Detailed Description
The inventor finds that, compared with PCI, PCI-X and AGP interfaces, the PCI-E interface adopts high-speed serial point-to-point dual-channel high-bandwidth transmission, and connected devices allocate independent channel bandwidth and do not share bus bandwidth, so that the PCI-E interface is widely applied to a mainboard. Generally, a plurality of PCI-E slots are installed on a motherboard for inserting expansion cards to improve the performance of a server on which the motherboard is located.
However, due to the limitation of the space of the motherboard, the distance between the PCI-E slots is relatively narrow, so that the space reserved for plugging and unplugging the expansion card for the user is very small, when the expansion card is plugged into the adjacent PCI-E slot, it is difficult to plug and unplug the expansion card into the middle PCI-E slot, and in such a situation that the operation is inconvenient, the user needs to expend a great force to plug and unplug the expansion card, and if the force is too great, the expansion card or the PCI-E slot is likely to be damaged, even the motherboard may be damaged, and a great loss is likely to be caused.
Based on this, in the embodiment of the application, from the perspective of convenience for plugging and unplugging the expansion card by a user, a redesigned expansion slot and an auxiliary device for plugging and unplugging the expansion card are provided, so that the difficulty of plugging and unplugging the expansion card is greatly reduced, a user can conveniently, quickly and accurately plug and unplug the expansion card from the expansion slot, further, any damage to the mainboard and the expansion card cannot be caused, the service lives of the expansion card and the mainboard are prolonged, and the reliability and the safety of the mainboard and the expansion card of a computer can be ensured on the basis of providing convenience for the user.

The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.
Referring to fig. 1, a schematic structural diagram of an expansion card plugging system provided in an embodiment of the present application is shown.
The expansion card plugging system 10 comprises a system including an expansion slot 100 and an expansion card plugging auxiliary device 200;
the expansion card insertion and extraction assisting device 200 is used for clamping an expansion card 20, inserting the expansion card into the expansion slot 100 and extracting the expansion card 20 inserted into the expansion slot 100;
the expansion slot 100 is used for matching with the expansion card plugging auxiliary device 200 to facilitate the plugging and unplugging of the expansion card 20.
As shown in fig. 1, a plurality of expansion slots 100 are mounted on the main board 30. Fig. 2 is a cross-sectional view of the expansion card plugging system 10.
Fig. 3 is a cross-sectional view of the slot 100 provided in the embodiment of the present application, and the slot 100 will be described in detail with reference to fig. 3.
A pair of first sliding grooves 110 are drilled at both ends of the expansion slot 100, a second sliding groove 120 is drilled between the pair of first sliding grooves 110, a fixed pulley groove 130 is drilled between the second sliding groove 120 and the adjacent first sliding groove 110, and the first sliding groove 110 and the second sliding groove 120 are communicated through the fixed pulley groove 130.
Each first sliding chute 110 is connected with a first sliding block 111 in a sliding manner, each second sliding chute 120 is connected with a second sliding block 121 in a sliding manner, and a micro fixed pulley 131 is fixedly connected in the fixed pulley chute 130; an elastic rope 140 is connected between the lower end of the second sliding block 121 and the bottom of the inner wall of the second sliding chute 120, and the upper end of the second sliding block 121 is fixedly connected with a jacking block 150; the lower end of the first slider 111 and the lower end of the second slider 121 are connected by an inelastic thread 160 that passes over the micro fixed pulley 131.
It can be understood that, by inserting the insertion block 210 of the expansion card insertion and extraction assisting device 200 into the first sliding slot 110, the expansion card 20 held by the expansion card insertion and extraction assisting device 200 is aligned with the expansion slot 10; a height change of the second slider 121 is pulled by the inelastic thread 160 passing over the micro fixed pulley 131 by a height change of the first slider 111; the height change of the second slider 121 causes the height change of the jacking block 150 to generate a power for plugging and unplugging the expansion card 20, so as to conveniently realize the plugging and unplugging of the expansion card 20.
