본 발명은 다수개의 전선을 프린트기판에 접속하는 전선접속방법에 관한 것으로, 특히 다수 피복전선의 심선자체를 핀상의 플러그로 가공하여 프린트기판과의 접속을 용이하게 할 수 있게한 피복선의 심선을 핀플러그로 사용하느 프린트기판의 전선접속방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire connection method for connecting a plurality of electric wires to a printed board. In particular, the core wire of the coated wire which makes the connection with the printed board easier by processing the core wire of the multiple coated wires with a pin-shaped plug. The present invention relates to a wire connection method of a printed board used as a plug.

일반적으로 여러개의 전선을 프린트기판의 접속공에 삽입하여 납땜고정하는 방법에는 전선자체의 심선을 직접 삽입하여 납땜하는 방법과 콘넥터를 이용하는 방법 즉, 제7도에 도시한 바와같이 다수개 전선(1)의 접속단부를 장방체상 하우징(2)에 연결설치하여 그 하우징(2)의 내부에는 박피된 각 전선(1)의 심선과 연결되는 접속편(3)을 설치하고, 이들 각 접속편(3)에는 별도의 지지체(4)에 고정된 접속핀(4)의 일단(4a)이 상기 하우징(2)의 하부에 형성된 삽입공을 통하여 삽입접속되게 한 다음, 결합된 지지체(5)의 하부로 노출되는 각 접속핀(3)의 타단(4b)을 통상의 프린트기판(20)에 형성된 접속공(21)에 삽입함과 아울러, 프린트기판(20)의 하부로 관출되는 각 접속핀(21)의 단부와 기판(20)저면에 형성된 동박부를 납땜으로 고정하는 방법등이 알려져 있다.In general, a method of inserting and soldering a plurality of electric wires into a connection hole of a printed circuit board includes a method of directly inserting and soldering a core wire of the wire itself and a method of using a connector, that is, a plurality of electric wires as shown in FIG. Is connected to the rectangular housing (2), and the connecting piece (3) connected to the core wire of each peeled wire (1) is provided inside the housing (2). ) Allows one end 4a of the connecting pin 4 fixed to a separate supporter 4 to be inserted through an insertion hole formed in the lower part of the housing 2, and then to the bottom of the joined supporter 5. The other end 4b of each of the exposed connecting pins 3 is inserted into the connecting hole 21 formed in the normal printed circuit board 20, and the connecting pins 21 are inserted into the lower portion of the printed board 20. The method of fixing the edge part of the edge part and the copper foil part formed in the bottom surface of the board | substrate 20 by soldering, etc. are known.

그러나, 이와같은 종래의 접속방법중, 전기한 바와같은 심선의 직접삽입방법은 다수개 전선의 심선부를 프린트기판의 각 접속공에 일일이 삽입하여야 하므로 많은 인력이 소요되어 생산성의 저하요인을 갖게될 뿐만아니라, 각 심선이 균일한 깊이로삽입되지 않음으로 인하여 전선과의 쇼트현상을 유발하게 됨으로써 제품의 불량요인을 배제할 수 없게되는 결함이 있으며, 후기의 콘넥터를 이용한 접속방법의 경우에는 번거로운 가공조립을 요하는 하우징(2)과 별도의 접속핀(4)을 가지는 지지체(5)를 각기 구비하여 이들을 일차적으로 결합하여야만 하므로 복잡한 체결구조에 따른 제조원가의 상승요인을 갖게됨은 물론, 외부로부터 가해지는 충격이나 진동등에 의하여 상호결합된 하우징(2)와 각 접속핀(3)과 각 접속핀(4)사이의 접속상태가 쉽게 이완 되거나 마모, 손상될 경우에는 확실하고 안정된 접속을 기할 수 없게되는 결함이 있었다.However, in such a conventional connection method, the direct insertion method of the core wires as described above requires inserting the core wire portions of a plurality of wires into each connection hole of the printed circuit board one by one, thus requiring a lot of manpower and reducing the productivity. In addition, each core wire is not inserted at a uniform depth, which causes short circuits with the wires. Therefore, defects of the product cannot be excluded. In the case of the connection method using a later connector, the cumbersome process assembly is required. Since the housing 2 and the support 5 having a separate connection pin 4 are required to be coupled to each other first, the housing 2 has a rising factor of manufacturing cost due to a complicated fastening structure, and an impact applied from the outside. The connection state between the housing 2 and each connecting pin 3 and each connecting pin 4 which are mutually coupled by vibration or vibration is easily relaxed. Or worn, there was a defect that can not talk to a solid and stable connection if damaged.

뿐만아니라, 하우징(2)과 지지체(5)가 가지는 자체형상 및 규격에 따라 상당한 점유공간을 필요로하게 되므로 제품의 소형화에 장애요인을 갖게되는 등의 결함과 문제점이 있었다.In addition, since a considerable occupied space is required according to its own shape and size of the housing 2 and the support 5, there are defects and problems, such as having obstacles to miniaturization of the product.

