[0002] With the development of the Internet of Things, industrial remote monitoring, smart homes, etc., it has become a trend that more and more smart instruments need to be connected to the network, and network switches have also appeared. Network switches are a device for expanding the network and can provide more connection ports in sub-networks to connect more computers. However, network switches are exposed to the external environment for a long time, so they are easily contaminated with dust. Dust falling into the port can easily cause poor contact between the port and the network cable crystal head.

[0003] For example, the document with the prior art publication number CN113784228A provides a network switch based on a logical switch serial port, the device includes a switch body, an external board, a shielding mechanism, a clamping mechanism and a rotating mechanism, a plurality of network card interfaces are equidistantly provided on the front of the switch body, a top plate is mounted on the top of the switch body, the external board is fixedly connected to the front of the switch body, the shielding mechanism is arranged at the connection between the network card interface and the external board, the positioning mechanism is arranged at the connection between the protection block and the switch body, the clamping mechanism is arranged inside the switch body, and the rotating mechanism is arranged at the bottom end of the protection block. The device utilizes the design of the shielding mechanism, and the shielding mechanism can shield and protect the network card interface, so that the electrical components inside the network card interface of the switch body will not be exposed to the external environment, and dust in the external environment can be prevented from entering the inside of the network card interface and covering the copper wire inside the network card interface.

[0004] Although the device can shield the network card interface by using a shielding mechanism, after the crystal head is inserted into the network card connector, the shielding mechanism cannot shield the network card interface and the connection between the network card interface and the crystal head from dust, and when the device is subjected to tension between the switch body and the network cable, the crimping joint between the crystal head and the network cable and the crystal head and the switch body will be pulled, which is easy to cause poor contact and is not convenient for protecting the interface. In view of this, we propose a network switch based on a logical serial port. Utility Model Content

[0005] In order to make up for the shortcomings of the prior art, after the crystal head is inserted into the network card connector, the shielding mechanism cannot shield the network card interface and the connection between the network card interface and the crystal head from dust, and when the device is subjected to tension between the switch body and the network cable, the crimping joint between the crystal head and the network cable and the crystal head and the switch body will be pulled, which may easily cause poor contact problems.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4As shown, a network switch based on a logic serial port comprises: a switch body 1, a plurality of network cable interfaces 2 are evenly arranged on the switch body 1, a fixing ring 3 is arranged on the outer side of each network cable interface 2, a network cable 4 is plugged into the network cable interface 2 through a crystal head, and an outer cover body 5 is arranged on the outer side of the network cable 4; wherein, the outer cover body 5 comprises two semicircular outer cover shells 51, a boss 52 is arranged on the inner side of one end of each outer cover shell 51 for being snap-fitted and connected to the fixing ring 3, a card slot 53 is arranged on the inner side of the other end of each outer cover shell 51, and a clamping block 54 for clamping the network cable 4 is arranged in the card slot 53; legs 6 are installed at the four corners below the switch body 1, pin slots 55 are arranged on both sides of the two outer cover shells 51, and a card pin 56 is snap-fitted and connected in the pin slot 55;

[0023] When the switch body 1 is used to connect the network cable 4, the end of the network cable 4 is first crimped onto the crystal plug, and then the crystal plug is plugged into the network cable interface 2 of the switch body 1 for connection. In order to protect the network cable interface 2 and the network cable 4, the outer cover body 5 can be covered on the network cable interface 2 for dust protection. When installing the outer cover body 5, firstly, two semicircular outer cover shells 51 are respectively covered on the outside of the network cable interface 2 from both sides, and one end with the boss 52 is clamped on the fixing ring 3, and the side with the clamping block 54 in the clamping groove 53 is clamped and fixed on the outside of the network cable 4, and then the clamping pin 56 is clamped in the pin groove 55 to combine and fix the two semicircular outer cover shells 51, so as to achieve the effect of dust prevention.

