Description

Technical Field

[0001] The present application relates to the field of VPX board technology, and in particular to a board plug-in tool and a board assembly. Background Art

[0002] The VPX standard is mainly used in defense and military industry, aerospace, industrial measurement and control, radar communications and other fields to meet the needs of high-density, high-performance computing, as well as the needs of use in extremely harsh environments. The VPX standard includes air-cooled structure and conduction-cooled structure. During production testing or scientific research debugging, VPX boards need to be inserted into the chassis, and the insertion and removal of the boards require the use of an assisted puller. Since the chassis structure is divided into air-cooled and conduction-cooled structures, it is often necessary to install an air-cooled or conduction-cooled puller on the VPX board to meet the structural form of the chassis. The versatility is low, which greatly increases the workload. Repeated disassembly and assembly of structural parts increases the risk to a certain extent. Utility Model Content

[0030] Example 1

[0031] Reference Figures 1-8 This embodiment provides a board plug-in and pull-out tool, including at least two sets of connection components 100 and a target puller 200. The connection components 100 are used to install VPX boards 300, and the target puller 200 is detachably connected to one end of the corresponding connection component 100; wherein the target puller 200 is a puller adapted for a conduction-cooled chassis or a puller adapted for an air-cooled chassis.

[0032] Since the existing VPX board is directly assembled with the extractor, it is necessary to adapt the VPX board with the corresponding structure extractor according to the structure of the air-cooled chassis or the conduction-cooled chassis, which has low versatility. Alternatively, the corresponding structure extractor is repeatedly disassembled and assembled on the VPX board, which can easily damage the VPX board.

[0033] In this embodiment, the VPX board 300 can be installed independently through the additional connecting component 100, and then the target puller 200 can be assembled on one end of the connecting component 100, which changes the traditional structure in which the puller and the VPX board 300 are installed as one piece. Therefore, according to the usage requirements, a puller that can be adapted to a conduction-cooled chassis or a puller that can be adapted to an air-cooled chassis can be directly assembled on one end of the connecting component 100, thereby improving versatility and good compatibility.

[0034] As an optional embodiment, the connection assembly 100 includes guide rails 110 and docking blocks 120 . The VPX board 300 is installed between the guide rails 110 . The docking blocks 120 are detachably connected to the ends of the guide rails 110 . The docking blocks 120 are used to detachably connect to the target puller 200 .

[0035] In this embodiment, the guide rail 110 is strip-shaped, which is convenient for assembly on the side of the VPX board 300 and also provides a certain degree of protection. The target puller 200 is assembled via the docking block 120 on the guide rail 110, which can prevent the target puller 200 from being repeatedly disassembled and assembled with the guide rail 110 and causing damage to the guide rail 110. If the docking block 120 is damaged, only the docking block 120 can be replaced, thereby improving the utilization rate of the guide rail 110.

[0036] It should be noted that the docking block 120 and the guide rail 110 can be connected by screws to achieve a detachable connection, and the docking block 120 and the target extractor 200 can be connected by pins to achieve hinged assembly and facilitate disassembly.

[0037] As an optional embodiment, the connection assembly 100 further includes a plurality of fastening blocks 130 detachably connected to the guide rails 110. The fastening blocks 130 are used to secure the VPX board 300 between the guide rails 110. The fastening blocks 130 on the guide rails 110 can be used to secure the VPX board 300 individually, making assembly quick and easy, as well as disassembly convenient.

[0038] As an optional embodiment, the fastening block 130 includes a slider 131, a pressure block 132 and a first fastener (not shown in the figure). The slider 131 is slidably connected to the guide rail 110, and the pressure block 132 is connected to one side of the slider 131. A first positioning hole 1321 corresponding to the mounting hole of the VPX board 300 is provided on the pressure block 132, and the first fastener is connected between the first positioning hole 1321 and the mounting hole.

[0039] In this embodiment, the fastening block 130 can slide to a suitable position on the guide rail 110 through the slider 131. The suitable position is when the pressing block 132 corresponds to the mounting hole position of the VPX board 300. Then, the first fastener penetrates and connects the first positioning hole 1321 and the mounting hole of the VPX board 300, thereby fixing the VPX board 300. Therefore, it can take into account the different mounting hole positions of multiple VPX boards 300 at the same time, and can adapt to the installation of VPX boards 300 of various specifications, further improving versatility.

[0040] It should be noted that the first fasteners may be fasteners such as screws and pins.

[0041] As an optional embodiment, the guide rail 110 is provided with a guide groove 111 along the length direction of the guide rail 110 to cooperate with the slider 131. The guide groove 111 can be set on the outer wall of the guide rail 110, and the slider 131 is located on the top surface of the guide rail 110 as a whole. A part of the slider 131 can be extended to be slidably connected to the guide groove 111, and the sliding guiding property is good and not easy to fall off.

[0042] As an optional embodiment, a second positioning hole 1311 is provided on the slider 131, and a limiting groove 112 that cooperates with the second positioning hole 1311 is provided on the guide rail 110 along the length direction of the guide rail 110, and a second fastener 140 is provided between the second positioning hole 1311 and the limiting groove 112.

[0043] In this embodiment, when the slider 131 slides to different positions on the guide rail 110, the second fastener 140 can penetrate the second positioning hole 1311 on the slider 131 and the limiting groove 112 on the guide rail 110, thereby fixing the slider 131 at the corresponding position of the guide rail 110, further improving the fixing reliability of the slider 131.

[0044] As an optional embodiment, two fastening blocks 130 are provided on each guide rail 110 , that is, each side of the VPX board 300 is secured by two fastening blocks 130 , thereby ensuring secure fixation and avoiding excessive installation work.
