[0047] The bus adapter card is an indirect bus interface. Due to the limitations of the server's own mechanical design, it is sometimes difficult to directly connect devices such as network cards and graphics cards to the bus. This difficulty can be overcome through the adapter function of the bus adapter card. Specifically, the bus adapter card can be first inserted into the bus interface, and then the network card, graphics card and other devices can be inserted into the bus adapter card. In order to ensure the stability of the bus adapter card in the chassis, in the prior art, the bus adapter card is generally reinforced by a bracket. Specifically, the bracket is fixed to the chassis by screws, the adapter card is fixed to the bracket by screws, and the adapter card is inserted into the card slot of the bus interface. However, since the above-mentioned adapter card needs to be fixedly connected to the adapter card and the bracket is fixedly connected to the chassis, the installation and removal of the adapter card are relatively complicated.

[0048] In view of this, the present invention provides a bus adapter device, including a bracket, a bus adapter card and a connector, the bracket is connected with the bus adapter card, the bracket includes a first body and at least one elastic first clamping part, the first clamping part is connected to the first body; the connector has a second body and a second clamping part, the second body is provided with a slot, the second clamping part is connected to the side of the second body, the connector is plugged and unplugged with the bus adapter card through the slot; when the bus adapter card is connected to the slot, the first clamping part and the second clamping part are mutually clamped in the plugging and unplugging direction of the bus adapter card to prevent the bus adapter card from being pulled out of the slot. The bus adapter device provided by the present invention connects the bracket with the bus adapter card, clamps the first clamping part on the bracket with the second clamping part on the connector, and inserts the bus adapter card into the slot of the connector at the same time. When the bus adapter card needs to be disassembled, it is only necessary to separate the bracket from the connector, pull out the bus adapter card from the slot at the same time, and then separate the bus adapter card. The operation is simple. Compared with the prior art, the disassembly and assembly process of the bus adapter card is greatly simplified.

Figures 1 to 6The embodiment of the present invention provides a bus adapter device 100, including a bracket 110, a bus adapter card 120 and a connector 130. The bracket 110 is connected to the bus adapter card 120. The bracket 110 includes a first body 111 and at least one elastic first clamping portion 112, and the first clamping portion 112 is connected to the first body 111; the connector 130 has a second body 131 and a second clamping portion 132, and the second body 131 is provided with a slot 1311. The second clamping portion 132 is connected to the side of the second body 131. The connector 130 is plugged and unplugged with the bus adapter card 120 through the slot 1311; when the bus adapter card 120 is connected to the slot 1311, the first clamping portion 112 and the second clamping portion 132 are mutually clamped in the plugging and unplugging direction of the bus adapter card 120 to prevent the bus adapter card 120 from being unplugged from the slot 1311.

[0050] Among them, the connector 130 is generally fixedly connected to the mainboard, and the connector 130 has a slot 1311 for the bus adapter card 120 to be inserted. The bracket 110 is connected to the second clamping portion 132 on the connector 130 through the first clamping portion 112 thereon, so that the position between the bracket 110 and the connector 130 can be relatively fixed. Then, the bus adapter card 120 is inserted into the slot 1311 of the connector 130 on the one hand, and connected to the bracket 110 on the other hand. The bus adapter card 120 is ensured to be stable and reliable through the dual fixation and protection of the connector 130 and the bracket 110. Compared with the prior art of directly fixing the bracket 110 to the chassis with screws, there is no need to worry about the screws falling into the chassis, thereby causing adverse effects, and the design considerations for the accuracy of the bracket 110 and the chassis are omitted, saving production costs.

[0051] The bus adapter device 100 provided in the embodiment of the present invention can connect the bracket 110 with the bus adapter card 120, so that the first clamping portion 112 on the bracket 110 and the second clamping portion 132 on the connector 130 can be clamped together, and the bus adapter card 120 can be inserted into the slot 1311 of the connector 130. When the bus adapter card 120 needs to be disassembled, it is only necessary to separate the bracket 110 from the connector 130, and at the same time, pull the bus adapter card 120 out of the slot 1311, and then separate the bus adapter card 120. The operation is simple, and compared with the prior art, the disassembly and assembly process of the bus adapter card 120 is greatly simplified.

