Description

Technical Field

[0001] This utility model belongs to the field of switch terminal technology, and specifically relates to an intelligent branch terminal. Background Technology

[0002] Intelligent distribution terminals are components used in low-voltage power distribution systems to centrally distribute main line power to multiple branch lines. They are widely used in power distribution scenarios such as industrial distribution cabinets, building distribution boxes, and data center distribution cabinets.

[0003] In existing technologies, the shunt components of intelligent branch terminals generally adopt an integrated copper busbar structure, with all wiring holes integrated on the same metal busbar. This structure requires the separate creation of molds for products with different numbers of branches and different wire diameters, resulting in high mold investment costs and long development cycles. Furthermore, it prevents flexible adjustments to the branch configuration based on on-site conditions; if a row of wiring holes is damaged, the entire shunt component must be scrapped, leading to high maintenance costs and poor versatility. Therefore, there is an urgent need for an intelligent branch terminal that allows for modular disassembly of the shunt component, flexible adaptation to different branch requirements, and eliminates the need for additional fasteners. Utility Model Content

[0004] This invention solves the problems mentioned in the background art by disassembling the current shunt assembly into multiple longitudinally arranged integrated conductive current shunt blocks and connecting them through a plug-in structure, and by using the limiting sidewall of the insulating shell to achieve axial anti-disengagement.

[0005] The technical solution of this utility model is implemented as follows: an intelligent branch terminal includes an insulating shell, and further includes: The current shunt assembly is installed inside the insulating housing. The current shunt assembly includes at least two integral conductive current shunt blocks arranged longitudinally. The exposed surface of the current shunt assembly forms a stepped structure. The two adjacent conductive shunt blocks are detachably connected by a plug-in structure. The plug-in structure includes a plug-in groove formed at the bottom of the upper conductive shunt block and a plug-in boss integrally formed at the top of the lower conductive shunt block. The opening of the plug-in groove faces the limiting sidewall of the insulating shell so that the end of the plug-in boss is exposed on the limiting sidewall after the plug-in is completed. Wherein, after the shunt assembly is installed into the insulating housing, the limiting sidewall blocks the exposed end of the plug-in boss to restrict its axial disengagement.

[0006] The present invention is further configured such that the insertion groove is a dovetail-shaped groove, and the insertion boss is a dovetail-shaped boss adapted to the dovetail-shaped groove.

[0007] The present invention is further configured such that a stepped support platform is integrally formed inside the insulating shell, and the stepped surface of the stepped support platform is in contact with the non-exposed stepped surface of the diversion component.

[0008] The present invention is further configured such that the current shunt component is composed of a first conductive current shunt block, a second conductive current shunt block and a third conductive current shunt block arranged sequentially from top to bottom.

[0009] The present invention is further configured such that each of the conductive shunt blocks is provided with a plurality of parallel wire insertion holes and a screw crimping hole that is perpendicularly connected to the wire insertion holes.

[0010] The present invention is further configured such that a flip-top protective cover made of transparent material is hinged to the top of the insulating shell.

[0011] By adopting the above technical solution, the beneficial effects that this utility model can achieve are: 1. By disassembling the current shunt assembly into multiple integrated conductive current shunt blocks and using a plug-in structure for detachable connection, flexible combination and individual replacement of the current shunt specifications are achieved, improving the product's versatility and production economy.

[0012] 2. Axial anti-detachment is achieved by opening the insertion groove toward the limiting side wall of the insulating housing and using the side wall to block the end of the boss, eliminating the need for additional fixing structures and improving assembly efficiency and structural reliability.

