[0032] The following specific implementation manner will further illustrate the present invention in conjunction with the above-mentioned drawings. [Specific implementation method]

[0033] like Figure 1-9As shown, a plug connector 100 in accordance with the present invention is used for locking with a socket connector. The plug connector 100 includes an insulating body 1, an inner film 4 accommodated in the insulating body 1, a circuit board 2 partially covered by the inner film 4, a cable 3 electrically connected to the circuit board 2, a plurality of springs 5 ​​accommodated in the insulating body 1 and a locking mechanism 6 cooperating with the springs 5.

[0034] The insulating body 1 includes an upper shell 11 and a lower shell 12 assembled with the upper shell 11. The upper shell 11 includes an upper wall 111 and a pair of upper side walls 112 located on the left and right sides of the upper wall 111. The upper wall 111 includes a square hole 1111 and through holes 1112 located on both sides of the square hole 1111. The upper side walls 112 are respectively provided with side holes 1121. The lower shell 12 includes a front wall 121, a bottom wall 122 opposite to the front wall 121, and a pair of lower side walls 123 located on the left and right sides of the front wall 121. The front wall 121 includes an opening 1211 for the circuit board 3 to pass through. The lower side walls 123 are respectively provided with protrusions 1231 that cooperate with the side holes 1121.

[0035] The circuit board 2 is partially enclosed in the insulating body 1 , and includes an insertion portion 21 extending from the opening 1211 and a plurality of first holes 22 corresponding to the springs 5 ​​. A plurality of metal sheets 211 are disposed on the upper and lower surfaces of the insertion portion 21 .

[0036] The front ends of the cables 3 are respectively welded to the upper and lower surfaces of the circuit board 2 , and the rear ends extend backwards out of the insulating body 1 .

[0037] The inner film 4 is coated on the connection between the circuit board 2 and the cable 3 , and includes a boss 41 for clamping the locking mechanism 6 and a plurality of second holes 42 corresponding to the springs 5 ​​.

[0038] The locking mechanism 6 includes a pressing portion 61 passing through the square hole 1111 and protruding out of the insulating body 1, and locking portions 62 extending from both ends of the pressing portion 61 in the horizontal direction, and the pressing portion 61 and the locking portion 62 are integrally formed. The locking portion 62 includes a horizontal portion 621, a vertical portion 622 extending upward from the horizontal portion 621, a bending portion 623 connected to the vertical portion 622, and a snap portion 624 extending upward from the insulating body 1 from the bending portion 623. The snap portion 624 extends upward from the corresponding through hole 1112 to lock with the socket connector. The locking mechanism 6 also includes a plurality of columns 63 located below the pressing portion 61, and the springs 5 ​​are respectively sleeved on the corresponding columns 63. The columns 63 pass through the first hole 22 and the second hole 22 to abut against the lower shell 12.

[0039] When the plug connector 100 is mated with the socket connector, the plug connector 100 is inserted forward into the opening of the socket connector until the metal sheet 211 of the circuit board 2 is electrically connected to the conductive terminal of the socket connector, and at the same time, the snap portion 624 of the locking mechanism 6 protrudes into the locking hole of the socket connector. When the plug connector 100 is unlocked from the socket connector, an external force presses the pressing portion 61 downward, causing the spring to be compressed and the entire locking mechanism 6 to move downward until the snap portion 624 is accommodated in the insulating body 1, thereby withdrawing from the locking hole of the socket connector, and releasing the lock between the plug connector 100 and the socket connector. When the external force is removed, under the action of the elastic restoring force of the spring 5 itself, the locking mechanism 6 moves upward, and the snap portion 624 passes through the through hole 1112 and returns to its original position.

[0040] The above are only some of the preferred embodiments of the present invention. Any equivalent changes made to the technical solution of the present invention by ordinary technicians in this field after reading the specification of the present invention are covered by the claims of the present invention.
