Wire harness

The purpose of the present invention is to provide a wire harness capable of reliably accommodating and fixing a joint connector in an electrical junction box. The frame of the wire harness (WH) has a partition wall (31). The partition wall (31) is provided with a locking part (33), and the locking part (33) locks the joint connector (10) accommodated in the partition space part (3aa) from the opening part (3b) on the lower side. When the electronic component block (6) is fixed to the frame (3) by the fixing portion (32), the locking portion (33) is located below the electronic component block (6), and when the frame (3) is viewed from the opening (3b) on the lower side, the locking portion (33) is separated from the electronic component block (6) in an orthogonal direction orthogonal to the insertion direction (first height direction Z1) of the electronic component block (6). 本发明的目的在于提供一种能够将接头连接器可靠地容纳并固定于电气接线箱内的线束。线束(WH)的框架具有分隔壁(31)。分隔壁(31)具有卡止部(33)，该卡止部(33)将从下方侧的开口部(3b)容纳于分区空间部(3aa)的接头连接器(10)卡止。在电子部件块(6)被固定
