Japanese Utility Model Publication No. 62-14619

  However, if the breaker unit and the outlet plug unit are combined into a breaker unit and an outlet unit and combined to the left and right in order to improve productivity, the width of the breaker unit is increased. When the power terminal is provided, there is a problem that the width of the case becomes large.

  The present invention includes an outlet unit including at least one or more insertion plug connection portions, a power supply terminal for connecting a power supply line, and a shut-off mechanism portion for cutting off power supply to the insertion plug connection portion. In an embedded outlet formed in the size of three modules that are fixed to the mounting frame of a large-angle continuous wiring device standardized by JIS standards by combining breaker units on the left and right, and perpendicular to the width direction of the breaker unit The power supply terminals are provided in approximately one row in the direction.

  According to the present invention, there is an effect that the breaker unit can be thinned.

  A breaker unit having at least one outlet unit having at least one insertion plug connecting portion, a power supply terminal for connecting a power line, and a shut-off mechanism portion for cutting off power supply to the insertion plug connecting portion. In an embedded outlet formed in a three-module size that is fixed to the mounting frame of a large-angle continuous wiring device standardized in accordance with JIS standards, there are a plurality of components in the direction orthogonal to the width direction of the breaker unit. The power supply terminals are provided in approximately one row.

  A first embodiment of an outlet according to the present invention will be described with reference to the accompanying drawings of FIGS.

  The outlet 1 has a mounting frame (JIS C 8375-1992) 2 of a large-angle continuous wiring apparatus standardized by the JIS standard (Japanese Industrial Standard), and three module dimensions (JIS) that can be mounted on the mounting frame by combining left and right. C 8303 to 1993), and the outlet unit 3 and the breaker unit 4 are formed.

  The outlet unit 3 includes a plurality of insertion plug connection portions 11 to which plug blades (not shown) of insertion plugs of a load device are connected to a box-shaped case 10. A pair of receiving blades 11a, 11a housed inside, and plug insertion ports 11b, 11b formed on the front surface of the case 10 facing the receiving blades 11a, 11a for inserting plug blades of plugs It is composed. Further, a detection unit 13 for detecting tracking generated between the plug blades of the insertion plug, and a printed circuit board 14 on which an abnormality detection circuit for detecting an abnormality by a signal from the detection unit 13 and outputting a shut-off signal is mounted, The detection unit 13 is provided between the receiving blades 11a and 11a, the detection hole 10a is formed in the case 10 facing the detection unit 13, and the printed circuit board 14 is stored in the back space of the receiving blades 11a and 11a. Yes. The interruption signal output from the abnormality detection circuit is transmitted to the breaker unit 4 via a signal line 16 extending from the back surface of the case 10. The outlet unit 3 only needs to include at least one plug-in connection portion 11, and other wiring devices such as the ground terminal 17 may be combined, and the combination can be changed as appropriate.

  In addition, the breaker unit 4 stores therein a shut-off mechanism part 19 that opens an open / close contact (not shown) and shuts off the electric circuit when receiving a shut-off signal inside the box-shaped case 18, and opens and closes the shut-off mechanism part 19 on the front surface. An operation handle 20 for opening and closing the contact is provided so that it can be turned up and down, and four plug-in type power terminals 21 for connecting the power line 25 to the back surface are provided in a substantially line in the width direction of the case 18. In FIG. 2, the power supply terminal 21 is integrally formed with the upper two and the lower two so that power lines 25 having different polarities are connected to each other. A release portion 22 is provided for releasing the connection of the power supply line 25 connected to the power supply terminal 21 by inserting the tool 26. The power supply terminal 21 is assembled symmetrically on both sides of an insertion hole 21a formed in the case 18, a substantially E-shaped terminal board 21b connected to the electric circuit, and an E-shaped central piece 21ba of the terminal board 21b. The lock spring 21c is composed of a substantially S-shaped pressing piece 21ca that presses the wire 25 against the outer piece 21bb of the terminal plate 21b and a locking piece 21cb that is locked so that the electric wire is not pulled out. The release portion 22 includes a long release hole 22a formed in the case 18, and a substantially U-shaped release member 22b provided so as to be movable back and forth in the insertion / removal direction of the power line 25. In order to connect the power supply line 25 to the power supply terminal 21, the power supply line 25 is simply inserted into the insertion hole 21 a of the power supply terminal 21, and the locking piece 21 cb of the locking spring 21 c does not come out by biting into the power supply line 25. Thus, the pressing piece 21ca is electrically connected by pressing the power supply line 25 against the terminal plate 21b. In order to pull out the power line 25 from the power terminal 21, as shown in FIG. 4, a jig 26 is inserted into the release hole 22a of the release part 22, and the release member 22b is pushed into the case 18, whereby the leg part 22ba of the release member 22b. Presses and deforms the locking piece 21cb of the locking spring 21c to release the locking, so that the power line 25 can be removed. Further, a flexible conductive wire 23 extending from the back surface of the case 18 is connected to the outlet unit 3 so as to supply power to each plug-in connector 11 and the printed board 14.

  The outlet unit 3 and the breaker unit 4 are combined to the left and right by an engaging means (not shown), and the front part of these units is fitted into the opening 2a of the mounting frame 2 and then fixed by fixing means such as screws or caulking. Is done. Then, the mounting hole 2b of the mounting frame 2 is screwed into a switch box (not shown) embedded in the wall surface with a mounting screw (not shown), and the flash plate 9 is mounted on the front surface of the mounting frame 2 and installed. The

  The outlet 1 thus installed is used with the operation handle 20 of the breaker unit 4 turned on. When tracking occurs, the detection unit 13 detects through the detection hole 10a of the outlet unit 3, and an abnormality is detected by the detection signal of the detection unit 13. When it is determined that the detection circuit is tracking, a break signal is output to the breaker unit 4 via the signal line 16, and the break mechanism unit 19 of the breaker unit 4 is activated when the break signal is received to break the electric circuit, and the operation handle 20 Is supposed to turn off.

  In this embodiment, the electric circuit is cut off by detecting tracking. However, the electric circuit may be cut off by detecting overload, electric leakage, cord short circuit, earthquake, or the like. Further, the connection method between the breaker unit 4 and the outlet unit 3 is not limited, for example, by connector connection, and the breaker unit 4 and the outlet unit 3 are made of a resin storage case as shown in FIG. It may be formed so as to be housed in 30 and attached to the mounting frame 2, and the shape and structure of the outlet can be changed as appropriate without departing from the spirit of the present invention.

The outlet socket which concerns on this invention is shown, (a) is a front view, (b) is a rear view, (c) is a bottom view. It is a rear view which shows the breaker unit of the outlet socket which concerns on this invention. It is the sectional view on the AA line of FIG. It is explanatory drawing which shows a mode that an electric wire is extracted from a power supply terminal. It is a front view of the state which attached the flash plate to the outlet socket which concerns on this invention. It is a cross-sectional view showing a modified embodiment of the outlet according to the present invention.
