Description:
TECHNICAL FIELD 
       [0001]    The present invention is related to a coaxial connector for a board attached to a printed board, a pair of chain terminals used for the coaxial connector for the board, and a method of manufacturing the coaxial connector for the board. 
       BACKGROUND ART 
       [0002]    As a shield connector for a board of the conventional art attached to the printed board, a connector shown in  FIG. 18  is known. The shield connector  10  for the board is configured such that a connector terminal  14 , in which an inner conductor terminal  11  soldered to a signal pattern on a printed board is held in an inner portion of a dielectric body  12 , and an outer conductor terminal  13  accommodates the dielectric body  12 , is accommodated in a connector housing  15  made of resin. A signal line of a shield electric wire (not shown) is connected to the inner conductor terminal  11 , and a high frequency signal is transmitted to the inner conductor terminal  11 . The outer conductor terminal  13  is connected to a shield line of the shield electric wire, and covers and electromagnetically shields the periphery of the inner conductor terminal  11 . 
         [0003]    The inner conductor terminal  11  is formed in a substantially inverted L shape in which a suspended portion  17  is suspended downward from a proximal end of a pin-shaped horizontal portion  16 , by punching a conductive plate member. The proximal end side of the pin-shaped horizontal portion  16  is formed to have a diameter slightly greater than the tip side thereof, and includes a locking protrusion  18 . Moreover, the tip side of the horizontal portion  16  is connected to the inner conductor terminal of an opposite side shield connector (not shown), and the tip side of the suspended portion  17  is connected to a desired signal pattern of printed board, whereby the delivery of the electric signal between the shield electric wire and the printed board is performed. 
         [0004]    The dielectric body  12 , in which the inner conductor terminal  11  is accommodated, is formed by an insulating material made of resin having a predetermined dielectric constant, is assembled between the inner conductor terminal  11  and the outer conductor terminal  13 , and sets the portion between these terminals to an insulated state. The dielectric body  12  is formed with an accommodation chamber  20  having an elongated opening surface  19  in an inner portion thereof, and a horizontal cylinder portion  21  is extended and formed in the front side of the accommodation chamber  20 . 
         [0005]    An insertion hole  22 , into which the pin-shaped horizontal portion  16  of the inner conductor terminal  11  is inserted, is opened and formed in the inner portion of the horizontal cylinder portion  21  in the front and back direction, and the back side thereof communicates with the accommodation chamber  20 . When the horizontal portion  16  of the inner conductor terminal  11  is inserted into the insertion hole  22 , the horizontal portion  16  is pressed by the locking protrusion  18  bulged to the proximal end side having a diameter slightly greater than the tip side, and the inner conductor terminal  11  is held in the dielectric body  12 . 
         [0006]    After releasing the conductive plate member, the outer terminal  13  is formed in a cylindrical shape by the bending processing using a press or the like, and the dielectric body  12  is able to be accommodated in the accommodation chamber  23  of the inner portion. The front tip portion is a fitting portion  24  fitted to the outer conductor terminal of the opposite side shield connector, and the tip of the horizontal portion  16  of the inner conductor terminal  11  inserted into the insertion hole  22  of the dielectric body  12  accommodated to the accommodation chamber  23  is projected from the dielectric body  12  and is placed in the fitting portion  24 . 
         [0007]    On an upper surface of a middle portion of the outer conductor terminal  13 , a locking piece  25  is projected so as to be possible to be flexural-deformed upward. On an upper surface rear end of the outer conductor terminal  13 , a folded piece  27  having a size covering the back opening portion  26  is extended and formed. The folded piece  27  covers the dielectric body  12  accommodated in the accommodation chamber  23  of the outer conductor terminal  13  from the back by being folded downward to block the back opening portion  26 , whereby it is possible to prevent degradation of the shield performance of the shield connector  10  for the board. 
         [0008]    Two connection portions  28  electrically connected to a ground pattern of the printed board are extended downward to the rear part of the outer conductor terminal  13 . The connection portions  28  have a pair of elastic connection pieces  30  and  30  that is formed with a slit-shaped gap portion and branches from the proximal end to the tip. Locking portions  31  bulge from the tips of the pair of elastic connection pieces  30  and  30 , and can be locked with an opening edge of a through hole that is electrically connected to the ground pattern of the printed board (for example, see PTL 1). 
         [0009]    In this manner, the shield connector  10  for the board is configured so that the inner conductor terminal  11  is formed by punching the conductive plate member, and the outer conductor terminal  13  is formed by being folded by a press after releasing the conductive plate member. Moreover, the inner conductor terminal  11  is held in the dielectric body  12 , the dielectric body  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 and protrudes from the insertion hole of the dielectric body  12 , so that the shield connector  10  for the board is assembled.

