The first mold  21  is formed by the first base  31 , the first front wall  32 , the first left side wall  33 , and the first right side wall  34  in a box shape having a first opening  36  that opens to the rear and the upper part. 
     Hereinbelow, a first direction along the axis of a rotating shaft  58  provided in the second connector  12  is shown as the X direction. A second direction orthogonal to the X direction and extending along the first base  31  is shown as the Y direction. Further, a third direction orthogonal to the X direction and orthogonal to the Y direction is indicated by the Z direction. 
     The X direction may be described as the left-right direction, the Y direction as the front-back direction, and the Z direction as the up-down direction. Further, in the Y direction, the first connector  11  side may be described as the front side, and the second connector  12  side may be described as the rear side. In addition, in the X direction, the left side of the first space block  23  as viewed from the front of the first connector  11  may be described as the left direction, and the right side of the first space block  23  may be described as the right direction. 
     The first base  31  is formed in a flat rectangular shape. The first front wall  32  is raised upward from the front side of the first base  31  so as to be orthogonal to the first base  31 . The first left side wall  33  is provided on the left side of the first base  31  and the left side of the first front wall  32 , and a left recess  38  is formed on the side of the first opening  36 . The first right side wall  34  is provided on the right side of the first base  31  and the right side of the first front wall  32 , and a right recess  39  is formed on the side of the first opening  36 . 
     The first guide  22  is provided on the inner surface of the first right side wall  34 . The first left side wall  33  is provided with the first guide  22  on the inner surface like the first right side wall  34 . The first guide  22  of the first right side wall  34  and the first guide  22  of the first left side wall  33  are symmetrical portions. For this reason, each part of the first guide  22  of the first left side wall  33  is designated by the same reference numerals as the first guide  22  of the first right side wall  34 , and so a detailed description of the first guide  22  of the first left side wall  33  will be omitted. 
     The first guide  22  is provided with a first guide groove  42 , a second guide groove  43 , and a third guide groove  44 . The first guide groove  42  is formed in a concave groove that opens on the inner surface of the first right side wall  34 . The first guide groove  42  extends in the Y direction from the rear side  34   a  of the first right side wall  34  to the portion  34   b  near the front side. 
     The second guide groove  43  is formed in a concave groove that opens on the inner surface of the first right side wall  34 . The second guide groove  43  extends in the Z direction from the right recess  39  to the bottom side  34   d  of the first right side wall  34  at the portion  34   c  near the rear side of the first right side wall  34 . 
     The third guide groove  44  is formed in a concave groove that opens on the inner surface of the first right side wall  34 . The third guide groove  44  extends in the Z direction from the upper side  34   e  of the first right side wall  34  to the bottom side  34   d  of the first right side wall  34  at the portion  34   b  near the front side of the first right side wall  34 . 
     The first space block  23  is provided on the inner surface of the first front wall  32 . The first space block  23  projects from the center in the X direction toward the rear in the Y direction at the inner surface of the first front wall  32 . The first space block  23  is formed with a first space  47  that opens to the rear surface  23   a . An outer circumference  47   a  of the first space  47  is formed in an arc shape. 
     A plurality of spacers  49  are formed between the first space block  23  and the first left side wall  33  at intervals in the X direction. Further, a plurality of the spacers  49  are formed between the first space block  23  and the first right side wall  34  at intervals in the X direction. 
     A first contact pin  24  is supported between the spacer  49  and the spacer  49  that are adjacent. As shown in  FIG. 4 , the first contact pin  24  is formed of, for example, an electrically conductive elastic member and has a columnar cross section, and has a first base portion  24   a  and a first contact portion  24   b . The first base portion  24   a  is raised from the first base  31  along the first front wall  32  in a state of being fixed to the first base  31 . In this state, as shown in  FIG. 3 , a part of the first base portion  24   a  protrudes outward from the first base  31 . 
     The first contact portion  24   b  is bent in a curved shape downward from the vicinity of the tip portion of the first base portion  24   a . A tip portion  24   c  of the first contact portion  24   b  is arranged along the first base portion  24   a  at intervals in the Y direction with respect to the first base portion  24   a.    
     In this state, when a pressing force (pressing) is applied frontward to the first contact portion  24   b , the first contact portion  24   b  is elastically deformed toward the first base portion  24   a.    
     As shown in  FIGS. 5 and 6 , the second connector  12  is configured to be couplable (insertable) to the first connector  11  (see also  FIG. 2 ). 
     The second connector  12  is provided with a second mold  51 , a second guide  52 , a second space block  53 , a second contact pin (second terminal)  54 , a fixed component  55 , a standard contact (contactor)  56 , a precharge contactor (contactor)  57  and the rotating shaft  58 . 
     The second mold  51  has a second base  61 , a second rear wall  62 , a second left side wall  63 , and a second right side wall  64 . The second mold  51  is formed by a second base  61 , a second rear wall  62 , a second left side wall  63 , and a second right side wall  64  in a box shape having a second opening  65  that opens to the front and the upper part. 
     The second base  61  is formed in a flat rectangular shape. The second rear wall  62  rises upward from the rear side of the second base  61  so as to be orthogonal to the second base  61 . The second left side wall  63  is provided on the left side of the second base  61  and the left side of the second rear wall  62 . The second right side wall  64  is provided on the right side of the second base  61  and the right side of the second rear wall  62 . 
     The second left side wall  63  is provided with the second guide  52  on the outer surface. The second right side wall  64  is provided with the second guide  52  on the outer surface, similarly to the second left side wall  63 . The second guide  52  of the second left side wall  63  and the second guide  52  of the second right side wall  64  are left-right symmetrical portions. Therefore, the second guide  52  of the second right side wall  64  and the second guide  52  of the second left side wall  63  are designated by the same reference numerals, and so a detailed description of the second guide  52  of the second right side wall  64  will be omitted. 
