  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

<First Embodiment>
1 to 8 show a first embodiment. FIG. 1 is a cross-sectional view showing a state in which the lid member is restricted in rotational movement to prevent the connection plug from being detached, and FIG. 2 is a partially enlarged view of part A in FIG. .

  In the figure, 1 is a lid member, and 2 is a main body housing in which the lid member 1 is openable and closable. In the state where the lid member 1 is opened, the connection terminal 9 is disposed so as to be exposed in the main body casing 2 and is connected to an electric circuit (not shown) inside the main body casing 2. A connection plug 8 is connected to the connection terminal 9. The connection plug 8 is a connection plug to an external power source, an external output plug, an external input plug, or the like.

  Reference numeral 3 denotes an operation knob that is arranged on the external part of the main body housing 2 so as to be slidable in the vertical direction in the figure. One end of the operation knob spring 7 is fixed to the operation knob 3, and the other end is fixed to a fixing portion (not shown) inside the main body housing 2. As a result, the operation knob 3 is urged to a lower position (hereinafter referred to as a lid member approaching side) in FIG. 1 and is slid to an upper position (hereinafter referred to as a lid member separating side) in the figure by manual operation. It is possible. Further, the movement regulating spring member 5 is fixed to the operation knob 3 in a state where the distal end side elastically deformable.

  The distal end portion 5a of the movement regulating spring member 5 urged to the lid member approaching side together with the operation knob 3 by the operation knob spring 7 falls between the teeth of the latch portion 1b provided around the rotation shaft 1a of the lid member 1. Yes. The teeth of the latch portion 1b form a vertical surface facing the tip portion 5a substantially parallel to the opening direction of the lid member 1 and form an inclined surface with respect to the tip portion 5a in the closing direction of the lid member 1. . Therefore, when the lid member 1 is rotated in the opening direction, the vertical surface of the latch portion 1b and the tip end portion 5a of the movement restricting spring member 5 are brought into contact with each other so that the movement restricting spring member 5 Since the force is applied in the direction of the fixed portion, the distal end portion 5a is not elastically deformed in the direction of retracting from the teeth of the latch portion 1b. Then, although the operation knob 3 is moved together with the movement regulating spring member 5 to the side away from the lid member, it cannot be easily moved by the urging force of the operation knob spring 7, so that the lid member 1 opens with respect to the body housing 2. It is in a state where the rotational movement restriction in the direction is applied.

  On the contrary, when the lid member 1 is rotated in the closing direction, the distal end portion 5a of the movement restricting spring member 5 is elastically deformed so as to be separated from the teeth of the latch portion 1b along the inclined surface of the latch portion 1b. Therefore, the lid member 1 can be easily rotated in the closing direction with respect to the main body housing 2. In this way, the lid member 1 can be closed until the inner wall of the lid member 1 abuts against the outer shape of the connection plug 8, but after the abutment, the opening direction is restricted so that the lid member 1 cannot move easily. In this state, since the connection plug 8 abuts against the inner wall of the lid member 1, movement in the removal direction is restricted and prevented from coming off.

  Reference numeral 4 denotes an operation knob locking member. One end of an operation knob locking spring 6 is fixed to the operation knob locking member 4. The other end of the operation knob locking spring 6 is fixed to a fixing portion (not shown) inside the main body housing 2. As a result, the operation knob locking member 4 is biased in the clockwise direction about the rotation shaft 4a. When the operation knob 3 is manually moved to the lid member separation side, the operation knob locking member 4 comes into contact with the inclined contact surface 3a of the operation knob 3 and the locking portion 4b of the operation knob locking member 4, and the operation knob engagement Against the biasing force of the stop spring 6, it rotates in the counterclockwise direction around the rotation shaft 4 a. Thereafter, even if the operation knob 3 further moves toward the lid member separating side, the operation knob locking member 4 moves while contacting the inclined contact surface 3a, so that the operation knob locking member 4 rotates counterclockwise. to continue.

  FIG. 3 is a cross-sectional view showing a state where the rotational movement restriction of the lid member is released, and FIG. 4 is a partially enlarged view of a portion B in FIG.

  As shown in the figure, when the operation knob 3 is operated to the vicinity of the moving end on the lid member separation side, the locking portion 4b of the operation knob locking member 4 is detached from the inclined contact surface 3a of the operation knob 3, and the operation knob locking member 4 is rotated clockwise around the rotation shaft 4a by the biasing force of the operation knob locking spring 6. Then, the engagement contact surface 3b of the operation knob 3 and the engagement portion 4b of the operation knob engagement member 4 are engaged, and the operation knob 3 is prohibited from returning to the lid member approaching side. At this time, the distal end portion 5a of the movement regulating spring member 5 integral with the operation knob 3 is separated from the latch portion 1b of the lid member 1, so that the lid member 1 is in a state shown by a broken line in FIGS. In addition, it can be moved in the opening direction. Moreover, it can move also in the closing direction.

