Description

  The present invention relates to an electrical connector for connection (hereinafter, referred to as “connector for board”) that is connected to the electrical connector for board (hereinafter referred to as “substrate connector”) that is respectively disposed on two circuit boards. Further, the present invention relates to a connector assembly having the connection connector and the board connector.

  As such a connector assembly, the one disclosed in Patent Document 1 is known. In Patent Document 1, a plug as a connecting connector is fitted to the first receptacle and the second receptacle, which are board connectors respectively disposed on two boards, so as to be covered from above. Connecting a first receptacle and a second receptacle is disclosed.

  In Patent Document 1, a first receptacle and a second receptacle having a rectangular parallelepiped shape of the same shape are respectively disposed at end portions of two horizontally disposed substrates that are in contact with each other, and the lower ends of the terminals of the respective receptacles. A land as a corresponding circuit portion on the substrate is electrically connected by soldering. In the first and second receptacles, a plurality of groove portions penetrating in the vertical direction are formed in the direction in which the end portion of the substrate extends, and a terminal having an upper end formed as a contact portion in each groove portion. Is retained. The plug is made of a substantially inverted U-shaped thin metal plate, and has a plurality of jumper leads that are terminals for connecting the first receptacle and the second receptacle. The jumper lead is made of a thin metal plate and has a substantially inverted U shape having two leg portions and a connecting portion connecting the two leg portions. Each of the two legs functions as a contact portion.

  When the plug is fitted over the first receptacle and the second receptacle from above, one leg of the jumper lead of the plug is in the groove of the first receptacle and the other leg is in the second. Are inserted into the groove portions of the receptacles, and contact the contact portions of the terminals of the first and second receptacles within each groove portion. As a result, the first receptacle and the second receptacle are electrically connected via the plug.

The jumper lead as a terminal of the plug is made of a thin metal plate, and the thickness direction of the jumper is the terminal arrangement direction.

JP2003-1000039

  However, in Patent Document 1, when the first receptacle and the second receptacle are shifted from each other in the terminal arrangement direction, the connecting portion of the jumper lead remains elastically deformed in the same direction in the connector fitting state. The state where the legs of the jumper lead are inserted into the grooves of both receptacles is maintained. That is, in the connector fitting state, the leg portion is in contact with the contact portion of the terminals of both receptacles in the terminal arrangement direction, and constantly receives force from the contact portion of the terminals. As a result, the terminal always receives a reaction force from the leg portion, and the reaction force always acts on the solder connection portion between the lower ends of the terminals of both receptacles and the land on the board. If the state in which the reaction force is applied to the terminal and thus the solder connection portion is maintained for a long time, the solder connection portion is damaged, and the electrical connection state is adversely affected.

  In view of such circumstances, the present invention maintains a good electrical connection state without damaging the solder connection portion between the board connector and the board even when the board board connectors are displaced relative to each other. It is an object of the present invention to provide a connecting connector and an assembly having the connector and a board connector.

<First invention>
The electrical connector for connection according to the present invention is connected to electrical connectors for boards that are respectively disposed on two circuit boards whose plate surfaces extend in parallel to each other and connects the electrical connectors for boards.

  In the electrical connector for connection, the present invention includes a housing and a plurality of connection terminals arranged and supported by the housing, and the connection terminal extends in the axial direction with the connector fitting direction as an axis, and the electrical connector for substrates. A contact portion connected to the terminal of the first and second leg portions formed on the distal end side, and a connecting portion connecting the two leg portions, the housing connecting one leg portion more than the contact portion. A first support member supported on the part side, and a second support member supporting the other leg part on the connection part side with respect to the contact part, and the first support member and the second support member include the connection terminal And the other leg portion of the connection terminal is supported so as to be rotatable around the axis, and is relatively displaceable in the terminal arrangement direction.

  In the connection connector of the present invention configured as described above, one leg portion extending from the connection portion of the connection terminal is supported by the first support member so as to be rotatable around the axis, and the other leg portion is the second support member. Is supported so as to be rotatable around the axis. Thus, since both the leg portions are rotatable, the connecting portion can be inclined toward the terminal arrangement direction without elastic deformation. Therefore, even if the relative positions of the two board electrical connectors are deviated in the terminal arrangement direction, the connecting portion is inclined in the deviating direction without elastically deforming the first support member and the second connector. It is possible to relatively displace the support member. Further, since the connecting portion is not elastically deformed, the force that the leg portion receives in the terminal arrangement direction from the terminals of the board electrical connector is extremely small. Therefore, the reaction force applied from the connecting terminal of the connecting electrical connector to the terminal of the board electrical connector is also extremely small.

  The contact portion of the connection terminal of the connection electrical connector is formed with an annular groove having a cylindrical bottom at the middle in the axial direction of the contact portion, and the annular groove is in contact with the terminal of the board electrical connector. It is preferable to be engaged. In this way, by forming such an annular groove in the contact portion of the connecting terminal, even if the contact portion is not a cylindrical shape other than the annular groove, the electrical connector for a board in the contact portion can be used in the contact portion. Since the annular groove engaging with the terminal has a circular cross section perpendicular to the axial direction, its radius is constant at any position in the circumferential direction.

  Accordingly, the first support member and the second support member are relatively displaced in accordance with the displacement of the board electrical connectors in the terminal arrangement direction before the annular groove and the terminals of the board electrical connector are engaged. Then, when engaging the terminals of the board electrical connector, the connectors are completely fitted with the relative displacement, that is, with the legs rotated, and the annular groove and the board When the terminal of the electrical connector is brought into contact and engaged, the distance between the axis and the contact point (radius of the annular groove) is constant in the circumferential direction, so that the contact state is the rotation angle of the leg, That is, it is constant regardless of the relative angular position of the leg with respect to the terminal of the board electrical connector.

  In addition, after the annular groove of the electrical connector for connection and the terminal of the electrical connector for board are engaged, an inadvertent external force is applied to the electrical connector for board in the terminal arrangement direction. Even if the relative angular position changes due to the relative position of the electrical connectors in the terminal arrangement direction being shifted, the radius of the cross section of the annular groove is constant in the circumferential direction, that is, the distance between the axis and the contact is the circumference. Since the direction is constant, the contact state between the annular groove and the terminal of the board electrical connector is kept constant. Therefore, a stable electrical contact state between the connectors can be ensured. Moreover, since the terminal of the board | substrate electrical connector can be latched with the edge part of the said annular groove in the axial direction of a contact part, the disconnection of connectors is suppressed by this.

  The housing of the electrical connector for connection has a guided portion that is guided by the guide portion while contacting the guide portion formed in the electrical connector for the board in the terminal arrangement direction prior to connection between the terminals when the connector is fitted. It is preferable.

  By adopting such a configuration, when fitting the connectors together, first, before connecting the connecting terminal of the connecting electrical connector and the terminal of the board connector, the guide portions of the two board electrical connectors are connected. Thus, the guided portion of the connecting electrical connector comes into contact. Here, even if the relative positions of the two board electrical connectors are shifted in the terminal arrangement direction, if the connector fitting operation is performed as it is, the guided part of the connecting electrical connector becomes the guide part of the board electrical connector. While being guided in the terminal arrangement direction while being guided in the guide portion, the first support member and the second support member of the connecting electrical connector are relatively aligned in the terminal arrangement direction so as to correspond to the positions of the two board electrical connectors. Displace. At this time, both leg portions of the connecting terminal of the connecting electrical connector rotate around the axis, and the respective leg portions relatively move in the terminal arrangement direction.

