Embodiment Construction

[0048] For example Figure 1 to Figure 4 As shown, the flat coil 1 has a coil wire 2 extending in a helical and flat manner, which is accommodated in a carrier 3 of the flat coil 1 , which is also referred to below as the flat coil carrier 3 . The flat coil carrier 3 has a carrier body 4 which is formed in a plate-like manner. The carrier body 4 extends in a plane substantially perpendicular to the axial direction 5 . To accommodate the coil wire 2 , the carrier body 4 has a groove spiral 7 on the axial front side 6 , which extends helically in line with the course of the coil wire 2 . The groove spiral 7 thus extends on the carrier body 4 transversely to the axial direction 5 . The groove spiral 7 thus has an axially open groove opening 8 . Due to the helical course of the groove spiral 7 , the groove spiral 7 has radially continuous groove sections 9 , wherein the respective groove section 9 each has or forms a part of the groove opening 8 , wherein this part is also refe...

Abstract

The invention relates to a flat coil carrier (3) for a flat coil (1), comprising a carrier body (4), which comprises helically extending groove spirals (7) for receiving coil wires (2) of the flat coil (1). According to the invention, simplified assembly of the flat coil (1) and / or simplified use of the flat coil (1) in corresponding applications and increased precision are achieved by providing projections (13) in at least some regions of the groove screw (7), said projections forming undercuts (14) of the coil wire (2). The invention also relates to a method and an injection molding tool (30) for producing a flat coil carrier (3) of this type. The invention further relates to a flat coil (1) comprising a flat coil carrier (3) of this type.

Description

technical field [0001] The invention relates to a flat coil carrier comprising a carrier body with a helically extending groove helix for receiving a coil wire of the flat coil. The invention also relates to a flat coil of this type. Furthermore, the invention relates to a method for producing a flat coil carrier of this type by injection molding and an injection molding tool for producing a coil carrier of this type. Background technique [0002] Flat coils have coil windings extending helically in essentially one plane. The coil winding usually consists of coil wire which is accommodated in a coil carrier of a flat coil. This type of flat coil can be used for any purpose. Flat coils of this type are used in particular as high-performance flat coils for responding to inductive charging of electrical energy carriers, eg in motor vehicles. [0003] The use of a flat coil of this type in an inductive charging device for a motor vehicle is known from DE 10 2017 207 266 A1. ...
