     SUMMARY OF THE INVENTION 
     Problems to be Solved 
     In the case of applying the above connection structure for connecting the first and second connectors via the adapter to a multipole connector device, there is concern over the following problem. Since the adapters are freely rockable with respect to the first connector, each adapter is possibly inclined in a direction different from the other adapters in a state where the first and second connectors are not connected yet. Thus, when an attempt is made to connect a plurality of the first connectors and a plurality of second connectors, it is difficult to connect a plurality of the adapters to the second connectors at once. 
     A connector of the present disclosure was completed on the basis of the above situation and the present disclosure aims to provide a connector device excellent in the reliability of a connecting operation. 
     Means to Solve the Problem 
     The present disclosure is directed to a connector device with a housing to be mounted on a circuit board, a plurality of mounting terminals to be mounted into the housing and connected to the circuit board, a plurality of movable terminals individually rockable with the plurality of mounting terminals as fulcrums, the movable terminals being individually connected to a plurality of mating terminals, and a coupling member formed such that the plurality of movable terminals are passed therethrough. 
     Effect of the Invention 
     According to the present disclosure, the reliability of a connecting operation is excellent.

     DETAILED DESCRIPTION TO EXECUTE THE INVENTION 
     Description of Embodiments of Present Disclosure 
     First, embodiments of the present disclosure are listed and described. 
     (1) The connector device of the present disclosure is provided with a housing to be mounted on a circuit board, a plurality of mounting terminals to be mounted into the housing and connected to the circuit board, a plurality of movable terminals individually rockable with the plurality of mounting terminals as fulcrums, the movable terminals being individually connected to a plurality of mating terminals, and a coupling member formed such that the plurality of movable terminals are passed therethrough. According to the configuration of the present disclosure, since the plurality of movable terminals are integrally rocked by the coupling member, the plurality of movable terminals are kept in a fixed positional relationship. In this way, the plurality of movable terminals are reliably connected to the mating terminals, wherefore the connector device of the present disclosure is excellent in connection function. 
     (2) Preferably, the plurality of movable terminals are formed with holding portions for holding the plurality of movable terminals in a state passed through the coupling member. According to this configuration, since the plurality of movable terminals are held in the state passed through the coupling member, the housing needs not be provided with a structure for preventing the separation of the coupling member from the plurality of movable terminals. Therefore, the housing can be reduced in size and, consequently, the entire device can be reduced in size. 
     (3) Preferably, the coupling member is formed with resilient holding pieces to be resiliently locked to the holding portions. According to this configuration, when the coupling member and the movable terminals are relatively inclined as the plurality of movable terminals rock, the resilient holding pieces are flexibly resiliently deformed by being pushed by the holding portions. Thus, prying is hardly caused between the coupling member and the movable terminals. In this way, the movable terminals smoothly rock. 
     (4) Preferably, the coupling member is made of an electrically conductive material, and the coupling member is formed with resilient contact pieces configured to resiliently contact movable-side outer conductors of the movable terminals. According to this configuration, since a plurality of the movable-side outer conductors are made conductive via the coupling member, a potential difference is not generated among the plurality of movable-side outer conductors. Therefore, the connector device of the present disclosure is excellent in grounding function. 
     (5) Preferably, the coupling member is plate-like, and the coupling member is formed with a rib-like projecting reinforcing portion. According to this configuration, since the coupling member can be prevented from being deformed to strain by the reinforcing portion, the orientations and postures of the plurality of movable terminals during rocking movements can be aligned. 
     (6) Preferably, in (5), the reinforcing portion includes a first reinforcing rib bent to project from an outer peripheral edge of the coupling member and a second reinforcing rib arranged along the outer peripheral edge in a region of the coupling member separated from the outer peripheral edge. A part of the coupling member along the outer peripheral edge is reinforced by the first and second reinforcing ribs. Out of a part connected to the outer peripheral edge of the coupling member, a region where the first reinforcing rib bent to project from the outer peripheral edge cannot be formed can be reinforced by the second reinforcing rib. 
