Japanese Unexamined Patent Publication No. 2008-152121

An object of the present invention is to provide an AC adapter holder with few restrictions on the installation location and mounting operation.

The AC adapter holder according to the present invention is an AC adapter holder for holding an AC adapter body having power cords on two surfaces facing each other in a predetermined direction, and is open on both sides in the predetermined direction. A pair of insertion ports are provided, and locking pieces that can be elastically deformed in a direction orthogonal to the predetermined direction are provided in the vicinity of both insertion ports, and the locking pieces are attached to the inserted adapter body. It has a locking claw that locks and prevents it from coming off.

According to the AC adapter holder having this configuration, the adapter body can be inserted through two insertion ports that open on opposite sides. That is, the adapter body can be inserted into the AC adapter holder from two directions. When the adapter body is inserted through the insertion slot, the locking piece elastically deforms in a direction orthogonal to a predetermined direction (orthogonal direction) and passes through the adapter body. When the adapter body passes through the locking piece, the locking piece automatically returns to its original position and state by its elastic restoring force. When the adapter body is inserted into the AC adapter holder, the adapter body is held between the locking claw of the locking piece on one insertion port side and the locking claw of the locking piece on the other insertion port side. By locking the adapter body with the locking claw of the locking piece on one insertion slot side, the adapter body is prevented from coming off from one insertion slot. Further, the adapter body is locked by the locking claw of the locking piece on the other insertion port side, so that the adapter body is prevented from coming off from the other insertion port. When the adapter body is pulled out from the AC adapter holder, the adapter body is pulled out or pushed out from one insertion slot or the other insertion slot. When the locking claw of the locking piece is strongly pushed by the adapter body when the adapter body is pulled out from the insertion slot, the locking piece elastically deforms in the orthogonal direction to allow the adapter body to pass through.

In particular, it is preferable that the slit is continuous over the entire length in the predetermined direction, a locking piece is provided next to the slit, and the locking piece extends along the predetermined direction. According to this configuration, the power cord of the AC adapter can be taken in and out from the slit when the adapter body is attached to the AC adapter holder or when the adapter body is removed from the AC adapter holder. Therefore, the adapter body can be easily attached and detached. Further, since the locking piece is extended along the predetermined direction next to the slit, the locking piece can be easily provided by using the slit, and the arm length of the locking piece can be easily increased. Can be secured.

Further, a base plate portion, an upper plate portion facing the base plate portion, and a pair of side plate portions connecting the base plate portion and the upper plate portion are provided, and a slit and a locking piece are provided in the upper plate portion. It is preferable that the base plate portion is formed with a through hole having a shape corresponding to the shape of the upper plate portion. According to this configuration, the base plate portion can be used as a mounting surface for other members such as a wall. For example, when the AC adapter holder is mounted on the wall with the base plate as the mounting surface, a slit and a locking piece are provided on the upper plate on the opposite side of the base plate, and the slit and the locking piece are separated from the wall. Therefore, the adapter body can be easily attached and detached. Further, since the base plate portion is formed with a through hole having a shape corresponding to the shape of the upper plate portion, the AC adapter holder can be easily formed by injection molding. At the time of injection molding, by setting the direction in which the base plate portion and the upper plate portion face each other as the mold opening / closing direction, a simple mold configuration (two-way punching) can be achieved, and the mold can be manufactured at low cost.

As described above, since the adapter body can be attached to and detached from the AC adapter holder from two directions, restrictions on the installation location and attachment operation of the AC adapter holder are reduced.

The upper surface 111 and the lower surface 112 face each other. The upper surface 111 and the lower surface 112 have a rectangular shape with a predetermined direction as the long side direction and a direction orthogonal to the long side direction as the short side direction. Hereinafter, the long side direction is the vertical direction, and the short side direction is the horizontal direction. Further, the direction in which the upper surface 111 and the lower surface 112 face each other is defined as the height direction. The four side surfaces 113, 114, 115, 116 are composed of a first side surface 113 and a second side surface 114 that face each other in the vertical direction, and a third side surface 115 and a fourth side surface 116 that face each other in the lateral direction. The upper surface 111 and the lower surface 112 are formed of a flat surface. Legs 117 are projected from the lower surface 112. The leg portion 117 is a small protrusion, for example, hemispherical. The legs 117 are arranged at the four corners of the lower surface 112. Chamfered portions 118 are provided at the boundary portions between the upper surface 111 and the four side surfaces 113, 114, 115, 116, and the lower surface 112 and the four side surfaces 113, 114, 115, 116, respectively.

