Description

Hardware slot for electronic equipment

Technical Field

The invention belongs to the field of hardware slots, and particularly relates to a hardware slot for electronic equipment.

Background

In the traditional matching of the slot and the memory bank, if the quality of the slot and the memory bank is unqualified or the slot and the memory bank are worn to a certain extent after long-term use, looseness occurs between the slot and the memory bank, and a golden finger on the slot and a golden finger on the memory bank cannot be in good contact with each other, so that a series of problems are caused to related electronic equipment.

Moreover, the traditional slot and the memory bank are matched to loosen under the action of frequent vibration, so that the contact between the golden fingers on the slot and the golden fingers on the memory bank is poor, and the memory bank is burnt and damaged under severe conditions. In addition, the golden finger in the traditional slot is arched outwards to deform so as to clamp the memory bank inserted into the golden finger; because the golden finger on the slot participates in the electric connection all the time, the golden finger on the slot can be oxidized after being used for a long time, and the oxidized golden finger is easily damaged due to the reduction of the elasticity of the oxidized golden finger, so that poor contact between the slot and the memory bank is caused.

In view of the above problems of the conventional socket, it is necessary to design a hardware socket for electrical equipment that can effectively solve the problem of poor contact caused by the quality problem, frequent vibration or aging and oxidation when the conventional socket is matched with a memory bank.

The present invention is directed to a hardware socket for an electronic device to solve the above problems.

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 round rod, and a pressure mechanism for pressing the memory bank into the socket is arranged at the upper end of the round rod through a connecting plate; the round rod, the sliding block and the socket are provided with structures for locking the relative positions of the sliding block and the socket when the corresponding pressure mechanism swings away from the upper part of the clamping groove along with the rotating round rod; when the two clamping strips slide back to back, the two round rods respectively drive the corresponding pressure applying mechanisms to press the memory strips into the socket.

The pressing mechanism comprises a disc, a telescopic sleeve A, an inner rod A, a limiting block B, a spring B, a driving ring, a telescopic rod, a spring C, n type pressing block and a spring D, wherein the disc is installed on a corresponding connecting plate, and the inner rod A is installed in the telescopic sleeve A at the center of the lower end of the disc and slides in the direction parallel to the direction in which the memory bank is inserted into the socket; a driving ring is nested and slides on the telescopic sleeve A; the upper end of the driving ring is connected with the disc through four telescopic rods which are uniformly distributed in the circumferential direction, and the lower end of the driving ring is connected with an n-shaped pressing block which is arranged at the lower end of the inner rod A and is matched with the memory bank through a spring D which is nested on the telescopic sleeve A and is pre-pressed; a spring C for stretching and restoring the telescopic rod is arranged in the telescopic rod; t-shaped limiting blocks B respectively slide in two T-shaped sliding grooves C on the side wall of the telescopic sleeve A along the radial direction, and two springs B for resetting the limiting blocks B are symmetrically arranged on each limiting block B; the limiting block B is matched with an outward-expanding conical surface B at the lower end of the inner wall of the driving ring, and insections B on the inner side of the limiting block B are matched with insections A on the inner rod A so as to limit the relative movement of the inner rod A and the telescopic sleeve A.

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; the transmission shaft is rotatably matched with a door frame arranged on the same side of the socket. The matching of the trapezoidal guide groove and the trapezoidal guide block plays a role in positioning and guiding the sliding of the holding strip in the corresponding sliding groove A.

As a further improvement of the technology, the inner rod a is symmetrically provided with two guide blocks B which respectively slide in two guide grooves B on the inner wall of the telescopic sleeve a; the telescopic rod consists of a telescopic sleeve B and an inner rod B sliding in the telescopic sleeve B; two guide blocks C are symmetrically arranged on the inner rod B and respectively slide in two guide grooves C on the inner wall of the corresponding telescopic sleeve B. The guide block B is matched with the guide groove B to play a positioning and guiding role in the sliding of the inner rod A in the telescopic sleeve A. The guide block C is matched with the guide groove C to play a positioning and guiding role in the sliding of the inner rod B in the telescopic sleeve B.

