Instead of connecting, a connection medium is used. When such a connection medium is used, the conductor of the power cable is inserted and fixed to one side, and the connecting member to supply and connect power to the other side is configured to be energized with each other.

그런데, 위와 같이 접속용 매개체의 내부에는 전력 케이블의 도체를 고정하기 위한 많은 부품들이 내장되어 있어 구조적으로 매우 복잡하여 접속용 매개체의 제작이 어렵고, 전력 케이블의 고정작업도 수월하지 못하다. 특히 필요에 따라 교체작업을 하고자 할 경우, 전력 케이블 및 접속부재와의 분리가 용이하지 못해 교체에 대한 어려움과 상당한 작업시간이 소요되는 문제도 있다.

다음에서는 본 발명의 실시 예를 도시한 도면을 참조하여 본 발명의 구체적인 구성에 대하여 설명한다. Hereinafter, with reference to the drawings showing an embodiment of the present invention will be described a specific configuration of the present invention.

첨부된 예시도면 도 1은 일반적인 전력 케이블의 도체에 본 발명의 압착금구가 압착.고정되는 모습을 보여주는 도면이고, 도 2는 도 1의 압착금구에 본 발명의 결합구가 결합되어 접속용 접속부재와 체결되는 모습을 보여주는 도면이다. 1 is a view showing a state in which the crimping fixture of the present invention is crimped and secured to a conductor of a general power cable, and FIG. 2 is a connection member for connecting the coupling tool of the present invention to the crimping fixture of FIG. 1. Is a view showing a state that is fastened with.

첨부된 예시도면을 참조하여 본 발명의 구성 요소를 개략적으로 살펴보면, 먼저 전력케이블(10)의 도체(12)에 압착.고정되는 압착금구(14)와, 상기 압착금구(14)가 결합되는 상태에서 접속부재(16)에 결합되는 결합구(18)로 구성된다.Referring to the components of the present invention with reference to the accompanying drawings schematically, first, the crimping fixture 14, which is crimped and fixed to the conductor 12 of the power cable 10, the state in which the crimping fixture 14 is coupled Consists of a coupler 18 is coupled to the connecting member 16 in.

구체적으로, 앞서 언급된 상기 압축금구(14)는, 일 측면에 전력 케이블(10)의 도체(12)가 일부 삽입되어 압착.고정이 이루어질 수 있도록 압착부(20)가 형성되어 있다.Specifically, the compression bracket 14 mentioned above is formed with a crimping portion 20 so that the conductor 12 of the power cable 10 is partially inserted into one side thereof so as to be crimped and fixed.

또한, 상기 압착부(20)의 일 측 단부에는 압착금구(14)가 후술하는 결합구(18)에 삽입.고정시, 결합을 강화하고 접촉면적을 넓혀 통전 저항을 작게 형성하기 위한 압지날개(22)가 원주를 따라 서로 간격을 갖고 하나 이상 형성된다. 이때 상기 압지날개(22)는 압지기능이 발휘될 수 있도록 소정의 각도( θ)만큼 벌어지는 구조로 이루어져 있다.In addition, at one end of the crimping portion 20, the crimping tool 14 is inserted into the coupling tool 18, which will be described later. At the time of fixation, the clamping blade for strengthening the coupling and widening the contact area to form a small current resistance ( 22 are formed at least one spaced apart from each other along the circumference. At this time, the blotting blade 22 has a structure that is opened by a predetermined angle (θ) so that the blotting function can be exhibited.

그리고, 상기 압착금구(14)와 결합되는 결합구(18)를 살펴보면, 내부에 형성되는 관통공(24)을 통해 중공의 구조로 구성된다. 이러한 결합구(18)의 일측 외면 부분에는 접속용 접속부재(16)와 체결될 수 있도록 나선부(26)가 형성되어 있다.And, looking at the coupling sphere 18 is coupled to the crimping tool 14, it is made of a hollow structure through the through hole 24 formed therein. On one side of the outer surface portion of the coupler 18, a spiral portion 26 is formed to be fastened to the connection member 16 for connection.

위와 같이 구성되는 압착금구(14)와 결합구(18)를 이용하여 전력 케이블(10)과 접속부재(16)를 전기적으로 연결시 킬 경우, 우선 도 1에 도시된 바와 같이 전력 케이블(10)의 일단을 통해 결합구(18)를 미리 결합시킨다.When the power cable 10 and the connecting member 16 are electrically connected by using the crimping tool 14 and the coupling tool 18 configured as described above, the power cable 10 as shown in FIG. Couple the coupling sphere 18 in advance through one end.

그리고, 상기 전력 케이블(10)의 도체(12)를 압착금구(14)의 압착부(20) 내부로 삽입시킨 후, 압착부(20)를 압착시켜 도체(12)가 이탈되지 않도록 고정시킨다.Then, the conductor 12 of the power cable 10 is inserted into the crimping portion 20 of the crimping tool 14, and then the crimping portion 20 is crimped to fix the conductors 12.

