(For example, see “Patent Document 1”)
JP 11-185904 A

  The problem to be solved by the present invention is that, for example, when the cover body is slid from the lock position to the open / close position in order to take out the card from the card connector, if the cover body is forcibly opened, the support shaft 100 is fitted. In the long groove 103 of the mating groove 101, it rotates and bites, and the support shaft 100 and the fitting groove portion of the body are overloaded and deformed and damaged. Further, even when the support shaft 100 is positioned in the circular groove 102 in the fitting groove 101, the cover body may be detached from the body due to the twisting only by applying a relatively small external force to the cover body.

In order to solve the above-mentioned problems, the present invention has a rectangular plate-shaped bottom plate and left and right side walls raised from the left and right side edges of the bottom plate, and an open top body that can accommodate a card between the left and right side walls. A rectangular plate-shaped top plate, left and right side plates hanging from the left and right side edges of the top plate, and left and right arm portions extending rearward from one end of the left and right side plates, the left and right side plates and the left and right arm portions, And a cover body that covers the open upper surface of the body with the top plate and forms a flat rectangular parallelepiped connector case with the body. Left and right fitting grooves are provided on the outer surface of the rear end portion as an overlapping portion with the left and right arm portions on the side wall, and the cover body protrudes from the left and right arm portions toward the left and right side walls to the left and right fitting grooves. Left and right support to be fitted The left and right fitting grooves have a circular groove provided at the rear end portion of the left and right fitting grooves and a long groove extending in the front-rear direction extending in the front direction by connecting the circular groove to the rear end. The vertical width of the long groove is smaller than the diameter of the circular groove, and the left and right support shafts have a cross section in which the long axis is horizontal when the cover body is fitted to the body. The outer shape is an oblong flat shaft, the width of the major axis is smaller than the diameter of the circular groove, and the thickness of the minor axis is smaller than the vertical width of the long groove. The circular groove of the fitting groove allows the left and right support shafts to rotate, the long groove of the left and right fitting groove restricts the rotation of the support shaft and allows the back and forth movement, and the left and right fitting grooves and the left and right back and forth in a state where the cover member open and closed to the body via a support shaft In the card connector mounted to be movable in the direction, the upper edges of the longitudinal groove in the fitting groove is horizontally formed, a lower edge, said as to enlarge the distance between the upper edge toward the circular groove downlink By making it inclined and making the support shaft move freely from the long groove of the fitting groove to the circular groove (so as to let it escape), it is difficult to overload the support shaft and the fitting groove.

In the present invention, combined into the body made of a resin material provided with the right and left fitting groove, in the case of providing the left and right support shafts to the cover body made of a metal plate, the body, connector closed the cover body It is desirable to partially fill the upper part of the left and right fitting grooves within the height. Further, the right and left support shaft is preferably integrally formed with the cover body by burring or drawing.

  Adopting the above configuration, increasing the thickness of the upper part of the mating groove of the body up to the height of the card connector with the cover closed, and increasing the straight part of the spindle to increase the strength of the body itself It is possible to increase the contact area between the body and the cover by the fitting groove and the support shaft. Therefore, when the support shaft is located in the circular groove in the fitting groove, it is possible to increase the strength against the vertical load that pulls the cover body upward. Further, since the contact area between the cover body and the body is increased even with respect to the lateral load in the left-right direction, the strength can be increased against the bending moment. Therefore, the strength against external force (vertical load or side load) applied to the cover body can be increased without increasing the height and width of the card connector itself. That is, it is possible to increase the strength against the twisting of the cover body.

  According to the present invention, in a card connector in which a cover body is attached to a body having an open upper surface capable of accommodating a card so that the cover body can be opened and closed and moved in the front-rear direction, the support shaft and fitting can be performed by forcibly opening and closing the cover body. It is possible to obtain a cover body mounting structure having a high fitting force that can prevent deformation and breakage of the groove portion and can securely hold the cover body against the twisting.