     DESCRIPTION OF EMBODIMENTS 
       [0056]    Hereinafter, the coaxial connector for the board, the pair of chain terminals used for the coaxial connector for the board, and the manufacturing method of manufacturing the coaxial connector for the board according to an embodiment of the present invention will be described with reference to the drawings. As shown in  FIGS. 1 to 3 , a coaxial connector P for a board manufactured by the present embodiment includes an outer housing (a connector housing)  41 , an outer terminal (an outer conductor terminal)  42 , an inner housing (a dielectric body)  43 , and an inner terminal (an inner conductor terminal)  44 . 
         [0057]    The outer housing  41  receives the outer terminal  42  in an inner portion thereof, and the inner terminal  44  is received in the inner portion of the outer terminal  42  via the inner housing  43 . Herein, the outer housing  41  mainly covers the outer portion of the outer terminal  42 , and the inner housing  43  covers the inner terminal  44 . The outer terminal  42  and the inner terminal  44  are accommodated in a mold C described below, and are formed in a shape mentioned above by a hoop molding using a synthetic resin (an insulating material and a dielectric body) of the outer housing  41  and the inner housing  43 . 
         [0058]    The outer terminal  42  and the inner terminal  44  have substantially the same length over their overall lengths, and the outer housing  41  has a length sufficiently longer than the overall length of the outer terminal  42  and the inner terminal  44 . A gap G 1 , into which an outer housing (not shown) of an opposite side connector can be inserted, is formed between the outer housing  41  and the outer terminal  42 , and a gap G 2 , into which an inner housing (not shown) of an opposite side connector is inserted, is formed between the outer terminal  42  and the inner housing  43 . Additionally, a gap G 3 , into which an inner terminal (not shown) of an opposite side connector is inserted, is formed between the inner housing  43  and the inner terminal  44 . A top portion and a bottom portion of the outer housing  41  are formed with fitting holes  45  fitted to locking portions of the opposite side connector, guide recesses  46  guiding the opposite side connector into the outer housing  41  during fitting or the like. 
         [0059]    Next, the details of the coaxial connector P for the board of the configuration mentioned above, and the manufacturing method of manufacturing the coaxial connector P for the board will be described with reference to  FIGS. 4 to 17 . As shown in  FIGS. 4 to 8 , with regard to the manufacturing method of the coaxial connector for the board, an outer terminal A with a carrier and an inner terminal B with a carrier obtained by the press molding of the conductive metal plate are prepared, and these terminals are used so as to overlap each other. Furthermore, in  FIGS. 4 to 8 , a case is shown where one outer terminal A or inner terminal B is extended to the carrier. However, in the carrier, a plurality of outer terminals A or a plurality of inner terminals B is extended to one side of the carrier in a chain shape. In this manner, a configuration, in which the plurality of outer terminals A or the plurality of inner terminals B is extended in a chain shape, is called a chain terminal. Furthermore, hereinafter, the outer terminal A or the inner terminal B, which is in the state of being extended to the carrier, is called the outer terminal A with the carrier or the inner terminal B with the carrier. 
         [0060]    As shown in  FIG. 4 , the outer terminal A with the carrier has a rising portion  48  which is raised from a side edge of a band-like carrier  47  in one plane at a predetermined height, a horizontal portion  49  which is substantially horizontally extended from the upper end of the rising portion  48  in the width direction (direction of the arrow Q), a short piece portion  50  which is extended to the side portion of the horizontal portion  49  end in a direction substantially perpendicular to the horizontal portion  49 , an L-shaped portion  51  which is extended vertically downward in the short piece portion  50  and is formed in a substantially L shape, an extended portion  52  which is extended from the middle of the L-shaped portion  51  in the direction of the arrow Q (a horizontal direction) of the carrier  47  and is in the same plane as the L-shaped portion  51 , a small L-shaped portion  53  which is continued from the extended portion  52  end vertically downward and is in the same plane as the extended portion  52 , and a partial recess  54  which is extended to the L-shaped portion  53  end and faces the small L-shaped portion  53 . Members from reference numeral  48  to reference numeral  53  are extended from the half-cylinder portion  55  opened downward (members from reference numeral  48  to reference numeral  53  are referred to as the extended portion). Moreover, the half-cylinder portion  55  is extended on the opposite side of the L-shaped portion  53  of the half-cylinder portion  55 , and integrally includes a wide connection portion  56  rising in the vertical direction, and a protrusion portion  57  extended to the lower portion of the connection portion  56  end and forming a substantially L shape together with the connection portion  56 . The half-cylinder portion  55  comes into contact with the outer terminal of the opposite coaxial connector, when fitting the coaxial connector for the board and the opposite coaxial connector according to an embodiment of the invention are fitted to each other. Furthermore, when the coaxial connector for the board according to an embodiment of the invention is mounted to the printed board, the L-shaped portion  51  is soldered to a GND line of the printed board. 
