  In the figure, reference numeral 1 denotes a male connector as a first connector which is one of the sheet connectors in the present embodiment, and is electrically connected to a female connector 101 as a second connector which is a mating connector described later. The male connector 1 has a flat cable portion 12 and a flat connection portion 11 integrally formed at the tip of the cable portion 12. Note that intermediate recesses 13 as recesses for engaging with the female connector 101 are formed on the left and right sides of the boundary portion between the cable portion 12 and the connection portion 11.

  In the present embodiment, expressions showing directions such as upper, lower, left, right, front, rear, etc., used to explain the configuration and operation of each part included in the male connector 1, the female connector 101, and other members. Is not absolute but relative, and is appropriate when the male connector 1, female connector 101 and other parts included in the other members are in the posture shown in the figure. When the posture of each part included in the connector 101 and other members is changed, it should be interpreted according to the change in the posture.

  The male connector 1 has, for example, a dimension in the width direction of the connection portion 11 (direction connecting the upper left and lower right in FIG. 1) of about 10 to 15 mm, and the front-rear direction of the connection portion 11 (lower left in FIG. 1). The dimension of the connecting portion 11 in the thickness direction is approximately 0.3 to 0.5 mm, and the intermediate recess 13 is approximately 2 in the longitudinal direction. Although the member has a dimension of about 4 mm, the dimension can be changed as appropriate.

  The cable portion 12 is a flat flexible cable called a flexible circuit board (FPC: Flexible Printed Circuit), a flexible flat cable (FFC: Flexible Flat Cable), or the like. As long as it is a cable or a substrate, it may be of any kind. The cable portion 12 includes a base film 15 as a male substrate portion that is a plate-like first substrate portion that is an insulating thin plate member having an elongated strip shape, and one surface of the base film 15 (FIG. 7). A conductor pattern 51 as a male conductor, which is a first conductor functioning as a plurality of conductive wires arranged in parallel on the upper surface of FIG. Further, on the other surface of the conductor pattern 51 (upper surface in FIG. 7), a cover film 17 as a male covering portion which is a plate-like first covering plate portion which is an insulating thin plate member having an elongated strip shape is formed. It is arranged. That is, the cable portion 12 is a flat member having a layer structure in which the base film 15, the conductor pattern 51, and the cover film 17 are laminated in this order from the bottom.

  The base film 15 and the cover film 17 are made of, for example, a resin such as polyimide, but may be made of any kind of material as long as it has insulating properties. The conductor pattern 51 is formed by, for example, etching a copper foil (foil) having a thickness of several [μm] to several tens [μm], which is pasted on one surface of the base film 15 in advance. And formed by patterning.

  The example shown in the figure shows a case where the male connector 1 is used for connection to a power supply, and the conductor pattern 51 includes a pair of wide patterns 51a and a pair of narrow patterns arranged in parallel to each other. The adjacent conductor patterns 51 are separated from each other by a pattern separation space 52. For example, the wide pattern 51a is used as a ground line, and the narrow pattern 51b is used as a power line. In addition, the number of the said conductor patterns 51, a pitch, and the aspect of arrangement | sequence can be changed suitably as needed. For example, when the male connector 1 is used for signal line connection, each conductor pattern 51 is formed like a narrower linear body and has a predetermined pitch, for example, 0.1 [ mm], and a large number of them are arranged in parallel with each other.

  The cable portion 12 is usually a long belt-like member, but in the drawing, for the sake of illustration, the rear portion (upper right in FIG. 1) is cut away. Note that another flat cable can be connected behind the cable portion 12.

  The connecting portion 11 also has a base film 15 and a conductor pattern 51 disposed on one surface of the base film 15. The conductor pattern 51 is formed continuously from the cable portion 12 and terminates in the connection portion 11. In the example shown in the figure, the conductor pattern 51 extends to the distal end portion 11a of the connection portion 11 and terminates at the distal end portion 11a. However, the conductor pattern 51 may terminate in the middle of the connection portion 11. A reinforcing layer 16 as a plate-shaped reinforcing plate portion, which is a flat thin plate member, is disposed on the other surface of the base film 15 (the lower surface in FIG. 7). The reinforcing layer 16 is made of, for example, a metal such as stainless steel. The material thereof may be a resin, a composite material including glass fiber, carbon fiber, or the like, or any kind of material. It may be. That is, the connection part 11 is a flat plate-like member having a layer structure in which the reinforcing layer 16, the base film 15, and the conductor pattern 51 are laminated in this order from the bottom.

  And the ear | edge part 21 extended in the width direction outer side rather than the intermediate | middle recessed part 13 is respectively provided in the right-and-left both sides of the said connection part 11. As shown in FIG. The ear portion 21 is a portion that functions as a convex portion for engaging with the female connector 101, and a rear end portion thereof is a male fitting lock portion 22 as a fitting lock portion. Then, the male fitting lock portion 22 engages with a female fitting lock portion 122 of the female connector 101 described later, and locks so that the fitting state between the male connector 1 and the female connector 101 is maintained.

  In the example shown in the figure, the width dimension of the connection part 11 is equal to the width dimension of the cable part 12, but it is not necessarily equal to the width dimension of the cable part 12. It may be larger or smaller.