     The second guide  52  is a convex guide that protrudes outward from the second left side wall  63  and extends in the Y direction from the front side  63   a  to the rear side  63   b  of the second left side wall  63 . The second guide  52  of the second left side wall  63  is formed so as to be movable in the Y direction along the first guide groove  42  of the first left side wall  33  in a state of being housed (locked) in the first guide groove  42  (see  FIG. 2 ) of the first left side wall  33  of the first mold  21 . 
     The second guide  52  of the second right side wall  64  is movably locked in the Y direction along the first guide groove  42  of the first right side wall  34  in a state of being housed in the first guide groove  42  (see  FIG. 2 ) of the first right side wall  34  of the first mold  21 . 
     As shown in  FIG. 2 , the second mold  51  is coupled to the first mold  21 . The second mold  51  is formed to be insertable from the first opening  36  of the first mold  21  into the interior of the first mold  21  in the Y direction (that is, in the front direction). 
     The first guide  22  and the second guide  52  are not limited to the shape of the embodiment, and can be made to have other shapes. 
     As shown in  FIGS. 2, 7, and 8 , the second space block  53  is provided on the inner surface of the second rear wall  62 . The second space block  53  projects from the center in the X direction forward in the Y direction until a front end  61   a  of the second base  61  at the inner surface of the second rear wall  62 . A second space  66  that opens to a front surface  53   a  is formed in the second space block  53 . An outer circumference  66   a  of the second space  66  is formed in an arc shape. 
     The second space block  53  is arranged at a position where the front surface  53   a  thereof makes contact with the rear surface  23   a  of the first space block  23  (see also  FIG. 3 ) in a state of the second mold  51  being inserted into the first mold  21 . In this state, a fixed space  46  is formed by the second space  66  and the first space  47 . An outer circumference  46   a  of the fixed space  46  is formed in an arc shape by the outer circumference  47   a  of the first space  47  and the outer circumference  66   a  of the second space  66 . 
     Returning to  FIGS. 5 and 6 , a plurality of second contact pins  54  are supported between the second space block  53  and the second left wall  63  at intervals in the X direction. A plurality of the second contact pins  54  are supported between the second space block  53  and the second right side wall  64  at intervals in the X direction. 
     As shown in  FIG. 6 , the second contact pin  54  is formed of, for example, an electrically conductive elastic member and has a columnar cross section, and has a second base portion  54   a  and a second contact portion  54   b . The second base portion  54   a  extends in the Y direction from the second rear wall  62  along the second base  61  in a state of being fixed to the second rear wall  62 . In this state, as shown in  FIG. 5 , a part of the second base portion  54   a  protrudes outward from the second rear wall  62 . 
     The second contact portion  54   b  is bent in a curved shape rearward from around the tip portion of the second base portion  54   a . A tip portion  54   c  of the second contact portion  54   b  is arranged along the second base portion  54   a  at an interval in the Z direction (upward) with respect to the second base portion  54   a.    
     In this state, when a pressing force (pressing) acts downward on the second contact portion  54   b , the second contact portion  54   b  elastically deforms toward the second base portion  54   a.    
     As shown in  FIGS. 6 to 8 , the fixed component  55  is housed in the fixed space  46  of the first space block  23  and the second space block  53 . The rotating shaft  58  penetrates a center  55   a  of the fixed component  55 , which is fixed in a state of being orthogonal to the rotating shaft  58 . An outer circumference  55   b  of the fixed component  55  is formed in a circular shape when viewed from the axial direction (that is, the X direction) of the rotating shaft  58 , and a fixed recess (recess)  68  is formed in a portion of the outer circumference  55   b . The fixed recess  68  is formed in a concave shape from the outer circumference  55   b  toward the center  55   a.    
     Therefore, the entire fixed component  55  is housed in the second space  66  of the second space block  53  in a state where the fixed recess  68  of the fixed component  55  faces the front surface  53   a  of the second space block  53 . Hereinbelow, this state may be described as a storage position. 
     For example, the fixed component  55  may have the fixed recess  68  so as to maintain non-contact with the first space block  23  and the first contact pin  24  when coupling the first connector  11  and the second connector  12 . 
     That is, by having the fixed recess  68 , the fixed component  55  is kept so as to not be in contact with the first space block  23  and the first contact pin  24  in the state of being arranged in the storage position. Thereby, when the second connector  12  is coupled (connected) to the first connector  11 , the fixed component  55  can be kept so as not to be in contact with the first space block  23  and the first contact pin  24 . 
     The fixed component  55  is stored in the first space block  23  and the second space block  53  so as to be rotatable in a state where the second mold  51  is coupled to the first mold  21 . Specifically, the fixed component  55  is arranged in a rotatable state in the fixed space  46  formed by the first space  47  of the first space block  23  and the second space  66  of the second space block  53 . 
     The fixed component  55  and the fixed space  46  are formed in a shape that does not cause misalignment or slip off between the first space block  23  and the second space block  53  in a state where the fixed component  55  rotates in the fixed space  46 . In other words, the first mold  21  and the second mold  51  can be held in an accurate coupled state in the state of preventing the occurrence of misalignment or slip off between the first mold  21  and the second mold  51  by rotating the fixed component  55  in the fixed space  46 . 
     In the embodiment, a shape in which the fixed component  55  is made to protrude from the first space block  23  and the second space block  53  will be described as an example. However, it is also possible to have a shape in which the fixed component  55  is not made to protrude from the first space block  23  and the second space block  53 . 
