Description

  The present invention relates to a method of manufacturing a connector including a socket and a header that are coupled and electrically connected to each other.

  Conventionally, various connectors including a header and a header that are coupled and electrically connected to each other have been proposed and are commercially available. For example, as shown in FIGS. 10 to 13, a printed wiring board (for example, FPC (Flexible Printed), which includes a socket 50 (see FIGS. 10 and 11) and a header 70 (see FIGS. 12 and 13) and each is mounted. There has been provided a connector for electrically connecting a circuit) and a hard substrate (see, for example, Patent Document 1).

  As shown in FIG. 10, the socket 50 includes a socket body 51 made of a resin molded product formed in a flat rectangular parallelepiped shape, and a plurality of socket contacts 60 disposed on the socket body 51. Since the socket main body 51 is formed with the insertion groove 52 along the longitudinal direction in order to connect the header main body 71, the mechanical strength is weak and the socket main body 51 is easily deformed. In order to increase the mechanical strength of the socket main body 51, an elongated rectangular parallelepiped protruding base 53 projects from the bottom surface of the insertion groove 52 substantially vertically. A plurality of socket contacts 60 are arranged in two rows along the longitudinal direction of the socket body 51 on the peripheral walls 54, 54 on both sides of the insertion groove 52.

  The socket reinforcing metal fitting 56 is provided to reinforce the socket contact 60 when the socket contact 60 is soldered to the printed wiring board. The reinforcing metal fitting 56 is provided with one end portion 56a at the end portion 57 of the socket body 51 by press fitting, and the other end portion 56b is soldered to the printed wiring board.

  On the other hand, the header 70 is, as shown in FIG. 12, a header body 71 made of a resin molded product formed in a flat rectangular parallelepiped shape, and a plurality of socket contacts 60 (see FIG. 11) disposed in the header body 71. And a plurality of header contacts 80 that are in contact with each other. In the header body 71, a fitting groove 72 that fits the protrusion 53 is formed in a portion of the socket body 51 that faces the protrusion 53 along the longitudinal direction of the header 71. The peripheral walls 73, 73 on both sides of the fitting groove 72 are formed with flanges 74 that protrude substantially perpendicularly from the peripheral wall 73 at the edge of the header body 71 on the back side (printed wiring board side). Further, in the groove of the fitting groove 72, there are four fitting protrusions 75 that fit into the key groove 55 (see FIG. 9) provided in the projecting portion 53 of the socket body 51 in order to disperse the impact applied during fitting. Projected at the location. Further, a reinforcing metal fitting 76 is provided at an end 77 in the longitudinal direction of the header main body 71.

  The header contact 80 is formed by bending a band-shaped metal material. As shown in FIG. 13, the contact portion 61 (see FIG. 13) of the socket contact 60 is provided on the flange 74 side of the portion along the outer surface of the peripheral wall 73. 11), and a terminal portion 82 that is soldered to a conductive pattern (not shown) of the printed wiring board is formed at one end protruding from the collar portion 74, and insert molding is performed. Thus, the header body 71 is simultaneously molded.

  The header reinforcing bracket 76 is provided to reinforce the header contact 80 when the header contact 80 is soldered to the printed wiring board. The reinforcing metal fitting 76 is provided with one end 76a at the end 77 of the header body 71 by press-fitting, and the other end 76b is soldered to the printed wiring board.

The socket 50 (see FIG. 10) and the header 70 (see FIG. 12) are respectively connected to a conductive pattern (not shown) of a printed wiring board, a terminal portion 62 of each socket contact 60, and a terminal portion 82 of each header contact 80. It is mounted by soldering. When the header 70 is inserted into the insertion groove 52 of the socket 50, the protruding portion 53 of the socket 50 is fitted into the fitting groove 72 of the header 70, and the contact portion 61 of the socket contact 60 is in contact with the header contact 80. The printed circuit board on which the socket 50 is mounted and the printed circuit board on which the header 70 is mounted are electrically connected by elastic contact with the portion 81.

  However, the above conventional connectors have the following problems. Since the socket reinforcing metal fitting 56 is provided by press-fitting into the socket main body 51, the socket main body 51 needs to be thickened to ensure the strength in the vicinity of the reinforcing metal fitting 56, thereby increasing the size of the socket main body 51. There was also a problem. Similar problems occur in the header main body 71 shown in FIG.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a method for manufacturing a connector that can increase strength and can be miniaturized.

