Two sliding blocks symmetrically slide at two ends of the socket along the insertion direction parallel to the memory bank, and racks B meshed with the gears B on the same side are mounted on the sliding blocks; the upper end of each sliding block is rotatably matched with a telescopic rod, and an n-shaped pressing block for pressing the memory bank into the socket is arranged at the upper end of the telescopic rod through a connecting plate; a spring B for stretching and restoring the telescopic rod is arranged in the telescopic rod; the telescopic rod, the sliding block and the socket are provided with structures for locking the relative position of the sliding block and the socket when the corresponding n-type pressing block swings away from the upper part of the clamping groove along with the rotating telescopic rod.

As a further improvement of the technology, two sliding chutes a are symmetrically formed on the inner walls of the two sides of the clamping groove of the socket, and the two clamping bars respectively slide in the two sliding chutes a; two trapezoidal guide blocks are symmetrically arranged at two ends of each clamping strip, and the two trapezoidal guide blocks on each clamping strip slide in the two trapezoidal guide grooves on the inner wall of the corresponding sliding groove A respectively; two racks A at two ends of each holding strip respectively slide in two sliding chutes B on the inner wall of the corresponding sliding chute A; the conductive contact A is fixedly arranged in the contact groove in the holding strip; the bottom of the holding strip is provided with a plurality of movable grooves A communicated with the contact sheet grooves along the length direction, and the elastic metal sheet connecting the conductive contact sheet A and the corresponding contact pin moves in the corresponding movable grooves A.

Compared with the traditional PCI slot, the two telescopic rods compress the memory bank inserted into the socket through the two n-type pressing blocks, poor contact between the two clamping bars in the socket and the memory bank caused by the fact that the memory bank inserted into the socket is loosened with the socket under strong external vibration is avoided, and hard related electronic equipment is continuously and normally used. When the vibration is influenced, the swinging memory bank is caused by the vibration to enable the two clamping bars to move back and forth away from the memory bank, the springs A on the two clamping bars are further compressed and store energy, and the two clamping bars drive the memory bank to go deep into the socket continuously through a series of transmission; because the reaction of the spring B in the telescopic link that is stretched makes two sliders pull out the trend of the direction motion from the DRAM in taking place the case, two sliders drive two battens through a series of transmission and want to take place relative motion and extrude the DRAM, simultaneously, spring A by further compression has increased the extrusion force of two battens to the DRAM, make the cooperation of DRAM and socket inseparabler, thereby guarantee under the vibration influence the contact between DRAM and the conductive contact A on two battens is inseparabler, vibrate two battens more inseparabler to the extrusion of DRAM more.

When the spring A in the invention is completely failed, the clamping force of the two clamping strips to the memory strip is reduced; under the action of the stretched telescopic rod, a spring B in the telescopic rod drives the memory bank to quickly contact the bottom in the slot through the outer rod, the connecting plate and the n-type pressing block; meanwhile, the spring B in the stretching telescopic rod releases energy under the unconstrained condition, the spring B drives the two clamping bars to move in opposite directions through a series of transmission and continuously clamps the memory bank, and therefore the memory bank is guaranteed to be still in good contact with the two clamping bars under the condition that the spring A is completely failed.

As shown in fig. 2 and 9, each holding strip 8 is uniformly provided with a plurality of springs a16 for resetting the holding strip; as shown in fig. 11, two L-shaped racks a15 are symmetrically installed at two ends of each holding strip 8; as shown in fig. 3 and 4, two transmission shafts 17 are symmetrically and rotatably fitted at two ends of the socket 1, and a gear a18 and a gear B19 are coaxially mounted on each transmission shaft 17; as shown in fig. 4 and 9, the gear a18 is located between the two racks a15 on the same side, and the gear a18 is meshed with the two racks a15 at the same time.

