Abstract
Description
Technical Field
[0001] This invention generally relates to the field of dew point meters, and specifically to an output interface for a dew point meter. Background Technology
[0002] A dew point meter is an instrument that accurately measures the moisture content in a gas. Its core function is to determine the humidity level of a gas by detecting its state at its dew point temperature. Dew point meters play an indispensable role in various industrial production fields, such as monitoring insulation gases in transformers in the power industry, controlling the purity of reaction gases in the chemical industry, and regulating cabin environments in the aerospace industry. Its measurement accuracy directly affects the safety of the production process, the normal operation of equipment, and the quality of the final product, making it a crucial testing device for ensuring the stable operation of industrial systems.
[0003] In the operating system of a dew point meter, the output interface is the core component for transmitting electrical signals between the instrument and external devices. Its connection stability directly affects the accuracy and transmission efficiency of the measurement data. In existing technology, a typical output interface structure mainly consists of a threaded seat and a knob: the threaded seat is fixedly connected to the dew point meter body, and its inner wall has internal threads; the knob's outer wall has corresponding external threads, achieving a detachable connection with the threaded seat through threaded engagement. The wiring method involves winding the transmission line around a specific area of the knob. As the knob is screwed into the threaded seat, the wound line moves synchronously with the knob, ultimately achieving an electrical connection between the two ends of the line and the dew point meter body and the external device respectively through the tightness of the threaded connection.
[0004] However, this structure has a significant reliability flaw: the winding state of the wire depends entirely on the degree of knob rotation, and there is no direct indicator of the wire winding tightness during the threaded engagement between the knob and the threaded seat. Operators can only infer the connection status by the feel of the knob or the number of turns of the thread, making it difficult to accurately determine whether the wire is securely wound. This often results in loosely wound wires in actual use, causing poor electrical contact, manifesting as signal transmission interruptions, data fluctuations, and other connection problems. On the other hand, excessively rotating the knob to achieve a secure connection may lead to excessive stretching or compression of the wire, causing damage to the insulation layer or even breakage of internal wires, further affecting the lifespan and safety of the output interface. Summary of the Invention
[0005] In view of the problems existing in the prior art, the present invention provides an output interface for a dew point meter, comprising: a threaded seat fixed to the back of the dew point meter body and electrically connected to an output unit inside the dew point meter body; a knob threadedly connected to the threaded seat, wherein a reinforcing component communicating with the knob is provided at the end of the knob facing the threaded seat; the reinforcing component includes a ring seat coaxially arranged with the knob and slidably connected along the length direction of the knob; and a spring, one end of which is fixedly connected to the knob and the other end of which is fixedly connected to the ring seat.
[0006] By incorporating the aforementioned technical features, a reinforcing component is added to the end of the traditional knob. The elasticity of the spring is applied to the ring seat to ensure stable connection between the ring seat and the circuit. Furthermore, it can prevent the knob from being over-twisted. The stable connection of the circuit can be ensured solely by the elastic deformation of the spring, thereby guaranteeing the stability and safety of the circuit connection.
[0007] In some embodiments, the knob includes a grip portion, a metal inner tube coaxially fixed within the grip portion, and the metal inner tube being threadedly connected to the threaded seat; and a first conductive ring fixed to the end of the metal inner tube facing the threaded seat. Thus, while the grip portion is threadedly connected to the threaded seat, the circuit can also be connected to the first conductive ring, thereby facilitating circuit conduction to the ring seat area and ensuring stable contact between the ring seat and the circuit.
[0008] In some embodiments, one end of the knob is provided with a slide bar along its length, the slide bar being fixedly connected to the grip portion and abutting against the first conductive ring;
[0009] The slide rod passes through the ring seat and is fixedly connected to the ring seat.
[0010] Therefore, a sliding structure for the ring seat and the knob is provided, which ensures a stable connection between the knob and the ring seat.
[0011] In some embodiments, the spring is sleeved on the slide rod, with one end fixedly connected to the first conductive ring. This not only provides a support area for the spring, allowing its elastic force to act directly on the ring seat area, but also achieves circuit continuity through the mutual fixation of the spring and the first conductive ring.
