Description

마이크로폰의 접속핀{Pin type Connecter of microphone}Pin type Connecter of microphone

본 발명은 마이크로폰의 접속핀에 관한 것으로서, 보다 상세하게는 강도가 보강되면서도 회로패턴의 손상을 줄일 수 있고, 솔더링된 후에는 더 견고하게 고정되도록 된 마이크로폰의 접속핀에 관한 것이다.The present invention relates to a connection pin of a microphone, and more particularly, to a connection pin of a microphone that can reduce damage to a circuit pattern while being reinforced, and more firmly fixed after being soldered.

근래, 일반인에게 널리 보급되고 있는 휴대폰, 캠코더 등과 같은 전자제품들은 소비자의 요구에 부응하여 갈수록 그 크기가 소형화되고 있는 추세이다. 이에 따라, 각종 전자제품에 사용되는 부품들도 그 기능을 동일하게 유지하거나 더 향상시키면서도 경박단소한 외형을 갖도록 활발히 개발되고 있다. 이러한 전자제품 가운데, 셀룰러 폰과 같은 이동 무선기기에는 음파를 전기적 신호로 변환해주기 위한 마이크로폰이 사용되는데, 이러한 마이크로폰 역시 경박단소한 외형을 가지도록 개발되어 왔다.Recently, electronic products such as mobile phones and camcorders, which are widely used by the general public, are becoming smaller in size in response to consumer demand. Accordingly, components used in various electronic products have also been actively developed to have a light and simple appearance while maintaining or improving the same function thereof. Among these electronic products, microphones for converting sound waves into electrical signals are used in mobile wireless devices such as cellular phones, and these microphones have also been developed to have a light and thin appearance.

도 1은 종래 마이크로폰의 분리사시도이고, 도 2는 종래 마이크로폰 접속핀의 솔더링부를 확대 도시한 평면도이다. 이를 참조하면, 상기 마이크로폰은 케이스(17) 내부에 음파의 진동에 따라 전기적인 신호로 변환해주기 위한 각종 소자(16)들이 구비되고, 이 소자(16)로부터 발생된 전기적인 신호는 인쇄회로기판(10)에 솔더링된 접속핀(40)을 통해 외부의 기판(30)에 전달되도록 구성된다.1 is an exploded perspective view of a conventional microphone, Figure 2 is an enlarged plan view showing a soldering portion of a conventional microphone connecting pin. Referring to this, the microphone is provided with various elements 16 for converting into an electrical signal according to the vibration of sound waves in the case 17, the electrical signal generated from the element 16 is a printed circuit board ( It is configured to be transferred to the external substrate 30 through the connecting pin 40 soldered to 10).

이중, 상기 인쇄회로기판(10)에는 다양한 기능을 하는 소자(16)들이 실장되며, 이 소자(16)들은 회로패턴(14)을 통해 상기 접속핀(40)과 연결되어 외부의 기판(30)에 전기적인 신호를 전달게 된다. 이를 위해, 상기 인쇄회로기판(30)에는 접속핀(40)이 결합되는 핀홀(13)이 형성되고, 이 핀홀(13)의 둘레에는 각종 소자(16)와 연결되는 회로패턴(14)이 형성되어 이 회로패턴(14)과 상기 접속핀(40)이 솔더링되어 상호 접속된다.Among these, the printed circuit board 10 is mounted with elements 16 having various functions, which are connected to the connection pin 40 through the circuit pattern 14 to the external substrate 30. An electrical signal is transmitted to the To this end, the printed circuit board 30 is formed with a pinhole 13 to which the connecting pin 40 is coupled, and a circuit pattern 14 connected to various elements 16 is formed around the pinhole 13. Thus, the circuit pattern 14 and the connecting pin 40 are soldered and interconnected.

이와 같이, 상기 접속핀(40)을 인쇄회로기판(10)에 솔더링하기 위해서는 상기 접속핀(40)을 유동되지 않도록 인쇄회로기판(10)의 핀홀(13)에 임시로 고정하여야 한다. 이를 위해 종래에는, 원주형 접속핀(40)의 솔더링부(42) 외주면에 다수개의 돌기(43)를 형성하여 이 돌기(43)가 인쇄회로기판의 핀홀(13) 내벽면을 파고들어 억지끼움되므로써, 임시 고정되도록 하였다.As such, in order to solder the connection pin 40 to the printed circuit board 10, the connection pin 40 must be temporarily fixed to the pinhole 13 of the printed circuit board 10 so as not to flow. To this end, conventionally, a plurality of protrusions 43 are formed on the outer circumferential surface of the soldering portion 42 of the columnar connecting pin 40 so that the protrusions 43 penetrate the inner wall surface of the pinhole 13 of the printed circuit board. As a result, it was temporarily fixed.

