이하, 본 발명에 따른 온도감응변색 넘버링튜브를 첨부된 도면들을 참조하여 상세히 설명한다.Hereinafter, the thermosensitive color numbering tube according to the present invention will be described in detail with reference to the accompanying drawings.

도 1은 단자에 연결된 케이블전선과 본 발명의 넘버링튜브를 설명하기 위한 도면이고, 도 2는 도 1의 넘버링튜브가 단자와 케이블전선의 연결부분을 감싼 상태를 도시한 도면이다. 1 is a view illustrating a cable wire connected to a terminal and the numbering tube of the present invention, and FIG. 2 is a view illustrating a state in which the numbering tube of FIG. 1 surrounds a connection portion between a terminal and a cable wire.

케이블전선(1)은 사용분야나 용량에 따라 다양한 형태로 제조되고 있는데, 통상적으로 전선(1a)을 피복(1b)이 감싸는 구조로 된다. 이러한 케이블전선의 전 선(1)에는 압착단자(2)가 연결되어 배전반 내부의 수많은 접지단자(미도시)와 결합된다. 또는 케이블전선은 전선은 다른 케이블전선의 전선과 연결된다.The cable wire 1 is manufactured in various forms according to the field of use or capacity, and usually has a structure in which the sheath 1b surrounds the wire 1a. The crimp terminal 2 is connected to the cable 1 of the cable wire and is coupled with a number of ground terminals (not shown) inside the switchboard. Or cable wires are connected to the wires of other cable wires.

넘버링튜브는, 케이블전선의 전선(1a)과 압착단자(2) 사이의 경계부분을 감싸거나, 케이블전선의 전선과 다른 케이블전선의 전선이 연결되는 경계 부분을 감싸거나, 케이블전선을 감싼다. 이러한 넘버링 튜브는 절연성 재질로 되어 있고, 그 표면에는 다른 케이블전선과 구분될 수 있도록 특정 숫자가 인쇄되어 있다. 이와 같이 케이블전선을 구분하기 위한 넘버링튜브를 전기배선이 필요한 분양에서 광범위하게 사용되고 있는 것이다. The numbering tube surrounds the boundary between the wire 1a of the cable wire and the crimp terminal 2, the boundary between the wire of the cable wire and the wire of another cable wire, or surrounds the cable wire. The numbering tube is made of an insulating material, and its surface is printed with a specific number to distinguish it from other cable wires. As such, the numbering tube for separating the cable wire is widely used in the distribution that requires electrical wiring.

도 3은 도 1 및 도 2에 채용되는 넘버링튜브의 제1실시예의 사시도이다. 3 is a perspective view of a first embodiment of a numbering tube employed in FIGS. 1 and 2.

도시된 바와 같이, 본 발명에 따른 온도감응변색 넘버링튜브의 제1실시예는, 전선(1a)과 피복(1b)으로 이루어지는 케이블전선(1)을 감쌈으로써 다른 케이블전선과 구분될 수 있도록 한다. 이때, 넘버링튜브(10)는, 케이블전선(1)에 과전류가 흘러 과열됨으로써 소정의 온도 이상이 되었을 때, 색깔이 변하는 온도변색물질이 함유되어 있다. 이러한 온도변색물질은 예를 들면 시온안료나, 다양한 온도변색 무기안료들이 있으며, 이들 온도변색물질은 넘버링튜브를 제조할때 그 넘버링튜브에 함유한다. As shown, the first embodiment of the thermosensitive color numbering tube according to the present invention allows the cable wire 1 consisting of the wire 1a and the sheath 1b to be wrapped so as to be distinguished from other cable wires. At this time, the numbering tube 10 contains a thermochromic material that changes color when an overcurrent flows over the cable wire 1 to overheat a predetermined temperature. Such thermochromic materials include, for example, Zion pigments, and various thermochromic inorganic pigments, which are contained in the numbering tubes when manufacturing the numbering tubes.

On the other hand, the numbering tube of the present application can be implemented using a heat shrink tube that shrinks when heat is applied as a base material, wherein the tube containing the temperature change material is formed.