As shown in fig. 3, 4 and 6, two sliding blocks 21 are symmetrically slid at two ends of the socket 1 along a direction parallel to the insertion direction of the memory bank 40, and a rack B20 meshed with the gear B19 on the same side is installed on the sliding blocks 21; as shown in fig. 3, 5 and 13, an expansion link 32 is rotatably fitted to the upper end of each slider 21, and an n-type press block 39 for pressing a memory bank 40 into the socket 1 is mounted on the upper end of the expansion link 32 through a connecting plate 38; as shown in fig. 5, the telescopic rod 32 is internally provided with a spring B37 for telescopic return; as shown in fig. 5, 6 and 14, the telescopic rod 32, the sliding block 21 and the socket 1 are provided with structures for locking the relative positions of the sliding block 21 and the socket 1 when the corresponding n-shaped pressing block 39 swings away from the upper part of the card slot 2 along with the rotating telescopic rod 32.

As shown in fig. 2 and 7, two sliding grooves A3 are symmetrically formed on the inner walls of the two sides of the slot 2 of the socket 1, and the two holding bars 8 respectively slide in the two sliding grooves A3; as shown in fig. 8, 9 and 10, two trapezoidal guide blocks 14 are symmetrically installed at two ends of each holding strip 8, and the two trapezoidal guide blocks 14 on each holding strip 8 respectively slide in the two trapezoidal guide grooves 6 on the inner wall of the corresponding sliding groove a 3; as shown in fig. 1, 7 and 10, two racks a15 at two ends of each gib 8 slide in two slide grooves B5 on the inner wall of the corresponding slide groove A3 respectively; as shown in fig. 10 and 11, conductive contact a12 is fixedly mounted in contact slot 9 in gib 8; as shown in fig. 2, 7 and 8, the bottom of the gib 8 is opened with a plurality of movable grooves a10 along its length direction, which are communicated with the contact grooves 9, and the elastic metal sheet 13 connecting the conductive contact a12 and the corresponding pin 7 is movable in the corresponding movable groove a 10. The matching of the trapezoid guide groove 6 and the trapezoid guide block 14 plays a positioning and guiding role for the sliding of the holding strip 8 in the sliding groove A3.

As shown in fig. 5 and 6, the slider 21 slides in a guide seat 26 mounted on the socket 1; as shown in fig. 14, the upper end surface of the slider 21 is provided with a circular groove 22; as shown in fig. 5, one end of the inner rod 33 of the telescopic rod 32 rotates in the circular groove 22, and the rotating round block 30 installed on the inner rod 33 rotates in the circular groove 23 on the inner wall of the circular groove 22 along with the inner rod 33; as shown in fig. 5 and 13, the connecting plate 38 is mounted on the outer rod 35 of the telescopic rod 32; as shown in fig. 6, 12 and 14, the limiting block 31 mounted on the cylindrical surface of the rotating round block 30 swings around the central axis of the telescopic rod 32 in the movable groove B24 on the inner wall of the ring groove 23 and the limiting groove 28 on the inner wall of the guide seat 26; as shown in fig. 6 and 13, two guide blocks a25 are symmetrically installed on both sides of the slider 21, and the two guide blocks a25 slide in two guide grooves a27 on the inner wall of the corresponding guide seat 26. The rotational cooperation of the annular groove 23 and the rotary knob 30 ensures that the telescopic rod 32 only rotates relative to the slide 21 and does not move axially relative to the slide 21. The engagement of the guide block a25 with the guide groove a27 serves as a positioning guide for the slide of the slider 21 in the guide holder 26.

As shown in fig. 4, the transmission shaft 17 is rotatably engaged with a door frame 53 installed on the same side of the socket 1; as shown in fig. 7 and 8, the heat dissipation grooves 4 corresponding to the conductive contacts a12 one by one are formed on the upper surfaces of the two sides of the card slot 2 on the socket 1, and the heat dissipation grooves 4 are favorable for quickly releasing heat generated by the electrical connection between a large number of conductive contacts a12 and conductive contacts B41 in the socket 1 to the outside, so as to prevent the socket 1 from being burned out due to overheating during the process of matching with the memory bank 40.

As shown in fig. 5, the telescopic rod 32 comprises an outer rod 35 and an inner rod 33 sliding in the outer rod 35; two guide blocks B34 are symmetrically arranged on the inner rod 33, and two guide blocks B34 respectively slide in two guide grooves B36 on the inner wall of the corresponding outer rod 35. The engagement of the guide block B34 with the guide groove plays a positioning and guiding role in the sliding of the inner lever 33 within the outer lever 35, and prevents the relative rotation between the outer lever 35 and the inner lever 33.

