This compresses the second elastic bending portion, clamping the branch wire between the first branch end of the branch spring and one side of the branch interface, thus securing the branch wire. In this way, the components inside the junction box do not require bolts for positioning and connection, and the main wire and branch wires do not need to be bolted to their corresponding positions in the junction box.

Figure 4 This is a schematic diagram of the structure of the main conductor and the branch conductor provided in an embodiment of the present invention. Figure 5 This is a schematic diagram of the internal structure of a junction box provided in an embodiment of the present invention, in conjunction with reference to the reference. Figures 1-5As shown, the junction box includes a housing 1, a main conductor 2, branch conductors 3, a main conductor tension spring 4, and multiple branch conductor tension springs 5; the main conductor 2, branch conductors 3, main conductor tension spring 4, and each branch conductor tension spring 5 are all housed within the housing 1; the main conductor tension spring 4 includes a first main conductor end 41, a second main conductor end 42, and a first elastic bending portion 43; the first main conductor end 41 and the second main conductor end 42 are opposite to each other, and the first elastic bending portion 43 connects the first main conductor end 41 and the second main conductor end 42; the main conductor 2 is provided with a main conductor interface 21; at least a portion of the first main conductor end 41 and the second main conductor end 42 are located within the main conductor interface 21, and the first main conductor end 41 and the second main conductor end 42 respectively abut against opposite sides of the main conductor interface 21, and the first elastic bending portion 43 is located on the side of the main conductor 2 near the upper surface of the housing 1; the branch conductor tension spring 5 includes a first branch conductor end 51, a second branch conductor end 52, and a first elastic bending portion 43. Two elastic bending portions 53, the first branch end 51 and the second branch end 52 are opposite to each other, and the second elastic bending portion 53 connects the first branch end 51 and the second branch end 52; the branch conductor 3 is provided with a plurality of branch interfaces 31 arranged in an array; at least a portion of the first branch end 51 and the second branch end 52 of each branch tension spring 5 are located in each branch interface 31 in a one-to-one correspondence, and the first branch end 51 and the second branch end 52 respectively abut against the opposite sides of the branch interface 31, and the second elastic bending portion 53 is located on the side of the branch conductor 3 near the upper surface of the housing 1; the upper surface of the housing 1 is provided with a main line socket 11 and a plurality of branch sockets 12; in the direction perpendicular to the upper surface of the housing 1, the main line socket 11 covers at least a portion of the first main line end 41; each branch socket 12 covers at least a portion of each first branch end 51; the main conductor 2 and the branch conductor 3 are electrically connected.

[0050] The housing 1 is made of flame-retardant material. In some embodiments, the housing 1 should also have waterproof and explosion-proof characteristics. The housing 1 is used to protect and isolate the various components inside the junction box.

[0051] The main wire tension spring 4 and the branch wire tension spring 5 are made of elastic material. The first main wire end 41 and the second main wire end 42 of the main wire tension spring 4 are opposite to each other and connected by a first elastic bending portion 43. When the first main wire end 41 and the second main wire end 42 are subjected to force and move closer or further away from each other, the first elastic bending portion 43 generates a force in the opposite direction to the force. When at least a portion of the main wire tension spring 4 is located within the main wire interface 21 of the main wire conductor 2, the first main wire end 41 and the second main wire end 42 of the main wire tension spring 4 are subjected to force and move closer to each other, so that the first main wire end 41 and the second main wire end 42 can respectively connect with the main wire interface 21. The two sides of the wire splitting spring 5 abut against each other; similarly, the first wire splitting end 51 and the second wire splitting end 52 of the wire splitting spring 5 are opposite to each other and connected by the second elastic bending part 53. When the first wire splitting end 51 and the second wire splitting end 52 are subjected to force and move closer or further away from each other, the second elastic bending part 53 generates a force in the opposite direction of the force. When at least a part of the wire splitting spring 5 is located in the wire splitting interface 31 of the wire splitting conductor 3, the first wire splitting end 51 and the second wire splitting end 52 of the wire splitting spring 5 are subjected to force and move closer to each other, so that the first wire splitting end 51 and the second wire splitting end 52 can abut against the two sides of the wire splitting interface 31 respectively.

