Description

Technical Field

[0001] This invention generally relates to the field of dew point meters, and more specifically to a hub device for a dew point meter. Background Technology

[0002] A dew point meter is an instrument used to measure the moisture content in a gas. Its core function is to determine the humidity level of a gas by detecting its dew point temperature. It is widely used in many fields such as chemical engineering, power generation, meteorology, and pharmaceuticals. It is of great significance for ensuring the stability of production processes, the normal operation of equipment, and product quality.

[0003] During the use of a dew point meter, various circuits are often required to work together to achieve its various functions, including power cords, USB communication cables, LAN communication cables, and PRT expansion devices. These circuits and devices are essential components for ensuring the normal operation of the dew point meter and enabling data transmission and power supply.

[0004] Furthermore, in existing technologies, dew point meters typically lack dedicated storage boxes or organizers for these circuits and related structures. This results in a scattered distribution of circuits during practical applications, which not only easily become tangled and knotted, affecting their lifespan and normal function, but also create a cluttered environment around the dew point meter, hindering operation and management. The chaotic wiring can even lead to safety hazards such as misoperation, causing numerous inconveniences in the use of the dew point meter. Summary of the Invention

[0005] In view of the problems existing in the prior art, the present invention provides a hub device for a dew point meter, comprising: a fixing plate, which includes a base plate and a protective plate, bent and fixed on opposite sides of the base plate; and further comprising a plurality of connectors, which are disposed on the inner sidewall of the fixing plate and fixed to the base plate, and are used to be plugged into the PRT output interface on the back of the dew point meter body, wherein the position of the connector corresponds to the position of the PRT output interface of the dew point meter body.

[0006] With the aforementioned technical features, the protrusion of the connector provides a supporting carrier for the winding of the wire. Moreover, through the mutual plugging of the connector and the PRT output interface, it plays a role in shielding and protecting the rear interface of the dew point meter body. This means that the fixing plate not only shields the area where the wire is wound, but also further shields and protects the interface on the back of the dew point meter body, making the dew point meter body more convenient to carry.

[0007] In some embodiments, the connector is a tube, the inner diameter of which is smaller than the outline diameter of the PRT output interface, and an expansion groove is formed at the end of the connector along its length. Thus, through the mutual insertion of the connector and the PRT output interface, the slightly smaller diameter of the connector allows for increased friction with the PRT output interface through deformation, increasing the tightness of the connection and ensuring the stability of the wire binding during the displacement of the dew point meter body.

[0008] In some embodiments, the inner wall of the connector is provided with a limiting ridge along its circumference. Thus, the limiting ridge is located on the inner wall of the connector, and during the process of the connector and the PRT output interface being plugged in, the limiting ridge is engaged at the edge of the PRT output interface knob, preventing the PRT output interface from disengaging from the connector, and ensuring the tightness of the connection between the hub and the dew point meter body.

[0009] In some embodiments, a protrusion is fixed to the side of the substrate opposite to the connector. This protrusion increases the winding space for the wire, thereby making full use of the space on the back side of the fixing plate, and also further increases the overall strength of the fixing plate.

[0010] In some embodiments, a limiting plate is fixedly attached to the edge of the convex plate along its length. Thus, the limiting plate, located at the edge of the convex plate, limits the wire wound on the convex plate, thereby ensuring the firmness of the connection between the wire and the convex plate and preventing the wire from loosening or detaching.

[0011] In some embodiments, the edge of the guard plate is provided with a plurality of first notches spaced apart along its length for opening the wire. Thus, the first notches limit the end of the wire, thereby ensuring the tightness of the wire winding, and also provide auxiliary positioning for the wire, making it less likely to entangle with the surrounding wire.

[0012] In some embodiments, the edge of the guard plate has a second notch between adjacent first notches, and the length of the second notch is greater than the length of the first notch. Therefore, a suitable wire winding area can be selected according to the length of the wire, reducing excess wire at the wire end, ensuring the tightness of the wire winding, and the wire winding also acts as a shield for the wire wound at the protruding plate, achieving the functions of wire separation and management.

[0013] In some embodiments, a receiving groove is provided at the root of the second notch. Thus, the receiving groove serves to accommodate the winding of the wire, allowing individual wires to be wound together in the area of ​​the receiving groove, resulting in more concentrated wire storage.

[0014] In some embodiments, each of the protective plates has a magnet embedded along its length at its edge for magnetically attracting the housing of the dew point meter. This positions the edge of the fixing plate, improving the tightness of the connection between the fixing plate and the dew point meter body.

[0015] 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

[0022] The preferred embodiments (or implementation methods) of the present invention will now be described in detail with reference to the accompanying drawings.

[0023] The following is for reference. Figures 1-4 This invention describes a hub device for a dew point meter.

[0024] Figure 1 A schematic diagram of the structure of the back region of the dew point meter in a hub device according to an embodiment of the present invention is shown. (Reference) Figure 1 As shown, the present embodiment provides a hub device for a dew point meter, which is fixed to the PRT output interface 11 area at the rear of the dew point meter body 1, and specifically includes a fixing plate 2 and multiple plugs 3 fixed to one side of the fixing plate 2.

[0025] Figure 2A schematic diagram of the overall structure of a hub device for a dew point meter according to an embodiment of the present invention is shown. (Reference) Figure 2 As shown, the fixing plate 2 is a plate covering a portion of the back of the dew point meter body 1. Specifically, it includes a vertical base plate 21, which can be a rectangular plate. The upper and lower edges of the base plate are bent towards the dew point meter body 1 and have protective plates 22. The side of the base plate 21 facing the dew point meter body 1 is also provided with multiple connectors 3 for connecting and cooperating with the PRT output interface 11 on the back of the dew point meter body 1.

