Description

Technical Field

[0001] This application relates to the field of electronic component connections, and in particular to a connection structure for electronic components. Background Technology

[0002] In the field of electronic equipment, the connection structure of electronic components is a crucial part of ensuring the normal operation of electronic devices. With the rapid development of electronic technology, various electronic devices are constantly being innovated, placing higher demands on the stability and versatility of connections between electronic components. A good connection structure not only ensures stable transmission of electronic signals but also improves the overall performance and reliability of electronic equipment, thereby promoting the widespread application of electronic equipment in various fields. Existing electronic component connections typically employ a connection structure composed of O-type or C-type springs and connecting terminals. Specifically, the spring is soldered to the electronic component, and then the connecting terminal is pressed into the spring's insertion port. The outer wall of the connecting terminal presses against the inner wall of the spring, causing the spring to open and clamp the connecting terminal. Electrical communication is achieved through the free end of the connecting terminal with other electronic components, thus connecting the electronic components at both ends of the spring and the connecting terminal. Existing connector structures are simple in design and can meet basic connection requirements to a certain extent. In the production process of electronic equipment, this simple connection structure is easy to manufacture and install, and the cost is relatively low, so it is widely used in some electronic devices with low connection requirements. However, existing connection structures still have significant shortcomings in practical applications. On the one hand, this connection method is limited to specific types of connector terminals. Connecting terminals with larger diameters are prone to squeezing the spring contacts until they break, while connecting terminals with smaller diameters are prone to loosening from the spring contacts. It cannot be applied to a variety of different types of connector terminals and has low versatility. On the other hand, after long-term use and repeated pressing and plugging, the spring contact insertion port is prone to being squeezed and deformed, making it difficult to plug in later, which further affects the service life of the spring contact. Summary of the Invention

[0003] To improve the versatility of the connection between the spring and the connecting terminal, making it applicable to various types of connecting terminals, improving connection stability, increasing the strength of the connection structure, and preventing deformation from affecting normal use after long-term use, this application provides a connection structure for electronic components.

[0004] This application provides a connection structure for electronic components, including a spring-loaded terminal and a connecting terminal. The spring-loaded terminal includes a connector for soldering electronic components. Elastic clamping members are symmetrically arranged on both sides of the connector. A cavity structure for accommodating the connecting terminal is formed between the two elastic clamping members. Each elastic clamping member includes an elastic support portion, a clamping portion, and a guide portion connected sequentially from bottom to top. The two clamping portions are arranged opposite each other, and the inner surface of each clamping portion has a concave arc-shaped structure protruding towards the other clamping portion to form a clamping cavity adapted to the outer contour of the connecting terminal. The ends of the two guide portions are inclined in a direction away from each other. When the connecting terminal is pressed down along the guide portion into the clamping cavity, the concave arc-shaped structures of the two clamping portions will tightly fit against the outer wall of the connecting terminal.

[0005] By adopting the above technical solution, the connector is used to weld electronic components, thereby achieving a reliable connection between the spring terminal and the electronic component. The connector has symmetrically arranged elastic clamping parts on both sides, forming a cavity structure between the two elastic clamping parts to clamp the connecting terminal. Each elastic clamping part is connected from bottom to top to an elastic support part, a clamping part, and a guide part. The ends of the two guide parts are inclined in opposite directions, which guides the connecting terminal when it is pressed down, allowing it to enter the clamping cavity more smoothly. The inner surface of each clamping part has a concave arc-shaped structure that convexes towards the other clamping part, forming a clamping cavity that matches the outer contour of the connecting terminal. When the connecting terminal is pressed down along the guide part into the clamping cavity, the two clamping parts can better fit and press against the outer wall of the connecting terminal according to its shape. Furthermore, because the clamping parts match the outer contour of the connecting terminal, the compression deformation of the spring insertion port is reduced during repeated pressing and insertion, extending the service life of the spring. Meanwhile, the elastic support provides elastic support for the clamping part, making the clamping effect between the clamping part and the connecting terminal more stable, ensuring stable transmission of electronic signals, improving the overall performance and reliability of electronic equipment, and increasing the opening distance between the two clamping parts to accommodate various types of connecting terminals. Compared with the existing connection structure, the elastic support part below the clamping part avoids the problem of larger diameter connecting terminals squeezing the spring, causing the solder joint between the spring and the electronic component to break, and the problem of smaller diameter connecting terminals loosening from the spring due to limited elastic deformation capacity, thus enhancing the versatility for different types of connecting terminals.