본 발명은 이와같은 종래의 결함과 문제점을 해소하기 위하여 창안한 것으로, 박피된 각 전선의 심선부를 납으로 피복도금하고 그 각 심선부위의 내측부를 합성수지등으로 몰드가공하여 몰드지지부재의 하부로 배열관출되는 도금심선부가 통상의 접속핀 플러그로 사용되게 함으로써 다수 전선의 접속구조를 단순화 할 수 있게 한 것인바, 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been devised to solve such a conventional defect and problems, and the coating of the core wires of each stripped wire with lead, and the inner portion of each core wire is molded by synthetic resin and arranged under the mold support member. The plated core wire to be used as a conventional connecting pin plug to simplify the connection structure of a plurality of wires, which will be described in detail by the accompanying drawings as follows.

제1도 내지 제4도는 본 발명 방법의 일실시예를 보인 것으로 이에 도시한 바와같이, 통상의 방법으로 박피된 피복전선(10)의 심선부(11)를 가열납조(13)에 용융된 납물(14)에 담그어(제2도 참조) 박피된 각 심선부(11)의 표면에 제6도에 도시한 바와같이 소정두께의 납(14')이 피복도금되게 한 다음, 소정간격으로 정렬된 일단(一團)의 전선(10)의 피복부(12)끝단에 합성수지재 절연지지부재(15)를 몰드가공으로 형성하여, 제3도에 도시한 바와같이 소정폭과 두께 및 길이를 가지는 장방체상 지지부재(15)의 하부에 도금된 심선부(11')가 일정길이로 배열설치되게하고, 이와같이 된 도금심선부(11')를 공지프린트기판(20)의 접속공(21)에 삽입접속시킨다음 기판(20)의 하부로 관출되는 각 도금심선부(11')의 단부를 기판(20) 저면의 동박부에 납땜고정하여 프린트기판(20)과 각 전선(10)과의 접속을 기하게 되는 것으로, 이때에 상기의 절열지지부지(15)를 형성함에 있어서, 몰드가공방법으로 함께 성형하는 대신에 제5도에 도시한 바와같이 다수의 삽착공(15a')이 일정간격으로 형성된 절연지지부재(15')를 별도로 형성하여 도금된 심선부(11) 및 피복부(12)를 압입고정할 수 도 있다.1 to 4 show one embodiment of the method of the present invention, as shown in the figure, the lead wire melted in the heating lead bath 13 in the core portion 11 of the coated wire 10 peeled by a conventional method Immersed in (14) (see FIG. 2), and the lead 14 'of a predetermined thickness is coated on the surface of each peeled core portion 11, as shown in FIG. 6, and then aligned at predetermined intervals. A rectangular resin having a predetermined width, thickness and length is formed by forming a synthetic resin insulating support member 15 at the end of the covering portion 12 of one end of the electric wire 10 by mold processing. The core wire portion 11 'plated on the lower portion of the upper support member 15 is arranged in a predetermined length, and the plated core wire portion 11' is thus inserted into the connection hole 21 of the known printed board 20. After the connection, the end of each of the plating core wire portions 11 ', which penetrates into the lower portion of the substrate 20, is soldered and fixed to the copper foil on the bottom surface of the substrate 20 so that the printed circuit board 20 and The connection with the electric wire 10 is to be made, and at this time, in forming the heat-retaining support site 15, instead of molding together by the mold processing method, as shown in FIG. 15a ') may separately form the insulating support member 15' having a predetermined interval to press-fit the plated core wire 11 and the cover 12.

이상에서 설명한 바와같은 본 발명 방법은 박피된 각 피복전선(10)의 심선부(11)를 납으로 피복도금하여 각 단위 심선간의 결속 및 심선부(11)자체의 강도를 보강하게함과 아울러 이와같이 된 다수개의 전선(10)이 단순지지부재(15또는 15')에 의하여 배열고정되게한 간단한 지지구조에 따라, 각 도금심선부(11') 자체가 각각의 핀플러그 역할을 가질 수 있게하여 프린트기판(20)의 접속공(21)과의 용이하고 확실한 접속을 기할 수 있게 함으로써, 종래의 접속방법이 가지는 제반결합 및 문제점을 배제하여 제조원가의 절감과 생산성의 향상을 꾀할 수 있게 하고 제품의 신뢰도를 높일 수 있으며, 접속부위가 차지하는 점유공간을 축소하여 제품의 소형화에 기여할 수 있게 되는 등의 여러가지 이점을 제공할 수가 있다.As described above, the method of the present invention coats the core portions 11 of each of the stripped sheathed wires with lead so as to reinforce the binding between the unit cores and the strength of the core portions 11 itself. According to a simple support structure in which a plurality of wires 10 are arranged and fixed by a simple support member 15 or 15 ', each plated core portion 11' itself can have a respective pin plug role to print. By allowing easy and reliable connection with the connection hole 21 of the substrate 20, it is possible to reduce manufacturing costs and improve productivity by eliminating all coupling and problems of the conventional connection method. In addition, the present invention can provide various advantages such as reducing the space occupied by the connection part and contributing to the miniaturization of the product.