도 4는 도 1 및 도 2에 채용되는 넘버링튜브의 제2실시예의 사시도이다.4 is a perspective view of a second embodiment of a numbering tube employed in FIGS. 1 and 2.

도시된 바와 같이, 본 발명에 따른 온도감응변색 넘버링튜브의 제2실시예는, 전선(1a)과 피복(1b)으로 이루어지는 케이블전선(1)을 감쌈으로써 다른 케이블전선 과 구분될 수 있도록 한다. As shown, the second embodiment of the thermosensitive color numbering tube according to the present invention allows the cable wire 1 consisting of the wire 1a and the sheath 1b to be wrapped so as to be distinguished from other cable wires.

이때, 넘버링튜브(10)의 표면 전체에는, 케이블전선(1)에 과전류가 흘러 과열됨으로써 소정의 온도 이상이 되었을 때 색깔이 변하는 온도변색부(11)가 코팅된다. 또, 온도변색부(11)의 상부면에는, 외부 환경에 의하여 그 온도변색부(11)가 손상되는 것을 방지하기 위한 보호층(20)이 형성될 수 있다. 더 나아가, 넘버링튜브(10)를 열수축튜브를 모재로 사용한 후 그 표면에 온도변색부(11) 및 보호층(20)을 형성함으로써 구현될 수 있다. At this time, the entire surface of the numbering tube 10 is coated with a temperature discoloration portion 11 that changes color when an overcurrent flows over the cable wire 1 to overheat a predetermined temperature. In addition, a protective layer 20 may be formed on an upper surface of the temperature change part 11 to prevent the temperature change part 11 from being damaged by an external environment. Furthermore, the numbering tube 10 may be implemented by using the heat-shrinkable tube as a base material, and then forming the temperature discoloration part 11 and the protective layer 20 on the surface thereof.

이러한 구조에 의하여, 케이블전선(1)에 과전류가 흘러 소정 온도이상, 예를 들면 60℃ 이상이 될 경우, 넘버링튜브(10)의 전체 표면에 코팅된 온도변색부(11)가 변색되어 케이블전선에 과부하가 인가되었음을 쉽게 확인할 수 있다. Due to this structure, when overcurrent flows to the cable wire 1 to be above a predetermined temperature, for example, 60 ° C. or more, the temperature discoloration part 11 coated on the entire surface of the numbering tube 10 is discolored, thereby causing the cable wire to be discolored. It is easy to see that overload is applied.

도 5는 도 1 및 도 2에 채용되는 넘버링튜브의 제3실시예의 사시도이다.5 is a perspective view of a third embodiment of the numbering tube employed in FIGS. 1 and 2.

도시된 바와 같이, 본 발명에 따른 온도감응변색 넘버링튜브의 제3실시예는, 전선(1a)과 피복(1b)으로 이루어지는 케이블전선(1)을 감쌈으로써 다른 케이블전선과 구분될 수 있도록 한다. As shown, the third embodiment of the thermosensitive color numbering tube according to the present invention allows the cable wire 1 consisting of the wire 1a and the sheath 1b to be wrapped so as to be distinguished from other cable wires.

이때, 넘버링튜브(10)의 표면에는, 소정의 제1온도에서 변색되는 제1온도변색부(12a)와, 소정의 제2온도에서 변색되는 제2온도변색부(12b)가 코팅되어 있다. 제1온도변색부(12a)와 제2온도변색부(12b)는 넘버링튜브의 표면에 교번되게 형성되거나, 라인처럼 형성될 수 있다. 또, 제1,2온도변색부(12a)(12b)의 상부면에는, 외부 환경에 의하여 그 온도변색부(11)가 손상되는 것을 방지하기 위한 보호층(20)이 형성될 수 있다. 더 나아가, 넘버링튜브(10)를 열수축튜브를 모재로 사용한 후 그 표면에 제1,2온도변색부(12a)(12b) 및 보호층(20)을 형성함으로써 구현될 수 있다. At this time, the surface of the numbering tube 10 is coated with a first temperature discoloration portion 12a discolored at a predetermined first temperature and a second temperature discoloration portion 12b discolored at a predetermined second temperature. The first temperature change part 12a and the second temperature change part 12b may be alternately formed on the surface of the numbering tube, or may be formed like a line. In addition, a protective layer 20 may be formed on the upper surfaces of the first and second temperature discoloration parts 12a and 12b to prevent the temperature discoloration part 11 from being damaged by an external environment. Furthermore, the numbering tube 10 may be implemented by forming the first and second temperature discoloration parts 12a and 12b and the protective layer 20 on the surface after using the heat shrink tube as a base material.