  FIG. 5 is a cross-sectional view showing a state in which the lid member is returned from the rotational movement restriction release state to the rotational movement restriction state, and FIG. 6 is a partial enlarged view of a portion C in FIG.

  In the process of further opening the lid member 1 from the state shown by the broken lines in FIGS. 3 and 4 to the vicinity of the open end, the release portion 1c of the lid member 1 comes into contact with the release slope portion 4c of the operation knob locking member 4, and When the member 1 is rotated in the opening direction, the release portion 1c pushes the release slope portion 4c and rotates the operation knob locking member 4 counterclockwise around the rotation shaft 4a against the urging force of the operation knob locking spring 6. Rotate in the direction. When the operation knob locking member 4 rotates counterclockwise, the locking portion 4b of the operation knob locking member 4 is disengaged from the engagement contact surface 3b of the operation knob 3, so that the operation knob 3 is operated. Due to the biasing force of the knob spring 7, the knob member 7 moves toward the lid member approaching side to a position where it abuts on the vertical surface of the latch portion 1 b of the lid member 1. Then, the lid member 1 is again restricted in rotation in the opening direction, and can be easily moved in the closing direction. When the lid member 1 is closed until it hits the outer shape of the connection plug 8, the state returns to the state shown in FIGS. 1 and 2, and the movement of the connection plug 8 in the removal direction is restricted.

  FIG. 7 is a view showing the operation from the closed state of the lid member to the state where the lid member of FIG. By operating in the order of FIG. 7 (a) → FIG. 7 (b) → FIG. 7 (c) → FIG. 7 (d), the lid member 1 moves from the closed state in which the connection plug 8 is not attached to FIGS. The lid member 1 is restricted in rotational movement, and the connection plug 8 is prevented from coming off.

  FIG. 7A shows a state in which the connection plug 8 is not attached and the lid member 1 is closed with respect to the main body housing 2. FIG. 7B shows a state in which the operation knob 3 is moved to the lid member separating side from the state of FIG.

  The operation knob 3 is prohibited from moving toward the lid member approaching side due to the locking of the operation knob locking member 4. Since the movement restricting spring member 5 is separated from the latch portion 1b of the lid member 1, the lid member 1 can be rotated in the opening direction, and can also be rotated in the closing direction after moving to the open state.

  FIG. 7C shows a state in which the lid member 1 is rotated to the vicinity of the open end.

  Since the lid member 1 retracts the operation knob locking member 4 from the operation knob 3, the operation knob 3 moves to the side closer to the lid member, and the movement of the lid member 1 is again restricted in the opening direction, and in the closing direction. Can be moved. With the lid member 1 opened, the connection plug 8 is attached to the connection terminal 9 as shown in FIG. 7D, and then the lid member 1 is abutted against the connection plug 8 by the inner wall, and further in the closing direction. It is rotated until it can no longer be rotated, and the state shown in FIGS.

  FIG. 8 is a perspective view of the lid member. 8A shows a state in which the connection plug 8 of FIGS. 1 and 2 is closed until it is prevented from being removed, and FIG. 8B shows a state in which the lid member 1 of FIGS. 5 and 6 is opened to the open end. .

  Further, a rotation restricting rib 1d is provided on the inner wall of the lid member 1 so that the connection plug 8 is provided close to the side surface 2 in a direction to restrict the movement of the connection plug 8 in the torsional direction. If the cable 8a of the connection plug 8 extends to the outside if the rotation exceeds a predetermined value, the cable 8a and the rotation restricting rib 1d come into contact with each other and cannot rotate any more, and the connection plug 8 moves relative to the main body housing 2. Is regulated. This also makes it difficult for the connection plug 8 to come off.

  Even if the connection plug 8 does not fit in the state where the lid member 1 is partially closed with respect to the main body housing 2 as in the present plan, the connection plug 8 can be prevented from being inadvertently removed. 8 is not required to be housed in the main body housing 2 with the lid member 1 closed, which is effective in reducing the size of the main body housing 2.

  1 and 2, when the lid member 1 is forced to open in the opening direction and the lid member 1 is forced to open in the opening direction, the movement regulating spring member 5 opposes the biasing force of the operation knob spring 7. Since the operation knob 3 moves to the lid member separating side, the lid member 1 is not destroyed. In consideration of such a case, the operation knob spring 7 causes the lid member 1 to be in the rotation restricted state in the opening direction, and the urging force is not broken when the lid member 1 is forcibly opened in the opening direction. It is set to.

