     DESCRIPTION OF THE EMBODIMENTS 
     A connection part having an exposed conductive wire inside a connector of an electronic apparatus is particularly preferred to be waterproof because entering of liquid such as water from the outside may cause problems such as a short. 
     The objective of the present invention is to provide a connector having a property of preventing entering of liquid into a connection part inside the connector. 
     In the following, configurations of the present invention will be described in detail along with embodiments with reference to  FIG. 1  through  FIG. 9B . 
     [First Embodiment] 
     A connector (connector  10 ) according to the first embodiment includes a housing (housing  1 ) having a guide part (guide part  4 ) to which a male terminal (male terminal  20 ) is inserted, a connection part (connection part  2   a,    2   b ) exposed on the guide part so as to make contact with a terminal member (terminal member  21 ) of the male terminal in a state where the male terminal is inserted, a cover member (cover member  6 ) provided on the guide part so as to cover the connection part, while making contact with the connection part, in a state where the male terminal is not inserted, and an elastic member (spring  7 ) configured to urge the cover member toward an opening (opening  5 ) of the guide part in the state where the male terminal is not inserted. The cover member is moved, upon inserting the male terminal, to a side of the guide part opposite to the opening so as not to cover the connection part. Here, examples of application along with reference signs in the embodiment are noted in brackets. 
     The connector  10  according to the first embodiment will be described, taking a mini jack which connects to a mini plug as an example. First, with reference to  FIG. 1 , basic configurations of the connector  10  which is a female terminal and the male terminal (plug)  20  will be described. 
       FIG. 1  is a cross-sectional view illustrating the basic configuration of the connector  10  according to the first embodiment, in a state where the male terminal  20  is not inserted to a guide part  4  which accommodates a terminal inside the connector  10 . 
     The housing  1 , which is an external part of the connector  10  illustrated in  FIG. 1 , forms the guide part  4  to which the male terminal  20  is inserted. The guide part  4  is provided with connection parts  2  ( 2   a  and  2   b ), where conductive wires  3  ( 3   a  and  3   b ) are exposed so as to be connected by an electronic apparatus. 
     A terminal member  21  of the male terminal  20  to be connected to the connector  10  is inserted to the guide part  4  through an opening  5  of the guide part  4 , so that the terminal member  21  makes contact with the connection parts  2  inside the connector  10  for electric conduction. 
     As the connection parts  2  of the connector  10  illustrated in  FIG. 1  are not waterproof, liquid may enter into the guide part  4  in the state where the male terminal  20  is not inserted, which may cause the connection parts  2  to short and may make the connector  10  or an electronic apparatus having the connector  10  become out of order. 
     Therefore, the guide part  4  of the connector  10  according to the first embodiment is provided with a slidable cover member  6 .  FIG. 2  is a cross-sectional view illustrating the connector  10  according to the first embodiment, in the state where the male terminal  20  is not inserted to the guide part  4  which accommodates a terminal inside the connector  10 . Further,  FIG. 3  is a schematic diagram of the connector  10  illustrated in  FIG. 2  viewed from the opening  5 . 
     As illustrated in  FIG. 2 , the cover member  6  is disposed on a position of the guide part  4  so as to cover at least the connection parts  2   a  and  2   b.  Further, the cover member  6  is supported by a spring  7 , which is an elastic member, against the side of the guide part  4  opposite to the opening  5 , so that the cover member  6  is urged towards the opening  5  by the spring  7 . Here, the elastic member is not limited to the spring  7  as illustrated in the drawing as far as the elastic member urges the cover member  6  towards the opening  5 . 
     Here, it is preferable that, in the state where the male terminal  20  is not inserted, the cover member  6  is positioned so that a surface of the cover member  6  and the external surface of the housing  1  make a flat surface as illustrated in  FIG. 2 . However, the cover member  6  may be positioned so as to be slightly inside the external surface or partially out of the external surface. 
     Further, as illustrated in  FIG. 3 , it is preferable that the shape of the cross-sectional surface of the cover member  6  has the same type of shape of the cross-sectional surface of the guide part  4  of the connector  10 , so that the cover member  6  makes no or small clearance with the internal wall of the guide part  4  in a state where the cover member  6  is set in the guide part  4 . 
