The present application will be further described in detail below with reference to the drawings and detailed description for the purpose of enabling those skilled in the art to better understand the aspects of the present application.
In a first aspect, referring to fig. 1 and 2, an embodiment of the present application provides a circuit board module 100, which is applied to a server. It can be understood that the server includes a chassis 200, the circuit board module 100 is disposed in the chassis 200 to form a supporting and connecting function for the circuit board module 100 through the chassis 200, the chassis 200 can also be used as a protection structural member of the circuit board module 100 to protect the circuit board module 100, so as to prevent dust, water vapor and the like in the external environment of the chassis 200 from entering the chassis 200, affecting the heat dissipation performance of the circuit board 110, and the service performance of the server, thereby improving the data processing performance of the server and the working stability of the server.
In some embodiments, the circuit board module 100 includes a circuit board 110, and the circuit board 110 may be used to electrically connect with electrical components, for example, the circuit board 110 may be provided with a central processing unit (Central Processing Unit, CPU), a memory, etc. to meet the data processing requirements of the server. The memory may be the hard disk 300, etc., which is not specifically required in the embodiment of the present application.
When the hard disk 300 is connected with the circuit board 110, different connection terminals 117 can be arranged on the circuit board 110, and the hard disk 300 is connected with the circuit board 110 through the connection terminals 117, so that stable electric connection between the circuit board 110 and the hard disk 300 is realized, and data processing and signal interaction of the server are more stable.
The types of hard disks 300 are different, and the interfaces of the hard disks 300 are correspondingly different, and the common interfaces of the hard disks 300 include serial interfaces, such as an SAS interface (SERIAL ATTACHED SCSI), a SATA interface (SERIAL ATA), an NVMe interface (NVM Express), and the like. The structure of the connection terminal 117 and the interface of the hard disk 300 in the embodiment of the present application are matched with each other, so that the hard disk 300 is directly mated with the connection terminal 117 through the interface.
In the implementation process, the assembly force between the interfaces of different hard disks 300 and the connection terminals 117 is also different, and by way of example, the assembly force between the hard disks 300 of the SAS interface and the SATA interface and the connection terminals 117 is often 25N, and the assembly force between the hard disks 300 of the nvme interface and the connection terminals 117 is often 59N. Due to the difference in assembly force between the hard disk 300 and the circuit board 110, an abnormal situation of increased assembly force and deformation of the circuit board 110 occurs, and the engagement distance between the interface of the hard disk 300 and the connection terminal 117 is insufficient, so that the electrical connection between the hard disk 300 and the circuit board 110 is abnormal, the speed of the server for retrieving and storing the data of the hard disk 300 is reduced, and the service performance and stability of the server are affected.
In addition, in the case 200, the connection between the circuit board 110 and the inner wall of the case 200 is usually fixed by screws, in some embodiments, the number of screws may be increased, and the fixing points are formed on the walls of the circuit board 110 and the case 200 by a plurality of screws, so as to improve the connection stability between the circuit board 110 and the case 200. However, such a connection may cause a decrease in the installation efficiency and maintenance efficiency of the circuit board 110.
It can be appreciated that the increase of the number of screws and the increase of the screw holes on the circuit board 110 result in the change of the wiring layout of the circuit board 110, and the available area of the wiring of the circuit board 110 is reduced, so that the wiring area of the circuit board 110 needs to be increased to meet the requirement of the server on data processing, the wiring layout is reasonable, the mutual interference between signals is reduced, the reliability and stability of the signal processing of the server are improved, and the heat dissipation efficiency of the circuit board 110 is improved, so that the working temperature of the circuit board 110 is kept in a stable interval, and the service performance of the server is improved. However, as the area of the circuit board 110 increases, and the amount of deformation of the circuit board 110 also changes, which is disadvantageous in terms of miniaturization of the server, and thus the performance of the server is easily deteriorated.
