Embodiment Construction

[0060] like figure 1 As shown, a coil winder, which is initially used to wind a core 3 or coil 3' having a toroidal shape, is subsequently adjusted to receive a transmission 1 according to the invention, said coil winder Comprising a shuttle 2 passing through the passage opening 6 of the core or coil 3' and feeding the copper wire 5 to be wound around the core or coil 3', and three drive rollers 4a, 4b and 4c.

[0061] In the following description, the terms "core" 3 and "coil" 3' are used interchangeably to denote a part on which the winding is carried out, with the core 3 in the first coil through the copper wire 5. When the covering layer is completed, it becomes the coil 3'.

[0062] To drive the core 3 or coil 3' in rotation, the three drive rollers 4a, 4b and 4c have gripping surfaces which are placed in contact with the outer contour of the core 3 or coil 3'.

[0063] Drive rollers 4 a and 4 b are provided on both sides of the shuttle 2 , and a third drive roller 4 c ...

Abstract

The invention relates to a moving device 1 for a coil 3' core 3 or a coil 3' having a closed shape with an inner contour and an outer contour, including first and second rollers 4a, 4b able to rotate around a respective axis and intended to bear against one of the two contours of the core 3 or of the coil 3', means 20' for driving at least one of said rollers 4a, 4b in rotation, and retaining means 8a, 8b associated with each roller 4a, 4b, the retaining means 8a, 8b being subject to first return means 12 arranged to bring the first retaining means closer to the other of the two contours of the core 3 or the coil 3', as well as a coil winder equipped with such a device.

Description

technical field [0001] The invention relates to a device for moving a coil or a coil core having a closed shape with an inner contour and an outer contour, and a coil winder equipped with such a device. Background technique [0002] Coil winders typically manufacture coils by winding wire, typically copper, and electrically insulated, usually by painting, around a ferromagnetic core, in particular a ferromagnetic core made of soft iron . [0003] Due to the geometry of the core, the coil itself is closed, thereby defining the passage opening. [0004] These coils can be applied by including them in constituent parts of the Hall effect sensor. [0005] The principle of these sensors is based on the change in electrical current created by the entry of a metal rod into the channel opening of the coil. [0006] For this reason, the coils of these sensors most of the time have the shape of a circular ring, allowing a round rod or a rectangular rod to pass through the coil open...
