본 발명은 밴드형 접지장치에 관한 것으로서, 보다 상세하게는, 접지선을 원통형 접지체에 쉽게 접지시킬 수 있는 밴드형 접지장치에 관한 것이다.The present invention relates to a band-type grounding device, and more particularly, to a band-type grounding device that can easily ground the ground wire to the cylindrical grounding body.

접지란 전자기기, 통신장비, 계측장비 등 전기설비 시스템과 피뢰설비의 접지선을 대지, 즉 지구에 전기적으로 접속시켜 주는 것을 말한다. 접지는 장비와 지구를 전기적으로 접속시켜 장비에 작용하는 과부하나 낙뢰 등에 의한 서지전압을 대지로 흘려보내 과부하 및 서지전압으로부터 장비의 손상을 방지하고 첨단 전자장비의 오동작을 방지하여 안정적인 동작을 하도록 해준다. Grounding refers to electrically connecting the ground wires of the electrical installation system such as electronic equipment, communication equipment, and measurement equipment and the lightning protection equipment to the earth, that is, the earth. Grounding electrically connects the earth to the equipment, and sends a surge voltage caused by an overload or lightning strike to the ground to prevent damage to the equipment from overload and surge voltage and to prevent malfunction of advanced electronic equipment. .

종래의 접지방식은 대지에 대한 저항에 따라 한 개의 접지전극을 지중에 매설하거나, 복수의 접지전극을 매설하여 장비와 전기적으로 연결하는 것이다. In the conventional grounding method, one ground electrode is buried in the ground or a plurality of ground electrodes are electrically connected to the equipment according to resistance to the ground.

여기서, 접지체(접지전극)와 접지선을 연결하기 위한 접지장치가 마련되는데, 이 때 접지장치는 접지선이 인입되는 부분이 원형으로 이루어져 있고 접지체에 접속되는 부분이 평면으로 구성되어 접지체에 나사 방식으로 결합되는 구조로 이루어져 있다. Here, a grounding device for connecting a grounding body (grounding electrode) and a grounding wire is provided. At this time, the grounding device has a circular portion where the grounding wire is drawn in and a portion connected to the grounding body has a flat surface and is screwed to the grounding body. It consists of a structure that is combined in a manner.

따라서, 종래의 접지장치의 경우에는, 접지체에 접속되는 부분이 평면으로 구성되어 있으므로 원통형 접지체에 접지선을 연결하기 위한 작업이 상당히 불편할 뿐만 아니라, 별도의 타이(tie)를 이용하여 접지체에 접지장치를 묶는다고 하여도 접지선과 접지체 간의 이격 등에 의한 접촉저항이 커서 전자파에 취약한 디지털 장비 등의 기준 전위 확보에 어려움이 있었다. Therefore, in the case of the conventional grounding device, since the part connected to the grounding body is formed in a plane, the work for connecting the grounding wire to the cylindrical grounding body is quite inconvenient, and a separate tie is used for the grounding body. Even when the grounding device is bundled, it is difficult to secure the reference potential of digital equipment, which is vulnerable to electromagnetic waves due to the large contact resistance due to the separation between the ground wire and the grounding body.

따라서, 본 발명의 목적은 접지선을 원통형 접지체에 쉽게 접지시킬 수 있어 작업성이 향상될 뿐만 아니라, 접지선과 접지체 간의 접촉저항을 최소화시켜 접지 효율을 향상시킬 수 있는 밴드형 접지장치를 제공하는 것이다.

