The _ sub-1 Shield has a side wall and a holding portion below the side wall for fixing the memory card connector to the electronic device. When the corresponding memory card is inserted into the memory card (4) (4), the data transmission is performed by the gamma _ _ sub-subscriber to allow the signal to pass, thereby electrically connecting the memory card to the conductive terminal. Wherein, the pair of switches and the sub-and a fixed terminal 'each-switch terminal include a pin portion and a conductive contact for mating contact. Wherein the 岐 terminal is integrally formed by the sidewall of the shielding case and the retaining portion of the side wall serves as a pin portion of the fixed terminal. When the memory card is inserted into the inside of the connector, the memory card-side brittle terminal abuts, so that the terminal is moved to the outer side 5 M331802 and contacts the fixed terminal, thereby realizing the detection function of the memory card insertion. However, the conventional memory card connector has the following drawbacks: D uses the inserted memory card itself (such as the card housing) to press the elastic terminal of the switch terminal to make electrical contact with the fixed terminal, and repeatedly makes the hidden card itself. Easy to wear', thus affecting the stable contact between the elastic terminal and the fixed terminal; 2) The direct pressure contact of the inserted card by the elastic terminal alone can generate a force, and if the operation is improper, the elastic terminal is more easily deformed. Stability; 3) The memory card itself has a positive/negative tolerance during the manufacturing process. # When the memory card has a negative tolerance, the elastic terminal is less likely to reach the JL force of the foot and cannot reliably contact the fixed terminal, thereby affecting the detection of the insertion of the domain card. If the memory card has a positive tolerance, the conductive terminal material will be permanently (10)' due to excessive deformation and cannot have high reliability and durability. For the current trend of electronic devices, the defects of the above-mentioned switch terminals will become more and more obvious. For example, when the above ^ ^ W-flash ^ ^, due to the limited space of the face type memory card connector, the elastic terminal of the above structure is in the shape of the memory surface X; the brother is strict and easy to deform, thereby affecting the memory card connection Contact and use of the device (4) Therefore, it is necessary to improve the conventional memory card connection (10) mode and the extracted structure to overcome the aforementioned drawbacks. Most of the hidden card connectors of the head I use a push (four) h_push) type of card-removing mechanism to insert and unplug the card. Most of the card-removing mechanisms include: · A sliding seat is installed on the side of the insulating body σ by (1) into and out, A spring-guide rod and a semi-lock spring are mounted on the sliding seat, and the end of the half-lock spring is formed with a fitting protrusion. When the memory card is inserted, the recess provided on the side of the memory card fits well with the mating projection of the loading lock and the memory card can be held in the 6 M331802 semi-lock state. When the memory card is pushed in the half-locked state, the slide seat is moved to the forward position against the elastic force of the re-elastic. At this time, the guide rod moves along the advance trajectory of the cam groove provided on the slide seat. The guide rod is blocked by the cam lobe, and the slide base is locked in the forward position to position and fix the memory card in a readable and writable state. When the above memory card needs to be taken out, just push the memory card again. Then, the above-mentioned slide seat re-enters, and the guide rod is moved from the cam convex portion toward the forward end portion of the cam groove and is smashed. Then, if the pressing of the memory card is released, the sliding re-fixing elastic force is pushed back to the surface. The guiding rod moves along the returning track of the cam groove to the end of the returning track, and the sliding seat also moves to the retracted position. At this time, the engaging convex portion of the semi-locking elastic piece is engaged with the concave portion of the memory card from the lateral direction, and the memory card is half-locked so as not to fly out. After the sliding steel reaches the retracted position, the matching convex portion of the semi-locked elastic piece is detached from the concave portion of the memory card, so that the memory card can be dialed from the connector to the front.