Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and more specifically, to a spring pin connector. Background Art

[0002] Connectors are basic components of electronic products and industrial products. Their main function is to build a bridge of communication between blocked or isolated circuits within a circuit, so that the circuit can flow and transmit current or signals.

[0003] In recent years, along with the sustained and rapid growth of my country's economy, the rapid development of high-tech intelligence has been driven. Various connector strategies have been continuously innovated to meet customer communication purposes such as control and transmission. In order to further enhance customer experience, a spring pin connector was born after the USB plug-in connector. It is mainly used in precision connectors in electronic products and widely used in semiconductor equipment. The spring pin connector is divided into a male socket and a female socket. The male socket generally integrates multiple spring pins arranged in one or two rows. The female socket is generally integrated on the PCB board. There are multiple small circular copper rings as contact points, which correspond to the spring pins of the male socket one by one. When the male and female sockets are connected, each spring pin is connected to a copper ring. Through the compression of the spring pin, it effectively overlaps with the female socket to achieve signal conduction, which can support the stable passage of large currents.

[0004] In actual use, there are several inconveniences in using universal connectors: ① Each time the connector is connected, it needs to be aligned. For example, the most commonly used USB Type A connector can only be inserted and connected in one direction. The USB Type C connector commonly used in upgraded mobile phones can only be inserted and connected in two directions, but it has greatly improved the user experience; ② For ordinary connectors, the circuit connection is not backed up. When one of the connections is loose or disconnected, the connector will become unusable. Utility Model Content
