Electrical tubular motor device for e.g. blind, has sealing head only physically connected to electronic control assembly by using electrical cable so that positioning of control and gear motor assembly is compatible with cable flexibility

摘要

#CMT# #/CMT# The device has an electronic control assembly (24) with an end integrated in rotation and in translation without clearance with an end of a gear motor assembly (14). A sealing head (26) allowing the passage of a flexible electrical cable (28) is integrated in rotation and in translation with an end of an outer tube (12). The head is only physically connected to the control assembly by using the cable so that the positioning in rotation and translation of the assemblies with respect to the tube and the head is rendered compatible with flexibility of the cable. #CMT#USE : #/CMT# Used for a roller blind or blind. #CMT#ADVANTAGE : #/CMT# The sealing head is only physically connected to the electronic control assembly by using the electrical cable so that the control and gear motor assemblies are relatively positioned without necessitating the usage of mechanical clearance compensation device. The device therefore permits to precisely position two shaft rotation detectors so that the flawed operation of the detectors is eliminated. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a longitudinal cross sectional view of an electrical tubular motor device. 12 : Outer tube 14 : Gear motor assembly 24 : Electronic control assembly 26 : Sealing head 28 : Flexible electrical cable.
