Description

An electronic device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on July 6, 2023, with application number 202321770235.X and application name “An Electronic Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of electronic equipment, and in particular to an electronic equipment. Background Art

[0003] As products continue to evolve, server speeds have significantly increased. However, for high-speed male and female connector mating architectures, the large number of components involved and the long dimensional chain, limited by the machining tolerances of these components, means the mating tolerances are large, making it difficult to meet the precision requirements for high-speed connector mating.

[0004] Utility Model Content

[0005] An embodiment of the present application provides an electronic device, which adopts a direct stopping method in the design of two structural parts that need to be matched, namely the first functional module and the second functional module, by transferring the structural stop surface, thereby reducing the number of structural parts involved in the connector plug-in and having a shorter dimension chain. In this way, by shortening the dimension chain, the tolerance of the system structural parts is reduced, which helps to improve the matching accuracy of the connector.

[0006] An embodiment of the present application provides an electronic device, which includes: a chassis; a first functional module fixedly connected to the chassis within the chassis; a first connector arranged on the first functional module within the chassis; a second functional module arranged within the chassis; and a second connector arranged on the second functional module within the chassis; and at least one locking fitting portion is provided on the first functional module, and at least one locking member is provided on the second functional module, and when the locking member is locked with the corresponding locking fitting portion, the first connector and the second connector are pluggable and connected.

[0007] The electronic device of the embodiment of the present application is configured such that the second functional module is movably arranged in the chassis, so that when the locking member and the locking fitting portion are locked, the second functional module can be moved toward the first functional module, thereby achieving pluggable connection between the first connector and the second connector; when the locking member and the locking fitting portion are unlocked, the second functional module can be moved away from the first functional module, thereby achieving separation of the first connector and the second connector, thereby achieving direct stop design of the two structural parts that need to be matched, namely the first functional module and the second functional module, through the transfer of the structural stop surface, reducing the number of structural parts involved in the connector plug-in, and having a shorter dimension chain. In this way, the tolerance of the system structural parts is reduced by shortening the dimension chain, and the gap between the two connectors is reduced, which helps to improve the matching accuracy of the connector.

[0008] In one possible implementation, the locking portion includes a threaded hole; the second functional module is provided with a through hole; the locking member includes a screw and a flange; the screw is disposed within the through hole and passes through the through hole from the end of the screw facing the threaded hole to be threadedly connected to the threaded hole; the flange is disposed at the end of the screw facing away from the first functional module. Thus, when the screw is screwed into the threaded hole, the flange can drive the second functional module and the second connector toward the first functional module, thereby achieving a pluggable connection between the second connector and the first connector with high matching accuracy.

[0009] In one possible implementation, the flange is located on the other side of the second functional module away from the first functional module and engages with the second functional module at the periphery of the through-hole. Alternatively, the through-hole is a stepped hole, and the flange of the screw engages with the stepped portion of the stepped hole. In other words, the screw can extend through the entire second functional module, in which case the flange is located on the other side of the second functional module away from the first functional module, making it easier for operators to operate the locking member. Alternatively, the screw can extend through a portion of the second functional module, in which case the flange engages with the stepped portion of the stepped hole. This reduces the length of the screw, helping to reduce processing difficulty and save costs.

[0010] In one possible implementation, the locking member further includes a limiting structure disposed on the screw rod on a side of the second functional module facing the first functional module, the limiting structure being configured to prevent the locking member from falling out of the through-hole. Because the limiting structure is larger than the through-hole in the second functional module, this prevents the locking member from moving within the through-hole toward the flange and falling out of the through-hole.

[0011] In one possible implementation, the locking member further includes an elastic member disposed on the screw between the limiting structure and the second functional module. Since the elastic member is disposed between the limiting structure and the second functional module, the screw is prevented from reciprocating in the through hole of the second functional module.

[0012] In one possible implementation, the electronic device further includes: a backplane, located between the first functional module and the second functional module, and fixedly connected to the chassis, the backplane being provided with a first through-hole, and the first connector and the second connector being pluggable and connected at the first through-hole. When the first functional module and the second functional module are fixed separately to achieve pluggable connection between the first connector on the first functional module and the second connector on the second functional module, when the backplane is set between the first functional module and the second functional module, the difficulty of assembly will increase. In the solution of the embodiment of the present application, the first functional module and the second functional module are designed in a direct stop manner. When the backplane is set between the first functional module and the second functional module, the difficulty of assembly is small and the matching accuracy is high.

