  One embodiment will be described with reference to FIGS. For convenience of explanation, this embodiment is referred to as a first embodiment.

  FIG. 1 is a perspective view of a plate-like cable connector 101. The plate-like cable connector 101 is disposed on the substrate 201 (see FIG. 3), and the hold-down portion 102A is fixed by reflow soldering or the like. The plate-like cable connector 101 can be fitted with an FPC cable 301 (see FIG. 2) as a plate-like cable. The flexible wiring 302 (see FIG. 2) in the FPC cable 301 and the printed wiring 202 on the substrate 201 (see FIG. 3). Are electrically connected to each other.

  FIG. 2 is a perspective view of the FPC cable 301. The FPC cable 301 has a cable body 303. The cable body 303 is formed of a flexible material and has a plate shape. A wide portion 303 </ b> A is formed at the end of the cable body 303. The wide portion 303 </ b> A protrudes outward at both widthwise portions of the cable body 303. A plurality of flexible wirings 302 are formed in the cable body 303. These flexible wirings 302 are arranged at substantially equal intervals in the width direction of the cable main body 303, and all extend in the length direction of the cable main body 303. A rectangular terminal portion 302 </ b> A is provided at the end of each flexible wiring 302. The terminal portion 302A is disposed in or near the wide portion 303A and is exposed on one surface (first surface 303B) of the cable body 303. The first surface 303B corresponds to the “surface area of the cable body” in the claims. 2 shows the other surface (second surface 303C) of the cable body 303, and the first surface 303B is not visible in FIG.

  A reinforcing plate 304 is attached to the end region of the other surface (second surface 303C) of the cable body 303. The reinforcing plate 304 is harder than the cable body 303 and is formed of a plate-like material that is equal to or thicker than the cable body 303. The reinforcing plate 304 looks like a wide convex shape that combines a part of the cable body 303 and the wide portion 303A in plan view. The reinforcing plate 304 includes a wing portion 304A. The wing portion 304A protrudes on both sides in the width direction with respect to the cable body 303, and appears to coincide with the wide portion 303A of the cable body 303 in a plan view. By forming the reinforcing plate 304 with a conductive metal plate, it is possible to improve the shielding performance of this portion against external electromagnetic noise.

  FIG. 3 is a perspective view of the plate-like cable connector 101 with the FPC cable 301 attached. The housing 102 of the plate-like cable connector 101 has a flat and substantially rectangular parallelepiped shape, and appears to be substantially rectangular in plan view and is hollow. The housing 102 forms an opening that extends from the upper surface to an end surface that can be seen below the plane of FIG. 3 and the other end surface that is on the opposite side. When attaching the FPC cable 301 to the plate-like cable connector 101, the operator positions the reinforcing plate 304 of the FPC cable 301 on the end surface side that can be seen on the lower side of FIG. 3 and passes the FPC cable 301 to the opening of the housing 102. Then, the FPC cable 301 is pulled in the extending direction of the cable body 303 (the direction of the arrow K shown in FIG. 3). As a result, the reinforcing plate 304 slides into the housing 102 and is caught by the first retaining portion 103 provided in the housing 102, and the second retaining portion 104 provided in the housing 102 and the contact 105. It is sandwiched between and fixed. At this time, the contact 105 contacts the terminal portion 302A (see FIG. 2) of the FPC cable 301, and the flexible wiring 302 (see FIG. 2) in the FPC cable 301 and the printed wiring 202 on the substrate 201 are electrically connected. As a result, electrical signals can be transmitted. When the FPC cable 301 is removed from the plate-like cable connector 101, the operator pushes the reinforcing plate 304 to the end face side (the direction opposite to the arrow K) that can be seen on the lower side in FIG.

  FIG. 4 is a perspective view of the plate-like cable connector 101 viewed from an angle different from that in FIG. FIG. 5 is a perspective view of the plate-like cable connector 101 on the side different from the side visible in FIG. FIG. 6 is a plan view of the plate-like cable connector 101. FIG. 7 is a bottom view of the plate-like cable connector 101. FIG. 8 is a front view of the plate-like cable connector 101. FIG. 9 is a view taken in the direction of arrow P in FIG. FIG. 10 is a rear view of the plate-like cable connector 101. Details of the structure of the plate cable connector 101 will be described with reference to FIGS. 1, 4, 5, 6, 7, 8, 9 and 10.

