Description

  The present invention provides a type of card connector positioning structure, in particular, a structure for guiding a memory card to an accurate insertion route, and by providing a positioning structure on the short side of the card connector, it provides axial pushing thrust and receiving force, This has the effect of preventing memory card bias.

  With the acceleration of current computer technology development, desktop computers or personal computers are also present throughout this society. In addition, the computing speed of the central processing unit is greatly improved by the progress of computer technology. For this reason, the transmission speed of computer peripheral devices must be accelerated and upgraded accordingly. On the other hand, Peripheral Component Interconnect (PCI), which is commonly used in computers at present, transmits data with other peripheral devices in a single bus bar and transmits them in order. Do. However, when the amount of transmission data is large, the processing speed of the computer system is slowed down, reducing the efficiency of the peripheral device.

  Therefore, a kind of peripheral component interconnect (PCI Express) interface has been developed. This PCI Express interface has interchangeable transmission technology and transmission technology between peer layers, and all PCI Express interfaces have independent transmission channels so that they do not depend on the conventional shared bus bar structure. For this reason, it is possible to solve the problem of speed reduction due to the sharing of the bus bar during the data transmission of the peripheral device. Then, the peripheral device is connected to the PCI Express interface provided in the computer system via the PCI Express card, and the USB 2.0 transmission channel is used. The transmission efficiency is much faster than that of the existing PCI bus bar.

  The current PCI Express card has two types of standards: Express Card with a width of 34 mm / 34 (direct entry type) and Express Card with a width of 54 mm / 54 (corner type). Normally, when connecting an express card and a connector, the connector conforms to two types of PCI express cards, so the appearance is provided with an express card / 54 (corner type) standard, and a kind of push-push structure (Push-Push structure) With the configuration, the memory card is inserted into the connector, positioned or removed by two pushing operations. However, since this type of push-push structure is usually provided on the long side of the connector, the following disadvantages arise. As an example, when the express card / 34 having a narrow width is pushed in or withdrawn from a wide insertion slot, the card is biased due to the side force of the pushing structure. Therefore, if the card is inadvertently pushed with excessive force, the memory card may be damaged. Further, when the memory card is removed, the force is concentrated on the long side of the memory card, and there is no structure for supporting the other end. The memory card is displaced from the slot groove due to the inclination, displacement, and movement inside the card connector, causing a frictional force, and the memory card cannot be withdrawn while being sandwiched inside the connector. Further, the push-in structure of the known technology narrows the internal space on the long side of the connector, so that a larger connector is required for inserting the memory card, and there remains a drawback that leads to wasted space and increased cost.

  As described above, in a normal connector, when the memory card is inserted and removed, the elasticity of the internal pushing structure is insufficient due to the elastic fatigue of the spring, and the efficiency is lowered. For this reason, some contractors have developed a structure in which a push-in structure is provided on the short side of the connector. When a memory card is mainly inserted or removed, the memory card is less displaced, and both sides can be inserted and removed while being supported by the connector side plate. However, the push-in structure provided on the short side of the connector extends the connection to form a small flat surface to prepare for the push-in of the memory card. Since the force of the spring of the push-in structure applies a force to the side surface angle to form a declination due to the reaction force of the memory card, the memory card is displaced, the frictional force increases, and the memory card cannot be removed. On the other hand, the other end away from the joint has an inclined surface with a small area and only guides the memory card, while supporting the memory card and at the same time, has no effect of assisting the pushing effect. Unless the spring force can be improved, the life of the connector is shortened. Therefore, solving the layout that rationalizes the use space inside the connector and reducing the cost is an improvement direction demanded by this industry.

  In light of the shortcomings of the above-mentioned known technologies, the inventor collected a lot of related materials, repeated evaluation and design, and invented the inventor based on years of experience accumulated by the inventor in this industry and the philosophy of continuous improvement. A card connector positioning structure was devised.

  By providing a positioning structure on the short side of the card connector and providing a push-in base that moves in response to the axial thrust of the memory card, the push-in force is concentrated at the center of the memory card by transferring the force.

Next purpose.

