Description

Technical Field

[0001] The utility model belongs to the technical field of power distribution cabinets, and in particular relates to a power distribution cabinet with an inlet and outlet line sealing structure. Background Art

[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. 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. This level of equipment should provide protection, monitoring and control for the load.

[0003] When the existing distribution cabinet is in use, the wires generally enter through the threading holes directly opened on the surface of the distribution cabinet body. However, the threading holes are generally large, and the wires cannot form a sealed connection with the threading holes. Animals such as mice or birds may pass through the empty space. When these animals enter the distribution cabinet, they may gnaw on the wires in the box, causing damage or even destruction of the device. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a power distribution cabinet with an inlet and outlet line sealing structure.

[0005] The technical solution adopted by the utility model is as follows:

The box body 1 is used to install electrical components and arrange wires that form a controllable electrical connection with the electrical components.

[0028] The box body 1 is square and has a total of six end faces. The end face designated to be installed with the box door 11 is the front end face, the end face corresponding to the front end face is the rear end face, the end face located between the front end face and the rear end face and fitted with the top end thereof is the upper end face, the end face located between the front end face and the rear end face and fitted with the bottom end thereof is the lower end face, the end face located between the front end face and the rear end face and fitted with the left side wall thereof is the left side face, and the end face located between the front end face and the rear end face and fitted with the right side wall thereof is the right side face; the threading hole for passing the wire can be located on any end face except the front end face, but in order to improve the sealing degree of the device, it should be preferably set on the lower end face.

[0029] Combination Figure 2 The sealing structure 12 has two detachable wire clamps 121, and the inner wall of each wire clamp 121 is provided with a wire groove 122, which is semicircular. When the broken surfaces of the two wire clamps 121 are fitted together, the two wire grooves 122 form a circle for the wire to pass through; a first fixing structure 123 is provided at one end of the wire clamp 121, and a second fixing structure 124 is provided at the other end of the wire clamp 121 and corresponding to the first fixing structure 123, and the first fixing structure 123 and the second fixing structure 124 respectively fix the two ends of the wire clamp 121; a first threading hole 125 for passing the wire is opened through the surface of the first fixing structure 123, and a second threading hole 126 for passing the wire is opened through the surface of the second fixing structure 124.

[0030] When in use, the wire enters the inner cavity 2 through the threading hole, and the separated wire clamps 121 are respectively arranged on both sides of the wire located at the threading hole, and then the wire clamp 121 is fitted. After the wire is sealed and fixed by the wire clamp 121, the first fixing structure 123 or the second fixing structure 124 passes through the wire clamp 121, and then passes through the second fixing structure 124 or the first fixing structure 123, and then the first fixing structure 123 and the second fixing structure 124 are respectively locked on the surface of the wire clamp 121, and the wire clamp 121 is locked in a sealed state at the threading hole; at this time, the locked wire is connected to the electrical components in the inner cavity 2.

[0031] The fixing methods of the first fixing structure 123 and the second fixing structure 124 to the wire clamp 121 include but are not limited to concave-convex snap connection, threaded connection and key connection.

[0032] In order to further improve the sealing performance of the device wiring and delay the damage to electrical components caused by fire due to line aging, an isolation plate 6 is detachably arranged in the inner cavity 2. The isolation plate 6 isolates the inner cavity 2 into two cavities, one of which is a wiring cavity 4 for wiring, and the other is an electrical cavity for installing electrical components; a wire outlet hole 7 for the wire to pass through is opened on the surface of the isolation plate 6.

[0033] When in use, the wires in the inner cavity 2 pass through the wiring cavity 4 through the wire outlet hole 7 and enter the electrical cavity. The wire outlet hole 7 can be located at any position of the isolation plate 6, but in order to improve the overall sealing performance of the isolation plate 6, it is best to set the wire outlet hole 7 at the upper edge or lower edge of the isolation plate 6.

The fireproof board 3 fits the inner wall of the wiring cavity 4. At the same time, the fireproof board 3 can be integrally formed or spliced.

[0036] In order to improve the sealing performance of the device, a sealing strip 112 is provided at the connection between the door 11 and the box body 1, and a sealing groove 5 for accommodating the sealing strip 112 is provided at the position where the sealing strip 112 contacts the door 11. When in use, the user uses the hinge between the door 11 and the box body 1, and drives the door 11 to rotate on the surface of the box body 1 through the handle 111 installed on the surface of the door 11, so as to drive the sealing strip 112 to separate from the sealing groove 5, and the door 11 is opened; Figure 3 When closing, the user drives the door 11 close to the box body 1 through the hinge until the sealing strip 112 on the inner wall of the door 11 enters the sealing groove 5 on the surface of the box body 1, and the door 11 is closed on the box body 1 in a sealed state.

[0037] In order to improve the safety performance of the device, a lock body can be provided on the surface of the box door 11 , and the lock body can lock the box door 11 on the box body 1 .
