Technical Field

[0001] The utility model belongs to the technical field of double-layer OCP interfaces, in particular to a double-layer OCP interface installation structure. Background Art

[0002] The OCP (Open Compute Project) port is a server communication interface based on open source hardware, designed to improve the interoperability of server, storage and network server systems. The OCP interface is a hardware exchange interface specification with open source code. It provides all the protocols and format specifications required for communication between hardware devices, facilitating information exchange between hardware devices. The OCP port also opens up a new way for data exchange that is different from traditional hardware interfaces.

[0003] The role of the OCP interface is to unify various devices with different functions, such as the Central Processing Unit (CPU), solid-state drive (SSD) and memory, and treat them as a server with stronger overall performance. Therefore, it can make enterprise management easier, more convenient and less costly, while improving the flexibility of data storage, data center and server system management. The OCP interface has: high reusability, good flexibility of use, and high efficiency of management and operation and maintenance.

[0004] Some existing storage project chassis nodes use a double-layer OCP interface structure at the rear to meet a wider range of docking needs; each layer uses 4 OCP interfaces, the 4 OCP interfaces on the lower layer are directly installed on the mainboard, and the 4 OCP interfaces on the upper layer are installed on the lifting board, which is connected to the mainboard through 2 high-density terminals and 2 low-speed connectors. Since the long lifting board is installed parallel to the upper side of the mainboard and the high-density terminals require a large plug-in force, when the lifting board is plugged in and out of the mainboard, it will cause the lifting board to bend and deform, and the left and right plug-ins of the lifting board are not synchronized, which will cause damage to the lifting board and loose matching of the high-density terminals. Utility Model Content

[0005] In the traditional double-layer OCP interface structure, the lifting plate is installed parallel to the upper side of the mainboard, and the high-density terminals require a large plug-in and pull-out force. When the lifting plate and the mainboard are plugged in and out, the lifting plate will bend and deform, and the left and right plug-ins of the lifting plate will not be synchronized, thereby causing damage to the lifting plate and loose fit of the high-density terminals. In order to solve the above problems, the utility model provides a double-layer OCP interface installation structure.

[0006] The utility model is realized by the following technical solutions:

[0007] A double-layer OCP interface installation structure includes a main board and a lifting board.

[0009] A further improvement of the present utility model is that the second lifting board positioning screw is rotatably connected and installed with the lifting board.

[0010] A further improvement of the present utility model is that the lifting board reinforcing frame includes a second frame body with a "J" - shaped cross-section and a first frame body with a "冂" - shaped cross-section; The second frame body is embedded inside the first frame body, and the first frame body and the lifting board are connected and installed through lifting board reinforcing frame positioning screws.

[0011] A further improvement of the present utility model is that a first lifting board positioning screw capable of being screwed with the stud is also passed through the lifting board.

DETAILED DESCRIPTION

[0028] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0029] like Figure 1-7 As shown, an optional embodiment of the utility model discloses a double-layer OCP interface installation structure, including a motherboard 2 that can be positioned and installed in a chassis 1 and a lifting plate 3 arranged on the upper side of the motherboard 2, four OCP interfaces 4 correspondingly arranged in the upper and lower directions are respectively installed on the rear ends of the motherboard 2 and the lifting plate 3, a plurality of studs 10 that can support the lifting plate 3 are positioned and installed on the upper side of the motherboard 2, and the lifting plate 3 and the motherboard 2 are connected through two high-density terminals 11 and two low-speed connectors 12, and the two high-density terminals 11 and the two low-speed connectors 12 are respectively symmetrically arranged on the left and right; a second lifting plate positioning screw 9 that can be screwed and installed with the stud 10 is connected to the lifting plate 3, and a lifting plate reinforcement frame 5 is positioned and installed on the upper side of the lifting plate 3 along its length direction; a knob 7 is rotatably installed on the lifting plate reinforcement frame 5, and a slide plate 8 is installed on the lifting plate reinforcement frame 5 for sliding guidance; a rack is provided on the slide plate 8, a gear 71 meshing with the rack is installed on the knob 7, and a rotating tooth meshing with the rack is provided on the upper part of the second lifting plate positioning screw 9. There are two slide plates 8, and the knob 7 is disposed between the two slide plates 8. The slide plates 8 are symmetrical with respect to the center of the rotation axis of the knob 7. There are two second lifting plate positioning screws 9.

[0030] By attaching and connecting the lifting plate reinforcement frame 5 to the lifting plate 3, the structure of the lifting plate 3 can be strengthened to avoid bending and deformation of the lifting plate 3 under stress; by rotating the operating knob 7, the two second lifting plate positioning screws 9 can be rotated synchronously, so that the second lifting plate positioning screws 9 on both sides can be screwed in or out synchronously, so that the lifting plate 3 can be connected to the main board 2 in parallel (two high-density terminals 11 and two low-speed connectors 12 can be inserted) or unlocked synchronously, thereby effectively avoiding the problem of tilted installation of the lifting plate 3 and ensuring that the high-density terminals 11 and the low-speed connectors 12 are inserted tightly and reliably. The overall structure is simple, easy to use, and practical.

