[0019] As shown in FIGS. 1 to 8, the connector assembly 1 includes a plug connector 100 and a receptacle connector 200. The plug connector 100 includes a plurality of plug contacts 110 and a plug housing 190 that holds the plurality of plug contacts 110. The receptacle connector 200 has a plurality of receptacle contacts 210 and a receptacle housing 290 that holds the plurality of receptacle contacts 210. The connector assembly 1 electrically contacts each plug contact 110 with each receptacle contact 210 by mating the plug connector 100 and the receptacle connector 200 with each other.

[0020] FIG. 9 is a perspective view illustrating a plug connector 100 mounted on a board 100A in the connector assembly 1 according to the first embodiment. FIG. 10 is a perspective view illustrating a receptacle connector 200 mounted on a board 200A in the connector assembly 1 according to the first embodiment. As shown in FIGS. 9 and 10, the connector assembly 1 may further include a board 100A and a board 200A. The plug connector 100 may be mountable on the board 100A. The receptacle connector 200 may be mountable on the board 200A. The board 100A may be called the plug-side board, and the board 200A may be called the receptacle-side board. Note that the connector assembly 1 does not necessarily have to include the board 100A and the board 200A. When mated, the plug connector 100 and the receptacle connector 200 face each other.

[0021] Here, for ease of explanation of the connector assembly 1, an XYZ Cartesian coordinate system is introduced. For example, a plane parallel to the plane on which the plurality of plug contacts 110 are arranged in the plug housing 190 is defined as the XY plane. The plane on which the plurality of plug contacts 110 are arranged may also be referred to as the arrangement plane. The direction in which the mated plug connector 100 and receptacle connector 200 face each other is defined as the Z-axis direction.

[0022] The plug connector 100 mated with the receptacle connector 200 is located on the +Z axis direction side of the receptacle connector 200. The receptacle connector 200 mated with the plug connector 100 is located on the -Z axis direction side of the plug connector 100. When the plug connector 100 is mounted on the board 100A, the plug connector 100 may be mounted on the -Z axis direction side of the board 100A. When the receptacle connector 200 is mounted on the board 200A, the receptacle connector 200 may be mounted on the +Z axis direction side of the board 200A. The connector assembly 1 may be a board-to-board connector that mechanically and electrically connects the boards 100A and 200A. Therefore, the connector assembly 1 may include the plug connector 100 mounted on the board 100A and the receptacle connector 200 mounted on the board 200A.

[0023] The plug housing 190 includes an insulator as a material. The plug housing 190 includes, for example, a resin as a material. Note that the plug housing 190 may include a material other than resin as long as it includes an insulator. The plug housing 190 may have, for example, a plate-like shape. When viewed from the Z-axis direction, the plug housing 190 may have, for example, a rectangular plate surface having sides extending in the X-axis direction and the Y-axis direction.

[0024] The plug housing 190 may have a shape other than a plate having a rectangular plate surface, as long as it can hold a plurality of plug contacts 110. The plug housing 190 may have a first surface 191 and a second surface 192. The second surface 192 is the surface opposite to the first surface 191. The first surface 191 is the surface on the +Z axis direction side, and the second surface 192 is the surface on the −Z axis direction side.

[0025] The plug housing 190 may have a plurality of holes 193. The holes 193 penetrate from the first surface 191 to the second surface 192. The plurality of holes 193 are formed, for example, lined up in the Y-axis direction. Of the plurality of holes 193, a predetermined number of holes 193 may be arranged lined up in the Y-axis direction. Of the plurality of holes 193, some holes 193 may be arranged lined up in a direction other than the Y-axis direction. For example, some of the holes 193 may be arranged lined up in the X-axis direction in the XY plane, or may be arranged lined up at an angle to the X-axis and Y-axis directions.

[0026] The multiple plug contacts 110 are arranged in an arrangement plane parallel to the XY plane in the plug housing 190. For example, the multiple plug contacts 110 are arranged in holes 193. As a result, the multiple plug contacts 110 are arranged side by side in the Y-axis direction.

[0027] Of the multiple plug contacts 110, a predetermined number of plug contacts 110 may be arranged side by side in the Y-axis direction. Of the multiple plug contacts 110, some plug contacts 110 may be arranged side by side in a direction other than the Y-axis direction. For example, some plug contacts 110 may be arranged side by side in the X-axis direction within the XY plane, or may be arranged side by side at an angle to the X-axis and Y-axis directions.

[0028] The receptacle housing 290 includes an insulator as a material. The receptacle housing 290 may include, for example, a resin as a material. Note that the receptacle housing 290 may include a material other than resin as long as it includes an insulator. The receptacle housing 290 has, for example, a plate-like shape. The receptacle housing 290 may have, for example, a rectangular plate surface with sides extending in the X-axis direction and the Y-axis direction when viewed from the Z-axis direction. Note that the receptacle housing 290 may have a shape other than a rectangular plate surface as long as it can hold multiple receptacle contacts 210. The receptacle housing 290 may have a first surface 291 and a second surface 292. The second surface 292 is the surface opposite the first surface 291. The first surface 291 is the surface on the +Z-axis direction, and the second surface 292 is the surface on the -Z-axis direction.

