Description

Technical Field

[0001] The utility model relates to the technical field of thermal simulation, in particular to a thermocouple wire quick connection device. Background Art

[0002] Steel plates can achieve excellent mechanical properties through heat treatment. Currently, the number of steel plates heat treated in continuous annealing and galvanizing lines is increasing year by year. To optimize heat treatment process curves, the temperature changes that affect the mechanical properties of steel plates must be accurately measured. Thermal simulation can significantly reduce the cost of optimizing heat treatment processes, leading to the rapid development of thermal simulation testing machines that measure heat treatment processes and product performance.

[0003] A thermal simulation tester can replicate the annealing curves of various zones in the annealing furnace of a continuous annealing line or galvanizing line in the laboratory. This requires welding multiple thermocouples onto steel plates to monitor their temperature. Welding thermocouples onto steel plates takes a long time, requiring the completion of the previous experiment before welding the next plate to the thermocouple. This long welding time makes the experiment intermittent, preventing continuous testing and resulting in low efficiency, making it difficult to meet the thermal simulation needs of specialized applications. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, the utility model provides a thermocouple wire quick connection device. By setting joint one and joint two, the experimenter can quickly connect the thermocouple wire welded on the steel plate to the thermal simulation test machine for thermal simulation, thereby improving the connection efficiency. After the thermal simulation experiment of the first steel plate is completed, joint one can be immediately connected to joint two connected to the thermocouple wire welded to the next steel plate, thereby realizing a quick connection experiment between the thermocouple wire of the second steel plate and the thermal simulation test machine, thereby improving the experimental efficiency and the utilization efficiency of the thermal simulation test machine.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A thermocouple wire quick connection device includes a connector 1 and a connector 2. The connector 1 is set on a thermal simulation test machine. The connector 1 includes a shell 1. A slot is provided on one side wall of the shell. A spring electrode piece is provided in the slot. The connector 2 includes a shell 2 and a plug. The plug is set on the second side wall of the shell. The plug is inserted into the slot. The end of the plug contacts and cooperates with the spring electrode piece. The plug includes a conductive rod and a plurality of conductive sheets connected to the head of the conductive rod. A contraction groove is provided between two adjacent conductive sheets.

[0007] Furthermore, the thermocouple wire quick connection device also includes a magnetic ring 1 and a magnetic ring 2, wherein the magnetic ring 1 is arranged on the side wall surface of the shell 1 where the slot is provided, and the magnetic ring 2 is arranged on the side wall surface of the shell 2 where the plug is provided.

[0008] Furthermore, the magnetic poles of the magnetic ring 1 and the magnetic ring 2 are opposite.

[0009] Furthermore, the conductive sheet is provided with a second bevel on one side and a third bevel on the other side. The slot is provided with a first bevel, and the first bevel is in contact with the third bevel.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. By setting up joint 1 and joint 2, the experimenter can quickly connect the galvanic wire welded on the steel plate to the thermal simulation test machine for thermal simulation, thereby improving the connection efficiency of the galvanic wire, improving the experimental efficiency, reducing the labor intensity of the experimenter, and shortening the experimental time.

[0012] 2. During the thermal simulation experiment, the experimenter can weld the next steel plate to the thermocouple wire and connect the thermocouple wire to the second joint. After the thermal simulation experiment of the first steel plate is completed, the first joint and the second joint connected to the thermocouple wire on the second experimental steel plate are quickly connected to achieve a quick connection between the second steel plate thermocouple wire and the thermal simulation test machine, thereby improving the experimental efficiency and the use efficiency of the thermal simulation test machine, and realizing the requirements of batch thermal simulation experiments, thereby meeting the needs of fast or large-scale thermal simulation processes.

[0013] 3. By setting a retractable conductive sheet to squeeze the spring electrode sheet after it enters the slot, the third bevel can fit tightly with the first bevel, and then the mutual cooperation of the magnetic ring 1 and the magnetic ring 2 is used to make the connection effect between the first connector and the second connector better, prevent the plug from moving and misaligning, improve the reliability of the connection, improve the contact between the plug and the spring electrode sheet, improve the accuracy of the experimental measurement, and ensure the stability of the thermal simulation results of the steel plate.