     (7) Preferably, in (6), the first and second reinforcing ribs are partially arranged in the same region in a length direction of the outer peripheral edge. According to this configuration, the entire region of the part connected to the outer peripheral edge of the coupling member can be reliably reinforced by either one of the first and second reinforcing ribs. 
     Details of Embodiment of Present Disclosure 
     Embodiment 
     One specific embodiment of a connector device of the present disclosure is described below with reference to  FIGS.  1  to  8   . Note that the present invention is not limited to these illustrations and is intended to be represented by claims and include all changes in the scope of claims and in the meaning and scope of equivalents. In this embodiment, an oblique right lower side in  FIGS.  1 ,  2  and  6    and a right side in  FIGS.  4  and  8    are defined as a front side concerning a front-rear direction. Upper and lower sides shown in  FIGS.  1  to  7    are directly defined as upper and lower sides concerning a vertical direction. An oblique left lower side in  FIGS.  1  and  2    is defined as a left side and left and right sides shown in  FIG.  3    are directly defined as left and right sides concerning a lateral direction. 
     The connector device of this embodiment includes, as shown in  FIGS.  1  and  2   , a first connector  10 , a second connector  30 , movable terminals  40  and a coupling member  60 . As shown in  FIG.  3   , the first connector  10  is mounted on a first circuit board Pa, and the second connector  30  is mounted on a second circuit board Pb. The first circuit board Pa is, for example, provided in an ECU (not shown) mounted in a roof of an automotive vehicle, and horizontally arranged with a mounting surface facing up, i.e. facing toward the side of an antenna. The second circuit board Pb is, for example, provided in the antenna (not shown) to be mounted in the roof (not shown) of the automotive vehicle. The second circuit board Pb is horizontally arranged with a mounting surface facing down, i.e. facing toward a vehicle interior side. The first and second circuit boards Pa, Pb are arranged in such a positional relationship that the mounting surfaces of the both are facing in parallel to each other. 
     If the first and second circuit boards Pa, Pb are brought closer, the both circuit boards Pa, Pb are connected via the first connector  10 , the second connector  30  and the movable terminals  40 . Since the first and second circuit boards Pa, Pb are connected without via a wiring harness, high-speed communication is possible between the first and second circuit boards Pa, Pb. Since assembly tolerances of the roof and the antenna are relatively large in an antenna mounted part in the roof of the automotive vehicle, position shifts possibly occur between the first and second circuit boards Pa, Pb in a horizontal direction intersecting a connecting direction of the both connectors  10 ,  30 . The connector device of this embodiment is configured such that the both connectors  10 ,  30  are connected while the position shifts of the both circuit boards Pa, Pb are accommodated by rocking movements of the movable terminals  40 . 
     First Connector  10   
     As shown in  FIGS.  3  and  4   , the first connector  10  includes a first housing  11  and a plurality of mounting terminals  13 . With the first connector  10  mounted on the first circuit board Pa, the lower surface of the first housing  11  is fixed to the first circuit board Pa and lower end parts of the plurality of mounting terminals  13  are connected to a printed circuit (not shown) of the first circuit board Pa. 
     The first housing  11  is a single component having a rectangular parallelepiped shape and made of synthetic resin. The first housing  11  is formed with as many first terminal accommodation chambers  12  as the mounting terminals  13 . The first terminal accommodation chambers  12  vertically penetrate through the first housing  11 . The plurality of first terminal accommodation chambers  12  are divided into two left and right rows, and three chambers are arranged to be aligned in a row in the front-rear direction in each row. The plurality of mounting terminals  13  are individually accommodated in the plurality of first terminal accommodation chambers  12 . 
     The mounting terminal  13  includes a mounting-side inner conductor  14  made of metal, a mounting-side dielectric  17  made of synthetic resin and a mounting-side outer conductor  18  made of metal. The mounting-side inner conductor  14  is a single component having a tubular shape with an axis oriented in the vertical direction orthogonal to the first circuit board Pa and including a mounting portion  15  and a mounting-side connecting portion  16 . The mounting-side dielectric  17  has a hollow cylindrical shape with an axis oriented in the vertical direction. The mounting portion  15  of the mounting-side inner conductor  14  is accommodated in a center hole of the mounting-side dielectric  17 . The mounting-side connecting portion  16  projects upward from the upper end surface of the mounting-side dielectric  17 . 