[0026] Specifically, there can be four connectors 3, located at the four corners of the substrate 21, corresponding one-to-one with the positions of the PRT output interfaces 11. This improves the stability of the connection between the hub and the dew point meter body 1 after the connectors 3 are plugged into each other. Alternatively, the number of connectors 3 can correspond to the number of PRT output interfaces 11. When the connectors are plugged into each other, the multiple support points of the connectors 3 greatly improve the stability of the hub.

[0027] On the one hand, the number of connectors 3 directly affects the support points for cable winding. The gap between adjacent connectors 3 can accommodate the winding of multiple cables simultaneously, without affecting the mutual insertion of connectors 3 and PRT output interface 11, while leaving enough space for cable winding. Moreover, after the cable collection device and the dew point meter body 1 are fixed together, the fixing plate 2 shields the interface area, and the cable is placed between the dew point meter body 1 and the fixing plate 2, which reduces the contact between the cable and the external environment and ensures the integrity of the cable storage.

[0028] Figure 3 A schematic diagram of the connector 3 in the hub of a dew point meter according to an embodiment of the present invention is shown. (See reference) Figure 3 As shown, the connector 3 is a cylindrical tube with an inner wall diameter slightly smaller than the outer contour diameter of the PRT output interface 11. The port area of ​​the connector 3 has a strip-shaped expansion groove 31 along the length of the connector 3. When the connector 3 and the PRT output interface 11 are plugged into each other, the connector 3 covers the outer contour of the PRT output interface 11, which increases the friction between the connector 3 and the PRT output interface 11 and improves the stability of the plugging between the connector 3 and the PRT output interface 11.

[0029] In some embodiments, each connector 3 may have two expansion slots 31, which are symmetrically arranged on both sides of the connector 3. This can increase the deformation range of the connector 3 in the plugging state and avoid the deformation area of ​​the connector 3 being too concentrated when there is only one expansion slot 31, which would affect the service life of the connector 3.

[0030] Furthermore, a ring-shaped limiting ridge 32 is formed along the circumference of the inner wall of the connector 3. The cross-section of the limiting ridge 32 is arc-shaped, which reduces the risk of damage to the PRT output interface 11 or the connector 3 structure due to excessive local stress when the connector 3 is plugged into the PRT output interface 11. It also serves as a guide, improving the operator's efficiency. After the connector 3 is plugged into the PRT output interface 11, the limiting ridge 32 is located at the edge of the knob of the PRT output interface 11, preventing the connector 3 from disengaging from the PRT output interface 11 and ensuring the stability of the connection between the connector 3 and the PRT output interface 11.

[0031] Figure 4 A schematic diagram of the back side structure of the fixing plate 2 in the hub device of a dew point meter according to an embodiment of the present invention is shown. (See reference) Figure 4 As shown, a protruding plate 4 is horizontally fixed along the length of the substrate 21 on the side opposite to the connector 3. This not only increases the support strength of the substrate 21, but also allows the wire to be wound on the protruding plate 4, increasing the fixing area of ​​the wire.

[0032] Furthermore, a limiting plate 5 is connected to the edge of the protruding plate 4 along the length direction of the protruding plate 4. The cross-section of the limiting plate 5 can be circular, rectangular, or polygonal, as long as its cross-sectional size is larger than the edge size of the protruding plate 4, so as to limit the wire wound on the protruding plate 4 and ensure the stability of the wire wound on the protruding plate 4.

[0033] Furthermore, multiple first notches 221 are provided along the length of the guard plate 22 at its edge. Adjacent first notches 221 are spaced apart, which not only provides a locking area for the wire end, but also allows the wire to be wound around the first notch 221, indirectly limiting and positioning the wire. Moreover, the winding of the wire on the convex plate 4 is horizontal, while the winding of the wire at the first notch 221 is vertical. The vertical winding method of multiple wires not only makes it easy to separate different wires, but also provides mutual limiting protection, ensuring the stability of the wire and the cable collection device.

[0034] Furthermore, a second notch 222 is provided at the edge of each guard plate 22 between adjacent first notches 221. The length of the second notch 222 is greater than the length of the first notch 221, so that the operator can select the appropriate winding area and position according to the length of the wire. Moreover, since the wire will have a slack after winding, the operator can select the appropriate notch for fixing based on winding experience, thereby reducing the slack at the end of the wire and improving the overall stability of the wire fixing.

[0035] Furthermore, a receiving groove 223 is provided at the end of the second notch 222. The opening of the receiving groove 223 increases the storage space for the wire and improves the gathering effect of the wire. Moreover, due to the reasonable arrangement of the first notch 221 and the second notch 222, the opening space of the receiving groove 223 is increased, and the mutual interference with the surrounding structure is reduced.

[0036] In some embodiments, the receiving groove 223 may be a circular hole to reduce the abrasion of the wire by its sharp internal edges, thereby improving the safety and stability of the wire winding.

[0037] refer to Figure 2 As shown, each guard plate 22 has multiple magnets 6 embedded along its edge. When the cable management device and the PRT output interface 11 are plugged into each other, the edge of the guard plate 22 is attracted to the housing of the dew point meter body 1, thereby increasing the stability of the dew point meter body 1 and the cable management device. Moreover, since most of the wires are located in the first notch 221, the second notch 222, and the receiving groove 223, they will not affect the magnetic fixation of the edge of the guard plate 22 and the dew point meter body 1.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.
