[0022] like Figure 1 As shown, the present invention provides a technical solution: a quick-connect, pressure-free terminal with a monitoring device that can be used multiple times, comprising: a tube base 1, an outer sheath 6, a wire 9, and a locking assembly;

[0023] The outer sleeve 6 is provided around the tube seat 1 to prevent damage to the tube seat 1;

[0024] A locking assembly is provided on the inner side of the tube seat 1;

[0025] One end of the wire 9 is used to insert into the tube socket 1 and fix it by the locking assembly.

[0026] like Figure 2 As shown, the tube seat 1 also includes a pressure port 101, a fixing hole 102, an inclined slot 103, a fixing post 104, an inner groove 105, and a placement groove 106; the upper part of the tube seat 1 has a pressure port 101, the side wall of the pressure port 101 has three inclined slots 103, the three inclined slots 103 are provided with fixing posts 104, the side wall of the pressure port 101 also has a fixing hole 102, the inner side of the tube seat 1 has an inner groove 105, and the top side wall of the tube seat 1 has a placement groove 106.

[0027] like Figures 3-5 As shown, the locking assembly includes a clamping block 3, a pre-tightening spring 5, an inner bushing 7, and a pressure block 8; one end of the clamping block 3 is located on the upper part of the fixing post 104, the lower part of the fixing post 104 is provided with the pre-tightening spring 5, the inner bushing 7 is located in the inner groove 105, and the pressure block 8 is located in the pressure port 101.

[0028] The preload spring 5 has two long tentacles, which abut against the clamping block 3 and the tube seat 1 respectively; the preload spring 5 keeps the clamping block 3 in a closed state at all times.

[0029] The clamping block 3 includes a hexagonal hole 301 and a slot outer edge 302. The top wall of the clamping block 3 has a hexagonal hole 301, and the clamping block 3 is shaped like a conch shell. The side of the clamping block 3 has a slot outer edge 302, which is used to push the clamping block 3 to rotate outward when the wire 9 enters the tube seat 1, so as to open the pre-tightening spring 5. After the wire 9 is fully inserted into the tube seat 1, the elasticity of the pre-tightening spring 5 can keep the slot outer edge 302 of the clamping block 3 tightly attached to the wire 9 without loosening, so that the tube seat 1 and the wire 9 fit more tightly and firmly, and the current transmission is smoother.

[0030] The inner sleeve 7 includes an inner edge 701 of a slot. The inner sleeve 7 has an inner edge 701 of a slot, which has a serrated feature. When the wire 9 is pulled outward, the serrated feature works together with the outer edge 302 of the slot of the clamping block 3 to firmly lock the wire 9, so as to prevent it from falling off and to ensure smooth current transmission.

[0031] Both the outer edge 302 and the inner edge 701 of the card slot have serrated features.

[0032] The pressure block 8 includes an upper opening 801 and a lower bolt hole 802. The bottom of the pressure block 8 is provided with two lower bolt holes 802, which are used to install the pressure block 8 in the pressure port 101 and fix it by inserting the fastening bolt 4 into the fixing hole 102 and the lower bolt hole 802. The top of the pressure block 8 is provided with an upper opening 801, which is used to align the pressure block 8 in the pressure port 101 with the hexagonal hole 301. When it is necessary to remove the wire 9, the hexagonal wrench is inserted into the hexagonal hole 301 from the upper opening 801 and rotated to rotate the hexagonal hole 301 outward, so that the outer side 302 of the slot is separated from the side in contact with the wire 9, and the wire 9 can be removed.

[0033] Among them, the outer surface of the tube seat 1 is provided with an outer sheath 6; the outer tube of the tube seat 1 and the outer insulating rubber of the wire 9 are in an interference fit state to prevent moisture and dust from entering, and to always protect the internal connection parts, and prevent aging and excessive resistance caused by oxidation.

[0034] The monitoring chip 2 is installed in the placement slot 106 and is used to monitor the installation status of the wire 9, collect operating parameters, and perform data interaction and acceptance. The monitoring chip 2 specifically includes a position sensing module, a parameter acquisition module, a wireless communication module, an NFC interaction module, a main control processing module, and a power supply module. The modules are electrically connected and work together to complete the monitoring and acceptance functions.

