Description
본 고안은 충전기에 관한 것으로, 특히 휴대폰에 핸즈프리잭으로 연결되어 휴대폰을 충전시키는 휴대폰 충전기에 관한 것이다.The present invention relates to a charger, and more particularly, to a mobile phone charger connected to the mobile phone by a hands free jack to charge the mobile phone.
일반적으로, 휴대폰 충전기는 휴대폰의 인터페이스 커넥터로 휴대폰에 연결되어 휴대폰에 전원을 공급하는 기기로, 콘센트에 탈착가능하게 끼워져 전원을 공급받아 휴대폰의 전압에 맞는 전압으로 변환한 후 휴대폰에 전원을 인가하여 휴대폰을 충전하게 되는 것이다.In general, a mobile phone charger is a device that supplies power to a mobile phone by connecting it to the mobile phone through an interface connector of the mobile phone. The mobile phone charger is detachably inserted into an outlet, receives power, converts the voltage to a voltage of the mobile phone, and then applies power to the mobile phone. It will charge your phone.
종래의 휴대폰 충전기는 가정용 전압을 휴대폰용 저전압으로 바꾸는 트랜스기판(116)이 내장된 케이스(110)와, 상기 케이스(110)에 회전가능하게 삽입설치되고 전기콘센트에 끼워져 상기 트랜스기판(116)에 전원을 인가하는 회전플러그(120)로 이루어진 구조이다.The conventional mobile phone charger has a case 110 with a built-in transformer substrate 116 for converting a home voltage into a low voltage for a mobile phone, and is rotatably inserted into the case 110 and fitted into an electrical outlet to the trans substrate 116. It is a structure consisting of a rotary plug 120 for applying power.
즉, 종래의 휴대폰 충전기의 회전플러그(120)는 케이스(110)에 회전가능하게 끼워져 전기콘센트에 꽂아 사용할 때에는 펼쳐 사용하게 되고, 충전하지 않을 때에는 접히도록 된 것이다.That is, the rotary plug 120 of the conventional mobile phone charger is rotatably fitted to the case 110 to be used when it is plugged into an electrical outlet for use, and folded when not being charged.
종래의 휴대폰 충전기는 그 회전플러그(120)가 케이스(110)에 회전가능하게 설치되어 있으나, 일측 지점에서 고정되지 않아 회전플러그(120)가 쉽게 회전하게 되어 휴대시에도 불편할 뿐만 아니라, 잦은 회전에 의해 회전플러그(120)와 트랜스기판(116)과의 접촉부가 고장나기 쉬운 문제점이 있었다.In the conventional mobile phone charger, the rotary plug 120 is rotatably installed in the case 110, but is not fixed at one side, so that the rotary plug 120 is easily rotated, which is inconvenient in carrying, and frequently rotates. As a result, the contact portion between the rotary plug 120 and the trans substrate 116 tends to be broken.
또한, 케이스(110)와 회전플러그(120) 사이의 간격을 없애거나 좁게 하여 접촉에 의해 회전플러그(120)를 고정시키기도 하지만, 회전플러그(120)의 회전이 원활하지 않아 조작하는데 힘이 많이 드는 문제점이 있었다.In addition, although the gap between the case 110 and the rotary plug 120 is eliminated or narrowed, the rotary plug 120 may be fixed by contact, but the rotation of the rotary plug 120 may not be smooth, and thus a lot of effort is required to operate the rotary plug 120. There was a problem.
이에 본 고안은 상기한 바의 제반 문제점들을 해소하기 위해 안출된 것으로, 회전플러그를 원활하게 회전시킬 수 있고 그 회전플러그를 접었을 때와 폈을 때 간편하게 고정할 수 있을 뿐만 아니라 회전플러그를 부드럽게 회전시킬 수 있도록 된 접이식 휴대폰 충전기를 제공함에 그 목적이 있다.The present invention has been devised to solve the above problems, it is possible to smoothly rotate the rotary plug and can be easily fixed when the rotary plug is folded and fold, as well as to smoothly rotate the rotary plug. The purpose is to provide a folding mobile phone charger.
상기한 바의 목적을 달성하기 위한 본 고안은, 플러그 수용홀이 형성된 충전기 케이스가 구비되고, 상기 플러그 수용홀의 측벽에 한쌍의 회전홀이 서로 마주보게 각각 형성되며, 일측에 한쌍의 회전편이 각각 돌출형성된 회전플러그가 상기 회전홀에 그 회전편으로 회전가능하게 끼워지고, 상기 회전편의 외주면에 고정돌기가 원주방향을 따라 소정간격을 두고 돌출형성되며, 상기 각 회전홀의 내측벽에 사각링 형상의 고정구가 탈착가능하게 각각 설치되며, 상기 고정구는 일측이 요철부와 요홈부가 반복해서 형성되도록 주름지게 형성된 구조이다.The present invention for achieving the object of the bar is provided with a charger case formed with a plug receiving hole, a pair of rotating holes are formed to face each other on the side wall of the plug receiving hole, respectively, a pair of rotating pieces protrude on one side, respectively The rotating plug is rotatably fitted into the rotating hole by the rotating piece, and fixing protrusions are formed on the outer circumferential surface of the rotating piece at predetermined intervals along the circumferential direction, and a square ring-shaped fastener is formed on the inner wall of each rotating hole. Are each detachably installed, the fastener has a structure that one side is wrinkled so that the irregularities and grooves are formed repeatedly.
따라서, 상기 고정구는 복수개의 안착홈이 형성되고 탄성적으로 확개가능하여 회전편의 고정돌기를 물어 잡아 회전플러그를 고정지지하고 부드럽게 회전시킬 수 있게 되는 것이다.Therefore, the fastener is a plurality of seating grooves are formed to be elastically expandable to catch the fixing projections of the rotating piece to be able to securely support the rotation plug and rotate smoothly.