As a further improvement of the present technology, when the two clamping bars move towards the two sides of the memory bank inserted into the socket in an opposite manner, the round bar drives the memory bank to continue to enter the socket by the pressing mechanism by a displacement amount larger than that of the round bar, so as to ensure that when the two clamping bars slide towards the two sides in an opposite manner under the action of the memory bank oscillating due to vibration to detach from the memory bank, the two clamping bars drive the pressing mechanism to move towards the socket at a higher speed through a series of transmissions, and the larger speed difference between the memory bank and the two clamping bars causes the wedge-shaped end with the conductive contact B on the memory bank to be always attached to and press the inclined surfaces of the two clamping bars, so that the conductive contact B on the memory bank is always kept in good contact with the conductive contact a on the clamping bars, and poor contact caused by loose fit between the memory bank and the slot due to vibration is avoided.

As a further improvement of the technology, the slider slides in a guide seat mounted on the socket; the upper end surface of the sliding block is provided with a circular groove; one end of the round rod rotates in the round groove, and a rotating round block arranged on the round rod rotates in a ring groove on the inner wall of the round groove along with the round rod; a limiting block A arranged on the cylindrical surface of the rotary round block swings in a movable groove B on the inner wall of the ring groove and a limiting groove on the inner wall of the guide seat around the central axis of the round rod; two springs B on the limiting block B are positioned in the corresponding sliding grooves C; one end of the spring B is connected with the inner wall of the corresponding chute C, and the other end of the spring B is connected with the corresponding limiting block B. The circular groove is matched with the rotary round block in a rotating mode to ensure that the round rod and the sliding block only rotate relatively and do not move axially relatively.

As a further improvement of the technology, two guide blocks A are symmetrically arranged on two sides of the sliding block, and the two guide blocks A respectively slide in two guide grooves A on the inner wall of the corresponding guide seat. The guide block A and the guide groove A are matched to play a role in positioning and guiding the sliding of the sliding block in the guide seat.

As a further improvement of the technology, the upper surfaces of two sides of the clamping groove on the socket are provided with a plurality of radiating grooves which are in one-to-one correspondence with the conductive contact pieces A, the radiating grooves are communicated with the contact piece grooves where the corresponding conductive contact pieces A are located, and the portions of the conductive contact pieces A are arched and located in the corresponding radiating grooves, so that heat generated by electric connection of a large number of conductive contact pieces A and conductive contact pieces B in the socket can be released from the radiating grooves to the outside quickly, and the socket is prevented from being burnt out due to overheating in the matching process of the socket and the memory bank. The dustproof net covers the notch of the radiating groove, and effectively blocks dust which enters the socket through the radiating groove to the outside, so that poor contact caused by the fact that a plurality of conductive contact pieces in the socket cover the dust for a long time is avoided.

As a further improvement of the technology, the upper end of the outer side of the limit block B is provided with a conical surface A matched with the conical surface B, so that a kinematic pair between the limit block B and the drive ring is converted from a high pair to a low pair, and the abrasion between the conical surface B on the drive ring and the limit block B is reduced.

Compared with the traditional electronic equipment slot, the invention presses the memory bank inserted into the socket towards the direction of inserting the memory bank into the socket through the two pressure applying mechanisms which are symmetrically distributed and in a pre-compression state, and because the pressure applying mechanisms press the memory bank inserted into the socket, the spring D inside the socket is in a state after manual compression, the spring D presses the memory bank to be always in close contact with the conductive contact A on the two clamping bars through the n-type pressing block, thereby ensuring the good contact of the memory bank and the conductive contact A in the socket; the device effectively prevents the n-type pressing block from pressing the memory bank with the wedge-shaped insertion end to continuously go deep into the socket and keep close and good contact with the conductive contact pieces on the two clamping bars under the action of the pre-compressed spring D when the two clamping bars slide towards the two sides of the memory bank under the action of the memory bank which swings due to vibration and try to be separated from the memory bank; meanwhile, the two clamping bars sliding to the two sides drive the corresponding pressure applying mechanisms to move towards the direction of the memory bank inserted into the socket through a series of transmission respectively, so that the displacement difference between the pressure applying mechanisms and the memory bank is reduced, the elongation of a spring D in the pressure applying mechanisms, which is caused by the movement of the memory bank, for releasing energy is effectively reduced, and the pressure applying mechanisms still have enough pressure on the memory bank after the relative positions of the memory bank and the two clamping bars are changed due to vibration, so that the memory bank is always kept in good contact with the conductive contact pieces A on the two clamping bars.

