The free ends 17b and 18b of the first lid 17 and the second lid 18 are set so as to be adjacent to each other, for example, at a closed position where the opening 11h is closed.

  Moreover, the 1st cover body 17 and the 2nd cover body 18 comprise what is called an inner opening lid | cover. That is, the first lid body 17 and the second lid body 18 move in the direction of opening the opening 11 h by movement (rotation) toward the inside of the housing 7.

  The first lid 17 and the second lid 18 are, for example, formed in a rectangular flat plate shape. The first lid body 17 and the second lid body 18 have conductivity on at least the outer surface of the housing 7. For example, the first lid body 17 and the second lid body 18 are made of sheet metal, and the whole has conductivity. In addition, for example, the first lid body 17 and the second lid body 18 are formed by applying a conductive paint to resin and forming a conductive layer on the surface.

  The first lid body 17 and the second lid body 18 are connected to the ground. The ground is, for example, a reference potential of the electronic circuit 9. The first lid body 17 and the second lid body 18 are, for example, such that shaft members 23 and 24 for pivotally supporting them with respect to the base surface 11 are connected to the reference potential of the electronic circuit 9 via a conductive wire or the like.

  The connector insertion port 1 is configured so that the second lid 18 and the second link member 26 are moved around the fifth rotation axis R5 in directions indicated by arrows y1 and y2 (in the closed position, the second lid 18 and the second link member). The second torsion spring 32 is biased in a direction in which it is further bent. The second torsion spring 32 urges the second lid 18 and the second link member 26 with a tightening force. The second torsion spring 32 may be constituted by a torsion spring that urges the second lid 18 and the second link member 26 in the directions indicated by the arrows y1 and y2 by a rewinding force.

  Similarly, the connector insertion port 1 connects the first lid 17 and the first link member 25 around the third rotation axis R3 at the closed position with the first lid 17 and the first link member 25. It has the 1st torsion spring 31 (refer FIG.4 (b)) urged | biased in the direction to be bent more. Similarly to the second torsion spring 32, the first torsion spring 31 may be biased by a rewinding force or may be biased by a winding force.

  FIG. 4 is a diagram for explaining the operation of the connector insertion slot 1. 4 is a plan view seen from the upper side of FIG. For ease of illustration, the first torsion spring 31 and the second torsion spring 32 are illustrated only in FIG. 4B.

  In FIG. 4A, the first lid 17 and the second lid 18 are in the closed position, and the opening 11h is closed. At this time, the first lid 17 and the first link member 25 are in a bent state. Similarly, the second lid 18 and the second link member 26 are bent. The connector receiving portion 13 is located at the initial position P0.

  In this state, when the insertion of the connector insertion portion 15 into the opening 11 h is started, the connector insertion portion 15 first comes into contact with the first lid body 17 and the second lid body 18. At this time, if the cable 5 is charged, the charged static electricity flows to the ground via the first lid 17 and the second lid 18.

  When the connector insertion portion 15 is further inserted, the first lid 17 and the second lid 18 are pushed by the connector insertion portion 15 as shown in FIG. Rotates from the outside to the inside around the two rotation axis R2. At this time, the first lid body 17 and the first link member 25 transition from the bent state to the linear state. Similarly, the second lid 18 and the second link member 26 transition from the bent state to the linear state. The connector receiving portion 13 moves from the initial position P0 to the inside.

  When the connector insertion portion 15 is further inserted from the state of FIG. 4B, the first lid 17 and the second lid 18 are further moved by the connector insertion portion 15 as shown in FIG. Pushed open. At this time, the first lid body 17 and the first link member 25 transition from the straight state to the bent state. Similarly, the second lid 18 and the second link member 26 transition from a straight state to a bent state. The connector receiving portion 13 moves from the position shown in FIG.

  When the first lid body 17 and the second lid body 18 reach the open position shown in FIG. 4C and the connector receiving portion 13 returns to the initial position P0, the connector insertion portion 15 is connected to the connector receiving portion 13. Connected.

The operation returns to the state shown in FIG.

