도1a 내지 도2에서 보는 바와 같이 종래 홀더가 구비된 케이블(100)은 일단부에 장치와 전기적으로 접속하기 위한 단자(111)가 형성된 홀더(110)와, 일단부가 홀더(110)에 삽입되어 단자(111)와 전기적으로 연결되는 다수의 와이어가 구비된 케이블(120) 및 홀더(110)와 케이블(120)의 연결부위 외측에 배치되어 이를 차폐하는 중공의 몰딩부(130)로 구성되는데, 도2를 참조하여 이들을 이용하여 홀더가 구비된 케이블(120)의 제조방법을 살펴보면 다음과 같다.As shown in Figures 1a to 2, the cable 100 provided with the conventional holder is a holder 110 having a terminal 111 for electrically connecting to a device at one end, and one end is inserted into the holder 110 It is composed of a cable 120 provided with a plurality of wires electrically connected to the terminal 111 and a hollow molding part 130 disposed outside the connection part of the holder 110 and the cable 120 and shielding them, Referring to Figure 2 to look at the manufacturing method of the cable 120 is provided with a holder using them as follows.

먼저, 홀더(110)와, 케이블(120) 및 몰딩부(130)를 준비(S110)하고, 케이블(120)의 와이어를 홀더(110)의 후단부에 형성된 홀을 통해 삽입하여 케이블(120)을 홀더(110)에 연결(S120)하고, 이들 연결부위에 에폭시(E)를 1차 도포(S130)한다.First, the holder 110, the cable 120 and the molding part 130 are prepared (S110), and the wire of the cable 120 is inserted through a hole formed in the rear end of the holder 110 to thereby cable 120 Is connected to the holder 110 (S120), and the epoxy (E) is first applied to these connecting parts (S130).

다음, 이를 상온에서 24시간 1차 건조하여 에폭시(E)를 경화(S140)하고, 몰딩부(130)의 중공 내에 홀더(110)와 케이블(120)의 연결부위를 배치(S150)한 후 몰딩부(130)의 선단부를 통해 중공 내에 에폭시(E) 2차 도포(S160)하여 몰딩부(130)와 홀더(110) 및 케이블(120)의 일측을 상호 연결한다.Next, it is first dried at room temperature for 24 hours to cure the epoxy (E) (S140), and then place the connecting portion of the holder 110 and the cable 120 in the hollow of the molding unit 130 (S150). Epoxy (E) secondary coating (S160) in the hollow through the front end of the part 130 to interconnect the molding part 130 with one side of the holder 110 and the cable 120.

이후, 이를 다시 상온에서 24시간 2차 건조하여 몰딩부(130)의 중공 내의 에폭시(E)가 경화되도록 한다.(S170)Subsequently, this is again dried at room temperature for 24 hours, so that the epoxy (E) in the hollow of the molding unit 130 is cured. (S170)

에폭시(E) 경화가 완료되면, 다시 몰딩부(130)의 후단부와, 케이블(120) 일측에 에폭시(E)를 3차 도포(S180)하고, 이를 상온에서 24시간 건조하여 3차 도포된 에폭시(E)를 경화(S190)한 후 제조된 케이블(120)을 외부로 반출한다.When the epoxy (E) curing is completed, a third coating (S180) of epoxy (E) is applied to the back end of the molding unit 130 and one side of the cable 120 (S180), and dried at room temperature for 24 hours to apply the third coating. After curing the epoxy (E) (S190), the manufactured cable 120 is taken out.

그러나, 상기한 종래의 케이블(120) 제조방법은 케이블(120)과 홀더(110)의 연결부위에 에폭시(E)를 도포하는 경우 에폭시(E) 일부가 외부로 노출된 단자(111)방향으로 흘러 에폭시(E)에 의해 단자(111)가 오염되면서 불량률이 크게 증가하는 문제점이 있었다.However, the above-described conventional method for manufacturing the cable 120 applies the epoxy (E) to the connecting portion of the cable 120 and the holder 110 in the direction of the terminal 111 where a part of the epoxy (E) is exposed to the outside. There was a problem in that the defect rate is greatly increased as the terminal 111 is contaminated by flowing epoxy (E).