         [0061]    Meanwhile, as shown in  FIG. 5 , the inner terminal B with the carrier integrally includes a horizontal portion  59  which is horizontally extended from one side edge of a band-like carrier  58  in one horizontal plane in the direction of the arrow Q, a support portion  61  which is continued to one side edge of the horizontal portion  59  end via the short connection portion  60  and is horizontally extended in the direction of arrow Q, a short slope portion  62  which is separated from the connection portion  60  and slopes downward in an opposite direction of the arrow Q over a predetermined length, and a horizontal portion  63  which is horizontally extended to the lower portion of the slope portion  62 . A main body portion  64 , in which a tip is processed in a truncated conical shape, is extended to end of the support portion  61  in the direction of the arrow Q (the members from reference numeral  59  to reference numeral  61  are referred to as extended portions). When fitting the coaxial connector for the board according to an embodiment of the present invention and the opposite coaxial connector, the main body portion  64  comes into contact with the inner terminal of the opposite coaxial connection. Furthermore, when the coaxial connector for the board according to an embodiment of the invention is mounted to the printed board, the horizontal portion  63  is soldered to the signal line of the printed board. 
         [0062]    The length from the carrier  58  to the tip of the main body portion  64  and the length from the carrier  47  to the tip of the half-cylinder portion  55  are substantially equal to each other. The lengths (the widths) of the carriers  47  and  58  in the direction of the arrow Q are substantially equal to each other. Furthermore, the carrier  47  is formed with a positioning hole  65  in an opposite part of the rising portion  48 , and the carrier  58  is formed with a positioning hole  66  in an opposite part of the horizontal portion  63 . Accordingly, in a state where the carrier  47  is superimposed on the carrier  58  as shown in  FIG. 6  so that the positioning holes  65  and  66  coincide with each other, the horizontal portion  59  and the horizontal portion  63  are placed so that they are not vertically superimposed on each other with respect to the horizontal portion  49 . 
         [0063]      FIGS. 6 ,  7  and  8  are a perspective view, a plan view and a bottom view that show a state where the outer terminal A with the carrier and the inner terminal B with the carrier are superimposed on each other, respectively. From the drawings, the horizontal portion  59 , the horizontal portion  63 , the connection portion  60  and a part (substantially, a half portion) of the support portion  61  of the inner terminal B with the carrier are not superimposed on the rising portion  48 , the horizontal portion  49 , the short piece portion  50 , the L-shaped portion  51 , the connection portion  52 , and the L-shaped portion  53  of the outer terminal A with the carrier in the vertical direction, respectively. As a result, when a mold C described below is sandwiched between the outer terminal A with the carrier and the inner terminal B with the carrier of the superimposed state from up and down, and the outer terminal A with the carrier and the inner terminal B with the carrier are accommodated in the inner portion of the mold C, it is possible to sandwich the rising portion  48 , the horizontal portion  49 , the short piece portion  50 , the L-shaped portion  51 , the extended portion  52  and the L-shaped portion  53  of the outer terminal A with the carrier, and the horizontal portion  59 , the horizontal portion  63 , the connection portion  60  and a part (a substantially half portion) of the support portion  61  of the inner terminal B with the carrier from up and down. On the contrary, there is a location superimposed in the vertical direction, in this location, the upper mold comes into one of the inner terminal or the outer terminal positioned on the upper side and cannot be moved further downward than that, and the mold of the other side comes into contact with the one mold positioned on the lower side and cannot be moved further upward than that. For this reason, the location cannot be sealed by the mold, and when causing the insulating material to flow therein, the insulating material leaks from the location. In the present embodiment, since it is possible to sandwich the rising portion  48 , the horizontal portion  49 , the short piece portion  50 , the L-shaped portion  51 , the extended portion  52  and the L-shaped portion  53  of the outer terminal A with the carrier, and the horizontal portion  59 , the horizontal portion  63 , the connection portion  60  and a part (a substantially half portion) of the support portion  61  of the inner terminal B with the carrier from vertical, the outer terminal A and the inner terminal B can be sealed by the mold. Thus, when causing the insulating material to flow therein, the insulating material does not leak. 
