접속단자절연구조{ISOLATING STRUCTURE OF A CONNECTING TERMINAL}ISOLATING STRUCTURE OF A CONNECTING TERMINAL}

본 고안은 접속단자절연구조에 관한 것으로서, 특히 접속단자의 핀이 납땜되는 커넥터 몸체 부분에 관통공을 형성하여 전선을 납땜 연결하였을 때 발생되는 플럭스가 중첩되는 것을 방지함으로써 플럭스(flux)로 인한 누전이 발생되는 현상을 방지하는 효과를 갖는 접속단자절연구조에 관한 것이다.The present invention relates to a connection terminal insulation structure, and in particular, a through hole is formed in the connector body portion to which the pins of the connection terminal are soldered to prevent the flux generated when soldering the wires to be overlapped to prevent leakage due to flux. The present invention relates to a connection terminal insulating structure having an effect of preventing this phenomenon from occurring.

일반적으로 전기장판, 전기매트 등의 난방제품에 전원을 공급하여 열을 발생하기 위해 전원접속단자가 사용된다. In general, a power connection terminal is used to generate heat by supplying power to heating products such as electric blankets and mats.

도 1a 내지 도 1c에 예시된 바와 같이, 전원접속단자(1)는 전원을 공급하여 난방제품(9)에 발생 되는 열을 조절하도록 일측에 전원플러그(8)가 구비되고 타측에 커넥터(7)가 구비된 전원조절장치(6)가 연결된다.As illustrated in FIGS. 1A to 1C, the power connection terminal 1 is provided with a power plug 8 on one side and a connector 7 on the other side to supply power to regulate heat generated in the heating product 9. Is provided with a power regulator 6 is provided.

전원조절장치(6)의 커넥터(7)에 끼움 결합 되도록 전원접속단자(1)는 다수의 단자핀(1)이 결합된 단자몸체와, 단자몸체의 단자핀(1)에 고정된 전열선(4)을 보호하고 이물질이 침투되지 않도록 체결구멍(5)에 나사와 같은 체결수단으로 결합되는 커버(1-1)를 포함한다.In order to fit the connector 7 of the power regulator 6, the power connection terminal 1 has a terminal body having a plurality of terminal pins 1 coupled thereto, and a heating wire 4 fixed to the terminal pins 1 of the terminal body. ) And a cover 1-1 coupled to the fastening hole 5 by a fastening means such as a screw so as to protect the cover and prevent foreign substances from penetrating.

전원접속단자(1)는 또한 다수의 단자핀(1)에 전열선(4)이 결합되도록 전열 선(4)의 통과를 안내하는 안내구멍(2)이 형성된다.The power connection terminal 1 is also formed with a guide hole 2 for guiding the passage of the heating wire 4 so that the heating wire 4 is coupled to the plurality of terminal pins 1.

전기장판, 전기매트, 전기 찜질기 등에 열을 발생하도록 설치된 전열선(4)에 전원을 공급하기 위해 전원접속단자의 안내구멍(2)을 통해서 단자핀(1)에 전열선(4)을 각각 납땜 연결하여 고정한다.Solder the heating wires 4 to the terminal pins 1 through the guide holes 2 of the power connection terminals in order to supply power to the heating wires 4 installed to generate heat to the electric plate, the mat, and the electric steamer. Fix it.

그러나, 단자핀(1)과 전열선(4)의 납땜작업이 이루어질 때 단자핀(4) 납땜부 주변에 플럭스(flux)(3)가 발생 된다. 이 플럭스(3)는 단자핀(1)과 전열선(4)을 납땜 접합할 때 납땜 접합면의 산화를 방지하여 단자핀(1)과 전열선(4)의 납땜 접합이 완전하게 이루어지게 하는 역할을 하지만 단자핀(1) 주위로 퍼져서 흘러내린 플럭스(3)에는 이물질이 부착될 수 있다.However, when soldering of the terminal pin 1 and the heating wire 4 is performed, a flux 3 is generated around the soldering portion of the terminal pin 4. This flux (3) prevents oxidation of the solder joint surface when soldering the terminal pin (1) and the heating wire (4) serves to complete the solder joint of the terminal pin (1) and the heating wire (4). However, foreign matter may be attached to the flux 3 that flows around the terminal pin 1 and flows down.

