Description

  The present invention relates to a relay connector.

  Conventionally, in order to electrically connect a pair of parallel circuit boards, a board-to-board connector has been used (for example, refer to Patent Document 1). Such a board-to-board connector connects a pair of circuit boards arranged side by side on the same surface.

  FIG. 12 is a side view of a conventional board-to-board connector.

  In the figure, 901 is a first connector attached to the first circuit board 991A, 902 is a second connector that fits (mates) with a mating connector attached to the second circuit board 991B, and 801 is the first connector. This is a connection connector that connects 901 and the second connector 902. The first connector 901 includes a housing 911 and a solder tail 961 protruding from the housing 911, and the solder tail 961 is connected to a corresponding conductive trace on the first circuit board 991A. Accordingly, the first connector 901 is mounted on the first circuit board 991A.

  The second connector 902 includes a housing 912 and a contact portion 962 attached to the housing 912, and fits with a mating connector mounted on the second circuit board 991B. As a result, the contact portion 962 is brought into contact with the mating terminal of the mating connector.

  The connection connector 801 includes a housing 811 and is rotatably connected to the first connector 901. In this case, the rotation shaft pins 915 formed on both sides of the housing 911 of the first connector 901 are rotatably fitted in the receiving grooves 813 formed in the housing 811 of the connection connector 801. The housing 912 of the second connector 902 is fixed to the housing 811 of the connection connector 801.

  The connection connector 801 includes a plurality of jumper leads 861 arranged in parallel. The jumper lead 861 is made of a conductive metal wire having flexibility, and both ends thereof are connected to the solder tail 961 and the contact portion 962, respectively. That is, the solder tail 961 of the first connector 901 and the contact portion 962 of the second connector 902 are connected by the jumper lead 861.

  The conventional board-to-board connector has such a structure. In a state of storage, transportation, etc., the first connector 901 is mounted on the first circuit board 991A, and the second connector 902 and the counterpart connector are connected to each other. The fitting is released. Therefore, even if the relative positions of the first circuit board 991A and the second circuit board 991B are shifted due to an external impact or the like, the stress caused by the first circuit board 991A and the second circuit board 991B is not received. When connecting the first circuit board 991A and the second circuit board 991B, the connection connector 801 is rotated with respect to the first connector 901 mounted on the first circuit board 991A, and the second connector 902 is rotated. Is mated with the mating connector mounted on the second circuit board 991B. Thereby, since the contact part 962 contacts the other party terminal of the other party connector, the first circuit board 991A and the second circuit board 991B are connected, that is, connected to the electric circuit provided on each circuit board.

Further, even if a positional shift occurs between the first circuit board 991A and the second circuit board 991B in a state where they are connected by the board-to-board connector, the fitting state between the rotation shaft pin 915 and the receiving groove 813 is not changed. In addition to being loose, the jumper lead 861 is flexible and can be flexed (bent) easily, so that the misalignment can be appropriately absorbed.

  However, in the conventional board-to-board connector, the connection connector 801 includes a plurality of jumper leads 861, and the plurality of jumper leads 861 are integrated with a housing 811 made of synthetic resin or the like. Therefore, in order to manufacture the connection connector 801, a metal terminal mold having a function of holding the jumper lead 861 as a metal terminal is used, and the metal terminal mold is filled with a molten resin. Although it is necessary to mold the housing 811, the metal terminal mold is generally expensive because it has a complicated structure, and thus the manufacturing cost of the connection connector 801 is increased.

  Further, since the jumper lead 861 is bent when a positional deviation occurs between the first circuit board 991A and the second circuit board 991B, it is bent especially when the pitch of the jumper lead 861 is narrow. At this time, adjacent jumper leads 861 come into contact with each other, so that there is a high possibility that a so-called inter-electrode short circuit occurs. For this reason, it is necessary to separately prepare an inter-electrode short-circuit countermeasure component for preventing contact between adjacent jumper leads 861, increasing the number of components and complicating the configuration.