  The invention of claim 1 is a header comprising a plurality of pairs of header contacts soldered to one circuit board, a header body of an insulating member in which the plurality of pairs of header contacts are arranged in one direction, and Plural pairs of socket contacts to be soldered to other circuit boards, insertion grooves into which the header is inserted / extracted are formed, and when the header is inserted into the insertion grooves, the plurality of socket contacts are inserted inside the insertion grooves A connector having a socket having a socket body of an insulating member in which the plurality of pairs of socket contacts are arranged in the one direction so as to be conductively connected to the pair of header contacts, the connector including a plurality of pairs of conductive terminals A method of manufacturing a connector produced from a member, wherein a plurality of pairs of conductive terminals are arranged in a strip in a single direction on a strip-shaped metal plate by punching, Among the electrical terminals, a plurality of predetermined conductive terminals are used as the plurality of pairs of header contacts, and the plurality of pairs of header contacts are integrally formed with the header body, and at the same time, the conductive terminals on both sides of the plurality of pairs of header contacts. As the reinforcing metal fitting, the header is formed by integrally molding with the header main body.

  The invention of claim 2 is characterized in that, in the invention of claim 1, a conductive terminal provided with a pair of conductive terminals opened with the header contact is used as the reinforcing metal fitting.

  The invention of claim 3 is characterized in that, in the invention of claim 1 or 2, the tip end portion of the reinforcing metal fitting is formed with the same dimensions as the header body.

  According to the invention of claim 1, since the reinforcing metal fitting is integrally formed with the header body, the strength can be increased and the size can be reduced.

  According to the invention of claim 2, since the soldering portion of the reinforcing metal fitting can be enlarged, the soldering strength can be increased.

  According to the invention of claim 3, it is possible to prevent the reinforcing metal fitting from interfering with the socket when the header is inserted into the socket.

  First, the basic configuration of the present embodiment will be described with reference to FIGS. The connector of the present embodiment is a board-to-board connector that connects, for example, a flexible printed wiring board and a printed wiring board that is a rigid board, and includes a plurality of socket contacts 20 and socket contacts 20 as shown in FIG. A socket 10 having a socket body 11 arranged side by side, and a header 30 having a plurality of header contacts 40 in contact with each socket contact 20 and a header body 31 in which the header contacts 40 are arranged side by side. Composed.

  As shown in FIG. 2, the socket body 11 of the socket 10 is made of a resin molded product formed in a flat and substantially rectangular parallelepiped shape, and has an insertion groove 12 that is recessed in a rectangular shape along the longitudinal direction of the socket body 11. Is formed. At the time of resin molding of the socket body 11, a plurality of socket contacts 20 are inserted, and the plurality of socket contacts 20 are arranged in two rows on the peripheral walls 13 and 13 on both sides of the insertion groove 12 along the longitudinal direction of the socket body 11. Has been. In addition, a U-shaped guide wall 15 protrudes from the periphery of both ends in the longitudinal direction of the insertion groove 12 toward the header 30 on the surface of the socket body 11 facing the header 30 (see FIG. 4). The guide wall 15 is formed with an inclined surface 15a such that the protruding amount increases toward the outside from the insertion groove 12. In this way, when the header 30 is inserted into the insertion groove 12 of the socket body 11, the header 30 is guided by the inclined surface 15 a of the guide wall 15 provided at the peripheral edge of the insertion groove 12, and the insertion groove 12. Therefore, even if the relative position between the socket body 11 and the header body 31 is slightly shifted, the header 30 can be easily inserted into the insertion groove 12.

  Each socket contact 20 is made of a band-shaped metal material, and is formed in a U shape so as to sandwich the edge of the peripheral wall 13 along the longitudinal direction around the insertion groove 12 of the socket body 11 as shown in FIG. Between the holding part 21 held by the socket body 11 and the holding part 21 which is extended from the one end located inside the insertion groove 12 in the holding part 21 so as to form an S shape together with the holding part 21. A bending portion 22 that can be bent in a direction in which the distance is changed (that is, a direction that intersects the insertion / extraction direction of the header 30 with respect to the insertion groove 12), and an outer end that is located outside the insertion groove 12 in the holding portion 21. A band-shaped terminal portion 23 that is bent and protrudes in a direction substantially perpendicular to the peripheral wall 13 and is soldered to, for example, a conductive pattern (not shown) of a printed wiring board is provided continuously and integrally. Further, a contact convex portion 24 protruding in a direction away from the holding portion 21 is formed on the bent portion 22 by bending, and the contact convex portion 24 elastically protrudes in a direction intersecting with the insertion / extraction direction.

