The present invention belongs to the field of electronic assembly technologies, and in particular, relates to a pluggable apparatus of a circuit board, and a server.
A Peripheral Component Interconnect Express (PCI-E) card is used for interconnection of peripheral components of a computer or a communications platform and is commonly applied to a product such as a server. The PCI-E card can further support hot plugging to improve maintainability of a device and meet an assembly requirement.
A connector (also referred to as a golden finger) of the PCI-E card and an installation panel are respectively located on two adjacent sides of the PCI-E card, and therefore interface directions of the connector and the installation panel are perpendicular to each other. At present, to insert a connector of a PCI-E card into a slot of a chassis, a chassis cover needs to be opened first, the PCI-E card is placed in the interior of the chassis, and then the connector of the PCI-E card is inserted into the slot. On the contrary, the chassis cover also needs to be opened first to pull the connector of the PCI-E card out of the slot.
Because interface directions of a connector of a PCI-E card and an installation panel are perpendicular to each other, and therefore plugging of the connector can be implemented only after a chassis cover is opened first, and hot plugging of the PCI-E card without opening the chassis cover is difficult to implement.
Embodiments of the present invention provide a pluggable apparatus of a circuit board and a server disposed with the pluggable apparatus of the circuit board, so as to implement hot plugging of a PCI-E card.
In order to achieve the foregoing objective, the embodiments of the present invention adopt the following technical solutions:
A pluggable apparatus of a circuit board includes a base plate, a pulling strip, a rotating member, and a carrier plate, where the pulling strip is movably connected to the base plate by using a transverse guide mechanism, sawteeth are formed on a body of the pulling strip, and the pulling strip further includes a handle that extends out of the base plate, where the handle is used as a holding part for moving the pulling strip; the rotating member is in a bending line shape, and the rotating member includes a first arm, a first rotating shaft, and a second arm, where the first rotating shaft is disposed at a turning of the rotating member, and the first rotating shaft is configured to movably connect the rotating member and the base plate; the first arm and the second arm are connected by using the first rotating shaft, where sawteeth are formed on a tail end of the first arm and are engaged with the sawteeth on the pulling strip, and the second arm is movably connected to the carrier plate by using a transmission mechanism; the carrier plate is movably connected to the base plate by using a longitudinal guide mechanism; and a clamping trough is provided on the carrier plate and is configured to fasten the circuit board.
A server is provided, where the interior of a chassis of the server includes a slot, a circuit board (such as a PCI-E card), and the foregoing pluggable apparatus of the circuit board; the circuit board is fastened on the pluggable apparatus, and the pluggable apparatus is configured to insert a connector of the circuit board into the slot or pull the connector of the circuit board out of the slot.
Compared with the prior art, the technical solutions provided in the present invention have the following advantages: a pulling strip can transversely move relative to a base plate by using a transverse guide mechanism and drive, by using engaged sawteeth, a rotating member to rotate around a first rotating shaft. Because the rotating member is in a bending line shape, under the driving of the pulling strip, at the same time when a first arm transversely swings, a second arm longitudinally swings, and the second arm drives, by using a transmission mechanism, a carrier plate to move. Under the co-action of a longitudinal guide mechanism and the transmission mechanism, the carrier plate longitudinally moves relative to the base plate.
A PCI-E card is first fastened on the carrier plate through a clamping trough to make the PCI-E card and a pluggable apparatus form an entirety. When the PCI-E card is located inside a chassis of a device, in a case that the device is powered on, the carrier plate can drive, by transversely moving the pulling strip, the PCI-E card to longitudinally move, so that a connector of the PCI-E card is inserted into or pulled out of a slot inside the device, thereby implementing hot plugging of the PCI-E card.
To illustrate the technical solutions in the embodiments of the present invention more clearly, the following briefly introduces the accompanying drawings for describing the embodiments. The accompanying drawings in the following description show merely some embodiments of the present invention, and a person of ordinary skill in the art may still derive other drawings from the accompanying drawings without creative efforts.
The following clearly describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. The described embodiments are merely a part rather than all of the embodiments of the present invention. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
As shown in
The pulling strip 2 is movably connected to the base plate 1 by using a transverse guide mechanism, and sawteeth are formed on a body of the pulling strip 2. One end of the pulling strip 2 extends out of a plate surface of the base plate 1 and forms a handle 20 that is used as a holding part for moving the pulling strip 2. The rotating member 3 is in a bending line shape, and preferably, a bending angle is 90°. The rotating member 3 includes a first arm, a first rotating shaft (or a hinge) 11, and a second arm; the first rotating shaft 11 is disposed at a turning of the rotating member 3, and the first rotating shaft 11 is configured to movably connect the rotating member 3 and the base plate 1. The first arm and the second arm of the rotating member 3 are connected by using the first rotating shaft 11, sawteeth are formed on a tail end of the first arm and are engaged with the sawteeth on the pulling strip 2, and the second arm is movably connected to the carrier plate 4 by using a transmission mechanism. The carrier plate 4 is movably connected to the base plate 1 by using a longitudinal guide mechanism, and multiple clamping troughs 43 are provided on the carrier plate 4 to fasten the circuit board (such as a PCI-E card).
The transmission mechanism includes a transmission guide trough 31 provided on the second arm of the rotating member 3, and a first fixing pin 41 sheathed in the transmission guide trough 31, where the first fixing pin 41 is connected to the carrier plate 4 in a fixed manner.
A specific implementation manner of the transverse guide mechanism includes a plurality of groups of transverse guide troughs 21 provided on the pulling strip 2, and a second fixing pin 12 fastened on the base plate 1; and the second fixing pin 12 is sheathed in the transverse guide trough 21, so that the pulling strip 2 can transversely move relative to the base plate 1.
