Description

  The present invention relates to a manufacturing method for manufacturing a coaxial connector for a board to be attached to a printed board.

  As a conventional board shield connector attached to a printed circuit board, one shown in FIG. 17 is known. The board shield connector 10 includes an inner conductor terminal 11 soldered to a signal pattern on a printed board, and a connector terminal 14 in which the outer conductor terminal 13 accommodates the dielectric 12. The connector housing 15 is made of resin. A signal line of a shielded wire (not shown) is connected to the inner conductor terminal 11 so that a high frequency signal is transmitted. The outer conductor terminal 13 is connected to the shielded wire of the shielded wire, and the inner conductor terminal 11 Cover the surroundings and shield electromagnetically.

  The inner conductor terminal 11 is formed in a substantially inverted L shape in which a drooping portion 17 hangs downward from the base end of the pin-like horizontal portion 16 by punching a conductive plate material. The proximal end side of the pin-shaped horizontal portion 16 is formed to have a slightly larger diameter than the distal end side, and includes a locking projection 18. And the front end side of the horizontal part 16 is connected with the inner conductor terminal of the other party shield connector which is not shown in figure, and the front end side of the drooping part 17 is connected with the desired signal pattern of a printed circuit board, between a shield electric wire and a printed circuit board. The electrical signal is transferred.

  The dielectric 12 in which the inner conductor terminal 11 is accommodated is formed of a resin insulating material having a predetermined dielectric constant, and is assembled between the inner conductor terminal 11 and the outer conductor terminal 13. Between the two. In the dielectric 12, a storage chamber 20 having a vertically long opening surface 19 is formed inside, and a horizontal cylindrical portion 21 is formed to extend in front of the storage chamber 20.

  An insertion hole 22 into which the pin-like horizontal portion 16 of the inner conductor terminal 11 is inserted is formed in the horizontal cylinder portion 21 in the front-rear direction, and the rear side communicates with the storage chamber 20. When the horizontal portion 16 of the inner conductor terminal 11 is inserted into the insertion hole 22, the inner conductor terminal 11 is press-fitted by the locking protrusion 18 that is formed to bulge from the distal end side to the proximal end side having a slightly larger diameter. Is supposed to be retained.

  The outer conductor terminal 13 is formed in a cylindrical shape by punching a conductive plate material and then bent by a press or the like, and the dielectric 12 can be accommodated in the internal accommodation chamber 23. The front tip portion is a fitting portion 24 to be fitted with the outer conductor terminal of the mating shield connector, and the inner conductor terminal 11 inserted into the insertion hole of the dielectric 12 accommodated in the accommodation chamber 23. The tip of the horizontal portion 16 protrudes from the dielectric 12 and is disposed in the fitting portion 24.

  On the upper surface of the central portion of the outer conductor terminal 13, a locking piece 25 is provided so as to project upward and bendable. A bent piece 27 having a size covering the rear opening 26 is extended and formed at the rear end of the upper surface of the outer conductor terminal 13, and is accommodated in the accommodation chamber 23 of the outer conductor terminal 13 by bending downward. The dielectric 12 is covered from behind and the rear opening 26 is closed to prevent the shield performance of the board shield connector 10 from being deteriorated.

  At the rear portion of the outer conductor terminal 13, two connection portions 28 that are electrically connected to the ground pattern of the printed circuit board are formed extending downward. The connection portion 28 has a pair of elastic connection pieces 30 and 30 which are formed with slit-like voids and branch from the proximal end toward the distal end. A locking portion 31 is formed to bulge at the tip of the pair of elastic connection pieces 30 and 30 and can be locked to the opening edge of the through hole that is electrically connected to the ground pattern of the printed circuit board. (For example, refer to Patent Document 1).

