Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to an electronic equipment. Background Art

[0002] In communication frame-type equipment, high-speed signals often need to be transmitted across circuit boards. For example, in traditional connection solutions, single-board to single-board transfer needs to be achieved through a backplane. As the transmission rate increases, the impact of cross-circuit board transmission on high-speed signal links becomes increasingly greater. Since the transmission path through the backplane is long, the transmission loss is large, and it is difficult to increase the signal transmission rate. Therefore, a backplane-free orthogonal architecture has emerged. The orthogonal architecture realizes direct connection between single boards, and there is no need to transmit signals through the installation of a backplane, which reduces the transmission loss, thereby increasing the transmission rate of the device and breaking through the line rate bottleneck of the traditional backplane architecture. Single boards in the orthogonal architecture need to be connected with connectors. For example, the connector includes a male connector and a female connector. After the male connector and the female connector are plugged in and matched with each other, the gap between the two will greatly affect the quality of the high-speed signal. However, when reducing the gap between the male connector and the female connector, additional problems will be introduced. For example, in order to pursue zero-gap matching between the male connector and the female connector, mutual collision may occur when installing single boards, resulting in damage to the connector. Summary of the invention

[0003] The present application provides an electronic device, the connector plugging gap of the electronic device is small, thereby improving the signal transmission efficiency of the electronic device.

[0004] The present application provides an electronic device, which includes a chassis, a first single board, a second single board, a connector assembly and a counterpart connector, wherein the connector assembly is mounted on the first single board, and the counterpart connector is mounted on the second single board. The connector assembly is plugged into the counterpart connector. In order to reduce the gap generated after the connector assembly is plugged into the counterpart connector, the connector assembly can be docked with the connector assembly using a movable component to reduce the gap. Specifically, the connector assembly includes a fixed frame, a connector and an elastic member, and the fixed frame includes a bottom wall and a side wall, and the bottom wall and the side wall are connected to form a receiving cavity. The side wall may be cylindrical and form a sleeve after being connected to the bottom wall. The hollow part of the sleeve is the receiving cavity. The connector is mounted in the receiving cavity and can slide in the receiving cavity along the plugging direction. The counterpart connector is mounted on the second single board. Due to the tolerance generated during the production process, the tolerance may be generated by the second single board or generated when the counterpart connector is equipped with the second single board. Under the influence of the tolerance, the connector may not be plugged tightly with the counterpart connector. An elastic member is arranged in the accommodating cavity so that the elastic member is located between the bottom wall and the connector. The elastic member can drive the connector to abut against the opposite connector so that the connector and the opposite connector can be plugged in tightly, thus overcoming the problem of gap after plugging caused by the above tolerance.

[0005] The above-mentioned connector is a female connector or a male connector, which can be selected and designed according to needs.

[0006] The first single board and the second single board are installed in the chassis, and the first single board includes a first body and a first stop block, and the first stop block is arranged on the first body. The chassis includes a first limit structure, and the first limit structure is used to limit the first single board. The first limit structure is located on the side of the first stop block facing the second single board, and the first limit structure and the first stop block are counteracted, so that there is a preset distance between the first single board and the second single board, which reduces the situation that the fixed frame collides with the opposite end connector or the first single board collides with the second single board due to the first single board being inserted too deep into the chassis. Under the premise of ensuring that the preset distance is maintained between the first single board and the second single board, the movable connector slides along the plugging direction under the elastic force of the elastic member according to the actual distance between the first single board and the second single board and plugs with the opposite end connector, so as to realize the signal transmission of the first single board and the second single board. The electronic device of the present application can not only reduce the situation that the first single board and the second single board collide with each other, but also make the matching clearance between the connector assembly and the opposite end connector smaller, so that the signal transmission efficiency of the electronic device is higher.

[0007] The first single board and the second single board can be installed in an orthogonal manner, that is, the first single board and the second single board are installed perpendicular to each other, for example, the first single board is installed vertically in the chassis, and the second single board is installed horizontally in the chassis. The electronic device of the present application adopts an orthogonal architecture, which minimizes the wiring distance from the first single board to the second single board and improves the signal transmission rate.