It will be appreciated that the inelastic threads 160 may be PE fiber type threads. The non-elastic fine wire 160 can be made into a super-smooth wire body by adopting super-strong PE fiber as a raw material and applying a wire body reinforcing process, a lubricating factor can be added on the surface of the wire body, and the smooth coating enables the non-elastic fine wire 160 to be durable in use, durable in color, not easy to wear and fade, and has very large strength and diameter ratio and the probability of entanglement reduction.
In order that the expansion slot 100 itself may also achieve the alignment of the expansion card 20, as shown in fig. 4, the expansion slot 100 may further include: the middle column is provided with a third sliding groove 180 in a chiseled mode; a limiting expansion plate 181 is slidably connected in the third sliding groove 180, and a compression spring 190 is connected between one end of the limiting expansion plate 181 and the bottom of the inner wall of the third sliding groove 180.
In a specific implementation, the height of the limiting expansion plate 181 can be changed by changing the elastic state of the compression spring 190, so as to align the expansion card 20 held by the auxiliary device 200 and the expansion slot 100, and the alignment between the expansion card 20 held by the auxiliary device 200 and the expansion slot 100 can be completed without inserting the insertion block 210 of the auxiliary device 200 into the first sliding slot 110 of the expansion slot 100 in advance to achieve alignment.
Fig. 5 is an exploded view of the expansion card plugging auxiliary device 200 provided in the embodiment of the present application, and the expansion card plugging auxiliary device 200 is described in detail below with reference to fig. 5.
The expansion card insertion and extraction auxiliary device 200 may include a fixing block 220 and two pairs of profiled expansion bars 230.
A pair of limiting sliding grooves 240 are drilled at the lower end of the fixing block 220, a pair of circular sliding blocks 241 are connected in each of the two limiting sliding grooves 240 in a sliding manner, the lower end of each circular sliding block 241 is fixedly connected with one end of the special-shaped telescopic rod 230, and the special-shaped telescopic rod 230 is connected with a locking screw 250 for adjusting the length of the special-shaped telescopic rod 230; a fixing groove 260 is drilled at the other end of the special-shaped telescopic rod 230, a one-way bearing 270 is fixedly connected to the inner wall of the fixing groove 260, a fixing column 280 is fixedly connected to an inner ring of the one-way bearing 270, the lower end of the fixing column 280 is fixedly connected to an insertion block 210 matched with the first sliding groove 110 in the expansion slot 100, and the insertion block 210 is used for aligning the expansion card 20 clamped by the expansion card insertion and extraction auxiliary device 200 with the expansion slot 100; the lower end of the fixing block 220 is fixedly connected with a pressing block 290, and the pressing block 290 is located between the special-shaped telescopic rods 230, so as to realize the insertion and extraction of the expansion card 20 clamped by the expansion card insertion and extraction auxiliary device 200, and improve the insertion and extraction efficiency of the expansion card.
In order to more clearly show the structure of the expansion card plugging auxiliary device 200, fig. 6 shows a partial sectional view of the expansion card plugging auxiliary device 200, and fig. 7 shows a connection relationship between the plug 210 and the special-shaped telescopic rod 230 in the expansion card plugging auxiliary device 200.
It is understood that the size of the gap between the profile rods 230 can be changed by rotating the profile rods 230, and then the profile rod 290 can be a rod having a vertical section with an elliptical-like cross-sectional shape; the length of the expansion card 20 which can be clamped by the special-shaped telescopic rod 230 can be changed by sliding the special-shaped telescopic rod 230 to drive the circular sliding block 241 connected with the special-shaped telescopic rod 230 to slide in the limiting sliding groove 240; the length of the special-shaped telescopic rod 230 can be adjusted adaptively by adjusting the tightness of the locking screw 250, the range can be set to be 16 cm to 32 cm, and the special-shaped telescopic rod is suitable for the widths of full-height full-length PCI-E expansion cards and half-height half-length PCI-E expansion cards, namely, the expansion cards 20 of most common PCI-E interface types can be met.
In this way, the special-shaped expansion link 230 in the expansion card insertion and extraction auxiliary device 200 can be changed, so that the expansion card 20 can be flexibly clamped by the expansion card insertion and extraction auxiliary device 200.