     The mounting-side outer conductor  18  is a single component including an angular tube portion  19  having a regular octagonal shape and eight resilient arms  20 . The eight resilient arms  20  extend upward from the angular tube portion  19  and are arranged side by side at equal angular intervals in a circumferential direction. A retaining portion  21  bent to project toward an inner peripheral side is formed on an upper end part (projecting end part) of each resilient arm  20 . The eight resilient arms  20  surround the mounting-side connecting portion  16  of the mounting-side inner conductor  14  above the mounting-side dielectric  17 . 
     By individually accommodating the plurality of mounting terminals  13  into the plurality of first terminal accommodation chambers  12 , the first connector  10  is configured. The first connector  10  is mounted on the first circuit board Pa. With the first connector  10  mounted on the first circuit board Pa, the mounting portions  15  of the mounting-side inner conductors  14  are conductively welded to the mounting surface of the first circuit board Pa and lower end parts of the mounting-side outer conductors  18  are conductively welded to a ground circuit (not shown) on the mounting surface of the first circuit board Pa. 
     Second Connector  30   
     As shown in  FIGS.  3  and  4   , the second connector  30  includes a second housing  31  and as many mating terminals  36  as the mounting terminals  13 . With the second connector  30  mounted on the second circuit board Pb, the upper surface of the second housing  31  is fixed to the mounting surface of the second circuit board Pb and upper end parts of a plurality of the mating terminals  36  are connected to a printed circuit (not shown) of the second circuit board Pb. The second housing  31  is a single component made of synthetic resin and including a terminal holding portion  32  having a rectangular parallelepiped shape and a rectangular guiding portion  34 . 
     The terminal holding portion  32  is formed with a plurality of (six in this embodiment) second terminal accommodation chambers  33  vertically penetrating through the terminal holding portion  32 . The second terminal accommodation chambers  33  are obtained by vertically inverting the first terminal accommodation chambers  12 . The plurality of mating terminals  36  are individually accommodated in the plurality of second terminal accommodation chambers  33 . The mating terminal  36  is the same component as the mounting terminal  13  and mounted in the second terminal accommodation chamber  33  in an orientation vertically inverted from that of the mounting terminal  13 . Accordingly, components and parts of the mating terminal  36 , which are the same as those of the mounting terminal  13 , are not described and are denoted by the same reference signs as the components and parts constituting the mounting terminal  13 . 
     The guiding portion  34  projects obliquely downward in a skirt-like manner from the outer peripheral edge of the lower end of the terminal holding portion  32 . The guiding portion  34  is inclined to become wider toward the bottom (toward the first connector  10 ) with respect to the connecting direction of the both connectors  10 ,  30 . An internal space of the guiding portion  34  communicates with the plurality of second terminal accommodation chambers  33  and is open downward of the second housing  31 . The second connector  30  is mounted on the mounting surface of the second circuit board Pb in a manner similar to a mounting mode of the first connector  10  on the first circuit board Pa. 
     Movable Terminal  40   
     As shown in  FIGS.  2  to  5   , the movable terminal  40  has an elongated shape with an axis oriented in the vertical direction (facing direction of the first and second circuit boards Pa, Pb) as a whole. In this embodiment, a lower end part of the movable terminal  40 , i.e. an end part on the side of the first circuit board Pa and on the side of the first connector  10 , is defined as a base end part  40 P. An upper end part of the movable terminal  40 , i.e. an end part on the side of the second circuit board Pb and on the side of the second connector  30 , is defined as a tip part  40 T. The movable terminal  40  is a member configured by assembling a movable-side inner conductor  41  made of metal, a movable-side dielectric  44  made of synthetic resin and a movable-side outer conductor  48  made of metal. 