In the relative motion process between the memory bank and the two holding strips due to vibration, the dust adsorbed on the conductive contact piece A and the conductive contact piece B due to long-time use is effectively cleaned due to mutual friction and dislocation of the conductive contact piece B on the memory bank and the conductive contact piece A on the two holding strips, so that good contact of the conductive contact pieces on the memory bank and the two holding strips is further ensured. The conductive contact A in the slot is not easy to damage and lose efficacy due to oxidation.

Because the spring A used for resetting the two clamping bars does not participate in electric connection, the spring A is oxidized to a lower degree in the working process, is not easy to deform and fatigue or damage, has a better anti-vibration effect, can effectively prevent the two clamping bars from sliding to two sides under the action of the memory bar which swings due to vibration to a certain degree, and also ensures that the conductive contact pieces A on the two clamping bars are kept in good contact with the memory bar under the vibration condition. Even if the springs a for the return of the two gibs all fail, in this case the two gibs lose the support of the springs a; under the effect of the spring D in a compression state in the pressure applying mechanism, the memory bank quickly contacts the bottom in the socket, the spring D capable of releasing energy simultaneously drives the rack B to move towards the direction that the memory bank is pulled out of the socket through a series of transmission belts, and the rack B drives the two clamping bars to extrude the memory bank in opposite directions through a series of transmission belts, so that the conductive contact piece A on the two clamping bars is still kept in close and good contact with the memory bank under the condition that the spring A for resetting the two clamping bars is completely failed.

In addition, the invention still keeps pressing the memory bank under the condition that the spring D in the pressing mechanism completely fails, and ensures that the memory bank still realizes good contact with the conductive contact pieces A on the two clamping bars under the condition that the pressing mechanism fails. The invention has simple structure and better use effect.

As shown in fig. 1 and 2, 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 55; as shown in fig. 1, 4 and 6, a rack B20 meshed with the gear B19 on the same side is arranged on the slide block 21; as shown in fig. 1 and 2, a round bar 32 is rotatably fitted on the upper end of each slider 21, and a pressing mechanism 34 for pressing the memory bank 55 into the socket 1 is mounted on the upper end of the round bar 32 through a connecting plate 33; as shown in fig. 5, 11 and 13, the round bar 32, the slider 21 and the socket 1 have a structure for locking the relative position of the slider 21 and the socket 1 when the corresponding pressing mechanism 34 swings away from the upper side of the card slot 2 along with the rotating round bar 32; as shown in fig. 1 and 2, when the two clamping bars 8 slide back to back, the two round rods 32 respectively drive the corresponding pressing mechanisms 34 to press the memory bars 55 into the socket 1.

As shown in fig. 14, the pressing mechanism 34 includes a disc 35, a telescopic sleeve a36, an inner lever a39, a stopper B42, a spring B45, a driving ring 46, a telescopic rod 48, a spring C58, an n-shaped pressing block 53, and a spring D54, wherein as shown in fig. 1, 2, and 15, the disc 35 is mounted on the corresponding connecting plate 33, and the inner lever a39 is slid in a telescopic sleeve a36 mounted at the center of the lower end of the disc 35 in a direction parallel to the insertion direction of the memory bank 55 into the socket 1; as shown in fig. 14 and 16, the driving ring 46 is nested and slides on the telescopic sleeve A36; as shown in fig. 1 and 14, the upper end of the driving ring 46 is connected with the circular disc 35 through four expansion rods 48 which are uniformly distributed in the circumferential direction, and the lower end of the driving ring 46 is connected with an n-type press block 53 which is arranged at the lower end of the inner rod a39 and is matched with the memory bank 55 through a spring D54 which is nested on an expansion sleeve a36 and pre-pressed; as shown in fig. 15, the telescopic rod 48 is internally provided with a spring C58 for telescopically restoring the telescopic rod; as shown in fig. 16 and 19, T-shaped limit blocks B42 are respectively and radially slid in two T-shaped chutes C38 on the side wall of the telescopic sleeve a36, and two springs B45 for returning to each limit block B42 are symmetrically installed on each limit block B42; as shown in fig. 16 and 17, the stopper B42 is fitted with an outward flared surface B47 of the lower end of the inner wall of the drive ring 46; as shown in fig. 16, 18 and 20, the insections B43 on the inner side of the stopper B42 cooperate with the insections a40 on the inner rod a39 to restrict the relative movement of the inner rod a39 and the telescoping sleeve a 36.

