る。Next, the operation of connecting the ground wire 60 to the ground connection portion 50 will be described with reference to FIG. First,
FIG. 5A shows a state before the ground wire 60 is connected. The release lever 54 that is in contact with the curved portion of the lock spring 53 is pushed toward the cover 1b by the restoring force of the lock spring 53. The neck portion of the contact portion 54b hits the inner peripheral edge of the operation hole 55 of the cover 1b, and the release lever 54 is stopped at the reference position. At this time, the tip end portion 53a of the lock spring 53 attached to the terminal piece 52 is locked to the upper end edge of the locking hole 53b on the other end side. From this state, the tip of a tool such as a driver is inserted into the operation hole 55, the release lever 54 is pushed, and the ground wire 60 is inserted into the ground wire insertion port 51. That is, as shown in FIG. 5B, by pushing the release lever 54, the contact portion 54 of the release lever 54 is pressed.
The curved portion of the lock spring 53 moves toward the terminal piece 52 along the inclined surface of b, and accordingly, the tip end portion 53a has the locking hole 53b.
The engaging hole 54b comes to face the tip portion of the ground wire 60 inserted from the ground wire insertion port 55 apart from the upper edge of the ground wire. Therefore, if the ground wire 60 is inserted further into the back, the tip portion of the ground wire 60 is inserted into the locking hole 53b of the lock spring 53, and if the pushing operation of the release lever 54 is stopped, the release lever of the lock spring 53 restores the release lever. 54 is pushed back toward the cover 1b. At this time, the tip portion of the lock spring 53 where the locking hole 53b is provided is the terminal piece 52 and the tip portion 53a.
And the ground wire 60 is sandwiched between the upper end edge of the locking hole 53b and the terminal piece 52. It should be noted that the tip portion of the terminal piece 52 rises toward the ground wire 60 and bites into the ground wire 60 to prevent the claw portion 52a from coming off.
Is bent. Thus, the ground wire 60 is the terminal piece 5
The ground wire 60 and the terminal piece 52 are electrically and mechanically connected to each other by being sandwiched between the terminal 2 and the lock spring 53.

る。On the other hand, when the ground wire 60 is removed, the same operation may be performed, and the release lever 54 can be removed with a tool such as a screwdriver.
By pushing inwardly, the upper end edge of the locking hole 53b of the lock spring 53 is moved upward, and the force of the lock spring 53 holding the ground wire 60 is released, whereby the ground wire 60 can be pulled out. As described above, according to this embodiment, instead of the conventional screwdriver or manual screw type terminal (earth terminal), the quick connection terminal structure capable of connecting the earth wire 60 with one touch is provided in the earth connection portion 50. By adopting it, the work of connecting the ground wire 60 is facilitated and the workability is improved, and it is possible to reliably connect not only an ordinary single wire but also the ground wire 60 composed of a reed wire, and furthermore, the housing 1 Since a large part such as a terminal screw does not project on the front surface, the limited space can be effectively used. In addition, the operating portion 5 of the release lever 54
Since the front surface 4a does not project to the front side of the housing 1, the front surface of the housing 1 can be made substantially flat, and further, the pair of ground blade receiving springs 31, 31 and the terminal pieces 52, 52 of the ground connection portion 50 can be provided. Is integrally formed as the ground blade receiving spring block 30, there is an advantage that space can be saved and the number of parts can be reduced. In addition, a plug with a ground electrode can be connected, and two ground wire connecting portions 50,
Since 50 is provided, it is possible to surely ground the earth at both the ground electrode and the ground wire of the plug, and safety can be improved. In the case of a conventional screw-type ground connection consisting of a washer and a terminal screw, when the solid wire and the tie wire are connected at the same time, the tie wire cannot be firmly fixed and easily comes off. However, according to the present embodiment, the lock wire 53 can reliably and reliably hold the single wire and the base wire, and there is an advantage that the above problems do not occur. Further, it can be easily attached to an embedding box or the like in the same manner as the existing embedding-type wiring device, and the construction work can be simplified and parts can be shared.

51 is provided, and operation holes 55, 55 are provided at both corners on the front surface of the housing 1. In such an arrangement, a ground wire is inserted when a large one such as a so-called AC adapter is connected. The mouths 51, 51 may be blocked. Therefore, as shown in FIG. 6, the operation holes 55, 55 are arranged closer to the plug blade insertion opening 4c, and the ground wire insertion openings 51, 51 are arranged at the front end (lower end) of the housing 1 and the plug is inserted. By taking a long distance from the blade insertion ports 4a to 4c, it is possible to prevent the ground wire insertion ports 51, 51 from being blocked even when a large one such as an AC adapter is connected. The ground wire 60 can be connected simultaneously with the plug and the AC adapter.

に接続されることになる。Next, the operation of connecting the ground wire 60 to the ground connecting portion 50 'will be described with reference to FIG. First, FIG. 14A shows a state before connecting the ground wire 60. As described above, the release lever 58 which is in contact with the curved portion of the lock spring 57 by the restoring force of the lock spring 57 is shown in the figure. The release lever 58 is biased counterclockwise, the operating portion 57a hits the stoppers 9a, 9a provided in the recesses 9, 9, and the release lever 58 is stopped at the reference position. At this time, the tip portion 57 of the lock spring 57 attached to the terminal piece 52.
a is locked to the upper edge of the locking hole 57b on the other end side. From this state, a person manually covers the operation portion 58a with the cover 1b.
The release lever 58 is operated in a direction projecting from the front surface of (1) (clockwise rotating direction in the drawing), and the ground wire 60 is inserted into the ground wire insertion port 59. That is, FIG.
4 (b), by rotating the release lever 58, the contact portion 58b of the release lever 58 causes the lock spring 57 to move.
Is bent, the curved portion of the lock spring 57 moves toward the terminal piece 52, the tip 58a moves away from the upper edge of the locking hole 58b, and the locking hole 58b is inserted from the ground wire insertion port 59. It comes to face the front end portion of the grounded wire 60. Therefore, if the ground wire 60 is inserted further into the back, the tip portion of the ground wire 60 is inserted into the locking hole 57b of the lock spring 57, and if the release lever 58 is released, the release lever 58 is moved by the restoring force of the lock spring 57. It is rotated counterclockwise in the figure. At this time, the tip portion of the lock spring 57 where the locking hole 57b is provided is the terminal piece 52 and the tip portion 5.
7a, and the upper edge of the locking hole 57b and the terminal piece 52
The ground wire 60 will be sandwiched between and. Therefore,
Since the ground wire 60 is sandwiched between the terminal piece 52 and the lock spring 57, the ground wire 60 and the terminal piece 52 are electrically and mechanically connected.

By rotating the release lever 58 clockwise in the drawing, the upper end edge of the locking hole 57b of the lock spring 57 is moved downward. The ground wire 60 can be pulled out by releasing the force of the lock spring 57 that holds the ground wire 60. According to the present embodiment, similarly to the first embodiment, the work of connecting the ground wire 60 is simplified and the workability is improved, and the ground wire insertion ports 59, 59 are arranged in a predetermined direction from the normal direction of the front surface of the housing 1. Since it is provided in an oblique direction by inclining by an angle, the projecting position of the ground wire 60 can be moved to the lower end side of the housing 1 as compared with the second embodiment, so that it interferes with the ground wire 60 when connecting the plug. This has the advantage that it can be further reduced.