It should be noted that the special-shaped expansion link 230 does not affect the rotation of the circular slider 241 in the limiting sliding groove 240, and the circular slider 241 does not fall off from the limiting sliding groove 240, and does not affect the rotation of the special-shaped expansion link 230, and does not affect the normal function of the special-shaped expansion link 230.
In the specific implementation, the surface of the special-shaped telescopic rod 230 can be coated with elastic paint, so that the surface of the special-shaped telescopic rod 230 has certain elasticity and is not easy to damage the clamped expansion card 20.
As an example, the total length of the fixing block 220 in the expansion card plugging auxiliary device 200 may be 34 cm, which may satisfy the requirement of the expansion card 20 (length of 31.2 cm) of the longest PCI-E interface type appearing in the market.
It can be understood that the fixing block 220 is a force applying component for a user to insert and pull the expansion card 20, so that an auxiliary handle can be further installed on the upper surface of the fixing block 220, and the pressing force area is larger after the auxiliary handle is installed, which is more labor-saving.
In addition, in order to prevent damage to the expansion card 20 during the pressing process, the material of the pressing block 290 may be a silicone material, and the surface of the pressing block 290 may be coated with an anti-fouling layer. Thus, the expansion card 20 is not easily damaged, and the expansion card 20 is not easily soiled.
After the expansion slot 100, the expansion card plugging auxiliary device 200, and the expansion card plugging system 10 provided in the embodiments of the present application are introduced, the following exemplary operations of the above devices will be described.
In a specific use, the process of inserting the expansion card 20 may include: firstly, rotating the special-shaped telescopic rods 230 and adjusting the nearest distance between the seams of the two special-shaped telescopic rods 230 to the maximum value; then, the expansion card 20 is placed between the two special-shaped expansion rods 230; then, the inserting block 210 is inserted into the first sliding groove 110, so that the expansion card 20 and the expansion slot 100 are aligned, at this time, the inserting block 210 cannot rotate, due to the existence of the one-way bearing 270, the special-shaped telescopic rods 230 can be rotated in a one-way manner, and the distance between the two special-shaped telescopic rods 230 is adjusted, so that the expansion card 20 is not easy to shake, clamping is not needed, and the expansion card plugging auxiliary device 200 can be conveniently taken out after the expansion card 20 is inserted; at this time, the expansion card 20 can be pressed into the slot of the expansion slot 100 by directly pressing the fixing block 290 without locking the locking screw 20. Alternatively, when the height of the expansion card 20 is low, the insertion block 210 does not need to be inserted into the first sliding slot 110, and the positioning expansion plate 181 ejected by the compression spring 190 in the third sliding slot 180 is used to achieve the alignment.
The process of pulling out the expansion card 20 may include: firstly, the length of the special-shaped telescopic rod 230 can be adjusted and the special-shaped telescopic rod 230 is locked by the locking screw 250; then, the inserting block 210 is inserted into the first sliding slot 110, so that the inserting block 210 presses the first sliding block 110, the second sliding block 121 is pulled to rise, and the jacking block 150 on the second sliding block 121 can jack up the expansion card 20 with assistance; then, adjusting the distance between the two special-shaped telescopic rods 230 to clamp the expansion card 20; finally, after the expansion card 20 is clamped by the two pairs of the special-shaped telescopic rods 230, the expansion card 20 can be easily pulled out of the expansion slot 100 by pulling the expansion card insertion and extraction auxiliary device 200.
Therefore, in the embodiment of the application, from the perspective of convenience in plugging and unplugging the expansion card by a user, a new expansion slot, an auxiliary device for plugging and unplugging the expansion card and an expansion card plugging and unplugging system are provided, and due to the structural design of the control slot and the auxiliary effect of the auxiliary device for plugging and unplugging the expansion card, the difficulty in plugging and unplugging the expansion card is greatly reduced, so that the user can conveniently, quickly and accurately plug and unplug the expansion card from the expansion slot, further, the main board and the expansion card cannot be damaged at all, the service lives of the expansion card and the main board are prolonged, and the reliability and the safety of the main board and the expansion card of a computer can be ensured on the basis of providing the convenience for the user.