     The movable-side inner conductor  41  has a tubular shape elongated in an axial direction of the movable terminal  40 . The movable-side inner conductor  41  is a single component including a hollow cylindrical body portion  42  and a pair of movable-side connecting portions  43  formed on both upper and lower end parts of the body portion  42 . The movable-side dielectric  44  has a hollow cylindrical shape coaxial with the movable-side inner conductor  41 . The movable-side inner conductor  41  is coaxially accommodated in an insertion hole  45  of the movable-side dielectric  44 . Circular accommodation recesses  46  are formed in both end parts in the axial direction of the movable-side dielectric  44  by coaxially recessing both upper and lower end surfaces of the movable-side dielectric  44 . The accommodation recesses  46  communicate with the insertion hole  45 . The movable-side connecting portions  43  are accommodated in the accommodation recesses  46 . 
     The movable-side outer conductor  48  has a hollow cylindrical shape as a whole. The movable-side outer conductor  48  coaxially surrounds the movable-side dielectric  44 . A lower end part of the movable-side dielectric  44  projects further downward than the lower end of the movable-side outer conductor  48 , and an upper end part of the movable-side dielectric  44  projects further upward than the upper end of the movable-side outer conductor  48 . The movable terminal  40  is configured by assembling the movable-side inner conductor  41 , the movable-side dielectric  44  and the movable-side outer conductor  48 . 
     As shown in  FIG.  5   , a positioning protrusion  49 , a projection-like first holding portion  51 , a projection-like second holding portion  52  and four retaining projections  53  are formed on the outer peripheral surface of the movable-side outer conductor  48 . The positioning protrusion  49  is in the form of a rib extending in the vertical direction in parallel to the axis of the movable-side outer conductor  48 , and projects radially outward from the outer peripheral surface of the movable-side outer conductor  48 . The first holding portion  51  projects further radially outward in a stepped manner from a projecting end surface in the lower end part of the positioning protrusion  49 . 
     The second holding portion  52  projects obliquely downward from a position in a formation range of the positioning protrusion  49  in the vertical direction on the outer peripheral surface of the movable-side outer conductor  48 . The second holding portion  52  is arranged at a position above the first holding portion  51  and different from the first holding portion  51  in a circumferential direction. The four retaining projections  53  are arranged at equal angular intervals in the circumferential direction. The four retaining projections  53  are arranged at positions below the first and second holding portions  51 ,  52  (closer to the base end part  40 P of the movable terminal  40 ) and project obliquely upward from the outer peripheral surface of the movable-side outer conductor  48 . 
     The movable terminal  40  is mounted in the first connector  10  by inserting the base end part  40 P of the movable terminal  40  into the first terminal accommodation chamber  12  from above the first housing  11 . In a mounting process, the mounting-side connecting portion  16  of the mounting-side inner conductor  14  is accommodated into the accommodation recess  46  and resiliently contacts the movable-side connecting portion  43  of the movable-side inner conductor  41 . 
     In the process of mounting the movable terminal  40  into the first connector  10 , the retaining projections  53  interfere with the retaining portions  21  to resiliently deform the resilient arms  20  radially outward. Thus, friction resistance is generated between the resilient arms  20  and the movable-side outer conductor  48 . However, since the number of the retaining projections  53  is four, i.e. half the number of the resilient arms  20 , resistance due to the interference of the retaining projections  53  and the retaining portions  21  is suppressed to be small as compared to the case where eight retaining projections  53  interfere with the eight resilient arms  20 . By the contact of the outer peripheral surface of the movable-side outer conductor  48  with the retaining portions  21 , all the movable-side outer conductors  48  and the mounting-side outer conductor  18  are conductively connected. 
     Since the retaining portions  21  project toward the inner peripheral side, the movable terminal  40  is restricted from being separated upward from the mounting terminal  13  and is held in a rockable state by locking the retaining portions  21  and the retaining projections  53 . In the axial direction of the movable terminal  40 , the contact positions of the retaining portions  21  and the movable-side outer conductor  48  and the contact position of the mounting-side connecting portion  16  and the movable-side connecting portion  43  are at the same height. A rocking fulcrum of the movable terminal  40  is a contact part of the movable-side connecting portion  43  with the mounting-side connecting portion  16 . 
