     SUMMARY OF INVENTION 
     Technical Problem 
     However, in a connector disclosed in Patent Literature 1, an object-side connector coupled to a cable-side connector might be removed from the object. For example, when an object-side connector is suddenly decoupled from an electric circuit inside the object while power is supplied, a spark or a shorting might occur, which disadvantageously may cause damage to the electric circuit. 
     In view of such problem, an object of the present invention is to provide a connector that can prevent damage to an electric circuit provided inside a connecting object. 
     Solution to Problem 
     To solve the aforementioned problem, a connector according to the present invention includes a cable-side connector that supports a cable and a terminal part secured to a distal end of the cable, and an object-side connector provided on a connecting object and coupled to the cable-side connector. The object-side connector includes an object-side securing portion which is secured to the connecting object. The object-side securing portion is secured to the connecting object with a detachable fastening member. The cable-side connector includes an opposing portion that opposes the object-side securing portion in a fastening direction of the fastening member. 
     According to the present invention, the object-side securing portion for securing the object-side connector to the connecting object and the opposing portion provided on the cable-side connector oppose each other in the fastening direction of the fastening member, so that the object-side securing portion cannot be removed when the cable-side connector and the object-side connector are coupled because a tool for removing the fastening member interferes with the opposing portion. By disallowing removal of the object-side connector from the connecting object when the cable-side connector and the object-side connector are coupled, damage to an electric circuit provided inside the connecting object can be prevented. 
     Preferably, according to the embodiment, the cable-side connector further includes a housing that supports the cable and the terminal part and a supporting member that supports the cable and the housing, the supporting member includes a first supporting member and a second supporting member and supports the cable and the housing between the first supporting member and the second supporting member, and the opposing portion includes a first opposing portion integrally provided on the first supporting member, a second opposing portion integrally provided on the second supporting member, and a securing member that secures together the first opposing portion and the second opposing portion to secure together the first supporting member and the second supporting member. 
     In such a configuration in which the opposing portion is positioned to oppose the object-side securing portion in the connecting direction, the first opposing portion integrated with the first supporting part, and the second opposing portion integrated with the second supporting part are included, the opposing portion has a function of securing the first supporting part and the second supporting part as well as a function of disallowing removal of the object-side securing portion when the cable-side connector and the object-side connector are coupled, so that the structure can be made simple without providing any additional member. 
     Preferably, according to the present invention, the cable-side connector further includes a cable-side securing portion secured to the connecting object with another detachable fastening member, and the cable-side securing portion does not overlap with the opposing portion when viewed in a fastening direction of the other fastening member. 
     In such a configuration in which the cable-side connector includes the cable-side securing portion that is secured to the connecting object with the other detachable fastening member, the cable-side connector can surely be secured to the connecting object, thereby preventing decoupling of the cable-side connector and the object-side connector by vibration or the like. Furthermore, since the cable-side securing portion is provided so as not to overlap with the opposing portion when viewed in the fastening direction of the other fastening member, unfastening of the cable-side securing portion from the connecting object can easily be recognized when removing the cable-side connector, which thereby prevents accidental removal of the object-side securing portion. That is, since the cable-side securing portion is not overlapping with the opposing portion in the fastening direction of the other fastening member but the object-side securing portion is overlapping with the opposing portion in the fastening direction of the fastening member, only the other fastening member securing the cable-side securing portion can be removed. Thus the sequential procedure of removing the connector can be determined. 
     Preferably, according to the present invention, the cable-side connector further includes a housing that supports the cable and the terminal part, a supporting member that supports the cable and the housing, and a cable-side securing portion that is secured to the connecting object with the other detachable fastening member, the supporting member includes a first supporting member and a second supporting member and supports the cable and the housing between the first supporting member and the second supporting member, the opposing portion is integrally provided on the first supporting member, and the cable-side securing portion is integrally provided on the first supporting member and does not overlap with the opposing portion when viewed in a fastening direction of the other fastening member. 
     In such a configuration, the opposing portion and the cable-side securing portion are integrally provided on the first supporting member. Thus, even when the second supporting member is removed, the first supporting member is secured to the connecting object to keep the cable-side connector coupled to the object-side connector and to disallow removal of the object-side securing portion by causing interference between a tool for removing the fastening member and the opposing portion. 