In the same way, a specific implementation manner of the longitudinal guide mechanism includes a plurality of groups of longitudinal guide troughs 42 provided on the carrier plate 4, and a third fixing pin 13 fastened on the base plate 1; and the third fixing pin 13 is sheathed in the longitudinal guide trough 42, so that the carrier plate 4 can longitudinally move relative to the base plate 1.
The pulling strip 2 can transversely move relative to the base plate 1 by using the transverse guide mechanism and drive, by using the engaged sawteeth, the rotating member 3 to rotate around the first rotating shaft 11. Because the rotating member 3 is in a bending line shape, under the driving of the pulling strip 2, at the same time when the first arm transversely swings, the second arm longitudinally swings, and the transmission guide trough 31 provided on the second arm drives the first fixing pin 41 and the carrier plate 4 to move; and by cooperating with the longitudinal guide mechanism, the first fixing pin 41 further slides along the transmission guide trough 31 relative to the rotating member 3 while longitudinally moving, thereby implementing longitudinal moving of the carrier plate 4 relative to the base plate 1.
A PCI-E card 5 is first fastened on the carrier plate 4 through the clamping trough 43 to make the PCI-E card 5 and the pluggable apparatus form an entirety. As shown in
Further, as shown in
When the pulling strip 2 is in a pull-out position, an elastic force of the spring 7 enables the rotating rod 6 to rotate around the second rotating shaft (or a hinge) 61 to a locking position, the hook 62 clamps the locking end 26 on the pulling strip 2, and meanwhile a second end of the rotating rod 6 extends out of the plate surface of the base plate 1. The pulling strip 2 is locked by using the hook 62, and the carrier plate (not shown in the figure) and the PCI-E card (not shown in the figure) fastened on the carrier plate are also locked, so as to prevent the carrier plate and the PCI-E card from longitudinally sliding randomly. Especially in a process of transversely inserting the entirety formed by the pluggable apparatus and the PCI-E card into the chassis, locking the PCI-E card can prevent the connector of the PCI-E card from colliding with the slot or another part inside the chassis, thereby avoiding a possibility of damaging the connector.
When the entirety formed by the pluggable apparatus and the PCI-E card is to be transversely inserted to the bottom, a subrack of the chassis contacts with and pushes the second end of the rotating rod 6 to enable the rotating rod 6 to balance the elastic force of the spring 7 and rotate around the second rotating shaft 61. When the pluggable apparatus is transversely inserted to the bottom, the rotating rod 6 is enabled to exactly rotate to an unlocking position; and in this case, the second end of the rotating rod 6 is pushed inside the plate surface of the base plate, and the hook 62 is detached from the locking end 26 on the pulling strip 2. In this way, the pulling strip 2 can be freely pulled out or pushed into to enable the connector of the PCI-E card 5 to be inserted into or pulled out of the slot inside the device.
It should be noted that, positions of the transverse guide trough and the second fixing pin in the transverse guide mechanism can be interchanged, that is, the transverse guide trough is provided on the base plate and the second fixing pin is fastened on the pulling strip. In the same way, positions of the longitudinal guide trough and the third fixing pin in the longitudinal guide mechanism can also be interchanged.
In addition, the pluggable apparatus of the circuit board provided in the embodiment of the present invention is not only applicable to plugging of the PCI-E card, but also applicable to a circuit board plugging scenario in another form.
This embodiment is substantially the same as Embodiment 1. A difference is that: as shown in
When the rotating member 3 rotates, with cooperation between the first fixing pin 312 and the longitudinal guide mechanism, the carrier plate 4 is driven to longitudinally move, and meanwhile, the first fixing pin 312 further transversely slides along the transmission guide trough 412 relative to the carrier plate 4.
It should be noted that, implementation manners of the transmission mechanism between the second arm of the rotating member and the carrier plate are not limited to the two kinds in Embodiment 1 and Embodiment 2. For example, the implementation manner of the transmission mechanism may further be similar to an implementation manner in which sawteeth between the pulling strip and the first arm of the rotating member are engaged, or the like.
This embodiment is substantially the same as Embodiment 2. A difference is that: as shown in
The pulling strip 2 drives the two rotating members 3 to simultaneously rotate, and the two rotating members 3 simultaneously drive the carrier plate (not shown in the figure) to longitudinally move. That is, the carrier plate has two force bearing points, so that stress of the carrier plate is more balanced and a moving process is more stable. In addition, if one of the rotating members is damaged, the other rotating member can also independently drive the carrier plate to longitudinally move.
This embodiment is substantially the same as Embodiment 3, and there are also two rotating members. A difference is that: as shown in
In this embodiment, the reversing gear 8 is disposed between the rotating member 3b and the pulling strip 2, that is, the rotating member 3b is indirectly engaged with the pulling strip 2 by using the reversing gear 8, so that rotation directions of the two rotating members, that is, 3a and 3b, may be opposite, and transverse acting force of the two rotating members, that is, 3a and 3b, acting on the carrier plate (not shown in the figure) can be mutually counteractive, thereby further improving stability in a moving process of the carrier plate.
As shown in
The pluggable apparatus of the circuit board provided in this embodiment of the present invention has the same technical feature as the pluggable apparatus of the circuit board provided in the foregoing embodiments of the present invention, so that the same technical effect can be created and the same technical problem can be solved.
The foregoing descriptions are merely specific implementation manners of the present invention, but are not intended to limit the protection scope of the present invention. Any variation or replacement readily figured out by a person skilled in the art within the technical scope of the present invention shall all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
