Description

Technical Field

[0001] This utility model belongs to the field of spring technology, specifically a combined bridge-type spring. Background Technology

[0002] As electronic devices move towards miniaturization and high density, higher demands are placed on connectors in terms of size reduction, reliability, and sensitivity. Springs are typically assembled inside or on top of connectors. Through their elasticity, springs ensure contact pressure at conductors or contact points, thereby achieving stable electrical or mechanical connections. Combined bridge-type springs, with their compact structure and excellent elasticity, can meet the requirements of connector size reduction, reliability, and sensitivity. Traditional single-point springs may suffer from poor contact or insufficient contact area. Bridge-type springs, through their multi-point or bridge structure, can effectively increase the conductive area, enhance contact reliability and wear resistance. The bridge design can optimize the elasticity and stress distribution of the springs, reduce fatigue damage caused by repeated folding or vibration, and improve service life.

[0003] Meanwhile, a spring with application number CN202420521884.4 includes a long arm and spring arms connected to the long arm. The long arm is provided with symmetrical strip-shaped through holes. The spring arms include multiple elastic arms respectively connected to both ends of the strip-shaped through holes. The elastic arms are integrally formed with the long arm. The elastic arms at both ends of the strip-shaped through holes are mirror images. The elastic arm includes a spring plate connected to the long arm and an elastic part connected to the spring plate. The spring plate is L-shaped. The elastic part includes an extension plate connected to the spring plate and a contact plate connected to the extension plate. The extension plate is inclined, and the angle between the extension plate and the spring plate is an acute angle.

[0004] However, the following problems were found in the implementation of the relevant technology: its integrated structure is complex and the overall assembly process is difficult. When a single part is damaged, the entire spring structure needs to be replaced, which leads to increased maintenance costs. In addition, the parts cannot be mass-produced and cannot be reused. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a combined bridge-type spring sheet, which has the advantages of being installed by assembly, achieving standardization and reuse of parts in mass production, low maintenance costs, and reduced production costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a combined bridge-type spring sheet, including a crossbeam, a first spring sheet fixedly connected to the lower surface of the crossbeam, a second spring sheet fixedly connected to the lower surface of the crossbeam, an insulating film fixedly connected to the lower surface of the crossbeam, double-sided adhesive on the insulating film, and multiple spring sheet pressing areas on the first spring sheet and the second spring sheet.

[0007] Preferably, the first spring is fixed to the crossbeam by riveting, and the second spring is fixed to the crossbeam by riveting, which improves the stability and reliability of the structure, ensures the stability of the spring during use, and reduces the risk of loosening or falling off.

[0008] Preferably, the insulating film is fixedly connected to the first and second spring contacts by double-sided adhesive. This simple and quick fixing method helps improve assembly efficiency while ensuring the tightness of the insulation and preventing electrical faults.

[0009] Preferably, the insulating film is located below the first spring, the second spring, and the crossbeam, effectively isolating the conductive parts from the metal crossbeam and improving the product's safety and insulation performance.

[0010] Preferably, the surface of the crossbeam is treated with alkaline washing, and the crossbeam is made of aluminum alloy. Alkaline washing enhances the surface smoothness and adhesion. Aluminum alloy is lightweight and corrosion-resistant, which helps to reduce the overall weight and extend the service life.

[0011] Preferably, the crossbeam is formed by high pressure casting, which ensures the strength and consistency of the crossbeam. The first and second springs are formed by sheet metal stamping, which is low in cost, high in production efficiency, and convenient for mass production.

[0012] Preferably, the insulating film is made of polyimide film. Polyimide has excellent high temperature resistance and insulation properties, can remain stable in complex environments, and enhances safety.

[0013] Preferably, the first spring has six spring pressing areas and the second spring has eight spring pressing areas, which can improve the contact area and reliability of electrical contacts, improve current conduction performance, and at the same time disperse stress and extend service life.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model is installed by assembly, and the components are detachable, which facilitates the inspection, repair or replacement of damaged parts without replacing the entire spring, thus reducing maintenance costs. The modular design enables the standardization and reuse of parts in mass production, reducing molds and production time, thereby reducing production costs and facilitating rapid integration into the overall system, shortening assembly time.

