Description

Technical Field

[0001] This utility model relates to the field of electronic components technology, and in particular to a buzzer docking pin structure. Background Technology

[0002] As a commonly used electronic sound-generating component, the buzzer is widely used in many fields such as automotive electronics, consumer electronics, industrial control, and security alarms. It undertakes important functions such as signal indication and alarm. In practical applications, the buzzer usually needs to be electrically connected to the external circuit through pins to realize signal transmission and drive sound generation.

[0003] Currently, most buzzers on the market use a fixed-pin structure, meaning the pin position and spacing are determined during manufacturing and cannot be adjusted. This fixed-pin structure has many limitations. Firstly, different circuit designs and installation environments have varying requirements for buzzer pin spacing and installation position, making fixed-pin buzzers difficult to meet diverse usage needs. When encountering situations where the circuit interface pin spacing does not match the buzzer pins, either the circuit board needs to be redesigned, or a buzzer with special specifications must be customized. This not only increases R&D costs and production cycles but also limits the product's versatility and flexibility.

[0004] Therefore, how to design a buzzer docking pin structure that can flexibly adjust the pin position, ensure electrical connection stability, and improve installation reliability has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to provide a buzzer docking pin structure. This invention can quickly adapt to external circuit interfaces with different spacings through the sliding fit design of adjustable pin seat and movable pin, without the need to redesign the circuit board or customize a buzzer of special specifications, thereby reducing research and development and production costs.

[0006] A buzzer docking pin structure according to an embodiment of the present invention includes a buzzer body and an adjustable pin seat. The adjustable pin seat is fixedly installed at the center of the bottom of the buzzer body by screws. Pins are symmetrically arranged on the left and right sides of the bottom of the buzzer body. Pin interfaces are symmetrically opened on the top two sides of the adjustable pin seat. The pins are inserted into the pin interfaces. Through holes are symmetrically opened on the left and right sides inside the adjustable pin seat. Horizontally arranged conductive plates are fixedly installed on the top of the inner side of the two sets of through holes by welding. The two sets of pin interfaces are electrically connected to the two sets of conductive plates by wires. A sliding groove extending vertically is provided inside the through hole. A movable seat is slidably installed in the sliding groove. A conductive sheet that is in close contact with the bottom surface of the conductive plate is fixedly installed on the top of the movable seat. A movable pin is vertically installed inside the movable seat, and the top of the movable pin is fixedly connected to the center of the bottom surface of the conductive sheet. The bottom of the movable pin extends out of the bottom of the through hole for external circuit connection.

[0007] Furthermore, protrusions are symmetrically installed on the left and right sides of the movable seat. The protrusions are cuboid in shape, and their length direction is consistent with the extension direction of the slide groove. Slider blocks are slidably installed on the lower left and right sides of the inner wall of the slide groove. An elastic reset mechanism is provided between the top of the slider and the bottom of the protrusion.

[0008] Furthermore, the elastic reset mechanism includes a spring fixedly mounted on the top of the slider, the top of the spring being fixedly connected to the bottom of the protrusion. When the spring is in its natural state, the conductive sheet and the conductive plate maintain surface contact for electrical conduction.

[0009] Furthermore, symmetrical limiting grooves are formed on the lower left and right sides of the inner wall of the slide groove. The limiting grooves are arranged along the extension direction of the slide groove. A limiting block is integrally formed on the outer side of the slider. The limiting block can be movably installed in the limiting groove, and the width of the limiting block matches the width of the limiting groove to form a sliding guide fit.

[0010] Furthermore, the number of springs is at least two sets, and multiple sets of springs are evenly distributed and installed on the top of the slider along the length direction of the slider, and the spring constant is -N / m, which can apply a stable upward thrust.

[0011] Furthermore, the conductive sheet is made of copper alloy with a thickness of 0.3-0.5 mm, and its surface is plated with a tin layer with a thickness of 5-10 μm. The conductive plate is made of brass plate with a thickness of 1-2 mm, and the contact area between the two is not less than 10 mm². 2 .

[0012] Furthermore, the movable seat is made of insulating engineering plastic, and its external dimensions match the cross-sectional dimensions of the slide groove, forming a sliding fit with a gap of 0.1-0.3mm.

