Description

Board-to-board plug electric connector

Technical Field

The utility model relates to a board is to board plug electric connector.

Background

As the size and weight of 3C electronic products are becoming smaller and lighter, electrical connection between different circuit boards is often required in the portable electronic device, and because the electronic device has a small size and the internal space is still relatively narrow, the circuit boards are usually electrically connected to each other by Board-to-Board (BTB) electrical connectors, so as to achieve better space utilization.

When the board-to-board connector assembly requires a relatively large current, the terminal structures at the two ends of the board-to-board connector assembly are the same as those of the signal terminals, so that the board-to-board connector assembly cannot bear a high amperage current.

Preferably, the first contact portion width is greater than the plug terminal width.

Preferably, the second contact portion width is greater than the plug terminal width.

Preferably, the third contact portion width is greater than the plug terminal width.

Preferably, the first contact portion of the first power terminal and the third contact portion of the second power terminal are in corresponding positions.
