[0023] Embodiment: A fast encryption and decryption device for data transmission based on an embedded telemetry terminal, as Figures 1-8As shown in the figure, it includes a telemetry terminal body 1, a mounting substrate 2, a wiring head 3, a connector 50, a terminal block 6, a clamping member 7, a bolt 8, a pushing block 9, a limiting plate 10 and a spring 11. Mounting substrates 2 are provided on both sides of the telemetry terminal body 1. Mounting holes are provided on the two mounting substrates 2 for fixing the mounting substrates 2 on the wall surface, simplifying the installation process and ensuring the stability of the device. A number of symmetric wiring heads 3 are provided at the rear side of the telemetry terminal body 1. A threaded groove 4 is provided in the wiring end of the wiring head 3. Connection ports 5 are provided on both the front and rear sides of the telemetry terminal body 1. A connector 50 is plugged into each connection port 5 on one side. A terminal block 6 is provided on the front side of the telemetry terminal body 1. A clamping member 7 is clamped inside the terminal block 6. Bolts 8 are threadedly arranged between the clamping member 7 and the upper inner parts on both sides of the terminal block 6 for adjusting the position of the clamping member 7, so that the clamping member 7 can be easily disassembled and fixed, facilitating the wiring operation. At the lower part inside the telemetry terminal body 1, a pushing block 9 is slidably arranged below each connection port 5. The sliding part of each pushing block 9 inside the telemetry terminal body 1 is bent. Limiting plates 10 are provided at the upper ends of the bent parts of the pushing block 9 to limit the movement of the connector 50 and ensure its fixation. And the limiting plates 10 are slidably located at the lower inner ends of the connection ports 5. A spring 11 is provided between one side of each limiting plate 10 and the inner side of the telemetry terminal body 1 to provide a restoring force for the pushing block 9 and the limiting plate 10, ensuring that the limiting plate 10 can return to its original position without external force, thereby ensuring the stability of the connector 50. A positioning groove 12 is provided on the upper side inside each connection port 5 of the telemetry terminal body 1 to provide a positioning point for the limiting inclined block 14, ensuring that the connector 50 can be correctly fixed and improving the reliability of the connection.
[0024] As Figures 3-6 shown, it further includes a rotating shaft 13, a limiting inclined block 14 and a torsion spring 15. A rotating shaft 13 is rotatably arranged between the two inner wall surfaces of each connection port 5. Limiting inclined blocks 14 are rotatably arranged on both sides of each rotating shaft 13 for being inserted into the positioning holes of the connector 50 to fix the connector 50, ensuring the stability of the connector 50 and preventing it from falling off during use. The upper part of each limiting inclined block 14 is rotatably abutted in the adjacent positioning groove 12. And a torsion spring 15 is provided between the rotating connection points of both sides of each rotating shaft 13 and the inner wall surface of the connection port 5 to provide a restoring force for the rotating shaft 13, ensuring that the limiting inclined block 14 can automatically be inserted into the positioning hole after the connector 50 is inserted, enhancing the stability of the connector 50. The insertion end of the connector 50 is in rotational contact with the limiting inclined block 14, and the limiting inclined block 14 is rotatably inserted into the self - provided positioning hole on the insertion end of the connector 50.
[0025] As Figure 1 and Figure 3 and Figures 7-8As shown in the figure, it further includes an isolation block 16. An isolation block 16 is provided at the bottom of each port inside the terminal block 6. The isolation block 16 is made of rubber material, which can prevent the signal wiring from directly contacting the port of the terminal block 6 and avoid the possible wear and short - circuit problems during the wiring process.
[0026] During use, first, the device is docked on the designated installation wall surface through the mounting substrate 2. Then, a tool is used to pass through the mounting holes on the mounting substrate 2 to fix the whole device on the installation wall surface. At this time, the whole device is already installed, and the wiring operation of the telemetry terminal can be carried out. When the signal wiring needs to be plugged into the terminal block 6, the bolt 8 is removed from the clamping member 7 in advance, so that the clamping member 7 is no longer firmly set. Then, the clamping member 7 is pulled out, and the signal wiring is plugged into the terminal block 6 one by one. The bottom of the signal wiring will abut against each isolation block 16 one by one and will not directly contact the port of the terminal block 6, thus avoiding wear on the metal head of the signal wiring during the plugging process. After completion, the clamping member 7 is reinstalled into the terminal block 6. The lower part of the clamping member 7 will abut against the upper part of each signal wiring at one time. And as the clamping member 7 slowly resets, each signal wiring will be firmly fixed. When the clamping member 7 is almost reset and can abut against and contact each signal wiring, the bolt 8 is used again to fix the clamping member 7 and the terminal block 6, thus completing the unified fixation of all signal wirings.
[0027] When it is necessary to connect the power line and the control line to the wiring head 3 of the telemetry terminal, a sleeve matching the thread groove 4 of the wiring head 3 should be used. The sleeve is sleeved outside the power line and the control line, and the sleeve is connected to the wiring head 3 through thread matching to achieve the fixation of the power line and the control line.
[0028] When it is necessary to plug the corresponding connector 50 into each connection port 5, first slide the push block 9 backward. The push block 9 squeezes the spring 11 on one side to deform and compress it. Then, pull out the limit inclined block 14 from the positioning groove 12. The limit inclined block 14 drives the rotation of the rotating shaft 13, and the rotating shaft 13 drives the deformation and tightening of the torsion springs 15 on both sides. At this time, insert the connector 50 through the connection port 5. The access end of the connector 50 will contact the inner limit inclined block 14. At this moment, gradually release the limit inclined block 14. The torsion spring 15 will no longer be driven to tighten by the rotational force and will deform and expand by its self-expanding force, thereby driving the rotation of the rotating shaft 13 and the limit inclined block 14, and following the connector 50 during the insertion process. When the access end of the connector 50 touches the inner end of the connection port 5, the insertion process is completed at this time. The upper part of the limit inclined block 14 during the rotation process will rotate and snap into the positioning hole provided by the access end of the connector 50 and gradually reset into the upper positioning groove 12. At this moment, the sliding of the push block 9 can be stopped. The push block 9 will be driven to reset by the self-expanding force of the spring 11 and contact the lower part of the access end of the connector 50 to hold it against, so that the connector 50 can be fixed. After the torsion spring 15 and the spring 11 are completely restored to their initial states, the connector 50 is completely fixed and cannot be pulled out randomly. When it is necessary to replace the connector 50 subsequently, slide the push block 9 backward again so that the lower part of the connector 50 can no longer be held against. At this time, the connector 50 can be directly removed by a downward force and then a backward force. When removing, the limit inclined block 14 will also rotate. Subsequently, as the connector 50 is completely removed, it will rotate and reset according to the action of the torsion spring 15. The above completes the connection step.