[0029] The receptacle housing 290 may have a plurality of holes 293. The holes 293 penetrate from the first surface 291 to the second surface 292. The plurality of holes 293 are formed, for example, lined up in the Y-axis direction. Of the plurality of holes 293, a predetermined number of holes 293 may be arranged lined up in the Y-axis direction. Of the plurality of holes 293, some holes 293 may be arranged lined up in a direction other than the Y-axis direction. For example, some of the holes 293 may be arranged lined up in the X-axis direction in the XY plane, or may be arranged lined up at an angle to the X-axis and Y-axis directions.

[0030] Protrusions 294 and 295 may be formed at the end of receptacle housing 290 in the Y-axis direction. Protrusion 294 is formed at the end of receptacle housing 290 in the -Y-axis direction. Protrusion 295 is formed at the end of receptacle housing 290 in the +Y-axis direction. Protrusions 294 and 295 protrude in the +Z-axis direction from first surface 291. Protrusion 294 extends in the X-axis direction along the end of receptacle housing 290 in the -Y-axis direction. Protrusion 295 extends in the X-axis direction along the end of receptacle housing 290 in the +Y-axis direction.

[0031] When the plug connector 100 and the receptacle connector 200 are mated, the plug connector 100 slides in the +X-axis direction between the protrusions 294 and 295. At this time, the protrusions 294 and 295 function as guides that allow both ends of the plug connector 100 to slide in the Y-axis direction. When the plug connector 100 and the receptacle connector 200 are mated, the plug connector 100 is disposed between the protrusions 294 and 295. The protrusions 294 and 295 sandwich the plug housing 190 of the plug connector 100 from both sides in the Y-axis direction.

[0032] The multiple receptacle contacts 210 are arranged in a plane parallel to the XY plane in the receptacle housing 290. For example, the multiple receptacle contacts 210 are arranged in holes 293. As a result, the multiple receptacle contacts 210 are arranged side by side in the Y-axis direction. Of the multiple receptacle contacts 210, a predetermined number of receptacle contacts 210 may be arranged side by side in the Y-axis direction. Of the multiple receptacle contacts 210, some receptacle contacts 210 may be arranged side by side in a direction other than the Y-axis direction. For example, some receptacle contacts 210 may be arranged side by side in the X-axis direction within the XY plane, or may be arranged side by side at an angle to the X-axis and Y-axis directions.

[0033] FIG. 11 is a perspective view illustrating the plug contacts 110 and the receptacle contacts 210 before mating in the connector assembly 1 according to the first embodiment. FIGS. 12 and 13 are side views illustrating the plug contacts 110 in the connector assembly 1 according to the first embodiment. FIG. 14 is a plan view illustrating the plug contacts 110 in the connector assembly 1 according to the first embodiment. FIG. 15 is a partial cross-sectional view illustrating the receptacle contacts 210 in the connector assembly 1 according to the first embodiment, taken along line XV-XV in FIG. 17. FIG. 16 is a side view illustrating the receptacle contacts 210 in the connector assembly 1 according to the first embodiment. FIG. 17 is a plan view illustrating the receptacle contacts 210 in the connector assembly 1 according to the first embodiment.

[0034] As shown in FIGS. 11 to 14 , the plug contact 110 includes a mounting portion 120, a protruding portion 130, and a mounting portion 140. The plug contact 110 includes a conductor as a material. The plug contact 110 may include, for example, a metal as a material. The plug contact 110 may be formed by stamping and forming a single metal plate. The metal plate is typically copper or a copper alloy. Preferably, each plug contact 110 may be plated with tin or the like before or after the stamping and bending processes.

[0035] In this embodiment, each plug contact 110 may be fixed to each hole 193 of the plug housing 190 by press-fitting, or may be fixed to each hole 193 by insert molding or with an adhesive. Also, each plug contact 110 may be fastened to each hole 193, or other methods may be used.

[0036] The mounting portion 120 is plate-shaped and has a rectangular surface when viewed from the Z-axis direction. The thickness direction of the mounting portion 120 is the Z-axis direction. Therefore, the surface of the mounting portion 120 faces the +Z-axis direction and the -Z-axis direction. The end of the mounting portion 120 on the -X-axis direction side may be exposed from the edge of the plug housing 190 on the -X-axis direction side. The mounting portion 120 may be soldered to an electrode (not shown) of the substrate 110A. The mounting portion 120 is disposed on the first surface 191 of the plug housing 190. The mounting portion 120 may be disposed in a groove formed in the first surface 191 of the plug housing 190.

