Abstract
Description
Technical Field
[0001] This utility model relates to the field of shrapnel, specifically a high-strength shrapnel. Background Technology
[0002] Spring contacts are commonly used components in electronic products. One end is soldered to a circuit board, while the other end elastically contacts an electronic component or metal frame, thereby electrically connecting the electronic component to the circuit board or providing electrostatic discharge (ESD) protection for the circuit board. With the continuous development of microelectronics technology, the size of various electronic components is becoming smaller and smaller. In circuit boards, spring contacts are often used as intermittent connection devices. By setting up these spring contacts, on the one hand, electrical connection between electronic components and the circuit board can be achieved; on the other hand, when an electronic component needs ESD discharge, it connects to a grounding point on the circuit board through the spring contact to achieve ESD discharge.
[0003] Existing contact springs also have the following drawbacks: They are typically smooth, flat surfaces fixed to the circuit board via simple plug-in connections. This method of connection is prone to displacement or detachment when subjected to frequent vibrations or external impacts from electronic devices, leading to poor contact. For example, in portable electronic devices such as mobile phones or tablets, the devices may be subjected to collisions or drops during use. In such cases, the contact springs can easily lose their original elastic support, resulting in unstable connections between electronic components and the circuit board, causing poor contact and affecting the normal operation of the device.

[0006] Furthermore, the side of the fixing block protrudes outward to form two abutting pieces, which are symmetrically arranged.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] The following is combined Figure 1 and Figure 2 A detailed description of a high-strength spring sheet of this utility model is provided below:
[0018] A high-strength spring includes a conductive plate 1. One end of the conductive plate 1 extends outward to form a fixing block 3. Two arc-shaped locking blocks 4 are provided at one end of the fixing block 3. The two arc-shaped locking blocks 4 are symmetrically arranged. The edges of the arc-shaped locking blocks 4 protrude outward to form arc-shaped locking portions 5. The inner walls of the arc-shaped locking blocks 4 protrude outward to form several barb portions 6. Adjacent barb portions 6 are symmetrically arranged. The sides of the fixing block 3 protrude outward to form two abutment pieces 7. The two abutment pieces 7 are symmetrically arranged. The conductive plate 1 is square in shape. The surface of the conductive plate 1 is electroplated with a silver plating layer 2. The thickness of the conductive plate 1 is greater than the thickness of the silver plating layer 2. The surface of the fixing block 3 is smooth. The conductive plate 1 is made of copper.
[0019] In this embodiment, two symmetrical abutment pieces 7 are provided on the side of the fixing block 3, which provide additional lateral support force, enhance the stability of the spring sheet under lateral force, effectively prevent the spring sheet from shifting or shaking during use, and improve the load-bearing capacity and service life of the spring sheet. The conductive plate 1 is designed in a square shape, which facilitates matching and installation with other components, and improves the versatility and applicability of the spring sheet.
[0020] The silver plating layer 2 electroplated on the surface of the conductive plate 1 significantly improves the conductivity and oxidation resistance of the spring. The silver plating layer 2 effectively reduces contact resistance, ensuring stable current transmission, while the high oxidation resistance of silver also extends the service life of the spring. The design that the thickness of the conductive plate 1 is greater than the thickness of the silver plating layer 2 ensures the mechanical strength of the spring and prevents deformation or damage during use due to the conductive plate 1 being too thin.
[0021] The smooth surface design of the fixing block 3 reduces friction with other components, making it easier to install and remove the spring, while also reducing wear caused by friction and improving the durability of the spring.
[0022] The conductive plate 1 is made of copper. Copper has excellent conductivity and good mechanical properties, which can ensure that the spring maintains stable electrical performance when high current passes through it. At the same time, the high strength and toughness of copper also enable the spring to withstand greater pressure and tension, enhancing the overall performance and reliability of the spring.
[0023] In use, the spring is directly pressed into the circuit board under pressure. It is firmly connected to the circuit board through the arc-shaped snap-fit part 5 and the barb part 6, so that the spring is stuck on the circuit board and prevents it from loosening due to vibration or external force during use. In addition, the abutting piece 7 at one end abuts against one side of the circuit board, and the abutting piece 7 at the other end abuts against other components. After abutting, the abutting piece 7 generates elastic force between the circuit board and other components, which can further make the spring installation more stable and firm, so that the spring can be fixed to the circuit board without soldering.
[0024] This embodiment of a high-strength spring sheet achieves a stable connection by setting a fixing block 3 at one end of a conductive plate 1, and setting symmetrical arc-shaped locking blocks 4 and arc-shaped locking parts 5 on the fixing block 3. The barb part 6 set on the inner wall of the arc-shaped locking block 4 further enhances the connection strength between the spring sheet and the connecting parts, preventing loosening due to vibration or external force during use, and ensuring the reliability and stability of the connection.
[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
