  • Patent number: 11462842
    Abstract: A harness is provided with one or more first wires each including a first core exposed portion, one or more second wires each including a second core exposed portion, and a bonded portion formed by welding the first and second core exposed portion(s). A total cross-sectional area of the second core(s) is equal to or less than ? of the sum of total cross-sectional areas of the first and second core(s). The bonded portion has two pairs of outer surfaces extending along an extending direction of the first and second wires and facing each other and a distance H between one pair of the outer surfaces (upper/lower surfaces), out of the two pairs of outer surfaces, is longer than a distance W between another pair of the outer surfaces (right/left side surfaces). The second core exposed portion(s) is/are arranged adjacent to the upper surface Up in the bonded portion.

  • Publication number: 20200194907
    Abstract: A harness 1 is provided with a wire 10 including a core 11 constituted by a plurality of strands and an insulation coating 12 coating the core 11, a single-core wire 20 including a body portion 21 and a wire fixing portion 23 extending from the body portion 21 and arranged to cover the core 11, and a splice terminal 30 including a bottom plate portion 31, the core 11 being arranged on the bottom plate portion 31, and a pair of wire barrel portions 32 extending from the bottom plate portion 31 and wound from outside the wire fixing portion 23. According to this configuration, since the wire fixing portion 23 of the single-core wire 20 is interposed between the core 11 and the wire barrel portions 32, it can be avoided that the core 11 protrudes from butting parts of the pair of wire barrel portions 32.