     As described above, the cover member  6  of the connector  10  according to the first embodiment covers the opening  5  of the connector  10  and the connection parts  2  exposed on the guide part  4 , in the state where the male terminal  20  is not inserted, so as to prevent entering of liquid into the guide part  4  of the connector  10  and a short of the connection parts. 
       FIG. 4  is a cross-sectional view illustrating a state where the male terminal  20  is partially inserted to the guide part  4  of the connector  10 . Further,  FIG. 5  is a cross-sectional view illustrating a state where the male terminal  20  is inserted to the guide part  4  of the connector  10 . 
     When the terminal member  21  of the male terminal  20  is inserted to the guide part  4  of the connector  10  in the state illustrated in  FIG. 2 , the cover member  6  is pushed by the terminal member  21  and slid towards the bottom surface of the guide part  4  while the spring  7  is compressed, as illustrated in  FIG. 4 . 
     Then, when the terminal member  21  of the male terminal  20  is fully inserted, the cover member is further slid towards the bottom surface as illustrated in  FIG. 5 , so that the terminal member  21  makes contacts with the connection parts  2   a  and  2   b.  Here, the elastic force of the spring  7  is predetermined not to be so strong that the spring  7  pushes back the male terminal  20  in the state where the male terminal  20  is inserted. 
     Then, when the male terminal  20  is unplugged, the spring  7  pushes back the cover member  6  towards the opening  5  to return to the state as illustrated in  FIG. 2 . That is to say, the elastic force of the spring  7  is predetermined not to be so strong that the spring  7  pushes back the male terminal  20  in the state where the male terminal  20  is inserted, but predetermined to be strong enough to push back the cover member  6  in the state where the male terminal  20  is not inserted. 
     Furthermore, as illustrated in  FIG. 2 ,  FIG. 4 , and  FIG. 5 , it is preferable that the cover member  6  is provided with a seal member  8  (such as a packing) so as to seal the gap between the cover member  6  and the internal wall of the guide part  4 . The seal member  8  is provided on a position closer to the opening  5  than the positions of the connection parts  2  in the state where the male terminal  20  is not inserted so as to seal the gap between the cover member  6  and the internal wall of the guide part  4 . 
     The slidable cover member  6  of the connector  10  according to the first embodiment as described above covers the connection parts  2  disposed inside the connector  10  in the state where the male terminal  20  is not inserted, and therefore prevents a short of the connection parts  2 . Furthermore, as the cover member  6  has the shape that can be set in the guide part  4 , entering of liquid into the guide part  4  is prevented. Moreover, the seal member  8  disposed on the cover member  6  further effectively prevents entering of liquid into the connection parts  2 , so as to enhance the waterproof effect. 
     Furthermore, the connector  10  is provided with the slidable cover member  6  disposed inside the housing  1 , not provided with an exterior cover, so that the connector  10  can be connected with a male terminal without causing problems such as taking the cover off and putting the cover back on. Here, entering of liquid is securely prevented as a user cannot fail to forget to put the cover on. 
     Further, an electronic apparatus may be provided with the connector  10  according to the first embodiment so as to be waterproof on the connector part. The connector  10  is applicable to any electronic apparatuses, for example, an image capturing apparatus such as a digital camera, a portable electronic device such as a cellphone, a smartphone, and a tablet, an image forming apparatus such as a printer, an image projecting apparatus such as a projector, and an information processing apparatus such as a personal computer. Particularly, the connector  10  is preferably applied to portable electronic devices with high risk of getting wet such as a digital camera and a cellphone. 
     [Second Embodiment] 
     In the following, another embodiment of the connector  10  according to the present invention will be described. Here, elements having the same configurations as in the embodiment above are appropriately omitted. 
     In the above description of the first embodiment, the elastic force of the spring  7  is predetermined not to be so strong that the spring  7  pushes back the male terminal  20  in the state where the male terminal  20  is inserted to the connector  10 . Here, it is preferable that the connector  10  is provided with a structure (i.e. urging stopper) which prevents the spring  7  from pushing back the terminal member  21  and the cover member  6  in the state where the terminal member  21  of the male terminal  20  is fully inserted. 
     An urging stopper according to the second embodiment includes a pin member (lock pin  35 ) provided on the cover member  6 , and a lever member (lock lever  30 ) provided on the housing  1 . The pin member and the lever member stick out in the guide part  4  in the state where the male terminal  20  is inserted. The pin member and the lever member make contact with each other on surfaces orthogonal to a direction in which the spring  7  urges the cover member  6  and the terminal member  21  toward the opening  5 . 