The first power cord 120 is connected to the first side surface 113, and the second power cord 130 is connected to the second side surface 114. The first power cord 120 electrically connects the commercial power supply 200 and the adapter main body 110. The first power cord 120 includes a power plug 121 at one end thereof. The power plug 121 is inserted into the outlet of the commercial power supply 200. The outlet of the commercial power supply 200 is installed on the wall surface of the building, for example. The second end of the first power cord 120 is detachably connected to the first side surface 113 of the adapter body 110. A male connector (not shown) is provided on the first side surface 113 of the adapter main body 110. At the second end of the first power cord 120, a female connector 122 that is detachably connected to the male connector of the adapter body 110 is provided.

The second power cord 130 electrically connects the adapter main body 110 and other members that require DC power. The first end of the second power cord 130 is detachably connected to another member. A female connector 131 is provided at the first end of the second power cord 130. The second end of the second power cord 130 is non-detachably connected to the second side surface 114 of the adapter body 110. As shown in FIG. 18A, the first power cord 120 is connected to the central portion in the lateral direction of the adapter main body 110. The second power cord 130 is eccentrically connected to the third side surface 115 side of the adapter main body 110. However, the connection position of the first power cord 120 to the adapter main body 110 and the connection position of the second power cord 130 to the adapter main body 110 may be various.

Holders 1 are shown in FIGS. 1 to 9. The holder 1 has two insertion ports 2 into which the adapter main body 110 is inserted along the vertical direction. The two insertion openings 2 are open on opposite sides of each other. The holder 1 is a resin molded product and is formed by injection molding. The holder 1 is composed of one component.

The holder 1 has a square tube shape as a whole. The holder 1 includes a base plate portion 10, an upper plate portion 11, and a pair of left and right side plate portions 12. Note that FIG. 7 is a plan view showing only the upper plate portion 11. Further, FIG. 9 is a bottom view showing only the base plate portion 10. The base plate portion 10, the upper plate portion 11, and the pair of left and right side plate portions 12 are flat plates having substantially constant thickness. The thickness of the base plate portion 10, the thickness of the upper plate portion 11, and the thickness of the pair of left and right side plate portions 12 may be the same as or different from each other. The base plate portion 10 and the upper plate portion 11 face each other, and the pair of left and right side plate portions 12 face each other. The pair of left and right side plate portions 12 connect the base plate portion 10 and the upper plate portion 11. An insertion hole penetrating in a predetermined direction is formed inside the base plate portion 10, the upper plate portion 11, and the pair of left and right side plate portions 12. The openings at both ends of the insertion hole are the insertion openings 2.

The base plate portion 10 has a rectangular shape with the axial direction (predetermined direction) of the insertion hole as the long side direction. The long side direction of the base plate portion 10 is the vertical direction, and the short side direction is the horizontal direction. Further, the direction in which the base plate portion 10 and the upper plate portion 11 face each other is defined as the height direction. The surface of the base plate portion 10 on the upper plate portion 11 side is the front surface, and the surface on the opposite side is the back surface. The back surface of the base plate portion 10 serves as a mounting surface for mounting the holder 1 to another member such as a wall. The base plate portion 10 is formed with a screw hole 20 as an attachment portion for attaching the holder 1 to another member such as a wall. The holder 1 can be screwed to another member such as a wall by inserting a screw, specifically a countersunk screw, into the screw hole 20 from the surface of the base plate portion 10. A plurality of screw holes 20 are formed. The base plate portion 10 is larger than the upper plate portion 11. As shown in FIG. 2, when the holder 1 is viewed from the upper plate portion 11 side in a plan view, a screw hole 20 is formed in an exposed portion of the base plate portion 10 that does not overlap with the upper plate portion 11. For example, three screw holes 20 are formed in the vicinity of both ends in the vertical direction.

A through hole 21 is formed in the base plate portion 10. The through hole 21 is formed corresponding to the upper plate portion 11, and the shape of the through hole 21 corresponds to the shape of the upper plate portion 11. The through hole 21 is slightly larger than the upper plate portion 11. When the holder 1 is viewed from the back surface side of the base plate portion 10 as shown in FIG. 3, the entire upper plate portion 11 can be visually recognized through the through hole 21 of the base plate portion 10. Four through holes 21 are formed. The through hole 21 is substantially L-shaped. The side plate portion 12 rises substantially vertically from the side edge portion on the surface of the base plate portion 10. The vertical dimension of the side plate portion 12 is smaller than the vertical dimension of the base plate portion 10.