[0006] Preferably, the two clamping parts are symmetrically arranged and are both concave arc-shaped structures symmetrical in the vertical direction, and the distance between the highest points of the two clamping parts is equal to the distance between the lowest points of the two clamping parts.

[0007] By adopting the above technical solution, since the two clamping parts are symmetrically arranged and both are concave arc-shaped structures symmetrical in the vertical direction, and the distance between the highest point and the lowest point of the two clamping parts are equal, the pressure on each contact point of the connecting terminal is evenly distributed when it is clamped. This avoids uneven force on the outer wall of the spring, preventing it from sliding vertically, and improves the stability and reliability of the connection structure. Moreover, this structure results in more uniform deformation of each part during the insertion and removal of the connecting terminal, reducing wear caused by excessive local deformation and extending the service life of the connection structure.

[0008] Preferably, the radius of curvature of the concave arc structure of the two clamping parts is in the range of 40-60 mm.

[0009] By adopting the above technical solution, the radius of curvature of the concave arc structure of the two clamping parts is set to 40-60mm. Within this radius of curvature, the clamping parts can better adapt to the outer contour of the connecting terminal. When the connecting terminal is pressed down into the clamping cavity along the guide, this radius of curvature ensures that the clamping part exerts a suitable clamping force on the connecting terminal. This ensures a stable connection with the connecting terminal, preventing loosening due to insufficient clamping force, while also preventing excessive clamping force from squeezing the connecting terminal or causing excessive deformation or even breakage. As a result, this connection structure can be applied to various connecting terminals with different diameters within a certain range, greatly improving the versatility of the connection structure.

[0010] Preferably, the two elastic support portions extend from one end near the connector in a direction away from each other to form a figure-eight structure.

[0011] By adopting the above technical solution, the two elastic support parts extend outwards from the ends near the connector to form a figure-eight structure. This structure allows the elastic support parts to better distribute the pressure of the connector on the connector during the pressing of the connector terminal. Because the elastic support parts extend outwards in a figure-eight shape, the pressure originally concentrated at the connection point between the connector and the elastic support parts is distributed to a larger area along the figure-eight structure, preventing excessive pressure concentration that could damage the connector. Simultaneously, the figure-eight structure enhances the elastic deformation capability of the elastic support parts. When the connector terminal is pressed down, the elastic support parts can deform more flexibly to accommodate the insertion of the connector terminal, and can better return to their original shape after the connector terminal is pulled out. This improves the stability and durability of the entire connection structure, thereby enhancing the compatibility and versatility of the connection structure with different types of connector terminals.

[0012] Preferably, both elastic support portions are arc-shaped elastic sheets, and they are arranged symmetrically.

[0013] By adopting the above technical solution, the elastic support is designed as an arc-shaped elastic sheet, and the two are symmetrically arranged. The arc-shaped structure allows the elastic support to undergo elastic deformation under force, and the symmetrical arrangement ensures that the force exerted by the elastic support on both sides on the connecting terminal is uniform. When the connecting terminal is pressed down into the clamping cavity along the guide, the connecting terminal squeezes the clamping part, and the clamping part transmits the force to the elastic support. The elastic deformation of the arc-shaped elastic sheet can effectively buffer the impact force of the connecting terminal on the spring terminal, reduce the damage to the spring terminal, and thus improve the service life of the spring terminal. At the same time, this elastic deformation can adapt to connecting terminals of different diameters, making the connection structure more versatile for different types of connecting terminals, effectively solving the problem that existing connection structures cannot be applied to a variety of different types of connecting terminals.

[0014] Preferably, the inner surface of each arc-shaped elastic sheet is a concave arc shape that convexes toward the other arc-shaped elastic sheet.

