[0028] The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, and use. It should be understood that in all of these figures, the same or similar reference numerals indicate the same or similar parts and features. The various drawings only schematically represent the concepts and principles of the embodiments of the present disclosure, and do not necessarily show the specific dimensions and proportions of the various embodiments of the present disclosure. Specific parts in specific drawings may be exaggerated to illustrate the relevant details or structures of the embodiments of the present disclosure.

[0029] Example

[0030] See also Figure 1 As shown, a computer network tap includes a tap 1, and a plurality of ports 101 are evenly embedded and fixed on the outer surface of the tap 1. The ports 101 are used to connect to a crystal head. The specific specifications of the ports 101 in this embodiment are selected according to the actual needs of those skilled in the art and are not specifically limited here. One of the ports 101 is a female port, that is, it is used to connect to a network cable crystal head providing a network, and the remaining ports 101 are tap ports, that is, a network cable providing a network is tapped into a plurality of networked tap ports for connection to the crystal heads of a plurality of network cables.

[0031] For details, see Figure 1 and Figure 2 As shown, it also includes a head removal mechanism 2, a drive component 3 and a servo slide 4. The servo slide 4 is fixed to the surface of the splitter 1, the drive component 3 is assembled on the output part of the servo slide 4, the head removal mechanism 2 is assembled at the end of the drive component 3, the head removal mechanism 2 is used to release the crystal head lock and clamp the crystal head, the drive component 3 is used to drive the head removal mechanism 2 to axially displace and radially flip, and the servo slide 4 is used to drive the drive component 3 to move the crystal head clamped by the head removal mechanism 2 to any port 101.

[0032] For example, in some unattended areas, if a physical fault is caused by port 101, the drive assembly 3 is driven to work by remote network control, so that the head removal mechanism 2 clamps the crystal head in the faulty port 101 and takes it out and reverses it, and then the servo slide 4 moves the drive assembly 3 and the head removal mechanism 2 to the vacant port 101 for insertion. If the network is restored, there is no need to arrange personnel to go immediately, and the faulty port 101 can be replaced during the next routine maintenance;

[0033] Or re-plug the crystal head in the faulty port 101. If the network is restored, there is no need to arrange personnel to go, because the metal contacts of the crystal head and the port 101 will be oxidized due to the use environment, resulting in poor contact. Re-plugging will cause the metal contacts on the crystal head and the contacts in the port 101 to rub against each other, which will remove the oxide layer and solve the problem.

[0034] The purpose is to save personnel time required for network maintenance, improve the efficiency of solving physical problems caused by port 101, and quickly solve such problems in some extreme environments to avoid chain losses caused by network disconnection, such as space stations, forest fire detection equipment and other areas that are difficult for personnel to reach immediately.

[0035] For more details, see Figure 2 and Figure 6As shown, the head removal mechanism 2 includes a bracket 21, a clamping arm 22, a connecting rod 23, a sleeve 24 and a pressure rod 25. The outer surface of the clamping arm 22 is hinged to the bracket 21, and the clamping arm 22 is provided with at least two and symmetrically designed. One end of the connecting rod 23 is hinged to the end of the clamping arm 22, and the other end is hinged to the sleeve 24. The pressure rod 25 runs through the sleeve 24 and the bracket 21, and the pressure rod 25 is slidably connected to the sleeve 24 and the bracket 21 in turn. The pressure rod 25 is used to drive the sleeve 24 to translate up and down and push the crystal head lock tongue. First springs 241 are provided on both sides of the sleeve 24, and the first springs 241 are sleeved on the pressure rod 25. One end of the two first springs 241 is against the sleeve 24, and the other ends of the two first springs 241 are respectively The two first springs 241 are against the bracket 21 and the pressure rod 25, and are used to provide elastic force for the sleeve 24, so that when the pressure rod 25 is pressed down, the first spring 241 can provide elastic force to squeeze the sleeve 24 downward. The first spring 241 located below the sleeve 24 is used to provide elastic force for the sleeve 24 to reset, and the first spring 241 is used to realize the linkage between the pressure rod 25 and the squeezing sleeve 24, so that the displacement distance of the sleeve 24 can be controlled to be smaller than the displacement distance of the pressure rod 25, so that the distance between the clamping arm 22 and the crystal head can be designed to be smaller than the unlocking distance of the crystal head lock tongue, that is, before the pressure rod 25 completes unlocking the crystal head lock tongue, the clamping arm 22 can clamp the crystal head, and the clamping force is continuously increased with the contraction of the first spring 241;

[0036] Exemplarily, by pressing down the pressure rod 25, the lock tongue on the surface of the crystal head can be pushed down to unlock the crystal head, and the pressure rod 25 drives the sleeve 24 to move downward through the first spring 241, and the sleeve 24 can drive the clamping arm 22 to move toward the pressure rod 25 through the connecting rod 23 to clamp the crystal head.

