Detailed Description

The following describes the present invention in further detail with reference to the accompanying drawings.

Network transformer packing part, main part 1 made including insulating material, the main part is by the open-ended chamber 3 that holds up and be located the base 2 that holds the chamber bottom and constitute, a pair of parallel lateral wall top that holds chamber 3 has two rows of first pilot holes 4 that the array was arranged, base bottom surface edge have two rows with the second pilot hole that first pilot hole projection position corresponds, corresponding position have between first pilot hole and the second pilot hole and run through hold the through-hole of chamber lateral wall and base.

The utility model discloses mainly be for the convenience welded fastening network transformer subassembly on PCB or other circuit boards, during the equipment, insert first pilot hole and second pilot hole with metal contact pin earlier, the length of metal contact pin equals the interval between the two, as shown in fig. 2, after accomplishing the coil winding of network transformer, with the head line and the tail wire spot welding of coil on the metal pad in first pilot hole, then will be equipped with transformer coil's main part and place the welding position on the PCB board, with the corresponding solder joint of metal pin foot welding on the second pilot hole on the PCB board. The insulating material can be LCP plastic (liquid crystal POLYMER). In the embodiment shown in fig. 2, the internal components consisting of the transformer coil 8, and the filter coil 9, the taps of the wires 10 are soldered to the first mounting holes.

One preferred embodiment is: the edge below the base is provided with a wiring board 7 which is parallel to the arrangement direction of the second assembly holes and is perpendicular to the base, and the wiring board is provided with a transverse wiring hole 5 corresponding to the second assembly hole.
