본 발명은 주로 음극선관(CRT ; cathode ray tube)의 배면에 설치하여, 음극선관에서 유도되는 정전기나 고압의 유도전압을 방전시키기 위하여 접지선으로 사용되는 평편도금동선의 외측에 비닐튜브가 일정간격을 띠어 압출되도록 한 음극선관용 접지선의 압출방법 및 장치에 관한 것이다.The present invention is mainly installed on the back surface of the cathode ray tube (CRT; cathode ray tube), the vinyl tube to the outside of the flat-plated copper wire used as a ground wire to discharge the induced voltage of static electricity or high voltage induced in the cathode ray tube The present invention relates to a method and apparatus for extruding a ground wire for a cathode ray tube which is made to be extruded.

통상 음극선관의 배면에는 도면의 제1도에 나타낸 바와같이 배면에 내부는 평편도금동선(일명, 편조선)(P)으로 구성되고 노출되는 부분은 합성수지 등의 절연재를 씌워서 구성되는 접지선을 설치하여 끝단을 본체에 접지시켜서 사용케 되는데, 이는 음극선관(B)으로부터 발생되는 정전기나 고압부에서 유도되는 불필요한 전압성분을 유도 방전시킴으로서 주변 전자부품 등의 손상을 방지하게 되는바, 읍극선관(B)에는 약 25KV정도의 고압이 발생되므로 평편도금동선(P)이 그대로 노출될 경우 이와 또다른 도체사이에서 합선이나 방전이 일어날 우려가 있으므로 음극선관(B)으로부터 인출되는 평편도금동선에는 절연재를 씌워 줌으로써 방전을 방지하여야 하는 것이다.In general, as shown in FIG. 1 of the drawing, a cathode wire tube is provided with a flat-plated copper wire (aka braided wire) (P) inside, and an exposed part is provided with a ground wire formed by covering an insulating material such as synthetic resin. It is used by grounding the end to the main body, which prevents damage to surrounding electronic components by inductive discharge of static electricity generated from cathode ray tube (B) or unnecessary voltage components induced from high voltage part. Since high voltage of about 25KV is generated, short-circuit copper wire (P) is exposed as it is, there is a possibility that short-circuit or discharge may occur between this and other conductors. Should be prevented.

그러므로, 접지선은 최상의 유연성(굴신성)을 구유해야 함은 물론 불필요한 부분으로의 방전이 방지되야 하는 중요한 역할을 하게 되는 음극선관(B)의 제조에 있어 필수불가결한 요소인 것이다.Therefore, the ground wire is an indispensable element in the manufacture of the cathode ray tube B, which plays an important role of not only having the best flexibility (flexibility) but also preventing the discharge of unnecessary parts.

그리하여, 이러한 용도를 충족시키기 위하여 종래에는 도면의 제6도에 나타낸 바와같은 압출장치를 이용하여 접지선을 제조하였으나,이는 평편도금동선(P)을 압출기(2)를 경유시켜 외면에 합성수지가 일정두께로 피복되도록 하므로서 도면의 제7도와 같은 접지선을 제조하게 되는바, 이와같은 접지선은 통상 사용되는 전선과 같은 구조를 갖게되어 절연성은 우수한 반면 유연성이 떨어지게 되어 설치작업시 과다한 굴곡부위에서는 피복과 평편도급동선(P)이 마찰하여 피복이 파열되는 경우가 빈발하므로서 실용화되지 못하게 되었으며 더불어 양단에 단자결속을 위하여 피복을 박리시켜줌에 있어서도 그 박피작업이 평편도금동선(P)에 손상을 주지 않기 위하여는 상당한 숙련도가 요구되었던 것이다.Thus, in order to satisfy this use, a ground wire was conventionally manufactured by using an extrusion apparatus as shown in FIG. 6 of the drawing. However, the flat plated copper wire (P) was passed through the extruder (2) to have a predetermined thickness on the outer surface. Since the ground wire as shown in FIG. 7 is manufactured, the ground wire has the same structure as a commonly used wire, which is excellent in insulation and inferior in flexibility. Since the copper wire P is ruptured due to the friction of the copper wire P, it cannot be put to practical use. In addition, the peeling work does not damage the flat-plated copper wire P even when the sheath is peeled off for terminal bonding at both ends. Skill was required.

