できる。In the following, the operation of the plug removal preventing structure of the cross-type ear-hearing hearing aid to which the present invention is applied will be described. After inserting the plug 4 into the receptacle of the hearing aid main body 1, as shown in FIG. 3A, the belt 6 is wound around the hearing aid main body 1, and the spherical portion 6 a is inserted into the hole 6 b of the belt 6. Then, the belt 6 can be stably wound around the hearing aid body 1. Furthermore, since the concave portion 1a is provided in the hearing aid main body 1 and the convex portion 6c of the belt 6 is engaged with the concave portion 1a,
The belt 6 can be more reliably wound around the hearing aid body 1.
【００１７】従って、プラグ４は、プラグ４の外皮４ａ

てもプラグ４がレセプタクルから外れることはない。Accordingly, the plug 4 is formed by the outer cover 4a of the plug 4.
The plug 4 is firmly connected to the receptacle by the belt 6 integrally formed with the plug 4, and the plug 4 does not come off from the receptacle even if some force acts in the direction in which the plug 4 comes off.

外力による接続部Ｃへの負荷は、軽減される。Further, as shown in FIG. 4, a belt 6 integrally formed with the outer skin 4a of the plug 4 winds the hearing aid body 1 at a portion adjacent to the plug 4, thereby connecting the plug 4 to the receptacle. In the vicinity of C, a contact portion 6e that is in close contact with the back surface 1b of the hearing aid main body 1 is formed on the belt 6. The contact portion 6e reduces the load on the connection portion C due to the external force in the direction of the arrow A or the external force in the direction of the arrow B applied to the cord 2 when the hearing aid main body 1 is worn on the pinna.

ことなく接続部Ｃは安定に保たれる。That is, the external force in the direction of arrow A or the external force in the direction of arrow B acts in the direction in which the back surface 1b is in close contact with the contact portion 6e or in the direction away therefrom.
, The contact between the back surface 1b and the contact portion 6e is maintained, and the connection portion C is stably maintained without the plug 4 separating from the receptacle.

抜ける方向にコード２を引っ張ることが多いが、多少乱
暴に扱ったとしても、プラグ４と補聴器本体１との電気
的接触は安定に保たれ、補聴器としての機能を低下させ
ることはない。In particular, a hearing aid wearer of an infant often pulls the cord 2 in a direction in which the plug 4 is pulled out. However, even if the cord 4 is handled somewhat abruptly, the electrical contact between the plug 4 and the hearing aid main body 1 is kept stable. It does not degrade the function as a hearing aid.

る。On the other hand, when the plug 4 is to be removed from the receptacle of the hearing aid main body 1, the protrusion 6d of the belt 6 is pressed with a nail or the like, and as shown in FIG. The belt 6 is easily released from the belt 6b to be in an open state.
Then, the plug 4 can be removed from the receptacle.

別体であっても構わない。In the above-described embodiment of the present invention, the case where the belt 6 and the outer cover 4a of the plug 4 are integrated has been described. However, if the belt 6 presses the upper part of the plug 4 against the hearing aid body 1, The plug 4 and the belt 6 may be separate bodies.

However, the present invention is not limited to this, and can be applied to other sound-listening devices as long as the device has a shape adapted to the upper part of the pinna and includes a receptacle and a plug connected to the receptacle. Needless to say.