In order to solve the above-mentioned drawbacks, referring to fig. 1 to 6, the circuit board module 100 in the embodiment of the application further includes a first connector 120 and a second connector 130. The first connecting piece 120 and the second connecting piece 130 are arranged at two opposite ends of the circuit board 110 along the first direction (X), so that the circuit board 110 is fixed and limited by the first connecting piece 120 and the second connecting piece 130, the circuit board 110 is prevented from moving along the first direction (X), the connection between the circuit board 110 and the hard disk 300 is facilitated, the problem of abnormal electrical connection between the hard disk 300 and the circuit board 110 caused by the position movement of the circuit board 110 can be prevented, the operation of the server is stable, and the service performance of the server is improved.
In an alternative embodiment, the first connector 120 and the circuit board 110 are connected in a snap-fit manner. In this way, the first connecting member 120 and the circuit board 110 are connected in a clamping manner, so that the number of screws can be reduced, and the installation and maintenance of the circuit board 110 are facilitated, thereby improving the installation efficiency and maintenance efficiency of the circuit board 110. Along with the reduction of the number of the screws, the available area of the circuit board 110 is increased, the size of the circuit board 110 can be reduced, the space occupation ratio of the circuit board 110 is reduced on the basis of meeting the performance of the server, the miniaturization of the server is facilitated, and the production cost of the server can be reduced.
In the embodiment of the application, along the first direction (X), one side of the first connecting piece 120, which is away from the circuit board 110, is connected with the wall of the chassis 200 in a clamping manner, so that the circuit board module 100 and the chassis 200 are conveniently installed and disassembled, the installation difficulty and maintenance difficulty of the server are reduced, and the installation efficiency and maintenance efficiency are improved.
Optionally, the second connector 130 and the circuit board 110 are connected in a clamping manner. In this way, the second connecting member 130 and the circuit board 110 are connected in a clamping manner, so that the number of screws can be reduced, and the installation and maintenance of the circuit board 110 are facilitated, thereby improving the installation efficiency and maintenance efficiency of the circuit board 110. Along with the reduction of the number of the screws, the available area of the circuit board 110 is increased, the size of the circuit board 110 can be reduced, the space occupation ratio of the circuit board 110 is reduced on the basis of meeting the performance of the server, the miniaturization of the server is facilitated, and the production cost of the server can be reduced.
In the embodiment of the application, along the first direction (X), one side of the second connecting member 130 facing away from the circuit board 110 is connected with the wall of the chassis 200 in a clamping manner, so that the circuit board module 100 and the chassis 200 are conveniently installed and disassembled, the installation difficulty and maintenance difficulty of the server are reduced, and the installation efficiency and maintenance efficiency are improved.
It can be appreciated that the first connecting member 120 and the second connecting member 130 are connected to two ends of the circuit board 110 along the first direction (X), and by such arrangement, the stability of the circuit board module 100 is improved, the deformation of the circuit board 110 can be reduced, so that the electrical connection between the hard disk 300 and the circuit board 110 is stable, and the working stability of the server is improved.
It should be noted that, in the embodiment of the present application, the first direction (X) intersects with the thickness direction (Y) of the circuit board 110, that is, the first direction (X) may be the length direction of the circuit board 110 or the width direction of the circuit board 110. The embodiment of the present application is described by taking the first direction (X) along the length direction of the circuit board 110 as an example. Referring to fig. 1, a first direction (X) is defined as X, and a thickness direction (Y) of the circuit board is defined as Y.
In combination with the foregoing embodiment, the first connector 120 and the second connector 130 are connected to the circuit board 110 in a clamping manner, wherein the clamping results are various, and as an alternative embodiment, at least one of the first connector 120 and the second connector 130 has a clamping groove, the first connector 120 is connected to the circuit board 110 through the clamping groove, and the second connector 130 is connected to the circuit board 110 through the clamping groove in the second connector 130. In the embodiment of the present application, the first connecting piece 120 and/or the second connecting piece 130 are connected to the circuit board 110 through corresponding slots, so that the movement of the circuit board 110 is limited by the arrangement of the slots, and the structural stability of the circuit board module 100 is improved. Furthermore, the clamping groove has a simple structure, the first connecting piece 120 and/or the second connecting piece 130 are convenient to connect with the circuit board 110, so that the installation and maintenance of the circuit board module 100 are more convenient, the production of the first connecting piece 120 and/or the second connecting piece 130 is convenient, and the production efficiency of the circuit board module 100 and the server is improved.