  In this way, since the respective leg portions in each connection terminal are relatively displaced, before the terminals are connected, in the terminal arrangement direction, the position of the connection terminal of the connection electrical connector and the position of the terminal of the board connector Match. Therefore, if the connector fitting operation in the connector fitting direction is advanced as it is, the terminals can be connected without difficulty.

  The housing of the connecting electrical connector has a receiving groove for receiving at least a part of the connecting portion of the connecting terminal, and the receiving groove forms a gap with the connecting portion in the terminal arrangement direction. It is preferable. As described above, when a gap is formed between the receiving groove and the connecting portion in the terminal arrangement direction, the inclination of the connecting portion in the terminal arrangement direction is allowed by the gap. Thereby, the relative displacement in the terminal arrangement direction of the first support member and the second support member becomes possible.

<Second invention>
A connector assembly according to the present invention is arranged on the two electrical circuit boards whose plate surfaces extend in parallel with each other and the electrical connector for connection according to the first invention, and is fitted and connected to the electrical connector for connection. Board electrical connector.

  In such a connector assembly, according to the present invention, the electrical connector for connection includes a housing and a plurality of connection terminals arranged and supported by the housing, and the connection terminals are arranged in the axial direction with the connector fitting direction as an axis. The contact portion connected to the terminal of the board electrical connector and having two contact portions formed on the distal end side, and a connecting portion connecting the two leg portions, the housing having one leg portion And a second support member for supporting the other leg portion on the connection portion side with respect to the contact portion, the first support member and the second support member. The member is connected by the connecting terminal, supports one and other leg portions of the connecting terminal so as to be rotatable about the axis, and is relatively displaceable in the terminal arrangement direction. The terminal The contact portion of the connecting terminal of Kuta is characterized in that supported rotatably about the axis.

  Also in this connector assembly, like the first invention, one and the other leg portions of the connecting portion of the connecting terminal are rotatably supported by the first support member and the second support member around the axis. Further, in the connector fitting state, the contact portions of both the leg portions of the connecting electrical connector are supported so as to be rotatable around the axis by the terminals of the board electrical connector. Thus, since both the leg portions are rotatable, the connecting portion can be inclined toward the terminal arrangement direction without elastic deformation. Therefore, in the connector fitting state, even if the relative position in the terminal arrangement direction of the two board electrical connectors is shifted, according to this, the connecting portion is inclined in the direction of shift without elastically deforming, It is possible to relatively displace the first support member and the second support member. Further, since the connecting portion is not elastically deformed, the force that the leg portion receives in the terminal arrangement direction from the terminals of the board electrical connector is extremely small. Therefore, the reaction force applied from the connecting terminal of the connecting electrical connector to the terminal of the board electrical connector is also extremely small.

  The terminals of the board electrical connector have a pair of elastic pieces formed with corresponding contact portions that come into contact with the contact portions of the connection terminals of the connection electrical connector, and the corresponding contact portions are connected to the pair of elastic pieces. It is preferable that the protrusions are formed so as to protrude toward each other and clamp the contact portion of the connecting terminal.

  By configuring the terminals of the board electrical connector in this manner, the contact portions of the connecting terminals are clamped by the corresponding contact portions formed on the elastic pieces of the terminals of the board electrical connector in the connector fitting state. Since the corresponding contact portion is a protrusion, the contact area of the connecting terminal with respect to the contact portion is small. Therefore, even if the relative position in the terminal arrangement direction of the board electrical connectors is shifted as a result of an inadvertent external force applied to the board electrical connector in the connector fitting state, the legs are not rotated. Made easy.

  The contact portion of the connection terminal of the connection electrical connector is formed with an annular groove having a cylindrical bottom in the axial direction intermediate portion of the contact portion, and is sandwiched between the contact portions of the board electrical connector by the annular groove. It is preferable that the pressure is applied. In this way, by forming such an annular groove in the contact portion of the connecting terminal, even if the contact portion is not a cylindrical shape other than the annular groove, the electrical connector for a board in the contact portion can be used in the contact portion. Since the annular groove sandwiched between the corresponding contact portions has a circular cross section perpendicular to the axial direction, its radius is constant at any position in the circumferential direction.

  Therefore, before the annular groove is clamped by the corresponding contact portion, the first support member and the second support member are relatively displaced according to the displacement of the board electrical connectors in the terminal arrangement direction, Thereafter, when the annular groove is clamped by the corresponding contact portion, the connectors are completely fitted in the state where the relative displacement is made, that is, the leg portion is rotated, and the annular groove is fitted to the corresponding contact portion. Since the annular groove has a constant distance between the axis and the contact point (radius of the annular groove) in the circumferential direction, the contact pressure is the rotation angle of the leg portion, that is, the contact with the corresponding contact portion. Regardless of the relative angular position of the legs.

  Further, after the annular groove of the electrical connector for connection is clamped by the corresponding contact portion of the electrical connector for board, an inadvertent external force is applied to the electrical connector for board in the terminal arrangement direction, Even if the relative angular position changes due to a shift in the relative position in the terminal arrangement direction of the electrical connectors for circuit boards, the radius of the cross section of the annular groove is constant in the circumferential direction, that is, the distance between the axis and the contact Is constant in the circumferential direction, the contact pressure between the annular groove and the corresponding contact portion is maintained constant. Therefore, a stable electrical contact state between the connectors can be ensured. Moreover, since the terminal of the board | substrate electrical connector can be latched with the edge part of the said annular groove in the axial direction of a contact part, the disconnection of connectors is suppressed by this.

  Corresponding contact portions of the terminals of the board electrical connector are formed as ridges extending in a direction parallel to the circuit board, and the housing of the board electrical connector is located at a position corresponding to the corresponding contact portion. It is preferable to have a hole for receiving the leg of the connecting terminal, and the hole extends in the same direction as the corresponding contact portion.

  The corresponding contact portion is formed as a ridge extending in a direction parallel to the circuit board, and the hole of the housing has a shape extending in the same direction as the corresponding contact portion. Even when the relative position deviates from the normal position in the direction in which the corresponding contact portion extends in parallel with the circuit board, the contact state between the contact portion of the connecting electrical connector and the corresponding contact portion of the board electrical connector can be secured.

  In the connector for connection according to the present invention, even if the relative position of the two board connectors is deviated from the normal position in the terminal arrangement direction, the one and other legs rotate around the axis in accordance with this, The connecting portion is not elastically deformed but is inclined toward the direction of displacement, and the first support member and the second support member are relatively displaced in the terminal arrangement direction. Since elastic deformation does not occur in the connecting portion of the connecting terminal, the force that the leg of the connecting terminal receives from the terminal of the board connector in the terminal arrangement direction is extremely small, and the board electrical connector from the connection terminal of the connecting electrical connector The reaction force applied to the terminal is extremely small. As a result, since the reaction force is not applied to the solder connection portion between the terminal of the board connector and the corresponding circuit portion of the circuit board, damage to the solder connection portion is avoided during long-term use of the connector assembly. Thus, a good electrical connection state can be maintained.

