Description

Technical Field

[0001] This utility model relates to the field of terminal box technology, specifically an outdoor terminal box. Background Technology

[0002] Terminal boxes are commonly installed outdoor equipment in substations, enabling electrical connections between primary and secondary systems. They typically contain a large number of terminal blocks, small air switches, secondary cables, and other auxiliary devices. Their functions include various protection, measurement and control, and anti-misoperation interlocking circuits. They are an important type of equipment in the secondary system, and the importance of their maintenance is self-evident.

[0003] To keep the wiring dry and stable, terminal boxes generally have insulation and sealing functions to prevent condensation inside the terminal box. However, water vapor can enter the terminal box from the inlet. The existing method is to apply sealant to the inlet to seal it. However, during later maintenance, the sealant must first be removed and then reapplied after maintenance, making the maintenance process quite troublesome. To solve the above technical problems, this utility model provides an outdoor terminal box. Utility Model Content

[0023] Please combine Figures 1 to 4As shown, this utility model provides an outdoor terminal box. Inside the terminal box 1, there is a movable wire plate 2 and a fixed wire plate 3. Multiple semi-circular clamping slots 4 are evenly spaced along the length of both the movable wire plate 2 and the fixed wire plate 3. These slots are located on the opposite surfaces of the movable wire plate 2 and the fixed wire plate 3. Each semi-circular clamping slot 4 has multiple through holes. The semi-circular clamping slots 4 on the movable wire plate 2 correspond one-to-one with those on the fixed wire plate 3. Multiple wire outlet holes are provided on the inner bottom surface of the terminal box 1, located directly below the semi-circular clamping slots 4. Wires pass through these outlet holes to exit the terminal box. Inside the terminal box 1, both the movable wire plate 2 and the fixed wire plate 3 have cavities for storing desiccant. Top covers 8 are detachably mounted on the tops of both the movable wire plate 2 and the fixed wire plate 3. The fixed wire plate 3 is detachably installed inside the terminal box 1. First fixing blocks 5 are fixedly mounted on both ends of the fixed wire plate 3 along its length, and second fixing blocks 13 are fixedly mounted on both ends of the movable wire plate 2 along its length. A screw 15 is rotatably mounted on one of the first fixing blocks 5, with one end of the screw 15 penetrating the interior of the second fixing block 13 and threadedly connected to it. A track plate 14 is fixedly installed on the inner bottom surface of terminal box 1, and a second fixing block 13 is slidably connected to the track plate 14. The top cover 8 is used to seal the top of the movable wire plate 2 or the fixed wire plate 3. During wiring, each wire is placed between the semi-circular clamping groove 4 on the movable wire plate 2 and the semi-circular clamping groove 4 on the fixed wire plate 3 to clamp and fix the wire. The wire finally leaves the interior of terminal box 1 through the wire outlet hole. The wire outlet hole is sealed by the movable wire plate 2 and the fixed wire plate 3, and part of the wire contacts the semi-circular clamping groove 4. Outdoors, even if humid air enters between the two semi-circular clamping grooves 4 through the wire outlet hole, the desiccant in the cavity can absorb the air. The desiccant is removed, thus keeping the interior of terminal box 1 dry. When the wire needs to be repaired, rotating one end of screw 15 allows the movable wire plate 2 to slide on the inner bottom surface of terminal box 1. At this time, the wire is not clamped and fixed, making the repair of the wire simpler and more convenient. When the desiccant in the cavity needs to be replaced, the fixed wire plate 3 is removed from the inner bottom of terminal box 1. Since the movable wire plate 2 is connected to the fixed wire plate 3 through screw 15, the movable wire plate 2 is also removed from the interior of terminal box 1. After that, the top cover 8 on the top of the movable wire plate 2 and the fixed wire plate 3 can be removed to replace the desiccant.

[0024] Furthermore, each first fixing block 5 is fixedly mounted with a mounting block 6, and each mounting block 6 is fixedly connected to the terminal box 1 by a first bolt 7;

[0025] The top cover 8 is fixedly installed with a second connecting ear 12 at both ends along its length. The movable line plate 2 and the fixed line plate 3 are fixedly installed with a first connecting ear 11 at both ends along their length. A second bolt 9 is threaded onto the second connecting ear 12, and a nut 10 is threaded onto the second bolt 9. One end of the second bolt 9 is passed through the interior of the second connecting ear 12 and the first connecting ear 11, and then threaded onto the nut 10, so that the top cover 8 can be fixedly installed on the top of the movable line plate 2 or the fixed line plate 3.

[0026] A limiting frame 16 is fixedly installed on the inner surface of the terminal box 1 and directly above the fixed wire plate 3. The limiting frame 16 has multiple arc grooves 17 at equal intervals along its length. The opening of the arc grooves 17 is smaller than the diameter of the wire. After the movable wire plate 2 is separated from the fixed wire plate 3, multiple wires are no longer restricted by the movable wire plate 2 and the fixed wire plate 3. Unrestricted wires are prone to scattering. Each wire is placed in the arc groove 17, and the multiple arc grooves 17 are used to limit each wire to prevent the wires from scattering during maintenance.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
