Abstract

The invention discloses a novel buzzer guide pin. The novel buzzer guide pin comprises a guide pin body, the guide pin body comprises a guide pin end portion, a guide pin body portion, and a guide pin head portion, the guide pin body portion is arranged at the central portion of the guide pin body, a side surface of the guide pin body portion is provided with at least a ring of groove whose cross section is in a semicircular shape, the guide pin end portion is welded with a blade, and the guide pin head portion is welded with a contact piece. According to the novel buzzer guide pin, the structure is simple, the welding is facilitated, the welding firmness is good, and the burnout of a circuit board can be prevented; besides, the strength of the guide pin body is high, the fracture is avoided, and the service lifetime is long.

Description

technical field [0001] The invention relates to the technical field of buzzers, in particular to a novel buzzer guide pin. Background technique [0002] The existing structure of the buzzer is that a buzzer piece is arranged in the buzzer shell, and two guide pins are installed under the buzzer piece, wherein the guide pins are generally in a T-shaped structure, and the T-shaped guide pins are fixed by welding with an electric soldering iron. circuit board. When making a buzzer, since the T-shaped guide pin needs to be welded on the circuit board by an electric soldering iron, and the circuit board is thin, the high-temperature solder is easy to burn, and the stability of the guide pin welded on the circuit board is poor; The buzzer guide pin in the prior art has low strength, is easy to break, and has a short service life. Contents of the invention [0003] The purpose of the present invention is to provide a new type of buzzer guide pin to solve the problems raised in ...