[0012] In some embodiments, the ring seat includes
[0013] The fixing part is ring-shaped and is slidably connected to the slide rod;
[0014] The second conductive ring is fixed to the end of the fixing part facing the threaded seat, and the other end of the spring is fixed to the second guide ring. This allows the circuit to be guided from the spring to the second conductive ring. When the second conductive ring contacts the circuit, it not only secures the circuit but also stably maintains circuit continuity, minimizing signal interruption.
[0015] In some embodiments, the height of the outer periphery of the second conductive ring is higher than the height of the inner periphery. This forms a bowl-shaped, inverted structure, which effectively limits and gathers the connection area of the circuit. The ring seat not only compresses the circuit winding area but also stably gathers the circuit towards the center, thereby ensuring stable signal connection.
[0016] In some embodiments, the fixing part has a corresponding groove in the annular region on the inner circumference of the second conductive ring. Thus, the second conductive ring is made of metal, and as the ring seat shifts, when it comes into contact with the area where the wire is wrapped, the groove helps the second conductive ring deform, thereby increasing the contact range between the second conductive ring and the wire, further ensuring stable signal transmission.
[0017] In some embodiments, a plurality of dividing grooves are formed along the circumference of the inner periphery of the second conductive ring, thereby forming multiple spring pieces on the inner periphery of the second conductive ring. Thus, the dividing grooves divide the second conductive ring into multiple regions. Under the elastic action of the springs, the second conductive ring undergoes elastic deformation according to the adjacent winding area of the wire, thereby stably contacting the wire and ensuring stable signal propagation.
[0018] In some embodiments, the end of the spring abuts against the periphery of the threaded seat. This provides a double guarantee for stable signal connection; by using a second conductive ring to abut against the threaded seat, stable signal connection to the circuit winding area is achieved.
[0019] It should be understood that the description in the Summary of the Invention is not intended to limit the key or essential features of the embodiments of this disclosure, nor is it intended to restrict the scope of this disclosure. Other features of this disclosure will become readily apparent from the following description. Attached Figure Description

[0026] The preferred embodiments (or implementation methods) of the present invention will now be described in detail with reference to the accompanying drawings.
[0027] The following is for reference. Figures 1-4 This invention describes the output interface of a dew point meter.
[0028] Figure 1 A schematic diagram of the output interface area of a dew point meter according to an embodiment of the present invention is shown. (Reference) Figure 1 As shown, the dew point meter body 1 has multiple interface types. The output interface, as the key channel for establishing a connection between the instrument and external systems, mainly undertakes the function of transmitting measurement data and status information. It can stably transmit the core parameters such as dew point temperature and humidity detected by the instrument in real time to external data recording devices, computer terminals, or automated control systems, providing original evidence for subsequent data storage, analysis, and traceability. At the same time, some output interfaces can also receive control commands from external devices to realize remote control of the dew point meter's operating status, such as starting and stopping measurements, parameter calibration, etc., thereby ensuring the continuity and automation of the dew point monitoring process in industrial production, laboratory testing, and other scenarios, and ensuring the coordinated and efficient operation of the entire monitoring system. One type of interface includes a threaded seat 2 fixed to the back of the dew point meter body 1, and a knob 3 threadedly connected to the threaded seat 2.
[0029] Specifically, this type of interface is provided in multiple sets and is evenly arrayed on the back of the dew point meter body 1 to meet the signal output of multiple devices.
[0030] Figure 2 A schematic diagram of the knob 3 in the output interface of a dew point meter according to an embodiment of this utility model is shown. (Reference) Figure 2As shown, the knob 3 includes a grip portion 31, which can be a cylindrical structure, generally made of a plastic insulating material, which is lightweight while ensuring operational safety. Furthermore, multiple grooves are formed on the periphery of the grip portion 31 to increase the contact area between the hand and the grip portion 31, improving the grip feel and operational efficiency. A metal inner tube 32 is coaxially fixed inside the grip portion 31. The inner wall of the metal inner tube 32 has an internal thread that mates with the threaded seat 2. One end of the metal inner tube 32 is coaxially fixed to a first conductive ring 33 of the same material. When the knob 3 is threadedly connected to the threaded seat 2, the threaded seat 2 enables signal conduction to the conductive ring.