     The lower end part of the movable-side dielectric  44  projects further downward than the lower end edge of the movable-side outer conductor  48 . Accordingly, when the movable terminal  40  rocks, there is no possibility that the movable-side outer conductor  48  contacts the upper end surface of the mounting-side dielectric  17  and the movable-side outer conductor  48  made of metal scratches the mounting-side dielectric  17  made of synthetic resin. 
     The movable terminal  40  mounted in the mounting terminal  13  projects upward from the first housing  11 . The upper end part (tip part  40 T) of the movable terminal  40  is connected to the mating terminal  36  of the second connector  30 . Since one movable terminal  40  is supported in a state in contact with only one mounting terminal  13 , the plurality of movable terminals  40  can individually rock in directions different from the other movable terminals  40 . The connector device of this embodiment includes the coupling member  60  as a means for integrally rocking the plurality of movable terminals  40 . 
     Coupling Member  60   
     The coupling member  60  is formed by stamping an electrically conductive plate material such as a metal plate material into a predetermined shape by press-working. As shown in  FIGS.  6  and  7   , the coupling member  60  is a single component including a base plate portion  61  in the form of a flat plate, a pair of bilaterally symmetrical slope portions  62  in the form of flat plates and a pair of bilaterally symmetrical vertical wall portions  63  in the form of flat plates. In a plan view of the coupling member  60 , the coupling member  60  has a rectangular shape. In a front view of the coupling member  60 , the coupling member  60  has an isosceles trapezoidal shape. 
     In the plan view, the base plate portion  61  has a rectangular shape. The pair of slope portions  62  extend obliquely to lower outer sides from both left and right side edge parts of the base plate portion  61 . The pair of vertical wall portions  63  project downward perpendicularly to the base plate portion  61  from the lower end edges of the slope portions  62 . The base plate portion  61 , the slope portions  62  and the vertical wall portions  63  have the same dimension in the front-rear direction. 
     The coupling member  60  is formed with six holding holes  64  penetrating through the base plate portion  61  and arranged to correspond to the first terminal accommodation chambers  12 . In the plan view, the holding portion  64  has a circular opening. An inner diameter of the holding hole  64  is slightly larger than an outer diameter of the movable-side outer conductor  48 . As shown in  FIGS.  6  to  8   , three abutting portions  65  arranged at equal angular intervals in a circumferential direction and one positioning recess  66  are formed on an opening edge part of each holding hole  64 . Out of the three abutting portions  65 , one abutting portion  65  is arranged at a position closest to the holding hole  64  adjacent in the lateral direction. Out of the three abutting portions  65 , two abutting portions  65  are arranged at an interval in parallel to a boundary line in the front-rear direction between the base plate portion  61  and the slope portion  62 . The positioning recess  66  is arranged at the front end of the holding hole  64 . 
     Each abutting portion  65  is formed by bending upward a part projecting radially inward from the opening edge part of the holding hole  64 . A fracture surface during press-working is exposed on the inner peripheral surface of the opening edge part of the holding hole  64 , but surfaces of the abutting portions  65  facing an opening region of the holding hole  64  are non-fracture surfaces, which were not fractured during press-working. The positioning recess  66  is formed by partially recessing the opening edge part of the holding hole  64 . 
     As shown in  FIG.  8   , the coupling member  60  is formed with six slit groups  68  individually corresponding to the six holding holes  64 . Each slit group  68  is composed of three first to third slits  69 A,  69 B and  69 C communicating with the opening edge of the corresponding holding hole  64 . The three slits  69 A,  69 B and  69 C are parallel to each other and extend in the lateral direction. In particular, the three slits  69 A,  69 B and  69 C pass through the base plate portion  61  and the slope portion  62  and reach a central part of the vertical wall portion  63  in a height direction from a region between the two front and rear abutting portions  65  on the opening edge of the holding hole  64 . 
     A part of the coupling member  60  between the first and second slits  69 A,  69 B functions as a resiliently deformable resilient contact piece  70 . One resilient contact piece  70  is provided to correspond to one holding hole  64 . The resilient contact piece  70  has a bent shape in a front view and is cantilevered from the vertical wall portion  63  toward the holding hole  64 . In a plan view, the resilient contact piece  70  extends toward a center of the holding hole  64 . As shown in  FIGS.  3 ,  6  and  7   , a contact point portion  71  arcuately bent downward is formed on an extending end part of the resilient contact piece  70 . A surface of the contact point portion  71  facing the opening region of the holding hole  64  is a non-fracture surface, which was not fractured during the press-working of the coupling member  60 , similarly to the abutting portions  65 . 
