第二殼體4設置於軟性排線2之後連接部22，軟性排線2之後連接部22設有複數後接點221，該些後接點221外露於第二殼體4。The second housing 4 is disposed on the connecting portion 22 after the flexible cable 2, and after the flexible cable 2, the connecting portion 22 is provided with a plurality of rear contacts 221, and the rear contacts 221 are exposed to the second housing 4.
單面合線排線5平行重疊設置於軟性排線2上，其一端電性連接第一殼體3，其另一端係沿著軟性排線2之長度方向延伸至軟性排線2之後連接部22且電性連接於第二殼體4，其中金屬層232介於軟性排線2與保護層231之間，單面合線排線5位於保護層231上，如此可得到較佳的防止電磁波干擾的效果。另一種選擇是，如第四圖所示，單面合線排線5之另一端係延伸至電性連接外露於保護層231之金屬層232。The single-side splicing wires 5 are arranged in parallel on the flexible cable 2, one end of which is electrically connected to the first casing 3, and the other end of which extends along the length direction of the flexible cable 2 to the flexible cable 2 and then the connecting portion 22 and electrically connected to the second casing 4, wherein the metal layer 232 is interposed between the flexible cable 2 and the protective layer 231, and the single-sided wire 5 is located on the protective layer 231, so that better electromagnetic waves can be obtained. The effect of interference. Alternatively, as shown in the fourth figure, the other end of the single-sided wire 5 extends to electrically connect the metal layer 232 exposed to the protective layer 231.
值得一提的是，單面合線排線5的結構係不同於軟性排線2的結構，單面合線排線5係特別強調僅有一絕緣層51及設於絕緣層51上之多條接地導線52，亦即接地導線52係整條外露於絕緣層51，其與軟性排線2利用上下絕緣層來上下壓合包覆複數條金屬導線的結構並不相同，且單面合線排線5之接地導線52係用來接地導通之用與軟性排線2之金屬導線用來傳輸訊號的作用也不相同，由於單面合線排線5之接地導線52的數量一定是少於軟性排線2之金屬導線的數量，所以單面合線排線5的寬度一般皆是小於軟性排線2的寬度。It is worth mentioning that the structure of the single-sided wire 5 is different from the structure of the flexible wire 2, and the single-side wire 5 particularly emphasizes only one insulating layer 51 and a plurality of wires provided on the insulating layer 51. The grounding conductor 52, that is, the grounding conductor 52 is entirely exposed to the insulating layer 51, and the structure of the flexible wiring 2 is used to press and cover the plurality of metal wires up and down by the upper and lower insulating layers, and the single-sided wire row is not the same. The grounding conductor 52 of the wire 5 is used for grounding conduction and the metal wire of the flexible cable 2 is used for transmitting signals, and the number of the grounding conductors 52 of the single-sided bonding cable 5 must be less than soft. The number of metal wires of the cable 2 is such that the width of the single-sided wire 5 is generally smaller than the width of the flexible cable 2.
在本實施例中，單面合線排線5之絕緣層51設置於保護層231上，該接地導線52介於保護層231與絕緣層51之間，其中單面合線排線5之接地導線52係延伸凸出於絕緣層51以形成一接觸端521，絕緣層51延伸至接近於上殼體33，接地導線52係延伸至上殼體33下面且其接觸端521電性接觸上殼體33，然不限於此，另一種選擇是，接地導線52係亦可延伸至上殼體33上面且焊接固定於上殼體33，如此使接地導線52之一端電性連接第一殼體3，接地導線52之另一端沿著軟性排線2之長度方向延伸至軟性排線2之後連接部22且電性接觸上殼體33。In this embodiment, the insulating layer 51 of the single-sided wire 5 is disposed on the protective layer 231. The ground wire 52 is interposed between the protective layer 231 and the insulating layer 51, wherein the grounding of the single-sided wire 5 is grounded. The wire 52 extends from the insulating layer 51 to form a contact end 521. The insulating layer 51 extends to be close to the upper casing 33. The grounding wire 52 extends below the upper casing 33 and the contact end 521 electrically contacts the upper casing. 33 is not limited thereto. Alternatively, the grounding wire 52 may extend over the upper casing 33 and be soldered to the upper casing 33 such that one end of the grounding conductor 52 is electrically connected to the first casing 3 and grounded. The other end of the wire 52 extends along the length direction of the flexible wire 2 to the connecting portion 22 after the flexible wire 2 and electrically contacts the upper casing 33.
