[0042] The plug-in module provided in the present application can realize an effective anti-fool mechanism in a limited space to meet the high-density and high-precision requirements of high-performance storage servers.

[0044] like Figures 1 to 4 As shown, the T-shaped stop hole 12 is closer to the opening of the sub-accommodating cavity than the second avoidance hole 11. In this way, when the node box 20 is installed incorrectly, the T-shaped elastic hook 22 cooperates with the T-shaped stop hole 12 first, so that most of the node box 20 can still be exposed outside the sub-accommodating cavity, which is convenient for timely removal.

[0045] like Figures 1 to 4 As shown, the tail of the T-shaped elastic hook 22 faces the bottom surface of the sub-accommodating cavity, and the head of the T-shaped elastic hook 22 faces the cavity opening of the sub-accommodating cavity; the narrow end of the T-shaped stop hole 12 faces the bottom surface of the sub-accommodating cavity, and the wide end of the T-shaped stop hole 12 faces the cavity opening of the sub-accommodating cavity.

[0047] like Figure 5 As shown, the T-shaped elastic hook 22 includes a fixed plate 221, a fastener and an elastic movable plate 222, wherein a positioning hole 2211 is provided on the fixed plate 221; the fastener passes through the positioning hole 2211 and is connected to the side wall of the node box 20 to fix the fixed plate 221 on the side wall of the node box 20; the first end of the elastic movable plate 222 is connected to the fixed plate 221, and the second end of the elastic movable plate 222 forms the head of the T-shaped elastic hook 22, and the fixed plate 221 and part of the elastic movable plate 222 form the tail of the T-shaped elastic hook 22. In this way, by setting the T-shaped elastic hook 22 to a structural form including the fixed plate 221, the fastener and the elastic movable plate 222, the installation stability of the T-shaped elastic hook 22 is ensured, and the T-shaped elastic hook 22 can play an effective foolproofing effect.

[0048] Furthermore, if Figure 5As shown, the elastic movable plate 222 includes a first plate body 2221 and a second plate body 2222, wherein the first end of the first plate body 2221 is connected to the fixed plate 221; the second plate body 2222 is perpendicular to the first plate body 2221, and the second plate body 2222 is connected to the second end of the first plate body 2221, two first hooks 100 are symmetrically arranged on both sides of the second end of the first plate body 2221, and two second hooks 200 are symmetrically arranged on both sides of the second plate body 2222, and the first hooks 100 and the second hooks 200 on the same side are arranged with a distance between them.

[0049] like Figure 5 As shown, the first hook 100 is triangular in shape, and the side of the first hook 100 facing away from the second plate body 2222 has an outer snap guide surface 101 and an outer snap locking surface 102; and there is a smooth transition between the outer snap guide surface 101 and the outer snap locking surface 102; the outer snap guide surface 101 extends obliquely toward the side of the first plate body 2221 and in a direction away from the second plate body 2222, and the outer snap locking surface 102 extends obliquely toward the side of the first plate body 2221 and in a direction away from the second plate body 2222; there is a first angle A between the outer snap guide surface 101 and the surface of the second plate body 2222 facing the first avoidance hole 21, and there is a second angle B between the outer snap locking surface 102 and the surface of the second plate body 2222 facing the first avoidance hole 21; wherein, 0<A<90°, 90<B<180°.

[0050] like Figure 5 As shown, the second hook 200 is trapezoidal in shape, and the side of the second hook 200 facing away from the first plate body 2221 has a first planar section 201, an inner hook rounded transition surface 202, a second planar section 203, and an inner hook guide surface 204 that are connected to each other. The first planar section 201 is perpendicular to the plane where the first plate body 2221 is located, the second planar section 203 is parallel to the plane where the first plate body 2221 is located, and the inner hook guide surface 204 extends obliquely along the direction away from the first planar section 201 and gradually approaches the first plate body 2221.