     The connector  10  provided with the urging stopper will be described, with reference to  FIGS. 6A through 6C  and  FIG. 7 .  FIG. 6A  is a cross-sectional view illustrating a state where the terminal member  21  of the male terminal  20  is about to be inserted to the guide part  4  of the connector  10 . 
     As illustrated in  FIG. 6A , a U-shaped lock lever  30 , supported by a fulcrum point  33  so as to be swayable, is provided on a lower portion of the housing  1  of the connector  10 . A projecting part  31  of the lock lever  30  near the opening  5  is urged by a spring  34 , so as to make contact with the cover member  6  in the state where the male terminal  20  is not inserted. 
     A projecting part  32  of the lock lever  30  near the bottom of the guide part  4  has a greater degree of projection compared to the projecting part  31 , so that the projection tip sticks out into the guide part  4  in the state where the male terminal  20  is not inserted. Here, as illustrated, the housing  1  has openings so that the projecting parts  31  and  32  may stick out into the guide part  4  in accordance with sway of the lock lever  30 . 
     Furthermore, a lock pin  35  and a spring  36  which urges the lock pin  35  are provided on the cover member  6  near the end supported by the spring  7 . Moreover, a notch  37  is formed on the cover member  6 , so as to guide the projection tip of the projecting part  32 . 
       FIG. 6B  is a cross-sectional view illustrating the state where the terminal member  21  of the male terminal  20  is partially inserted to the guide part  4  of the connecter  10 . Further, the  FIG. 6C  is a cross-sectional view illustrating the state where the terminal member  21  of the male terminal  20  is fully inserted to the guide part  4  of the connecter  10 . 
     As illustrated in  FIG. 6B , when the cover member  6  is pushed in by the terminal member  21  of the male terminal  20 , the projecting part  32  is guided by the notch  37  formed on the cover member  6 . Then, the lock pin  35  provided on the cover member  6  is positioned on top of the projecting part  32  of the lock lever  30  while the spring  36  is compressed. Here, it is preferable that the projecting part  32  has an R-shape on the side facing the opening  5 , so that the lock pin  35  easily gets on top of the projecting part  32  when the terminal member  21  is inserted. Here, the projecting part  32  has a flat shape on the side facing the bottom of the guide part  4 . 
     Then, when the cover member  6  is further pushed in by the terminal member  21  of the male terminal  20  and the lock pin  35  gets over the projecting part  32 , the lock pin  35  is pushed by the spring  36  so as to stick back out into the notch  37  on a position beyond the projecting part  32  as illustrated in  FIG. 6C . 
     In the state described above, the surface of the lock pin  35  facing the opening  5  and the surface of the projecting part  32  facing the bottom of the guide part  4  are engaged. Here, the force of the spring  7  pushing the cover member  6  is restrained as the surface of the lock pin  35  facing the opening and the surface of the projecting part  32  facing the bottom of the guide part  4  touch each other. Therefore, it is prevented that the cover member  6  is pushed back toward the opening  5  and that the terminal member  21  of the male terminal  20  is pushed back when the terminal member  21  of the male terminal  20  is inserted. 
       FIG. 7  is a cross-sectional view illustrating a state where, after the male terminal  20  is inserted, the terminal member  21  of the male terminal  20  is unplugged from the connector  10 . When the terminal member  21  of the male terminal  20  is unplugged from the connector  10 , there is neither the cover member  6  nor the terminal member  21  on the position opposed by the projecting part  31  of the lock lever  30 , and therefore the lock lever  30  is swayed by the urging force of the spring  34  so that the projecting part  31  sticks out into the guide part  4 . 
     Here, the engagement of the lock pin  35  and the projecting part  32  is released as the projecting part  32  of the lock lever  30  moves downward, and therefore the cover member  6  is pushed back by the urging force of the spring  7  to the original position as illustrated in  FIG. 6A . 
     The connector  10  provided with such an urging stopper as described above can prevent the male terminal  20  from unintentionally being unplugged. Furthermore, adjusting and selecting the spring  7  is easy here because greater elastic force of the spring  7  may be applied. Here, the urging stopper as illustrated in  FIGS. 6A through 6C  and  FIG. 7  is just an example and the urging stopper is not limited to the example as far as the urging stopper has a configuration for preventing the male terminal  20  from being pushed back by the cover member  6  in the state where the male terminal  20  is inserted. 
