Description

Technical Field

[0001] This utility model relates to the field of diode technology, specifically a TVS / ESD protector assembly. Background Technology

[0002] ESD diodes, also known as electrostatic discharge protection diodes, are devices used to protect electronic components from electrostatic discharge (ESD) damage. TVS diodes, also known as transient voltage suppressor diodes, are a new type of high-efficiency circuit protection device developed from Zener diode technology. Both TVS and ESD protection devices are characterized by rapid response and high integration. In practical applications, if a soldering error occurs during the soldering of TVS / ESD protection device leads, the leads need to be disassembled. During disassembly, the leads are easily damaged or broken, affecting subsequent soldering and potentially rendering the TVS / ESD protection device unusable. To solve these problems, this invention provides a TVS / ESD protector assembly. Utility Model Content

Pins are soldered to the upper and lower ends of the chip body, and the two pins are located at the left and right ends of the package. Connection slots are symmetrically formed at the left and right ends of the package. The ends of the pins extend out of the connection slots, and connection feet are matched and installed in the connection slots. The upper surface of the connection feet contacts the pins. First, one end of the connection foot is matched and installed in the connection slot, and then the other end of the connection foot is soldered to the electronic board. After checking that there are no errors, the connection foot and the pin are soldered together.

[0005] Preferably, the connecting pin is Z-shaped; the lower horizontal section of the Z-shaped connecting pin is soldered to the electronic board.

[0006] Preferably, the upper horizontal portion of the connecting foot contacts the pin, and the upper horizontal portion of the connecting foot is fitted into the connecting groove; the connecting foot and the pin are connected by soldering to improve connection stability.

[0007] Preferably, the pin and the inner wall of the connecting groove form a U-shaped groove, and a slot is opened on the upper surface of the upper horizontal part of the connecting foot, so that the cross-section of the upper horizontal part of the connecting foot is U-shaped, and the upper horizontal part of the connecting foot is fitted into the connecting groove.

[0008] Preferably, the pins are matched and installed inside the slot; this increases the welding area between the pins and the connecting feet, thereby improving connection stability.

[0009] The beneficial effects of this utility model are as follows:

[0010] After the lower horizontal section of the connector pin matches the connector slot, the lower horizontal section of the connector pin is then soldered onto the electronic board. Finally, the upper horizontal section of the connector pin is soldered to the pin. Even if the engineer solders the connector pin incorrectly, the connector pin can be removed. Even if it is damaged, it will not affect the soldering and use of the chip body. Attached Figure Description
