  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. First, the card connector manufactured by the present invention will be described. 1 to 4 are views showing the structure of an embodiment of a card connector manufactured according to the present invention. As shown in FIGS. 1 to 4, the card connector 1 receives the card M so as to be freely inserted and removed, and electrically connects the card M and a mounting board (not shown) on which the card connector 1 is mounted.

  The arrows in FIGS. 1 to 4 indicate the insertion / extraction direction of the card M. An upward arrow indicates a direction in which the card M is removed from the card connector 1, and a downward arrow indicates a direction in which the card M is inserted into the card connector 1. In the following description, the upper side of FIGS. 1 to 4 is referred to as the rear end side of the card connector 1, and the lower side is referred to as the front end side of the card connector 1.

  The card connector 1 includes a contact 2 that is electrically connected to the card M and the mounting board, a housing 3 that insulates and holds the contact 2, a slider 4 that moves within the housing 3, a guide pin 5 that is pivotally supported by the housing 3, and a housing 3 And a coil plate 6 sandwiched between the slider 4 and the base plate 7.

  The card connector 1 includes a metal shell that covers the entire housing 3 and a metal lock piece that is disposed in the housing 3 and locks the received card M. In the present embodiment, the card connector 1 is illustrated. Is omitted.

  The contact 2 electrically connects the contact of the card M and the land of the mounting board. As shown in FIGS. 1 to 4, the contact 2 is held by the housing 3 in a state extending in the insertion / extraction direction. In the present embodiment, the contact 2 is held by the housing 3 on both the front end side and the rear end side.

  In the present embodiment, the eight contacts 2 are held by the housing 3 in a state where they are arranged at a predetermined pitch in a direction orthogonal to the insertion / extraction direction. The contacts 2 have a length of about 20 mm to 30 mm and a thickness of about 0.2 mm to 0.4 mm in the insertion / extraction direction, and are arranged at a pitch of about 1 to 4 mm. The number, dimensions, and pitch of the contacts 2 held in the housing 3 can be appropriately changed depending on the type of the card M, the layout of the land of the mounting board, and the shape thereof, and are not particularly limited.

  The contact 2 has a front end side contact 21 connected to the contact of the card M and a rear end side contact 22 connected to the land of the mounting board. The contact 2 is formed by pressing a first long metal plate 23 (described later) made of a long conductive thin metal plate such as beryllium copper, titanium copper, or phosphor bronze.

  Further, the contact 2 is subjected to base plating such as nickel plating, and the tip side contact 21 is subjected to finish plating such as gold plating as necessary. Further, the material of the contact 2 is appropriately changed in consideration of springiness, conductivity, press workability, etc., and is not particularly limited.

  The housing 3 is made of an insulating resin material such as polybutylene terephthalate (PBT), polyamide, liquid crystal polymer (LCP), or polycarbonate (PC). The housing 3 is formed by insert-molding the contact 2 using a known injection molding technique. The material of the housing 3 is appropriately changed in consideration of moldability, heat resistance, etc., and is not particularly limited.

  As shown in FIGS. 1 to 4, the housing 3 is formed with a moving groove 31 extending in the insertion / removal direction in the vicinity of the left end, a protrusion 32 on the left side of the distal end, and a pivot hole 33 on the right of the protrusion 32. . The housing 3 also holds a base plate 7 as shown in FIGS.

  The slider 4 is placed in the movement groove 31 and moves in the movement groove 31 in the insertion / removal direction as the card M is inserted / removed. As shown in FIGS. 1 to 4, the surface of the slider 4 has a circulation cam groove 41 extending in the insertion / extraction direction and having a substantially heart shape, a protrusion 42 on the left side of the cam groove 41, and a right side of the cam groove 41. A contact portion 43 is formed on the tip side.

  The protrusion 32 is inserted through one end of the coil spring 6, and the protrusion 42 is inserted through the other end of the coil spring 6. That is, the slider 4 is biased in the pulling direction by the coil spring 6. Therefore, the slider 4 before insertion of the card M is placed in the moving groove 31 with its rear end in contact with the rear end of the moving groove 31. The slider 4 is formed by molding a resin material similar to that of the housing 3 using a known injection molding technique.

