The technical field relates to electrical connectors, and more particularly relates to a plug connector.
Electrical connector is a connection structure used for connecting a power supply to a device, connecting a device to another device, or connecting internal units of a device to form a circuit. The electrical connector is generally formed by a butt connector and a plug connector combined and electrically connected to each other, and the butt connector and the plug connector are electrically connected to a socket terminal and a plug terminal respectively, and the socket terminal and the plug terminal are separately formed by a fixed housing and a chip.
The related-art plug connectors mainly include an insulating housing, a plurality of conductive terminals and a locking mechanism, and the conductive terminal is installed in the insulating housing, and the locking mechanism is formed on the insulating housing and locked to or unlocked from the butt connector.
However, the plug connector has the following problems in actual use. Since the locking mechanism and the insulating housing of the plug connector are formed in one piece, and the locking mechanism is formed in the outer space of the insulating housing, the mold used to make these components is bound to be increased by a considerable extent, thereby increasing the cost of the mold. In addition, the locking mechanism is a one-piece component and has various functions such as rotation, locking, unlocking and elastic restoration, etc. As a result, the level of difficulty for the manufacture may be greatly increased. Further, due to the amount of deformation occurred during the operation of the locking mechanism, there are adverse situations such as applying insufficient or excessive force that may affect the unlocking efficiency.
In view of the aforementioned problems, the discloser proposed this disclosure based on his expert knowledge and elaborated researches to overcome the problems of the related art.
The primary objective of this disclosure is to provide a plug connector based on a separate configuration of a locking part and an actuating part, which is not only easy to manufacture, but also easy to press, operate, and unlock.
To achieve the aforementioned and other objectives, this disclosure discloses a plug connector plugged and combined with a butt connector, and the plug connector includes an insulating housing, a plurality of conductive terminals and a lock release assembly, and the insulating housing includes a main body part and a plurality of hollow plungers spaced apart from each other and extended from the main body part; each conductive terminal is contained in the insulating housing corresponding to each hollow plunger; the lock release assembly is installed on the insulating housing, and the lock release assembly includes a locking part and an actuating part separately installed with respect to the locking part, and the actuating part is arranged corresponding to the locking part and pivotally connected to the main body part, and the locking part includes a hinge connected to the main body part, a lock tab extended from the hinge, and a hook formed at an end of the lock tab away from the hinge; wherein when an action force is applied to the actuating part, the actuating part drives the locking part to rotate to unlock (or unbuckle) the hook of the lock tab from the butt connector.
This disclosure further has the following effects. By the arrangement of a restoring spring plate, the actuating part is securely fixed on the main body part.
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 insulating housing 10 includes a main body part 11 and a plurality of hollow plungers 15. The main body part 11 includes a front casing 12 and a rear casing 13. The hollow plungers 15 are spaced from each other and extended outward from an end surface of the front casing 12. Both the front casing 12 and the hollow plunger 15 are made of a desirable insulating material such as plastic. A buckle operating area 14 is defined between two adjacent hollow plungers 15 of the front casing 12. The front casing 12 has a through hole 121 formed at a position corresponding to the buckle operating area 14. An open slot 122 is formed at a position corresponding to the buckle operating area 14 and on an upper side of front casing 12. In addition, the front casing 12 has a plurality of buckle slots 123 corresponding to the hollow plungers 15 and formed at an upper side of the front casing 12. A pivot slot 124 is formed inside the front casing 12 corresponding to the buckle operating area 14.
The rear casing 13 is a cover engaged with the corresponding front casing 12 and has a wire plug hole 131 formed at a position corresponding to each of the aforementioned hollow plungers 15, and the wire plug hole 131 is provided for inserting a wire (not shown in the figures). In addition, a via 132 is formed between two adjacent wire plug holes 131 and communicating with the through hole 121, and the rear casing 13 has a buckle 133 formed at an upper side of the rear casing 13 corresponding to each wire plug hole 131. Each buckle 133 is buckled and connected to each buckle slot 123.
Each conductive terminal 20 is accommodated in the front casing 12 and the hollow plunger 15 of the insulating housing 10 corresponding to each hollow plunger 15, and each conductive terminal 20 mainly includes a wire clamp 21 and a pin clamp 22 connected to the wire clamp 21. The wire clamp 21 is arranged corresponding to the wire plug hole 131, and the pin clamp 22 is extended into the hollow plunger 15.
The lock release assembly 30 is installed on the insulating housing 10, and mainly includes a locking part 31 and an actuating part 32 separately installed with respect to the locking part 31. The locking part 31 and the front casing 12 of the main body part 11 are formed in one piece (or integrally formed) and disposed above the buckle operating area 14. The locking part 31 mainly includes a hinge 311 connected to the front casing 12 and a lock tab 312 horizontally extended from the hinge 311. A hook 3121 is formed at an end of the lock tab 312 away from the hinge 311.
The actuating part 32 is arranged corresponding to the locking part 31 and pivotally connected to the front casing 12 of the main body part 11. The actuating part 32 mainly includes a force arm 321, a restoring spring plate 322 extended backward from the force arm 321, a pivot 323 extended from the left-side or right-side of the force arm 321, a stand 324 extended upward from the junction of the force arm 321 and the restoring spring plate 322, and a press handle 325 extended from the stand 324. The force arm 321, the restoring spring plate 322 and the pivot 323 are installed in the main body part 11. The stand 324 passes through the open slot 122 of the front casing 12. The press handle 325 is formed outside the main body part 11. The pivot 323 is pivotally connected to the pivot slot 124. An end of the force arm 321 away from the pivot 323 abuts against and is connected to the lower surface of the lock tab 312. The restoring spring plate 322 mainly includes a curved plate 3221 and a cylinder 3222 formed at an end of the curved plate 3221. The force arm 321 and the curved plate 3221 are spanned between the front casing 12 and rear casing 13. The force arm 321 and the cylinder 3222 abut against and are connected to the interior of the front casing 12 and the interior of the rear casing 13 respectively.