此外，下殼體32之承載面321的左右兩側各設有一定位部322，軟性排線2左右兩側各設有一嵌合孔210，定位部322係嵌合於嵌合孔210，如此以將軟性排線2定位於下殼體32上。軟性排線2還包括有一補強片24貼設於該些前接點211之下側，補強片24係自該些前接點211之下側延伸至下殼體32及軟性排線2之間，補強片24與該些前接點211係形成與對接連接器互相搭接之對接部。於上殼體33面向於軟性排線2之一側設有一絕緣材6，該絕緣材6可避免上殼體33與軟性排線2之外露的金屬導線之間形成電性接觸而導致短路不良的問題。In addition, a positioning portion 322 is disposed on each of the left and right sides of the bearing surface 321 of the lower casing 32, and a fitting hole 210 is disposed on each of the left and right sides of the flexible cable 2, and the positioning portion 322 is fitted to the fitting hole 210, so that The flexible cable 2 is positioned on the lower housing 32. The flexible cable 2 further includes a reinforcing sheet 24 attached to the lower side of the front contact points 211, and the reinforcing sheets 24 extend from the lower side of the front contact points 211 to between the lower housing 32 and the flexible cable 2 The reinforcing piece 24 and the front contact points 211 form an abutting portion that overlaps with the mating connector. An insulating material 6 is disposed on one side of the upper casing 33 facing the flexible cable 2, and the insulating material 6 can prevent electrical contact between the upper casing 33 and the exposed metal wires of the flexible cable 2, thereby causing short circuit failure. The problem.
在本實施例中，軟性排線2及單面合線排線5係為各別單獨設立的元件，然不限於此，另一種選擇是，如第五圖所示，單面合線排線5之絕緣層51係可一體成型形成於軟性排線2之一側，且單面合線排線5係朝著金屬遮蔽層23反折，使單面合線排線5平行重疊設置於金屬遮蔽層23上，如第六圖所示，如此也可以得到類似於第一圖所示之電連接器1的結構，其中接觸端521延伸至上殼體33上面且焊接固定於上殼體33，然不限於此，也可以選擇將接觸端521延伸至上殼體33下面且電性接觸於上殼體33。In the present embodiment, the flexible cable 2 and the single-sided cable 5 are separately provided components, but are not limited thereto. Alternatively, as shown in the fifth figure, the single-sided cable is arranged. The insulating layer 51 of 5 can be integrally formed on one side of the flexible cable 2, and the single-sided wire 5 is folded back toward the metal shielding layer 23, so that the single-sided wire 5 is vertically overlapped and disposed on the metal. On the shielding layer 23, as shown in the sixth figure, a structure similar to the electrical connector 1 shown in the first figure can also be obtained, wherein the contact end 521 extends over the upper casing 33 and is welded and fixed to the upper casing 33, However, it is not limited thereto, and the contact end 521 may be extended to the lower surface of the upper casing 33 and electrically contacted with the upper casing 33.
值得一提的是，由於絕緣層51係一體成型形成於軟性排線2之一側，所以在軟性排線2在進行合線製程時，就已將絕緣層51形成於軟性排線2之一側，如此可節省製程並降低製造成本，以符合經濟效益。It is worth mentioning that, since the insulating layer 51 is integrally formed on one side of the flexible wiring 2, the insulating layer 51 is formed on one of the flexible cables 2 when the flexible wiring 2 is subjected to the bonding process. On the side, this saves process and reduces manufacturing costs to meet economic benefits.
綜上所述，本發明之電連接器係利用另外增設一單面合線排線於軟性排線上，使單面合線排線之一端電性連接第一殼體，其另一端係沿著軟性排線之長度方向延伸至軟性排線之後連接部以與第二殼體或金屬遮蔽層搭接，此單面合線排線的功能即在提供另外一條導電途徑，來達到消除電磁波干擾的目的，如此即可解決習知連接器結構之電磁波干擾的問題。此外，本發明之電連接器省略了絕緣本體，故可有效降低電連接器整體厚度，以利於薄型化並符合現今市場的需求。In summary, the electrical connector of the present invention utilizes an additional single-sided wire to be connected to the flexible cable, such that one end of the single-sided wire is electrically connected to the first casing, and the other end is along the other end. The length of the flexible cable extends to the flexible cable to connect the second housing or the metal shielding layer. The function of the single-sided wire is to provide another conductive path to eliminate electromagnetic interference. Therefore, the problem of electromagnetic wave interference of the conventional connector structure can be solved. In addition, the electrical connector of the present invention omits the insulating body, so that the overall thickness of the electrical connector can be effectively reduced to facilitate thinning and meet the needs of the market today.
