Thus improve production efficiency, quality controllability and product reliability, reduce production cost and product fraction defective.
Refer to Fig. 4 to Fig. 6, the embodiment of the present invention also provide a kind of SMD transformer, comprising:
Ring transformer 3, and the purchasing ore of ring transformer as mentioned in Fig. 1 to Fig. 3 embodiment;
The hollow body 1 that ring transformer 3 is arranged on the purchasing ore of ring transformer 3 is inner, and the winding wire 31 of ring transformer 3 is connected with the wire pin terminal 21 that twines on hollow body 1, it will be appreciated that aforesaid ring transformer 3 can be magnetic ring transformer.
The SMD transformer of the embodiment one of Fig. 4 comprises the purchasing ore of ring transformer 3 and ring transformer, and the purchasing ore of ring transformer 3 is made up of hollow body 1 and pin terminals 2, and ring transformer 3 is placed in hollow body 1. The SMD transformer of the present embodiment is the transformer device structure that two groups of pin terminals 2 all adopt, and two groups of pin terminals 2 are distributed in the left and right sides of hollow body 1, and every side is evenly distributed 6 pin terminals 2. Wherein twining wire pin terminal 21 and in hollow body 1 upper end and be perpendicular to hollow body 1 bottom surface, paster pin terminals 22 is at hollow body 1 time end and is parallel to hollow body 1 bottom surface.
The present embodiment can realize the SMD transformer of four winding wires 31, and each winding wire 31 has 3 the end of a thread 32, completely isolated between two, left side winding wire 31 and two, the right winding wire 31. Spacing (7mm) design of the two groups of pin terminals 2 in left and right is enough big, and the isolation that at least can bear more than 6KV is withstand voltage. Therefore, this SMD transformer may be used for the withstand voltage following power supply module product of 6KV isolation. After SMD transformer solidifies as super little microencapsulated device, can by the turn ratio of testing of equipment transformer and other unit for electrical property parameters before paster uses. Thus improve production efficiency, quality controllability and product reliability, reduce production cost and product fraction defective, the paster pin terminals 22 of bottom surface is sleeping mounted surface patch pin terminals, takies pcb board area than the SMD transformer of traditional sea-gull pin design less.
The advantage of the SMD transformer in the present embodiment:
(1) volume is less, and super little miniatureization paster encapsulates;
(2) planeness is better. Transformer twines wire pin terminal 21 and paster pin terminals 22 in the different position of different pin terminals 2, twines wire pin terminal 21 and soaks tin more convenient operation, can not affect the planeness of paster pin terminals 22. Whole face of weld is exactly IC welding process.
(3) twining the card groove structure design of wire pin terminal 21 so that it is more convenient that transformer twines line, it is more firm to connect.
The embodiment of the present invention also provides a kind of SMD transformer manufacturing process, comprising:
Step one: the hollow body of the purchasing ore that the ring transformer of good for coiling coiling group is put into ring transformer is inner;
Step 2: the lead-in wire of coiling group is wrapped in respectively according to preset function and twines on wire pin terminal on hollow body;
Step 3: the ring transformer after paint removal being processed is cured;
Step 4: fill hollow body interior space by colloid, colloid herein is such as silica gel, specifically do not limit herein, simultaneously, this step 4 can be determine whether as required to perform in SMD transformer manufacturing process, and it is known to the skilled person technology, just repeat no more herein.
Concrete, for the SMD transformer of embodiment one correspondence, the transformer that coiling is good is put in hollow body 1, the lead-in wire of transformer is divided according to function, it is wrapped in twining on wire pin terminal 21 terminal of hollow body 1 respectively, makes winding wire 31 and twine wire pin terminal 21 termination contact. Each twines wire pin terminal 21 terminal can be wound around 1��2 enameled wire. Then by wind twine wire pin terminal 21 terminal leaching tin remove wire enamel layer so that transformer winding wire 31 with twine wire pin terminal 21 terminal conducting. Again by magnetic core of transformer and winding wire 31 polish solidifications, finally fill transformer casing Base internal space with colloid, the magnetic core of whole transformer and winding wire 31 embedding are got up, quakeproof moisture-proof, strengthen insulation characterisitic. The SMD transformer of super little miniatureization has just completed.
The above, above embodiment only in order to the technical scheme of the present invention to be described, is not intended to limit; Although with reference to previous embodiment to invention has been detailed description, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or wherein part technology feature is carried out equivalent replacement; And these amendments or replacement, do not make the spirit and scope of the essence disengaging various embodiments of the present invention technical scheme of appropriate technical solution.