     Preferably, according to the present invention, the electric-side connector includes a supporting member securing portion integrally provided on the second supporting member, and the first supporting member and the second supporting member are secured together by a securing member that secures the opposing portion and the supporting member securing portion. 
     In such a configuration, the opposing portion is integrally provided on the first supporting member, the supporting member securing portion integrated with the second supporting member is provided on the second supporting member, and the first supporting member and the second supporting member are secured together with the securing member that secures together the opposing portion and the supporting member securing portion. Thus, the opposing portion has a function of securing together the first supporting part and the second supporting part as well as a function of disallowing removal of the object-side securing portion when the cable-side connector and the object-side connector are coupled, so that the structure can be made simple without providing any additional member. 
     Advantageous Effects of Invention 
     As described above, the connector according to the present invention is configured to disallow unfastening of the object-side securing portion when the cable-side connector and the object-side connector are coupled by causing interference of a tool with the opposing portion, thereby disallowing removal of the object-side connector from the connecting object. The damage to the electric circuit provided inside the connecting object can thus be prevented.

The body-side securing portion  311   a  and the cap-side securing portion  311   b  are respectively provided with insertion holes  312   a  and  312   b  in each of which the bolt  31   c  can be inserted. The insertion hole  312   a  provided in the body-side securing portion  311   a  has a tapped thread. The insertion hole  312   b  provided in the cap-side securing portion  311   b  penetrates the cap-side securing portion  311   b  and allows the bolt  31   c  to be inserted therein in the direction indicated by the arrow Z in the figure. 
     As illustrated in  FIGS. 2 and 3 , the shell body  31   a  includes a main body  310 , a cable-side securing portion  313  used for securing the shell body  31   a  to the unit case U with the detachable bolt  51 , a cutout  314  having a shape tracing the profile of a device-side securing portion  43 , which will be described later, a receiver groove  315  for receiving a protruding portion  317  of the shell cap member  31   b , which will be described later, and a rib  316  provided upright on the inner circumferential surface of the shell body  31   a  to protrude toward the shell cap member  31   b  and extend in the connecting direction X inside the first accommodating portion  3   a.    
     The main body  310  includes a cylindrical portion  310   a  having an approximately cylindrical shape with the inner profile tracing the outer shape of the female housing  32 , and a half-cylindrical portion  310   b  continuing from the lower part of the cylindrical portion  310   a  to extend in the connecting direction X toward the cable side. The cable-side securing portion  313  protrudes along the unit case U in the Y direction from the side face in the second side in the Y direction (upper left side in  FIG. 1 ) on the end portion of the cylindrical portion  310   a  in the device side in the connecting direction X. That is, the cable-side securing portion  313  is provided so as not to overlap with the shell securing portion  311  when viewed in the fastening direction of the bolt  51 . 
     The cutout  314  is provided in a side face in the first side in the Y direction on the end portion of the cylindrical portion  310   a  in the device side in the connecting direction X. The receiver groove  315  is provided in a portion at the end of the cylindrical portion  310   a  in the cable side in the connecting direction X where the shell cap member  31   b  comes. The rib  316  is provided upright on the inner face of the cylindrical portion  310   a  in the lower side in the Z direction. The body-side securing portion  311   a  is integrally provided on the shell body  31   a  to protrude in the Y direction from a side face of the half-cylindrical portion  310   b  in the first side in the Y direction. 
     As illustrated in  FIG. 3 , the shell cap member  31   b  further includes a cap main body  320  having an approximately half cylindrical shape placed on the half-cylindrical portion  310   b  of the shell body  31   a , a protruding portion  317  continuing from an approximate center along the Y direction of the end portion of the cap main body  320  in the device side along the connecting direction X to extend in the connecting direction X toward the device side, and an engagement portion  318  provided on the protruding portion  317  to extend in the Z direction from the first accommodating portion  3   a  toward the shell body  31   a . The cap main body  320  is shaped so as to form a face continuing from the face of the cylindrical portion  310   a  in the upper Z direction side when the cap main body  320  is placed on and attached to the half-cylindrical portion  310   b  of the shell body  31   a  from the upper Z direction. When the shell cap member  31   b  is attached to the shell body  31   a , the engagement portion  318  is inserted in a recess  325 , which will be described later, of the female housing  32  to make contact with a wall  326  from the device side. The cap-side securing portion  311   b  is integrally provided on the shell cap member  31   b  so as to protrude in the Y direction from the side face of the cap main body  320  in the first side in the Y direction when the shell cap member  31   b  is placed on the shell body  31   a.    