[0031] Figure 3 A schematic diagram of the reinforcement component 4 in the output interface of a dew point meter according to an embodiment of the present invention is shown. (See reference) Figure 2 and Figure 3 As shown, a reinforcing component 4 is fixedly connected to one end of the knob 3. The reinforcing component 4 includes a ring seat 41 coaxially disposed at one end of the knob 3. The ring seat 41 and the knob 3 are connected to each other via a slide rod 42. One end of the slide rod 42 passes through the interior of the knob 3 and is slidably connected to the grip portion 31 of the knob 3. The other end of the slide rod 42 is fixedly connected to the interior of the ring seat 41, thereby realizing the mutual sliding of the ring seat 41 and the knob 3. A spring 43 is sleeved on the slide rod 42. One end of the spring 43 is fixedly connected to the first conductive ring 33, and the other end of the spring 43 extends toward the ring seat 41.
[0032] In some embodiments, at least two slide bars 42 are provided and symmetrically arranged on both sides of the knob 3 to ensure a stable connection between the ring seat 41 and the knob 3.
[0033] Figure 4 An exploded view of the ring seat 41 structure in the output interface of a dew point meter according to an embodiment of the present invention is shown. (See reference) Figure 4 As shown, the ring seat 41 includes an annular fixing part 411, which is coaxially arranged with the knob 3. It is generally made of plastic material to ensure a lightweight structure and reduce the driving pressure of the spring 43. A second conductive ring 412 is provided at the end of the ring seat 41 opposite to the knob 3. The second conductive ring 412 is coaxially arranged with the ring seat 41, and the other end of the spring 43 passes through the fixing part 411 and is fixed to the second conductive ring 412. When the knob 3 is threadedly connected to the threaded seat 2, the signal can be transmitted sequentially through the threaded seat 2 to the metal inner tube 32, the first conductive ring 33, the spring 43, and the second conductive ring 412.
[0034] In some embodiments, the annular height of the outer periphery of the second conductive ring 412 is higher than the annular height of the inner periphery of the second conductive ring 412, so that the second conductive ring 412 forms an inverted bowl-shaped structure. When the knob 3 and the threaded seat 2 are threaded together, the ring seat 41 will preferentially contact the winding area of the wire. The structural shape of the second conductive ring 412 itself plays a role in converging the conductive winding area towards the center, thereby ensuring the stability of the connection between the winding area of the wire and the threaded seat 2.
[0035] In some embodiments, the fixing part 411 of the ring seat 41 has an annular groove 413 on the inner circumferential side of the second conductive ring 412, so that the annular area on the inner circumferential side of the second conductive ring 412 lacks support. When the ring seat 41 stably abuts against the winding area of the wire, the second conductive ring 412 is made of metal and has its own ductility. As the second conductive ring 412 abuts against the wire, it deforms and increases the contact range between the second conductive ring 412 and the wire, ensuring the stability and security of signal communication.
[0036] In some embodiments, the second conductive ring 412 is provided with a plurality of dividing grooves evenly distributed from the center to the periphery, so that a plurality of spring pieces 414 are formed in the inner annular region of the second conductive ring 412. When the second conductive ring 412 comes into contact with the wire winding region, each spring piece 414 is more adapted to the shape of the wire in the corresponding region, thereby increasing the contact range between the wire and the spring piece 414 more effectively and further ensuring stable signal connection.
[0037] Furthermore, when the knob 3 is threadedly connected to the threaded seat 2, the length of each spring piece 414 is sufficient to abut against the periphery of the threaded seat 2, further reducing the signal transmission path and ensuring stable signal transmission.
[0038] When the dew point meter body 1 transmits signals to other devices, the wire can be wound around the periphery of the threaded seat 2. Then, through the threaded connection between the knob 3 and the threaded seat 2, the ring seat 41 is moved to displace the area where the wire is wound. As the knob 3 continues to rotate, the ring seat 41 comes into contact with the area where the wire is wound. Through the elastic force of the spring 43, the ring seat 41 makes stable contact with the area where the wire is wound. The counterforce of the spring 43 also increases the friction between the knob 3 and the threaded seat 2, thereby restricting the free rotation of the knob 3 and ensuring the stability of the connection between the knob 3 and the threaded seat 2. Moreover, the bowl-shaped structure of the second conductive ring 412 has a gathering effect on the connection area of the wire, ensuring the firmness of the wire connection area. Furthermore, as the spring piece 414 abuts against the area where the wire is wound, the contact range between the wire and the second conductive ring 412 is increased, ensuring stable signal transmission.