[0035] Workflow:

[0036] Before connecting wire 9, the initial state preparation of the device is completed. An outer sheath 6 is fitted around the tube seat 1 to form a protective structure for the tube seat 1, preventing the tube seat 1 from being damaged by external collisions and wear. At the same time, an inner bushing 7 is pre-installed in the inner groove 105 on the inner side of the tube seat 1. The inner edge 701 (serrated) of the groove of the inner bushing 7 is in a locked state. A pressure block 8 is installed in the upper pressure port 101 of the tube seat 1. The pressure block 8 is fixed to the tube seat 1 by inserting the fastening bolt 4 into the fixing hole 102 and the lower bolt hole 802 of the pressure block 8. The upper opening 801 of the pressure block 8 is aligned with the hexagonal hole 301 of the clamping block 3. The clamping block 3 is mounted on the upper part of the fixing post 104 of the tube seat 1. The pre-tension spring 5 is connected to the lower part of the fixing post 104. The two long tentacles of the pre-tension spring 5 abut against the clamping block 3 and the tube seat 1 respectively, so that the clamping block 3 is always in a closed state. The outer edge 302 (serrated) of the slot of the clamping block 3 fits against the inner wall of the tube seat 1. Finally, the monitoring chip 2 in the placement slot 106 on the top side wall of the tube seat 1 is powered on and started, so that the monitoring chip 2 enters the monitoring state.

[0037] After the initial preparation is completed, the wire 9 is inserted and locked. One end of the wire 9 is aligned with the inner groove 105 of the tube seat 1 and inserted. The wire 9 pushes the closed locking block 3 to rotate outward. The locking block 3 squeezes the pre-tightening spring 5, causing the pre-tightening spring 5 to deform. The wire 9 is inserted until it is completely inserted into the tube seat 1 and reaches the specified insertion length. At this time, the deformation force of the pre-tightening spring 5 is released, pushing the locking block 3 to reset. After the locking block 3 is reset, the outer edge 302 (serrated) of the slot is tightly attached to the outer wall of the wire 9. At the same time, the inner edge 701 (serrated) of the slot of the inner bushing 7 cooperates with the outer edge 302 of the slot to firmly lock the wire 9 in the tube seat 1, preventing the wire 9 from loosening or falling off. The outer tube of the tube seat 1 and the outer insulating rubber of the wire 9 form an interference fit, blocking moisture and dust from entering the interior of the tube seat 1, protecting the internal connection parts, and avoiding aging and excessive resistance caused by oxidation.

[0038] After wire 9 is locked, the real-time monitoring and acceptance phase begins. Monitoring chip 2 senses the position of wire 9 via infrared. If wire 9 reaches the specified insertion length, the green light on monitoring chip 2 illuminates, indicating that wire 9 is installed correctly. If the specified length is not reached, the red light illuminates, and the insertion depth of wire 9 needs to be readjusted. At the same time, monitoring chip 2 collects the current magnitude and surface temperature data of the connection between wire 9 and socket 1 in real time, and transmits the data to an external receiver via harmonics or infrared to achieve status monitoring during operation. In the acceptance phase, a handheld device is connected to the NFC function of monitoring chip 2 to read the position data of wire 9, confirming whether wire 9 is in the specified insertion position, and completing the installation acceptance.

[0039] When it is necessary to remove wire 9, proceed with the wire 9 unlocking and removal process. Insert the hex wrench into the hexagonal hole 301 of the clamping block 3 through the upper opening 801 of the pressure block 8. Rotate the hex wrench to drive the clamping block 3 to rotate outward around the fixed post 104, so that the outer edge 302 of the clamping block 3 is disengaged from the outer wall of the wire 9, releasing the locking of the outer edge 302 and the inner edge 701 of the clamping block 3 on the wire 9. Keep the hex wrench in a rotating state and pull the wire 9 outward until the wire 9 is completely removed from the inner groove hole 105 of the tube seat 1. After removing the wire 9, release the hex wrench, and the pre-tension spring 5 pushes the clamping block 3 to reset to the closed state. The device returns to the initial insertion state and can be used for the next wire 9 connection operation.