[0031] The two second lifting plate positioning screws 9 are arranged close to the outer sides of the two high-density terminals 11 , so as to effectively ensure the tightness of the connection between the two high-density terminals 11 .

[0032] Among them, Figure 4-5 As shown, the high-density terminal 11 includes a high-density terminal female end 111 connected and installed on the upper side of the mainboard 2 and a high-density terminal male end 112 connected and installed on the lower side of the lifting plate 3, and the low-speed connector 12 includes a low-speed connector female end 121 connected and installed on the upper side of the mainboard 2 and a low-speed connector male end 122 connected and installed on the lower side of the lifting plate 3. Through the plug-in connection between the high-density terminal female end 111 and the high-density terminal male end 112, and through the plug-in connection between the low-speed connector female end 121 and the low-speed connector male end 122, stable communication of the upper four OCP interfaces 4 can be achieved. The reliability of the use of the double-layer OCP interface 4 is ensured.

[0033] Furthermore, the second lifting plate positioning screw 9 is rotatably connected and installed with the lifting plate 3. The second lifting plate positioning screw 9 is riveted to the lifting plate 3 so that the second lifting plate positioning screw 9 can only rotate but cannot move axially. When the second lifting plate positioning screw 9 is unscrewed in the stud 10, the entire lifting plate 3 can be driven to move upward as a whole, thereby realizing the synchronous separation of the high-density terminal 11 and the low-speed connector 12, achieving convenient operation, and effectively avoiding the tilting phenomenon caused by manually lifting the lifting plate 3, thereby avoiding damage to the lifting plate 3, the high-density terminal 11, and the low-speed connector 12. The second lifting plate positioning screw 9 is similar to a captive screw.

[0034] Among them, Figure 2 , 3As shown in FIGS. 6 and 7, the lifting plate reinforcing frame 5 includes a second frame body 52 with a "ji" - shaped cross - section and a first frame body 51 with a "kuang" - shaped cross - section; the second frame body 52 is embedded inside the first frame body 51, and a chute (front - front - side) for guiding the sliding of the slide plate 8 is formed between them. Moreover, the upper side of the second frame body 52 is riveted to fit with the web of the first frame body 51. The first frame body 51 and the lifting plate 3 are connected and installed through 8 lifting - plate reinforcing - frame positioning screws 15. Every four lifting - plate reinforcing - frame positioning screws 15 are distributed around a high - density terminal 11, ensuring the structural reinforcement of the position of the high - density terminal 11. The lifting plate reinforcing frame 5 has a simple structure, good bending resistance, and high strength.

[0035] Among them, as Figure 2 、 3 shown, a first lifting - plate positioning screw 6 capable of being screwed with the stud 10 is also passed through the lifting plate 3. The first lifting - plate positioning screw 6 is provided with two, and is respectively arranged at both ends of the lifting plate 3. After operating the second lifting - plate positioning screw 9 to lock, then tighten the first lifting - plate positioning screw 6; before operating the second lifting - plate positioning screw 9 to loosen, it is necessary to first remove the first lifting - plate positioning screw 6, effectively ensuring the reliable positioning and stability of the lifting plate 3.

[0036] Among them, as Figure 4 、 5 shown, a guide post 13 is positioned and installed on the upper side of the main board 2, and a guide seat 14 that is in guiding cooperation with the guide post 13 is positioned and installed on the lower side of the lifting plate 3. The end of the guide post 13 has a chamfer, and a guide groove with an opening downward is formed on the guide post 13, and the lower edge of the guide groove has a chamfer. Through the insertion of the guide groove on the guide seat 14 and the guide post 13, the precise positioning during the installation of the lifting plate 3 is realized, ensuring the convenience of installing the lifting plate 3. The number of guide posts 13 is two, and they are arranged close to the female end 111 of the high - density terminal and are arranged inside the female end 111 of the high - density terminal, effectively ensuring the precise guiding and positioning of the insertion of the high - density terminal 11.

[0037] Among them, the outer ring of the knob 7 is provided with anti - slip protrusions. It effectively increases the static friction force of pinching the knob 7 and avoids slipping.

[0038] In this double - layer OCP interface installation structure, through the attachment connection between the lifting plate reinforcing frame 5 and the lifting plate 3, the structural reinforcement of the lifting plate 3 can be realized, avoiding the problem of the lifting plate 3 being bent and deformed under force; by operating the knob 7 to rotate, the synchronous rotation of the two second lifting - plate positioning screws 9 can be realized, so that the synchronous screwing in or screwing out of the two second lifting - plate positioning screws 9 on both sides can be realized, and thus the parallel connection (the insertion of the two high - density terminals 11 and the two low - speed connectors 12) or synchronous unlocking of the lifting plate 3 and the main board 2 can be realized, effectively avoiding the problem of the lifting plate 3 being installed obliquely, and ensuring the tight and reliable insertion of the high - density terminal 11 and the low - speed connector 12. The overall structure is simple, easy to use, and has good practicability.
