Description

  The present invention relates to a pedestal connector in which a plurality of board terminals connected to conductive paths of a printed circuit board are fixed to the pedestal.

  2. Description of the Related Art Conventionally, a printed circuit board used for an electric junction box of an automobile has used a pedestal connector in which a plurality of board terminals are fixed to the pedestal so as to be connected to an external electrical component. For example, what is shown in FIG. 3 of Unexamined-Japanese-Patent No. 2008-35669 (patent document 1) is it.

  By the way, such a base connector is fixed to the base by press-fitting a board terminal connected to the conductive path of the printed board into an insertion hole penetrating the base. In recent years, with the further miniaturization and higher density of electrical components and electrical circuits, the use of pedestal connectors in which board terminals with smaller cross-sectional areas are arranged at a narrow pitch is increasing.

  However, the operation of press-fitting the board terminal into the pedestal is very complicated because it needs to be pressed using a jig, and improvement of work efficiency has been demanded. In particular, in the case of a substrate terminal having a small cross-sectional area, the work is made more difficult because the work becomes finer and more complicated due to a narrow pitch, and buckling deformation tends to occur during press-fitting.

JP 2008-35669 A

  The present invention has been made in the background of the above-mentioned circumstances, and a solution to that problem is a pedestal connector having a novel structure capable of fixing a board terminal to the pedestal without requiring press-fitting into the pedestal. Is to provide.

  A first aspect of the present invention is a pedestal connector in which a plurality of board terminals are fixed in a penetrating state to a synthetic resin pedestal, while a bent portion is formed at a middle portion in the length direction of the board terminal, The pedestal is formed by a divided structure composed of a main body member placed on the substrate and a cover member superimposed on the main body member, and the substrate terminal is disposed between the overlapping surfaces of the main body member and the cover member. The bent portion is sandwiched and fixed in position.

  According to the base connector having the structure according to the present invention, the board terminal can be fixed to the base without requiring press-fitting by holding the bent portion of the board terminal between the main body member and the cover member. . Thereby, the possibility of buckling deformation or the like that may occur when the board terminal is press-fitted into the base can be avoided.

  According to a second aspect of the present invention, in the one described in the first aspect, the board terminal has a crank shape in which the bent portion extends perpendicular to any of the extending directions of both end portions. The bent portion is sandwiched between the main body member and the cover member from both sides in the extending direction of the both end portions.

  According to this aspect, since the board terminal has a crank shape, the stress due to the thermal expansion of the pedestal can be relieved at the crank portion. Thereby, generation | occurrence | production of a solder crack can be suppressed.

  Furthermore, since the bent portion is sandwiched between the main body member and the cover member from both sides in the extending direction of the end portion, the main body member can receive the force in the pushing direction exerted on the board terminal when the mating connector is connected. At the same time, the force in the pulling direction exerted on the board terminal when the mating connector is detached can be received by the cover member. As a result, the stress exerted on the soldering portion when the mating connector is inserted and removed can be reduced, and the occurrence of solder cracks can be more effectively suppressed.

  A third aspect of the present invention is the one described in the second aspect, wherein a plurality of the board terminals protrude from the pedestal in parallel with each other and are arranged in two rows, and the board terminals in each row. Are bent toward the opposite side of the other row.

  If it does in this way, the edge part extended toward a printed circuit board from a bent part in a substrate terminal will be spaced apart outward from a base, and will be soldered to a printed circuit board in the position spaced apart from the base. Thereby, the possibility that the visibility of the soldering portion is hindered by the pedestal can be reduced, and the visibility of the soldering portion can be improved.

  Further, the bent portions of the board terminals in each row are projected to the opposite sides, so that the end portions on the printed board side extending from the bent portions can be positioned apart from the pedestal. As a result, a larger space for forming the leg portion on the printed circuit board in the base can be secured, and the leg portion can be formed larger. As a result, it is possible to improve the support strength of the pedestal for the connection of the counterpart connector.

