Abstract

Disclosed is an electric wire laying head device capable of changing easily the deriving direction of an electric wire from a head unit and suppressing more reliably the float of the electric wire when the electric wire is laid.  The electric wire laying head device for laying an electric wire on a subject to be layed, comprises a head unit arranged to face the subject, and an electric wire let-off unit capable of letting off the electric wire toward the head unit.  The head unit has a derivation port formed with a larger inner diameter than the outer diameter of the electric wire, and a bend allowing space formed on this side of the derivation port for allowing the bend of the electric wire.

Description

technical field [0001] The present invention relates to a technology for manufacturing circuit elements having wires laid therein, such as internal wiring structures of devices such as electrical junction boxes and automatic transmissions for vehicles. Background technique [0002] In the past, as the head structure of the wire wiring device, there are the following structures: a structure in which the electric wire is supplied through a straight hole (refer to the prior art of Patent Document 1), and a structure in which the electric wire is bent and guided outward by a guide roller (refer to the structure of the patent document 1). Prior Art, Patent Document 2) and the like. [0003] Patent Document 1: Japanese Publication No. 7-40260 [0004] Patent Document 2: Japanese Patent Application Laid-Open No. 10-22495 [0005] However, in the former prior art, the wires led out from the straight holes are bent with a relatively small bending radius and routed to the wiring boa...
