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.

The plug electrical connector 1, the insulating body 10, the side wall 100, the end wall 102, the docking space 104, the stopper 106, the plug terminal 12, the plug power terminal 14, the soldering portion 140, the first extension portion 142, the second extension portion 144, and the contact portion 146.

Detailed Description

Please refer to fig. 1, fig. 2 and fig. 3, which are a schematic perspective view, a schematic top view and a schematic exploded perspective view of the present invention. Referring to fig. 4, it is a schematic view of the three-dimensional structure of the plug power terminal of the present invention. The utility model relates to a board is to board plug electric connector, plug electric connector 1 mainly includes insulator 10, plural number plug terminal 12 and a pair of plug power supply terminal 14, wherein insulator 10 includes a pair of lateral wall 100 and a pair of end wall 102, each lateral wall 100 and each end wall 102 enclose into a butt joint space 104, each plug terminal 12 sets up in each lateral wall 100, each plug power supply terminal 14 sets up respectively in end wall 102, wherein plug power supply terminal 14 is defined there is welding part 140, first extension 142, second extension 144 and contact site 146, welding part 140 is located insulator 10 bottom, first extension 142 is extended and is sheltered from end wall 102 lateral surface by welding part 140, second extension 144 is extended and is sheltered from end wall 102 top surface by first extension 142, contact site 146 is extended and is sheltered from each lateral wall 100 outer wall surface by second extension 144 both ends.

The welding portion 146 and the first extension portion 142 are L-shaped, the first extension portion 142 and the second extension portion 144 are L-shaped, and the second extension portion 144 and the contact portion 146 are L-shaped, so that the structure at both ends of the insulating body 10 can be effectively covered by the plug power terminal 14 by using the L-shaped structure, and therefore, when the plug electrical connector 1 is inserted into the corresponding female connector, the metal structure of the plug power terminal 14 can prevent the insulating body 10 (plastic structure) of the plug electrical connector 1 from being damaged due to impact or friction.

Furthermore, the width of the contact portion 146 is larger than the width of the plug terminal 12, and the structural area of the plug power terminal 14 is large, so that not only can the current output stability be ensured, but also the ultra-large current transmission is satisfied, and the heat generated by the element is small, so that the plug power terminal is used for fast and regular charging and the like.

Since the position of the contact portion 146 corresponds to the position of the soldering portion 140, and the sidewall 100 of the insulating body 10 extends outward to form a stopper 106 between the contact portion 146 and the soldering portion 140, the stopper 106 can separate the contact portion 146 from the soldering portion 140 to prevent short circuit.

More specifically, the plug power terminal 14 may be replaced with a material according to the requirement, and a material for transmitting a large current (3A to 5A, 3A to 10A) or a signal source is selected. In addition, the soldering portion 140 is used for being soldered on a circuit board.
