[0020] Specifically, the branching assembly includes: a first conductor 12, a plurality of positive sub-output wires 13, a positive total input wire 14, a second conductor 15, a plurality of negative sub-output wires 16 and a negative total input wire 17. Among them:

[0021] The first conductor 12 is formed with: a first front connection step 121, a first connection recess 122 and a first rear connection step 123. The first front connection step 121 and the first rear connection step 123 are respectively located at the front and rear sides of the first connection recess 122. The first connection recess 122 is formed with a first through groove 124 on the side wall below the first front connection step 121 for the end of another part of the positive output wire 13 to pass through and connect to the first connection recess 122. The first front connection step 121 is formed with a threaded hole 20 along the straight line position, the first connection recess 122 is formed with a straight line position and the first rear connection step 123.

That is to say, during installation, the wire noses 18 of some positive output wires 13 are connected to the threaded holes 20 of the first front connection step 121 along a straight line, and the other part of the positive output wires 13 are passed through the first through slots 124 and connected to the threaded holes 20 of the first connection recesses 122 along a straight line, and the positive total output wire is connected to the threaded hole 20 of the first rear connection step 123. Through such a structural design, the positive output wires 13 with wire noses 18 and the positive total input wire 14 can be quickly installed and removed separately, and the installation of the two layers of positive output wires 13 does not interfere with each other.

[0022] The second conductor 15 is formed with: a second front connection step 151, a second connection recess 152 and a second rear connection step 153.

That is to say, during installation, the wire noses 18 of some negative sub-output wires 16 are connected to the threaded holes 20 of the second front connection step 151 along a straight line, and the other part of the negative sub-output wires 16 pass through the second through slots 154 and are connected to the threaded holes 20 of the second connection recesses 152 along a straight line, and the negative total output wire is connected to the threaded hole 20 of the second rear connection step 153. Through such a structural design, the negative sub-output wires 16 with wire noses 18 and the negative total input wire 17 can be quickly installed and removed separately, and the installation of the two layers of negative sub-output wires 16 does not interfere with each other.

[0023] Further, a first upper pressing plate 1113 is provided in the first installation chamber 111 for pressing the first conductor 12 from above, and a first front side plate 1114 and a first rear side plate 1115 are provided on the front and rear sides of the first installation chamber 111, respectively. The first front side plate 1114 is used to define the first conductor 12 from the front side of the first conductor 12, and the first rear side plate 1115 is used to define the installation position of the first conductor 12 from the rear side of the first conductor 12. A second upper pressing plate 1123 is provided in the second installation chamber 112 for pressing the second conductor 15 from above, and a second front side plate 1124 and a second rear side plate 1125 are provided on the front and rear sides of the second installation chamber 112, respectively. The second front side plate 1124 is used to define the second conductor 15 from the front side of the second conductor 15, and the second rear side plate 1125 is used to define the installation position of the second conductor 15 from the rear side of the second conductor 15. Such an installation structure enables the installation housing 11 to effectively limit the position of the branching assembly, thereby ensuring the installation accuracy of the branching assembly.

[0024] Therefore, the above-mentioned junction box 10 that can be installed with wire noses is designed through the structure of the installation shell 11, the first conductor 12 and the second conductor 15, so that the installation shell 11 can efficiently install the output wires and input wires with wire noses, while ensuring the stability of the wire connection structure and avoiding wire crushing, and can effectively improve the wire installation efficiency in the junction box.

[0025] As a specific implementation, the first upper pressing plate 1113 is detachably installed in the first installation bin, and one side thereof abuts against the side wall of the first rear connection step 123, and the lower end of the first upper pressing plate 1113 abuts against the concave surface of the first connection recess 122. The second upper pressing plate 1123 is detachably installed in the second installation bin, and one side thereof abuts against the side wall of the second rear connection step 153, and the lower end of the second upper pressing plate 1123 abuts against the concave surface of the second connection recess 152. In this way, the branching assembly can be further compressed, the installation accuracy of the branching assembly can be ensured, and the line can be prevented from shaking. At the same time, the detachable installation structure is used to facilitate the assembly of the first conductor 12 and the second conductor 15, and the installation efficiency is higher.

[0026] Specifically, buckles are formed at both ends of the first upper pressing plate 1113 and the second upper pressing plate 1123, and the side wall of the first installation chamber is formed with a first clamping groove 1111 for matching the buckles at both ends of the first upper pressing plate to clamp and install the first upper pressing plate, and the side wall of the second installation chamber is formed with a second clamping groove 1121 for matching the buckles at both ends of the second upper pressing plate to clamp and install the second upper pressing plate. The installation operation is simpler and faster by assembling through the installation structure of the buckles and the clamping grooves.

[0027] Furthermore, the first front side panel 1114 and the second front side panel 1124 are also installed in the first installation compartment 111 and the second installation compartment 112 respectively by adopting a card-detachable structure, so as to improve the portability of the disassembly, assembly and maintenance of the overall junction box. Specifically, buckles are formed at both ends of the first front side panel 1114 and the second front side panel 1124, and the side wall of the first installation compartment is formed with a first front side slot 1112 for matching the buckles at both ends of the first front side panel 1114 to snap-fit ​​and install the first front side panel 1114, and the side wall of the second installation compartment is formed with a second front side slot 1122 for matching the buckles at both ends of the second front side panel 1124 to snap-fit ​​and install the second front side panel 1124.

[0028] As a specific embodiment, the first front side plate 1114 is formed with an L-shaped contact surface, and the two mutually perpendicular L-shaped surfaces of the first front side plate 1114 respectively contact the front side surface and the bottom side surface of the first front connecting step 121. The second front side plate 1124 is also formed with an L-shaped contact surface, and the two mutually perpendicular L-shaped surfaces of the second front side plate 1124 respectively contact the front side surface and the bottom side surface of the second front connecting step 151. The L-shaped contact surface can not only effectively limit the first conductor 12 and the second conductor 15, but also effectively support the first conductor 12 and the second conductor 15. More importantly, by setting the L-shaped contact surface, the front connecting steps of the first conductor 12 and the second conductor 15 and the sub-output wires arranged below can be isolated, thereby ensuring that the two layers of sub-output wires do not interfere with each other, and the disassembly and assembly safety is higher.

[0029] As a specific implementation, the upper end surface of the first rear side plate 1115 and the upper end surface of the first rear connection step 123 are located in the same horizontal plane, and the upper end surface of the second rear side plate 1125 and the upper end surface of the second rear connection step 153 are also located in the same horizontal plane. In this way, the first rear side plate 1115 and the second rear side plate 1125 can be used to provide auxiliary support for the wire lugs of the total input wire, and the connection structure is more stable. At the same time, the side surfaces of the first rear connection step 123 and the second rear connection step 153 can be prevented from being exposed, and the safety of the installation operation is also higher.

[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the above embodiments do not limit the utility model in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the utility model.
