Description

Technical Field

[0001] This utility model relates to the field of junction box technology, and specifically to a junction box. Background Technology

[0002] Energy storage containers are an integrated and modular energy storage solution. By integrating core equipment such as lithium battery packs, battery management systems (BMS), energy storage converters (PCS), and temperature control systems into standardized containers, they achieve efficient storage and flexible scheduling of electrical energy, adapting to diverse scenarios such as new energy power plants, industrial parks, and remote areas.

[0003] Traditional combustible gas detectors are installed directly inside the energy storage container. Because they do not have a self-locking function, they are difficult to effectively protect and lock when an anomaly is detected or the equipment itself malfunctions. In addition, their maintenance relies on manual on-site zeroing at regular intervals, which makes the layout of fire alarm and ventilation system pipelines and equipment linkage logic inside the energy storage container messy and disordered, further affecting the overall safety management efficiency.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0028] like Figures 1-5 As shown, in one embodiment, a junction box includes: a box body 1; wherein, inside the box body 1, a detector module 3, a terminal block 4, and a relay module 5 are respectively installed via a back support plate 2. The detector module 3 is electrically connected to the terminal block 4 and the relay module 5 via wire harnesses. All connecting wire harnesses are eventually converged and led out of the junction box, ensuring the safety and reliability of circuit transmission.

[0029] For example, the top of the box body 1 is detachably fitted with a cover 6, which facilitates daily inspection and maintenance of the internal modules and provides effective dust and moisture protection for the internal components; the side of the box body 1 is provided with a lead wire hole 11 for external wire harnesses to enter and exit, avoiding the mess caused by random arrangement of wire harnesses.

[0030] Please continue reading. Figures 1-5 The back support plate 2 has multiple sets of mounting holes 21 at its end, which are used not only to firmly fix the back support plate 2 to the box body 1, but also to provide connection points for the installation of other functional modules.

[0031] The back support plate 2 is detachably connected to the box body 1 through a set of mounting holes 21 on the edge and screws or other connectors, which ensures the connection strength and facilitates disassembly and adjustment in the future.

[0032] Furthermore, the first mounting plate 7 is detachably mounted on the top of the back support plate 2 through a set of mounting holes 21 in the middle and with screws and other connecting parts, and the detector module 3 is detachably mounted on the first mounting plate 7;

[0033] Specifically, the first mounting plate 7 includes a first main body 71, and the edge of the first main body 71 is provided with a first bent part 72, which can fit with the edge of the detector module 3 to help limit the main body and wiring terminal parts, effectively preventing shaking and displacement during transportation or use.

[0034] Correspondingly, a second mounting plate 8 can be detachably mounted on the bottom of the back support plate 2 through a set of mounting holes 21 in the middle and with screws and other connecting parts. Terminal blocks 4 and relay modules 5 can be detachably mounted on the second mounting plate 8.

[0035] Specifically, the second mounting plate 8 includes a second main body 81, and a second bent part 82 is provided along the edge of the second main body 81, which can fit with the edge of the terminal block 4 and the relay module 5 to help limit the main body and wiring terminal parts, effectively preventing shaking and displacement during transportation or use.

[0036] Working principle: First, the back support plate 2 is firmly installed in the preset position inside the box 1 using screws and other connectors to form a basic installation frame; then, according to the assembly sequence, different modules are respectively installed on the first mounting plate 7 and the second mounting plate 8 of the back support plate 2 using screws and other connectors to complete the positioning and fixing of each module; then, the internal wiring is carried out and neatly stored inside the box 1 to avoid wire harness tangling; all connecting wire harnesses between modules and external connecting wire harnesses are uniformly led out through the lead hole 11 on the side of the box 1.

[0037] Through the above technical solution, this application achieves compact installation of multiple modules within the space of the box 1, which greatly saves installation space. At the same time, the integrated layout of each module and the orderly routing of the wiring harness effectively solve the problem of chaotic layout of fire protection and ventilation system pipelines and electrical components inside the energy storage container under the traditional decentralized installation mode, and improve the safety and maintainability of the overall system.

[0038] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