The upper plate portion 11 is parallel to the base plate portion 10. A vertical slit 30 is formed in the central portion of the upper plate portion 11 in the horizontal direction over the entire length of the upper plate portion 11 in the vertical direction. The vertical slit 30 is along the vertical direction. A horizontal slit 31 is formed in the central portion of the upper plate portion 11 in the vertical direction over the entire width of the upper plate portion 11. The lateral slit 31 is along the lateral direction. The vertical slit 30 and the horizontal slit 31 are orthogonal to each other. The horizontal slit 31 is wider than the vertical slit 30, but each width is arbitrary. By forming the vertical slit 30 and the horizontal slit 31 in the upper plate portion 11 in this way, the upper plate portion 11 is divided into four plate piece portions 32. The four plate sides are symmetrical in the vertical direction as well as in the horizontal direction. All four plate piece portions 32 have the same shape and are L-shaped. The four plate piece portions 32 are located directly above the four through holes 21 of the base plate portion 10. The size of the plate piece portion 32 is slightly smaller than the size of the through hole 21. As described above, the holder 1 has a symmetrical shape in the vertical direction and the horizontal direction in the plan view as shown in FIG.

A locking piece 33 is provided on the plate piece portion 32. One locking piece 33 is provided on each plate piece portion 32. The locking piece 33 is located next to the vertical slit 30. The locking piece 33 extends in the vertical direction. Locking pieces 33 are vertically extended from the pair of left and right plate piece portions 32 on one insertion port 2 side, and similarly from the pair of left and right plate piece portions 32 on the other insertion port 2 side. Each locking piece 33 extends in the vertical direction. Two locking pieces 33 are provided in the vicinity of one insertion port 2. The pair of left and right locking pieces 33 are formed parallel to each other on both sides of the vertical slit 30. The pair of locking pieces 33 located on one insertion port 2 side face the opposite side in the vertical direction with respect to the pair of locking pieces 33 located on the other insertion port 2 side.

The locking piece 33 has a base end portion on the central portion side in the vertical direction and a tip end portion on the end portion side in the vertical direction. All the locking pieces 33 have the same length and width as each other. A locking claw 34 for locking the adapter main body 110 is formed at the tip of the locking piece 33. The locking claw 34 projects toward the base plate portion 10 side. It is preferable that an inclined surface 35 is formed on the inner surface of the locking claw 34. The inclined surface 35 of the locking claw 34 preferably has an inclined angle corresponding to the chamfered portion 118 of the adapter main body 110. The locking piece 33 can be elastically deformed along the plate thickness direction, that is, the height direction due to the holding elasticity of the resin constituting the holder 1. The base end portion of the locking piece 33 is a fixed end and the tip end portion is a free end, and the locking piece 33 can bend in the height direction with the base end portion as a fulcrum.

10 to 13 show a mounted state in which the adapter main body 110 is inserted into the holder 1. Further, FIG. 14 shows a state in which the adapter main body 110 is being attached to the holder 1 or a state in which the adapter main body 110 is being taken out from the holder 1. The adapter body 110 is inserted into the holder 1 along the vertical direction. The adapter body 110 can be inserted into the holder 1 from both of the two insertion ports 2. FIG. 14 shows, as an example, a case where the adapter main body 110 is inserted into the holder 1 from the first side surface 113 side.

When the adapter body 110 is inserted through the insertion slot 2, the locking claw 34 is pushed by, for example, the first side surface 113 or the chamfered portion 118 of the adapter body 110. As a result, the locking piece 33 elastically deforms outward in the height direction as shown in FIG. When the upper surface 111 of the adapter body 110 passes through the locking claw 34, the locking piece 33 automatically returns to its original straight state due to its elastic restoring force as shown in FIGS. 10 to 13. When the adapter body 110 is inserted into the holder 1, the first side surface 113 of the adapter body 110 is locked by the locking claws 34 of the pair of locking pieces 33, and the second side surface 114 of the adapter body 110 is also a pair of locking pieces. It is locked by the locking claw 34 of 33. The locking claw 34 of the locking piece 33 abuts or faces the first side surface 113 and the second side surface 114 of the adapter main body 110 via a gap. At that time, it is preferable that the inclined surface 35 of the locking claw 34 of the locking piece 33 faces the chamfered portion 118 of the adapter main body 110 via a contact or a gap. The tip of the locking claw 34 of the locking piece 33 may come into contact with the chamfered portion 118 of the adapter body 110. In any case, since the adapter body 110 is locked to the locking claw 34 of the locking piece 33, the adapter body 110 cannot be pulled out from the insertion port 2. The adapter body 110 attached to the holder 1 is locked to the locking claw 34 of the locking piece 33 and stays in the holder 1 unless a separate pushing operation or pulling operation is performed as described later. For example, when the adapter main body 110 is attached to the holder 1 with the vertical direction of the holder 1 as the vertical direction, the adapter main body 110 is locked by the locking claw 34 on the insertion port 2 side located on the lower side. Therefore, it is surely prevented that the adapter main body 110 falls by its own weight from the insertion port 2 located on the lower side. In the mounted state, the upper surface 111 of the adapter main body 110 is preferably located on the upper plate portion 11 side, and the lower surface 112 is located on the base plate portion 10 side, but it may be upside down.

