도 3 및 도 4에 도시된 바와 같이, 본 발명의 배선용 압착단자(100)는 압착부(110)와, 접속부(120)와, 나사체결부(130)로 크게 구성된다.As shown in FIGS. 3 and 4, the wire crimp terminal 100 of the present invention is largely composed of a crimping part 110, a connecting part 120, and a screw fastening part 130.

상기 압착부(110)는 피복전선(C)의 수용이 가능하도록 일정 내경을 가진 수평파이프 형상으로 이루어진다.The crimping unit 110 is formed in a horizontal pipe shape having a predetermined inner diameter to accommodate the coated wire C.

그리고, 상기 접속부(120)는 압착부(110)의 바닥면으로부터 수평으로 연장형성되며 중앙에 형성된 접속홀(121)을 가진다.In addition, the connection part 120 extends horizontally from the bottom surface of the crimping part 110 and has a connection hole 121 formed at the center thereof.

또한, 상기 나사체결부(130)는 상기 접속홀(121)의 가장자리를 따라 상부를 향해 연장형성된 플랜지 형태로 이루어지며 내주면에는 암나사산이 형성되어 있다.In addition, the screw fastening portion 130 is formed in the form of a flange extending toward the upper side along the edge of the connection hole 121 and the internal thread is formed with a female thread.

한편, 상기 암나사산은 나사체결부(130)의 높이를 최소화시키기 위해서 나사체결부(130)뿐만 아니라 접속홀(121)까지 형성되는 것이 바람직하다.On the other hand, the female thread is preferably formed not only the screw fastening portion 130 but also the connection hole 121 to minimize the height of the screw fastening portion 130.

이와 같은 구성의 배선용 압착단자(100)는 다음과 같이 제작된다.The wire crimp terminal 100 having such a configuration is manufactured as follows.

먼저, 얇은 금속판을 압착부(110)와 접속홀(121)이 형성된 접속부(120)를 갖도록 프레스 가공한 후, 피복전선(C)을 삽입시킬 수 있도록 상기 압착부(110)의 양단을 커얼링(curling) 가공하여 근접시킨 다음 근접된 압착부(110)의 양단을 용접시킨다.First, a thin metal plate is pressed to have a crimping part 110 and a connection part 120 having a connection hole 121 formed thereon, and then both ends of the crimping part 110 are inserted to insert the coated wire C. (curling) processing to close and then weld the both ends of the adjacent crimping portion (110).

그리고 상기 나사체결부(130)를 버링(burring) 가공을 통해 제작한다. 즉, 접속홀(121) 보다 큰 외경을 가진 펀치를 접속홀(121)에 밀어 넣어서 플랜지 형태로 제작한 후 탭가공을 하여 암나사산을 형성시키는 것이다.And the screw fastening portion 130 is produced through a burring (burring) process. That is, a punch having an outer diameter larger than that of the connection hole 121 is pushed into the connection hole 121 to be manufactured in the form of a flange, followed by tapping to form a female thread.

이와 같이 제조되는 본 발명의 배선용 압착단자(100)는 나사체결부(130)에 볼트(B)를 미리 체결시킨 상태에서 배선작업을 준비할 수 있게 되므로 실제 배선작업이 신속하고 간편하게 이루어질 수 있다.Since the wire crimping terminal 100 of the present invention manufactured as described above can prepare the wiring work in a state where the bolt B is fastened to the screw fastening portion 130 in advance, the actual wiring work can be made quickly and easily.

또한, 볼트(B)가 나사체결부(130)로부터 이탈되지 않기 때문에 천정 및 벽면의 배선작업이 매우 용이해질 뿐만 아니라 볼트(B)를 분실할 염려도 없다.In addition, since the bolt (B) is not separated from the screw fastening portion 130, wiring work of the ceiling and the wall surface becomes very easy, and there is no fear of losing the bolt (B).

