    • PROBLEM TO BE SOLVED: To improve waterproofness (rust-prevention performance) of a core wire exposed part of an electric wire in the core wire crimp part of a terminal.SOLUTION: In a crimp-style terminal 1 including a pair of core wire crimp pieces 7 on the front side and a pair of insulation coating crimp pieces 6 on the rear side on both left and right sides of a substrate part 5, electric wire cover members 14, 15 comprising a bottom plate part 19 along the substrate part and folded parts 17, 21 folded backwards from the bottom plate part are provided, the core wire part 13 of an electric wire 11 is inserted forward to a gap 20 between the folded parts and the bottom plate part, and the folded parts are crimped by the core wire crimp pieces together with the core wire part. A part including both sides at the front end of the gap is covered with the pair of core wire crimp pieces or a sidewall 28 when crimping the electric wire. The rear end part 21a of the folded part 21 is extended from the core wire part of the electric wire to an insulation coating part 12. Or, an electric wire cover member 16 comprising a cylindrical part 23 along the substrate part and a sealing part 25 covering the front opening 24a of the cylindrical part is provided, and the core wire part 13 of the electric wire 11 is inserted forward inside the cylindrical part and crimped together with the cylindrical part by the pair of core wire crimp pieces.
    • 要解决的问题:提高端子的芯线压接部分中的电线的芯线露出部分的防水性(防锈性能)。 解决方案:在包括前侧的一对芯线压接片7和在衬底部分5的左侧和右侧的后侧上的一对绝缘涂层压接片6的压接式端子1中, 设置有沿着基板部分的底板部分19和从底板部分向后折叠的折叠部分17,21的电线覆盖部件14,15,电线11的芯线部分13向前插入间隙20 在折叠部分和底板部分之间,并且折叠部分被芯线卷曲件与芯线部分一起卷曲。 包括在间隙前端的两侧的部分被一对芯线压接部件或压接电线时的侧壁28覆盖。 折叠部分21的后端部21a从电线的芯线部分延伸到绝缘涂层部分12.或者,包括沿着基板部分的圆柱形部分23和密封部分25的电线覆盖部件16 覆盖圆筒形部分的前开口24a,电线11的芯线部分13在圆柱形部分的前方插入,并且通过一对芯线压接片与圆柱形部分一起压接在一起。 版权所有(C)2012,JPO&INPIT
