[0033] Preferably, a notch 115 is formed at the connection between the fixed section 111 and the contact section 112 and the deformation section 113, and the notch 115 facilitates the stamping of the contact section 112 and the deformation section 113.

[0034] Please refer to Figures 4 to 5 The socket insulation component 12 includes an integrally formed base 121 and a tongue plate 122 extending outward from the front end of the base 121.

[0035] Please refer to Figure 4 The tongue plate 122 has several longitudinally arranged receiving cavities 123, which penetrate the front and rear surfaces of the socket insulator 12. The crimp terminals 11 are installed one by one in the several receiving cavities 123.

[0036] The socket insulation member 12 includes a mounting groove 124 recessed inward from the bottom surface, which communicates with the upper and lower rows of receiving cavities 123 respectively. A positioning member 125 is provided in the mounting groove 124. The positioning member 125 has a through hole 1251 penetrating its front and rear surfaces. The positioning member 125 is fixed in the mounting groove 124. The through hole 1251 is connected to the receiving cavity 123 in the lower row.

[0038] The socket insulator 12 is recessed from the front end to form a clearance groove 126. The clearance groove 126 is located above the receiving cavity 123. An elastic arm 127 is provided between the clearance groove 126 and the receiving cavity 123. The elastic arm 127 is integrally formed with the socket insulator 12. One end of the elastic arm 127 is fixedly connected to the socket insulator 12, and the other end extends into the clearance groove 126, enters the window 114, and abuts against the contact section body 1121.

[0039] The socket insulation member 12 has a mating groove 1210 recessed inward from the front end face. The mating groove 1210 is located on the top and both sides of the tongue plate 122 and is used to mate the plug 2.

[0040] The tongue plate 122 is recessed inward from its upper surface to form a groove 1221. A movable buckle 120 is provided in the groove 1221. The diameter of the movable buckle 120 is smaller than the diameter of the groove 1221. It includes a buckle base 1201 and a pair of elastic tongue plates 1202 connected to the buckle base 1201. The buckle base 1201 is installed in the groove 1221 through the elastic tongue plates 1202. The buckle base 1201 and the base 121 are on the same horizontal line. Fixing blocks 1203 are formed on both sides. One end of the fixing block 1203 is connected to the side of the buckle base 1201, and the other end extends horizontally outward. The upper surface of the base 121 extends horizontally into the groove 1221 to above the fixing block 1203.

[0041] The bottom of the buckle base 1201 has a connecting block 1204, which is fixedly connected to the rear end of the pair of elastic tongue plates 1202.

[0042] Specifically, one end of the elastic tongue plate 1202 is installed at the front end of the tongue plate 122, and the other end is bent to the rear end of the tongue plate 122 and fixedly connected to the buckle base 1201. Preferably, the front surface of the elastic tongue plate 1202 installed on the tongue plate 122 is an arc surface.

[0043] A first protrusion 1205 is formed on the upper surface of the elastic tongue plate 1202. The side of the first protrusion 1205 near the front end of the tongue plate 122 forms a slope, and a reinforcing rib 1206 is provided on its outer side. The reinforcing rib 1206 extends from the outer side of the first protrusion 1205 along the upper surface of the elastic tongue plate 1202 and is fixedly connected to the fixing block 1203.

[0044] Preferably, an air-retaining area 1207 is formed between the pair of elastic tongue plates 1202.

[0045] Please refer to Figure 1 and Figure 6 The plug 2 includes a plurality of plug terminals 21 and a plug insulator 22 connected to the plurality of plug terminals 21.

[0046] The number of plug terminals 21 can be changed according to requirements. In this embodiment, the plug terminals 21 are 24 pins and are arranged in two rows along the longitudinal direction. The plug terminals 21 in the upper row are 8 pins and are fixed to the top two sides by the plug insulator 22 respectively. The plug terminals 21 in the lower row are 16 pins and are fixed to the bottom by the plug insulator 22.

[0047] The plug insulator 22 surrounds a mating space 221. The plug terminal 21 is fixedly connected to the plug insulator 22, with one end extending into the mating space 221 and the other end extending out of the plug insulator 22.

[0048] The interlocking space 221 is provided with a number of guide protrusions 222, which extend outward from the inner wall of the interlocking space 221 and are located at the top and sides of the interlocking space 221, respectively, for connecting the socket 1.

[0049] A second protrusion 223 is provided between the guide protrusions 222 at the top of the interlocking space 221. The second protrusion 223 is located at the front end of the interlocking space 221 and is fixedly connected to the guide protrusions 222.

[0050] In use, the anti-disengagement, quick-pluggable board-end connector of this utility model achieves initial positioning by engaging the guide protrusion 222 of the plug 2 with the mating groove 1210 of the socket 1. As the plug 2 continues to advance, the tongue plate 122 of the socket 1 gradually enters the mating space 221 of the plug 2, and the second protrusion 223 at the front end of the mating space 221 gradually contacts the elastic tongue plate 1202 of the movable buckle 120 of the socket 1. Since the front surface of the elastic tongue plate 1202 is curved and has its own elasticity, the second protrusion 223 will press the elastic tongue plate 1202 along the curved surface, causing the elastic tongue plate 1202 to deform into the groove 1221. When the plug 2 is pushed to the "fully mated" position, the second protrusion 223 passes over the first protrusion 1205 on the elastic tongue plate 1202 (the inclined surface of the first protrusion 1205 facilitates the sliding of the second protrusion 223). At this time, the elastic tongue plate 1202 loses its compression and resets under its own elasticity. The non-sloping side of the first protrusion 1205 and the second protrusion 223 form a "reverse limit" to lock the second protrusion 223, and the plug 2 and the socket 1 are connected. When it is necessary to disconnect, press the buckle base 1201, the first protrusion 1205 and the second protrusion 223 lose their resistance, and the plug 2 and the socket 1 are disconnected.

[0051] This utility model is a board-end connector with anti-disconnection and quick plug-in capability. It features a simple structure and easy operation. The integrated structure simplifies assembly and the snap-fit ​​design. While ensuring a stable connection performance, it not only lowers the technical threshold for production and assembly, but also makes daily operation more convenient. It is especially suitable for scenarios that require frequent plugging and unplugging or quick on-site installation, taking into account both practicality and economy.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the principles of the present utility model should be included within the protection scope of the present utility model.
