Description

Technical Field

[0001] The present invention relates to the technical field of electric power equipment, and in particular to an outdoor junction box. Background Art

[0002] As a key component of the outdoor electrical connection system, the outdoor junction box is widely used in many fields such as solar power generation and outdoor lighting. Its performance is directly related to the stable operation and safety of the entire outdoor electrical system.

[0003] In terms of material selection, the outer shell of the outdoor junction box is usually made of engineering plastic or metal to ensure that it has the ability to withstand complex outdoor environments, including but not limited to long-term exposure to harsh conditions such as ultraviolet radiation, rain erosion, wind and sand erosion, and large temperature fluctuations, thereby ensuring the normal working condition and service life of the internal electrical components.

[0004] From the perspective of functional realization, its core role is to achieve the effective connection of different wires or cables and complete the task of transferring and distributing electric energy. Taking the solar power generation system as an example, the electric energy generated by the solar panels is collected through cables to the junction box, where the current is integrated and then transmitted to the inverter and other subsequent equipment; in the outdoor lighting system, the main power line from the distribution box and the branch lines of each street light are connected with the help of the junction box, so as to ensure the accurate distribution of electricity and the stable operation of the street light system. At the same time, in order to ensure electrical safety, its internal design has a reliable insulation structure to effectively prevent the occurrence of short circuit and leakage of wires, and build a solid safety line for the stable operation of the outdoor electrical system.

[0005] However, although the outdoor junction box in the prior art has improved the traditional design to a certain extent, there are still many technical defects that need to be solved. It is mainly composed of a box body and a box cover. The box body is provided with a wiring cavity for cable connection. The side wall is provided with an inlet hole and an outlet hole connected to the wiring cavity. The box cover is connected to the top of the wiring cavity by a threaded method, and a groove is provided on the top edge of the wiring cavity to place a sealing strip. An operating part is provided on the top of the box cover for manual opening and closing without the need for tools, which improves the convenience of operation to a certain extent. Compared with traditional screw fixing, the threaded connection method avoids the problem of loose connection caused by rusted screws. The setting of the sealing strip also enhances the sealing of the device and effectively prevents water vapor from invading the wiring cavity. However, in actual application, the threaded connection method exposes obvious disadvantages. There is a lot of dust in the outdoor environment. When dust adheres to the thread line, it will change the friction between the threads, thereby affecting the tightness of the connection; once the thread is deformed, it is very easy to slip, which will seriously hinder the rapid disassembly and assembly of the device, greatly reduce the use efficiency, and have a significant adverse effect on the maintenance and repair of the equipment.

[0006] In addition, during the wiring operation, redundant vacant lines are often generated. In the absence of an effective arrangement and fixing mechanism, these lines can only be laid outside the wiring box, which is very easy to get tangled. Line entanglement not only destroys the overall aesthetics of the device, but more importantly, it interferes with the stability of signal transmission, increases the difficulty and time cost of line maintenance and adjustment, and reduces the reliability and maintainability of the entire electrical system.

[0032] A base plate 1, on the top of which a bottom shell 2 is fixedly mounted;

[0033] The top shell 4 is hinged to the two ends of the rear side of the bottom shell 2 through the hinge 3, and the bottom shell 2 and the top shell 4 form a wiring box;

[0034] A limiting mechanism 6, arranged on the front of the bottom shell 2 and the top shell 4, for clamping the bottom shell 2 and the top shell 4;

The limiting mechanism 6 set on the front further enhances the stability of the bottom shell 2 and the top shell 4 when they are closed, the rail frame 61 and the clamp 62 in the limiting mechanism 6 cooperate, and the limiting assembly 63 inside the rail frame 61 is clamped with the clamp 62, which ensures that the junction box will not be easily opened when used outdoors, and effectively protects the internal circuits.

[0038] At the same time, the winding mechanism 7 on the upper ends of both sides of the top shell 4 can organize and wind up the lines to avoid line entanglement, thereby improving the efficiency of line management. The semi-arc interfaces 8 at both ends of the bottom shell 2 and the top shell 4 facilitate the access and extraction of the lines, making the line connection smoother. Overall, the outdoor junction box of the embodiment of the present invention is very suitable for outdoor use, and has the advantages of high stability, convenient operation, and efficient line management.

[0039] Please refer to Figure 1 and Figure 3 The limiting mechanism 6 includes a limiting spring 631, the outer end of the limiting spring 631 is fixedly connected to a slider 632, the outer side of the slider 632 is fixedly connected to a limiting block 633, the inner side of the clamp 62 is provided with a slot 634, the outer side of the limiting block 633 is inserted into the inner side of the slot 634, and the overall front view shape of the limiting block 633 is an isosceles trapezoidal setting, the inclined surface of the limiting block 633 is set at the upper end of the outer side, the right-angled side of the limiting block 633 and the right-angled side of the slot 634 are both set at the bottom, and the limiting spring 631 in the limiting mechanism 6 provides elastic support for the entire structure.

The limit block 633 is an isosceles trapezoid as a whole and the inclined surface is set at the upper end of the outer side. This design allows the clamping member 62 to smoothly squeeze the inclined surface of the limit block 633 during the closing process, prompting the limit block 633 to move and compress the limit spring 631. When it reaches the position of the card slot 634, the limit spring 631 resets and pushes the limit block 633 into the card slot 634 to achieve precise card connection.