따라서, 유연성과 절연성을 동시 만족시키기 위하여 현재에는 평편도금동선(p)을 필요길이로 절단한후 이에 직경보다 다소 큰 내경을 갖는 합성수지 튜브를 별도로 절단하여 평편도금동선(P)의 외연에 삽입하여 사용하고 있으나, 이는 평편도금동선(P)과 합성수지류브를 별도로 제조하여 구비하여야 함에 따른 제조공정의 복잡함이 수반되었으며, 또한 합성수지튜브의 삽입을 용이하게 하기 위하여 지나치게 큰 내경을 갖는 합성수지튜브를 사용케 되므로서 작업시 평편도금동선(P) 과 합성수지튜브가 별도로 유동되어 작업효율이 떨어지게 됨은 물론, 설치가 완료된 후에도 합성수지튜브가 유동되므로서 평편도금동선(P)의 불필요한 부분이 노출되게 되어 방전형상이 일어나게 되는 등의 중대한 결함이 있었던 것이다.Therefore, in order to satisfy both flexibility and insulation at the same time, the flat-plated copper wire (p) is now cut to the required length, and then the synthetic resin tube having an inner diameter somewhat larger than the diameter is cut separately and inserted into the outer edge of the flat-plated copper wire (P). Although it is used, this entails the complexity of the manufacturing process as the flat-plated copper wire (P) and the synthetic resin ribs must be manufactured and provided separately, and also used a synthetic resin tube having an excessively large inner diameter in order to facilitate the insertion of the synthetic resin tube. As a result, the flat plating copper wire (P) and the synthetic tube are flowed separately during operation, which lowers the work efficiency, and the synthetic tube flows even after the installation is completed, so that unnecessary portions of the flat plating copper wire (P) are exposed to discharge shape. There was a serious flaw such as what happened.

본 발명은 이와같은 종래의 제반 결함을 완전히 일소한 것으로, 평편도금동선의 외연에 일정간격을 띠어 합성수지튜브를 압출하므로서 유연성과 절연선을 동시에 층족시킬수 있도록 함은 물론 제조공정의 단순화와 작업효율을 향상시킨 것으로서, 이를 첨부한 도면을 참조하여 상세히 설명하면 다음과 같다.The present invention completely eliminates such conventional defects, and extrudes the synthetic resin tube at regular intervals on the outer edge of the flat-plated copper wire, thereby allowing the flexibility and the insulated wire to be stratified at the same time, as well as simplifying the manufacturing process and improving work efficiency. As will be described in detail with reference to the accompanying drawings as follows.