     A part of the coupling member  60  between the second and third slits  69 B,  69 C functions as a resiliently deformable resilient holding piece  72 . An end part of the third slit  69 C communicating with the holding hole  64  is bent to be parallel to a radial direction of the holding hole  64 . One resilient holding piece  72  is provided to correspond to one holding hole  64 . The resilient holding piece  72  has a bent shape in a front view and is cantilevered from the vertical wall portion  63  toward the holding hole  64 , similarly to the resilient contact piece  70 . In a plan view, the resilient holding piece  72  extends toward a position eccentric from the center of the holding hole  64 . An extending end part of the resilient holding piece  72  is arranged to be adjacent to the contact point portion  71  in the circumferential direction and facing the opening region of the holding hole  64 . 
     As shown in  FIGS.  6  to  8   , the coupling member  60  includes four first reinforcing ribs  74  and two second reinforcing ribs  78  to enhance the rigidity of the coupling member  60 . The outer peripheral edge of the coupling member  60  is composed of a front end edge, a rear end edge and both left and right side edges. A strip-like region along the front end edge of the coupling member  60  is defined as a front edge part  60 F. A strip-like region along the rear end edge of the coupling member  60  is defined as a rear edge part  60 R. The first reinforcing ribs  74  are integrally formed to the front edge part  60 F and the rear edge part  60 R. In particular, the first reinforcing rib  74  is composed of a base plate rib  75 , a slope rib  76  and a vertical wall rib  77 . The base plate ribs  75  project downward perpendicularly to the base plate portion  61  from regions of the front and rear end edges of the base plate portion  61  except laterally central parts. The slope ribs  76  project obliquely downward perpendicularly to the slope portions  62  from the entire regions of the front and rear end edges of the slope portions  62 . The vertical wall ribs  77  project perpendicularly to the vertical wall ribs  77  toward the vertical wall portions  63  on opposite sides from the entire regions of the front and rear end edges of the vertical wall portions  63 . The base plate portion  61 , the slope rib  76  and the vertical wall rib  77  are connected into one while having a bent shape in a front view. 
     The second reinforcing ribs  78  are in the form of ribs projecting upward from a laterally central part of the upper surface of the base plate portion  61 . The second reinforcing ribs  78  are arranged in the front edge part  60 F, which is a part behind the front end edge of the base plate portion  61 , and the rear edge part  60 R, which is a part in front of the rear end edge of the base plate portion  61 . The second reinforcing ribs  78  linearly extend in the lateral direction in parallel to the front and rear end edges. Formation ranges of the second reinforcing ribs  78  and those of the first reinforcing ribs  74  overlap in the lateral direction along the front and rear edge parts  60 F,  60 R of the coupling member  60 . In particular, end parts of the first reinforcing ribs  74  in the base plate portion  61 , i.e. end parts of the base plate rib  75 , and both left and right end parts of the second reinforcing rib  78  are arranged to overlap in the front view. 
     In a forming step of the coupling member  60 , a plurality of coupling members  60  connected to strip-like carriers (not shown) are separated. Since the coupling member  60  of this embodiment is linked to the carriers in laterally central parts of the front and rear end edges of the base plate portion  61 , the first reinforcing ribs  74  cannot be formed in the parts of the base plate portion  61  linked to the carriers. However, regions of the base plate portion  61  where the first reinforcing ribs  74  cannot be formed are reinforced by the second reinforcing ribs  78 . 
     After the movable terminals  40  are mounted into the first connector  10 , the coupling member  60  is mounted on the movable terminals  40 . In mounting the coupling member  60 , each holding hole  64  is fit to the movable terminal  40  from above. When the fitting of the holding holes  64  and the movable terminals  40  is started, the contact point portions  71  of the resilient contact pieces  70  contact the outer peripheral surfaces of the movable-side outer conductors  48 . In the process of mounting the coupling member  60  on the movable terminals  40 , the resilient contact pieces  70  are resiliently deformed and the contact point portions  71  slide in contact with the outer peripheral surfaces of the movable-side outer conductors  48 . 