[0051] It should be noted that in this application, Figures 1 to 4As shown, the chassis shell 10 includes a box body 13 and two support plates 14, wherein the box body 13 has a second accommodating cavity; the two support plates 14 are respectively arranged at the opposite side cavity walls of the second accommodating cavity, and the opposite side surfaces of the two support plates 14 and part of the cavity wall of the second accommodating cavity form a first accommodating cavity; wherein each support plate 14 is arranged at a distance from the cavity wall of the second accommodating cavity on the corresponding side, and the support plate 14 is provided with a second avoidance hole 11 and a T-shaped stop hole 12. In this way, it is avoided to directly open the second avoidance hole 11 and the T-shaped stop hole 12 on the box body 13, and while ensuring the overall structural strength of the box body 13, it can also ensure the foolproof reliability between the chassis shell 10 and the node box 20.

[0052] It should be noted that, in the present application, the T-shaped elastic hook 22 is fixed to the node box 20 through the fixing plate 221, and extends out of the first avoidance hole 21, and normally enters the second avoidance hole 11 (a small amount of space is sufficient). The positions of the T-shaped elastic hook 22 and the first avoidance hole 21 of the adjacent node boxes 20 are staggered. The staggered distribution in the present application can refer to Figure 2 As shown, the T-shaped elastic hook 22 and the first avoidance hole 21 of the node box 20 located at the top are both arranged close to the top, and the T-shaped elastic hook 22 and the first avoidance hole 21 of the node box 20 located at the bottom are both arranged close to the bottom, and the adjacent second avoidance hole 11 and T-shaped stop hole 12 on the support plate 14 are also correspondingly staggered, which can prevent mistakes in case of wrong insertion.

[0053] It should be noted that, in the present application, the node box 20 is plugged in and out smoothly: Figure 5 and Figure 6 As shown, when the node box 20 is outside, the T-shaped elastic hook 22 extends out of the first avoidance hole 21. When the node box 20 is inserted into the sub-accommodation cavity, the inner hook guide surface 204 contacts and squeezes the support plate body 14 (the outer buckle guide surface 101 at the far end is tilted), and the T-shaped elastic hook 22 retreats into the first avoidance hole 21. When the node box 20 continues to be inserted to the bottom, the T-shaped elastic hook 22 returns to its position under the action of elastic force, extends out of the first avoidance hole 21, and finally enters the second avoidance hole 11. At this time, the T-shaped elastic hook 22 returns to its natural state to ensure the elasticity of the T-shaped elastic hook 22. When the node box 20 is pulled out, the outer buckle guide surface 101 and the inner hook rounded transition surface 202 sequentially squeeze the second guide structure 111, and the T-shaped elastic hook 22 retreats into the first avoidance hole 21. In this way, the node box 20 can be pulled out smoothly.

[0054] It should be noted that, in the present application, the node box 20 realizes plug-in and pull-out fool-proofing: Figure 7As shown, when the node box 20 is inserted into the sub-accommodation cavity, the inner hook guide surface 204 contacts and squeezes the support plate body 14 (the outer buckle guide surface 101 at the far end is tilted). When continuing to insert into the T-shaped stop hole 12, the inner hook guide surface 204 is no longer stressed and cannot be tilted, and the outer buckle locking surface 102 directly hits the stop edge 122, achieving the purpose of foolproofing. When pulling out, the outer buckle guide surface 101 and the inner hook rounded transition surface 202 squeeze the first guide structure 121 in sequence, and the T-shaped elastic hook 22 retreats into the first avoidance hole 21. In this way, the node box 20 can be pulled out smoothly.

[0055] In summary, the T-shaped elastic hook 22 cooperates with the first avoidance hole 21 to be directly plugged in and out without any impact, and the T-shaped elastic hook 22 cooperates with the T-shaped stop hole 12 to achieve the effect of stopping and preventing mistakes.

[0056] It should be noted that in the present application, under the condition of the height space limit of the plug-in module, the position dislocation distribution of the T-shaped elastic hook 22 and the T-shaped stop hole 12 of the adjacent nodes cannot be achieved. The combination of large and small T-shaped hooks and large and small T-shaped holes is an effective solution to achieve foolproofing, as follows:

[0057] The first node box 20 can be plugged in and out smoothly: Figure 8 As shown, when the node box 20 is outside, the T-shaped elastic hook 22 and the second T-shaped elastic hook 22 (the larger T-shaped elastic hook 22) extend out of the first avoidance hole 21. When the node box 20 is inserted into the sub-accommodation cavity, the inner hook guide surface 204 contacts and squeezes the support plate 14 (the outer buckle guide surface 101 at the far end is tilted), and the second T-shaped elastic hook 22 retreats into the first avoidance hole 21.

