Description

Technical Field

[0001] This utility model belongs to the field of PXIe measuring instruments, specifically relating to a multi-slot embedded PXIe chassis that facilitates board installation. Background Technology

[0002] In today's rapidly developing electronic information technology landscape, the PXIe (PCIe Extensions for Instrumentation) signal processing platform is an electronic measurement instrument used in the fields of electronics and communication technology. It is an extension device of the PXI signal processing platform based on PCI Express (PCIe) technology. The PXIe signal processing platform chassis houses the main circuit board and multiple daughter cards, which are plugged into the main circuit board. As a core component of high-performance test and measurement systems, the rational utilization of the chassis's internal space and the reliability and durability of its components are key factors affecting the overall system performance. The PXIe chassis typically contains multiple plug-in components (such as expansion cards) for expanding system functionality. These plug-in components transmit data and receive power from the motherboard or backplane within the chassis via precise electrical connections.

[0003] However, traditional PXIe chassis often suffer from insufficient space utilization in their design. The mounting positions of plug-in components are usually fixed, making it difficult to flexibly adjust them according to actual application needs. This not only limits the compatibility of different sizes and types of plug-in components within the chassis, but may also lead to wasted internal space, especially when facing complex and ever-changing test and measurement requirements.

[0004] In addition, the connection between the slot of the plug-in component and the control board is usually made by direct soldering. When the plug-in component is frequently plugged in and out or is affected by external factors such as vibration and impact, problems such as loose connection, signal attenuation or even open circuit may occur, which seriously affects the service life of the plug-in component and the control board slot and the stability of the system. Utility Model Content

[0005] The purpose of this invention is to provide a multi-slot embedded PXIe chassis that facilitates board installation.

[0006] To achieve the above objectives, this utility model provides a multi-slot embedded PXIe chassis for easy board installation, used to install plug-in components. The chassis includes a housing, the housing having a mounting cavity, and a partition inside the housing dividing the mounting cavity into a first mounting cavity and a second mounting cavity.

[0007] A support assembly is provided at the bottom of the plug-in component, including at least two sets of first brackets and at least one second bracket with both ends respectively mounted on the first brackets. The second bracket includes a guide for mounting the plug-in component, and the plug-in component is adjusted to the mounting position in the first mounting cavity through the second bracket.

[0008] A plug-in assembly is provided on the plug-in side of the plug-in component. The plug-in assembly includes several plug slots that mate with the pins on the plug-in component. A control board perpendicular to the plug-in component is flexibly electrically connected to the plug slots.

[0009] The locking assembly includes a locking rod rotatably disposed on the opening side of the first mounting cavity. When the locking rod is in a clearance state, it allows the insert to be freely pushed in and pushed out of the first mounting cavity. When the locking rod is against the insert, it is in a locking state that restricts the insert from being freely pushed in and pushed out of the first mounting cavity.

[0010] In some embodiments, the guide portion is a guide groove formed in the second bracket, through which the insertion / removal member is freely pushed into or pushed out of the first mounting cavity.

[0011] In some embodiments, the inner side of the guide groove is provided with at least one set of elastic protrusions for clamping and positioning the plug-in component.

[0012] In some embodiments, the ends of the second bracket that contact the first bracket are respectively provided with countersunk holes, and the first bracket is provided with a plurality of threaded holes at equal intervals.

[0015] In some embodiments, the insert panel is further provided with a sleeve, through which the fastening screw is connected to the threaded hole.

[0016] In some embodiments, the locking rod has cranks connected to both ends, and torsion springs are sleeved on the cranks. The locking rod includes a locking state that abuts against the insert to restrict the insert from being freely pushed in and out of the first mounting cavity, and an unlocking state that separates the insert from the insert to allow the insert to be freely pushed in and out of the first mounting cavity. It also includes a torsion spring disposed at the end of the locking rod to maintain the locking state.

[0017] In some embodiments, at least one set of cooling fans is installed in the first mounting cavity, and a through hole is provided for the cooling fans to exchange airflow; a sensor bracket is also provided in the first mounting cavity, and a sensor is provided on the sensor bracket, and the sensor is electrically connected to the control board.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Because the mounting positions of plug-in components are usually fixed, it is difficult to flexibly adjust them according to actual application requirements. This not only limits the compatibility of different sizes and types of plug-in components within the chassis, but may also lead to wasted internal chassis space. This limitation is particularly evident when facing complex and ever-changing test and measurement needs. In addition, the connection between the plug-in component slot and the control board is usually achieved through direct soldering. This connection method is prone to problems such as loosening, signal attenuation, or even open circuits when the plug-in component is frequently inserted and removed or affected by external factors such as vibration and impact. This seriously affects the service life of the plug-in component and the control board slot, as well as the stability of the system.