     As illustrated in  FIGS. 2 and 3 , the female housing  32  includes a coupling portion  321  having an approximately rectangular solid shape of which external profile traces the profile of the first accommodating portion  3   a  of the shield shell  31  and provided in the device side in the connecting direction X to receive and make connection with the male terminal  41  of the device-side connector  4 , a cable lead-out portion  322  through which the shield cable  2  is led out from the cable side in the connecting direction X, and an outer peripheral portion  323  extending in the connecting direction X from the coupling portion  321  to the cable lead-out portion  322  and having four faces. 
     Among four faces of the outer peripheral portion  323 , an outer peripheral portion  323   a  makes contact with the face of the shell body  31   a  on which the rib  316  is provided. The outer peripheral portion  323   a  is provided with a groove  324  extending along the connecting direction X to the end of the cable side to receive the rib  316  of the shell body  31   a  to the end of the cable side. An outer peripheral portion  323   b  provided to the outer peripheral portion  323  in the opposite side of the outer peripheral portion  323   a . The shield cable  2  inserted in the female housing  32  is disposed between the outer peripheral portions  323   a  and  323   b . The outer peripheral portion  323   b  is provided with a recess  325  and a wall  326 . The recess  325  is provided in the same location in the Y direction as the groove  324  and extends along the connecting direction X. The engagement portion  318  of the shell cap member  31   b  can be inserted in the recess  325 . The wall  326  is provided to plug the end of the recess  325  in the cable side. 
     The device-side connector  4  includes a male housing  40  formed of an insulating resin including a device-side main body  44  and a device-side securing portion  43  in an integrated manner. The device-side main body  44  is provided with an insertion portion  42  in which the male terminal  41  is inserted. The device-side securing portion  43  (corresponding to the “object-side securing portion” in the claims) is secured to the unit case U. The Dimension and shape of the male housing  40  in the cable side in the connecting direction X trace the inner form of the cylindrical portion  310   a  of the shield shell  31 . The Dimension and shape of the male housing  40  in the device side X in the connecting direction X trace the shape of an opening U 1 , which will be described later, of the unit case U. 
     As illustrated in  FIGS. 1, 2, and 4 , the device-side securing portion  43  is provided to protrude along the unit case U in the Y direction from the side face of the device-side main body  44  in the first side in the Y direction. The shield connector  1  includes the body-side securing portion  311   a  and the cap-side securing portion  311   b  respectively provided on the shell body  31   a  and the shell cap member  31   b  in an integrated manner and a device-side securing hole  431  in which the bolt  52  for securing the device-side connector  4  to the unit case U is inserted from the cable side in the connecting direction X. The device-side securing hole  431  is positioned so as to oppose the body-side securing portion  311   a  and the cap-side securing portion  311   b  in the connecting direction X. In other words, the body-side securing portion  311   a  and the cap-side securing portion  311   b  are positioned to oppose the device-side securing portion  43  in the fastening direction of the bolt  52 . Thus as illustrated in  FIG. 5 , the tool T for removing the bolt  52  interferes with the body-side securing portion  311   a  and the cap-side securing portion  311   b  when the shield connector  1  is in the coupling state. The device-side securing portion  43  is secured to the unit case U by fastening the bolt  52 , thereby securing the device-side connector  4  to the unit case U. 
     The unit case U is a conductive chassis accommodating an electric device. The whole unit case U is electrically grounded. The unit case U is provided with the opening U 1  to which the device-side connector  4  is attached and tapped threads at locations corresponding to the cable-side securing portion  313  and the device-side securing portion  43 . 
     A method of assembling the cable-side connector  3 , and a method of coupling the cable-side connector  3  and the device-side connector  4  and securing the coupled cable-side connector  3  and the device-side connector  4  to the unit case U will exemplarily be described. 
