Description

  The present invention relates to a protector covering a periphery of a linear body group such as an electric wire group and a wire harness including the same.

  A wire harness in a vehicle typified by an automobile is required not to break an electric wire due to contact with surrounding members and heat received from the surroundings. Therefore, a hard protector that covers the periphery of the electric wire may be provided in the wire harness of the vehicle.

  Moreover, when the electric wire group of a wire harness has a branch part, that is, the electric wire group may have a main line part including a plurality of electric wires and a branch line part including one or a plurality of electric wires branched from the main line part. is there. In this case, since it is necessary to maintain the electric wire which comprises a branch line part in the branch part in the state curved with comparatively small curvature, the branch part of an electric wire group occupies a larger volume than another part.

  Therefore, in order to accommodate the branch portion of the electric wire group in the protector, a large protector is required. However, if the protector has a part that accommodates the main line part and a part that supports the branch line part along the outer edge of the part that accommodates the main line part, the size of the protector is avoided as a result. be able to.

  For example, the protector shown in Patent Document 1 includes a main body in which a first housing groove and a second housing groove are formed, and a lid that closes the first housing groove. In the protector shown in Patent Document 1, the first housing groove can accommodate the main line portion of the wire group, and the second housing groove can accommodate the branch line portion of the wire group. Therefore, if the protector shown by patent document 1 is employ | adopted, it will become possible to arrange | position the branch part in an electric wire group out of a protector, and the enlargement of a protector can be avoided.

  Moreover, in the protector shown by patent document 1, the engaging part of a main body and the latching | locking part of a cover body are mutually fastened, and they have blocked a part of opening of the 2nd accommodation groove. In this case, the engaging portion and the locking portion serve as a retaining portion that prevents the electric wire from being pulled out from the second housing groove. Therefore, a narrow gap between the edge of the second housing groove and the engaging portion (a retaining portion) serves as an insertion port for inserting an electric wire such as a branch line portion into the second housing groove.