As shown in fig. 3, 7 and 8, 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. 6, 8 and 9, 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; the two racks A15 at the two ends of each holding strip 8 respectively slide in the two sliding grooves B5 on the inner wall of the corresponding sliding groove A3; as shown in fig. 3 and 9, conductive contact a11 is fixedly mounted in contact slot 9 in gib 8; the bottom of the holding strip 8 is provided with a plurality of movable grooves A10 communicated with the contact groove 9 along the length direction, and the elastic metal sheet 12 connecting the conductive contact A11 and the corresponding contact pin 7 moves in the corresponding movable groove A10; as shown in fig. 4, the drive shaft 17 is rotatably engaged with the gantry 16 mounted on the same side of the socket 1. The matching of the trapezoid guide slot 6 and the trapezoid guide block 14 plays a positioning and guiding role for the sliding of the holding strip 8 in the corresponding sliding slot A3.

As shown in fig. 18 and 19, two guide blocks B41 are symmetrically installed on the inner lever a39, and the two guide blocks B41 slide in two guide grooves B37 on the inner wall of the telescopic sleeve a36 respectively; as shown in fig. 15, the telescopic rod 48 is composed of a telescopic sleeve B49 and an inner rod B51 sliding in the telescopic sleeve B49; two guide blocks C52 are symmetrically arranged on the inner rod B51, and the two guide blocks C52 respectively slide in two guide grooves C50 on the inner wall of the corresponding telescopic sleeve B49. The guide block B41 and the guide groove B37 cooperate to position and guide the sliding of the inner lever a39 in the telescoping sleeve a 36. The guide block C52 and the guide groove C50 cooperate to position and guide the sliding of the inner lever B51 in the telescopic sleeve B49.

As shown in fig. 1, 3 and 14, when the two clamping bars 8 move back to the two sides of the memory bar 55 inserted into the socket 1, the round bar 32 drives the memory bank 55 to go further into the socket 1 through the pressing mechanism 34 by a displacement amount larger than that of the round bar 32, to ensure that when the two clamping bars 8 slide back to back towards both sides under the action of the memory bar 55 swinging due to vibration to be separated from the memory bar 55, the two holding bars 8 drive the pressing mechanism 34 to move into the socket 1 at a higher speed through a series of transmissions, and the larger speed difference between the memory bar 55 and the two holding bars 8 causes the wedge-shaped end of the memory bar 55 with the conductive contact B56 to always cling to and press the inclined surfaces of the two holding bars 8, so that the conductive contact B56 on the memory bank 55 always keeps good contact with the conductive contact a11 on the gib 8, and poor contact caused by loose fit between the memory bank 55 and the slot due to vibration is avoided.

As shown in fig. 5, the slider 21 slides in a guide 26 mounted on the socket 1; as shown in fig. 11, the upper end surface of the slider 21 is provided with a circular groove 22; as shown in fig. 2, 11 and 13, one end of the round rod 32 rotates in the round groove 22, and the rotary round block 30 mounted on the round rod 32 rotates in the ring groove 23 on the inner wall of the round groove 22 along with the round rod 32; as shown in fig. 5, 10 and 12, the limiting block a31 mounted on the cylindrical surface of the rotary round block 30 swings around the central axis of the round 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; two springs B45 on the limiting block B42 are positioned in the corresponding chutes C38; one end of the spring B45 is connected with the inner wall of the corresponding chute C38, and the other end is connected with the corresponding limit block B42. The rotary cooperation of the annular groove 23 and the rotary circular block 30 ensures that the circular rod 32 and the sliding block 21 only rotate relatively and do not move axially relatively.