  One end 51 of the guide pin 5 is pivotally supported in the pivot hole 33 and the other end 52 is inserted into the cam groove 41. That is, the guide pin 5 is placed on the housing 3 and the slider 4 so as to bridge between the housing 3 and the slider 4.

  As the slider 4 moves in the insertion direction, the guide pin 5 swings with the one end 51 as a rotating shaft and the other end 52 as a cam follower (follower) that moves in the cam groove 41. The bottom surface of the cam groove 41 is provided with an inclination, and the other end 52 moves only in the counterclockwise direction, as shown in FIGS. Moreover, the guide pin 5 is formed by press-working the 2nd metal long plate 56 mentioned later which consists of long metal thin plates, such as stainless steel.

  The coil spring 6 is formed of a known winding or the like, and the base plate 7 is formed by pressing a first metal long plate 23 described later, like the contact 2.

  Next, the operation of the card connector 1 when inserting and removing the card M will be described. As shown in FIG. 1, when the card M is inserted into the housing 3, the tip of the card M comes into contact with the contact portion 43, and the slider 4 moves in the moving groove 31 against the bias of the coil spring 6. Start moving in the insertion direction. Then, the other end 52 at the position 41 a in the cam groove 41 starts to move relative to the rear end side in the cam groove 41 as the slider 4 moves in the insertion direction.

  When almost the entire card M is received in the housing 3, as shown in FIG. 2, the tip of the slider 4 comes into contact with the housing 3, and the other end 52 moves to a position 41b in the cam groove.

  When the insertion of the card M is stopped, as shown in FIG. 3, the slider 4 is moved again in the pulling direction by the biasing force of the coil spring 6. The guide pin 5 swings and the other end 52 moves to the position 41 c in the cam groove 41.

  The other end 52 comes into contact with the wall surface of the cam groove 41 by the urging in the pulling direction by the coil spring 6, and the slider 4 is fixed. When the card M is pushed again in the insertion direction, as shown in FIG. 4, the slider 4 moves in the insertion direction, the guide pin 5 swings, and the other end 52 moves to the position 41 d in the cam groove 41. Thereby, the fixation of the slider 4 is released.

  Then, the slider 4 is urged by the coil spring 6 to start moving in the pulling direction, and the contact portion 43 pushes the card M in the pulling direction. The other end 52 returns to the position 41a in the cam groove 41, and becomes the state of FIG. As a result, the card M is unaccepted and can be taken out.

  Next, when the card connector 1 is manufactured, the contact 2, the housing 3, the slider 4, the guide pin 5, the coil spring 6, and the base plate 7 are supplied to the mold 100 according to the embodiment of the present invention. explain.

  FIG. 5 is an external view of the first plate-like member 27. The first plate-like member 27 is in the form of supplying the contact 2, the housing 3, the slider 4, the coil spring 6 and the base plate 7 to the mold 100. The first plate-like member 27 is formed on the housing 3 by pressing the first metal long plate 23 to form the contact component 29 and the base plate component 71, and then performing insert molding. 3, a slider 4 and a coil spring 6 are placed. Here, the contact component 29 and the base plate component 71 are the contact 2 and the base plate 7 before being separated from the first long metal plate 23.

  A plurality of positioning pilot holes 24 are formed at a predetermined pitch at both ends of the first long metal plate 23 extending in the longitudinal direction. In the present embodiment, the pilot holes 24 have a diameter of about 2 to 3 mm and are formed at a pitch of about 4 to 6 mm. Note that the diameter and pitch of the pilot holes 24 are not particularly limited.

  A plurality of contact parts 29 are formed on the first plate-like member 27 at a predetermined interval. The contact component 29 becomes the contact 2 by cutting the region 26 indicated by hatching in the drawing.

  The first long metal plate 23 is formed with a plurality of reinforcing joints 27a extending in the width direction connecting both ends with a predetermined interval. Further, as described above, a plurality of housings 3 are formed on the first plate-like member 27 at a predetermined pitch by performing insert molding for each of the eight contact components 29. The housing 3 is connected to the first plate-like member 27 by a connecting portion 27b.