  Thus, the board shield connector 10 is formed by punching the conductive plate material with the inner conductor terminal 11, and the outer conductor terminal 13 is formed by punching the conductive plate material and then bending it with a press. . The inner conductor terminal 11 is held by the dielectric 12, the dielectric 12 is accommodated in the accommodation chamber 23 of the outer conductor terminal 13, and the horizontal portion 16 of the inner conductor terminal 11 is inserted into the insertion hole 22 of the dielectric 12. The board shield connector 10 is assembled so as to be inserted and protruded.

  Hereinafter, a method for manufacturing a coaxial connector for a substrate according to an embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 3, the coaxial connector P for board manufactured according to this embodiment includes an outer housing (connector housing) 41, an outer terminal (outer conductor terminal) 42, and an inner terminal (inner conductor terminal). 43 and an inner housing E.

  The outer housing 41 accommodates portions of the outer terminal 42 and the inner terminal 43 that are connected to the outer terminal and the inner terminal of the mating connector inside at a predetermined interval. Here, the outer housing 41 covers the outer terminals 42 and the inner terminals 43, and the outer terminals 42 cover the inner terminals 43 at a predetermined interval. The outer terminal 42 and the inner terminal 43 are accommodated in a mold C which will be described later, and are formed into the above-described shape by hoop molding of the outer housing 41 with a synthetic resin (insulator, dielectric).

  The outer terminal 42 is somewhat longer than the inner terminal 43, and a gap G 1 into which the outer housing 41 of the mating connector can be inserted is provided between the outer housing 41 and the outer terminal 42. A gap G3 into which a part of the inner housing of the mating connector is inserted is provided between the inner terminal 43 and the inner terminal 43.

  Further, a gap G2 into which the outer housing of the mating connector is inserted is formed between the inner terminal 43 and the outer housing 41. Further, if necessary, fitting holes, guides, and the like are formed in the top and bottom portions of the outer housing 41 to fit the locking portions of the mating connector. As shown in FIG. 3, the portion E into which the synthetic resin is injected around the inner terminal 43 when the outer housing 41 is molded functions as the inner housing E that insulates the inner terminal 43 from the outer terminal 42.

  Next, details of the board coaxial connector P having such a configuration will be described with reference to FIGS. In the manufacturing method of the coaxial connector P for a board, as shown in FIGS. 4 to 8, an outer terminal A with a carrier and an inner terminal B with a carrier obtained by press forming a conductive metal plate are prepared, Used to overlap. 4 to 8 show the case where one outer terminal A or inner terminal B is extended to the carrier, the carrier has a plurality of outer terminals A or a plurality of inner terminals B. A chain is extended on one side of the carrier. In this way, a plurality of outer terminals A or a plurality of inner terminals B extended in a chain form is called a chain terminal. In addition, the outer terminal A or the inner terminal B that is connected to the carrier may be hereinafter referred to as an outer terminal A with a carrier or an inner terminal B with a carrier.

  As shown in FIG. 4, the outer terminal A with a carrier includes a band-shaped carrier 44 having a semicylindrical portion 44 a formed into a semicylindrical shape at a predetermined interval, and a notch portion from one side edge of the carrier 44. And a semi-cylindrical portion 45 continuous with the semi-cylindrical portion 44a through 45a. Note that the semi-cylindrical portion 44a and the semi-cylindrical portion 45 of the carrier 44 have the same diameter, and are continuous continuously through the notch 45a. The notch 45a is formed by cutting out a part of a semi-cylinder made up of the semi-cylindrical part 44a and the semi-cylindrical part 45 (a part adjacent to the carrier 44). It can be said that it constitutes a part of the semi-cylindrical portion 45. A plurality of positioning holes 46 are formed at predetermined intervals in the carrier 44 in one plane excluding the semi-cylindrical portion 44a. The semi-cylindrical portion 45 contacts the outer terminal of the counterpart coaxial connector when the board coaxial connector according to the embodiment of the present invention and the counterpart coaxial connector are fitted. Furthermore, when the coaxial connector for a board according to one embodiment of the present invention is mounted on a printed circuit board, the end of the semi-cylindrical part 44a of the carrier 44 (the end provided with the semi-cylindrical part 45 of the carrier 44) (The end on the opposite side) is soldered to the GND line of the printed circuit board.

