플러그 커넥터 및 그 제조방법Plug connector and its manufacturing method
본 발명은 플러그 커넥터에 관한 것이다. 보다 상세하게는 휴대용 전자기기 내의 인쇄회로기판에 실장된 리셉터클 커넥터에 대응하여 체결되는 플러그 커넥터에 관한 것이다. The present invention relates to a plug connector. More particularly, the present invention relates to a plug connector fastened corresponding to a receptacle connector mounted on a printed circuit board in a portable electronic device.

In this case, the fastening between the plug contact and the receptacle contact may be poor, and electrical contact may not be properly performed.

전술한, 그리고 추가적인 양상들은 첨부된 도면들을 참조하여 설명되는 실시 예들을 통해 명백해질 것이다. 본 명세서에서 각 도면의 대응되는 구성 요소들은 동일한 번호로 참조된다. 또한, 관련된 공지 기술에 대한 설명이 본 발명의 요지를 불필요하게 흐릴 수 있다고 생각되는 경우 그에 대한 설명은 생략될 수 있다.The foregoing and further aspects will become apparent from the embodiments described with reference to the accompanying drawings. Corresponding elements in each figure are referred to by the same numerals in this specification. In addition, descriptions of related well-known techniques may be omitted if it is deemed that they may unnecessarily obscure the subject matter of the present invention.
이하, 첨부된 도면들을 참조하여 본 발명을 상세히 설명하기로 한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 3은 본 발명의 일 실시예에 따른 플러그 커넥터의 사시도이고, 도 4는 도 3에 도시된 플러그 커넥터의 분해 사시도이며, 도 5는 도 3에 도시된 플러그 커넥터의 평면도이다.3 is a perspective view of a plug connector according to an embodiment of the present invention, FIG. 4 is an exploded perspective view of the plug connector shown in FIG. 3, and FIG. 5 is a plan view of the plug connector shown in FIG. 3.
도 3 내지 도 5를 참조하여 설명하면, 본 발명의 일 양상에 따른 플러그 커넥터(100)는 플러그 컨택트(30)와, 플러그 컨택트(30)를 잡아주는 플러그 인슐레이터(10)와, 플러그 인슐레이터(10)를 감싸는 플러그 쉘(20)을 포함한다.3 to 5, a plug connector 100 according to an aspect of the present invention includes a plug contact 30, a plug insulator 10 holding the plug contact 30, and a plug insulator 10. It includes a plug shell 20 surrounding ().
여기서, 플러그 인슐레이터(10)와 플러그 쉘(20)은 세라믹 재질을 이용하여 일체로 형성된다. 플러그 인슐레이터(10)와 플러그 쉘(20)이 세라믹 재질을 이용하여 일체로 형성되므로, 플러그 커넥터(100)의 내구성이 향상된다. 또한, 세라믹은 자기 윤활성을 가지므로 플러그 커넥터(100)를 휴대용 전자기기의 리셉터클 커넥터에 장탈착하는 과정에서 플러그 쉘(20)과 휴대용 전자기기가 마찰되어 손상되는 것이 방지된다. 그리고 장탈착 시에 마찰력이 감소되므로 삽입 작업이 용이해진다. 플러그 인슐레이터(10)와 플러그 쉘(20)을 일체로 형성하므로, 제조과정도 간소화된다. 뿐만 아니라 종래의 플러그 커넥터(100)를 리셉터클 커넥터에 장착하면 플러그 커넥터(100)의 금속 플러그 쉘(20)에 의해 휴대용 전자기기의 수신 감도가 저하될 수 있다. 그러나 본 발명에 따른 플러그 커넥터(100)는 플러그 쉘(20)이 세라믹 재질로 이루어져 있으므로 휴대용 전자기기의 수신 감도에 영향을 미치지 않아 수신감도가 상대적으로 향상되는 효과가 있다.Here, the plug insulator 10 and the plug shell 20 are integrally formed using a ceramic material. Since the plug insulator 10 and the plug shell 20 are integrally formed using a ceramic material, durability of the plug connector 100 is improved. In addition, since the ceramic has self-lubricating property, the plug shell 20 and the portable electronic device are prevented from being damaged by friction in the process of mounting and detaching the plug connector 100 to the receptacle connector of the portable electronic device. And since the frictional force is reduced at the time of desorption, insertion work becomes easier. Since the plug insulator 10 and the plug shell 20 are integrally formed, the manufacturing process is also simplified. In addition, when the conventional plug connector 100 is mounted on the receptacle connector, the reception sensitivity of the portable electronic device may be reduced by the metal plug shell 20 of the plug connector 100. However, since the plug shell 20 is made of a ceramic material, the plug connector 100 according to the present invention does not affect the reception sensitivity of the portable electronic device, and thus the reception sensitivity is relatively improved.
