Block 205, by moving the pressing plate 2 downward, the fixing groove 204 can limit and fix the FFC cable 6, and the pressing block 205 can limit and fix the connecting terminal 5, while improving the connection effect between the FFC cable 6 and the connecting terminal 5, and can also effectively prevent the connecting terminal 5 and the FFC cable 6 from falling off, thereby improving the stability of the electrical connection; the two sides of the mounting plate 101 are fixedly connected with a fixing seat 3, and a fixing component is arranged inside the fixing seat 3. The fixing seat 3 and the fixing component enable the pressing plate 2 to be fixed inside the insulating shell 1, thereby improving the stability of the fixed limit of the connecting terminal 5 and the FFC cable 6.

[0032] Reference Figure 2-5 Slide grooves 102 are provided on both sides of the interior of the insulating shell 1, and sliders 203 are installed on both sides of the pressing plate 2. The sliders 203 are slidably connected to the interior of the slide grooves 102. Through the mounting plate 101 and the sliders 203, the pressing plate 2 can slide inside the insulating shell 1, so as to facilitate the limiting and fixing of the connecting terminals 5 and the FFC cable 6 inside the insulating shell 1; two groups of insulating gaskets 501 are installed on the surface of the connecting terminal 5, and the two groups of insulating gaskets 501 are arranged on both sides of the mounting plate 101. The two groups of insulating gaskets 501 on the surface of the connecting terminal 5 can improve the stability of the connection of the connecting terminal 5, prevent the connecting terminal 5 from falling off from the inside of the mounting plate 101, and improve the stability of the connection.

[0033] Reference Figure 2-4The fixing assembly includes a fixing block 303, a connecting rod 304 is slidably connected inside the fixing seat 3, one end of the connecting rod 304 extends to the inside of the fixing seat 3 and is connected to the fixing block 303, the other end of the connecting rod 304 extends to the outside of the fixing seat 3 and is connected to the handle 301, and fixing holes 202 matching the fixing block 303 are provided on both sides of the pressing plate 2, and the fixing holes 202 and the fixing block 303 are snap-connected, a groove is provided inside the fixing seat 3, and the fixing block 303 is slidably connected inside the groove, a spring 302 is installed on the inner side of the fixing block 303, and the other end of the spring 302 is fixed On the inner wall surface of the groove, the elastic action of the spring 302 can make the fixing block 303 inserted into the fixing hole 202, so as to fix the pressing plate 2. When the fixing effect needs to be canceled, the handle 301 is pulled to drive the fixing block 303 to move, so that the fixing block 303 moves out of the fixing hole 202, and the fixing effect of the pressing plate 2 can be canceled; a pull rod 201 is installed on the surface of the pressing plate 2, and the surface of the pull rod 201 is provided with anti-slip texture.