[0052] In the above embodiment, the first clamping portion 112 may be an elastic cantilever, and the first clamping portion 112 has a free end extending toward the connector 130, and the free end has a hook 1121 for clamping with the second clamping portion 132. The free end extends from one side of the first clamping portion 112, mainly to facilitate the connection with the first clamping portion 112. Specifically, a structure similar to the hook 1121 may be designed on the free end. When the bracket 110 is connected to the connector 130, the hook 1121 may be used to hook the second clamping portion 132 on the connector 130. In this way, the bus adapter card 120 inserted into the card slot of the connector 130 may be prevented from loosening. It should be noted that the bus adapter card 120 is generally fixedly connected to the bracket 110. Therefore, when the hook 1121 on the bracket 110 hooks the second clamping portion 132, it is equivalent to limiting the position of the bus adapter card 120 and the slot 1311. As for the bracket 110, on the one hand, the bracket 110 hooks the second clamping portion 132 through the clamping hook 1121, and on the other hand, the bracket 110 indirectly realizes a double connection with the connector 130 through the connection between the bus adapter card 120 and the slot 1311. Therefore, the position of the bracket 110 relative to the connector 130 is also restricted. The bracket 110, the connector 130 and the bus adapter card 120 are tightly matched and connected, which not only simplifies the disassembly and assembly process of the bus adapter card 120, but also improves the compactness of the device and saves space. At the same time, since the bracket 110 does not need to be fixedly connected to the chassis, there is no need to consider the relative position of the connector 130 and the chassis, and it is more applicable.

[0053] like Figure 3 As shown, in the above embodiment, the bracket 110 may further include a support portion 113, and the support portion 113 is connected between the first body 111 and the first clamping portion 112, so that there is a gap between the first clamping portion 112 and the first body 111. The first clamping portion 112 may be movably connected to the support portion 113, and the support portion 113 is mainly used to leave a movable space for the first clamping portion 112 to change the angle with the side of the first body 111.

[0054] In the above embodiment, a pressing portion 1122 may be provided on the side of the first clamping portion 112 away from the free end. When the pressing portion 1122 is subjected to an external force, the angle between the first clamping portion 112 and the side surface of the first body 111 changes, so as to change the relative position of the hook 1121 and the second clamping portion 132. When the bus adapter card 120 is disassembled, the first clamping portion 112 may be changed relative to the side surface of the first body 111 by applying pressure to the pressing portion 1122. At this time, the hook 1121 hooked on the second clamping portion 132 will be disengaged from the second clamping portion 132, so that the bus adapter card 120 can be pulled out of the slot 1311 in the connector 130. The shape of the hook 1121 may be cylindrical, so as to facilitate the disengagement and engagement of the hook 1121 with the second clamping portion 132.

[0055] In the above embodiment, the second clamping portion 132 may be a protrusion protruding from the side wall of the second body 131, and the second clamping portion 132 has a stop step surface that matches and abuts against the hook 1121. When the bracket 110 and the connector 130 are connected, the hook 1121 on the first clamping portion 112 may be hooked on the protruding step surface, which is very easy to operate.

[0056] In the above embodiment, there may be a plurality of second clamping parts 132, which are evenly spaced and arranged on the same side of the second body 131 along the length direction of the slot 1311. Such an arrangement can save materials while satisfying the functional prerequisite of the second clamping part 132.

[0057] In the above embodiment, the bracket 110 further has a buckle 114, and the bus adapter card 120 has a clamping hole 121, and the buckle 114 cooperates with the clamping hole 121 to connect the bus adapter card 120 to the bracket 110. By clamping the buckle 114 on the bracket 110 and the clamping hole 121 on the bus adapter card 120, the bus adapter card 120 can be fixed on the bracket 110, which is easy to operate.