[0013] Furthermore, the inner diameter of the pin interface is 0.8-1.2mm, forming an interference fit of 0.05-0.1mm with the outer diameter of the pin. The pin is made of tin-plated copper wire with a length of 8-12mm.

[0014] Furthermore, the depth of the limiting groove is 2-3mm, the height of the limiting block is 1.5-2.5mm, and the sliding stroke formed by the two together is 5-10mm, which meets the adjustment range requirements of the movable pin.

[0015] Furthermore, the horizontal distance between the axis of the perforation and the axis of the pin interface is 5-8mm, and the two sets of perforations are symmetrically arranged about the central axis of the adjustable pin seat.

[0016] The beneficial effects of this utility model are:

[0017] 1. In this utility model, the movable pin can slide and adjust within the groove. With the help of the spring and the limiting structure, the adjustment stroke reaches 5-10mm. When the movable pin slides and adjusts, its top conductive plate can make close contact with the conductive plate. Since the conductive plate is connected by the pins of the buzzer itself, the circuit can be ensured in any position. This allows for quick adaptation to external circuit interfaces with different spacings, eliminating the need for customized buzzers. This significantly improves the applicability of the product in diverse installation environments and reduces the cost of use and installation difficulty.

[0018] 2. In this utility model, the movable seat and the slide groove form a precise sliding fit, the limiting block and the limiting groove of the slider provide accurate guidance, and multiple sets of evenly distributed springs provide stable support, ensuring that the movable pin slides smoothly during the adjustment process and will not be displaced due to vibration or other factors during operation, thus ensuring the long-term stable operation of the structure.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0030] like Figure 1-5 As shown, this utility model discloses a buzzer docking pin structure, including a buzzer body 1 and an adjustable pin seat 2.

[0031] The adjustable pin seat 2 is fixedly installed at the center of the bottom of the buzzer body 1 by screws. This fixing method ensures the stability and reliability of the connection between the two and facilitates the use of the overall structure in the future.

[0032] The buzzer body 1 has pins 6 symmetrically arranged on the left and right sides of the bottom. The adjustable pin seat 2 has pin interfaces 7 symmetrically opened on the top sides. The pins 6 are inserted into the pin interfaces 7 by interference fit. The interference fit makes the connection between the pins 6 and the pin interfaces 7 tight, ensuring the stability of the electrical connection.

[0033] The adjustable pin seat 2 has symmetrical through holes 3 on both the left and right sides inside. The top of the inner side of the two sets of through holes 3 is fixedly installed with a horizontally arranged conductive plate 8 by welding. The welding method can ensure a firm connection between the conductive plate 8 and the adjustable pin seat 2, and ensure good conductivity.

[0034] Two sets of pin interfaces 7 are electrically connected to two sets of conductive plates 8 via wires, thereby realizing the transmission of electrical signals between the buzzer body 1 and the subsequent circuit.

[0035] The perforation 3 has a vertically extending groove 9 inside, and a movable seat 4 is slidably installed in the groove 9.

[0036] The movable seat 4 has symmetrical protrusions 11 installed on its left and right sides. The protrusions 11 are rectangular in shape and their length direction is consistent with the extension direction of the slide groove 9.

[0037] Slider 12 is slidably installed on the lower left and right sides of the inner wall of the slide groove 9. An elastic reset mechanism composed of spring 14 is provided between the top of slider 12 and the bottom of protrusion 11.

[0038] The top of the spring 14 is fixedly connected to the bottom of the protrusion 11, and there are at least two sets of springs 14. Multiple sets of springs 14 are evenly distributed and installed on the top of the slider 12 along the length of the slider 12. The elastic coefficient of the spring 14 is 5-10 N / m. In its natural state, the conductive sheet 10 and the conductive plate 8 maintain surface contact and conduction. This design ensures that the movable seat 4 can slide stably in the slide groove 9, and at the same time ensures good electrical connection when there is no external force.

[0039] In addition, symmetrical limiting grooves 15 are provided on the lower left and right sides of the inner wall of the slide groove 9. The limiting grooves 15 are set along the extension direction of the slide groove 9. The outer side of the slider 12 is integrally formed with a limiting block 13. The limiting block 13 can be movably installed in the limiting groove 15, and the width of the limiting block 13 matches the width of the limiting groove 15 to form a sliding guide fit. The depth of the limiting groove 15 is 2-3mm, and the height of the limiting block 13 is 1.5-2.5mm. The sliding stroke formed by the two is 5-10mm, which meets the adjustment range requirements of the movable pin 5 and effectively prevents the movable seat 4 from disengaging from the slide groove 9 during the sliding process.