  By providing an inclined surface with a larger area on the guide lump and contacting the memory card, after guiding it to the appropriate insertion path, by applying both sides of the memory card to the side plate of the shielding housing, the guide part and the end surface of the push-in base, It is a further object of the present invention to provide a kind of card connector positioning structure that can reliably guide the insertion path, smooth the operation, and easily realize the insertion / extraction effect.

  The positioning structure 3 is provided at one end of the insulating table 1 and on the short side of the card connector, and repeatedly slides when the memory card 4 is pushed twice. The positioning structure 3 is provided with a base 31 and a pushing base 32, and the base 31 is attached between the insulating base 1 and the side plate 22 provided in the shielding housing 2. A support arm 312 having a guide groove 313 for positioning and sliding of the guide bar 311 is formed inside the table 31, and a pushing table 32 connected to the guide bar 311 is provided at an adjacent end of the guide bar 311, A push-in portion 321 for pushing the memory card 4 is provided at one end of the base 32, and an end of the push-in portion 321 is provided with a guide lump 322 that extends through the support arm 312 and is exposed. Further, an elastic member 33 is provided in the vertical direction between the table 31 and the pushing table 32.

  2, 3, 4, 5, and 6 are respectively a three-dimensional exploded view of the present invention, a three-dimensional external view of the positioning structure, a three-dimensional exploded view of the positioning structure, and before and after pushing in the memory card. FIG. As can be seen from the drawing, when the above-described components are combined, the positioning structure 3 is provided at one end of the insulating table 1, and then the shielding housing 2 is covered with the insulating table 1. The member 33 and the push-in base 32 are sequentially attached to the short side of the card connector, and the elastic member 33 of the positioning structure 3 forms a vertical direction inside the shielding housing 2 and is connected to the base 31 and the push-in base 32, respectively. On the other hand, the base 31 of the positioning structure 3 is provided between the insulating base 1 and the side plate 22 of the shielding housing 2, and the push base 32 is supported adjacent to the guide rod 311 of the base 31. The push portion 321 of the push base 32 is shielded. The guide lump 322 provided at the receiving space 23 of the housing 2 and extending to the outside of the support arm 312 is completed to complete the assembly of the components of the present invention.

  When inserting and using the memory card 4 in the card connector positioning structure of the present invention, when the direct insertion type memory card 4 is pushed into the receiving space 23 of the shielding housing 2, the guiding portion 211 allows the memory card 4 of various standards and dimensions. When the memory card 4 having a narrow width is used, the end surface of the guiding portion 211 is supported with the end surface of the adjacent memory card 4 and pushed into the joint connection portion 12 of the insulating table 1. When the memory card 4 is pushed in (FIG. 7), it first hits the guiding block 322 of the pushing table 32, so that the memory card 4 is guided to the accommodation space 23 and is electrically connected to the contact portion 131 of the conductive terminal set 13. The guide lump 322 is extended to the outside of the support arm 312, and an inclined surface 323 having a large area is provided and guided in the correct direction by contact with the memory card 4. Subsequently, both sides of the memory card 4 are supported by the side plate 22 of the shielding housing 2, the guide portion 211, and the end face of the guide block 322 of the push-in base 32, and the contacts of the memory card 4 and the contact portion 131 of the conductive terminal set 13 are electrically connected. Conduct. On the other hand, the memory card 4 is guided and guided to the correct route, and the guiding effect is surely exhibited, the bias when the push-in base 32 is pushed in is reduced, and the sliding movement of the push-in base 32 is performed more smoothly. The guide rod 311 is prevented from being deformed by an excessive force applied to the pushing portion 321.

  Subsequently, the push-in base 32 transmits the guide bar 311, slides the guide groove 313 provided in the support arm 312 of the base 31 inward, and the memory card 4 is pushed into a predetermined position (FIG. 8). In addition to positioning the rod 311 in the guide groove 313, the elastic member 33 is in a compressed state, and contacts the contact of the memory card 4 and the contact portion 131 of the conductive terminal set 13 to form electrical conduction. Thereby, the data of the memory card 4 is transmitted to the computer main unit via the predetermined electric circuit board connected to the connecting portion 132 at the other end of the conductive terminal set 13.

