Description

Technical Field

[0001] The present application relates to the technical field of extraction aid devices, and in particular to a VPX module structure. Background Art

[0002] The ejector is installed on the communication module and is used as an auxiliary structure when the module is inserted into and removed from the chassis.

[0003] In the prior art, it is usually necessary to machine a mounting groove for installing the puller at the edge of the VPX module, and a tongue structure for cooperating with the puller needs to be machined on the inner wall of the mounting groove. The tongue structure limits the puller and keeps the puller on the VPX module when the puller is not needed. However, the mounting groove has a complex structure, and there is a very small inner fillet at the tongue structure, resulting in low processing efficiency. In addition, the wall thickness of the part where the tongue structure cooperates with the puller is weak, and it is constantly worn during the process of cooperating with the puller, making it easy to break and fail. Once it fails, the structural component is difficult to repair, and the shell can only be replaced as a whole, which causes waste. Summary of the invention

[0004] The main purpose of the present application is to provide a VPX module structure, aiming to solve the technical problems in the prior art that the processing of the installation groove is complicated and the tongue structure on the inner wall of the installation groove is prone to cracking and failure and is difficult to repair.

[0005] To achieve the above-mentioned purpose, the present application provides a VPX module structure, including a module body, which is provided with a mounting groove; an ejector, one end of which is hinged in the mounting groove and the other end is a free end, and the free end of the ejector can rotate around the hinged end so that the free end of the ejector can be selectively moved out of the mounting groove; a latch tongue, which is detachably arranged in the mounting groove; wherein a protrusion is provided on a side of the latch tongue close to the free end of the ejector, and the protrusion forms a limiting groove with the side wall of the mounting groove, and a limiting block is provided at the free end of the ejector, and the limiting block can selectively enter the limiting groove to limit the movement of the ejector.

[0006] Optionally, the tongue is arranged in the installation groove by screws. The tongue is detachably installed in the installation groove by screws, which is convenient and quick to remove and install, and does not need to process the inner wall of the installation groove to form a structure for the stopper block to cooperate, thereby reducing the difficulty of processing the installation groove.

[0007] Optionally, the mounting groove includes a first side wall and a second side wall connected to each other; the latch tongue includes a third side wall abutting against the first side wall and a fourth side wall abutting against the second side wall, the first side wall and the second side wall are used to limit the relative rotation of the latch tongue, and the first side wall and the protrusion form the limiting groove. The latch tongue is limited in two directions by the existing first side wall and the second side wall of the mounting groove, and the mounting structure of the latch tongue is used to fix the latch tongue, thereby preventing the latch tongue from rotating at will and improving the stability of the latch tongue.

[0008] Optionally, a receiving groove is provided at the free end of the pull-out aid, and part of the limit block is received in the receiving groove. The limit block can move along the receiving groove so that the limit block is separated from the protrusion to release the limiting effect of the limit block relative to the protrusion. The receiving groove can be provided to accommodate the limit block. When the limiting effect on the pull-out aid needs to be released, it is only necessary to control the limit block to move toward the receiving groove without removing the latch tongue, so that the unlocking can be realized quickly.

[0009] Optionally, the side wall of the pull-out aid is provided with a slide groove connected to the receiving groove, and the outer wall of the limit block is connected with a connecting block penetrating the slide groove, and the connecting block can move along the extending direction of the slide groove. By providing the connecting block and the slide groove, it is convenient to apply an external force to the limit block through the connecting block to control the limit block to move toward the receiving groove.

By dividing the receiving groove into the first section and the second section, the first section can play a role of limiting and guiding the limit member to prevent the limit member from shaking arbitrarily, and the return spring applies a thrust to the limit block so that the limit block can be automatically reset.

[0011] Optionally, a first inclined surface is provided on a side of the protrusion away from the limiting groove, and the limiting block has a second inclined surface for cooperating with the first inclined surface. By providing the first inclined surface and the second inclined surface that cooperate with each other, when the pull-out aid is limited and locked, a horizontal component force can be applied to the limiting block through the contact between the first inclined surface and the second inclined surface to realize that the limiting block automatically enters the receiving groove, so that the limiting block can pass over the protrusion and enter the limiting groove.