  However, FPC (Flexible Printed Circuit: Flexible Circuit Board) and FFC (Flexible Flat Cable: Flexible Flat Cable) are flexible, so they can be used for high-speed transmission instead of the conventional board-to-board connector. It is also conceivable to connect the first circuit board 991A and the second circuit board 991B by the FPC or FFC for use. However, in this case, both ends of the flexible FPC and FFC have to be connected to the connectors mounted on the first circuit board 991A and the second circuit board 991B in order, which takes time and effort.

  The present invention solves the above-mentioned conventional problems, and fits into the mating connector mounted by forming a conductive pattern on the surface of the main body part that is integrally formed of an insulating material and that exhibits a floating function. Work can be easily performed, the displacement of the mating connector can be absorbed, no short-circuit can occur, the desired conductive pattern can be easily formed, and the configuration is simple An object of the present invention is to provide a relay connector having a small number of parts, easy to manufacture, and low in cost.

  For this purpose, in the relay connector of the present invention, a plurality of fitting portions each fitted to the mating connector are provided, a main body portion integrally formed of an insulating material, and a conductive pattern formed on the surface of the main body portion. The main body portion includes a floating mechanism portion that absorbs the displacement of the fitting portion, and the conductive pattern comes into contact with a counterpart terminal of the counterpart connector to connect a plurality of counterpart connectors.

  In another relay connector of the present invention, the main body portion further includes a first floating mechanism portion that absorbs a vertical displacement of the fitting portion and a second floating mechanism portion that absorbs a lateral displacement. The fitting part is connected to the bridging part at both ends of the bridging part in the direction in which the conductive pattern extends, and extends in the longitudinal direction.

  In still another relay connector of the present invention, the first floating mechanism portion is made of a thin plate bent in the extending direction of the conductive pattern in the bridging portion.

  In still another relay connector of the present invention, the second floating mechanism part further includes a conductive pattern holding part extending in a direction in which the conductive pattern extends in the bridging part, and the conductive pattern holding part is A plurality of comb teeth separated by second slits extending in a direction in which the conductive pattern extends in the bridging portion, and each of the conductive patterns is formed on the back surface of each of the comb teeth. The

  In still another relay connector of the present invention, the second floating mechanism portion further includes side wall portions disposed on both sides of the conductive pattern holding portion with a first slit interposed therebetween.

  In still another relay connector of the present invention, the conductive pattern is further formed on the back surface of the first floating mechanism portion, the first portion formed on the back surface of the first floating mechanism portion, and the first portion. And a third part formed on the rear surface of the fitting part and connected to the second part.

  According to the present invention, the relay connector is formed integrally with an insulating material and forms a conductive pattern on the surface of the main body that exhibits a floating function. As a result, it is possible to easily engage the mating connector mounted on the board, absorb the misalignment of the mating connector, and prevent a short circuit between the electrodes. It can be formed easily, the structure can be simplified, the number of parts can be reduced, the manufacturing can be facilitated, and the cost can be reduced.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  In the figure, reference numeral 1 denotes a connector as a relay connector in the present embodiment, a main body portion 11 formed of an insulating material such as a synthetic resin, and a conductive material described later formed on the surface of the main body portion 11. The first substrate 91A and the second substrate 91B can be electrically connected by fitting the mating connector 101 having both ends of the pattern 61 on the first substrate 91A and the second substrate 91B. it can. The conductive pattern 61 is not formed on the first surface of the main body 11, that is, the front surface 2, but is formed on the second surface of the main body 11, that is, the back surface 3. In addition, the first substrate 91A and the second substrate 91B are, for example, printed circuit boards, but may be any type of board as long as the board includes an electrical circuit.

  In the present embodiment, expressions indicating directions such as upper, lower, left, right, front, rear, etc. used for explaining the configuration and operation of each part included in the connector 1 and other members are absolute. It is not a typical one but a relative one, and is appropriate when the parts included in the connector 1 and other members are in the posture shown in the figure. However, when the posture changes, the posture changes. It should be interpreted accordingly.

  The main body 11 is integrally formed of an insulating material such as a synthetic resin, more specifically, a medium for wearing an electroless plating rod and a composite material of a thermoplastic resin containing an organic metal. It is a member, is rectangular when viewed from the top, and is corrugated plate-shaped bridging portion 12 when viewed from the front, and the base ends are connected to both ends of the bridging portion 12, and the vertical direction (downward direction in FIG. 2) It has the leg part 13 as a fitting part extended to. Further, a plurality of conductive patterns 61 extending in the direction of connecting the leg portions 13 on both sides are formed on the back surface 3 of the main body portion 11 so as to be parallel to each other.

