Embodiment 1

[0016] In the actual product, the copper clad laminate can use PCB rigid circuit board or FPC flexible circuit board.

[0017] Embodiment two:

[0018] First, design the mechanical specifications of the film coil according to the technical requirements, including appearance, size, coil line width, coil line pitch, coil number, coil layer number, coil welding points, and then on the metal foil, use etching, wire cutting, The method of stamping forming forms a layered planar coil (as shown in Figure 2).

Embodiment 2

[0020] Embodiment three:

[0021] First, design the mechanical specifications of the thin film coil according to the technical requirements, including shape, size, coil line width, coil line distance, insulating material, insulating material thickness, number of coil turns, number of coil layers, coil welding points, coil thickness, and then On the outside of a reel, metal foil and insulating film (as shown in Figure 3) are wound according to the design to form a multi-layer barrel structure with metal foil and insulating film spaced apart from each other. In FIG. 3 , 3.1 is the reel, 3.2 is the metal foil, and 3.3 is the insulating film.

Embodiment 3

[0023] Embodiment four:

[0024] First, according to the mechanical structure designed by the wireless charger, design the mechanical specifications of the flexible flat cable for electrical connection, including the length, the width of the connecting metal wire, whether it needs to be folded and how to fold it, and then make the flexible flat cable according to the design . Finally, the transmitting coil and the wireless charging drive control board are electrically connected with the fabricated flexible flat cable by welding and plugging (as shown in Figure 5).

Abstract

The invention provides wireless charger equipment with low cost. The wireless charger equipment is characterized in that a wireless charger uses a low-cost wireless charger transmitting coil (5.1) manufactured by a printed circuit board, an etching metal foil or a narrow band metal belt; and the transmitting coil is connected with a wireless charge control driving circuit board (5.3) by using a low-cost flexible and flat cable (5.2), so that the characteristics of high frequency and large current can be satisfied, and the cost can be reduced.

Description

technical field [0001] The invention relates to a wireless charger device using a novel wireless energy transmitting coil and a novel connecting wire. Background technique [0002] Wireless chargers have become popular in recent years and are used to charge mobile phones, tablet computers and other devices. Compared with wired chargers, which require wiring, it is more convenient. However, including the Qi standard published by the International Wireless Charging Consortium WPC, the current production of the transmitter coil of the charger is made of enameled wire and silk-covered wire materials, and is manufactured through a winding process. Although the above processing method is simple and easy to put into production, it has many disadvantages: difficult production, low efficiency, high cost, high thickness, manual welding is required, and it is difficult to change the length of the lead wire. In this way, it is very unfavorable for the price reduction, market promotion ...