기 제조된 평편도금동선(P)을 권취한 권위드럼(1)을 전방에 설치하여 이로부터 공급되는 평편도금동선(P)이 압출기(2)를 경유하므로서 외연에 합성수지 피복이 형성되도록 하고 이를 수조(5)를 경유시켜 성형한후 권취드럼(7)에 권취토록 한 것에 있어서, 권취드럼(1)과 압출기(2)의 사이에 통상의 장력조절장치(8)를 설치하여 압출기(2)로 공급되는 평편도금동선(P)의 장력과 공급속도를 제어토록 하고 압출기(2)의 다이스(3) 진입측에는 콤프레셔(9)로부터 공급되는 공기가 호오스(10)를 통해 호퍼(4)로부터 용융공급되는 합성수지원료와 평편도금동선(P)의 사이로 진입되도록 하고, 다이스(3)의 출구측에는 합성수지원료와 평편도금동선(P)의 사이로 중앙에 통공(11')이 형성된 조절링(11)을 설치하여 조절링(11)은 가동본체(12)에 간격조절구(13)가 나사결합하므로서 간격조절구(13)와 다이스(3)사이로 압출되는 합성수지튜브(T)와 평편도금동선(P)의 사이에 일정간격(G)이 유지되도록 하며, 압출기(2)와 수조(5)의 사이에 교정가 형기(15)를 설치하여 이의 안내공(16)을 통해 아직 경화되지 않은 상태의 합성수지튜브(T)가 외연에 압출된 평편도금동선(P)이 경유되도록 하되 콤프레셔(17)로부터 공급되는 공기가 안내공(16)과 합성수지튜브(T)의 외연 사이로 진입되도록하여 합성수지튜브(T)의 내부로 공급되는 공기와 균형을 맞추어 합성수지튜브(T)를 원활하게 통과되도록 함과 동시에 합성수지튜브(T)가 변형됨이 없이 교정되오록 1차로 가형, 교정한 다음 수조(5)를 경유토록하여 2차로 냉각, 성형하므로서 접지선(E)을 제조하게 되는 것이다.An authority drum (1) wound around the previously manufactured flat-plated copper wire (P) is installed in the front so that the flat-plated copper wire (P) supplied therefrom is formed through the extruder (2) to form a synthetic resin coating on the outer edge thereof, and the tank After forming through (5) and wound up in the winding drum (7), a normal tension control device (8) is provided between the winding drum (1) and the extruder (2) to the extruder (2). The tension and supply speed of the flat plated copper wire (P) to be supplied are controlled, and air supplied from the compressor (9) is supplied melted from the hopper (4) through the hose (10) on the inlet side of the die (3) of the extruder (2). To enter between the synthetic water support fee and the flat plated copper wire (P), and the adjustment ring (11) having a through hole (11 ') formed in the center between the synthetic water support fee and the flat plated copper wire (P) at the exit side of the die (3) The adjusting ring 11 is screwed into the spacer 13 to the movable body 12 A predetermined distance G is maintained between the synthetic resin tube T and the flat plated copper wire P extruded between the gap adjusting device 13 and the die 3, and between the extruder 2 and the water tank 5. Is installed in the correction mold 15 to the through-hole 16, the synthetic resin tube (T) is not yet hardened to pass through the flat plated copper wire (P) extruded to the outer edge, but is supplied from the compressor (17) Air is allowed to enter between the guide hole 16 and the outer edge of the synthetic tube (T) to balance the air supplied into the synthetic tube (T) to smoothly pass through the synthetic tube (T) and at the same time the synthetic resin tube ( T) is to be calibrated without deforming first, and then the ground wire (E) is manufactured by secondly cooling and molding through the water tank (5).

도면중 미설명부호 14는 조절링(11)을 압출기(2)에 고정하기 위한 고정봉 으로서, 통상 튜브제조용 코어를 고정시키기 위한 것이며, 이는 코어의 위치를 전후방향으로 이동시키기 위하여 전·후진되도록 수성되어 있다.In the figure, reference numeral 14 denotes a fixing rod for fixing the adjusting ring 11 to the extruder 2, which is usually used to fix a core for manufacturing a tube, so that the core is moved forward and backward to move the position of the core in the front and rear directions. It is aqueous.