이하에서는 첨부도면을 참조하여 본 발명에 대해 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 밴드형 접지장치가 옥내소화전의 스프링쿨러 배관에 설치된 상태를 도시한 사시도이고, 도 2a는 도 1의 A부분의 평면도이고, 도 2b는 도 1의 A부분의 측면도이고, 도 3은 본 발명에 따른 밴드형 접지장치를 위에서 본 상태를 도시한 사시도이고, 도 4는 본 발명에 따른 밴드형 접지장치를 아래에서 본 상태를 도시한 사시도이다. 이들 도면에 도시된 바와 같이, 본 발명에 따른 밴드형 접지장치(1)는 디지털 장비(3)를 접지선(15)을 이용하여 원통형 접지체(5)에 접지시킬 때 이용되는 연결장치로서, 수용부(미도시)가 함몰 형성되어 있고 양측에 밴드 관통부(11a, 11b)가 형성된 케이싱(10)과, 원통형 접지체(5)의 둘레에 고정되도 록 케이싱(10)에 결합된 밴드(45)와, 원통형 접지체(5)와 케이싱(10) 사이에 마련된 고무 밀착부(20)와, 고무 밀착부(20)의 내부(20a)에 마련되어 접지선(15) 및 원통형 접지체(5)와 연결되어 원통형 접지체(5)로 전류를 방류시키는 도전부재(40, 도 5a참조)를 포함하여 이루어진다. 1 is a perspective view showing a state in which the band-type grounding apparatus according to the present invention is installed in the sprinkler pipe before the indoor fire extinguishing, FIG. 2A is a plan view of the portion A of FIG. 1, and FIG. 2B is a side view of the portion A of FIG. 3 is a perspective view showing the band-type grounding apparatus according to the present invention as viewed from above, and FIG. 4 is a perspective view showing the band-type grounding apparatus according to the present invention viewed from below. As shown in these figures, the band-type grounding device 1 according to the present invention is a connecting device used when the digital equipment 3 is grounded to the cylindrical grounding body 5 by using the grounding wire 15. A casing 10 in which a portion (not shown) is recessed and band through portions 11a and 11b are formed on both sides, and a band 45 coupled to the casing 10 so as to be fixed around the cylindrical ground body 5. ), A rubber contact portion 20 provided between the cylindrical grounding body 5 and the casing 10, and a ground wire 15 and a cylindrical grounding body 5 provided in the interior 20a of the rubber contacting portion 20. And a conductive member 40 (see FIG. 5A) for discharging current to the cylindrical ground body 5.

케이싱(10)은 수용부가 함몰 형성된 구조이며, 플라스틱으로 사출 제작된다. 이 때, 케이싱(10)의 상부면에는 투명한 재질로 제작되어 로고 등이 삽입될 수 있는 디스플레이부(13)가 결합되어 있다. 그리고, 케이싱(10)의 상부면 양측에는 대향하는 위치에 각각 밴드 관통부(11a, 11b)가 형성되어 있다. 또한, 케이싱(10)의 일측면에는 크롬도금 접속침(30)이 삽입되기 위한 접속침 삽입부(12)가 마련되어 있다. 여기서, 케이싱(10)의 형상과 밴드 관통부(11a, 11b)의 위치는 이에 한정되지 않고 다양하게 변화될 수도 있음은 물론이다. The casing 10 has a structure in which the receiving portion is recessed and is manufactured by injection molding of plastic. At this time, the upper surface of the casing 10 is made of a transparent material is coupled to the display unit 13 can be inserted into the logo. Band through portions 11a and 11b are formed at opposing positions on both sides of the upper surface of the casing 10. In addition, one side of the casing 10 is provided with a connecting needle inserting portion 12 for inserting the chromium plating connecting needle 30. Here, the shape of the casing 10 and the position of the band penetrating portions 11a and 11b are not limited thereto, but may be variously changed.

크롬도금 접속침(30)은, 도 5a에 도시된 바와 같이, 접속침 삽입부(12)에 삽입되어 도전부재(40)에 연결되는 침부(31)와, 침부(31)와 일체 형성되어 접지선(15)이 결합되는 접지선 결합단(33)으로 구성되어 있다. 이에, 디지털 장비(3)와 연결된 접지선(15)에 흐르는 전류는 크롬도금 접속침(30)을 거쳐 도전부재(40)로 통함으로써, 원통형 접지체(5)에 접지될 수 있다. 여기서, 크롬도금 접속침(30)은 동보다 도전률이 좋은 크롬으로 도금되어 있어 접지 효율이 훨씬 좋은 효과가 있다. As shown in FIG. 5A, the chromium plating connecting needle 30 is integrally formed with the needle 31 inserted into the needle insertion part 12 and connected to the conductive member 40, and the needle 31. It consists of a ground wire coupling end 33 to which 15 is coupled. Accordingly, the current flowing through the ground wire 15 connected to the digital device 3 may be grounded to the cylindrical grounding body 5 by passing through the chromium plating connecting needle 30 to the conductive member 40. Here, the chromium plating connecting needle 30 is plated with chromium having a higher conductivity than copper, so that the grounding efficiency is much better.