[0041] refer to Figure 1-Figure 4 The winding mechanism 7 includes side arms 71, which are fixedly connected to the front and rear sides of both ends of the top shell 4. The outer ends of the side arms 71 are fixedly connected to the outer shell 72, and the inner side of the outer shell 72 is fixedly connected to a torsion spring 73. A turntable 74 is welded to the inner side of the torsion spring 73. The turntable 74 is rotatably connected to the inner side of the outer shell 72.

The turntable 74 is rotatably connected to the inner side of the outer shell 72 to ensure smooth rotation. The winding shaft 75 on the inner side of the turntable 74 can neatly wind up the line to avoid disorderly lines and improve the efficiency of line management. The design of the support shaft 76 and the adjustment handle 77 is convenient for users to operate. The inner side of the adjustment handle 77 is cross-shaped, which is not only convenient for holding and turning, but also increases the convenience and accuracy of operation. The rotation of the turntable 74 can be easily controlled by adjusting the handle 77 to realize the winding and releasing of the line, making the junction box more convenient and efficient in outdoor use.

[0042] The following is an explanation of the use principle and process of the embodiment of the present invention:

[0043] By setting the limiting mechanism 6, when the embodiment of the present invention is in use, when the wiring box needs to be used, the top shell 4 and the bottom shell 2 can be closed to each other. In this process, the clamp 62 will move down with the closing of the top shell 4. When the bottom of the clamp 62 contacts the inclined surface of the limiting block 633, the clamp 62 will squeeze the limiting block 633. The squeezed limiting block 633 prompts the limiting spring 631 to contract. When the limiting block 633 moves to a position in contact with the slot 634, the limiting spring 631 will quickly reset and push the limiting block 633 to move outward. At this time, the limiting block 633 can be inserted into the inner side of the slot 634 by moving outward. The mutual insertion and limiting of the upper shell 4 and the lower shell 2 can assist in the card connection and installation of the upper shell 4 and the lower shell 2, so that the upper shell 4 and the lower shell 2 have excellent stability as a whole. In addition, if it is necessary to separate the upper shell 4 and the lower shell 2 during use, the limit block 633 can be driven to move inward by adjusting the push plate 635. During the process of the limit block 633 moving inward, the limit spring 631 will be squeezed again to shrink it. When the limit block 633 is separated from the card slot 634, the lower shell 2 and the upper shell 4 can be easily turned over. At this time, with the linkage effect of the hinge 3, the embodiment of the present invention can be opened very conveniently and quickly. It can be seen that such a design greatly improves the overall convenience of use of the embodiment of the present invention.

[0044] At the same time, by providing the winding mechanism 7, when using the embodiment of the present invention, the line can be inserted between the inner sides of the bottom shell 2 and the top shell 4. In the process of inserting the line, the turntable 74 is driven to rotate by twisting the adjusting handle 77. The torsion spring 73 is squeezed while the turntable 74 rotates, causing the torsion spring 73 to be in a tightened state, that is, the torsion spring 73 is compressed. At this time, the line is inserted between the inner sides of the two winding shafts 75. After the insertion of the shafts is completed, the adjusting handle 77 is released. At this time, the torsion spring 73 will quickly reset and drive the turntable 74 to drive the winding shaft 75 to rotate and squeeze. The rotation and squeezing of the winding shaft 75 can assist in winding the line. It can be seen that the embodiment of the present invention can be used during use. The torsion spring 73 is reset to drive the turntable 74 to rotate, and the rotation of the turntable 74 can drive the winding shaft 75 to rotate to wind up the line. When the line needs to be pulled out, it is only necessary to pull the line, which can prompt the winding shaft 75 on the turntable 74 to adaptively rotate and reset. In this way, the excess line can be pulled out from the winding shaft 75. After the line is pulled out, the torsion spring 73 is in a compressed state. After the line is released, the torsion spring 73 is reset to adaptively rewind again. It can be seen that the embodiment of the present invention has good elasticity and winding performance when used as a whole, can effectively avoid the phenomenon of line entanglement, and greatly improves the convenience of the embodiment of the present invention when used as a whole.

[0045] It can be seen from the above description that, compared with the prior art, the beneficial effects brought about by the embodiments of the present invention are: when the top shell and the bottom shell are closed, through the cooperation of the clamp and the limit block, with the help of the elastic action of the limit spring, the clamping can be quickly and stably achieved, ensuring that the junction box is firmly closed in various outdoor environments, and when it needs to be disassembled, it can be easily completed by operating the push plate, and the hinge can be cooperated to achieve rapid flipping and opening, meeting the needs of various usage scenarios, and both installation and disassembly are efficient and convenient, greatly improving the convenience of use. At the same time, the winding mechanism provides great convenience for line management, and utilizes the elastic reset characteristics of the torsion spring to adaptively wind and rotate and reset the line during the threading and drawing process, effectively avoiding the problem of line entanglement, not only making the line layout more neat and orderly, but also greatly improving the overall convenience of use, creating an efficient, stable and easy-to-operate outdoor electrical connection environment for users, which is significantly better than similar products in the prior art.

[0046] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
