본 고안은 방수용 조인트 팩구조에 관한 것으로서, 보다 상세하게는 주전원 선과 분기선의 심선을 꼬아 통전하기 위한 연결부를 고온용 핫멜트가 도포된 열수축 튜브로 커버링함으로써, 원가절감 및 안정된 품질을 확보하는 방수용 조인트 팩구조에 관한 것이다.The present invention relates to a waterproof joint pack structure, and more particularly, a waterproof joint pack that secures cost reduction and stable quality by covering a connection part for twisting and energizing the main power wire and branch wires with a heat shrink tube coated with high temperature hot melt. It's about structure.

일반적으로, 자동차 배선은 주전원에 연결되어져 있는 전기, 전자부품(1개 또는 2개 이상)을 동시에 작동시킴과 동시에, 운전자가 작동여부를 확인할 수 있는 표시장치 등에도 전원을 공급하게 된다.In general, the automotive wiring operates electric and electronic components (one or two or more) connected to the main power supply at the same time, and also supplies power to a display device that allows the driver to check the operation.

이때, 주전원에서 공급되는 전원으로 2~3곳의 다른 위치에 있는 부품의 작동을 동시에 제어하기 위해서는 주전원선에 2~3개의 분기선을 연결해야만 한다.At this time, two to three branch lines must be connected to the main power line in order to simultaneously control the operation of components in two or three different locations with power supplied from the main power source.

이러한 연결구조에는 도 1에서 도시한 바와 같이 주전원선(10)의 일정부분을 스트립하여, 1~2개의 분기선(20)을 접합터미널(30)로 처리한 후 방수용 열수축 튜브(40)로 방수처리를 하는 방식이다.In this connection structure, as shown in FIG. 1, a predetermined portion of the main power line 10 is stripped, and one to two branch lines 20 are treated with the junction terminal 30 and then waterproofed with a waterproof heat shrink tube 40. This is how you do it.

상기 접합터미널(30)에 의한 연결구조에 의하면, 주전원선(10)의 일정구간을 중간 스트립 전용기를 이용하여 절연피복을 벗겨낸 다음, 분기선(20)과의 연결을 접합터미널(30)을 이용하여 반자동으로 압착한 후 방수용 열수축 튜브(40)로 방수처리한다.According to the connection structure by the junction terminal 30, the insulation coating is peeled off by using an intermediate strip dedicated machine for a certain section of the main power line 10, and then the connection with the branch line 20 is used by the junction terminal 30. After semi-automatic crimping to waterproof with a waterproof heat shrink tube (40).

그러나, 상기 접합터미널(30)을 이용한 구조는 대량생산 시에 안정된 품질을 보장하기 어렵고, 분기선(20)의 수가 4가닥 이상은 방수성능을 만족시키지 못하여 적용이 불가능한 문제점이 있다.However, the structure using the junction terminal 30 is difficult to ensure a stable quality during mass production, and the number of branch lines 20 is more than four strands there is a problem that can not be applied because it does not satisfy the waterproof performance.

이를 보완하기 위해 도 2에서 도시한 바와 같이 조인트 커넥터(50)를 이용하게 된다.In order to compensate for this, as shown in FIG. 2, a joint connector 50 is used.

It features.

상기 보조접착제(140)는 고온용 핫멜트(134)로 이루어진 링 형상의 접착제이며, 상기 주전원선(100)과 분기선(110) 중 어느 한 선에 끼워짐과 동시에 상기 열수축 튜브(130)의 내부에 구비되어 열수축 시 용융되어 접착제 역할을 하게 된다.The auxiliary adhesive 140 is a ring-shaped adhesive made of a high temperature hot melt 134, and is fitted to any one of the main power line 100 and the branch line 110 and at the same time inside the heat shrink tube 130 It is melted during heat shrinkage and serves as an adhesive.

이하, 본 고안에 따른 방수용 조인트 팩구조의 작용 및 효과를 설명하도록 한다.Hereinafter, the operation and effects of the waterproof joint pack structure according to the present invention.

우선, 링형상의 보조접착제(140)를 상기 주전원선(100)과 분기선(110) 중 어느 한 선에 끼운다.First, the ring-shaped auxiliary adhesive 140 is sandwiched between any one of the main power line 100 and the branch line 110.

그리고, 상기 주전원선(100)과 여러 가닥의 분기선(110) 끝단의 절연피복을 벗기고 노출된 심선을 꼬아 통전하기 위한 연결부(120)를 형성한다.In addition, the connection part 120 is formed to peel off the insulation coating at the ends of the main power line 100 and the branch lines 110 of several strands and twist the exposed core wire.

상기 연결부(120)측으로 상기 열수축 튜브(130)를 끼운다. 상기 열수축 튜브(130)는 일측에 개구부(132)를 형성하고 타측에는 밀폐됨으로써, 상기 연결부(120)를 커버링한다.The heat shrink tube 130 is inserted into the connection part 120. The heat shrink tube 130 forms an opening 132 on one side and is sealed on the other side, thereby covering the connection part 120.

이때, 상기 주전원선(100)과 분기선(110) 중 어느 한 선에 먼저 끼워진 보조접착제(140)는 상기 열수축 튜브(130)의 내측으로 삽입된다.At this time, the auxiliary adhesive 140 first inserted into any one of the main power line 100 and the branch line 110 is inserted into the heat shrink tube 130.

이후, 상기 열수축 튜브(130)를 열수축 장비로 수축시킨다. 상기 열수축 튜브(130)의 내측면에 도포된 고온용 핫멜트(134)에 의해 열수축 튜브(130)는 상기 연결부(120)에 수축됨과 동시에 접착되고, 상기 보조접착제 또한 용융되어 상기 주전원선(100)과 분기선(110) 사이의 공극을 없게하여 방수성능을 유지하게 된다.Thereafter, the heat shrink tube 130 is shrunk with heat shrink equipment.