[0037] The protrusion 130 is disposed between the mounting portion 120 and the mounting portion 140. Roughly speaking, the protrusion 130 is U-shaped when viewed from the Y-axis direction. The end of the U-shaped protrusion 130 on the -X-axis direction side is connected to the end of the mounting portion 120 on the +X-axis direction side. Therefore, the mounting portion 120 and the protrusion 130 are connected in an L-shape when viewed from the Y-axis direction. The protrusion 130 is curved in a U-shape so as to be convex toward the -Z-axis direction.

[0038] The protrusion 130 may include a protrusion end 131 and a protrusion root 132. The protrusion end 131 is a portion of the protrusion 130 on the -Z-axis direction side. The protrusion root 132 is a portion of the protrusion 130 on the +Z-axis direction side. The protrusion root 132 is located on the +Z-axis direction side of the protrusion end 131, and the protrusion end 131 is located on the -Z-axis direction side of the protrusion root 132. The width W1 of the protrusion end 131 in the Y-axis direction may be larger than the width W3 of the protrusion root 132 in the Y-axis direction. Note that the width W1 of the protrusion end 131 in the Y-axis direction may not be excluded from being the same width as the width W3 of the protrusion root 132 in the Y-axis direction.

[0039] The protrusion 130 has a contact surface 133 facing the -Y axis direction, a contact surface 134 facing the +Y axis direction, and a contact surface 135 facing the -X axis direction, and a contact surface 136 facing the +X axis direction. The protrusion 130 protrudes through the hole 193 of the plug housing 190 from the +Z axis direction side to the -Z axis direction side.

[0040] The mounting portion 140 is plate-shaped with a rectangular surface when viewed from the Z-axis direction. The thickness direction of the mounting portion 140 is the Z-axis direction. Therefore, the surface of the mounting portion 140 faces the +Z-axis direction and the −Z-axis direction. The −X-axis side end of the mounting portion 140 connects to the +X-axis side end of the U-shaped protrusion 130. Therefore, the mounting portion 140 and the protrusion 130 are connected in an L-shape when viewed from the Y-axis direction. The +X-axis side end of the mounting portion 140 may be exposed from the +X-axis side edge of the plug housing 190. The mounting portion 140 may or may not be soldered to an electrode (not shown) of the substrate 110A. The mounting portion 140 is disposed on the first surface 191 of the plug housing 190. The mounting portion 140 may be disposed in a groove formed in the first surface 191 of the plug housing 190.

[0041] As shown in FIGS. 11 and 15 to 17, receptacle contact 210 may include mounting portion 220, leg portion 231, leg portion 232, leg portion 233, guide portion 240, mounting portion 250, contact portion 260, and contact portion 270. Receptacle contact 210 includes a conductor as a material. Receptacle contact 210 may include, for example, a metal as a material. Receptacle contact 210 may be formed by stamping and forming a single metal plate. The metal plate is typically copper or a copper alloy. Each receptacle contact 210 may be plated with tin or the like, preferably before or after the stamping and bending processes.

[0042] In this embodiment, each receptacle contact 210 may be fixed to each hole 293 of the receptacle housing 290 by press-fitting, or may be fixed to each hole 293 by insert molding or with an adhesive. Each receptacle contact 210 may also be fastened to each hole 293, or other methods may be used.

[0043] The mounting portion 220 is disposed on the −X-axis direction side of the guide portion 240. The mounting portion 220 is plate-shaped with a Y-shaped plate surface when viewed from the Z-axis direction. The thickness direction of the mounting portion 220 is the Z-axis direction. Therefore, the plate surface of the mounting portion 220 faces the +Z-axis direction and the −Z-axis direction. The end portion of the mounting portion 220 on the −X-axis direction side may be exposed from the edge of the receptacle housing 290 on the −X-axis direction side. The mounting portion 220 may be soldered to an electrode (not shown) of the board 200A. In this way, the receptacle contact 210 includes the mounting portion 220 that can be soldered to the board 200A. The end portion of the mounting portion 220 on the +X-axis direction side is branched into a Y shape.

[0044] Legs 231 and 232 are arranged side by side in the Y-axis direction between mounting section 220 and guide section 240. Legs 231 and 232 are connected to the end of guide section 240 on the -X-axis direction side. Note that receptacle contact 210 may include at least one of leg 231 and leg 232.

[0045] The leg 231 has a portion extending in the Z-axis direction. The end of the leg 231 on the -Z-axis direction side is connected to the branched end of the mounting section 220 on the -Y-axis direction side. Therefore, the mounting section 220 and the leg 231 are connected in an L-shape when viewed from the Y-axis direction. The leg 232 has a portion extending in the Z-axis direction. The end of the leg 232 on the -Z-axis direction side is connected to the branched end of the mounting section 220 on the +Y-axis direction side. Therefore, the mounting section 220 and the leg 232 are connected in an L-shape when viewed from the Y-axis direction. Therefore, the receptacle contact 210 includes the leg 231 and the leg 232 extending in the Z-axis direction from the end of the guide section 240 on the -X-axis direction side in the X-axis direction, and the mounting section 220 connected to the leg 231 and the leg 232.

