DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION
FIG. 1 illustrates a detector, such as a gaseous ionizing radiation detector, including a housing and an interface structure for conducting and transporting fluids according to one embodiment of the present disclosure.
The interface structure is used for transmitting fluid into the detector shell and transmitting current to the detector. As shown in fig. 1, the interface structure for conducting and transferring fluids is configured to allow the transmission of electrical signals and fluids.
In one embodiment, the interface structure comprises: an insulating assembly and a transmission member.
For example, as shown in fig. 3, according to an embodiment of the present disclosure, the insulation assembly is formed of an insulation material, and may include a receiving section 205, the receiving section 205 having a hollow structure defining a receiving space. The receiving section 205 may be a separate component, however, may also be part of the insulating assembly. The insulation assembly may include only the receiving segment 205, or may include other components. The receiving section 205 may be, for example, a cylindrical tube, such as a cylindrical insulating tube. In one embodiment, the receiving segment 205 may be an insulating tube of other shapes, such as an oval-shaped insulating tube, for transporting fluids. In one embodiment, the containment segment 205 may be a rectangular insulating tube for transporting fluids. The fluid comprises air, liquid, or a mixture of air and liquid.
In one embodiment, the transmission assembly of the interface assembly includes a transmission member 206, the transmission member 206 being formed of an electrically conductive material and having a hollow structure defining first flow-inducing apertures 2061, the first flow-inducing apertures 2061 allowing fluid to flow therethrough. The transmission assembly further comprises an electrically conductive piece 208, a first end of said electrically conductive piece 208 being fixedly connected and electrically connected to said transmission member 206. The transmission member 206 is for electrical conductivity and may be formed of an electrically conductive material, for example, the transmission member 206 may be a metal round tube. In one embodiment, the conductive member 208 may be a wire or a metal wire, etc.
In this embodiment, the transfer member 206 is located in the receiving space of the receiving section 205 of the insulation assembly, the first diversion holes 2061 of the transfer member 206 are in fluid communication with the receiving space, and a fluid seal is formed between the outer surface of the transfer member 206 and the inner surface of the receiving section 205 of the insulation assembly. The fluid communication of the first flow-directing apertures 2061 of the transfer member 206 with the receiving space refers to the fluid communication between the first flow-directing apertures 2061 of the transfer member 206 and the portion of the receiving space defined by the fluid seal between the outer surface of the transfer member 206 and the inner surface of the receiving section 205 of the insulation assembly.
The conductors 208 extend from the transmission member 206 out of the interface structure within the receiving space of the receiving section 205 of the insulating assembly. The conductors 208 extending out of the interface structure may be electrically connected or fixedly connected to other components. For example, conductive member 208 may be coupled to a detector device.
In one embodiment, the transmission member 206 may, for example, have a cylindrical shape, such as a conductive metal round tube. The transmission member 206 of the conductive metal circular tube is arranged in the cylindrical accommodating section 205, the size of the transmission member 206 can be set to make the outer surface of the transmission member 206 fit with the inner surface of the accommodating section 205, the accommodating section 205 can be heated during installation to increase the thermal expansion size of the accommodating section 205, and then after the transmission member 206 is arranged in the accommodating section 205, the accommodating section 205 and the transmission member 206 form a tight fit after the normal temperature is recovered. In this embodiment, the tight fit between the containment section 205 and the transmission member 206 causes a seal to be formed between the outer surface of the transmission member 206 and the inner surface of the containment section 205.
In another embodiment, the transmission member 206 of a conductive metal round tube is disposed within the cylindrical receiving section 205, the transmission member 206 may be sized such that a gap is formed between the outer surface of the transmission member 206 and the inner surface of the receiving section 205, and a sealing ring 223 is disposed between the outer surface of the transmission member 206 and the inner surface of the receiving section 205 such that a seal is formed between the outer surface of the transmission member 206 and the inner surface of the receiving section 205.
The seal between the outer surface of the transfer member 206 and the inner surface of the containment section 205 is such that fluid can only enter the space defined by the containment section 205 from the first diversion aperture 2061 of the transfer member 206 and fluid cannot enter or exit the space defined by the containment section 205 from between the outer surface of the transfer member 206 and the inner surface of the containment section 205.