     If the opening edge part of the holding hole  64  butts against an upper end part of the positioning protrusion  49  in the process of fitting the holding hole  64  to the movable terminal  40 , the movable terminal  40  is rotated about the axis of the movable terminal  40  and the upper end part of the positioning protrusion  49  is fit into the positioning recess  66 . By the fitting of the positioning recess  66  and the positioning protrusion  49 , the movable terminal  40  is aligned with the holding hole  64  in the circumferential direction, whereby the six movable terminals  40  are positioned with respect to the coupling member  60 . 
     If the coupling member  60  is further lowered after the movable terminals  40  are positioned, the extending end parts of the resilient holding pieces  72  interfere with the second holding portions  52 . Thus, the resilient holding pieces  72  are resiliently displaced obliquely upward, radially away from the outer peripheral surfaces of the movable-side outer conductors  48 . The resilient holding pieces  72  resiliently return after passing through the second holding portions  52  by being resiliently displaced. The extending end parts of the resiliently returned resilient holding pieces  72  are positioned to be lockable to the second holding portions  52  from below. At the same time as the resilient holding pieces  72  resiliently return or immediately after the resilient holding pieces  72  resiliently return, the opening edge parts of the holding holes  64  come into contact with the first holding portions  51  from above. 
     In the above way, the mounting of the coupling member  60  on the movable terminals  40  is completed, a relative displacement of each movable terminal  40  with respect to the coupling member  60  is restricted and the six movable terminals  40  are coupled via the coupling member  60 . Since the coupling member  60  restricts mutual relative displacements of the six movable terminals  40 , the six movable terminals  40  rock in the same direction and by the same angle at once integrally with the coupling member  60  when an external force in a rocking direction acts on one of the movable terminals  40 . 
     With the coupling member  60  and the movable terminals  40  assembled, the coupling member  60  is restricted from being separated upward from the movable terminals  40  by the locking of the resilient holding pieces  72  and the second holding portions  52 . By the locking of the opening edge parts of the holding holes  64  and the first holding portions  51 , the coupling member  60  is held at such a height as to be lifted upward from the first housing  11 , i.e. in a state not interfering with the first housing  11 . Since the contact point portions  71  of the resilient contact pieces  70  are resiliently in contact with the outer peripheral surfaces of the movable-side outer conductors  48 , six movable-side outer conductors  48  are held at the same potential via the coupling member  60 . 
     Functions and Effects of Embodiment 
     If the first and second circuit boards Pa, Pb are relatively displaced at the time of connecting the first and second connectors  10 ,  30 , the tip part  40 T of any one of the movable terminals  40  comes into contact with the inner surface of the guiding portion  34 . If the connection of the connectors  10 ,  30  proceeds from this state, the tip part  40 T of the movable terminal  40  slides in contact with the inclined inner surface of the guiding portion  34 , whereby the tip parts  40 T of all the movable terminals  40  are integrally guided to connection positions to the mating terminals  36  while changing rocking angles at once. After passing through the guiding portion  34 , the tip parts  40 T of the movable terminals  40  are connected to the mating terminals  36  and the first and second connectors  10 ,  30  are properly connected. When the both connectors  10 ,  30  are properly connected, the first and second circuit boards Pa, Pb are connected via the mounting terminals  13  and the mating terminals  36 . 
     The connector device of this embodiment includes the first housing  11  to be mounted on the first circuit board Pa, the plurality of mounting terminals  13 , the plurality of movable terminals  40  and the coupling member  60 . The plurality of mounting terminals  13  are mounted in the first housing  11  and mounted and connected to the first circuit board Pa. The plurality of movable terminals  40  are individually rockable with the plurality of mounting terminals  13  as fulcrums. The plurality of movable terminals  40  are individually connected to the plurality of mating terminals  36 . The coupling member  60  is formed such that the plurality of movable terminals  40  are passed therethrough to be individually and integrally rockable. 
