Non-contact power supply transformer

Abstract

A coil main body is provided with: magnetic pole core members (141, 142) constituting a pair of parallel magnetic pole parts; a winding core member which intersects with the magnetic pole core members (141, 142) and which connects a portion of the pair of parallel magnetic pole core members (141, 142); and a wire (150) wound around the winding core member. A non-contact power supply transformer in which the coil main body is secured to a secure plate (160) exhibiting a magnetic shielding function and a heat-releasing function, wherein: the location at which the winding core member connects to the magnetic pole core members (141, 142) slants towards one direction from the center of the magnetic pole core members (141, 142) in the length-wise direction; and a space that is sandwiched by the pair of magnetic pole core members (141, 142) and that includes an edge part of which the distance to the connection position is longer is used as a space (70) for arranging components which electrically connect to the wire (150). The burden of wiring work is reduced during installation because the coil main body and the components electrically connected thereto are stored in the non-contact power supply transformer.

Description

technical field [0001] The present invention relates to a power supply transformer of a non-contact power supply system for supplying power to electric vehicles and the like in a non-contact manner, and an electric component connected to the power supply transformer, which facilitates installation of the transformer on vehicles and the like. Background technique [0002] As an example of a system for charging batteries of electric vehicles and plug-in hybrid cars, such as Figure 8 As shown, a secondary side transformer (receiving transformer) 33 of the power supply transformer 30 of the non-contact power supply system has been developed on the floor of the vehicle, and the primary side transformer (power transmission transformer) 31 installed on the ground side uses power. Magnetic induction is a method of supplying power in a non-contact manner. [0003] A plug-in hybrid vehicle that is charged has an engine 54 and a motor 53 as drive sources, a secondary battery 51 as a p...

Problems solved by technology

[0016] However, in this non-contact power supply transformer, with respect to the electric wire 50 drawn out from the lead-in hole 61 of the fixing plate 60, in the case of a product for vehicle installation, such as Figure 8 shown must be electrically connected to the secondary side parallel resonant capacitor 34, rectifier 35

In addition, in the case of products for installation on the ground, it is necessary to electrically connect the primary side series capacitor 32

Therefore, there is an increase in the work load when installing the transformer and the need to secure wiring space.