  According to the first embodiment described above, when the connector insertion portion 15 is inserted into the opening 11h, the first lid 17 and the second lid are inserted before the connector insertion portion 15 contacts the connector receiving portion 13. Since it abuts on the body 18, static electricity is prevented from entering the connector receiving portion 13.

  The link mechanism 19 causes the connector receiving portion 13 to move from the inner side to the outer side in conjunction with the movement of the first lid body 17 and the second lid body 18 from the closed position to the open position. The connector insertion portion 15 and the connector receiving portion 13 in the middle of the insertion of the connector insertion portion 15 while the connection position between the connector insertion portion 15 and the connector receiving portion 13 is the external position. Can be kept long, and it is possible to earn time for the static electricity charged in the connector insertion portion 15 to flow to the first lid body 17 and the second lid body 18.

  Further, when the connector receiving portion 13 is fixed at a predetermined position, the connector receiving portion 13 must be disposed outside the rotation range of the first lid body 17 and the second lid body 18. Since the portion 13 once moves to the inside and then to the outside, the connector receiving portion 13 may overlap the rotation range of the first lid body 17 and the second lid body 18 when connected to the connector insertion portion 15. it can. That is, the position of the connector receiving portion 13 at the time of connection can be made closer to the outside.

  FIG. 5 is a plan view showing a connector insertion slot 101 to which the connector insertion slot structure of the second embodiment of the present invention is applied.

  Similar to the connector insertion port portion 1 of the first embodiment, the connector insertion port portion 101 includes a first lid body 17 and a second lid body 18 that are double-opened and open inward.

  However, the link mechanism 19 of the first embodiment is omitted. The connector receiving portion 13 is fixed to the base surface 11 outside the rotation range of the first lid body 17 and the second lid body 18. The connector insertion port portion 101 is a first torsion spring that exerts an urging force around the first rotation axis R1 and the second rotation axis R2 instead of the first torsion spring 31 and the second torsion spring 32 of the first embodiment. 131 and a second torsion spring 132 (only FIG. 5A is shown). The first lid body 17 and the second lid body 18 are biased from the open position to the closed position by the first torsion spring 131 and the second torsion spring 132. The first torsion spring 131 and the second torsion spring 132 may generate an urging force by a rewinding force or a urging force by a rewinding force in FIG. The case where it demonstrates is illustrated.

  In the second embodiment, when the connector insertion portion 15 is inserted into the opening 11h, the first lid body 17 and the second lid body 18 are moved from the closed position shown in FIG. 5 (a) to FIG. 5 (b). The connector insertion portion 15 and the connector receiving portion 13 are allowed to be connected. When the connector insertion portion 15 is removed, the first lid body 17 and the second lid body 18 return from the open position to the closed position by the urging force of the first torsion spring 131 and the second torsion spring 132.

  According to the second embodiment described above, similarly to the first embodiment, when the connector insertion portion 15 is inserted into the opening 11h, before the connector insertion portion 15 contacts the connector receiving portion 13, Since it abuts on the first lid 17 and the second lid 18, static electricity is prevented from entering the connector receiving portion 13. Furthermore, the configuration is very simple.

  FIG. 6 is a plan view showing a connector insertion slot 201 to which the connector insertion slot structure of the third embodiment of the present invention is applied.

  Similarly to the connector insertion port portion 101 of the second embodiment, the connector insertion port portion 201 has the connector receiving portion 13 disposed at a fixed position, and the opening 11h is opened and closed by an inner opening lid.

  However, the connector insertion opening 201 is opened and closed by a lid body 217 having a single opening 11h. The lid 217 is urged from the open position to the closed position around the rotation axis R201 by a torsion spring 231 similar to the first torsion spring 131 of the second embodiment.

  In the third embodiment, when the connector insertion portion 15 is inserted into the opening 11h, the lid body 217 and the lid body 217 move from the closed position shown in FIG. 6 (a) to the open position shown in FIG. 6 (b). Connection between the connector insertion portion 15 and the connector receiving portion 13 is allowed. When the connector insertion portion 15 is removed, the lid 217 returns from the open position to the closed position by the biasing force of the torsion spring 231.