  The ear portion 21 is a strip-like thick portion extending in the front-rear direction of the male connector 1 and includes an insertion convex portion 56 protruding upward from the surface of the connection portion 11. The side edge of the insertion convex portion 56 is formed so as to coincide with the side edge 21 a of the ear portion 21, and is recessed inward in the width direction at a portion near the rear end thereof, that is, a portion near the male fitting lock portion 22. A locking recess 56a formed to enter is provided. The locking recess 56a is locked to a locking projection 156a of the female connector 101 described later, and prevents the engagement between the male fitting lock portion 22 and the female fitting lock portion 122 from being released.

  In the example shown in the figure, the insertion convex portion 56 is formed integrally with the conductor pattern 51 on the surface of the conductor pattern 51, but is not necessarily a member integral with the conductor pattern 51. A member separate from the conductor pattern 51 may be used.

  As shown in FIGS. 2 to 4, the male fitting lock portion 22 includes a male side step portion 23 as a first fitting step portion formed on the back surface. The male side step portion 23 is a step portion formed so as to be recessed from the back surface of the connection portion 11, more specifically, from the back surface of the reinforcing layer 16, and is substantially orthogonal to the back surface of the connection portion 11, The step part end surface 23a extended in the direction parallel to the width direction of the connection part 11 and the level | step difference surface 23b extended in parallel with the back surface of the connection part 11 are included. The boundary on the inner side in the width direction of the connection portion 11 in the male side step portion 23 is defined by the side edge 13 a of the intermediate recess 13.

  In the connection portion 11, the surface of the conductor pattern 51 is exposed, and a plurality of protruding terminals 53 as male terminals which are first terminals are disposed on the surface of the conductor pattern 51. In the example shown in the figure, the projecting terminals 53 are arranged in a lattice shape and are arranged so as to form a pair of rows extending in the width direction. Specifically, in the wide pattern 51a, three protruding terminals 53 are included in each row, and in the narrow pattern 51b, one protruding terminal 53 is included in each row, and protruding terminals in the front row and the rear row are included. 53 is located on a straight line extending in the front-rear direction of the male connector 1. That is, the male connector 1 is arranged so as to form a rectangular (2) planar lattice having lattice lines as axes extending in the front-rear direction and the left-right direction. In addition, the arrangement | sequence aspect of the protrusion terminal 53 is not limited to the example shown by a figure, It can change arbitrarily.

  Each of the protruding terminals 53 is a member protruding upward from the surface of the conductor pattern 51, and is formed integrally with the conductor pattern 51 by, for example, a method such as etching using a photolithography technique. The height of the protruding terminal 53, that is, the position of the upper surface is the same as the position of the upper surface of the insertion convex portion 56 in the example shown in FIG. It is not necessary to be the same as the position of the upper surface, and may be higher or lower than the position of the upper surface of the insertion convex portion 56.

  Further, the shape of the upper surface and the transverse section of the protruding terminal 53 is larger in the front-rear direction than in the width direction, as clearly shown in FIG. The upper part in a) is preferably a pentagon or hexagon like a baseball base with a pointed base, but it is not necessarily limited to the example shown in the figure. ) It may be circular and can be changed arbitrarily.

  In the present embodiment, the side shape of the protruding terminal 53 is concave as shown in FIG. Specifically, in the protruding terminal 53, the width dimension of the base end portion 53a that is a portion connected to the surface of the conductor pattern 51 is equal to or larger than the width size of the tip end portion 53b that is the upper end portion, and the base end portion 53a and The side surface portion 53c between the distal end portion 53b is a smooth and smooth surface that is recessed toward the inner side in the width direction from the proximal end portion 53a and the distal end portion 53b, and in the middle thereof, The minimum point 53d where the width dimension is minimum is included. In other words, the width dimension of the protruding terminal 53 is the maximum at the base end portion 53a, gradually decreases as it goes upward, becomes minimum at the minimum point 53d, increases gradually as it goes further upward, and increases at the tip end portion 53b. The size is the same as or smaller than that of the base end portion 53a. The shape of the side surface portion 53c is desirably a gently continuous curved surface, but may be a curved surface in which a plurality of slopes are continuous.

  Moreover, the side shape of the protruding terminal 53 when viewed from the side of the male connector 1 is also a concave surface as shown in FIG. That is, the width dimension of the base end part 53a is equal to or larger than the width dimension of the tip end part 53b, and the side surface part 53c is a surface that is recessed toward the inside in the width direction from the base end part 53a and the tip end part 53b. In the middle, a minimum point 53d having a minimum width dimension is included. In other words, the width dimension of the protruding terminal 53 is the maximum at the base end portion 53a, gradually decreases as it goes upward, becomes minimum at the minimum point 53d, increases gradually as it goes further upward, and increases at the tip end portion 53b. The size is the same as or smaller than that of the base end portion 53a.