         [0064]    The remainder of the support portion  61  of the inner terminal B with the carrier and the main body portion  64  continued thereto face the center portion of the half-cylinder portion  55  in the outer terminal A with the carrier, and a gap  67  for an insulating material injection becoming the inner housing  43  is sandwiched between the main body portion  64  and the half-cylinder portion  55  as shown in  FIG. 6 . 
         [0065]    Next, a case will be described where the outer terminal A with the carrier and the inner terminal B with the carrier are received in the mold C, and the synthetic resin (the insulating material) is injected into the mold C to mold a hoop, based on  FIGS. 9  to  12 . As shown in  FIG. 9 , the mold C includes a lower mold  71 , an upper mold  72 , and a slide mold  73 . 
         [0066]    The lower mold  71  forms a substantially rectangular container shape opened upward and rearward. A pair of protrusions  75  and  76  is projected upward from an upper surface of a front wall  74   a  in the front of a U-shaped wall  74 . The upper surface of the U-shaped wall  74  is an abutting surface relative to the upper mold  72  and thus is a flat surface. 
         [0067]    The upper mold  72  forms a substantially rectangular container shape opened downward and rearward, and a front wall  77   a  of a front part of the U-shaped wall  77  is formed with a pair of slit grooves  78  and  79  falling in the front and back surfaces and the lower surface. The slit grooves  78  and  79  have sizes and shapes capable of fitting the extended portion  52  and the connection portion  56  of the outer terminal A with the carrier sandwiched between the lower mold  71  and the upper mold  72 , and the protrusions  75  and  76  as described below. When the protrusions  75  and  76  are further fitted in a state where the extended portion  52  and the connection portion  56  are fitted, the inner portions of the slit grooves  78  and  79  are buried by the extended portion  52 , the connection portion  56 , and the protrusions  75  and  76 . Furthermore, a rectangular notch  80  falling in the front and back surfaces and the lower surface is formed near the center portion of the front wall  77   a.  The notch  80  has a size and a shape capable of fitting the horizontal portion  59  of the inner terminal B with the carrier. When the horizontal portion  59  is fitted, the inner portion of the notch  80  is buried by the horizontal portion  59 . In this manner, since the slit grooves  78 ,  79  and the notch  80  are in the buried state, the synthetic resin injected into the mold from here does not leak. 
         [0068]    The slide mold  73  includes a substantially rectangular plate shielding portion  81  shown in  FIG. 9  and a transverse cylinder portion  82  integrally projected from the front surface side of the plate shielding portion  81 . The plate shielding portion  81  functions so as to seal the rear opening formed by the lower mold  71  and the upper mold  72  when the lower mold  71  and the upper mold  72  are closed. Furthermore, the transverse cylinder portion  82  has the external form of a rectangular cross-section, and the center portion thereof is formed with a substantially circular long hole  83  from the front side of the transverse cylinder portion  82  over a predetermined depth. 
         [0069]    Herein, a thick portion  84  from an outer peripheral (outer) surface of the transverse cylinder portion  82  to the long hole  83  has a thickness and a shape corresponding to the gap G 1  of the outer housing  41  shown in  FIG. 2 . Furthermore, a cylinder portion  85  of a predetermined length is projected from a lower center portion in the long hole  83  in the axial direction, and a cylinder portion  86  of a large diameter shorter than the cylinder portion  85  is projected from the outer peripheral direction of the cylinder portion  85  similarly in the axial direction. 
         [0070]    The cylinder portion  85  has a thickness and a shape corresponding to the gap G 3  shown in  FIG. 2 , and the cylinder portion  86  has a thickness and a shape corresponding to the gap G 2  shown in  FIG. 2 . Furthermore, a gap G 4  shown in  FIG. 11 , which is formed when the lower mold  71 , the upper mold  72  and the slide mold  73  are closed (the molds are clamped), has a thickness and a shape corresponding to the outer housing  41  shown in  FIG. 2 . 
         [0071]    Thus, the outer terminal A with the carrier and the inner terminal B with the carrier, in which the carriers  47  and  58  are superimposed on each other, are placed between the lower mold  71  and the upper mold  72 , the respective molds  71  and  72  are moved in the direction of arrows a and b of  FIG. 9 , and the slide mold  73  is inserted into the rear opening end sides of the respective molds  71  and  72  in the direction of the arrow c. As a result, as shown in  FIGS. 10 and 11 , the mold closing is performed in the state where the outer terminal A with the carrier and the inner terminal B with the carrier, in which the carriers  47  and  58  are superimposed on each other, surround the periphery thereof by the lower mold  71 , the upper mold  72  and the slide mold  73 . Next, the insulating material (the synthetic resin) is injected into the gaps G 1  to G 4  surrounded by the respective molds  71  and  72  using a known method. When closing the mold, the respective molds  71  to  73  are joined to each other in a sealed manner, and the extended portion  52  and the connection portion  56  of the outer terminal A with the carrier and the protrusions  75  and  76  of the lower mold  71  are inserted into the slit grooves  78  and  79  of the upper mold  72  in a sealed contact state. For this reason, the insulating material injected into the respective molds  71  to  73  does not leak to the outside. 