  According to the third embodiment described above, as in the first and second embodiments, when the connector insertion portion 15 is inserted into the opening 11h, the connector insertion portion 15 contacts the connector receiving portion 13. Since it abuts on the lid 217 before, static electricity is prevented from entering the connector receiving portion 13. Furthermore, the configuration is very simple.

  FIG. 7 is a perspective view showing a connector insertion slot 301 to which the connector insertion slot structure of the fourth embodiment of the present invention is applied.

  Similar to the connector insertion port portion 1 of the first embodiment, the connector insertion port portion 301 includes a double lid first lid body 317 and a second lid body 318. However, the 1st cover body 317 and the 2nd cover body 318 are comprised so that it may be what is called an outward opening. Specifically, it is as follows.

  The connector insertion port portion 301 is a first guide portion that guides a first protrusion 317a as a guided portion provided at an end of the first lid 317 on the inner side of the opening 11h (second lid 318 side). One rail 321 is provided. The first rail 321 generally guides the first protrusion 317a in a direction that intersects the direction from the inner side to the outer side. Specifically, the first rail 321 is formed in an arc shape, for example. When the first lid 317 is in the closed position, the first rail 321 has an opening 11h outside (second lid) along a direction inclined from the outside to the inside with respect to the direction parallel to the base surface 11. The first protrusion 317a can be guided on the opposite side of the body 318 side. Further, the first rail 321 has a first protrusion on the outer side of the opening 11 h along a direction parallel to the base surface 11 and a direction inclined from the inner side to the outer side with respect to the direction parallel to the base surface 11. The part 317a can be guided.

  Similarly, the connector insertion port portion 301 is a guide portion that guides the second protrusion 318a as a guided portion provided at the end of the second lid 318 on the inner side of the opening 11h (first lid 317 side). As a second rail 322. The second rail 322 has the same configuration as the first rail 321. That is, the first rail 321 generally guides the second protrusion 318a in a direction intersecting the direction from the inner side to the outer side. Specifically, the second rail 322 is formed in an arc shape, for example. When the second lid 318 is in the closed position, the second rail 322 has an opening 11h outside (first lid) along a direction inclined from the outside to the inside with respect to the direction parallel to the base surface 11. The second protrusion 318a can be guided on the opposite side of the body 317 side. Further, the second rail 322 has a second protrusion on the outer side of the opening 11 h along a direction parallel to the base surface 11 and a direction inclined from the inner side to the outer side with respect to the direction parallel to the base surface 11. The part 318a can be guided.

  The connector insertion port 301 includes a third protrusion 317b as a guided part provided at the end of the first lid 317 on the center side of the opening 11h (the side opposite to the side where the first protrusion 317a is provided). It has the 3rd rail 323 as a guide part to guide. The third rail 323 is configured to be able to guide the third protrusion 317b in the direction from the inner side to the outer side.

  Similarly, the connector insertion port portion 301 has a fourth protrusion as a guided portion provided at the end of the second lid 318 on the peripheral edge side of the opening 11h (the side opposite to the side where the second protrusion 318a is provided). It has the 4th rail 324 as a guide part which guides the part 318b. The fourth rail 324 is configured to be able to guide the fourth protrusion 318b in the direction from the inner side to the outer side.

  The connector insertion opening 301 has a helical spring 325 that exerts a tensile force in a direction in which the first protrusion 317a and the second protrusion 318a are brought close to each other.

  In the connector insertion port portion 301, the connector receiving portion 13 is disposed at a fixed position. The connector receiving portion 13 is provided adjacent to the opening 11h. For example, the outer end surface of the connector receiving portion 13 is in contact with the inner surface of the base surface 11. Alternatively, the outer end surface of the connector receiving portion 13 is located on the outer side than the inner surface of the base surface 11.

  The first lid 317 and the second lid 318 are connected to the ground. For example, the first lid 317 and the second lid 318 are connected to the first rail 321 and the second rail 322 by connecting the first rail 321 and the second rail 322 to the reference potential of the electronic circuit 9 through a conductive wire or the like. The rail 322 is connected to the ground.