이 때, 크롬도금 접속침(30)의 둘레에는 침부(31)가 접속침 삽입부(12)에 삽입된 후 이탈되는 것을 방지하는 걸림홈(32)이 형성되어 있다. 즉, 작업자가 크롬 도금 접속침(30)의 침부(31)를 접속침 삽입부(12)를 향해 밀어 넣으면, 이 때 걸림홈(32)에는 접속침 삽입부(12)의 내측면에 돌출 형성된 걸림 돌기(14)가 걸림으로써, 크롬도금 접속침(30)이 접속침 삽입부(12)로부터 빠지지 않게 된다. 한편, 작업자는 걸림 돌기(14)가 걸림홈(32)에 끼워짐으로써, 크롬도금 접속침(30)이 삽입된 상태를 쉽게 인지할 수 있다. 여기서, 케이싱(10)이 약간의 탄성을 가진 플라스틱으로 이루어졌기 때문에, 침부(31)가 접속침 삽입부(12)로 들어갈 때 걸림 돌기(14)가 약간 변형되어 접속침 삽입부(12)에 삽입될 수 있는 것이다. At this time, the locking groove 32 is formed around the chrome plated connecting needle 30 to prevent the needle 31 from being separated after being inserted into the connecting needle inserting portion 12. That is, when the operator pushes the needle 31 of the chrome-plated connecting needle 30 toward the connecting needle inserting portion 12, the locking groove 32 protrudes from the inner surface of the connecting needle inserting portion 12 at this time. When the locking projection 14 is locked, the chrome-plated connecting needle 30 does not come out of the connecting needle inserting portion 12. On the other hand, the operator can easily recognize the state that the chrome plating connecting needle 30 is inserted by the locking projection 14 is fitted into the locking groove (32). Here, since the casing 10 is made of a plastic having a slight elasticity, when the needle portion 31 enters the needle insertion portion 12, the catching protrusion 14 is slightly deformed to the needle insertion portion 12. It can be inserted.

한편, 접지선 결합단(33)의 외표면에는 압착 표시부(34)가 마련되어 있는데, 압착 표시부(34)는 작업자가 접지선 결합단(33)을 가압할 때 그 가압 위치를 알려주기 위한 것이다. 즉, 작업자는 접지선(15)의 일단을 접지선 결합단(33) 내부에 삽입한 후 압착 표시부(34) 부근의 접지선 결합단(33)을 눌러 접지선(15)이 접지선 결합단(33)으로부터 빠지지 않도록 할 수 있다. On the other hand, the outer surface of the ground wire coupling end 33 is provided with a crimp display portion 34, the crimp display portion 34 is to inform the pressing position when the operator presses the ground wire coupling end (33). That is, the operator inserts one end of the ground wire 15 into the ground wire coupling end 33 and presses the ground wire coupling end 33 near the crimp display part 34 so that the ground wire 15 is pulled out of the ground wire coupling end 33. You can do that.

밴드(45)는 케이싱(10)을 원통형 접지체(5)에 고정시키기 위한 결합 수단으로서, 일단이 한쪽의 밴드 관통부(11a)를 지나 케이싱(10)의 내부를 거쳐 다른 쪽의 밴드 관통부(11b)로 빠져나오도록 조립된다. 이 때, 밴드(45)의 양단에는 밴드(45)를 고정시키기 위한 버클이 마련될 수도 있고, 버클과 같은 별도의 버클이 마련되지 않고 단순히 밴드(45)의 양단을 묶어서 케이싱(10)을 원통형 접지체(5)에 고정시킬 수도 있음은 물론이다. The band 45 is a coupling means for fixing the casing 10 to the cylindrical grounding body 5, one end of which passes through one band through portion 11a and passes through the inside of the casing 10 to the other band through portion. It is assembled to come out to 11b. At this time, both ends of the band 45 may be provided with a buckle for fixing the band 45, without a separate buckle, such as a buckle is simply provided by tying both ends of the band 45 to the cylindrical casing 10 Of course, it can also be fixed to the grounding body (5).