In one embodiment, the insulation assembly may further include a positioning guide section 211 provided with at least one second guide hole 2111, and the receiving section 205 is connected to the positioning guide section 211 such that the receiving space is in fluid communication with the at least one second guide hole 2111.
The positioning flow guide section 211 further comprises a positioning hole 2113. The conductive piece 208 may extend from the positioning hole 2113 so that the second end of the conductive piece 208 can be fixed by a component other than the positioning hole 2113. The first end and the second end of the conductive member 208 may be fixed, and a portion between the first end and the second end of the conductive member 208 may be positioned by the positioning hole 2113. The positioning hole 2113 and the second guide hole 2111 are different holes of the guide section.
In one embodiment, as shown in fig. 2, the cross-sectional view and the plan view of the positioning guide section 211 show that the positioning hole 2113 may be located at the center of the positioning guide section 211, and the second guide holes 2111 may be located at both sides of the positioning hole 2113. In other embodiments, the second flow guiding holes 2111 may be three, four, five or more, or may be a plurality of closely-spaced holes. The arrangement of the second diversion holes 2111 may also be random or regularly arranged along a circular path.
In one embodiment, the positioning guide section 211 has an axisymmetric structure, and the positioning hole 2113 is disposed at the center of the axisymmetric structure. Such a configuration may secure the electrical conductor in the center of the flow guide section and insulation assembly.
In the embodiment shown in fig. 2, the positioning flow guide section 211 may further include a tapered hole 2112 (shown in cross-section) having a length greater than the length of the positioning hole 2113. Tapered hole 2112 may serve as a guide structure for guiding conductor 208 through positioning hole 2113 for positioning.
In one embodiment, the outer peripheral surface of the guide structure has a reduced-size portion, such as the left end shown in fig. 2, having a stepped shape. In another embodiment, the outer surface of the guide structure has a frustoconical shape. The stepped shape or the frusto-conical shape may serve as a location for assembly. In particular, when assembling the insulating assembly, for example assembling the insulating assembly into a hole, the stepped shape or the frustoconical shape is such that the insulating assembly cannot pass through the hole, but is blocked by a corresponding step or bevel of the hole.
In one embodiment, the receiving section 205 and the positioning guide section 211 are separate components of an insulation assembly, the receiving section 205 and the positioning guide section 211 being joined (e.g., bonded, welded, etc.) to form the insulation assembly; however, in another embodiment, the insulation assembly is unitary, and the containment section 205 and the positioning guide section 211 are different portions of the insulation assembly.
In one embodiment, the insulating member is formed of a resilient material, such as polyimide, polytetrafluoroethylene, or polyetheretherketone. That is, the receiving section 205 and the positioning guide section 211 may be formed using an insulating organic material. The insulating organic material is insulating and easy to form, for example, by molding to form an integrated insulating member or separately forming the receiving section 205 and the positioning guide section 211, so that the fabrication is simple. Furthermore, the organic material may have a certain elasticity, i.e. a certain deformation of the receiving section 205 may occur in case of pressure, which is advantageous at the time of assembly, e.g. a press fit may be achieved.
In one embodiment, a first end (e.g., the right end as viewed in fig. 1) of conductor 208 is coupled to conductor 208 by passing through mounting hole 204 in a sidewall of transmission member 206. For example, the conductive member 208 has a certain strength, and the first end is formed in a hook shape, so that an electrical connection can be formed on the mounting hole 204 on the sidewall of the transmission member 206, and the connection facilitates the mounting. In one embodiment, a bolt may be provided on a sidewall of the transmission member 206, and the first end of the conductor 208 may be attached to the bolt.
The conductive member 208 further includes a tension spring portion 207 in the receiving space. As shown in fig. 1, the extension spring portion 207 is within the space defined by the receiving section 205. The dimensions of the conductive element 208 and other components may change due to temperature changes, for example, the conductive element 208 is a conductive metal, the insulating element is a polymer insulating material, and the expansion coefficients are different from each other, so that the increase in size due to temperature rise is different, the conductive element 208 and other components have disproportionate dimensional changes, and the two ends of the conductive element 208 are fixedly connected, so that the conductive element 208 is subjected to a tensile force. In this embodiment, the tension spring portion 207 of the conductive element 208 can be extended and retracted, so as to eliminate the disproportionate stretching effect on the conductive element 208 caused by the dimensional changes of the conductive element 208 and other components during the temperature variation process, and avoid the conductive element 208 being pulled apart or the end of the conductive element 208 being loose.