  The slider 4 is placed in the moving groove 31 of the housing 3. Further, a coil spring 6 is sandwiched between the housing 3 and the slider 4. A plurality of base plate components 71 are formed on the first plate-like member 27 at a predetermined interval. The base plate component 71 becomes the base plate 7 by cutting the region 26 and the connecting portion 27c indicated by hatching in the drawing.

  As described above, the first plate-like member 27 includes the main body component 28 including the contact component 29, the housing 3, the slider 4, the coil spring 6, and the base plate component 71 in the longitudinal direction with an interval of, for example, about 4 to 6 mm. A plurality are formed.

  FIG. 6 is a view showing the guide pin 5. The left figure of FIG. 6 shows the left sectional view of the guide pin 5, and the right figure shows a front view. The guide pin 5 is composed of one end 51, the other end 52 and an intermediate portion 53. As described above, the one end 51 is pivotally supported by the pivot hole 33 and functions as a rotation shaft, and the other end 52 functions as a cam follower.

  Therefore, it is desirable that the one end 51 is inserted with less play with the pivot hole 33 compared to the other end 52 that simply moves in the cam groove 41. For example, the other end portion 52 may be inserted into the cam groove 41 with an accuracy of one side clearance of about 0.02 mm to 0.03 mm, but the one end portion 51 is pivotally supported with an accuracy of one side clearance of about 0.01 mm. It is desirable that the holes 33 be inserted.

  Further, as shown in FIG. 6, the one end portion 51 has a longer dimension than the other end portion 52 in order to reduce backlash with the pivotal support hole 33. Specifically, the one end portion 51 has a length of about 0.6 to 0.8 mm, and the other end portion 52 has a length of about 0.3 to 0.5 mm. Furthermore, a pilot portion 51 a that guides insertion into the pivotal support hole 33 is formed at the one end portion 51.

  The guide pin 5 has a total length of about 4 mm to 5 mm. Moreover, the one end part 51 and the other end part 52 are shaft shapes having a diameter of about 0.2 mm to 0.3 mm. Further, the front surface 54 and the back surface 55 of the intermediate portion 53 of the guide pin 5 are curved surfaces as shown in the left diagram of FIG. Since the surface 54 is a curved surface, friction between the guide pin 5 and a metal shell (not shown) is reduced, and the guide pin 5 easily swings. Further, the intermediate portion 53 has a width of about 0.35 mm to 0.45 mm.

  Thus, the functions of the one end 51 and the other end 52 are different from each other. Therefore, it is desirable that the one end portion 51 and the other end portion 52 have different shapes depending on their functions. However, if the guide pin 5 has directionality, there is a possibility that the direction of the guide pin 5 may be wrongly assembled during manual operation by a conventional worker or when the guide pin 5 is set on a jig or the like. It was difficult to have.

  FIG. 7 is an external view of the second plate-like member 59 that is a supply form of the guide pin 5 to the mold 100. The second plate member 59 is composed of a second metal long plate 56. A plurality of pilot holes 57 used for positioning are formed at predetermined intervals at the end of the second metal long plate 56 extending in the longitudinal direction. The second long metal plate 56 is a steel plate such as stainless steel having a thickness of about 0.2 mm to 0.3 mm. In addition, the material and thickness of the 2nd metal long plate 56 are not specifically limited.

  The guide pin 5 is formed by pressing the second long metal plate 56. The one end 51 and the other end 52 are formed by subjecting the second metal long plate 56 to a known concavity process. As shown in FIG. 7, the intermediate portion 53 is connected to the second long metal plate 56 by a connecting portion 58.

  The second plate-like member 59 is formed with a plurality of guide pin components 60 in which only one end portion 51 and the other end portion 52 are formed in the longitudinal direction with an interval of, for example, about 8 mm to 10 mm.

  Further, the guide pin component 60 is inclined by a predetermined angle with respect to the longitudinal direction of the second long metal plate 56. Specifically, the guide pin component 60 has an inclination of about 0.1 to 1 degree with respect to the longitudinal direction.