The other end of the contact 7 is exposed flush with the lower surface (bottom surface of the card connector) of the bottom plate 3 so that it can be soldered to a conductor of a substrate (not shown). In addition, although the contact 7 is shown integrally attached to the bottom plate 3 by outsert after the body 1 is molded, it may be integrally attached to the bottom plate 3 by insert molding. On the other hand, the cover body 2 includes a rectangular plate-shaped top plate 8, left and right side plates 9 hanging from the left and right side edges of the top plate 8, and left and right arm portions extending continuously rearward from the rear ends of the left and right side plates 9. 10, the front and rear side surfaces and the lower surface are opened, the left and right side plates 9 and the left and right arm portions 10 are overlapped with the outer side surfaces of the left and right side walls 4 of the body 1, and the open upper surface of the body 1 is covered by the top plate 8. The cover 1 is formed so as to be able to be fitted to the body 1 from above so as to constitute the flat rectangular parallelepiped connector case 11 shown in FIG.

  The body 1 is provided with left and right fitting grooves 12 on the outer surfaces of the rear end portions of the left and right side walls 4. The left and right fitting grooves 12 include a circular groove 13 provided at the rear end portion, a long groove 14 extending in the front-rear direction extending from the circular groove 13 continuously to the rear end, and a downward direction from the circular groove 13. It has an introduction groove 15 that extends and has a constant width that opens the lower end to the lower surface of the bottom plate 3. The width dimension (maximum width dimension) of the long groove 14 and the width dimension of the introduction groove 15 are smaller than the diameter of the circular groove 13. On the other hand, the cover body 2 has a flat left and right support that has an oval cross-sectional outer shape when viewed in the axial direction when the cover body 2 is fitted to the body 1 at the center of the distal end of the left and right arm section 10. The shaft 12 is provided integrally. The left and right support shafts 16 have a width dimension slightly smaller than the diameter of the circular groove 13, and a thickness dimension slightly smaller than the width dimension (minimum width dimension) of the long groove 14 and the width dimension of the introduction groove 15.

  The body 1 is provided with left and right lock grooves 17 on the outer surface of the middle part of the left and right side walls 4. The left and right lock grooves 17 have an upper end opened to the upper surface of the left and right side walls 4 and a lower end opened to the lower surface of the bottom plate 3. It has an engaging groove 19 in the front-rear direction that extends and opens the lower surface to the lower surface of the bottom plate 3. On the other hand, the cover body 2 is integrally provided with left and right engagement pieces 20 that extend horizontally inward from the lower end edges of the front and rear intermediate portions of the left and right side plates 9. The left and right engagement pieces 20 have a width dimension smaller than the width dimension of the introduction groove 18 and a thickness dimension smaller than the width dimension of the engagement groove 19.

  Furthermore, the body 1 has a total of four locations on the left and right side walls 4 including a front outer surface between the front end and the left and right lock grooves 17 and a rear outer surface between the left and right lock grooves 17 and the left and right fitting grooves 12. An L-shaped fixed terminal 21 made of a thin metal plate is fixedly attached to one piece. The other piece of the fixed terminal 21 protrudes outward from the lower ends of the left and right side walls 4 so as to be flush with the lower surface of the bottom plate 3 so as to be solderable to the conductor of the substrate. The upper end of the fixed terminal 21 is substantially flush with the upper surfaces of the left and right side walls 4. In addition, although the fixed terminal 21 is illustrated as being integrally attached to the left and right side walls 4 by outsert after the body 1 is molded, it may be integrally attached to the left and right side walls 4 by insert molding as in the case of the contact 7. . On the other hand, the cover body 2 is provided with elongate left and right leaf springs 22 that are formed in a substantially upside down “he” shape by partially cutting the front left and right sides of the top plate 8. The left and right leaf springs 22 elastically come into contact with the upper ends of the left and right fixed terminals 21 on the front side when one end (free end) of the mountain is fitted to the body 1. ing.

  The cover body 2 is held in a substantially vertical posture on the rear end side of the body 1, the left and right support shafts 16 are vertically long (vertical posture), and are positioned substantially directly below the lower end opening of the introduction groove 15. By pulling up the cover body 2 almost directly above, the left and right support shafts 16 can be fitted into the circular grooves 13 at the rear end portions of the left and right fitting grooves 12 via the introduction grooves 15. The cover body 2 can be attached to the body 1. That is, the card connector can be assembled. When the left and right support shafts 16 are fitted into the left and right fitting grooves 12, it can be easily performed without applying a load to the left and right support shafts 16 and the left and right fitting grooves 12 of the body 1 through the introduction grooves 15. Therefore, the left and right support shafts 16 and the left and right fitting grooves 12 of the body 1 can be prevented from being deformed and damaged when the card connector is assembled, and the card connector has a high height while preventing the occurrence of defective products such as malfunction of the cover body 2. Productivity can be obtained.

