With reference to FIG. 5 and FIG. 6, the form which connects the plug 50 to the outlet 10 is demonstrated.

As shown in FIG. 5 (a), the user adjusts the direction of the plug 50 so that the position display portion 54 is upward, and then moves it toward the outlet 10. As shown in FIG. 5B, when the protrusion 56 of the plug 50 contacts the contact protrusion 31 of the support plate 30, the support plate 30 is connected to the outlet body 20 and the support plate. With the connection position CP of 30 as a point, the front-end | tip part of the support plate 30 was tightened so that it may displace downward. That is, the support plate 30 is elastically deformed downward using the connection position CP as a point. When the plug 50 is further inserted from this state, as shown in Fig. 5C, after the protrusion 56 passes over the top of the contact protrusion 31, the supporting plate 30 is moved upward by the action of the restoring force. Is displaced toward. At this time, the plug pin 52 is inserted into the plug pin insertion hole 25 (see FIG. 2), and the plug 50 is connected to the outlet 10.

In this state, a slight gap is formed between the inner circumferential surface of the recess 24 and the outer circumferential surface of the plug body 51. Here, the "slight gap" is a gap so small that a user's finger cannot enter. As a result, when the plug 50 is inserted so as to be in the state of FIG. 5 (b) from FIG. 5 (b), the user's finger is suppressed from entering the recess 24.

As shown in FIG. 6, in the state where the plug 50 is connected to the outlet 10, that is, in the state of FIG. 5C, the contact protrusion 31 is accommodated in the front recess 59A. Specifically, as shown in FIG. 6 (a), the contact portion 34 of the contact projection portion 31 abuts on the contact surface 59C. 6 (b), the contact protrusion part 31 is arrange | positioned between the left-right direction Y of a pair of front side surface 59B, and is approaching each front side surface 59B. Specifically, the width T1 of the left and right directions Y of the front side surface 59B is approximately equal to the width T2 of the left and right directions Y of the two contact protrusions 31. In detail, the width T1 of the front side surface 59B is slightly larger than the width T2 of the contact protrusion 31. Accordingly, the support plate 30 fixes the plug 50. In detail, the contact protrusion 31 and the protrusion 56 are fixed to each other to prevent the plug pin 52 from being pulled out of the plug pin insertion port 25 (see FIG. 2).

With reference to FIG. 7, the form which removes the plug 50 from the outlet 10 is demonstrated.

As shown to Fig.7 (a), a user presses the front end part of the support plate 30 downward. In this state, the engagement of the projection 56 and the contact projection 31 is in a substantially shifted state. Then, when the user pulls the plug 50 forward, the plug 50 is pulled out from the outlet 10 as shown in Fig. 7B. At this time, when the user releases a finger from the support plate 30, the support plate 30 is displaced upward by the restoring force.

In the present embodiment, the following effects can be obtained.

[1] In the present embodiment, in a state where the plug 50 is connected to the outlet 10, the protrusion 56 of the plug 50 and the contact protrusion 31 of the support plate 30 abut. Accordingly, even if a force is inadvertently applied to the direction in which the plug 50 is pulled out of the outlet 10 by hanging the cable 53 of the plug 50 or the like, the plug 50 is pulled out of the outlet 10. Can be prevented.

By the way, as a fixing portion which prevents the plug from being pulled out from the outlet, the plug pin is connected to the plug receiving member and rotated by a predetermined angle to insert the projection provided in the plug receiving member into the through hole provided in the plug pin, thereby removing the plug from the outlet. A structure for preventing the fall out is considered.

The above structure generally assumes a case where the number of times of inserting and unplugging the plug is small, so that, for example, the number of times of inserting and unplugging the plug is often guaranteed about 100 times. Specifically, the plug receiver is elastically deformed by inserting the plug pin, and the projection of the plug receiver enters the transmission hole of the plug pin. If the elastic deformation of the plug receiver is repeated, the spring property of the plug receiver member is deteriorated, so that the projection of the plug receiver member does not enter the through hole of the plug pin. As a result, there is a case where the function of preventing the plug from being pulled out from the outlet may be lost while the plug is repeatedly inserted and removed. Therefore, the structure was unsuitable for many applications in which the plug was inserted and removed.

