Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a grounded embedded receptacle provided with a ground terminal and used by being attached to construction materials.

Conventionally, this type of outlet was manufactured by combining the outlet (C) and the grounding terminal (2) into the through-hole opening of the mounting frame (A), and then prying the thin wall part (E) formed on the mounting frame (A) with a screwdriver Y, as shown in Figure 1. The conceiving terminal and the second horizontal hole of the grounding terminal are engaged with thin-walled parts and fixed to the mounting frame A. Therefore, the thin-walled portion E must be bent with a screwdriver Y, resulting in poor workability, and the thin-walled portion E is deformed protrudingly without providing a guide to fix the connector and the ground terminal 2, so the thin-walled portion H is When it rises and falls up and down, the electrical outlet and ground terminal 2 become unstable, which has the disadvantage of making it difficult to finish the work. This invention was made in view of the above circumstances, and its purpose is to combine an outlet and a grounding terminal, make it easy to work without having to fix it to a mounting frame, provide a good finish, and provide power to equipment. At the same time, to provide a grounded electrical outlet that can be easily grounded.

An embodiment of the present invention will be described below based on FIGS. 2 to 4,
I will explain. Reference numeral 1 designates a container, which includes a lid body 5 having a boss portion 4 that is fitted with a window hole 3 of a plate 2 to be attached to the front surface, a terminal device (not shown) for connecting a cape W, and a blade holder spring 6. A pair of recessed chambers 7 for housing, a U-shaped rear terminal plate 8, and a recessed chamber 13 for housing a grounding terminal device 12 consisting of a spring 11 having a locking piece 9 and a pressing piece 10 are formed. It is combined with the container body 14.

Two plug blade insertion holes 15 corresponding to the springs 6 are provided at the top of the boss portion 4, and the ground terminal device 12 is provided below.
Correspondingly, the ground wire W3 is screwed onto the exposed ground terminal plate 8.
A grounding terminal 16 consisting of a screw for connecting is provided.
Incidentally, the ground terminal 16 may be one using the spring 11 as described above. Reference numeral 17 denotes a partition wall, which protrudes between the full-blade insertion hole 15 and the ground terminal 16 to connect the ground wire W3 to the ground terminal 16 made of a screw.
A plug 18 that locks the core wire of the ground wire W3 that has been stripped too long and inserts it into the core wire and the blade receiver spring 6 or the blade receiver spring 6.
This prevents the plug blade 19 from coming into contact with the ground terminal 1.
6, the ground wire W3 is prevented from moving in the lateral direction, and the ground wire W3 can be reliably connected to the ground terminal 16.

The partition wall 17 may be made stronger by providing a step so that the ground terminal plate 8 of the ground terminal 16 is lower than the blade insertion hole 15. Reference numeral 20 denotes a mounting frame, in which protrusions 21 provided on both side walls of the container 1 are locked by strangling pieces 22, thereby fixing the container 1.

After connecting the wiring W and the grounding wire W2 as shown in FIG. 3, the container 1 is placed in the box 23 embedded in the construction material
Just by attaching the mounting frame 20 to which the is fixed and attaching the plate 2, it is possible to connect the plug 18 of equipment Z such as a washing machine or a microwave oven as shown in Fig. By connecting the ground wire W3 to the blade receiving spring 6 through the blade insertion hole 15 and connecting the ground wire W3 to the ground terminal 16', it becomes possible to ground the device Z at the same time as the power supply. As explained above, this invention has the spear blade insertion hole 15 corresponding to the blade receiving spring 6 and the ground terminal 16 corresponding to the ground terminal device 12 provided in the boss portion 4 of the container 1. By combining the grounding terminal 2, it is possible to obtain a grounded bonito outlet that is easy to work without fixing to the mounting frame A, has a good finish, and can easily be grounded at the same time as powering the equipment Z.

Also, a partition wall 17 is provided between the plug blade insertion hole 15 and the ground terminal 16.
This can prevent the tip of the core wire of the grounding wire W3 connected to the grounding terminal 16 from protruding into the vicinity of the plug blade insertion hole 15, and the tip of the core wire of the grounding wire W3 can be prevented from protruding into the vicinity of the plug blade insertion hole 15. This has the effect of reliably preventing a ground fault caused by accidental contact with the receiving spring 6 or the plug blade 19 of the plug 18.

In other words, even if the insulation coating of the ground wire W3 is stripped too much and the core wire becomes long and the tip protrudes to the side when connecting to the ground terminal 16, the partition wall 17 prevents the tip from reaching the outlet. Therefore, connect the ground wire W3 to the blade holder spring 6 of the outlet or the cypress blade 19 of the plug 18.
This has the effect of eliminating the risk of ground faults occurring due to contact with soil. Further, since the partition wall 17 is formed in a U-shape, it is possible to prevent the ground wire W3 from moving in the lateral direction. This has the effect that the connection of the ground wire W3 to the ground terminal 16 can be ensured and connection reliability can be improved.
