Description

[Technical field] The present invention relates to an electric device such as an adapter.

(Conventional technology and its disadvantages)

Generally, an adapter is widely used to supply current from a household power supply to a word processor, a calculator, or the like. The conventional adapter includes a substantially rectangular adapter body 2 as shown in FIG. A pair of AC pins 4 is provided on one surface of the adapter body 2.
Is plugged into a household power outlet. A code wire 6 is connected to the other surface of the adapter body 2.
A bush member 8 is interposed between one end of the adapter body 2 and the adapter body 2, and the bush member 8 protects the cord 6.
An electric terminal 10 is provided at the other end of the code line 6, and the electric terminal 10 is electrically connected to an electric device such as a word processor.

However, in the conventional adapter, as easily understood from FIG. 5, there is a problem that the accommodation of the code wire 6 is not easy. That is, when stored, the cord wire 6
Is wound around the adapter body 2, but in such a wound state, the bush member 8 protrudes from the adapter body 2, and this bush member 8 tends to be an obstacle during storage. Further, the lead wire 6 wound around the adapter body 2 is easily shifted laterally and comes off, and it is difficult to hold the cord wire 6 wound.

[Purpose of the invention]

The present invention has been made in view of the above-described circumstances, and a main object of the present invention is to provide an adapter that can be easily stored when not in use and that can also prevent breakage of a cord wire.

Another object of the present invention is to provide an adapter that can accommodate the cord wire 6 and prevent the cord wire 6 from coming off.

[Outline of the invention]

According to the present invention, an adapter body having a bottom surface, a top surface, and four side walls, a cord wire extending from the adapter body, a bush member provided at one end of the cord wire, and an electric wire provided at the other end of the cord wire And a terminal portion, the specific side wall among the four side walls is provided with a groove-shaped first concave portion having a depth larger than the outer dimension of the bush member, and the bush member defines the first concave portion. The first on the prescribed surface
Is provided along the bottom surface that defines the first concave portion without protruding outward from the concave portion, and has a groove-shaped second surface extending over substantially the entire periphery through the first concave portion on the four side walls. A concave portion is provided, and a clamp means is provided on a surface defining the first concave portion so as not to protrude outward. When the code line is stored, the code line is inserted into the second concave portion. The electrical terminal is detachably mounted on the clamp means and accommodated in the first recess.

[Specific examples of the invention]

Hereinafter, a specific example of the adapter of the present invention will be described with reference to FIGS.

1 to 3, the illustrated adapter includes an adapter body 22. The adapter body 22 has a rectangular bottom surface 24 and a top surface 26, and four side surfaces 28, 30, 32 and 34 existing between the bottom surface 24 and the top surface 26. On the right side of the bottom surface 24 in FIG.
37 (FIG. 3) are provided. The AC pins 36 and 37 are inserted into a household power outlet (not shown), so that the household power supply is connected to the pair of AC pins 36 and 37.
Is supplied to the adapter main body 22 via the.

In the specific example of the adapter, a substantially rectangular concave portion 38 (constituting a first concave portion) is provided at a predetermined portion of the side surface 32 as one surface.
Is provided. The recess 38 is provided substantially at the center of the side surface in the width direction, extends from the right portion in FIG. 2 to the side surface 34, and has a depth greater than the outer diameter of a bush member described later. A code line 40 extends from a wall surface 38a defining the recess 38. A flexible bush member 42 is interposed between one end of the cord 40, that is, between the cord 40 and the wall defining the surface 38a. The bush member 42 extends rightward in FIGS. 1 and 2 within the recess 38 and does not protrude from the recess 38. This bush member
Reference numeral 42 is for preventing breakage of the cord 40, and may be provided integrally with the cord 40, or may be detachably attached to the cord 40. Code wire 40
An electric terminal 44 is provided at the other end of the electric terminal.
44 is electrically connected to a terminal of an electric device such as a word processor, so that a current from a household power supply is supplied to the electric device via an adapter as required.

In the example adapter, the four side walls 28, 30, 32 and 34
Further, there is provided a cord storage recess 50 (constituting a second recess) extending substantially all around the recess 38. The cord storage recess 50 is provided somewhat closer to the upper surface 26 than the center of the four side surfaces 28, 30, 32, and 34, and its depth is set to be larger than the outer diameter of the cord wire 40. Code wire 40
When storing the adapter body, as shown in FIG.
The cord wire 40 extending from the cord 22 is wound around the cord storage recess 50 of the adapter body 22 as required. By this winding, the code wire 40 is stored in the storage recess 50, and the code wire 40 does not protrude outward from the four side surfaces 28, 30, 32 and 34 in the stored state. Further, in the housed state, the lateral displacement of the wound cord wire 40 at the portion defining the side surface of the accommodation recess 50 is reliably prevented, and the detachment of the cord wire 40 is also prevented. In the illustrated example, the depth of the recess 38 is deeper than the cord storage recess 50, and the width thereof is also wider than the storage recess 50.In this regard, in the side surface 34,
One side (the right side in FIG. 3) defining the storage recess 50 is linearly inclined inward from the side surface 32 toward the side surface 28, and the width of the storage recess 50 is gradually reduced.

The adapter of the specific example is further provided with a clamp means 52 in order to more reliably prevent the cord wire 40 from coming off during storage. The illustrated clamping means 52 is composed of a pair of clamping members 54 and 56 which are arranged at an interval in the vertical direction in FIG. 3 (the direction perpendicular to the paper in FIGS. 2 and 4). Members 54 and 56 are recessed
It protrudes to the right in FIG. 3 from a surface 38b that defines the side surface of 38. The clamp member 54 is thicker than the other clamp member 56. Therefore, as shown in FIG. 4, the electric terminal portion 44 of the cord 40 (specifically, the terminal 44a exposed to the outside) is connected to the pair of clamp members 54. When the clamp member 56 is inserted between the clamp members 54 and 56, mainly the thin clamp member 56 is elastically deformed, and the electric terminal 44 is held between the clamp members 54 and 56 by the elastic force of the clamp member 56. Further, a projection 54a for holding is integrally provided at a tip portion of the clamp member 54 in order to prevent the electric terminal portion 44 from coming off extremely easily.

As described above, one specific example of the adapter according to the present invention has been described. However, the present invention is not limited to the specific example, and various modifications or modifications can be made without departing from the scope of the present invention.

For example, the AC pins 36 and 37 protruding from the bottom surface 24 may be configured to be housed in the adapter body 22. In this configuration, if the AC pins 36 and 37 are also accommodated, there is substantially no one protruding outward from the adapter main body 22, and the storage of the adapter is further facilitated.

[Effect of the invention]

According to the present invention, since the bush member of the cord is provided on the surface defining the first recess, the bush member is housed in the first recess and does not protrude outward from the adapter body. . In this connection, the cord wire extends straight from the surface of the first recess, so that a large bending force does not act on the bush member, and the breakage of the bush member is effectively prevented. Can be prevented.

In addition, since the second concave portion is provided in the four walls of the adapter main body, the cord wire can be accommodated in the second concave portion by winding the cord wire around the second concave portion, and the cord wire can be removed from the adapter main body. It does not protrude outward.

Further, since the first concave portion is provided with the clamping means, the terminal part can be detachably mounted on the adapter body by holding the electric terminal part of the cord wire on the clamping means, and the adapter body of the cord wire can be detached. Can be reliably prevented from coming off.