위와 같은 상태에서 도 2에 도시된 바와 같이 사전에 결합된 결합구(18)를 화살표 방향으로 전진시키게 되는데, 이때 압착금구(14)의 압지날개(22)가 결합구(18)의 내면을 압지하는 상태로 삽입시킨다. In the above state, as shown in FIG. 2, the coupler 18 coupled in advance is advanced in the direction of the arrow. At this time, the presser blade 22 of the crimping tool 14 presses the inner surface of the coupler 18. Insert it in the

이때, 상기 압착금구(14)의 일측에 형성되는 걸림돌기(30)는 관통공(24)의 일정 구간을 확관하여 형성되어진 단턱부(32)에 걸림되는 상태가 되므로, 압착금구(14)로부터 결합구(18)가 빠져나오지 않게 된다. 이와 같이 결합된 상태에서 결합구(18)의 나선부(26)와 접속부재(16)간에 서로 체결하여 전기적인 접속이 완료된다.At this time, since the locking projection 30 formed on one side of the pressing bracket 14 is in a state of being caught by the stepped portion 32 formed by expanding a predetermined section of the through hole 24, from the pressing bracket 14 The coupler 18 does not come out. The electrical connection is completed by fastening each other between the spiral portion 26 and the connecting member 16 of the coupler 18 in the coupled state.

그러나, 상기 결합구(18)가 접속부재(16)에 결합되도록 하고자 반드시 나선부(26)로 한정될 필요는 없다. 이는 본 발명에 대한 설명과 목적에 대한 이해를 돕고자 일 예에 불과할 뿐이며, 서로 결합과 분리가 용이하다면 어떠한 구조 및 균등한 수단의 채택과 변경도 가능할 것이다.However, the coupler 18 is not necessarily limited to the spiral portion 26 in order to be coupled to the connecting member 16. This is only an example to help understand the description and the purpose of the present invention, and if it is easy to combine and separate from each other, any structure and equivalent means may be adopted and changed.

한편, 상기 전력 케이블(10), 결합금구(14), 결합구(18), 접속부재(16)의 파손이나 손상으로 인하여 교체가 요구되는 경우, 종래에는 구조적으로 복잡하여 분 리 및 분해가 용이하지 못하였으나, 본 발명에서는 결합구(18)의 체결방식과 압착금구(14)의 압지방식으로 인하여, 분리 및 분해가 용이함으로 종래에 제시되었던 모든 문제점을 해소할 수 있게 된다.On the other hand, when replacement is required due to damage or damage of the power cable 10, the coupling bracket 14, the coupling tool 18, the connection member 16, the conventional structure is complicated and easy to separate and disassemble However, in the present invention, due to the fastening method of the coupler 18 and the pressing method of the crimping tool 14, it is possible to solve all the problems presented in the prior art by the easy separation and disassembly.

또한, 본 발명을 사용하게 되면, 상기 압착금구(14)의 압착날개(22)는 앞서 설명하였듯이 압지기능을 발휘하지만, 아울러 전기적 접촉 면적을 넓게 형성하여 통전에 따른 전기적 저항을 작게 하는 기능도 발휘함으로써, 안정적인 전력 공급 및 연결이 이루어질 수 있게 된다.In addition, when the present invention is used, the crimping wing 22 of the crimping tool 14 exhibits a paper-pressing function as described above, but also exhibits a function of reducing the electrical resistance due to energization by forming a wide electrical contact area. Thus, stable power supply and connection can be made.

Various modifications and variations will be possible within the scope of the claims set forth below.

또한, 본 발명에 기재된 설명과 도면에 구성은, 본 발명의 가장 바람직한 일 실시 예에 불과할 뿐, 이것이 본 발명의 기술적 사상을 모두 대변하는 것을 의미하는 것이 아니므로, 이들을 대체할 수 있는 다양한 균등물과 변형구조의 예가 더 있을 수 있다. In addition, the configuration in the description and drawings described in the present invention is only one of the most preferred embodiment of the present invention, and this does not mean that all represent the technical idea of the present invention, various equivalents that may be substituted for them There may be further examples of the deformation structure.

이상에서 살펴본 바와 같이, 전력 케이블의 도체가 압착금구에 압착.고정되는 구조와, 압착금구가 결합구의 내면에 삽입되어 압지.고정되는 구조에 의해 간단한 구조를 이루어 조립작업 및 분리가 용하여 작업의 편의성을 도모하고, 아울러 제작이 쉬운 효과를 기대할 수 있다.As described above, the structure of the conductor of the power cable is crimped and fixed to the crimping tool, and the crimping tool is inserted into the inner surface of the coupler to be pressed and fastened to form a simple structure.
