Description

Power connector

This creation is about an electrical connector, especially a power connector.

In the daily life, various electronic products require power supply for operation. Therefore, a general electronic device is usually provided with a power connector for plugging the power plug into the power connector to supply power through the commercial power.

For example, in the patent No. M408859 filed by the Republic of China, it discloses a power connector including a socket housing and a grounding terminal and a power terminal housed in the socket housing. Wherein, the grounding terminal and the power terminal respectively have a plurality of claw contact portions, and the multi-claw design can improve the stability of the terminal contact when the socket is connected.

The multi-claw structure of the ground terminal and the power terminal of the above patent can increase the stability of the contact of the terminal. However, when the power connector is connected to the plug, since the multi-claw designed terminal is in point contact with the plug, it is impossible to provide a comprehensive electrical connection and reduce the guiding effect.

In view of this, in order to achieve the above objectives, the creator has devoted himself to researching and cooperating with the application of theory, and finally proposed a creation that is reasonable in design and effective in improving the above-mentioned defects.

One of the aims of the present invention is to provide a power connector to provide good electrical continuity and to maintain the elastic force that the contact piece should have.

In order to achieve the above object, the present invention is a power connector including a socket, a pair of first terminals, and a pair of second terminals. The socket comprises a housing and a cylinder formed in the housing, wherein the opposite inner side walls of the housing are respectively provided with a first recess, and the opposite outer sidewalls of the cylinder are respectively provided with a second recess, the first terminal respectively Correspondingly coupled in the first recess, each of the first terminals includes a first clamping piece disposed parallel to the inner side wall and a first contact piece that is retracted from the front side of the first clamping piece and extends forward, and the second terminal is respectively coupled In the second recess, each of the second terminals includes a second clamping tab disposed parallel to the outer sidewall and a second contact tab that is retracted from the front side of the second clamping tab and extends forward.

Compared with the prior art, the terminal structure of the power connector of the present invention includes a contact piece for bonding and a contact piece for electrically guiding. Since the contact piece is a piece, the contact piece is contracted from the front side of the clamping piece and extends forward, and maintains the elastic force of the contact piece. Therefore, when the power connector of the present invention is connected to the external plug, the contact between the contact piece and the external plug is a line contact, thereby replacing the traditional multi-claw type terminal in a point contact manner to achieve a good electrical connection. Increase the practicality of this creation.
