Furthermore, the different embodiments or examples described in this specification and the features of the different embodiments or examples may be combined and combined by those skilled in the art without contradiction.

In the related art, referring to fig. 1, a conventional general-purpose server 100 'module layout generally includes a hard disk module 102' disposed at a front end of a chassis 101', and an IO interface 103' disposed opposite to a rear end of the front end. Under the layout, the OCP module 104 'in the IO interface 103' is also installed at the tail of the chassis 101', and the interface of the OCP module 104' is external, and after the tail of the chassis 101 'is inserted into the main board of the server 100', the OCP module 104 'is fixed at the tail of the chassis 101' through screws 106 'on the OCP module 104' at the rear window of the chassis 101 'of the server 100'. Then, the cable is plugged in and plugged out and maintained at the tail of the server 100'. It should be noted that, the OCP module 104 'is a pluggable modular interface for the server 100' and the data center device, and is generally used to connect and expand different types of functional boards, such as computing, storage, networking, and acceleration cards. Through the OCP interface, these modules can exchange and communicate data with the motherboard system of the server 100'. As can be seen from fig. 1, when the OCP module 104' is plugged at the tail of the chassis 101', the whole OCP module 104' needs to be pulled out from the server 100', and the space required for plugging is the length dimension (see the double-headed arrow in fig. 1) of the whole OCP module 104', so that the space required for plugging is larger.

In addition, fig. 2 is a schematic diagram of the structure of the motherboard of the OCP module 104' for plugging and unplugging the server 100' in fig. 1, and referring to fig. 2, when the OCP module 104' is fixed at the tail of the chassis 101', only one screw 106' is used, and the screw 106' is installed at the end angle position of the tail of the OCP module 104 '. After the OCP module 104 'is inserted into the chassis 101', the OCP module 104 'is fixed to the rear window of the rear portion of the chassis 101' by screws 106 'on one side of the rear portion of the OCP module 104'. At this time, at the side position where the OCP module 104 'is fixed by the screw 106', the contact gap between the OCP module 104 'and the motherboard of the server 100' is smaller, and the connection is more reliable. However, the single-sided fixation results in a certain degree of inclination of the OCP module 104' at the position abutting against the motherboard of the server 100' after being inserted into the chassis 101 '. Specifically, at the end angle of the other end of the OCP module 104' where the screw 106' is not installed, the gap between the side of the OCP module 104' and the motherboard of the server 100' is larger than the gap between the side of the OCP module 104' where the screw 106' is fixed due to the lack of the limitation of the screw 106 '. That is, the OCP module 104 'can be closely attached to the motherboard of the server 100' on the screw 106 'side, and the OCP module 104' and the motherboard of the server 100 'cannot be inserted in place on the diagonal side of the screw 106'. In view of the above, the fixation of the single-sided screw 106 'results in the OCP module 104' tilting after being installed in place, which reduces the alignment accuracy between the OCP module 104 'and the motherboard of the server 100', and the unstable connection may also cause signal quality degradation, data transmission errors and even equipment failure, with a certain quality hidden trouble.

Furthermore, under the layout of the servers of the whole cabinet, the conventional universal server is used as a blind-plug computing node to be plugged into and pulled out of the whole cabinet, and three buses of water, electricity and signals are integrated at the tail of the cabinet. At this time, the OCP module 104' cannot be screwed at the rear end of the rear window, and the module 104' needs to be placed inside the server for more convenient maintenance of the module 104 '. Therefore, the embodiment of the application provides a built-in OCP fixing device for installing an OCP module inside a server. This fixing device is outside satisfying the demand with built-in server 300 of OCP module, constitute a whole through the guide rail with OCP slide both sides through the bottom plate, preassemble OCP card and integral type OCP slide into an OCP module, and press and rivet two joint pins on quick-witted case base, counterpoint back with the pre-installed OCP module through locating pin and waist slot hole and insert on the server mainboard, the elastic arm lock with integral type OCP slide afterbody both sides is on the joint pin of machine case base at last, realize the reliable contact to OCP module golden finger left and right sides and the on-board connector on the server mainboard, the quality risk of OCP module installation skew has been solved, the plug stroke of OCP module can be shortened simultaneously.