  Further, in the connector assembly according to the present invention, the terminal of the board electrical connector supports the contact portion of the connection terminal of the connection connector so as to be rotatable about the axis. Even when the relative position between the board connectors is shifted in the terminal arrangement direction due to a prepared external force, the connecting portion is inclined in the terminal arrangement direction without elastically deforming the first support member and the first support member. The two support members can be relatively displaced in the terminal arrangement direction. Therefore, even if the relative positions of the two board connectors are deviated in the terminal arrangement direction, damage to the solder connection portion can be avoided and a good electrical connection state can be maintained.

  In this way, the first support member 31 supports the leg portion 21 on the connecting portion 23 side with respect to the contact portion 21A in the axial direction of the leg portion 21, and the second support member 32 supports the leg portion 22 on the leg portion 22. It is supported on the connecting portion 23 side than the contact portion 22A in the axial direction. Further, the legs 21 and 22 supported by the first support member 31 and the second support member 32 have a slight gap between the inner peripheral surfaces of the support holes 31D-1 and 32D-1. The support holes 31D-1 and 32D-1 are rotatable around the axis of the legs 21 and 22. Thus, when the connection terminal 20 is attached to the first support member 31 and the second support member 32, the first support member 31 and the second support member 32 are connected by the connection terminal 20. In addition, as described above, since the leg portions 21 and 22 are rotatable, the first support member 31 and the second support member 32 are simply connected to the terminal without tilting the connecting terminal 20. Relative displacement in the arrangement direction is possible. During the relative displacement, only the joint portion 33 that joins the first support member 31 and the second support member 32 is elastically deformed in the terminal arrangement direction.

  Next, the first support member 31 and the second support member 32 are arranged so as to cover the insulating plates from above. Here, the protrusions 31F-1 and 32F-1 of the partition walls 31F and 32F penetrate the holes formed in the respective insulating plates from below, so that the respective insulating plates are arranged at fixed positions. By the arrangement of the insulating plate, contact avoidance between the metal plates 41 and 42 and the connecting terminal 20 is ensured. Then, the first metal plate 41 and the second metal plate 42 are respectively attached to the first support member 31 and the second support member 32 from above, and the assembly of the connection terminal 10 is completed.

  In the connecting connector 10 assembled in this way, the first connector portion 11 includes a first support member 31 that supports the leg portions 21 of the connecting terminals 20, a first metal plate 41, and a first insulating plate 51. have. The second connector portion 12 includes a second support member 32 that arrayably supports the leg portions 22 of the connection terminals 20, a first metal plate 42, and a second insulating plate.

  In the present embodiment, in the connecting connector 10 that has been assembled, an insulating plate is disposed between the metal plate 40 and the connecting portions 23 of all the connecting terminals 20, and the metal plate 40 and the connecting terminal 20. However, instead of this, at least one of the plurality of connecting terminals 20 is used as a ground terminal, and the connecting portion of the ground terminal is brought into contact with the metal plate 40 to form the metal plate 40. A shielding function may be provided. For example, a hole is formed in the insulating plate at a position between the ground terminal and the metal plate 40, and at the position corresponding to the hole, the upper edge of the connecting portion of the ground terminal is projected upward, The ground terminal and the metal plate 40 can be brought into contact with each other by forming the lower surface of the metal plate 40 so as to protrude downward. As a result, in the connector fitting state, the metal plate 40 can be grounded to the grounding circuit provided on the circuit boards P1 and P2 via the ground terminal.

  In the present embodiment, the insulating plate is separate from the metal plate 40, but instead of this, an insulating layer may be provided integrally with the metal plate 40. For example, it is possible to form an insulating layer by attaching an insulating material to the inner surface of the metal plate 40, that is, the surface facing the connection terminal when the connection connector assembly is completed before the connection connector 10 is assembled. . Thus, by integrating the connecting terminal and the insulating layer in advance, the step of disposing the insulating plate on the connecting terminal 20 can be omitted when the connecting connector 10 is assembled. Assembling of the connector 10 is facilitated.

  FIG. 4 is a perspective view showing board connectors 60 and 90 disposed on the circuit boards P1 and P2, respectively. In the figure, in the board connectors 60 and 90, only the terminal shown on the rightmost side of the figure is shown, and the other terminals are not shown. In FIG. 4, the rightmost terminal is shown connected to the connecting terminal 20 of the connecting connector 10. FIG. 5 is a perspective view showing the connection terminal 20 of the connection connector 10 and the terminals 70 and 100 of the board connectors 60 and 90. Since the board connector 60 and the board connector 90 have the same configuration, in the present embodiment, the configuration of the board connector 60 will be mainly described. The reference numerals obtained by adding 30 to the reference numerals of the constituent parts are omitted.

  The board connector 60 includes a plurality of terminals 70 (see FIG. 5) and a housing 80 that supports the plurality of terminals 70 at the same interval as the interval between the connection terminals 20 of the connection connector 10. (See FIGS. 6A and 6B). As shown in FIG. 5, the terminal 70 includes a plate-like base portion 71 having a connection direction as a longitudinal direction, and a pair of elastic pieces 72 extending upward from both side edges of the base portion 71 at a central position in the connection direction of the base portion 71. And a pair of fixed portions 73A and 73B extending upward from both side edges of the base portion 71 on both sides of the elastic piece 72 in the connecting direction, and a connecting portion 74 extending in the connecting direction from both ends in the connecting direction of the base portion 71. And have.

  The elastic piece 72 has a pair of arm portions 72A extending upward, and an introduction portion 72B that connects the upper ends of the pair of arm portions 72A and receives the leg portion 21 of the connector 10 from above when the connector is fitted. In addition, since the central portion has a window shape, the thinly formed arm-like portion 72A can be elastically deformed in the terminal arrangement direction. The introduction portions 72B of the pair of elastic pieces 72 are bent so as to protrude toward each other, and the protruded portions contact the contact portions 21A of the connection terminals 20 of the connector 10 for connection. 1 is formed. The corresponding contact portion 72B-1 has a ridge extending in the connecting direction.

  The fixed portions 73A and 73B are press-fitted from below into a fixing hole portion (not shown) for attaching the terminal 70 formed on the lower surface of the housing 80 of the board connector 60. Thus, the terminal 70 is attached to the housing 80. The lower surface of the connecting portion 74 is solder-connected to a corresponding circuit portion (not shown) provided on the circuit board P1 (see FIGS. 1 and 4).

  As shown in FIG. 4, the housing 80 of the board connector 60 has a rectangular parallelepiped shape extending in the terminal arrangement direction. The dimension in the terminal arrangement direction is substantially the same as the dimension in the same direction of the receiving recess 31J of the housing 30 of the connector 10 and the dimension in the connecting direction is smaller than the dimension in the same direction of the receiving recess 31J (see FIG. 9). The housing 80 has a plurality of accommodating portions 81 for accommodating the terminals 70 in the terminal arrangement direction (see FIGS. 6A and 6B).