     According to this configuration, since the plurality of movable terminals  40  are integrally rocked by the coupling member  60 , the tip parts  40 T of the plurality of movable terminals  40  are held in a fixed positional relationship and reliably connected to the plurality of mating terminals  36 . Thus, the connector device of this embodiment is excellent in connection function of the movable terminals  40  and the mating terminals  36 . 
     The plurality of movable terminals  40  are formed with the first holding portions  51  and the second holding portions  52  for holding the plurality of movable terminals  40  in a state passed through the coupling member  60 . According to this configuration, since the plurality of movable terminals  40  are held in the state passed there the coupling member  60 , the first housing  11  needs not be provided with a structure for preventing the separation of the coupling member  60  from the plurality of movable terminals  40 . Since the first housing  11  can be reduced in size in this way, the entire connector device can be reduced in size. 
     The coupling member  60  is formed with the resilient holding pieces  72  to be resiliently locked to the second holding portions  52 . When the coupling member  60  and the movable terminals  40  are relatively inclined as the plurality of movable terminals  40  rock, the resilient holding pieces  72  are flexibly resiliently deformed by being pushed by the second holding portions  52 . Thus, prying is hardly caused between the coupling member  60  and the movable terminals  40 . In this way, the movable terminals  40  smoothly rock. 
     The coupling member  60  is made of an electrically conductive material. The coupling member  60  is formed with the resilient contact pieces  70  configured to resiliently contact the movable-side outer conductors  48  of the movable terminals  40 . According to this configuration, since the plurality of movable-side outer conductors  48  are made conductive via the coupling member  60 , a potential difference is not generated between the plurality of movable-side outer conductors  48 . Therefore, the connector device of this embodiment is excellent in grounding function. 
     Since the coupling member  60  is plate-like, there is a concern that the coupling member  60  is deformed to strain when the movable terminals  40  rock. However, since the coupling member  60  of this embodiment is integrally formed with the first reinforcing ribs  74  and the second reinforcing ribs  78  as rib-like reinforcing portions, the coupling member  60  can be prevented from being deformed to strain. In this way, the orientations and postures of the plurality of movable terminals  40  during rocking movements can be aligned. 
     The reinforcing portions for enhancing the rigidity of the coupling member  60  include the first reinforcing ribs  74  and the second reinforcing ribs  78 . The first reinforcing ribs  74  are bent to project from the front end edge of the front edge parts  60 F and the rear end edge of the rear edge part  60 R, out of the outer peripheral edge of the coupling member  60 . The second reinforcing ribs  78  are arranged in the front and rear edge parts  60 F,  60 R. The second reinforcing ribs  78  are separated from the front and rear end edges of the coupling member  60  and extend along the front and rear end edges. Parts of the coupling member  60  along the front end edge and along the outer peripheral edge are reinforced by the first and second reinforcing ribs  74 ,  78 . Although the first reinforcing ribs  74  are not formed in the laterally central parts of the front and rear end edges of the coupling member  60 , the second reinforcing ribs  78  are arranged in the regions of the front and rear edge parts  60 F,  60 R where the first reinforcing ribs  74  are not formed. The region of the front edge part  60 F of the coupling member  60  where the first reinforcing ribs  74  bent to project from the front end edge of the front edge part  60 F cannot be formed can be reinforced by the second reinforcing rib  78  formed in the front edge part  60 F. The region of the rear edge part  60 R of the coupling member  60  where the first reinforcing ribs  74  bent to project from the rear end edge of the rear edge part  60 R cannot be formed can be reinforced by the second reinforcing rib  78  formed in the rear edge part  60 R. 
     The end parts of the first reinforcing ribs  74  in the base plate portion  61  and the both left and right end parts of the second reinforcing ribs  78  are partially arranged in the same regions in length directions of the front and rear edge parts  60 F,  60 R of the coupling member  60 . According to this configuration, the entire region of the front edge part  60 F of the coupling member  60  and the entire region of the rear edge part  60 R of the coupling member  60  can be reliably reinforced by either the first reinforcing ribs  74  or the second reinforcing ribs  78  or both the first reinforcing ribs  74  and the second reinforcing ribs  78 .