  On the other hand, the carrier-equipped inner terminal B has, as shown in FIG. 5, a projecting piece 48 projecting from one side edge of the belt-like carrier 47 and a connecting piece 49 that is continuous with the projecting piece 48 and narrower (thin). The main body 50 rounded into a round shaft shape, the narrow projecting piece 51 coupled to the other side edge of the carrier 47, and the projecting piece 51 obliquely downward. It is comprised so that the inclined piece 52 and the terminal piece 53 which continues in a horizontal direction with respect to this inclined piece 52 may be provided. The carrier 47 is also provided with positioning holes 54 at predetermined intervals. When the board coaxial connector according to one embodiment of the present invention and the counterpart coaxial connector are fitted, the main body 50 contacts the inner terminal of the counterpart coaxial connector. Furthermore, when the coaxial connector for board according to the embodiment of the present invention is mounted on the printed board, the terminal piece 53 is soldered to the signal line of the printed board.

  The protruding piece 48 is a wide portion embedded in the outer housing 41, but its width is smaller than the inner diameter of the semi-cylindrical portion 45. For this reason, when the protruding piece 48 is disposed in the lower opening of the semi-cylindrical portion 45, the protruding piece 48 does not contact the semi-cylindrical portion 45. Furthermore, the width N of the carrier 47 is smaller than the width M of the notch 45a of the outer terminal A with a carrier. For this reason, when the inner terminal B with a carrier is disposed below the notch 45a, the carrier 47 does not contact the outer terminal A with a carrier.

  6, 7, and 8 are perspective views showing a state in which the carrier 44 of the outer terminal A with carrier and the carrier 47 of the inner terminal B with carrier are adjacent to each other in the front-rear direction and are installed in the same plane. It is a top view and a bottom view. As shown in FIGS. 6, 7, and 8, the carrier 44 of the outer terminal A with the carrier is arranged side by side on the side opposite to the side where the protruding piece 48 of the carrier 47 of the inner terminal B with the carrier is connected. That is, the outer terminal A with the carrier and the inner terminal B with the carrier are arranged side by side so that the carrier 47 of the inner terminal B with the carrier is positioned below the notch 45a of the outer terminal A with the carrier. When arranged in this manner, the protruding piece 48 does not contact the semi-cylindrical portion 45. Further, the carrier 44 and the carrier 47 are arranged in the same plane with a predetermined gap G4, and the carrier 47 of the inner terminal B with the carrier does not contact the carrier 44 of the outer terminal A with the carrier.

  Further, the protruding piece 48, the connecting piece 49, and the main body 50 of the inner terminal B with the carrier are located in the center part in the semi-cylindrical part 45 of the outer terminal A with the carrier, and a gap as shown in FIG. Keep G5. In the gap G5, in the vicinity of the protruding piece 48, a place where an insulator functioning as the inner housing E is injected (upper side of the protruding piece 48 in FIG. 8), and a first slide die 63 described later from the carrier 47 side. It is divided into a place to enter (the lower side in the drawing in the protruding piece 48 in FIG. 8).

  Therefore, when the outer terminal A with a carrier and the inner terminal B with a carrier are installed in the same plane as described above, there is no contact portion. Therefore, the outer terminal A with a carrier and the inner terminal B with a carrier are installed in a mold C, and a synthetic resin (insulator) is injected into the mold C to perform hoop molding. This forming process will be described with reference to FIGS.

  As shown in FIG. 9, the mold C includes a lower mold 61, an upper mold 62, a first slide mold 63, and a second slide mold 64. The lower mold 61 has a substantially rectangular container shape opened upward and downward. Since the upper surface of the U-shaped wall 65 is a contact surface with the upper mold 62, it is a smooth surface. The center of the upper surface of the front wall 65a in front of the U-shaped wall 65 supports the end of the semi-cylindrical portion 45 of the outer terminal A with carrier and the bottom surface of the protruding piece 48 of the inner terminal B with carrier from the lower side.

