터미널 접속단자의 제조방법 및 그 제조방법에 의하여 제조된 터미널 접속단자{ A joint terminal }Manufacturing method of terminal connecting terminal and terminal connecting terminal manufactured by the manufacturing method {A joint terminal}

본 발명은 터미널 접속단자의 제조방법 및 그 제조방법에 의하여 제조된 터미널 접속단자에 관한 것으로, 더욱 구체적으로 설명하면, 접속시킬 전선의 두께에 비하여 터미널 접속단자의 압착접속부에 형성된 체결공이 통상적인 경우보다 큰 체결공이 요구될 경우에 전선의 규격보다 더 큰 금속제 파이프를 절단하고 절단된 파이프의 전선의 접속부분의 직경을 축소시켜 전선이 삽입고정되도록 하고 축소되지 않은 부분을 압축시켜 압착접속부의 접촉면적을 크게 압축시키고 여기에 요구되는 크기의 체결공을 천공하므로서 보다 큰 규격의 체결공을 천공하는 것이 가능한 터미널 접속단자의 제조방법 및 그 제조방법에 의하여 제조된 터미널 접속단자에 관한 것이다.The present invention relates to a method for manufacturing a terminal connection terminal and a terminal connection terminal manufactured by the manufacturing method, and more specifically, when the fastening hole formed in the crimp connection portion of the terminal connection terminal as compared to the thickness of the wire to be connected is common If larger fastening holes are required, cut the metal pipe larger than the size of the wire, reduce the diameter of the connection part of the wire of the cut pipe to fix the wire, and compress the unreduced part to compress the contact area of the crimp connection. The present invention relates to a method for manufacturing a terminal connection terminal capable of drilling a fastening hole of a larger standard by greatly compressing and drilling a fastening hole of a required size, and a terminal connection terminal manufactured by the method.

일반적으로, 종래의 터미널 접속단자(A')는, 도 1에 도시된 바와 같이, 소정두께의 전선관, 예를 들면, 직경 5.5mm의 전선관(E)의 단부(E1)에 접속고정되는 터미널 접속단자(A')는 원통형의 내경이 5.5mm의 고정단부(1)와 상기 고정단부(1)와 이어지며 약 10mm의 폭으로 압착된 압착접속부(2)의 중간에 5~6mm의 체결공(3)이 형성된 구조이다. In general, the conventional terminal connection terminal A 'is a terminal connection fixed to the end E1 of a conduit of a predetermined thickness, for example, a conduit E of 5.5 mm in diameter, as shown in FIG. The terminal A 'has a fastening hole of 5 to 6 mm in the middle of the crimp connection portion 2, which has a cylindrical inner diameter of 5.5 mm and is fixed to the fixed end portion 1 and the fixed end portion 1 and has a width of about 10 mm. 3) is a formed structure.

만일, 직경이 5.5mm의 전선관(E)을 터미널 접속단자(A')의 체결공(3)이 약 12mm의 크기가 요구될 경우에는 내경이 5.5mm의 금속제 원통관을 절단하고, 절단된 원통관의 일부분을 최대한 압축시켜서 고정단부(1)와 과도한 압력으로 압착된 압착접속부(2)를 형성하고, 이와 같이 형성된 압착접속부(2)에 체결공(3)을 천공하는 구조로 제조되어 사용되고 있다.If a diameter of 5.5 mm is required for the fastening hole 3 of the terminal connection terminal A 'to a diameter of 5.5 mm, a metal cylindrical tube with an inner diameter of 5.5 mm is cut and the cut circle A part of the clearance is compressed as much as possible to form a crimping connection part 2 pressed against the fixed end 1 and excessive pressure, and is manufactured and used in a structure for drilling the fastening hole 3 in the crimping connection part 2 thus formed. .

그러나, 이와 같이 과도한 압력으로 압착된 터미널 접속단자(A')는 압착접속부(2)가 필요한 두께의 이하로 과도하게 압착되게 되므로 너무나 약하게 되어 쉽게 파손이 되고 있는 실정이다. 그러지 않기 위해서는 내경이 조금 큰 내경이 약 10.5mm의 파이프를 사용하게 되면 접속이 필요한 압착접속부(2)는 적당한 강도를 유지할 수 있으나 5.5mm의 전선이 체결되기 위해서는 10.5mm의 내경의 금속제 원통관의 고정단부(1)는 전선관(E)이 삽입고정되기에는 너무 큰 직경을 가지므로 전선관(E)을 고정시킬 수 없게 되는 문제점이 있었다.However, the terminal connection terminal A 'squeezed by excessive pressure is excessively squeezed below the required thickness of the crimp connection part 2, and thus is too weak and easily damaged. In order not to do so, if the inner diameter is slightly larger than 10.5 mm, the crimp connection part 2, which needs to be connected, can maintain the appropriate strength, but in order for the 5.5 mm electric wire to be fastened, the 10.5 mm inner cylindrical metal tube The fixed end 1 has a problem that the conduit E cannot be fixed because the conduit E has a diameter too large to be inserted and fixed.

