첨부된 예시도면 도 1은 종래의 휴대 무선전화기용 전원공급장치를 나타낸 것으로, 먼저 충전장치(10)의 하부에는 프론트 커버(12)가 설치되어 있는데, 이 프론트 커버(12)의 내부에는 회로패턴을 형성한 인쇄회로기판(14)이 안착되어 있고, 이 인쇄회로기판(14)의 일측선단 부위에는 이 인쇄회로기판(14)과 연결되도록 컨텍터핀(16)을 구비한 컨넥터(18)가 장착되어 있으며, 이 커넥터(18)의 양편에는 일정의 곡률로 구부러진 제 1,2충전단자(20,22)가 컨넥터(18)와 용접.연결되어 있다.1 is a view illustrating a conventional power supply device for a portable radiotelephone. First, a front cover 12 is installed at a lower portion of a charging device 10, and a circuit pattern is formed inside the front cover 12. A printed circuit board 14 having a recessed shape is mounted, and a connector 18 having a contact pin 16 is connected to one end portion of the printed circuit board 14 so as to be connected to the printed circuit board 14. The first and second charging terminals 20 and 22 which are bent at a predetermined curvature are welded and connected to the connector 18 on both sides of the connector 18.

그리고, 상기 제 1,2충전단자(20,22)에는 이 제 1,2충전단자(20,22)가 관통.돌출되도록 이와 대응하는 부위에 관통공(24)을 구비한 리어 커버(26)가 결합되어 있어서, 사용자가 휴대 무선전화기에 전원을 공급하고자 접지면(28)을 구비한 밧데리팩(30)을 충전시키고자 할 경우에는, 상기 제 1,2충전단자(20,22)에 밧데리팩(30)의 접지면(28)을 안착.접촉시켜 전원을 충전공급시키게 되는 것이다.The first and second charging terminals 20 and 22 have a rear cover 26 having a through hole 24 in a portion corresponding to the first and second charging terminals 20 and 22 so as to penetrate and protrude. Is coupled, when the user wants to charge the battery pack 30 having a ground plane 28 to supply power to the portable radiotelephone, the battery to the first and second charging terminals (20, 22) The ground plane 28 of the pack 30 is seated and contacted to supply power.

또한, 사용자의 편의에 따라 충전장치를 차량 내에 설치시에는, 상기 컨넥터(18)에 전원공급 케이블을 삽입.연결시키고, 이 케이블의 타단에 구비된 잭을 차량내에 구비된 잭에 연결시켜 전원을 공급시키면 되는 것이다.In addition, when the charging device is installed in the vehicle according to the user's convenience, a power supply cable is inserted and connected to the connector 18, and the jack provided at the other end of the cable is connected to the jack provided in the vehicle to supply power. All you have to do is supply it.

그러나, 상기와 같은 종래의 휴대 무선전화기용 전원 충전장치는 먼저, 충전단자(20,22)는 상향의 곡면으로 구부러진 상태에서 리어 커버(26)의 관통공(24)을 통하여 외부로 인출되어 있어서, 예컨데 사용자의 취급부주위로 인한 충전단자(20,22)의 충격 혹은 밧데리팩(30)의 잦은 충전 접촉시, 이 충전단자(20,22)의 구부러진 부위가 형상이 변형되어, 밧데리팩(30)과의 불안정한 접촉으로 정확한 충전이 이루어지지 않으며, 아울러 상기 리어 커버(26)의 관통공(24)을 통하여 외부 먼지 혹은 이물질이 유입되어 충전단자(20,22)의 텐션력 저하로 인한 밧데리팩(30)과의 접촉불량을 유발시키게 되는 문제점이 있다.However, the above-described conventional power charging device for a portable radiotelephone is first drawn out to the outside through the through hole 24 of the rear cover 26 in a state where the charging terminals 20 and 22 are bent upward. For example, when the charging terminals 20 and 22 are impacted by the handling of the user's handling or frequent charging contacts of the battery pack 30, the bent portion of the charging terminals 20 and 22 is deformed, and thus the battery pack 30 ), The battery pack may not be accurately charged due to unstable contact with the battery pack, and external dust or foreign matter may enter through the through hole 24 of the rear cover 26, resulting in a decrease in tension force of the charging terminals 20 and 22. There is a problem that causes poor contact with the (30).

