Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of charging springs, in particular to an inserted SMT patch clamping contact plane spring. Background Art
[0002] The current electronics manufacturing industry, particularly in the field of surface mount technology (SMT), places increasing demands on reliable connections between electronic components and printed circuit boards (PCBs). Traditional SMT patch connections often rely on the strength of solder joints to ensure connection stability. However, in applications that require frequent plugging and unplugging or withstand significant external forces, such as charging ports, a single solder connection often fails to meet long-term requirements. In particular, ensuring a secure yet easily pluggable connection between charger terminals and PCBs presents a pressing challenge.
[0003] Traditional connector designs often suffer from shortcomings such as uneven clamping force, small contact area, and easy loosening. This not only affects charging efficiency but can also lead to serious consequences such as poor contact, short circuits, and even device damage. Therefore, the market is in urgent need of a new SMT patch clamping contact structure that can provide stronger clamping force and more stable contact performance while ensuring stable welding. Utility Model Content
[0004] In view of the deficiencies of the prior art, the present invention provides an insertable SMT patch clamping contact plane spring, which solves the problems raised by the above-mentioned background technology.
[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: an inserted SMT patch clamping contact plane spring, including a spring body, a plug-in hole position is reserved inside the spring body, and a plurality of clamping springs are extended and bent inside the plug-in hole position, and the plurality of clamping springs are located inside the plug-in hole position and are distributed in a triangular shape as a whole.
[0006] Furthermore, the plugging hole is located at the center of the spring body, and the plugging hole is set to a circular hole structure.
[0007] Furthermore, the clamping spring is provided with a downwardly inclined arc at the plug-in hole.
[0008] Furthermore, the adjacent ends of each of the clamping springs are inclined downward, and the downward inclination angle is 30°.
[0009] Furthermore, an adsorption portion extends outward from the tail end of the spring body, and the adsorption portion is configured as a planar structure.
[0010] Furthermore, the tail end of the spring body and both sides of the adsorption portion extend outward to form an insertion angle, and the bottom ends of the insertion angle are bent downward by 90 degrees.
[0011] The utility model provides an insertable SMT patch clamping contact plane spring. Compared with the existing technology, it has the following advantages:
[0012] 1. Enhanced Clamping Stability: A circular hole is positioned at the center of the spring body, and a triangular-shaped spring is bent inside to form a triangular clamping contact point. This design not only increases the contact area with the charger terminal, but also significantly improves the clamping force through the stable triangular structure, effectively preventing the terminal from loosening and falling off during insertion and removal.
[0013] 2. Convenient welding and installation: The angled design extending outward from the tail end of the shrapnel body, combined with the reserved holes on the PCB board, makes the welding and installation process more convenient and quick, while also improving the accuracy and stability of welding.
[0014] 3. Optimized contact performance: Each clamping spring is tilted downward by 30°. This design allows the charger terminal to enter the clamping area more smoothly when inserted, while reducing contact resistance and improving charging efficiency.
[0015] In summary, the plug-in SMT patch clamping contact flat spring, on the basis of ensuring stable welding, realizes stable clamping and efficient contact of the charger terminal through a unique clamping structure design. BRIEF DESCRIPTION OF THE DRAWINGS
