Abstract

The utility model discloses a AI plug -in components formula buzzer of square pin, including face -piece and drain pan, be equipped with the buzzing piece in the space that face -piece and drain pan constitute, be equipped with two guide pins below the buzzing piece, the guide pin includes elasticity arm and guide pin pin, and the elasticity arm passes through sheet metal type guide pin shell fragment to be connected with the guide pin pin, and the guide pin pin passes the drain pan and extends to the drain pan outside, and the cross -section of guide pin pin is squarely. Through the design of square guide pin pin, reduce the pressure influence that the guide pin shell fragment produced to the buzzing piece, and even can ignore to the pin is cuted stably, is convenient for cut off.

Description

A kind of AI plug-in type buzzer of square pin

Technical field

This utility model relates to a kind of buzzer, particularly to the AI plug-in type buzzer of a kind of square pin.

Background technology

Thin plate pin its pin of braid buzzer the most on the market uses thickness metallic conductor guide pin within 0.20mm to set mostly , there is guide pin pin insufficient rigidity in meter, user exists pin when carrying out automatism card machine plug-in unit and is difficult to the defects such as cut-out；And Using thickness to design at the metallic conductor guide pin of more than 0.20mm (or diameter is at 0.2mm), its guide pin elastic force is more than piezo Tension force, tension variation is the important leading factor of resonant frequency of buzzer, directly result in buzzer electrical property consistency be deteriorated, Quality controllable degree declines to a great extent.

A kind of solution is such as the patent of publication number CN 203165449 U, it is provided that a kind of buzzer, its guide pin passes through thin plate Type guide pin shell fragment is connected with piezo, but its (and other in prior art) guide pin pin is circle, and circular The defects such as it is excessive that guide pin exists elastic force, and then is easily caused the poor electrical performance of buzzer, and pin shearing is unstable.

Drawbacks described above, is worth improving.

Summary of the invention

In order to overcome the deficiency of existing technology, this utility model provides the AI plug-in type buzzer of a kind of square pin.

Technical solutions of the utility model are as described below:

A kind of AI plug-in type buzzer of square pin, the space constituted including face-piece and drain pan, described face-piece and described drain pan Inside being provided with piezo, described piezo is arranged below two guide pins, it is characterised in that described guide pin includes elasticity arm and guide pin Pin, described elasticity arm is connected with described guide pin pin by sheet-type guide pin shell fragment, and described guide pin pin passes described drain pan And extending to outside described drain pan, the cross section of described guide pin pin is square.

Further, described sheet-type guide pin shell fragment is connected with the welding of described guide pin pin or riveted.

Further, the thickness of described guide pin pin is 0.30mm-0.60mm.

Further, the thickness of described elasticity arm is less than 0.28mm.

Further, it is provided with guide pin contact on the downside of the top of described elasticity arm.

Further, described face-piece and described drain pan clamping.

Further, described drain pan is provided with the groove accommodating described sheet-type guide pin shell fragment.

According to this utility model of such scheme, it has the beneficial effects that, this utility model overcomes that round guide pin elastic force is excessive leads Cause the defect of buzzer electrical property consistency difference, designed by the square lead pin that thickness is 0.30mm-0.60mm, reduce The pressure influence that piezo is produced by guide pin shell fragment, so it is negligible, solve current buzzer pin insufficient rigidity and lead Cause to there is pin shearing instability during automatism card machine plug-in unit, be difficult to the defects such as cut-out.

This utility model design solution makes buzzer be more suitable for user to use automation equipment to carry out automatic insertion production.

Detailed description of the invention

Below in conjunction with the accompanying drawings and this utility model is conducted further description by embodiment:

As Figure 1-5, the AI plug-in type buzzer of a kind of square pin, including face-piece and drain pan, face-piece and drain pan clamping.

Being provided with piezo in the space that face-piece and drain pan are constituted, piezo is arranged below two guide pins, guide pin include elasticity arm and Guide pin pin, is provided with guide pin contact on the downside of the top of elasticity arm, drain pan is provided with the groove accommodating sheet-type guide pin shell fragment.Bullet The thickness of the arm of force is less than 0.28mm, and the thickness of guide pin pin is 0.30mm-0.60mm.

Elasticity arm is connected with guide pin pin by sheet-type guide pin shell fragment, with electric resistance welding or Laser Welding mode by sheet-type guide pin bullet Sheet and guide pin pin riveted, make guide pin elasticity arm THICKNESS CONTROL within 0.30mm, and now piezo is produced by guide pin elastic force Pressure will be far below the resilience force of piezo, and the pressure that piezo is produced by guide pin elastic force is on the impact of buzzer electrical property significantly Reduce, or even ignore.

Guide pin pin is through drain pan and extends to outside drain pan, and the cross section of guide pin pin is square, and overcomes round guide pin elastic force The excessive defect causing buzzer electrical property consistency difference.

It should be appreciated that for those of ordinary skills, can be improved according to the above description or be converted, and All these modifications and variations all should belong to the protection domain of this utility model claims.

Above in conjunction with accompanying drawing, this utility model patent is carried out exemplary description, it is clear that the realization of this utility model patent is also Do not limited by aforesaid way, if the various improvement that the method design that have employed this utility model patent is carried out with technical scheme, Or the most improved design by this utility model patent and technical scheme directly apply to other occasion, all at this utility model Protection domain in.
