An outer conductor lead portion 44 extending downward is provided at the lower edge of each side wall portion 42. The outer conductor lead 44 is connected to a ground circuit (not shown) of the circuit board. Thereby, the external noise absorbed by the outer conductor terminal 40 can be released to the ground circuit of the circuit board, and the inner conductor terminal 50 can be prevented from being affected by the external noise.

  Now, as shown in FIG. 5, the inner conductor terminal 50 has a terminal body 51 formed by bending a rod-shaped core material into an L shape. The terminal main body 51 includes a bent portion 52 bent at a substantially right angle, a terminal connecting portion 53 extending forward from the bent portion 52, and a board connecting portion 54 extending downward from the bent portion 52. . The bent portion 52 is formed by pressing a rod-shaped core material to form a predetermined shape and then bending it. For this reason, the structure of the inner conductor terminal 50 can be simplified.

  The terminal connection portion 53 has a contact portion 55 having a round pin shape, and a tip portion of the contact portion 55 is tapered. At the rear end of the contact portion 55, a press-fit portion 56 formed to be slightly wider than the contact portion 55 is connected. On the other hand, the board connecting portion 54 has an inner conductor lead portion 60 having a square pin shape, and a tip portion of the inner conductor lead portion 60 is tapered. Above the inner conductor lead portion 60, a widened portion 61 is formed which is formed wider than the inner conductor lead portion 60 on both sides in the width direction. The widened portion 61 has the largest width dimension in the terminal body 51.

  The lower end of the bent portion 52 is connected to the upper end of the widened portion 61 with the same width. That is, like the widened portion 61, the bent portion 52 has the largest width dimension in the terminal main body 51, so that the width dimension of the terminal main body 51 is not increased between both side edges in the width direction. Formed). A plurality of recesses 62 cut out in the front-rear direction are provided on both side surfaces of the widened portion 61 in the width direction. A pair of each recess 62 is arranged on both sides in the width direction of the widened portion 61.

  The press-fit portion 56 has a flat plate shape as a whole, and a plurality of press-fit protrusions 57 are provided on both side edges of the press-fit portion 56 in the width direction. A pair of the press-fitting protrusions 57 are arranged side by side in the front-rear direction on both sides in the width direction of the press-fit portion 56. On the side surface of each press-fitting protrusion 57, a biting surface 58 is provided that protrudes laterally toward the rear. Similarly, on the side surface of each press-fitting projection 57, a locking surface 59 having a slightly standing shape is continuous behind the biting surface 58. In addition, a jig contact portion 63 described later is connected to the rear end of the press-fit portion 56, and the jig contact portion 63 is configured to be wider than the press-fit portion 56.

  A jig insertion space S formed by cutting out in a form penetrating in the plate thickness direction is provided at the center in the width direction of the bent portion 52. The jig insertion space S includes a jig contact part 63 that constitutes the front end of the bending part 52, a pair of restricting parts 64 and 64 disposed on both sides in the width direction of the jig insertion space S, and a widened part 61. It is comprised as a space enclosed by the upper end part of. A surface constituting the inner wall of the jig insertion space S in the jig abutting portion 63 is a pressing surface 65. As a result, the jig J inserted into the jig insertion space S comes into contact with the pressing surface 65 at the jig contact portion 63.

  Thus, since the jig insertion space S and the jig contact portion 63 are provided within the range of the width dimension of the bending portion 52 without increasing the width dimension of the bending portion 52, the inner conductor terminal 50 is provided. The size is reduced. Accordingly, the dielectric 30 to which the inner conductor terminal 50 is attached is also downsized, and the inner conductor terminal 50 and the outer conductor terminal 40 can be arranged close to each other. Further, when the jig J is inserted into the jig insertion space S, it is not necessary to avoid the jig J coming into contact with the bent portion 52, and the tip of the jig J is pressed against the pressing surface 65 of the jig abutting portion 63. It becomes easy to make it contact.

  The pressing surface 65 is disposed at the center in the width direction of the bent portion 52, and is a flat surface orthogonal to the front-rear direction (the press-fit direction of the press-fit portion 56 with respect to the terminal holding portion 31) as shown in FIGS. Yes. For this reason, it is easy to press the pressing surface 65 with the tip of the jig J, so that the press-fit portion 56 can be press-fitted into the holding hole 33 of the terminal holding portion 31 in a balanced manner. On the other hand, the surface constituting the inner wall of the jig insertion space S in the widened portion 61 is a flat surface that is parallel to the surface of the circuit board.

  Further, since the terminal connection portion 53, the press-fit portion 56, and the bending portion 52 are arranged in a straight line along the front-rear direction, the pressing force by the jig J is directly transmitted to both the terminal connection portion 53 and the press-fit portion 56. be able to. Therefore, it becomes easy to press-fit the press-fit portion 56 straight into the terminal holding portion 31. Furthermore, since the pressing surface 65 of the jig contact portion 63 has the same height as the plate thickness of the terminal body 51, the pressing surface 65 can be formed in the entire region of the terminal body 51 in the height direction. It is easy to press the pressing surface 65 with the tip of the jig J.

