Description

Technical Field

[0001] This utility model relates to the field of mobile phone spring technology, specifically a mobile phone spring. Background Technology

[0002] Mobile phone spring contacts are components made of elastic metal sheets or similar materials, widely used inside mobile phones. Mobile phone spring contacts can establish reliable electrical connections between numerous electronic components and modules, allowing current to pass smoothly and ensuring that each component receives the necessary power to function normally. For example, battery spring contacts in mobile phone spring contacts can connect the mobile phone battery to the motherboard, providing power to the entire circuit system of the mobile phone.

[0003] Currently, mobile phone contact springs are often made of metal. After prolonged use, during repeated elastic deformation, in areas of stress concentration and at defects with micro-cracks, the metal may eventually break under the continuous force, affecting the contact performance and elastic function of the contact spring, thus affecting the mobile phone's performance.

The base 1 has a U-shaped structure, the upper abutment part 2 has a J-shaped structure, and the lower abutment part 3 has a rectangular plate structure. The base 1, the upper abutment part 2, and the lower abutment part 3 are integrally formed using beryllium bronze. The surface of the base 1 is provided with side cutouts 4. Two symmetrical side cutouts 4 form a group, and two groups of side cutouts 4 are arranged parallel to each other on the surface of the base 1. The side cutouts 4 have a trapezoidal structure and form a trapezoidal notch structure on the surface of the base 1. The side cutouts 4 are formed by stamping using a stamping die. The surface of the base 1 is provided with an inner cutout 5. The inner cutout 5 has a rounded rectangular structure and is formed by stamping. The die is stamped on the surface of the base 1. Multiple reinforcing rods 6 are fixedly connected to the inner wall of the inner hollow 5. The reinforcing rods 6 are beryllium bronze rods. A connecting block 7 is fixedly connected to one end of the lower abutment part 3 of the base 1. A limiting block 8 is fixedly connected to one side of the connecting block 7. The limiting block 8 is C-shaped. One end of the limiting block 8 is fixedly connected to the inner wall of the side hollow 4 on the surface of the base 1. The other end of the limiting block 8 is in contact with the upper surface of the base 1. Two sets of connecting blocks 7 and limiting blocks 8 are symmetrically arranged.

The upper protrusion 9 and the lower protrusion 10 are formed by welding tin-lead alloy.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, beryllium bronze sheet is stamped using a stamping die and stamping equipment to form a base 1, an upper abutment 2, and a lower abutment 3.

Using a welding process, an upper protrusion 9 and a lower protrusion 10 are formed on the upper surface of the upper abutment 2 and the lower surface of the lower abutment 3, respectively, using tin-lead alloy welding.

The lower abutment 3 is connected to the mobile phone motherboard, and the upper abutment 2 is connected to the electronic components. The lower protrusion 10 and upper protrusion 9 can increase the conductivity of the device, increase the conductivity effect of the device, and increase the overall practicality.
