본 고안은 컴퓨터 및 프린터 주변기기, OA사무기기, 진공청소기등에 활용되는 꽂음플럭용 캡타이어 전원코드에 관한 것으로, 특히 코드내에 매입된 도체들의 구조개량으로 높은 비(非)인장강도 및 비 탈성율, 낮은 신장율등의 특성을 갖게 하여, 코드의 유연성과 강도를 높게 한 것에 의해 반복 사용시 유발되는 굴곡변형 개선과 아울러 고 인장력에도 견딜 수 있게 한 꽂음플럭용 캡타이어 전원코드에 관한 것이다.The present invention relates to a cap-tire power cord for plug plugs used in computer and printer peripherals, OA office equipment, vacuum cleaners, and the like. In particular, high non-tensile strength and non-degradation rate can be achieved by improving the structure of conductors embedded in the cord. The present invention relates to a cap-tire power cord for plugging plugs that has a property such as low elongation, and is capable of withstanding high tensile strength as well as improving bending deformation caused by repeated use of the cord by increasing the flexibility and strength of the cord.

종래 캡타이어 전원코드의 구조 일예를 제2도에 표시하고 있다. 종래 코드는, 코드의 시이즈(5)내부에 매입된 수가닥의 도체들(1a,1b,1c)은 그 주위가 절연체(2a,2b,2c)로 피복된 후 연합되며, 각 도체들(1a,1b,1c)사이에는 혼방사, P·P사, 마닐라사 등으로 이루어진 개재사(3)가 배치된다. 또한 이들은 다시 부직포나 알루미늄으로 이루어진 테이프(4)로 감싸져서 밀착되는 상태로 이루어져 있다. 이때문에 상기 도체들(1a,1b,1c)은 개재사(3) 및 테이프(4)로 인한 연합작업성이 떨어지고 있다. 또한 꽂음플럭에 접속하여 연결부착코져 전원코드를 가공시 내부에 개재된 개재사(3) 및 테이프(4)를 일일히 제거해야만 하는 번거로움이 있고, 개재사(3) 및 테이프(4)로 인해 시이즈(5)에 굴곡변형이 발생되는 결점이 있다.An example of the structure of a conventional cab tire power cord is shown in FIG. In the conventional cord, the male conductors 1a, 1b, 1c embedded in the sheath 5 of the cord are joined after their surroundings are covered with the insulators 2a, 2b, 2c, and the respective conductors ( Between 1a, 1b, and 1c, an intervening yarn 3 made of blended yarn, P-P yarn, manila yarn, or the like is disposed. In addition, they are made of a state of being closely wrapped by being wrapped with a tape 4 made of nonwoven fabric or aluminum. Because of this, the conductors 1a, 1b, 1c are inferior in workability due to the intervening yarn 3 and the tape 4. In addition, there is a hassle to remove the intervening yarn (3) and the tape (4) interposed inside when processing the power cord attached to the connection plug by plugging into the plug plug, with intervening yarn (3) and tape (4) Due to this, there is a drawback that the bending deformation occurs in the siege 5.

본 고안은 상기 결점들을 해소키 위하여 안출한 것으로, 심재로써 고강도와 유연성을 유지하고, 고 온도와 내약품성이 우수하며, 보통 환경과 조건에서는 연소되지 않고, 낮은 영하의 극지 온도에서도 잘 부서지지 않은 아라미드섬유를 사용함에 의해, 코드의 외관이 굴곡변형되는 일이 없게한 꽂음플럭용 캡타이어 전원코드를 제공하는데 있다.The present invention devised to solve the above-mentioned defects, and maintains high strength and flexibility as a core material, excellent in high temperature and chemical resistance, does not burn in normal environment and conditions, and does not break well at low sub-zero polar temperature An aramid fiber is used to provide a plug tire power cord for plugging plug in which the appearance of the cord is not deformed.

상기 목적은 수지로 피복된 다심의 도체화, 도체사이에 배치된 개재사 및 이들을 밀착되게 감싸는 테이프와, 테이프 외부를 피복하는 시이즈로 구성된 캡타이어 전원코드에 있어서, 다심의 도체 중심부에 매입되는 아라미드섬유사, 상기 도체들의 표면주위를 절연물질로 1차 압출성형하여 피복되게 한 제1절연체, 및 절연체들을 연합한 후 절연물질로 2차 압출성형함에 의해 그 절연체와 일체로 되게끔 외주전체를 피복하는 제2절연시이즈를 포함하는 것을 특징으로 하는 꽂음플럭용 캡타이어 전원코드에 의하여 달성된다.The above object is to be embedded in the center of the conductor of the core in the cap-tire power cord composed of a conductor of the multi-core coated with resin, interposed yarns disposed between the conductors, a tape covering them tightly, and a sheath covering the outside of the tape. Aramid fiber yarns, the first insulator to be coated by the primary extrusion molding the surface of the conductors with an insulating material, and the entire outer periphery to be integral with the insulator by assembling the insulators and then secondary extrusion molding with the insulating material It is achieved by a cap tire power cord for plugging plug, characterized in that it comprises a second insulating sheath covering.