     First, the packing  26 , the shield pipe  27 , the sealing member  28 , and the shield cable  2  to which the female terminal  25  is attached are inserted in the coupling portion  321  of the female housing  32 . The device-side connector  4  is inserted in the opening U 1  of the unit case U, the male terminal  41  of the electric device is inserted in the insertion portion  42 , and the device-side securing portion  43  is secured to the unit case U with the bolt  52 . The cable-side connector  3  is coupled to the device-side connector  4  in a manner that the cutout  314  of the shell body  31   a  mates the device-side securing portion  43  and the male housing  40  slides against the inner side of the shield shell  31 , so that the male terminal  41  is inserted in the female terminal  25  to be electrically connected thereto. The cable-side securing portion  313  is then secured to the unit case U with the bolt  51  to complete the coupling. In the final phase, with the rib  316  of the shell body  31   a  positioned in the groove  324  of the female housing  32 , the female housing  32  and the shield cable  2  are accommodated in the first accommodating portion  3   a  and the second accommodating portion  3   b  of the shell body  31   a . Then, as indicated in the arrow A in  FIG. 3 , the shell cap member  31   b  covers the female housing  32  in a manner that the engagement portion  318  of the shell cap member  31   b  is inserted in the recess  325  of the female housing  32 . The shell body  31   a  and the shell cap member  31   b  are secured together by securing the body-side securing portion  311   a  and the cap-side securing portion  311   b  with the bolt  31   c . In this manner, the shield cable  2  and the female housing  32  are held between the shell body  31   a  and the shell cap member  31   b.    
     The assembling procedure is not limited to the procedure described above. The order of the steps may suitably be changed as long as the device-side connector  4  is secured to the unit case U via the device-side securing portion  43  before the cable-side connector  3  and the device-side connector  4  are coupled. 
     Consequently, the shield shell  31  is in contact with the unit case U as well as with the shield pipe  27  by the inner face of the second accommodating portion  3   b  of the shield shell  31 . With the shield pipe  27  electrically connected to the shield  23 , the unit case U, the shield shell  31 , the shield pipe  27 , and the shield  23  are in equipotential state, namely, at ground potential. Thus the unit case U, the first accommodating portion  3   a , the second accommodating portion  3   b , and the conductor  21  are shielded, preventing electromagnetic waves to leak outside or intruding from outside. 
     In the procedure of removing the shield connector  1 , the device-side connector  4  cannot be removed when the cable-side connector  3  and the device-side connector  4  are coupled because the tool T interferes with the body-side securing portion  311   a  and the cap-side securing portion  311   b  as illustrated in  FIGS. 4 and 5 . Therefore, the bolt  51  inserted in the cable-side securing portion  313  of the cable-side connector  3  is first removed to decouple the cable-side connector  3  and the device-side connector  4 , and then the bolt  52  inserted in the device-side securing portion  43  of the device-side connector  4  is removed. 
     According to the embodiment described above, the device-side securing portion  43  of the device-side connector  4  is provided in the position to oppose the shell securing portion  311  of the shield shell  31  in the fastening direction (connecting direction X) of the bolt  52  when assembling the connector, so that when the cable-side connector  3  and the device-side connector  4  are coupled, the tool T for removing the bolt  52  interferes with the shell securing portion  311 , disallowing the removal of the device-side connector  4 , as illustrated in  FIG. 5 . Thus the device-side connector  4  cannot be removed when the device-side connector  4  is coupled, thereby preventing damage to the electric circuit inside the electric device. 
     Moreover, the shell securing portion  311  of the shield shell  31  is provided in the position to oppose the device-side securing portion  43  in the connecting direction X and includes the body-side securing portion  311   a  integrally provided on the shell body  31   a  and the cap-side securing portion  311   b  integrally provided on the shell cap member  31   b , and the body-side securing portion  311   a  and the cap-side securing portion  311   b  are secured together with the bolt  31   c  to secure together the shell body  31   a  and the shell cap member  31   b . Thus the shell securing portion  311  has the function of securing together the shell body  31   a  and the shell cap member  31   b  and the function of disallowing removal of the device-side connector  4  when the cable-side connector  3  and the device-side connector  4  are coupled. Therefore the structure can be made simple without providing any additional member. 
     Moreover, since the shell body  31   a  of the cable-side connector  3  includes the cable-side securing portion  313  which is secured to the unit case U with the bolt  51 , the cable-side connector  3  is further surely secured to the unit case U, thereby preventing decoupling of the cable-side connector  3  and the device-side connector  4  by, for example, vibration. 