[0040] A conductive sheet 10 is fixedly installed on the top of the movable base 4, which is in close contact with the bottom surface of the conductive plate 8. The conductive sheet 10 is made of copper alloy with a thickness of 0.3-0.5mm and its surface is plated with a tin layer with a thickness of 5-10μm. The conductive plate 8 is made of brass plate with a thickness of 1-2mm, and the contact area between the two is not less than 10mm². 2 To ensure good electrical conductivity.

[0041] The movable base 4 has a vertically inserted movable pin 5 installed inside, and the top of the movable pin 5 is fixedly connected to the center of the bottom surface of the conductive sheet 10. The lower end of the movable pin 5 extends out of the bottom of the through hole 3 for external circuit connection.

[0042] In practical use, when it is necessary to adjust the connection position between the buzzer and the external circuit, external force can be applied to the movable pin 5 to make the movable seat 4 slide in the slide groove 9, and the spring 14 is compressed or stretched. After the adjustment is completed, the external force is removed, and the movable seat 4 returns to its original position under the elastic restoring force of the spring 14, ensuring that the conductive sheet 10 and the conductive plate 8 maintain good electrical contact, and realizing a stable electrical connection between the buzzer and the external circuit.

[0043] As a preferred example of this application, the movable seat 4 is made of insulating engineering plastic, and its external dimensions match the cross-sectional dimensions of the slide groove 9 to form a sliding fit with a gap of 0.1-0.3mm. The cross-sectional shape of the slide groove 9 is rectangular or T-shaped, which effectively prevents the movable seat 4 from shaking during sliding and ensures the stability of the connection.

[0044] As a preferred example of this application, the inner diameter of the pin interface 7 is 0.8-1.2mm, forming an interference fit of 0.05-0.1mm with the outer diameter of the pin 6. The pin 6 is made of tin-plated copper wire and has a length of 8-12mm, which further ensures a reliable connection between the buzzer body 1 and the adjustable pin seat 2.

[0045] As a preferred example of this application, the horizontal distance between the axis of the perforation 3 and the axis of the pin interface 7 is 5-8mm, and the two sets of perforations 3 are symmetrically arranged about the central axis of the adjustable pin seat 2, which ensures the symmetry and stability of the entire structure.

[0046] Working principle: The pins 6 at the bottom of the buzzer body 1 are inserted into the pin interface 7 at the top of the adjustable pin seat 2 via an interference fit. This tight connection ensures the stability of the initial electrical connection. The pin interface 7 is electrically connected to the conductive plate 8 fixed inside the through hole 3 at the top of the adjustable pin seat 2 via a wire, thereby transmitting the electrical signal generated by the buzzer body 1 to the conductive plate 8. The conductive plate 10 at the top of the movable seat 4 maintains surface contact with the conductive plate 8, and the movable pin 5 inside the movable seat 4 is fixedly connected to the conductive plate 10. In this way, the electrical signal can be transmitted from the conductive plate 8 through the conductive plate 10 to the movable pin 5, and finally connected to the external circuit through the lower end of the movable pin 5 to realize the output of the buzzer's electrical signal. When the buzzer needs to be adjusted to activate its connection with the external circuit, an external force is applied to the movable pin 5. The movable pin 5 causes the movable seat 4 to slide within the groove 9 in the through hole 3. The protrusions 11 on both sides of the movable seat 4 are connected to the spring 14 on the top of the slider 12. During the sliding process, the spring 14 is compressed, storing elastic potential energy. Simultaneously, the limiting block 13 on the outer side of the slider 12 slides within the limiting groove 15, ensuring that the movable seat 4 slides smoothly in the predetermined direction, preventing deviation or disengagement. Once the movable pin 5 is adjusted to the appropriate position, the external force is removed. The spring 14, with its elastic restoring force, pushes the protrusion 11, causing the movable seat 4 to reset, ensuring that the conductive sheet 10 and the conductive plate 8 are in close contact again, maintaining a good electrical connection. At this point, the movable pin 5 is connected to the external circuit in its new position, achieving flexible adaptation of the buzzer's connector pin structure to different installation environments and meeting diverse usage needs.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
