Energize.

  An operation handle 13e that protrudes outward is integrally formed on the upper side 13d of the lid 13. The handle 13e is formed by being separated from the upper side portion 13d by a predetermined distance b (FIG. 2). As a result, a bank-like closed portion 13f is formed between the handle 13e and the upper side portion 13d. Thereby, when the handle 13e for operation is provided on the lower side portion 13a of the lid body 13, that is, the side opposite to the rotating shaft side, it is separated from the end portion of the lid body 13, that is, the upper side portion 13d by the distance b. The handle 13e for operation can be provided at the position where the wall is separated, that is, the closed portion 13f serves as a barrier surface against the intrusion of water, dust, etc., preventing or suppressing the ingress of water into the main body 11 of the outlet. It becomes possible to do. In the present embodiment, the interval dimension b is set to about 3 mm.

  In FIG. 2, 13e1 is a tool insertion recess formed from the upper surface of the substantially intermediate portion in the longitudinal direction of the handle 13e to the wall surface of the closing portion 13f, and releases the engagement means 18 between the cover member 14 and the main body 11 described later. This is a recess for inserting a tool such as a screwdriver.

  As described above, the lid 13 provided so as to be rotatable with respect to the main body 11 between the closed position that covers the insertion port 12a of the outlet unit 12 and the open position that opens is shown in FIGS. As shown in FIG. 6, a locking portion 13h is provided for opening the plug P with one hand by operating the plug in a locked state where at least a part of the plug P can be locked.

 In this embodiment, the locking portion 13h is formed by a recess in which the plug blade P1 of the plug P is locked, and the recess has a predetermined distance b from the upper side portion 13d of the lid 13 as described above, and the handle 13e. Is formed integrally with the bank-shaped blocking portion 13f formed by forming a notch, with a substantially middle portion in the longitudinal direction cut away, and further integrated with the tool insertion recess 13e1 formed on the handle 13e. Formed.

 As a result, as shown in FIG. 4 (a), the plug blade P1 of the plug P grasped with one hand, in this embodiment, the tip of the grounding blade blade P1 that protrudes the longest is inserted into the recess 13h. While stopping and catching, as shown in FIG. 4B, the lid 13 can be easily opened as it is with one hand gripped in the direction of arrow C around the shaft 15a.

 In particular, in the present embodiment, the recess 13h serving as the locking portion is formed integrally with the tool insertion recess 13e1 formed in the handle 13e so that the tip of the plug blade P1 of the plug P grasped with one hand is recessed 13h. The tool insertion recess 13e1 acts as a guide to the recess 13h when it is inserted into the recess 13h, and it is easily and securely inserted and locked into the recess 13h with one hand grasped, and the lid 13 is easily and reliably opened. It becomes possible to do.

 In particular, in the present embodiment, the tool insertion recess 13e1 that functions as a guide is formed larger than the recess 13h, so that the guide function can be more effectively performed. In other words, the tool insertion recess 13e1 for removing the cover member 14 from the main body 11 also serves as a guide for the locking portion for opening the lid 13 with one hand, thereby simplifying the configuration of the outlet itself. It becomes possible to do. The lid 13 can also be opened by grasping the handle 13e.

  Further, as shown in FIG. 3, a protrusion 13 g is integrally formed on the inner surface of the lid body 13. The protruding portion 13g serves to prevent or suppress entry of water, dust and the like into the insertion port 12a of the outlet unit 12 described above at the closed position of the lid 13, and the insertion port 12a is formed. The arch-shaped ridge portion 12d is formed in an arch-like shape that substantially matches the outer peripheral portion of the arch-shaped ridge portion 12d so that the top surface of the ridge portion 13g contacts the top surface of the ridge portion 12d of the recessed fitting portion 12c. .

  Thereby, even if water invades from the gap between the lid 13 and the cover member 14, particularly the upper and side gaps, the top surfaces of the ridge portion 12 d and the ridge portion 13 g come into contact with each other, A kind of bank is formed, and it becomes possible to relieve the momentum of water transmitted from the gap and prevent or suppress the intrusion of water into the insertion port 12a. Incidentally, when there is no ridge portion 13g or the ridge portion 12d, the water transmitted from the gap may vigorously travel through the inner surface of the flat lid body and enter the insertion port 12a from the recessed fitting portion 12c. .

  Further, the arch-shaped protrusion 13g functions as a reinforcing rib when the lid 13 is formed of a synthetic resin, and the lid can be made thin. This eliminates the need to construct a thick lid, eliminates the need for a design for preventing the shrinkage, improves the degree of freedom in design, reduces the material cost, and is advantageous in terms of cost. .

  In addition, since the lid body 13 has the ridge portion 13g forming a rib for reinforcement, it is difficult to cause shrinkage, thin resin molding is possible, and the lid body is difficult to deform. The contact state with the jetty portion 12d can be maintained without a gap, and the momentum of water transmitted from the gap can be relaxed to reliably prevent or suppress the entry of water into the recessed fitting portion 12c. become.