[0013] 3. By forming a stepped structure on the exposed surface of the shunt component and fitting it with the stepped support platform inside the housing, the wiring operation space and heat dissipation path are optimized, improving the product's ease of use and operational stability.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-4 : Example 1:

[0017] This embodiment provides an intelligent branch terminal, including an insulating housing 1, and further including: The current shunt assembly 2 is installed inside the insulating housing 1. The current shunt assembly 2 includes at least two integrated conductive current shunt blocks arranged sequentially along the longitudinal direction. The exposed surface of the current shunt assembly 2 forms a stepped structure as a whole. The two adjacent conductive shunt blocks are detachably connected by a plug-in structure. The plug-in structure includes a plug-in groove 3 formed at the bottom of the upper conductive shunt block and a plug-in boss 4 integrally formed at the top of the lower conductive shunt block. The opening of the plug-in groove 3 faces the limiting sidewall 5 of the insulating housing 1 so that the end of the plug-in boss 4 is exposed outside the limiting sidewall 5 after the plug-in is completed. When the current shunt assembly 2 is installed into the insulating housing 1, the limiting sidewall 5 blocks the exposed end of the plug-in boss 4 to restrict its axial dislodgement.

[0018] The intelligent branch terminal provided in this embodiment is applied to the power distribution scenario from the main line to multiple branch lines in a low-voltage power distribution system. The intelligent branch terminal is composed of an insulating housing 1, a current shunt assembly 2, and a flip-type protective cover 9. The current shunt assembly 2 is installed in the internal cavity of the insulating housing 1, and the flip-type protective cover 9 is connected to the top of the insulating housing 1.

[0019] The insulating housing 1 is a hollow box structure injection molded from insulating engineering plastic. Its interior forms an installation cavity to accommodate the current shunt assembly 2, primarily providing insulation and structural support for the internal conductive components. One of the vertical sidewalls of the insulating housing 1 is a limiting sidewall 5, which is a flat sidewall integrally formed by the insulating housing 1, its plane perpendicular to the insertion direction of the current shunt assembly 2. An integrally formed stepped support platform 6 is formed on the inner bottom surface of the insulating housing 1. The stepped support platform 6 consists of multiple horizontal steps with progressively increasing heights, the height difference of each step matching the height difference of adjacent conductive current shunt blocks. When the stepped support platform 6 is not provided, the current shunt assembly 2 relies solely on the limiting sidewall 5 for axial limiting. When the stepped support platform 6 is provided, the non-exposed stepped surfaces of the current shunt assembly 2 are completely fitted with their corresponding step surfaces, and the lower conductive current shunt blocks simultaneously achieve auxiliary vertical and horizontal limiting through their corresponding step surfaces.

[0020] The current distribution assembly 2 is the core conductive component for power distribution. It consists of at least two integrated conductive current distribution blocks arranged longitudinally, with the exposed surfaces of all integrated conductive current distribution blocks spliced ​​together to form a stepped structure. Each integrated conductive current distribution block is a rectangular block structure integrally formed from conductive metal material and cannot be further separated. One side of each block is an exposed wiring surface, while the opposite side is a non-exposed surface that fits into the interior of the insulating housing 1. Multiple integrated conductive current distribution blocks are stacked vertically from top to bottom, with each block corresponding to a complete row of wiring positions. In this embodiment, the current distribution assembly 2 is specifically composed of a first conductive current distribution block 20, a second conductive current distribution block 21, and a third conductive current distribution block 22 arranged from top to bottom. In other embodiments, the current distribution assembly 2 can be configured with two or more integrated conductive current distribution blocks according to actual wiring requirements, with the connection method between adjacent current distribution blocks being the same as in this embodiment.

