Description

Technical Field

[0001] The utility model relates to a protective cover for large-current outgoing terminals, belonging to the technical field of electrical equipment. Background Art

[0002] With the increasingly mature technology in the power industry, various power distribution sites pay more and more attention to safety. Taking protective isolation measures for live parts during live maintenance and repair has become a common requirement. Among them, outgoing terminals are particularly important in the entire protection system due to the large number and complex cable connection conditions. For the protection of large-current outgoing terminals, the current common practice is to install a special bellows at the cable nose to meet the requirements of safe use. However, this method requires different bellows to be selected according to the cable specifications, resulting in disadvantages such as complex installation and high production costs. Summary of the Utility Model

[0003] The purpose of the utility model is to propose a protective cover for large-current outgoing terminals to ensure safety requirements and unified installation in view of the problems existing in the prior art.

[0004] To achieve the above purpose, a protective cover for large-current outgoing terminals of the utility model includes an outgoing terminal, and a rotating bracket is provided at the upper end close to the wiring side of the outgoing terminal. The rotating bracket is connected to a protective cover that forms a rotating pair with it. Adopting a rotary opening and closing structure form, while providing comprehensive protection, it also prevents stress on the protective cover caused by cable bending. The structural standardization degree is high, and the production cost is greatly reduced.

[0005] The purpose of the utility model is further realized by the following technical solutions. A fixing hole for connecting the rotating bracket is provided on the upper edge of the outgoing terminal.

[0006] The protective cover is made of PC material, and both sides of the cover body have first connecting pieces extending outwards. First rotating holes are provided on the first connecting pieces, and the material is transparent for easy observation.

[0007] An avoidance hole is provided on the upper surface of the protective cover. The avoidance hole corresponds to the position of the fixing hole of the bracket, so that the protective cover can avoid the screws fixing the rotating bracket during rotation, and the opening angle of the protective cover can be increased.

[0008] The rotating bracket is formed by bending sheet metal into a folding surface whose length matches the upper edge of the outgoing terminal. Both sides of the folding surface have second connecting pieces perpendicular to it. The bottom of the rotating bracket gradually tapers inward on both sides to form a trapezoid. Second rotating holes matching the first rotating holes are provided on the second connecting pieces, and bracket fixing holes matching the fixing holes of the outgoing terminal are provided at the bottom of the rotating bracket.

[0009] The rotating bracket and the protective cover are connected by screws without locking, so that the protective cover has rotational freedom.

[0010] The structure of the present utility model is standard and easy to process. The rotating bracket structure endows the protective cover with a rotational degree of freedom, with the center of the rotating hole as the axis. The beneficial effects are as follows: cost is reduced, the protective cover can be opened and closed at a large angle, the protective cover does not need to be disassembled when fixing the cable, which is convenient for users to lay the cable; and after the cable is fastened, the protective cover can freely adjust the angle of the protective cover according to the fixed angle of the cable, while meeting the protection requirements, avoiding stress on the protective cover caused by the cable.

[0016] The structure of this embodiment is as shown in Figures 1-4As shown in the figure, a large-current outgoing terminal protective cover includes an outgoing terminal. A rotating bracket is provided at the upper end near the wiring side of the outgoing terminal, and the rotating bracket is connected to a protective cover that forms a rotating pair with it. The outgoing terminal 1 has a general design structure. In this embodiment, taking the Siemens 8PT cabinet type as an example, a fixing hole 1-1 is provided at the upper part of the outgoing terminal 1, which matches the bracket fixing hole 3-1 at the bottom of the rotating bracket 3, and they are connected to each other with screws for fixing the rotating bracket 3; a wiring copper bar 1-2 is provided on the front of the outgoing terminal 1 for connecting the outgoing cable. The protective cover 2 is made of transparent PC board and is processed by a cold bending process, which is simple to process. First connecting pieces are provided on both sides, and first rotating holes 2-1 are provided on the first connecting pieces, which cooperate with the second rotating holes 3-2 on both sides of the rotating bracket 3 and are connected to each other with screws without locking, enabling the protective cover to have a degree of rotational freedom; an avoidance hole 2-2 is provided on the upper surface of the protective cover, so that the protective cover 2 avoids the screws fixing the rotating bracket 3 during rotation, which can increase the opening angle of the protective cover 2. The rotating bracket 3 is bent from sheet metal material and has a folding surface whose length matches the upper edge of the outgoing terminal. Second connecting pieces perpendicular to it are provided on both sides of the folding surface, and second rotating holes 3-2 are provided on the second connecting pieces, which cooperate with the first rotating holes 2-1 on both sides of the protective cover 2 and are connected to each other with screws without locking, enabling the protective cover to have a degree of rotational freedom. The bottom sides of the rotating bracket taper inwards gradually to form a trapezoid, and a bracket fixing hole 3-1 is provided on the surface, which matches the fixing hole 1-1 at the upper part of the outgoing terminal 1 for fixing the rotating bracket 3.

[0017] When the user connects the cable, the protective cover 2 can be lifted and kept fixed by the self-gravity of the protective cover 2 without disassembling the protective cover 2.

[0018] In addition to the above embodiments, the present utility model can also have other implementation manners. All technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope required by the present utility model.