그러나, 이러한 방식의 접속핀 결합구조는 상기 접속핀(40)을 인쇄회로기판(10)의 핀홀(13)에 끼워넣게 되면, 접속핀(40)의 돌기(43)가 핀홀(13)의 내벽면을 파고들면서 핀홀(13)은 물론, 이 핀홀(13) 둘레의 회로패턴(14)을 함께 손상시켜 회로패턴(14)을 단락시키게 되는 문제점이 있다.However, in this type of connecting pin coupling structure, when the connecting pin 40 is inserted into the pinhole 13 of the printed circuit board 10, the protrusion 43 of the connecting pin 40 is formed in the pinhole 13. There is a problem that shorting the circuit pattern 14 by damaging the circuit pattern 14 around the pinhole 13 as well as the pinhole 13 while digging into the wall surface.

또한, 상기 접속핀(40)은 핀홀(13)과 접속핀(40) 사이의 갭(G)이 협소하여 솔더링시 용융액이 이 갭(G)으로 제대로 침투되지 못하여 솔더링 후에도 견고하게 고정되지 못하고 쉽게 분리되어 제품의 신뢰성이 저하되는 문제점이 있다.In addition, the connection pin 40 has a narrow gap (G) between the pinhole 13 and the connection pin 40, the melt does not penetrate properly into the gap (G) during soldering, it is difficult to be firmly fixed even after soldering There is a problem in that the reliability of the product is separated.

그렇다고 하여, 상기 접속핀(40)의 직경을 줄여 갭(G)을 확장시킬 경우 외부의 기판(30)에 접속할 때 접속핀(40)이 쉽게 휘어지거나 부러지기 때문에, 적당한 강도를 유지하기 위해서는 소정직경 이상으로 제한하여야 하며, 반대로 상기 인쇄회로기판(10)의 핀홀(13)은 마이크로폰의 전체 사이즈를 감안하여 일정사이즈 이상으로 크게 할 수 없는 바, 상기 접속핀(40)과 핀홀(13) 사이의 갭(G)을 크게 하기 어려운 문제점이 상존하였다.However, when the diameter of the connection pin 40 is reduced to expand the gap G, the connection pin 40 is easily bent or broken when connected to the external substrate 30. The pinhole 13 of the printed circuit board 10 cannot be larger than a predetermined size in consideration of the overall size of the microphone, and thus, between the connecting pin 40 and the pinhole 13. There existed the problem which is hard to enlarge the gap G of.

본 발명은 전술한 바와 같은 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 강도가 보강되면서도 회로패턴의 손상을 줄일 수 있고, 솔더링된 후에는 더 견고하게 고정되도록 된 마이크로폰의 접속핀을 제공하는 것이다.SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a connection pin of a microphone which is capable of reducing damage to a circuit pattern while reinforcing strength and being more firmly fixed after being soldered. .

이하, 본 발명의 바람직한 실시예를 첨부한 도면에 의거하여 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

도 3과 도 4는 각각 본 발명에 따른 마이크로폰의 분리사시도와, 솔더링부를 확대 도시한 평면도이다. 이를 참조하면, 상기 마이크로폰의 접속핀은 인쇄회로기판(10)의 핀홀(13)보다 다소 큰 직경의 원주형으로 이루어지며, 그 일측 외주면에는 다각형을 이루도록 가압 성형된 솔더링부(23)가 구비되어 이 솔더링부(23)가 상기 핀홀(13)에 끼워져 임시 고정되도록 구성된다.3 and 4 are respectively an exploded perspective view of the microphone according to the present invention, an enlarged plan view of the soldering portion. Referring to this, the connecting pin of the microphone is made of a cylindrical shape of a somewhat larger diameter than the pinhole 13 of the printed circuit board 10, one side of the outer peripheral surface is provided with a soldering portion 23 pressure-molded to form a polygon This soldering portion 23 is configured to be temporarily fixed to the pinhole (13).