When the two holding strips 8 slide close to each other, the two holding strips 8 simultaneously drive the two sliding blocks 21 to move along the direction that the memory strip 40 is pulled out of the socket 1 through a series of transmission; when the two holding strips 8 slide away from each other, the two holding strips 8 simultaneously drive the two sliding blocks 21 to move along the direction in which the memory bank 40 is inserted into the socket 1 through a series of transmission.

The working process of the invention is as follows: in the initial state, the memory stick 40 is not inserted into the socket 1, and the spring a16 for returning the two holding sticks 8 is in a compressed state; the trapezoid guide blocks 14 on the holding strip 8 are positioned at the extreme positions of the corresponding trapezoid guide grooves 6; the two n-type pressing blocks 39 are not opposite to the clamping grooves 2 of the socket 1; the two stoppers 31 are respectively located in the stopper grooves 28 of the corresponding guide seats 26, and the relative positions of the two sliders 21 and the corresponding guide seats 26 are temporarily fixed.

When the memory bar 40 is inserted between the two clamping bars 8 in the slot 2 of the socket 1, because the two limit blocks 31 are simultaneously positioned in the limit grooves 28 on the inner walls of the corresponding guide seats 26, the relative positions of the two slide blocks 21 and the corresponding guide seats 26 are simultaneously fixed, and the two slide blocks 21 and the corresponding guide seats 26 cannot slide relatively under the action of external force; the two sliding blocks 21 respectively prevent the two clamping bars 8 from moving back to back under the action of the memory bar 40 through the corresponding rack B20, the gear B19, the transmission shaft 17, the gear A18 and the two racks A15 on the same side of the two clamping bars 8; with the memory bank 40 inserted between the two clamping bars 8 with a suitable force, the two clamping bars 8, which remain stationary, provide an effective grip on the memory bank 40 entering between them and ensure that the contact pads B41 on the memory bank 40 make good contact with the contact pads a12 on the two clamping bars 8.

After the memory bank 40 is completely inserted into the socket 1 in the initial state, the distance between the two n-type press blocks 39 and the socket 1 is far smaller than the distance between the end surface of the exposed end of the memory bank 40 and the socket 1; then, one hand sequentially rotates the two telescopic rods 32, the two telescopic rods 32 sequentially drive the corresponding n-shaped pressing blocks 39 to synchronously rotate around the central axis of the telescopic rods 32 in the direction opposite to the clamping groove 2 through the corresponding connecting plates 38, and the telescopic rods 32 drive the corresponding limiting blocks 31 to gradually swing out of the limiting grooves 28 on the corresponding guide seats 26 through the corresponding rotating round blocks 30; meanwhile, the other hand presses the n-type pressing block 39 relative to the corresponding connecting plate 38 towards the direction in which the memory bank 40 is pulled away from the socket 1, so that the distance between the n-type pressing block 39 and the socket 1 is larger than the distance between the end face of the exposed end on the memory bank 40 and the socket 1; in the process that the n-shaped pressing block 39 is pressed, the n-shaped pressing block 39 drives the outer rod 35 of the corresponding telescopic rod 32 to stretch relative to the inner rod 33 through the corresponding connecting plate 38, and the spring B37 inside the telescopic rod 32 is stored with energy by the pulling rope.

In the process of pressing the n-type pressing block 39 from the initial state to the direction of pulling the memory bank 40 away from the socket 1, since the trapezoidal guide blocks 14 on the two clamping bars 8 are respectively located at the extreme positions of the corresponding trapezoidal guide grooves 6 to prevent the two clamping bars 8 from approaching each other, the two clamping bars 8 prevent the inner rod 33 of the telescopic rod 32 from moving to the direction of pulling the memory bank 40 away from the socket 1 under the action of the stretched spring B37 through the rack a15, the gear a18, the transmission shaft 17, the gear B19, the rack B20 and the sliding block 21, and the pressed n-type pressing block 39 drives the outer rod 35 of the telescopic rod 32 through the connecting plate 38 to move only to the direction of pulling the memory bank 40 away from the socket 1 relative to the inner rod 33 of the telescopic rod 32.