  The plate-like cable connector 101 has a housing 102 and a contact 105. The housing 102 includes a hold-down part 102A and a resin part 102B. The hold-down portion 102A is formed by pressing a sheet metal. The bent portion 102Aa of the hold-down portion 102A is rounded so that the FPC cable 301 can be easily introduced. The resin part 102B is formed by embedding part of the contacts 105 arranged in parallel with resin and integrally molding with the hold-down part 102A. As another embodiment, resin molding is performed using a hold-down portion formed using sheet metal in a shape different from the hold-down portion 102A having the shape shown in FIG. As a result of combining the above, the housing 102 shown in FIG.

  The housing 102 has a top surface portion 111, a first side portion 112, a second side portion 113, and a bottom surface portion 114, and is hollow. Application of solder or adhesive for fixing the plate-like cable connector 101 to the substrate 201 (see FIG. 3) is an area formed by the hold-down portion 102A on the bottom surface side of the bottom surface portion 114 (hatched in FIG. 7). (Region indicated by). When the plate-like cable connector 101 is fixed to the substrate 201, the upper surface portion 111 faces substantially parallel to the substrate 201. At this time, the first side portion 112 and the second side portion 113 intersect with the substrate 201 from each of two opposing long sides 111A and 111B (shown only in FIG. 1) in the upper surface portion 111 (preferably Extends in a direction substantially perpendicular to each other (see FIG. 3).

  The housing 102 is provided with an upper surface opening 121, a front end side opening 122, and an extension side opening 123.

  The upper surface opening 121 is formed in a shape that opens to the upper surface 111 and allows the plate-like cable connector 101 to pass in the vertical direction. That is, the width dimension of the upper surface opening 121 is at least equal to or larger than the width dimension of the cable body 303 (see FIGS. 3 and 11).

  The distal end side opening portion 122 is continuous with the upper surface opening portion 121 and opens to the first side portion 112. The front end side opening 122 is opened in a shape that allows the sliding movement of the reinforcing plate 304 to move substantially parallel to the bottom surface portion 114 in the direction connecting the first side portion 112 and the second side portion 113. That is, the width dimension of the front end side opening 122 is equal to or larger than the width dimension of the reinforcing plate 304, and the height dimension of the front end side opening 122 is equal to or larger than the thickness of the reinforcing plate 304. Further, the peripheral portion 122A of the distal end side opening 122 is chamfered so that an operator can easily introduce the reinforcing plate 304 into the distal end side opening 122.

  The extension side opening 123 is connected to the upper surface opening 121 and opens to the second side 113. The extension-side opening 123 has a shape that allows the cable body 303 to slide and move the cable body 303 substantially parallel to the bottom surface part 114 in the direction connecting the first side part 112 and the second side part 113. It is open. That is, the width dimension of the extension side opening 123 is equal to or greater than the width dimension of the cable body 303, and the height dimension of the extension side opening 123 is equal to or greater than the thickness of the cable body 303.

  A central opening 124 and a side opening 125 are formed in the bottom surface portion 114 of the housing 102. Each of the central opening 124 and the side opening 125 is formed as a response to an undercut when the resin is integrally formed. During resin molding, a reinforcing body support 127 is formed between the central opening 124 and the side opening 125. The reinforcing body support portion 127 has a long length extending in a direction connecting the first side portion 112 side and the second side portion 113 side, and is flush with the upper surface of the bottom surface portion 114.

  The contacts 105 are arranged on the inner bottom side of the housing 102, and a plurality of contacts 105 are arranged in the width direction of the housing 102. In each of the contacts 105, a part of the middle of the contact 105 (portion indicated by reference numeral 105A in FIG. 6) is embedded in a region on the first side portion 112 side of the resin portion 102B. The number and position of the contacts 105 correspond to the number and position of the terminal portions 302A provided in the FPC cable 301. The contact 105 protrudes from the bottom surface portion 114 formed by the resin portion 102B to the first side portion 112 side and is connected to the substrate 201, and protrudes above the bottom surface portion 114 and toward the second side portion 113 side. And an elastic deformation portion 105C located above the central opening 124. The elastic deformation portion 105C comes into contact with the terminal portion 302A (see FIG. 2) of the FPC cable 301 positioned in the housing 102 by sliding the reinforcing plate 304 from the distal end side opening portion 122.

