[0006] The third object of the present invention is to provide a hook portion with a guide angle based on the above-mentioned easy-lock and easy-unlock connector so as to receive the force generated by the flexible flat cable so that the hook portion is deformed on the elastic portion, and the elastic portion is also subjected to the reaction force generated by the fulcrum portion so that the elastic portion is deformed on the hook portion until the hook portion is no longer deformed on the elastic portion, so that the hook portion locks the flexible flat cable in the accommodating space.

[0007] The fourth object of the present invention is to provide a stopper sheet and a stopper block according to the above-mentioned easy-lock and easy-unlock connector, wherein the stopper sheet is arranged corresponding to the stopper block, and the stopper sheet is arranged on the stopper block so as to buckle the shell onto the insulator.

[0056] Please refer to Figure 1 , is a three-dimensional schematic diagram of the easy-lock and easy-unlock connector of the first embodiment of the present invention. Figure 1 In the figure, the easy-lock and easy-unlock connector 10 can connect the flexible flat cable 2 and the printed circuit board (not shown).

[0057] The easy lock and easy unlock connector 10 comprises a housing 12 , an insulator 14 and a terminal 16 . One end of the terminal 16 can be connected to the printed circuit board and the other end of the terminal 16 can be connected to the flexible flat cable 2 .

[0058] For reference Figures 2a to 2c , is to illustrate the present invention Figure 1 Detailed schematic diagram of the housing. Figure 2a This invention is described Figure 1 A top view of a shell; Figure 2b This invention is described Figure 1 a rear view of the housing; and, Figure 2c It is a side view of a housing for explaining the present invention.

[0059] The housing 12 includes a first body 122 , a locking component 124 , a first locking component 126 and a third locking component 128 .

[0060] The first body 122 forms a locking component 124, a first locking component 126, and a third locking component 128. In this embodiment, the number of the locking component 124 and the number of the third locking component are respectively two.

[0061] The locking member 124 extends from the surface of the first body 122 and can lock the flexible flat cable 2. Figure 3 , is a partial enlarged schematic diagram of the lock member of FIG. 2 of the present invention. The lock member 124 further includes a fulcrum portion 1242, an elastic portion 1244 and a hook portion 1246. The fulcrum portion 1242 is connected to the surface SF of the first body 122. The elastic portion 1244 connects the fulcrum portion 1242 and the hook portion 1246. Here, there is a height difference H between the fulcrum portion 1242 and the elastic portion 1244. In another embodiment, the hook portion 1246 forms a chamfer 1246' to receive the force generated by the flexible flat cable 2 so that the hook portion 1246 is deformed on the elastic portion 1244, and the elastic portion 1244 is also subjected to the reaction force generated by the fulcrum portion 144 mentioned later so that the elastic portion 1244 is deformed on the hook portion 1246 until the hook portion 1246 is no longer deformed on the elastic portion 1244, so that the hook portion 1246 locks the flexible flat cable 2 in the accommodating space SP mentioned later; conversely, by pressing the fulcrum portion 144, the elastic portion 1244 can be deformed to allow the flexible flat cable 2 to be unlocked from the hook portion 1246.

[0062] The first locking member 126 is bent from the surface of the first body 122 at an angle θ, for example, the angle θ ranges from 45 degrees to 135 degrees, and here, the angle θ is described as 90 degrees. In this embodiment, the first locking member 126 is described as an opening.

[0063] The third locking member 128 is formed on two sides of the first body 122. In this embodiment, the third locking member 128 is described by taking a stopper as an example.

[0065] In another embodiment, the first body 122 further includes a bridge portion 1211, which is disposed between the fulcrum portions 1242 (close to the edge of the housing) of the two locking members 124. By pressing the bridge portion 1211, the fulcrum portion 1242 of the locking member 124 can be driven to deform the hook portion 1246 and unlock the flexible flat cable 2. The free end of the bridge portion 1211 is bent toward the direction of the accommodating space SP to solve the problem that the flexible flat cable 2 is damaged due to uneven force or the hook portion 1246 is not completely unlocked due to the uneven force or the locking member 124 is pressed alone. Here, the bridge portion 1211 adopts a bent structure to prevent the deformation of the housing 12 caused by excessive pressing force.

[0066] In another embodiment, the first body 122 further includes soldering portions 1212, which are respectively formed on two sides of the first body 122. The soldering portions 1212 can be disposed (eg, soldered) on a printed circuit board.