또한, 상기 충전단자(20,22)가 인쇄회기판(14)에 구비된 컨넥터(18)와 땜납에 의해 연결.고정됨으로 해서, 이 충전단자(20,22)의 교체 수리시, 용이한 분해 및 재 조립이 구조상 어려워 사용자에게 제품의 신뢰도를 저하시키게 되는 문제점이 있었다.In addition, since the charging terminals 20 and 22 are connected and fixed to the connector 18 provided on the printed circuit board 14 by soldering, it is easy to disassemble the charging terminals 20 and 22 during the replacement and repair of the charging terminals 20 and 22.

Since the same reference numerals as those of FIG. 1 denote the same parts, a description thereof will be omitted and different from FIG. 1. Only points will be described.

첨부된 예시도면 도 2를 참조하면, 먼저 프론트 커버(12)에 결합된 고정부재(40)의 상면에는 인쇄회로기판(14)이 안착.고정되어 있고, 이 프론트 커버(12)의 상면에 대응 결합되는 리어 커버(42)의 일정 저면에는 이와 일체를 이루며 일정길이로 하향 돌출된 한쌍의 리브(44)가 상호 이격된 상태로 형성되어 있으며, 이 리브(44)의 내부에는 양편에 제 1,2충전단자(46,48)를 구비하는 충전부재(50)가 삽입.결합되어 있다.2, the printed circuit board 14 is seated and fixed on an upper surface of the fixing member 40 coupled to the front cover 12, and corresponds to an upper surface of the front cover 12. A predetermined bottom of the rear cover 42 to be coupled is formed in a state in which a pair of ribs 44 protruding downward with a predetermined length are integrally spaced apart from each other. A charging member 50 having two charging terminals 46 and 48 is inserted and coupled.

여기서, 상기 충전부재(50)의 내부에는 걸림턱(52)을 구비한 제 1,2충전단자(46,48)가 양편으로 인출된 상태로 설치되어 있고, 이 제 1,2충전단자(46,48)의 사이에는 탄성스프링(54)이 탄지되어 있으며, 이 제 1충전단자(46)는 탄성스프링(54)의 탄발력으로 인쇄회로기판(14)의 회로패턴상에 형성된 접점(56)에 압압.접촉되어 있다.Here, the first and second charging terminals 46 and 48 having the locking jaw 52 are installed in both sides of the charging member 50, and the first and second charging terminals 46 are installed on both sides thereof. The elastic spring 54 is held between the and 48, and the first charging terminal 46 is formed on the circuit pattern of the printed circuit board 14 by the elastic force of the elastic spring 54. Pressed in contact with.

또한, 상기 충전부재(50)의 중앙 외주면에는 고정돌기(58)가 돌출.형성되어 있고, 이 고정돌기(58)는 이와 대응하는 리브(44)의 내면에 압지되도록 구성되어 있다.In addition, a fixing protrusion 58 protrudes and is formed on the center outer circumferential surface of the filling member 50, and the fixing protrusion 58 is configured to be pressed on the inner surface of the corresponding rib 44.