匕The above. The memory card connector uses a structure such as a so-called heart-shaped cam groove mechanism and a re-spinning spring to push the memory card into and out of the set position in a push/push (four) manner. The half-locked state of the memory card is not fully-locked by the matching convex portion of the semi-locked elastic piece and the concave portion of the memory card, and the memory card is easily pulled out by the loosely held state. With insertion. In the above push (4) ^ush test card retraction mechanism, the power source is heavy 疋 κ 'The spare spring yellow force will produce a large inertia when it is released instantaneously, that is, it will produce impact force, so it is in the memory cut, in the revolving spring The elastic _ under the age of having a memory card hastily flew out from the 7 M331802 connection. In addition, when the memory card moves, the semi-locking elastic piece is subjected to the anti-gamma force from the mating port U卩 of the memory card to bend the lion laterally, and since there is no mechanism for stopping the bending shape, it is impossible to perform the half in the middle of the movement. The pressure of Na tablets. If the pressure of the semi-locked shrapnel is strong, it can effectively prevent the memory card from flying out of the connector. However, in this case, if the pressing force of the semi-twisted shrapnel is too strong, the insertion and removal of the memory card may not be smoothly performed. In order to prevent the memory card from flying out, it is also possible to set the elastic force of the re-set spring weakly. However, if the above-mentioned re-established elastic force, the financial memory card cannot be used to withdraw the required resetting force (the process) from the connection port. There are also some designs in the prior art that prevent the memory card from flying away from the connector. 'But these designs usually cannot absorb the tolerance of the memory card, that is, when the memory card has a positive or negative tolerance, the anti-cards fly out. The design will fail. Further, the above conventional memory card connector is generally not provided with a detachment prevention mechanism for preventing the memory card from being detached from the connector. When the memory card is in normal use, it is in the locked function _, the memory card is not abnormally dropped by the deformation force of the semi-locked elastic piece and the county power between the memory card and the connector. However, in actual use, it can be found that the memory card is often loosened due to artificially forcibly pulled out, or the vibration or abnormal external force generated by the electronic device in the moving private state, and the memory card cannot be operated. There are also some designs in the prior art that prevent the memory card from coming out of the connector. However, these designs usually use metal parts to interact with plastic parts to achieve the function of preventing the card, but due to the plastic The strength of the component itself is insufficient, so the design of the anti-card release is easy to be invalid. Therefore, in order to ensure the safety and reliability of the memory card in the electronic device, it is necessary to design a memory card connector, which must have a memory card. After being fully inserted, it can effectively prevent the vibration of the 8 M331802 due to the electronic loading surface and the detachment of the original card caused by the abnormal drop and the connector is easy to operate, and has a simple mechanism and easy to produce raw silk. advantage. [New content] The main purpose of the present invention is to provide a memory card connector with a _ terminal, and the side end of the fiber-readable person of the switch end, which has a fine transfer contact and a long service life. Another object of the present invention is to provide a memory card connector having a switch terminal having a function of preventing a flying card. A further object of the present invention is to provide a memory card connector having a switch terminal having a function of preventing the inserted memory card from being released from the connector. In order to achieve the above object, the present invention provides a memory card connector, comprising: a plurality of conductive terminals for corresponding connection with a card reader; tender contact, - for elastic end, for drum extraction, for an insulating body The conductive terminals and the switch terminals are accommodated, and a card retracting mechanism is disposed on the side of the insulating body. The insulative housing is provided with a card space for accommodating a memory card, and is formed by two opposite side walls and a connecting side. The pair of elastic closing terminals includes first and second switch terminals, each of which is provided with a holding portion for securing the terminal in the connecting wall of the insulating body, and the pin portion extending from the mouth portion to the insulating portion. In vitro, and a miscellaneous portion extends inwardly from the retaining portion to form a free end of the structure, and the free end is provided with a conductive contact. The elastic portions of the pair of latching switch terminals are always spaced apart by a distance. The card ejecting mechanism is disposed on the sidewall of the & body, and has a metal contact to correspond to the terminal. When the memory card is inserted into the insulative body of the memory+connector, the card recalls the card to drive the card-removing mechanism along the card 9 M331802'° toward the S-seed scales, and the straight ship Kalin contacts the storage