Embodiment Construction

[0017] The specific implementation manner of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings.

[0018] Such as figure 1 As shown, a plug-in connection structure between a circuit board and a housing, including a plug-in terminal 1 and a circuit board 3, both of which are provided with pads, and between the plug-in terminal 1 and the circuit board 3 through a binding wire 2. Bind and connect the pad 4 on the plug-in terminal to the pad on the circuit board.

[0019] Preferably, the pad is a gold-plated or silver-plated disk, which is less affected by temperature changes and has good connection stability. There is gel on the outside of the binding wire between the plug-in terminal and the circuit board to avoid the oxidation of the binding wire, which has the function of corrosion resistance and buffering external impact, and the connection is firm and stable.

[0020] In order to achieve...

Abstract

The invention discloses a connection structure and connection method for a circuit board and a casing plug-in piece. The connection structure comprises a plug-in terminal and the circuit board, pads are arranged on the plug-in terminal and the circuit board respectively, and the pad on the plug-in terminal and the pad on the circuit board are bonded and connected through a binding line between the casing plug-in piece and the circuit board. Therefore, the binding line has strong shock resistance and anti-vibration performance and has excellent high-and-low temperature resistance. Oxidation of the binding line is avoided through glue filling and solidification, the connection structure has effects of resisting to corrosion and buffering external impacts, and connection is firm and stable.

Description

technical field [0001] The invention relates to the technical field of electrical connection, in particular to a connection structure and connection method between a circuit board and a casing plug-in. Background technique [0002] The electrical connection between the circuit board inside the electronic product and the plug-in terminal of the housing is usually connected by soldering. Specifically, holes are made on the circuit board, and the terminals of the connector are inserted and then welded to realize electrical connection, or a soft board is used to weld the circuit board and the terminals of the connector respectively to realize electrical connection. [0003] The traditional solder connection structure has little impact on civilian electronic products, but it has defects in automotive electronic components and high-end industrial electronic products. The product is used in the case of large and frequent changes in high and low temperatures. Due to the inconsisten...