[0046] Roughly speaking, the guide portion 240 is plate-shaped with a U-shaped plate surface when viewed from the Z-axis direction. The thickness direction of the guide portion 240 is the Z-axis direction. The open part of the U-shape faces the −X-axis direction of the guide portion 240. Therefore, the guide portion 240 is U-shaped with a slit 280 extending in the X-axis direction when viewed from the Z-axis direction. The end of the leg portion 231 on the +Z-axis direction is connected to the end of the guide portion 240 on the −X-axis direction and the −Y-axis direction. Therefore, the leg portion 231 and the guide portion 240 are connected in an L-shape when viewed from the Y-axis direction. The end of the leg portion 232 on the +Z-axis direction is connected to the end of the guide portion 240 on the −X-axis direction and the +Y-axis direction. Therefore, the leg portion 232 and the guide portion 240 are connected in an L-shape when viewed from the Y-axis direction.

[0047] The space in the Y-shaped opening of mounting section 220, the space between leg sections 231 and 232, and the space in the U-shaped opening of guide section 240 are connected to form slit 280. Slit 280 extends in the X-axis direction when viewed from the Z-axis direction. In this way, guide section 240 has slit 280 that extends in the X-axis direction parallel to the arrangement surface on which multiple receptacle contacts 210 are arranged.

[0048] The leg portion 233 is disposed between the guide portion 240 and the mounting portion 250. The leg portion 233 has a portion extending in the Z-axis direction. The end portion of the leg portion 233 on the +Z-axis direction side is connected to the end portion of the guide portion 240 on the +X-axis direction side. Therefore, the guide portion 240 and the leg portion 233 are connected in an L-shape when viewed from the Y-axis direction. In this way, the receptacle contact 210 includes the leg portion 233 extending in the Z-axis direction from the end portion of the guide portion 240 on the +X-axis direction side in the X-axis direction.

[0049] The mounting portion 250 is plate-shaped with a rectangular surface when viewed from the Z-axis direction. The thickness direction of the mounting portion 250 is the Z-axis direction. Therefore, the surface of the mounting portion 250 faces the +Z-axis direction and the −Z-axis direction. The −X-axis side end of the mounting portion 250 is connected to the −Z-axis side end of the leg 233. Therefore, the leg 233 and the mounting portion 250 are connected in an L-shape when viewed from the Y-axis direction. The +X-axis side end of the mounting portion 250 may be exposed from the edge of the receptacle housing 290 on the +X-axis side. The mounting portion 250 may or may not be soldered to an electrode (not shown) of the substrate 200A.

[0050] The contact portion 260 and the contact portion 270 are connected to the end portion of the guide portion 240 on the +X-axis direction side. The contact portion 260 and the contact portion 270 are arranged on the -Z-axis direction side of the guide portion 240. The contact portion 260 is arranged on the -Y-axis direction side of the contact portion 270. The contact portion 270 is arranged on the +Y-axis direction side of the contact portion 260. The contact portion 260 and the contact portion 270 are supported by the guide portion 240 in a cantilevered manner.

[0051] The contact portion 260 includes an extension portion 261, a curved portion 262, and an extension portion 263. The contact portion 270 includes an extension portion 271, a curved portion 272, and an extension portion 273.

[0052] The extension portion 261 has a portion that extends in the Z-axis direction. The end portion of the extension portion 261 on the +Z-axis direction side is connected to the end portion of the guide portion 240 on the +X-axis direction side. Therefore, the guide portion 240 and the extension portion 261 are connected in an L-shape when viewed from the Y-axis direction. The extension portion 261 is a portion that extends in the -Z-axis direction from the end portion of the guide portion 240 on the +X-axis direction side. The extension portion 261 is positioned on the -Z-axis direction side of the guide portion 240. The end portion of the extension portion 261 on the +Z-axis direction side is located on the -Y-axis direction side of the leg portion 233.

[0053] The curved portion 262 has a portion that extends and curves in the X-axis direction. The end of the curved portion 262 on the +X-axis direction side is connected to the end of the extended portion 261 on the -Z-axis direction side. The curved portion 262 is a portion that extends in the -X-axis direction from the end of the extended portion 261 on the -Z-axis direction side, and is curved so as to be convex in the -Z-axis direction. In other words, the curved portion 262 is formed in a U-shape that opens toward the +Z-axis direction. The curved portion 262 is arranged on the -Z-axis direction side of the guide portion 240.