[0013] In one possible implementation, the back panel is provided with at least one second through-hole, through which the locking member passes to engage with the locking engagement portion. Thus, when the back panel is relatively large, providing the second through-hole in the back panel for the locking member to pass through allows the locking member to engage with the locking engagement portion.

[0014] In one possible implementation, the first functional module includes a first circuit board and a first structural member provided on the first circuit board, and the locking fitting portion is provided on the first structural member; and / or the second functional module includes a second circuit board and a second structural member provided on the second circuit board, and the locking member is provided on the second structural member. That is, in order to facilitate the setting of the locking fitting portion, a first structural member may be provided on the first circuit board, the first structural member may be a plate body, and a threaded hole may be provided on the plate body as the locking fitting portion; in order to facilitate the setting of the locking member, a second structural member may be provided on the second circuit board, the second structural member may be a plate body, and illustratively, two plate bodies may be provided on the second circuit board, each plate body may be provided with a through hole, and the locking member may be provided in the through holes of the two plate bodies.

[0015] In one possible implementation, the first connector is provided with the locking members on both sides along the width direction; and the second connector is provided with the locking mating portions on both sides along the width direction corresponding to the locking members, with the width direction being perpendicular to the arrangement direction of the first and second connectors. In this way, the locking members and the locking mating portions can reliably connect the first and second functional modules, thereby achieving a more stable connection and higher matching accuracy between the first and second connectors.

[0016] In one possible implementation, the first and second connectors are high-speed connectors. High-speed connectors require high matching accuracy when plugged together. In the embodiments of this application, the first and second functional modules are designed with direct stoppers, resulting in high matching accuracy when plugged together, meeting the matching accuracy requirements of high-speed connectors. Alternatively, the first and second connectors can be low-speed connectors if necessary.

[0017] Other features and advantages of the present invention will be described in detail in the subsequent specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Figure 1 is a schematic diagram of the structure of an electronic device. The electronic device may be a server. As shown in Figure 1, the electronic device includes a chassis 10, a backplane 20, a functional module A, a connector L1, a functional module B, and a connector L2. The first end of the chassis 10 has a first opening, and the functional module A is installed in the chassis 10 through the first opening of the chassis 10. In addition, the first end of the chassis 10 is provided with a first fixing structure G1, and the functional module A is provided with a first wrench (not shown in the figure). The first wrench and the first fixing structure G1 are limited and cooperated to fix the position of the functional module A. The second end of the chassis 10 has a second opening, and the functional module B is installed in the chassis 10 through the second opening of the chassis 10. The second end of the chassis 10 is provided with a second fixing structure G2, and the functional module B is provided with a second wrench (not shown in the figure). The second wrench and the second fixing structure G2 are limited and cooperated to fix the position of the functional module B. The backplane 20 is located between the functional module A and the functional module B and is fixedly connected to the chassis 10. Furthermore, a through hole is provided on the back plate 20 , and the connector L1 and the connector L2 can be plugged and connected at the through hole.

[0027] In the above scheme, functional module A is fixed separately to chassis 10, and functional module B is fixed separately to chassis 10. Direct stop cannot be performed between connector L1 and connector L2. In addition, since the number of assembly parts involved in the front-to-back plug-in of connector L1 and connector L2 is large, the assembly parts include, for example, a first fixing structure G1, a first wrench, functional module A, connector L1, functional module B, connector L2, a second wrench, and a second fixing structure G2. The dimension chain formed by these assembly parts is long, and there are position tolerances and shape tolerances between adjacent connected parts. The value of these multiple tolerances is large after superposition. Furthermore, in order to avoid interference between connector L1 and connector L2, installation space is also reserved when connector L1 and connector L2 are plugged in and mated, resulting in a large gap between connector L1 and connector L2 after mating, which is not conducive to meeting the high-precision matching requirements of the system. Among them, connector L1 and connector L2 can be high-speed male and female connectors, which have high matching accuracy requirements.

