DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-5 A stable contact FPC lock connector includes an upper rubber seat 200 and a lower rubber seat 100, the lower rubber seat 100 is provided with a rubber seat installation groove 110, the inner bottom surface of the rubber seat installation groove 110 is uniformly provided with a plurality of terminal installation grooves 120 along the length direction, and the terminal installation groove 120 is provided with a connection terminal 130;

[0027] A fixed mounting block 140 is formed on the side wall of the adhesive seat installation groove 110, and a fixed mounting hole is opened on the fixed mounting block 140. A rotating mounting hole 150 is opened at the rear end of the upper adhesive seat 200. A rotating shaft 160 is rotatably installed between the fixed mounting hole and the rotating mounting hole 150, and the upper adhesive seat 200 is rotatably matched on the fixed mounting block 140 through the rotating shaft 160;

[0028] An elastic member 171 mounting block 170 is formed between adjacent fixed mounting blocks 140, and an elastic member 171 is installed at the front end of the elastic member 171 mounting block 170. An abutting groove 210 is provided at the rear end of the upper rubber seat 200, and the elastic member 171 extends into the abutting groove 210. The side wall of the abutting groove 210 is provided with an oblique abutting surface 211 that abuts with the elastic member 171, and the oblique abutting surface 211 extends downward from the front to the rear, and the end of the lower rubber seat 100 is provided with a clamping structure 180 that clamps with the upper rubber seat 200.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, during the use of the FPC lock connector of the utility model, the front of the upper rubber seat 200 is first lifted upward to flip the cover, so that the clamping structure 180 at the end of the lower rubber seat 100 is separated from the upper rubber seat 200, and the upper rubber seat 200 is rotated and matched on the fixed mounting block 140 through the rotating shaft 160. During the upward rotation of the upper rubber seat 200, the side wall of the abutment groove 210 abuts and presses the elastic member 171, so that the elastic member 171 contracts, so that the operator can intuitively feel the resistance during the flipping process, and at the same time plays a buffering role to avoid damage to the upper rubber seat 200 caused by the operator flipping the cover at an excessively large angle. The upper rubber seat 200 is rotated upward to make the rubber seat mounting groove 110 leak out, so that the wiring terminal 130 leaks out, and then the flexible cable to be installed is installed in the rubber seat mounting groove 110 for connection;

[0030] After the flexible flat cable is installed in place, the upper rubber seat 200 is covered. During the covering process, the upper rubber seat 200 rotates and cooperates on the fixed installation block 140 through the rotating shaft 160, and the clamping structure 180 at the end of the lower rubber seat 100 is clamped and matched with the upper rubber seat 200, so that the upper rubber seat 200 is clamped and fixed on the lower rubber seat 100, thereby fixing the flexible flat cable. At the same time, the elastic member 171 restores its elastic deformation to generate an elastic abutting force on the side wall of the abutting groove 210, such as Figure 3 As shown, the side wall of the abutment groove 210 is provided with an oblique abutment surface 211 abutting against the elastic member 171, and the oblique abutment surface 211 is inclined downward from the front to the rear, and the force exerted by the elastic member 171 on the oblique abutment surface 211 includes a component of the force that makes the upper glue seat 200 downward, and through the elastic abutment effect of the elastic member 171, the upper glue seat 200 and the lower glue seat 100 have a better fixing effect on the flexible cable;

[0031] During use of the FPC lock connector of the utility model, the upper glue seat 200 and the lower glue seat 100 are rotated and matched through the rotating shaft 160, and the elastic member 171 elastically abuts the upper glue seat 200, so that the upper glue seat 200 can better adapt to the thickness error and assembly error of the flexible cable, thereby enhancing the stability of the contact between the terminal 130 and the flexible cable, making it less likely to fall off and loosen, and having a simple production structure, thereby reducing product costs.

[0032] In the embodiment of the utility model, the lower corner of the rear end of the upper glue seat 200 is provided with an arc-shaped abutment portion 230, and the arc-shaped abutment portion 230 shrinks evenly from front to back;

[0033] like Figure 3 As shown, during the process of opening the upper glue seat 200 by flipping the cover, the upper glue seat 200 rotates and cooperates on the fixed mounting block 140 through the rotating shaft 160. During the process of the upper glue seat 200 rotating along the rotating shaft 160, the arcuate abutting portion 230 rotates along the rotating shaft 160. Since the arcuate abutting portion 230 shrinks evenly from front to back, during the process of opening the upper glue seat 200 by flipping the cover, the distance between the arcuate abutting portion 230 and the inner bottom surface of the glue seat mounting groove 110 increases, so that the distance between the arcuate abutting portion 230 and the wiring terminal 130 increases, which is convenient for the installation of the flexible cable. After the flexible cable is installed in place, during the process of closing the upper glue seat 200, the distance between the arcuate abutting portion 230 and the inner bottom surface of the glue seat mounting groove 110 decreases, and the distance between the arcuate abutting portion 230 and the wiring terminal 130 decreases, which is convenient for the installation and fixation of the flexible cable.