[0037] For further information, see Figure 5 and Figure 7 As shown, a through hole 251 and a limiting groove 252 are provided on the outer surface of the pressure rod 25, and a limiting card 211 is slidably connected in the bracket 21, and the limiting card 211 passes through the through hole 251 and is slidably connected to the through hole 251, which does not affect the up and down translation of the pressure rod 25, and a second spring 2111 for providing elastic force for the limiting card 211 is sleeved on the end of the limiting card 211, and the limiting card 211 is used to cooperate with the limiting groove 252 to limit the pressure rod 25;

[0038] Exemplarily, when the pressure rod 25 squeezes the crystal head lock tongue until the crystal head is unlocked, the limit slot 252 moves to be flush with the top of the limit card 211. At this time, the head removal mechanism 2 only needs to be translated toward the outside of the port 101. Since the second spring 2111 provides elastic force for the limit card 211, the limit card 211 and the pressure rod 25 can be engaged. In this way, even after the head removal mechanism 2 pulls the crystal head out of the port 101, the clamping arm 22 can maintain the state of clamping the crystal head, and the crystal head lock tongue is also in an unlocked state, ensuring that the crystal head can be reinserted or replaced in the port 101. After being inserted into the port 101, the tail of the limit card 211, that is, facing the tap 1, abuts against the tap 1, so that the limit card 211 leaves the limit slot 252. At this time, the first spring 241 releases the elastic force to reset the sleeve 24 and drive the pressure rod 25 to reset, contacting the clamping of the crystal head and the squeezing of the crystal head lock tongue, so that the crystal head completes the insertion and removal in the port 101.

[0039] For further information, see Figure 3 , Figure 4 and Figure 8 As shown, the driving assembly 3 includes a fixed shell 31, a lever 32, a connecting shaft 33, a motor 34 and an electric push rod 35. The lower surface of the fixed shell 31 is fixedly connected to the output end of the servo slide 4. The lever 32 is rotatably connected to the fixed shell 31 to push the pressure rod 25 to move up and down. A cam 321 is fixed to the end of the lever 32, and the cam 321 is against the pressure rod 25. The connecting shaft 33 passes through the fixed shell 31 and is rotatably connected to the fixed shell 31, and the end of the lever is fixedly connected to the bracket 21. The outer surface of the connecting shaft 33 is sleeved with a first gear 322, the outer surface of the connecting shaft 33 is sleeved with a second gear 331 for cooperating with the first gear 322, the motor 34 is fixed in the fixed shell 31, and the output end of the motor 34 is fixedly connected to the lever 32, for driving the lever 32 to rotate, the electric push rod 35 is fixed in the fixed shell 31, the output end of the electric push rod 35 is rotatably connected to the pulling sleeve 351, and the output end of the electric push rod 35 is linked with the end of the connecting shaft 33 through the pulling sleeve 351;

[0040] Exemplarily, the motor 34 drives the lever 32 to rotate, which can drive the cam 321 to rotate and squeeze the pressure rod 25 until the pressure rod 25 stops rotating after reaching the target stroke. The electric push rod 35 pushes the connecting shaft 33 to translate outside the fixed shell 31, and the crystal head is pulled out of the port 101. At this time, the second gear 331 translates axially with the connecting shaft 33 until it is limited by the fixed shell 31 and meshes with the first gear 322. At this time, the motor 34 continues to drive the lever 32 to rotate, and the first gear 322 and the second gear 331 cooperate to drive the connecting shaft 33 to rotate, thereby driving the head removal mechanism 2 to flip, see Figure 8As shown, when the servo slide 4 drives the driving component 3 to translate along the arrangement path of multiple ports 101, it will not be interfered by the adjacent crystal heads. After translating to the target port 101, the motor 34 is reversed to reset the crystal head. The electric push rod 35 is reset and the crystal head can be inserted into the port 101.

[0041] It is worth mentioning that when the electric push rod 35 is reset, when the second gear 331 leaves the first gear 322, the motor 34 continues to reverse and returns to a state where the push rod 25 is not squeezed, that is, Figure 6 The state shown avoids affecting the reset of the pressure rod 25.

[0042] It should be noted that the specific models of the motor 34, electric push rod 35 and servo slide 4 in this embodiment are determined according to actual conditions. The remote control method and program setting can be designed by technicians in this field according to the above process to design an automated motion program, and no specific limitations are made here.

[0043] For further information, see Figure 6 As shown, one end of the clamping arm 22 away from the connecting rod 23 is hinged with a clamping claw 221, the purpose of which is to avoid reducing the contact area with the crystal head when the clamping arm 22 rotates. Since the clamping claw 221 is rotatably connected to the clamping arm 22, no matter how the clamping arm 22 rotates, the clamping claw 221 can fit the crystal head to improve the clamping effect.

[0044] The exemplary implementation scheme of the present disclosure is described in detail above with reference to the preferred embodiments. However, it can be understood by those skilled in the art that, without departing from the concept of the present disclosure, various modifications and variations can be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present disclosure can be combined in various ways without exceeding the protection scope of the present disclosure, which is determined by the attached claims.