[0054] The extension portion 263 has a portion extending in the X-axis direction. The end portion of the extension portion 263 on the +X-axis direction side is connected to the end portion of the curved portion 262 on the −X-axis direction side. The extension portion 263 is disposed on the −Z-axis direction side of the guide portion 240.

[0055] With this configuration, the contact portion 260 functions as an elastically deformable spring piece. Specifically, the contact portion 260 functioning as a spring piece extends in a cantilever shape from the end portion of the guide portion 240 on the +X-axis direction side. The contact portion 260 may elastically deform in the Y-axis direction, with the end portion of the extension portion 261 in the +Z-axis direction as a fulcrum. In this way, the contact portion 260 includes an elastically deformable spring piece. The spring piece is a cantilever with the end portion of the extension portion 261 in the contact portion 260 in the +Z-axis direction as a fulcrum.

[0056] The extension portion 271 has a portion extending in the Z-axis direction. The end portion of the extension portion 271 on the +Z-axis direction side is connected to the end portion of the guide portion 240 on the +X-axis direction side. Therefore, the guide portion 240 and the extension portion 271 are connected in an L-shape when viewed from the Y-axis direction. The extension portion 271 is a portion that extends downward from the end portion of the guide portion 240 on the +X-axis direction side. The extension portion 271 is arranged on the -Z-axis direction side of the guide portion 240. The end portion of the extension portion 271 on the +Z-axis direction side is located on the +Y-axis direction side of the leg portion 233. Therefore, the leg portion 233 is located between the extension portion 261 and the extension portion 271 in the Y-axis direction.

[0057] The curved portion 272 has a portion that extends and curves in the X-axis direction. The end of the curved portion 272 on the +X-axis direction side is connected to the end of the extended portion 271 on the -Z-axis direction side. The curved portion 272 is a portion that extends in the -X-axis direction from the end of the extended portion 271 on the -Z-axis direction side, and is curved so as to be convex in the -Z-axis direction. In other words, the curved portion 272 is formed in a U-shape that opens toward the +Z-axis direction. The curved portion 272 is arranged on the -Z-axis direction side of the guide portion 240.

[0058] The extension portion 273 has a portion extending in the X-axis direction. The end portion of the extension portion 273 on the +X-axis direction side is connected to the end portion of the curved portion 272 on the −X-axis direction side. The extension portion 273 is disposed on the −Z-axis direction side of the guide portion 240.

[0059] With this configuration, the contact portion 270 functions as an elastically deformable spring piece. Specifically, the contact portion 270 functioning as a spring piece extends in a cantilever shape from the end portion of the guide portion 240 on the +X-axis direction side. The contact portion 270 may elastically deform in the Y-axis direction, with the end portion of the extension portion 271 in the +Z-axis direction as a fulcrum. In this way, the contact portion 270 includes an elastically deformable spring piece. The spring piece is a cantilever with the end portion of the extension portion 271 in the contact portion 270 in the +Z-axis direction as a fulcrum.

[0060] When viewed from the Z-axis direction, the contact portion 260 and the contact portion 270 extend so as to approach each other in the -X-axis direction. The extension portion 263 of the contact portion 260 may have a protrusion 264 that protrudes toward the extension portion 273 of the contact portion 270. Furthermore, the extension portion 273 of the contact portion 270 may have a protrusion 274 that protrudes toward the extension portion 263 of the contact portion 260.

[0061] As described above, the width W1 of the protruding end portion 131 in the Y-axis direction may be larger than the width W3 of the protruding base portion 132 in the Y-axis direction.

[0062] That is, (width W1 of the protruding end portion 131)>(width W3 of the protruding base portion 132).

[0063] On the other hand, the width W2 of the slit 280 of the guide portion 240 in the Y-axis direction is larger than the width W3 of the protrusion base portion 132 in the Y-axis direction.

[0064] That is, (width W2 of slit 280)>(width W3 of protruding base portion 132).

[0065] It is also possible for (width W2 of slit 280)≧(width W3 of protrusion base portion 132) to be such that protrusion base portion 132 slides while contacting the opposing edges of slit 280.

[0066] Before the connector assembly 1 is mated, the width W5 of the gap in the Y-axis direction between the protrusion 264 of the contact portion 260 and the protrusion 274 of the contact portion 270 is smaller than the width W2 of the slit 280 of the guide portion 240 in the Y-axis direction.

[0067] That is, (width W2 of slit 280)>(width W5 between protrusion 264 and protrusion 274).

[0068] Therefore, the protrusion 264 of the contact portion 260 and the protrusion 274 of the contact portion 270 are visible through the slit 280 when viewed from the Z-axis direction.