[0024] The outer cover 5 can be used to prevent dust from entering the network cable interface 2, and after the network cable 4 is plugged into the network cable interface 2 using the crystal plug, it can still cover the network cable interface 2 and the outer side of the network cable 4 to prevent dust, thereby achieving a better dust-proof effect. In addition, one end of the outer cover 5 is snap-connected to the fixing ring 3 of the switch body 1, and the other end is clamped on the network cable 4. When the network cable 4 is pulled, the external force received can be directly transmitted to the switch body 1 through the outer cover 5, thereby eliminating or reducing the tension received by the network cable 4 and the crystal plug, avoiding the phenomenon of looseness at the crimping joint of the network cable 4 and the crystal plug causing poor contact, and achieving the purpose of protecting the interface.

[0025] The material of the clamping block 54 is rubber, the network cable 4 is placed in the groove of the clamping block 54, and the diameter of the groove is set to be the same as the diameter of the network cable 4;

[0026] The clamping block 54 is made of rubber material, which, on the one hand, protects the network cable 4 and avoids being pinched when the network cable 4 is clamped. In addition, the friction with the outside of the network cable 4 can be increased, and when the network cable 4 is subjected to tension, it can be transmitted to the outer cover 5, and then transmitted to the switch body 1 through the outer cover 5, thereby reducing the strong tension between the network cable 4 and the crystal head, and preventing the connection between the network cable 4 and the crystal head and the connection between the crystal head and the network cable interface 2 from loosening and causing poor contact. The clamping block 54 is provided with a groove to clamp the network cable 4, so that the network cable 4 can just fill the groove, which can not only play a role in clamping the network cable 4, but also prevent dust from penetrating into the network cable interface 2 from the gap in the groove.

[0027] The support leg 6 includes a base 61 fixedly connected to the switch body 1, each base 61 is installed with a suction cup 62, the material of the suction cup 62 is rubber material, the two bases 61 are connected to each other through a connecting pipe 7, and the connecting pipe 7 is connected to the air pump 8, the air pump 8 includes an air pump body 81, one end of the air pump body 81 is connected to the connecting pipe 7, a piston 82 is installed inside the air pump body 81, a pull rod 83 is connected to the piston 82, and the pull rod 83 is connected to the air pump body 81 through threaded engagement.

[0028] The support leg 6 with the suction cup 62 can be used to fix the switch body 1 on a desktop or a wall, thereby replacing the method of installing pins or setting brackets on the wall to fix the switch body 1, thereby achieving the purpose of reducing damage to the wall;

[0029] When the switch body 1 needs to be fixed on a wall or a table, the support leg 6 needs to be firstly brought into contact with the wall or the table, and the support leg 6 needs to be closely fitted with the wall or the table through the suction cup 62, and then the piston 82 is driven to move in the air pump body 81 of the air pump 8 by twisting the pull rod 83, so that the cavity volume of the air pump body 81 connected to the connecting pipe 7 becomes larger, in order to extract the air from the base 61 and the suction cup 62 through the connecting pipe 7, so that a vacuum is generated in the suction cup 62 and the base 61, and the switch body 1 is adsorbed and fixed on the table or the wall;

[0030] When the switch body 1 needs to be removed, pulling the switch body 1 vigorously may cause damage to the support feet 6 and the wall of the desktop or wall. The piston 82 can be driven to move in the air pump body 81 of the vacuum pump 8 by operating the pull rod 83, so that the cavity volume of the air pump body 81 connected to the connecting pipe 7 becomes smaller. The purpose is to fill the gas of the air pump body 81 into the base 61 and the suction cup 62 through the connecting pipe 7, so that the pressure of the base 61 and the suction cup 62 is close to the atmospheric pressure, thereby facilitating the removal of the switch body 1.

[0031] Working principle, when using the switch body 1 to connect to the network, first crimp the end of the network cable 4 onto the crystal head, and then plug the crystal head into the network cable interface 2 of the switch body 1 for connection. In order to protect the network cable interface 2 and the network cable 4, the outer cover body 5 can be covered on the network cable interface 2 for dust protection. When installing the outer cover body 5, first cover the two semicircular outer cover shells 51 from both sides on the outside of the network cable interface 2, and clamp one end with the boss 52 on the fixing ring 3, clamp the side with the clamping block 54 in the card slot 53 to the outside of the network cable 4, and then clamp the bayonet 56 in the pin slot 55 to combine and fix the two semicircular outer cover shells 51, thereby playing a dust-proof role.