  According to a fourth aspect of the present invention, in the one according to any one of the first to third aspects, the cover member covers the main body member in a state of covering the surface of the main body member on the protruding side of the substrate terminal. And the board terminal protrudes from the main body member through an insertion hole formed in the cover member.

  According to this aspect, the board terminal can be more stably held by being inserted into the insertion hole. In particular, when the direction in which the cover member is superimposed on the main body member is the same direction as the mating connector insertion / extraction direction, the board member is more reliably secured by the cover member against the external force exerted on the board terminal when the mating connector is pulled out. Can be held. And since the positioning precision to the base of a some board | substrate terminal is improved, the pitch between terminals and the insulation between terminals can be ensured more stably.

  According to a fifth aspect of the present invention, in the one described in any one of the first to fourth aspects, a fitting groove is formed in at least one of the overlapping surfaces of the main body member and the cover member. The bent portion of the board terminal is fitted into the fitting groove.

  According to this aspect, it is possible to position the substrate terminal with higher accuracy by fitting the board terminal into the fitting groove. Thereby, the pitch between terminals and terminal insulation can be secured more stably. Moreover, the assembly | attachment operation | work to the base of a board | substrate terminal can be made easy.

  According to a sixth aspect of the present invention, in the above-described fifth aspect, the fitting groove is formed in an outer peripheral portion of the overlapping surface of the main body member with the cover member. One end of the fitting groove is opened on the projecting end surface of the central projection formed to project at the central portion of the overlapping surface, and the cover member has an opening shape corresponding to the central projection. A through hole is formed, and when the main body member and the cover member are overlapped with each other, the central protrusion is inserted into the through hole, and the protruding end surface is opposite to the printed circuit board through the through hole. And the peripheral portion of the through hole in the cover member is overlapped with the outer peripheral portion of the overlapping surface of the main body member in which the fitting groove is formed. A.

  According to this aspect, the body member and the cover member can be easily aligned by fitting the cover member to the central protrusion of the body member. In addition, since the protruding end surface of the central protrusion of the main body member is exposed through the cover member, the pressing force for connecting the mating connector can be directly received by the main body member placed on the printed circuit board. , More stable support force can be obtained.

  Moreover, according to this aspect, the fitting groove into which the board terminal is fitted can be formed only in the main body member. As a result, the dimensional accuracy of the fitting groove is impaired due to a dimensional error between the body member and the cover member, as in the case where the fitting groove is partially formed and combined with each of the body member and the cover member. The fear can be reduced, and the fitting groove can be formed with high dimensional accuracy. As a result, the positioning accuracy of the substrate terminal can be improved.

  According to a seventh aspect of the present invention, in the above-described fifth aspect, the fitting groove is formed on an overlapping surface of the cover member with the main body member, and the cover member includes A terminal insertion hole through which the end of the board terminal opposite to the printed board is inserted in a loosely inserted state, and one end of the fitting groove is connected to the terminal insertion hole, The cover member is opened to the surface of the cover member opposite to the printed board through the terminal insertion hole, and the main body member is overlapped with the cover member as a single flat surface.

  According to this aspect, it is possible to position the substrate terminal with higher accuracy by inserting the board terminal into the terminal insertion hole. In addition, since both the fitting groove and the terminal insertion hole are formed in the cover member, it is possible to avoid displacement of the fitting groove and the terminal insertion hole, and the positioning of the board terminal to the base is more accurate. Can be done. Furthermore, since the overlapping surface of the main body member on the cover member is a single flat surface, the shape of the main body member can be made simpler and easily formed.

  According to an eighth aspect of the present invention, in the one described in any one of the first to seventh aspects, the substrate terminal is configured by a wire terminal formed by cutting a metal wire with a predetermined length. It is what.

  That is, since the wire terminal has a small cross-sectional area and is fragile, buckling deformation may occur when the wire terminal is press-fitted into the base and fixed. However, according to the present invention, since the board terminal can be fixed to the pedestal without press-fitting, it is possible to avoid the risk of buckling deformation during press-fitting, and the pedestal connector provided with the board terminal having a small cross-sectional area. Can be realized with good quality.