[0030] Therefore, this application provides a multi-slot embedded PXIe chassis that facilitates board installation.

[0031] Figure 1 This is a structural schematic diagram of a multi-slot embedded PXIe chassis that facilitates board installation, provided by an embodiment of this utility model.

[0032] Figure 2 This is a top view of a multi-slot embedded PXIe chassis that facilitates board installation, according to an embodiment of the present invention.

[0033] like Figures 1 to 2As shown, this embodiment provides a multi-slot embedded PXIe chassis for easy board installation, used to install plug-in components. The chassis includes a housing 10, which has a mounting cavity. A partition 12 is provided inside the housing 10, dividing the mounting cavity into a first mounting cavity 14 and a second mounting cavity 16. The partition 12 divides the mounting cavity, functionally dividing the internal space of the housing 10. The first mounting cavity 14 has an opening for installing plug-in components, and is therefore used to install plug-in components. The second mounting cavity 16 is used to install power modules 32 and other modules. Plug-in components and power modules 32 are the two components that generate the most heat in the chassis. Therefore, using the partition 12 to separate the mounting cavities of these two components for separate heat dissipation can improve the heat dissipation performance of the plug-in components in the chassis and improve the stability of system operation. In addition, the first mounting cavity 14 also includes:

[0034] Figure 3 This is a structural schematic diagram of an embodiment of the second support of this utility model.

[0035] Please also refer to Figure 3 The support assembly is located at the bottom and / or top of the plug-in component, including at least two sets of first brackets 181 fixedly disposed in the chassis and at least one second bracket 182 with both ends respectively mounted on the first brackets 181. The second bracket 182 includes a guide portion 184 for mounting the plug-in component, and the plug-in component is adjusted to the mounting position in the first mounting cavity 14 by means of the second bracket 182.

[0036] The plug-in component is the physical carrier of PXIe (PCI extensions for Instrumentation) / PCIe (Peripheral Component Interconnection express) board modules. Its design deeply integrates the concept of modular instrument systems with high-speed serial bus technology. Based on the PCI Express bus expansion, it adopts a point-to-point serial interface, and the module size is standardized, with various slot width specifications such as 1-slot width and 2-slot width. In this embodiment, the plug-in component is a PXIe modular board, such as a PXIe modular arbitrary waveform generator (AWG) or a PXIe modular digital storage oscilloscope (DSO). As those skilled in the art will understand, the plug-in component includes, but is not limited to, the aforementioned PXIe modular board.

[0037] In some implementations, two or more sets of first supports 181 may be provided, and the number of first supports 181 may be reasonably selected according to the specifications of the plug-in component to improve the stability of the plug-in component placement.

[0038] In some implementations, support components are symmetrically arranged at the bottom and top of the plug-in to improve the stability of the plug-in under lateral forces when it is placed.

[0039] Figure 4 This is a schematic diagram of the electrical principle of an embodiment of the present invention;

[0040] Please also refer to Figure 4 A plug-in assembly is located on the plug-in side of the plug-in component. The plug-in assembly includes several plug slots 201 that mate with the pins on the plug-in component. A control plate 121 perpendicular to the plug-in component is flexibly electrically connected to the plug slots 201. When the plug-in component is adjusted to its installation position within the first mounting cavity 14 via the second bracket 182, the plug slots 201 flexibly electrically connected to the control plate 121 are not affected by their position and can be adjusted to match the position of the plug-in component within the range of the flexible connector.

[0041] Figure 5 This is a structural schematic diagram of an embodiment of the locking component of this utility model.

[0042] Please also refer to Figure 5 The locking assembly 22 is located on the opening side of the first mounting cavity 14, and includes an unlocked state that allows the plug-in component to be freely pushed in and out of the first mounting cavity 14, and a locked state that restricts the plug-in component from being freely pushed in and out of the first mounting cavity 14. This prevents the plug-in component from becoming loose at the interface or falling off the chassis during use.

[0043] The working process of the multi-slot embedded PXIe chassis for easy board installation provided in this application is as follows:

[0044] According to the specifications and size of the plug-in components, adjust the position of the second bracket 182 on the first bracket 181 and fix it. Adjust the locking component 22 to the unlocked state, push the plug-in component along the guide part 184, and insert the pins of the plug-in component facing the inside of the chassis into the insertion slot 201. In this way, insert multiple plug-in components into the chassis, adjust the locking component 22 to the locked state, and the plug-in components are assembled in the chassis.

