Description

Technical Field

[0001] The utility model relates to the field of inductors, in particular to a three-pin inductor with pins arranged in an inline pattern and a braided tape thereof. Background Art

[0002] The pins of traditional three-pin inductors are distributed in an equilateral or isosceles triangle. Due to the traditional three-pin inductor pin distribution, when the inductor is packaged with tape, when two of the pins are distributed on the tape, the remaining pin is in a non-planar relationship with the tape. It is difficult to fix three pins at the same time with the tape, and the inductor pins are difficult to fix after packaging. The tape needs to be additionally provided with slots for accommodating pins. The tape uses more materials, which is not conducive to cost control. Because the pin holes of the traditional three-pin inductor core are arranged in a triangle, many production processes cannot be produced by automated equipment.

[0003] Therefore, a three-pin inductor and a braid are proposed, wherein each pin is packaged separately and wrapped on the braid during packaging. Utility Model Content

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a three-pin inductor with pins arranged in a line and a braid thereof, wherein the inductor comprises an inductor body and a pin group, the cross-section of the inductor body is circular, the pin group comprises three pins, the three pins are arranged at intervals on the end surface of the inductor body, the three pins are arranged parallel to each other, and the center lines of the three pins are arranged in the same plane.

[0005] It also includes two inductors, and the three pins include a starting pin, a common pin and a terminal pin arranged in sequence along a straight line, one of the inductors connects the starting pin and the common pin, and the other inductor connects the common pin and the terminal pin.

[0006] Preferably, the pin comprises a pin body and a pin end, the pin body and the pin end are both cylinders, and the pin end is integrally formed and connected with the pin body.

[0007] A braid comprises a braid and a plurality of three-pin inductors with pins arranged in a line, wherein the inductor body is evenly spaced and arranged on one side of the braid, and the pin group is arranged on the braid.

[0008] Preferably, a protective film is further included, wherein the protective film is fixedly arranged on the braid, and the pin end is fixedly arranged between the braid and the protective film.

[0009] Preferably, a bonding area is provided in the middle of the braid, and the protective film is arranged in the bonding area.

[0010] Preferably, the inductor bodies are evenly spaced and arranged on both sides of the braid, and the pin groups are staggered and arranged on the braid.

[0011] Preferably, the braid and the protective film are evenly spaced apart to form a plurality of semicircular grooves, and the end of the pin is disposed between two of the semicircular grooves.

[0012] The beneficial effects of the utility model are as follows: the inductor body is circular, and the three pins of the inductor are distributed along a straight line on the end surface of the inductor body, which can fully improve the utilization space of the winding and facilitate the winding.

[0013] The center lines of the three pins of the inductor are distributed in the same plane. When the inductor is packaged by taping, the three pins of the inductor can be placed on the tape at the same time, and the protective film is covered to fix each pin, which can fix each pin and provide protection for each pin. It can be taped automatically and the pins can be inserted automatically. BRIEF DESCRIPTION OF THE DRAWINGS