  On the other hand, the upper mold 62 is formed in a substantially rectangular container shape opened downward and rearward, and the front wall 67a of the U-shaped wall 67 has semicircular holes (semicircular cutouts) 68 extending through the front and rear surfaces and the lower surface thereof. Is formed. The shape and size of the semicircular hole 68 are equal to the shape and size of the semicylindrical portion 45 of the outer terminal A with a carrier. The lower surface of the semicircular hole (semicircular cutout) 68 in the front wall 67a of the U-shaped wall 67 supports the upper surface of the semicylindrical portion 45 of the outer terminal A with a carrier from the upper side. In this way, the upper mold 62 accommodates the part from the semi-cylindrical part 45 of the outer terminal A with carrier and the protruding piece 48 of the inner terminal B with carrier to the main body part 50.

  Further, as shown in FIG. 11, the first slide die 63 has a semi-cylindrical shape whose cross section is the same semicircle as the inner surface of the semi-cylindrical portion 44 a and the semi-cylindrical portion 45 of the outer terminal A with a carrier. . The first slide die 63 enters in the direction of the arrow c from the opening of the semicylindrical portion 44a of the outer terminal A with a carrier toward the semicylindrical portion 45. At this time, the first slide mold 63 has a U-shaped wall 67 with a tip end surface along the inner surface of the semicylindrical portion 44 a, the upper surface of the carrier 47, the inner surface of the semicylindrical portion 45, and the upper surface of the protruding piece 48. To the position where it is flush with the inner side surface of the front wall 67a (that is, the tip surface enters until the top surface is located on the upper surface of the protruding piece 48).

  The second slide mold 64 includes a substantially rectangular closing plate portion 69 and a rectangular portion 70 connected to the front side of the closing plate portion 69. The closing plate portion 69 functions to close the open ends of the rear portions of the lower die 61 and the upper die 62 when the lower die 61 and the upper die 62 are closed. The rectangular portion 70 has a rectangular cross section, and a substantially circular long hole 71 is provided at the center of the rectangular portion 70 from the front surface to a predetermined depth. Further, a semi-cylindrical hole 72 centering on the long hole 71 is formed. The main body 50 of the inner terminal B with a carrier is accommodated in the long hole 71, and the semicylindrical part 45 of the outer terminal A with a carrier is accommodated in the semicylindrical hole 72.

  The second slide mold 64 will be further described. A thick portion 73 shown in FIG. 11 extending from the upper outer peripheral surface of the rectangular portion 70 to the semi-cylindrical hole 72 has a thickness and a shape corresponding to the gap G1 of the outer housing 41 shown in FIG. Further, the thick portion 74 from the semi-cylindrical hole 72 to the long hole 71 has a thickness and shape corresponding to the gap G3 shown in FIG. Furthermore, the thickness 75 from the long hole 71 to the lower outer peripheral surface of the rectangular portion 70 is set to a thickness and shape corresponding to the gap G2.

  Therefore, the outer terminal A with a carrier and the inner terminal B with a carrier are arranged between the lower mold 61 and the upper mold 62 as shown in FIG. 9 and are moved in the directions of arrows a and b, respectively. Further, the first slide mold 63 and the second slide mold 64 arranged before and after the lower mold 61 and the upper mold 62 are moved in the directions of the arrows c and d, respectively. Thus, the semi-cylindrical portion 45 of the outer terminal A with carrier and the protruding piece 48 of the inner terminal B with carrier are the lower surface of the semicircular hole 68 of the upper die 62, the upper and lower surfaces of the first slide die 63, and the lower die. 61 is supported by the upper surface of the front wall 65a. At the same time, the semi-cylindrical portion 45 of the outer terminal A with carrier and the main body portion 50 of the inner terminal B with carrier are inserted into the semi-cylindrical hole 72 and the long hole 71 of the second slide die 64, respectively. As shown, an outer terminal A with a carrier and an inner terminal B with a carrier are housed in a mold C.

