in the corresponding threaded holes. The first through-slot 111 extends along the docking direction to the end face of the first connecting arm 110 close to the second box body 200, and the second through-slot 211 extends along the docking direction to the end face of the second connecting arm 210 close to the first box body 100, the width of the first through-slot 111 is smaller than the outer diameter of the head of the screw through it, the width of the second through-slot 211 is smaller than the outer diameter of the head of the screw through it, the width of the first through-slot 111 is larger than the outer diameter of the rod of the screw through it, and the width of the second through-slot 211 is larger than the outer diameter of the rod of the screw through it. After tightening the screw, the head of the screw can press the first connecting arm 110 tightly against the second connecting member 220 to achieve the connection between the first connecting arm 110 and the second connecting member 220, and the head of the screw can also press the second connecting arm 210 tightly against the first connecting member 120 to achieve the connection between the second connecting arm 210 and the first connecting member 120.

[0031] Since the first through groove 111 and the second through groove 211 are both open at one end in the docking direction, when connecting the first box body 100 and the second box body 200, there is no need to remove the screws from the first connecting member 120 and the second connecting member 220. It is only necessary to loosen the screws by a certain distance. During the process of docking the first box body 100 and the second box body 200 along the docking direction, the rod of the screw can slide into the first through groove 111 and the second through groove 211, which facilitates the connection between the first box body 100 and the second box body 200, and can achieve quick connection and quick disassembly.

[0032] Furthermore, the surfaces of the first connecting arm 110 located on both sides of the first through slot 111 are provided with first limiting protrusions 112 for limiting the dislocation of the screw, and the surfaces of the second connecting arm 210 located on both sides of the second through slot 211 are provided with second limiting protrusions 212 for limiting the dislocation of the screw. When the screw is locked on the first connecting arm 110 and the second connecting arm 210, the head of the screw abuts against the surfaces of the first connecting arm 110 and the second connecting arm 210, and the limiting protrusions can prevent the head of the screw from sliding, thereby preventing the screw from disengaging from the first through slot 111 and the second through slot 211, so as to ensure the stable connection between the first connecting arm 110 and the second connecting member 220 and the stable connection between the second connecting arm 210 and the first connecting member 120.

[0033] In some embodiments, the first box body 100 is provided with a side surface of an opening 11 provided with a first plug-in 131 protruding along the docking direction and a first slot 132 recessed along the docking direction, and the second box body 200 is provided with a side surface of an opening 11 provided with a second plug-in 231 protruding along the docking direction and a second slot 232 recessed along the docking direction. When the first box body 100 and the second box body 200 are docked, the first plug-in 131 is inserted into the second slot 232, and the second plug-in 231 is inserted into the first slot 132, which can achieve the effect of mutual positioning and ensure that the opening of the first box body 100 and the opening of the second box body 200 are accurately docked.

[0034] In some embodiments, a plurality of through-wire binding holes 12 are provided on the inner wall of the accommodating cavity 10 of the first box body 100 and the inner wall of the accommodating cavity 10 of the second box body 200. Binding wires or cable ties can be passed through the binding holes 12 to bind the wires connected to the terminals in the accommodating cavity 10, and then the terminals connected to the wires can be bound and fixed in the accommodating cavity 10. The terminals are not easy to shake, and the terminals of the two accommodating cavities 10 are easier to connect together.

[0035] Furthermore, two reinforcing ribs 13 are provided on the inner wall of the accommodating cavity 10 of the first box body 100 and the inner wall of the accommodating cavity 10 of the second box body 200, and the wire binding hole 12 is located between the two reinforcing ribs 13. Due to the opening of the wire binding hole 12, the structural strength of the first box body 100 and the second box body 200 at the wire binding hole 12 will be damaged. Therefore, this embodiment can improve the structural strength of the first box body 100 and the second box body 200 by adding the reinforcing ribs 13.

[0036] In some embodiments, the surface of the first box body 100 is provided with an observation port 14 connected to its accommodating cavity 10, and the surface of the second box body 200 is also provided with an observation port 14 connected to its accommodating cavity 10, so as to facilitate observation of the situation inside the accommodating cavity 10 and provide space for users to install and remove terminals.

[0037] In some embodiments, a wiring groove 15 communicating with the accommodating cavity 10 is provided on the side of the first box body 100 away from its opening 10, and a wiring groove 15 communicating with the accommodating cavity 10 is also provided on the side of the second box body 200 away from its opening 10. The wires can pass through the wiring groove 15 to facilitate wiring and avoid bending of the wires.