  Please refer to FIG. 1, FIG. 2, FIG. 3, FIG. The first retaining portion 103 provided in the housing 102 is located in the housing 102 and end face 304B on the second side 113 side of the wing portion 304A of the reinforcing plate 304 that is to move further to the second side 113 side therefrom. And the reinforcing plate 304 is prevented from falling off from the extended opening 123.

  The second retaining portion 104 provided in the housing 102 is provided closer to the first side portion 112 than the first retaining portion 103 and extends in the width direction of the plate-like cable connector 101 in parallel with the upper surface portion 111. It protrudes toward the inner side of the connector 101 and is flush with the upper surface of the upper surface portion 111. The second retaining portion 104 interferes with the upper surface 304C of the reinforcing plate 304 located in the housing 102, and prevents the reinforcing plate 304 from moving toward the upper surface portion 111 side.

  A guide mark 126 is provided on the upper surface of the bottom surface portion 114 of the housing 102. The guide mark 126 is used for visually confirming the positioning of the reinforcing plate 304. The guide mark 126 is located on the first side 112 side of the housing 102 with respect to the second retaining portion 104 and on the outer side in the width direction of the plate-like cable connector 101 with respect to the contact 105. The guide mark 126 is removed from the upper surface of the resin portion 102B by an upper mold (not shown) used to form the upper surface side of the resin portion of the housing 102 when the contact 105 and the hold-down portion 102A are integrally formed. It is dented downward and formed into a linear shape.

  FIG. 11 is a perspective view of the plate-like cable connector 101 showing a state in which the FPC cable 301 is passed through the upper surface opening 121. In FIG. 11, the FPC cable 301 is indicated by a one-dot chain line. When attaching the FPC cable 301 to the plate-like cable connector 101, the operator holds the reinforcing plate 304 of the FPC cable 301 and the cable body 303, and attaches this reinforcing plate 304 to the first side of the plate-like cable connector 101. Positioned on the part 112 side. Subsequently, the operator moves the FPC cable 301 in the direction from the first side portion 112 toward the second side portion 113, slides the cable body 303, and passes through the upper surface opening 121 of the plate-like cable connector 101. Then, the cable body 303 is moved along the bottom surface portion 114 of the plate-like cable connector 101 (see FIGS. 5 and 8). At this time, the cable body 303 passes from the inside of the housing 102 through the extension opening 123 and extends to the second side 113 side.

  Please refer to FIG. Subsequently, the operator pulls both the reinforcing plate 304 and the cable body 303 in the direction of the arrow K (the direction from the first side portion 112 toward the second side portion 113), and slides the reinforcing plate 304 to move the tip. The reinforcing plate 304 is slid under the second retaining portion 104 through the side opening 122. At this time, the lower surface of the reinforcing plate 304 comes into contact with the base side portion of the elastic deformation portion 105C of the contact 105, and is then pushed up by the elastic deformation portion 105C of the contact 105, so that the reinforcing plate 304 and the contact 105 It is sandwiched between the retaining portion 104.

  The operator moves the reinforcing plate 304 to the second side 113 side until the end surface 304B of the reinforcing plate 304 hits the first retaining portion 103. At this time, the operator can visually prevent the FPC cable 301 from being incompletely inserted by visually aligning the end surface 304D on the first side portion 112 side of the reinforcing plate 304 with the guide mark 126. it can. As a result, the elastically deforming portion 105C of the contact 105 comes into contact with the terminal portion 302A of the FPC cable 301, and the reinforcing plate 304 comes into contact with the first retaining portion 103, the second retaining portion 104, and the contact 105 and is stabilized. Here, since the reinforcing plate 304 is supported by the reinforcing body support portion 127 at this time, even if the operator pushes the reinforcing plate 304 downward, the reinforcing plate 304 is received by the reinforcing body support portion 127 and the contact 105 is deformed. As a result, it is possible to prevent the force from being applied to the contact 105 to such an extent.

  Thus, the FPC cable 301 can be easily and reliably attached to the plate-like cable connector 101 of the present embodiment. In addition, since the reinforcing plate 304 is sandwiched and stabilized between the second retaining portion 104 and the contact 105, the height can be reduced.