  When the protruding terminal 53 is engaged with a receiving terminal 153 as a mating terminal which is a second terminal described later of the female connector 101, the side surface portion 53c is viewed from both sides by a pair of contact portions 153c described later of the receiving terminal 153. It will be in the state clamped elastically. As will be described later, the receiving terminal 153 is a thin member, and the thickness dimension (vertical dimension) of the contact portion 153c is smaller than the height dimension (vertical dimension) of the protruding terminal 53. When receiving an external force or receiving a vibration, the contact portion 153c may move in the vertical direction of the protruding terminal 53 along the side surface portion 53c. However, since the side surface portion 53c is a smooth concave surface and includes the minimum point 53d, the position of the contact portion 153c elastically pressed by the side surface portion 53c always converges to the minimum point 53d, and the Since the elastic pressing force increases as the distance from the minimum point 53d increases, the contact portion 153c does not separate from the side surface portion 53c. That is, since the side surface portion 53c is concave, contact between the side surface portion 53c and the contact portion 153c is reliably maintained even when subjected to external force or vibration. No interruption occurs.

  Next, the configuration of the female connector 101 will be described.

  8 is a perspective view of the female connector according to the embodiment of the present invention as viewed from the front side, FIG. 9 is a three-view diagram of the female connector according to the embodiment of the present invention, and FIG. 10 is a diagram of the female connector according to the embodiment of the present invention. FIG. 11 is a perspective view of the reinforcing layer of the female connector in the embodiment of the present invention, and FIG. 12 is a top view showing a modification of the female terminal of the female connector in the embodiment of the present invention. . 9A is a top view, FIG. 9B is a front view, FIG. 9C is a bottom view, and FIGS. 12A to 12D are first to fourth modified examples. is there.

  In the present embodiment, the female connector 101 is a second connector as the other of the seat connector, has a rectangular planar shape, and is electrically connected to the male connector 1 as the first connector. It is mounted on the surface of a substrate such as a printed circuit board or a flexible circuit board (not shown). In this case, the female connector 101 has a flat plate shape, is mounted so that the back surface thereof faces the front surface of the substrate, and is electrically connected to the conductive traces of the substrate.

  The female connector 101 has a flat frame body 111 having a substantially U-shaped surface. The frame 111 extends in the width direction of the female connector 101 (the direction connecting the lower left and the upper right in FIG. 8), and forward from both ends of the horizontal frame 111a (lower left in FIG. 8). A vertical frame portion 111b extending toward the front is provided. A wide portion 113 that engages with the intermediate recess 13 of the male connector 1 is formed at the front end of the vertical frame portion 111b.

  And the flat flat recessed part provided with the rectangular planar shape demarcated by the said frame 111 is the connection recessed part 114 which accommodates the connection part 11 of the male connector 1. FIG. The bottom 114a of the connection recess 114 is a flat member having a layer structure in which a base film 115, a conductor pattern 151, and a cover film 117 are laminated in this order from the bottom. The frame body 111 is a thick plate-like member as compared with the connection recess 114.

  The female connector 101 has, for example, a width of the frame body 111 of about 11 to 16 [mm], and a front and rear direction of the frame body 111 (a direction connecting the lower left and the upper right in FIG. 8) of about 5 to 5. Although it is a plate-shaped member having a dimension of 7 [mm] and a thickness of the frame body 111 of about 0.3 to 0.5 [mm], the dimension can be changed as appropriate.

  The conductor pattern 151 is a female conductor as a second conductor that functions as a plurality of conductive wires, and is etched into a copper foil having a spring property with a thickness of several [μm] to several tens [μm], for example. It is formed by applying patterning and the like.

  The example shown in the figure shows a case where the female connector 101 is used for connection to a power source, and the conductor pattern 151 includes a pair of wide patterns 151a and a pair of narrow patterns arranged in parallel to each other. The adjacent conductor patterns 151 are separated from each other by a pattern separation space 152. For example, the wide pattern 151a is used as a ground line, and the narrow pattern 151b is used as a power line. Note that the number, pitch, and arrangement of the conductor patterns 151 can be changed as appropriate. For example, when the female connector 101 is used for signal line connection, each conductor pattern 151 is formed like a narrower linear body and has a predetermined pitch, for example, 0.1 [ mm], and a large number of them are arranged in parallel with each other.

  In the figure, 158a and 158b are a wide rear tail portion and a narrow rear tail portion formed integrally with the wide pattern 151a and the narrow pattern 151b so as to protrude rearward from the horizontal frame portion 111a of the frame body 111. And connected to a connection pad formed on the surface of the substrate (not shown) by soldering or the like. Reference numeral 158c denotes a front tail portion formed integrally with the wide pattern 151a so as to protrude forward from the wide portion 113 of the frame body 111, and is soldered to a connection pad formed on the surface of the substrate (not shown). Connected by appending etc. When the wide rear tail portion 158a, the narrow rear tail portion 158b and the front tail portion 158c are described in an integrated manner, the tail portion 158 will be described. By connecting the tail portion 158 to the connection pad, the female connector 101 is fixed to the substrate, and the conductor pattern 151 is electrically connected to the corresponding conductive trace of the substrate.