  The inclination of the guide pin component 60 is such that the line segment connecting the pivot hole 33 on the first plate member 27 and the position 41 a of the slider 4 is perpendicular to the longitudinal direction of the first metal long plate 23. It is equal to the angle of inclination.

  Next, the metal mold | die 100 which is one Embodiment of this invention is demonstrated. FIG. 8 is a structural diagram of the mold 100 of the present invention.

  On the lower mold of the mold 100, a pair of guide posts 101 for guiding the vertical movement of the upper mold is erected vertically with respect to the lower mold. An upper mold (not shown) of the mold 100 is guided by the guide post pair 101 and moves up and down relative to the lower mold. Further, the upper mold, the lower mold, and the parts described below are made of a known steel material, and are subjected to a known quenching treatment as necessary.

  A first guide plate 102 for guiding the horizontal feeding of the first plate-like member 27 is attached to the surface of the lower die, as indicated by 1 in FIG. In addition, the first guide plate 102 has a clearance 103 with respect to the width of the first plate member 27, and the disposal port 103 for discarding the second metal long plate 56 after the guide pin component 60 is separated as scrap. Are formed with first guide grooves 104 having a thickness of about 0.1 mm to 0.3 mm. The first guide plate 102 guides the horizontal feeding of the first plate member 27.

  On the first guide plate 102, a die block 105 is stacked above the first guide groove 104 as indicated by 2 in FIG. The die block 105 is formed with an I-shaped through hole 106 and a pair of pilot holes 110 through which pilot pins (not shown) attached to the upper die are inserted. As will be described later, the through hole 106 guides the insertion of the guide pin 5 into the pivotal support hole 33 and the cam groove 41.

  On the first guide plate 102, a die plate 107 for nesting and holding the die block 105 is laminated. The die plate 107 is formed with a second disposal port 108 communicating with the disposal port 103.

  A pilot pin (not shown) is inserted through the pilot hole 57 of the second plate member 59 to position the second plate member 59 with respect to the through hole 106. Therefore, the pitch of the pair of pilot holes 110 is the same as the pitch of the pilot holes 57 of the second plate member 59.

  The pair of second guide plates 111 form a second guide groove 112 having a clearance of about 0.1 mm to 0.3 mm with respect to the width of the second plate-like member 59. As a result, the pair of second guide plates 111 guides the feeding of the second plate member 59 in the vertical direction in FIG. The second plate-like member 59 is sent out so that the back surface thereof faces the die plate 107 so that the one end portion 51 and the other end portion 52 face downward.

  In the pair of second guide plates 111, recesses 111a extending in the longitudinal direction are formed on the back surfaces. The pair of second guide plates 111 cover both end portions of the second plate-like member 59 extending in the longitudinal direction.

  FIG. 9 is a view showing the appearance of the punch 120 used in the mold 100 of the present invention. The punch 120 includes a holding part 121 that is held by an upper mold (not shown), and a tip part 122 that is inserted through the die block 105 along with the upper mold. The holding part 121 is positioned and fixed to the upper mold so that the tip part 122 passes through the through hole 106.

  As described above, the distal end portion 122 is inserted through the through hole 106 and has a substantially I shape with a clearance of about 0.01 mm to 0.015 mm with respect to the through hole 106.

  FIG. 10 is a view showing a delivery mode of the first plate-like member 27. As described above, the first plate-like member 27 is guided by the first guide plate 102 and is sequentially fed on the first guide groove 104. A known grip feed mechanism, roll feed mechanism, or the like is used for the progressive means of the first plate-like member 27.

  The first plate-like member 27 is fed in units of the pitch of the main body part 28. Then, when a pilot pin (not shown) attached to the upper die is inserted through the pilot hole 24, the pivotal support hole 33 and the portion of the cam groove 41 at the position 41 a are positioned directly below the through hole 106. The one plate member 27 is sequentially positioned.

  FIG. 11 is a view showing a delivery mode of the second plate-like member 59. As described above, the second plate-like member 59 is guided by the pair of second guide plates 111 and is sequentially fed on the second guide grooves 112.