[0069] Fig. 18 is a partial cross-sectional view illustrating the plug contacts 110 and the receptacle contacts 210 after mating in the connector assembly 1 according to the first embodiment, showing a cross section taken along line XVIII-XVIII in Fig. 19. Fig. 19 is a plan view illustrating the plug contacts 110 and the receptacle contacts 210 after mating in the connector assembly 1 according to the first embodiment. As shown in Figs. 18 and 19, when the plug contacts 110 are mated with the receptacle contacts 210, the protrusions 130 of the plug contacts 110 move in the +X-axis direction along the slits 280 of the guide portions 240 of the receptacle contacts 210.

[0070] The protruding root portion 132 of the protruding portion 130 moves in the +X-axis direction along the edge of the slit 280 facing the Y-axis direction. Meanwhile, the protruding end portion 131 of the protruding portion 130 is inserted between the extension portion 263 of the contact portion 260 and the extension portion 73 of the contact portion 270. The contact portions 260 and 270 elastically deform so as to expand on both sides in the Y-axis direction as the protruding end portion 131 moves in the +X-axis direction. Thus, the contact portions 260 and 270 include spring pieces that elastically deform as the plug contacts 110 move in the +X-axis direction along the slit 280. The two spring pieces contact each plug contact 110 that has moved to a predetermined mating position in the slit 280 due to a spring restoring force. The predetermined mating position may be, for example, a position where the protruding portion 264 of the contact portion 260 and the protruding portion 274 of the contact portion 270 are positioned at the center of the U-shape of the protruding portion 130.

[0071] In this way, each plug contact 110 that has moved to the mating position in the slit 280 is inserted between the two spring pieces of the contact portion 260 and the contact portion 270. Note that the receptacle contact 210 may have at least one spring piece of the contact portion 260 or the contact portion 270 contact each plug contact 110 that has moved to the mating position in the slit 280 by the spring restoring force.

[0072] Next, a description will be given of the mating operation of the connector assembly 1. Figures 20 and 21 are partial cross-sectional views illustrating the mating operation of the plug contacts 110 and the receptacle contacts 210 in the connector assembly 1 according to the first embodiment.

[0073] To mate the plug connector 100 with the receptacle connector 200, the plug connector 100 and the receptacle connector 200 are placed opposite each other in the Z-axis direction.

[0074] Next, the plug connector 100 and the receptacle connector 200 are brought closer together. For example, the plug connector 100 is moved in the −Z-axis direction toward the receptacle connector 200. Alternatively, the receptacle connector 200 may be moved in the +Z-axis direction toward the plug connector 100.

[0075] Next, as shown in FIG. 20, when the plug connector 100 and the receptacle connector 200 are brought closer together, they are brought closer together so that the protruding portions 130 of the plug contacts 110 are positioned above the mounting portions 220 of the receptacle contacts 210.

[0076] Next, as shown in Fig. 21, protrusion 130 of plug contact 110 is moved in the +X-axis direction. Protrusion 130 passes through slit 280 between leg portions 231 and 232, and moves through slit 280 in guide portion 240 in the +X-axis direction. In this manner, plug connector 100 can be mated with receptacle connector 200, as shown in Figs. 18 and 19. When plug connector 100 is to be removed from receptacle connector 200, the mating procedure is reversed.

[0077] Next, the effects of the connector assembly 1 of this embodiment will be described. In the connector assembly 1 of this embodiment, the receptacle contact 210 includes a guide portion 240 having a slit 280 extending in the X-axis direction, and contact portions 260 and 270 that are arranged in the -Z-axis direction relative to the guide portion 240. The guide portion 240 functions as a guide that moves the plug contact 110 in the X-axis direction along the slit 280. Meanwhile, the contact portions 260 and 270 function as spring pieces that elastically deform as the plug contact 110 moves, thereby contacting the plug contact 110.

[0078] As described above, the connector assembly 1 has a two-stage structure that separates the function of guiding the movement of the plug contacts 110 and the function of making contact with the plug contacts 110 when mating the plug contacts 110 and the receptacle contacts 210. Therefore, deterioration such as peeling of plating caused by contact between the plug contacts 110 and the receptacle contacts 210 during the mating operation can be shared between the guide portion 240 and the protruding base portion 132 and the contact portion 260, the contact portion 270, and the protruding end portion 131. This makes it possible to suppress deterioration of each component, thereby improving contact reliability.

[0079] Furthermore, the elastic strength of the guide portion 240 and the elastic strength of the contact portions 260 and 270 can be controlled separately. Therefore, the guide portion 240 can be formed to be less likely to deform so that it functions as a guide, and the contact portions 260 and 270 can be formed to be more easily deformed so that they function as contact portions. In other words, it is sufficient for the contact portions 260 and 270 to have a minimum spring restoring force to contact the plug contacts 110. Therefore, the contact portions 260 and 270 can reduce friction with the plug contacts 110, thereby suppressing deterioration and improving contact reliability.

