Description

Technical Field

[0001] The utility model relates to the technical field of transformer inductance assembly, in particular to an assembly positioning tool for transformer inductance. Background Art

[0002] Conventional RM5 inductors consist of two upper and lower magnetic cores 5, an inductor coil 6 and a retaining spring 7. The coil 6 is located between the upper and lower magnetic cores 5, and the upper and lower magnetic cores 5 are clamped by two retaining springs 7. At present, the assembly of RM5 inductors usually adopts manual picking, assembly and placement of parts, and only one RM5 inductor can be assembled each time, which is time-consuming and labor-intensive, and the assembly efficiency is low. This is because the magnetic core 5 is of a special shape, and the assembly gap between the magnetic core 5 and the coil 6 is small. During assembly, the positions of the upper and lower magnetic cores 5 are not easy to align, and there is a problem of misalignment, which requires manual adjustment and correction. However, in the process of correcting the position, fingers are easy to touch the lower pin 6a of the coil 6, causing the pin 6a to deform and the assembly quality to be low. How to solve the high-efficiency and high-quality assembly of inductors has long been a difficult problem to solve. Summary of the invention

[0005] A transformer inductor assembly positioning tool comprises a long strip tool with a rectangular cross-section, wherein a plurality of positioning grooves for two magnetic cores with notches facing upward are arranged at the upper end of the long strip tool, and each positioning groove is square in shape, and the first diagonal corner of the square is located on the longitudinal center axis of the long strip tool, and a clearance hole penetrating the long strip tool along the groove depth is arranged at the first diagonal corner, which is used to make way for the pins of the wire package, and the second diagonal corner of the square is located on the lateral sides of the long strip tool, and the lateral side walls of the long strip tool are provided with openings extending along the groove depth, and the openings are located at the second diagonal corners of the square, and the lower end of the opening is provided with a clearance groove for making way for the spring pin of the spring.

[0006] The slot width of the positioning slot is 0.1 mm to 0.2 mm greater than the distance between the symmetrical sides of the magnetic core.

[0007] The transverse width of the clearance hole along the long strip tooling is greater than the longitudinal width of the opening along the long strip tooling.

[0008] The longitudinal width of the opening along the long strip of tooling is greater than the longitudinal width of the clearance groove along the long strip of tooling.

[0009] The depth of the positioning groove is greater than or equal to the height of the two magnetic cores after the inductor is assembled.

[0010] The long strip tooling is made of glass fiber board.

[0011] The beneficial effects of the utility model are as follows: by adopting the long strip tooling of the utility model, the upper and lower magnetic cores are positioned through the positioning grooves, so that the upper and lower magnetic cores are prevented from being misaligned, thereby improving the assembly quality; and a plurality of positioning grooves are arranged on the long strip tooling, so that the operator can assemble multiple products at the same time, thereby improving the assembly efficiency.