Referring to fig. 1,2,3 and 5, as an alternative embodiment, the first connector 120 has a first card slot 121, the first card slot 121 extends along a first direction (X), and the first connector 120 and the circuit board 110 are connected by the first card slot 121.
Illustratively, the first clamping groove 121 extends along the first direction (X), and the notch of the first clamping groove 121 faces the circuit board 110, so that the circuit board 110 shell enters the first clamping groove 121 along the first direction (X) relative to the first connecting member 120, and when the circuit board 110 is maintained, the circuit board 110 only needs to be moved along the first direction (X) toward the side of the second connecting member 130 until the circuit board 110 is disconnected from the first clamping groove 121. Thus, through the arrangement of the first clamping groove 121, the circuit board 110 is mounted without being fixed by screws, so that the circuit board 110 is convenient to mount and dismount, and the mounting and dismounting efficiency of the circuit board module 100 and the server is improved, so that the circuit board module 100 and the server are convenient to maintain. In addition, the number of screws is reduced, the routing usable area of the circuit board 110 can be increased, the structural size of the circuit board 110 is reduced, and the space occupation ratio of the circuit board 110 is reduced, thereby being beneficial to miniaturization and light weight of the server.
It should be noted that, in the embodiment of the present application, the structures of the first card slot 121 and the end portion of the circuit board 110 are mutually adapted, that is, along the first direction (X), the structures of the inner wall of the first card slot 121 and the end surface of the circuit board 110 are mutually matched, and along the second direction (Z), the extension length of the first card slot 121 is the same as the extension length of the end portion of the circuit board 110, so that, by the structural arrangement of the first card slot 121, the circuit board 110 is prevented from moving along the first direction (X), thereby reducing the probability of occurrence of abnormal electrical connection between the circuit board 110 and the hard disk 300 and improving the operational reliability of the server.
Referring to fig. 1,2, 4 and 6, in some embodiments, the second connection member 130 has a second card slot 131, the second card slot 131 extends in the first direction (X), and the second connection member 130 and the circuit board 110 are connected through the second card slot 131.
It should be noted that the structures and functions of the second slot 131 and the first slot 121 are similar, and the structure of the second slot 131 will not be described in detail in this section.
It can be understood that the first connecting member 120 is connected to the circuit board 110 through the first clamping groove 121, the second connecting member 130 is connected to the circuit board 110 through the second clamping groove 131, and two ends of the circuit board 110 are respectively located in the corresponding first clamping groove 121 and the corresponding second clamping groove 131, so that the movement of the circuit board 110 along the second direction (Z) can be limited by the first clamping groove 121 and the second clamping groove 131, and the rotation of the circuit board 110 around the axis parallel to the first direction (X) can be limited, thus, after the hard disk 300 and the circuit board 110 are connected, the circuit board 110 is prevented from being deformed and turned due to the force applied by the hard disk 300.
In the embodiment of the present application, the first direction (X), the second direction (Z), and the thickness direction (Y) of the circuit board 110 are perpendicular to each other. The first direction (X) is along the length direction or the width direction of the circuit board 110, and the second direction (Z) is along the width direction or the length direction of the circuit board 110. In connection with the foregoing, the embodiment of the present application will be described by taking the first direction (X) along the length direction of the circuit board 110 and the second direction (Z) along the width direction of the circuit board 110 as an example. Referring to fig. 1, the second direction (Z) is defined as Z.
Furthermore, in an alternative embodiment of the present application, only the first connecting member 120 has the first slot 121, or only the second connecting member 130 has the second slot 131, or the first connecting member 120 has the first slot 121 and the second connecting member 130 has the second slot 131.
In some embodiments, at least one of the first and second card slots 121 and 131 has a stopper, the stopper of the first card slot 121 is stopped at an end of the circuit board 110, and the stopper of the second card slot 131 is stopped at an end of the circuit board (110).
Illustratively, the stop may be a raised structure, a recessed channel structure, etc., which is not required by embodiments of the present application.
Alternatively, the first card slot 121 has a first stop portion 1211, and the first stop portion 1211 is located at a side of the first card slot 121 facing the circuit board 110 along the first direction (X) and stops at an end of the circuit board 110.
