본 고안은 전선퓨우즈의 고정장치에 관한 것으로, 특히 주상변압기의 2차측에서 과전압이 유기되어 각 수용가로 직접 전달되는 것을 방지하기 위한 전선퓨우즈를 간단하고 안정성있게 설치할 수 있도록 한 전선퓨우즈의 고정 장치에 관한 것이다.The present invention relates to a device for fixing the wire fuse, and in particular, it is possible to install a wire fuse for simple and stable installation of wire fuse to prevent the overvoltage from being induced in the secondary side of the column transformer. It relates to a fixing device.

일반적으로 각 가정이나 사무실등의 전기 사용장소로 적절한 전기를 공급하기 위하여 330V의 고압이 케이블을 통해 근접지역까지 전달되도록 하고, 전주에 설치된 주상 변압기에 의해 220V로 전압강하된 후 공급되도록 하였음은 이미 잘 알려진 사실이다.In general, in order to supply proper electricity to each home or office, the high voltage of 330V is transmitted to the adjacent area through the cable, and it is supplied after the voltage drops to 220V by the pole transformer installed in the pole. This is a well known fact.

그리고 각각의 주상 변압기의 2차측 코일에 연결되어 220V를 각 수용가로 공급하는 전원선에는 전선퓨우즈를 설치하여 220V보다 높은 과전압이 전달되지 않도록 하였다.In addition, a wire fuse was installed on the power line connected to the secondary coil of each column transformer to supply 220V to each customer so that overvoltage higher than 220V was not transmitted.

종래에는 주상전압기의 2차측 코일에 연결된 전선과, 각 수용가로 연결되는 전선의 사이에 전선 접속단자를 개재하여 납의 양쪽에 두 저항선을 접속한 가용체를 조립하고, 상기 가용체의 양측에 결합체를 조립하면서 외부로 외통을 결합하도록 하였었다.Conventionally, a soluble body in which two resistance wires are connected to both sides of a lead is assembled between a wire connected to a secondary coil of a pole voltage transformer and a wire connected to each consumer via wire connection terminals, and a coupling body is formed on both sides of the soluble body. While assembling the outer cylinder was to be coupled to the outside.

그리고 가용체의 양측에 위치하는 전선접속단자를 외통에 고정시키기 위하여 제6도에 도시한 것과 같이 전선접속단자(21)의 끝단이 외통(22)의 고정홀(22a)에 끼워지도록 한후 초음파 융착의 방법으로 접착시키거나, 제7도에 도시한 것과 같이 전선접속단자(23)의 끝단이 외통(24)의 고정홀(24a)에 끼워지도록 한후 전선접속단자(23) 및 외통(24)의 핀공(23a)(24b)을 통하여 핀(25)을 삽입하여 고정시켰었다.In order to fix the wire connecting terminals located on both sides of the soluble body to the outer cylinder, the end of the wire connecting terminal 21 is fitted into the fixing hole 22a of the outer cylinder 22, as shown in FIG. Or the end of the wire connecting terminal 23 is inserted into the fixing hole 24a of the outer cylinder 24 as shown in FIG. 7 and then the wire connecting terminal 23 and the outer cylinder 24 The pin 25 was inserted and fixed through the pin holes 23a and 24b.

그러나 상기와 같은 종래의 전선퓨우즈의 고정장치에 의하여서는, 변압기에서 수용가로 전원선에 전선퓨우즈가 설치되는 상태이므로 전선퓨우즈의 고정작업이 공중에서 행하여지게 되는데, 설치 공정이 복잡하고 그에 따른 작업시간도 길어져 사용에 많은 불편이 있었다.However, in the conventional wire fuse fixing device as described above, since the wire fuse is installed in the power line from the transformer to the customer, the wire fuse fixing is performed in the air, and the installation process is complicated and Work time was also long, so there was a lot of inconvenience.

그리고 과전압에 의해 녹은 가용체의 납성분이 외통으로 튕겨지면서 손상을 입게되는 등의 문제점이 있었다.In addition, there was a problem such that the lead component of the soluble substance melted by the overvoltage was damaged by being thrown into the outer cylinder.

이에따라 본 고안은 전선퓨우즈를 간단하고 안정성 있게 설치하도록 한 전선퓨우즈의 고정장치를 제공하는 것을 그 목적으로 한다.Accordingly, an object of the present invention is to provide a wire fuse fixing device for simple and stable installation of wire fuse.

이와같은 목적을 달성하기 위한 본 고안은 주상변압기의 2차측 코일에 연결된 전선과 각 수용가로 연결되는 전선은 각각 전선 접속단자에 삽입되도록 하고, 상기의 전선 접속단자의 내측에는 사이에 납을 통해 두 저항선이 접속된 가용체의 양끝을 삽입 고정하며, 상기 수용가측 전선 접속단자가 삽입된채 사출형성되는 외부결합체에는 수용가측 단자커버를 결합하면서 소호통이 끼워지도록 하는 한편, 상기의 소호통과 외부결합체에 내측의 소호통지지캡 및 외측의 전주측 단자커버와 함께 결합되는 외통캡은 전주측 전선 접속단자가 삽입된채 사출성형되도록 함으로써 간단하면서 안정성 있는 설치가 가능하도록 한 것이다.The present invention for achieving the above object is to ensure that the wire connected to the secondary coil of the column transformer and the wire connected to each customer is inserted into the wire connection terminal, respectively, through the lead between the inside of the wire connection terminal; Both ends of the soluble body to which the resistance wire is connected are inserted and fixed, and the sub-cylinder can be inserted into the external coupling body which is formed by injection while the customer-side wire connection terminal is inserted, while the sub-cylinder is fitted with the sub-terminal cover.
