DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-5 , an embodiment provided by the present utility model: a combined high-temperature resistant junction box, including a junction box housing body 1, a first fireproof and heat-insulating connector 2, a second fireproof and heat-insulating connector 3, a first connector plug 4 and a second connector plug 5. The first fireproof and heat-insulating connector 2 is arranged in the middle of one end of the junction box housing body 1, and the second fireproof and heat-insulating connector 3 is arranged in the middle of the other end of the junction box housing body 1. The first connector plug 4 is slidably connected to the first fireproof and heat-insulating connector 2, and the second connector plug 5 is slidably connected to the second fireproof and heat-insulating connector 3. A first fireproof and heat-insulating layer 10 is arranged inside the junction box housing body 1, and a second fireproof and heat-insulating layer 11 is arranged inside the first fireproof and heat-insulating layer 10. Sliding slots 6 are symmetrically opened on both sides of the second fireproof and heat-insulating connector 3, and side plug plates 7 are symmetrically and fixedly connected to both sides of the second fireproof and heat-insulating connector 3. A metal elastic sheet 9 is slidably inserted inside the side plug plate 7. One end of the first fireproof and heat-insulating connector 2 away from the junction box housing body 1 is symmetrically and fixedly connected with a connection plug plate 12. The first connector plug 4 is slidably inserted into the connection plug plate 12. A plug slot 8 is opened at the top of the second connector plug 5, and the side plug plate 7 is slidably connected inside the plug slot 8. A convex portion is arranged in the middle of the metal elastic sheet 9, and the convex portion is located on the side of the side plug plate 7 close to the junction box housing body 1 and inside the sliding slot 6. When the first fireproof and heat-insulating connector 2 is inserted into the second fireproof and heat-insulating connector 3, the connection plug plate 12 squeezes the metal elastic sheet 9 to stretch and deform, and the metal elastic sheet 9 is squeezed to store elastic potential energy and continuously squeezes the connection plug plate 12 to increase the damping between the connection plug plate 12 and the second fireproof and heat-insulating connector 3, improving the firmness strength. When the second connector plug 5 is inserted into the second fireproof and heat-insulating connector 3, the firmness strength can also be increased.

[0022] The first fireproof and heat-insulating connector 2 and the second fireproof and heat-insulating connector 3 are matched, and the inner diameters of the first fireproof and heat-insulating connector 2 and the second fireproof and heat-insulating connector 3 are the same. Through holes are penetrated through both ends of the junction box housing body 1, the first fireproof and heat-insulating layer 10 and the second fireproof and heat-insulating layer 11, and the through holes are matched with the first fireproof and heat-insulating connector 2 and the second fireproof and heat-insulating connector 3. When assembled, wires can be passed through the through holes, and the first fireproof and heat-insulating connector 2 and the second fireproof and heat-insulating connector 3 can provide heat insulation protection for the wires at the assembled position.

[0023] The first fireproof and heat-insulating connecting member 2 passes through the junction box housing body 1 and is fixedly connected to one end of the first fireproof and heat-insulating layer 10 close to the first connecting member plug 4. The second fireproof and heat-insulating connecting member 3 passes through the junction box housing body 1 and is fixedly connected to one end of the first fireproof and heat-insulating layer 10 far from the first fireproof and heat-insulating connecting member 2. The integrated design of the first fireproof and heat-insulating connecting member 2, the second fireproof and heat-insulating connecting member 3 and the first fireproof and heat-insulating layer 10 can improve the strength of the combined installation.

[0024] Working principle: During use, first take out the corresponding number of junction box housing bodies 1 according to the installation needs for installation. When combined installation is required, the second fireproof and heat-insulating connecting member 3 on one of the junction box housing bodies 1 is inserted into the first fireproof and heat-insulating connecting member 2 on another junction box housing body 1 by an external force. At this time, the connecting plug plate 12 is inserted into the inside of the sliding slot 6, and the connecting plug plate 12 presses the metal elastic sheet 9 to stretch. The metal elastic sheet 9 is squeezed and deformed to store elastic potential energy. The convex part of the metal elastic sheet 9 closely adheres to the side wall of the connecting plug plate 12 and presses the connecting plug plate 12, so that the connection between the first fireproof and heat-insulating connecting member 2 and the second fireproof and heat-insulating connecting member 3 is more firm. Assemble all the junction box housing bodies 1 in sequence. After the assembly is completed, select whether to install the first connecting member plug 4 and the second connecting member plug 5 according to the wiring needs, or open a wire passing hole on the first connecting member plug 4 and the second connecting member plug 5, insert the first connecting member plug 4 into the first fireproof and heat-insulating connecting member 2 located on the outermost side, and insert the second connecting member plug 5 into the second fireproof and heat-insulating connecting member 3 located on the outermost side. When the external temperature is too high, the first fireproof and heat-insulating layer 10 and the second fireproof and heat-insulating layer 11 block most of the heat outside, reduce the heat transfer, and thus maintain the stability of the temperature inside the second fireproof and heat-insulating layer 11, providing protection for the wires inside the second fireproof and heat-insulating layer 11.

[0025] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
