As such a cover, a cover provided so as to be rotatable around an axis extending in the width direction of the outlet body and a cover provided so as to be slidable along the front surface of the outlet body are disclosed.

  And when using the power outlet, the user opens the above-mentioned insertion port by directly rotating or sliding the cover with a finger, and the power plug is inserted into the insertion port of the outlet body. The electrode is inserted. Further, in a state where the insertion port is closed by the cover, foreign matter does not enter the insertion port.

JP 2000-301991 A

  By the way, in such a power outlet, when the cover is provided so as to be rotatable about the shaft, the power outlet is used in a state where the cover protrudes toward the front side. In the case where the cover is slidable along the front surface of the outlet body, the power outlet is used with the cover protruding upward from the outlet body. Therefore, there is a possibility that the cover gets in the way or breaks.

  The objective of this invention is providing the power outlet which can suppress suitably that a cover obstructs or breaks.

  In order to achieve the above object, the power outlet according to the present invention is one in which the electrode of the power plug can be inserted, and can be moved back and forth on the back side of the opening formed in the mounting wall. A cover that is movable to a closed position that closes the opening and an open position that is spaced apart from the opening and opens the opening; and a cover that is movable along the wall surface of the mounting wall on the back side of the mounting wall and An outlet main body having a terminal into which an electrode is inserted, movable to a separated position separated from the opening and a neighboring position close to the opening; and movement of the cover from the closed position to the open position; and from the separated position An interlocking mechanism for interlocking movement of the outlet body to the proximity position, and the power source when the outlet body moves from the separated position to the proximity position The outlet body to the lug of the electrode is inserted into the terminal is configured.

  According to this configuration, when the power outlet is not used, the cover is located at a closed position that closes the opening of the mounting wall, and the outlet body is located at a separated position spaced from the opening. On the other hand, when using the power outlet, if the cover is moved from the closed position to the open position where the opening is opened by pushing the design surface of the cover with the tip of the power plug, the movement of the cover is interlocked. The outlet body moves from the separated position to a close position close to the opening. At this time, the electrode of the power plug is inserted into the terminal of the outlet body. Thus, according to the said structure, since a cover is always located in opening of an attachment wall, the unintended external force does not act with respect to a cover. Therefore, it can suppress suitably that a cover becomes obstructive or breaks.

Hereinafter, an embodiment in which the present invention is embodied as an in-vehicle power outlet will be described with reference to FIGS.
As shown in FIG. 1, a horizontally long rectangular opening 21 is formed in a flat mounting wall 20 constituting an outer wall of a center console in a vehicle interior, and a power outlet is provided in the opening 21 and on the back side of the mounting wall 20. 10 is provided.

  As shown in FIG. 2, a bottom wall 22 extends rearward at the lower edge of the opening 21 on the back side of the mounting wall 20. A rear wall 23 extends upward at the rear end of the bottom wall 22. A lateral wall 24 extends upward at both ends of the bottom wall 22.

  As shown in FIGS. 2 and 3, a cover 40 is provided on the bottom wall 22. The cover 40 moves between a closed position that closes the opening 21 and closes the opening 21, and an open position that is separated from the opening 21 and contacts the back wall 23 to open the opening 21. A second rail groove 24 b extends in the front-rear direction on the inner surface of the horizontal wall 24. Further, a protrusion 41a extends along the front-rear direction from the lower ends of both side surfaces of the cover body 41 of the cover 40. The protrusion 41a of the cover body 41 is engaged with the second rail groove 24b, and this guides the movement of the cover 40 in the front-rear direction.

  The cover body 41 has a box shape, and a rear surface that is opposite to the design surface 42 that is the front surface of the cover body 41 is open. The design surface 42 is formed with a recess 42 a having a vertical width slightly larger than the vertical width of the electrode 91 of the power plug 90 and having a horizontal width slightly larger than the horizontal width of the electrode 91. A support portion 43 is erected on the upper portion of the cover main body 41, and a shaft portion 44 projects from the tip thereof.

  A spring 60 is provided between the back wall 23 and the cover main body 41, and the cover main body 41 is biased toward the closed position, that is, forward by the spring 60. Note that the position of the spring 60 is regulated by a guide member (not shown) so that the entire spring 60 is expanded and contracted on substantially the same axis without being bent.

  As shown in FIGS. 2 to 4, an outlet body 30 is provided on the cover 40 so as to be movable up and down. The outlet body 30 moves between a separation position separated from the opening 21 and a proximity position close to the opening 21.

  As shown in FIG. 3, a first rail groove 24 a extends in the vertical direction on the inner surface of the horizontal wall 24. Further, protrusions 31 a extend from the both side surfaces of the accommodating portion 31 along the vertical direction. The first rail groove 24a is engaged with the protrusion 31a of the accommodating portion 31 constituting the outlet body 30, and this guides the elevation of the outlet body 30.

  As shown in FIGS. 2 and 3, the inclined portion 35 extends from the central portion in the width direction of the accommodating portion 31 of the outlet main body 30 so as to be located higher toward the rear side. A first groove 37 extending rearward is formed in the accommodating portion 31 and a part of the inclined portion 35. In addition, the inclined portion 35 is formed with a second groove 38 that is connected to the rear end of the first groove 37 and extends while being inclined so as to be positioned higher toward the rear side. The first groove 37 and the second groove 38 constitute a guide groove 36.

  The shaft portion 44 of the cover 40 is fitted in the guide groove 36. The accommodating portion 31 and the inclined portion 35 having the guide grooves 36 and the shaft portion 44 constitute an interlocking mechanism 50 that interlocks the movement of the cover 40 and the movement of the outlet body 30.