As shown in fig. 5 and 11, 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 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. 3, 7 and 8, the upper surfaces of the two sides of the card slot 2 on the socket 1 are provided with a plurality of heat dissipation grooves 4 corresponding to the conductive contacts a11 one by one, the heat dissipation grooves 4 are communicated with the contact grooves 9 where the corresponding conductive contacts a11 are located, and the conductive contacts a11 are partially arched and located in the corresponding heat dissipation grooves 4, so that heat generated by the electrical connection between a large number of conductive contacts a11 and conductive contacts B56 in the socket 1 can be released from the heat dissipation grooves 4 to the outside quickly, and the socket 1 and the memory bank 55 cannot be burned out due to overheating in the matching process. As shown in fig. 1 and 3, the notch of the heat sink 4 is covered with a dust-proof net 57, and the dust-proof net 57 effectively blocks dust entering the socket 1 through the heat sink 4, thereby preventing a plurality of conductive contacts in the socket 1 from contacting badly due to covering dust for a long time.

As shown in fig. 14, 16 and 20, the outer upper end of the stopper B42 is provided with a tapered surface a44 matching with the tapered surface B47, so that the kinematic pair between the stopper B42 and the drive ring 46 is changed from high pair to low pair, and the abrasion between the tapered surface B47 and the stopper B42 on the drive ring 46 is reduced.

The insertion end of the memory bank 55, which is engaged with the two clamping bars 8 in the present invention, is wedge-shaped to engage with the inclined surfaces of the two clamping bars 8, and the conductive contact B56 on the memory bank 55 is distributed on both sides of the wedge-shaped end of the memory bank 55.

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 55 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 55 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 55 is not inserted into the socket 1, and the spring a13 for returning the two holding sticks 8 is in the compressed state; the distance between the two clamping bars 8 is slightly larger than the thickness of the tail end of the wedge-shaped end of the memory bar 55 and is smaller than the thickness of the part above the wedge-shaped end of the memory bar 55; 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 pressure mechanisms 34 are not positioned right above the card slots 2 of the socket 1, and the radian between the two pressure mechanisms 34 and the card slots 2 around the central axis of the corresponding round rod 32 is 90 degrees; the two limit blocks A31 are respectively positioned in the limit grooves 28 on the corresponding guide seats 26, and the relative positions between the two slide blocks 21 and the corresponding guide seats 26 are temporarily fixed; the spring D54 in the pressing mechanism 34 is in a compressed state, and the spring C58 in the telescopic rod 48 in the pressing mechanism 34 is in a compressed state; the spring B45 for resetting the two limit blocks B42 is in a natural state, the conical surface A44 on the two limit blocks B42 is contacted with the conical surface B47 at the lower end of the inner wall of the driving ring 46, and the insections B43 at the inner sides of the two limit blocks B42 are separated from the insections A40 on the inner rod A39 by a certain distance.

When the memory stick 55 is inserted between the two holding strips 8 in the slot 2 of the socket 1, because the two limit blocks a31 are simultaneously located in the limit grooves 28 on the inner walls of the corresponding guide seats 26, the relative positions of the two sliding blocks 21 and the corresponding guide seats 26 are simultaneously fixed, and the two sliding blocks 21 and the corresponding guide seats 26 do not 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 55 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 55 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 55 entering between them and ensure that the contact pads B56 on the memory bank 55 make good contact with the contact pads a11 on the two clamping bars 8.