When the n-type press block 39 reaches the position right opposite to the memory bank 40, the limit block 31 arranged on the rotary round block 30 is completely swung out of the limit groove 28 on the corresponding guide seat 26 and the limit on the relative movement of the corresponding slide block 21 and the corresponding guide seat 26 is released; at this time, the acting force on the n-type presser 39 is removed, and the n-type presser 39 is instantaneously fitted with the memory bank 40 and presses the memory bank 40 by the action of the stretched spring B37; at this point, the spring B37 is further tensioned to store energy relative to its initial state by the action of the plunger 40. The stretched spring B37 in the telescopic rod 32 drives the corresponding n-type pressing block 39 to extrude the memory bank 40 into the socket 1 through the outer rod 35 of the telescopic rod 32 and the corresponding connecting plate 38, so that good contact between the memory bank 40 and the conductive contact piece A12 on the two clamping bars 8 in the socket 1 is ensured.

When the micro vibration occurs, the memory bank 40 does not swing relative to the socket 1 due to the pressing of the two n-type press blocks 39 on the memory bank 40; when large and violent vibration occurs, the memory bank 40 is likely to swing relative to the socket 1, and the memory bank 40 which swings at the moment can make the two clamping bars 8 move towards two sides; two racks A15 on the same side of the two holding strips 8 drive a gear A18 meshed with the two holding strips to rotate, the gear A18 drives a gear B19 to synchronously rotate through a transmission shaft 17, and the gear B19 drives the slide block 21 on the same side to move towards the direction that the memory strip 40 is inserted into the socket 1 through the corresponding rack B20; the sliding block 21 drives the n-type pressing block 39 to move towards the direction that the memory bank 40 is inserted into the socket 1 sequentially through the rotating round block 30, the telescopic rod 32 and the connecting plate 38, and the n-type pressing block 39 further presses the memory bank 40, so that the memory bank 40 is inserted between the two clamping bars 8 more deeply; under the action of the spring B37, the n-type pressing block 39 drives the memory bar 40 to always keep good contact with the two clamping bars 8.

If the springs A16 for resetting the two clamping bars 8 are totally failed due to damage, the memory bar 40 instantaneously bottoms under the action of the spring B37 in a stretching state; meanwhile, the springs B37 in the two telescopic rods 32 respectively drive the corresponding racks B20 to move towards the direction that the memory bank 40 is pulled away from the socket 1 through the corresponding inner rod 33, the rotary round block 30 and the sliding block 21 at the same time, and the two racks B20 respectively drive the two racks A15 which are meshed with the corresponding racks B19 through the corresponding gear B19, the transmission shaft 17 and the gear A18 and are positioned at the same side of the clamping bank 8 to move oppositely; the two holding strips 8 slide towards each other under the driving of the corresponding racks A15 and effectively extrude the memory bank 40 located therebetween, so that the two holding strips 8 still keep good contact with the memory bank 40 after the spring A16 completely fails, and the continuous normal use of the related electronic equipment is ensured.

When the memory bank 40 is pulled out from the socket 1, the two n-type press blocks 39 are sequentially operated; the operation for each n-type compact 39 is as follows: pressing the n-type pressing block 39 towards the direction that the internal memory bank 40 is pulled away from the socket 1 relative to the internal rod 33 of the corresponding telescopic rod 32 by one hand, so that the distance between the n-type pressing block 39 and the socket 1 is larger than the distance between the end surface of the exposed end of the internal memory bank 40 and the socket 1, the n-type pressing block 39 is separated from the internal memory bank 40, and the n-type pressing block 39 stretches the spring B37 in the telescopic rod 32 through the pressing block and the external rod 35 of the telescopic rod 32 to store energy; then the other hand rotates the stretched telescopic rod 32 to the initial state, the telescopic rod 32 sequentially drives the corresponding n-shaped pressing block 39 to synchronously rotate around the central axis of the telescopic rod 32 to the direction of the initial position through the corresponding connecting plate 38, and the telescopic rod 32 sequentially drives the corresponding limiting block 31 to gradually swing into the limiting groove 28 on the corresponding guide seat 26 through the corresponding rotating round block 30; in the process of pressing the n-type pressing block 39 in the direction of pulling the memory bank 40 away from the socket 1, since the two clamping bars 8 extrude the memory bank 40 located therein, and the memory bank 40 prevents the two clamping bars 8 from approaching each other, the two clamping bars 8 prevent the inner rod 33 rotating on the sliding block 21 from moving in the direction of pulling the memory bank 40 away from the socket 1 under the action of the spring B37 in the stretched telescopic rod 32 through a series of transmissions, and the pressed n-type pressing block 39 drives the outer rod 35 of the telescopic rod 32 through the connecting plate 38 to only move in the direction of pulling the memory bank 40 away from the socket 1 relative to the inner rod 33 of the telescopic rod 32.

