     OBJECTS AND SUMMARY OF THE INVENTION 
     The substrate connector in Reference 1 does not possess means for receiving external force (reaction force) that acts from the circuit substrate to a conductive terminal. Upon attaching the substrate connector onto the circuit substrate, if the external force (reaction force) acts from the circuit substrate to a substrate-side connecting part of the conductive terminal, the conductive terminal runs and the substrate-side connecting part is not be pressed into a normal position of the circuit substrate in some cases. 
     In view of the above, an object of the present invention is to provide an electrical connector whose substrate-side connecting part of the conductive terminal dose not run even if the external force (reaction force) acts from the circuit substrate to the conductive terminal upon attaching the substrate connector including an alignment member onto the circuit substrate. 
     A first aspect of the present invention provides an electrical connector, comprising: a conductive terminal including: a connector-side connecting part; a substrate-side connecting part; and an L-shaped bent part therebetween; a housing including: a terminal-holding hole holding the conductive terminal between the connector-side connecting part and the bent part; and an opening capable of exposing the substrate-side connecting part, the opening being used for connecting a circuit substrate; an alignment member attached toward the substrate-side connecting part of the conductive terminal so as to close the opening, the alignment member being engaged with the housing in a state where the substrate-side connecting part projects from a through hole for inserting the conductive terminal therein, wherein an engaging unit preventing the substrate-side connecting part of the conductive terminal from moving to the bent part, is provided between the conductive terminal and the through hole. 
     In the electrical connector with this structure, the substrate-side connecting part of the conductive terminal held by the terminal-holding hole of the housing, projects from the through hole of the alignment member attached so as to close the opening of the housing. And, there is, between the conductive terminal and the through hole, the engaging unit preventing the substrate-side connecting part of the conductive terminal from moving to the bent part. 
     Accordingly, the substrate-side connecting part of the conductive terminal never runs even if the external force (reaction force) acts from the circuit substrate to the conductive terminal upon attaching the substrate connector onto the circuit substrate. 
     A second aspect of the present invention provides, in addition to the first aspect, the electrical connector wherein the engaging unit includes an uneven engaging mechanism that engages with the conductive terminal when the alignment member attached with the opening slides in a direction that crosses the substrate-side connecting part of the conductive terminal. 
     With this structure, comparatively easy work of making the alignment member slide in the determined direction enables to surely engage the alignment member with the substrate-side connecting part of the conductive terminal. 
     A third aspect of the present invention provides, in addition to the second aspect, the electrical connector wherein the uneven engaging mechanism includes: a projecting shoulder part provided with the conductive terminal; and a recessed holding part provided in the through hole of the alignment member so as to fit the projecting shoulder part thereinto. 
     With this structure, the projecting shoulder part fits into the recessed holding part to produce a stable engagement state. And, this is also effective in preventing the substrate-side connecting part of the conductive terminal from running to the bent part. 
     A fourth aspect of the present invention provides, in addition to the third aspect, the electrical connector wherein a guide surface guiding the projecting shoulder part toward the recessed holding part, is provided between an inner peripheral surface of the through hole and the recessed holding part when the alignment member slides in the direction that crosses the substrate-side connecting part. 
     A fifth aspect of the present invention provides, in addition to the first aspect, the electrical connector wherein the substrate-side connecting part of the conductive terminal includes a press-fit mechanism. 
     A sixth aspect of the present invention provides, in addition to the first aspect, the electrical connector further comprising: a lock mechanism preventing the alignment member attached with the opening of the housing from being detached therefrom. 
     Effect of Invention 
     According to the present invention, the electrical connector whose substrate-side connecting part of the conductive terminal dose not run even if the external force (reaction force) acts from the circuit substrate to the conductive terminal upon attaching the substrate connector including an alignment member onto the circuit substrate, can be provided.

However, the conductive terminals  10  and  10   x  have basically the same form and the same function as those of the conductive terminal  10  shown in  FIG. 3 . Accordingly, explanation with respect to the other conductive terminals  10  is omitted. In  FIG. 2 , it should be noted that the terminal holder  17  is not provided in the conductive terminals  10   x  with the shortest length and the shortest length but one. 
     As shown in  FIG. 2 ,  FIG. 4 , and  FIG. 5 , a plurality of openings  32  for fitting a mating connector (not shown) therein, are divided by partitions  33  and are provided on a front surface of the housing  30 . And, a screen  34  passing through the housing  30 , is provided behind the openings  32 . Outer side walls  35  and  35  projecting from the screen  34  to the back face side, are provided at both sides of the housing  30 . 