특히, 볼트(B)의 머리부가 종래와 같이 접속부(120)에 밀착되지 않고 접속부(120)보다 상대적으로 접촉면적이 작은 나사체결부(130)의 상단에 밀착됨에 따라서 볼트(B)의 체결력이 나사체결부(130)의 상단으로 집중된다. 그 결과 볼트(B)의 체결력은 매우 강력해진다.In particular, as the head of the bolt (B) is not in close contact with the connecting portion 120 as in the prior art, the fastening force of the bolt (B) is in close contact with the upper end of the screw fastening portion 130 having a smaller contact area than the connecting portion 120 Concentrated to the top of the screw fastening portion 130. As a result, the fastening force of the bolt B becomes very strong.

한편 본 발명의 다른 실시예로서, 도 6 내지 도 9에 도시된 바와 같이, 상기 나사체결부(130)와 접속홀(121)의 내주면에는 나사체결부(130)와 접속홀(121)을 가로지르는 수직홈부(140)가 더 형성될 수 있다.Meanwhile, as another embodiment of the present invention, as shown in FIGS. 6 to 9, the screw fastening part 130 and the connection hole 121 are horizontally formed on the inner circumferential surface of the screw fastening part 130 and the connection hole 121. The vertical groove portion 140 may be further formed.

예컨대, 도 6 및 도 7에 도시된 바와 같이, 상기 수직홈부(140)는 서로 마주하는 한 쌍으로 형성될 수 있고, 도 9 및 도 10에 도시된 바와 같이, 십자형태로 마주하는 두 쌍으로 형성될 수도 있다.For example, as illustrated in FIGS. 6 and 7, the vertical grooves 140 may be formed in a pair facing each other, and as shown in FIGS. 9 and 10, in two pairs facing each other in a cross shape. It may be formed.

이와 동시에, 도 8에 도시된 바와 같이, 상기 접속홀(121) 및 나사체결부(130)는 암나사산의 골지름(d1)이 상기 볼트(B)의 바깥지름(d2)보다 작고 상기 볼트(B)의 골지름(d3) 보다는 크게 형성되도록 한다.At the same time, as shown in FIG. 8, the connection hole 121 and the screw fastening portion 130 have a female core thread diameter d1 smaller than an outer diameter d2 of the bolt B and the bolt ( Make it larger than the bone diameter (d3) of B).

이와 같이 구성되면 볼트(B)가 나사체결부(130)와 접속홀(121)에 나선결합될 때, 상기 볼트(B)가 나사체결부(130)와 접속홀(121)을 강제로 확장시키면서 체결된다. 만일, 암나사의 골지름(d1)이 볼트(B)의 골지름(d3) 보다 작게 되면 볼트(B)에 체결자체가 이루어지지 않게 되고, 암나사의 골지름(d1)이 볼트(B)의 바깥지름(d2)보다 크게 되면 강제확장이 발생되지 않게 된다.In this configuration, when the bolt B is helically coupled to the screw fastening part 130 and the connection hole 121, the bolt B is forcibly expanding the screw fastening part 130 and the connection hole 121. Is fastened. If the internal diameter of the female thread d1 is smaller than the central diameter d3 of the bolt B, the fastening itself is not made to the bolt B, and the internal diameter of the female thread d1 is outside the bolt B. If the diameter is larger than d2, the forced expansion does not occur.

여기서 상기 수직홈부(140)는 나사체결부(130)와 접속홀(121)이 확장될 수 있는 여유공간을 제공하게 된다. 이에 따라서 볼트(B)의 체결력은 한층 더 강력해진다.In this case, the vertical groove portion 140 provides a free space in which the screw fastening portion 130 and the connection hole 121 can be expanded. As a result, the tightening force of the bolt B becomes even stronger.

이와 같이, 도면을 참조하여 본 발명의 바람직한 실시예에 대해 상술하였으나 본 발명은 전술한 실시예에 한정되지 않으며, 본 발명이 속하는 기술분야에서 통상의 지식을 가진자가 본 발명의 사상을 벗어나지 않고 변형 가능하며, 이러한 변형은 본 발명의 권리범위에 속할 것이다.As described above, preferred embodiments of the present invention are described above with reference to the drawings, but the present invention is not limited to the above-described embodiments, and those skilled in the art may modify the present invention without departing from the spirit of the present invention.
