To do. FIG. 1 is a perspective view showing an appearance of a terminal fitting according to this embodiment. In the drawings (FIGS. 1 and 2) showing the configuration of the terminal fitting according to this embodiment, an XYZ orthogonal coordinate system is set, and the positional relationship of each member will be described with reference to this orthogonal coordinate system. . The Z axis is set in a direction orthogonal to the suction surface 4 so that the X axis is parallel to the longitudinal direction of the suction surface 4 to be described later, the Y axis is parallel to the short direction of the suction surface 4. ing. Further, the position of the housing (not shown) as the second planar member with respect to the terminal fitting 2 is in the + Z direction, and the position of the printed board (not shown) as the first planar member with respect to the terminal fitting 2 is in the −Z direction. Is set to

端子金具２は、図１に示すように、端子金具２をプリント基板上へ搬送する際に使用される吸着ノズル（図示せず）を吸着させる吸着面４を備えている。端子金具２は、吸着面４のＹ方向における両側部からプリント基板側（−Ｚ方向側）に向けて折り曲げて形成される保護壁８ａ，８ｂを備えている。 As shown in FIG. 1, the terminal fitting 2 includes a suction surface 4 that sucks a suction nozzle (not shown) used when the terminal fitting 2 is transported onto a printed board. The terminal fitting 2 includes protective walls 8a and 8b that are formed by being bent from both sides in the Y direction of the suction surface 4 toward the printed circuit board side (−Z direction side).

図２は、この実施の形態に係る端子金具２のＸＺ断面を＋Ｙ方向側から視た斜視図である。端子金具２は、図１及び図２に示すように、保護壁８ａのプリント基板側（−Ｚ方向側）の端部に配置され、プリント基板に例えば半田付け等により実装される実装部１０ａ，１０ｂと、保護壁８ｂのプリント基板側（−Ｚ方向側）の端部に配置され、プリント基板に例えば半田付け等により実装される実装部１０ｃ，１０ｄとを備えている。また、端子金具２は、吸着面４の＋Ｘ方向側の端部からプリント基板側（−Ｚ方向側）に折り曲げられ、更に−Ｘ方向側に向けて折り曲げて形成されるバネ部１２を備えている。 FIG. 2 is a perspective view of the XZ section of the terminal fitting 2 according to this embodiment as viewed from the + Y direction side. As shown in FIGS. 1 and 2, the terminal fitting 2 is disposed at the end of the protective wall 8a on the printed board side (−Z direction side), and is mounted on the printed board by, for example, soldering or the like. 10b and mounting portions 10c and 10d which are disposed on the printed board side (−Z direction side) end of the protective wall 8b and are mounted on the printed board by, for example, soldering. The terminal fitting 2 includes a spring portion 12 that is bent from the + X direction side end of the suction surface 4 to the printed circuit board side (−Z direction side) and further bent toward the −X direction side. Yes.

端子金具２は、吸着面４の−Ｘ方向側の端部に切欠き部６を有し、切欠き部６には、接触部１６が配置されている。接触部１６は、−Ｚ方向側に開いたＵ字形状であって、筐体に接触する接点部１４を有している。接点部１４は、接触部１６の筐体側（＋Ｚ方向側）に位置し、吸着面４に対して筐体側（＋Ｚ方向側）に突出している。また、接触部１６の端部１７，１８は、プリント基板側（−Ｚ方向側）に位置し、接触部１６の−Ｘ方向側の端部１７は、＋Ｘ方向側に向けて折り曲げられている。また、接触部１６の＋Ｘ方向側の端部１８は、＋Ｘ方向側に向けて折り曲げられ、バネ部１２の端部と連結されている。したがって、プリント基板に実装された端子金具２の接触部１６に筐体が押接されると、バネ部１２の弾性により接点部１４が−Ｚ方向に移動する。 The terminal fitting 2 has a notch 6 at the end of the suction surface 4 on the −X direction side, and a contact 16 is disposed in the notch 6. The contact portion 16 has a U shape that is open on the −Z direction side, and has a contact portion 14 that contacts the housing. The contact portion 14 is located on the housing side (+ Z direction side) of the contact portion 16 and protrudes toward the housing side (+ Z direction side) with respect to the suction surface 4.

That is, even when the suction surface 4 receives an external force from the suction nozzle or the like, the protective walls 8a and 8b prevent the suction surface 4 from being deformed. Moreover, since the contact part 16 is arrange | positioned at the notch part 6, even if the contact part 16 receives the external force from directions other than -Z direction, the adsorption | suction surface 4 and the protective walls 8a and 8b are the contact parts 16. To prevent deformation.