  According to the present invention, the pedestal is configured as a divided structure of the main body member and the cover member, and the substrate terminal is sandwiched and fixed between the main body member and the cover member. This makes it possible to fix the board terminal to the pedestal without press-fitting, and avoid the possibility of buckling deformation that may occur during press-fitting. As a result, even a pedestal connector having a board terminal with a small cross-sectional area can be realized with high quality.

  As shown in FIG. 2, the pedestal 14 of the pedestal connector 10 according to this embodiment is a divided structure including a main body member 18 and a cover member 20. FIG. 3 shows the main body member 18. The main body member 18 is an integrally molded product made of a non-conductive synthetic resin, and a gate having a pair of leg portions 22 and 22 projecting toward the printed circuit board 12 at both end edges in the longitudinal direction. It is made into a shape. Note that the protruding tip portion of each leg portion 22 has a slightly smaller width dimension perpendicular to the longitudinal direction of the main body member 18, and the leg portion 22 has a leg portion 22 on the inner surface of the main body member 18. Reinforcing ribs 23 each having a triangular plate shape extending over the protruding tip edge are formed.

  On the upper surface of the main body member 18, an overlapping surface 24 having a substantially longitudinal rectangular shape is formed. Further, a central protrusion 26 is formed in the central portion of the overlapping surface 24 and has a substantially longitudinal rectangular cross section that is slightly smaller than the overlapping surface 24 and protrudes on the opposite side to the protruding direction of the legs 22 and 22. Yes.

  A plurality of fitting grooves 28 are formed in the outer peripheral portion of the overlapping surface 24. The fitting groove 28 opens on the overlapping surface 24, extends in the width direction perpendicular to the longitudinal direction on the overlapping surface 24, and extends from the end extending inward of the overlapping surface 24 to the center protrusion. It is L-shaped and opens on the side surface 30 of 26 and extends in the protruding direction of the central protrusion 26. Thus, one end 32 of the fitting groove 28 is opened on the side surface 34 of the main body member 18, while the other end 36 is opened on the protruding end surface 38 of the central projection 26. . The cross-sectional shape of the fitting groove 28 is a substantially square cross-sectional shape that is slightly larger than the substantially square cross-sectional shape of the board terminal 16 described later over substantially the entire length. In addition, the groove bottom surface 40 of the fitting groove 28 is a curved surface with the corners dropped at the end portions 32 and 36, and the possibility of damage to the board terminal 16 due to the biting of the corner portions is reduced. A plurality of such fitting grooves 28 are arranged on both sides of the overlapping surface 24 in the width direction with a predetermined interval in the longitudinal direction of the overlapping surface 24.

  Engaging protrusions 44 and 44 are formed on the side surfaces 42 and 42 on both ends in the longitudinal direction of the main body member 18, respectively. The engaging protrusion 44 has a block shape that protrudes from the side surface 42 outward in the longitudinal direction of the main body member 18. On the side of the overlapping surface 24 of the main body member 18 in the engaging protrusion 44, an inclined guide surface that gradually protrudes outward from the longitudinal edge of the overlapping surface 24 in the protruding direction of the leg portion 22. On the other side of the inclined guide surface 46, an engagement surface 48 that extends perpendicularly to the side surface 42 is formed.

  On the other hand, the cover member 20 is an integrally molded product formed from a non-conductive synthetic resin, and as shown in FIG. 2, both end portions in the longitudinal direction of the top plate portion 50 superimposed on the main body member 18. A pair of engaging portions 52, 52 is formed to protrude from the gate. The top plate portion 50 has a plate shape having a longitudinal dimension and a width dimension substantially equal to the overlapping surface 24 of the main body member 18. In addition, the thickness dimension of the top plate part 50 is made substantially equal to the projecting dimension from the overlapping surface 24 of the central projecting part 26 in the main body member 18.