[0045] The multi-slot embedded PXIe chassis provided in this application facilitates board installation. By setting a first bracket 181 at the bottom of the plug-in component and a second bracket 182 mounted on the first bracket 181, the user can adjust the installation position of the plug-in component, making reasonable use of the space inside the PXIe chassis. At the same time, the control board 121 is flexibly connected to the plug-in slot 201, avoiding direct force on the control board 121 during frequent plugging and unplugging of the component, which could cause the solder joints between the PCB and the plug-in slot 201 to loosen or fall off, thereby improving the service life and operational stability of the PXIe chassis.

[0046] In some implementation methods, please refer to Figure 2The second bracket 182 has countersunk holes 183 at its contacting ends with the first bracket 181. The first bracket 181 has several equally spaced first threaded holes 187. The first bracket 181 and the second bracket 182 are connected by fastening bolts. Depending on the specifications of the plug-in components, the countersunk holes 183 on the second bracket 182 are aligned with the first threaded holes 187 on the first bracket 181, thereby adjusting the relative installation position of the second bracket 182 and the first bracket 181. The fastening bolts are then tightened to fix the relative positions of the second bracket 182 and the first bracket 181. The PXIe chassis provided in this embodiment allows for adjustable relative positions of the second bracket 182 and the first bracket 181, accommodating plug-in components with different slot widths, providing flexibility and convenience. The countersunk holes 183 ensure the surface of the second bracket 182 remains flat, preventing the protrusion of the fastening bolts from affecting the insertion and removal of the plug-in components.

[0047] In some implementation methods, please refer to Figure 3 The guide section 184 is a guide groove 185 formed in the second bracket 182. The plug-in component is freely pushed into or pushed out of the first mounting cavity 14 through the guide groove 185. The guide groove 185 provides guidance during the insertion of the plug-in component into the insertion slot 201, so that the plug-in component enters smoothly in the correct direction and ensures the accuracy of the connection position between the pin of the plug-in component and the insertion slot 201.

[0048] like Figure 3 As shown, in some embodiments, the inner side of the guide groove 185 is provided with at least one set of elastic protrusions 186 for clamping and positioning the plug-in component. The elastic protrusions 186, through their elastic deformation capability, can tightly conform to the outer surface of the plug-in component, thereby achieving stable clamping and fixation of the plug-in component. This clamping method not only effectively prevents the plug-in component from shaking or falling out within the guide groove 185, but also ensures the stability and reliability of the plug-in component during the connection process. Because the elastic protrusions 186 have a certain degree of elasticity, they can absorb and disperse the impact force between the plug-in component and the guide groove 185 when the plug-in component is inserted into or removed from the guide groove 185, playing a buffering and shock-absorbing role. This helps protect the plug-in component and the guide groove 185 from damage and extends their service life.

[0049] In some embodiments, the partition 12 is a control board 121, allowing the control board 121 to function as the partition 12 without requiring additional components, thus reducing costs. A third bracket 200 is also included, on which the plug-in assembly is mounted. The third bracket 200 is connected to the second bracket 182, and the plug-in slot 201 is flexibly electrically connected to the control board 121 via an FFC (Flexible Flat Cable) 202. The position of the plug-in assembly is adjusted within the length of the FFC 202. The third bracket 200 acts as a reinforcing rib, bearing the force of the plug-in assembly during insertion and removal, preventing the force from being transmitted to the control board 121 and avoiding the problem of solder joints on the control board 121 detaching due to frequent insertion and removal, thereby extending the service life of the control board 121. Simultaneously, the plug-in slot 201, located on the third bracket 200, facilitates replacement. Replacement only requires resoldering the contacts between the FFC 202 and the plug-in slot 201, without disassembling or resoldering the control board 121.

[0050] like Figure 5 As shown, in some embodiments, the plug-in component further includes a plug-in panel 26, a locking assembly 22 consisting of a fastening screw 221 disposed on the plug-in panel 26, and a first threaded hole 187 disposed on the opening side of the first mounting cavity 14, wherein the fastening screw 221 is screwed into the first threaded hole 187 in the locked state.

[0051] In some embodiments, the plug-in panel 26 is further provided with a sleeve 223, through which the fastening screw 221 is connected to the second threaded hole 222. The sleeve 223 is made of stainless steel or other alloy material. The sleeve 223 prevents the fastening screw 221 from causing wear on the plug-in panel 26 during frequent tightening, which could lead to unstable locking of the plug-in component and reduce its service life.