따라서 단자핀(1)에서 흘러내려 주변으로 퍼진 플럭스(3)에 의해 단자핀(1) 사이의 절연이 확실히 이루어지지 않는 문제점이 발생 되었다.Therefore, a problem arises that the insulation between the terminal pins 1 is not secured by the flux 3 flowing down from the terminal pins 1 and spreading around.

본 고안은 상기의 종래 문제점을 해결하기 위해 개발된 것으로서, 단자핀과 접속핀의 납땜작업시에 발생되는 플럭스가 상호 접촉되지 않게 하여 단자핀 사이의 절연이 확실하게 이루어지는 접속단자절연구조를 제공하고자 하는 것이다.The present invention was developed to solve the above problems, and to provide a connection terminal insulation structure in which the flux generated during the soldering operation of the terminal pin and the connecting pin does not come into contact with each other to ensure the insulation between the terminal pins. It is.

본 고안의 접속단자절연구조는 통상의 단자핀이 고정되고, 전열선이 통과되는 안내구멍이 형성된 접속단자몸체에 있어서,In the connection terminal insulation structure of the present invention, in a connection terminal body in which a general terminal pin is fixed and a guide hole through which a heating wire passes is formed,

단자핀과 단자핀 사이에 관통구멍을 형성하여 단자핀이 절연구멍에 의해 이 격되게 구성함으로써 달성된다.This is achieved by forming a through hole between the terminal pin and the terminal pin so that the terminal pin is spaced apart by the insulating hole.

본 고안의 접속단자절연구조는 단자핀과 단자핀 사이에 형성된 절연구멍에 의해 단자핀과 전열선을 납땜할 때 발생되는 플럭스가 절연구멍 사이로 흘러서 단자핀과 단자핀 사이에 플럭스가 상호 접촉되어 연결되지 않으므로 단자핀 사이의 절연이 향상되는 효과를 갖는다.In the connection terminal insulating structure of the present invention, the flux generated when soldering the terminal pin and the heating wire by the insulating hole formed between the terminal pin and the terminal pin flows between the insulating holes so that the flux is not connected between the terminal pin and the terminal pin. Therefore, the insulation between the terminal pins is improved.

본 고안의 접속단자절연구조는 통상의 단자핀이 고정되고, 전열선이 통과되는 안내구멍이 형성된 접속단자몸체에 있어서,In the connection terminal insulation structure of the present invention, in a connection terminal body in which a general terminal pin is fixed and a guide hole through which a heating wire passes is formed,

단자핀과 단자핀 사이에 절연구멍을 형성하여 단자핀이 절연구멍에 의해 이격되게 구성된 것이 특징이다.An insulating hole is formed between the terminal pin and the terminal pin so that the terminal pin is spaced apart by the insulating hole.

이하 첨부도면을 참조하여 본 고안의 접속단자절연구조의 일 실시예를 더욱 상세히 설명한다.Hereinafter, an embodiment of a connection terminal insulating structure of the present invention will be described in detail with reference to the accompanying drawings.

도 2 내지 도 4에 예시된 바와 같이, 본 고안의 접속단자절연구조는 접속단자의 단자 몸체 구조를 개선한 것이다. As illustrated in FIGS. 2 to 4, the connection terminal insulation structure of the present invention improves the terminal body structure of the connection terminal.

본 고안의 접속단자절연구조를 구성하는 접속단자(10)는 통상의 단자핀(11)이 다수 개 고정되고, 이 단자핀(11)의 일측에 전열선(15)을 고정하도록 전열선이 관통되는 안내구멍(12)이 형성된다. In the connection terminal 10 constituting the connection terminal insulating structure of the present invention, a plurality of conventional terminal pins 11 are fixed, and a guide wire is passed through the heating wires so as to fix the heating wire 15 to one side of the terminal pins 11. The hole 12 is formed.