  A plurality of receiving terminals 153 as female terminals, which are second terminals, are disposed in a portion of the conductor pattern 151 corresponding to the bottom 114a of the connection recess 114. Since the receiving terminal 153 is a member that fits and conducts with the protruding terminal 53 of the male connector 1, the arrangement thereof is the same as the arrangement of the protruding terminal 53. And when the arrangement | sequence aspect of the protrusion terminal 53 is changed, the arrangement | sequence aspect of the receiving terminal 153 is also changed so that it may adapt. Furthermore, since the conductor pattern 151 is also a member that conducts with the conductor pattern 51 of the male connector 1, the arrangement thereof is the same as the arrangement of the conductor pattern 51 of the male connector 1. When is changed, the arrangement pattern of the conductor pattern 151 is also changed so as to be adapted thereto.

  Each of the receiving terminals 153 is a member accommodated in a substantially rectangular terminal accommodating opening 154 that penetrates the conductor pattern 151 in the thickness direction. For example, the conductor pattern 153 is formed by a method such as etching using a photolithography technique. It is formed by patterning 151. Typically, the remaining pattern formed by patterning the conductor pattern 151 is the receiving terminal 153, and the portion where the material around the receiving terminal 153 is removed is the terminal receiving opening 154. Therefore, the thickness dimension of the receiving terminal 153 is equivalent to the thickness dimension of the conductor pattern 151.

  The planar shape of each receiving terminal 153 is bilaterally symmetric. Each receiving terminal 153 includes a base portion 153a connected to the periphery of the terminal receiving opening 154, a pair of arm portions 153d connected to the base portion 153a, a pair of contact portions 153c connected to the tips of the arm portions 153d, A pair of free ends 153b connected to the tips of the contact portions 153c is provided. The left and right arm portions 153d, the contact portion 153c, and the free end portion 153b are symmetrical members that face each other. The arm portion 153d is a cantilever-like member that functions as a spring, and the free end portion 153b and the contact portion 153c are elastically displaced in the width direction of the female connector 101 due to the spring property of the arm portion 153d.

  The terminal receiving opening 154 includes an inner opening 154 a inside the receiving terminal 153 and an outer opening 154 b outside the receiving terminal 153. The inner opening 154a is a portion into which the protruding terminal 53 enters and is accommodated when the receiving terminal 153 is engaged with the protruding terminal 53 of the male connector 1, and the outer opening 154b is the arm portion 153d, This is a portion that allows displacement of the free end portion 153b and the contact portion 153c.

  In the inner opening 154a, the portion between the opposing arm portions 153d has a large area, and typically the width dimension is larger than the width dimension of the distal end portion 53b of the protruding terminal 53, and The vertical dimension is also larger than the vertical dimension of the tip 53 b of the protruding terminal 53. Therefore, the protruding terminal 53 can smoothly enter the inner opening 154a. On the other hand, the portion between the contact portions 153 c facing each other is a narrow space, and typically the width dimension is smaller than the width dimension at the minimum point 53 d of the protruding terminal 53. Therefore, when the projecting terminal 53 accommodated in the inner opening 154a moves relatively between the contact portions 153c, the interval between the contact portions 153c abuts on the side surface portion 53c of the projecting terminal 53 and is expanded. The contact portion 153c is pressed against the side surface portion 53c of the protruding terminal 53 by the spring property of the arm portion 153d. That is, the pair of contact portions 153c elastically sandwich the side surface portion 53c of the protruding terminal 53 from both sides.

  The shape of the inner opening 154a is such that the width dimension gradually decreases when approaching the portion between the contact portions 153c. That is, the vicinity of the contact portion 153c at the side edge of the opposing arm portion 153d has an inclined tapered shape. Therefore, the protruding terminal 53 can smoothly enter the portion between the contact portions 153c facing each other.

  In the vicinity of both ends of the conductor pattern 151 in the width direction, insertion concave portions 156 that are substantially rectangular openings for accommodating the insertion convex portions 56 of the male connector 1 are formed. Each of the insertion recesses 156 is an opening that penetrates the conductor pattern 151 in the thickness direction, similarly to the terminal receiving opening 154. For example, the conductor pattern 151 is patterned by a method such as etching using a photolithography technique. It is formed by doing. A locking projection 156a is formed on the outer edge of the insertion recess 156 near the front end. The locking projection 156a is a projection formed at the tip of a cantilever member that functions as a spring, and is elastically displaced in the width direction of the female connector 101 by the spring property of the cantilever member. The locking projection 156 a locks a locking recess 56 a formed on the side edge of the insertion projection 56 of the male connector 1, and the engagement between the male fitting lock portion 22 and the female fitting lock portion 122. Prevents the combination from being released.

  The base film 115 is a female substrate portion as a second substrate portion that is an insulating thin plate member, and is made of, for example, a resin such as polyimide, but may be any kind of material as long as it has an insulating property. May be. The base film 115 has a terminal-corresponding opening 115a and a recess-corresponding opening 115b penetrating the base film 115 in the thickness direction at portions corresponding to the receiving terminals 153 and the insertion recesses 156 formed in the conductor pattern 151. Each is formed. The receiving terminals 153 form a pair of rows extending in the width direction, and are arranged so that the receiving terminals 153 in the front row and the rear row are positioned on a straight line extending in the front-rear direction of the female connector 101. Whereas, each of the terminal corresponding openings 115a has a rectangular shape that is long in the front-rear direction so as to correspond to the pair of receiving terminals 153 in the front row and the rear row.