  Moreover, as shown in FIG. 2, the socket reinforcement metal fitting 14 is simultaneously shape | molded by the insert molding at the edge part 16 of the longitudinal direction of the socket main body 11. As shown in FIG. The socket reinforcing metal fitting 14 includes a fixed piece 14a protruding laterally from the bottom of the end portion 16, a U-shaped connecting piece 14b and an L-shaped extending piece 14c embedded and fixed in the end portion 16 (see FIG. 4). The fixed piece 14a is connected to the outside of the extending piece 14c, and the fixed piece 14a is disposed substantially flush with the terminal portion 23. The socket reinforcing metal fitting 14 fixes the fixing piece 14a to the land (not shown) of the printed wiring board when the terminal portion 23 of the socket contact 20 is soldered to the conductive pattern (not shown) of the printed wiring board. By doing so, the fixing strength of the socket body 11 to the circuit board can be reinforced, and the stress applied to the socket contact 20 when the connector is fitted can be reduced. Moreover, since the socket reinforcement metal fitting 14 is embed | buriedly fixed to the socket main body 11, the mechanical strength of the socket main body 11 can be improved. Furthermore, since the socket reinforcement metal fitting 14 is provided in the socket main body 11 by insert molding, the socket main body 11 does not need to ensure the thickness like the case where the socket reinforcement metal fitting is held by press fitting.

  As shown in FIG. 5, the header body 31 of the header 30 is made of a resin molded product formed in an elongated, substantially rectangular parallelepiped shape, and is formed at the center in the short direction on the surface facing the socket body 11 (see FIG. 2). The mounting groove 32 is formed along the longitudinal direction at the portion where the header contact 40 is disposed, and the peripheral wall 33, 33 on both sides of the mounting groove 32 has a peripheral wall on the rear side (opposite the socket 10) edge. A flange portion 34 is formed so as to protrude substantially vertically from 33. A plurality of header contacts 40 are arranged in two rows along the longitudinal direction of the header body 31 on the outer side surfaces of the peripheral walls 33 and 33 of the header body 31. In the groove of the mounting groove 32, a plurality of partition walls are formed integrally with the header body 31 to connect between the peripheral walls 33, 33 facing each other across the mounting groove 32 from the bottom to the opening of the mounting groove 32. Each partition wall 35 is disposed between adjacent header contacts 40 in the longitudinal direction of the header body 31.

  Further, the end portion 36 of the header main body 31 has an inclined surface 37a inclined inward from the upper side (left side in FIG. 5B) toward the lower surface (right side), and forms a recess 37. This recess 37 makes it easy to see a soldered portion when a later-described header reinforcing metal fitting 46 is soldered to a land 49 (see FIG. 1) of the circuit board, and can be easily soldered.

  Each header contact 40 is formed by bending a band-shaped metal material, and as shown in FIG. 5, is formed simultaneously with the header body 31 by insert molding, and the insertion / extraction direction of the peripheral wall 33 (the vertical direction in FIG. 8) ) Is formed on the side of the flange 34 on the outer surface along the contact surface 41 to contact the contact convex portion 24 (see FIG. 3) of the socket contact 20. A belt-like terminal portion 42 that is soldered to a conductive pattern (not shown) of the printed wiring board is formed at one end portion that protrudes from the flange portion 34. Each header contact 40 extends in a U shape from the tip end side (socket 10 side) of the contact portion 41, and sandwiches a portion (that is, the peripheral wall 33) between the end surface of the mounting groove 32 and the outer surface. A mounting portion 43 to be attached to the header body 31 is provided, and the socket contact 20 is hooked on the curved surface portion by the curvature radius of the curved surface portion (curved portion on the outer surface side) in contact with the socket contact 20 in the mounting portion 43. The minimum radius of curvature is set so as not to buckle.