[0052] The first elastic bending portion 43 of the main wire tension spring 4 is located on the side of the main wire conductor 2 near the upper surface of the housing 1. The upper surface of the housing 1 is provided with a main wire insertion hole 11. In a direction perpendicular to the upper surface of the housing 1, the main wire insertion hole 11 covers at least a portion of the first main wire end 41. This allows the main wire to apply a force to the first main wire end 41 when inserted into the main wire insertion hole 11, bringing the first main wire end 41 closer to the second main wire end 42. This causes the first elastic bending portion 43 to generate a force in the opposite direction to the applied force, thereby clamping the main wire between the first main wire end 41 and the main wire interface 21 to secure the main wire and enable quick insertion and removal of the main wire. Similarly, The second elastic bending portion 53 of the wire splitting spring 5 is located on the side of the wire splitting conductor 3 near the upper surface of the housing 1. The upper surface of the housing 1 is provided with a plurality of wire splitting holes 12. In the direction perpendicular to the upper surface of the housing 1, each wire splitting hole 12 covers at least a portion of each first wire splitting end 51, so that when the wire splitting is inserted into the wire splitting hole 12, the wire splitting can apply a force to the first wire splitting end 51, causing the first wire splitting end 51 to move closer to the second wire splitting end 52, so that the second elastic bending portion 53 generates a force in the opposite direction of the applied force, thereby clamping the wire splitting end 51 and the side of the wire splitting interface 31 to fix the wire splitting, thereby realizing the quick insertion and removal of the wire splitting.

[0053] The branch conductor 3 is provided with multiple branch interfaces 31 arranged in an array. Figure 4 and Figure 5This example only illustrates the case where the branch conductor 3 is provided with two rows of nine branch interfaces 31. In other exemplary embodiments, the branch conductor 3 may also include two rows of six or three rows of five branch interfaces 31. It is understood that this embodiment does not specifically limit the array arrangement and number of branch interfaces 31 in the branch conductor 3. The array arrangement and number of branch interfaces 31 in the branch conductor 3 can be set according to actual needs, as long as the main inventive point of this embodiment can be achieved.

[0054] The main conductor 2 and the branch conductor 3 are made of conductive material and are electrically connected. In an exemplary embodiment, the main conductor 2 and the branch conductor 3 can be integrally formed.

[0055] In this embodiment, the branch conductor, main conductor, main wire spring, and multiple branch wire springs are all housed within the housing. At least a portion of the first and second main wire ends of the main wire spring are located within the main wire interface of the main conductor, and the first and second main wire ends respectively abut against opposite sides of the main wire interface. The first elastic bending portion of the main wire spring is located on the side of the main conductor near the upper surface of the housing. A main wire insertion hole is provided on the upper surface of the housing. In a direction perpendicular to the upper surface of the housing, the main wire insertion hole covers at least a portion of the first main wire end of the main wire spring, so that when the main wire is inserted into the main wire insertion hole, the main wire can compress the first elastic bending portion through the first main wire end of the main wire spring, thereby causing the first main wire end of the main wire spring to press against the main wire interface. The wire clamps secure the main wire. Correspondingly, at least a portion of the first and second branch ends of each branch spring are located within the branch interfaces of the branch conductor, with the first and second branch ends of the branch springs abutting against opposite sides of the branch interfaces. The second elastic bending portion of the branch spring is located on the side of the branch conductor near the upper surface of the housing. The upper surface of the housing has multiple branch insertion holes. In a direction perpendicular to the upper surface of the housing, each branch insertion hole covers at least a portion of the first branch end, allowing the branch wire to be compressed by the corresponding first branch end of the branch spring when inserted into the insertion hole. This compresses the second elastic bending portion, clamping the branch wire between the first branch end of the branch spring and one side of the branch interface, thus securing the branch wire. In this way, the components inside the junction box do not require bolts for positioning and connection, and the main wire and branch wires do not need to be bolted to their corresponding positions in the junction box. This allows for quick insertion and removal of the main wire and branch wires, making it convenient to use and improving efficiency.