     A plurality of inner side walls  36  and  36  projecting from the screen  34  to the back face side, are provided in an area between the outer side walls  35  and  35  opposing to each other. The inner side walls  36  and  36  are formed so as to have the same interval as those of the partitions  33 . 
     In the housing  30 , openings  30   a  near lower edges of the outer side walls  35  and  35 , are arranged between the outer side walls  35  and  35  opposing to each other. The openings  30   a  correspond to openings being used for connecting a circuit substrate. The openings  30   a  are opened so as to expose the substrate-side connecting parts  13  of the conductive terminals  10  and  10   x  to the outside. 
     The plurality of terminal-holding holes  31  are vertically and horizontally opened through the screen  34  according to a predetermined interval. In a direction from the back face to the front face of the screen  34 , the connector-side connecting parts  12  of the conductive terminals  10  and  10   x  (shown in  FIG. 2  and  FIG. 3 ) are inserted into the terminal-holding holes  31 , and the engaging portions  14  engage with inner surfaces of the terminal-holding holes  31 . And then, the conductive terminals  10  are held by the housing  30 .

And, the lock parts  52  and  53  engage with the lock parts  38  and  39 . 
     As shown in  FIG. 2 , Figs. from  6  to  13 , the alignment member  50  is a plate-like member attached to the openings  30   a  of the housing  30  so as to close the same. A plurality of through holes  55  for inserting the substrate-side connecting parts  13  of the conductive terminals  10  and  10   x  therein, are opened through the alignment member  50  in a thickness direction (See, arrow Y.) thereof. The arrangement of the plurality of through holes  55  is set up so as to have the same phase as that of the arrangement of the plurality of conductive terminals  10  and  10   x  attached to the terminal-holding holes  31  of the housing  30 . 
     Recessed portions  54  are provided at front edge portions of the alignment member  50 . A plurality of projections  34   a  are provided with lower edge portions of the screen  34  of the housing  30 . The projections  34   a  can fit into the recessed portions  54 . The plurality of projections  34   a  are provided at lower portions of a border between the inner side walls  36  and  36  and the screen  34 . The plurality of projections  34   a  have the same interval as that of the inner side walls  36  and  36 . A bridge part  56  is provided with back edge portions of the alignment member  50 . The bridge part  56  can fit into recessed parts  36   a  provided at lower edge portions of the inner side walls  36  of the housing  30 . 
     As shown in  FIG. 6 ,  FIG. 7 , and  FIG. 10 , an upper surface of the alignment member  50  is in a staircase shape that becomes higher from the front edge portion to the back edge portion thereof. Each step is set up to have a height corresponding to vertical positions of the terminal holders  17  of the plurality of conductive terminals  10  held by the housing  30 . 
     As shown in  FIG. 11 , each of the plurality of through holes  55  opened through the alignment member  50 , includes the followings. That is, a mortar-like guide section  55   a  is opened toward the upper surface of the alignment member  50 . A penetrating part  55   b  penetrates from a lower edge portion of the guide section  55   a  toward the lower surface of the alignment member  50 . And, a recessed holding part  55   c  is formed so as to be recessed toward the back of the alignment member  50  within the penetrating part  55   b . Between an inner peripheral surface of the penetrating part  55   b  and the recessed holding part  55   c , a suspended part  55   g  having a guide surface  55   d  is provided. 
     As shown in  FIG. 8 ,  FIG. 9 , and  FIG. 12 , a pair of shoulder part inserting grooves  55   e  are formed in the through holes  55  of the alignment member  50 . The shoulder part inserting grooves  55   e  radially expand from the inner peripheral surface of the penetrating part  55   b , and oppose to each other in 180 degrees. There is provided a moving path  55   f  spreading from the penetrating part  55   b  toward the recessed holding part  55   c.    
     Next, referring to Figs. from  14  to  18 , processes of assembling the electrical connector  100  shown in  FIG. 1  will now be explained. 
     As shown in  FIG. 14 ( a ) , inserting the connector-side connecting parts  12  of the plurality of conductive terminals  10  and  10   x  of into the plurality of terminal-holding holes  31  opened through the screen  34  of the housing  30  from the back surface to the front surface of the screen  34 , respectively, causes to press-insert the engaging portions  14  of the conductive terminals  10  and  10   x  into the terminal-holding holes  31  to be held thereby. 