<Second Embodiment>
9 to 13 show a second embodiment. FIG. 9 is a perspective view of the lid member. FIG. 9A shows a state in which the connection plug 8 is closed until it is prevented from coming off, and FIG. 9B shows a state in which the connection plug 8 is not attached and the lid member 11 is closed with respect to the main body housing 12. ing.

  FIG. 10 is a cross-sectional view showing a state in which the lid member is slidably restricted to prevent the connection plug from being removed. 11 is a lid member, and 12 is a main body housing in which the lid member 11 is slidably openable. In the state where the lid member 11 is open, the connection terminal 9 is disposed so as to be exposed in the main body casing 12 and is connected to an electric circuit (not shown) inside the main body casing 2. A connection plug 8 as in the first embodiment is connected to the connection terminal 9.

  Reference numeral 13 denotes an operation knob that is arranged on the external part of the main body housing 12 so as to be slidable in the vertical direction in the figure. One end of the operation knob spring 17 is fixed to the operation knob 13, and the other end is fixed to a fixing portion (not shown) inside the main body housing 2. As a result, the operation knob 13 is urged to a lower position (hereinafter referred to as a lid member approaching side) in FIG. 10 and is slid to an upper position (hereinafter referred to as a lid member separating side) in the figure by manual operation. It is possible. In addition, the movement regulating spring member 15 is fixed to the operation knob 13 in a state where the distal end side elastically deformable.

  The distal end portion 15 a of the movement regulating spring member 15 urged toward the lid member approaching side together with the operation knob 13 by the operation knob spring 17 falls between the teeth of the latch portion 11 b provided in a part of the lid member 11. The teeth of the latch portion 11b form a vertical surface facing the tip portion 15a in the opening direction of the lid member 11 and substantially parallel to the tip portion 15a, and form an inclined surface with respect to the tip portion 15a in the closing direction of the lid member 11. . Therefore, when the lid member 11 is slid in the opening direction, the vertical surface of the latch portion 11b and the tip end portion 15a of the movement restricting spring member 15 are brought into contact with each other in a substantially right direction, and the movement restricting spring member 15 is connected to the operation knob 13. Since the force is applied in the direction of the fixed portion, the distal end portion 15a is not elastically deformed in the direction of retracting from the teeth of the latch portion 11b. Then, although the operation knob 13 is moved together with the movement regulating spring member 15 to the side away from the lid member, it cannot be easily moved by the urging force of the operation knob spring 17, so the lid member 11 opens with respect to the main body housing 12. It is in a state where the slide movement restriction in the direction is applied.

  On the contrary, when the lid member 11 is rotated in the closing direction, the distal end portion 15a of the movement restricting spring 15 is elastically deformed so as to be retracted from the teeth of the latch portion 11b along the inclined surface of the latch portion 11b. Therefore, the lid member 11 can be easily slid in the closing direction with respect to the main body housing 12. In this way, the lid member 1 can be closed until the inner side wall of the lid member 11 hits the outer shape of the connection plug 8, but the opening direction cannot be easily moved because the movement is restricted. In this state, since the connection plug 8 abuts against the inner wall of the lid member 11, movement in the removal direction is restricted and is prevented from coming off.

  Reference numeral 14 denotes an operation knob locking member. One end of an operation knob locking spring 16 is fixed to the operation knob locking member 14. The other end of the operation knob locking spring 16 is fixed to a fixing portion (not shown) inside the main body housing 12. As a result, the operation knob locking member 14 is biased in the clockwise direction about the rotation shaft 14a. When the operation knob 13 is manually moved to the lid member separation side, the operation knob locking member 14 comes into contact with the inclined contact surface 13a of the operation knob 13 and the locking portion 14b of the operation knob locking member 14, and the operation knob engagement. Against the biasing force of the stop spring 16, it rotates in the counterclockwise direction around the rotation shaft 14 a.

  FIG. 11 is a cross-sectional view showing a state in which the sliding movement restriction is released on the lid member.

  As shown in the figure, when the operation knob 13 is operated to the vicinity of the moving end on the lid member separating side, the locking portion 14b of the operation knob locking member 14 is detached from the inclined contact surface 13a of the operation knob 13, and the operation knob locking member 14 rotates in the clockwise direction around the rotation shaft 14 a by the biasing force of the operation knob locking spring 16. Then, the engagement contact surface 13b of the operation knob 3 and the locking portion 14b of the operation knob locking member 14 are engaged, and the operation knob 13 is prohibited from returning to the lid member approaching side. At this time, the movement restricting spring engaging portion 12a fixed to the main body housing 12 is engaged with the slope portion of the retracting engaging portion 15b of the movement restricting spring member 15, and the distal end portion 15a of the movement restricting spring 12 is moved from the latch portion 11b. Elastically deformed to retract. Therefore, the distal end portion 15a of the movement regulating spring member 15 integral with the operation knob 13 is away from the latch portion 11b of the lid member 11, so that the lid member 11 opens in the opening direction as shown by the broken line in FIG. It is possible to move both in the closing direction.

