Description

Technical Field

[0001] The utility model relates to the technical field of buzzer sheets, in particular to a buzzer sheet convenient for wiring. Background Art

[0002] A buzzer sheet is an element that uses the piezoelectric effect to generate sound, also known as a piezoelectric ceramic buzzer. It is made of a piezoelectric ceramic material, usually sodium zirconate titanate (NaZrTiO3) or lead zirconate titanate (Pb[Zr,Ti]O3), etc., with metal electrodes pasted on both sides. When an external electric field acts on the buzzer sheet, the piezoelectric ceramic will deform and generate mechanical vibration. This vibration will generate sound waves inside the buzzer sheet, thereby emitting sound. Due to the simple structure and working principle of the buzzer sheet, it is inexpensive and widely used. The buzzer sheet is usually used as a sound-emitting element for prompting sounds in electronic devices such as alarms, timers, electronic clocks, electronic scales, mobile phones, etc.

[0003] The prior art has the following deficiencies: In the prior art, the application number is 201820731395.6, which proposes a vibrating buzzer sheet, belonging to the field of piezoelectric ceramics, aiming to provide a vibrating buzzer sheet convenient for connecting leads to a metal substrate to solve the problem that the connection between the lead and the metal substrate is not firm due to the small contact area between the lead and the top surface of the metal substrate. The key points of its technical solution are as follows: A vibrating buzzer sheet includes a metal substrate and a piezoelectric ceramic sheet glued to the metal substrate. One end of the metal substrate extends integrally along its length direction to form a connecting portion, and a welding area for welding the lead is formed in the middle of the connecting portion. The welding area is square and is located on the side of the connecting portion close to the piezoelectric ceramic sheet.

[0004] When the above device is used, it extends out the connecting portion and simultaneously opens a receiving groove and a containing groove to ensure the convenience of connecting the lead. Since the buzzer sheet itself is relatively thin, for most models of buzzer sheets, the way of opening the groove will result in a relatively shallow groove. When using solder welding, it is not sufficient to place the connecting end of the lead, and it is not enough to achieve the effect of convenient connection of the lead of the buzzer sheet. At the same time, when using the welding method, when the buzzer sheet needs to be replaced during the later maintenance of the corresponding electronic device, welding needs to be carried out again, and the lead connection form of the buzzer sheet cannot be disassembled and assembled conveniently. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the utility model provides a buzzer sheet convenient for wiring to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A buzzer sheet convenient for wiring includes a metal sheet and a lead. A ceramic sheet is arranged on the metal sheet, a silver layer is arranged on the ceramic sheet, a connection assembly is arranged on the metal sheet, an adhesive is arranged on the connection assembly, and a wire is arranged inside the lead;

[0007] The connecting component includes a fitting section, a through hole, a winding section, and a supporting section. A through hole is provided on the connecting component, and a winding section is arranged at one end of the connecting component.

[0008] As a preferred technical solution of the present utility model: The ceramic sheet is fixedly pasted in the middle of the metal sheet, and the silver layer is formed by coating silver paste on the ceramic sheet.

[0009] As a preferred technical solution of the present utility model: The metal sheet is specifically made of copper, and the end of the wire exposes the lead and is wound into a ring shape.

[0010] As a preferred technical solution of the present utility model: The fitting section is fixedly installed at one end of the connecting component. The part of the connecting component close to the fitting section is the supporting section, and the other part is an arched structure.

[0011] As a preferred technical solution of the present utility model: The width and thickness of the winding section are both adapted to the through hole. The winding section is an arched structure and is integrally formed with the connecting component.

[0012] As a preferred technical solution of the present utility model: The winding section, the connecting component, and the fitting section are all made of soft steel. There are two groups of the connecting components and their structures are the same. The fitting sections on the two groups of connecting components respectively contact the metal sheet and the silver layer and are fixed by adhesive.

[0013] Compared with the prior art, the present utility model provides a buzzer sheet convenient for wiring, which has the following

[0014] Beneficial effects:

[0015] 1. For this buzzer sheet convenient for wiring, by setting the connecting component, the fitting section, the through hole, the winding section, the supporting section, and the wire, the wire is wound into a ring shape and sleeved on the connecting component at a position close to the through hole. Hold the end of the winding section and pass it through the through hole and pull it outwards. At this time, the arched structure position in the connecting component is damaged to generate a winding effect and form a ring shape. Then, bend the winding section inwards to damage the arched structure of the winding section, so that the winding section is wound into a ring shape and abuts against the outside of the connecting component, thereby restricting the position of the wire sleeved in the connecting component to form a double-ring knot structure. The friction generated by the self-contact of the wound winding section and the friction generated by the contact between the winding section and the connecting mechanism can prevent the wire from easily detaching from the connecting component. The connection between the lead and the buzzer sheet is convenient, and soldering is no longer required.