  Further, in the contact portion 41 of the header contact 40, a protrusion 44 and a recess 45 are provided at a portion that contacts the contact convex portion 24 of the socket contact 20, and the header 30 is inserted into the socket 10 as shown in FIG. In the state inserted to the depth of the groove 12, the contact convex portion 24 is in contact with both side portions of the concave portion 45, and the protrusion 44 is located on the bottom surface side of the insertion groove 12 with respect to the contact convex portion 24. The protrusion 44 protrudes at a position farther from the terminal portion 42 than the middle in the length direction on the surface of the contact portion 41 on the side where the terminal portion 42 protrudes. An inclined surface 44 a is provided which is larger as the position is closer to 42. Further, as shown in FIG. 5C, the recess 45 has a groove shape extending along the sliding direction of the contact protrusion 24 (see FIG. 8). The inclined surface which is two planes which make the depth dimension of the recessed part 45 small is formed so that the end of the direction (right-and-left direction in a figure) which cross | intersects 24 sliding directions is made, and the cross section of the left-right direction of the recessed part 45 is formed. The shape is V-shaped.

  Here, the width dimension of the concave portion 45 in the direction intersecting the sliding direction of the contact convex portion 24 is formed smaller than the width dimension of the contact convex portion 24, and the concave portion 45 is slid on the contact convex portion 24 at the contact portion 41. In the process of inserting the header 30 into the insertion groove 12 of the socket 10, the contact convex portion 24 elastically contacts both side portions of the concave portion 45 in the contact portion 41. Further, in the contact convex portion 24, the width dimension of the protrusion 44 in the width direction of the header contact 40 is set to be the width dimension of the recess 45 so that the range in contact with the protrusion 44 does not overlap the range in contact with both sides of the recess 45. It is set even smaller than.

  According to this configuration, even if foreign matter adheres to the contact convex portion 24 of the socket contact 20 or the contact portion 41 of the header contact 40 before the socket 10 and the header 30 are coupled, the contact convex portion 24 is not contacted with the contact portion. In the process of sliding on the surface of 41, foreign matter can be dropped into the concave portion 45, so that the possibility of foreign matter being caught between the contact convex portion 24 and the contact portion 41 is lower than when the concave portion 45 is not provided. Become. That is, contact failure due to foreign matter is prevented, and the contact convex portion 24 contacts at two points on both sides of the concave portion 45, so that contact reliability can be improved. Further, since the concave portion 45 is provided in the sliding range of the contact convex portion 24 in the contact portion 41, the contact convex portion 24 is compared with the case where the concave portion 45 is provided at a position outside the sliding range of the contact convex portion 24. It is easier to drop the foreign matter adhering to the recess 45 into the recess 45.

  Further, when a force for pulling out the header 30 from the insertion groove 12 is applied, the contact convex portion 24 of the socket contact 20 abuts on the protrusion 44 of the header contact 40 and a resistance force is applied. There is also an advantage that the header 30 is difficult to be removed from the insertion groove 12. Even when the header 30 is inserted into the insertion groove 12, the contact protrusion 24 of the socket contact 20 abuts on the protrusion 44 of the header contact 40, but the protrusion dimension of the protrusion 44 becomes smaller as the position away from the terminal portion 42. Since the inclined surface 44 a is provided on the protrusion 44, the resistance when inserting the header 30 into the insertion groove 12 is smaller than the resistance when removing the header 30 from the insertion groove 12. Moreover, in the contact convex part 24, since the position and shape of the recessed part 45 are set so that the range which contacts the protrusion 44 and the range which contacts the both sides of the recessed part 45 may not overlap, the contact convex part 24 protrudes. The foreign matter pushed by the contact convex portion 24 when sliding on the surface of 44 is dropped into the concave portion 45 and is not caught between the contact convex portion 24 and the contact portion 41.