person. Elastic switch-: between the springs (four) of the mountain, the elastic parts of the two elastic switch terminals are elastically generated by the buckling, and the contact piece is clamped between the two elastic parts, and the two conductive joints with the elastic parts The points are respectively docked, so that the two elastic switch terminals are electrically turned on, that is, the function of the memory card insertion is achieved. The two conductive contacts of the above-mentioned δ hai to the elastic switch terminals are arranged offset along the insertion and removal direction of the memory card, so that the contacts of the card ejecting mechanism can be docked with the two conductive contacts of the two switch terminals. More stable detection. Compared with the prior art, the memory card connector according to the present invention utilizes the metal contact member which is not easy to be learned on the card ejecting mechanism, and the elasticity provided by the two elastic portions of the pair of closing terminals can effectively "the temple and the tight And the electrical contact with the contact member is stable, so that the function of the picking function can be ensured. At the same time, the resistance of the conventional plug connector can be overcome by using the resistance of the green plug-in memory card. The single-elastic terminal accommodates the defect of permanent deformation of the new button, thereby improving the reliability and durability of the switch terminal and the memory card connector. • 3 'For the above purpose, the card card mechanism of the new type of memory card is further advanced. The method includes: a / month moving seat can slide along the insertion direction of the memory card on the insulating body, a resilient member provides a return elastic force to the sliding seat along the exit direction of the memory card, and a half lock elastic piece is mounted on the sliding seat and has a matching convex portion, the matching convex portion of the semi-locking elastic piece protrudes into the card space of the insulating body, and cooperates with the concave portion provided on the side of the reading card to ensure that the domain card is in a semi-locked state. Body set - The elastic piece has a corresponding half piece, and the blocking elastic piece has a base protruding downward from the shielding body, and the elastic part extends from the base in the exit direction of the memory card. When the memory card is to be withdrawn, the blocking elastic piece The elastic portion abuts the semi-locking elastic piece to apply the M331802' f to the semi-locking elastic piece, thereby reducing or even canceling the impact force of the return elastic element, and not only suppressing the -phase deformation of the semi-locked elastic piece but also increasing the half The mating force of the locking protrusion of the locking elastic piece and the concave portion of the memory card, and the blocking elastic design can allow the memory card to have a dimensional tolerance, that is, when the size of the memory card includes positive and negative tolerances, the blocking convex piece and the semi-locking elastic piece cooperate with each other. The portions can be pressed against each other in a direction away from or toward the memory card to allow the tolerances. Therefore, when the card is withdrawn from the memory card, the fiber card connector according to the present invention can effectively prevent the problem of the domain card carrier. In addition, in order to achieve the above object, the semi-locking elastic piece which is reset according to the card-removing mechanism of the memory card connector of the present invention is further provided with a protruding portion, and the shielding housing is provided with a resilient piece. a protruding portion. When the memory card is fully inserted and in the pinning (four) state, the _= downwardly projecting abutting portion can be pressed against the protruding portion of the semi-locking elastic piece to extend, thereby changing the biasing force arm of the semi-locking elastic piece, thereby Correspondingly, the holding force of the semi-locking elastic piece is increased to prevent the convex portion 2 from the concave portion of the memory card. This ensures that the inserted memory card does not accidentally fall off during normal use or when it is swept or abnormally dropped. To ensure the safe and reliable use of the memory card, and to prevent the memory card from being forcibly pulled out to a certain extent. At the same time, the cooperation between the abutting portion of the shielding shell and the protruding portion of the semi-locking elastic piece is metal and metal. The cooperation is not easy to fail because the memory card is in working condition, even if the memory card according to the present invention is still effective, the needle is accidentally detached due to vibration and abnormal cake force.