[0029] Example 1

[0030] Reference Figure 1-Figure 5 This embodiment provides a VPX module structure, including:

[0031] The module body 10 is a VPX module, which is a modular product based on the VPX architecture. VPX (also known as VITA 46) is an ANSI standard (ANSI / VITA 46.0-2019) that provides support for switching structures through new high-speed connectors for VMEbus-based systems.

[0032] The pull-out aid 20 is an auxiliary force structure used when the module body 10 is inserted into and pulled out of the chassis.

[0033] The latch tongue 30 is used to cooperate with the ejector aid 20 to limit the position of the ejector aid 20. When the ejector aid 20 is not needed to assist the module body 10, the latch tongue 30 limits the free end 21 of the ejector aid 20 from rotating around the hinge end 22 to fix the ejector aid 20 on the module body 10.

[0034] In this embodiment, a VPX module structure includes a module body 10, an ejector 20 and a latch 30. A mounting groove 50 is provided on the module body 10; one end of the ejector 20 is hinged in the mounting groove 50, and the other end of the ejector 20 is a free end 21, and the free end 21 of the ejector 20 can rotate around the hinge end 22 so that the free end 21 of the ejector 20 can be selectively moved out of the mounting groove 50; the latch 30 is detachably arranged in the mounting groove 50; wherein, a protrusion 31 is provided on one side of the latch 30 close to the free end 21 of the ejector 20, and the protrusion 31 forms a limiting groove 32 with the side wall of the mounting groove 50, and a limiting block 40 is provided at the free end 21 of the ejector 20, and the limiting block 40 can selectively enter the limiting groove 32 to limit the movement of the ejector 20.

[0035] By arranging a detachable latch 30 in the mounting groove 50, the latch 30 has a protrusion 31, and the limit block 40 on the pull-out aid 20 can form a limit structure with the protrusion 31 on the latch 30. There is no need to process a structure that cooperates with the limit block 40 on the mounting groove 50, thereby reducing the difficulty of processing the mounting groove 50. The latch 30 is detachable and can be replaced when the protrusion 31 is worn and consumed, without replacing the module body 10, thereby reducing maintenance costs.

[0036] Specifically, the mounting groove 50 is arranged at the edge of the module body 10, and the groove structure of the mounting groove 50 is a long strip, and the outer side of the mounting groove 50 passes through the edge of the module body 10. One end of the puller 20 is hinged in the mounting groove 50 by a screw, and the position where the puller 20 and the mounting groove 50 are hinged is the hinge end 22. The entire puller 20 can be accommodated in the mounting groove 50. When the puller 20 is needed, the free end 21 of the puller 20 rotates counterclockwise around the hinge end 22, and the free end 21 of the puller 20 moves to the mounting groove 50, so as to facilitate the insertion and extraction of the module body 10 by applying force to the puller 20. The limit groove 32 is formed by the protrusion 31 on the latch 30 and the inner wall of the mounting groove 50. When the limit block 40 on the puller 20 is located in the limit groove 32, the limit block 40 is locked. When the limit block 40 is removed from the limit groove 32, the locking state can be released. One unlocking method may be that the latch tongue 30 is detachably arranged in the mounting groove 50. By removing the latch tongue 30 or moving the latch tongue 30 upward by a certain distance, the protrusion 31 is misaligned with the limit block 40, thereby releasing the limit on the puller 20. The latch tongue 30 can be made of high-strength materials such as stainless steel to improve its durability. When the latch tongue 30 mating part is damaged, the latch tongue 30 can be replaced separately without replacing the entire VPX module structure, thereby improving the flexibility of maintenance; the latch tongue 30 can be made into a standard part by die-casting, which can greatly save processing costs and improve economy in mass production.

[0037] Example 2

[0038] As an optional implementation, refer to Figure 1 and Figure 4 A VPX module structure of this embodiment provides a specific structure for connecting the tongue 30 with the installation slot 50.