  The cover film 117 is a female covering portion as a second covering plate portion that is an insulating thin plate member, and is made of, for example, a resin such as polyimide. It may be a material. The cover film 117 has a terminal-corresponding opening 117a and a recess-corresponding opening 117b penetrating the cover film 117 in the thickness direction at portions corresponding to the receiving terminals 153 and the insertion recesses 156 formed in the conductor pattern 151. Each is formed. Each of the terminal corresponding openings 117a has a rectangular shape elongated in the front-rear direction so as to correspond to the pair of receiving terminals 153 in the front row and the rear row.

  And the bottom part 114a of the connection recessed part 114 formed by laminating | stacking the said base film 115, the conductor pattern 151, and the cover film 117 is equipped with the ear | edge accommodation recessed part 121 arrange | positioned at the width direction both ends. The ear receiving recess 121 corresponds to the recess-corresponding opening 115b of the base film 115, the insertion recess 156 of the conductor pattern 151, and the recess-corresponding opening 117b of the cover film 117, and is an opening that penetrates the bottom 114a in the thickness direction. ing. The terminal accommodating opening 154 corresponds to the terminal corresponding opening 115a of the base film 115 and the terminal corresponding opening 117a of the cover film 117, and is an opening that penetrates the bottom 114a in the thickness direction. In the example shown in the figure, the conductor pattern 151 and the cover film 117 do not exist in the corresponding part between the left and right wide portions 113, and only the base film 115 exists.

  Further, a frame reinforcing layer 116 is laminated on the cover film 117. The frame reinforcing layer 116 is a thin plate member having a substantially U-shaped surface shape, and is made of, for example, a metal such as stainless steel or a resin such as polyimide. It may be a material or an insulating material. Further, as shown in FIG. 10, the frame reinforcing layer 116 may be a member formed by laminating a first frame reinforcing layer 116a and a second frame reinforcing layer 116b, as shown in FIG. As a result, a single member configured integrally may be used. As shown in FIG. 10, when the first frame reinforcing layer 116a and the second frame reinforcing layer 116b are laminated, for example, the material of the first frame reinforcing layer 116a is a metal such as stainless steel. In addition, different materials can be used in combination such that the second frame reinforcing layer 116b is made of resin such as polyimide.

  The frame reinforcing layer 116 is a member constituting the uppermost layer of the frame body 111, and the surface shape thereof matches the surface shape of the frame body 111. As shown in FIG. 11, the frame reinforcing layer 116 has a wide portion 116c corresponding to the wide portion 113 of the frame 111, and the rear end portion of the wide portion 116c is a female as a fitting lock portion. It functions as the fitting lock part 122. Since the wide portion 113 is located at the rear end of the ear receiving recess 121, the female fitting lock portion 122 becomes the rear end portion of the ear receiving recess 121 and engages with the male fitting lock portion 22 of the male connector 1. Then, the male connector 1 and the female connector 101 are locked so that the fitted state is maintained.

  The female fitting lock portion 122 includes a female side step portion 123 as a second fitting step portion formed on the back surface. The female-side step portion 123 is a step portion that is formed so as to be recessed from the back surface of the frame reinforcing layer 116, and is substantially orthogonal to the back surface of the frame reinforcing layer 116 and the surface of the female connector 101. It includes a stepped end surface 123a extending in a direction parallel to the width direction, and a stepped surface 123b extending in parallel to the back surface of the frame reinforcing layer 116 and the surface of the female connector 101. The step end surface 123a corresponds to the front edge of the recess-corresponding opening 115b of the base film 115, the insertion recess 156 of the conductor pattern 151, and the recess-corresponding opening 117b of the cover film 117.

  In the present embodiment, the planar shape of the receiving terminal 153 is not necessarily limited to the example shown in FIGS. 8 to 10, and is the shape shown in FIGS. 12 (a) to 12 (d). May be. In addition, the upper side and the lower side in FIGS. 12A to 12D correspond to the front side and the rear side of the female connector 101.

  In the example shown in FIG. 12A, the planar shape of the receiving terminal 153 is left-right symmetric and vertically symmetric. The receiving terminal 153 includes a base portion 153a connected to each of the left and right side edges of the terminal receiving opening 154, and is separated into a left side portion and a right side portion having a symmetric plane shape. Each of the left side portion and the right side portion includes an arm portion 153d connected to each of the upper and lower base portions 153a and a contact portion 153c connecting the tips of the upper and lower arm portions 153d, and has a vertically symmetrical plane shape.

  The terminal accommodating opening 154 includes a pair of upper and lower inner openings 154a located between the left and right arm parts 153d and a pair of left and right outer openings 154b located outside the contact part 153c. And the space | interval of the contact parts 153c which right and left oppose is narrower than the space | interval of arm parts 153d.

  The shape of the inner opening 154a is such that the width dimension gradually decreases when approaching the portion between the contact portions 153c. That is, the vicinity of the contact portion 153c at the side edge of the opposing arm portion 153d has an inclined tapered shape. Therefore, the protruding terminal 53 can smoothly enter the portion between the contact portions 153c facing each other.

