Embodiment Construction

[0015] Reference attached Figure 1-2 , a double outer lead terminal coil, which is composed of M×N wire turns; both lead terminals 1 are located on the outermost layer at one end of the entire coil, and it is characterized in that the inner wire turns of the coil have the following structure Winding; the starting wire starts from the outermost layer on the side of the two lead terminals 1, and wraps a single wire M circles from outside to inside to the smallest wire circle to form the end bezel part 2, and then arranges layers horizontally and winds N-1 circles; The wire at the position of the N-1 lap wraps one lap and enters the M-1 layer. This layer is arranged in a total of N-1 laps and meets the end bezel part 2, and then laps and enters the M-2 layer. Reversely rewind again; reciprocate in this way until the first layer rewinds N-0.5 circles to reach the starting position of the end bezel part 2 to form the body bezel part 3;

[0016] The M is an even number greater tha...

Abstract

The invention relates to a double external lead terminal coil and a winding method, which are formed by stacking and combining M * N conductor turns; A loop inside that coil is provide with an end gauge ring portion and a body re portion; The winding method comprises the following steps: firstly, drawing out the conductor with the length equal to M turns as the reserve end; At one end of the coilmold, the M-length position of the wire is started to be wound; The wire supply coil end is arranged in the forward direction around one layer, and the wire reserve end is wound in the reverse direction around one circle. This reciprocates to form a complete double external lead terminal coil. The invention is innovative in that: a complete double external lead terminal coil is skillfully assembled by using different end bezel portions and body bezel portions of a winding structure; The characteristics of the double external lead terminals of the coil are realized.

Description

technical field [0001] The invention relates to a new coil winding structure, in particular to a double outer lead terminal coil and a winding method. Background technique [0002] With the development of science and technology, the application fields of coils are becoming more and more extensive. Coils are widely used in common mode filters, multi-frequency transformers, impedance transformers, balanced and unbalanced conversion transformers, EMI noise suppression of electronic equipment, personal computers and USB lines of peripheral equipment, liquid crystal display panels, low-voltage differential signals, car remote control keys, wireless charging equipment, etc. Coils are developing in the direction of miniaturization and low power consumption, requiring the volume of coils to be smaller and smaller to meet different application requirements. However, the current coil winding method is difficult to meet the requirements for coil size and electromagnetic characteristic...