[0008] In order to reduce the situation where the connector protrudes too far from the fixed frame and causes the connector to fall off. The fixed frame may also include a limiter, and the connector is provided with a shoulder, which is located between the limiter and the bottom wall. When the elastic member drives the connector to slide along the plug-in direction, the limiter abuts against the shoulder to limit the sliding range of the connector. At the same time, when the elastic member applies an elastic force toward the opposite connector to the connector, the setting of the limiter gives the elastic member a pre-tightening force. When the connector is plugged into the opposite connector, the elastic member drives the connector to abut against the opposite connector, and the pre-tightening force reduces the gap between the connector and the opposite connector in the plug-in direction, thereby improving the connection effect between the connector and the opposite connector.

[0009] In a further technical solution, after the first single board and the second single board are installed in the chassis, the connector assembly and the opposite connector may not be in a facing position along the plugging direction, which may cause the connector to fail to plug into the opposite connector. Therefore, a gap is provided between the connector and the side wall of the fixing frame, so that the elastic member can drive the connector to float in the accommodating cavity, and the floating direction is perpendicular to the plugging direction, which is conducive to improving the connection effect between the connector assembly and the opposite connector.

[0010] When the above-mentioned gap is specifically set, the width of the gap is less than or equal to 0.5 mm.

[0011] The first single board includes a first circuit board, and the connector is connected to the first circuit board through a cable to achieve signal transmission between the first single board and the second single board. The cable can be a flexible cable, so that the connector has little effect on the connection reliability between the connector and the first circuit board when moving, which is conducive to improving the service life of the electronic device.

[0012] The bottom wall has a through hole, and the cable passes through the through hole to connect with the connector.

[0013] In a further technical solution, in order to balance the force on the connector, the connector assembly may include at least two elastic members, and the at least two elastic members are symmetrically arranged between the connector and the bottom wall.

[0014] The electronic device includes at least one first single board and at least one second single board, at least one second single board is arranged along the first direction, and at least one first single board is arranged along the second direction. The first direction, the second direction and the plug-in direction are perpendicular to each other. Each first single board is to be plugged with each second single board. In order to make the structure of the electronic device compact, the fixed frame may include at least two accommodating cavities, at least two accommodating cavities are arranged along the first direction, each accommodating cavity is provided with a connector, and each connector is used to connect with the opposite end connector.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as being limited to the embodiments described herein. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted. The words expressing position and direction described in the embodiments of the present application are all illustrated by taking the accompanying drawings as examples, but changes may be made as needed, and the changes made are all included in the scope of protection of the present application. The drawings of the embodiments of the present application are only used to illustrate the relative position relationship, and they do not represent the true proportion.

[0024] It should be noted that specific details are described in the following description to facilitate understanding of the present application. However, the present application can be implemented in a variety of other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present application. Therefore, the present application is not limited to the specific implementation methods disclosed below.

[0025] In order to facilitate the understanding of the electronic device provided by the embodiment of the present application, its application scenario is first introduced below. The electronic device in the embodiment of the present application can be an electronic device such as a communication device (such as a router), a computing device (such as a cluster server), a network device (such as a switch) or a storage device (such as a storage array). The present application does not limit the specific type of electronic device, as long as the electronic device that needs to be connected using a connector can adopt the technical solution provided by the present application.

[0026] The technical solution of the present application is particularly suitable for single-board interoperability scenarios in orthogonal architectures. Orthogonal architecture, whose full name is backplane-free orthogonal architecture, refers to a hardware structure in which, for example, the line processing unit (LPU) of a router or the interface board (Interface Board) of a switch and the switch fabric unit (SFU) are orthogonal, and the two are directly connected. The mathematical meaning of "orthogonal" is the vertical relationship between vectors in three-dimensional space. Corresponding to the hardware architecture, the line board is inserted horizontally and the switch fabric board is inserted vertically, or the line board is inserted vertically and the switch fabric board is inserted horizontally.