[0016] 2. The buzzer piece facilitating wiring. When it is necessary to disassemble the buzzer piece, the arched section and the winding section on the connection component can be straightened to maintain the arched structure, and then the wire can be directly taken out from the connection component. When maintaining the corresponding electronic device later, if it is necessary to replace the buzzer piece, the lead wire can be quickly separated from the connection component, achieving the effect of convenient disassembly and assembly of the buzzer piece.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , in this implementation: A buzzer piece facilitating wiring includes a metal sheet 1 and a lead wire 4. Through the lead wire 4, it is convenient to connect the buzzer piece with the corresponding electronic device. A ceramic sheet 2 is arranged on the metal sheet 1, a silver layer 3 is arranged on the ceramic sheet 2, a connection component 5 is arranged on the metal sheet 1, an adhesive 6 is arranged on the connection component 5, and a wire 7 is arranged inside the lead wire 4;

[0024] The connection component 5 includes a fitting section 501, a through hole 502, a winding section 503 and a support section 504. A through hole 502 is opened on the connection component 5, and a winding section 503 is arranged at one end of the connection component 5. Through the through hole 502, it is convenient for the winding section 503 to pass through.

[0025] In this embodiment, the ceramic sheet 2 is fixedly pasted in the middle of the metal sheet 1, and the silver layer 3 is formed by coating silver paste on the ceramic sheet 2;

[0026] Specifically, the positive electrode and the negative electrode of the buzzer sheet can be formed through the silver layer 3 and the metal sheet 1;

[0027] In this embodiment, the metal sheet 1 is specifically made of copper, and the end of the wire 7 exposes the lead 4 and is wound into a ring shape;

[0028] Specifically, winding the wire 7 into a ring shape can facilitate the combination with the connection component 5 to form a double-ring knot structure;

[0029] In this embodiment, the fitting section 501 is fixedly installed at one end of the connection component 5. The part of the connection component 5 close to the fitting section 501 is the support section 504, and the other part is an arched structure;

[0030] Specifically, through the fitting section 501, the connection component 5 can be conveniently connected to the metal sheet 1 and the silver layer 3, and through the support section 504, the winding section 503 can be supported;

[0031] In this embodiment, the width and thickness of the winding section 503 are both adapted to the through-hole 502. The winding section 503 is an arched structure and is integrally formed with the connection component 5;

[0032] Specifically, through the winding section 503, the arched part of the connection component 5 can be made more stable after being wound;

[0033] In this embodiment, the winding section 503, the connection component 5, and the fitting section 501 are all made of soft steel. There are two groups of connection components 5 and their structures are the same. The fitting sections 501 on the two groups of connection components 5 respectively contact the metal sheet 1 and the silver layer 3 and are fixed by the adhesive 6;

[0034] Specifically, through the adhesive 6, the connection component 5 can be stably installed on the metal sheet 1 and the silver layer 3 and can conduct current.

[0035] Working principle and usage process of the utility model: When connecting the lead 4, first ensure that the connection component 5 is in an extended state. Then, strip out the wire 7 inside the lead 4, wind the wire 7 into a ring and tighten it. Place the ring-shaped wire 7 on the connection component 5 near the through-hole 502. Then, hold the end of the winding section 503 and pass it through the through-hole 502 and pull it outwards. At this time, the position of the arched structure in the connection component 5 is damaged to produce a winding effect and form a ring. Then, bend the winding section 503 inward to damage the arched structure of the winding section 503, so that the winding section 503 winds into a ring and abuts against the outside of the connection component 5, thereby restricting the position of the wire 7 sleeved in the connection component 5 and forming a double-loop knot structure. After winding, the winding section 503 can always maintain the stable connection of the wire 7 without external force pulling. The connection between the lead 4 and the buzzer piece is convenient, and soldering is no longer required. When the buzzer piece needs to be disassembled, the arched section and the winding section 503 on the connection component 5 can be straightened to maintain the arched structure, and then the wire 7 can be directly taken out of the connection component 5. When maintaining the corresponding electronic device later, if the buzzer piece needs to be replaced, the lead 4 can be quickly detached from the connection component 5, achieving the effect of convenient disassembly and assembly of the buzzer piece.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