     [Third Embodiment] 
     In the following, another embodiment of the connector  10  according to the present invention will be described. Here, elements having the same configurations as in the embodiments above are appropriately omitted. 
     The housing  1  of the connector  10  according to the third embodiment is provided with a seal member  9  on the internal wall of the guide part  4  so as to seal the gap between the terminal member  21  of the male terminal  20  inserted to the guide part  4  and the internal wall of the guide part  4 . The seal member  9  prevents, in the state where the male terminal  20  is inserted to the connector  10 , entering of liquid such as water through the gap between the terminal member  21  of the inserted male terminal  20  and the internal wall of the guide part  4  of the connector  10  and prevents a short of the connection parts  2 . 
       FIG. 8  is a cross-sectional view illustrating an example of the connector  10  according to the third embodiment. 
     As illustrated in  FIG. 8 , the housing  1  of the connector  10  is provided with the seal member  9  on the internal wall of the guide part  4  on a position closer to the opening  5  than the positions of the connection parts  2   a  and  2   b.  The seal member  9  seals the gap between the internal wall of the guide part  4  and the external surface of the male terminal  20  in the state where the male terminal  20  is inserted to the connector  10 . 
     The seal member  9  provides a secure waterproof property in the state where the male terminal  20  is inserted to the guide part  4  of the connector  10 , so as to prevent problems that occur due to entering of liquid into the connector  10 , such as a short. 
     The seal member  9  of the connector  10  according to the third embodiment as described above seals the gap between the terminal member  21  of the male terminal  20  and the internal wall of the guide part  4 , so as to improve the waterproof property of the connector  10  in the state where the male terminal  20  is inserted. 
     Here, the connector  10  may be provided with both the seal member  8  on the cover member  6  and the seal member  9  on the housing  1  as illustrated in the drawing relating to the third embodiment, but may also be provided with either one of the seal member  8  or the seal member  9 . The seal member  8  provided on the cover member  6  improves the waterproof property in the state where the male terminal  20  is not inserted. The seal member  9  provided on the housing  1  improves the waterproof property not only in the state where the male terminal  20  is not inserted but also in the state where the male terminal  20  is inserted. Providing both the seal member  8  and the seal member  9  further improves the waterproof property of the connector  10  and prevents entering of liquid into the guide part  4  more securely in the states where the male terminal  20  is and is not inserted. 
     [Fourth Embodiment] 
     In the following, another embodiment of the connector  10  according to the present invention will be described. Here, elements having the same configurations as in the embodiments above are appropriately omitted. 
       FIG. 9A  is a cross-sectional view illustrating a connector  50  according to the fourth embodiment, in a state where a male terminal  60  is not inserted.  FIG. 9B  is a cross-sectional view illustrating the connector  50  according to the fourth embodiment, in a state where the male terminal  60  is inserted. 
     As illustrated in  FIGS. 9A and 9B , the connector  50  according to the fourth embodiment is provided with the housing  1  having a shape of a hollow quadrangular prism, the conductive wire  3 , the cover member  6 , and the spring  7 . A terminal member  61  of the male terminal  60  such as a USB is inserted to the connector  50 . 
     The housing  1  forms the guide part  4  to which the terminal member  61  of the male terminal  60  is inserted, the opening  5  of the guide part  4 , and a prominent part  11  in a shape of a flat plate which sticks out from the side of the guide part  4  opposite to the opening  5  toward the opening  5 . 
     The conductive wire  3  is disposed along the prominent part  11  on the guide part of the connector  50 , so that the connection parts  2 , with which the terminal member  61  of the male terminal  60  makes contact, is provided on the surface of the prominent part  11 . 
     The cover member  6 , having a cross-sectional shape which is set in the guide part  4 , is disposed on the guide part  4  so as to be slidable along the prominent part  11  in a way of sliding the circumference of the prominent part  11  or the sides of the prominent part  11 . The cover member  6  is urged by the spring  7 , which is provided on the end of the guide part  4  opposite to the opening  5 , toward the opening  5 . The cover member  6  is urged by the spring  7  so that, in the state where the male terminal  60  is not inserted, the end the cover member  6  facing the opening  5  is on a position closer to the opening  5  than the position of the connection part  2 . 