In this way, the adapter body 110 is held between the locking claws 34 of the pair of locking pieces 33 extending to one side in the vertical direction and the locking claws 34 of the pair of locking pieces 33 extending to the other side in the vertical direction. The vertical position is regulated. Further, the lateral position of the adapter main body 110 is regulated by the pair of side plate portions 12, and the height position of the adapter main body 110 is regulated by the upper plate portion 11 and the base plate portion 10. Therefore, the adapter body 110 is firmly held by the holder 1. In the plan view of the mounted state as shown in FIG. 11, most of the screw holes 20 of the base plate portion 10 are hidden by the adapter main body 110 and cannot be seen.

When removing the adapter body 110 from the holder 1, the adapter body 110 is pulled or pushed toward one side or the other side in the vertical direction, and the adapter body 110 is pulled out from one insertion port 2 or the other insertion port 2. Extrude. When the locking claw 34 of the locking piece 33 is pushed by the first side surface 113 or the second side surface 114 of the adapter body 110 when the adapter main body 110 is pulled out from the insertion port 2, the locking piece 33 is high as shown in FIG. It elastically deforms outward in the longitudinal direction to allow the adapter body 110 to pass through. When the adapter body 110 is pulled out from the holder 1, the locking piece 33 automatically returns to its original state. In this way, the adapter main body 110 can be inserted into the holder 1 from two vertical directions, and the adapter main body 110 can be pulled out from the holder 1 in two vertical directions.

In the operation of attaching and detaching the adapter main body 110, the first power cord 120 and the second power cord 130 of the adapter main body 110 can be passed through the vertical slit 30. Therefore, it is not necessary to insert or pull out the first power cord 120 or the second power cord 130 from the insertion port 2 over the entire length thereof. Therefore, the adapter body 110 can be easily attached to the holder 1 even when the first power cord 120 or the second power cord 130 is connected to the adapter body 110, and the adapter body 110 can be attached from the holder 1 to the holder 1. It can be easily removed.

Further, since the base plate portion 10 can be screwed to, for example, a wall or the like, the locking piece 33 is located away from the wall or the like. Therefore, the adapter body 110 can be easily attached to and detached from the holder 1 while the holder 1 is attached to the wall or the like. The holder 1 may be attached by a method other than screwing. For example, the holder 1 may be adhesively fixed to a wall or the like with double-sided tape.

Further, since the locking piece 33 is provided next to the vertical slit 30, the locking piece 33 can be easily formed, and the structure of the upper plate portion 11 can be simplified. Since the locking pieces 33 are provided on both sides of the vertical slit 30, the adapter main body 110 can be firmly locked by the pair of locking pieces 33 located on both sides of the vertical slit 30. Further, since the adapter body 110 can be firmly locked by the pair of locking pieces 33 without making the locking piece 33 excessively wide, the locking piece 33 can be elastically deformed smoothly, and the adapter body 110 can be attached and detached. Becomes easier.

15 and 16 show examples of use in which the holder 1 is attached to another member such as a wall. In this usage example, the holder 1 is attached to the vertical frame 202 of the door frame 201. The vertical direction of the holder 1 is the vertical direction. Therefore, the adapter main body 110 can be inserted into the holder 1 from two directions, up and down. Even when the vertical direction of the holder 1 is set to the vertical direction in this way, the adapter main body 110 attached to the holder 1 is locked by the locking claw 34 without falling from the lower insertion port 2. The attached state is maintained. A door opening / closing device 204 for electrically opening / closing the door 203 is attached to the door 203, and the DC power converted by the adapter 100 is supplied to the door opening / closing device 204 via the relay box 205. The door.

In the present embodiment, a pair of locking pieces 33 are provided in the vicinity of one insertion port 2, but only one locking piece 33 may be provided for one insertion port 2. , Three or more may be provided. Further, the number and arrangement of the locking pieces 33 may not be symmetrical in the vertical direction, and may be an asymmetrical number and arrangement. The locking piece 33 is provided on the upper plate portion 11, but for example, the locking piece 33 may be provided on the side plate portion 12. Further, although the locking piece 33 extends in the vertical direction, the locking piece 33 may extend in the horizontal direction or the height direction, for example.

The vertical slit 30 and the horizontal slit 31 may be omitted. The through hole 21 of the base plate portion 10 may be omitted. The holder 1 may be made of metal other than resin.
