[0028] The female end 2 includes a second housing 201 , and a wedge block 202 is fixedly connected to the top of the second housing 201 .

[0029] like Figure 1-Figure 5As shown, the female end 2 also includes pins 203, a jack 204 and a female terminal 205. Several pins 203 are fixedly connected to one side of the shell 201, and a jack 204 is opened inside the shell 201, and the inside of the jack 204 is fixedly connected to the female terminal 205.

[0030] The male end 1 also includes an insert block 110, a male terminal 111 and a cable 112. One side of the shell 101 is fixedly connected to several insert blocks 110, the inside of the insert block 110 is fixedly connected to the male terminal 111, and the other side of the shell 101 is fixedly connected to the cable 112.

[0031] The pin 203 of the female end 2 is connected to the female terminal 205, and the pin 203 is connected to the circuit board by welding, so that the entire female end 2 is connected to the circuit board. By aligning the plug 110 with the socket 204 and inserting it, the male terminal 111 is connected to the female terminal 205, and the male terminal 111 is connected to the flat cable 112, thus realizing the connection between the board and the wire.

[0032] like Figure 7 As shown, the front end of the male terminal 111 has four arc-shaped pieces 1110 , and the male terminal 111 and the flat cable 112 are connected to each other.

[0033] During the process of inserting the plug 110 into the socket 204, the arc-shaped piece 1110 enables the female terminal 205 to be smoothly inserted into the male terminal 111, and the male terminal 111 and the female terminal 205 are in contact on all four sides after being connected, which is beneficial to reducing the contact impedance and improving the signal or current transmission quality between the wire and the board.

[0034] like Figure 1-Figure 3 As shown, the lock buckle 105 and the wedge block 202 are engaged with each other, and the fixing block 109 is fixedly connected to the upper surface of the shell 101.

[0035] The arc-shaped spring piece 106 is connected to the lower surface of the fastening plate 104 by screws, and the outer surface of the sliding rod 108 is slidably connected to the two sliding blocks 107.

[0036] By connecting the male end 1 and the female end 2, the lock buckle 105 will be slightly lifted after encountering the wedge block 202 during this process, and then the lock buckle 105 will be buckled with the wedge block 202, so that the male end 1 and the female end 2 will be firmly connected. Since the arc-shaped spring piece 106 has an upward resistance force on the buckling plate 104, the cooperation of the shaft 103 and the triangular block 102 can make the lock buckle 105 maintain a downward resistance force. In this way, even in a vibrating environment, the lock buckle 105 can still remain buckled with the wedge block 202, thereby maintaining the connectivity between the male end 1 and the female end 2. It can protect the wire-to-board connector and prevent it from loosening. When the male end 1 and the female end 2 need to be separated, by pressing the upper surface of the snap-fit ​​plate 104, the arc-shaped spring piece 106 is deformed after being subjected to force, so that its two ends drive the slider 107 to slide on the slide rod 108, so that the lock 105 can be disengaged from the wedge block 202, and then the male end 1 is pulled to make the plug 110 disengage from the socket 204, so that the male end 1 is disconnected from the female end 2. The overall structure ensures the connection strength of the wire-to-board connector while facilitating the plugging and unplugging separation of the male end 1 and the female end 2.

[0037] like Figure 2 As shown, anti-slip grooves are provided on both sides of the housing 101 , and an arc-shaped groove is provided on the upper surface of the fastening plate 104 .

[0038] By setting anti-slip grooves on both sides of the shell 101, the friction with the fingers is increased, making insertion and removal easier. By setting an arc-shaped groove on the top of the snap plate 104, it is easy to fit the fingers and prevent slipping when pressing the snap plate 104.

[0039] Working principle: pinch the two sides of the shell 101, then align the plug 110 with the socket 204 and insert it, so that the male terminal 111 and the female terminal 205 are connected, and in the process of connection, the lock 105 will be slightly lifted after encountering the wedge 202, and then the lock 105 and the wedge 202 are buckled together, so that the male end 1 and the female end 1 will be firmly connected. Since the arc-shaped spring piece 106 has an upward resistance to the buckling plate 104, the shaft 103 and the triangular block 102 can cooperate to make The lock buckle 105 maintains a downward resistance force, so that the lock buckle 105 can still remain engaged with the wedge block 202 even in a vibrating environment; when the male end 1 and the female end 2 need to be separated, by pressing the upper surface of the locking plate 104, the arc-shaped spring piece 106 is deformed after being subjected to the force, and its two ends drive the slider 107 to slide on the slide rod 108, so that the lock buckle 105 can be disengaged from the wedge block 202, and then the male end 1 is pulled to make the plug 110 disengage from the socket 204, so that the male end 1 is disconnected from the female end 2.
