Therefore, high power signal transmission is achieved.

2. Description of Related Art

Connectors are common electrical components of electronic devices. Different electronic devices are connected to each other by connectors so that signal transmission is implemented between different electronic devices to further incorporate these electronic devices into a specific electronic system.

The semiconductor industries are rapidly developed in recent years so that electronic devices have high-speed and high-performance built-in processing chips to fulfill user's demand. Also, the connectors of the electronic devices need to cooperate with the processing chips to transmit high power signals. However, conventional connectors cannot afford transmission high power signals so that the connector manufacturers constantly develop new high power connectors.

To overcome the shortcomings, the present invention provides a high power receptacle connector to mitigate or obviate the aforementioned problems.

The main objective of the invention is to provide a high power receptacle connector that improves contacting capability with other connectors connected thereto and prevents power/signal transmission failure or unusual increase of the resistance. Therefore, high power signal transmission is achieved.

A high power receptacle connector in accordance with the present invention comprises a first insulating housing, a second insulating housing, a first terminal, a second terminal, a third terminal and a shell. The second insulating housing is mounted on the first insulating housing and has a cylinder. The first terminal is cylindrical, surrounds the cylinder and has multiple first resilient contacting tabs and a reinforcing ring formed on front ends of the first resilient contacting tabs. The second terminal is cylindrical and mounted around the cylinder and has multiple radially protruding second resilient contacting tabs. The second resilient contacting tabs increase the contacting areas, reduce the resistance of the terminals and further improve the power of the high power receptacle connector and stably hold an external plug connector.

Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