[0056] In an optional embodiment, a marking groove 13 may also be provided on one side of the branch socket 12 and the main socket 11 of the housing 1. The marking groove 13 can be marked by marking modules such as marking strips, or by text printing or pad printing, to meet the marking needs of different users.

[0057] Optional, Figure 6 This is an exploded view of a junction box provided in an embodiment of the present invention. (Reference) Figure 6 As shown, the junction box also includes a support member 6 and a support shaft 7; the support member 6 is located on the side of the junction conductor 3 near the upper surface of the housing 1; the support member 6 is provided with a plurality of openings 61 arranged in an array; each opening 61 is provided in a one-to-one correspondence with each junction interface 31; at least a portion of each junction tension spring 5 is provided in each opening 61; the side of the support member 6 away from the junction conductor 3 is also provided with a plurality of grooves 62; the support shaft 7 is placed in each groove 62; at least a portion of the second elastic bending portion 53 of each junction tension spring 5 surrounds the support shaft 7.

[0058] The support shaft 7 can be made of plastic or metal. The support member 6 is provided with multiple grooves 62, which are arranged sequentially along the arrangement direction of each branch tension spring 5. The support shaft 7 passes through the area below the second elastic bending part 53 of the branch tension spring 5 to support the branch tension spring 5.

[0059] In this embodiment, at least a portion of each branch spring 5 is correspondingly disposed in each of the openings 61 arranged in the array of the support members 6, and each opening 61 of the support members 6 is correspondingly disposed in each of the branch interfaces 31 of the branch conductor 3. Thus, each branch spring 5 can be relatively fixed in the direction of extension of the branch conductor 3 through each opening 61 of the support members 6. At the same time, a groove 62 is provided on the side of the support members 6 away from the branch conductor 3, and the support shaft 7 is placed in each groove 62. At least a portion of the second elastic bending portion 53 of each branch spring 5 surrounds the support shaft 7, so that the support shaft 7 can support each branch spring 5. Thus, each branch spring 5 can be relatively fixed in the direction perpendicular to the extension of the branch conductor 3 through the support shaft 7. In this way, through the cooperation of the support shaft 7 and the support members 6, the branch spring 5 will not shift when the branch wire is inserted or removed, so as to ensure the stability and support capacity of the branch spring 5 and improve the reliability of the junction box.

[0060] In an alternative embodiment, reference Figures 4-6 As shown, the main conductor 2 may include a support portion 22, at least a portion of which is located within the main interface 21. The support portion 22 is used to support the main tension spring 4, thereby ensuring the stability and support capacity of the main tension spring 4 and improving the reliability of the junction box.

[0061] Optional, continue to refer to Figure 4 As shown, the branch conductor 3 is provided with at least two riveting holes 32; the main conductor 2 is provided with at least two riveting posts 23; each riveting post 23 is embedded in the riveting hole 32 in a corresponding manner to realize the riveting or welding between the branch conductor 3 and the main conductor.

[0062] It is understandable that the number of rivet holes 32 and rivet posts 23 can be equal or unequal, as long as at least two rivet posts 23 can be embedded in at least two rivet holes 32 to fix the branch conductor 3 and the main conductor 2. Figure 4 The example shows a branch conductor 3 with 18 riveting holes 32 arranged in sequence, and a main conductor 2 with two riveting posts 23, wherein the two riveting posts 23 are respectively embedded in two riveting holes 32 near the edge of the branch conductor 3. In other embodiments, the riveting holes 32 and the riveting posts 23 may have other arrangements, which are not limited in this embodiment.