또한, 종래의 케이블(120) 제조방법은 제조과정에서 연결핀과 와이어의 결합부위를 고정하고, 연결핀과 와이어의 결합부위를 차폐하는 몰딩부(130)의 결합위치가 견고하게 유지될 수 있도록 제조과정에서 총 3차례의 에폭시(E) 도포작업이 이루어지고, 도포된 에폭시(E)를 경화하기 위해 24시간의 건조과정이 총 3차례 이루어지면서 그 제조시간에 상당한 시간이 요구되는 바 생산량이 크게 저하될 뿐 아니라 이에 따른 인건비가 상승하면서 제조단가 상승의 원인이 되는 문제점이 있었다.In addition, the conventional method of manufacturing the cable 120 secures the connection portion between the connection pin and the wire during the manufacturing process, and ensures that the connection position of the molding portion 130 shielding the connection portion between the connection pin and the wire can be maintained firmly. In the manufacturing process, a total of three epoxy (E) coating operations are performed, and in order to cure the applied epoxy (E), a drying process of 24 hours is performed three times, and a considerable amount of time is required for the manufacturing time. Not only was it significantly lowered, there was a problem that the manufacturing cost increased as the labor cost increased.

도8은 본 발명의 다른 실시예에 따른 홀더에 차폐블럭이 결합된 상태를 도시한 도면이며, 도9는 본 발명의 다른 실시예에 따른 차폐블럭에 의해 사출용액이 단자방향으로 이동되는 것을 차단하는 상태를 도시한 도면이다.8 is a view showing a state in which the shielding block is coupled to the holder according to another embodiment of the present invention, and FIG. 9 is blocking the movement of the injection solution in the terminal direction by the shielding block according to another embodiment of the present invention It is a diagram showing a state.

도8 및 도9 실시예의 기본적인 구성은 도2 내지 도6의 실시예와 동일하나, 에폭시 도포 또는 인서트 사출시 에폭시 또는 사출용액이 단자방향으로 이동되는 것을 방지함으로써 단자 오염에 따른 불량률이 증대되는 것을 미연에 방지할 수 있는 구조로 형성된 것이다.The basic configuration of the embodiment of FIGS. 8 and 9 is the same as the embodiment of FIGS. 2 to 6, but the defect rate due to terminal contamination is increased by preventing the epoxy or the injection solution from moving in the terminal direction when the epoxy is applied or the insert is injected. It is formed in a structure that can be prevented.

본 실시예는 전 실시예와 달리 연결핀(13)과 와이어(21)를 연결하기 전에 홀더(10)의 타단부 중 연장선과 와이어(21)의 연결부위 전단에 차폐블럭(40)을 결합하는 단계를 더 포함하여 이루어진다.In this embodiment, unlike the previous embodiment, before connecting the connecting pin 13 and the wire 21, the shielding block 40 is coupled to the front end of the connecting portion of the extension wire and the wire 21 among the other ends of the holder 10. It further comprises a step.

여기서, 차폐블럭(40)은 연결핀(13)과 대응되는 일측에 다수의 통과공(41)이 형성된 플레이트 형상으로 형성되고, 상기한 통과공(41)에 각 연결핀(13)이 삽입된 후 홀더(10)의 타단부에 납땜되어 결합된다.Here, the shielding block 40 is formed in a plate shape in which a plurality of through holes 41 are formed on one side corresponding to the connection pins 13, and each of the connection pins 13 is inserted into the through holes 41 described above. After being soldered and coupled to the other end of the holder 10.

이러한 차폐블럭(40)은 에폭시를 도포하는 단계 또는 인서트 사출하는 단계에서 단자가 위치하는 공간과 에폭시 또는 사출용액이 주입되는 공간을 구획함으로써 단자방향으로 에폭시 또는 사출용액이 이동되는 것을 방지하여 이들로 인한 단자의 오염을 방지하는 역할을 한다.The shielding block 40 prevents the epoxy or injection solution from being moved in the terminal direction by dividing the space where the terminal is located and the space where the epoxy or injection solution is injected in the step of applying or inserting epoxy. It serves to prevent contamination of the terminal.

즉, 본 실시예에서는 차폐블럭(40)을 통해 에폭시 또는 사출용액의 이동을 차단함으로써 에폭시 또는 사출용액을 조심스럽게 도포할 필요가 없는 바 그 제조시간을 보다 단축할 수 있을 뿐 아니라 단자 오염에 따른 불량률을 크게 줄일 수 있는 특징을 갖는다.That is, in the present embodiment, by blocking the movement of the epoxy or injection solution through the shielding block 40, it is not necessary to carefully apply the epoxy or injection solution, and thus the manufacturing time can be shortened and the terminal contamination may be reduced. It has a feature that can significantly reduce the defect rate.

그 외의 구조는 전술한 기본 실시예와 동일하므로 나머지 설명은 생략하기로 한다.Other structures are the same as the above-described basic embodiment, and the rest of the description will be omitted.