  Further, on the upper surface of the housing 80, a hole 82 communicating with the accommodating portion 81 is formed at a position corresponding to the corresponding contact portion 72B-1 of each terminal 70 as shown in FIG. 6 (See also (A) and (B)). The hole portion 82 is adapted to receive the contact portion 21 </ b> A of the leg portion 21 of the connecting connector 10. As is often seen in FIG. 4, the hole 82 has an oval shape extending in the same direction as the corresponding contact portion 72B-1 shown in FIG. The dimension of the hole 82 in the connecting direction is substantially the same as or slightly larger than the dimension of the corresponding contact part 72B-1 in the same direction, and is larger than the diameter of the contact part 21A of the connecting terminal 20. Yes.

  At both ends of the housing 80 in the terminal arrangement direction, as shown in FIG. 4, guide portions for guiding guided portions 31K provided in the receiving recesses 31J of the connector 10 shown in FIG. 83 is formed. The guide portion 83 is formed as a rectangular hole that penetrates the housing 80 in the vertical direction. The size of the guide portion 83 is substantially the same as the size of the guided portion 31K in the terminal arrangement direction. It is the same and is larger than the guided portion 31K in the connecting direction (see FIG. 9). A guiding slope 83A is formed on the upper edge of the guide portion 83 to facilitate the guidance of the guided portion 31K when the connector is fitted (see FIGS. 6A and 6B). .

  As shown in FIG. 4, a groove portion is formed at a position corresponding to each terminal 70 in a lower portion of the side surface of the housing 80 extending in the terminal arrangement direction, and a connecting portion 74 of the terminal 70 is formed from the groove portion. Protrudes outside the housing 80.

  Next, how to use the connector assembly 1 according to this embodiment will be described.

  The relative positions of the board connectors 60 and 90 are as shown in FIG. 4 at positions where the relative positions of the board connectors 60 and 90 are not shifted in the connection direction and the terminal arrangement direction, that is, from the normal position to the connection direction and the terminal arrangement. There may be deviation in the direction. For example, when the board connectors 60 and 90 are arranged at positions shifted from the normal positions on the circuit boards P1 and P2, or when the board connectors 60 and 90 are disposed on the circuit boards P1 and P2, the relative positions are shifted. This may occur when the circuit boards P1 and P2 themselves are arranged at positions deviated from the normal position with respect to the member of the device to be attached even if they are arranged at the regular positions on P2.

  According to the connector assembly 1 according to the present embodiment, not only when the board connectors 60 and 90 are in the normal position as shown in FIG. 4, the relative position is somewhat in the connecting direction and the terminal arrangement direction. Even if it is a case where it has shifted | deviated, it can be made to fit by normal fitting operation | movement.

  Hereinafter, in the description of the usage procedure of the connector assembly 1, when the relative positions in the connecting direction and the terminal arrangement direction of the two board connectors 60 and 90 are in the normal position, the relative position is changed from the normal position to the connecting direction. The connector fitting when the relative position slightly deviates from the normal position in the terminal arrangement direction when there is a slight deviation will be described.

  FIG. 6 is a cross-sectional view of the first connector portion 11 and the board connector 60 on a plane perpendicular to the connecting direction. FIG. 6A shows the connector fitting state before the connector fitting. Since the form of fitting of the second connector part 12 and the board connector 90 is the same as the form of fitting of the first connector part 11 and the board connector 60, here, the first connector part 11 and the board The connector fitting with the connector 60 will be mainly described.

<When the board connectors 60 and 90 are in the normal position>
When the board connectors 60 and 90 are in the normal positions and the relative positions are not shifted in the terminal arrangement direction, first, the guided portions 31K and 32K of the connection connector 10 and the guide portions 83 and 113 of the board connectors 60 and 90 are used. Match the position with. 6A shows a state in which the positions of the guided portion 31K of the first connector portion 11 and the guide portion 83 of the board connector 60 are aligned in the terminal arrangement direction (left-right direction in FIG. 6A). ing. Further, when the positions of the guided portion 31K and the guiding portion 83 coincide, the positions of the leg portion 21 of the connecting terminal 20 and the terminal 70 of the board connector 60 are also shown in FIG. 6A. Match.

  In the present embodiment, the first support member 31 of the first connector portion 11 and the second support member 32 of the second connector portion 12 are joined by the joint portion 33. Therefore, when the coupling connector 10 is fitted to the board connectors 60 and 90, the relative position between the first connector portion 11 and the second connector portion 12 is maintained constant by the joining of the joint portion 33. Therefore, it is very easy to position the connectors.

  Next, the fitting operation is performed so that the connecting connector 10 is pushed downward into the board connectors 60 and 90. In the first connector part 11 and the board connector 60, when the first connector part 11 is lowered toward the board connector 60 from the state shown in FIG. The guided portion 31K of the connector portion 11 enters the guide portion 83 of the board connector 60, and as shown in FIG. 6B, the guided portion 31K penetrates the guide portion 83 and the guided portion The leading end of the guide portion 31K reaches the hole P1A of the circuit board P1. In this manner, the normal positional relationship with the board connectors 60 and 90 is maintained by the connecting connector 10.

  On the other hand, the contact portion 21A of the leg portion 21 of the connecting terminal 20 supported by the first connector portion 11 passes through the hole portion 82 of the board connector 60, and then the tip portion of the contact portion 21A, that is, the annular groove 21A-1. The portion on the more distal side enters between the corresponding contact portions 72B-1 while elastically displacing and opening the pair of corresponding contact portions 72B-1 provided on the terminals 70 of the board connector 60. Then, when the tip of the contact portion 21A passes through the position of the corresponding contact portion 72B-1, the corresponding contact portion 72B-1 is released from the elastic displacement, and as shown in FIG. It contacts the annular groove 21A-1.

  FIG. 7 is an enlarged view of the contact portion of the contact portion 21A of the connecting terminal 20 and the corresponding contact portion 72B-1 of the terminal 70 in FIG. As is often seen in FIG. 7, the pair of corresponding contact portions 72B-1 sandwich the contact portion 21A in the diametrical direction with an annular groove 21A-1. Thus, when the corresponding contact portion 72B-1 is in pressure contact with the annular groove 21A-1, the leg portion 21 of the connecting terminal 20 and the terminal 70 are electrically connected, and the first connector portion 11 and The mating with the board connector 60 is completed.

  In the present embodiment, as described above, the annular groove 21A-1 is formed in the contact portion 21A, and the annular groove 21A is formed by the pair of corresponding contact portions 72B-1 formed as ridges in the terminal 70. -1 is pinched. Therefore, even when the upward force in FIGS. 6A and 6B is inadvertently applied to the connector 10 in the connector fitting state, the connecting terminal 20 and the terminal in the connecting direction are used. 70, the corresponding contact portion 72B-1 is locked with the edge of the annular groove 21A-1 in the axial direction of the leg portion, that is, in the connector fitting direction. It is possible to suppress the disconnection between the connectors.

  The fitting between the second connector portion 12 and the board connector 90 is performed in the same manner as the fitting between the first connector section 11 and the board connector 60 described above. Thus, by completing the fitting between the first connector portion 11 and the board connector 60 and the fitting between the second connector portion 12 and the board connector 90, the board connector 60 and the board connector 90 Are connected by a connecting connector 10 and are electrically connected via the connecting connector 10.