[0027] Figure 1 is a schematic diagram of the structure of an electronic device in an embodiment of the present application, such as Figure 1 As shown, an electronic device provided by the present application includes a chassis 100, a first single board 10, a second single board 20, a connector assembly 1 and a counterpart connector 2. The first single board 10 and the second single board 20 are assembled in an orthogonal manner, and specifically, the first single board 10 and the second single board 20 can be perpendicular to each other. In a specific embodiment, the first single board 10 can specifically be the above-mentioned switching network board, and the second single board 20 can specifically be the above-mentioned circuit board. Specifically, the above-mentioned chassis 100 can be a square box or a square frame. Figure 1 The embodiment shown takes the chassis 100 as a square box as an example. Figure 1 As shown, the chassis 100 includes a top plate 101, a side plate 102 and a bottom plate 103 that are interconnected, wherein the top plate 101 and the bottom plate 103 are parallel to each other. In this embodiment, the second single board 20 is horizontally mounted on the chassis 100, parallel to the top plate 101. The first single board 10 is longitudinally mounted on the chassis 100, perpendicular to both the bottom plate 103 and the side plate 102. The connector assembly 1 is mounted on the first single board 10, and the opposite connector is mounted on the second single board 20. The connector assembly 1 is plugged into the opposite connector 2 to realize signal transmission between the first single board 10 and the second single board 20. The electronic device of the present application adopts an orthogonal architecture, which minimizes the wiring distance from the first single board 10 to the second single board 20 and improves the signal transmission rate.

[0028] Please continue to refer to Figure 1When the first single board 10 and the second single board 20 are assembled, if the distance reserved between the first single board 10 and the second single board 20 is not enough, it may cause the first single board 10 and the second single board 20, or the connector assembly 1 and the opposite connector 2 to collide with each other. In order to solve the above problem, in the embodiment provided by the present application, the first single board 10 also includes a first body 11 and a first stop block 13. The chassis 100 includes a first limiting structure 104, and the first limiting structure 104 is located on the side of the first stop block 13 facing the second single board 20. The first limiting structure 104 is used to limit the first single board 10. During assembly, the second single board 20 is first installed on the chassis 100, and then the first single board 10 is inserted into the chassis 100, so that the first stop block 13 and the first limiting structure 104 are abutted against each other, so that the second single board 20 and the first single board 10 are spaced a preset distance apart along the plug-in direction Z. This can reduce the possibility that the first board 10 is inserted too deeply into the chassis 100 during installation, causing the connector assembly 1 to collide with the opposite connector 2 and be damaged.

[0029] The positional relationship between the first stop block 13 and the first limiting structure 104 is described below with examples.

[0030] In one embodiment, if Figure 1 As shown, the first limiting structure 104 can be a convex block, and the first limiting structure 104 can be arranged on the side of the top plate 101 of the chassis 100 facing the inside of the chassis 100, and the first stop block 13 can be arranged on the side of the first body 11 facing the top plate 101. The first limiting structure 104 can be specifically located in the middle of the top plate 101 along the plugging direction Z, and the first stop block 13 is located at the edge of the first body 11 facing the top plate 101.

[0031] Figure 2 This is a stereogram of the assembly of the second single board and the first single board in one embodiment of the present application. Figure 3 FIG. 1 is a schematic diagram of the structure of an electronic device in another embodiment of the present application. Figure 2 and Figure 3 In another embodiment, the first stop block 13 may be strip-shaped and installed on the side of the first body 11 away from the second single board 20. The length of the first stop block 13 along the first direction X is greater than the length of the first body 11. The first direction X is perpendicular to the top plate 101. The end of the first stop block 13 facing the top plate 101 and the end facing the bottom plate 103 are partially protruded relative to the first body 11. The first limiting structure 104 may be two, which are respectively arranged at the ends of the top plate 101 and the bottom plate 103 away from the side plate 102. In a possible implementation, the side plate 102 is perpendicular to the plug-in direction Z. When installing the first single board 10, the upper and lower ends of the first stop block 13 can both be against the first limiting structure 104 to limit the first single board 10.

