Description

Technical Field

[0001] The utility model relates to the technical field of temperature sensing cables, in particular to a digital temperature sensing cable. Background Art

[0002] Temperature sensing cable is a sensor material used to measure temperature. It is widely used in modern industrial production. It consists of a high-temperature resistant metal or alloy wire and one or more heat conductors. The temperature of the medium is inferred by measuring the voltage difference between the wires, thereby realizing temperature monitoring and measurement. This principle is based on the thermoelectric effect and can be used for temperature measurement and control in various industrial and environmental applications.

[0003] However, in actual use, the wires are generally connected to the internal components of the signal processor, and the wires are easily affected by external forces, so that the wires are pulled by the force and have poor contact with the signal processor, thereby affecting information transmission and cable operation.

Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] The utility model provides Figure 1 , Figure 3 and Figure 4As shown, a digital temperature sensing cable comprises a processor 1 and a connecting tube 2, a connecting tube 2 is provided at the bottom of the processor 1, a rotating sleeve 3 is provided on the outer wall of the connecting tube 2, a thread groove 4 is provided at the inner wall of the rotating sleeve 3 corresponding to the outer wall of the connecting tube 2, a through groove 5 is provided at the lower part of the outer wall of the connecting tube 2, a slope 6 is provided at the lower part of the inner wall of the connecting tube 2, an extrusion ring 7 is provided at the lower part of the inner wall of the rotating sleeve 3, a wire 8 is provided inside the connecting tube 2, a mounting block 9 is provided on the outer wall of the processor 1, and the rotating sleeve 3 is threadedly connected to the connecting tube 2;

[0021] The operation is as follows: first, the staff connects the wire 8 to the inside of the processor 1, and then manually rotates the rotating sleeve 3. At this time, the extrusion ring 7 applies pressure to the lower part of the outer wall of the connecting tube 2, and at the same time, the through groove 5 is forced to narrow, and the slope 6 is forced to move closer to the center, so as to clamp the outer wall of the wire 8. By setting the connecting tube 2 and the rotating sleeve 3, in actual use, the staff can rotate the rotating sleeve 3 to make the extrusion ring 7 apply pressure to the connecting tube 2, so that the connecting tube 2 clamps and fixes the wire 8, so that the processor 1 and the wire 8 are more tightly connected. After the wire 8 is subjected to external force, it will not be easily separated from the internal components of the processor 1, thereby enhancing the applicability and risk resistance of the product;

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, there are two mounting blocks 9, which are symmetrically distributed along the central axis of the processor 1, and the through grooves 5 are distributed in an array with the outer wall of the connecting tube 2. The outer wall of the processor 1 is fixedly connected to the connecting tube 2, the inner diameter of the lower part of the connecting tube 2 is smaller than the inner diameter of the upper part, and the inner diameter of the extrusion ring 7 is smaller than the outer diameter of the connecting tube 2;

[0023] The specific operation is as follows. When the staff needs to install the processor 1, they can connect the mounting block 9 to the fixed location by bolts. When the wire 8 needs to be removed, they can rotate the rotating sleeve 3 in the opposite direction. By setting the threaded groove 4, the through groove 5 and the slope 6, the staff can rotate the rotating sleeve 3 so that the slope 6 is moved closer to the center due to the change of the through groove 5, thereby completing the clamping of the wire 8. The mounting block 9 facilitates the staff to install the processor 1.

[0024] Working principle of this utility model:

[0025] Refer to the instruction manual Figures 1 to 4 When using the utility model, the staff first connects the wire 8 to the inside of the processor 1, and then manually rotates the rotating sleeve 3. At this time, the extrusion ring 7 applies pressure to the lower part of the outer wall of the connecting tube 2, and at the same time, the through groove 5 is forced to narrow, and the slope 6 is forced to move closer to the center to clamp the outer wall of the wire 8. When the staff needs to install the processor 1, the mounting block 9 is connected to the fixed location by bolts. When the wire 8 needs to be removed, the rotating sleeve 3 is rotated in the opposite direction. The above is the working principle.