     In the embodiment, an example in which the second connector  12  is provided with one fixed component  55  will be described, but the number of fixed components  55  is not limited to one. As another example, for example, it is possible to include two or more fixed components  55 . By increasing the number of fixed components  55  to two or more, it is possible to more satisfactorily prevent the occurrence of misalignment or slip off between the first mold  21  and the second mold  51 . 
     As shown in  FIGS. 9 to 11 , the rotating shaft  58  is provided with a standard contactor  56  and the precharge contactor  57 . The standard contactor  56  is provided with a standard base (base)  71  and a standard conductor (conductor)  72 . 
     The standard base  71  is formed of, for example, an insulator having a substantially triangular shape (fan shape) formed by a first curved side  71   a , a second curved side  71   b , and a third curved side  71   c . The first curved side  71   a  is formed, for example, in a curved shape protruding outward, with the length of the arc being set to a dimension L 1 . The second curved side  71   b  and the third curved side  71   c  are arranged, for example, at an angle θ 1  from each other, and are formed in a curved shape protruding outward. 
     The standard base  71  has a standard groove portion (groove portion)  74  formed over the entire outer circumference. The standard groove portion  74  is formed so as to be able to fit the first contact portion  24   b  (see  FIG. 4 ) of the first contact pin and the second contact portion  54   b  (see  FIG. 6 ) of the second contact pin  54 . 
     Further, according to  FIG. 11 , the standard base  71  is fixed in a state orthogonal to the rotating shaft  58  by the rotating shaft  58  penetrating through a portion  71   d  of the standard base  71  in the vicinity where the second curved side  71   b  and the third curved side  71   c  intersect. 
     Here, in a state where the fixed component  55  is arranged at the storage position, the second curved side  71   b  is arranged at a position facing the first contact portion  24   b , and the third curved side  71   c  is arranged at a position facing the second contact portion  54   b . In this state, the second curved side  71   b  is kept in non-contact with the first contact portion  24   b , and the third curved side  71   c  is kept in non-contact with the second contact portion  54   b.    
     Thereby, when the second connector  12  is coupled (connected) to the first connector  11 , the standard base  71  (that is, the standard contactor  56 ) can be kept in a state of non-contact with respect to the first contact portion  24   b  and the second contact portion  54   b.    
     The standard conductor  72  is provided on the first curved side  71   a  of the standard base  71 . The standard conductor  72  is formed in a groove shape along the standard groove portion  74  of the first curved side  71   a . Therefore, by being fitted to the first contact portion  24   b  (see  FIG. 4 ) and the second contact portion  54   b  (see  FIG. 6 ), the standard conductor  72  can be brought into stable contact therewith. By being brought into simultaneous contact with the first contact portion  24   b  and the second contact portion  54   b , the standard conductor  72  becomes electrically conductive with the first contact pin  24  and the second contact pin  54 . 
     Here, as described above, the rotating shaft  58  is fixed to the portion  71   d  of the standard base  71  in the vicinity where the second curved side  71   b  and the third curved side  71   c  intersect. Therefore, the rotating shaft  58  is provided at a position offset in the direction away from the standard conductor  72 . As a result, the standard contactor  56  rotates together with the rotating shaft  58 , whereby the standard conductor  72  can be brought into contact with the first contact portion  24   b  and the second contact portion  54   b.    
     By forming the standard base  71  with an insulator, the standard conductor  72  can be brought into contact with the first contact portion  24   b  and the second contact portion  54   b  with high accuracy. Thereby, the timing accuracy of conduction can be improved. 
     As shown in  FIG. 10 , among the plurality of standard contactors  56 , the precharge contactor  57  is provided on the inner side in the left-right direction of the outermost standard contactor  56  in the left direction. Further, the standard contactor  56  is provided on the inner side of the precharge contactor  57  in the left-right direction. That is, the precharge contactor  57  is arranged between the outermost standard contactor  56  in the left direction and another standard contactor  56 . 
     As shown in  FIGS. 9, 10 and 12 , the precharge contactor  57  is provided with a precharge base (base)  76  and a precharge conductor (conductor)  77 . The precharge base  76  is for example formed of an insulator having a substantially triangular shape (fan shape) formed by a first precharge curved side  76   a , a second precharge curved side  76   b , and a third precharge curved side  76   c  similarly to the standard base  71  of the standard contactor  56 . The first precharge curved side  76   a  is formed, for example, in a curved shape protruding outward, and the length of the arc is set to a dimension L 2 . The second precharge curved side  76   b  and the third precharge curved side  76   c  are formed, for example, in a curved shape that protrudes outward at an angle θ 2  from each other. 
     The length dimension L 2  of the first precharge curved side  76   a  is set larger than the length dimension L 1  of the first curved side  71   a . The angle θ 2  between the second precharge curved side  76   b  and the third precharge curved side  76   c  is set to be larger than the angle θ 1  between the second curved side  71   b  and the third curved side  71   c.    
     The precharge base  76  has a precharge groove portion (groove portion)  78  formed over the entire outer circumference. The precharge groove portion  78  is formed so as to be able to fit the first contact portion  24   b  (see  FIG. 4 ) of the first contact pin and the second contact portion  54   b  (see  FIG. 6 ) of the second contact pin  54 . 
     Moreover, according to  FIG. 12 , the precharge base  76  is fixed in a state orthogonal to the rotating shaft  58  by the rotating shaft  58  penetrating through a portion  76   d  of the precharge base  76  in the vicinity where the second precharge curved side  76   b  and the third precharge curved side  76   c  intersect. 