Lock status. However, in this half-lock state, the power on the TF card 9 is still connected to the second contact portion 32 of the two terminals 3 to achieve an electrical connection, and the relative elastic portion of the __7 is between _, also _ silk, _, and the electrical connection between the memory is still in the initial 〇pen (open circuit) state. Connecting the door: As shown in Figs. 1 and 1G, (4) the card 9 continues to be inserted into the connector in the A direction, and the Γ:: slides forward to reach the foremost end of the insertion direction, and the elastic member 42. The odor is removed, and the sliding seat 41 is retracted, and the guiding process 4 # 43 cooperates with the cam groove and the closing portion to stop moving in the insulation. At this time, as shown in the first and eighth figures, (4) the contact and the chic 91: the first of the object: the shaft 41 妾 at this time, the contact member 45 assembled on the sliding seat 41 moves with the sliding seat Until the contact member 45 is inserted along the slope of the free end 72〇16 M331802 of the elastic portion of the two switch terminals 7, so that the elastic portion 72 of the two elastic switch terminals 7 generates a repulsive force due to the pressure, the contact member 45 is pressed. Between the elastic portions 72 of the two switch terminals 7 and the two conductive contacts 721 of the free ends 720 of the two elastic portions 72 respectively, the two elastic switch terminals 7 are electrically connected to each other, thereby achieving memory card insertion. Detection function. Thus, it can be determined that the card 9 has been stably connected to the connector, so that it enters the active state of writing, and the TF card 9 is electrically connected to the circuit board of the electronic device through the memory card connector. As described above, the memory card connector of the present invention is in contact with the two elastic portions 72 of the switch terminal 7 by the non-wearing metal contact 45 provided on the sliding base 4, so that electrical contact between the two can be made. It is more compact and stable, so it can ensure that the detection function is correct. At the same time, it is also possible to overcome the problem that the conventional switch editor only suffers from metal fatigue and permanent deformation when the terminal is bent and is in contact with the other terminal, especially in the case where the memory card itself has a constant dimensional tolerance, thereby improving the switch terminal. 7 and the reliability and durability of the memory card connector. In addition, preferably, the two conductive contacts 721 disposed on the free ends 720 of the two elastic portions 72 of the switch terminal 7 are offset along the insertion and removal direction μ of the TF card 9, such that the contact member 45 of the card ejection mechanism 4 The electrical connection can be achieved twice with the pair of switch terminals 7, so that a more stable and reliable detection function can be provided. As described above, in the conventional design, the Leica 9 is only elastically deformed by the deformation elastic force of the half lock elastic piece 44 (i.e., the fitting convex portion 441 of the half lock elastic piece 44 is elastically fitted with the concave portion 90 of the TF card 9) and the τρ card 9 The friction between the connector and the connector ensures that the TF card 9 does not fall off abnormally, which is slightly weak. From the actual financial situation, the TF card 9 is often pulled out by the artificial force, or the vibration generated during the movement, abnormally falling out of the connector, loosening and falling off, causing the card to be opened. 9 is not working properly. On the other hand, as shown in the figure u1, when the tf card 9 is in the locked state, the side of the second shielding case 6 of the present type of memory card connector is used. Pressing the side of the protruding portion 442 of the semi-locking elastic piece 44 can enlarge the force arm of the semi-locking elastic piece ,, thereby correspondingly increasing the holding force of the half-locking elastic piece 44 to the concave portion 9 TF of the TF card 9, and preventing the engaging convex portion 441 from the 犴 card The recess 90 of 9 is disengaged. In this way, it can be ensured that the inserted TF card 9 does not detach from the connector when it is vibrated, lost, or forced during use, so that the use of the P card 9 can be ensured at the same time, the first shielding shell The fit between the abutting member 64 of the 6 and the projections 442 of the semi-locking elastic piece 44 is a combination of a metal and a metal material, so that it has sufficient strength to be ineffective. In addition, the abutting member of the second shielding case 6 is formed by tearing, so that the structure is simple and the manufacturing is convenient. Please refer to FIG. 3, FIG. 7 and FIG. 9. When the card 9 is to be withdrawn, the card/U card direction A can be pushed, and the card 7 card 9 immediately drives the card ejection mechanism 4 to slide. The seat 4 is connected with the V-lead cup 43 to move one end of the guide rod 43 in the cam groove. When the pressing of the TF card 9 is released, the sliding member 41 is brought back to the semi-lock position by the TF card 9 because the elastic member 42 rebounds against the sliding seat _ M1 in the retracting direction