As shown in fig. 9-11, a crystal head 2 corresponding to the networking interface 101 is disposed on one side of the switch housing 1, the crystal head 2 includes an elastic sheet and a butt joint, the elastic sheet is integrally formed above the butt joint, the stabilizing portion 8 is assembled inside the networking interface 101, the crystal head includes a projection 801 corresponding to a gap between the elastic sheet and the butt joint, and after the crystal head 2 is inserted into the networking interface 101, the projection 801 can be engaged with the gap between the elastic sheet and the butt joint.

When networking work of the switch is required, an operator only needs to insert the crystal head 2 into the networking interface 101, and then the projection 801 can move into a gap between the elastic sheet and the butt joint by matching with the action of the stabilizing part 8, and at the moment, the crystal head 2 cannot be separated from the inside of the networking interface 101;

it should be noted that, the networking interface 101 may be provided in plural, and the same stabilizing portion 8 is also provided inside the networking interface 101, and correspondingly, the communication interface is also applicable to the stabilizing portion 8, and the networking interface 101 is taken as an example in the present solution for demonstration and explanation.

As shown in fig. 10 and 11, the stabilizing portion 8 further includes a linkage push rod 802 and an extrusion rod 803, the linkage push rod 802 is rotatably connected inside the networking interface 101, the linkage push rod 802 is L-shaped and corresponds to one side of the bump 801, the extrusion rod 803 is slidably inserted into the networking interface 101, the top of the extrusion rod 803 is flush with one end of the linkage push rod 802, when the extrusion rod 803 is displaced toward the inside of the networking interface 101, the linkage push rod 802 is stressed and rotates inside the networking interface 101, one end of the extrusion rod 803 is fixedly connected with a return spring, and one end of the return spring is fixedly connected with the inside of the networking interface 101.

Specifically, when networking of a plurality of switches is required, an operator presses the elastic sheet and makes the elastic sheet attached to the butt joint, and then inserts the butt joint into the networking interface 101, in the process, the extrusion rod 803 is gradually stressed and moves towards the inside of the networking interface 101, the extrusion rod 803 extrudes the linkage push rod 802, the linkage push rod 802 rotates relative to the networking interface 101 and extrudes the bump 801, the bump 801 gradually displaces towards the gap between the elastic sheet and the butt joint, when the docking head is completely inserted into the networking interface 101, the protrusion 801 enters the gap between the elastic piece and the docking head, and the docking head is limited in the networking interface 101, even if an external force touches the conducting wire on the butt joint, the butt joint can not slide out of the inside of the networking interface 101, and therefore stability of networking among the multiple switches can be guaranteed.

As shown in fig. 11, an installation groove 8011 is formed inside the protrusion 801, a driving rod 8012 corresponding to the linkage pushing rod 802 is slidably sleeved inside the installation groove 8011, a cross section of the driving rod 8012 is T-shaped, an elastic resetting piece 8013 is disposed on a side of the driving rod 8012 opposite to an inner wall of the installation groove 8011, the elastic resetting piece 8013 is in an unstressed state initially, and the driving rod 8012 is attached to an inner wall of the installation groove 8011 under extrusion of the elastic resetting piece 8013.

In addition, the elastic sheet is divided into a straight section and an elastic section, the straight section is always attached to the outer side of the butt joint, and the elastic section is initially in an outward opening state;

on the basis, when the butt joint and the elastic sheet are displaced towards the inside of the networking interface 101 and the butt joint applies a pressing force to the pressing rod 803, the straight section of the networking interface 101 blocks the convex block 801, at this time, the driving rod 8012 is pressed by the linkage push rod 802, so that the driving rod 8012 moves toward the inside of the mounting groove 8011, and presses the elastic resetting piece 8013, at this time, the elastic resetting piece 8013 is in a contraction and force accumulation state, when the installation of the butt joint is completed and the operator releases the pressing of the elastic piece, the gap between the elastic piece and the butt joint is just aligned with the bump 801, at this time, the bump 801 is pressed by the elastic reset piece 8013, and the projection 801 is gradually moved into the gap by the pressing of the elastic reset piece 8013, therefore, the crystal head 2 cannot shift transversely relative to the networking interface 101, and the stability of networking of a plurality of switches cannot be damaged.

As shown in fig. 10 and 11, the inside of the networking interface 101 is further slidably sleeved with a cambered plate 14, the cambered plate 14 is located on one side above the convex block 801, one side of the cambered plate 14 is fixedly connected with a connecting block 1401, and one end of the connecting block 1401 is fixedly connected with one side of the convex block 801.

According to the above structure, when the networking state of the switch needs to be released, an operator only needs to press the elastic sheet, the elastic sheet will displace towards the direction close to the butt joint, at this time, the elastic sheet will press the arc panel 14, the arc panel 14 will move towards the inside of the networking interface 101, the arc panel 14 drives the bump 801 to displace towards the inner side of the networking interface 101 through the connecting block 1401, and then the bump 801 gradually moves out from the gap between the elastic sheet and the butt joint, and then the subsequent operator can directly extract the crystal head 2 from the inside of the networking interface 101, during the process of extracting the crystal head 2, the butt joint will gradually leave away from the extrusion rod 803, at this time, the reset spring will alone apply a squeezing force to the extrusion rod 803, and then the extrusion rod 803 will gradually leave the linkage push rod 802, at this time, the linkage push rod 802 will receive the squeezing force of the elastic reset piece 8013 transmitted from the driving rod 8012, and then the linkage push rod 802 will reversely rotate and gradually reset, the bump 801 and the cambered plate 14 do not form a protrusion inside the networking interface 101 after the crystal head 2 is completely pulled out.

It should be noted that, when the operator is in other power consumption parts in the maintenance rack, because the exposed part of flexure strip is less, can not direct atress many times, even touch the used wire of network deployment on the switch, the wire atress also only can transversely pull quartzy head 2, can not lead to the fact the influence to the flexure strip, and then the flexure strip just can not extrude cambered plate 14, just can not lead to the fact the influence to lug 801 yet, quartzy head 2 just can be pegged graft in the inside of network deployment interface 101 stable always so, thereby make the network deployment between the switch can not receive the influence.

The working principle of the invention is as follows: when the switch is connected with an external power supply and operates, the heat dissipation fan 301 can also operate synchronously, further, external air flow can be introduced into the interior of the integrated shell 4 through the air inlet 102, the introduced air flow can be cooled through the condensation module 6, after the amount of condensate accumulated in the condensation cavity 402 reaches a preset value, the condensate can be sprayed into the interior of the heat dissipation cavity 401 under the action of the cooling part 5, so that heat in the interior of the heat dissipation cavity 401 is neutralized, the temperature of the air flow discharged into the interior of the switch shell 1 is relatively low, heat generated by the integrated circuit board and electric elements above the integrated circuit board can be neutralized, the air pressure in the interior of the switch shell 1 can be gradually discharged to the outside through the air outlet 103, and when networking work of the switch is required, an operator only needs to insert the crystal head 2 into the networking interface 101, the cooperating stabilizer 8 then acts to move the projection 801 into the gap between the spring plate and the docking head, so that the crystal head 2 does not fall out of the inside of the networking interface 101.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be construed as the protection scope of the present invention.
