Since the tension is not directly applied to the connection portion 5 and the connection portion 5 is sandwiched between the upper cover 10 and the lower cover 11 from both the upper and lower sides, disconnection or breakage due to peeling is less likely to occur. In addition, the flat electric wire 1 on which the pulling force easily acts has the rear part of the connection part 5 bent at the bending holding convex part 11b of the lower cover 11, and the bent part is clamped by the holding concave part 10d of the upper cover 10. Therefore, it is difficult for a tensile force to act on the connection portion 5.

Has the effect of Further, since the covers 20 and 21 are directly adhered to each other with the respective lead wires 4 sandwiched therebetween, the respective lead wires 4 can be positioned and held, and can be held between lines. Since the flat wire 1 is also sandwiched between the upper and lower covers, the flat wire 1 can be positioned and held.

る。As is apparent from the above description, the terminal connection structure of the wire harness according to the present invention is such that the upper cover and the lower cover sandwich the upper and lower sides of the connection portion between the flat electric wire and the lead wire. The holding portion holds the terminal base of the flat wire and the terminal base of the lead wire immovably. Therefore, since the tension is received by the holding portion and does not act on the connection portion, disconnection or breakage due to peeling is less likely to occur, and reliability is improved.

る利点を有するものである。In the case where the flat electric wire and the lead wire are bent before the connecting portion, it is possible to propose a tensile force acting directly on the connecting portion. In addition, since each wire is held by the wire holding claw and the wire holding groove at the bent portion and the lead wire side, insulation between wires can be performed at the same time by these holding portions, so that there is an advantage that a spacer or the like is not required separately. Things.

ることが出来、コストの低減を図ることが出来る。Further, since the lead wire is directly connected to the flat electric wire as described above, a special connector for connecting the flat electric wire is not required, and the harness can be constituted only by the general-purpose connector, thereby reducing the cost. Can be achieved.
