Description

Technical Field

[0001] This utility model relates to the field of operation and transportation technology, and specifically to a puller for VPX architecture modules. Background Technology

[0002] Currently, aerospace telemetry and control products are gradually developing towards integration, large-scale, and modularization. In order to meet these requirements, the number of times each module of the aerospace VPX telemetry and control product is plugged in and replaced is also increasing as the number of modules increases. Consequently, the issue of module plugging and unplugging has gradually become a focus.

[0003] Since most existing pullers are integrated disassembly and assembly modules, although they can meet the module insertion and removal requirements, their structure is complex and they occupy a large area of ​​the module socket installation plane. The size of the socket panel space is very important for aerospace products. A larger panel space allows for more options for connectors and cables.

[0004] Therefore, a puller is needed for aerospace VPX architecture modules to obtain a larger socket mounting surface space and a more convenient and safer way to pull out the modules. Summary of the Invention

[0005] This invention aims to solve the problems of the VPX module's built-in puller occupying a large area of ​​the socket mounting plane, having a complex structure, and being easily damaged. It provides a puller for VPX architecture modules, using a single-part structure to design the VPX puller as a simple and durable device. While ensuring convenient pulling of the VPX module, it also provides more space on the socket panel, allowing the module to accommodate more connectors and thus achieve more functions.

[0006] This utility model provides a puller for VPX architecture modules, including a handle, a movable pivot arc surface, a diagonal rod, a cantilever arm with a support lug connected in sequence, and a puller lug connected to the end of the cantilever arm and extending to both sides. The handle has a flat structure, the diagonal bar extends upward, the angle between the handle and the diagonal bar is greater than 90°, the connection surface between the diagonal bar and the cantilever arm is located in the middle of the front end of the diagonal bar, the cantilever arm extends downward, the width of the cantilever arm is less than the maximum width of the diagonal bar, the angle between the cantilever arm and the diagonal bar is less than 90°, and the pull-out cantilever is a cylindrical structure. The side connection of the VPX architecture module to be pulled out has an auxiliary pulling hole, and the outer diameter of the pulling support is smaller than the inner diameter of the auxiliary pulling hole.

[0007] The puller for VPX architecture modules described in this embodiment, as a preferred embodiment, further includes a protective sleeve connected to the outside of the arc surface of the moving fulcrum, the outside of the front side of the handle, and the outside of the rear side of the diagonal bar.

[0008] In this embodiment, a puller for a VPX architecture module is described. In a preferred embodiment, a protective sleeve is heat-shrinkably connected to the outside of the moving fulcrum arc surface, the front side of the handle, and the rear side of the diagonal bar using a hot air gun.

[0009] In this embodiment, a puller for a VPX architecture module is described. In a preferred embodiment, when the puller is placed horizontally, both the cantilever arm and the puller lug are higher than the placement surface.

[0010] In this embodiment, a puller for a VPX architecture module is preferably constructed with the handle, the movable pivot arc surface, the diagonal rod, the cantilever arm of the puller lug, and the puller lug as an integrated structure.

[0011] In this embodiment, a puller for a VPX architecture module is described, in a preferred embodiment, the width of the diagonal bar is greater than the total width of the puller lugs; the highest point of the lug cantilever is higher than the highest points at both ends of the diagonal bar.

[0012] In this embodiment, a puller for a VPX architecture module is provided, as a preferred embodiment, with a chamfered edge at the connection between the diagonal rod and the cantilever arm.

[0013] In this embodiment, a puller for a VPX architecture module is described, and preferably, the top of the slant bar has an arc-shaped structure.

[0014] The puller for VPX architecture modules described in this embodiment, as a preferred embodiment, includes a puller chassis support surface for the VPX architecture module to be pulled.

[0015] In this embodiment, a puller for a VPX architecture module is described, in a preferred embodiment, the angle between the handle and the diagonal bar is 100±1°, and the angle between the cantilever arm and the diagonal bar is 50±1°.

[0016] This invention relates to the field of aerospace technology, specifically to the design of integrated telemetry and control equipment for aerospace launch vehicles. The invention comprises a puller body and a protective sleeve. The puller body consists of a puller lug, a lug cantilever, and a movable fulcrum arc surface. The protective sleeve is heated and tightly connected to the puller body by a hot air gun. This invention provides a puller for replacing 3U and 6U modules in aerospace VPX architecture. It offers more socket panel space for standard VPX modules and effectively prevents short circuits in the VPX module circuit caused by metal debris generated during the pull-out process. Furthermore, the puller is robust, durable, and has anti-slip and wear-resistant properties.

[0017] This utility model has the following advantages: Compared to existing technologies, the VPX plug module puller currently used in aerospace telemetry and control products has a complex structure and occupies a large area of ​​the socket panel. Complex structure means a high rate of damage, and a large socket panel area means a small usable socket area. Normally, structural damage and a small usable socket area can be addressed by replacing damaged modules or increasing the product size. However, for aerospace telemetry and control products, either replacing damaged parts or increasing the size would multiply the overall project cost. In this invention, a single-part integrated molding design reduces the probability of puller damage; a protective sleeve design prevents metal debris from generating during the pull-out process and causing short circuits in electronic products; and the design of pull-out assist ears and holes expands the usable socket panel area to the maximum size of the VPX standard module.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example 1

[0021] A puller for VPX architecture modules includes a handle 1, a movable pivot arc surface 2, a diagonal bar 3, a cantilever arm 4, a puller ear 5 connected to the end of the cantilever arm 4 and extending to both sides, and a protective sleeve 8 connected to the outside of the movable pivot arc surface 2, the outside of the front side of the handle 1, and the outside of the rear side of the diagonal bar 3. The handle 1 has a flat structure, the diagonal rod 3 extends upward, the angle between the handle 1 and the diagonal rod 3 is greater than 90°, the connection surface between the diagonal rod 3 and the cantilever arm 4 is located at the middle of the front end of the diagonal rod 3, the cantilever arm 4 extends downward, the width of the cantilever arm 4 is less than the maximum width of the diagonal rod 3, the angle between the cantilever arm 4 and the diagonal rod 3 is less than 90°, and the pull-out cantilever 5 has a cylindrical structure. The VPX architecture module 6 to be pulled out has a side connection to the pull-out aid hole 7, and the outer diameter of the pull-out support 5 is smaller than the inner diameter of the pull-out aid hole 7.

