[0002] Flexible flat cables are widely used to connect various motherboards and electronic components. Existing devices usually use multiple flexible flat cables inside. The scattered flexible flat cables inside the device not only take up space but also easily get entangled with each other.

[0003] In the prior art, for example, the utility model patent with authorization publication number CN210576922U discloses a flexible flat cable that is easily fixed. This flexible flat cable is designed with a clamping sleeve, a clamping frame, an L-shaped clamping plate, a positioning rod, a limit spring, a positioning hole, and a ball bearing. One end of the positioning rod on one flat cable body is manually pulled out of the clamping frame using a handle. Then, one end of the L-shaped clamping plate on the other flat cable body is inserted into the clamping frame of the above flat cable body, so that the two adjacent flat cable bodies are stacked together. Then, under the tension of the limit spring, the positioning rod passes through the positioning hole on one side of the L-shaped clamping plate in the clamping frame, thereby fixing the L-shaped clamping plate in the clamping frame, completing the stacking connection between the two flat cable bodies. Then, multiple flat cable bodies can be stacked together in sequence. The ball bearing on the inner wall of the clamping sleeve facilitates the movement of the clamping sleeve on the flat cable body, reducing the amount of space occupied by multiple flexible flat cables in the device, improving the neatness of the flexible flat cables in the device, and avoiding the existing problem of flexible flat cables being scattered inside the device, which not only takes up space but also easily gets entangled with each other.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0023] The present utility model provides a flexible flat cable that is easy to be clamped as Figures 1-5 shown, including a flexible flat cable 100 and a connection frame 200. Connectors 101 are installed at both ends of the flexible flat cable 100. The connection frame 200 is fixedly connected to the outer wall of the flexible flat cable 100. A card sleeve 300 is fixedly connected to the top end of the connection frame 200, and a clamping block 400 is fixedly connected to the bottom end of the connection frame 200. The upper and lower adjacent flexible flat cables 100 are detachably clamped and spliced through the card sleeve 300 and the clamping block 400. When multiple flexible flat cables 100 are stacked, the card sleeve 300 on the connection frame 200 on its outer wall can be clamped with the clamping block 400 on the connection frame 200 of the adjacent flexible flat cable 100, so that the adjacent two flexible flat cables 100 can be connected, avoiding entanglement and enabling neat storage while reducing the occupied space. Moreover, the structures of the clamping block 400 and the card sleeve 300 are simple, and the manufacturing cost is low, which better meets the use requirements.

[0024] Among them, the ferrule 300 includes a sleeve body 301. One side of the sleeve body 301 is provided with a recessed clamping groove 302. A limiting groove is formed in the inner wall of the clamping groove 302, and the cross-section of the limiting groove is L-shaped; the clamping block 400 includes a fixing plate 401. A cylindrical block 402 is fixedly connected to the side of the fixing plate 401 close to the sleeve body 301. The outer wall of the cylindrical block 402 is slidably connected to the inner side of the clamping groove 302. A limiting slider 403 is fixedly connected to the end of the outer wall of the cylindrical block 402 away from the fixing plate 401. The limiting slider 403 is matched with the limiting groove. When the ferrule 300 and the clamping block 400 are clamped, only need to insert the cylindrical block 402 into the clamping groove 302 of the sleeve body 301, and make the limiting slider 403 insert from the port of the limiting groove until its bent part, and then make the two flexible flat cables 100 rotate relatively, then the limiting slider 403 can be clamped into the bent part of the limiting groove, so as to achieve the limiting effect of reverse movement, and keep the clamping between the clamping block 400 and the ferrule 300 stable, achieving the anti-loosening effect.

[0025] Further, the limiting groove includes a straight groove 303 formed in the inner wall of the clamping groove 302. An arc groove 304 communicating with one end of the straight groove 303 is formed in the inner wall of the clamping groove 302. The straight groove 303 can enable the limiting slider 403 to move and insert into the sleeve body 301. At the same time, in cooperation with the arc groove 304, relative rotation occurs between the sleeve body 301 and the cylindrical block 402, so that the limiting slider 403 can be clamped into the arc groove 304 to achieve the limiting purpose.

[0026] In a preferred embodiment, the connecting frame 200 includes an upper clamping plate 201 and a lower clamping plate 202. The sleeve body 301 is fixedly connected to the top end of the upper clamping plate 201, and the fixing plate 401 is fixedly connected to the bottom end of the lower clamping plate 202. Locking mechanisms are provided at the ends between the upper clamping plate 201 and the lower clamping plate 202. The upper clamping plate 201 and the lower clamping plate 202 are connected and fixed through the locking mechanisms. The connecting frame 200 is composed of the upper clamping plate 201 and the lower clamping plate 202. With the locking mechanisms provided at the end positions between the upper clamping plate 201 and the lower clamping plate 202, the connecting frame 200 is a detachable splicing structure, so that the connecting frame 200 on the flexible flat cable 100 can be disassembled and assembled according to actual use requirements, which is more in line with actual use requirements;

[0027] In addition, the locking mechanism includes a telescopic groove 204 formed at the bottom end of the upper clamping plate 201. The telescopic groove 204 communicates with one side of the upper clamping plate 201. An L-shaped plate 205 is slidably connected in the telescopic groove 204. A return spring 206 is fixedly connected between the L-shaped plate 205 and the telescopic groove 204. A pressing head 207 is fixedly connected to the side of the L-shaped plate 205 away from the return spring 206. The pressing head 207 passes through the telescopic groove 204 and extends to the outside of the upper clamping plate 201. A clamping groove 203 is formed at the top end of the lower clamping plate 202. The cross-section of the clamping groove 203 is L-shaped. When the upper clamping plate 201 and the lower clamping plate 202 are butted, pressing the pressing head 207 drives the L-shaped plate 205 to move, so that the L-shaped plate 205 can be inserted into the clamping groove 203 on the lower clamping plate 202. Then, the pressure on the pressing head 207 is removed, and the elastic reaction force of the return spring 206 is used to drive the L-shaped plate 205 to move in the reverse direction. In this way, the bent part at the bottom of the L-shaped plate 205 can be inserted into the bent part at the bottom of the clamping groove 203, so as to achieve the vertical limiting effect, lock the upper clamping plate 201 and the lower clamping plate 202 together and prevent them from separating. When disassembling, only manually squeeze the pressing head 207 to drive the L-shaped plate 205 to move to directly unlock, and the operation is simple and convenient.
