  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. 4), and the hold-down portion 102A is fixed by reflow soldering or the like. The plate-like cable connector 101 can be attached with an FPC cable 301 (see FIGS. 2 and 3) as a plate-like cable, and a flexible wiring 302 (see FIG. 3) in the FPC cable 301 and a printed wiring 202 (see FIG. 3). (See FIG. 4).

  FIG. 2 is a perspective view of the FPC cable 301 viewed from the plane side. FIG. 3 is a perspective view of the FPC cable 301 viewed from the back side. Please refer to FIG. 2 and FIG. 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 refers to one surface of the cable body 303 that can be visually recognized in FIG. The first surface 303B and a second surface 303C, which will be described later, correspond to the “surface area of the cable body” in the claims.

  The other surface of the cable body 303 visible in FIG. 2 is referred to as a second surface 303C. A reinforcing plate 304 is attached to the end region of the second surface 303C. 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 rectangular shape that is long in the width direction of the cable body 303 in plan view. Both ends in the longitudinal direction of the reinforcing plate 304 are located on the wide portion 303A.

  An engagement protrusion 304E is provided in a region of the reinforcing plate 304 on the end 303D side of the cable body 303. The engagement protrusion 304E protrudes in a direction away from the surface area of the cable body 303. As an example, the engagement protrusion 304E is formed by bending the region of the reinforcing plate 304 on the side of the end 303D of the cable body 303 over the entire width of the reinforcing plate 304 along a fold line extending in the width direction of the cable body 303. The Thus, by providing the engagement protrusion 304E over the entire width of the reinforcing plate 304, warpage of the reinforcing plate 304 in the width direction of the FPC cable 301 is suppressed, and the contact state of the terminal portion 302A located at the center portion of the cable body 303 is good. Can be. The engaging plate 304E may be formed by bending the reinforcing plate 304 into a round shape without forming a crease. As another example, the engaging protrusion 304E and the reinforcing plate 304 may be molded of resin so that the engaging protrusion 304E and the reinforcing plate 304 are orthogonal to each other.

  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. 4 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 continues from the upper surface to an end surface that can be seen on the lower left side of FIG. 4 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 left side of FIG. 4 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. 4). As a result, the reinforcing plate 304 slides and enters the housing 102. Then, the engaging protrusion 304E is caught by the retaining portion 103 provided in the housing 102, and the retaining portion 103 and the contact 105 sandwich the reinforcing plate 304, whereby the FPC cable 301 is fixed to the plate-like cable connector 101. At this time, the contact 105 contacts the terminal portion 302A (see also FIG. 3) of the FPC cable 301, and the flexible wiring 302 (see also FIG. 3) in the FPC cable 301 and the printed wiring 202 on the substrate 201 are electrically connected. It is possible to transmit electrical signals. 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 left side of the drawing 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-like cable connector 101 will be described with reference to FIGS. 1, 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 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. 4) 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. 4 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 positions of the terminal portions 302A provided on the FPC cable 301 (see FIG. 3). 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 a terminal portion 302A (see FIG. 3) 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 retaining portion 103 provided in the housing 102 extends in the width direction of the plate-like cable connector 101 in parallel with the upper surface portion 111 and protrudes toward the inner side of the plate-like cable connector 101, and is flush with the upper surface of the upper surface portion 111. There is no. The retaining portion 103 interferes with the upper surface of the reinforcing plate 304 located in the housing 102 and prevents the reinforcing plate 304 from moving toward the upper surface portion 111.

  An end face on the first side portion 112 side in the retaining portion 103 is an engagement receiving portion 104. The engagement receiving portion 104 interferes with the engagement protrusion 304E of the reinforcing plate 304 that is about to move toward the second side portion 113, and is positioned within the housing 102 and further moves toward the second side portion 113 from there. The reinforcing plate 304 is prevented from falling off from the extension side opening 123.

  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 retaining portion 103 through the side opening 122. At this time, the lower surface of the reinforcing plate 304 is in contact with the base 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. 103.

  The operator moves the reinforcing plate 304 toward the second side portion 113 until the engagement protrusion 304E hits the engagement receiving portion 104 (see FIG. 1 and the like). 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 retaining portion 103 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 between the retaining portion 103 and the contact 105 and is stabilized, the height can be reduced.

  Further, in the plate-like cable connector 101 of this embodiment, as shown in FIG. 4, 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.

  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. 12 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 this embodiment, when the FPC cable 301 (see FIG. 2, FIG. 3 and the like) is attached to the plate-like cable connector 101, the operator uses the FPC cable 301 in the same manner as described based on FIG. The reinforcing plate 304 (see FIG. 2, FIG. 3, etc.) is positioned on the first side portion 112 side of the plate cable connector 101, and the cable body 303 (see FIG. 2, FIG. 3, etc.) is placed on the upper surface of the plate cable connector 101. The cable body 303 is moved along the bottom surface portion 114 of the plate-like cable connector 101 through the opening 121. 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 below the retaining portion 103. 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 reinforcing plate 304 toward the second side 113 until the engagement protrusion 304E (see FIGS. 2, 3 and the like) abuts against the engagement receiving portion 104, and moves the elastic deformation portion 105C of the contact 105 to the FPC cable 301. Then, the reinforcing plate 304 is brought into contact with the retaining portion 103 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 sandwiched between the retaining portion 103 and the contact 105 and is stable, and the height can be reduced.