  Then, when the leg portions 13 on both sides are fitted to the mating connectors 101 mounted on the first board 91A and the second board 91B, the conductive pattern 61 comes into contact with the mating terminals 161 of the mating connector 101. Accordingly, the counterpart terminal 161 of the counterpart connector 101 mounted on each of the first substrate 91A and the second substrate 91B is electrically connected via the conductive pattern 61.

  Here, the mating connector 101 is a receptacle connector, and includes a housing 111 as a connector body integrally formed of an insulating material such as a synthetic resin, and a conductive metal mounted on the housing 111. It has a plurality of counterpart terminals 161 and a nail 181 as an auxiliary fitting for attachment attached to both ends of the housing 111. Further, the housing 111 has an insertion opening 122 which is an opening for inserting the tip portion of the leg portion 13 of the connector 1. The insertion opening 122 has a narrow slot shape, and the dimension in the short side direction is approximately the same as the thickness dimension of the distal end portion of the leg portion 13. The periphery of the insertion opening 122 is defined by the first side wall 112, the second side wall 113, and the end wall 114.

  The first side wall 112 is a wall member that is erected so as to be substantially perpendicular to the surfaces of the first substrate 91A and the second substrate 91B, and extends in the width direction of the connector 1, and is formed on the inner wall surface. A plurality of counterpart terminals 161 arranged in the width direction of the connector 1 are mounted. The counterpart terminal 161 is exposed below the housing 111 and corresponds to the arrangement of the tail portion 163 connected to the conductive traces (not shown) provided in the first substrate 91A and the second substrate 91B and the conductive pattern 61 of the connector 1. And contact portions 164 that are in contact with the corresponding conductive patterns 61.

  The second side wall 113 is a wall member facing the first side wall 112 and extending in parallel with the first side wall 112, and a bulging part 115 as a counterpart locking part is provided near the center near the upper end. Is formed. The bulging portion 115 accommodates a locking arm portion 15 as a locking portion of the connector 1, and the locking projection 16 of the locking arm portion 15 has a locking opening 116 formed on the wall surface of the bulging portion 115. Engage with.

  Further, the end wall 114 is connected to both ends of the first side wall 112 and the second side wall 113, and is erected so as to be substantially perpendicular to the surfaces of the first substrate 91A and the second substrate 91B. The nail 181 is attached.

  The counterpart connector 101 is a so-called straight-type connector, and is in a state of being erected with respect to the surfaces of the first substrate 91A and the second substrate 91B, that is, in a state where the insertion opening 122 faces upward. The nail 181 and the tail portion 163 of the counterpart terminal 161 are fixed to the surface of the second substrate 91B by means of soldering or the like. The connector 1 has the distal end portion of the leg portion 13 inserted into the insertion opening 122, the locking arm portion 15 is accommodated in the bulging portion 115, and the locking protrusion 16 engages with the locking opening 116. The mating connector 101 is fitted and locked. As a result, each of the conductive patterns 61 of the connector 1 comes into contact with the corresponding contact portion 164 of the counterpart terminal 161 to be conductive, and the conductive traces of the first substrate 91A and the second substrate 91B to which the tail portion 163 is connected are electrically connected. Connected.

  The connector 1 in the present embodiment is a so-called MID (Molded Interconnect Device), and a conductive pattern 61 that is a three-dimensional pattern is integrally formed by plating on the surface of the main body 11 made of synthetic resin or the like. It is a thing. In this case, for example, patterning by laser irradiation is used to form the pattern. As a pattern forming method, an insulating layer is deposited on the surface of a resin molded body containing a medium for electroless plating, and the insulating layer is irradiated with a laser beam to remove the insulating layer into a circuit pattern shape. There is a method in which electroless plating is attached to the insulating layer removal portion of the molded body. In addition, various methods such as patterning by irradiating a laser on the surface of a composite material in which a filler and an organic metal are mixed in a base polymer that is a thermoplastic resin have been developed, and the description thereof is omitted here. By patterning by these laser irradiations, for example, about 80 conductive patterns 61 arranged at a fine pitch of about 100 [μm] can be obtained. Since the conductive pattern 61 is formed along the three-dimensional back surface of the main body 11, it has a three-dimensional shape as will be described later.