  In the example shown in FIG. 12A, the protruding terminal 53 can be inserted into any of the upper and lower inner openings 154a. Therefore, when the male connector 1 and the female connector 101 are fitted, the male connector 1 and the female connector The degree of freedom of the relative position with the connector 101 is large, and the fitting operation can be easily performed. Further, since both the upper and lower sides of the contact portion 153 c are so-called doubly supported beams (flashes) supported by the arm portion 153 d, the spring force for supporting the contact portion 153 c is large, and the pair of contact portions 153 c has the protruding terminals 53. The force which elastically clamps the side surface portion 53c from both sides is large, and the contact between the side surface portion 53c and the contact portion 153c can be more reliably maintained.

  In the example shown in FIG. 12 (b), the receiving terminal 153 includes a base portion 153a connected to each of the left and right side edges of the terminal receiving opening 154, and a left side portion and a right side portion having a bilaterally symmetric planar shape. Have been separated. Each of the left part and the right part includes an arm part 153d connected to each of the upper and lower base parts 153a and a contact part 153c that connects the tips of the upper and lower arm parts 153d, but the planar shape is not vertically symmetrical. .

  The upper base portion 153a1 is located near the upper edge of the terminal accommodating opening 154, while the lower base portion 153a2 is located substantially in the middle of the upper and lower sides of the terminal accommodating opening 154. The contact portion 153c exists at a position closer to the lower side than the upper and lower middles of the terminal accommodating opening 154. In addition, the planar shape of the upper arm portion 153d1 is a substantially straight or a large bent shape, but the planar shape of the lower arm portion 153d2 is a slightly curved J shape or U shape. The inner opening 154a is positioned between the left and right upper arm portions 153d1.

  The shape of the inner opening 154a is such that the width dimension gradually decreases when approaching the portion between the contact portions 153c. That is, the vicinity of the contact portion 153c at the side edge of the opposing arm portion 153d has an inclined tapered shape. Therefore, the protruding terminal 53 can smoothly enter the portion between the contact portions 153c facing each other.

  In the example shown in FIG. 12B, the upper side of the inner opening 154a is larger than the lower side. Therefore, the inner opening 154a can be made larger compared to the example shown in FIG. When the female connector 101 and the female connector 101 are fitted, the relative position between the male connector 1 and the female connector 101 is large, and the fitting operation can be easily performed. Further, if the size of the inner opening 154a is made equal to the example shown in FIG. 12A, the size of the terminal receiving opening 154 as a whole can be reduced, and the arrangement density of the terminal receiving openings 154 and the receiving terminals 153 is reduced. Can be high. Furthermore, since the upper and lower arm portions 153d are long, so-called spring lengths are long, the range in which the contact portion 153c can be elastically displaced is widened, and the width dimension of the side surface portion 53c of the protruding terminal 53 is changed over a wide range. Therefore, the contact between the side surface portion 53c and the contact portion 153c can be more reliably maintained.

  In the example shown in FIGS. 12C and 12D, the receiving terminal 153 includes a base portion 153a connected to each of the left and right side edges of the terminal receiving opening 154, and has a left and right symmetrical plane shape. And the right part. Each of the left part and the right part includes an arm part 153d connected to each of the upper and lower base parts 153a and a contact part 153c that connects the tips of the upper and lower arm parts 153d, but the planar shape is not vertically symmetrical. .

  The upper base portion 153a1 is located near the upper edge of the terminal accommodating opening 154, and the lower base portion 153a2 is located near the lower edge of the terminal accommodating opening 154. The contact portion 153c exists at a position closer to the lower side than the upper and lower middles of the terminal accommodating opening 154. In addition, the planar shape of the upper arm portion 153d1 is a substantially straight or a large bent shape, but the planar shape of the lower arm portion 153d2 is a slightly curved S shape or N shape. The inner opening 154a is positioned between the left and right upper arm portions 153d1.

  In the example shown in FIGS. 12C and 12D, the length of the lower arm portion 153d2 is longer than that in the example shown in FIG. 12B, so that the spring length is longer and the side surface of the protruding terminal 53 is longer. A wider range of changes in the width dimension of the portion 53c can be accommodated. The other points are the same as in the example shown in FIG.

  Next, an operation of fitting the male connector 1 and the female connector 101 having the above-described configuration will be described.

  FIG. 13 is a diagram showing a mating process between the male connector and the female connector in the embodiment of the present invention, and FIG. 14 shows a state where the mating process between the male connector and the female connector in the embodiment of the present invention is completed. FIG. 15 is a three-sided view showing a state in which the mating process between the male connector and the female connector in the embodiment of the present invention is completed, and FIG. 16 is a diagram of the mating between the male connector and the female connector in the embodiment of the present invention. It is a principal part enlarged view which shows the state which the joint process was completed, and is the F section enlarged view in FIG.15 (c). In addition, in FIG. 13, (a)-(c) is a figure which shows each process, In FIG. 15, (a) is a top view, (b) is a front view, (c) is a sectional side view ( It is EE arrow sectional drawing in b).