[0014] 4. The second inclined surface provided on one side of the conductive sheet plays a role of guiding and assisting contraction when the plug is inserted into the slot, making it easier for several conductive sheets on the plug to contract and extend into the slot, speeding up the insertion of the plug and the slot, increasing the connection speed, reducing the labor intensity of the operator, improving the connection efficiency of the thermocouple wire, improving the experimental efficiency, and reducing the experimental time.

[0015] 5. Inclined surface 3 and inclined surface 1 serve as guides when the plug is pulled out of the slot, making it easier to pull out the plug, increasing the plug-in and pull-out speed, improving the separation efficiency, and shortening the time for replacing the test steel plate.

[0021] The specific implementation of the utility model is further described below:

[0022] like Figures 1-4 As shown, a thermocouple quick-connect device includes a second connector and a first connector mounted on a thermal simulation test machine for mating with the second connector. A thermocouple wire is fixed to the side wall of the second connector. The thermocouple wire comprises two different materials, preferably nickel chromium and nickel. The two different thermocouple wires are welded to corresponding positions on opposite sides of a steel plate. The first connector includes a housing 1 and a slot 3 formed on its inner wall. The second connector includes a housing 2 and a plug 4 fixed to the side wall of the housing 2. The plug 4 is movably inserted into the slot 3. The inner wall of the slot 3 is provided with a spring electrode sheet 11, and the end of the plug 4 contacts and mates with the spring electrode sheet 11. The plug 4 comprises a conductive rod 7 and a plurality of conductive sheets 5 connected to the ends of the conductive rods 7. A contraction groove 6 is provided between two adjacent conductive sheets 5. A second bevel 12 is provided on one side of the conductive sheet 5, and a third bevel 13 is provided on the other side of the conductive sheet 5. The slot 3 is provided with a first bevel 8 that mates with the third bevel 13. Magnetic ring 1 9 and magnetic ring 2 10 are fixed to the opposing side walls of housing 1 1 and housing 2 2 , respectively. Magnetic ring 1 9 and magnetic ring 2 10 have opposite magnetic poles. When plug 4 is inserted into slot 3 , bevel 2 12 first contacts the slot 3 notch, then the slot wall compresses the entire conductive sheet 5, causing it to contract. Once the conductive sheet 5 is fully inserted into slot 3 , housing 1 1 and housing 2 2 adhere to each other via magnetic ring 1 9 and magnetic ring 2 10 . At this point, the conductive sheet 5 is unrestricted and returns to its open state. Bevel 2 12 presses the spring electrode sheet 11 inward, which in turn pushes bevel 2 12 outward. Together with magnetic ring 1 9 and magnetic ring 2 10 , bevel 3 13 fits tightly against bevel 1 8 . By providing a retractable conductive sheet 5 and squeezing the spring electrode sheet 11 against each other after the conductive sheet enters the slot 3, the inclined surface 3 13 can fit tightly against the inclined surface 1 8. Then, by utilizing the mutual cooperation between the magnetic ring 1 9 and the magnetic ring 2 10, the connection effect between the joint 1 and the joint 2 is improved, thereby ensuring the stability of the thermal simulation results of the steel plate.

[0023] The thermal simulation test machine is provided with multiple joints 1, and multiple joints 2 are connected to the thermocouple wires. After the other end of the thermocouple wire is welded to the steel plate, the experimenter inserts the plug 4 into the slot 3 to perform a thermal simulation on the first steel plate. At the same time, the experimenter welds the second steel plate to the thermocouple wire and connects the joint 2 to the thermocouple wire. After the thermal simulation of the first steel plate is completed, the joint 1 and the joint 2 are separated to complete the thermal simulation of the first steel plate. Afterwards, the steel plate with the thermocouple wires welded and the joint 2 with the thermocouple wires connected are quickly connected to the joint 1 on the thermal simulation test machine and a thermal simulation is performed. By setting the joint 1 and the joint 2, the experimenter can quickly connect the steel plate to the thermal simulation test machine, which can improve the experimental efficiency and the efficiency of the use of the thermal simulation test machine, thereby meeting the requirements of fast or large-scale thermal simulation processes.

[0024] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and concept of the present invention, which should be covered by the protection scope of the present invention.