[0063] Optional, see reference Figure 6 As shown, the junction box also includes a main line button 8 and multiple branch line buttons 9; the upper surface of the housing 1 also includes a main line button hole 14 and multiple branch line button holes 15; the main line button 8 includes a first part 81 and a second part 82, the first part 81 abuts against the first main line end 41 of the main line tension spring 4, the second part 82 is located on the side of the first part 81 away from the main line tension spring 4, and at least part of the second part 82 protrudes out of the main line button hole 14; each branch line button 9 includes a third part 91 and a fourth part 92, the third part 91 of each branch line button 9 abuts against the first branch line end 51 of each branch line tension spring 5, the fourth part 92 of each branch line button 9 is located on the side of each third part 91 away from the branch line tension spring 5, and at least part of the fourth part 92 protrudes out of the branch line button hole 15.

[0064] The main cable button 8 is used to assist in removing the main cable, and the branch cable button 9 is used to assist in removing the branch cable. Specifically, when the main cable needs to be removed, the second part 82 of the main cable button 8 is pressed, which applies a force to the first end 41 of the main cable, bringing it closer to the second end 42. This compresses the main cable tension spring 4, releasing the main cable and allowing it to be pulled out of the main cable socket 11. Similarly, when the branch cable needs to be removed, the branch cable button 9 is pressed, which applies a force to the first end 51 of the branch cable, bringing it closer to the second end 52. This compresses the branch cable tension spring 5, releasing the branch cable and allowing it to be pulled out of the branch cable socket 12.

[0065] In one optional embodiment, since the first portion 81 abuts against the first main wire end 41 of the main wire tension spring 4, the first portion 81 of the main wire button 8 can be configured as a conical structure, so that the main wire can be pulled out by pressing the second portion 82 of the main wire button 8 with a small force, thereby improving the user experience. In another optional embodiment, the third portion 91 of the splitter button 9 can also be configured as a conical structure, so that the splitter can be pulled out by pressing the fourth portion 92 of the splitter button 9 with a small force, thereby improving the user experience.

[0066] Optional, see reference Figure 1 , Figure 2 and Figure 6 As shown, the housing 1 also includes a test socket 16. The test socket 16 and the main line socket 11 are both located on one side of the branch line socket 12. The test socket 16 covers at least part of the main line conductor, so that the ability of the junction box to transmit signals can be tested without unplugging the main line or the branch line, making the junction box easy to use and improving efficiency.

[0067] Optional, Figure 7 This is a front view of a junction box provided in an embodiment of the present invention. Figure 8 This is a rear view of a junction box provided in an embodiment of the present invention, with reference to... Figure 1 , Figure 2 ,as well as Figures 6-8 As shown, the housing 1 includes an upper housing 01 and a lower housing 02. The upper housing 01 includes multiple snap-fit ​​holes 011, and the lower housing 02 includes multiple snap-fits 021 that correspond one-to-one with each snap-fit ​​hole 011. Each snap-fit ​​021 engages with each snap-fit ​​hole 011, so that the upper housing 01 and the lower housing 02 can be engaged to complete the assembly, thereby improving the installation efficiency of the junction box.

[0068] It should be noted that, Figure 1 , Figure 2 ,as well as Figures 6-8 This example only illustrates the arrangement of the snap-fit ​​holes 011 sequentially on two opposite sides of the upper housing 01 and the snap-fit ​​021 sequentially on two opposite sides of the lower housing 02. In other embodiments, the snap-fit ​​021 and snap-fit ​​holes 011 can be arranged in other ways. For example, all four sides of the upper housing 01 may include snap-fit ​​holes 011, and all four sides of the lower housing 02 may include snap-fit ​​021. This embodiment does not limit this. Furthermore, this embodiment does not limit the specific number of snap-fit ​​021 and snap-fit ​​holes 011, as long as it can enable the upper housing 01 and the lower housing 02 to engage accordingly to complete the assembly of the junction box.

