The present disclosure relates to an electric connector, especially to a plug connector.
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.
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.
The features of the disclosure believed to be novel are set forth with particularity in the appended claims. The disclosure itself, however, may be best understood by reference to the following detailed description of the disclosure, which describes a number of exemplary embodiments of the disclosure, taken in conjunction with the accompanying drawings, in which:
The technical contents of this disclosure will become apparent with the detailed description of embodiments accompanied with the illustration of related drawings as follows. It is intended that the embodiments and drawings disclosed herein are to be considered illustrative rather than restrictive.

The insulation housing 10 mainly has a main body part 11 and a plurality of hollow columnar plugging members 15. The main body part 11 has a front shell cap 12 and a rear shell cover 13. The hollow columnar plugging members 15 are spaced with intervals and extended from a distal surface of the front shell cap 12. The front shell cap 12 and each of the hollow columnar plugging members 15 are made of a material having a desirable insulating property, for example a plastic material. A buckle operating zone 14 is formed between the two adjacent hollow columnar plugging members 15 of the front shell cap 12. A penetrated hole 121 is formed on the front shell cap 12 at a location corresponding to the buckle operating zone 14, and an opened slot 122 corresponding to the buckle operating zone 14 is formed at an upper location of the front shell cap 12. Moreover, a buckle slot 123 corresponding to each of the hollow columnar plugging members 15 is formed at a top end of the front shell cap 12.
The rear shell cover 13 is correspondingly engaged with the front shell cap 12, and a wire inserting hole 131 is formed corresponding to each of the hollow columnar plugging members 15. The wire inserting hole 131 allows a conductive wire (not shown in figures) to be inserted. A through hole 132 communicating with the penetrated hole 121 is formed between every two of the wire inserting holes 131. Moreover, a buckle block 133 is formed at the top end of the rear shell cover 13 and arranged corresponding to each of the wire inserting holes 131. Each of the buckle blocks 133 is mutually buckled and fastened with each of the buckle slots 123.
Each of the electric conductive terminals 20 is accommodated in the front shell cap 12 of the insulation housing 10 and the hollow columnar plugging member 15, and is arranged corresponding to each of the hollow columnar plugging members 15. Each of the electric conductive terminals 20 mainly has a conductive wire clipping part 21 and a pin clipping part 22 connected to the conductive wire clipping part 21. The conductive wire clipping part 21 is disposed corresponding to the wire inserting hole 131, and the pin clipping part 22 is extended into hollow columnar plugging member 15.
The unlocking assembly 30 is disposed on the insulation housing 10, and mainly has a locking part 31 and an actuating part 32 separately arranged relative to the locking part 31. The locking part 31 and the front shell cap 12 of the main body part 11 are formed in a one piece (or integrally formed), and the locking part 31 is located above the buckle operating zone 14. The locking part 31 mainly has a pivotal part 311 connected to the front shell cap 12, a locking piece 312 horizontally extended from the pivotal part 311 and a force applying arm 313 horizontally extended from the pivotal part 311 towards a direction opposite to the locking piece 312. One end of the locking piece 312 away from the pivotal part 311 is formed with a latching hook 3121.
The actuating part 32 is disposed corresponding to the locking part 31. The actuating part 32 mainly has a recovering elastic sheet 321, a supporting frame 322 longitudinally extended along a central location of the recovering elastic sheet 321 and a pressing handle 323 extended from the supporting frame 322. The recovering elastic sheet 321 is disposed in the main body part 11. The supporting frame 322 passes through the opened slot 122 of the front shell cap 12. The pressing handle 323 is disposed at an outer side of the main body part 11. The recovering elastic sheet 321 mainly has an arched plate 3211 and a circular column 3212 disposed at two ends of the arched plate 3211. The arched plate 3211 is crossly arranged between the front shell cap 12 and the rear shell cover 13. Each of the circular columns 3212 respectively abuts against inside the front shell cap 12 and the rear shell cover 13. A mounting port 324 is formed at a joint location where the arched plate 3211 is connected to the supporting frame 322. The mounting port 324 allows the force applying arm 313 to be accommodated. Moreover, a stopping block 325 is disposed at a top end of the mounting port 324 of the supporting frame 322 and used for limiting (restricting) a moving stroke of the actuating part 32.
