Description

  The present invention relates to a power distribution device with a connection converter that is used by being incorporated in an electrical device storage box such as a distribution board.

  In the distribution board, distribution equipment related to distribution from the distribution board may be incorporated in the vicinity of main breakers and branch breakers which are main components. Recently, a seismoscope has been regarded as important as a kind of such wiring equipment. This corresponds to the plug-in distribution board that has become the mainstream recently, and is used by plug-in connection to the bus bar like a branch breaker. The breaker can be shielded.

  However, a plug-in type seismograph for a distribution board could not be installed in the conventional screw terminal type distribution board. Moreover, even if the distribution board is a plug-in type, the plug-in type seismograph for the distribution board could not be incorporated even when all the branch lines were occupied by the branch breakers.

  Patent Document 1 discloses a conversion device that converts a power connection portion of a plug-in breaker into a screw terminal. However, since the converter of Patent Document 1 has a structure in which the screw terminal is operated from the side surface direction of the breaker, there is a problem that wiring workability inside the distribution board where the devices are densely packed is poor. Moreover, although the seismic device for distribution boards is provided with the signal wire | line for control, since the converter of patent document 1 is not conscious of a seismic device, consideration about the connection of a signal wire | line is not made | formed.

Figure 1 is a perspective view showing a connection converter with power distribution equipment in the first reference embodiment, FIG. 2 is an exploded perspective view thereof. In the figure, 1 is a power distribution device, 2 is a connection converter, and the power distribution device 1 is a seismograph for a distribution board. This seismograph for distribution board has a built-in seismic sensor (not shown) and its control board inside the housing 3, and when the seismic sensor detects a shake exceeding a predetermined seismic intensity, Is output to shut off the main breaker of the distribution board. Although the method of this interruption is not necessarily specified, most of the main breakers are earth leakage breakers equipped with an earth leakage detection function. Can be adopted.

  The housing 3 of the distribution panel seismic device, which is the power distribution device 1, has a width that is a multiple of the single-pole branch breaker used in the distribution panel so that the seismic sensor can be housed inside. In the embodiment, the width is doubled. As shown in FIGS. 2 and 3, the power source side of the housing 3 is provided with two plug terminals 4 similar to the plug-in branch breaker so that power can be supplied to the seismic sensor and the control board. It has become. For this reason, when the distribution board is of the plug-in type, the plug terminal 4 of the distribution board seismic device can be directly connected to the stacked bus bar. The connection converter 2 is connected to the power supply side so that it can be incorporated into all electrical equipment storage boxes such as non-plug-in distribution boards and connection boards other than distribution boards.

  The connection converter 2 has the same width as the casing 3 of the distribution board seismic sensor, and two power supply line connection terminals are accommodated therein. The power line connecting terminal of this embodiment is a screw terminal 5, which can be connected by rotating the screw 6 from the front side of the distribution board, that is, the upper surface side of FIGS. Reference numeral 7 denotes a protective cover which is removed during wiring work.

  As shown in FIGS. 4 and 5, two conductive bars 8 and 9 inserted into the two-stage plug terminals 4 of the power distribution device 1 are provided on the opposite side of the connection converter 2. The conductive bars 8 and 9 are formed by bending a copper bar into a U shape, and the lower piece is fixed to the screw terminal 5 with a rivet or the like. The vertical sides have different lengths, and the upper pieces overhang at different heights. Therefore, the two-stage plug terminals 4 of the distribution board seismic device can be plug-in connected to these conductive bars 8 and 9. In addition to this, a conductive bar and a screw terminal may be integrally formed.

  As shown in FIGS. 6 and 7, one conductive bar 8 is fixed at a fixed position, and the other conductive bar 9 is turned upside down so as to be attached to a two-stage plug for a distribution board seismic device. The connection position of the terminal 4 can be changed. In FIG. 6, the right conductive bar is turned upside down, and in FIG. 7, the left conductive bar is turned upside down.

  The distribution device with a connection converter configured in this way is connected to the screw terminal 5 of the connection converter 2 by screw connection of the power line to the segregator for the distribution board as the distribution device 1 in a non-plug-in type. It can be built into a distribution board. In addition, if the plug-in distribution panel does not have enough space for the plug-in distribution board, a seismic device for the distribution panel can be incorporated into the distribution panel. In addition, since the power supply lines of both poles can be connected from the front side of the distribution board, which is an electric equipment storage box, there is an advantage that the wiring workability is excellent.
