Abstract
A rectification chip terminal structure for soldering a rectification chip on a terminal filled with a packaging material to form a secured mounting for the rectification chip is to be inserted in a coupling bore of a circuit board. The structure includes a helical buffer portion, a spacer zone containing a space, a tapered section inclining towards the center of the terminal, a bend spot having latch rings to provide coupling, and a deck having a bulged ring. The structure can prevent bending and deformation under external forces, and form a stress buffer zone to prevent the chip from being damaged and moisture from entering. It can be installed easily in the coupling bore of the circuit board and hold the packaging material securely without breaking away.
Claims5
A rectification chip terminal structure for soldering a rectification chip on a terminal filled with a packaging material to form a secured mounting for the rectification chip to be inserted in a coupling bore of a circuit board, comprising:
- a base soldering on a back side of the rectification chip;
- a root extending upwards from the base;
- a buffer portion having one end connecting to the root and a helical structure to prevent bending and deformation under external forces;
- a deck located in the rectification chip terminal for soldering the rectification chip having a bulged ring extended therefrom for coupling and preventing the packaging material from breaking away from the terminal;
- a surrounding portion surrounding a distal end of the rectification chip terminal;
- a spacer zone surrounded the periphery of the deck having a space to form a stress buffer zone and prevent moisture from entering;
- a tapered section located on the top end of the surrounding portion inclining towards the center of the rectification chip terminal to facilitate insertion and installation;
- and
- a bend spot located between the surrounding portion and the tapered section having a plurality of latch rings for coupling and preventing moisture from seeping in.