  Here, it is assumed that the female connector 101 is surface-mounted on the substrate by connecting the tail portion 158 to a connection pad formed on the surface of the substrate (not shown) by soldering or the like. The female connector 101 is mounted in such a posture that the back surface thereof faces the front surface of the substrate. In addition, the substrate is used for, for example, a personal computer, a mobile phone, a PDA, a digital camera, a video camera, a music player, a game machine, an electronic device such as a vehicle navigation device, and an electric device such as a home appliance. Although it is a circuit board, a flat circuit cable such as a flexible circuit board, a flexible flat cable, or the like, any kind of board may be used.

  First, as shown in FIG. 13A, the operator determines the posture of the male connector 1 such that the surface on which the protruding terminals 53 are formed faces the surface of the female connector 101, that is, the surface of the male connector 1 is female. The male connector 1 is positioned above the female connector 101 so as to face the surface of the connector 101 and so that the distal end portion 11a of the connecting portion 11 coincides with the inner surface of the horizontal frame portion 111a of the frame 111.

  Subsequently, the operator lowers the male connector 1 relative to the female connector 101, that is, moves the male connector 1 in the fitting direction, so that the connection portion 11 is in the connection recess 114 as shown in FIG. The surface which is the fitting surface of the male connector 1 and the surface which is the fitting surface of the female connector 101 are brought into contact with or close to each other so that the wide portion 113 is located in the intermediate recess 13. In this case, the front end portion 11 a of the connection portion 11 is brought into contact with or close to the inner side surface of the horizontal frame portion 111 a of the frame body 111. Thereby, the connection part 11 and the connection recessed part 114 engage, and the intermediate | middle recessed part 13 and the wide part 113 engage. The left and right ear portions 21 of the connection portion 11 engage with the left and right ear accommodation recess portions 121 of the connection recess portion 114, and the insertion convex portion 56 positioned at the end of the ear portion 21 is an insertion part of the ear accommodation recess portion 121. Enter the recess 156. In addition, each of the protruding terminals 53 enters the inner opening 154 a inside the corresponding receiving terminal 153. Note that the distal end portion 11 a of the connection portion 11 is separated from the inner side surface of the horizontal frame portion 111 a of the frame body 111.

  Subsequently, the operator slides the male connector 1 in the locking direction relative to the female connector 101. That is, the male connector 1 is moved relative to the female connector 101 rearward (lower left in FIG. 13B) with the surface of the male connector 1 and the surface of the female connector 101 in contact with each other. In this case, each protruding terminal 53 enters the inner opening 154a inside the corresponding receiving terminal 153, and the insertion convex portions 56 of the left and right ear portions 21 are inserted into the insertion concave portions 156 of the left and right ear accommodating concave portions 121. Since it slides and guides in the approached state, the posture of the male connector 1 with respect to the female connector 101 is not disturbed.

  Then, as shown in FIGS. 13C and 14, when the fitting between the male connector 1 and the female connector 101 is completed, the male fitting lock portions 22 of the left and right ear portions 21 in the male connector 1 are connected to the female connector 101. The left and right wide portions 113 engage with the female fitting lock portions 122. Specifically, the male side step portion 23 of the male fitting lock portion 22 is engaged with the female side step portion 123 of the female fitting lock portion 122, and the step end face 23a and the step surface of the male side step portion 23 are engaged. 23b faces the stepped end surface 123a and the stepped surface 123b of the female side stepped portion 123 in contact with or close to each other. Thereby, the male connector 1 and the female connector 101 are locked, and a fitting state is maintained.

  Further, since the locking convex portion 156 a of the insertion concave portion 156 locks the locking concave portion 56 a of the insertion convex portion 56, the connection portion 11 cannot be slid, and the male connector 1 is relatively against the female connector 101. Slide in the locking direction is prevented. Therefore, even if external force or vibration is received, the male connector 1 does not slide relative to the female connector 101 in the anti-locking direction and the lock is not released. The fitting state with the female connector 101 is maintained. Note that the force of the operator's fingers is sufficiently larger than the spring force applied to the locking projection 156a, so that when the operator slides the male connector 1 relative to the female connector 101 in the anti-lock direction. Can release the locking by releasing the locking between the locking projection 156a and the locking recess 56a.

  Furthermore, when the male connector 1 is slid relative to the female connector 101 in the locking direction, that is, rearward, the protruding terminal 53 that has entered the inner opening 154a inside the receiving terminal 153 is moved into the inner opening 154a. Are moved relative to each other and enter between the contact portions 153c facing each other as shown in FIG. As a result, the distance between the contact portions 153c is abutted against the side surface portion 53c of the protruding terminal 53 and is expanded, so that the contact portion 153c is pressed against the side surface portion 53c of the protruding terminal 53 by the spring property of the arm portion 153d. become. That is, the pair of contact portions 153c elastically sandwich the side surface portion 53c of the protruding terminal 53 from both sides. As described above, the contact portion 153c holding the side surface portion 53c of the protruding terminal 53 also contributes to maintaining the fitted state.