After the memory stick 55 is completely inserted into the socket 1 in the initial state, the distance between the n-type pressing block 53 and the socket 1 in the two pressing mechanisms 34 is far smaller than the distance between the end surface of the exposed end of the memory stick 55 and the socket 1; then, one hand sequentially rotates the two round rods 32, the two round rods 32 respectively sequentially pass through the corresponding connecting plates 33 to drive the corresponding pressure mechanisms 34 to synchronously rotate around the central axes of the round rods 32 in the direction opposite to the clamping groove 2, and the two round rods 32 respectively sequentially pass through the corresponding rotating round blocks 30 to drive the corresponding limiting blocks A31 to gradually swing out of the limiting grooves 28 on the corresponding guide seats 26; meanwhile, the other hand presses the n-type pressing block 53 relative to the corresponding connecting plate 33 in the direction of pulling the memory bank 55 away from the socket 1, so that the distance between the n-type pressing block 53 and the socket 1 is larger than the distance between the end surface of the exposed end of the memory bank 55 and the socket 1, and the pressing mechanism 34 synchronously rotating around the central axis of the round rod 32 along with the corresponding round rod 32 is compressed in the direction of pulling the memory bank 55 away from the socket 1; in the process that the pressing mechanism 34 is compressed, the n-shaped pressing block 53 drives the inner rod a39 to retract into the telescopic sleeve a36, the n-shaped pressing block 53 drives the driving ring 46 to slide relative to the telescopic sleeve a36 in the direction that the memory stick 55 is pulled out of the socket 1 through the further compressed spring D54, the four telescopic rods 48 are compressed, the spring C58 in each telescopic rod 48 is compressed and stores energy, and the driving ring 46 is separated from the two limit blocks B42.

In the process of pressing the n-type pressing block 53 from the initial state to the direction of pulling the memory stick 55 out of 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 two connecting plates 33 mounted on the two round rods 32 from moving to the direction of pulling the memory stick 55 out of the socket 1 under the action of the compressed pressing mechanism 34 through the rack a15, the gear a18, the transmission shaft 17, the gear B19, the rack B20, the sliding block 21, the rotating round block 30 and the round rods 32, and the n-type pressing block 53 pressed in the pressing mechanism 34 only moves to the direction of pulling the memory stick 55 out of the socket 1 relative to the corresponding connecting plates 33.

When the n-type pressing block 53 in the pressing mechanism 34 reaches a position right opposite to the memory bank 55, the limiting block a31 installed on the rotating round block 30 swings out of the limiting groove 28 on the corresponding guide seat 26 completely and releases the limitation on the relative movement of the corresponding sliding block 21 and the corresponding guide seat 26; at this time, the acting force on the n-type press block 53 is removed, and under the action of the compressed spring D54 and the spring C58 in the four telescopic rods 48, the n-type press block 53 is instantly embedded with the memory bank 55 and presses the memory bank 55, and meanwhile, the driving ring 46 is close to the relative initial position of the driving ring and the limit block B42 and keeps separated from the two limit blocks B42; at this time, the spring D54 and the springs C58 in the four telescopic rods 48 are further compressed and stored with respect to their initial states by the action of the memory stick 55. The spring D54 in the pressing mechanism 34, which is further compressed and stored, and the spring C58 in the four telescopic rods 48 form a pressing action on the memory bank 55 into the socket 1 through the corresponding n-shaped pressing blocks 53, so that good contact between the memory bank 55 and the conductive contacts a11 on the two clamping bars 8 in the socket 1 is ensured.

When the minute vibration occurs, the memory stick 55 does not swing with respect to the socket 1 due to the pressing of the memory stick 55 by the two pressing mechanisms 34; when large and violent vibration occurs, the memory bank 55 is likely to swing relative to the socket 1, and the memory bank 55 swinging at this time 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 55 is inserted into the socket 1 through the corresponding rack B20; the sliding block 21 drives the pressure mechanism 34 to move towards the direction that the memory bank 55 is inserted into the socket 1 sequentially through the rotary round block 30, the round rod 32 and the connecting plate 33, and the n-type press block 53 in the pressure mechanism 34 further presses the memory bank 55, so that the memory bank 55 is inserted between the two clamping bars 8 more deeply; under the action of the spring D54, the n-type press block 53 drives the memory bar 55 to always keep good contact with the two clamping bars 8.