  Further, a through hole 54 is formed in the central portion of the top plate portion 50. The through hole 54 has a substantially longitudinal rectangular cross section that is substantially equal to the protruding end surface 38 of the central protrusion 26 in the main body member 18 and extends in the thickness direction of the top plate portion 50. Thereby, the overlapping surface 56 of the cover member 20 on the main body member 18 is formed around the through hole 54 in the top plate portion 50. Further, the inner circumferential surface of the through hole 54 is sized to enter the fitting groove 28 at a position corresponding to each of the plurality of fitting grooves 28 opened in the side surface 30 of the central protrusion 26 in the main body member 18. A protrusion 57 is formed to protrude.

  Engaging portions 52 and 52 are formed at both ends of the top plate portion 50 in the longitudinal direction. The engaging portion 52 has a U-shape that opens toward the top plate portion 50. Thereby, although not necessarily clear from the drawings, through-hole-shaped window portions 58 surrounded by the top plate portion 50 and the engaging portions 52 are formed at both ends in the longitudinal direction of the cover member 20. A surface of the inner peripheral surface of the engaging portion 52 that faces the top plate portion 50 is an engaging surface 60. Further, as is apparent from the engaging portion 52 formed in the cover member 86 of the second embodiment described later and having the same shape as that of the present embodiment shown in FIG. On the surface, there is formed an inclined guide surface 61 that gradually expands outward as it goes in the protruding direction of the engaging portion 52 from the top plate portion 50.

  On the other hand, the substrate terminal 16 is shown in FIG. The substrate terminal 16 has a predetermined length of a metal wire having a plating layer made of a conductive metal material such as tin or gold deposited on the entire surface of a base material made of a conductive metal material such as copper or iron. It is a linear terminal formed by cutting at. As the cross-sectional shape of the substrate terminal 16, a rectangular shape such as a square or a rectangle, a polygonal shape, a circular shape including an ellipse, or any other shape can be appropriately employed. The substrate terminal 16 in the present embodiment has a substantially square cross section of approximately 0.5 mm × approximately 0.4 mm over substantially the entire length excluding both end edges that are tapered.

  A connection-side end 62 that extends linearly is formed at one end in the length direction of the substrate terminal 16. Further, a substrate side end portion 64 extending in parallel to the connection side end portion 62 is formed at an end portion opposite to the connection side end portion 62. In the board terminal 16, a lengthwise intermediate portion located between the connection side end 62 and the board side end 64 extends perpendicular to the connection side end 62 and the board side end 64. A bent portion 66 is formed. The bent portion 66 is formed by bending the cutting wire constituting the substrate terminal 16 by press working or the like. Thereby, the board terminal 16 has a crank shape. The length dimension of the bent portion 66 is larger than the length dimension of the fitting groove 28 in the main body member 18 on the overlapping surface 24.

  As shown in FIG. 2, the bent portion 66 of the board terminal 16 is fitted into each of the plurality of fitting grooves 28 of the main body member 18 in a non-press-fit state. Further, the cover member 20 is brought close to the main body member 18 while inserting the connection side end portion 62 of the board terminal 16 protruding from the main body member 18 into the through hole 54, and the engaging portions 52, 52 are connected to the main body member 18. The engagement protrusions 44 and 44 are fixed to the main body member 18 by fitting over the engagement protrusions 44 and 44 into the window portion 58. When the cover member 20 is assembled to the main body member 18, the inclined projection surfaces 46, 46, 61, 61 are formed on the engaging protrusions 44, 44 and the engaging portions 52, 52, respectively. , 52 is easy to get over. As shown in FIG. 1, the engagement surface 48 of the engagement protrusion 44 and the engagement surface 60 of the engagement portion 52 are opposed to each other in the extending direction of the connection side end portion 62 of the board terminal 16. The

  Thereby, the cover member 20 is assembled | attached to the main body member 18, and the base 14 is comprised. In the assembled state of the cover member 20, the central protrusion 26 of the main body member 18 is inserted into the through hole 54, and the overlapping surface 56 formed around the through hole 54 in the cover member 20 is overlapped with the main body member 18. It overlaps with the outer peripheral part of the mating surface 24. As a result, the board terminal 16 is positioned and fixed to the pedestal 14 by being sandwiched between the two overlapping surfaces 24 and 56 at the bent portion 66 fitted in the fitting groove 28. The bent portion 66 is sandwiched between the overlapping surfaces 24 and 56 from both sides in the extending direction of the connection side end portion 62 and the substrate side end portion 64.

