Description

Technical Field

[0001] The utility model belongs to the technical field of communication equipment, and in particular relates to a VPX chassis which is convenient for plugging and unplugging board modules. Background Art

[0002] During use of the existing conduction-cooled VPX chassis, since the edges of the chassis slots are all right angles, when the VPX board modules are disassembled and assembled, the floating of the locking strips during the plug-in and unplugging process of the VPX board modules may cause bumps on the structural parts, causing the boards to become stuck during the plug-in and unplugging process. In addition, frequent bumps may damage the protective layer on the surface of the structural parts, affecting the three-proof performance of the structural parts. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a VPX chassis that is convenient for plugging and unplugging board modules, which can avoid structural collisions during the plugging and unplugging process of the VPX board and card, resulting in plugging and unplugging jams, so that the VPX board and card can be smoothly inserted into the chassis, while avoiding the problem of reducing the three-proof performance of the structure due to collisions.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A VPX chassis that facilitates the plugging and unplugging of board modules, comprising a box body, a plug-in interface for the board template to be plugged in is provided on the top of the box body, a plurality of equally spaced guide rails are provided on the inner wall of the box body, the length direction of the guide rails is consistent with the plug-in direction of the board template, a slot adapted to the board module is formed between two adjacent guide rails, the side surfaces on both sides of the end of the guide rails are guide slopes inclined toward the axial center line of the guide rails, and the distance between the planes where the two ends of the guide slopes are located and along the plug-in direction of the board module is greater than the floating amount of the locking strip on the board module.

[0006] Furthermore, the included angle between the guiding inclined surface and the plugging direction of the board module is 5°.

[0007] Furthermore, a plurality of lever bosses cooperating with the pull-out aids on the board template are provided on the inner wall of the box at the insertion interface, and the plurality of lever bosses correspond one-to-one to the plurality of slots.

[0008] Furthermore, chamfers are provided on both sides of the bottom where the lever boss is connected to the box body.

[0009] Furthermore, two opposite inner walls of the box body are provided with a plurality of guide rails, and the guide rails on both sides of the box body correspond to each other one by one.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. The utility model sets a guide slope and makes the floating value greater than the locking strip on the board module, so that when the VPX board module is inserted into the box, it can avoid collision with the slot, thereby making the insertion and removal of the VPA board module smoother and less stuck.

[0012] 2. The utility model provides a lever boss and provides chamfers on both sides of the connection between the bottom of the lever boss and the box body, so that when the VPX board module is pulled out of the box body, the locking strip on the board module will not collide with the lever boss when it is completely loosened, thereby preventing the protective layer on the surface of the box body from being damaged due to collision, avoiding the problem of reducing the three-proof performance of the structure due to collision.

[0018] The present invention is further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0019] like Figure 1-Figure 3 As shown, a VPX chassis for convenient plugging and unplugging of board modules includes a box body 1, a plug-in interface for plugging in board templates is provided on the top of the box body 1, a plurality of equally spaced guide rails 2 are provided on the inner walls on both sides of the box body 1, and the guide rails 2 on both sides of the box body 1 correspond to each other, the length direction of the guide rail 2 is consistent with the plug-in direction of the board template, and a slot 3 adapted to the board module is formed between two adjacent guide rails 2. When plugging in the VPX board module, the VPX board module is inserted into the box body 1 through the plug-in interface, so that the two ends of the VPX board module are respectively inserted into the two corresponding slots 3.

[0020] like Figure 3 , Figure 4As shown, the two side surfaces of the end of the guide rail 2 are guide slopes 4 inclined toward the axis of the guide rail 2, and the distance x between the planes where the two ends of the guide slope 4 are located and along the plug-in direction of the board module is greater than the floating amount of the locking strip on the board module. In this way, when the VPX board module is inserted into the box 1, the VPX board module will not collide with the slot 3 through the setting of the guide slope 4, so that the VPX board module can be smoothly inserted into the box 1 to prevent jamming. In this embodiment, the angle between the guide slope 4 and the plug-in direction of the board module is 5°, so that x is greater than the floating amount of the locking strip on the board module.

[0021] like Figure 2 , Figure 3 As shown, the inner wall of the box body 1 is provided with a plurality of lever bosses 5 cooperating with the pull-out aids on the board template at the insertion interface. The plurality of lever bosses 5 correspond to the plurality of slots 3 one by one, so that when the board module is pulled out, the pull-out aid can abut against the end face of the adjacent guide rail 2 while leveraging the lever bosses 5, thereby giving the board module a reaction force to facilitate the pull-out of the board module. In addition, chamfers are provided on both sides of the bottom where the lever bosses 5 are connected to the box body 1. The lever bosses 5 are small in size. Combined with the chamfer setting, when the VPX board module is pulled out of the box body 1, the locking strip on the board module will not collide with the lever bosses 5 when it is completely loosened, thereby preventing the protective layer on the surface of the box body 1 from being damaged due to collisions, and avoiding the problem of reducing the three-proof performance of the structure due to collisions.

[0022] Finally, although the above description has shown and described the embodiments of the present invention, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