[0022] The protective sleeve 8 is heat-shrinkly connected to the outside of the moving fulcrum arc surface 2, the front side of the handle 1, and the rear side of the diagonal rod 3 by a hot air gun.

[0023] When the puller is placed horizontally, both the cantilever arm 4 and the puller lug 5 are higher than the placement surface.

[0024] The handle 1, the movable fulcrum arc surface 2, the diagonal bar 3, the cantilever arm 4, and the pull-out arm 5 are an integrated structure.

[0025] The width of the diagonal bar 3 is greater than the total width of the pull-out support 5; the highest point of the support cantilever 4 is higher than the highest points at both ends of the diagonal bar 3.

[0026] A chamfer is provided at the connection between the diagonal rod 3 and the cantilever arm 4.

[0027] The top of the diagonal bar 3 has an arc-shaped structure.

[0028] The VPX architecture module 6 to be pulled out includes the puller chassis support surface 9.

[0029] The angle between handle 1 and diagonal bar 3 is 100±1°, and the angle between cantilever arm 4 and diagonal bar 3 is 50±1°.

[0030] In this embodiment, the main body structure of the puller consists of a handle 1, a movable fulcrum arc surface 2, a diagonal rod 3, a cantilever arm with a support lug 4, and a puller lug 5. The protective sleeve 8 is heated by a hot air gun and tightly connected to the puller body.

[0031] The puller body adopts a single-part one-piece molding design to ensure the durability and reliability of the puller structure; The puller adopts a double-sided symmetrical puller lug design to ensure the puller's interchangeability and versatility on both sides, allowing the same puller to be used on both the left and right sides for pulling. The arc surface 2 of the lifting and moving fulcrum is wider than the cantilever arm 4 on both sides, which reduces the support pressure on the chassis side wall at the lifting and moving fulcrum, reduces the loss caused by friction, reduces the pressure at the arc surface 2 of the moving fulcrum during the lifting and moving process, and reduces the possibility of damage to the chassis side wall. When the puller is placed horizontally, both the puller lug 5 and the lug cantilever 4 are higher than the placement surface. This ensures that the puller's pulling stroke can completely pull the VPX plug away from the socket. At the same time, the puller is easy to store in non-working environments, meaning that the puller can be stacked flat together for easy storage.

[0032] The puller body and the protective sleeve 8 are connected by heat shrinking with a hot air gun. The protective sleeve 8 wraps around the arc surface 2 of the moving fulcrum. The pull-out hole 7 of the puller module is used to increase the usable area of ​​the socket mounting surface.

[0033] like Figures 1-6 As shown in the figure, this utility model provides a puller for aerospace VPX architecture modules.

[0034] like Figure 4 As shown in the figure, as a preferred embodiment of the present invention, the illustrated embodiment includes a puller body, a protective sleeve 8, a puller chassis support surface 9, and a VPX architecture module 6 to be pulled. When performing the pull-out operation, the pull-out support ear 5 is inserted into the pull-out hole 7, and the left and right ends of the puller move downwards, using the contact plane between the protective sleeve 8 and the chassis support surface as the fulcrum, thereby driving the VPX standard module plug and socket to separate and complete the pull-out.

[0035] like Figure 4 As shown, the puller completes the pulling by making full use of the side wall support of the chassis. Through the design of the arc surface 2 of the moving fulcrum of the puller, the fulcrum moves slowly away from the pulling lug 5 during the pulling process, effectively dispersing the stress on the side wall of the fulcrum during the pulling process, thereby extending the service life of the protective sleeve.

[0036] like Figure 5 As shown, the pull-out hole 7 of the VPX architecture module 6 to be pulled out using this utility model has a smaller diameter and can be placed on the module guide rail position on the edge of the VPX socket, thereby giving the VPX architecture module 6 to be pulled out a larger socket panel space, allowing for the installation of more external plug-ins and the realization of more functions.

[0037] like Figure 6 As shown, the puller is designed with portability in mind. The puller module can use a maximum of two pullers. In this puller storage design, two identical pullers can be conveniently stored each time it is carried. According to the arrangement shown in the figure, it can be easily inserted into the package or tied for carrying.

[0038] In this embodiment, the diameter of the pull-out support lug 5 is 4mm, the diameter of the pull-out assist hole 7 is 5mm, the protruding length of the pull-out support lug 5 is 5±0.5mm, the angle between the support lug cantilever 4 and the inclined rod 3 is 50°±1°, the angle between the inclined rod 3 and the main body rod (handle 1) is 100°±1°, and the diameter of the puller protective sleeve 8 before heat shrinking is 20mm, which fits tightly with the puller body after heat shrinking. The cross-sectional perimeter of the inclined rod 3 is 44.65mm, and when laid flat, the front end of the pull-out support lug 5 is higher than the plane of the handle 1. The total width of the pull-out lug 5 is 17mm, and the total width of the diagonal bar 3 is 19mm; In this embodiment, the material of the puller body is aluminum alloy 2A12, a lightweight material with high strength, and the material of the protective sleeve 8 is PE plastic.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