     Furthermore, since the cable-side securing portion  313  is provided so as not to overlap with the shell securing portion  311  when viewed in the fastening direction of the bolt  51 , unfastening of the cable-side securing portion  313  from the unit case U can easily be recognized when removing the cable-side connector  3 , which thereby prevents accidental removal of the device-side securing portion  43 . That is, since the cable-side securing portion  313  is not overlapping with the shell securing portion  311  in the fastening direction of the bolt  51  but the device-side securing portion  43  is overlapping with the shell securing portion  311  in the fastening direction of the bolt  52 , only the bolt  51  securing the cable-side securing portion  313  can be removed. Thus the sequential procedure of removing the shield connector  1  can be determined. 
     The scope of the present invention is not limited to the embodiment described above. Any other configuration that can achieve the object of the present invention, such as the modifications as will be described below, are included in the scope of the present invention. 
     For example, in the embodiment described above, the shell securing portion  311  is provided so as to oppose the device-side securing portion  43  in the fastening direction of the bolt  52 . Alternatively, it may be configured that the body-side securing portion  311   a  is provided so as to oppose the device-side securing portion  43  in the fastening direction of the bolt  52 , so that the tool T for removing the bolt  52  interferes with the body-side securing portion  311   a  even with the shell cap member  31   b  removed. The cable-side securing portion  313  is provided on the shell body  31   a  and the body-side securing portion  311   a  is provided so as to oppose the device-side securing portion  43  in the fastening direction of the bolt  52  for securing the device-side securing portion  43 . So that, even when the body-side securing portion  311   a  and the cap-side securing portion  311   b  are unfastened to remove the shell cap member  31   b , the shell body  31   a  is secured to the unit case U, keeping the cable-side connector  3  and the device-side connector  4  coupled together and disallowing the removal of the device-side securing portion  43  by causing interference between the tool T for removing the bolt  52  and the body-side securing portion  311   a . In such a configuration, the body-side securing portion  311   a  corresponds to the “opposing portion” in the claims and the cap-side securing portion  311   b  corresponds to the “supporting member securing portion” in the claims. 
     In the embodiment, the shell securing portion  311  is provided in a position to oppose the device-side securing portion  43  in the fastening direction of the bolt  52  (connecting direction X) to cause interference with the tool T. Alternatively, for example, as long as a member (opposing portion) is provided at the same location to cause interference with the tool T, the shell securing portion  311  may be provided at a position other than the position of the opposing portion. 
     In the embodiment, the body-side securing portion  311   a  and the cap-side securing portion  311   b  are respectively provided on the main body  310  and the cap main body  320  of the cable-side connector  3  in an integrated manner to serve as the opposing portions. Alternatively, the main body  310  and the cap main body  320  themselves may be configured to serve as the opposing portion. That is, the main body  310  and the cap main body  320  may be formed so as to oppose the device-side securing portion  43  in the fastening direction of the bolt  52  to interfere with the tool T for removing the bolt  52 . 
     Moreover, the device-side connector  4  may be secured to the unit case U with a plurality of device-side securing portions  43 . In such a case, the opposing portion may be provided to each of a plurality of device-side securing portions  43 . Some or all of a plurality of opposing portions may serve as the shell securing portion  311 , or alternatively, the shell securing portion  311  may be provided at a location different from the opposing portion. 
     In the embodiment, the device-side securing portion  43  is provided to protrude in the Y direction along the unit case U from the side face of the device-side main body  44  in the first side in the Y direction. Alternatively, the device-side securing portion  43  may be provided along a direction other than the Y direction as long as the device-side securing portion  43  is secured onto the unit case U along the unit case U in a manner that the tool T for removing the bolt  52  for securing the device-side securing portion  43  interferes with the shell securing portion  311 . When the device-side securing portion  43  is provided along a direction different from the direction described in the embodiment, the shell securing portion  311  is provided in the position corresponding to the device-side securing portion  43 . 
     In the embodiment, the shield cable  2  composed of a coaxial cable is exemplarily described as the cable. Alternatively, the present invention can be applied to a connector using a cable other than the shield cable. In such a case, a member that provides shield for a connector can be omitted, and the shell body  31   a  and the shell cap member  31   b  may be formed of a material with no conductivity, such as a resin.