  In the plate-like cable connector 101 of the present embodiment, as shown in FIG. 3, the flexible wiring 302 in the FPC cable 301 and the printed wiring 202 on the substrate 201 do not face each other. For this reason, when an electric signal flows through the flexible wiring 302 and the printed wiring 202, the magnetic field generated on the outer periphery thereof does not affect the electric signal, and an error occurs particularly in the case of an electric signal having a high frequency. Hateful.

  FIG. 12 is a perspective view of the plate-like cable connector 101 showing how the FPC cable 351 having a shape different from that in FIG. 2 is attached. The plate-like cable connector 101 according to the present embodiment does not have the wide portion 303A (see FIG. 2) formed at the end, and the two corners at the end are cut out in a rectangular shape in plan view. An FPC cable 351 having an end portion that looks like a convex shape and a reinforcing plate 352 attached to such an end portion can also be attached. In this case, the width dimension of the cable main body 353 of the FPC cable 351 substantially matches the width of the front end side opening 122 provided on the first side portion 112 side of the housing 102. Further, the width dimension of the distal end portion of the reinforcing plate 352 substantially matches the width of the extension side opening 123 provided on the second side 113 side of the housing 102. When the reinforcing plate 352 of the FPC cable 351 is slid and inserted from the front end side opening 122, the reinforcing plate 352 enters below the second retaining portion 104, and the end surface 352A of the notched region of the reinforcing plate 352 is the first retaining portion. The reinforcing plate 352 comes into contact with the first retaining portion 103, the second retaining portion 104, and the contact 105 and stabilizes by striking against the portion 103.

  Another embodiment will be described with reference to FIG. For convenience of explanation, this embodiment is referred to as a second embodiment. In this case, the same parts as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  FIG. 13 is a plan view of the plate-like cable connector 101. In the present embodiment, the contact 105 is attached in the opposite direction to that of the first embodiment. That is, in each case, a part of the middle of the contact 105 is embedded in a region on the second side 113 side of the resin portion 102B, and the substrate connecting portion 105B is on the second side from the bottom surface portion 114 formed by the resin portion 102B. The elastic deformation portion 105C protrudes above the bottom surface portion 114 and protrudes toward the first side portion 112 and is located above the central opening 124. The protrusion 113 protrudes toward the portion 113 and is connected to the substrate 201.

  Also in the present embodiment, when the FPC cable 301 (see FIG. 2 or the like) is attached to the plate-like cable connector 101, the operator reinforces the reinforcing plate 304 of the FPC cable 301 in the same manner as described with reference to FIG. (Refer to FIG. 2 and the like) is positioned on the first side portion 112 side of the plate-like cable connector 101, and the cable body 303 (see FIG. 2 and the like) is passed through the upper surface opening 121 of the plate-like cable connector 101. 303 is moved along the bottom surface portion 114 of the plate-like cable connector 101. At this time, the cable body 303 passes from the inside of the housing 102 through the extension opening 123 and extends to the second side 113 side. Subsequently, the operator pulls both the reinforcing plate 304 and the cable body 303 in the direction from the first side portion 112 toward the second side portion 113, and slides the reinforcing plate 304 to pass through the distal end side opening portion 122. Then, the reinforcing plate 304 is slid down below the second retaining portion 104. At this time, the lower surface of the reinforcing plate 304 pushes down the contact 105 after contacting the tip of the elastically deforming portion 105 </ b> C of the contact 105. The operator moves the end surface 304B of the reinforcing plate 304 (see FIG. 2 and the like) to the second side portion 113 side until it abuts against the first retaining portion 103, and the elastic deformation portion 105C of the contact 105 is moved to the terminal portion 302A of the FPC cable 301. The reinforcing plate 304 is brought into contact with the first retaining portion 103, the second retaining portion 104, and the contact 105 to be stabilized.

  As described above, the FPC cable 301 can be easily attached also to the plate-like cable connector 101 of the present embodiment. Further, the reinforcing plate 304 is stabilized by being sandwiched between the second retaining portion 104 and the contact 105, and the height can be reduced.

  It goes without saying that the FPC cable 351 shown in FIG. 12 can also be attached to the plate-like cable connector 101 of the present embodiment.