If the springs A13 for resetting the two gibs 8 are all failed due to damage, the memory stick 55 instantaneously bottoms under the action of the spring D54 in a compressed state; meanwhile, the compressed spring D54 in the two pressing mechanisms 34 drives the two connecting plates 33 to move towards the direction that the memory stick 55 is pulled out of the socket 1 through the corresponding driving ring 46, the compressed telescopic rod 48 and the disc 35, and the two connecting plates 33 simultaneously drive the two sliding blocks 21 to synchronously slide towards the direction that the memory stick 55 is pulled out of the socket 1 through the corresponding round rods 32 and the rotating round blocks 30; the two sliding blocks 21 are driven by the corresponding rack B20, the gear B19, the transmission shaft 17 and the gear A18 to drive the two racks A15 which are meshed with the two sliding blocks and are positioned at the same side of the holding strip 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 55 located therebetween, so that the two holding strips 8 still keep good contact with the memory bank 55 after the spring A13 completely fails, and the continuous normal use of the related electronic equipment is ensured.

When the spring D54 in the pressing mechanism 34 that continuously presses the memory stick 55 is completely disabled due to breakage, the four compressed telescopic rods 48 in the pressing mechanism 34 will drive the driving ring 46 to instantaneously surpass its initial position relative to the telescopic sleeve a36 along the direction of inserting the memory stick 55 into the socket 1 and drive the two limit blocks B42 to instantaneously cling to the inner rod a39 along the radial direction under the reset action of the internal spring C58, the insections B43 on the two limit blocks B42 instantaneously engage with the insections a40 on the inner rod a39 and prevent the relative sliding between the inner rod a39 and the telescopic sleeve a36, and the spring B45 that resets the two limit blocks B42 is compressed to store energy; the length of the pressing mechanism 34 that keeps the spring D54 completely deactivated does not change and still effectively presses the memory stick 55, thereby ensuring that the memory stick 55 can still keep good contact with the conductive contact a11 on the two clamping bars 8 under the continued pressing of the pressing mechanism 34 after the spring D54 in the pressing mechanism 34 that presses the memory stick 55 completely fails.

When the memory bank 55 is removed from the socket 1, the two pressing mechanisms 34 are sequentially operated; the operation of each pressing mechanism 34 is as follows: pressing the n-type pressing block 53 towards the direction of pulling the memory bank 55 away from the socket 1 relative to the corresponding connecting plate 33 by one hand, so that the distance between the n-type pressing block 53 and the socket 1 is larger than the distance between the end surface of the exposed end of the memory bank 55 and the socket 1, and the n-type pressing block 53 is separated from the memory bank 55; in the process that the pressing mechanism 34 is compressed, the n-shaped pressing block 53 drives the inner rod a39 to retract into the telescopic sleeve a36, the n-shaped pressing block 53 drives the driving ring 46 to slide relative to the telescopic sleeve a36 towards the direction that the memory stick 55 is pulled away from the socket 1 through the further compressed spring D54, the four telescopic rods 48 are compressed, the spring C58 in each telescopic rod 48 is compressed and stores energy, and the driving ring 46 is far away from the two limit blocks B42. Then the other hand rotates the round rod 32 to the initial state, the round rod 32 sequentially drives the corresponding pressure mechanism 34 to rotate around the central axis of the round rod 32 to the direction of the initial position synchronously through the corresponding connecting plate 33, and the round rod 32 sequentially drives the corresponding limiting block A31 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 briquetting 53 towards the direction of pulling the memory bank 55 out of the socket 1, as the two clamping bars 8 press the memory bank 55 positioned in the two clamping bars 8, the memory bank 55 prevents the two clamping bars 8 from approaching each other, so that the two clamping bars 8 prevent the connecting plate 33 arranged on the round rod 32 from moving towards the direction of pulling the memory bank 55 out of the socket 1 under the action of the compressed pressing mechanism 34 through a series of transmissions, and the pressed n-type briquetting 53 in the pressing mechanism 34 only moves towards the direction of pulling the memory bank 55 out of the socket 1 relative to the corresponding connecting plate 33.