[0015] By adopting the above technical solution, the inner surface of each arc-shaped elastic sheet is concave-arc, convex towards another arc-shaped elastic sheet. This structure allows the elastic support to distribute stress more evenly when subjected to pressure from the connecting terminal. Because the concave-arc structure increases the contact area with the connecting terminal, compared to a conventional planar structure, the pressure per unit area is reduced under the same pressure, thereby lowering the risk of damage due to excessive local stress on the elastic support. Simultaneously, the concave-arc structure also enhances the elastic deformation capability of the elastic support. When the connecting terminal is inserted and removed, the elastic support can better adapt to this deformation and more quickly and accurately return to its initial state after deformation.

[0016] Preferably, the two elastic support portions and the connector are provided with rounded corners.

[0017] By adopting the above technical solution, a rounded corner is provided between the elastic support and the connector, which effectively avoids stress concentration and allows stress to be distributed more evenly at the connection, enhancing the strength and stability of the connection structure. Simultaneously, the rounded corner makes the elastic support deform more smoothly, reducing additional losses caused by poor deformation, improving the elastic performance and service life of the elastic support, and thus enhancing the reliability and durability of the entire electronic component connection structure.

[0018] Preferably, the connector is provided with mounting holes.

[0019] By adopting the above technical solution, the connector is provided with mounting holes, which facilitates installation on other components.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. The elastic clamping member of the spring terminal is provided with a guide part. The end of the guide part is inclined in a direction away from each other. When the connecting terminal is pressed down and inserted, the guide part can guide the connecting terminal to smoothly enter the clamping cavity along the guide part. This avoids the connecting terminal directly pressing the insertion port, thereby reducing the risk of the insertion port being squeezed and deformed, and thus extending the service life of the spring. 2. The inner surface of the clamping part has a concave arc-shaped structure that protrudes towards the other clamping part, forming a clamping cavity that matches the outer contour of the connecting terminal. When connecting terminals of different diameters are pressed into the clamping cavity, the concave arc-shaped clamping part can undergo a certain degree of elastic deformation according to the diameter of the connecting terminal, thereby tightly clamping the connecting terminal. This allows the connecting structure to adapt to connecting terminals of different diameters, improving versatility. 3. The elastic support can prevent damage to the connector caused by excessive pressure concentration, and also enhances the elastic deformation capability of the elastic support. The elastic support can deform more flexibly to adapt to the insertion and removal of the connector terminal, preventing the spring from breaking. In addition, it can increase the opening distance between the two clamping parts to improve the versatility and clamping stability of the spring terminal. Attached Figure Description

[0023] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0024] This application provides a connection structure for electronic components, referring to... Figure 1 and Figure 2 This system includes spring-loaded terminals and connecting terminals. By pressing the connecting terminal vertically from directly above the spring-loaded terminal, the two terminals mate, improving connection versatility and extending the lifespan of the spring. This is because the unique structural design of the spring-loaded terminal better accommodates connecting terminals of different sizes and is less prone to deformation or damage. The connecting terminal can be various connection structures with conductive functions, such as spring-loaded pins, ejector pins, and spring-loaded pins.

[0025] Specifically, the spring-loaded terminal includes a connector for connecting electronic components and an elastic clamping member for holding the connector. The connector is made of metal, such as copper or aluminum, due to its good conductivity. The connector is flat and has mounting holes for fixing with screws or bolts, facilitating disassembly. In other embodiments, welding can also be used, which provides a more robust connection. A special connector extends downwards with a limiting portion to define the installation position of the spring-loaded terminal. The elastic clamping member is made of the same metal as the connector, and the connector and elastic clamping member are integrally formed. Symmetrical elastic clamping members are vertically arranged on both sides of the connector. The elastic clamping members have a concave-convex sheet-like structure, forming a cavity structure between the two elastic clamping members to accommodate and hold the connector. The elastic clamping member is a key component for achieving effective connection with the connector.