     Next, as shown in  FIG. 14 ( b ) , a jig  60  is attached onto an upper surface of the housing  30 . A stepped contact surface  61  is provided on a lower surface of the jig  60 . When the alignment member  50  is attached from the lower surface of the housing  30  toward the substrate-side connecting parts  13  of the conductive terminals  10  and  10   x , the contact surface  61  of the jig  60  and the terminal holder  17  of the conductive terminal  10  abut to each other. Thereby, the alignment member  50  can be surely attached. 
     Next, as shown in  FIG. 14 ( c ) , the substrate-side connecting parts  13  of the plurality of conductive terminals  10  and  10   x  penetrate the through holes  55  of the alignment member  50 , and project downward from a lower surface of the alignment member  50 . And then, a jig  70  is attached toward the substrate-side connecting parts  13 . The jig  70  includes a plurality of opened holding recessed parts  71  into which distal ends  13   a  of the substrate-side connecting parts  13  of the plurality of conductive terminals  10  and  10   x  can be inserted, respectively. 
     Accordingly, as shown in  FIG. 14 ( c )  and  FIG. 15 ( a ) , when the jig  70  is attached in a state where the distal ends  13   a  of the plurality of conductive terminals  10  and  10   x  have been inserted into the holding recessed parts  71 , the substrate-side connecting parts  13  of the conductive terminals  10  and  10   x  are held not to move even if external force acts thereto. 
     After that, while the jigs  60  and  70  have been held as shown in  FIG. 14 ( d )  and  FIG. 15  ( b ), upon applying external force in a direction of arrow Z 1  from the back surface to the front surface of the alignment member  50 , the alignment member  50  horizontally slides toward the screen  34  of the housing  30 . The projecting shoulder part  15 , which has been located in the penetrating part  55   b  of the through hole  55  of the alignment member  50 , moves to fit into the recessed holding part  55   c  through processes mentioned below referring to  FIG. 16 . 
     When the alignment member  50  horizontally slides, the contact surface  61  of the jig  60  guides the terminal holder  17  of the conductive terminal  10 , and the height of the projecting shoulder part  15  can be set at a regular position. 
     More concretely, upon applying the external force in the direction of arrow Z 1  to the alignment member  50  in a state of  FIG. 16 ( a ) , an inclined plane  15   b  formed on a back edge of an upper surface  15   a  of the projecting shoulder part  15  of the conductive terminal  10 , abuts onto the guide surface  55   d  of the suspended part  55   g  as shown in  FIG. 16 ( b ) . 
     The inclined plane  15   b  and the guide surface  55   d  incline in the same direction. When the external force in the direction of arrow Z 1  is further applied, the guide surface  55   d  slides to run over the upper surface  15   a  along the inclined plane  15   b , whereby the projecting shoulder part  15  is pressed downward. At this time, a horizontal portion between the wide area  16  and the bent part  11  of the body part  10   a  (See,  FIG. 3 .) of the conductive terminal  10 , is elastically deformed to press the projecting shoulder part  15  downward. 
     After that, when the rear edges of the guide surfaces  55   d  have passed the front edge portion of the upper surface  15   a  of the projecting shoulder part  15 , downward pressing force against the projecting shoulder part  15  is released. Then, as shown in  FIG. 16 ( c )  and  FIG. 17 , the projecting shoulder part  15  rises toward the original position thereof to fit into the recessed holding part  55   c . In this way, attaching the alignment member  50  onto the housing  30  has been completed. 
     When the alignment member  50  is going to be attached to the housing  30 , the alignment member  50  is locked to the housing  30  between the side pieces  51  of the alignment member  50  and the outer side walls  35  of the housing  30  through processes as shown in  FIG. 18 . 
     More concretely, when the alignment member  50  is in the state of  FIG. 14 ( c )  with respect to the housing  30 , the side pieces  51  of the alignment member  50  and the outer side walls  35  of the housing  30  are in the state of  FIG. 18 ( a ) . That is, as shown in  FIG. 18 ( a ) , the lock parts  52  in a semi-cylindrical shape provided with both sides of the alignment member  50  are fitted into recessed grooves  39   a  formed on lower surfaces of the lock parts  39 . The lock parts  39  are provided with the recessed portions  40  formed on the outer side walls  35  of the housing  30 . 
     Next, as shown in  FIG. 18 ( b ) , when the external force in the direction of arrow Z 1  is applied to the alignment member  50 , the two lock parts  52  are fitted to front surface sides of the lock parts  39 , respectively. The left lock part  53  among the two lock parts  53  abuts onto the upper surface of the lock part  38 , and the right lock part  53  of the same also abuts onto the upper surface of the lock part  39 . Passing through processes as shown in  FIG. 18  enables to lock the side pieces  51  of the alignment member  50  and the outer side walls  35  of the housing  30  so as not to easily separate with each other. 