  The shape of the main body 11 is the longitudinal direction, that is, the direction connecting the counterpart connector 101 mounted on the first substrate 91A and the counterpart connector 101 mounted on the second substrate 91B (lateral direction in FIGS. 2 and 3). It is line symmetric with respect to an imaginary line passing through the center. That is, the main body 11 has a symmetrical shape in FIGS. And the bridge | bridging part 12 is provided with the substantially W-shaped front shape, as FIG. 3 shows, and the center part 31 as a 1st floating mechanism part, and the 2nd connected to the both sides of this center part 31 It has the side part 21 as a floating mechanism part.

  The central portion 31 is made of a flexible thin plate bent so as to have a front shape with an inverted V shape, and is mainly perpendicular to the surfaces of the first substrate 91A and the second substrate 91B by elastic deformation. The floating function in the direction, that is, the vertical direction (vertical direction in FIG. 3) is exhibited. Specifically, it absorbs displacement in the height direction between the leg portions 13 connected to both ends of the bridging portion 12, that is, in a direction perpendicular to the surfaces of the first substrate 91A and the second substrate 91B. The expansion and contraction of the distance between the leg portions 13 and the twist (twist) between the leg portions 13 are also absorbed.

  Each of the side portions 21 is formed of a substantially flat plate-like thick plate, has a plurality of vertical slits extending in the longitudinal direction and penetrating in the plate thickness direction, and is elastically deformed. As a result, a floating function mainly in the direction parallel to the surfaces of the first substrate 91A and the second substrate 91B, that is, in the lateral direction (vertical direction in FIG. 2) is exhibited. Specifically, the side portion 21 includes a conductive pattern holding portion 23 disposed at the center in the width direction, side wall portions 22 as connecting portions disposed on both sides of the conductive pattern holding portion 23, and It has the 1st slit 24 as a vertical slit formed between the conductive pattern holding | maintenance part 23 and the side wall part 22. As shown in FIG. The conductive pattern holding part 23 has a plurality of comb teeth 25 and a second slit 26 as a vertical slit formed between adjacent comb teeth 25. And the said side part 21 absorbs the displacement to the width direction (up-down direction in FIG. 2) of the leg parts 13. FIG.

  Here, the bridging portion 12 is formed so that the side portions 21 are provided on both sides with the central portion 31 interposed therebetween, but this is an intermediate portion so that the adjacent comb teeth portions 25 of the conductive pattern holding portion 23 do not contact each other. This is to maintain the interval. Therefore, when the length of the comb tooth portion 25 is short, it may be provided between the conductive pattern holding portion 23 and the leg portion 13.

  Next, the configuration of the connector 1 will be described in detail.

  5 is a perspective view of the relay connector according to the embodiment of the present invention as viewed from above, FIG. 6 is a perspective view of the relay connector as viewed from below according to the embodiment of the present invention, and FIG. 7 is according to the embodiment of the present invention. FIG. 8 is a bottom view of the relay connector in the embodiment of the present invention, FIG. 9 is a side view of the relay connector in the embodiment of the present invention, and FIG. 10 is a relay connector in the embodiment of the present invention. FIG. 11 is a cross-sectional view of the relay connector in the embodiment of the present invention, and is a cross-sectional view taken along the line ZZ in FIG.

  As shown in FIGS. 6 and 8, the plurality of conductive patterns 61 are formed on the back surface 3 of the main body 11 of the connector 1, and each extend in the direction connecting the legs 13 on both sides, that is, in the longitudinal direction. At the same time, they are arranged in the width direction. Each conductive pattern 61 is formed on the back surface of the comb tooth portion 25 of the conductive pattern holding portion 23 in the first portion 62 formed on the back surface of the central portion 31 of the bridging portion 12 and the side portions 21 on both sides of the central portion 31. The second portion 63 and the third portion 64 formed on the back surface of the leg portion 13 are provided. Each conductive pattern 61 is formed so as to be continuous from the end of one third portion 64 to the end of the other third portion 64 without interruption.