  Then, the protruding end surface 38 of the central protrusion 26 is exposed to the outside of the pedestal 14 on the side opposite to the printed circuit board 12 through the through hole 54, so that the connection side end 62 of the board terminal 16 opens to the protruding end surface 38. The fitting groove 28 protrudes from the base 14 through one end 36. Since the plurality of fitting grooves 28 are arranged in two rows in the main body member 18, the plurality of board terminals 16 positioned in these fitting grooves 28 have the connection side end portions 62 parallel to each other and the base 14. Are arranged in two rows. In particular, in the present embodiment, the protrusion 57 projecting from the through hole 54 in the cover member 20 enters the fitting groove 28 formed in the central protrusion 26, whereby the substrate in the fitting groove 28. The terminal 16 can be positioned with higher accuracy.

  Further, the bent portion 66 of the board terminal 16 is projected outward in the width direction perpendicular to the longitudinal direction of the main body member 18 through the other end portion 32 of the fitting groove 28 opened in the side surface 34 of the main body member 18. The A board-side end 64 of the board terminal 16 extends from the protruding end of the bent part 66 that protrudes outside the base 14. Thereby, the board | substrate side edge part 64 is extended in the position spaced apart outward in the width direction of the base 14. As shown in FIG. Further, the plurality of fitting grooves 28 extend in the width direction of the overlapping surface 24 at both ends in the width direction of the overlapping surface 24 in the main body member 18, so that the bent portions of the substrate terminals 16 in each row are formed. 66 project from the bent portions 66 of the board terminals 16 in the other row on the opposite sides in the width direction of the base 14.

  Thus, the plurality of board terminals 16 are fixed to the pedestal 14 in a penetrating state in which the connection side end 62 and the board side end 64 are protruded from the pedestal 14, and the pedestal connector 10 is configured. In such a base connector 10, the main body member 18 is placed on the printed circuit board 12 by the legs 22, 22, and each board side end 64 is inserted into a through hole 68 penetrating the printed circuit board 12. Then, it is assembled to the printed circuit board 12 by being soldered. And each board | substrate side edge part 64 is electrically connected with the printed wiring (not shown) as a conductive path formed in the printed circuit board 12, and the other party connector not shown can be connected to each connection side edge part 62. .

  According to the pedestal connector 10 having such a structure, the substrate terminal 16 can be fixed to the pedestal 14 without using press-fitting by holding the substrate terminal 16 between the body member 18 and the cover member 20. Thereby, the possibility of buckling deformation at the time of press-fitting can be avoided. As a result, even a pedestal connector having linear terminals having an extremely small cross-sectional area can be realized with high quality. Furthermore, by avoiding press-fitting, it is possible to reduce the possibility of peeling off the plating layer of the substrate terminal 16 during press-fitting.

  Particularly in the present embodiment, by inserting the board terminals 16 into the fitting grooves 28 of the main body member 18, the plurality of board terminals 16 can be positioned with high accuracy, and the board terminals 16 are fitted into the fitting grooves 28. By assembling the cover member 20 in the inserted state, the assembling work can be facilitated. Further, since the fitting groove 28 is formed only in the main body member 18, problems such as unstable shape of the fitting groove due to a dimensional error between the main body member 18 and the cover member 20 can be avoided. 16 can be positioned with higher accuracy.

