Description

Technical Field

[0001] This utility model belongs to the field of energy storage system application equipment, and specifically relates to a fence through-wall terminal for energy storage systems. Background Technology

[0002] In modern energy storage systems, fence through-wall terminals are connectors used for power transmission or signal transmission. However, existing fence through-wall terminals on the market generally have some shortcomings. First, most existing products are developed separately for each number of interfaces (e.g., single-channel, dual-channel, triple-channel, quad-channel, etc.), which necessitates designing and manufacturing different molds for each interface, resulting in high production costs. Second, although some products employ a modular design, the lack of effective connections between multiple components often leads to products with large dimensions, making them prone to warping and deformation, affecting performance and reliability.

[0003] Furthermore, many existing products' U-shaped copper connectors have internal threads on the through holes at both ends. Although this allows for connection after tightening, it is prone to stripping, leading to a weak connection. This not only increases resistance but may also cause temperature increases, posing potential safety hazards. In addition, existing products generally lack effective safety protection devices to fully ensure user safety during operation. Utility Model Content

[0004] The purpose of this invention is to provide a fence-through terminal for energy storage systems, which improves overall performance, reduces production and usage costs, and enhances safety and reliability. Furthermore, the terminal design can adapt to application scenarios with varying numbers of interfaces, ensuring convenient and efficient construction.

[0005] To achieve the above-mentioned technical objectives, the technical solution of this utility model is as follows:

[0006] A fence-through terminal for an energy storage system includes a left-end fixing frame, a right-end fixing frame, and at least one intermediate fixing frame. The left-end fixing frame, intermediate fixing frame, and right-end fixing frame are arranged sequentially. A conductive component receiving cavity is formed between the left-end fixing frame and its adjacent intermediate fixing frame, between the right-end fixing frame and its adjacent intermediate fixing frame, and between adjacent intermediate fixing frames (if any). A conductive component is disposed in the conductive component receiving cavity. The conductive component includes a support column. An upper bolt and an upper nut are disposed at the top of the support column. The upper nut is located in an upper nut limiting hole at the top of the support column. A lower bolt and a lower nut are disposed at the bottom of the support column. The lower nut is located in a lower nut limiting hole at the bottom of the support column. The upper bolt and the lower bolt are connected by a conductive plate. The conductive plate has an upper bolt hole through which the upper bolt passes and a lower bolt hole through which the lower bolt passes.

[0007] The left end fixing frame, the middle fixing frame and the right end fixing frame are all provided with screw holes, and the screws pass through the screw holes to connect the left end fixing frame, the middle fixing frame and the right end fixing frame together.

[0008] The left end fixing frame or the middle fixing frame consists of a partition and two limiting blocks on the partition, with a spacing between the two limiting blocks for accommodating conductive components.

[0009] To prevent misalignment and deformation during assembly and to ensure effective connection of the product, multiple positioning pins are provided between the left end fixing frame and its adjacent intermediate fixing frame, between the right end fixing frame and its adjacent intermediate fixing frame, and between adjacent fixing frames (if any).

[0010] It also includes a cover plate, the bottom of which has a front snap fastener and a rear snap fastener. The left end fixing frame, the middle fixing frame and the right end fixing frame are provided with a front snap groove and a rear snap groove. The front snap fastener is snapped into the front snap groove and the rear snap fastener is snapped into the rear snap groove.

[0011] The front snap fastener is formed by bending the front end of the cover plate downwards, and the rear snap fastener is formed by bending the rear end of the cover plate downwards.

[0012] This utility model's modular design for the fence through-wall terminal (including the ability to add or remove left, middle, and right fixing brackets) supports flexible adaptation from single to multi-channel configurations, eliminating the need for developing independent molds for different numbers of interfaces and significantly reducing production costs. Secondly, the positioning pins positioned between the fixing brackets effectively prevent assembly misalignment and warping, ensuring structural stability and long-term reliability. Simultaneously, the integrated design of the upper and lower nuts, located within the upper and lower nut limiting holes of the support column respectively, ensures product reliability. Combined with the U-shaped conductive sheet, it prevents bolt stripping, ensuring a secure connection, reducing resistance and temperature rise risks, and eliminating safety hazards. Furthermore, the cover plate covering the top of the fixing brackets provides physical isolation and protection, enhancing operational safety and extending product lifespan.

[0020] like Figure 1-6 As shown, a fence through-wall terminal for an energy storage system includes a left-end fixing frame 1, a right-end fixing frame 3, and an intermediate fixing frame 2. The left-end fixing frame 1, the intermediate fixing frame 2, and the right-end fixing frame 3 are arranged in sequence, and a conductive component receiving cavity is formed between the left-end fixing frame 1 and the adjacent intermediate fixing frame 2, and between the right-end fixing frame 3 and the adjacent intermediate fixing frame 2.