  The card connector assembled as described above is surface-mounted on a substrate of an electronic device such as a cellular phone, for example, and is soldered and fixed to the other end of each contact 7 or a corresponding conductor of the substrate, so as to be electrically And the lower end of each fixed terminal 21 is fixed by soldering to the substrate. The front left and right fixed terminals 21 are soldered and fixed to the corresponding conductors of the board, and are electrically connected and grounded, in order to use them as earth terminals for countermeasures against static electricity. Further, by this mounting, the lower end opening of the introduction groove 15 is closed by the substrate, the left and right support shafts 16 are prevented from being removed from the left and right fitting grooves 12, and the card connector can be held in an assembled state.

  In the card connector assembled as described above, when the left and right support shafts 16 are positioned in the circular grooves 13 at the rear end portions of the left and right fitting grooves 12, the movement of the left and right support shafts 16 is restricted and allowed to rotate. In this state, the cover body 2 can be opened and closed with respect to the body 1 using the left and right support shafts 16 as fulcrums. As a result, the cover body 2 can be opened from the closed state in which the cover body 2 is fitted to the body 1 and the upper surface of the body 1 is closed to the open state in which the cover 1 rises in a substantially vertical posture on the rear end side. When the upper surface of the body 1 is opened. Conversely, it can be closed from the open state to the closed state, and at this time, the upper surface of the body 1 is closed. When the cover body 2 is closed, the left and right support shafts 16 can be fitted into the long grooves 14 of the left and right fitting grooves 12 in a horizontal posture, and the long grooves 14 restrict the rotation of the left and right support shafts 16. In order to allow movement in the front-rear direction, the cover body 2 has the left and right support shafts 16 moved from the open / close position (unlock position) where the left and right support shafts 16 are located in the circular grooves 13 at the rear end portions of the left and right fitting grooves 12. The left and right fitting grooves 12 can be slid forward toward a lock position located in the long groove 14 at the front end portion. Conversely, it can be slid backward from the lock position to the open / close position.

  Further, as the cover body 2 is opened and closed, the introduction groove 18 of the left and right lock grooves 17 is positioned on the left and right side walls 4 of the body 1 where the left and right engagement pieces 20 interfere with each other. The cover body 2 can be opened and closed without interfering with the left and right side walls 4. The left and right engaging pieces 20 are inserted from the open upper end to the lower end of the introduction groove 18 in accordance with the closing movement of the cover body 2 at the open / close position, and the cover body 2 slides from the open / close position to the lock position. Accordingly, the left and right lock grooves 17 are inserted into the engagement grooves 19. Thereby, the opening of the cover body 2 is restricted at the lock position, and the cover body 2 is fixed and locked in a closed state with respect to the body 1. The lock can be released (unlocked) by sliding the cover body 2 from the lock position to the open / close position and returning the left and right engagement pieces 20 from the engagement groove 19 into the introduction groove 18.

  Furthermore, when the cover body 2 is closed, one end of the mountain shape of the left and right leaf springs 22 elastically contacts the upper ends of the front left and right fixed terminals 21 with the elastic displacement of the left and right leaf springs 22 from above. The cover body 2 is electrically connected to the front left and right fixed terminals (earth terminals) 21 and is grounded. Thereby, destruction of the electronic component (electrostatic breakdown) due to external static electricity is prevented. When the cover body 2 is closed, a biasing force in the direction of opening the cover body 2 is applied to the cover body 2 as a contact reaction force of the left and right leaf springs 22 with respect to the left and right fixed terminals 21 on the front side. The left and right engagement pieces 20 inserted into the engagement grooves 19 are pressed against the upper side surfaces of the engagement grooves 19 in the left and right side walls 4 of the body 1 from below, and hold the cover body 2 in a locked state.