[0028] In view of this, an embodiment of the present application provides an electronic device. The electronic device of the embodiment of the present application, in the front and rear plug-in functional modules, the two structural parts that need to be matched, namely the first functional module and the second functional module, are designed to adopt a direct stop method through the transfer of the structural stop surface. The number of assembly parts involved is small, and the size chain of the connector matching is short, which helps to reduce the tolerance of the system structural parts, so that the matching clearance between the connectors is reduced, and the high-precision matching requirements of the system are met. Among them, the electronic device can be a server, that is, the solution of the embodiment of the present application can be applied to the server architecture, for example, in the product architecture where the front and rear functional modules are matched through high-speed connectors.

[0029] Figure 2 is a schematic structural diagram of an electronic device provided in an embodiment of the present application. As shown in Figure 2, the electronic device includes a chassis 1, a first functional module Z11, a first connector Z12, a second functional module Z21 and a second connector Z22. The first functional module Z11 is fixedly connected to the chassis 1 inside the chassis 1. For example, a fixed structure G is provided on the chassis 1, and a wrench (not shown in the figure) can be provided on the first functional module Z11, and the wrench is limitedly matched with the fixed structure G to fixedly connect the first functional module Z11 to the chassis 1. The first connector Z12 is provided on the first functional module Z11 inside the chassis 1. The second functional module Z21 is movably provided in the chassis 1. The second connector Z22 is provided on the second functional module Z21 inside the chassis 1, and the second connector Z22 can be pluggably connected to the first connector Z12.

[0030] Furthermore, the first functional module Z11 is provided with at least one locking mating portion P, and the second functional module Z21 is provided with at least one locking member S. When each locking member S is locked with the corresponding locking mating portion P, the second functional module Z21 can be moved toward the first functional module Z11, thereby achieving a pluggable connection between the first connector Z12 and the second connector Z22. Furthermore, when each locking member S is unlocked from the corresponding locking mating portion P, the second functional module Z21 can be moved away from the first functional module Z11, thereby separating the first connector Z12 and the second connector Z22.

[0031] In the embodiment of the present application, by movably positioning the second functional module Z21 within the chassis 1, the first connector Z12 and the second connector Z22 can be tightly connected when the locking member S is locked with the locking mating portion P, thereby reducing the gap between the connectors. This design utilizes a direct stop for the two mating components, the first and second functional modules, reducing the number of assembly parts involved and shortening the dimensional chain for connector mating. This helps reduce the tolerances of the system's structural components and meets the system's high-precision matching requirements.

[0032] The first connector Z12 and the second connector Z22 can be high-speed connectors. In some examples, the first connector Z12 is provided with locking members S on both sides along the width direction; and the second connector Z22 is provided with locking mating portions P on both sides along the width direction corresponding to the locking members S, with the width direction being perpendicular to the arrangement direction of the first connector Z12 and the second connector Z22.

[0033] Furthermore, the electronic device may also include a backplane 2. The backplane 2 is located between the first functional module Z11 and the second functional module Z21 and is fixedly connected to the chassis 1. For example, positioning holes are provided on the side of the backplane 2, and positioning posts are provided on the sidewalls of the chassis 1 corresponding to the positioning holes. The positioning posts mate with the positioning holes and secure the position of the backplane 2. The backplane 2 is provided with a first through-hole, through which the first connector Z12 and the second connector Z22 are pluggable and connected.

[0034] In addition, a second through hole may be provided on the back plate 2 , and the locking member S may pass through the second through hole and be locked with the locking fitting portion P, or the locking member S may be locked with the locking fitting portion P on the outer side of the back plate 2 .

[0035] In some embodiments, a third connector (not shown in the figure) is also provided on the first functional module Z11, and a fourth connector (not shown in the figure) is provided on the backplane 2. The third connector and the fourth connector are pluggable, so that the backplane 2 and the first functional module Z11 can communicate through the third connector and the fourth connector.

[0036] In some other embodiments, a fifth connector (not shown in the figure) is also provided on the second functional module Z21, and a sixth connector (not shown in the figure) is provided on the backplane 2. The fifth connector and the sixth connector are pluggable, so that the backplane 2 and the second functional module Z21 can communicate through the fifth connector and the sixth connector.

