Abstract
본 고안은 접지용 접지봉과 접지단자에 관한 것으로, 종래에는 동관의 확장부로 접지단자를 압입시키는 관계로, 확장부의 연신율로 인하여 그 두께가 얇아지는 문제점을 발생하면서 확장부가 찌그러지거나 또는 크랙의 발생 위험이 있고, 이로인하여 접지저항이 크게 저하되는 문제점이 초래되었다. 즉, 동관의 인발 작업시 인발작업이 가능한 소재경도를 확보를 위하여 동관의 재질을 'KSD 5301 C1100 T-1/2H(두께 1.5t)'의 소재를 사용하고 있는 관계로, 동관의 상단에 형성되는 확장부로 접지단자를 압입시 그 두께가 얇아지는 문제점을 해결할수 없었으며, 이로인하여 ONE PIECE STREIGHT 인발 작업은 제품경도가 약화되어 찌그러짐과 크랙발생을kr막을수 없는 폐단이 따랐다.The present invention relates to a grounding rod and a ground terminal for grounding, and in the related art, the ground terminal is press-fitted to the expansion part of the copper pipe, and the thickness of the extension part is thinned due to the elongation of the expansion part, and the risk of occurrence of crushing or cracking of the extension part is caused. This has caused a problem that the ground resistance is greatly reduced. In other words, in order to secure the material hardness that can be pulled out when the copper pipe is drawn, the material of the copper pipe is formed at the top of the copper pipe as it uses the material of 'KSD 5301 C1100 T-1 / 2H (1.5t thick)'. It was not possible to solve the problem of thinning the thickness of the ground terminal by press-fitting the expansion terminal. As a result, the ONE PIECE STREIGHT drawing work was weakened due to the weakening of the product hardness, which prevented crushing and cracking.
이에 본 고안은, 인발 작업이 이루어진 동관에다 'KSD 5301 C 1100 T-3/4H(두께 1.5t)'의 소재인 분리형의 단자접합용 파이프를 덮어씌워 압착시키므로서, 동관 원소재의 두께를 원상 그대로 일정하게 유지하면서 경도 및 인장강도를 증대시키고, 더불어 찌그러짐이나 크랙현상을 방지하면서 접지전도율을 향상시켜 제품의 신뢰성을 증진시킨 접지용 접지봉과 접지단자를 제공한다.Therefore, the present invention covers the crimped copper tube raw material by covering the crimped terminal joining pipe of KSD 5301 C 1100 T-3 / 4H (thickness 1.5t) and the crimped copper tube. It provides a grounding rod and a grounding terminal for improving the reliability of the product by improving the conductivity while increasing the hardness and tensile strength while preventing it from being crushed or cracked.

When pressing the ground terminal 5 into the expansion part 3 formed on the upper part of the copper pipe 2, the thickness could not be solved. Therefore, ONE PIECE STREIGHT drawing work is weakened due to weakened product hardness. There was a closed end where ground conductivity could not be achieved.
따라서, 본 고안은 상기와 같은 종래의 문제점을 해결하기 위해 인발 작업이 이루어진 동관에다 분리형인 단자접합용 파이프를 덮어씌워 압착시키므로서, 동관 원소재의 두께를 원상 그대로 일정하게 유지하면서 경도 및 인장강도를 증대시키고, 더불어 찌그러짐이나 크랙현상을 방지하면서 접지전도율을 향상시켜 제품의 신뢰성을 증진시킨고자 하는데 그 목적이 있는 것이다.Therefore, the present invention covers and crimps the copper tube, which has been pulled out, to cover the conventional terminal joining pipe in order to solve the conventional problems as described above, while maintaining the thickness of the copper tube raw material as it is, while maintaining hardness and tensile strength. The purpose is to increase the reliability of the product by increasing the grounding conductivity while preventing crushing or cracking.

그러면, 상기 단자접합용 파이프(10)의 중심부(10b)가 동관(2)의 상단부를 압착시키므로서, 상기 단자접합용 파이프(10)와 동관(2)의 고정은 견고하게 이루어진다.Then, the center portion 10b of the terminal joining pipe 10 compresses the upper end of the copper pipe 2, so that the terminal joining pipe 10 and the copper pipe 2 are firmly fixed.
이후, 상기 동관(2)으로의 압착이 이루어진 단자접합용 파이프(10)의 상단부(10c)에 접지선(6)이 결합되어 있는 접지단자(5)를 압입하면, 접지용 접지봉(1)과 접지단자(5)의 결합이 완료되는 것이다.Subsequently, when the ground terminal 5 having the ground wire 6 is coupled to the upper end portion 10c of the terminal joining pipe 10 that has been crimped to the copper pipe 2 is pressed in, the grounding ground rod 1 for grounding and grounding The coupling of the terminals 5 is completed.
즉, 본 고안은 상기에서와 같이 접지단자(5)의 결합을 위해 접지봉(1)의 동관(2)에 분리형의 단자접합용 파이프(10)를 프레스로 압착시키면, 접지단자(5)를 압입시켜도 동관(2) 원소재의 두께를 원상 그대로 일정하게 유지하면서 그 경도 및 인장강도를 높일수 있고, 더불어 동관(2)의 찌그러짐이나 크랙현상을 방지하면서 접지전도율을 향상시킬수 있게 되는 것이다.In other words, the present invention is to press the separable terminal joining pipe 10 to the copper tube (2) of the grounding rod (1) by the press for the coupling of the ground terminal (5) as described above, press-in the ground terminal (5) Even if it is made, the hardness and tensile strength of the copper tube 2 can be increased while maintaining the thickness of the raw material of the copper tube 2 as it is, and the grounding conductivity can be improved while preventing crushing or cracking of the copper tube 2.
이상에서 설명한 바와같이 본 고안은 인발 작업이 이루어진 동관에다 로렛 전조 가공을 한 후 이에 분리형인 단자접합용 파이프를 덮어씌워 압착시키므로서, 동관 원소재의 두께를 원상 그대로 일정하게 유지하면서 경도 및 인장강도를 증대시키고, 더불어 찌그러짐이나 크랙현상을 방지하면서 접지전도율을 향상시켜 제품의 신뢰성을 증진시키는 효과를 제공한다.As described above, the present invention covers the crimped terminal joint pipe after pressing LETEL on the copper tube where the drawing work is done, and compresses the same, thereby maintaining the thickness of the copper tube raw material as it is and maintaining its hardness and tensile strength. In addition, it provides the effect of improving the reliability of the product by improving the grounding conductivity while preventing crushing or cracking.
