For example, an element, structure, article or device containing multiple elements is not limited to the elements listed herein, but may include other elements that are not explicitly listed but are generally inherent to the element, structure, article or device. In addition, unless expressly stated to the contrary, the term "or" refers to an inclusive "or" rather than an exclusive "or".

[0058] Please refer to Figure 1 , is a three-dimensional schematic diagram of an ultra-thin easy-lock and easy-unlock connector according to a first embodiment of the present invention. Figure 1 In the embodiment, the ultra-thin easy-lock and easy-unlock connector 10 can be connected as follows: Figure 6 A printed circuit board 4 and a flexible flat cable 2, Figure 6 It is a schematic diagram of an implementation of the ultra-thin easy-lock and easy-unlock connector of the present invention.

[0059] Back to Figure 1 The ultra-thin easy-lock and easy-unlock connector 10 includes a housing 12 , an insulator 14 and a terminal 16 .

[0060] One end of the terminal 16 can be connected to the printed circuit board 4 and the other end of the terminal 16 can be connected to the flexible flat cable 2 .

[0061] 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 An oblique view of a shell; Figure 2b This invention is described Figure 1 a top view of a housing; and, Figure 2c It is a sectional view taken along the line AA' for explaining the casing of the present invention 2b.

[0062] The housing 12 includes a first body 122 , a second body 124 and a turning portion 126 . The housing 12 forms a receiving space SP. The first body 122 is pivotally connected to the second body 124 via the turning portion 126 .

[0063] The first body 122 further includes a first buckle portion 1222 and a stopper 1224 . The first buckle portion 1222 is formed on two sides of the outside of the first body 122 , and the stopper 1224 is formed on two sides of the inside of the first body 122 .

[0064] The second body 124 further includes a locking member 1242 , a force-applying portion 1244 , and a second locking portion 1248 .

[0065] The second buckle portion 1224 is disposed corresponding to the first buckle portion 1222 to be able to interfere with each other, so that the first body 122 is combined with the second body 124. In this embodiment, the first buckle portion 1222 is a protrusion and the stopper 1224 is an extension.

[0066] The locking member 1242 can lock the flexible flat cable 2 in the accommodation space SP. In this embodiment, the locking member 1242 is broken from the second body 124 and suspended in the second body 124. The locking member 1242 further includes an action portion 12422, a hook arm 12424 and a hook portion 12426. The action portion 12422 is connected to the force application portion 1244. The hook arm 12426 connects the hook portion 12426 and the action portion 12422. Figures 5a to 5b , is a schematic diagram illustrating the implementation of the ultra-thin easy-lock and easy-unlock connector of the present invention. Figure 5a This invention is described Figure 1 The connection diagram of the ultra-thin easy-lock and easy-unlock connector to the flexible flat cable, and Figure 5b This invention is described Figure 5aBB' cross-sectional view of the ultra-thin easy-lock and easy-unlock connector connecting the flexible flat cable. After the flexible flat cable 2 is inserted into the accommodation space SP, the hook portion 12426 is pushed by the flexible flat cable 2 and lifted until the hook portion 12426 falls into the slot 22 of the flexible flat cable 2 (see Figure 5a ), so that the hook portion 12426 interferes with the card slot 22, and the flexible flat cable 2 cannot exit the accommodation space SP; on the contrary, when the external force F presses the force applying portion 1244, the force applying portion 1244 drives the action portion 12422, and the action portion 12422 lifts the hook portion 12426 through the hook arm 12424, so that the hook portion 12426 moves in the direction of leaving the accommodation space SP, so as to achieve the purpose of unlocking the hook portion 12426 from the card slot 22. It is worth noting that there is a height difference between the action portion 12422 and the hook arm 12424. In another embodiment, an inclined surface is formed between the action portion 12422 and the hook arm 12424 to correspond to the groove 146 mentioned later in the insulator 14. The inclined surface is set corresponding to the groove 146 to accommodate the deformation of the action portion 12422 and the hook arm 12424.

[0067] The force applying portion 1244 is disposed adjacent to the locking member 1242 . The force applying portion 1242 receives an external force F to drive the locking member 1242 so that the locking member 1242 unlocks the flexible flat cable 2 .

In addition, the limiting wall 1410 is provided corresponding to the force-applying portion 1244. When an external force F is applied to the force-applying portion 1244, the acting portion 12422 is driven to operate until the force-applying portion 1244 is stopped by the limiting wall 1410 and cannot drive the acting portion 12422 to operate, so as to prevent the operator from applying excessive force and damaging the structure of the ultra-thin easy-lock and easy-unlock connector.

[0072] In another embodiment, the insulator 14 further includes a positioning block 148 and the second body 124 further includes a positioning notch 12410. The positioning notch 12410 is disposed corresponding to the positioning block 148 to position the insulator 14 in the accommodation space SP.