  Here, as described above, each comb-tooth portion 25 is a thin plate-like member that is separated from the adjacent comb-tooth portion 25 by the second slit 26 that penetrates the side portion 21 in the plate thickness direction and is independent. The dimension of the width direction of the part 21 is very small. That is, the cross-section of each comb tooth portion 25 has a rectangular shape in which the dimension in the width direction of the side portion 21 is extremely short with respect to the dimension in the plate thickness direction of the side portion 21. Therefore, each comb tooth portion 25 has a cross-sectional secondary coefficient in the width direction that is extremely smaller than a cross-sectional secondary coefficient in the plate thickness direction, so that it can be flexibly deformed in the width direction, and a plurality of combs arranged in parallel. The conductive pattern holding part 23 which is an aggregate of the tooth parts 25 can also be deformed relatively flexibly in the width direction.

  One second portion 63 of the conductive pattern 61 is formed on the back surface of each comb tooth portion 25. That is, the comb-tooth portions 25 are arranged in the width direction at a pitch equivalent to the arrangement pitch of the conductive patterns 61.

  In addition, the side wall part 22 disposed with the first slits 24 sandwiched on both sides in the width direction of the conductive pattern holding part 23 is substantially the same as that of the comb tooth part 25 in the thickness direction of the side part 21. The dimension of the side part 21 in the width direction is larger than that of the comb tooth part 25 as shown in FIGS. Therefore, the side wall portion 22 has a small cross-sectional secondary coefficient in the width direction to some extent and can be deformed to some extent in the width direction, but is not as flexible as the comb tooth portion 25. By adjusting the dimension of the side wall portion 22 in the width direction, the flexibility of the side portion 21 can be adjusted and the strength of the side portion 21 can be maintained. In this respect, the dimension in the width direction of the side wall 22 can be selected as appropriate, and the side portion 21 can be constituted by only the comb tooth portion 25.

  In addition, since the said side wall part 22 and the comb-tooth part 25 have a large dimension of a plate | board thickness direction and a cross-sectional secondary coefficient of a plate | board thickness direction is large, it is hard to deform | transform in a plate | board thickness direction.

  Thus, since the side part 21 is isolate | separated into the some side wall part 22 and the comb-tooth part 25 by the vertical slit, it has a flexibility in the width direction and absorbs the displacement to the width direction of leg parts 13 mutually. can do. As shown in FIGS. 7 and 8, the side portion 21 has a conductive pattern holding portion 23 in a rectangular frame formed by the side wall portion 22, the leg portion 13, and the central portion 31 on both sides. It has a shape that is housed. And when the side part 21 deform | transforms in the width direction and absorbs the displacement to the width direction of the leg parts 13, the said rectangular frame deform | transforms into a parallelogram, and the leg part 13 becomes the center part 31. Is displaced in the width direction. In this case, since both ends of each comb tooth portion 25 are connected to the leg portion 13 and the central portion 31 and move in parallel, the adjacent comb tooth portions 25 do not contact each other. Therefore, even if the side portion 21 is deformed in the width direction, a short circuit due to contact between the second portions 63 of the adjacent conductive patterns 61 does not occur.

  Further, when the width of the conductive pattern 61 is smaller than the width of the comb tooth portion 25 at the center of the comb tooth portion 25 at the side portion 22, the comb tooth portions 25 are formed on both sides of the conductive pattern 61. Resin is arranged. If it does so, even if the adjacent comb-tooth parts 25 will contact by some forcing force, or will contact by unintentional deformation | transformation etc., the adjacent conductive patterns 61 will not contact.

  The central portion 31 includes a ridge portion 33 located at the center in the longitudinal direction, slope portions 32 connected to both sides of the ridge portion 33, and a heel portion 34 connected to the slope portion 32. Is provided. The ridge portion 33 is a portion of a ridge that has a protruding shape formed of a curved surface protruding upward when viewed from the front, and extends in the width direction. The inclined surface portion 32 is a flat plate-like portion that is inclined downward from the ridge portion 33 toward the flange portion 34 and extends in the width direction. Further, the flange portion 34 is a flat and flat portion extending in the width direction, and an end portion on the opposite side to the slope portion 32 is connected to the side portion 21. The ridge portion 33, the slope portion 32, and the flange portion 34 are connected so as to draw a gently curved surface, as shown in FIG. Or a front shape is provided.