  FIG. 8 is a plan view showing the connector assembly 1 in a state where the connector fitting is completed. In the drawing, the metal plate 40 and the insulating plate are not shown in order to show the state of the connecting terminal 20. Since the board connectors 60 and 90 have the same relative position in the terminal arrangement direction, the connecting connector 10 fitted to the board connectors 60 and 90 is between the first connector portion 11 and the second connector portion 12. The relative position in the terminal arrangement direction at is not shifted. Therefore, as shown in FIG. 8, the connecting portion 23 of the connecting terminal 20 and the joint portion 33 of the housing 30 are positioned without being inclined in the connecting direction, that is, the left-right direction in FIG. 8.

<When the relative positions of the board connectors 60 and 90 are shifted in the connecting direction>
Next, connector fitting when the relative position in the connecting direction of the board connectors 60 and 90 is slightly deviated from the normal position will be described.

  First, the positions of the guided portions 31K and 32K of the connection connector 10 and the guide portions 83 and 113 of the board connectors 60 and 90 are matched. However, in the present embodiment, the relative position in the connecting direction of the first connector portion 11 and the second connector portion 12 is not shifted in the connecting connector 10, whereas the two board connectors 60, 90 are The relative position in the connecting direction is slightly shifted. Accordingly, when the positions of the guided portion provided in one connector portion of the first connector portion 11 and the second connector portion 12 and the guide portion corresponding to the guided portion are matched, the covered portion provided in the other is provided. The relative position between the guide portion and the guide portion corresponding to the guided portion will deviate from the normal position in the connecting direction. At this time, the contact portion 21A of the first connector portion 11 has not yet reached the hole portion 82 of the housing 80 of the board connector 60.

  In the present embodiment, a case will be described in which the positions of the guided portion 32K of the second connector portion 12 serving as the one connector portion and the guide portion 113 of the board connector 90 corresponding to the guided portion 32K are matched. In this case, the relative position between the guided portion 31K of the first connector portion 11 as the other connector portion and the guide portion 83 of the board connector 60 corresponding to the guided portion 31K is shifted from the normal position in the connecting direction. In the present embodiment, the guided portion 31K and the guiding portion 83 have a range in which the guided inclined surface 31K-1 of the guided portion 31K and the guiding inclined surface 83A of the guiding portion 83 overlap in the connecting direction. To some extent.

  Next, a fitting operation is performed so that the connecting connector 10 is pushed into the board connectors 60 and 90 from above. When the connecting connector 10 is pushed in from above, the guided portion 31K of the first connector portion 11 is guided to the inclined surface 31K-1 of the guided portion 31K prior to the connection between the connecting terminal 20 and the terminal 70. Is guided to the guide portion 83 while abutting the guide slope 83A of the guide portion 83 of the board connector 60 in the connecting direction.

  Thus, in the process in which the guided portion 31K is guided in the connecting direction, the first connector portion 11 is connected to the guided portion 31K of the first connector portion 11 and the board as shown in FIG. The connector 60 is brought to a position where the guide portion 83 coincides with the guide portion 83. As a result, both the relative position between the first connector part 11 and the board connector 60 and the relative position between the second connector part 12 and the board connector 90 are the same in the terminal arrangement direction and the connecting direction.

  The form of fitting between the first connector part 11 and the board connector part 60 brought to such a relative position is the case where the relative position of the board connectors 60 and 90 is in the normal position as described above. Since it is the same as the form of fitting of the first connector portion 11 and the board connector 60 brought to the position shown in FIG. Further, the second connector portion 12 and the board connector 90 can be fitted in the same manner as in the case where the relative positions of the board connectors 60 and 90 are in the normal positions.

  Such correction of the relative position will be further described in detail with reference to FIG. FIG. 9 is a bottom view of the first connector portion 11 and the board connector 60 shown in FIG. 6B, and a part thereof shows a cross section taken along the line IX-IX. In FIG. 9, the circuit board P1 is not shown. As described above, the housing 80 of the board connector 60 has a dimension in the connecting direction (vertical direction in FIG. 9) smaller than the dimension in the same direction of the receiving recess 31J.

  In the present embodiment, as shown in FIG. 9, when the housing 80 is in the center of the receiving recess 31J in the connecting direction in the receiving recess 31J, as described above, in the connecting direction. A gap of a dimension a is formed in the connection direction between both outer wall surfaces 80A of the housing 80 and the inner wall surface of the receiving recess 31J.

  Further, the inner dimension of the board connector 60 in the connecting direction of the guide part 83 is larger than the dimension of the first connector part 11 in the same direction of the guided part 31K. In the present embodiment, as described above, as shown in FIG. 9, the gap of the dimension b in the connecting direction is provided between the outer wall surfaces of the guided portion 31 </ b> K and the inner wall surface of the guiding portion 83. Is formed. The dimension b is the same as or larger than the dimension a. In the present embodiment, the second connector portion 12 and the board connector 90 are in the same positional relationship as the first connector section 11 and the board connector 60 in the connector fitting state.

  As described above, the hole 82 of the housing 80 of the board connector 60 has an inner dimension in the connecting direction larger than the diameter of the contact portion 21 </ b> A of the connecting terminal 20. In the present embodiment, as already described, as shown in FIG. 9, when the contact portion 21A is at the center position in the connecting direction of the hole 82, the contact portion 21A and the hole 82 are provided. A gap of dimension c is formed in the connecting direction between the edge portion of the first and second edges. The dimension c is the same as or larger than the dimension a. In the present embodiment, the second connector portion 12 and the board connector 90 are in the same positional relationship as the first connector section 11 and the board connector 60 in the connector fitting state.

  In the present embodiment, since a gap in the coupling direction is formed between the outer wall surface 80A of the housing 80 and the inner wall surface of the receiving recess 31J, the relative position between the board connector 60 and the board connector 90 is Even if the position is slightly deviated from the normal position, that is, the position shown in FIG. 9, the housing 80 is accommodated in the receiving recess 31 </ b> J and is in contact with the connecting connector 10 in the connector fitting state. The contact state between the portion 21A and the corresponding contact portion 72B-1 of the board connector 60 can be ensured.

  In the present embodiment, since a gap of a dimension a is formed between the wall surface 80A of the housing 80 and the inner surface of the receiving recess 31J, the board connector 60 is in a normal position (shown in FIG. 9) in the connecting direction. From the normal position to the inner side of the housing (downward in FIG. 9) in the connecting direction. Deviation is allowed. Similarly to the board connector 60, the board connector 90 is allowed to have a maximum deviation of the dimension a from the normal position to the outside and the inside of the housing in the connecting direction. Therefore, the relative position between the board connector 60 and the board connector 90 is a direction approaching each other from the normal position in the connecting direction, that is, the dimension 2a at the maximum inward of the housing, and a direction away from each other, that is, the dimension at the maximum outward of the housing Even if it is shifted by 2a, the connecting connector 10 can be fitted to the board connectors 60, 90 without difficulty.

