This is done for convenience of illustration only and to provide a general sense of the scope of the invention. Thus, unless clearly indicated to the contrary, this description should be read to include one, at least one and the singular also includes the plural.

In the present disclosure, the terms "comprise," "include," "have," "contain," or any other similar terms are intended to cover non-exclusive inclusions. For example, an element, structure, article, or apparatus that comprises a plurality of elements is not limited to only those elements but may include other elements not expressly listed or inherent to such element, structure, article, or apparatus. In addition, unless expressly stated to the contrary, the term "or" is intended to mean an inclusive "or" rather than an exclusive "or".

Fig. 1 is a perspective view of an ultra-thin easy-to-lock easy-to-unlock connector according to a first embodiment of the present invention. In fig. 1, the ultra-thin easy-to-lock easy-to-unlock connector 10 is capable of connecting a printed circuit board 4 and a flexible flat cable 2 as shown in fig. 6, and fig. 6 is a schematic view of an implementation of the ultra-thin easy-to-lock easy-to-unlock connector of the present invention.

Returning to fig. 1, the slim type easy-to-lock easy-to-unlock connector 10 includes a housing 12, an insulator 14 and a terminal 16.

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.

Referring also to fig. 2a to 2c, there are shown detailed views of the housing of fig. 1 illustrating the present invention. FIG. 2a is an oblique view illustrating the housing of FIG. 1 of the present invention; FIG. 2b is a top view of the housing of FIG. 1 illustrating the present invention; and, FIG. 2c is a cross-sectional view A-A' illustrating the housing of invention 2 b.

The housing 12 includes a first body 122, a second body 124 and a turning portion 126. The housing 12 forms an accommodating space SP. The first body 122 is pivotally connected to the second body 124 through the hinge 126.

The first body 122 further includes a first latch portion 1222 and a stopper 1224. The first hooking portion 1222 is formed at both sides of the outside of the first body 122, and the stopper 1224 is formed at both sides of the inside of the first body 122.

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

The second latching portion 1224 is disposed corresponding to the first latching portion 1222 to interfere with each other, so that the first body 122 is coupled to the second body 124. In the present embodiment, the first locking portion 1222 is illustrated by a protrusion and a stopper 1224, which are extensions.

The locking member 1242 can lock the flexible flat cable 2 in the accommodating space SP. In the present embodiment, the locking member 1242 is broken from the second body 124 and suspended on the second body 124. The fastener 1242 further includes an action portion 12422, a hook arm 12424 and a hook portion 12426. The action portion 12422 is connected to the urging portion 1244. The hook arm 12426 connects the hook portion 12426 with the action portion 12422. Fig. 5a to 5b are schematic views illustrating an embodiment of the ultra-thin easy-to-lock/unlock connector of the present invention. Fig. 5a is a schematic connection diagram illustrating the slim type easy-to-lock easy-to-unlock connector of fig. 1 of the present invention connected to a flexible flat cable, and fig. 5B is a sectional view of B-B' illustrating the slim type easy-to-lock easy-to-unlock connector of fig. 5a of the present invention connected to a flexible flat cable. After the flexible flat cable 2 is inserted into the accommodating space SP, the hook portion 12426 is pushed by the flexible flat cable 2 to be lifted until the hook portion 12426 falls into the card slot 22 (see fig. 5 a) of the flexible flat cable 2, so that the hook portion 12426 interferes with the card slot 22 and the flexible flat cable 2 cannot exit from the accommodating space SP; on the contrary, after the force application portion 1244 is pressed by the external force F, the force application 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 toward the direction of separating from the accommodating space SP, thereby achieving the purpose of unlocking the hook portion 12426 separating from the card slot 22. It is noted that there is a height difference between the action portion 12422 and the hook arm 12424, and in another embodiment, an inclined surface is formed between the action portion 12422 and the hook arm 12424 to correspond to the groove 146 of the insulator 14. The inclined surface is disposed corresponding to the recess 146 for accommodating the deformation of the acting portion 12422 and the hook arm 12424.

The force application part 1244 is disposed adjacent to the locking part 1242, and the force application part 1242 drives the locking part 1242 by the external force F to make the locking part 1242 unlock the flexible flat cable 2.

In other embodiments, the second body 124 further includes a strengthening portion 1246 formed adjacent to the force application portion 1244. Here, the strengthening portion 1246 protrudes toward the accommodating space SP.

In another embodiment, the first body 122 further includes a first soldering portion 1226 formed on a side surface of the first body 122, and the first soldering portion 122 can be disposed (e.g., soldered) on the soldering point 42 of the printed circuit board 4; and, the second body 124 further includes a second welding part 12412 formed at a side of the second body 124. A second solder 12412 can be provided at another solder point 42 of the printed circuit board 4.

Referring also to fig. 3, a top view of the insulator of the present invention is illustrated. In fig. 3, the insulator 14 is disposed in the accommodating space SP through the stopper 1224 of the housing 12, and the combination of the housing and the insulator according to the present invention is illustrated with reference to fig. 4.

The insulator 14 includes a third body 142, an opening 144, and a retaining wall 1410. The opening 144 is disposed corresponding to the locking member 1242, so that the locking member 1242 can pass through the opening 144 to fasten the flexible flat cable 2. The stopper wall 1410 is provided corresponding to the biasing portion 1244. When an external force F is applied to the force application part 1244, the action part 12422 is driven to operate until the force application part 1244 is stopped by the limiting wall 1410 and cannot drive the action part 12422 to prevent an operator from damaging the structure of the ultra-thin easy-to-lock/unlock connector due to excessive force application.

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

Although the present invention has been described with reference to particular embodiments, it will be understood by those skilled in the art that various changes in form, construction, features, methods and quantities may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
