Abstract

A protection tube with latch in which a latch that is formed engageable with an attachment hole of a panel is molded integral with a protection tube that receives an electric wire, and a manufacturing apparatus of the protection tube with latch. The protection tube with latch includes a latch to be engaged with the attachment hole of the panel having the electric wire wired therein disposed on an outer peripheral face of the protection tube that is formed tubular and receives the electric wire.

First claim

The invention claimed is:

1. A manufacturing apparatus of a protection tube with latch, comprising:
a die including:
a protection tube cavity receiving the protection tube;
a latch cavity communicating with the protection tube cavity and formed along an outline of the latch;

a shaft arranged to pass through the protection tube received in the protection tube cavity of the die; and
a positioning device configured to move the shaft with respect to the die so as to adjust a molding position of the latch to be molded on an outer peripheral face of the protection tube,
wherein the shaft is configured to be removed out from the protection tube after the latch is molded on the outer peripheral face of the protection tube, and wherein
a circular projection strip on an inner peripheral face of the protection tube cavity is formed along an outline of the projection tube and abuts onto the outer peripheral face of the protection tube so as to stem intrusion of melting resin into the protection tube cavity.

2. The manufacturing apparatus of the protection tube with latch as claimed in claim 1 , wherein the shaft is provided with a projection strip projecting from an outer circumferential face of the shaft and extending in an axis direction of the shaft.