상기 접속핀(20)은 길이가 긴 와이어형 부재에 소정간격으로 취약부를 형성하여 이 취약부를 중심으로 절단하게 되면, 개별적인 접속핀(20)이 얻어지게 된다. 이렇게 개별화된 접속핀(20)은 핀홀(13)의 직경보다 다소 큰 직경의 원주형 부재로서, 그 일측에는 대략 4각을 이루도록 가압 성형된 솔더링부(23)가 구비된다. 이 솔더링부(23)는 도4에서와 같이, 서로 대향된 모서리(22a,22b)를 잇는 대각선의 길이가 핀홀(13)의 직경보다 조금 크게 형성되어 이 모서리(22a,22b)가 핀홀(13)에 다소 억지끼움되어 임시 고정되도록 구성된다. 또한, 상기 접속핀(20)의 양단에는 테이퍼부(24)가 형성되어 인쇄회로기판(10)의 핀홀(13)에 용이하게 끼워넣을 수 있도록 구성된다.즉, 상기 다각형 솔더링부(23)의 각각의 모서리(22a,22b)를 잇는 가상의 외접원(E) 직경은 핀홀(13)의 내경보다 상대적으로 크게 형성되어 상기 솔더링부(23)의 모서리(22a,22b)가 핀홀(13)의 내벽면을 파고들어 솔더링 동안 임시 고정되도록 구성됨과 더불어, 상기 다각형 솔더링부(23)에 내접되는 가상의 내접원(I) 직경은 핀홀(13)의 내경보다 상대적으로 작게 형성되어, 핀홀(13)과 다각형 솔더링부(23) 사이의 갭(G)으로 솔더링 용융액이 원활하게 침투될 수 있도록 구성된다.When the connecting pin 20 forms a weak part in a long wire-like member at a predetermined interval and cuts it around the weak part, an individual connecting pin 20 is obtained. The connection pins 20 separated as described above are columnar members having a diameter slightly larger than the diameter of the pinholes 13, and one side of the connecting pins 20 is provided with a soldering part 23 press-molded to form approximately four angles. As shown in Fig. 4, the soldering portion 23 has a diagonal length connecting the opposing edges 22a and 22b slightly larger than the diameter of the pinhole 13 so that the edges 22a and 22b are pinholes 13 It is configured to be temporarily fixed by being slightly clamped on). In addition, a tapered portion 24 is formed at both ends of the connecting pin 20 so that the tape pin 24 can be easily inserted into the pinhole 13 of the printed circuit board 10. That is, the polygonal soldering portion 23 of the The imaginary circumscribed circle E connecting the corners 22a and 22b is formed to be larger than the inner diameter of the pinhole 13 so that the edges 22a and 22b of the soldering portion 23 are formed in the pinhole 13. In addition, the diameter of the virtual inscribed circle (I) inscribed in the polygonal soldering portion 23 is formed to be smaller than the inner diameter of the pinhole 13, and is configured to be temporarily fixed during soldering. The soldering melt is smoothly penetrated into the gap G between the soldering portions 23.

따라서, 이상의 구성에 의한 마이크로폰의 접속핀(20)은 그 직경이 핀홀(13)보다 다소 크게 형성되어, 종래의 접속핀에 비해 그 직경이 커지게 됨에 따라 강도가 보강되어, 외부의 기판(30)에 접속할 때 쉽게 부러지거나 휘어지지 않아 제품의 신뢰성이 향상된다.Therefore, the connecting pin 20 of the microphone according to the above configuration has a diameter slightly larger than that of the pinhole 13, and as the diameter thereof becomes larger than that of the conventional connecting pin, the strength is reinforced and the external substrate 30 ) Is not easily broken or bent when connected to the product, which improves the reliability of the product.

또한, 상기 접속핀(20)은 그 일측의 솔더링부(23)가 대략 4각을 이루도록 압착 성형되므로, 핀홀(13)과 접속핀(20) 사이의 갭(G)이 종래의 원주형 솔더링부에 비해 더 커지게 되므로, 솔더링시 용융액이 이 갭(G)을 통해 원활하게 침투되어 견고하게 솔더링된다.In addition, since the connecting pin 20 is press-molded so that the soldering part 23 on one side thereof forms an approximately four angle, the gap G between the pinhole 13 and the connecting pin 20 is a conventional cylindrical soldering part. Since it becomes larger than, the molten liquid penetrates smoothly through this gap G and is soldered firmly.

그 외에도, 상기 접속핀(20)은 솔더링부(23)의 모서리만(22)이 핀홀(13)의 내벽면에 억지끼움되도록 솔더링부(23)의 사이즈를 조절하여 성형할 수 있으므로, 인쇄회로기판의 핀홀(13) 및 이 핀홀(13) 둘레의 회로패턴(14)이 손상되는 것을 줄일 수 있다.In addition, the connection pin 20 may be molded by adjusting the size of the soldering portion 23 so that only the edge 22 of the soldering portion 23 is fitted to the inner wall surface of the pinhole 13, and thus, a printed circuit. Damage to the pinhole 13 of the substrate and the circuit pattern 14 around the pinhole 13 can be reduced.

이상에서와 같이 본 발명에 의하면, 상기 접속핀(20)은 종래의 접속핀에 비해 그 직경이 커져 강도가 보강되므로 외부의 기판(30)에 접속할 때 쉽게 휘어지거나 부러지지 않게 되며, 솔더링부(23)의 사이즈를 자유롭게 조절할 수 있어 핀홀(13)과 회로패턴(14)의 손상을 줄일 수 있고, 접속핀(20)과 핀홀(13) 사이의 갭(G)이 증가되어 더욱 견고하게 솔더링되는 장점이 있다.As described above, according to the present invention, since the diameter of the connection pin 20 is larger than that of the conventional connection pin, the strength is reinforced, so that the connection pin 20 does not easily bend or break when connected to the external substrate 30, and the soldering part 23 ) Can freely adjust the size of the pinhole 13 and the circuit pattern 14 to reduce the damage, the gap (G) between the connecting pin 20 and the pinhole 13 is increased to more robust soldering There is this.
