Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to a drawer for an electrical cabinet with a positioning function. Background Technology

[0002] Electrical cabinet drawers are enclosed enclosures made of steel plates. Electrical components for incoming and outgoing circuits are installed in removable drawers, forming functional units capable of performing a specific power supply task. These functional units are typically separated from the busbars or cables by grounded metal or plastic panels to ensure electrical isolation and safety. Electrical cabinet drawers provide a stable and reliable power input to other electrical equipment, ensuring its normal operation.

[0003] Electrical cabinets typically have primary and secondary plugs at the inner and outer ends. As the drawer moves within the cabinet, the secondary plug first connects to the power supply, sending a signal to the internal electrical components. Once the signal is received correctly, the drawer is pushed inward again, connecting the primary plug and activating the electrical components inside the drawer, allowing them to begin operation. Currently, there are no positioning devices at either location. If the operator applies significant pushing force, it is easy for both the primary and secondary plugs to connect simultaneously, posing a substantial safety hazard.

[0004] It is desirable to provide a drawer for electrical cabinets with a positioning function in order to solve the above-mentioned technical problems. Utility Model Content

[0043] In this embodiment, the drawer body 1 is vertically provided with a mounting plate 7, which facilitates the installation of electrical components on the mounting plate 7.

[0044] like Figure 2 , Figure 3 and Figure 4 As shown, the positioning device 2 includes a connector and a limiting base plate 8; the connector includes a spring button 9, a movable strip 10, and a vertical strip 11; the spring button 9 is disposed on the outer wall of the outer end of the drawer body 1; one end of the movable strip 10 is connected to the spring button 9, and slides along the moving direction of the drawer body 1 under the action of the spring button 9; the movable strip 10 has an obliquely upward long groove 12, the long groove 12 passes through both sides of the movable strip 10, and one side of the vertical strip 11 has an insertion part 13, the vertical strip 11 is slidably inserted into the long groove 12 through the insertion part 13.

[0045] The limiting base plate 8 is fixed inside the electrical cabinet, such as Figure 6 As shown, the limiting base plate 8 protrudes upward to form a protruding plane, and a first insertion hole 14, a second insertion hole 15 and a third insertion hole 16 are sequentially provided on the protruding plane along the sliding direction of the drawer body 1.

[0046] When the vertical bar 11 is inserted into the first socket 14, the primary plug 3 and the second plug 4 are completely disconnected from the corresponding ports in the electrical cabinet.

[0047] When the vertical bar 11 is inserted into the second socket 15, the secondary plug-in 4 is connected to the corresponding port in the electrical cabinet, and the first plug-in 3 is disconnected.

[0048] When the vertical bar 11 is located in the third socket 16, both the primary plug-in 3 and the secondary plug-in 4 are connected to the corresponding ports in the electrical cabinet.

[0049] In this embodiment, the positioning device further includes a movement distance limiting component, which includes a moving horizontal bar 17 and a first connecting plate 18; the drawer body 1 is provided with a moving groove 19, which is horizontally arranged along a direction perpendicular to the movement direction of the drawer body 1; the moving horizontal bar 17 is slidably disposed in the moving groove 19; one end of the first connecting plate 18 is hinged to the moving horizontal bar 17, and the other end of the first connecting plate 18 is connected to the moving long bar 10; thus, the movement distance of the moving long bar 17 is limited by the horizontal movement distance of the moving horizontal bar 17, i.e., the length of the moving groove 19.

[0050] In this embodiment, the positioning device further includes an anti-deviation component, which includes a second connecting plate 20 and a third connecting plate 21.

The pin 23 passes through the arc-shaped groove 22 and is rotatably mounted on the limiting base plate 8. With this configuration, the straightness of the moving strip 10 is effectively ensured by the anti-deviation component.

[0051] In this embodiment, as Figure 5 As shown, the drawer body 1 is provided with a protective cover 24, which covers the positioning device and serves as a protective cover.

[0052] When the drawer is installed into the electrical cabinet, the vertical bar 11 on the connector is inserted into the first socket 14, and the primary plug 3 and the secondary plug 4 are both disconnected. Pressing the elastic button 9 simultaneously pushes the drawer body 1, and the moving bar 10 moves along the moving direction of the drawer body 1 until the vertical bar 11 is inserted into the second socket 15 on the limiting base plate 8. At this time, the secondary plug 4 is connected to the corresponding port in the electrical cabinet, the primary plug 3 is disconnected, and the external controller receives the signal to determine whether the electrical components in the electrical cabinet are in normal condition. When the condition is normal, the elastic button 9 is pressed again, and the moving bar 10 continues to move forward. Under the action of the long slot 12, the vertical bar 11 is lifted and moves forward until it is inserted into the third socket 16. At this time, the primary plug 3 and the secondary plug 4 are connected to the corresponding ports in the electrical cabinet, and the electrical components in the drawer body 1 begin to work.