  In the present embodiment, as described above, the dimension b between both outer wall surfaces of the guided portion 31K and the inner wall surface of the guide portion 83, the edge portion of the hole portion 82 of the housing 80, and the annular groove 21A of the contact portion 21A. The dimension c of the gap with -1 is equal to or larger than the dimension a between the outer wall surfaces 80A of the housing 80 and the inner surface of the receiving recess 31J. Therefore, when the board connector 60 is displaced from the normal position by the dimension a in the connecting direction, the annular groove 21A comes into contact with the edge of the hole 82, or the outer wall surface of the guided portion 31K is the guide portion 83. By abutting against the inner wall surface, the tolerance of the deviation of the dimension a is not hindered.

<When the relative positions of the board connectors 60 and 90 are shifted in the terminal arrangement direction>
Next, connector fitting when the relative positions in the terminal arrangement direction of the board connectors 60 and 90 are slightly shifted will be described.

  First, the positions of the guided portions 31K and 32K of the connection connector 10 and the guide portions 83 and 113 of the board connectors 60 and 90 are matched. However, in the present embodiment, in the connector 10 for connection, the relative positions in the terminal arrangement direction between the first connector portion 11 and the second connector portion 12 are not shifted, whereas the two board connectors 60 and 90 are not. The relative position in the terminal arrangement direction is slightly shifted. Therefore, when the position of the guided part provided in one of the first connector part 11 and the second connector part 12 and the position of the guide part corresponding to the guided part are matched, the guided part provided in the other The relative position of the guided portion corresponding to the guided portion is shifted in the terminal arrangement direction. At this time, the contact portion 21A of the first connector portion 11 has not yet reached the hole portion 82 of the housing 80 of the board connector 60.

  In the present embodiment, a case will be described in which the positions of the guided portion 32K of the second connector portion 12 and the guide portion 113 of the board connector 90 are matched. In this case, the relative position between the guided portion 31K of the first connector portion 11 and the guide portion 83 of the board connector 60 is shifted from the normal position in the terminal arrangement direction. In the present embodiment, the guided portion 31K and the guiding portion 83 are such that the guided slope 31K-1 of the guided portion 31K and the guiding slope 83A of the guiding portion 83 overlap in the terminal arrangement direction. It is assumed that the range is shifted to some extent.

  Next, a fitting operation is performed so that the connecting connector 10 is pushed into the board connectors 60 and 90 from above. When the connecting connector 10 is pushed in from above, the guided portion 31K of the first connector portion 11 is guided to the inclined surface 31K-1 of the guided portion 31K prior to the connection between the connecting terminal 20 and the terminal 70. Is guided to the guide portion 83 while abutting against the guide slope 83A of the guide portion 83 of the board connector 60 in the terminal arrangement direction.

  In this way, the guided portion 31K is guided in the terminal arrangement direction, so that the first connector portion 11 is connected to the guided portion 31K of the first connector portion 11 and the board as shown in FIG. The guide portion 83 of the connector 60 is brought into a position that coincides with the terminal arrangement direction. As a result, both the relative position between the first connector part 11 and the board connector 60 and the relative position between the second connector part 12 and the board connector 90 in the terminal arrangement direction match.

  The form of fitting between the first connector part 11 and the board connector part 60 brought to such a relative position is the case where the relative position of the board connectors 60 and 90 is in the normal position as described above. Since it is the same as the form of fitting of the first connector portion 11 and the board connector 60 brought to the position shown in FIG. Further, the second connector portion 12 and the board connector 90 can be fitted in the same manner as in the case where the relative positions of the board connectors 60 and 90 are in the normal positions.

  Such correction of the relative position will be further described in detail with reference to FIGS. 10 and 11. FIG. 10 is a plan view showing the connector assembly 1 in a state where the connector fitting is completed. In the drawing, the metal plate 40 and the insulating plate are not shown in order to show the state of the connecting terminal 20. The connecting terminal 20 extending in the connecting direction before the connector fitting is elastically bent due to the relative position in the terminal arrangement direction of the first connector portion 11 and the second connector portion 12 being shifted after the connector fitting. Without being brought about in a posture inclined from the connecting direction to the terminal arrangement direction as shown in FIG. Further, as the relative positions of the first connector portion 11 and the second connector portion 12 are shifted, only the joint portion 33 is elastically deformed into a posture inclined in the terminal arrangement direction from the connection direction as shown in FIG.

  Hereinafter, the change in the posture of the connecting terminal 20 when the connector is fitted will be further described with reference to FIG. In the present embodiment, as described above, the connecting terminal 20 has the leg portion 21 rotated around the axis of the leg portion 21 with respect to the support hole 31D-1 by the first support member 31 of the first connector portion 11. The leg portion 22 is supported by the second support member 32 of the second connector portion 12 so as to be rotatable about the axis of the leg portion 22 with respect to the support hole 32D-1. Therefore, when the guided portion 31K of the first connector portion 11 is guided in the terminal arrangement direction by the guide portion 83 of the board connector 60, the leg portions 21 and 22 rotate around their respective axes. With the rotation, the connecting portion 23 of the connecting terminal 20 is tilted in the direction in which the first connector portion 11 is guided in the left-right direction when viewed from above, and assumes the posture shown in FIG. At this time, since the leg portions 21 and 22 rotate around their axes, the inclined connecting portion 23 does not bend.

  FIG. 11 is an enlarged view showing a part of the connection terminal 20 accommodated in the accommodation groove 31G of the first connector portion 11 shown in FIG. As described above, the size of the accommodation groove 31G in the terminal arrangement direction is larger than the size of the end portion of the connection portion 23 of the connection terminal 20 in the same direction. That is, as shown in FIG. 11, a gap of dimension d is formed in the terminal arrangement direction between the accommodation groove 31G and the end of the connecting portion 23 accommodated in the accommodation groove 31G. In addition, a gap similar to the accommodation groove 31G is formed in the accommodation groove 32G of the second connector portion 12 as well.

  The connecting portion 23 is allowed to be inclined with the rotation of the legs 21 and 22 around the axis by the gaps in the receiving grooves 31G and 32G. Specifically, as shown in FIG. 11, a position extending in the connecting direction (position before connector fitting) illustrated by a two-dot chain line, and a position tilted with respect to the connecting direction illustrated by a solid line (Position after connector fitting), i.e., within the range of dimension d. As a result, the first connector portion 11 can be moved with respect to the second connector portion 12 so as to be displaced in the terminal arrangement direction. In the present embodiment, the deviation between the board connector 60 and the board connector 90 in the terminal arrangement direction is allowed to increase as the dimension d increases. In addition, the displacement is allowed to be greater as the distance between the first connector portion 11 and the second connector portion 12 in the connecting direction is larger and the connecting portion 23 becomes longer accordingly.

  Note that it is not essential to provide the housing 30 with the partition portions 31F and 32F that form the housing grooves 31G and 32G. This is because when the partition walls 31F and 32F are not provided, the connecting portion 23 of the connecting terminal 20 can be inclined without being restricted by the dimension 2d.

  When the connecting portion 23 is inclined, the distance between the leg portion 21 and the leg portion 22 in the connecting direction changes. The distance in the connecting direction between the leg portion 21 and the leg portion 22 when the connecting portion 23 is inclined from the normal position, that is, the position extending in the connecting direction, is the connection before the connecting portion 23 is inclined, ie, when the connecting portion 23 is in the normal position. It is slightly shorter than the distance between the leg 21 and the leg 22 in the direction. In other words, it can be said that the leg portion 21 and the leg portion 22 are moving in the connecting direction while the connecting portion 23 is inclined.