[0058] like Figure 3 As shown, in the above embodiment, the buckle 114 can be an elastic clamping column located on the side of the bracket 110, and the elastic clamping column includes at least two elastic columns arranged opposite to each other, and there is a gap between the elastic columns, and the elastic clamping column is elastically clamped in the clamping hole. Specifically, the diameter of the end of the buckle 114 away from the bracket 110 can be slightly larger than the diameter of the end of the buckle 114 close to the bracket 110. When the buckle 114 and the clamping hole 121 are clamped, the two elastic columns arranged opposite to each other can be pressed in opposite directions to appropriately reduce the spacing between the elastic bodies, so as to facilitate the clamping hole 121 to be sleeved on the buckle 114. After the buckle 114 passes through the clamping hole 121, the pressure applied to the buckle 114 is removed, and under the action of the radial rebound force of the buckle 114, the buckle 114 and the clamping hole 121 are locked.

[0059] like Figure 4 As shown, in the above embodiment, the bracket 110 may further include a stopper 115, the stopper 115 is connected to the first body 111, and the stopper 115 forms a stopper groove on the side of the bus adapter card 120 away from the slot 1311, and the edge of the bus adapter card 120 abuts against the stopper groove. The stopper can protect the end of the bus adapter 100 to prevent the bus adapter 100 from being scratched, and can also further limit and reinforce the bus adapter 100 on the bracket 110 through the stopper 115.

[0060] The bus adapter device 100 provided in the embodiment of the present invention includes a bracket 110, a bus adapter card 120 and a connector 130. The bracket 110 is connected to the bus adapter card 120. The bracket 110 includes a first body 111 and at least one elastic first clamping portion 112, and the first clamping portion 112 is connected to the first body 111; the connector 130 has a second body 131 and a second clamping portion 132, and a slot 1311 is provided on the second body 131. The second clamping portion 132 is connected to the side of the second body 131, and the connector 130 is plugged and unplugged with the bus adapter card 120 through the slot 1311; when the bus adapter card 120 is connected to the slot 1311, the first clamping portion 112 and the second clamping portion 132 are mutually clamped in the plugging and unplugging direction of the bus adapter card 120 to prevent the bus adapter card 120 from being pulled out of the slot 1311. The bus adapter device 100 provided in the embodiment of the present invention connects the bracket 110 with the bus adapter card 120, and snaps the first clamping portion 112 on the bracket 110 with the second clamping portion 132 on the connector 130, and inserts the bus adapter card 120 into the slot 1311 of the connector 130. When the bus adapter card 120 needs to be disassembled, it is only necessary to separate the bracket 110 from the connector 130, and pull the bus adapter card 120 out of the slot 1311, and then separate the bus adapter card 120. The operation is simple, and compared with the prior art, the disassembly and assembly process of the bus adapter card 120 is greatly simplified.

[0061] In addition, the present invention further provides a server, which includes a chassis, a mainboard, and the bus switching device 100 of any one of the above embodiments, wherein the mainboard is disposed in the chassis, and the bus switching device 100 is electrically connected to the mainboard. The bus adapter device 100 includes a bracket 110, a bus adapter card 120 and a connector 130. The bracket 110 is connected to the bus adapter card 120. The bracket 110 includes a first body 111 and at least one elastic first clamping portion 112, and the first clamping portion 112 is connected to the first body 111; the connector 130 has a second body 131 and a second clamping portion 132, and the second body 131 is provided with a slot 1311. The second clamping portion 132 is connected to the side of the second body 131. The connector 130 is pluggable connected to the bus adapter card 120 through the slot 1311; when the bus adapter card 120 is connected to the slot 1311, the first clamping portion 112 and the second clamping portion 132 are mutually clamped in the plugging and unplugging direction of the bus adapter card 120 to prevent the bus adapter card 120 from being pulled out of the slot 1311. By connecting the bracket 110 with the bus adapter card 120, the first clamping portion 112 on the bracket 110 and the second clamping portion 132 on the connector 130 are clamped together, and the bus adapter card 120 is inserted into the slot 1311 of the connector 130. When the bus adapter card 120 needs to be removed, it is only necessary to separate the bracket 110 from the connector 130, and pull the bus adapter card 120 out of the slot 1311, and then separate the bus adapter card 120. The operation is simple, and compared with the prior art, the disassembly and assembly process of the bus adapter card 120 is greatly simplified. Since the bus adapter card 120 in the server provided by this embodiment is more convenient to disassemble and assemble, the server has a higher cost performance and is more competitive in the market.