  Thus, since the central portion 31 is a member shaped like a flexible thin plate bent in the longitudinal direction, the sectional secondary coefficient in the width direction is large and the sectional secondary coefficient in the thickness direction is small. It can be flexibly deformed in the thickness direction. Therefore, flexibility is provided in the vertical direction, and the displacement in the vertical direction between the leg portions 13 can be absorbed. Further, since the central portion 31 has a shape that is bent in the longitudinal direction, the central portion 31 also has stretchability in the longitudinal direction. Therefore, the center portion 31 absorbs expansion and contraction of the distance between the leg portions 13 and also allows torsion. Absorbs twists between each other.

  As shown in FIGS. 6 and 11, the back surface 3 of the main body 11 of the connector 1 is formed smoothly and continuously. Specifically, the back surface of the central portion 31 is formed so that the connection portion of each portion draws a gentle curved surface, and the connection portion with the side portion 21 is also formed to be a flat surface. Yes. Further, the back surface of the side portion 21 is formed by a flat surface and a gently curved surface connecting the flat surfaces. And the back surface of the leg part 13 has a flat vertical wall surface 13a extending in the vertical direction, a gently curved connection curved surface 13b formed at the connection part between the vertical wall surface 13a and the back surface of the side part 21, A chamfered portion 13c, which is an inclined flat surface formed at the tip of the vertical wall surface 13a, that is, the lower end, is provided.

  Thus, since the back surface 3 of the main body part 11 is smoothly continuous, the angle change in each part of the conductive pattern 61 formed by plating is smooth, and the conductive pattern 61 is not interrupted in the middle.

  If there is a discontinuous part or a part in which the angle changes abruptly on the back surface 3 of the main body part 11, the plating film may be interrupted at such a part when the plating film is formed. Furthermore, the plating film formed in such a part will be easily cut | disconnected if it contacts or rubs another member. Also, when patterning is performed by irradiating with a laser, if there are discontinuous portions or portions where the angle changes abruptly, the pattern may be interrupted at such portions.

  However, in the present embodiment, there is no discontinuous portion or portion where the angle changes abruptly on the back surface 3 of the main body portion 11, so that the pattern is not interrupted when patterning is performed by laser irradiation. In addition, the plating film is not interrupted when the plating film is formed. Furthermore, even if the formed plating film contacts or rubs against other members, it is not cut. Therefore, a continuous and stable conductive pattern 61 without interruption can be obtained.

  The connecting portion between the vertical wall surface 13a and the back surface of the side portion 21 is a portion having an acute shape whose angle changes abruptly as a whole, but a gently curved connecting curved surface 13b is formed. The pattern is not interrupted when patterning is performed by irradiating and the plating film is not interrupted when the plating film is formed.

  In particular, when patterning is performed by irradiating a laser, the connecting portion between the vertical wall surface 13a and the back surface of the side portion 21 has an acute angle and is sandwiched between the vertical wall surface 13a and the back surface of the side portion 21. If it is left as it is, it is difficult for the laser to reach, and there is a high possibility that the pattern on the vertical wall surface 13a and the pattern on the back surface of the side portion 21 are not properly connected. However, since the gently curved connection curved surface 13b is formed, the laser can easily reach and both patterns are appropriately connected. Since the back surface of the ridge portion 33 of the central portion 31 is also gently curved like the connection curved surface 13b, the laser is easy to reach and the patterns on the back surfaces of the slope portions 32 on both sides are appropriately connected.

  Further, since the chamfered portion 13 c is formed at the tip of the vertical wall surface 13 a, when the connector 1 is fitted with the mating connector 101, the tip portion of the leg portion 13 is smoothly inserted into the insertion opening 122 of the mating connector 101. It becomes possible to insert. Further, when the third portion 64 of the conductive pattern 61 comes into contact with the corresponding contact portion 164 of the counterpart terminal 161, first, the vicinity of the terminal end of the third portion 64 that contacts the contact portion 164 of the counterpart terminal 161 is inclined plane. Since it is formed on the chamfered portion 13c, it is difficult to cut. Therefore, the entire third portion 64 is not cut when contacting the contact portion 164 of the counterpart terminal 161. The chamfered portion 13c may be a curved surface that gradually changes in inclination instead of an inclined plane.