When the pressing mechanism 34 swings to the initial position along with the round rod 32, the limiting block a31 installed on the rotary round block 30 swings into the limiting groove 28 on the corresponding guide seat 26 completely 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 press block 53 is removed, and under the action of the compressed spring D54 and the spring C58 in the four telescopic rods 48, the n-shaped press block 53, the driving ring 46, the inner rod A39 and the two limit blocks B42 are instantaneously reset relative to the telescopic sleeve A36, and simultaneously, the conical surface B47 on the driving ring 46 is in contact with the conical surfaces A44 on the two limit blocks B42 again; the spring D54 restores the initial state, the four telescopic rods 48 restore the initial state, and the spring C58 in the telescopic rods 48 restores the initial state.

Then, the memory bank 55 is removed from the socket 1.

In conclusion, the beneficial effects of the invention are as follows: the memory bank 55 inserted into the socket 1 is pressed towards the direction of inserting the memory bank into the socket 1 by the two pressing mechanisms 34 which are symmetrically distributed and in a pre-compression state, and because the spring D54 in the pressing mechanism 34 is in a state after being manually compressed when the memory bank 55 inserted into the socket 1 is pressed, the spring D54 presses the memory bank 55 to be always in close contact with the conductive contact pieces A11 on the two clamping bars 8 through the n-type pressing block 53, so that the memory bank 55 is ensured to be in good contact with the conductive contact pieces A11 in the socket 1; effectively preventing the n-type pressing block 53 from pressing the memory bank 55 with the wedge-shaped insertion end to continue to enter the socket 1 and keep close and good contact with the conductive contacts on the two clamping bars 8 under the action of the pre-compressed spring D54 when the two clamping bars slide towards the two sides of the memory bank 55 under the action of the memory bank 55 which swings due to vibration and try to be separated from the memory bank 55; meanwhile, the two clamping bars 8 sliding to the two sides drive the corresponding pressure mechanism 34 to move towards the direction of inserting the memory bank 55 into the socket 1 through a series of transmission respectively, so that the displacement difference between the pressure mechanism 34 and the memory bank 55 is reduced, the elongation of the spring D54 in the pressure mechanism 34, which is caused by the movement of the memory bank 55, in the energy release extension is effectively reduced, the pressure mechanism 34 is ensured to still have enough pressure on the memory bank 55 after the relative positions of the memory bank 55 and the two clamping bars 8 are changed due to vibration, and the memory bank 55 is always kept in good contact with the conductive contact A11 on the two clamping bars 8.

In the process of relative motion between the memory bank 55 and the two holding bars 8 due to vibration, the conductive contact piece B56 on the memory bank 55 and the conductive contact piece a11 on the two holding bars 8 rub and dislocate with each other, so that dust adsorbed on the conductive contact piece a11 and the conductive contact piece B56 due to long-term use is effectively cleaned, and good contact between the memory bank 55 and the conductive contact pieces on the two holding bars 8 is further ensured. The conductive contact a11 in the socket of the present invention is less susceptible to damage and failure due to oxidation.

Because the spring A13 for resetting the two holding strips 8 does not participate in electrical connection, the spring A13 is oxidized to a lower degree in the working process, is not easy to deform and fatigue or damage, has a better anti-vibration effect, can effectively prevent the two holding strips 8 from sliding to two sides under the action of the memory strip 55 which swings due to vibration to a certain extent, and also ensures that the conductive contact piece A11 on the two holding strips 8 keeps good contact with the memory strip 55 under the vibration condition. Even if the springs a13 for the return of the two gibs 8 all fail, in this case the two gibs 8 lose the support of the spring a 13; under the action of the spring D54 in a compressed state in the pressing mechanism 34, the memory bank 55 quickly bottoms in the socket 1, and at the same time, the energy-released spring D54 moves towards the direction in which the memory bank 55 is pulled out of the socket 1 through a series of transmission racks B20, and the rack B20 drives the two clamping bars 8 to press the memory bank 55 towards each other through a series of transmission, so that the conductive contact a11 on the two clamping bars 8 is still kept in close and good contact with the memory bank 55 under the condition that the spring a13 for resetting the two clamping bars 8 completely fails.

In addition, the present invention can still keep pressing the memory bank 55 when the spring D54 in the pressing mechanism 34 fails completely, ensuring that the memory bank 55 still has good contact with the conductive contact a11 on the two clamping bars 8 when the pressing mechanism 34 fails.