[0026] Specifically, each elastic clamping component includes an elastic support portion, a clamping portion, and a guide portion connected sequentially from bottom to top. The elastic support portion provides elastic support force for the entire elastic clamping component. The two elastic support portions extend from one end near the connector in a mutually distancing direction to form a figure-eight structure, which enhances the elastic support force. Both elastic support portions are arc-shaped elastic sheets, symmetrically arranged, with the inner surface of each arc-shaped elastic sheet having a concave arc shape convex towards the other arc-shaped elastic sheet. This concave arc structure allows the elastic support portion to deform better under stress, thus providing stable elastic support. Replaceable elastic support portions can also be wavy elastic sheets, which also provide elastic support. Rounded corners are provided between the two elastic support portions and the connector. These rounded corners prevent stress concentration and extend the service life of the elastic support portions. The clamping portion is the part that directly contacts and clamps the connecting terminal. Two clamping parts are symmetrically arranged, and the inner surface of each clamping part has a concave arc-shaped structure that bulges towards the other clamping part to form a clamping cavity that conforms to the outer contour of the connecting terminal. Both clamping parts are symmetrical concave arc-shaped structures in the vertical direction, and the distance between the highest points of the two clamping parts is equal to the distance between the lowest points of the two clamping parts. The clamping parts and the elastic support parts are connected by a planar transition to avoid stress concentration.

[0027] Reference Figure 2The concave arc-shaped structure of the two clamping parts has a radius of curvature ranging from 40-60mm. Different connecting terminals have different outer diameters, and the spring-loaded terminal in this embodiment can better adapt to the outer contours of most connecting terminals. The guide part guides the connecting terminal smoothly into the clamping cavity. The ends of the two guide parts are inclined in a direction away from each other. Furthermore, the vertical height of the axis of the concave arc-shaped structure can be adjusted by changing the angle between the guide part and the connecting member to accommodate different installation heights of the connecting terminals. The guide part is a metal sheet with a certain degree of elasticity and a smooth surface, facilitating the insertion of the connecting terminal. (Refer to...) Figure 3 The assembly steps between the spring-loaded terminal and the connecting terminal are as follows: First, weld the connector horizontally to the surface of the electronic component to ensure a secure connection. Then, press one end of the connecting terminal into the clamping cavity of the spring-loaded terminal from above along the opening between the two guides. Because the ends of the guides are inclined in opposite directions, connecting terminals of different diameters can easily approach the guides. Next, press the connecting terminal down along the guides into the clamping cavity. The elasticity of the guides will deform appropriately to adapt to the diameter of the connecting terminal, guiding it into the clamping cavity. After the connecting terminal enters the clamping cavity, the concave arc-shaped structure of the two clamping parts will tightly fit against the outer wall of the connecting terminal, achieving a wrap-around clamping of the connecting terminal. At the same time, the limiting protrusions on the inner wall of the two clamping parts near the guide end will engage with the outer periphery of the connecting terminal to prevent it from coming out. During the pressing down of the connecting terminal, the elastic support will deform under pressure, providing elastic support for the entire elastic clamping component and ensuring the stability of the clamping. Furthermore, the rounded corners between the two elastic support parts and the connector prevent stress concentration and reduce the possibility of deformation and damage to the spring terminals during assembly. In addition, after the spring terminals are mounted on the surface of the electronic components, connecting terminals can be installed onto the spring terminals using automated equipment. The implementation principle of this embodiment is as follows: the electronic component connection structure includes spring terminals and connecting terminals; vertical pressing achieves the connection between the two, improving connection versatility and spring lifespan. The spring terminal includes a metal, flat, easy-to-weld connector, and an integrally formed, concave-convex sheet-like elastic clamping component with a clamping cavity. The elastic clamping component includes, in sequence, an elastic support part that directly clamps the connecting terminal and has a concave arc-shaped inner surface with a radius of curvature and limiting protrusions suitable for multiple connecting terminals, and a guide part that guides the connecting terminal into the clamping cavity, with an inclined end, and a metal sheet-like part with an elastic and smooth surface. During assembly, the connectors are welded first, then the connectors are pressed down with the guide opening aligned with the guide. The guide guides the connectors into the clamping cavity, the clamping part wraps around and holds them, the limiting protrusion prevents them from coming out, the elastic support part provides support, and the rounded corners reduce deformation and damage.

[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