이러한 구조에 의하여, 케이블전선(1)에 과전류가 흘러 소정온도 이상, 예를 들면 60℃ 이상이 될 경우, 제1온도변색부(12a)가 변색되어 케이블전선에 과전류가 흐르고 있음이 표시되고, 결국 전선케이블에 과부하가 인가되었음을 쉽게 확인할 수 있다. 그리고 케이블전선(1)에 더욱 많은 과전류가 흘러 소정온도 이상, 예를 들면 70℃ 이상이 될 경우, 제2온도변색부(12a)가 변색되어 케이블전선(1)에 더욱 많은 과부하가 인가되었음을 쉽게 확인할 수 있다. By such a structure, when overcurrent flows through the cable wire 1 and it becomes more than predetermined temperature, for example, 60 degreeC or more, the 1st temperature change part 12a discolors and it shows that overcurrent flows in a cable wire, As a result, it is easy to confirm that the cable is overloaded. In addition, when more overcurrent flows to the cable wire 1 to be above a predetermined temperature, for example, 70 ° C. or more, the second temperature discoloration unit 12a is discolored, and it is easy that more overload is applied to the cable wire 1. You can check it.

도 6은 도 1 및 도 2에 채용되는 넘버링튜브의 제4실시예의 사시도이다.6 is a perspective view of a fourth embodiment of a numbering tube employed in FIGS. 1 and 2.

도시된 바와 같이, 본 발명에 따른 온도감응변색 넘버링튜브의 제4실시예는, 케이블전선을 감쌈으로써 다른 케이블전선과 구분될 수 있도록 한다. As shown, the fourth embodiment of the thermosensitive color numbering tube according to the present invention allows the cable wire to be wrapped so that it can be distinguished from other cable wires.

이때, 넘버링튜브(10)의 표면에는, 『과부하』 또는 『위험』과 같은 문자 형태의 온도변색부(13)가 형성될 수 있다. 또, 온도변색부(13)의 상부면에는, 외부 환경에 의하여 그 온도변색부(13)가 손상되는 것을 방지하기 위한 보호층(20)이 형성된다. 더 나아가, 넘버링튜브(10)를 열수축튜브를 모재로 사용한 후 그 표면에 온도변색부(13) 및 보호층(20)을 형성함으로써 구현될 수 있다. At this time, on the surface of the numbering tube 10, the temperature discoloration portion 13 of the letter form, such as "overload" or "danger" may be formed. In addition, a protective layer 20 is formed on the upper surface of the temperature change part 13 to prevent the temperature change part 13 from being damaged by an external environment. Furthermore, the numbering tube 10 may be implemented by using the heat shrink tube as a base material, and then forming the temperature discoloration part 13 and the protective layer 20 on the surface thereof.

이러한 구조에 의하여, 케이블전선(1)에 과전류가 흘러 소정온도 이상, 예를 들면 60℃ 이상이 될 경우, 문자 형태의 온도변색부(13)가 변색되어 케이블전선(1)에 과전류가 흐르고 있음이 표시된다. 이에 따라 전성케이블(1)에 과부하가 인가되었음을 쉽게 확인할 수 있다. Due to this structure, when an overcurrent flows through the cable wire 1 to a predetermined temperature or more, for example, 60 ° C. or more, the letter-shaped temperature discoloration unit 13 discolors, and an overcurrent flows in the cable wire 1. Is displayed. Accordingly, it can be easily confirmed that the overload is applied to the malleable cable (1).