     Next, referring to Figs. from  19  to  21 , processes of attaching a circuit substrate  200  to the electrical connector  100  will now be explained. 
     As shown in  FIG. 19 , in the finished electrical connector  100 , the substrate-side connecting parts  13  of the plurality of conductive terminals  10  and  10   x , project downward from the lower surface of the alignment member  50 . Upon attaching the circuit substrate  200  to the electrical connector  100 , as shown in  FIG. 20  and  FIG. 21 ( a ) , an upper surface  30   b  of the housing  30  of the electrical connector  100  is set up in a state where the upper surface  30   b  abuts onto an inner surface  301  of a housing  300 . 
     The lower surface of the alignment member  50  exposes to the outside. And then, the circuit substrate  200  and a substrate press fitting jig  80 , are arranged onto the lower surface of the alignment member  50 . A plurality of through holes  201  have been opened through the circuit substrate  200  in the same arrangement as that of the substrate-side connecting parts  13  of the plurality of conductive terminals  10  and  10   x . A plurality of holes  81  (See,  FIG. 21 .) of the same arrangement as the plurality of through holes  201  have been also opened through the substrate press fitting jig  80 . 
     After that, pressing the circuit substrate  200  toward the electrical connector  100  using the substrate press fitting jig  80 , causes the plurality of substrate-side connecting parts  13  to be inserted into the through holes  201  of the circuit substrate  200 , respectively. When the substrate press fitting jig  80  is removed from the circuit substrate  200  after inserting the substrate-side connecting parts  13  into the through holes  201  has been completed, as shown in  FIG. 21 ( b ) , the contact portions  13   b  of the substrate-side connecting parts  13  are kept to be held within the through holes  201 . In this way, attaching the circuit substrate  200  to the electrical connector  100  is finished. 
     The electric connector  100  includes the alignment member  50  engaged by the housing  30  in the state where the substrate-side connecting parts  13  project from the through holes  55  used for inserting conductive-terminals therein. And, the uneven engaging mechanism which is an engaging unit preventing the substrate-side connecting parts  13  of the conductive terminals  10  and  10   x  from moving to the bent parts  11 , is provided between the projecting shoulder parts  15  of the conductive terminals  10  and the through holes  55 . 
     The uneven engaging mechanism includes: the projecting shoulder parts  15  provided with the conductive terminals  10  and  10   x ; and the recessed holding parts  55   c  provided within the through holes  55  of the alignment member  50 . 
     Accordingly, as shown in Figs. from  14  to  17 , when the alignment member  50  temporally engaged with the openings  30   a  of the housing  30  are made to slide in the direction crossing the substrate-side connecting parts  13  of the conductive terminals  10  and  10   x  (direction approaching to the screen  34  of the housing  30 ), the projecting shoulder parts  15  of the conductive terminals  10  and  10   x  engage with the recessed holding parts  55   c  within the through holes  55 , respectively. 
     Due to this, the substrate-side connecting parts  13  of the conductive terminals  10  and  10   x  are prevented from moving to the bent parts  11 . As shown in  FIG. 21 , the substrate-side connecting parts  13  of the conductive terminals  10  and  10   x , can be prevented from running to the bent parts  11  caused by press resistance upon attaching the circuit substrate  200  to the electrical connector  100 . 
     As shown in  FIG. 12 ,  FIG. 13 , and  FIG. 16 , when the alignment member  50  is made to slide in the direction crossing the substrate-side connecting parts  13 , the projecting shoulder parts  15  of the conductive terminals  10  and  10   x , are smoothly fitted into the recessed holding parts  55   e . This is because the guide surfaces  55   d  guiding the projecting shoulder parts  15  of the conductive terminals  10  and  10   x  toward the recessed holding parts  55   c , are provided on the lower surfaces of the suspended parts  55   g  between the inner peripheral surfaces and the recessed holding parts  55   c  of the through holes  55 . 
     The plurality of contact portions  13   b  including the press-fit mechanism, are provided with the substrate-side connecting parts  13  of the conductive terminals  10  and  10   x . Accordingly, the circuit substrate  200  can be easily inserted into the through holes  201 , and contact reliability after the insertion is also excellent. 
     Since the lock mechanism as shown in  FIG. 18  is provided between the side pieces  51  of the alignment member  50  and the outer side walls  35  of the housing  30 , the alignment member  50  attached with the openings  30   a  of the housing  30 , can be prevented from undesired removing therefrom.