  In the present embodiment, the ridge portion 13g is formed in an arch shape, and the ridge portion 13g is positioned with respect to the upper and both side portions and further the lower portion of the recessed fitting portion 12c. In many cases, since the water that has entered from the upper gap is transmitted through the upper jetty portion 12d, it is sufficient to form the ridge portion 13g corresponding to the upper semicircular portion of the circular recessed fitting portion 12c. And the protrusion part 13g should just be provided so that the upper part of the insertion port 12a may be covered at least.

  Further, a lock portion 16 is integrally formed at a substantially central portion of the inner surface of the lid 13. The lock portion 16 is configured by a hook-like engaging claw that engages the plug P connected to the blade bracket 12b on the main body 11 side and serves to prevent removal.

  The lid 13 is configured as described above, and closes the insertion port 12a of the outlet unit 12 and the opening 14d of the cover member 14 when not in use when the plug P is not connected, as shown in FIG. It plays the role of waterproofing and dustproofing. At the same time, by grasping the handle 13e with a finger from the opening 14d of the cover member 14 and opening it in the direction indicated by the arrow C in FIG. 2, the insertion port 12a is exposed to the outer surface as shown in FIG. The plug P can be inserted into the blade receiving bracket 12b from the insertion port 12a.

  In this embodiment, as shown in FIGS. 4A, 4B, and 4C, the tip of the grounding blade P1 of the plug P is inserted into the recessed portion 13h, locked, and hooked. 13 can be easily opened with one hand, and as shown in FIG. 5, each plug blade P1 of the plug P can be directly inserted into the blade receiving bracket 12b from the insertion port 12a with one hand.

  Further, when the plug P is inserted into the blade bracket 12b, as shown in FIG. 5, the lock formed on the outer surface (the lower surface in FIG. 5) of the plug P by the movement of the plug P in the direction of arrow D in FIG. The engaging claw of the lock portion 16 is engaged with the stepped portion P2, and the plug is prevented from coming off. This retaining is achieved by sliding the plug P toward the arrow D direction with respect to the cover body that is normally biased in the closing direction by the elasticity of the spring provided on the cover body 13. The engaging claw is automatically engaged with the step portion P2 of the plug P, and is automatically released by an operation (operation in the direction of arrow C) for opening the lid 13 from the engaged state.

  As shown in FIG. 7, the cover member 14 has a box shape made of a synthetic resin having electrical insulation, and similarly the upper surface plate 14 a so as to substantially cover the box-shaped main body 11 from the vertical and horizontal directions. The lower surface plate 14b and the side surface plates 14c and 14c are formed so that a cross section with the front surface and the back surface opened has a rectangular box shape. The inner shape and dimensions of the cover member 14 are formed to be slightly larger than the outer shape and dimensions of the main body 11, and the main body 11 is inserted into the cover member 14 and fitted with a slight gap.

  The front surface of the cover member 14 has an opening 14d through which the plug blade P1 of the plug P is inserted substantially in the middle thereof. The opening 14d is opposed to the upper and lower sides of the opening 14d and is integrally formed in a bowl shape toward the opening 14d. A pair of formed edge portions 14e and 14e is formed. Thus, the overall shape of the cover member 14 is configured to form a substantially frame shape having a depth by the opening 14d, the upper and lower edges 14e, and the left and right side plates 14c and 14c.

  Then, the cover member 14 having a substantially frame shape is covered with the main body 11 so as to substantially cover the entire main body 11. That is, the back side of the cover member 14 that is opened is inserted and fitted so as to face the front side of the main body 11. This insertion direction is a direction (in the direction of arrow A in FIG. 1) substantially orthogonal to the installation part X when the main body 11 is installed in the installation part X, and covers the main body 11 with the cover member 14. Insert it like this.

  Thereby, the upper surface plate 11a, the lower surface plate 11b and the both side surface plates 11c, 11c of the main body 11 are covered by the upper surface plate 14a, the lower surface plate 14b and the both side surface plates 14c, 14c of the cover member 14, and at the same time, the opening 14d is The outlet 12a of the outlet unit 12 provided in the front plate 11d, that is, the concave fitting portion 12c having the jetty portion 12d is mounted so as to face each other so as to be exposed on the outer surface. Furthermore, the cover member 14 is formed in a substantially frame shape so as to cover the outer peripheral portion including the attachment portions 11e and 11e of the main body 11, and waterproofing and dustproofing can be achieved in the attachment portion 11e, particularly the upper and lower attachment holes 11f.

  The main body 11 and the cover member 14 mounted as described above are detachably locked by the locking means 17 and further engaged and mounted by the detachable engaging means 18.

  First, the locking means 17 will be described. As shown in FIG. 6, the locking means 17 includes a locking member 17a formed between the upper surface plate 11a of the main body 11 and the inner surface of the upper surface plate 14a of the cover member 14, and this locking member is inserted. It has a latch receiving member 17b.

  In this embodiment, the locking member 17a has a substantially inverted T-shaped cross section and is formed of a wide locking plate 17a1 having a predetermined width, and a T-shaped base portion is formed on the inner surface of the upper surface plate 14a of the cover member 14. They are integrally formed (FIG. 6B).