  The second plate-like member 59 is sequentially fed in pitch units of the guide pin component 60. A pilot pin (not shown) attached to the upper die is inserted through the pilot hole 57 and the pilot hole 110, whereby the guide pin component 60 is sequentially positioned on the through hole 106.

  As shown by the broken line in FIG. 11, the punch 120 has the tip 122 positioned immediately above the through hole 106. The guide pin component 60 is separated from the second plate-like member 59 by the distal end portion 122 passing through the through hole 106, and the guide pin 5 is formed.

  Further, the guide pin 5 formed by inserting the front end portion 122 through the through hole 106 is inserted into the main body component 28. The second plate-like member 59 after the guide pin 5 is separated is cut to a predetermined size and discarded as scrap from the disposal port 103 and the disposal port 108.

  FIG. 12 is an overall view of the mold 100 of the present invention. The first plate-like member 27 is sequentially fed to the mold 100 in the unit of the pitch of the main body component 28 in the horizontal direction of FIG. 12, and the second plate-like member 59 is moved up and down in FIG. The guide pin parts 60 are sequentially fed in the direction of the pitch.

  Then, when the upper mold is lowered, the guide pin component 60 is separated from the second plate-like member 59, and the guide pin 5 is formed. When the upper die is further lowered, the guide pin 5 is inserted into the main body part 28. Then, the main body part 28 with the guide pin 5 inserted is sequentially discharged from the mold 100.

  FIG. 13 is a view showing a manner of cutting the guide pin component 60 and inserting the guide pin 5. As shown in 1 of FIG. 13, the first plate-like member 27 is sequentially fed onto the first guide groove 104, and the pivotal support hole 33 and the cam groove 41 are positioned immediately below the through hole 106.

  The second plate-like member 59 is also sent out on the second guide groove 112, and the guide pin component 60 is positioned on the through hole 106. The first plate member 27 and the second plate member 59 are sent out substantially simultaneously in synchronization with the vertical movement of the upper mold.

  Then, when the leading end 122 of the punch 120 descends and comes into contact with the guide pin component 60 and starts to be inserted into the through hole 106, the cutting of the connecting portion 58 with the through hole 106 is started.

  When the distal end portion 122 further descends, as shown in 2 of FIG. 13, the connecting portion 58 is cut, and the guide pin component 60 is punched and separated from the second plate member 59. And the guide pin 5 is formed. The tip 122 further descends while pressing the guide pin 5 and passes through the through hole 106.

  The lowering guide pin 5 is guided by the through-hole 106, thereby maintaining the same posture as the guide pin component 60. When the distal end portion 122 further descends, as shown in 4 of FIG. 13, the one end portion 51 is inserted into the pivotal support hole 33 and the other end portion 52 is inserted into the cam groove 41, respectively. Then, the feeding of the first plate-like member 27 and the second plate-like member 59, the punching of the guide pin component 60, and the insertion of the guide pin 5 are sequentially repeated.

  As described above, according to the present embodiment, the pair of first guide plates 102 guides the first plate member 27 and feeds it into the mold 100, and the pair of second guide plates 111 has the second plate shape. The member 59 is guided and fed into the mold 100, and the punch 120 descends from above the pair of second guide plates 111 toward the die block 105, separating the guide pins 5 from the second plate-like member 59, and guiding. In order to insert the pin 5 through the through hole 106, and insert the one end portion 51 into the pivotal support hole 33 and the other end portion 52 into the cam groove 41, the main body components 28 are individually separated from the first plate member 27, There is no need to assemble the guide pins 5 one by one on the separated main body part 28, and the guide pins 5 can be sequentially inserted using the mold 100, so that the productivity of the card connector 1 can be improved and the equipment cost and work can be improved. It is possible to reduce the cost of labor expenses.

  In addition, according to the present embodiment, even when the guide pin 5 has directionality, the one end 51 is accurately inserted into the pivotal support hole 33 and the other end 52 is inserted into the cam groove 41 without making a mistake in directionality. This can improve productivity and reduce costs.

  The manufacturing method of the card connector and the mold thereof according to the present invention are not limited to the above embodiment, and can be appropriately changed without departing from the gist of the present invention.
