Description

[Detailed explanation of the idea] The present invention relates to an outlet adapter.

For example, a conventional outlet adapter with a built-in receiver for a carrier wave device that controls multiple loads using a control signal superimposed on a power line has a case body 13, as shown in FIG.
The plug part and the outlet part are separately provided on the base body 12 constituting the lid body 11, and the plug part and the outlet part are connected within the base body 12 by the cord 14, so that the cord 14 is connected to the base body 12. In order to connect to the printed board 9 placed in the printed circuit board 12, the cord 14 has to be pulled around, and there are many connection points of the cord 14, which makes assembly difficult, and the influence of induced noise coming from the power source and the cord 14 can cause problems in the printed circuit board. The disadvantage is that the electronic circuit constituting the receiver provided on the plate 9 is easily damaged, and the electronic circuit is therefore prone to malfunction.

The present invention has been proposed in view of the above points, and aims to provide an outlet adapter that reduces malfunctions of the built-in electronic circuit and is easy to assemble.

Embodiments of the present invention will be described in detail below with reference to the drawings.

3 in the figure is a connector unit, and this connector unit 3 has an outlet 1 on the front for inserting a plug, and this outlet 1
A blade receiving spring 16 is installed inside at a position corresponding to the power outlet to constitute the outlet part, and two plug blades 2, 2 to be inserted into the power outlet are provided on the rear side to constitute the plug part. It is integrated with the following.

Furthermore, as shown in FIG. 4, a terminal 17 is provided at the base of the plug blade 2 on one side of the connector unit 3, and a terminal 17 is also provided at the base of the blade receiving spring 16 corresponding to this terminal 17.

Reference numeral 6 denotes a case body, and this case body 6 includes a box-shaped lid 4 with a box-shaped opening on one side and a box-shaped opening on one side with holes drilled in the front for inserting the switch 18 and the display element 19, and a box-shaped opening on one side with holes at the bottom of the surface. The base body 5 has a protrusion 20 having a substantially U-shaped cross section for positioning when the case body 6 is attached to an outlet 25 provided on a wall 15. The front opening is covered with the lid body 4 and it is very popular.

Reference numeral 9 denotes a printed board, and to this printed board 9, electronic circuits and mechanical parts for controlling the power supply via the connector unit 3 are attached.

In this embodiment, an IC 7 such as an LSI having a microcomputer function that is easily affected by induced noise is used as the first IC.
A second printed board 21 is attached to the second printed board 22, and mechanical parts such as a relay 8 that are less susceptible to induced noise are attached to the second printed board 22.

Thus, the connector unit 3 is housed in the upper part of the case body 6.

At this time, the plug blade 2 side of the connector unit 3 is fitted into the hole opened on the back surface of the base body 5 to make the plug blade 2 protrude from the back surface of the base body 5 of the case body 6, and the plug blade 2 side of the connector unit 3 is inserted into the hole opened on the back surface of the base body 5, and the plug blade 2 side is inserted into the front surface of the lid body 4. An insertion port 1 is placed on the front surface of the lid body 4 by fitting into a hole opened in the hole.

When arranging the first and second printed boards 21 and 22,
Mechanical components such as the relay 8 are arranged above, that is, directly below the connector unit 3, and electronic circuits such as the IC 7 are arranged below, that is, separated from the connector unit 3.

In other words, a printed board 9 (i.e., 21, 22
) with the other side facing upward.

Furthermore, a cord 14 is connected from both terminals 17, 17 of the connector unit to a connection point in the immediate vicinity of the second printed circuit board 22.

When attaching the lid 4 to the base 5, the locking portions 23 and 23, which are recesses each having a substantially U-shaped cross section, provided at the lower side ends of the lid 4 and the base 5 are fitted into each other. In addition, screws 1 are inserted into the recesses provided for fixing the connector unit 3 with the screws 10 on both sides of the connector unit 3 housed in the upper part of the case body 6.
0 is inserted, and the lid body 4 and the base body 5 are securely held and fixed by this screw 10.

In addition, a rib 26 protruding inward approximately at the center of the lid body 4
Press the second printed board 22 with
2 more reliably.

When this outlet adapter is inserted into the outlet 25 on the wall 15, it can be attached parallel to the wall 15 as shown in FIG. 2 because of the protrusion 20 provided at the bottom of the case body 6.

Incidentally, as an example using this embodiment, as shown in FIG. 5, the power plug of the television T is inserted into the outlet 25.

On the other hand, by operating the carrier wave transmitter A connected to another outlet 25, a control signal is transmitted to the outlet adapter, which is a receiver, and the power of, for example, the television T is turned on and off using this control signal.

As mentioned above, in this invention, the connector unit is housed in the upper part of the case body, and the electronic circuits such as ICs are attached below the printed circuit board, so the connection cord can be shortened and the induced noise from the connector unit can be reduced. It is possible to reduce the influence of
In addition, the connector unit is housed in the upper part of the case body, and a plug socket is provided and a plug blade is protruded from the rear surface to form an integrated plug outlet, so it can be integrated into the case body. Assembly is easy as all you have to do is insert and hold the plug, and the plug socket is in a horizontal position for stable use.Furthermore, the plug can be screwed into the position corresponding to the connector unit housed in the upper part of the case body. Since the lid and the base are screwed together, it has the advantage that it will not break even if excessive force is applied when attaching or detaching the plug or stopper blade.