When the n-type pressing block 39 swings to the initial position along with the telescopic rod 32, the limiting block 31 arranged on the rotary round block 30 completely swings into the limiting groove 28 on the corresponding guide seat 26 and restores the limitation on the relative movement of the sliding block 21 and the corresponding guide seat 26; at this time, the acting force on the n-shaped pressing block 39 is removed, and under the action of the spring B37 in the stretched telescopic rod 32, the n-shaped pressing block 39, the connecting plate 38 and the outer rod 35 of the telescopic rod 32 are instantaneously reset relative to the inner rod 33 of the telescopic rod 32; the extension pole 32 and its internal spring B37 return to the initial state.

Then, the memory bank 40 is removed from the socket 1.

In conclusion, the beneficial effects of the invention are as follows: the two telescopic rods 32 in the invention compress the memory bank 40 inserted into the socket 1 through the two n-type press blocks 39, thereby avoiding poor contact between the two holding bars 8 in the socket 1 and the memory bank 40 due to the fact that the memory bank 40 inserted into the socket 1 is loosened with the socket 1 under the strong external vibration, and further avoiding the continuous normal use of the hard related electronic equipment. When the invention is influenced by vibration, the swinging memory bank 40 caused by the vibration enables the two clamping bars 8 to move back and forth away from the memory bank 40, the springs A16 on the two clamping bars 8 are further compressed and store energy, and the two clamping bars 8 drive the memory bank 40 to go deep into the socket 1 through a series of transmission; because the reaction of the spring B37 in the stretched telescopic rod 32 makes the two sliding blocks 21 move in the direction that the generation box is pulled away from the memory bank 40, the two sliding blocks 21 drive the two clamping bars 8 to move in opposite directions through a series of transmission and extrude the memory bank 40, and meanwhile, the further compressed spring A16 increases the extrusion force of the two clamping bars 8 on the memory bank 40, so that the matching of the memory bank 40 and the socket 1 is tighter, thereby ensuring that the contact between the memory bank 40 and the conductive contact sheets A12 on the two clamping bars 8 is tighter under the influence of vibration, and the tighter the extrusion of the two clamping bars 8 on the memory bank 40 is, the tighter the extrusion of the memory bank is when the two clamping bars 8 are vibrated.

When the spring a16 of the present invention is completely deactivated, the clamping force of the two clamping bars 8 to the memory bar 40 is reduced; under the action of the stretched telescopic rod 32, the spring B37 in the telescopic rod 32 drives the memory bank 40 to quickly bottom in the slot through the outer rod 35, the connecting plate 38 and the n-type press block 39; meanwhile, the spring B37 in the stretching telescopic rod 32 releases energy under the unconstrained condition, and the spring B37 drives the two clamping bars 8 to move in opposite directions through a series of transmission and continuously clamps the memory bank 40, so that the memory bank 40 is ensured to be still in good contact with the two clamping bars 8 under the condition that the spring a16 completely fails. In addition, the memory bank 40 and the two holding bars 8 which are staggered with each other in the vibration process clean dust deposited on the conductive contact piece A12 and the conductive contact piece B41 due to long-time use, so that the surfaces of the conductive contact piece A12 and the conductive contact piece B41 are ensured to be clean, and good contact between the conductive contact piece A12 and the conductive contact piece B41 is further ensured.
