Abstract

Coil carrier plug-in system characterized in that it consists of corner elements A, connecting elements of different lengths B, extension elements of different lengths, angle extension or connecting elements G, middle elements, double middle elements, spacer elements for other profiles H, as well as edge profiles in cross section "M-shaped" and from spacer profiles There is an X-shape for the pluggable connection of a coil former which is variable in all spatial directions.

Description

The registered bobbin connector system owns opposite the prior art considerable advantages in terms of stability, processability and Economics.

Due to the changed outer contour and the conical Verrastungsöffnungen in corner element A, the heavily used points X have been considerably reinforced.

It was also limited the groove for receiving the distance profiles using a connecting bar the fit of the edge profile improves and at the same time the rear wall of the Reinforced corner element.

The ¾ circular extension E in the receiving opening for the Edge profile improves the spring effect of the short legs and prevents destruction of the corner element through the frequently existing strong burr of the corner profiles.

The rounding of the edges in the insertion opening F facilitates the positioning of the distance profiles and prevents injuries in front.

The conical shape with rounded Tip C enables horizontal merging for locking the connection and extension elements with the corner element.

This makes partial automation and handicapped accessible Working method enables.

The spacer H allows it to be smaller or different to process shaped profiles in the same corner element.

With air-cooled electrical coils, such as. It is important to transformers that by chimney effect the heat is dissipated between the coil and the iron core.

The previously known connectors and Renewals close the opening and hinder the chimney effect and were therefore after completion away.

The angle extension element makes it possible in connection with straight connection and extension elements as well as the Corner elements to create a frame that does not have the chimney effect hindered and can therefore remain in the coil.

In the case of particularly large coils, instead of Connecting and extension elements, Middle elements or double middle elements are used support the winding on the one hand by the long leg and on the other hand fixes the distance profiles.

The edge profiles with an "M-shaped cross section" improve on the one hand due to the chimney effect in the two fillets the heat dissipation and on the other hand the drinking properties the winding with soaking varnish.

The distance profiles with an "X-shaped cross section" increase by the enlargement of the Air chambers as well as the two additional Air chambers the chimney effect.

By using thermoplastic materials with a lower specific weight and the lower material content of the Both profiles achieve a material and weight saving.

In addition, there is no waste because the Profiles in fixed lengths to be produced.

Unlike the thermoset, glass fiber reinforced Polyester profiles are the described thermoplastic “M + X Profiles "can be recycled Dust pollution by cutting and thus prevents dust allergies. The frequent so far Injuries caused by long unbound glass fibers are completely eliminated.

So far, coil carriers are plug-in elements known by T-shaped Recesses in the corner pieces with the T-shaped counterparts the connector or extension pieces vertical knocked into each other.

There are openings in the corner pieces for holding corner profiles made of thermosetting, glass fiber reinforced polyester are (Fig. I.II) and these are precisely adapted for independent clamping to achieve by hammering.

Through burr formation and positive tolerance the corner profiles have often been destroyed when cornering. The Connecting with the connecting and extension pieces required something manual Skill.

The sharp-edged T-groove-shaped recess in the corner pieces led on the one hand to the assembly due to inaccurate placement before hammering or during the winding process on the coil cage due to mechanical stress to break out the corner pieces.

The corner pieces have 2 T-shaped recesses and the extension pieces 1 T-shaped as well a T-shaped counterpart on. The extensions and connectors are straight strip-shaped Rectangular cross-section parts. The straight strip-shaped connecting parts close a large part of the ventilation opening between the finished coil Iron core and winding and will be back after completion removed (obstruction of the chimney effect).

The corner pieces have a longitudinal groove for receiving the spacer strips, so-called "Dogbone" image I.III, which are also made of thermosetting, glass fiber reinforced polyester are between primary and secondary winding. The insertion opening is sharp-edged.

The outer contour of the corner piece is formed by straight lines that meet at different angles. A straight line ends exactly opposite the Tnutförmigen Recesses. These opposite Corners form a preprogrammed breaking point even at a small one mechanical stress.