Correspondingly, sliding strips 12 for sliding in cooperation with the guide grooves 23 are also arranged on two opposite sides of the OCP card 1, and the OCP card 1 can be inserted into or pulled out of the OCP slideway 2 through the cooperation of the sliding strips 12 and the guide grooves 23. Fig. 8 is a schematic structural diagram of the OCP chute 2 for inserting and extracting the OCP card 1, referring to fig. 8, the guiding groove 23 has guiding and limiting functions, so that the sliding strips 12 on two sides of the OCP card 1 can slide linearly in the first direction in the guiding rail 22 (refer to the double-headed arrow in fig. 8).

Illustratively, the hook 4 has an integrally formed hook head 41 and hook body 42. The hook head 41 is positioned in the guide groove 23, the hook head 41 is mounted in the guide rail 22 through the hook body 42, and the hook head 41 has an inclined slope toward the sliding direction of the sliding bar 12 so that the sliding bar 12 can be completely slid into the guide groove 23. At this time, the hook head 41 has a trapezoid-like shape. Of course, the hook head 41 may also have a triangular or triangle-like shape, so long as the sliding bar 12 can be locked stably, and the embodiment of the present application is not limited herein.

For example, referring to fig. 8, the hook body 42 of the hook 4 extends along the first direction, the hook body 42 has a certain elasticity, and the guide rail 22 is provided with a yielding space for deformation of the hook body 42, so that the sliding strip 12 presses the inclined slope of the hook head 41 in the process of inserting the sliding strip 12 into the guide groove 23, the hook body 42 deforms towards the direction away from the guide groove 23, so that the hook head 41 can be pressed out of the guide groove 23, until the notch 121 of the sliding strip 12 reaches the position of the hook head 41, the hook 4 is not pressed by the extrusion force of the sliding strip 12, the hook body 42 rebounds, the hook head 41 is clamped into the notch 121, and the sliding strip 12 is locked in the guide groove 23, so that the OCP card 1 is fixed in the OCP slideway 2 to form an OCP module. And the position of the hook body 42 may be located at any side wall position of the guide groove 23, so long as the hook head 41 can be located in the guide groove 23 without affecting the sliding of the sliding bar 12.

In one implementation, the elastic arm 3 has a certain elasticity and may be configured in a U shape, and the U-shaped opening of the elastic arm 3 is disposed toward the bottom of the cabinet 101 in the second direction. Optionally, a bayonet or a mounting clip may be provided on the bottom wall of the chassis 101, and after the golden finger 11 of the OCP module and the onboard connector 303 are inserted in place, the elastic arm 3 is pressed to enable the elastic arm 3 to be snapped into the bayonet or the clip, so as to limit the movement of the OCP module in the first direction. Each guide rail 22 is provided with one elastic arm 3, that is, two elastic arms 3 can ensure that the golden finger 11 of the OCP module is in reliable contact with the on-board connector 303, so that the possibility that the quality risk of the OCP module is generated due to installation deflection is reduced. Meanwhile, the OCP module is fixed in the case 101 in a mode of clamping the elastic arm 3, so that compared with a traditional fixing mode of locking screws, the time for installing and detaching the OCP module is greatly saved, and the plugging efficiency is improved. In addition, in the whole OCP module fixing and disassembling process, the plugging travel is only the distance between the golden finger 11 and the on-board connector 303 on the server main board 105, so that the installation and maintenance time is greatly shortened, the OCP module is conveniently and rapidly plugged by a user, and the usability and maintainability of the server 300 are improved.

As one possible embodiment, with continued reference to fig. 7 and 8, the spring arm 3 includes a first spring plate 31, a second spring plate 32, and a clip plate 33 that are integrally formed.

Referring back to fig. 5 while referring to fig. 10, the fixing device 3021 further includes a snap pin 5. The clamping pin 5 is mounted on the bottom wall of the case 101, and the clamping pin 5 and the clamping plate 33 are mutually clamped and matched to limit the movement of the OCP module in the first direction. For example, under the condition that the golden finger 11 at the other end of the OCP module is inserted into the server motherboard 105, the projection of the clamping plate 33 along the second direction covers a part of the clamping pins 5, that is, the clamping plate 33 and the clamping pins 5 are designed to have a certain interference amount in the depth direction of the clamping pins 5, and then the clamping plate 33 slides towards the clamping pins 5 by pressing the first elastic plate 31 until the clamping plate 33 is clamped on the curved surface side surface of the clamping pins 5.