  The upper and lower corners of the opposing surface of each restricting portion 64 are chamfered chamfered portions 66, which contribute to the improvement of the impedance characteristics of the bent portion 52 and the jig J as a jig. It also functions as a guide for guiding to the insertion space S. As shown in FIGS. 7 and 8, the distance between the restricting portions 64, 64 is the same as or slightly larger than the width of the jig J. As a result, when the inner conductor terminal 50 is press-fitted into the dielectric 30 by the jig J, the jig J fitted to the jig abutting portion 63 is accommodated between the restricting portions 64 and 64 with a slight clearance. Therefore, the deflection of the jig J in the width direction is restricted.

  The present embodiment is configured as described above, and its operation will be described subsequently. First, an operation for mounting the inner conductor terminal 50 to the dielectric 30 will be described. As shown in FIG. 5, the terminal connection portion 53 of the inner conductor terminal 50 is disposed behind the terminal holding portion 31 of the dielectric 30, and the jig J is inserted into the jig insertion space S. The tip of the jig J is brought into contact with the pressing surface 65 of the jig contact portion 63, and the pushing by the jig J is started. When the tip of the jig J enters the holding hole 33 of the terminal holding portion 31 and the tip of the press-fit portion 56 reaches the inlet of the holding hole 33, press-fitting of the press-fit portion 56 into the terminal holding portion 31 is started. This press-fitting is performed while the biting surface 58 of the press-fitting projection 57 is biting into the inner wall of the holding hole 33.

  Meanwhile, as shown in FIG. 10, a pair of left and right front stop protrusions 36, 36 are provided on the surface of the dielectric 30 that faces the widened portion 61. As shown in FIG. 9, when the press-fit portion 56 is pushed to the completion position, the front stop protrusion 36 comes into contact with the front surface of the widened portion 61 so that the press-fit portion 56 cannot be pushed any further. Thus, the press-fitting part 56 is press-fitted to the completion position, and the press-fitting work is completed. Here, when a force is applied rearward to the inner conductor terminal 50, as shown in FIG. 8, the locking surface 59 bites into the inner wall of the holding hole 33 and is locked from the front, so that the inner conductor terminal 50 is It is held in a retaining state. Next, the dielectric 30 is covered with the outer conductor terminal 40, and the outer conductor terminal 40 is mounted on the mounting portion 24 of the housing 20 in this state, whereby the board connector 10 is completed.

  As described above, in the present embodiment, the jig abutting portion is not provided so as to protrude outward in the width direction from both side edges of the terminal body 51 in the width direction, but the range of the maximum width dimension in the width direction of the terminal body 51. Since the jig contact portion 63 is provided therein, the jig contact portion 63 and the jig insertion space S can be formed without increasing the size of the terminal body 51 in the width direction. As a result, the dielectric 30 to which the inner conductor terminal 50 is attached can also be reduced in the width direction, and the outer conductor terminal 40 and the inner conductor terminal 50 that cover the dielectric 30 are arranged close to each other in the width direction. Can do. Furthermore, the housing 20 to which the inner conductor terminal 50, the dielectric 30 and the outer conductor terminal 40 are mounted can also be reduced in the width direction, so that the board connector 10 can be reduced in the width direction. it can.

  Further, since the jig contact portion 63 is provided in the bending portion 52, when the jig J is inserted into the jig insertion space S, it is not necessary to insert the jig J carefully so as not to contact the bending portion 52. The insertion work becomes easy. Furthermore, since the pair of restricting portions 64, 64 are provided on both sides in the width direction of the jig insertion space S, the jig J inserted into the jig insertion space S can be restricted from moving in the width direction. Therefore, the press-fitting work by the jig J can be easily performed. Further, since the pressing surface 65 with which the tip of the jig J contacts is configured as a flat surface, the tip of the jig J is prevented from sliding on the pressing surface 65 and the pressing surface 65 is reliably moved forward by the jig J. Can be pushed in. In addition to these, the jig insertion space S is notched in a form penetrating in the plate thickness direction of the bent portion 52, and the jig contact portion 63 is formed in the entire area of the terminal body 51 in the plate thickness direction. The jig J can be easily brought into contact with the jig contact portion 63.

  In addition, since the jig contact portion 63 is provided at the center in the width direction of the bent portion 52, the press-fit portion 56 can be press-fit into the terminal holding portion 31 with a good balance. Furthermore, since the terminal connection portion 53, the press-fit portion 56, and the jig contact portion 63 are arranged so as to be aligned in a straight line in the press-fit direction of the jig J, the pressing force by the jig J is applied to the terminal connection portion 53 and the press-fit portion. 56 can be transmitted directly to both. Therefore, it becomes easy to press-fit the press-fit portion 56 straight into the terminal holding portion 31.