[0016] 2. This utility model has high reliability, good elastic response, and excellent electrical safety performance, ensuring that the spring can maintain good conductivity even after repeated insertion and removal or changes in the working environment, reducing the failure rate and maintenance frequency. The good elastic response allows the spring to effectively adapt to small displacement changes, ensuring smooth pressing and disconnection actions, thereby improving the reliability and stability of the connection. The excellent electrical safety performance prevents electrical faults such as leakage and short circuits, greatly ensuring the safety of equipment operation and reducing potential accident hazards.

[0023] like Figures 1 to 4As shown, this utility model provides a combined bridge-type spring sheet, including a crossbeam 1, which serves as the main frame of the entire structure, supporting and connecting other components to ensure the stable arrangement of the first spring sheet 2, the second spring sheet 3, and the insulating film 4. The crossbeam 1 includes: requirements for sand holes, appearance, and deburring of the finished product, with no obvious deformation, meeting the requirements of the "Die Casting Appearance Inspection Standard" that the position, size, and shape of the mold dividing lines, injection points, and ejector pins must be reviewed and confirmed; neutral salt spray test: 48h, after which the finished product's appearance shows no penetrating corrosion and does not affect the product's strength; the lower surface of the crossbeam 1 is fixedly connected to the first spring sheet 2, which provides elasticity and conductivity, ensuring good conduction and disconnection under external force; the lower surface of the crossbeam 1 is fixedly connected to the second spring sheet 3, which works in conjunction with the first spring sheet 2 to enhance elasticity and conductivity stability. To optimize connection reliability, the first spring 2 and the second spring 3 are first ground and then heat-treated. The surfaces of the first spring 2 and the second spring 3 are free of sharp corners, oil stains, and burrs, and no obvious scratches or other defects are allowed. An insulating film 4 is fixedly connected to the lower surface of the crossbeam 1 to isolate different circuit parts, prevent leakage, maintain electrical safety, and protect conductive parts from interference. Double-sided adhesive 5 is provided on the insulating film 4 to fix the insulating film 4 to the structure and ensure that each component remains stable during assembly. Multiple spring pressing areas 6 are provided on the first spring 2 and the second spring 3. The spring pressing area 6 is a pressed area with a specific shape and elasticity to control the elastic deformation and conduction state of the spring. The surface of the finished device is free of sharp corners, oil stains, and burrs, and no obvious scratches or other defects are allowed.

[0024] Specifically, the first spring 2 is fixed to the crossbeam 1 by press riveting, and the second spring 3 is fixed to the crossbeam 1 by press riveting.

[0025] Furthermore, the insulating film 4 is fixedly connected to the first spring 2 and the second spring 3 by double-sided adhesive 5.

[0026] Furthermore, the insulating film 4 is located below the first spring 2, the second spring 3, and the crossbeam 1.

[0027] It is worth noting that the surface of beam 1 has undergone alkaline washing treatment, and beam 1 is made of aluminum alloy.

[0028] It is worth noting that the crossbeam 1 is formed by high pressure casting, while the first spring 2 and the second spring 3 are formed by sheet metal stamping.

[0029] It is worth mentioning that the insulating film 4 is made of polyimide film.

[0030] It is worth emphasizing that the number of shrapnel suppression zones 6 on the first shrapnel 2 is six, and the number of shrapnel suppression zones 6 on the second shrapnel 3 is eight.

[0031] The insulating film 4 is existing technology and will not be described further. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described further. The "front, back, left, and right" views of this device are... Figure 1 The direction shown in the diagram is the reference.

[0032] Working principle: The crossbeam 1, the first spring 2, and the second spring 3 are fixed by riveting. The insulating film 4 is fixed to the crossbeam 1, the first spring 2, and the second spring 3 by double-sided adhesive 5. The insulating film 4 covers the first spring 2, the second spring 3, and the crossbeam 1. The spring pressing area 6 of the first spring 2 and the second spring 3 is shaped into an elastic structure. The whole assembly forms a complete connection module. The finished surface of this device is free of sharp corners, thorns, oil stains, and burrs. The surface is not allowed to have obvious scratches or other defects. When external pressure or signals are applied to the first spring 2 and the second spring 3, the springs deform, thereby realizing electrical connection and disconnection. Under the action of the spring pressing area 6, the first spring 2 and the second spring 3 achieve conductive conduction or non-conductive disconnection. The elastic design of the first spring 2 and the second spring 3 ensures that good contact and conduction can still be maintained after multiple insertions and removals. The insulating film 4 isolates different electrical parts to ensure safety.