이하에서 본 고안의 바람직한 실시예에 따른 꽂음플럭용 캡타이어 전원코드를 첨부한 도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, the plug tire power cord for plug plug according to a preferred embodiment of the present invention will be described in detail.

제1a도는 본 고안에 의핸 캡타이어 전원코드의 일부 절결 사시도를 나타낸 것이다. 본 고안의 전원코드는 다수개의 세선(細線)이 집합되어 이루어진 동선(銅線)재질의 도체들(10a,10b,10c)을 구비한다. 상기 도체들(10a,10b,10c)의 각 중심부에는 아라미드섬유사들(11a,11b,11c)이 매입된다.Figure 1a shows a partially cutaway perspective view of the cap tire power cord according to the present invention. The power cord of the present invention includes conductors 10a, 10b, and 10c of copper wire material formed by a plurality of thin wires. Aramid fiber yarns 11a, 11b, and 11c are embedded in the central portions of the conductors 10a, 10b, and 10c.

상기 아라미드섬유사들(11a,11b,11c)이 매입된 각 도체들(10a,10b,10c)의 외표면에는 합성수지 절연물질로써 1차 압출성형하여 도포함에 의해 제1절연체들(12a,12b,12c)이 형성된다. 상기 제1절연체들(12a,12b,12c)로 도포된 2심 또는 3심의 각 도체들(10a,10b,10c)을 서로 연합한 후 다시 합성수지로써 2차 압출성형함에 의해, 그 전체 외주표면으로는 원형의 제2절연시이즈(14)가 형성된다.The first insulators 12a, 12b, and 12c are formed by first extrusion molding the outer surface of each of the conductors 10a, 10b, and 10c into which the aramid fiber yarns 11a, 11b, and 11c are embedded. ) Is formed. Each of the two or three core conductors 10a, 10b, and 10c coated with the first insulators 12a, 12b, and 12c are combined with each other, and then secondly extruded with synthetic resin to the entire outer peripheral surface thereof. The second insulating siege 14 of circular shape is formed.

제1b도는 a도의 I-I선 방향에 따른 단면도를 나타낸 것이다. 상기 제1절연체들(12a,12b,12c)은 그 주위를 피복하고 있는 시이즈(14)와 일체로 된다. 그 이유는 제2절연시이즈(14)를 구성하는 합성수지가 절연체들(12a,12b,12c)의 외표면에서 2차로 압출성형되기 때문이다.FIG. 1B is a cross-sectional view taken along the line I-I of FIG. The first insulators 12a, 12b, and 12c are integral with the size 14 covering their surroundings. This is because the synthetic resin constituting the second insulating size 14 is extruded secondly from the outer surface of the insulators 12a, 12b, 12c.

따라서, 절연체들(12a,12b,12c)은 시이즈(14)내에서 비틀림등의 위치변형됨이 없이 항시 균형유지를 하게 된다.Therefore, the insulators 12a, 12b, 12c are always balanced in the size 14 without being distorted or distorted.

이상과 같이 본 고안의 캡타이어 전원코드에 의하면 각 도체들의 중심부에는, 고강도와 유연성을 유지하며 고 온도와 내 약품성이 우수하고, 보통환경과 조건에서는 연소되지 않고, 낮은 영하의 극지 온도에서도 쉽게 파손되지 않는 아라미드섬유사를 매입함과 아울러, 상기 도체들의 외표면은 1차, 2차에 걸쳐서 합성수지로써 압출성형하여 일체로된 절연층을 성형하고 있다. 이때문에 코드를 플럭에 부착시 절연체만을 제거하면 되는 작업성의 편리한 효과가 있다.As described above, according to the CapTire power cord of the present invention, in the center of each conductor, it maintains high strength and flexibility, and has high temperature and chemical resistance, does not burn in normal environments and conditions, and easily breaks even at low-zero polar temperature. In addition to embedding the aramid fiber yarn, the outer surface of the conductors is molded by extrusion molding the synthetic resin over the first and second parts to form an integral insulating layer. This has the convenience of workability, where only the insulator is removed when the cord is attached to the plug.

더우기 아라미드사와 1,2차의 일체로된 절연체로 인해 높은 비인장강도와 높은 비탄성율, 그리고 낮은 신장율등의 특성을 갖게 되어, 코드의 유연성과 강도를 높여 주므로써 반복사용시 코드의 외관이 굴곡변형되는 일이 전연 없는 효과를 주는 것이다.Moreover, the aramid yarn and the primary and secondary insulators have characteristics such as high specific tensile strength, high inelasticity, and low elongation, which increase the flexibility and strength of the cord, resulting in flexion and deformation of the cord during repeated use. Work has no effect.