  In the assembled state to the printed circuit board 12, only the main body member 18 of the pedestal 14 is in contact with the printed circuit board 12 at the leg portions 22 and 22, and the cover member 20 is not in contact with the printed circuit board 12. ing. Therefore, since the thermal effect on the cover member 20 during soldering is reduced, the cover member 20 can be formed of an inexpensive synthetic resin material that does not contain glass fibers or the like. Further, in the board terminals 16 arranged in two rows, the board-side end portions 64 of both rows are positioned away from the pedestal 14 so as to be opposite to each other. It can be separated from 14, and it is possible to reduce the thermal influence on the pedestal 14 during soldering and to improve the visibility of the soldered portion. In addition, since the substrate terminal 16 has a crank shape, stress due to thermal expansion of the base 14 can be relieved at the crank portion, and the occurrence of solder cracks can also be suppressed.

  Further, the bent portion 66 of the board terminal 16 is sandwiched between the overlapping surface 24 of the main body member 18 and the overlapping surface 56 of the cover member 20 from both sides in the extending direction of the connection side end portion 62. As a result, when a mating connector (not shown) is connected to the connection-side end 62, the force in the pushing direction exerted on the board terminal 16 is applied to the overlapping surface 24 (specifically, the fitting groove) of the body member 18. 28 groove bottom surface 40). On the other hand, when the mating connector is pulled out from the connection side end 62, the pulling direction force exerted on the board terminal 16 can be received by the overlapping surface 56 of the cover member 20. As a result, the stress exerted on the board terminal 16 when the mating connector is inserted / removed can be reduced, and the occurrence of solder cracks can be more effectively suppressed.

  In particular, in the present embodiment, the board-side end portions 64 of the board terminals 16 arranged in two rows are separated from each other outward in the width direction of the base 14. Thereby, the formation space of the leg parts 22 and 22 in the main body member 18 can be ensured more, and the push-in exerted on the board terminal 16 when the mating connector is connected by securing the width dimension of the leg parts 22 and 22. It is possible to secure the supporting force against the stress in the direction more firmly. Further, since the protruding end surface 32 of the central protrusion 26 in the main body member 18 is exposed to the outside of the base 14, the stress of the mating connector can be directly received by the main body member 18, and a more stable support force can be obtained. Can be obtained. On the other hand, the engagement surface 48 of the engagement protrusion 44 in the main body member 18 and the engagement surface 60 of the engagement portion 52 in the cover member 20 face each other in the insertion / extraction direction of the counterpart connector, so that the board is removed when the counterpart connector is removed. The cover member 20 can be stably locked by the main body member 18 against the stress in the pulling direction exerted on the terminal 16 to obtain a more effective support force.

  Next, FIG. 5 shows a printed circuit board 12 provided with a base connector 80 as a second embodiment of the present invention. In the following description, the same members and parts as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment in the drawings, and the description thereof is omitted as appropriate.

  As shown in FIG. 6, the pedestal 82 of the pedestal connector 80 in the present embodiment is a divided structure including a main body member 84 and a cover member 86. FIG. 7 shows the main body member 84. Particularly, in the main body member 84 in the present embodiment, the overlapping surface 88 on which the cover member 86 is overlapped is a flat single plane.

  8 and 9 show the cover member 86. FIG. In the cover member 86, a plurality of fitting grooves 92 are formed in the overlapping surface 90 that is overlapped with the main body member 84. The plurality of fitting grooves 92 are formed in two rows at predetermined intervals in the longitudinal direction of the overlapping surface 90 on both sides of the overlapping surface 90 in the width direction orthogonal to the longitudinal direction. The fitting groove 92 has a substantially square cross section slightly larger than the substantially square cross section of the substrate terminal 16 and extends in the width direction of the overlapping surface 90, and one end 94 is a side surface of the cover member 86. 96 is opened.

  Further, in the fitting groove 92, an end 98 opposite to the end 94 is connected to a terminal insertion hole 100 that penetrates the top plate 50 of the cover member 86 in the thickness direction. The terminal insertion hole 100 has a substantially square cross section that is slightly larger than the substantially square cross section of the substrate terminal 16. Thus, the fitting groove 92 is opened through the terminal insertion hole 100 to the top surface 102 on the opposite side of the overlapping surface 90 positioned on the printed board 12 side in the top plate portion 50.