[0034] In the embodiment of the utility model, a Z-shaped card installation groove 181 is formed at the end of the lower rubber seat 100, and the clamping structure 180 includes a clamping fixing member 182 clamped and installed in the card installation groove 181, and the clamping fixing member 182 is bent into a Z shape along the contour of the card installation groove 181, and a downward abutting rod 183 is formed at the end of the clamping fixing member 182, and an abutting protrusion 240 that abuts and cooperates with the abutting rod 183 is formed on the side of the upper rubber seat 200;

[0035] like Figure 5 As shown, the upper glue seat 200 is fixed by the abutment cooperation between the abutment protrusion 240 and the abutment rod 183. When the cover is lifted to flip, the abutment protrusion 240 is separated from the abutment rod 183. The upper glue seat 200 is rotated on the fixed installation block 140 through the rotating shaft 160. During the separation of the abutment protrusion 240 and the abutment rod 183, since the clamping fixing member 182 is bent into a Z shape along the contour of the clamping member installation groove 181, the clamping fixing member 182 has an elastic deformation effect, so that the abutment protrusion 240 and the abutment rod 183 are easy to separate;

[0036] After the flexible flat cable is installed in place, the upper glue seat 200 is covered. During the covering process, the upper glue seat 200 rotates and cooperates on the fixed mounting block 140 through the rotating shaft 160, and the abutting protrusion 240 is snap-fitted with the abutting rod 183, so that the upper glue seat 200 is snap-fitted and fixed on the lower glue seat 100, thereby fixing the flexible flat cable. During the snap-fitting process of the abutting protrusion 240 and the abutting rod 183, the snap-fitting fixing member 182 has the effect of elastic deformation, so that the abutting protrusion 240 and the abutting rod 183 are easy to snap-fit. At the same time, due to the elastic abutting cooperation of the snap-fitting fixing member 182, the upper glue seat 200 and the lower glue seat 100 have a better fixing effect on the flexible flat cable.

[0037] In the embodiment of the utility model, the end of the abutment rod 183 is provided with an abutment inclined surface 184 that abuts against the abutment protrusion 240;

[0038] The abutting area between the abutting rod 183 and the abutting protrusion 240 is increased, so that the abutting between the abutting rod 183 and the abutting protrusion 240 is more stable, and the abutting cooperation between the abutting rod 183 and the abutting protrusion 240 is facilitated.

[0039] In the embodiment of the utility model, a plurality of fixed mounting blocks 140 and elastic member 171 mounting blocks 170 are alternately provided along the length direction of the rubber seat mounting groove 110;

[0040] The connection between the upper glue seat 200 and the lower glue seat 100 is made more stable, the elastic contact distribution of the elastic member 171 on the upper glue seat 200 is made more uniform, and the force on the upper glue seat 200 is made more uniform.

[0041] In the embodiment of the utility model, the clamping structure 180 includes a first clamping structure 185 and a second clamping structure 186, and the first clamping structure 185 and the second clamping structure 186 are symmetrically arranged at the left and right ends of the lower rubber seat 100;

[0042] The clamping and fixing of the glue seat 200 is made more stable.

[0043] In the embodiment of the utility model, an elastic member mounting hole 173 is opened in the axial direction at the end of the elastic member mounting block 170, and the elastic member 171 includes a spring 174 and an abutment head 175. The spring 174 is installed in the elastic member mounting hole 173, one end of the spring 174 is fixedly connected to the inner bottom surface of the elastic member mounting hole 173, and the other end of the spring 174 is fixedly connected to the abutment head 175;

[0044] The elastic deformation of the spring 174 causes the abutment head 175 to elastically abut against the oblique abutment surface 211 .

[0045] During the use of the present invention, the front of the upper rubber seat 200 is first lifted upward to flip the cover, so that the clamping structure 180 at the end of the lower rubber seat 100 is separated from the upper rubber seat 200, and the upper rubber seat 200 is rotated and matched on the fixed mounting block 140 through the rotating shaft 160. During the upward rotation of the upper rubber seat 200, the side wall of the abutment groove 210 abuts and presses the elastic member 171, so that the elastic member 171 contracts, so that the operator can intuitively feel the resistance during the flipping process, and at the same time plays a buffering role to avoid damage to the upper rubber seat 200 caused by the operator flipping the cover at an excessively large angle. The upper rubber seat 200 is rotated upward to make the rubber seat mounting groove 110 leak out, so that the wiring terminal 130 leaks out, and then the flexible cable to be installed is installed in the rubber seat mounting groove 110 for connection;

[0046] After the flexible cable is installed in place, the upper rubber seat 200 is covered. During the covering process, the upper rubber seat 200 rotates on the fixed mounting block 140 through the rotating shaft 160, and the clamping structure 180 at the end of the lower rubber seat 100 is clamped and matched with the upper rubber seat 200, so that the upper rubber seat 200 is clamped and fixed on the lower rubber seat 100, thereby fixing the flexible cable. At the same time, the elastic member 171 restores its elastic deformation to generate an elastic abutment force on the side wall of the abutment groove 210.

[0047] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
