Example 1
As shown in fig. 2, a network transformer using three-stranded wires includes a case 10 and a PIN unit 20 disposed on the case 10, specifically, in this embodiment, SMD16PIN is taken as an example; two sets of windings are provided inside the housing 10, each set comprising a first magnet unit 70 and a second magnet unit 80, both of which are substantially identical in structure,
the first magnetic unit 70 is wound with the first winding unit 40 and the second winding unit 50; one first magnetic unit 70 corresponds to one stranded wire unit 60, one end of the stranded wire unit 60 and one end of the second wire wrapping unit 50 extending out of the first magnetic unit 70 are stranded to form a first stranded unit 62, the other end of the stranded wire unit 60 and the other end of the second wire wrapping unit 50 extending out of the first magnetic unit 70 are stranded to form a second stranded unit 63, the first stranded unit 62 is connected with a hollow PIN 61 in the PIN unit 20, and the second stranded unit 63 is connected with the PIN unit 20 after being wound around the second magnetic unit 80.
In particular, as shown in fig. 3-6, the first winding unit 40 comprises a first winding singlet 41 and a second winding singlet 42, both the first winding singlet 41 and the second winding singlet 42 being wound on a first magnetic unit 70; the head end of the first winding single piece 41 is arranged on the pin unit 20, the tail end of the second winding single piece 42 is arranged on the pin unit 20, and the tail end of the first winding single piece 41 and the head end of the second winding single piece 42 are arranged on the pin unit 20 in a twisted mode; the second winding unit 50 comprises a third winding single piece 51 and a fourth winding single piece 52, the stranding unit 60 is a fifth winding single piece, the third winding single piece 51 and the fourth winding single piece 52 are wound on the first magnetism, and the head end of the third winding single piece 51, the tail end of the fourth winding single piece 52 and the head end of the fifth winding single piece are wound on the second magnetism unit 80 after being stranded; the tail end of the third winding strand, the head end of the fourth winding strand 52 and the tail end of the fifth winding strand are twisted and arranged at the empty PIN 61 of the PIN unit 20.
Since the SMD16PIN generally has only 16PIN legs, in the first group of winding magnets, the first winding unit 40 occupies 3 PIN legs, and the second winding unit 50 occupies 3 PIN legs; in the second group of winding magnets, the first winding unit 40 occupies 3 PIN feet, and the second winding unit 50 occupies 3 PIN feet; that is to say, the original design standard of the small network transformer has more empty PIN PINs for connecting the stranded wire unit 60; if multiple sets of windings are provided, there is also a surplus of empty PIN legs for use.
For the SMD16PIN network transformer having such a structure, there is more sufficient space for placing the first and second magnetic units 70 and 80, and at the same time, the first and second winding units 40 and 50 can be wound more tightly while increasing the number of winding turns, reducing the cost and process steps, and improving the production efficiency.
In addition, the connection mode of the first twisted unit 62 and the empty PIN 61 in the PIN unit 20 is as follows: winding and then plating tin; here the winding is mainly a manual operation or a machine operation, and if tinning is carried out, the PIN PINs need to be tinned by utilizing the method, and no additional process step is needed.
Moreover, first kinking unit 40, second kinking unit 50 and stranded conductor unit 60 adopt the enameled wire of the same material to constitute, and simultaneously, the colour of the enameled wire that first kinking unit 40, second kinking unit 50 and stranded conductor unit 60 adopted is different, is convenient for distinguish and dodges, adopts red, blue, gold, trichrome.
Of course, the above setting is not limited only.
By analogy, other different strands may be provided, not necessarily in this embodiment.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