  Further, a cantilever-like locking arm 15 is integrally formed on the surface of the leg 13. As shown in FIG. 11, the lower end of the locking arm 15 is connected to the surface of the leg 13 and the upper end is a free end, which is an operation unit operated by a finger or the like. A locking protrusion 16 is formed in the middle of the locking arm 15.

  Further, end wall portions 14 are connected to both ends of the leg portion 13 in the width direction. With respect to the longitudinal direction of the main body part 11, the end wall part 14 is larger in dimension than the leg part 13. Therefore, when the end wall portion 14 is connected, the sectional secondary coefficient in the longitudinal direction of the main body portion 11 in the entire leg portion 13 is increased, and the rigidity of the entire leg portion 13 is improved. In other words, the leg portion 13 is composed of a plate member extending in the vertical direction, so that the rigidity is not sufficient as it is, but the end wall portion 14 having a dimension in the plate thickness direction larger than the leg portion 13 at both ends in the width direction.

Is done.

  If the first board 91A and the second board 91B are arranged in advance so that each counterpart connector 101 is in a predetermined direction at a predetermined position, the bridging portion 12 as a whole has high rigidity in the vertical direction. Since it is difficult to be deformed, the leg portions 13 at both ends can be fitted to both the mating connectors 101 simultaneously by one operation by grasping and moving the bridging portion 12 with fingers or the like.

  Then, the locking projection 16 of the locking arm 15 is engaged with the locking opening 116 formed on the wall surface of the bulging portion 115 of the counterpart connector 101, so that the leg portion 13 is engaged with the counterpart connector 101.

A plurality of counterpart connectors 101 are connected in contact with the terminal 161. Thereby, although the number of parts is small and the configuration is simple, it is possible to absorb the misalignment between the counterpart connectors 101. Moreover, the operation | work which fits the leg part 13 to the other party connector 101 can be performed easily. Furthermore, a desired conductive pattern 61 can be easily formed, and manufacturing is easy, and cost can be reduced.

  The main body 11 includes a central portion 31 that exhibits a floating function that absorbs a displacement in the vertical direction and a side portion 21 that exhibits a floating function that absorbs a displacement in the horizontal direction. The leg part 13 is connected to the bridging part 12 at both ends of the bridging part 12 in the direction in which the conductive pattern 61 extends, and extends in the vertical direction. As described above, the bridging portion 12 is formed separately from the central portion 31 that exhibits the floating function that absorbs the displacement in the vertical direction and the side portion 21 that exhibits the floating function that absorbs the displacement in the horizontal direction. While maintaining flexibility, it has a certain degree of rigidity. Therefore, the leg portions 13 connected to both ends can be collectively fitted to the counterpart connector 101.

  Further, the central portion 31 is formed of a thin plate bent in the extending direction of the conductive pattern 61 in the bridging portion 12. Thereby, the center part 31 can also absorb the expansion / contraction of the distance between the leg parts 13 and the twist of the leg parts 13 in addition to the said vertical direction.

  Further, the side portion 21 includes a plurality of comb teeth portions 25 separated by the second slits 26 in the conductive pattern holding portion 23, and each of the conductive patterns 61 is formed on the back surface of each of the comb teeth portions 25. Yes. Thereby, the displacement in the horizontal direction of the leg portions 13 can be absorbed without causing a short circuit due to contact between the adjacent conductive patterns 61 without contact between the comb tooth portions 25.

  Further, the side portion 21 includes a conductive pattern holding portion 23 and side wall portions 22 disposed on both sides of the conductive pattern holding portion 23 with a first slit 24 interposed therebetween. Thereby, the side part 21 can absorb the displacement to the horizontal direction of leg parts 13, maintaining the rigidity.

  Further, the conductive pattern 61 is formed on the back surface of the central portion 31, the second portion 63 formed on the back surface of the side portion 21 and connected to the first portion 62, and the back surface of the leg portion 13. And a third part 64 connected to the second part 63.