[0032] like Figure 1 or Figure 3 As shown, the second board 20 may include a second body 21 and a second stopper 23. The second stopper 23 is located on the side of the second body 21 facing the side plate 102, and the second stopper 23 abuts against the side plate 102 to reduce the collision between the second board 20 and the chassis 100.

[0033] In an optional embodiment, the first stop block 13 and the second stop block 23 may be made of a flexible material, such as rubber, or a flexible film material may be coated on the surface of the first stop block 13 and the second stop block 23. In this solution, the first stop block 13 can play a buffering role when it abuts against the first limiting structure 104, and similarly, the second stop block 23 can play a buffering role when it abuts against the side plate 102. Therefore, the chassis structure can be protected and vibration and noise can be reduced.

[0034] like Figure 2 As shown, in one embodiment, the electronic device includes at least one first single board 10 and at least one second single board 20. At least one second single board 20 is arranged along a first direction X, and at least one first single board 10 is arranged along a second direction Y. The first direction X, the second direction Y, and the plugging direction Z are perpendicular to each other.

[0035] Figure 4 FIG. 1 is a schematic diagram of assembling the second single board and the first single board in one embodiment of the present application, as shown in FIG. Figure 4 As shown, when preparing the second single board 20, due to the influence of the manufacturing process, structural tolerances will appear between different second single boards 20. Or under the influence of environmental factors, the second single board 20 will be deformed, so that the length of each second single board 20 along the plug-in direction Z is inconsistent. When installing the opposite connector 2, installation tolerances will also occur, resulting in different distances between each opposite connector 2 installed on the second single board 20 and the corresponding connector assembly 1 installed on the first single board 10 along the plug-in direction Z. The total tolerance of different second single boards 20 caused by structural tolerance, deformation and opposite connector installation tolerance is δ1.

[0036] Figure 5 Schematic diagram of the structure of the connector assembly in one embodiment of the present application. Under the influence of the above-mentioned total tolerance, the connector assembly 1 and the opposite connector 2 may not be connected or plugged into place. To this end, the connector assembly 1 of the electronic device of the present application uses a movable connector to plug into the opposite connector 2. Specifically, in combination Figure 4 and Figure 5, the connector assembly 1 includes a fixed frame 3, a connector 4 and an elastic member 5. The fixed frame 3 includes a bottom wall 31 and a side wall 32, the bottom wall 31 and the side wall 32 are connected to form a housing chamber 30, and the connector 4 is installed in the housing chamber 30. In a possible implementation, the bottom wall 31 is perpendicular to the plug-in direction Z, the side wall 32 is parallel to the plug-in direction Z, and the bottom wall 31 and the side wall 32 are enclosed to form a sleeve-like fixed frame 3. The connector 4 is installed in the fixed frame 3 and can slide along the plug-in direction Z. The elastic member 5 is arranged between the connector 4 and the bottom wall 31, and the elastic member 5 is used to apply an elastic force to the connector 4 toward the opposite connector 2, driving the connector 4 to abut against the opposite connector 2. The connector 4 can slide along the plug-in direction Z, which reduces the situation that the opposite connector 2 cannot be connected or plugged into the connector assembly 1 of the first single board 10 due to the total tolerance δ1 of the second single board 20.

[0037] Please continue to refer to Figure 4 In one embodiment, along the first direction X, a plurality of second boards 20 are aligned with the second stop block 23 at the left end as the limit point, and along the second direction Y, a plurality of first boards 10 are aligned with the first stop block 13 at the right end as the limit point, so that the positions of the first board 10 and the second board 20 in the chassis 100 are determined, thereby ensuring that the first board 10 and the second board maintain a preset distance and do not collide with each other. Under the premise of ensuring that the first board 10 and the second board 20 maintain a preset distance, the movable connector 4 slides along the plugging direction Z according to the actual distance between the first board 10 and the second board 20 under the elastic force of the elastic member 5 and plugs with the opposite connector 2 without gap, so as to realize the signal transmission between the first board 10 and the second board 20. The electronic device of the present application can not only reduce the collision between the first board 10 and the second board 20, but also make the matching gap between the connector assembly 1 and the opposite connector 2 smaller, so that the signal transmission efficiency of the electronic device is higher.