And one end fixed connection of reinforcing plate 34 is on first elastic plate 31, and the other end fixed connection is on second elastic plate 32 to make reinforcing plate 34, first elastic plate 31 and second elastic plate 32 constitute stable triangle-shaped structure, thereby when joint plate 33 joint on the curved surface side of joint pin 5, reinforcing plate 34 can give second elastic plate 32 a holding power towards joint pin 5, with the frictional force that increases joint plate 33 and joint pin 5, promotes the fixed stability of elastic arm 3 to the OCP module.

As another possible implementation manner, referring to fig. 10, the reinforcing block 35 may be used instead of the reinforcing plate 34, where the reinforcing block 35 is a triangular reinforcing block, and of course, the reinforcing block may be in other shapes such as a trapezoid or a triangle, as long as the strength of the second elastic plate 32 can be improved.

In an implementation manner, with continued reference to fig. 5 and fig. 10, in order to reduce the possibility of jamming in the process that the clamping plate 33 slides into the curved side of the clamping pin 5, an arc-shaped abdication portion 51 is disposed at the end of the clamping pin 5 facing away from the chassis 101, so that the clamping plate 33 can gradually move towards the curved side of the clamping pin 5 along the inclined plane of the arc-shaped abdication portion 51. In order to further improve the stability of the fixing between the clamping plate 33 and the curved surface side of the clamping pin 5, a clamping ring groove 52 is formed in the contact between the clamping pin 5 and the clamping plate 33. Correspondingly, a clamping gap 331 is formed at a portion of the clamping plate 33 in contact with the curved surface side surface of the clamping pin 5 (see fig. 7 herein), and the clamping gap 331 is an annular gap and has the same curvature radius as the clamping ring groove 52, so that the clamping gap 331 can be clamped into the clamping ring groove 52 more tightly.

Illustratively, the bayonet 5 may be mounted to the bottom wall of the chassis 101 by adhesive, bayonet, or screw connection, although this application is not limited in this respect.

Optionally, referring to fig. 5 and fig. 10, in order to further reduce the quality risk of the OCP module tilting after being inserted in place, the fixing device 3021 further includes at least one set of locating pins 6, where the locating pins 6 are mounted on the bottom wall of the chassis 101, each set of locating pins 6 is provided with two locating pins 6, and the two locating pins 6 of the same set are respectively located on two opposite sides of the OCP module in the third direction, and the locating pins 6 abut against the guide rail 22 of the OCP slideway 2, so as to limit the sliding of the OCP slideway 2 in the third direction, and further reduce the possibility of the OCP module tilting. The locating pin 6 may be attached to the bottom wall of the chassis 101 by adhesion, clamping or screwing, which is not limited herein.

Illustratively, referring to fig. 5 and 10, the locating pin 6 has an integrally formed head 61 and shank 62, the head 61 being sized larger than the shank 62. Meanwhile, a kidney-shaped long hole 221 for accommodating insertion of the positioning pin 6 is formed in the guide rail 22, and a length direction of the kidney-shaped long hole 221 is a first direction. A locking convex edge 222 extends towards the center of the kidney-shaped long hole 221 in the kidney-shaped long hole 221, the locking convex edge 222 is arranged in a U shape, and the opening size of the locking convex edge 222 is smaller than the size of the nail head 61 and larger than the size of the handle body 62. The kidney-shaped long hole 221 reserves a space for inserting the pin head 61 of the locating pin 6 into the kidney-shaped long hole 221 at the opening of the clamping convex edge 222, so that the locating pin 6 can be inserted into the kidney-shaped long hole 221, and in the sliding process of the OCP module, the clamping convex edge 222 can slide into the space between the pin head 61 and the bottom of the chassis 101, so that the pin head 61 can also limit the movement of the OCP module in the second direction.

In one possible embodiment, the positioning pins 6 are provided in two groups, that is to say the positioning ceiling has four, and correspondingly the kidney-shaped slot 221 is provided with four. For example, the shank 42 of the hook 4 may be used as a component of one of the kidney-shaped slots 221, that is, the yielding space for deformation of the shank 42 on the guide rail 22 is the kidney-shaped slot 221, so as to reduce the number of holes of the guide rail 22 and improve the stability of the guide rail 22.

In some possible embodiments, after the OCP module is installed inside the chassis 101, other hardware modules may be installed around the OCP module, so that a fixture for pre-installing other hardware modules is installed on the chassis 101. Therefore, the designer may also set up a space for fixture installation on the guide rail 22 according to the layout structure of the hardware modules inside the computing node 302. For example, the kidney-shaped long hole 221 may be designed to be an open structure to form a yielding space for mounting other hardware modules.