     Here, in a state where the fixed component  55  is arranged at the storage position, the second precharge curved side  76   b  is arranged at a position facing the first contact portion  24   b , and the third precharge curved side  76   c  is arranged at a position facing the second contact portion  54   b . In this state, the second precharge curved side  76   b  is kept in non-contact with the first contact portion  24   b , and the third precharge curved side  76   c  is kept in non-contact with the second contact portion  54   b.    
     Thereby, when the second connector  12  is coupled (connected) to the first connector  11 , the precharge base  76  (that is, the precharge contactor  57 ) can be kept in a state of non-contact with respect to the first contact portion  24   b  and the second contact portion  54   b.    
     The precharge conductor  77  is provided on the first precharge curved side  76   a  of the precharge base  76 . The precharge conductor  77  is formed in a groove shape along the precharge groove portion  78  of the first precharge curved side  76   a . Therefore, by being fitted to the first contact portion  24   b  (see  FIG. 4 ) and the second contact portion  54   b  (see  FIG. 6 ), the precharge conductor  77  can be brought into stable contact therewith. By being brought into simultaneous contact with the first contact portion  24   b  and the second contact portion  54   b , the precharge conductor  77  becomes electrically conductive with the first contact pin  24  and the second contact pin  54 . 
     Here, as described above, the rotating shaft  58  is fixed to the portion  76   d  of the precharge base  76  in the vicinity where the second precharge curved side  76   b  and the third precharge curved side  76   c  intersect. Therefore, the rotating shaft  58  is provided at a position offset in the direction away from the precharge conductor  77 . As a result, the precharge contact element  57  rotates along with the rotating shaft  58 , whereby the precharge conductor  77  can be brought into contact with the first contact portion  24   b  and the second contact portion  54   b.    
     By forming the precharge base  76  with an insulator, the precharge conductor  77  can be brought into contact with the first contact portion  24   b  and the second contact portion  54   b  with high accuracy. Thereby, the timing accuracy of conduction can be improved. 
     As shown in  FIGS. 11 and 12 , when the precharge contactor  57  is compared to the standard contactor  56 , the dimension L 2  of the arc length of the first precharge curved side  76   a  is set to be larger than the dimension L 1  of the arc length of the first curvature side  71   a  of the standard contactor  56 . Further, the angle θ 2  of the precharge contactor  57  is set to be larger than the angle θ 1  of the standard contactor  56 . 
     Therefore, the precharge conductor  77  of the precharge contactor  57  extends in the clockwise direction (arrow A direction) by a dimension L 3  protruding with respect to the standard conductor  72 . As a result, when the rotating shaft  58  rotates in the clockwise direction, the precharge conductor  77  makes contact with the first contact portion  24   b  (see  FIG. 4 ) and the second contact portion  54   b  (see  FIG. 6 ) earlier as compared with the standard conductor  72 . That is, in the precharge contactor  57 , when the rotating shaft  58  is rotated in the clockwise direction, the timing at which the first contact pin  24  and the second contact pin  54  are connected by the precharge conductor  77  is changed with respect to the timing by the standard conductor  72 . That is, the timing at which the first contact pin  24  and the second contact pin  54  are connected differs between the standard contactor  56  and the precharge contactor  57  as the rotating shaft  58  rotates. 
     As shown in  FIGS. 6 and 9 , the fixed component  55 , the standard contactor  56 , and the precharge contactor  57  are integrally coupled to the rotating shaft  58 . The rotating shaft  58  is rotatably supported in a state of penetrating the second left side wall  63  of the second mold  51 , the second space block  53 , and the second right side wall  64  of the second mold  51  in the X direction (left-right direction). In this state, the standard contactor  56  and the precharge contactor  57  are arranged in the space between the second left side wall  63  and the second space block  53  so as to be rotatable together with the rotating shaft  58 . In the space between the second space block  53  and the second right side wall  64 , the standard contactor  56  is arranged in a rotatable state together with the rotating shaft  58 . Further, in the second space  66  of the second space block  53 , the fixed component  55  is arranged in a rotatable state together with the rotating shaft  58 . 
     When the rotating shaft  58  rotates in the clockwise direction (arrow A direction), for example, the standard contactor  56 , the precharge contactor  57 , and the fixed component  55  rotate clockwise together with the rotating shaft  58 . 
     As the standard contactor  56  rotates in the clockwise direction, the standard conductor  72  makes contact with the first contact portion  24   b  of the first contact pin  24  (see  FIG. 4 ) and the second contact portion  54   b  of the second contact pin  54 . As a result, the first contact pin  24  and the second contact pin  54  can be made electrically conductive by the standard conductor  72 . 
     Further, as the precharge contactor  57  rotates in the clockwise direction, the precharge conductor  77  makes contact with the first contact portion  24   b  of the first contact pin  24  (see  FIG. 4 ) and the second contact portion  54   b  of the second contact pin  54 . Thereby, the first contact pin  24  and the second contact pin  54  can be made electrically conductive by the precharge conductor  77 . 
     Here, the precharge conductor  77  of the precharge contactor  57  extends in the clockwise direction by the protruding dimension L 3  with respect to the standard conductor  72  of the standard contactor  56 . As a result, in the state of the rotating shaft  58  being rotated in the clockwise direction, the timing at which the first contact pin  24  and the second contact pin  54  are brought into electrical conductivity (connected) by the precharge conductor  77  is changed with respect to the timing of being brought into electrical conductivity by the standard conductor  72  of the standard contactor  56 . 
     Next, an example of coupling (assembling) the second connector  12  to the first connector  11  of the contactor rotary connector  10  will be described with reference to  FIGS. 1 and 2 . 
