Description

Charging contact structure and electronic product

Technical Field

The utility model relates to a charging contact structure for an electronic product and the electronic product using the structure.

Background

In the current electronic products, the charging contact mode mainly comprises a POGOPIN mode and a spot welding mode.

POGOPIN is a precision connector applied to electronic products such as mobile phones and the like, is widely applied to semiconductor equipment and plays a role in connection. The POGOPIN has different appearances according to different applications, but the POGOPIN has a precise spring structure inside as a whole. The surface of the product is generally plated with gold, and springs are also plated with gold when the process is required.

The thimble realizes circular telegram or switches on, and most passes through the slant below and contacts with the copper wall, and the spring bears a small amount, consequently requires that the copper sheathing inner wall is smooth. The electrical characteristics will actively find the path with the smallest resistance to conduct the current. If the POGOPIN factory is made into a non-oblique plane, but the bottom is flat, most of current needs to be conducted through the spring completely, and the requirement on the spring is high.

The POGOPIN is a spring type probe formed by riveting and prepressing three basic components of a needle shaft, a spring and a needle tube through a precision instrument, and a precise spring structure is arranged in the POGOPIN. The surface coating of POGOPIN is generally gold-plated, so that the corrosion resistance, mechanical property, electrical property and the like of the POGOPIN can be better improved. The needle point is provided with a sharp needle, a grasping needle, a round-head needle, a knife-shaped needle and the like. The POGOPIN is generally applied to precise connection in electronic products such as mobile phones, portable electronic equipment, communication, automobiles, medical treatment, aerospace and the like, and can improve the corrosion resistance, stability and durability of the connectors. Because POGOPIN is a very fine probe, the weight and the volume of the appearance of the connector can be reduced when the POGOPIN is applied to a precise connector, and the connector can be more fine and beautiful.

At present, the integration level of electronic products is higher and higher, the requirement on space is stricter and tighter, and the POGOPIN mode occupies higher space height and cannot adapt to the requirement; the spot welding method can solve the problem of space, but cannot be repeatedly attached and detached.