[0021] Two adjacent integrated conductive shunt blocks are detachably connected via a plug-in structure, which consists of mutually fitting plug-in grooves 3 and plug-in bosses 4. The plug-in groove 3 is formed on the bottom surface of the upper conductive shunt block, and is a horizontally extending through-slot structure with one open end and the other closed end. The plug-in boss 4 is integrally formed on the top surface of the lower conductive shunt block, and is a strip-shaped protrusion with the same cross-sectional shape as the plug-in groove 3. The open end of the plug-in groove 3 faces the limiting sidewall 5 of the insulating housing 1. After the plug-in boss 4 slides into the open end of the plug-in groove 3, it forms a sliding fit with the plug-in groove 3, achieving lateral positioning and conductive connection between adjacent conductive shunt blocks. At this time, one end of the plug-in boss 4 is exposed outside the open end of the plug-in groove 3, and this exposed end faces the limiting sidewall 5. In this embodiment, the insertion groove 3 is specifically a dovetail-shaped groove, and the insertion boss 4 is specifically a dovetail-shaped boss adapted to the dovetail-shaped groove. The dovetail-shaped cross-sectional structure can limit the relative displacement of adjacent conductive shunt blocks in the vertical direction.

[0022] Each integrated conductive shunt block has multiple parallel wire insertion holes 7 on its exposed surface. The wire insertion holes 7 are blind holes extending horizontally to accommodate the ends of the wires to be connected. Above each wire insertion hole 7, there is a corresponding screw crimping hole 8. The screw crimping hole 8 is a through hole extending vertically, and its lower end is connected to the interior of the wire insertion hole 7. The inner wall of the screw crimping hole 8 is machined with internal threads for installing a clamping screw. By tightening the clamping screw, the end of the wire inserted into the wire insertion hole 7 can be pressed and fixed onto the conductive shunt block.

[0023] The flip-top protective cover 9 is a plate-shaped structure made of transparent insulating material. One edge of the cover is hinged to the top edge of the insulating housing 1 via a pivot, allowing it to rotate around the pivot to open and close. The other edge opposite the pivot can be integrally formed with at least one elastic buckle. The top of the insulating housing 1 has a matching slot corresponding to the position of the elastic buckle. When the flip-top protective cover 9 is rotated to the closed state, the elastic buckle is engaged in the slot for detachable fixation. Pulling the buckle side edge of the flip-top protective cover 9 outward can separate the elastic buckle from the slot to open. In the closed state, the flip-top protective cover 9 covers the top opening of the insulating housing 1, preventing dust and foreign objects from entering the interior, while allowing the wiring status inside to be observed through the transparent material.

[0024] During assembly, firstly, the dovetail-shaped boss at the top of the second conductive shunt block 21 is slid into the opening end of the dovetail-shaped groove at the bottom of the first conductive shunt block 20, completing the insertion of the first conductive shunt block 20 and the second conductive shunt block 21; then, the dovetail-shaped boss at the top of the third conductive shunt block 22 is slid into the opening end of the dovetail-shaped groove at the bottom of the second conductive shunt block 21, completing the insertion assembly of the three conductive shunt blocks to form the overall shunt assembly 2. At this time, the exposed ends of all the insertion bosses 4 face the same side. Then, the assembled shunt assembly 2 is placed into the internal cavity of the insulating housing 1, so that the non-exposed stepped surface of the shunt assembly 2 is completely fitted with the stepped surfaces of the stepped support platform 6 inside the insulating housing 1. At this time, the limiting sidewall 5 of the insulating housing 1 just covers the exposed ends of all the insertion bosses 4, restricting the sliding and disengagement of the insertion bosses 4 along the insertion direction, without the need for additional fixing structures such as pins and buckles. Finally, rotate the flip-top protective cover 9 around the pivot to close it, completing the overall assembly.

[0025] In use, open the flip-top protective cover 9, insert the main cable into the wire insertion hole 7 of the bottom conductive shunt block, and tighten the corresponding clamping screws to secure it; then insert each branch wire into the corresponding wire insertion hole 7 of the conductive shunt block according to its wire diameter, and tighten the corresponding clamping screws to secure it. When it is necessary to adjust the number of branch wires or replace a damaged conductive shunt block, simply open the flip-top protective cover 9, remove the shunt assembly 2 from the insulating housing 1, and slide it apart along the insertion direction to replace or reassemble the corresponding conductive shunt block.

[0026] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