[0052] Figure 6 This is a structural schematic diagram of an embodiment of the locking component of this utility model.

[0053] Figure 7 This is an enlarged structural schematic diagram of A in one embodiment of the locking component of this utility model.

[0054] like Figure 6 As shown, in some embodiments, the locking assembly 22 includes a locking lever 224 rotatably disposed on the opening side of the first mounting cavity 14. The locking lever 224 includes a locking state that abuts against the insert / removable member to restrict the insert / removable member from freely pushing in and out of the first mounting cavity 14, and an unlocking state that spacees the insert / removable member to allow the insert / removable member to freely push in and out of the first mounting cavity 14. Figure 7As shown, specifically, it also includes cranks 226 connected to both ends of the locking rod. One end of the cranks 226 is rotatably mounted on the side wall of the housing, and the other end is connected to the locking rod. The length of the cranks 226 constitutes the sweeping range of the locking rod 224 when it rotates. Within the sweeping range, rotating the locking rod 224 can block and limit the insertion / removal component, keeping it in a locked state, or allow it to pass through the insertion / removal component, switching it to an unlocked state. A torsion spring 225 is sleeved on the cranks 226 to maintain the locked state. The two ends of the torsion spring 225 abut against the fixed part and the movable part, respectively, forming a spring force. In this embodiment, the fixed part is the side wall of the housing 10, and the movable part is the locking rod 224. In the initial state, the locking rod 224, under the spring force of the torsion spring 225, rotates towards the inside of the opening of the first mounting cavity 14, abutting against the insertion / removal component. When installing the plug-in component, the user moves the locking lever 224, which rotates outward toward the opening of the first mounting cavity 14. The torsion spring 225 stores force, and the opening of the first mounting cavity 14 opens. The user pushes the plug-in component in through the guide part 184 to install it into the first mounting cavity 14. The user releases the locking lever 224, and the torsion spring 225 drives the locking lever 224 to rotate back through the restoring force, abutting against the plug-in component to restrict its ejection.

[0055] In practical applications, if the PXIe board (plug-in component) cannot be stably connected to the PXIe chassis, it will affect the signal transmission quality and even lead to inaccurate test results. Therefore, ensuring the stable installation and connection of the PXIe board (plug-in component) within the PXIe chassis is crucial. The multi-slot embedded PXIe chassis provided in this embodiment facilitates board installation. A rotating locking lever 224 is provided on the opening side of the first mounting cavity 14, making it very easy to limit and lock the PXIe board. Simply push it outwards to install the PXIe board; releasing the locking lever 224 allows the torsion spring 225 to hold the PXIe board (plug-in component) in place. In production, when batch testing of devices under test (e.g., chips) is required, this helps improve testing efficiency, thereby increasing production efficiency.

[0056] In some implementations, after the user pushes in the plug-in component, the locking lever 224 abuts against and limits the plug-in component, and the user tightens the fastening screw 221.

[0057] In some implementation methods, please refer to Figure 2 and Figure 4 At least one set of cooling fans 28 is installed in the first mounting cavity 14, and a through hole is provided for air exchange between the cooling fans 28; a sensor bracket 30 is also provided in the first mounting cavity 14, and a sensor 31 is mounted on the sensor bracket 30, which is electrically connected to the control board 121. Figure 7 As shown, the cooling fan 28 automatically adjusts its speed based on the data from the sensor 31 to ensure that the plug-in component achieves the best heat dissipation level.

[0058] PXIe chassis can accommodate different PXIe boards, allowing for the combination and integration of various PXIe boards, or the cascading of the same type of PXIe boards to obtain more channels to meet testing needs. Traditional benchtop instruments require a significant amount of space after cascading or combining, and the cascading cables are complex. While PXIe boards and chassis offer the advantage of miniaturization, ensuring adequate cooling of the boards generating substantial heat within a limited space presents significant challenges and adjustments. This embodiment provides a multi-slot embedded PXIe chassis for easy board installation, with a cooling fan 28 positioned below the boards, creating airflow channels between the PXIe boards. This design balances miniaturization with effective heat dissipation.

[0059] In some embodiments, a power module 32 is provided in the second mounting cavity 16. The power module 32 is electrically connected to the control board 121, and feet 34 are provided on the bottom of the enclosure 10. The power module 32 is separately provided in the second mounting cavity 16 to improve the overall heat dissipation of the PXIe enclosure and enhance system performance.

[0060] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