In some embodiments, referring to fig. 1, 2, 3 and 5, along the thickness direction (Y) of the circuit board 110, the first stopping portion 1211 may be convexly disposed with respect to the groove wall of the first card groove 121, that is, the first stopping portion 1211 may be a protrusion structure, a boss structure, a step structure, or the like, which is not required in the embodiment of the present application. In the first direction (X), the first stop 1211 matches the shape of the end of the circuit board 110, so that the movement of the circuit board 110 along the first direction (X) is better limited by the stop cooperation of the first stop 1211 and the circuit board 110, so that the circuit board module 100 is kept stable relative to the chassis 200, thereby improving the operation stability and reliability of the server. It can be appreciated that, by the arrangement of the first stop portion 1211, the first stop portion 1211 and the circuit board 110 form a stop connection relationship in a face-to-face manner, which not only limits the movement of the circuit board 110, but also facilitates the installation of the circuit board 110 and the first connector 120, thereby improving the installation efficiency and maintenance efficiency of the circuit board module 100 and the server.
It should be noted that, along the second direction (Z), the extension length of the first stop portion 1211 may be equal to or less than the extension length of the circuit board 110, which is not limited in the embodiment of the present application.
Alternatively, referring to fig. 1, 2,4 and 6, the second card slot 131 has a second stopping portion 1311, and the second stopping portion 1311 is located at a side of the second card slot 131 facing the circuit board 110 along the first direction (X) and stops at an end of the circuit board 110.
It should be noted that the structure and function of the second stop portion 1311 in the embodiment of the present application are similar to those of the first stop portion 1211, which is not described in detail in this section.
The circuit board 110 has various structures, and referring to fig. 1,2 and 8, in an alternative embodiment of the present application, the circuit board 110 has a notch 111, and the notch 111 is located at an end of the circuit board 110 facing the second card slot 131 along the first direction (X). In order to promote the connection stability of the circuit board 110 and the second connector 130 through the second clamping groove 131, the shapes of the notch 111 and the second stopping portion 1311 in the embodiment are matched with each other, and the second stopping portion 1311 and the notch 111 are matched and connected to stop the circuit board 110.
Along the second direction (Z), the extension length of the second stop portion 1311 may be less than or equal to the extension length of the notch 111, so that the circuit board 110 and the second stop portion 1311 are cooperatively connected, thereby improving the assembly efficiency of the circuit board module 100. Meanwhile, the second stop part 1311 and the notch 111 cooperate to form a positioning function for the installation of the circuit board 110, so that the situation that the circuit board 110 is deformed and damaged due to the cooperation deviation of the circuit board 110 and the second connecting piece 130 is prevented, and the assembly efficiency of the circuit board module 100 is further improved.
In some embodiments, the extension length of the second stopper 1311 may be smaller than the extension length of the notch 111 or greater than the extension length of the notch 111 in the thickness direction (Y) of the circuit board 110.
When the extension length of the second stop portion 1311 is smaller than the extension length of the notch 111 in the thickness direction (Y) of the circuit board 110, the second stop portion 1311 still cooperates with the notch 111 to form a stop function and a positioning function of the circuit board 110, but the circuit board 110 is easy to shake or misplug, and even the circuit board 110 is deformed.
When the extension length of the second stop portion 1311 is greater than the extension length of the notch 111 along the thickness direction (Y) of the circuit board 110, the second stop portion 1311 may cause an increase in the slot space of the second slot 131, so that the circuit board 110 may easily shake, and may also cause deformation caused by uneven stress of the circuit board 110. Furthermore, the slot-shaped space of the second slot 131 increases, the structural size of the second connector 130 increases, and the space ratio of the second connector 130 increases, which is not beneficial to reducing the space ratio of the circuit board module 100 and the server.
Therefore, in the embodiment of the present application, along the thickness direction (Y) of the circuit board 110, the extension length of the second stop portion 1311 is equal to the extension length of the notch 111, so that the structure of the circuit board module 100 is stable through the cooperation of the second stop portion 1311 and the notch 111, and the performance degradation of the server caused by the deformation of the circuit board 110 is avoided.