[0037] Continuing to refer to Figure 2, exemplarily, the locking fitting portion P may include a threaded hole; a through hole is provided on the second functional module Z21, and the locking member S includes a screw S1 and a flange S2, the screw S1 is provided in the through hole and passes through the through hole from the end of the screw S1 facing the threaded hole to be threadedly connected with the threaded hole, and the flange S2 is provided at the end of the screw S1 away from the first functional module Z11.

[0038] In Figure 2, the flange S2 of the screw S1 is located on the other side of the second functional module Z21 away from the first functional module Z11, and is limitedly engaged with the second functional module Z21 at the periphery of the through hole. In some examples, the second functional module Z21 may include a second circuit board and a second structural member provided on the second circuit board, and the locking member S is provided on the second structural member. For example, the second structural member may be a plate body, and two second structural members may be provided on the second circuit board at intervals, one of the two structural members may be located on the side of the second circuit board facing the back plate 2, and the other may be located on the other side of the second circuit board away from the back plate 2, a through hole is provided on each second structural member, and the screw S2 may be provided through the through holes on the two second structural members.

[0039] In other embodiments, one of the two second structural members spaced apart on the second circuit board may be located on the side of the second circuit board facing the back panel 2, while the other may be located between the side of the second circuit board facing the back panel 2 and the other side away from the back panel. The screw S2 may be inserted through the through holes in the two second structural members. In this case, the length of the locking member S can be reduced. Furthermore, the locking member S can be locked or unlocked with the locking mating portion P using a tool such as a screwdriver.

[0040] Furthermore, as shown in Figure 2 , the locking member S may also include a limiting structure S3, which is disposed on the screw rod S1 on the side of the second functional module Z21 facing the first functional module Z11. The limiting structure S3 is used to prevent the locking member S from falling out of the through hole. For example, the limiting structure S3 may be a washer or a retaining spring, which may be sleeved onto the screw rod and fixedly connected thereto.

[0041] Furthermore, to prevent the screw S1 from reciprocating within the through-hole, the locking member S may also include an elastic member S4, which is disposed on the screw S1 between the retaining structure S3 and the second functional module Z21. One end of the elastic member S4 can abut against and connect to the retaining structure S3, while the other end of the elastic member S4 can abut against and connect to the second functional module Z21. For example, the elastic member S4 can be a spring, which can be mounted on the outside of the screw S1.

[0042] Furthermore, the first functional module Z11 may include a first circuit board and a first structural member disposed on the first circuit board. A locking portion P, such as a threaded hole, may be disposed on the first structural member. For example, the first structural member is disposed on the side of the first circuit board facing the second functional module Z21. The first structural member may be a plate and may be vertically connected to the first circuit board. The first structural member may be provided with a threaded hole, i.e., the locking portion P, corresponding to the screw.

[0043] Figure 3 is a schematic diagram of the structure of another electronic device provided by an embodiment of the present application. Unlike the electronic device shown in Figure 2, the through hole in Figure 3 is a stepped hole, with the flange S2 of the screw S1 engaging with the stepped portion of the stepped hole. This reduces the length of the locking member S, helping to reduce manufacturing difficulty and save costs. Furthermore, the locking member S can be locked or unlocked with the locking mating portion P using a tool such as a screwdriver.

[0044] Compared with the solution of fixing the two functional modules separately as shown in Figure 1, as shown in Figures 2 and 3, the solution of the embodiment of the present application adopts a direct stopping method in the design of the two structural parts that need to be matched, namely the first functional module and the second functional module, through the transfer of the structural stop surface, which helps to improve the matching accuracy of the connector.

[0045] To sum up, the electronic device of the embodiment of the present application provides a long-distance locking method, which adopts a long-distance locking solution in the front-to-back plug-in system, reduces the number of structural parts involved in the connector plug-in, and has a shorter dimension chain. In this way, by shortening the dimension chain, the tolerance of the system structural parts is reduced, thereby improving the matching accuracy of the system high-speed connector.

[0046] For example, a locking part such as a long screw is designed on the second functional module, and the second functional module is directly locked on the first functional module in terms of the mating relationship. In this way, the number of assembly parts involved in the insertion is relatively small. For example, the assembly parts may include the first functional module, the first connector, the second functional module, and the second connector. The length of the dimension chain can be reduced, so that the gap between the high-speed male and female connectors is smaller after mating, which can meet the high-precision matching requirements of the system.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and do not limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