[0038] In an optional embodiment, the above-mentioned connector 4 can be a female connector or a male connector, and the present application does not impose any restrictions on this, and it can be selected and designed according to the connection requirements.

[0039] In a specific embodiment, the elastic member 5 can be a spring, one end of which is connected to the connector 4, and the other end of which is connected to the bottom wall 31. Specifically, the spring is crimped between the connector 4 and the bottom wall 31.

[0040] Figure 6 FIG. 1 is an assembly diagram of a connector assembly and a counterpart connector in one embodiment of the present application, such as Figure 6As shown, in order to reduce the situation where the connector 4 extends too long outside the fixed frame 3. The fixed frame 3 may also include a stopper 33, which is arranged on the side wall 32, and the connector 4 is provided with a stop shoulder 41. When the elastic member 5 applies elastic force to the connector 4 and the connector 4 is located at a preset position, the stopper 33 abuts against the stop shoulder 41. The stopper 33 limits the sliding range of the connector 4, ensuring that the connector 4 is limited in the accommodating cavity 30 and does not slide out.

[0041] When the above connector assembly 1 is specifically set, in the natural state, the elastic member 5 is in an energy storage state, and applies an elastic force to the connector 4 toward the opposite connector 2. The setting of the limit member 33 enables the elastic member 5 to have a pre-tightening force. The connector 4 can be plugged into the opposite connector 2 under the action of the pre-tightening force. The above natural state refers to the state when the connector 4 is not plugged into the opposite connector 2. In a specific embodiment, during the plugging process, the connector 4 also needs to overcome the friction resistance from the opposite connector 2. Therefore, the pre-tightening force of the elastic member 5 should be greater than or equal to the friction force of the plug-in fit between the connector 4 and the opposite connector 2 multiplied by the safety factor, which is conducive to improving the effect of gapless plug-in between the connector 4 and the opposite connector 2. The above safety factor refers to the coefficient used to reflect the safety degree of the structure in the engineering structure design method. The determination of the safety factor needs to take into account various uncertainties such as load, mechanical properties of materials, differences between test values ​​and design values ​​and actual values, calculation mode and construction quality.

[0042] Please continue to refer to Figure 4 , because the first single board 10 is also affected by the manufacturing process and the environment, tolerances will occur. When installing the connector assembly 1, the length of each connector assembly 1 along the plug-in direction Z is inconsistent, resulting in different distances between each connector assembly 1 installed on the first single board 10 and the corresponding opposite connector 2 installed on the second single board 20 along the plug-in direction Z. The total tolerance of the first single board 10 caused by structural tolerance, deformation and installation tolerance of the connector assembly 1 is δ2. Figure 4 As shown, the states of each connector 4 from top to bottom are: the connector 4 is in the maximum limit position in the fixed frame 3; the connector 4 is located in the middle position of the fixed frame 3 after being plugged into the opposite connector 2; the connector 4 is pressed by the opposite connector 2 to be in the minimum limit position in the fixed frame 3. The maximum distance that the connector 4 can move in the accommodating cavity 30 is D. In the embodiment of the present application, the maximum movement amount D of the connector 4 in the fixed frame 3 is ≥ δ1+δ2, so that the first single board 10 and the second single board 20 are connected in the state of the maximum total tolerance, and the movement amount of the connector 4 of the connector assembly 1 in the plug-in direction Z can absorb all tolerances, so that the connector 4 and the opposite connector 2 can be plugged in without gaps, and the signal can be transmitted at high speed and reliably through the above-mentioned connector assembly 1 and the opposite connector 2.

