Example 1

As shown in fig. 1 to 3, the present embodiment discloses a cabinet, which includes a casing 1; as in the conventional cabinet, a cabinet door (not shown) is provided on the cabinet 1, and a plurality of partitions for installing various electric or electronic devices are partitioned inside the cabinet 1, and a heat dissipation element and the like are also provided. In addition, a plurality of threading holes 11 are formed in the cabinet wall of the machine shell 1, and the threading holes 11 can be located on two side walls of the machine shell 1 and are used for leading in and leading out wires. Correspondingly, the cabinet wall of the casing 1 is also provided with a dustproof device 2, and the position of the dustproof device 2 corresponds to the position of the threading hole 11.

As shown in fig. 2 and 3, compared with the conventional cabinet, the present embodiment is improved by the improvement of the dustproof device 2, and the dustproof device 2 of the present embodiment includes an outer protective plate 8 disposed on the outer wall of the enclosure 1. Specifically, the outer guard 8 is provided with outer guard through holes 9, and the number of the outer guard through holes 9 is the same as that of the threading holes 11.

In addition, the upper and lower ends of the outer shield 8 are bent toward one side of the outer wall of the casing 1, so that a buffer chamber 10 is formed between the outer shield 8 and the outer wall of the casing 1. Meanwhile, the two ends of the outer guard plate 8 are provided with end plates for plugging the buffer cavity 10, and the threading hole 11 and the outer guard plate perforation hole 9 are communicated with the buffer cavity 10.

The outer guard plate 8 in this embodiment may be fixed to the casing 1 by screws, and on this basis, the diameter of the outer guard plate through hole 9 is the same as the diameter of the threading hole 11, and the outer guard plate through hole 9 and the threading hole 11 are disposed opposite to each other, that is, the outer guard plate through hole 9 and the threading hole 11 are located on the same horizontal plane, so that the connection cable 3 conveniently passes through the outer guard plate through hole 9 and the threading hole 11.

In actual setting, the diameters of the outer sheath through hole 9 and the threading hole 11 are both larger than the joint of the connecting cable 3. Due to the arrangement of the buffer cavity 10, after dust enters the buffer cavity 10 from a gap between the connection cable 3 and the hole wall of the outer guard plate through hole 9, most of the dust sinks to the bottom of the buffer cavity 10, so that the probability of the dust entering the inside of the machine shell 1 can be reduced.

Example 2

The present embodiment is substantially the same as embodiment 1, and the difference is that the outer protective plate 8 in the present embodiment is not fixed on the casing 1 by screws, and the specific installation manner is as follows: the outer wall of the casing 1 is provided with two horizontal sliding rails 12, the upper end and the lower end of the outer guard plate 8 are both provided with sliding parts 13 clamped into the two horizontal sliding rails 12, and the sliding parts 13 can slide on the horizontal sliding rails 12. That is, the outer shield 8 of the present embodiment is mounted on the casing 1 through the horizontal sliding rail 12 and the sliding part 13, so that the outer shield 8 can be conveniently detached.

Meanwhile, the diameter of the outer sheath through hole 9 of the embodiment is the same as the diameter of the threading hole 11, the outer sheath through hole 9 and the threading hole 11 are located on the same vertical plane, and the outer sheath through hole 9 is located below the threading hole 11. The dust sinks due to its own weight, and the probability of the dust entering the inside of the cabinet 1 can be further reduced by disposing the wire passing hole 11 above the outer shield penetration hole 9. On the basis of the structure, when threading, the connecting cable 3 firstly passes through the outer guard plate through hole 9 and the threading hole 11 and then the outer guard plate 8 is installed on the machine shell 1, so that normal threading cannot be influenced.

Example 3

As shown in fig. 4 to 6, in this embodiment, on the basis of

embodiments

1 and 2, the dust-proof device 2 further includes two vertical slide rails 15 disposed on the inner wall of the housing 1, and a shielding assembly slidably disposed on the two vertical slide rails 15; the threading hole 11 is located between two vertical slide rails 15.

In particular, the shutter assembly comprises an upper shutter 17 and a lower shutter 19, which are arranged on two vertical sliding rails 15. This lower extreme of going up shielding plate 17 is provided with bayonet socket 7, and lower shielding plate 19's upper end is provided with bayonet socket 6 down, and when last shielding plate 17 supported each other with lower shielding plate 19, last bayonet socket 7 can form a circle with lower bayonet socket 6 to can the centre gripping pass through the connection cable 3 of through wires hole 11, because the diameter of connection cable 3 is less than the diameter of through wires hole 11, upward shielding plate 17 and lower shielding plate 19 can shelter from the gap between connection cable 3 and the through wires hole 11 this moment.

In addition, the back sides of the upper shielding plate 17 and the lower shielding plate 19 are protruded backwards, so that the back sides of the upper shielding plate 17 and the lower shielding plate 19 are attached to the inner wall of the casing 1, and the gap between the connecting cable 3 and the threading hole 11 can be blocked more tightly.

The two vertical sliding rails 15 are provided with moving grooves 5, and the moving grooves 5 are provided with locking bolts 4 for locking the lower shielding plate 19.

When the cable connector is used, the upper shielding plate 17 is lifted upwards, the connecting cable 3 passes through the outer protective plate through hole 9 and the threading hole 11, the upper shielding plate 17 is loosened, and the upper shielding plate 17 falls due to gravity and is clamped on the upper half part of the connecting cable 3. The lower shielding plate 19 is lifted upwards, the lower half part of the connecting cable 3 is clamped in the lower bayonet 6 of the lower shielding plate 19, the position of the locking bolt 4 is moved at the moment, the locking bolt 4 is screwed down to fix the lower shielding plate 19, and the upper shielding plate 17 and the lower shielding plate 19 can block the gap between the connecting cable 3 and the threading hole 11.

When the threading hole 11 does not penetrate the connecting cable 3, the upper shielding plate 17 falls down due to self gravity to block the threading hole 11, and dust cannot enter the casing 1.

It should be noted that all of the features disclosed in this specification, or all of the steps in any method or process so disclosed, may be combined in any combination, except for mutually exclusive features and/or steps.

In addition, the above embodiments are exemplary, and those skilled in the art can devise various solutions in light of the disclosure, which are all within the scope of the disclosure and fall within the scope of the invention. It should be understood by those skilled in the art that the present specification and drawings are illustrative only and are not limiting upon the claims. The scope of the invention is defined by the claims and their equivalents.