[0080] In contrast, in a connector assembly such as that described in Patent Document 1, the contact points between the plug contacts and receptacle contacts during mating also serve as guides for the movement of the plug contacts and receptacle contacts. As a result, deterioration such as peeling of plating caused by contact during the mating operation is concentrated in one area. This accelerates deterioration of each component, making it difficult to improve contact reliability.

[0081] <Embodiment 2> Next, a connector assembly according to a second embodiment will be described. In the connector assembly of this embodiment, a protrusion that narrows the width of the slit 280 is formed in the guide portion 240 near the mating position of the slit 280. Fig. 22 is a perspective view illustrating a receptacle contact 210 in the connector assembly 1 according to the second embodiment. Fig. 23 is a plan view illustrating a receptacle contact 210 in the connector assembly 2 according to the second embodiment.

[0082] 22 and 23, guide portion 240 is formed with protrusions 241 and 242 near the fitting position of slit 280, which narrow the width of slit 280 in the Y-axis direction. Protrusion 241 protrudes in the +Y-axis direction from the edge of slit 280 on the -Y-axis direction side. Protrusion 242 protrudes in the -Y-axis direction from the edge of slit 280 on the +Y-axis direction side. Therefore, width W4 between protrusions 241 and 242 in the Y-axis direction is narrower than width W2 of slit 280 in the Y-axis direction.

[0083] That is, (width W2 of slit 280)>(width W4 between protrusions 241 and 242).

[0084] The width W3 of the protrusion base 132 of the protrusion 130 in the Y-axis direction is larger than the width W4 of the distance between the protrusions 241 and 242 in the Y-axis direction.

[0085] That is, (width W3 of protrusion base portion 132)>(width W4 between protrusions 241 and 242).

[0086] Therefore, when the plug contact 110 slides in the +X-axis direction along the slit 280, the protruding root portion 132 of the protruding portion 130 moves to the mating position, climbing over the protruding portions 241 and 242. Other configurations and operations are the same as those of the first embodiment.

[0087] Next, the effects of this embodiment will be described. The connector assembly 1 of this embodiment has protrusions 241 and 242 in the guide portion 240 that narrow the width of the slit 280. Therefore, when mating the plug contacts 110 and the receptacle contacts 210, the protruding root portions 132 of the plug contacts 110 climb over the protrusions 241 and 242 of the receptacle contacts 210 to achieve mating. This provides a tactile sensation, such as a click, upon mating, improving contact reliability.

[0088] In contrast, the connector assembly described in Patent Document 1 does not have protrusions at the portions where the plug contacts and receptacle contacts come into contact upon mating. This makes it difficult to get a tactile sense of mating during slide mating, raising concerns that the connector may end up in a partially mated state. Furthermore, if protrusions were formed at the portions where the plug contacts and receptacle contacts come into contact upon mating in Patent Document 1, there is a risk that the portions that function as spring pieces to make contact may be excessively deformed.

[0089] In the connector assembly 1 of this embodiment, the protrusions 241 and 242 are formed on the guide portion 240, which functions as a guide for the movement of the plug contacts 110. This prevents the contact portions 260 and 270 from excessively deforming. Furthermore, in this embodiment, the elastic strength of the guide portion 240 and the elastic strength of the contact portions 260 and 270 can be controlled independently. Therefore, the elastic strength of the protrusions 241 and 242 of the guide portion 240 can be adjusted so that they provide a sufficient clicking sensation. Meanwhile, the contact portions 260 and 270 only need to have a minimum spring restoring force to contact the plug contacts 110. Therefore, both the clicking sensation and contact reliability can be achieved. Other advantages of the second embodiment are included in the description of the first embodiment.

[0090] <Embodiment 3> Next, a connector assembly 1 according to a third embodiment will be described. In the connector assembly 1 of this embodiment, the contact portions 260 and 270 that function as spring pieces in the receptacle contact 210 extend in a cantilevered manner from the leg portion 233. Fig. 24 is a perspective view illustrating the receptacle contact 210 in the connector assembly 1 according to the third embodiment. As shown in Fig. 24, the leg portion 233 extends in the -Z axis direction from the end portion of the guide portion 240 on the +X axis direction side.

[0091] The contact portion 260 is connected to the end portion on the −Y-axis direction side of the leg portion 233. The contact portion 260 extends in the −X-axis direction from the end portion on the −Y-axis direction side of the leg portion 233. The contact portion 260 includes an extension portion 261, a curved portion 262, and an extension portion 263.

[0092] The extension portion 261 has a portion extending in the X-axis direction. The end portion of the extension portion 261 on the +X-axis direction side is connected to the end portion of the leg portion 233 on the -Y-axis direction side. The curved portion 262 extends in the X-axis direction while curved.

The extension portion 263 has a portion extending in the X-axis direction. The end portion of the extension portion 263 on the +X-axis direction side is connected to the end portion of the curved portion 262 on the -X-axis direction side.

