DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0014]
[0015]
[0016]
[0017]
[0018]
[0019]
[0020]
1 to 4 show a receptacle 28 showing a first example of an embodiment of the present invention.
[0021]
The receptacle 28 of the first example is composed of a connector box 29 for connecting a power plug and a connector box storage box 30 for storing the connector box 29.
[0022]
The connector box 29 is provided with a cylindrical receiving portion 31 at the center of the cube, a handle portion 32 is attached to the upper end surface, and a contact pin 33 projects from the inside of the receiving portion 31. The contact pin 33 is connected to the connection fitting 34 and communicates with the power supply via a cable 35 extending from the back surface of the connector box 29. The energizing plug connected to the connector box 29 is configured in substantially the same manner as the conventional example.
[0023]
The connector box storage box 30 is composed of a bottom plate 36 and both side plates 37, 37, and substantially forms an inner frame portion 40 that substantially matches the lower surface 38 and the side surface 39 of the connector box 29, and opens upward and slightly larger than the inner frame portion 40. A box-shaped outer frame portion 41, and the outer surface of the inner frame portion 40 and the inner surface of the outer frame portion 41 are connected by a spring 42 so that a constant distance is provided between the outer frame portion 41 and the inner frame portion 40. The outer frame portion 41 supports the inner frame portion 40 so as to have Further, a guide portion 43 that extends from the inside to the upper outside is provided at the upper end of the inner frame portion 40.
[0024]
As shown in FIG. 1 , the front plate 44 of the connector box storage box 30 has a notch from the upper center to the lower side so as not to obstruct the cylindrical receiving portion 31 of the connector box 29. Similarly, a cut is made from the upper center to the lower side so as not to obstruct the cable 35.
[0025]
The operation of the first example of the embodiment of the present invention will be described below.
[0026]
The connector box 29 is gripped by the manipulator 32 and inserted into the connector box storage box 30 from above or pulled out from the connector box storage box 30, resulting in remote operation. Thus, the connector box 29 can be stored in the connector box storage box 30 or the connector box 29 can be removed from the connector box storage box 30.
[0027]
Further, since a guide portion 43 that extends from the inside to the outside is provided at the upper end of the inner frame portion 40 of the connector box storage box 30, the connector box 29 is moved from the upper side to the lower side of the connector box storage box 30 in remote operation. Even when the connector box 29 is slightly deviated from the storage position above the connector box storage box 30 when stored in a lowered position, the connector box 29 is corrected by the guide portion 43 and is guided to an accurate position. The storage box 30 can be securely stored.
[0028]
Further, when the power plug is connected to the connector box 29 by remote control, the connector box 29 is stored in the connector box storage box 30 in advance, and the power plug is held by the manipulator so as to be approximately aligned with the axis of the receiving portion of the connector box 29. Move to match. At this time, even if the axis of the connecting portion of the energizing plug is slightly deviated from the receiving portion 31 of the connector box 29, the receiving portion 31 of the connector box 29 is guided by the connecting portion of the energizing plug and supported by the spring 42. The connector box 29 moves together with the inner frame portion 40, and the axis of the connecting portion of the energizing plug matches the receiving portion 31 of the connector box 29 so that the energizing plug can be connected to the connector box 29. Furthermore, after the connection, the connector box 29 can return to its original position with the energizing plug by the elastic force of the spring 42 of the connector box storage box 30.
[0029]
Incidentally, the receptacle 28 of the first embodiment, rather than be limited to the embodiments described above, it without departing from the scope and spirit of the present invention that various changes and modifications may be made as a matter of course.
[0030]
【The invention's effect】
According to the receptacle of the present invention, various excellent effects can be obtained as described below.
[0031]
I) According to the first aspect, the connector box can be housed by inserting it into the connector box housing box from above, or can be removed by pulling the connector box upward. In addition, when connecting the power plug to the connector box, the connector box receiving portion is connected to the power plug connecting portion even if the axis of the power plug connecting portion is slightly deviated from the connector box receiving portion. The connector box moves together with the inner frame portion guided by the spring and supported by the spring, and the axis of the connecting portion of the energizing plug matches the receiving portion of the connector box so that the energizing plug can be connected to the connector box. Furthermore, after the connection, the connector box can return to its original position with the energizing plug by the elastic force of the spring of the connector box storage box.
[0032]
II) According to the second aspect of the present invention, even when the connector box is housed by being lowered from the upper side of the connector box storage box to the lower side in remote operation, Is corrected by the guide portion and guided to an accurate position, so that the connector box can be securely stored in the connector box storage box.
[0033]
III) According to the third aspect of the present invention, since the handle portion is provided on the upper end surface of the connector box, it can be gripped by the manipulator .