본 발명의 목적은, 이러한 문제점을 해결하기 위한 것으로, 소정두께의 전선관을 전선관의 두께에 적합한 고정단부를 갖는 직경으로 형성할 수 있으면서도 압착접속부의 크기도 사용에 필요한 적당한 크기로 형성시키는 것이 가능하게 되어 커다란 크기의 체결공을 전기안전규격에 적합하게 되므로 아무런 안전도에 대한 무리가 없이 형성하는 것이 가능하게 되어 제조 및 사용이 편리하게 된 터미널 접속단자의 제조방법 및 그 제조방법에 의하여 제조된 터미널 접속단자를 제공하는 것이다.SUMMARY OF THE INVENTION An object of the present invention is to solve such a problem, and it is possible to form a conduit of a predetermined thickness with a diameter having a fixed end suitable for the thickness of the conduit, but also to form a crimp connection portion with an appropriate size required for use.

본 발명의 제1실시예에 따른 터미널 접속단자의 제조방법은, 도 2에 도시된 바와 같이, 터미널 접속단자의 압착접속부의 체결공의 직경이 큰 직경의 체결공으로 형성될 경우에 압착접속부의 면적이 체결공의 크기가 나올 금속관을 선택하는 단계(S1)와, 상기 선택된 금속관을 상기 터미널 접속단자를 제조하는 일정길이로 절단하는 단계(S2)와, 이와 같이 절단된 금속관의 전선관이 고정될 고정단부를 전선관의 직경에 적합하게 직경을 축소하는 직경축소단계(S3)와, 축소가 되지 않는 금속관을 압착시켜 압착접속부를 형성하는 단계(S4)와, 상기 압착접속부상에 체결공을 형성시키는 단계(S5)를 포함한다. 이와 같은 제조과정을 통하여 큰 직경의 금속관에서 직경이 축소된 축경된 고정단부(1)와 큰 직경의 압착된 압착접속부(2)가 형성되고 상기 압착접속부(2)내에 체결공(3)이 형성된 본 발명에 따른 터미널 접속단자가 제조되게 되는 것이다.
본 발명의 제1실시예에 따른 상기 선택된 금속관을 터미널 접속단자로 제조하는 길이는 2개의 터미널 접속단자를 제조하는데 필요한 길이로 선택되었으나 1개의 터미널 접속단자의 길이로 선택될 수도 있을 것이다.In the method of manufacturing a terminal connection terminal according to the first embodiment of the present invention, as shown in FIG. Selecting a metal tube to the size of the fastening hole (S1), and cutting the selected metal tube to a predetermined length for manufacturing the terminal connection terminal (S2), and fixing the conduit of the metal tube cut in this way A diameter reduction step (S3) for reducing the diameter of the end to the diameter of the conduit, a step of forming a crimping connection by pressing the non-shrinkable metal tube (S4), and forming a fastening hole on the crimping connection (S5) is included. Through this manufacturing process, the reduced diameter fixed end portion 1 of the large diameter metal tube and the large diameter crimping crimping connection part 2 are formed, and the fastening hole 3 is formed in the crimping connection part 2. The terminal connection terminal according to the present invention is to be manufactured.
The length for manufacturing the selected metal tube as the terminal connection terminal according to the first embodiment of the present invention is selected as the length necessary for manufacturing the two terminal connection terminals, but may be selected as the length of one terminal connection terminal.

이와 같이 제조된 본 발명에 따른 터미널 접속단자(A)는 전선관(E)이 고정되는 고정단부(1)는 큰 크기의 금속관을 직경을 압축시켜서 직경을 작게 하므로 고정단부(1)의 두께가 동일한 고정단부의 직경을 갖는 종래의 터미널 접속단자의 고정단부의 두께보다 약 2배정도 두껍게 형성되므로 전선관(E)의 단부(E1)의 파지고정작업시 고정단부(1)상에 균열이 발생되지 않고, 고정단부(1)에 대한 파지고정작업의 안정성이 확보되게 되는 것이다. 즉, 종래의 직경이 5.5mm의 전선관(E)을 사용할 경우 내경이 5.5mm의 금속제 원통관이 사용되고 상기 금속제 원통관의 두께는 1mm이나, 본 발명에서는 직경 10.5mm의 금속제 원통관이 축경이 되므로 고정단부의 두께가 2mm에 근접하게 형성되게 되는 것이다.The terminal connection terminal (A) according to the present invention manufactured in this way is a fixed end portion (1) to which the conduit (E) is fixed is reduced in diameter by compressing the diameter of a large size metal tube to the same thickness of the fixed end (1) Since it is formed about twice as thick as the fixed end of the conventional terminal connection terminal having a diameter of the fixed end, the crack does not occur on the fixed end (1) during the gripping operation of the end (E1) of the conduit (E), Stability of the gripping operation for the fixed end (1) is to be secured. That is, when using a conventional 5.5 mm diameter conduit (E), a metal cylindrical tube having an inner diameter of 5.5 mm is used and the metal cylindrical tube has a thickness of 1 mm, but in the present invention, a metal cylindrical tube having a diameter of 10.5 mm becomes the shaft diameter. The thickness of the fixed end is to be formed close to 2mm.

