In addition, an incoming line port 8 which opens toward the cover 3 side is provided through a sidewall 7 of the base 2 and a projection section 20 which can be inserted into the port 8 is provided through the cover 3 corresponding to the wire lead-in port 8.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to an implantable electric device.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 4 and 5, an embedded type electric device 1 comprises a base 2 embedded in a wall surface and a cover 3 exposed from the wall surface. The base 2 has a bottomed box shape and has an open front surface, a flange portion 4 at an open portion, and a box portion 5 at a rear portion. Then, the box portion 5 of the base 2 is embedded in the wall surface. An inlet 8 is provided in the upper side wall 7 among the side walls 6 forming the box portion 5, and a plurality of wirings 9 from the inner surface of the wall are taken into the base 2 and connected to the terminals 10 in the base 2.

[0003]

In the above-mentioned prior art, if the number of wires increases when the wires 9 are connected to the terminals 10 after the wires 9 are passed through the input port 7, when the wires are connected to each other, the wires 9 are not connected to each other. Since the wiring 9 hinders the movement of the wiring 9 freely, it is difficult to connect the terminal 10 to the terminal 10.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide an embedded electric device in which wiring taken in from a wall surface can be easily connected. .

[0005]

According to an aspect of the present invention, there is provided an implantable electrical apparatus comprising a base embedded in a wall and a cover attached to the base. The base has a bottomed box shape, an open front surface, and a terminal for connecting wiring from the inside of the wall is provided in the base, and an input port opened toward the cover side is provided on a side wall of the base. The cover corresponding to the entrance is provided with a protruding portion that can be inserted into the entrance.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. 1 is a top view of the embedded electric device, FIG. 2 is a cross-sectional view of the embedded electric device taken along line BB, and FIG. 3 is a perspective view of a base.

[0007] As shown in FIGS. 1 to 3, an embedded electric device 1 is composed of a base 2 embedded in a wall surface and a cover 3 mounted in an exposed state from the wall surface. The base 2 has a bottomed box shape and an open front surface, and has a flange 4 extending outward from the open portion. The bottomed box-shaped portion is a box portion 5. And this box part 5 is embedded in the wall surface. Four side walls 6 forming the box portion 5
Of these, the entrance 8 is formed in the side wall 7 on the upper surface side.
The input port 8 takes in a plurality of wirings 9 drawn from the inside of the wall into the base 2 and
It is provided to connect to.

A screw 13 provided on the flange portion 4 of the base 2 is provided to be screwed to a reinforcing building material or the like (not shown) provided on the wall surface or on the inner edge of the wall opening. The printed board 14 is disposed on the bottom plate 21 of the base 2. The terminal 10 is provided on the left end side of the printed circuit board 14.

On the other hand, the cover 3 comprises a box 11 and a flange 1
And a base 2 with a hook or a set screw (not shown).
It is configured so that it can be attached to.

The entrance 8 provided in the side wall 7 on the upper surface side of the box portion 5 is formed such that a portion corresponding to the entrance 8 is open from the side wall 7 to the flange 4.

On the other hand, a projecting portion 20 to be inserted into the inlet 8 is formed integrally with the cover 3 on the side of the cover 3 corresponding to the inlet 8. The width of the protrusion 20 is the same as that of the entrance 8.
The length is formed substantially the same as the width of the wire 9, and the length is determined in consideration of the expected number of wires 9 and the wire diameter when the wire is inserted into the inlet 8.
The length of the wiring 9 is set so that the wiring 9 can be appropriately pressed.

Next, a connection construction method will be described. Although not shown, an opening equivalent to the base 2 is provided on the wall surface,
A plurality of wires 9 are formed in this opening. Next, the wiring 9 is inserted into the inlet 8 from the opening of the inlet 8 of the base 2, the base 2 is embedded and fixed in the wall opening, and the screw 1 is fixed.
Attach to the wall with 3. Then, the wiring 9 is connected to the terminal 10.

According to this method, since the input port 8 is open, the wiring 9 can be easily inserted, and when connecting to the terminal 10, the input port 8 is open over the entire depth of the side wall 7. Therefore, even if the number of the wirings 9 is large to some extent, the wirings 9 have a degree of freedom of movement, and the wirings 9 can be routed at the time of connection, and the connection is easy.

After connecting the wiring 9 to the terminal 10, while holding the wiring 9 with the tip 22 of the projecting portion 20 of the cover 3,
The protrusion 20 is inserted into the wire inlet 8, and the cover 3 is attached to the base 2.

[0015]

According to the first aspect of the present invention, unlike the prior art, there is no need to insert a wire into the inlet, and the wiring work is easy because the wiring has a degree of freedom when connecting. This has the effect.