In view of this, in the present embodiment, the contact projections 31 are provided on the support plate 30, and the projections 56 of the plug 50 are fixed to the contact projections 31 so that the plugs from the outlet 10 can be plugged. Prevent 50 from falling out. Thereby, compared with the structure which prevents the plug pin and the plug receiving member from being detached, the number of guarantees which can prevent the plug from coming off from the outlet can be increased.

In addition, in the configuration in which the protruding portion 23 is omitted from the outlet main body 20, since the wall 5 and the support plate 30 may interfere, the positioning of the outlet 10 relative to the wall 5 is difficult. It is difficult. In this regard, in the present embodiment, positioning of the outlet 10 relative to the wall 5 can be easily performed by inserting the protrusion 23 into the opening 5A of the wall 5. Therefore, interference with the wall 5 and the support plate 30 can be suppressed. Thus, the outlet 10 can be easily attached to the wall 5.

[2] In the present embodiment, when the protruding portion 56 abuts on the contact protruding portion 31, the support plate 30 is bent downward with respect to the connecting position CP. As a result, the contact protrusion 31 is displaced toward the direction away from the protrusion 56. Therefore, since the projection part 56 can easily ride over the contact projection part 31, the insertion operation | movement of the plug 50 to the outlet 10 can be performed easily.

In addition, in the state where the plug 50 is connected to the outlet 10, the user presses the support plate 30 downward with a finger, and the support plate 30 is pulled downward using the connection position CP as a point. . Thereby, since the contact protrusion 31 of the support plate 30 moves toward the direction away from the protrusion 56 of the plug 50, the contact protrusion 31 when pulling out the plug 50 from the outlet 10 is carried out. The interference with the projection 56 can be suppressed. As a result, provision of a dedicated mechanism for moving the contact protrusion 31 toward the direction away from the protrusion 56 on the support plate 30 can be omitted, so that the support plate 30 can be simplified. .

[3] In the present embodiment, when the plug 50 is not connected to the outlet 10, the power supply inner door 41 and the grounding inner door 42 cover the plug pin insertion holes 25, respectively. Therefore, foreign matters such as insects can be prevented from entering the outlet 10 through the plug pin insertion port 25.

[4] In the present embodiment, the recess 24 is provided inside the protruding portion 23 so that the user's hand is recessed when the user connects the plug 50 to the outlet 10. It can suppress entering inside.

[5] In the present embodiment, the protruding portion 23 is inserted through the opening 5A of the wall 5 to position the outlet 10 relative to the wall 5. That is, the opening portion 5A serves as both of positioning the outlet 10 and exposing the plug pin insertion port 25 to the outside. Therefore, since the opening hole dedicated for inserting the protrusion 23 into the wall 5 can be omitted, the shape of the wall 5 can be simplified.

[6] In the present embodiment, the upper portion of the protruding portion 23 is curved while viewed from the front, and the lower portion is formed into a rectangular shape. That is, the shape of the protruding portion 23 is formed asymmetrically up and down. Thereby, the direction of the outlet 10 can be visually observed easily in the up-down direction Z. Therefore, the worker can easily perform the work of attaching the outlet 10 to the wall 5.

[7] In the present embodiment, in the state where the plug 50 is connected to the outlet 10, the contact protrusion 31 of the support plate 30 is attached to the front recess 59A of the protrusion 56 of the plug 50. Is accepted. Thereby, movement of the plug 50 to the left-right direction Y can be regulated.

According to this embodiment, the position display part 54 is provided in the plug 50, and the arrangement position of the plug pin 52 can be confirmed. Thereby, the operator can see the plug pin 52 directly, and the operation | work which confirms the arrangement position of the plug pin 52 can be skipped.