  As shown in FIG. 6, the connection side end 62 of the board terminal 16 is inserted in the loosely inserted state from the overlapping surface 90 side into the plurality of terminal insertion holes 100 of the cover member 86 having such a structure. As a result, the connection-side end portion 62 protrudes from the top surface 102 and the bent portion 66 is fitted into the fitting groove 92 in a non-press-fit state. The main body member 84 is assembled to the cover member 86 on which the board terminal 16 is set. As a result, the overlapping surface 90 of the cover member 86 is overlapped so as to cover the overlapping surface 88 of the main body member 84, and the bent portion 66 fitted into the fitting groove 92 becomes the overlapping surfaces 88, 90. Thus, the connection side end 62 is positioned and fixed by being sandwiched from both sides in the extending direction. As a result, the connection side end 62 of the board terminal 16 protrudes from the base 14 through the terminal insertion hole 100, and the bent portion 66 passes through the end portion 94 of the fitting groove 92 opened in the side surface 96 of the cover member 86. The board terminal 16 protrudes from the base 14 and is fixed to the base 14 in a penetrating state.

  According to the base connector 80 having the structure according to the present embodiment, the board terminal 16 can be positioned more accurately and easily by inserting the board terminal 16 through the terminal insertion hole 100. Since the fitting groove 92 and the terminal insertion hole 100 are formed only in the cover member 86, the fitting groove 92 and the terminal insertion hole 100 can be formed with high dimensional accuracy, and the positioning accuracy of the board terminal 16 is increased. Can be secured. Furthermore, the overlapping surface 88 of the main body member 84 can be a single plane, and the shape of the main body member 84 can be simplified.

  As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited by the specific description. For example, as shown in FIG. 10, the board-side end 64 of the board terminal 16 may be positioned without protruding outward in the width direction of the board 14 like a base connector 110 as a different aspect of the present invention. The pedestal connector 110 has substantially the same structure as the pedestal connector 10 as the first embodiment, and the fitting groove 28 of the main body member 18 extends on the side surface 34 and is opposite to the overlapping surface 24. Is opened on the bottom surface 112 of the. Then, the board-side end portion 64 is fitted into the fitting groove 28 opened on the side surface 34, thereby projecting from the bottom surface 112 toward the printed circuit board 12 without projecting from the side surface 34.

  Further, the specific shape of the fitting groove is not limited to that of the above embodiment. For example, in the first embodiment, by forming a terminal insertion hole penetrating the main body member 18 and connecting the end portion on the opposite side of the center protrusion 26 in the fitting groove 28 to the terminal insertion hole, The fitting groove 28 may be opened on the bottom surface of the main body member 18 without opening on the side surface 34 of the main body member 18. In this way, the board-side end 64 of the board terminal 16 can be accurately positioned by being inserted into the terminal insertion hole that penetrates the main body member 18. Furthermore, in each of the above embodiments, by forming the fitting groove on only one of the main body member and the cover member, it was possible to ensure the dimensional accuracy of the fitting groove with higher accuracy. For example, the fitting groove may be partially formed on each of the main body member and the cover member, and the main body member and the cover member may cooperate to form the fitting groove.

  Further, the board terminal is not necessarily limited to a crank shape. For example, by using an L-shaped board terminal, it is possible to form a pedestal connector in which an end connected to the mating connector protrudes to the side of the printed board. Further, the bending angle of the bent portion of the board terminal is not limited to a right angle, and the fitting groove and the overlapping surface are inclined according to the bending angle of the bent portion by being inclined with respect to the extending direction of the board terminal. You may make it.

  In addition, the substrate terminal is not limited to a linear one. For example, it is possible to use a tab-shaped terminal having a flat section with a substantially long rectangular shape, or a combination of a tab-shaped terminal and a linear terminal may be used.

  Furthermore, it is also possible to form leg portions on the cover member so as to be in contact with the printed circuit board. In this way, it is possible to more effectively obtain the supporting force against the pressing force when the counterpart connector is connected.
