  In this configuration, the connection work is performed with the front cover of the inverter open. Use a screwdriver to tighten the terminal block screws. At the time of this work, it is conceivable that the equipment of the power conditioner composed of the electronic component and the electronic board is accidentally damaged or damaged by this tool.

  In addition, the power and signal line wiring paths connected to the inverter equipment are often concealed in the mounting surface, and with the power and signal lines drawn out from the opening on the mounting surface, This is a difficult task of hooking a housing for storing 20 kg of power conditioner equipment onto the mounting plate while preventing power and signal lines drawn from the mounting surface.

  The present invention has been made in view of the above, and does not damage the electronic components and the electronic substrate during the mounting operation, and facilitates fixing of the housing for housing the power conditioner devices. With the goal.

  The present invention has been made to solve the above-described problems, and includes a housing that accommodates a power conditioner device, a mounting plate that holds the housing from the rear of the housing, and the housing Is provided with a connection connector that enables electrical connection toward the rear, and a connector that is connected to the connection connector and an electric wire that needs to be electrically connected to the device are fixed to the mounting plate. And a connection terminal that is connected.

  According to the present invention, it is possible to easily attach the casing for housing the equipment of the power conditioner to the wall surface without damaging the electronic components and the electronic substrate during the attaching operation.

It is explanatory drawing which shows the housing | casing for power conditioners. It is explanatory drawing of the attachment plate which fixes a housing | casing and a housing | casing. It is explanatory drawing of the state which removed the door body from the housing | casing. It is a rear view of a housing | casing. It is explanatory drawing seen from the inner side of the door body. It is explanatory drawing of an attachment board. It is explanatory drawing which connected the electric wire to the attachment board.

  Hereinafter, embodiments of a casing for a power conditioner according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is an explanatory diagram showing a casing for a power conditioner. FIG. 2 is an explanatory diagram of a housing and a mounting plate for fixing the housing. FIG. 3 is an explanatory diagram of a state in which the door is removed from the housing. FIG. 4 is a rear view of the housing. FIG. 5 is an explanatory diagram viewed from the inside of the door body. FIG. 6 is an explanatory diagram of the mounting plate. FIG. 7 is an explanatory diagram in which an electric wire is connected to a mounting plate. Reference numeral 1 denotes a casing for a power conditioner, 2 denotes a mounting plate, the mounting plate 2 is fixed to a wall surface, and the casing 1 is fixed to the fixed mounting plate 2. Is fixed to the wall surface.

  The housing 1 includes a lid 4 and a box 3, and the box 3 includes a back plate 3d, a top plate 3b, a bottom plate 3c, and side plates 3a, and the side plates 3a and bottom plates 3c on both sides are integrally formed in a U shape. Is formed. 3e is an opening part of the box 3, and is a part facing the back plate 3d. Further, the back plate 3d is provided with an opening 3f, and a connection connector 6 for electrically connecting to a later-described electric wire 7 to a power conditioner device 34 is provided facing backward.

  The inverter 34 is stored in the box 3.

  As shown in FIG. 5, the lid 4 is formed in a box shape using a metallic material such as a steel plate or a material such as a synthetic resin, and closes the opening 3 e of the box 3.

  The attachment plate 2 held on the back plate 3 d side of the housing 1 is provided with a terminal connection base 5 for relaying electric wires (power lines and signal wires) 7 and connecting them to the equipment 34 in the housing 1.

  The terminal connection base 5 is provided with a connector 5a for electrically connecting the electric wire 7 to a connection terminal 5b for electrically connecting the electric wire 7 and a connection connector 6 provided for the device 34. This connector 5a is structured to be freely connectable to the connection connector 6 provided on the back plate 3a side on the device 34 side, and when the housing 1 is fixed to the mounting plate 2, the connector 5a and the connection connector 6 are automatically engaged. In addition, the electric wire 7 and the device 34 are electrically connected via the connection terminal 5b, the connector 5a, and the connection connector 6.

  Next, attachment will be described in detail.

  The mounting plate 2 is fixed to the wall surface. Fixing is fixed using screws or the like.

  After the attachment, the electric wire 7 is passed through the hole 2d of the attachment plate 2 to the terminal connection base 5 side, the terminal 8 is caulked at the tip of the electric wire 7, and fixed to the connection terminal 5b with a screw or the like.

  Next, the raised protrusions 2b and 2c provided on the four sides of the mounting plate 2 serve as positioning of the housing 1, and the back plate 3d side of the housing 1 is positioned so that the protrusions 2b and 2c are outside the housing 1. Is fixed to the mounting plate 2 so that the housing 1 is held by the mounting plate 2. When fixed, the connector 5a on the mounting plate 2 side and the connection connector 6 on the housing 1 side are engaged. After the engagement, the housing 1 is held by the convex portions 2b and 2c, so the connector 5a and the connection connector 6 No stress is applied to the connecting portion.

  After fixing the housing 1 to the mounting plate 2, the housing 1 is securely fixed to the mounting plate 2 by fixing the housing 1 and the convex portions 2 b and 2 c with screws or the like.

  When connecting the electric wires (power and signal lines) 7 connected to the inverter, it can be processed with only the mounting plate 2 not equipped with the equipment 34, so it is light without worrying about damage to electronic components. Good handling.

  Further, since the attachment is completed without having to open the lid 4 of the housing 1, there is no fear that the device 34 is accidentally damaged by the work.

  The power conditioner housing according to the present invention is useful for improving ease of attachment and certainty, and is particularly suitable for improving ease of attachment.