     As shown in  FIG. 2 , the second mold  51  is inserted toward the first opening  36  of the first mold  21  in the Y direction (specifically, in the arrow B direction). The second guide  52  formed on the second right side wall  64  of the second mold  51  is locked in the state of being housed in the first guide groove  42  formed on the first right side wall  34  of the first mold  21 . 
     Similarly, the second guide  52  formed on the second left side wall  63  of the second mold  51  is locked in the state of being housed in the first guide groove  42  (see  FIG. 3 ) formed on the first left side wall  33  of the first mold  21 . 
     In this state, the second mold  51  is inserted into the inside of the first mold  21  from the first opening  36  of the first mold  21 . The second mold  51  inserted inside the first mold  21  is continuously inserted in the direction of arrow B toward the first space block  23 . 
     In this state, the left end of the rotating shaft  58  moves to the left recess  38  of the first left side wall  33 , and the right end of the rotating shaft  58  moves to the right recess  39  of the first right side wall  34 . 
     As shown in  FIG. 1 , the front surface  53   a  formed on the second space block  53  of the second mold  51  contacts the rear surface  23   a  formed on the first space block  23  of the first mold  21 . In this state, the second mold  51  is kept inserted inside the first mold  21 . 
     In this way, the first guide groove  42  is formed in the first mold  21 , and the second guide  52  is formed in the second mold  51 . As a result, the second mold  51  can be smoothly inserted into the first mold  21  by accommodating the second guide  52  in the first guide groove  42 . That is, the second connector  12  can be smoothly inserted into and coupled with the first connector  11 . 
     Here, in general, when a circuit board is inserted into or removed from a device in operation, the circuit board is tilted, whereby a contact pin of the connector may come into contact with an adjacent contact pin. In order to prevent this, it was necessary to float the circuit board during insertion and removal of the circuit board. 
     Therefore, as shown in  FIGS. 3 and 6 , by arranging the fixed component  55  in the storage position, the fixed component  55  is kept in non-contact with the first space block  23  and the first contact pin  24 . Further, the second curved side  71   b  (see  FIG. 11 ) is kept in non-contact with the first contact portion  24   b . In addition, the second precharge curved side  76   b  (see  FIG. 12 ) is kept in non-contact with the first contact portion  24   b . Thereby, the second mold  51  can be smoothly inserted into the first mold  21 . 
     Moreover, a key or the like is attached to an end of the rotating shaft  58 , and the key and the rotating shaft  58  are operated in conjunction with each other. This makes it possible to realize a function in addition to a connector fixing operation, such as preventing unauthorized removal of the connector (circuit board). 
     Next, an example of rotating the fixed component  55  of the contactor rotary connector  10  will be described with reference to  FIG. 1  and  FIGS. 13A to 13C . 
     As shown in  FIGS. 1 and 13A , when the second mold  51  is inserted into the first mold  21 , the fixed component  55  is rotatably stored in the fixed space  46  of the first space block  23  and the second space block  53 . As the rotating shaft  58  rotates in the clockwise direction, the fixed component  55  rotates in the clockwise direction in the fixed space  46 . 
     As shown in  FIGS. 13B and 13C , as a result of the rotation of the fixed component  55  in the clockwise direction, the occurrence of misalignment or slip off between the first space block  23  and the second space block  53  can be prevented by the fixed component  55 . As a result, the first mold  21  and the second mold  51  can be held in an accurately inserted (coupled) state, in the state of misalignment or slip off between the first mold  21  and the second mold  51  being prevented by the rotation of the fixed component  55  in the clockwise direction. 
     Next, the operation of bringing the first contact pin  24  and the second contact pin  54  into electrical conduction will be described with reference to  FIG. 1  and  FIGS. 13 to 16 . In  FIGS. 14 to 16 , the first contact pin  24  with which the precharge contactor  57  makes contact is described as “one first contact pin  24 ”, and the first contact pin  24  with which the standard contactor  56  makes contact is described as “the other first contact pin  24 ”. The second contact pin  54  with which the precharge contactor  57  makes contact is described as “one second contact pin  54 ”, and the second contact pin  54  with which the standard contactor  56  makes contact is described as “the other second contact pin  54 ”. 
     As shown in  FIGS. 1 and 14A , with the second mold  51  inserted in the first mold  21 , the rotating shaft  58  rotates in the clockwise direction (arrow A direction). Therefore, the standard contactor  56  and the precharge contactor  57  rotate in the clockwise direction toward the first contact portion  24   b.    
     As shown in  FIGS. 1 and 14B , one end  77   a  of the precharge conductor  77  of the precharge contactor  57  comes into contact with one first contact portion  24   b . Here, the fixed component  55  rotates in the clockwise direction together with the rotating shaft  58  in the fixed space  46  (see  FIGS. 13A to 13C ). Therefore, misalignment or slip off between the first mold  21  and the second mold  51  is prevented from occurring. That is, the precharge contactor  57  is accurately positioned with respect to one first contact portion  24   b . As a result, the one end  77   a  of the precharge conductor  77  can be stably brought into contact (connection) with one first contact portion  24   b.    
     Therefore, the precharge conductor  77  exerts a pressing force (pressing) on the one first contact portion  24   b  toward one first base portion  24   a , and the one first contact portion  24   b  elastically deforms toward the one first base portion  24   a . As a result, a repulsive force is generated in the one first contact pin  24 , and the repulsive force of the one first contact pin  24  keeps the one first contact portion  24   b  in a state of stable contact with the one end  77   a  of the precharge conductor  77 . 
