Description

[Detailed Description of the Invention] The present invention relates to a waterproof wiring device such as an electrical outlet, and more particularly to a waterproof structure for an operating opening.

This type of waterproof wiring device, for example, is provided with an operating opening diagonally below an operating section into which a plug is inserted and connected, in an outlet, and this opening is covered with a lid.

However, in the past, the main body and lid were manufactured by integral molding, which meant that multiple types had to be manufactured according to different types of wiring devices, which had the disadvantage of being troublesome and expensive to manufacture. was made in consideration of the above-mentioned circumstances, and its purpose is to provide a waterproof wiring device with good waterproof performance by making the lid separate from the main body and covering the lid from the back side of the main body. do.

The present invention is to provide a downward operating opening in a protrusion in the housing section of the main body, cover this opening with a lid inserted through a wiring opening on the back side of the main body, and It is characterized in that it is fixed to a mounting part formed on the back side of the main body with a screw.

The details of the invention will be explained below with reference to the illustrated embodiments.

Reference numeral 1 denotes a wiring device main body made of electrically insulating synthetic resin, and the main body 1 includes a substantially rectangular plate portion 2 and a front surface inclined from above to below in the center of the plate portion 2. 3 and a protrusion 5 that bulges out to form a storage part 4 inside, and a downward operating opening 6 is formed on the lower surface of the protrusion 5.

Further, on the back side of the main body 1, a wiring opening 7 is formed opposite to the storage section 4.

Attachment portions 10 having attachment holes 9 penetrating from the front portion 3 to the back surface are formed above and below the wiring opening 7.

Further, an engagement groove 11 is formed in the inner lower end of the front surface 3 of the protrusion 5 in the horizontal direction and located inward from the opening edge 6a of the downward opening 6.

Furthermore, a mounting part 12 is formed in the housing part 4 and protrudes toward the wiring opening 7. A projection 13 is provided on the inner end surface of the mounting part 12, and a projection 13 is located below the projection 13. The screw hole 15 faces the wiring opening 7 on the inner end surface of the mounting portion 12.
is opened.

An insulating wall 16 is vertically formed integrally with the main body 1 to partition this storage section 4 from side to side. Receiving protrusions 17, 17 are provided on the upper side of the storage section 4 partitioned by this insulating wall 16 for wiring. The receiving protrusions 17, 17 have screw holes 18 formed in their inner end surfaces.

Furthermore, a pair of terminal tube protrusions 19 and 20 are provided spaced apart from each other to the left and right under the receiving protrusions 17117 and project toward the wiring opening 7, and the inner end surfaces of the outer receiving protrusions 19 and 19 are A locking protrusion 21 is provided in a protruding manner.

The main body 1 further includes the terminal receiving portion 19°2 in the storage portion 4.
A receiving protrusion 22 is formed between the two terminals 1 and 2 and lower than the terminal receiving part 17, and a screw hole 23 is formed in the inner end surface of the receiving protrusion 22.

24.24 is a terminal piece, a terminal screw 25 is fitted into this terminal 24.24, and one end is fixed with a mounting screw 26 that comes into contact with the receiving protrusion 17 and is screwed into the screw hole 18. It is now possible to do so.

Moreover, the receiving protrusions 19, 20 are provided on both sides of the terminal pieces 24, 24.
The protrusion 2 formed on one of the receiving protrusions 19 and 19
1 is positioned in a groove 27 formed in the outer edge of the terminal piece 24.24.

At the other end of the terminal pieces 24 and 24, a fixing piece 29 bent at right angles is brought into contact with the receiving protrusion 22 via a bent piece 28 bent at right angles. It is fixed with a mounting screw 30 screwed into a screw hole 23 of this receiving projection 22.

A blade holder 32 is fixed to a connecting piece 31 bent from one side edge of the fixed piece part 29 of the terminal piece 24, 24 toward the opening 6 opened on the lower side of the main body 1.

Further, a lead wire tightening piece 39 is screwed onto the terminal screw 26.

Reference numeral 33 denotes a lid, which is inserted through the opening 7 on the back side of the main body 1 and whose leading edge is engaged with the engagement groove 11 of the main body 1.

Engaging edges 34 that engage with the inner surface of the plate portion 2 of the main body 1 are formed on both sides of the inner end of the lid 33 .

Generally, a protruding piece 35 that comes into contact with the inner end surface of the receiving protrusion 12 is provided on the rear end side of the lid body 33, and this protruding piece 35
A groove 36 is formed in the groove 36, and the protrusion 13 is positioned within this groove 36.

In the past, the cover body 33 of the octopus was formed with a plug blade insertion notch 7 facing the plug blade receiver 32.

Next, the method of attaching the lid 33 of this embodiment will be explained. The lid 33 is inserted through the back opening 7 of the main body 1, the leading edge is engaged with the engagement groove 11, and the retaining piece is 34 is brought into contact with the inner surface of the plate part 2, the projecting piece part 35 is brought into contact with the receiving part 12, and the projection 13 is positioned within this groove 36.
The projecting piece 3 is fixed by screwing the fixing screw 38 into the screw hole 15 and tightening it.
5 is fixed to the receiving projection 12, and the lower opening 6 of the main body 1 is covered with the lid 33 on the inner side of the opening edge 6a.

In this state, the main body 1 is attached via a backing (not shown) to a mounting tool such as a switch box provided on the mounting surface using a screw inserted through the mounting hole 9 of the mounting portion 10.

Then, a plug blade is inserted through the plug blade insertion hole 37 of the lid body 33 located on the lower surface of the main body 1 and connected to the plug blade receiver 32.

In addition, although the electrical outlet was explained in the above embodiment,
The present invention is not limited to this, and can be applied to various waterproof wiring devices.

As detailed above, the present invention provides a downward operating opening in the protrusion that forms the housing section of the main body, and covers this opening with a lid inserted through the wiring opening on the back side of the main body. Moreover, since this lid body is fixed with a screw to the attachment part formed inside the protrusion facing the wiring opening of the main body, it is suitable for various uses such as for switches or outlets. In this case, only the cover body needs to be replaced according to the intended use, and the main body can be used in one hole, so waterproof wiring devices for different uses can be provided easily and at low cost.
