Description

Technical Field

[0001] The utility model relates to the field of power distribution cabinets, and in particular to a power distribution wire row and a power distribution cabinet. Background Art

[0002] The distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), and metering cabinet (box). It is the final equipment of the power distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in places where the load is relatively dispersed and there are fewer circuits; the motor control center is used in places where the load is concentrated and there are more circuits. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load.

[0003] Corresponding distribution cables are usually distributed inside the power distribution cabinet for the distribution of wires. At present, most traditional distribution cables place the terminals of the wires on the plate and directly tighten them with bolts. This operation method has the following defects in actual application:

[0004] Since bolts are used for direct fixing, the bolts need to be aligned with the through holes on the wire terminals, one hand is used to support the wire terminals to fit on the plate, and the other hand needs to take the bolts and tighten them with tightening tools, which makes the operation more cumbersome. Therefore, we have made improvements on this and proposed a distribution line bus and distribution cabinet. Utility Model Content

[0005] The utility model aims to provide a power distribution wire row and a power distribution cabinet, which solves the problem that the existing power distribution wire row and the power distribution cabinet are complicated to operate during use.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] A distribution line bar and a distribution cabinet include a plate body, a locking boss is fixed on the surface of the plate body, a wiring terminal is clamped on the plate body through the locking boss, a guide column is provided below the locking boss, and a locking structure for pressing and locking the wiring terminal is slidably provided on the surface of the guide column.

[0008] As a preferred technical solution of the present application, the locking structure includes a sliding plate slidably arranged on the surface of the guide column and a guide ring connected to the surface of the sliding plate;

[0009] A clamping ring is coaxially fixed on one side of the guide ring, and a clamping groove for the locking boss to pass through is formed inside the clamping ring and the guide ring.

[0010] As a preferred technical solution of the present application, the locking structure also includes a locking bolt arranged on the other side of the guide ring, and a locking hole for the locking bolt to pass through is opened on the surface of the locking boss.

[0011] As a preferred technical solution of the present application, a locking ring coaxially arranged with the locking hole is fixed on the back side of the plate body, and one end of the locking bolt is threadedly penetrated into the locking ring through the locking hole to form a compression lock for the terminal.

[0012] As a preferred technical solution of the present application, the guide column includes a column fixed to one side of the plate body and a limit plate connected to the end of the column;

[0013] Wherein, limiting strips are distributed on both sides of the upper surface of the column, and the sliding plate can slide along the length direction of the column through the action of the limiting strips.

[0014] A power distribution cabinet includes a distribution line row and a cabinet body, wherein the plate body is arranged on the top wall and the bottom wall inside the cabinet body, and an electrical component assembly is arranged in the middle of the cabinet body. The wires on the electrical component assembly are connected to the plate body through terminal blocks, and the plate body is connected to the outside through the wires.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] In the scheme of this application:

[0017] 1. Through the provided locking boss, the terminal to be fastened can be directly sleeved on the locking boss to form a preliminary positioning, and the guide ring is directly pushed to make the clamping ring on it realize the clamping of the terminal, and the locking bolt on it will also move synchronously, so as to facilitate direct rotation locking. Compared with the traditional operation method, there is no need to manually align the terminal when tightening the bolt, and there is no need to take the bolt additionally to quickly perform the tightening operation;

[0018] 2. By setting up the guide column, when the terminal block is disassembled, the locking bolt after disassembly is affected by the guide column and is not easily lost. When it needs to be fixed later, the guide ring can be directly pushed into the surface of the column to achieve automatic locking, which further facilitates the subsequent maintenance and use of the distribution line.

[0035] The locking structure 2 includes a sliding plate 21 slidably disposed on the surface of the guide column 13 and a guide ring 22 connected to the surface of the sliding plate 21;

[0036] A clamping ring 23 is coaxially fixed to one side of the guide ring 22, and a clamping groove 24 is formed inside the clamping ring 23 and the guide ring 22 for the locking boss 11 to pass through;

[0037] The locking structure 2 further includes a locking bolt 25 disposed on the other side of the guide ring 22, and a locking hole 26 for the locking bolt 25 to pass through is formed on the surface of the locking boss 11;

[0038] A locking ring 27 coaxially arranged with the locking hole 26 is fixed on the back of the plate body 1, and one end of the locking bolt 25 is threadedly inserted into the locking ring 27 through the locking hole 26 to form a compression lock on the wiring terminal 12;

[0039] In the actual wire arrangement process, the wiring terminal 12 is buckled on the corresponding locking boss 11 to achieve the preliminary positioning of the wiring terminal 12, and then the sliding plate 21 is pushed on the surface of the guide column 13 so that the clamping ring 23 on it passes through the locking boss 11 and is close to the surface of the wiring terminal 12, and then the locking bolt 25 is directly tightened so that one end thereof forms a threaded fit with the locking ring 27 on the back, so that the clamping ring 23 can form a resistance to the wiring terminal 12 and tighten it;