     As shown in  FIGS. 1 and 15A , the precharge conductor  77  continuously rotates in the clockwise direction in a state of being in contact with the one first contact portion  24   b . As the standard contactor  56  continuously rotates in the clockwise direction, one end  72   a  of the standard conductor  72  comes into contact with the other first contact portion  24   b.    
     Here, the fixed component  55  rotates in the clockwise direction together with the rotating shaft  58  in the fixed space  46  (see  FIGS. 13A to 13C ). Therefore, the occurrence of misalignment or slip off between the first mold  21  and the second mold  51  is prevented. That is, the standard contactor  56  is accurately positioned with respect to the other first contact portion  24   b . As a result, the one end  72   a  of the standard conductor  72  can be stably brought into contact (connection) with the other first contact portion  24   b.    
     Therefore, the standard conductor  72  exerts a pressing force (pressing) on the other first contact portion  24   b  toward the first base portion  24   a , and the other first contact portion  24   b  elastically deforms toward the other first base portion  24   a . As a result, a repulsive force is generated in the other first contact pin  24 , and the repulsive force of the other first contact pin  24  keeps the other first contact portion  24   b  in a state of stable contact with the one end  72   a  of the standard conductor  72 . 
     As shown in  FIG. 15B , the precharge contactor  57  and the standard contactor  56  are continuously rotated in the clockwise direction. The one end  77   a  of the precharge conductor  77  of the precharge contactor  57  makes contact with one second contact portion  54   b.    
     Therefore, the precharge conductor  77  exerts a pressing force (pressing) on the one first contact portion  24   b  toward one first base portion  24   a , and the one first contact portion  24   b  elastically deforms toward the one first base portion  24   a . As a result, a repulsive force is generated in the one first contact pin  24 , and the repulsive force of the one first contact pin  24  keeps the one first contact portion  24   b  in a state of stable contact with the one end  77   a  of the precharge conductor  77 . 
     The precharge conductor  77  exerts a pressing force (pressing) on one second contact portion  54   b  toward one second base portion  54   a , and the one second contact portion  54   b  elastically deforms toward the one second base portion  54   a . As a result, a repulsive force is generated in the one second contact pin  54 , and the repulsive force of the one second contact pin  54  keeps the one second contact portion  54   b  in a state of stable contact with the one end  77   a  of the precharge conductor  77 . 
     In this state, the one first contact pin  24  and the one second contact pin  54  are brought into electrical conductivity (connected) by the precharge conductor  77 . 
     As shown in  FIG. 16 , the precharge contactor  57  and the standard contactor  56  are continuously rotated in the clockwise direction. The one end  72   a  of the standard conductor  72  of the standard contactor  56  makes contact with the other second contact portion  54   b.    
     Therefore, the standard conductor  72  exerts a pressing force (pressing) on the other second contact portion  54   b  toward the other second base portion  54   a , and the other second contact portion  54   b  elastically deforms toward the other second base portion  54   a . As a result, a repulsive force is generated in the other second contact pin  54 , and the repulsive force of the other second contact pin  54  keeps the other second contact portion  54   b  in a state of stable contact with one end  72   a  of the standard conductor  72 . 
     In this state, the other first contact pin  24  and the other second contact pin  54  are brought into electrical conductivity (connected) by the standard conductor  72 . 
     In this way, the timing at which the one first contact pin  24  and the one second contact pin  54  are brought into electrical conductivity by the precharge contactor  57 , and the timing at which the other first contact pin  24  and the other second contact pin  54  are brought into electrical conductivity by the standard contactor  56  can be made to differ. Further, the timing of disconnecting the conductivity between the one first contact pin  24  and the one second contact pin  54  and the timing of disconnecting the conductivity between the other first contact pin  24  and the other second contact pin  54  can be made to differ. 
     That is, according to the standard contactor  56  and the precharge contactor  57 , the conduction timing and the disconnection timing between the first contact pin  24  and the second contact pin  54  can be made to differ without changing the shapes or installation locations of the first contact pin  24  and the second contact pin  54 . 
     In general, the contact pins are integrated with the connector molds, with the contact control of the contact pins being the same as the fitting operation of the connectors, and so the connection operation of the contact pins could not be controlled separately. For this reason, the connection between the power supply system and the signal system is the same as a physical operation, and so in order to change the connection timing of each, it was necessary to separately control the connection by an electrical circuit prepared on the circuit board. 
     Therefore, the standard contactor  56  and the precharge contactor  57  are used to make the conduction timing and the disconnection timing of the first contact pins  24  and the second contact pins  54  different. 
     In this way, the connection operation and timing of the first contact pin  24  and the second contact pin  54  can be changed by the shape of the contactor for each contact pin to be connected. Thereby it is possible to change the connection timing of the power supply pin and the signal pin of the circuit board, realize a precharge operation, and eliminate the signal line connection control circuit when connecting the connectors. 
     It is possible to individually control the timing of the coupling (insertion) operation of the first connector  11  and the second connector  12  and the connection operation of the first contact pin  24  and the second contact pin  54 . As a result, when inserting a circuit board or the like into a device in operation, it is possible to prevent contact between the adjacent first contact pin  24  and the second contact pin  54  caused by oblique insertion of the circuit board. 
     Hereinbelow, contactor rotary connectors of the second to sixth embodiments will be described with reference to  FIGS. 17 to 21 . In the contactor rotary connectors of the second to sixth embodiments, the same members as those of the contactor rotary connector  10  of the first embodiment and similar members are designated by the same reference numerals, and detailed descriptions thereof will be omitted. 
     Second Embodiment 
     As shown in  FIG. 17A , the contactor rotary connector  100  is provided with a second guide  102  on the second left side wall  63  and the second right side wall  64  of the second mold  51 . Other configurations are the same as those of the contactor rotary connector  10  of the first embodiment. 