[0069] Optional, Figure 9 This is a left view of a junction box provided in an embodiment of the present invention. Figure 10 This is a right view of a junction box provided in an embodiment of the present invention, in conjunction with reference to [reference needed]. Figure 1 , Figure 2 , Figure 6 , Figure 9 and Figure 10As shown, the first side surface of the housing 1 is provided with a first dovetail groove 171 and a first dovetail hook 172; the second side surface of the housing 1 is provided with a second dovetail hook 173 and a second dovetail groove 174; the first side surface and the second side surface are two opposite side surfaces. In the direction from the first side surface to the second side surface, the first dovetail groove 171 and the second dovetail hook 173 overlap, and the first dovetail hook 172 and the second dovetail groove 174 overlap, so that multiple junction boxes can be connected together, improving the reliability and stability when multiple junction boxes are placed.

[0070] Optional, continue to refer to Figure 1 , Figure 2 , Figure 6 , Figure 9 and Figure 10 As shown, the first side surface of the housing 1 is provided with at least one anti-loosening groove 181; the second side surface of the housing 1 is provided with at least one anti-loosening buckle 182; the first side surface and the second side surface are two opposite side surfaces, and in the direction from the first side surface to the second side surface, each anti-loosening groove 181 and each anti-loosening buckle 182 overlap in a one-to-one correspondence, thereby improving the tightness when multiple junction boxes are spliced ​​and preventing two adjacent junction boxes from separating.

[0071] Optional, Figure 11 This is a schematic diagram of the structure of the base provided in an embodiment of the present invention. Figure 12 This is a schematic diagram of the lower housing structure provided in an embodiment of the present invention. Figure 13 This is a bottom view of the junction box provided in an embodiment of the present invention, in conjunction with reference to the reference. Figures 11-13 As shown, the junction box also includes a base 10, which includes at least one guide rib 101; the lower surface of the housing 1 includes at least one guide groove 191, and each guide groove 191 is slidably connected to each guide rib 101, so that the housing 1 can slide in the base 10, which is beneficial to improving the flexibility of the junction box.

[0072] It is understood that the base 10 includes at least one guide rib 101, which may include one guide rib 101 or multiple guide ribs 101; the lower surface of the housing 1 includes at least one guide groove 191, which may include one guide groove 191 or multiple guide grooves 191. Figures 11-13 The example shows a case where the base 10 includes two guide ribs 101 and the lower surface of the housing 1 includes two guide grooves 191. This embodiment does not limit this, as long as each guide groove 191 is slidably connected to each guide rib 101 so that the housing 1 can slide in the base 110.

[0073] Optional, continue to refer to Figures 11-13As shown, the lower surface of the housing 1 is also provided with at least one limiting structure 192, which includes multiple serrated limiting stripes 1921; the base 10 is also provided with at least one limiting rib 102 corresponding to each limiting structure 192. In the direction perpendicular to the lower surface of the housing 1, the limiting structure 192 covers at least one limiting rib 102, so that when the housing 1 slides in the base 10, the serrated limiting stripes 1921 and each limiting rib 102 can cooperate with each other to ensure that the housing 1 has a limiting function when sliding in the base 10. Thus, the user can select the relative position of the housing 1 and the base 10 according to the needs. At the same time, it can increase the damping feel when sliding and improve the user experience.

[0074] In this configuration, each limiting structure 192 is arranged parallel to each guide groove 191. It is understandable that... Figures 11-13 This example only illustrates the case where the lower surface of the housing 1 is provided with two limiting structures 192, and each limiting structure 192 covers two limiting ribs 102. In other embodiments, the lower surface of the housing 1 may also be provided with three limiting structures 192, each limiting structure covering three limiting ribs 102. This embodiment does not limit the number of limiting structures and limiting ribs.

[0075] In an alternative embodiment, Figure 14 This is a schematic diagram of the interconnection structure of two junction boxes provided in an embodiment of the present invention, with reference to... Figure 14 As shown, the junction box may also include a connector 20, which includes a first connecting part 201 and a second connecting part 202. The first connecting part 201 and the second connecting part 202 are electrically connected. When the first connecting part 201 or the second connecting part 202 is inserted into the junction box 12, it can contact the junction conductor, so that the junction box can communicate with other modules through the connector, thereby expanding the function or structure of the junction box.
