[0002] Switch means "switch" and is a network device used for forwarding electrical (optical) signals. It can provide an exclusive electrical signal path for any two network nodes connected to the switch. The most common switch is the Ethernet switch. Other common switches include telephone voice switches, fiber optic switches, etc.

[0003] In current switches, a sealing ring is provided between the shell and the cover to ensure the sealing effect. In order to be thinner and lighter, the shell thickness is often less than 1 cm. Therefore, when the shell collides, it is easy to deform, resulting in a gap between the shell and the sealing ring, which cannot ensure a good sealing effect. Utility Model Content

[0029] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Embodiment 1:

[0031] The utility model provides a sealed communication switch. Figure 1-7 , including a switch housing 1 and a cover plate 2 covering the switch housing 1, a plug-in ring 21 is integrally provided on the cover plate 2, and the thickness of the plug-in ring 21 is set to be more than 1.5 cm, and the thickness of the plug-in ring 21 can also be set to twice the thickness of the switch housing 1, so that when the switch collides or falls during transportation, the plug-in ring 21 will not be deformed, and at this time, the top of the switch housing 1 is constrained by the clamping of the fastening ring 3, and the top of the switch housing 1 will not be deformed, so that no gap will be generated between the switch housing 1 and the sealing ring 4, and between the plug-in ring 21 and the sealing ring 4, so as to ensure a continuous sealing effect, a sealing ring 4 is sleeved on the plug-in ring 21, and a fastening ring 3 is sleeved on the top of the switch housing 1, and the fastening ring 3 squeezes the top of the switch housing 1, thereby cooperating with the plug-in ring 21 to squeeze and deform the sealing ring 4; that is, the fastening ring 3 plays the role of a clamp.

[0032] An annular notch 11 is provided at the top of the switch housing 1 , and the fastening ring 3 is sleeved on the annular notch 11 . Under the limiting effect of the annular notch 11 on the fastening ring 3 , the fastening ring 3 will not slide down accidentally, ensuring that the fastening ring 3 is located at the top of the switch housing 1 .

[0033] A first fixing block 31 is integrally provided at one end of the fastening ring 3, and a second fixing block 35 is integrally provided at the other end of the fastening ring 3. Internal threaded holes are provided at corresponding positions of the first fixing block 31 and the second fixing block 35. The first fixing block 31 and the second fixing block 35 are connected by bolts 5. When the first fixing block 31 and the second fixing block 35 are fixed by the bolts 5, the fastening ring 3 is in a stretched state, thereby maintaining tension. A fastening nut 32 is threadedly connected to the bolt 5, and is clamped by the fastening nut 32 to prevent loosening.

[0034] When used specifically:

[0035] Step 1: Install the sealing ring 4 on the plug-in ring 21, and insert the plug-in ring 21 into the top cavity of the switch housing 1;

[0036] Step 2: Sleeve the fastening ring 3 on the annular notch 11 at the top of the switch housing 1, and use the bolts 5 to fix the first fixing block 31 and the second fixing block 35 of the fastening ring 3, so that the fastening ring 3 is tightened, thereby pressing the top of the switch housing 1, so that the sealing ring 4 is deformed;

[0037] Step 3: When the switch housing 1 or the cover plate 2 collides, even if the switch housing 1 or the cover plate 2 is deformed, the plug-in ring 21 is thick and will not be deformed, so the plug-in ring 21 and the fastening ring 3 can still clamp the sealing ring 4 to ensure the sealing effect.

[0038] Embodiment 2:

[0039] See attached Figure 8-9 , which is different from the first embodiment: the cover plate 2 and the switch housing 1 are plugged in;

[0040] The bottom of the plug-in ring 21 is welded with snap-in blocks at equal distances, and a snap-in groove 12 is provided on the inner wall of the switch housing 1, and the snap-in block is snapped into the snap-in groove 12; the snap-in block is composed of an elastic sheet 33 and a snap-in head 34, and the snap-in head 34 is welded to the elastic sheet 33; the side wall of the snap-in groove 12 is an arc surface, and the side surface of the snap-in head 34 is an arc surface matching the side wall of the snap-in groove 12.

[0041] When used specifically:

[0042] Step 1: Install the sealing ring 4 by sleeve-mounting it on the plug-in ring 21, and insert the plug-in ring 21 into the top cavity of the switch housing 1; and as the plug-in ring 21 is inserted into the switch housing 1, the snap-in head 34 contacts the inner wall of the switch housing 1 to deform the elastic sheet 33. When the plug-in ring 21 is fully inserted, the snap-in head 34 is aligned with the snap-in groove 12, and the elastic sheet 33 recovers its deformation, driving the snap-in head 34 into the snap-in groove 12;

[0043] Step 2: Sleeve the fastening ring 3 on the annular notch 11 at the top of the switch housing 1, and use the bolts 5 to fix the first fixing block 31 and the second fixing block 35 of the fastening ring 3, so that the fastening ring 3 is tightened, thereby pressing the top of the switch housing 1, so that the sealing ring 4 is deformed;

[0044] Step 3: When the switch housing 1 or the cover plate 2 collides, even if the switch housing 1 or the cover plate 2 is deformed, the plug-in ring 21 is thick and will not be deformed, so the plug-in ring 21 and the fastening ring 3 can still clamp the sealing ring 4 to ensure the sealing effect.

[0045] Embodiment 3:

[0046] The difference from the first embodiment is that internal thread holes are provided at corresponding positions of the cover plates 2 on the switch housing 1 , and the cover plates 2 on the switch housing 1 are fixed by bolts.

[0047] When used specifically:

[0048] Step 1: Install, put the sealing ring 4 on the plug-in ring 21, insert the plug-in ring 21 into the top cavity of the switch housing 1, and use bolts to fix the switch housing 1 and the cover plate 2;

[0049] Step 2: Sleeve the fastening ring 3 on the annular notch 11 at the top of the switch housing 1, and use the bolts 5 to fix the first fixing block 31 and the second fixing block 35 of the fastening ring 3, so that the fastening ring 3 is tightened, thereby pressing the top of the switch housing 1, so that the sealing ring 4 is deformed;

[0050] Step 3: When the switch housing 1 or the cover plate 2 collides, even if the switch housing 1 or the cover plate 2 is deformed, the plug-in ring 21 is thick and will not be deformed, so the plug-in ring 21 and the fastening ring 3 can still clamp the sealing ring 4 to ensure the sealing effect.

[0051] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