  1 and FIG. 2, the cover in the locked position is used to attach the card 5 to the card connector in the unused state in which the cover body 2 is locked in a closed state with respect to the body 1. The body 2 is slid rearward and moved to the open / close position, the left and right support shafts 16 are positioned in the circular grooves 13 at the rear end portions of the left and right fitting grooves 12, and the left and right engagement pieces 20 are introduced into the right and left lock grooves 17. 18, the cover body 2 is opened with the left and right support shafts 16 as fulcrums in the unlocked state, and is opened in the open state as shown in the phantom lines in FIGS. 3 and 4. The upper surface of the body 1 is opened, and the card 5 is accommodated between the open upper surface and the left and right side walls 4 of the body 1. After that, the cover body 2 in the open / closed position is closed with the left and right support shafts 16 as fulcrums, and the card 5 is pushed down by the cover body 2 and closed in the closed state, and the upper surface of the body 1 is closed. In this state, the cover body 2 in the open / close position is slid forward to move to the lock position, the left and right support shafts 16 are positioned in the long grooves 14 at the front end portions of the left and right fitting grooves 12, and the left and right engagement pieces 20 are moved to the left and right. It can be performed by being positioned in the engagement groove 19 of the lock groove 17 and locking the cover body 2 in a closed state with respect to the body 1. As described above, the card 5 attached to the card connector 5 is accommodated and held between the left and right side walls 4 of the body 1 while being sandwiched between the bottom plate 3 of the body 1 and the top plate 8 of the cover body 2. The electrode 6 of the card 5 is held in contact with one end of the mountain of the contact 7 corresponding thereto. As a result, the card 5 and the substrate are electrically connected through the contact 7 so that signals and data can be input / output between them. The removal of the card 5 from the card connector can also be performed by the same operation as that for mounting the card 5 on the card connector in the unused state. Here, in the cover body 2 in a closed state of the card connector to which the card 5 is attached, in addition to the contact pressure between the front left and right fixed terminals 21 and the left and right leaf springs 22 in the opening direction, the electrode of the card 5 A contact pressure between the contact 6 and the contact 7 is applied via the card 5.

  Next, a flat left and right support shaft 16 provided on the left and right sides of the rear end side of the cover body 2 and the rear end of the body 1 on the body 1 having an open top surface capable of accommodating the card 5 as described above. The left and right fitting grooves 12 are provided on both the left and right sides of the side to fit the left and right support shafts 16. The circular grooves 13 allow the left and right support shafts 16 to rotate, and the circular grooves 13 are connected to the rear end. A card connector that extends in the front-rear direction and is attached to be movable in the front-rear direction in a closed state that can be opened and closed via a left-right fitting groove 12 having a long groove 14 that restricts the rotation of the left-right support shaft 16 and allows front-rear movement. In the following, the mounting structure of the cover body 2, that is, the characteristic configuration of the left and right fitting grooves 12 of the body 1 and the left and right support shafts 16 of the cover body 2 will be described with reference to FIGS. Since the fitting groove 12 and the support shaft 16 have the same structure on the left and right, only the right fitting groove 12 and the support shaft 16 are shown in FIGS.

  First, as shown in FIGS. 5, 6, and 7 (A), the upper edge 14 a of the long groove 14 in the fitting groove 12 is formed horizontally, while the lower edge 14 a is directed toward the circular groove 13. It forms in the downward inclination which enlarges the space | interval (width dimension) with the upper edge 14b. As a comparative example for this configuration, FIG. 7B shows a long-width groove 14 ′ having a constant width in which the lower edge 14 a ′ is not formed in a downward slope. For example, when the cover body 2 is slid from the lock position to the open / close position in order to take out the card 5 from the card connector, if the cover body 2 is forcibly opened, the lower side shown in FIG. In the long groove 14 ′ having a constant width in which the edge 14 a ′ is not formed to be inclined downward, the support shaft 16 rotates and bites in the long groove 14 ′ in the fitting groove 12, and the support shaft 16 and the body 1 are fitted. In the long groove 14 in which the lower edge 14a shown in FIGS. 5, 6, and 7A is formed in a downward slope as shown in FIGS. Using the force in reverse, the support shaft 16 is always moved to the circular groove 13 along the inclination of the lower edge 14a of the long groove 14 (because it is released), so that it is caught in the long groove 14. Without overloading the support shaft 16 or the fitting groove 12 of the body 1 It becomes strange. Therefore, the deformation | transformation damage of the support shaft 16 and the fitting groove 12 part of the body 1 by the forced opening and closing of the cover body 2 can be prevented.