  When the memory card 4 is withdrawn, the memory card 4 is pushed again to slide the guide rod 311 in the positioning state, and the pushing portion 321 of the pushing table 32 transmits the memory card 4 by the elastic restoring force of the elastic member 33. Then, the insulation board 1 is moved outside. Therefore, the positioning structure 3 of the present invention repeatedly slides and positions the guide bar 311 in the guide groove 313 by pushing the memory card 4 twice. For this reason, when the direct insertion type memory card 4 is pushed in, the periphery of the memory card 4 is supported along the side plate 22 of the shielding housing 2 by the support of the guiding portion 211 of the shielding housing 2 and the end surface of the pushing portion 321 provided in the positioning structure 3. Advance (ie, move along the long side of the card connector). Due to the displacement of the direct insertion type memory card 4, it is turned to a wide insertion slot, and the memory card can be prevented from being damaged due to the bias.

  When used in the corner type memory card 4 (FIG. 9), the end surface of the guide block 322 provided on the push-in base 32 is supported with the joint connection surface of the adjacent memory card 4, and the push-in portion 321 is placed in front of the memory card 4. Support on the end face. With this structure, the push-in table 32 is advanced in the direction of the table 31 inside the accommodation space 23. The pusher base 32 presses the elastic member 33 through the pusher base 32 by the double presser (the guiding block 322 and the pusher 321) of the memory card 4 and moves the pusher base 32 to the support arm 312 of the base 31. . The front end face of the guide block 322 is coplanar with the end face of the support arm 312, and is supported by the memory card 4 and pushed into the joint connection portion 12 of the insulating table 1. A data transmission process can be performed after inserting and positioning the memory card 4 while holding the guiding portion 211 in the wide rear portion of the memory card 4. On the other hand, when the memory card is withdrawn, the memory card 4 is pushed again, and the push-in table 32 is pushed by the reaction force of the elastic member 33, and the push-in portion 321 and the guide block 322 are double-pressed to accommodate the memory card 4. 23 Extrude outside. Since the positioning structure 3 is provided inside the accommodation space 23, the memory card 4 can receive the pushing force amount of all the pushing tables 32. Furthermore, the elastic restoring force of the elastic member 33 prevents the frictional force when the memory card is moved out of position due to the side, and the memory card 4 can be removed from the connector by effectively using the elasticity.

  By setting the elastic restoring force of the elastic member 33 of the present invention to 1200 grams, the elastic fatigue of the elastic member 33 is extended, and the insertion / extraction of the memory card 4 can be correctly ejected from the accommodation space 23 even after the elapse of time. The life of the positioning structure of the inventive card connector can be extended. The elastic member 33 according to the present invention retracts the memory card 4 from the connector by the elasticity of the vertical transfer of force with the memory card 4. By preventing the memory card 4 from shifting, the friction of the support point is reduced. Such modifications and equivalent changes are still within the scope of the claims of the present invention.

3. In the present invention, the guiding block 322 is provided with an inclined surface 323 having a larger area so as to be guided to an appropriate insertion path after contacting the memory card 4, and the both sides of the memory card 4 are arranged on the side plate 22 of the shielding housing 2, the guiding portion 211, and the like. By touching each end face of the push-in base 321, the insertion path is reliably guided, the operation becomes smooth, and the insertion / extraction effect can be easily realized.

  A feature of the present invention is that the base 31 and the support arm 312 of the positioning structure 3 are positioned in the receiving space 23 of the shielding housing 2 and the short side of the card connector, and a pushing portion for pushing the memory card 4 into one end of the pushing base 32. 321 is provided and extended outside the support arm 312 at the other end away from the push-in portion 321 to provide a guide mass 322. In addition to the effect of guiding the memory card 4 to the correct path, the guide lump 322 effectively transfers force when the memory card 4 is pushed in, and compresses the elastic member 33 by pushing the predetermined memory card 4 in the axial direction. In addition, the pushing portion 321 and the guide lump 322 press the elastic member 33 by the double pressing of the memory card 4.