  Further, since the receiving terminal 153 is a thin member, and the thickness dimension of the contact portion 153c is smaller than the height dimension of the protruding terminal 53 as shown in FIG. 16, the dimensional error (tolerance) and shape of each part Even if a misalignment in the fitting direction between the male connector 1 and the female connector 101 occurs between the projecting terminal 53 and the receiving terminal 153 due to distortion or the like, all the projecting terminals 53 can cope. It surely enters the inner opening 154a inside the receiving terminal 153, and the side surface portion 53c and the contact portion 153c come into contact with each other.

  The shape of the inner opening 154a is such that the width dimension gradually decreases when approaching the portion between the contact portions 153c. Further, in the example shown in the figure, the shape of the cross section of the protruding terminal 53 is a shape with a sharp back. Therefore, when it moves back and approaches between the contact parts 153c which oppose, it can approach smoothly and can expand the space | interval of contact parts 153c.

  Further, the receiving terminal 153 is a thin member, and as shown in FIG. 16, the thickness dimension of the contact portion 153c is smaller than the height dimension of the protruding terminal 53, so that the receiving terminal 153 is subjected to external force or vibration. In some cases, the contact portion 153c may move in the vertical direction of the protruding terminal 53 along the side surface portion 53c. However, since the side surface portion 53c is a concave surface and includes the minimum point 53d, the position of the contact portion 153c elastically pressed by the side surface portion 53c always converges to the minimum point 53d and is separated from the minimum point 53d. Since the elastic pressing force is increased, the contact portion 153c is not separated from the side surface portion 53c. That is, since the side surface portion 53c is concave, contact between the side surface portion 53c and the contact portion 153c is reliably maintained even when subjected to external force or vibration. No interruption occurs.

  Note that the operation for releasing the fitting between the male connector 1 and the female connector 101 is only the operation opposite to the operation for fitting the male connector 1 and the female connector 101, and thus the description thereof is omitted.

  As described above, in the present embodiment, the sheet connector includes the flat cable portion 12 and the flat connection portion 11 connected to the tip of the cable portion 12, and the protruding terminal 53 is disposed on one surface. The male connector 1 including the connected connection portion 11, the flat frame body 111, and the connection recess 114 defined by the frame body 111 and having a receiving terminal 153 disposed on the bottom 114a thereof. 114 and a female connector 101 that fits into the male connector 1. The male connector 1 includes intermediate recesses 13 formed on both sides in the width direction at the boundary portion between the cable portion 12 and the connection portion 11. The portion 11 includes ears 21 extending outward in the width direction from the intermediate recess 13 at both ends in the width direction, the connection recess 114 includes ear receiving recesses 121 disposed at both ends in the width direction, and the frame 111 , Each earpiece The connecting portion 11 is connected so as to include the wide portion 113 positioned at one end of the concave portion 121, the surface on which the protruding terminal 53 is disposed is opposed to the bottom portion 114 a, and the ear portion 21 is engaged with the ear accommodating concave portion 121. While being accommodated in the recess 114, the intermediate recess 13 and the wide portion 113 are engaged, and the connection portion 11 is slid to engage the end portion of the ear portion 21 and the end portion of the wide portion 113. The connector 1 and the female connector 101 are locked.

  As a result, the male connector 1 and the female are simply moved by sliding the connecting portion 11 so that the end portions of the ear portions 21 at both ends of the connecting portion 11 are engaged with the end portions of the wide portion 113 of the frame body 111. Since the connector 101 can be locked, the male connector 1 and the female connector 101 can be easily locked in a short time. Further, since the male connector 1 and the female connector 101 can be locked only by engaging the ear part 21 of the connection part 11 and the wide part 113 of the frame body 111, a device such as a lock mechanism is provided in a special manner. Therefore, the manufacture of the seat connector is facilitated, the configuration can be simplified, the cost can be reduced, and the size can be reduced.

  Further, the end portion of the ear portion 21 includes a male side step portion 23, the end portion of the wide portion 113 includes a female side step portion 123, and the male side step portion 23 and the female side step portion 123 are engaged with each other to form a male connector. 1 and the female connector 101 are locked. Thereby, the fitting state of the male connector 1 and the female connector 101 is reliably maintained.

  Further, the ear 21 includes a locking recess 56a, and the ear receiving recess 121 includes a locking projection 156a. When the end of the ear 21 and the end of the wide portion 113 are engaged, the locking projection 156a. Locks the locking recess 56a and makes the connecting portion 11 non-slidable. Thereby, even if external force or vibration is received, the connecting portion 11 does not slide in the anti-lock direction and the lock is not released, so that the male connector 1 and the female connector 101 are fitted. Is maintained. In addition, since the locking convex portion 156a locks the locking concave portion 56a, the operator can perceive a click feeling and know that the fitting is completed, so that a so-called erroneous fitting can be prevented. it can.

  Further, the ear portion 21 includes an insertion convex portion 56 that protrudes from the surface on which the protruding terminal 53 of the connection portion 11 is disposed, the ear accommodating concave portion 121 includes an insertion concave portion 156, and the insertion convex portion 56 is within the insertion concave portion 156. In a state of entering, the connecting portion 11 is slid. Thereby, since the insertion convex part 56 of the ear | edge part 21 slides and guides in the state which entered the insertion recessed part 156 of the ear | edge accommodation recessed part 121, the attitude | position of the male connector 1 with respect to the female connector 101 is not disturbed.