  As shown in FIGS. 3 and 4, a pair of connection terminals 71 made of metal leaf springs are housed in the housing portion 31, and a power supply line 72 is connected to the connection terminals 71. A pair of insertion ports 32 into which the electrodes 91 of the power plug 90 are inserted so as to correspond to the connection terminals 71 are formed in the front part and the lower part of the housing part 31.

Next, the operation of this embodiment will be described.
When the power outlet 10 is used, as shown by a two-dot chain line in FIG. 2, the cover 40 is closed as shown in FIG. Move backward from position. At this time, the shaft part 44 of the cover 40 moves in the first groove 37 of the outlet body 30 until the cover 40 reaches the position shown in FIG. Do not move.

  When the power plug 90 is further inserted from this state, the shaft portion 44 of the cover 40 relatively moves in the second groove 38 of the outlet body 30 that extends rearward and obliquely upward, so that the outlet body 30 is lowered. As shown in FIG. 7, when the cover 40 moves to the closed position, the outlet body 30 is lowered to the proximity position. When the outlet body 30 is lowered from the position shown in FIG. 6 to the position shown in FIG. 7, the electrode 91 of the power plug 90 is inserted into the insertion port 32, and the electrode 91 is connected to the connection terminal 71. (See FIG. 8).

  Here, the force with which the leaf spring constituting the connection terminal 71 clamps the electrode 91 is larger than the urging force of the spring 60 that urges the cover 40 toward the closed position. That is, when the power plug 90 is inserted, the cover 40 is not pushed back by the spring 60.

  On the other hand, when the power plug 90 is pulled out from the insertion port 32 of the outlet body 30, the electrode 91 is pulled out from the connection terminal 71 and the clamping pressure by the connection terminal 71 does not act. Therefore, the cover 40 is returned to the closed position shown in FIG. 2 by being biased by the spring 60. At this time, due to the action of the guide groove 36, the outlet body 30 returns to the separated position in the direction opposite to that when the power plug 90 is inserted.

  Thus, according to this embodiment, since the cover 40 is always located on the back side of the mounting wall 20, an unintended external force does not act on the cover 40. Therefore, the cover 40 is preferably prevented from getting in the way or broken.

According to the power outlet according to the present embodiment described above, the following effects can be obtained.
(1) The power outlet 10 is provided on the back side of the opening 21 formed in the mounting wall 20 so as to be movable back and forth. The power outlet 10 is close to the opening 21 and is separated from the closing position where the opening 21 is closed. A cover 40 that is movable to an open position that opens the opening 21 is provided. In addition, a connection terminal 71 is provided on the back side of the mounting wall 20 so as to be movable along the wall surface of the mounting wall 20 and into which the electrode 91 of the power plug 90 is inserted. An outlet main body 30 is provided that can be moved to a proximity position close to. In addition, an interlocking mechanism 50 that links the movement of the cover 40 from the closed position to the open position and the movement of the outlet body 30 from the separated position to the close position is provided. The outlet body 30 is configured such that the electrode 91 of the power plug 90 is inserted into the connection terminal 71 when the outlet body 30 moves from the separated position to the adjacent position.

  According to such a configuration, since the cover 40 is always located in the opening 21 of the mounting wall 20, an unintended external force does not act on the cover 40. Therefore, it can suppress suitably that the cover 40 becomes obstructive or damaged.

  Further, since the cover 40 does not protrude from the front surface of the mounting wall 20 when the power outlet 10 is used, the power plug 90 and the cover 40 do not interfere with each other. For this reason, the power plug 90 can be suitably inserted into the insertion port 32 of the outlet body 30.

Therefore, it can suppress suitably that the cover 40 becomes obstructive or damaged, and even if it is a large sized power plug 90, this can be inserted suitably.
(2) A spring 60 that biases the cover 40 toward the closed position is provided. According to such a configuration, when the power plug 90 is pulled out from the outlet body 30, the cover 40 is returned to the closed position by being biased by the spring 60. For this reason, the opening 21 of the mounting wall 20 is automatically closed by the cover 40. Therefore, the opening 21 of the mounting wall 20 can be easily closed, and foreign matter can be prevented from entering the opening 21 when the power outlet 10 is not used.

  (3) The design surface 42 of the cover 40 is formed with a recess 42 a that regulates the insertion posture of the power plug 90. According to such a configuration, when the design surface 42 of the cover 40 is pushed by the tip of the electrode 91 of the power plug 90, the insertion posture of the power plug 90 is restricted, so that the power plug 90 is displaced with respect to the cover 40. It can insert suitably.

-A power outlet is not restricted to what is provided in a center console, You may make it provide in other parts of vehicle interiors, such as an instrument panel. In addition, the present invention is not limited to an on-vehicle power outlet, and the present invention can also be applied to a residential power outlet.

  The power outlet 10 can be shaped to correspond to a three-phase power plug having three electrodes. In this case, the number of insertion ports and the number of terminals may be changed according to the number of electrodes. Further, the power outlet can be shaped to correspond to a coaxial power plug having a rod-like pin.

  -You may make it change suitably the shape and number of the recessed parts formed in the design surface of a cover according to the shape and number of the electrodes of a power plug. For example, a vertically long recess, that is, a vertically long recess, may be formed at two positions corresponding to the terminals of the outlet body.

-The recessed part 42a of the design surface 42 of the cover 40 is abbreviate | omitted, and the design surface of a cover can also be made into planar shape.
-You may make it abbreviate | omit the spring 60 and provide the urging | biasing member which urges | biases the electrical outlet main body 30 toward a separation position from a proximity position. In this case, when the power plug is pulled out from the outlet body, the outlet body is returned to the separated position and the cover is returned to the closed position by being biased by the biasing member. For this reason, the effect according to the effect (2) of the said embodiment can be show | played.