[0043] Combination Figure 4 and Figure 6 , when assembling the second single board 20 along the first direction X, there will also be installation tolerances, for example, the distances between two adjacent second single boards 20 are not equal, or the projections of two adjacent second single boards 20 along the first direction X do not overlap, or the projections of the opposite connectors 2 installed on two adjacent second single boards 20 along the first direction X do not overlap. As a result, the positions of the opposite connector 2 and the connector assembly 1 along the plug-in direction Z cannot be completely aligned. To overcome this problem, a gap can be provided between the connector 4 and the side wall 32, and there is also a gap between the connector 4 and the limiter 33 along the first direction X and the second direction Y, so that the connector 4 can float in the fixed frame 3, that is, in addition to being able to slide along the plug-in direction Z, the connector 4 can also move along the first direction X and the second direction Y.

[0044] In a specific embodiment, the width of the gap can be less than or equal to 0.5 mm. The gap between the accommodating cavity 30 and the connector 4 is matched, and the elastic member 5 drives the connector 4 to slide along the plug-in direction Z, so that the connector 4 can float in three directions in the accommodating cavity 30, thereby reducing the problem that the connector 4 cannot be plugged in or cannot be plugged in properly with the opposite connector 2 due to various tolerances during the assembly process of the first single board 10 and the second single board 20.

[0045] Please continue to refer to Figure 4 In one embodiment, the first single board 10 includes a first body 11 and a first circuit board 12, and the first circuit board 12 is fixedly connected to the first body 11. The connector 4 is connected to the first circuit board 12 via a cable 6. Please refer to Figure 6 The bottom wall 31 of the fixing frame 3 faces the first circuit board 12, and a through hole 311 may be provided on the bottom wall 31 for the cable 6 to pass through. The cable 6 may be a flexible cable that is deformed as the connector 4 moves, so that the connector 4 has little effect on the connection reliability between the connector 4 and the first circuit board 12 when moving, which is beneficial to improving the service life of the electronic device.

[0046] The above-mentioned second single board 20 includes a second body 21 and a second circuit board 22, the second circuit board 22 is fixedly installed on the second body 21, and the opposite connector 2 is connected to the second circuit board 22. The opposite connector is plugged into the connector assembly to realize the connection between the first single board and the second single board. The electronic device of the present application adopts a plug-in method with one end fixed and the other end floating to realize the signal transmission between the first single board 10 and the second single board 20. The above-mentioned one-end fixed refers to that the opposite connector 2 is fixed relative to the second single board 20, and the one-end floating refers to that the connector 4 is not fixed relative to the first single board 10. The floating design of the connector 4 can adapt to the situation where the assembly position of the single board does not match due to the structure and installation tolerance, so that the matching clearance between the connector 4 and the opposite connector is smaller, thereby making the signal transmission efficiency of the electronic device higher.

[0047] In order to balance the force on the connector 4, the connector assembly 1 may include at least two elastic members 5, which are symmetrically arranged between the connector 4 and the bottom wall 31. In a specific implementation, the through hole 311 may be located at the center of the bottom wall 31, and the central axis of the connector 4 may be axially arranged with the through hole 311. The elastic members 5 are evenly distributed around the through hole 311.

[0048] Please continue to refer to Figure 2 In one embodiment, a plurality of second single boards 20 are arranged along a first direction X, and a plurality of first single boards 10 are arranged along a second direction Y. Each second single board 20 is provided with a plurality of opposite connectors 2, and the plurality of opposite connectors 2 are arranged along the second direction Y. Each first single board 10 must be plugged with a plurality of second single boards 20. In order to simplify the equipment structure and improve assembly efficiency. When the above-mentioned fixed frame 3 is specifically prepared, at least two accommodating cavities 30 can be opened on the fixed frame 3, and the above-mentioned at least two accommodating cavities 30 are arranged along the first direction X, and a connector 4 is provided in each accommodating cavity 30. Each connector 4 is plugged with the corresponding opposite connector 2. In other words, by installing a fixed frame 3 on each first single board 10, a first single board 10 can be plugged with the opposite connectors 2 of a plurality of second single boards 20 to realize signal transmission, thereby improving assembly efficiency.