또한, 직경이 큰 금속관을 압착시키게 되므로 필요한 크기의 체결공(3)이 형성된 압착접속부(2)가 형성되게 되므로 장기간 안전하게 사용할 수 있게 되는 것이다.In addition, since a large diameter metal pipe is pressed, a crimp connection part 2 having a fastening hole 3 of a required size is formed, so that it can be used safely for a long time.

상기 금속관(10)의 직경을 축소시키는 과정은, 도 3에 도시된 바와 같이, 금속관(10)의 외경보다 작은 외경(20a)을 갖는 금형(20)을 금속관(10)의 단부에 강제적으로 압입하여 금속관(10)의 단부의 외경을 축소시키고 점차로 금속관(10)의 단부의 외경을 축소시키는 금형(20)을 반복적으로 사용하므로서, 도 4에 도시된 바와 같이, 금속관(10)의 전선관(E)이 고정되는 고정단부(1)가 형성되게 되는 것이나, 이에 한정되는 것은 아니고, 도시되지는 않았지만 금속관(10)의 외표면에 2개 또는 3개의 롤러를 압착시키면서 금속관(10)의 단부의 직경을 축소시킬 수도 있을 것이다.In the process of reducing the diameter of the metal tube 10, as shown in FIG. 3, a mold 20 having an outer diameter 20a smaller than the outer diameter of the metal tube 10 is forcibly pressed into an end of the metal tube 10. By repeatedly using the mold 20 to reduce the outer diameter of the end of the metal tube 10 and gradually reduce the outer diameter of the end of the metal tube 10, as shown in FIG. 4, the conduit E of the metal tube 10. The fixed end portion 1 is fixed, but is not limited thereto, although not shown, the diameter of the end of the metal tube 10 while pressing two or three rollers on the outer surface of the metal tube 10. Could be reduced.

이와 같이 축경이 되어 금속관(10)의 단부에 전선관(E)이 고정되는 고정단부(1)가 형성되고 축관이 않된 부분을 압착시키면, 도 5에 도시된 바와 같이, 원하는 넓이를 갖는 압착접속부(2)가 형성되게 되는 것이다.As such, when the fixed end portion 1 is formed in which the wire tube E is fixed to the end of the metal tube 10 and the non-axial tube is crimped, the crimp connection portion having the desired width is shown in FIG. 5. 2) will be formed.

이와 같이 압착접속부(2)가 형성된 금속관(10)을 반으로 절단하고 소정크기의 체결공(3)을 천공시키면 원하는 크기의 체결공이 형성된 터미널 접속단자가 형성되게 되는 것이다. As such, when the metal tube 10 having the crimp connection part 2 is cut in half and the fastening hole 3 having a predetermined size is drilled, a terminal connection terminal having a fastening hole of a desired size is formed.

이와 같은 방법에 의하여 제조된 본 발명에 따른 터미널 접속단자(A)는, 도 6에 도시된 바와 같이, 종래의 터미널 접속단자(A')와 비교하여 서로 동일한 크기의 고정단부(1)가 형성되어 있으나 압착접속부(2)는 그 크기가 판이하게 다르게 되어, 동일한 전선관(E)을 고정시키더라도 압착접속부(2)의 크기가 상당히 차이가 나게 되어 종래의 터미널 접속단자(A')의 체결공(3)은 5mm를 넘지 못하나, 본 발명의 터미널 접속단자(A)의 체결공(3)은 종래의 압착접속부(2)의 넓이인 10mm보다도 더 큰 13mm의 체결공(3)의 형성이 가능하게 되는 것이다. Terminal connection terminal A according to the present invention manufactured by such a method, as shown in Figure 6, compared to the conventional terminal connection terminal (A ') is formed of the fixed end portion 1 of the same size as each other Although the crimp connection part 2 is different in size, even if the same conduit E is fixed, the size of the crimp connection part 2 is significantly different, so that the fastening hole of the conventional terminal connection terminal A 'is fixed. (3) is not more than 5mm, but the fastening hole (3) of the terminal connection terminal (A) of the present invention can form a fastening hole (3) of 13mm larger than 10mm, the width of the conventional crimp connection portion (2) Will be done.

본 발명에 따른 터미널 접속단자의 제조방법 및 그 제조방법에 의하여 제조된 터미널 접속단자는 일반 제조공장에서 반복적으로 제조하여 생산할 수 있는 것 이므로 산업상 이용가능성이 있다고 할 것이다.The method of manufacturing a terminal connection terminal according to the present invention and the terminal connection terminal manufactured by the production method will be said to have industrial applicability because it can be produced repeatedly by a general manufacturing plant.