         [0072]    Moreover, the mold is opened by moving the respective molds  71  to  73  in an opposite direction to the direction of arrows a to c after the solidification of the synthetic resin. As a consequence, the coaxial connector D for the board with the carrier as shown in  FIGS. 13 and 14  is formed. 
         [0073]    Next, as shown in  FIGS. 15 to 17 , with respect to the coaxial connector D for the board with the carrier as mentioned above, the outer terminal A with the carrier and the inner terminal B with the carrier are cut by using the carrier cut lower mold  91  and the carrier cut upper mold  92 . The carrier cut lower mold  91  is formed in formed in an L shape at the upper end portion thereof by a steel material of a predetermined thickness, an upper side thereof becomes an upper blade  93 , and a lower side thereof becomes a lower blade  94 . A blade edge of the upper blade  93  supports a portion continued to the short piece portion  50  of the horizontal portion  49  of the outer terminal A with the carrier from below, and a blade edge of the lower edge  94  supports a portion in which the horizontal portion  59  of the inner terminal B with the carrier is continued to the connection portion  60 , and a portion in which the horizontal portion  63  is continued to the slope portion  62 , from below. 
         [0074]    Furthermore, the carrier cut upper mold  92  includes a horizontal blade  95  and a vertical blade  96  having an L shape in the vertical direction through a steel material of a predetermined thickness. The respective blade edges of the horizontal blade  95  and the vertical blade  96  are provided at a position facing the upper blade  93  and the lower blade  94  of the carrier cut lower mold  91 , and are held in a positional relationship in which the carrier cut upper mold  92  does not interfere with the carrier cut lower mold  91  in the vertical direction. 
         [0075]    Thus, the carrier cut lower mold  91  and the carrier cut upper mold  92  are placed with respect to the outer terminal A with the carrier and the inner terminal B with the carrier of the coaxial connector D for the board with the carrier, as mentioned above. Moreover, the carrier cut upper mold  92  is hit down against the carrier cut lower mold  91  in the direction of arrow R. As a result, the outer terminal A with the carrier is cut by a cut line  1  of  FIG. 4 , and at the same time, the inner terminal B with the carrier is cut by a cut line  2 , whereby the coaxial connector P for the board as shown in  FIGS. 1 to 3  is obtained. 
         [0076]    This is more like predominantly acts, even when cutting the outer terminal A with the carrier and the inner terminal B with the carrier, the horizontal portion  59 , the horizontal portion  63 , the connection portion  60  and a part (substantially a half portion) of the support portion  61  of the inner terminal B with the carrier are not vertically superimposed on the rising portion  48 , the horizontal portion  49 , the short piece portion  50 , the L-shaped portion  51 , the extended portion  52 , and the L-shaped portion  53  of the outer terminal A with the carrier. That is, if there is a location superimposed in the vertical direction, in that location, one of the inner terminal and the outer terminal is pressed against the carrier cut lower mold or the carrier cut upper mold and is folded, and is cut in this state. In this case, the inner terminal or the outer terminal is unintentionally deformed. Moreover, even if the deformation is allowed, the inner terminal and the outer terminal may communicate with each other in the cut location. In the present embodiment, when cutting the outer terminal A with the carrier and the inner terminal B with the carrier, it is possible to prevent the inner terminal or the outer terminal being unintentionally deformed and the inner terminal and the outer terminal communicate with each other. 
         [0077]    As mentioned above, with the coaxial connector P for the board according to the embodiment of the invention, the coaxial connector for the board can be manufactured by the process smaller than the number of processes required for manufacturing the coaxial connector for the board of the related art. As a consequence, the manufacturing cost of the coaxial connector for the board and the selling cost can be lowered, and the board can be cheaply supplied to a market. 
         [0078]    The invention has been described with reference to the specific embodiment in detail, but it is apparent to those skilled in the art that various modification and alterations can be added without departing from the gist and the scope of the invention. 
         [0079]    The present invention is based on Japanese Patent Application No. 2009-255276 filed on Nov. 6, 2009, the contents of which are incorporated byway of reference.
