Description
Technical Field
The utility model relates to a buzzer, especially high temperature resistant buzzer.
Background
The buzzer comprises a plastic shell, a buzzer piece and a pin, wherein the pin is usually fixed on the plastic shell through an adhesive, and the buzzer piece is connected with the plastic shell through the adhesive in order to improve the installation firmness. The disadvantages of the above structure are: it is not suitable for high temperature application, because once the high temperature air contacts the adhesive, the adhesive can be cracked and the like, and finally the stitch or the buzzer chip can be loosened.
Disclosure of Invention
To the not enough of prior art, the utility model provides a high temperature resistant buzzer.
The technical scheme of the utility model is that:
high temperature resistant bee calling organ, it includes plastic housing, buzzing piece and stitch, its characterized in that:
the plastic shell is provided with three support lugs, and each support lug is provided with a convex slot which penetrates through the support lug up and down;
the buzzer comprises a steel sheet and a piezoelectric ceramic sheet arranged on the steel sheet;
the pin comprises an inserting piece, an elastic piece, a straight rod and a curved rod, wherein the elastic piece protruding out of one side face of the inserting piece is arranged in the center of the inserting piece, the inserting piece is inserted into the convex-shaped slot, the straight rod is vertically connected to the upper end of the inserting piece, and the curved rod is connected to one side, far away from the straight rod, of the top face of the inserting piece;
the curved bar of one pin is welded with the steel sheet on the buzzer sheet through the welding flux, the other curved bar is welded with the piezoelectric ceramic sheet on the buzzer sheet through the welding flux, the curved bar of the other pin is not contacted with the buzzer sheet, and the pin only plays a balance role and is not electrically connected.
Furthermore, the support lugs are arranged at equal intervals, so that the balance of the whole device is guaranteed.
Furthermore, the inserting sheet, the elastic sheet, the straight bar and the curved bar of the pin are formed by punching the same metal sheet, so that the connection strength and the electric connection of the inserting sheet, the elastic sheet, the straight bar and the curved bar are ensured.
Furthermore, the plastic shell is formed by injection molding of flame-retardant plastic, and has a high-temperature resistant effect.
The utility model has the advantages that: the pins are fixed on the plastic shell through the unique structure of the pins, adhesive is not needed to participate in fixation, and the pin fixing structure is suitable for being used in high-temperature and large-temperature-difference environments. In addition, the buzzer is pressed in the plastic shell by the curved rod of the pin, and the use of an adhesive is reduced or avoided.
