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 method of manufacturing a protection tube with a latch, the protection tube arranged such that a ridge and a groove are alternately and repeatedly arranged in an axial direction of the protection tube, the method comprising the steps of:
providing a die including
a protection tube cavity receiving the protection tube, and
a latch cavity communicating with the protection tube cavity and formed along an outline of the latch;

passing a shaft through the protection tube received in the protection tube cavity of the die;
clamping the die;
injecting melting resin within the die;
disconnecting the die upon the melting resin filled within the latch cavity being cured, so as to form the protection tube with the latch; and
removing the shaft from the protection tube with the latch,
wherein the protection tube cavity is formed into a circular shape along an outer diameter of the ridges of the protection tube,

wherein the protection tube cavity includes a plurality of circular projection strips arranged on an inner peripheral face of the protection tube cavity at both sides across the latch cavity, the plurality of circular projection strips being formed along an outline of the protection tube, and
wherein each circular projection strip of the plurality of circular projection strips mate with the groove when the die is in a closed state so as to create a seal that stems intrusion of the melting resin into the protection tube cavity.

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