고무 밀착부(20)는 케이싱(10)의 수용부에 장착되는데, 이는 케이싱(10)이 원통형 접지체(5)와 밀착되도록 하는 기능을 수행한다. 따라서, 케이싱(10)과 원통 형 접지체(5)의 이격 공간이 적어 접촉저항이 최소화된 상태에서 접지될 수 있으므로 접지효율이 극대화될 수 있다. The rubber contact portion 20 is mounted to the receiving portion of the casing 10, which serves to bring the casing 10 into close contact with the cylindrical ground body 5. Therefore, since the space between the casing 10 and the cylindrical grounding body 5 is small, the contact resistance can be grounded in a minimized state, and thus the grounding efficiency can be maximized.

이러한 고무 밀착부(20)는 내부(20a)가 빈 형상의 몸체(21)와, 몸체(21)의 상부면에 몸체(21)와 일체 형성되어 케이싱(10)이 내측 상부면에 끼워지는 걸림편(22)과, 몸체(21)의 하단으로부터 외측으로 연장되어 원통형 접지체(5)에 밀착되는 밀착편(23)으로 구성된다. 또한, 고무 밀착부(20)는 접속침 삽입부(12)에 삽입되는 접속단(24)이 몸체(21)에 일체로 형성되어 있다. The rubber contact part 20 has an interior 20a formed with an empty body 21 and a body 21 integrally formed on the upper surface of the body 21 so that the casing 10 is fitted onto the inner upper surface. It consists of a piece 22 and an adhesion piece 23 extending outward from the lower end of the body 21 to be in close contact with the cylindrical ground body 5. In addition, as for the rubber close part 20, the connection end 24 inserted into the connection needle insertion part 12 is integrally formed in the body 21. As shown in FIG.

걸림편(22)은 몸체(21)를 케이싱(10)에 결합시키기 위한 것으로서, 케이싱(10)의 내측 상부면에는 걸림편(22)이 끼워질 수 있도록 동일한 형상의 홈이 형성되어 있음은 물론이다. The locking piece 22 is for coupling the body 21 to the casing 10, and grooves having the same shape are formed on the inner upper surface of the casing 10 so that the locking piece 22 can be fitted thereto. to be.

접속단(24)에는 크롬도금 접속침(30)의 침부(31)가 도전부재(40)에 삽입될 수 있도록 "+"자 형상의 절개선(24a)이 형성되어 있는 것이 좋다. 이에, 크롬도금 접속침(30)의 침부(31)는, 도 5b에 도시된 바와 같이, 접속침 삽입부(12)를 통과한 후 절개선(24a)을 따라 절개된 접속단(24)의 내부로 삽입되어 도전부재(40)와 연결될 수 있다. The connecting end 24 is preferably formed with a cut line 24a having a “+” shape so that the needle 31 of the chromium plated connecting needle 30 can be inserted into the conductive member 40. Accordingly, the needle portion 31 of the chromium plated connecting needle 30 passes through the connecting needle inserting portion 12 and then cuts along the cut line 24a as shown in FIG. 5B. It may be inserted into the conductive member 40.

도전부재(40)는 고무 밀착부(20)의 내부(20a)에 마련되는데, 본 실시예에서의 도전부재(40)로는 겔(gel) 타입의 도전성 실리콘이 고무 밀착부(20)의 내부(20a)에 주입된다. 그러나, 도전부재(40)는 이에 한정되지 않고, 전도액이 흡수된 스폰지가 고무 밀착부(20)의 내부(20a)의 형상에 맞게 제작되어 삽입되거나, 점토형 도전체로 이루어질 수도 있음은 물론이다. 여기서, 점토형 도전체는 적토, 벤 토나이트, 흑연 중 어느 하나이며, 이에 한정되지 않고 도전성을 가진다면 공지된 다른 물질도 가능할 것이다. Conductive member 40 is provided in the interior (20a) of the rubber contact portion 20, the conductive member 40 in the present embodiment is a gel (gel) type of conductive silicon inside the rubber contact portion 20 ( Injected into 20a).