b. At this time, the fitting convex portion of the half-lock elastic piece 44 is laterally fitted with the concave portion % of the TF card 9, and the mF card 9 is again held in a relaxed semi-lock state. Subsequently, when the card 9 is pulled out, the mating projection tear of the above-described half-lock tab 44 can be detached from the recess 9 of the TF card 9, thereby exiting the TF card 9. As shown in FIG. 9, in order to overcome the problem that the TF card 9 may rapidly fly out of the connector due to the return elastic force of the elastic member 42 of the card ejecting mechanism*, the memory card of the present invention is overcome. The connector is provided with a block 18 M331802 piece 63 at a position corresponding to the half-lock spring 44 of the second shielding shell 6. For example, the uranium has a resilient portion 631 extending in the exiting direction B of the TF card 9 and inclined toward the side of the semi-locked elastic piece 44. When the TF card 9 is withdrawn from the half-locked state as shown in FIG. 9, the elastic portion 631 of the blocking elastic piece 63 abuts against the free end of the fitting convex portion 441 of the half-lock elastic piece 44 and the half-locked elastic piece The fitting convex portion 441 of the 44 applies a force in the direction of the marking card 9, thereby reducing or even counteracting the impact force of the elastic member 42 during the card retracting process, suppressing the "4" bending deformation of the semi-locking elastic piece 44, and increasing the semi-locking. The holding force between the engaging convex portion 441 of the elastic piece 44 and the recessed portion 90 of the card. Thus, when the TF card 9 is taken out, the tf card 9 can be effectively prevented from flying rapidly from the second socket 14 of the insulating housing 1. Moreover, the resistance of the slamming snippet design can be the tolerance of the TF card 9, that is, when the size of the TF card 9 has a positive and negative tolerance, the elastic portion 631 of the blocking elastic piece 63 cooperates with the semi-locking elastic piece 44. The convex portions 441 can be mutually pressed against each other in a direction away from or toward the TF card 9 to absorb the tolerances. In summary, the memory card connector according to the present invention utilizes a sliding seat as compared with the prior art. The metal contact 45 on the 41 is in effective contact with the dissolving switch terminal 7, and is not easily changed. Therefore, the side function of the stable can be changed. # When the TF card 9 is completely inserted into the working state, the semi-locked elastic piece 44 can be changed by the mutual contact between the resisting member 64 and the protruding portion 442 of the half-locking elastic piece 44. The force arm increases the holding force of the half-lock spring 44 to the TF card 9, thereby ensuring that the inserted TF card 9 does not fall off due to vibration, abnormal rotation or external force during use. In addition, the TF card 9 is exited. At this time, the elastic portion 631 of the resisting elastic piece 63 of the present connector is abutted at the free end of the engaging convex portion 441 of the semi-locking elastic piece 44, and the rapid ejection of the check card $ from the connection can be effectively prevented. The above description is only a preferred embodiment of the present invention, and it is not intended to limit the scope of the novel patent protection 19 M331802, so the equivalent changes of the present specification and the drawings are included in the present specification. The scope of the new rights protection is hereby stated. [Simple description of the drawing] Fig. 1 is an exploded perspective view of the new memory card connector. Fig. 2 is a perspective assembled view of Fig. 1. Figure 3 is an exploded perspective view of another angle of the new memory card connector. Figure 4 is a three-dimensional combination of Figure 3. Fig. 5 is a perspective assembled view of the insulative housing of the novel memory card connector and the first terminal, the second terminal, and the clamping mechanism. < Fig. 6 is a perspective view of the second shield case of the novel memory card connector. Figure 7 is a schematic view of the new type of memory card connector, showing the positional relationship between the pair of switch terminals and the contacts on the card ejecting mechanism when the TF card is in a semi-locked bear (for clarity, the insulative body has a portion) resection). Figure 8 is a schematic view of the new type of memory card connector, showing the docking state between the TF card in the working state, the switch 'sub-pair and the contact on the card-removing mechanism (for clarity, the insulating body is partially cut off) ). Figure 9 is a schematic view of the new type of memory card connector, showing that the new type prevents the card from flying away when the card is removed. Figure 10 is a schematic view of the novel memory card connector showing the structure of the present invention which prevents the card from being accidentally detached when the Leica is in operation. 20 M331802 [Main component symbol description]
