[0025] In one embodiment, the first latch plate 1311 has two opposing interference portions 13113. When the latch member 131 is disposed in the latch receiving groove 121, the two interference portions 13113 of the first latch plate 1311 interfere with two opposing side walls of the latch receiving groove 121 to fix the first latch plate 1311 in the latch receiving groove 121.

[0026] In one embodiment, the latch receiving groove 121 further has a second latch positioning portion 1213, which is close to the plug-in component 10 protruding from the plug-in surface 12a. When the latch 131 is disposed in the latch receiving groove 121, the bent connecting piece 1313 of the latch 131 is located in the second latch positioning portion 1213. In other words, the second latch positioning portion 1213 positions the bent connecting piece 1313 at the position of the latch receiving groove 121.

[0027] In one embodiment, the first latching piece 1311 has a drawstring through hole 13114, which is located at one end of the first latching piece 1311 away from the bent connecting piece 1313, and the second latching piece 1312 has a drawstring fixing portion 13122, which is located at one end of the second latching piece 1312 away from the bent connecting piece 1313.

After the other end of the drawstring 132 passes through the drawstring through hole 13114, the other end of the drawstring 132 enters the drawstring clearance gap 1214 and passes through the latch receiving groove 121 from the drawstring clearance gap 1214, thereby preventing the drawstring 132 from being clamped between the bottom surface of the latch receiving groove 121 and the first latch plate 1311, so that the drawstring 132 can be pulled smoothly.

[0029] In one embodiment, the first latch plate 1311 has an anti-friction member 13115, which is disposed on the side of the drawstring perforation 13114 away from the plug-in surface 12a and is located between the first latch plate 1311 and the second latch plate 1312. The surface of the anti-friction member 13115 facing the drawstring perforation 13114 is an arc surface, and the drawstring 132 rests on the surface of the anti-friction member 13115 facing the drawstring perforation 13114, thereby effectively reducing the chance of the drawstring 132 breaking due to friction during the pulling process.

[0030] In one embodiment, when unlocking is performed by the pull strap 132, the pull strap 132 is pulled and allowed to move smoothly under the guidance of the arc surface of the anti-friction member 13115, and the pull strap fixing portion 13122 is driven by the pull strap 132 to move downward, causing the height of the buckle protrusion 13121 to drop, thereby unlocking the second latch plate 1312 from the buckle hole 21 of the board-end connector 2, and then continuing to pull the pull strap 132 to disengage the line-end connector 1 and the board-end connector 2 from each other.

[0031] In summary, the present application provides a wire-end connector, which achieves a two-way fastening effect by fastening the snap spring of the first latch piece with the snap hole of the insulating body and the snap convex portion of the second latch piece with the board-end connector, thereby increasing the connection stability of the latch assembly. In addition, by providing two positioning protrusions on the plug-in surface that docks with the board-end connector, and the two positioning protrusions are located inside the side of the plug-in surface, the area where the wire-end connector docks with the board-end connector is maintained within the area of ​​the plug-in surface of the insulating body, thereby avoiding increasing the volume of the wire-end connector.