  In this embodiment, as is often seen in FIG. 4, the holes 82 and 112 of the housings 80 and 110 of the board connectors 60 and 90 are formed in an oval shape extending in the connecting direction. , 112 between the contact portions 21A, 22A of the leg portions 21, 22 and the edge portions of the hole portions 82, 112, as shown in FIG. Has been. Movement in the connecting direction between the leg 21 and the leg 22 when the connecting portion 23 is inclined is allowed by the gap. In this way, the movement of the legs 21 and 22 in the connecting direction is allowed, so that the connecting portion 23 and thus the inclination of the connecting terminal 20 is allowed.

  Further, in this embodiment, as shown in FIG. 9, the corresponding contact portions 72B-1 and 102B-1 of the board connectors 60 and 90 extend in substantially the same dimension as the holes 82 and 112 in the connecting direction. Therefore, even if the leg portions 21 and 22 move in the connecting direction due to the inclination of the connecting portion 23, the contact portions 21A and 22A of the leg portions 21 and 22 and the corresponding contact portions 72B-1 and 102B-1 The contact state can be secured at all times.

  In the present embodiment, the connecting terminal 20 has the leg portion 21 supported by the first support member 31 of the first connector portion 11 and the leg portion 22 supported by the second support member 32 of the second support member 32. Yes. Therefore, even if the relative positions of the board connector 60 and the board connector 90 are shifted in the terminal arrangement direction, the first connector portion 11 and the second connector portion 12 can be relatively displaced in accordance with this.

  Further, the leg portions 21 and 22 are supported by the first support member 31 and the second support member 32 and the terminals 70 and 100 of the board connectors 60 and 90 so as to be rotatable around the axis line. When the portion 11 and the second connector portion 12 are relatively displaced in the terminal arrangement direction, the leg portions 21 and 22 rotate about the axis with respect to the support holes 31D-1 and 32D-1, and the connection terminal 20 is connected. The portion 23 is inclined in the terminal arrangement direction without elastic deformation. Therefore, the force in the terminal arrangement direction that the leg portions 21 and 22 receive from the terminals 70 and 100 of the board connectors 60 and 90 due to the inclination of the connecting portion 23 is extremely small. Note that only the joint portion 33 is elastically deformed in the terminal arrangement direction as described above.

  Therefore, a very small reaction force from the leg portions 21 and 22 due to the inclination of the connecting portion 23 and a reaction force due to the elastic deformation of the joint portion 33 act on the terminals 70 and 100. The joint portion 33 is provided only at two locations in the terminal arrangement direction of the first support member 31 and the second support member 32, and the reaction force due to the elastic deformation of the joint portion 33 is extremely small. Accordingly, the reaction force from the leg portions 21 and 22 and the joint portion 33 applied to the solder connection portion between the terminals 70 and 100 of the board connectors 60 and 90 and the corresponding circuit portion on the circuit board is extremely small. Even when the solid 1 is used for a long period of time, damage to the solder connection portion is avoided and a good electrical connection state can be maintained.

  Further, the joint portion 33 is provided for positioning the connecting connector 10 when fitting and connecting to the board connectors 60 and 90, and plays a role especially after the connector fitting is completed. Therefore, there is no problem even if the joint portion 33 is cut after completion of connector fitting. By cutting the joint portion 33, the reaction force due to the elastic deformation of the joint portion 33 is small, but even the reaction force does not occur. As a result, the terminals 70 and 100 of the board connectors 60 and 90 and the circuit The reaction force does not act on the solder connection portion with the substrate-like corresponding circuit portion. This improves the effect of avoiding damage to the solder connection part and the effect of maintaining a good electrical connection state.

  In the present embodiment, the connecting portion 33 is provided in the connecting connector 10 for positioning the connectors at the time of connector fitting. However, the connecting portion 33 is not essential and is not provided in the connecting connector 10. May be.

  In the present embodiment, the annular grooves 21A-1 and 22A-1 formed in the contact portions 21A and 22A of the leg portions 21 and 22 of the connecting connector 10 use the annular grooves 21A-1 and 22A-1 for the board connector. Since the corresponding contact portions 72B-1 and 102B-1 are in contact with the corresponding contact portions 72B-1 and 102B-1, the corresponding contact portions 72B-1 and 102B-1 are axial lines of the leg portions 21 and 22 in the connector fitting state. In the direction, that is, the connector fitting direction, it is engaged with the edge of the annular grooves 21A-1 and 22A-1, thereby preventing the connector from coming off.

  Further, in this embodiment, as shown in FIG. 5, the corresponding contact portions 72B-1 and 102B-1 that sandwich the annular grooves 21A-1 and 22A-1 are formed as protrusions extending in the connecting direction. Therefore, the contact area between the annular grooves 21A-1 and 22A-1 and the corresponding contact portions 72B-1 and 102B-1 can be reduced. As a result, even if the relative position of the board electrical connectors 60 and 90 in the terminal arrangement direction is shifted as a result of an inadvertent external force applied to the board electrical connectors 60 and 90 in the connector fitting state. The legs 21 and 22 can be easily rotated.

  In the present embodiment, the positions of the second connector portion 12 and the board connector 90 in the connecting direction and the terminal arrangement direction are aligned, and the connector is fitted in a state where the positions of the first connector section 11 and the board connector 60 are shifted. However, instead of this, the first connector part 11 and the board connector 60 are aligned, and the second connector part 12 and the board connector 90 are displaced from each other. It goes without saying that you may go.

  In the present embodiment, the case where the relative position of the board connector 60 and the board connector 90 is deviated from the normal position in the connection direction or the terminal arrangement direction has been described. However, in the present embodiment, the relative position is the connection direction and the terminal. Needless to say, it is effective even when the position is shifted from the normal position in both directions of the arrangement direction.

  At the relative positions of the board connectors 60 and 90, the board connectors 60 and 90 are displaced in the connecting direction, in the terminal arrangement direction, and in both directions, the inclination in the plane parallel to the circuit board surface is caused. Misalignment can occur. In the connecting connector 10 according to the present embodiment, the first connector portion 11 and the second connector portion 12 allow relative displacement in the connecting direction and the terminal arrangement direction, as described above, to allow these deviations. Relative displacement, combined relative displacement in both directions, is possible with compound relative displacement having an inclination in a plane parallel to the circuit board surface.

  Therefore, in this embodiment, it is possible to displace the 1st connector part 11 and the 2nd connector part 12 according to all the above-mentioned shift | offset | difference in the board | substrate connectors 60 and 90, and it can fit connectors without difficulty. Can do.

  Further, at the time of the composite relative displacement in the connection connector 10, the connection portion 23 of the connection terminal 20 is inclined without being elastically deformed similarly to the relative displacement in the terminal arrangement direction. Since the connecting portion 23 is inclined, a reaction force caused by elastic deformation of the connecting portion 23 is not applied to the solder connecting portion between the terminals 70 and 100 of the board connectors 60 and 90 and the corresponding circuit portion. Damage to the solder connection portion is avoided, and a good electrical connection state can be maintained.