  FIG. 8 is a diagram for explaining the operation of the connector insertion slot 301.

  In FIG. 8A, the first lid 317 and the second lid 318 are in the closed position, and the opening 11h is closed. At this time, the first protrusion 317a of the first lid 317 is located at the end of the first rail 321 on the center side of the opening 11h, and the second protrusion 318a of the second lid 318 is positioned on the second rail 322. The third protrusion 317b of the first lid 317 is located at the end on the inner side of the third rail 323, and the fourth protrusion 318b of the second lid 318 is located at the end on the center side of the opening 11h. The fourth rail 324 is located at the inner end.

  In this state, when the insertion of the connector insertion portion 15 into the opening 11 h is started, the connector insertion portion 15 first comes into contact with the first lid body 317 and the second lid body 318. At this time, if the cable 5 is charged, the charged static electricity flows to the ground via the first lid 317 and the second lid 318.

  When the connector insertion portion 15 is further inserted, the first lid 317 and the second lid 318 are pushed by the connector insertion portion 15 as shown in FIG. 8B to FIG. 8E in order. The first rail 321, the second rail 322, the third rail 323, and the fourth rail 324 are guided and moved. At this time, as for the 1st cover body 317 and the 2nd cover body 318, one end (end part of the outer edge side of the opening 11h) is from the inner side to the outer side rather than the other end (end part of the center side of the opening 11h). Move like moving. And as shown in FIG.8 (e), if the 1st cover body 317 and the 2nd cover body 318 move to an open position, the connector insertion part 15 and the connector receptacle part 13 will be connected.

  When the connector insertion portion 15 is removed from the opening 11h, the first lid body 317 and the second lid body 318 are returned to the closed position by the biasing force of the spring 325.

  According to the above embodiment, as in the first to third embodiments, when the connector insertion portion 15 is inserted into the opening 11h, before the connector insertion portion 15 contacts the connector receiving portion 13, Since the first cover 317 and the second cover 318 are in contact with each other, static electricity is prevented from entering the connector receiving portion 13.

  Furthermore, since the first lid 317 and the second lid 318 move from the inner side to the outer side and move from the closed position to the open position, that is, they are so-called outwardly opened lid bodies. Compared to the case of the inward opening as in the first to third embodiments, the connector receiving portion 13 can be arranged on the outside side.

In addition, as described above, if the opening is inward, the lid body may be connected to the base surface so as to be rotatable around a rotation axis parallel to the base surface, or the flexible lid body may be suspended. It is simple. Moreover, if it opens outward, the receiving part of a connector can be arrange | positioned more outside, It is advantageous to size reduction of an electronic device etc.

  In the embodiment, the structure in which the connector receiving portion moves once to the inside side and then to the outside side in conjunction with the movement of the lid body from the closed position to the open position, Although shown only in the lid body of the embodiment, such a configuration may be applied to a lid body that is partially opened or outwardly opened. Further, the structure of the link mechanism may be appropriately configured.

  When the connector insertion part is removed, a force for returning the lid from the open position to the closed position may be obtained as appropriate. For example, in the third embodiment (FIG. 6), the force for returning the lid to the closed position is obtained by the spring. However, as in the fifth embodiment (FIG. 9), the force is returned by gravity. Also good. You may utilize the force which pulls out a connector insertion part.

  When returning to the closed position by a spring, an appropriate type of spring can be arranged at an appropriate position. For example, in the fourth embodiment (FIG. 7), the case where the helical spring 325 that exerts a tensile force is used is exemplified, but the first protrusion 317 a and the second protrusion 317 a are provided in the first rail 321 and the second rail 322. A spring that presses the protrusion 318a toward the center of the opening may be provided, or a spring that presses the first protrusion 317b or the second protrusion 318b toward the inside may be provided in the third rail 323 or the fourth rail 324. .

  The lid body may be connected to the ground by an appropriate method. That is, it may be connected via an appropriate member at an appropriate position of the lid.

  The movement range of the lid may be regulated by an appropriate method. For example, there is a stopper for preventing the lid body from moving from the closed position to the open position beyond the open position or from the open position to the closed position. It may be provided.