[0093] The extension portion 271 has a portion extending in the X-axis direction. The end portion of the extension portion 271 on the +X-axis direction side is connected to the end portion of the leg portion 233 on the +Y-axis direction side. The curved portion 272 extends in the X-axis direction while curved. The end portion of the curved portion 272 on the +X-axis direction side is connected to the end portion of the extension portion 271 on the -X-axis direction side. The extension portion 273 has a portion extending in the X-axis direction. The end portion of the extension portion 273 on the +X-axis direction side is connected to the end portion of the curved portion 272 on the -X-axis direction side.

[0094] In this embodiment, the contact portions 260 and 270, which function as spring pieces, are connected to the ends of the legs 233 in the Y-axis direction. This facilitates swinging in the Y-axis direction. Therefore, the elastic deformation of the contact portions 260 and 270 in the Y-axis direction can be easily controlled. Other configurations, operations, and effects of the third embodiment are included in the descriptions of the first and second embodiments.

[0095] <Embodiment 4> Next, a connector assembly 1 according to a fourth embodiment will be described. In this embodiment, contact portions 260 and 270 functioning as spring pieces in receptacle contact 210 extend in a cantilevered manner from the end portions on the -Y axis direction side and the +Y axis direction side of guide portion 240. Figure 25 is a perspective view illustrating receptacle contact 210 in connector assembly 1 according to the fourth embodiment.

[0096] As shown in FIG. 25 , the contact portion 260 is connected to the end of the guide portion 240 on the −Y-axis direction side. The contact portion 260 includes an extending portion 261, a curved portion 262, and an extending portion 263. The extending portion 261 has a portion extending in the Z-axis direction. The end of the extending portion 261 on the +Z-axis direction side is connected to the end of the guide portion 240 on the −Y-axis direction side. The curved portion 262 extends in the Y-axis direction while curved. The end of the curved portion 262 on the −Y-axis direction side is connected to the end of the extending portion 261 on the −Z-axis direction side. The extending portion 263 has a portion extending in the Y-axis direction. The end of the extending portion 263 on the −Y-axis direction is connected to the end of the curved portion 262 on the +Y-axis direction side.

[0097] The contact portion 270 is connected to the end portion on the +Y-axis direction side of the guide portion 240. The contact portion 270 includes an extending portion 271, a curved portion 272, and an extending portion 273. The extending portion 271 has a portion extending in the Z-axis direction. The end portion on the +Z-axis direction of the extending portion 271 is connected to the end portion on the +Y-axis direction of the guide portion 240. The curved portion 272 extends in the Y-axis direction while curved. The end portion on the +Y-axis direction of the curved portion 272 is connected to the end portion on the -Z-axis direction of the extending portion 271. The extending portion 273 has a portion extending in the Y-axis direction. The end portion on the +Y-axis side of the extending portion 273 is connected to the end portion on the -Y-axis direction of the curved portion 272.

[0098] In this embodiment, the contact portions 260 and 270, which function as spring pieces, are connected to the ends of the guide portion 240 in the Y-axis direction. This facilitates swinging in the Y-axis direction. Therefore, the elastic deformation of the contact portions 260 and 270 in the Y-axis direction can be easily controlled. Other configurations, operations, and effects of the fourth embodiment are included in the descriptions of the first to third embodiments.

[0099] <Embodiment 5> Next, a connector assembly 1 according to a fifth embodiment will be described. In the connector assembly 1 of this embodiment, contact portions 260 and 270 functioning as spring pieces in the receptacle contact 210 extend in a cantilevered manner from the leg portions 231 and 232, respectively. Fig. 26 is a perspective view illustrating the receptacle contact 210 in the connector assembly 1 according to the fifth embodiment. As shown in Fig. 26, the leg portions 231 and 232 extend in the -Z axis direction from the end of the guide portion 240 on the -X axis direction side.

[0100] The contact portion 260 is connected to the end portion on the −Y-axis direction side of the leg portion 231. The contact portion 260 extends in the +X-axis direction from the end portion on the −Y-axis direction side of the leg portion 231. The contact portion 260 includes an extension portion 261, a curved portion 262, and an extension portion 263.

[0101] The extension portion 261 has a portion extending in the X-axis direction.

The extension portion 273 has a portion extending in the X-axis direction. The end portion of the extension portion 273 on the -X-axis side is connected to the end portion of the curved portion 272 on the +X-axis direction side.

[0103] In this embodiment, contact portions 260 and 270, which function as spring pieces, are connected to the Y-axis direction ends of leg portions 231 and 232, respectively. This facilitates swinging in the Y-axis direction. Therefore, elastic deformation of contact portions 260 and 270 in the Y-axis direction can be easily controlled. Other configurations, operations, and effects of embodiment 5 are included in the descriptions of embodiments 1 to 4.