[0058] When the first node box 20 continues to be inserted into the first T-shaped stop hole 12 (the larger T-shaped stop hole 12), there is no stopping effect because the first T-shaped stop hole 12 is much larger than the outer snap guide surface 101. After being inserted to the bottom, it returns to its position under the action of elastic force, extends out of the first avoidance hole 21, and finally enters the second avoidance hole 11. At this time, the T-shaped elastic hook 22 returns to its natural state to ensure the elasticity of the T-shaped elastic hook 22. When the node box 20 is pulled out, the outer snap guide surface 101 and the inner hook rounded transition surface 202 squeeze the second guide structure 111 and the first guide structure 121 in sequence, and the T-shaped elastic hook 22 retreats into the first avoidance hole 21. In this way, the node box 20 can be pulled out smoothly.

[0059] When the second node box 20 (with a large T-shaped hook) continues to be inserted into the T-shaped stop hole 12, there is no stopping effect because the size of the stop edge 122 of the first T-shaped stop hole 12 is larger than the second T-shaped stop hole 12. After being inserted to the bottom, it returns to its position under the action of elastic force, extends out of the first avoidance hole 21, and finally enters the second avoidance hole 11. At this time, the T-shaped elastic hook 22 returns to its natural state to ensure the elasticity of the T-shaped elastic hook 22. When the node box 20 is pulled out, the outer buckle guide surface 101 and the inner hook rounded transition surface 202 sequentially squeeze the second guide structure 111 and the first guide structure 121 of the T-shaped stop hole 12, and the second T-shaped elastic hook 22 retreats into the first avoidance hole. In this way, the second node box 20 can be pulled out smoothly.

[0060] The node box 20 realizes foolproofing: Fig. 9 As shown, when the node box 20 (equipped with a large T-shaped hook) continues to be inserted into the first larger T-shaped stop hole 12, the outer buckle guide surface 101 hits the stop edge 122 of the larger T-shaped stop hole 12, achieving a fool-proof effect.

[0061] Beneficial effects brought by the technical solution of the present invention:

[0062] (1) By installing an elastic clip on the plug-in module instead of a fixed PIN solution, the long hole is prevented from damaging the structural strength of the frame around the plug-in module. The strength and precision requirements of the frame around the plug-in module are met, and the performance of the equipment during operation and maintenance is improved.

[0063] (2) Through the staggered arrangement of T-shaped holes and avoidance square holes, smooth plugging and unplugging and fool-proof operation of the plug-in module can be completed.

[0064] (3) Through the combination of large and small T-shaped holes and large and small T-shaped hooks, the smooth plug-in and pull-out and fool-proof operation of the plug-in module in a very small space can be completed.

[0065] The key technical points and points to be protected of the present invention are:

[0066] 1. Following the innovative principle of turning hard into soft, the fixed PIN is changed into an elastic buckle, which does not destroy the structural strength of the frame around the plug-in module with a long anti-fool travel, and meets the strength and accuracy requirements of high-precision plug-in modules (such as node boxes).

[0067] 2. The combination of the guide edge and the elastic hook ensures smooth plugging and unplugging of the plug-in module (such as a node box).

[0068] 3. Through the staggered arrangement of T-shaped hooks and T-shaped holes, the fool-proof operation of plugging and unplugging modules (such as node boxes) is completed.

[0069] 4. Through the combination of large and small T-shaped hooks and large and small T-shaped holes, fool-proof operation of plugging and unplugging modules (such as node boxes) in extremely small spaces can be achieved.

[0070] 5. By arranging the elastic hook on the plug-in module, the space requirement for the surrounding frame of the plug-in module is reduced.

[0071] 6. By setting the avoidance hole, the elastic hook is kept in a natural state for a long time, ensuring the elasticity of the elastic hook.