이와같은 본 발명은 도면의 제3도에 나타낸 바와같이 별도의 제조장치(도시하지 않음)에 의해 제조되어 권취드럼(1)에 권취된 평편도금동선(P)을 장력 조절장치(8)를 경유시켜 압출기(2)로 공급하에 되면 도면의 제4도에 나타낸 바와같이 압출기(2)는 호퍼(4)에 수용된 합성수지원료를 용융시켜 평편도금동선(P)의 외연으로 합성수지튜브(T)를 압출하게 되는데, 이때 합성수지튜브(T)의 사이로 콤프레셔(9)가 호오스(10)를 통해 적정 압력의 공기를 공급하게 되므로서 함성수지튜브(T)가 찌그러지거나 평편도금동선(P)과 접촉하지 않도록 하게 함은 물론, 조절링(11)이 합성수지튜브(T)를 평편도금동선(P) 과 일정간격(G)을 유지하도록 하게 되고 계속해서 다이스(3)를 경유하면서 합성수지튜브(T)가 소정의 외경을 갖게되며, 소정의 외경을 갖게된 접지선(E)은 도면의 제5도에 나타낸 바와같이 교정가형기(15)의 안내공(16)을 경유하게 되면서 전체적으로 균일하고도 매끄러운 상태로 교정, 가형하게 되며, 계속해서 수조(5)를 경유하면서 냉각, 성형되어 도면의 제2도에 나타낸 바와같은 접지선(E)이 권취드럼(7)에 권취되게 되는 것이다.The present invention as described in FIG. 3 of the drawings is made by a separate manufacturing device (not shown) and is wound on the flat plating copper wire (P) wound on the winding drum (1) via the tension control device (8). When it is supplied to the extruder 2, the extruder 2 melts the synthetic water support material contained in the hopper 4 and extrudes the synthetic resin tube T by the outer edge of the flat plating copper wire P as shown in FIG. In this case, the compressor (9) is supplied between the synthetic resin tube (T) through the hose (10) to supply the air of the appropriate pressure so that the resinous resin tube (T) is not crushed or contact with the flat plating copper wire (P) Of course, the adjustment ring 11 is to maintain the synthetic tube (T) with a flat plated copper wire (P) and a constant distance (G) and the synthetic resin tube (T) is predetermined while passing through the die (3) It has an outer diameter of and the ground wire (E) having a predetermined outer diameter is As shown in FIG. 5, the guide hole 16 of the straightening molder 15 is calibrated and shaped in a uniform and smooth state as a whole, and is subsequently cooled and molded while passing through the water tank 5. The ground wire E as shown in FIG. 2 is to be wound around the winding drum 7.

여기에서, 간격(G) 조절을 위해 사용되는 조절링(11)은 도면의 제4도에 나타낸 바와같이 중앙에 통공(11')을 평편도금동선(P)의 직경보다 크게 형성하므로서 콤프레셔(9)로부터 공급되는 공기가 이를 통해 원활이 통과할수 있게 되는바, 간격(G)의 조절을 위하여는 간격조절구(13)의 외경을 다양한 규격으로 구비함으로써 구현될수 있는데 간격조절구(13)의 외경이 큰 것을 가동본체(12)에 나사결합하게 되면 넓은 간격(G)의 합성수지튜브(T)를 압출할수 있게되고, 외경이 작은 것을 가동본체(12)에 나사결합하게 되면 좁은 간격(G)의 합성수지튜브(T)를 압출할수 있게 되며, 조절링(11)이 고정봉(14)에 의해 전후진 되도록 되어 있어 실선도시와 같이 조절링(11)을 다이스(3)와 거리를 멀게하게 되면 합성순지튜브(T)의 압출두께가 두꺼워지게 되는 반면 점선도시와 같이 거리를 가깝게 하게 되면 합성수지튜브(T)의 압출두께를 얇게 할수 있게 되는 것이다.Here, the adjustment ring 11 used for adjusting the gap (G) is a compressor (9) by forming a through hole (11 ') in the center larger than the diameter of the flat plated copper wire (P) as shown in FIG. The air supplied from the) is to be able to pass through it smoothly, for the adjustment of the gap (G) can be implemented by having the outer diameter of the gap adjusting device 13 in various standards, the outer diameter of the gap adjusting device (13) When screwing the larger one to the movable main body 12, the synthetic resin tube T can be extruded with a wider gap G, and when the smaller outer diameter is screwed to the movable main body 12, the narrower gap G can be extruded. Synthetic resin tube (T) can be extruded, and the adjusting ring 11 is moved forward and backward by the fixing rod 14, so as to move the adjusting ring 11 away from the die 3 as shown in the solid line, While the extrusion thickness of the pure paper tube (T) becomes thick, If the distance is close, the extrusion thickness of the synthetic resin tube (T) can be made thin.

