Problems solved by technology

Therefore, in this case, even moderately thick wires cannot scatter the glass fibers
[0006] With this method, the wire cannot reliably spread out the glass fibers if the wire is too thin or if the insulation is too dense during application

[0031] refer to Figures 1a to 1c , a first embodiment of the conductor handling tool will be described. exist Figures 1a to 1c , in the y direction ( Figure 1a ), from the x direction ( Figure 1b ) and from the z direction ( Figure 1c ) shows the conductor handling tool in the corresponding side view. In addition, the corresponding directions x, y and z are marked in the respective figures. These directions are orthogonal with respect to each other.

[0032] The conductor handling tool has a tool body 10, a conductor receiving opening 20 (formed as a slot 26 with two open ends 22, 24) and a tapered cutting edge 12 extending in a plane. The above directions x, y and z are defined such that the plane in which the blade 12 extends is the y-z plane.

[0033] Tool body 10

[0034] The tool body 10 is shaped as a plate whose extension in one direction (x-direction) is smaller than its extension in the other directions (y-direction and z-direction). The plate has a se...

[0062] Figures 3a to 3c A second embodiment of the conductor handling tool is shown in a corresponding side view from the y, x and z directions, respectively. Figure 3a and 3c corresponds to Figures 1a to 1c , and the same or similar elements are denoted by the same reference numerals. Hereinafter, only relative to the first embodiment ( Figures 1a to 1c ) difference.

[0064] The conductor receiving opening or slot 28 is form-fit to the shape of the coil lug for receiving the coil lug therein. Here, "form fit" means that the slot 28 is sized so that the main part of the sheet can be inserted therein, and that the slot 28 fits the contour of the sheet so that the inserted part is held in the slot by the shape of the slot 28 .

[0069] according to Figure 4a , 4b In another general aspect shown in and 5, the conductor handling tool may further include conductor securing means adapted to cooperate with the conductor receiving opening to secure a conductor received in the conductor receiving opening. The conductor securing means can be, for example, a cover, a cover or an elastic element.

Abstract

A conductor handling tool has a plate-shaped tool body (10). The tool body (10) comprises a conductor receiving opening (20) for receiving a conductor portion therein and for holding the conductor portion received therein. Further, an edge of the plate-shaped tool body is shaped convex as a tapered blade edge (12) extending essentially within a y-z-plane. The tapered blade edge (12) is directed away from the conductor receiving opening (20) and is forming an outer circumferential portion of the tool body (10) for splitting a portion of insulating material during winding of the insulating material.

Description

technical field [0001] Aspects of the invention generally relate to methods of applying an electrically insulating material to at least a portion of an electrical device, such as an electrical coil, and to conductor handling tools. Background technique [0002] Often, many electrical devices need to be insulated in such a way that only a few defined conductors are accessible from the outside. For example, a transformer coil needs to be insulated, but it also needs to have connectors that allow external connections at specific locations within the coil. [0003] A suitable insulating material for insulating the electrical device may be, for example, a composite material made of glass fibers and resin. The insulating material is usually wound on the coil by rotating the coil. Connectors are provided by the ends or mid-sections of the wires. Connectors need to go through insulation. This is usually accomplished by manually guiding these wire ends or intermediate portions th...
