Description

Technical Field

[0001] The utility model relates to the technical field of pins, in particular to a pin of a bridge rectifier KBL. Background Art

[0002] A bridge rectifier is made of four rectifier silicon chips connected in a bridge manner and encapsulated with insulating plastic. A high-power bridge rectifier is encapsulated with a zinc metal shell outside the insulating layer to enhance heat dissipation. Pins, also known as tube pins, are the wiring from the internal circuit of the integrated circuit (chip) to the peripheral circuit. All pins constitute the interface of this chip. A section at the end of the lead is soldered to form a solder joint with the pad on the printed circuit board. The pins can be divided into heel, toe, and side of the foot. The pickled chip pins in the bridge rectifier are generally not equipped with protective devices. They are easily corroded by the external environment during use, and the anti-electromagnetic shielding effect is poor. They are easily affected by electromagnetic interference, which affects the use effect. Therefore, a pin of a bridge rectifier KBL is proposed to solve the above problems. Utility Model Content