한편, 교정가형기(15)의 안내공(16)으로 진입되는 접지선(E)은 도면의 제5도에 나타낸 바와같이, 합성수지튜브(T)가 아직 경화되지 않고 누글누글한 상태이어서 처짐현상이 발생하여 안내공(16)의 내벽에 눌러붙게 될 것이다. 이러한 현상은 콤프레셔(17)에서 공급되는 공기로서 해소될수 있는바, 이는 콤프레셔(17)로부터 공급되는 공기에 의해 합성수지튜브(T)가 외방으로 벌어지려는 작용을 하고 있는 상태에서 합성수지튜브(T)의 외연과 안내공(16)의 사이로 콤프레셔(17)가 공기를 압송하므로서 이들사이에 미세한 공기막이 형성되어 합성수지튜브(T)가 안내공(16)을 원활하게 통과할 수 있게 되는데, 이때 양측 콤프레셔(9)(17)의 공기압을 적절히 조절하여 주어야 함은 물론, 합성수지튜브(T)가 교정되기 이전에 냉각, 성형되는 것을 방지하기 위하여 콤프레셔(9)(17)로부터 공급되는 공기를 적절한 온도로 가열시켜줌이 바람직하며 합성수지튜브(T)의 재질에 대응하여 경우에 따라서는 교정가형기(15)를 별도의 가열장치(도시한바 없음)로서 적정온도로 가열하여 주는 것이 바람직하다.Meanwhile, as shown in FIG. 5 of the drawing, the ground wire E entering the guide hole 16 of the straightening molder 15 is not yet cured and the resin tube T is not cured, and sag occurs. Will be pressed to the inner wall of the guide hole (16). This phenomenon can be eliminated as air supplied from the compressor 17, which is a synthetic resin tube (T) in the state that the synthetic resin tube (T) acts to spread outward by the air supplied from the compressor (17). Compressor 17 presses the air between the outer edge and the guide hole 16 of the fine air film is formed between them so that the synthetic resin tube (T) can pass through the guide hole 16 smoothly, at this time both compressors In addition to adjusting the air pressure of (9) and (17), the air supplied from the compressors (9) and (17) may be adjusted to an appropriate temperature in order to prevent the synthetic resin tube (T) from being cooled or molded before being calibrated. It is preferable to heat it. In some cases, it is preferable to heat the calibrating molder 15 to a proper temperature as a separate heating device (not shown) corresponding to the material of the synthetic resin tube (T). All.

이와같이 제조된 접지선(E)은 도면의 제1도에 나타낸 바와같이 음극선관(B)의 규격에 맞추어 필요길이로 절단한후 접속을 위하여 양단에 일정길이로 합성수지큐브(T)를 박리시킴으로서 평편도금동선(P)을 노출시켜야 할 것인바, 합성수지튜브(T)는 평편도금동선(P)과 일정간격(G)을 유지하고 있으므로 별도의 공구를 이용하더라도 평편도금동선(P)에 손상을 주지 않고도 용이하게 박리시킬수 있게 되는 것이다.The ground wire (E) manufactured as described above is cut flat to the required length according to the specification of the cathode ray tube (B) as shown in FIG. 1, and then flat plated by peeling the synthetic resin cube (T) at both ends for connection. The copper wire (P) should be exposed, so the synthetic tube (T) maintains the flat plating copper wire (P) and a constant distance (G), so even if a separate tool is used, the flat plating copper wire (P) is not damaged. It will be easy to peel off.

이상에서와 같이 본 발명은 제조공정을 단순화 함은 물론 평편도금동선과 합성수지튜브가 일정간격을 유지토록 하므로서 유연성과 절연성을 동시에 만족시킬수 있게 되며, 설치 사용 또한 간편, 용이하게 할수 있게 되는 등의 지대한 효과를 제공케 되는 것이다.As described above, the present invention not only simplifies the manufacturing process but also maintains a constant distance between the flat-coated copper wire and the synthetic tube, so that flexibility and insulation can be simultaneously satisfied, and installation and use can be made simple and easy.