     The second guide  102  of the second left wall  63  and the second guide  102  of the second right wall  64  are symmetrical parts. Therefore, the second guide  102  of the second right side wall  64  and the second guide  102  of the second left side wall  63  are designated by the same reference numeral, and a detailed description of the second guide  102  of the second right side wall  64  will be omitted. 
     The second guide  102  is provided with a first convex guide  103  and a second convex guide  104 . The first convex guide  103  projects outward from the second left side wall  63  at a portion near the rear side  63   b  of the second left side wall  63 . The first convex guide  103  extends from the bottom  63   c  of the second left side wall  63  toward the center of the second left side wall  63  in the Z direction (upward). The first convex guide  103  is formed to be movable in the Z direction along the second guide groove  43  of the first left side wall  33  in a state of being housed (locked) in the second guide groove  43  of the first left side wall  33 . 
     The second convex guide  104  projects outward from the second left side wall  63  at the front side  63   a  of the second left side wall  63 . The second convex guide  104  extends from the bottom side  63   c  of the second left side wall  63  toward the upper side  63   d  of the second left side wall  63  in the Z direction (upward). The second convex guide  104  is formed to be movable in the Z direction along the third guide groove  44  of the first left side wall  33  in a state of being housed (locked) in the third guide groove  44  of the first left side wall  33 . 
     Next, an example in which the second connector  12  is coupled (assembled) to the first connector  11  in the contactor rotary connector  100  of the second embodiment will be described with reference to  FIGS. 17A and 17B . 
     As shown in  FIG. 17A , the second mold  51  is inserted toward the first opening  36  of the first mold  21  in the Z direction (specifically, the arrow C direction). The first convex guide  103  and the second convex guide  104  formed on the second right side wall  64  of the second mold  51  are locked in a state of being housed in the second guide groove  43  and the third guide groove  44  formed in the first right side wall  34  of the first mold  21 . 
     Similarly, the first convex guide  103  and the second convex guide  104  formed on the second left side wall  63  of the second mold  51  are locked in a state of being housed in the second guide groove  43  and the third guide groove  44  formed in the first left side wall  33  of the first mold  21 . 
     In this state, the second mold  51  is inserted into the inside of the first mold  21  from the first opening  36  of the first mold  21 . The second mold  51  inserted inside the first mold  21  is continuously inserted in the direction of arrow C toward the first base  31 . 
     In this state, the left end of the rotating shaft  58  moves to the left recess  38  of the first left side wall  33 , and the right end of the rotating shaft  58  moves to the right recess  39  of the first right side wall  34 . 
     As shown in  FIG. 17B , the front surface  53   a  formed on the second space block  53  of the second mold  51  contacts the rear surface  23   a  formed on the first space block  23  of the first mold  21 . In this state, the second mold  51  is kept in a state of insertion in the first mold  21 . 
     As described above, the second guide groove  43  and the third guide groove  44  are formed in the first mold  21 , and the first convex guide  103  and the second convex guide  104  are formed on the second mold  51 . Thereby, the first convex guide  103  and the second convex guide  104  are housed in the second guide groove  43  and the third guide groove  44 , whereby the second mold  51  can be smoothly inserted into the first mold  21 . That is, the second connector  12  can be smoothly inserted into and coupled with the first connector  11 . 
     Third Embodiment 
     As shown in  FIG. 18A , the contactor rotary connector  110  is provided with a first guide  112  in the first mold  21  and a second guide  113  in the second mold  51 . Other configurations are the same as those of the contactor rotary connector  10  of the first embodiment. 
     The first guide  112  protrudes inward from the inner surface of the first base  31  in the first mold  21  and extends in the X direction (left-right direction). The second guide  113  is formed in a concave groove that opens to the outer surface of the second base  61  in the second mold  51  and can be fitted (locked) to the first guide  112 . Like the first guide  112 , the second guide  113  extends in the X direction (left-right direction). The second guide  113  is formed so as to be movable in the X direction along the first guide  112  in a state of being fitted (locked) to the first guide  112 . 
     Next, an example in which the second connector  12  is coupled (assembled) to the first connector  11  in the contactor rotary connector  110  of the third embodiment will be described with reference to  FIGS. 18A and 18B . 
     As shown in  FIG. 18A , the second mold  51  is inserted in the X direction (specifically, the arrow D direction) toward the first opening  36  of the first mold  21 . The second guide  113  of the second mold  51  is locked in a state of being fitted (locked) to the first guide  112  of the first mold  21 . 
     In this state, the second mold  51  is inserted into the inside of the first mold  21  from the first opening  36  of the first mold  21 . The second mold  51  inserted inside the first mold  21  is continuously inserted in the direction of arrow D toward the first right side wall  34 . 
     As shown in  FIG. 18B , the front surface  53   a  formed on the second space block  53  of the second mold  51  contacts the rear surface  23   a  formed on the first space block  23  of the first mold  21 . In this state, the second mold  51  is kept in a state of being inserted inside the first mold  21 . 
     In this way, the first guide  112  is formed on the first mold  21 , and the second guide  113  is formed on the second mold  51 . As a result, the second mold  51  can be smoothly inserted into the first mold  21  by fitting (locking) the second guide  113  to the first guide  112 . That is, the second connector  12  can be smoothly inserted into and coupled with the first connector  11 . 
     Further, as described from the first embodiment to the third embodiment, just by changing the shapes of the first guides  22 ,  112  and the second guides  52 ,  102 ,  113 , it is possible to insert the second connector  12  into the first connector  11  from various directions such as the X (left and right) direction, Y (front and back) direction, and Z (up and down) direction to be coupled therewith. 