[0039] In this embodiment, the tongue 30 is set in the installation groove 50 by means of screws 33. The tongue 30 is detachably installed in the installation groove 50 by means of screws 33, and the removal and installation are convenient and quick, and there is no need to process the inner wall of the installation groove 50 by means of processing to form a structure for the stop block 40 to cooperate, thereby reducing the processing difficulty of the installation groove 50.

[0040] Specifically, the latch tongue 30 is provided with a countersunk hole through it along its thickness direction, and a threaded hole that can be aligned with the countersunk hole is provided on the bottom wall of the mounting groove 50. After the countersunk hole and the threaded hole are aligned, the screw 33 is threadedly matched with the threaded hole.

[0041] Example 3

[0042] As an optional implementation, refer to Figure 1-Figure 4 A VPX module structure of this embodiment provides a specific structure of a mounting slot 50.

[0043] In this embodiment, the mounting groove 50 includes a first side wall 51 and a second side wall 52 connected to each other; the latch tongue 30 has a third side wall 34 abutting against the first side wall 51 and a fourth side wall 35 abutting against the second side wall 52. The first side wall 51 and the second side wall 52 limit the relative rotation of the latch tongue 30, and the first side wall 51 and the protrusion 31 form a limiting groove 32. The latch tongue 30 is limited in two directions by the existing first side wall 51 and the second side wall 52 of the mounting groove 50, and the mounting structure of the latch tongue 30 is used to fix the latch tongue 30, so as to prevent the latch tongue 30 from rotating at will and improve the stability of the latch tongue 30.

[0044] Specifically, the plane where the first side wall 51 is located is perpendicular to the plane where the second side wall 52 is located, and the corners of the first side wall 51 and the second side wall 52 are rounded. The first side wall 51 and the second side wall 52 reduce the degree of freedom of the tongue 30, and the tongue 30 is further fixed by the screw 33 to prevent the tongue 30 from rotating at will.

[0045] Example 4

[0046] As an optional implementation, refer to Figure 3 A VPX module structure of this embodiment provides a specific structure for connecting a limit block 40 with a pull-out aid 20 .

[0047] In this embodiment, the free end 21 of the ejector 20 is provided with a receiving groove 60, and part of the limit block 40 is received in the receiving groove 60. The limit block 40 can move along the receiving groove 60 to disengage the limit block 40 from the protrusion 31, so as to release the limiting effect of the limit block 40 relative to the protrusion 31. The receiving groove 60 can be provided to accommodate the limit block 40. When the limiting effect on the ejector 20 needs to be released, it is only necessary to control the limit block 40 to move toward the receiving groove 60, and there is no need to remove the latch 30, so that the unlocking can be realized quickly.

[0048] Specifically, the accommodating groove 60 extends in the transverse direction, and the left side of the accommodating groove 60 passes through the outer wall of the pull-out aid 20 to allow the limiting block 40 to move left and right, and the inner wall of the accommodating groove 60 and the outer wall of the limiting block 40 are adapted to each other.

[0049] Example 5

[0050] As an optional implementation, refer to Figure 3 A VPX module structure of this embodiment provides a specific structure capable of controlling the movement of the limit block 40.

[0051] In this embodiment, the side wall of the pull-out aid 20 is provided with a slide groove 42 connected to the receiving groove 60, and the outer wall of the limit block 40 is connected with a connecting block 41 penetrating the slide groove 42, and the connecting block 41 can move along the extension direction of the slide groove 42. By providing the connecting block 41 and the slide groove 42, it is convenient to apply an external force to the limit block 40 through the connecting block 41 to control the limit block 40 to move toward the receiving groove 60.

[0052] Specifically, one end of the connection block 41 is connected to the limit block 40 , and the other end of the connection block 41 can be connected to a handle after passing through the slide groove 42 , so that an external force can be manually applied to the connection block 41 through the handle.

[0053] Example 6

[0054] As an optional implementation, refer to Figure 3 A VPX module structure of this embodiment provides a specific structure of a receiving groove 60.

