Description

Hairpin type flat wire inductor Technical Field The utility model relates to the technical field of flat wire inductors, in particular to a hairpin type flat wire inductor. Background Hairpin flat wire inductors are a special type of inductor that is commonly used in high frequency applications and has high efficiency and small size. Such an inductor is named for its unique shape, and its pins are bent into a hairpin-like form, so that the wire assumes a flat structure. Such a design helps to improve heat dissipation, reduce parasitic capacitance, and can achieve higher inductance values in a limited space. When the conventional flat wire inductor is used, the length of the pins is very long for facilitating connection of the pins, and the connection part is not provided with any protection mechanism, so that the pins are easy to bend and damage when in use, and the effect of protecting the pins is not achieved. Disclosure of utility model The utility model aims to provide a hairpin type flat wire inductor, which solves the problem that the existing flat wire inductor pins proposed in the background art are not protected during use, so that damage is easy to occur. The hairpin flat wire inductor comprises a magnetic core and pins, wherein a coil is wound on the outer side of the magnetic core, a packaging shell is arranged on one side of the magnetic core, and the pins are connected to one end of the coil; The outside of pin has cup jointed the protection piece, the both sides of protection piece all are connected with the fixed block, the inserted block is installed at the top of fixed block. Preferably, one side of the insert block is connected with a rotating block through a rotating shaft, and a movable spring is connected between the rotating block and a groove of the insert block. Preferably, a movable block is arranged on one side of the rotating block, and a pushing block penetrates through the packaging shell on one side of the movable block to be connected with the packaging shell. Preferably, a bump is mounted at one end of the package housing, and a telescopic spring is mounted inside the bump. Preferably, a wedge block is installed on one side of the telescopic spring through the lug, and a clamping ring is sleeved at one end of the wedge block. Preferably, a pressing block is arranged in the clamping ring through a groove, and one end of the pressing block is connected with a pull rod penetrating through the clamping ring. Preferably, the wedge block and one end of the pressing block, which are close to each other, are of inclined structures, and the wedge block forms a telescopic structure with the protruding block through a telescopic spring. Compared with the prior art, the hairpin type flat wire inductor has the beneficial effects that when the hairpin type flat wire inductor is used, the protection block can be sleeved on the outer side of the pin according to the use requirement of the pin, so that the fixed blocks on two sides of the protection block drive the plug block to be inserted into the groove of the packaging shell, in the process of inserting the plug block, the rotary block can be contracted into the groove of the plug block, when the plug block is completely inserted into the packaging shell, the rotary block can reversely reset and rotate through the movable spring, and the protection block can be stably sleeved on the outer side of the pin through the rotary block and the plug block, thereby playing a role in reinforcing and protecting the pin. 1.