[0021] The left-end fixing frame 1 includes a partition 11, and a front limiting block 12 and a rear limiting block 13 on the partition 11, with the front limiting block 12 and the rear limiting block 13 having a spacing for accommodating conductive components; the middle fixing frame 2 includes a partition 21, and a front limiting block 22 and a rear limiting block 23 on the partition 21, with the front limiting block 22 and the rear limiting block 23 having a spacing for accommodating conductive components; the right-end fixing frame includes a partition 31. The front limiting block 12, the rear limiting block 13, the partition 11, and the partition 21 constitute a conductive component accommodating cavity between the left-end fixing frame 1 and the middle fixing frame 2, and the front limiting block 22, the rear limiting block 23, the partition 21, and the partition 31 constitute a conductive component accommodating cavity between the right-end fixing frame 2 and the middle fixing frame 2.

[0022] To prevent misalignment and deformation during assembly and ensure effective product connection, locating pins are provided between the left end fixing frame 1 and the middle fixing frame 2, and between the right end fixing frame 3 and the middle fixing frame 2. Two locating pins are provided, each located within a locating hole. Specifically, the front limit block 12 has a locating pin 121, the rear limit block 13 has a locating pin 131, and the partition plate 21 has locating holes 122 and 132. When the left end fixing frame 1 and the middle fixing frame 2 are connected, locating pin 121 is located in locating hole 122, and locating pin 131 is located in locating hole 132. Similarly, the front limit block 22 has a locating pin 221, the rear limit block 23 has a locating pin 231, and the partition plate 31 has locating holes 222 and 232. When the right end fixing frame 3 and the middle fixing frame 2 are connected, locating pin 221 is located in locating hole 222, and locating pin 231 is located in locating hole 232. Of course, more than three locating pins can also be provided. Of course, the positioning pin can also be set on the partition, and the positioning hole can be set on the limit block.

[0023] To connect the left-end fixing bracket 1, the middle fixing bracket 2, and the right-end fixing bracket 3 together, each of these brackets is provided with screw holes. Each bracket has two screw holes. One screw hole is located on the front limit blocks 12 and 22, coaxially aligned with the positioning pins 121 and 221, and its inner diameter is smaller than the diameter of the positioning pins 121 and 221. The other screw hole is located on the rear limit blocks 13 and 23, coaxially aligned with the positioning pins 131 and 231, and its inner diameter is smaller than the diameter of the positioning pins 131 and 231. A screw 9 passes through each screw hole and is connected to a nut 91, thus connecting the left-end fixing bracket 1, the middle fixing bracket 2, and the right-end fixing bracket 3 together. Alternatively, the screw holes can be located on one side of the positioning pins.

[0024] A conductive component is housed within the cavity of the conductive component housing. The conductive component includes a support column 4. An upper bolt 51 and an upper nut 52 are located at the top of the support column 4, with the upper nut 52 positioned within an upper nut limiting hole at the top of the support column 4. A lower bolt 61 and a lower nut 62 are located at the bottom of the support column 4, with the lower nut 62 positioned within a lower nut limiting hole at the bottom of the support column. The upper bolt 51 and the lower bolt 61 are connected by a U-shaped conductive sheet 7. The conductive sheet 7 has an upper bolt hole 71 through which the upper bolt 51 passes and a lower bolt hole 72 through which the lower bolt 61 passes. The support column 4, with the upper nut 52 and the lower nut 62, is placed within the U-shaped conductive sheet 7. The upper bolt 51 passes through the upper bolt hole 71 and connects to the upper nut 52, while the lower bolt 61 passes through the lower bolt hole 72 and connects to the lower nut 62. Alternatively, anti-reverse spring washers can be provided on the upper bolt 51 and the lower bolt 61.

[0025] It also includes a cover plate 8, the bottom of which has a front latch 81 and a rear latch 82. The front latch 81 is formed by bending the front end of the cover plate 8 downwards, and the rear latch 82 is formed by bending the rear end of the cover plate 8 downwards. The left end fixing bracket 1, the middle fixing bracket 2, and the right end fixing bracket 3 are respectively provided with a front latching groove and a rear latching groove. The front latch 81 is inserted into the front latching groove, and the rear latch 82 is inserted into the rear latching groove. Figure 3 As shown, the front slot on the intermediate fixing frame 2 is like the front slot 211 on the partition 21, and also like... Figure 5 As shown, the front slot on the right end fixing bracket 3 is the front slot 311 on the partition 31, and the front locking block 81 is inserted into the front slots 211 and 311.

[0026] Of course, there can be multiple intermediate fixing frames 2 between the left fixing frame 1 and the right fixing frame 3. Multiple intermediate fixing frames 2 are arranged from left to right between the left fixing frame 1 and the right fixing frame 3, between adjacent intermediate fixing frames, between the left fixing frame 1 and its adjacent intermediate fixing frame 2, and between the right fixing frame 3 and its adjacent intermediate fixing frame 2 to form a conductive component receiving cavity.