  In this embodiment, the hole portions of both board connectors have an oval shape extending in the connecting direction, as can be seen in FIG. 4, but instead, one board connector is used. The hole portion of the other board connector may be formed as a circle having substantially the same diameter as the outer peripheral circle of the leg portion of the connection terminal.

  FIG. 12 is a diagram showing an example in which the hole of one board connector is formed in an oval shape and the hole of the other board connector is formed as a circle. The one board connector is the board connector 60 of the present embodiment. Even in this configuration, the holes 21 and 22 and the connecting portion 23 are allowed to tilt while the hole 82 of the board connector 60 and the hole 112 ′ of the board connector 90 ′ are allowed to tilt, and the above-mentioned hole 23 is inclined. The portion 82 allows displacement of the leg portion 21 in the connecting direction. In other words, relative displacement combined with both the terminal arrangement direction and the connection direction of the first connector portion 11 with respect to the second connector portion 12 is possible. Needless to say, the hole 82 of the board connector 60 may be formed in a circular shape, and the hole 112 ′ of the board connector 90 may be formed in a long hole shape.

  In the present embodiment, the connecting connector is connected to the board connectors respectively disposed on the two circuit boards whose plate surfaces extend in parallel with each other on the same horizontal plane, and connects both board connectors. However, the position of the circuit board and the position of the board connector that can be handled by the present invention are not limited to this. For example, the circuit board and the board connector may be positioned so as to be displaced in the vertical direction, or the surfaces of the two circuit boards on which the board connector is attached may be reversed. In short, it is only necessary that the relative positions of the connectors for both boards viewed in the vertical direction are as described above.

  For example, as shown in FIG. 13 which is a side view seen from a direction parallel to the surface of the circuit board, the board connector is the same in two circuit boards whose plate surfaces extend parallel to each other on different horizontal planes. You may arrange | position on the board surface of the side. In the figure, illustration of members other than the connection terminal 120 of the connection connector is omitted. As shown in the figure, the board connector 90 is arranged on the circuit board P2 at a position higher in the connector fitting direction than the board connector 60 arranged on the circuit board P1, The connecting portion 123 of the connecting terminal 120 connected to the two board connectors is bent in a crank shape.

  Further, as shown in FIG. 14 which is a side view similar to FIG. 13, the board connector is provided on the board surfaces opposite to each other in the two circuit boards extending in parallel to each other on different horizontal planes. It may be arranged. In the figure, illustration of members other than the terminal 220 of the connector for connection is omitted. As shown in the figure, the board connector 60 arranged on the circuit board P1 is arranged on the circuit board P2 at a position higher than the board connector 90 in the connector fitting direction. The board connector 60 is disposed on the lower surface of the circuit board P1, and the board connector 90 is disposed on the upper surface of the circuit board P2. In the connection terminal 223 of the connection connector connected to both the board connectors, the leg 221 connected to the board connector 60 is formed to extend upward from one end of the connection part 223. The leg part 222 connected to 90 is formed to extend downward from the other end part of the connecting part 223.

  In the present embodiment, the leg portion of the connecting terminal has a cylindrical shape, but the shape of the leg portion is not limited to this. For example, as shown in FIG. 15A, the leg portion has a substantially quadrangular prism shape, and extends in the connector fitting direction at the center position in the connecting direction of the plane perpendicular to the terminal arrangement direction. The cross section perpendicular to the shape may have a shape in which the protruding strip portion 321A having a convexly curved shape is formed. By forming the leg portion in such a shape, even when the relative position of the board connectors is shifted in the terminal arrangement direction due to an inadvertent external force in the connector fitting state, the leg portion 321 is used. Can be easily rotated.

  Further, as shown in FIG. 15B, the leg portion 421 of the connecting terminal is formed in a quadrangular prism shape, and is pressed between the corresponding contact portions of the board connector by the quadrangular prism-shaped ridge line 421A. It may be. Thus, by making the leg part 421 into a quadrangular prism shape and making contact with the corresponding contact part at the ridge line 421A, the contact area between the leg part 421 and the corresponding contact part becomes small, so the leg part 421 and the corresponding contact part The contact pressure with can be increased. Further, in the connector fitting state, the leg portion 421 can be easily rotated even when the relative position between the board connectors is shifted in the terminal arrangement direction due to an inadvertent external force.

  Further, as shown in FIG. 15C, the leg portion of the connecting portion has a substantially quadrangular prism shape, and the cross-section perpendicular to the terminal arrangement direction is curved in a substantially kamaboko shape is perpendicular to the terminal arrangement direction. You may make it the shape formed in the surface. By forming the leg portion in such a shape, even when the relative position of the board connectors is shifted in the terminal arrangement direction due to an inadvertent external force in the connector fitting state, the leg portion 521 is used. Can be easily rotated.

  Further, as shown in FIG. 16A, the leg portion of the connecting portion may be formed in a rectangular parallelepiped shape extending in the connecting direction. Since the connecting terminal 620 having such a shape can be manufactured only by punching a metal plate, the connecting terminal can be easily manufactured as compared with the present embodiment requiring punching and pressing. it can.

  Moreover, when making a leg part into the said rectangular parallelepiped shape, it is preferable that the corresponding contact part of a board | substrate connector is formed as a projection part which protrudes in the direction which mutually approaches from the opposing surface of a pair of elastic piece. FIG. 16B is a cross-sectional view in a plane perpendicular to the connection direction in the contact state between the connection terminal of the connection connector and the terminal of the board connector, and shows the position of the protrusion in the connection direction. A cross section is shown. As shown in the figure, the terminal 670 of the board connector makes point contact with the leg portion 621 of the connecting terminal 620 at the corresponding contact portion 672B formed as the protruding portion. Accordingly, the contact area between the leg portion 621 and the corresponding contact portion 672B is reduced, so that the contact pressure between the leg portion 621 and the corresponding contact portion 672B can be increased. Further, in the connector fitting state, the leg portion 621 can be easily rotated even when the relative positions of the board connectors are shifted in the terminal arrangement direction due to an inadvertent external force.

  In FIGS. 15A to 15C and FIGS. 16A and 16B, only one leg is illustrated, but the other leg is also formed in the same shape as the one leg.

  In this embodiment, the connecting terminal of the connecting connector is manufactured by punching a metal plate in a U-shape and then pressing the portion extending downward to form two cylindrical legs. However, instead of this, the connecting terminal is formed by bending both ends of a rod-shaped metal member having a circular cross section perpendicular to the axis in the same direction. It is good also as a U-shaped member. FIG. 17 is a diagram illustrating an example thereof, in which the members other than the connection terminal 720 of the connection connector and the circuit board are not shown. Since the connecting terminal 720 can be manufactured simply by bending a rod-shaped metal member having a circular cross section perpendicular to the axis, the connecting terminal 720 can be manufactured more easily than the hook-shaped connecting terminal. Further, since the connecting terminal 720 has a circular outer peripheral surface, the correspondence between the leg portions 721 and 722 and the board connector can be obtained regardless of the rotation angle of the leg portions 721 and 722 as in the present embodiment. A constant contact pressure can be maintained in contact with the contact portion.