본 발명의 다른 양상에 따르면, 플러그 인슐레이터(10)와 플러그 쉘(20)은 분말 사출 성형에 의해 일체로 형성될 수 있다. 플러그 인슐레이터(10)와 플러그 쉘(20)이 분말 사출 성형에 의해 형성되므로 제조 과정이 간소화되고, 다양한 형상을 구현할 수 있게 된다.According to another aspect of the invention, plug insulator 10 and plug shell 20 may be integrally formed by powder injection molding. Since the plug insulator 10 and the plug shell 20 are formed by powder injection molding, the manufacturing process may be simplified and various shapes may be realized.
본 발명의 또 다른 양상에 따르면, 일체로 형성된 플러그 인슐레이터(10)와 플러그 쉘(20)의 선단 모서리 부분(20a)은 곡선으로 이루어진다. 종래 기술에 따른 플러그 커넥터(100)를 휴대용 전자기기의 리셉터클 커넥터에 삽입할 때 양자의 위치가 어긋나는 경우 플러그 커넥터(100)는 리셉터클 커넥터에 삽입되지 않는다. 이 때 계속 힘을 가하면 플러그 쉘 모서리 부분과 휴대용 전자기기가 손상될 수 있다. 그런데 본 발명에 따른 플러그 인슐레이터(10)와 플러그 쉘(20)의 선단 모서리 부분(20a)은 곡선으로 이루어지므로, 양자의 위치가 어긋나는 경우에도 양자간의 마찰에 의한 손상이 줄어들게 된다.According to another aspect of the invention, the integrally formed plug insulator 10 and the leading edge portion 20a of the plug shell 20 are curved. When the plug connector 100 according to the prior art is inserted into the receptacle connector of the portable electronic device, the plug connector 100 is not inserted into the receptacle connector when the positions thereof are shifted. Continued force at this point can damage the plug shell edge and portable electronics. However, since the tip edge portion 20a of the plug insulator 10 and the plug shell 20 according to the present invention has a curved shape, damage caused by friction between the two is reduced even when the positions of the plug insulator 10 are shifted.
본 발명의 또 다른 양상에 따르면, 플러그 컨택트(30)의 일측면에는 고정돌기(31)가 형성된다. 플러그 컨택트(30)의 일측면에 고정돌기(31)가 형성되므로 플러그 컨택트(30)가 플러그 인슐레이터(10)에 삽입된 후 좌우로 유동하지 않게 된다. 따라서, 커넥터 플러그와 리셉터클 커넥터간의 전기적 접촉이 양호하게 된다.According to another aspect of the invention, the fixing projection 31 is formed on one side of the plug contact (30). Since the fixing protrusion 31 is formed on one side of the plug contact 30, the plug contact 30 is not inserted into the plug insulator 10 and does not flow from side to side. Thus, the electrical contact between the connector plug and the receptacle connector is good.
도 6은 본 발명의 일 실시예에 따른 플러그 커넥터의 제조방법을 개략적으로 나타낸 흐름도이다.6 is a flowchart schematically illustrating a method of manufacturing a plug connector according to an exemplary embodiment of the present invention.
도 6을 참조하여 본 발명의 일 양상에 따른 플러그 커넥터의 제조방법을 설명하기로 한다.A method of manufacturing a plug connector according to an aspect of the present invention will be described with reference to FIG. 6.
먼저, 세라믹 분말에 안료를 첨가한다(S10). 세라믹 분말은 0.1 ~ 20㎛ 정도 크기가 사용될 수 있다. 안료로는 2종 이상의 금속산화물로 구성된 복합산화물계 안료가 사용될 수 있다.First, a pigment is added to the ceramic powder (S10). Ceramic powder may be used in the size of about 0.1 ~ 20㎛. As the pigment, a composite oxide pigment composed of two or more metal oxides may be used.
다음, 세라믹 분말과 유기 결합제를 혼합한다(S20). 유기 결합제는 고온에서 녹는 왁스 등이 될 수 있다. 유기 결합제는 융점이 약 180℃ 이하인 것이 좋다. 세라믹 분말과 유기 결합제의 비율은 대략 5:5 내지 7:3 정도가 바람직하다.Next, the ceramic powder and the organic binder are mixed (S20). The organic binder may be wax or the like which melts at high temperature. The organic binder preferably has a melting point of about 180 ° C. or less. The ratio of the ceramic powder and the organic binder is preferably about 5: 5 to 7: 3.
다음, 사출 성형기를 이용하여 플러그 쉘과 플러그 인슐레이터가 일체화된 생성형체를 형성한다(S30). 세라믹 분말과 유기 결합제의 혼합체를 금형 내로 사출하여 형성된 것을 생성형체(Green Body)라 한다.Next, using the injection molding machine to form a production body in which the plug shell and the plug insulator are integrated (S30). What is formed by injecting a mixture of ceramic powder and an organic binder into a mold is called a green body.
