[0046] will refer to Figure 1A to Figure 2C A first embodiment of the present invention is described. The plug 1 according to this embodiment is, for example, detachably connected to a DC outlet 2 buried in a building surface such as a wall. Such as Figure 1B As shown, a plug connector for DC power is composed of a plug 1 and a DC socket 2 connected to the plug 1 to supply DC power thereto. Unless otherwise described, the upward, downward, left and right directions of the plug 1 are based on Figure 1A And limited. Figure 1A The surface of the paper in indicates the front side of plug 1.

[0047] Such as Figure 1A and Figure 1B Explain that the plug 1 includes a plug body 11 having a horizontally elongated rectangular hexahedron shape and a size that can be held by a user. The plug body 11 is made of thermoplastic synthetic resin. Two round bar-shaped plug pins 12 to which power from the DC outlet 2 is supplied protrude from the front surface (the surface facing th...

[0070] will refer to Figure 3A to Figure 3F A second embodiment of the present invention is described. The plug 1 of this embodiment is used for a plurality of supply voltages, and the shape of the surrounding wall 13 is partially changed depending on the kind of supply voltage. Except for the shape of the surrounding wall 13, the second embodiment is the same as the first embodiment. Therefore, the same components are designated by the same reference numerals, and redundant descriptions thereof will be omitted.

[0071] The plug 1 of this embodiment is used for four DC supply voltages (eg approximately 6V, 12V, 24V and 48V). Therefore, the shape of the surrounding wall 13 is partially changed depending on the kind of supply voltage.

[0072] Figure 3A to Figure 3D Front views of plugs 1 for 6V, 12V, 24V and 48V respectively are provided. In the plug 1 for 24V, the surrounding wall 13 has a substantially quadrangular shape viewed in the plug insertion direction (from th...

[0082] will see Figure 5A to Figure 6EA third embodiment of the present invention is described. In the second embodiment, the shape of the corner of the surrounding wall 13 is changed depending on the kind of supply voltage. However, in the third embodiment, depending on the kind of the power supply circuit serving as the power supply source, the shape of the surrounding wall 13 is partially changed by forming an extension part protruding from the surface of the surrounding wall 13 . Except for the shape of the surrounding wall 13, the third embodiment is the same as the second embodiment. Therefore, the same components are designated by the same reference numerals, and redundant descriptions thereof will be omitted.

[0083] Power supply circuits (for example, SELV circuits, ELV circuits, FELV circuits, and the like) serving as power supply sources are standardized in IEC standards. In the plug 1 for the SELV circuit, the extension portion 15 protrudes inwardly from the l...

Abstract

A plug, adapted to be connected to a direct current (DC) outlet for supplying a DC power thereto, includes a plurality of round bar-shaped plug pins which protrudes from a front surface of a plug main body, and a surrounding wall which protrudes from the front surface of the plug main body to surround the plug pins. The plug pins are adapted to be connected the pin-receiving pieces through pin insertion holes of the DC outlet and to be supplied with power from the DC outlet. The surrounding wall is adapted to be inserted into an insertion groove of the DC outlet which is formed around the pin- insertion holes. The surrounding wall is formed in a substantially quadrangular shape, viewed from a front side thereof. The plug pins are arranged along a reference surface corresponding to one inner surface of the surrounding wall and offset closer to the reference surface than to an inner surface opposite to the reference surface.

Description

technical field [0001] The present invention relates to a plug for connection to a direct current (DC) outlet. Background technique [0002] Conventionally, there are known a DC outlet for supplying DC power to a DC device (for example, a radio, a television, or the like) having a DC power source as a driving power source, and a plug detachably connected to the DC outlet (see, for example, Japanese Patent Application Publication No. H7-15835, paragraphs [0021] to [0023] and Fig. 1,) (JP7-15835A). [0003] The DC outlet of JP07-015835A includes: a main body housed in a switch box provided inside a wall; and a converter provided inside the main body to convert AC power into DC power. In addition, the DC outlet includes: an AC connection terminal provided on the rear side of the main body facing the switch box; and an outlet portion provided on the front side of the main body facing the interior of the room. A power line of an AC power supply installed inside the wall is conn...