[0055] In this embodiment, the accommodating groove 60 includes a first section 61 and a second section 62 connected to each other, the first section 61 is located on a side close to the protrusion 31, the inner diameter of the first section 61 is smaller than the inner diameter of the second section 62, the part of the limit block 40 is located in the second section 62, the part of the limit block 40 located in the second section 62 is provided with a baffle 44, and a return spring 43 is provided between the baffle 44 and the bottom wall of the second section 62. By dividing the accommodating groove 60 into the first section 61 and the second section 62, the first section 61 can play a role in limiting and guiding the limit member to prevent the limit member from shaking randomly, and the return spring 43 applies a thrust to the limit block 40, so that the limit block 40 can automatically return to its original position.

[0056] Specifically, the cross-sectional shape of the limit block 40 can be circular, and the cross-sectional shapes of the first section 61 and the second section 62 are also circular. The outer diameter of the limit block 40 is adapted to the inner diameter of the first section 61, so that the first section 61 can play a role in limiting and guiding the limit block 40, thereby preventing the limit block 40 from shaking randomly and making abnormal noises during the lateral movement. By arranging a baffle 44 on the limit block 40, and arranging a return spring 43 between the baffle 44 and the bottom wall of the second section 62, the bottom wall of the second section 62 is the inner wall of the notch relative to the accommodating groove 60, and the return spring 43 is always in a compressed state, so that the limit block 40 always has a tendency to move to the left. When the limit block 40 is controlled to move to the right by the connecting block 41, after the pull-out aid 20 is unlocked, it can be automatically ejected under the action of the return spring 43.

[0057] Example 7

[0058] As an optional implementation, refer to Figure 3 A VPX module structure of this embodiment provides a specific structure in which a protrusion 31 contacts a limit block 40 .

[0059] In this embodiment, a first inclined surface 311 is provided on the side of the protrusion 31 away from the limiting groove 32, and the limiting block 40 has a second inclined surface 312 for cooperating with the first inclined surface 311. By providing the first inclined surface 311 and the second inclined surface 312 that cooperate with each other, when the pull-out aid 20 is limited and locked, a horizontal component force can be applied to the limiting block 40 through the contact between the first inclined surface 311 and the second inclined surface 312 to realize that the limiting block 40 automatically enters the accommodating groove 60, so that the limiting block 40 can pass over the protrusion 31 and enter the limiting groove 32. The first inclined surface 311 gradually tilts toward the limiting groove 32 in the direction close to the free end 21 of the pull-out aid 20.

[0060] Specifically, when the pull-out aid 20 is locked, the free end 21 of the pull-out aid 20 moves clockwise in the direction close to the limit groove 32. At this time, the first inclined surface 311 is opposite to the second inclined surface 312. During the continuous movement of the free end 21 of the pull-out aid 20, the first inclined surface 311 contacts the second inclined surface 312, and the protrusion 31 applies horizontal separation to the limit block 40, so that the return spring 43 is compressed, and the limit block 40 is stored to the right in the accommodating groove 60. Then, when the limit block 40 moves to the position of the limit groove 32, the limit block 40 loses the external force of the protrusion 31, and the limit block 40 automatically pops out under the action of the return spring 43, and the limit block 40 enters the limit groove 32 to complete the locking.

[0061] Example 8

[0062] As an optional implementation, refer to Figure 1 and Figure 5 A VPX module structure of this embodiment provides a specific structure of a pull-out aid 20 .

[0063] In this embodiment, a support block 70 is further provided at one end of the ejector 20 hinged to the mounting groove 50. When the free end 21 of the ejector 20 rotates around the junction end, the support block 70 can contact the side wall of the mounting groove 50. The surface of the support block 70 used to contact the side wall of the mounting groove 50 is an arc surface. By providing the support block 70, after the free end 21 of the ejector 20 rotates around the hinge of the ejector 20, the support block 70 plays a supporting role, and the module body 10 is easily plugged in and out through the lever principle.

[0064] The mounting groove 50 is located at the edge of the module body 10, and one side of the mounting groove 50 passes through the outer wall of the module body 10. The side wall of the mounting groove 50 passes through the outer wall of the module body 10, and after the contact protrusion 31 and the limiting block 40 are relatively limited, the free end 21 of the ejection aid 20 can move directly outward.

[0065] Specifically, two extraction aids 20 structures may be symmetrically arranged on both sides of the module body 10 to facilitate the insertion or extraction of the module body 10 as a whole.