상기와 같이 구성된 본 발명은 사용자가 휴대 무선전화기에 전원을 공급하는 밧테리팩(30)을 충전시키고자 할 경우, 첨부된 예시도면 도 2에 도시된 바와 같이 먼저 리어 커버(42)의 상면으로 인출된 제 2충전단자(48)에 이와 대응하는 밧데리팩(30)의 접지면(28)을 접촉.안착시켜 전원을 충전하게 되는데, 이때 상기 밧데리팩(30)이 제 2충전단자(48)를 자체 하중으로 압압.밀착시, 이 제 2충전단자(48)는 하강하면서 저면에 탄지된 탄성스프링(54)을 압축하게 되고, 이에 따라 탄성스프링(54)의 압축에 의해 상대적으로 탄발력이 강하게 작용하여, 결국 제 1,2충전단자(46,48)가 인쇄회로기판(14)의 접점(56)과 밧데리팩(30)의 접지면(28)에 더욱 압압.접촉되어 충전을 안정하게 할 수 있는 것이다.According to the present invention configured as described above, when the user wants to charge the battery pack 30 supplying power to the portable radiotelephone, the drawing is first drawn out to the upper surface of the rear cover 42 as shown in FIG. The second charging terminal 48 contacts the ground plane 28 of the battery pack 30 corresponding thereto. The battery pack 30 charges the power by seating the second charging terminal 48. When pressing and adhering to its own load, the second charging terminal 48 compresses the elastic spring 54 supported on the bottom while descending, thereby providing a relatively elastic force by the compression of the elastic spring 54. As a result, the first and second charging terminals 46 and 48 are further pressed and contacted with the contacts 56 of the printed circuit board 14 and the ground surface 28 of the battery pack 30 to stabilize charging. It can be.

또한, 상기 충전부재(50)는 리어 커버(42)의 리브(44) 내면에 밀착된 상태로 억지결합되어 있어, 이와 같은 구조상 리브(44)의 내부를 통하여 먼지 혹은 이물질이 유입되는 것을 방지함으로써, 제 1충전단자(46)의 불안정한 접촉을 방지하게 되고, 아울러 충전부재(50) 내에 구비된 제 1,2충전단자(46,48)가 인쇄회로기판(14)상에 직접적으로 접촉되어 있어, 별도의 부품과 땜납의 조립공정이 제거되어 작업성을 향상시키게 되는 것이다.In addition, the filling member 50 is forcibly coupled in close contact with the inner surface of the rib 44 of the rear cover 42, thereby preventing the inflow of dust or foreign matter through the interior of the rib 44 in this structure In order to prevent unstable contact of the first charging terminal 46, the first and second charging terminals 46 and 48 provided in the charging member 50 are in direct contact with the printed circuit board 14. In addition, the process of assembling separate parts and solder is eliminated to improve workability.

또한, 상기 제 1,2충전단자(46,48)는 충전부재(50) 내에 인출.삽입이 용이하도록 탄성스프링(54)이 설치되어 있어서, 외부의 충격 혹은 밧데리팩(30)의 잦은 충전 접촉시에도 제 1,2충전단자(46,48)의 변형을 방지하여 전원의 충전공급을 정확하게 할 수 있는 것이다.In addition, the first and second charging terminals 46 and 48 are provided with an elastic spring 54 to facilitate withdrawal and insertion into the charging member 50, so that external shocks or frequent charging contacts of the battery pack 30 are caused. In this case, the first and second charging terminals 46 and 48 may be prevented from being deformed to accurately charge and supply power.

위와 같이 본 발명은 외부 충격에 의한 충전단자의 변형을 방지하여 이와 접촉되는 밧데리팩에 전원을 정확하게 충전시킬 수 있고, 아울러 충전부재가 리브에 억지 삽입되어 있어서, 외부로 부터의 먼지 혹은 이물질의 유입을 방지할 수 있으며, 아울러 충전단자의 수리시, 분해 또는 조립을 용이하게 할 수 있는 효과가 있다.As described above, the present invention prevents the deformation of the charging terminal due to external shock, thereby accurately charging the battery pack in contact with the battery pack. Also, since the charging member is inserted into the rib, the inflow of dust or foreign matter from the outside is prevented. It can be prevented, and also in the repair of the charging terminal, there is an effect that can facilitate the disassembly or assembly.