  Thereafter, an insulating material (synthetic resin) is injected into the gaps G1 to G3 surrounded by the molds 61 to 64 by a known method. When the synthetic resin is injected in the closed state, the outer terminal A with carrier and the inner terminal B with carrier are in close contact with the respective molds 61 to 64, and therefore the injected synthetic resin is the molds 61 to 64. There is no leakage outside.

  Then, after the synthetic resin is solidified, the molds 61 to 64 are moved in the direction opposite to the directions of the arrows a to d to perform mold opening. By this mold opening, a coaxial connector D with a carrier as shown in FIGS. 13 and 14 is formed. The coaxial connector D for substrates with a carrier is the same as the coaxial connector P for substrates described with reference to FIGS. 1 to 3 except that the carrier remains, and thus the description thereof is omitted.

  Next, as shown in FIGS. 15 and 16, for the above-described coaxial connector D for a substrate with a carrier, three carrier-cut lower dies 81 to 83 and four carrier-cut upper dies 84 to 87 are used. Then, the carriers 44 and 47 of the outer terminal A with carrier and the inner terminal B with carrier are cut. Of these, the carrier-cut lower dies 81 and 82 are formed in a rectangular shape with a steel material, and these blades are flat in one place of the carrier 44 of the outer terminal A with a carrier, specifically, in the vicinity of the semicylindrical portion 44a. Install so that the blade is positioned at the part.

  Moreover, the carrier cut lower mold | type 83 is formed in a rectangular shape, and arrange | positions in the position which supports the location connected with the protrusion piece 48 of the carrier 47 of the inner terminal B with a carrier over a predetermined range. At this time, the blade is disposed at a position slightly inside the inner surface of the semi-cylindrical portion 45 of the carrier 47. These blades become carrier cut positions L1 and L2 with respect to the outer terminal A with a carrier and the inner terminal B with a carrier. The carrier cut positions L1 and L2 are not in the same straight line, and the carrier cut position L2 is located inside L1. This is because if the carrier cut positions L1 and L2 are on the same straight line, the outer terminal and the inner terminal may come into contact with each other at the location where the carrier is cut.

  The carrier cut upper molds 84 and 85 are also rectangular, facing the carrier 44 of the outer terminal A with a carrier, and each blade thereof faces the carrier cut position L1. Further, the carrier cut dies 86 and 87 are also rectangular, facing the carrier 47 of the inner terminal B with the carrier, and the blade thereof faces the carrier cut position L2.

  Therefore, among the carrier-cut lower dies 81 to 83 and the carrier-cut upper dies 84 to 87 interposing the outer terminal A with a carrier and the inner terminal B with a carrier that are overlapped as described above, the carrier-cut upper dies 84 to 87 are indicated by arrows. Down in the Q direction. As a result, the carrier 44 of the outer terminal A with carrier and the carrier 47 of the inner terminal B with carrier are cut at the carrier cut positions L1 and L2, respectively. As a result, the coaxial connector P for a board as shown in FIGS. Will be obtained. In addition, since each blade of the carrier cut molds 86 and 87 passes through the cutout portion 45a of the outer terminal A with a carrier and moves toward the carrier cut position L2 when down in the direction of the arrow Q, the carrier cut mold 86, 87 does not destroy the semi-cylindrical portion 44a and the semi-cylindrical portion 45 of the outer terminal A with a carrier.

  As described above, according to the coaxial connector for substrates according to the embodiment of the present invention, the coaxial connector D for substrates with carrier can be obtained efficiently and easily by one hoop molding of the outer terminal A with carrier and the inner terminal B with carrier. Thus, the board coaxial connector P can be manufactured easily and at low cost without requiring a plurality of press-fitting operations of the terminal and the housing as in the prior art.
