Description of Related Art

A related-art electric connector is used for connecting a power source and a device, connecting a device and a device or connecting internal units of a device to establish an electric connecting structure. The electric connector may be consisted of a plug connector and a socket connector being electrically connected. The socket connector and the plug connector are electrically connected through socket terminals and plug terminals, and the socket terminals and the plug terminals are respectively disposed and fastened on a housing and a chip.

The related-art plug connector mainly has an insulation housing, a plurality of electric conductive terminals and a locking mechanism. The electric conductive terminals are disposed in the insulation housing, the locking mechanism is formed on the insulation housing to make a socket connector be mutually locked or unlocked.

However, there are some problems when the plug connector is in actual operations. Because the locking mechanism and the insulation housing are formed in one piece, and the locking mechanism is disposed at an external space of the insulation housing, a mold used for manufacturing the above-mentioned components has to be greatly enlarged and the production cost of the mold is increased. Moreover, the locking mechanism is a single-piece component and provided with various functions such as rotating, locking, unlocking and elastically recovering, thus the manufacturing difficulty is greatly increased. During the process of the locking mechanism being operated, various poor situations, such as being not enough or over may happen when the deforming degree of the locking mechanism being rotated, thus the unlocking and unbuckling performance is lowered.

Accordingly, the applicant of the present disclosure has devoted himself for improving the mentioned shortages.

SUMMARY OF THE DISCLOSURE

The present disclosure is to provide a plug connector, in which a locking part and an actuating part are separately disposed, thus the manufacturing process is easy, the pressing operation is convenient and the unbuckling operation is simplified.

Accordingly, the present disclosure provides a plug connector, which is inserted to and combined with a socket connector, and includes an insulation housing, a plurality of electric conductive terminals and an unlocking assembly. The insulation housing has a main body part and a plurality of hollow columnar plugging members, the hollow columnar plugging members are spaced with intervals and extended from the main body part. Each of the electric conductive terminals is disposed in the insulation housing corresponding to each of the hollow columnar plugging members. The unlocking assembly is disposed on the insulation housing and has a locking part and an actuating part separately arranged relative to the locking part. The actuating part is disposed corresponding to the locking part. The locking part has a pivotal part connected to the main body part, a locking piece extended from the pivotal part and a force applying arm extended from the pivotal part towards a direction opposite to the locking piece. A latching hook is formed at one end of locking piece away from the pivotal part. An external force is applied to the actuating part, the actuating part drives the locking part to rotate to make the latching hook of the locking piece and the socket connector be unbuckled.

Advantages achieved by the present disclosure are as follows. With a recovering elastic sheet being disposed, a latching action force between the latching hook of the locking part and a locking edge of the socket connector may be increased. With longitudinal moving of the actuating part, the operation of the locking part may be more stable and accurate.