  Second, as shown in FIGS. 5, 6, 7 (A), and 9 (A), a cover is formed on the upper surface of the rear end portion of the side wall 4 of the body 1, which is the upper portion of the fitting groove 12 of the body 1. In the height of the card connector in a state in which the body 2 is closed, the padding is partially applied. Thirdly, as shown in FIGS. 8 (A) and 9 (A), the support shaft 16 is formed by a burring process in which a pilot hole 24 is formed in the flat arm portion 10 and vertically rises into a long cylindrical shape. is doing. As a comparative example for this configuration, FIGS. 7 (B) and 9 (B) show a body 1 ′ in which the upper portion of the fitting groove 12 is not overlaid, and FIGS. 8 (B) and 9 (B). The support shaft 16 ′ formed by overhanging is shown in FIG.

  In the body 1 ′ where the upper portion of the fitting groove 12 shown in FIGS. 7B and 9B is not overlaid, the thickness T2 of the upper portion of the fitting groove 12 of the body 1 ′ is the thickness of the body 1 ′. In the body 1 which is thin up to the upper surface of the side wall 4 where no embossing is applied, and which is overlaid on the upper part of the fitting groove 12 shown in FIGS. 5, 6, 7 (A) and 9 (A). The thickness T1 of the upper portion of the fitting groove 12 of the body 1 is increased by the thickness T2 because the thickness of the build-up portion 23 is added to the thickness T2, so that the strength of the body 1 itself can be increased. Further, in the support shaft 16 ′ formed by the overhang processing shown in FIGS. 8B and 9B, the roundness R1 ′ of the tip shoulder portion of the support shaft 16 ′ becomes larger than the plate thickness dimension. The ratio of the length S ′ of the straight portion between the roundness R1 ′ of the tip shoulder portion and the roundness R2 ′ of the rising portion from the arm portion 10 to the total shaft length is small, as shown in FIGS. 8A and 9A. In the support shaft 16 formed by burring, the roundness R1 of the tip shoulder portion of the support shaft 16 can be made smaller than the thickness of the plate. The roundness R1 of the tip shoulder portion and the rising portion from the arm portion 10 can be reduced. The ratio of the length S of the straight portion between the roundness R2 to the shaft total length can be increased and increased, and the contact area (fitting force) of the body 1 and the cover body 2 by the fitting groove 12 and the support shaft 16 can be made the same groove. Can be increased in depth and the same axial length. With the second and third configurations, when the support shaft 16 is positioned in the circular groove 13 in the fitting groove 12, the strength can be increased with respect to the vertical load Y (see FIG. 2) that pulls the cover body 2 upward. it can. Also, with respect to the lateral load X in the left-right direction (see FIG. 4), the contact area between the cover body 2 and the body 1 is increased by the second configuration, so the bending moment M (see FIG. 4). The strength can be increased. Therefore, the strength against external force (vertical load Y and side load X) applied to the cover body 2 can be increased without increasing the height and width of the card connector itself. That is, it is possible to increase the strength against the twisting of the cover body 2. Therefore, it is possible to obtain a cover body mounting structure having a high fitting force that can securely hold the cover body 2 against the body 1 against the twisting. Note that the same effect can be obtained even if the support shaft 16 is formed by drawing instead of burring.

  As mentioned above, although this Embodiment showed an example of the suitable embodiment of this invention, this invention is not limited to it, Various modifications can be implemented within the range which does not deviate from the summary.

  For example, in the present embodiment, the body 1 is provided with the fitting groove 12 and the cover body 2 is provided with the support shaft 16. Conversely, the body 1 is provided with the support shaft 16 and the cover body 2 is provided with the fitting groove 12. In this case, deformation damage to the support shaft 16 on the body 1 side and the fitting groove 12 on the cover body 2 side due to the forced opening and closing of the cover body 2 can be prevented.