다음, 플러그 쉘과 플러그 인슐레이터가 일체화된 생성형체에서 유기결합제를 제거하여 탈지체를 만든다(S40). 생성형체에서 유기결합제를 제거하는 방법으로는 용매를 이용하는 용매추출이나 가열에 의한 가열탈지 혹은 이들을 조합한 방법이 이용될 수 있다.Next, the degreasing body is made by removing the organic binder from the formed product in which the plug shell and the plug insulator are integrated (S40). As a method of removing the organic binder from the resulting body, a solvent extraction using a solvent, heat degreasing by heating, or a combination thereof may be used.
다음, 탈지체를 소결한다(S50). 즉, 탈지체를 노(爐)에 넣고 적정 온도로 가열 및 유지시켜 분말 간의 치밀화를 통한 수축이 되도록 한다. 이 과정을 거쳐 부품의 밀도를 높이는 동시에 최종 부품의 형성을 얻을 수 있다.Next, the degreasing body is sintered (S50). That is, the degreasing body is placed in a furnace and heated and maintained at an appropriate temperature so as to be contracted through densification between powders. Through this process, the density of the parts can be increased and the formation of the final parts can be obtained.
다음, 소결체에 플러그 컨택트를 결합한다(S60). 플러그 컨택트의 일측면에는 고정돌기가 형성되어 있는 것이 바람직하다. 플러그 컨택트의 일측면에 고정돌기가 형성되어 있으므로, 플러그 컨택트가 성형물에 삽입된 후 유동하지 않는다. 따라서, 커넥터 플러그와 리셉터클 커넥터간의 전기적 접촉이 양호하게 된다. 한편, 플러그 컨택트를 소결체에 결합할 때, 래치도 함께 결합할 수 있다.Next, the plug contacts to the sintered body (S60). It is preferable that a fixing protrusion is formed on one side of the plug contact. Since a fixing protrusion is formed on one side of the plug contact, the plug contact does not flow after being inserted into the molding. Thus, the electrical contact between the connector plug and the receptacle connector is good. On the other hand, when coupling the plug contact to the sintered body, the latch can also be coupled together.
위와 같은 제조방법을 따르면, 세라믹 분말에 색상을 내는 안료를 첨가하여 플러그 쉘을 유색으로 제조할 수 있다. 따라서 커넥터 플러그의 디자인성이 향상된다. 또한, 플러그 인슐레이터와 플러그 쉘이 세라믹 재질을 이용하여 일체로 형성되므로, 플러그 커넥터의 내구성이 향상된다. 게다가, 세라믹은 자기 윤활성을 가지므로 플러그 커넥터를 리셉터클 커넥터에 장탈착하는 과정에서 플러그 쉘과 휴대용 전자기기가 마찰되어 손상되는 것이 방지된다. 그리고 장탈착 시에 마찰력이 감소되므로 삽입 작업이 용이해진다. 또한 플러그 인슐레이터와 플러그 쉘을 일체로 형성하므로, 제조과정도 간소화된다. 뿐만 아니라 종래의 플러그 커넥터를 리셉터클 커넥터에 장착하면 플러그 커넥터의 금속 쉘에 의해 휴대용 전자기기의 수신 감도가 저하될 수 있으나 본 발명의 일 양상에 따른 플러그 커넥터 제조방법을 따라 제작된 플러그 커넥터는 쉘이 세라믹 재질로 이루어져 있으므로 휴대용 전자기기의 수신 감도에 영향을 미치지 않아 휴대용 전자기기의 수신감도가 상대적으로 향상된다.According to the above manufacturing method, it is possible to manufacture a plug shell colored by adding a pigment that gives a color to the ceramic powder. Therefore, the design of the connector plug is improved. In addition, since the plug insulator and the plug shell are integrally formed using a ceramic material, the durability of the plug connector is improved. In addition, the ceramic is self-lubricating, so that the plug shell and the portable electronic device are prevented from being damaged by friction in the process of attaching and detaching the plug connector to the receptacle connector. And since the frictional force is reduced at the time of desorption, insertion work becomes easier. In addition, since the plug insulator and the plug shell are integrally formed, the manufacturing process is simplified. In addition, when the conventional plug connector is mounted on the receptacle connector, the reception sensitivity of the portable electronic device may be reduced by the metal shell of the plug connector. However, the plug connector manufactured according to the plug connector manufacturing method according to an aspect of the present invention may have a shell. Since the ceramic material does not affect the reception sensitivity of the portable electronic device, the reception sensitivity of the portable electronic device is relatively improved.