The conductor-provided tension spring portion 207 may also allow the first end of the conductor 208 to protrude outside the receiving space defined by the receiving section 205 by extension of the tension spring portion 207 during installation or when replacing the transmission member 206, the first end of the conductor 208 is passed through the mounting hole 204 of the transmission member 206 outside the receiving section 205 to obtain electrical connection of the conductor 208 to the transmission member 206, and the tension spring portion 207 can be retracted to pull the transmission member 206 back into the receiving space defined by the receiving section 205. Such a design allows for convenient and easy assembly of the transmission and insulation components.
In one embodiment, positioning holes 2113 of positioning guide section 211 allow conductor 208 to move within positioning hole 2113. In one embodiment, locating hole 2113 may be sized similar to the size of conductive member 208 and slightly larger than the size of conductive member 208. For example, the aperture of the positioning hole 2113 is in the range of tens of micrometers to several millimeters, the accuracy of the positioning hole 2113 at the position of the central axis of the detector housing can be controlled in the range of hundreds of micrometers to tens of micrometers, the accuracy can be realized by common machining equipment, and the conductive member 208 can be accurately positioned after penetrating through the conical hole to be centrally positioned. Locating hole 2113 may thus locate a middle portion of conductive member 208 such that conductive member 208 (e.g., conductive member 208 is a conductive wire) does not sag, while allowing movement of conductive member 208 relative to locating hole 2113 as temperature changes.
The interface structure of the present disclosure can realize fluid communication and electrical connection between the interface structure and the device to be connected only by providing one through hole or channel for the device to be connected, thereby reducing the number of openings; the further positioning of the conductive member allows devices such as probes to operate more stably.
Embodiments of the present disclosure also provide a detector device, including: the above-mentioned interface structure; and a housing. The housing includes a first support plate 202 and a second support plate 210 disposed opposite to each other to define an inner space. The first support plate 202 includes a mounting through hole 2022. The interface structure is mounted within the mounting through-hole 2022 of the mounting portion. A fluid seal is formed between the outer surface of the insulating component of the interface structure and the inner surface of the mounting through-hole 2022, the at least one second baffle hole 2111 of the interface structure is in fluid communication with the interior space defined by the housing, and the second end of the electrical conductor of the interface structure is fixedly attached to the second support plate 210 of the housing.
The housing of the probe may for example be cylindrical, however, the probe housing may be other shapes, such as rectangular.
In one embodiment, the mounting through hole 2022 of the mounting portion has a step or slope such that the stepped or truncated cone shape of the positioning guide section 211 of the insulating assembly mates with the step or slope within the mounting through hole 2022 to axially position the insulating assembly. With such a structure, when the interface structure is assembled to the mounting through-hole 2022, the interface structure may be positioned against a step or a slope of the mounting through-hole 2022 without passing through the mounting through-hole 2022.
In one embodiment, the first support plate 202 includes a mounting portion 2021, the mounting portion 2021 protrudes from the first support plate 202, and the mounting through-hole 2022 is disposed within the mounting portion 2021.

The externally threaded ring connector 203 may be coupled to a surface of the mounting portion 2021 while the receiving section 205 of the interface structure may be positioned.
In one embodiment, the receiving section 205 of the insulating assembly can be deformed by being pressed by the inner tapered wedge 204, and the inner surface of the receiving section 205 of the insulating assembly presses against the outer surface of the transmission member 206. This is an advantageous configuration when the ferrule assembly is threaded to the mounting portion 2021, as in fig. 1, the ferrule assembly is moved to the left, the internal tapered wedge 204 presses against the receiving section 205 such that the receiving section 205 is deformed by the pressing, thereby causing contact between the receiving section 205 and the transmission member 206 to be compressed, the receiving section 205 is secured by the internal tapered wedge 204, and the transmission member 206 is secured by the receiving section 205 such that the interface structure is further secured, and the connection between the interface structure and the mounting portion 2021 is further strengthened.
