【考案の詳細な説明】
本考案はコンピユーター、音響機器等に使用さ
れるフラツトケーブルの改良に係わるものであ
る。フラツトケーブルは配線作業の容易性あるい
は占積率の良好性等の理由から多用されている
が、さらに端末処理を容易とするためケーブルの
長手方向の所定間隔毎に融着部を設けて成るもの
が提案されている。[Detailed Description of the Invention] The present invention relates to the improvement of flat cables used in computers, audio equipment, etc. Flat cables are widely used for reasons such as ease of wiring work and good space factor, but in order to further facilitate terminal processing, fused portions are provided at predetermined intervals along the length of the cable. something is proposed.
第１図はその一例を示すもので、複数本の絶縁
導体１を並べ、所定間隔毎に融着部２を設けたも
のである。 FIG. 1 shows one example, in which a plurality of insulated conductors 1 are lined up and fused parts 2 are provided at predetermined intervals.
この場合、融着部２は端末処理してコネクター
で接続されるため従つて融着部の導体ピツチの高
精度が要求されている。 In this case, the fused portion 2 is terminally processed and connected with a connector, and therefore high accuracy of the conductor pitch of the fused portion is required.
ところで従来この種フラツトケーブルを製造す
る場合、第４図に示すように一定温度にコントロ
ールされた金型３で、絶縁導体１を上下より押え
込んで熱融着している。 Conventionally, when manufacturing this type of flat cable, as shown in FIG. 4, the insulated conductor 1 is pressed down and heat-sealed using a mold 3 whose temperature is controlled at a constant temperature.
この場合融着時の熱により絶縁体４が膨張す
る。しかし金型３の内部でこの熱膨張分を吸収す
る場所がないため、この影響が導体５にあらわ
れ、導体の蛇行あるいは千鳥現象が発生し、規定
の導体ピツチ精度が出ない欠点があつた。 In this case, the insulator 4 expands due to heat during fusion. However, since there is no place inside the mold 3 to absorb this thermal expansion, this effect appears on the conductor 5, resulting in meandering or staggered behavior of the conductor, resulting in the disadvantage that the specified conductor pitch accuracy cannot be achieved.
特にこの導体ピツチ精度のみだれは、第３図に
示すような絶縁体４断面が角形の絶縁導体１の場
合顕著である。 This deterioration in conductor pitch accuracy is particularly noticeable in the case of an insulated conductor 1 whose insulator 4 has a rectangular cross section as shown in FIG.
本考案の目的は、前記した従来技術の欠点を解
消し、導体間ピツチ精度を向上できる熱融着形フ
ラツトケーブルを提供することにある。 SUMMARY OF THE INVENTION An object of the present invention is to provide a heat-sealable flat cable that can eliminate the drawbacks of the prior art described above and improve pitch accuracy between conductors.
すなわち本考案の要旨は、絶縁導体を複数本並
列配置し、長手方向の所定間隔毎に該絶縁導体を
熱融着して成るフラツトケーブルにおいて、該熱
融着部には傾斜状の非融着部を設けて構成された
ことを特徴とするフラツトケーブルにある。 In other words, the gist of the present invention is that a flat cable is formed by arranging a plurality of insulated conductors in parallel and heat-sealing the insulated conductors at predetermined intervals in the longitudinal direction. A flat cable is characterized in that it is configured with a fitting part.
第２図は本考案フラツトケーブルの一実施例を
示すもので、熱融着部２の中に傾斜状の非融着部
６を設けたものである。 FIG. 2 shows an embodiment of the flat cable of the present invention, in which an inclined non-welded part 6 is provided in the heat-sealed part 2.
非融着部６を構成する方法としては、熱融着金
型３に傾斜状のスリツトを設けておけば良く、こ
れにより絶縁体４の熱膨張分が金型３のスリツト
型で吸収され、そのため、導体５の蛇行及び千鳥
の発生が防止され、導体５のピツチ精度が向上で
きる。 The non-fused portion 6 can be formed by providing an inclined slit in the heat-sealing mold 3, so that the thermal expansion of the insulator 4 is absorbed by the slit shape of the mold 3. Therefore, meandering and zigzag of the conductor 5 can be prevented, and the pitch accuracy of the conductor 5 can be improved.
また非融着部６が傾斜状になつているため、融
着部２で絶縁体４を剥離しても絶縁導体１がばら
ばらになることはなく、フラツトケーブルの特性
を保持できるものである。 Furthermore, since the non-fused portion 6 is sloped, even if the insulator 4 is peeled off at the fused portion 2, the insulated conductor 1 will not fall apart, and the characteristics of a flat cable can be maintained. .
熱融着部２中に設けられた非融着部６は傾斜状
に連続させておく必要はなく、要は絶縁体４の熱
膨張を吸収すると共に直角方向に切断した場合、
絶縁導体１がばらばらにならないようなものであ
れば良い。 The non-fused portion 6 provided in the heat-fused portion 2 does not need to be continuous in an inclined manner.In short, if it absorbs the thermal expansion of the insulator 4 and is cut in a right angle direction,
Any material may be used as long as the insulated conductor 1 does not fall apart.
なお第３図において７は熱融着部、第４図の８
は金型３を加熱するヒータである。 In addition, in Fig. 3, 7 is the heat-sealed part, and in Fig. 4, 8 is the heat-sealed part.