     As a result, for example, by inserting the second connector  12  into the first connector  11  from the X (left and right) direction, it is possible to enable connection with a printed wiring board installed on a surface different from the direction of installation (insertion) into the device or a printed wiring board. 
     For example, when installing a printed wiring board from the front of the device, a printed wiring board having a connection connector at the interior rear of the device is usually provided. On the other hand, according to the contactor rotary connectors  10 ,  100 ,  110  of the first to third embodiments, installation is possible at any location on the right, left, top or bottom of the interior of the device with respect to the positional relationship with the installation (insertion) direction of the printed wiring board. 
     Fourth Embodiment 
     In the contactor rotary connector  120  as shown in  FIGS. 19A and 19B , the standard contactor  56  of the first embodiment is replaced with a contactor  122 . Further, the contact rotary connector  120  is one in which the first contact pin  24  and the second contact pin  54  of the first embodiment are respectively changed to a first card edge (edge connector, first terminal)  125  and a second card edge (edge connector, second terminal)  126 . 
     The contactor  122  is provided with a conductor  123  formed in a convex shape. By forming the conductor  123  in a convex shape, the conductor  123  of the contactor  122  can be brought into contact with the first card edge  125  and the second card edge  126 . 
     Further, the precharge contactor  57  of the first embodiment can also be made a contactor provided with a convex conductor like the contactor  122 . Thereby it is possible to expand the applications of the contactor rotary connector. 
     Fifth Embodiment 
     As shown in  FIGS. 20A and 20B , the contactor rotary connector  130  is one in which the standard contactor  56  of the first embodiment is replaced with the contactor  132 . Further, the contactor rotary connector  130  is one in which the second contact pin  54  of the first embodiment is replaced with a second card edge (edge connector, second terminal)  126 . 
     The contactor  132  is provided with a conductor  133  in which a portion  133   a  is formed in a convex shape. Specifically, the conductor  133  has a part  133   b  formed in a groove shape similarly to the first embodiment and a portion  133   a  formed in a convex shape. Therefore, the conductor  133  of the contactor  132  can be brought into contact with the first contact pin  24  and the second card edge  126 . 
     Further, the precharge contactor  57  of the first embodiment can be made a contactor provided with a groove-shaped part and a convex part in the conductor, similarly to the contactor  132 . This makes it possible to expand the applications of the contactor rotary connector. 
     Sixth Embodiment of Minimum Configuration of Contactor Rotary Connector  10   
     A sixth embodiment of the minimum configuration of the contactor rotary connector  10  will be described with reference to  FIG. 21 . 
     The contactor rotary connector  10  is provided with a first connector  11  in which the first terminal  24  is supported by the first mold  21 , and a second connector  12  in which the second terminal  54  is supported by the second mold  51 . 
     The first connector  11  is provided with a first space block  23 . The first space block  23  is provided in the first mold  21 . 
     The second connector  12  is provided with a second space block  53 , a fixed component  55 , contactors  56  and  57 , and a rotating shaft  58 . 
     The second space block  53  is provided in the second mold  51 . 
     The fixed component  55  is rotatably housed in the first space block  23  and the second space block  53  in a state of the second mold  51  being coupled to (inserted in) the first mold  21 . As a result, the first mold  21  and the second mold  51  are held in a coupled state. 
     The contactors  56  and  57  are formed so as to be capable of making contact with the first contact pin  24  and the second contact pin  54 . 
     The rotating shaft  58  integrally couples the contactors  56 ,  57  and the fixed component  55 , and is rotatably supported by one of the first mold  21  and the second mold  51 . By rotating the rotating shaft  58  to rotate the contactors  56  and  57 , the first contact pin  24  and the second contact pin  54  are connected (brought into electrical conduction) by the contactors  56  and  57 . 
     Therefore, by rotatably housing the fixed component  55  in the first space block  23  and the second space block  53 , the first mold  21  and the second mold  51  can be held in the coupled state. Here, by rotating the fixed component  55  on the rotating shaft  58 , it is possible to prevent the occurrence of misalignment or slip off between the first space block  23  and the second space block  53 . 
     In other words, by rotating the fixed component  55  in the first space block  23  and the second space block  53 , it is possible to prevent the occurrence of misalignment or slip off between the first mold  21  and the second mold  51 . Therefore, the first mold  21  and the second mold  51  can be accurately held in a coupled state. As a result, the contactors  56  and  57  can be brought into stable contact (connection) with the first terminal  24  and the second terminal  54 . 
     While embodiments of the present invention have been described above, these embodiments have been presented by way of examples and are not intended to limit the scope of the invention. This embodiments can be embodied in a variety of other configurations, and various omissions, substitutions, and changes can be made without departing from the gist of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, as well as in the scope of the invention described in the claims and the equivalent scope thereof. 
     For example, in the above-described embodiments, an example was described in which the standard base  71  of the standard contactor  56  and the precharge base  76  of the precharge contactor  57  are formed in a substantially triangular shape (fan shape), but the present invention is not limited thereto. As another example, for example, the standard contactor  56  and the precharge contactor  57  need only have shapes capable of supporting the standard conductor  72  and the precharge conductor  77 . 
     Further, the arrangement of the standard contactor  56  and the precharge contactor  57  described in the above embodiments can be arbitrarily changed. 
     Moreover, in the above-described embodiments, an example in which the rotating shaft  58  is rotatably supported by the second mold  51  has been described. However, as another example, the rotating shaft  58  may be rotatably supported by the first mold  21 .