단자핀(11)과 단자핀(11) 사이에는 이들 단자핀(11)을 분리시켜서 납땜시에 발생되는 플럭스(16)가 흘러내리도록 절연구멍(13)이 형성된다. 이 절연구멍(13)은 플럭스(16)가 흘러내려 인접 단자핀(11)으로 흘러내리지 않도록 납땜 되는 단자핀(11)의 납땜부(11-1) 길이 이상으로 형성되는 것이 바람직하다.An insulating hole 13 is formed between the terminal pin 11 and the terminal pin 11 to separate the terminal pins 11 so that the flux 16 generated during soldering flows down. The insulating hole 13 is preferably formed to be longer than the soldering portion 11-1 of the terminal pin 11 to be soldered so that the flux 16 does not flow down to the adjacent terminal pin 11.

또한, 절연구멍(13) 하부에 단턱부(17)가 형성되는 것이 바람직하다.In addition, it is preferable that the stepped portion 17 is formed under the insulating hole 13.

단턱부(17)는 접속단자 외부로부터 내부로 이물질이 유입되는 것을 방지하도록 절연구멍(13)이 마감구(18)로 밀폐되는 것이 바람직하다.The stepped part 17 is preferably insulated from the end of the insulating hole 13 to prevent foreign matter from flowing into the inside of the connection terminal.

이와 달리 절연구멍(13)은 접속단자를 결합되는 커버(도시되지 않음)에 마감구를 돌출 형성하여 접속단자와 커버의 결합시에 절연구멍이 커버의 마감구로 밀폐되게 구성될 수 있다.In contrast, the insulating hole 13 may be configured to protrude a finishing hole in a cover (not shown) to which the connecting terminal is coupled so that the insulating hole is sealed by the closing hole of the cover when the connecting terminal and the cover are coupled to each other.

상기와 같이 구성된 본 고안의 접속단자절연구조를 구성하는 접속단자(10)는 전열선(15)이 안내구멍(12)을 통해서 단자핀(11)으로 안내되어 단자핀(11)에 접촉되게 한 상태에서 납땜작업을 한다.In the connection terminal 10 constituting the connection terminal insulating structure of the present invention configured as described above, the heating wire 15 is guided to the terminal pin 11 through the guide hole 12 to be in contact with the terminal pin 11. Soldering in

납땜작업시에 발생되는 플럭스(16)는 단자핀(11) 사이의 절연구멍(13)으로 흘러 경화된다.The flux 16 generated during the soldering operation flows into the insulating hole 13 between the terminal pins 11 and hardens.

따라서 절연구멍(13)으로 플럭스가 흘러내려도 플럭스에 의해 인접한 단자핀(11)이 상호 전기적으로 연결되지 않게 된다. 또한 절연구멍(13)에 의해 인접 단자핀(11)들이 이격되어 있으므로 이물질에 의해 단자핀(11)들이 상호 전기적으로 연결되는 것이 방지된다.Therefore, even though flux flows into the insulation hole 13, adjacent terminal pins 11 are not electrically connected to each other by the flux. In addition, since the adjacent terminal pins 11 are spaced apart by the insulating hole 13, the terminal pins 11 are prevented from being electrically connected to each other by foreign matter.

납땜작업이 완료되면 절연구멍(13) 하부의 단턱부(17)에 마감구(18)를 결합하여 절연구멍(13)을 밀폐하여 절연구멍(13)을 통해 접속단자 내부로 이물질이 침투되는 것을 방지한다. 납땜에 의해 연결된 단자핀(11)과 전열선(15)은 도시되지 않은 커버를 결합하여 밀폐시킨다.After the soldering operation is completed, the finishing hole 18 is coupled to the stepped portion 17 of the lower portion of the insulating hole 13 to seal the insulating hole 13 to allow foreign substances to penetrate into the connection terminal through the insulating hole 13. prevent. The terminal pin 11 and the heating wire 15 connected by soldering are sealed by combining a cover (not shown).

본 고안의 접속단자절연구조를 채택한 접속단자는 전기매트, 전기방석 등의 난방제품용 접속단자로 이용될 수 있고, 온도조절장치에 연결된 커넥터와 연결하여 전기플러그를 통하여 안전하게 사용할 수 있다.The connection terminal adopting the connection terminal insulation structure of the present invention can be used as a connection terminal for heating products such as electric mats and electric cushions, and can be used safely through an electric plug by connecting to a connector connected to a temperature control device.