     The cover member  6  is provided with a seal member  12  on a position closer to the opening  5  than the position of the connection part  2  in the state where the male terminal  60  is not inserted, so as to seal the gap with the prominent part  11 . The seal member  12  seals the gap between the internal surface of the cover member  6  and the external surface of the prominent part  11  formed by the housing  1 , so as to prevent entering of liquid into the connection part  2  in the state where the male terminal  60  is not inserted. 
     Furthermore, the cover member  6  is provided with a seal member  13  on the external surface, so as to seal the gap between the external surface of the cover member  6  and the internal surface of the guide part  4 . The seal member  13  prevents entering of liquid into the housing  1  through the gap between the external surface of the cover member  6  and the internal surface of the guide part  4 . 
     As illustrated in  FIG. 9A , in the state where the male terminal  60  is not inserted to the connector  50 , the cover member  6  is pushed by the spring  7  and positioned close to the opening  5 . In the state described above, the seal member  12  provided on the internal surface of the cover member  6  seals the gap between the internal surface of the cover member  6  and the external surface of the prominent part  11  formed by the housing  1 . Similarly, the seal member  13  seals the gap between the external surface of the cover member  6  and the internal surface of the guide part  4 . Here, the seal members  12  and  13  prevent entering of liquid into the connection part  2 . 
     As described in  FIG. 9B , in the state where the male terminal  60  is inserted to the connector  50 , the cover member  6  is pushed by the terminal member  61  of the male terminal  60  and positioned on the side of the guide part  4  opposite to the opening  5  while the spring  7  is compressed. In the state where the cover member  6  is pushed toward the side of the guide part  4  opposite to the opening  5 , the connection part  2  is exposed on the guide part  4  out of the cover member  6 , so that the connection part  2  and the terminal member  61  of the male terminal  60  make contact with each other. 
     The seal member  12  of the connector  50  according to the fourth embodiment as described above seals the gap between the internal surface of the cover member  6  and the external surface of the prominent part  11  in the state where the male terminal  60  is inserted to the connector  50 . Furthermore, the seal member  13  seals the gap between the external surface of the cover member  6  and the internal surface of the housing  1 . According to such a configuration, entering of liquid into the connection part  2  is prevented and the waterproof property is improved. 
     Here, another seal member may be provided on the internal surface of the guide part  4  formed by the housing  1  of the connector  50  so as to seal the gap between the internal surface of the guide part  4  formed by the housing  1  and the terminal member  61  of the male terminal  60  in the state where the male terminal  60  is inserted. According to such a configuration, entering of liquid into the guide part  4  of the connector  50  is further prevented and the waterproof property is further improved. 
     Further, the urging stopper exemplified in the second embodiment may be provided on the connector  10  according to the third embodiment or the connector  50  according to the fourth embodiment described above. Such an urging stopper prevents the male terminal  20  or the male terminal  60  inserted to the connector  10  or the connector  50  from unintentionally being unplugged. Here, the urging stopper provided on the connector  10  or the connector  50  is not limited to the example described in the second embodiment, as far as the urging stopper is capable of keeping the spring  7  compressed and keeping the cover member  6  pushed in the guide part  4 . 
     Further, although the embodiments described above are preferable examples for implementation, the present invention is not limited to the above embodiments and various variations may be made without departing from the scope of the present invention. 
     For example, although a configuration in which the external surface of a male terminal makes contact with connection parts disposed in a connector is described in the first through the third embodiments, taking examples of a mini plug as the male terminal and a mini jack as the connector, the present invention is applicable to a configuration in which the a terminal member is disposed inside a plug such as a USB plug corresponding to a USB connector as illustrated in the fourth embodiment. Further, the standard for terminals to be connected is not specifically limited, and therefore the present invention is duly applicable to connectors with other standards such as a connector for local area network (LAN) cable and a connector for the Institute of Electrical and Electronics Engineers (IEEE) 1394. 
     Although the connector is described above along with embodiments, the present invention is not limited to the above embodiments and various variations and modifications may be made without departing from the scope of the present invention as claimed. 
     According to the present invention, a short of a connection part caused by entering of liquid into the connection part inside the connector is prevented.