  Header reinforcing metal fittings 46 are provided at both longitudinal ends of the header body 31. The header reinforcing metal fitting 46 is a conductive terminal 48 (see FIG. 7) that becomes a loss pin when the header contact 40 is insert-molded, and is simultaneously molded by insert molding. Further, as shown in FIG. 6B, the header 46a has a terminal 46a that is substantially the same as both side surfaces of the header body 31 in the short direction (left and right direction in FIG. 6B). The terminal portion 46 a is shorter than the terminal portion 42 of the contact 40. Further, like the header contact 40, the header reinforcing metal fitting 46 is provided with a protrusion 46c and a recess 46d. At the time of insert molding, the resin for forming the header main body 31 is fitted into the protrusions 46c and the concave portions 46d, thereby strengthening the fixing of the header reinforcing bracket 46 and the header main body 31. In addition, since the header reinforcing metal fitting 46 is embedded and fixed in the header main body 31, the mechanical strength of the header main body 31 can be increased. Further, since the header reinforcing metal fitting 46 is provided in the header main body 31 by insert molding, the header main body 31 does not need to have a thickness as in the case where the header reinforcing metal fitting is held by press fitting.

  When the terminal portion 42 of the header contact 40 is solder-fixed to the conductive pattern (not shown) of the printed wiring board, the header reinforcing metal fitting 46 is solder-fixed to the land 49 (see FIG. 11) of the printed wiring board. By doing so, the fixing strength of the header body 31 to the printed wiring board can be reinforced, and the stress applied to the header contact 40 when the connector is fitted can be reduced. That is, the terminal portion 46a of the header reinforcing metal fitting 46 serving as a loss pin functions as a terminal reinforcing metal fitting.

  The insert molding of the header 30 will be described. As shown in FIG. 7A, conductive terminals 48 having the same shape as the header contact 40 are arranged at regular intervals on a strip-shaped metal plate 47 by punching (a1). Among the conductive terminals 48, the same number (for example, 15 pairs) of conductive terminals 48a as the header contacts 40 are left, and a pair of conductive terminals 48b are left from a plurality of pairs of conductive terminals 48 on both sides of the conductive terminals 48a. Then, the remaining conductive terminal 48 is cut and removed (a2). Then, it integrally molds with the resin which forms the header main body 31 (a3). Then, the tips of the pair of conductive terminals 48b are cut (a3). A side view at this time is shown in FIG. After the above steps, the respective conductive terminals 48a and 48b are cut from the metal plate 47 and the header 30 formed by insert molding is removed.

  Next, connection between the socket 10 and the header 30 will be described. The terminal part 23 of the socket contact 20 and the terminal part 42 of the header contact 40 are respectively soldered to separate circuit boards (not shown) such as a printed wiring board, and as shown in FIG. The header 30 is inserted into the insertion groove 12, and the plurality of socket contacts 20 and the header contact 40 are brought into contact with each other. At this time, as shown in FIG. 9, since the terminal portion 46a of the header reinforcing metal fitting 46 is short, the printed wiring boards can be electrically connected without contacting the guide wall 15 of the socket body 11.

  As described above, according to the present embodiment, the socket reinforcing bracket 14 is provided integrally with the socket body 11 and the header reinforcing bracket 46 is integrally formed with the header body 31, so that the strength of the connector can be increased. At the same time, the size can be reduced. Further, since the header reinforcing metal fitting 46 is provided at a distance from the header contact 40, the soldering strength of the header reinforcing metal fitting 46 can be increased. Further, the header 30 can be inserted into the socket 10 without the header reinforcing metal fitting 46 interfering with the socket body 11.

  In the present embodiment, the contact convex portion 24 is in elastic contact with both side portions of the concave portion 45 in the contact portion 41, and foreign matter is dropped into the concave portion 45 in the process in which the contact convex portion 24 slides on the surface of the contact portion 41. This reduces the possibility of foreign matter being caught between the contact convex portion 24 and the contact portion 41 and improves the contact reliability. However, the shape of the contact convex portion 24 and the contact portion 41 and the contact state thereof are improved. The surface of the contact convex portion 24 that contacts the contact portion 41 is not limited to the above-described form. The shape in which the intermediate portion in the width direction protrudes closer to the contact portion 41 than the both ends (for example, a curved shape) ) So that the intermediate portion in the width direction enters the concave portion 45 provided in the contact portion 41 and comes into contact with two inclined surfaces in the concave portion 45 or the opening edge of the concave portion 45 at two points. The contact convex part 24 and the contact part 41 are in contact with each other in a plane. Compared to the case, the contact area between the contact convex portion 24 and the contact portion 41 is reduced and the contact pressure is increased, so that foreign matter is easily discharged from between the contact convex portion 24 and the contact portion 41, and contact reliability is increased. Improves.
