   Connector with floating effect   

The present invention relates to a connector for soldering on a circuit board and inserting a pair of connectors, so that the connector and the circuit board are electrically connected to each other, and particularly to a connector provided with multiple terminals, such as DDR connectors, etc.

A connector is an indispensable component of an electronic component, and is used as a circuit connection component on a circuit board, especially in an operating system, such as a notebook computer or a desktop computer. Many different kinds of connectors need to be used as connection components with the circuit board, so that the components and the circuit board can be electrically connected to each other through the connector.

The connectors generally applied to the circuit board are mainly provided with a plurality of terminals for electrical conduction between the circuit board and the component inside the connector. However, when the terminals are disposed inside the connector, It is mainly electrically connected to the circuit board through two methods, one is a PIN type, and the other is an SMT type.

The installation method of the PIN type is that before the circuit board is provided with the same number of jacks as the terminals, the terminals can be inserted into the jacks and then electrically connected by soldering to achieve electrical properties. The effect of the link. Because of this type of mounting method, after a hole is drilled on the circuit board, a metal conductive layer that is the same as the terminal material is formed in the hole. The metal conductive layer is generally a copper layer in the outer coating portion of the copper layer. When there is a tin layer, when the connector is soldered to the circuit board, the tin layer is heated by a tin furnace, and the tin layers are fused to each other after high temperature melting to achieve the effect of electrical connection.

The SMT installation method does not need to drill holes in the circuit board in advance, but forms a metal conductive layer on the surface of the circuit board, and then performs high temperature welding with the surfaces of the terminals. This method can simplify the space of the circuit board, but when the connector needs to be provided with a large number of these terminals, such as DDR connectors, the flatness requirements of these terminals are quite high, and the DDR connection is required.