  12 is a cross-sectional view showing a state in which the lid member is returned from the slide movement restriction release state to the slide movement restriction state. In the process of opening the lid member 11 from the state indicated by the broken line in FIG. The release portion 11c of the member 11 comes into contact with the release slope portion 14c of the operation knob locking member 14, and when the lid member 11 is further slid in the opening direction, the release portion 11c pushes the release slope portion 14c, The stop member 14 is rotated counterclockwise about the rotating shaft 14a against the urging force of the operation knob locking spring 16. When the operation knob locking member 14 rotates counterclockwise, the locking portion 14b of the operation knob locking member 14 is disengaged from the engagement contact surface 13b of the operation knob 13, so that the operation knob 13 is operated. Due to the urging force of the knob spring 17, the knob spring 17 moves toward the lid member approaching side to a position where it abuts on the vertical surface of the latch portion 1 </ b> C of the lid member 11. Then, the lid member 11 is again restricted from moving in the opening direction and can be easily moved in the closing direction. When the lid member 11 is closed until it hits the outer shape of the connection plug 8, the state shown in FIG. Returning and movement of the connecting plug 8 in the pulling direction are restricted.

  FIG. 13 is a sectional view showing the operation from the closed state of the lid member to the state where the lid member shown in FIG. By operating in the order of FIG. 13 (a) → FIG. 13 (b) → FIG. 13 (c) → FIG. 14 (d), the lid member 11 is moved from the closed state in which the connection plug 8 is not attached to the lid of FIG. The member 11 is regulated to slide and the connection plug 8 is prevented from coming off.

  FIG. 13A shows a state in which the connection plug 8 is not attached and the lid member 11 is closed with respect to the main body housing 12. FIG. 13B shows a state in which the operation knob 13 is moved to the lid member separating side from the state of FIG.

  The operation knob 13 is prohibited from moving toward the lid member approaching side due to the locking of the operation knob locking member 14. Since the movement restricting spring member 15 is separated from the latch portion 11b of the lid member 11, the lid member 11 can be slid in the opening direction, and can be slid in the closing direction after moving to the open state.

  FIG. 13C shows a state in which the lid member 1 is slid to the vicinity of the open end.

  Since the lid member 11 has retracted the operation knob locking member 14 from the operation knob 13 and the operation knob 13 has moved to the lid member proximity side, the lid member 11 is again restricted from moving in the opening direction. The movement in the closing direction is possible. With the lid member 11 open, the connection plug 8 is attached to the connection terminal 9 as shown in FIG. 13D, and then the inner wall of the lid member 11 abuts against the connection plug 9 and closes further. 10 until it can no longer slide. The rotation regulating rib 11d of the lid member 11 brings the connection plug 8 close to the side surface 2 direction. Since the cable 8a extends to the outside, the connection plug 8 cannot rotate any more because the cable 8a and the rotation restricting rib 11d are in contact with each other.

  According to the present plan, it is possible to prevent the connection plug 8 from being inadvertently disconnected without closing the lid member 11 with respect to the main body housing 12, so that the cable 8 of the connection plug 8 attached to the lid member 11 is cut off. Since it is not necessary to provide a notch, there is an effect that a member or a mechanism for closing the notch provided in the lid member 11 is not required when the connection plug 8 is not used.

  Further, a rotation restricting rib 11d is provided on the inner wall of the lid member 11 so that the connecting plug 8 is provided close to the side surface 2 in the direction of the side surface, thereby restricting the movement of the connecting plug 8 in the torsional direction. If the cable 8a of the connection plug 8 is extended outside when the rotation exceeds a predetermined value, the cable 8a and the rotation restricting rib 11d come into contact with each other and cannot be rotated any further, and the movement of the connection plug 8 relative to the body housing 12 Is regulated. This also makes it difficult for the connection plug 8 to come off.

  In addition, when the lid member 11 of FIG. 10 is in the sliding movement restricted state in the opening direction, if the lid member 11 is forcibly opened in the opening direction, the movement regulating spring member 15 against the urging force of the operation knob spring 17. Since the operation knob 13 moves to the lid member separating side, the lid member 11 is not destroyed. Considering such a case, the operation knob spring 17 is not broken when the lid member 11 is in the sliding movement restricted state in the opening direction and the lid member 11 is forced to move in the opening direction. The biasing force is set.
