Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a power meter mounting base for installing an integrated power meter installed inside or outside a building in electric wiring work in a building such as a general house or a high-rise building.

[0002]

[Prior art]

 Conventionally, as a mounting plate for mounting this type of integrated power meter, a wiring box with a front surface opened at the bottom of the mounting surface with a hollow back made of synthetic resin is provided, and a cavity at the back of the mounting surface penetrates the upper part of the mounting plate. There is a box mounting plate for an integrated power meter that has an electric wire insertion tube that reaches the hole (Jpn. 4182, Jpn. 4-1883).

[0003]

[Problems to be solved by the device]

 In the above conventional box mounting plate, when the wire from the outside is drawn in through the wire insertion tube on the back of the mounting surface or the wire from the indoor electric appliance, only the front of the lower wiring box is opened In the box, the wires must be pulled out and connected to the terminal fittings of the power meter, and because the wiring box is narrow, it is difficult to carry out the wiring work, and if the wires to be connected to the terminals are too long, the extra part is It was more inconvenient because it was hard to fit in the wire insertion tube. Therefore, when wiring work, there is a work to make the work easier by removing the bottom part of the wiring box.However, since the wires can only be taken out by the wiring box, it may be inconvenient for the connection work, and extra wires can be inserted into the wire insertion tube. This is a problem because it is difficult to store and the product is expensive due to the attachment / detachment structure on the bottom.

The present invention has an electric wire insertion passage opened on the front surface of a mounting surface made of synthetic resin, and when the electric wire is wired to the integrated electric power meter from outside or indoors, the electric wire is not only inserted in the wiring space but also on the mounting surface. It is intended to provide a mounting base for power meters that can be taken out of the passage and facilitate wiring work.

[0005]

[Means for Solving the Problems]

 The power meter mounting base of this invention has a mounting surface with a hollow back surface made of synthetic resin and a wiring space at the bottom, and has a concave wire insertion passage with a front opening on the mounting surface. It is integrally formed.

Further, the concave electric wire insertion passage is integrally formed from the wiring space on the mounting surface to the electric wire lead-in pipe on the upper part of the peripheral wall.

A cover plate is provided on the concave electric wire insertion passage or on the front surface thereof and the mounting surface so as to be freely opened and closed or detached, and the cover plate is opened or removed at the time of wiring work.

[0008]

[Action]

 According to this mounting base, wires are inserted into the integrated power meter from outside or indoors through the wire insertion passage provided on the mounting surface with a hollow back, and the wire is pulled out not only from the wiring space but also from the wire insertion passage. Connect to the terminal fittings of the integrated power meter attached to. If the electric wire connected to the terminal fitting is too long, the electric wire insertion path has an open front surface, so that the electric wire can be freely bent and stored in the electric wire insertion path.

[0009] When the cover plate is covered with the wire insertion path or its mounting surface so as to be freely opened and closed or detached, the cover plate is opened or removed during wiring work to open the front surface of the wire insertion path and become redundant. Bend the wire and store it in the wire insertion path, press it with the cover plate and connect it with the terminal fittings of the integrated power meter in the same manner as above, and attach the power meter to the mounting surface through the cover plate.

【Example】

 The embodiment shown in FIGS. 1 to 4 is a mounting base with a decorative cover made of synthetic resin, in which a raised mounting surface 1 is formed in the upper part of a housing 7 having a front opening with a back portion as a cavity 8, and A wide wiring space 2 is formed between the mounting surface 1 and the lower peripheral wall 4, and a wire lead-in pipe formed on the mounting surface 1 from the wiring space 2 between the upper portion of the peripheral wall 4 and the mounting surface 1. Up to 5 and 5, the electric wire insertion passages 3 and 3 having a concave front surface are integrally formed.

The electric wire insertion passage 3 has a U-shaped cross-section that substantially matches the electric wire B, and the bottom surface thereof is flush with the back wall of the wiring space 2 so that the electric wire can be inserted straight through. Further, a through hole 9 with a temporary lid is formed in the rear wall of the wiring space 2, and U-shaped grooved electric wire insertion holes 10 and 10 are formed in the lower peripheral wall 4 from the upper end thereof. The plug is inserted from the top. Further, an insertion hole 11 with a temporary lid is also provided inside the electric wire lead-in pipe 5 provided between the upper portion of the peripheral wall 4 and the mounting surface 1.

Reference numeral 12 is a screw mounting hole, 13 is a screw for hooking a hook of the power meter A, 14 is a long hole for mounting the power meter A, and 15 is a mounting hole for fixing the mounting base to the wall surface C. is there. Reference numeral 16 denotes a case-type makeup cover that has a window hole 17 in the upper portion and covers the casing 7. The attaching portion 18 at the lower portion of the cover is attached to the attaching portion 19 at the lower portion of the casing 7 to fit the upper portion. The joint portion 20 is fitted to the collar portion 21 on the upper portion of the housing 7 by using elasticity.

Another embodiment shown in FIG. 5 to FIG. 7 is a mounting base made of synthetic resin, in which a mounting face 1 having a cavity 8 at the back is formed on the upper part of the plate 7 ′, and a front face is formed on the lower part thereof. A wiring box 2 having an opening is integrally formed, and its mounting surface 1 is a front surface from the wiring box 2 to the wire lead-in pipes 5 ', 5'formed between the upper portion of the peripheral wall 4 and the mounting surface 1 as in the above embodiment. The electric wire insertion passages 3 are formed integrally with each other by forming an opening. As in the previous embodiment, the mounting surface 1 is provided with a mounting long hole 14 for the power meter A, a mounting mounting hole 15 is provided around the mounting base, and an insertion hole 11 with a temporary lid is provided in the wire lead-in pipe 5.
