Description

A kind of AI plug-in types buzzer

Technical field

The utility model is related to a kind of buzzer, the AI plug-in type buzzers of more particularly to a kind of oval pin.

Background technology

Thin plate pin braid buzzer its pin in the market uses thickness metallic conductor within 0.20mm mostly Guide pin is designed, and there is guide pin pin insufficient rigidity, and user, which has pin when carrying out automatism card machine plug-in unit and is difficult cut-out etc., to be lacked Fall into；And using thickness to be designed in more than 0.20mm (or diameter is in 0.2mm) metallic conductor guide pin, its guide pin elastic force is more than buzzing The tension force of piece, tension variation is the important leading factor of resonant frequency of buzzer, directly results in the change of buzzer electrical property consistency Difference, quality controllable degree declines to a great extent.

The buzzer of prior art, its guide pin is connected by sheet-type guide pin shell fragment with piezo, but its guide pin pin It is circle, and circular guide pin has that elastic force is excessive, and then is easily caused the poor electrical performance of buzzer, pin shearing is unstable etc. Defect.

Drawbacks described above, is worth improving.

The content of the invention

In order to overcome the shortcomings of existing technology, the utility model provides a kind of AI plug-in types buzzer.

Technical solutions of the utility model are as described below：

Set in the cavity that a kind of AI plug-in types buzzer, including face-piece and drain pan, the face-piece and the drain pan are constituted There is piezo, two guide pins are provided below in the piezo, it is characterised in that the guide pin includes elasticity arm and guide pin draws Pin, the elasticity arm top is provided with guide pin contact, and the guide pin contact is connected with the piezo, and the elasticity arm end is set Guide pin shell fragment is equipped with, the guide pin shell fragment is connected with the guide pin pin, the guide pin pin and the piezo vertical distribution, Two guide pin pins are parallel across the drain pan, the ellipsoidal cross section or square of the guide pin pin.

Further, the oval major axis is 0.50mm-1.0mm, and short axle is 0.3-0.8mm.

Further, the thickness of the elasticity arm is less than 0.30mm.

Further, the guide pin shell fragment is connected with the guide pin pin by welding or riveted.

Further, the face-piece and the drain pan are by snapping connection.

Further, the drain pan sets fluted, and the groove matches with the guide pin shell fragment.

According to the utility model of such scheme, its advantage is, the utility model overcomes round guide pin elastic force mistake Big to cause the defect of buzzer electrical property consistency difference, the ellipsoidal cross section of guide pin pin, its major axis is 0.50mm-1.0mm, Short axle is 0.3-0.8mm, greatly reduces the pressure influence that guide pin shell fragment is produced to piezo, solves buzzer pin rigidity Deficiency causes to exist during automatism card machine plug-in unit that pin shearing is unstable, be difficult the defects such as cut-out, and the utility model is simple in construction, Cost is low, is adapted to carry out automatic insertion batch production using automation equipment.

Embodiment

Below in conjunction with the accompanying drawings and the utility model is further described embodiment：

As Figure 1-4, a kind of AI plug-in types buzzer, including face-piece 4 and drain pan 2, the face-piece 4 and the drain pan 2 By snapping connection, piezo 3 is provided with the cavity that the face-piece 4 and the drain pan 2 are constituted, the piezo 3 is set below Two guide pins 1 are equipped with, the guide pin 1 includes elasticity arm 5 and guide pin pin 6, and the top of elasticity arm 5 is provided with guide pin contact 8, The guide pin contact 8 is connected with the piezo 3, and the elasticity arm end 5 is provided with guide pin shell fragment 7, and guide pin shell fragment 7 is in thin plate Type, the guide pin shell fragment 7 is connected with the guide pin pin 6 by welding or riveted, the guide pin pin 6 and the piezo 8 Vertical distribution, two guide pin pins 6 are parallel across the drain pan 2, the ellipsoidal cross section of the guide pin pin 6 or side Shape.

The oval major axis is 0.50mm-1.0mm, and short axle is 0.3-0.8mm, and the thickness of the elasticity arm 5 is less than 0.30mm, the drain pan 2 sets fluted, and the groove matches with the guide pin shell fragment 7.

The utility model overcomes round guide pin elastic force is excessive to cause the defect of buzzer electrical property consistency difference, guide pin pin Ellipsoidal cross section, its major axis be 0.50mm-1.0mm, short axle is 0.3-0.8mm, greatly reduces guide pin shell fragment to honeybee The pressure influence that the piece that rings is produced, solving buzzer pin insufficient rigidity causes the presence of pin shearing shakiness during automatism card machine plug-in unit Determine, be difficult the defects such as cut-out, the utility model is simple in construction, and cost is low, be adapted to criticize using automation equipment progress automatic insertion Amount production.

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

Exemplary description is carried out to the utility model patent above in conjunction with accompanying drawing, it is clear that the reality of the utility model patent Now it is not subject to the restrictions described above, as long as the method for employing the utility model patent conceives various with technical scheme progress Improve, or it is not improved the design of the utility model patent and technical scheme are directly applied into other occasions, in this reality With in new protection domain.
