[0005] The second object of the present invention is to provide a connector with a locking and unlocking structure to form an operation portion, a plurality of connecting portions and a plurality of locking portions in a single housing to combine a core.

[0006] The third object of the present invention is to provide a connector with a locking and unlocking structure to connect the connecting portion from the surface to the side of the housing to connect the locking portion, so that the locking portion is connected to the operation portion.

[0007] The fourth object of the present invention is to provide a connector with a locking and unlocking structure to provide a gap of the locking portion to lock the flexible flat cable and a gap to separate the flexible flat cable by pressing the operation portion.

[0008] The fifth object of the present invention is to provide a connector with a locking and unlocking structure to provide a base and an operation portion to be separated or connected, when the base and the operation portion are separated, the base is a fulcrum of the operation portion, and when the base and the operation portion are connected, the base is a fulcrum of the operation portion.

[0009] The sixth object of the present invention is to provide a connector with a locking and unlocking structure to provide a limiting member in the housing and the core to combine the housing and the core.

[0010] The seventh object of the present invention is to provide a connector with a locking and unlocking structure to provide a positioning member in the housing and a positioning hole in the core to combine the housing and the core.

[0011] The eighth object of the present invention is to provide a connector with a locking and unlocking structure to provide a stop member in the housing and a stop block in the core to combine the housing and the core.

[0012] To achieve the above and other objectives, the present invention provides a connector with a locking and unlocking structure for connecting a flexible flat cable having a head end and a notch to a printed circuit board. The connector with the locking and unlocking structure includes a housing, a core, and a terminal. The housing includes an operating portion, a plurality of connecting portions, and a plurality of locking portions. Each locking portion includes an actuating structure, a base, and a snap-fit ​​structure. The operating portion is formed on the surface of the housing. The plurality of connecting portions connect the operating portion and the actuating structure of the plurality of locking portions, and the plurality of connecting portions extend downward from the surface along one side of the housing. The plurality of locking portions are disposed on both sides of the housing. The actuating structure connects the base and the snap-fit ​​structure.

[0065] The housing 12 includes an operating part 122, a connecting part 124, and a locking part 126. The operating part 122, connecting part 124, and locking part 126 are formed by bending the housing 12. In other words, the operating part 122, connecting part 124, and locking part 126 are formed from the same housing 12. In this embodiment, the number of operating parts 122 is illustrated as one, and the number of connecting parts 124 and locking parts 126 are illustrated as two each. The connecting part 124 and locking part 126 are respectively provided at both ends of the operating part 122.

[0066] An operating portion 122 is formed on the surface SF of the housing 12. The operating portion 122 extends from the front side of the surface SF at an angle θ to form a connecting portion 124, for example, the angle θ may be 90 degrees. In another embodiment, the surface SF of the housing 12 may also be provided with a reinforcing structure 128.

[0067] The locking portion 126 is disposed on both sides of the housing 12. The locking portion 126 comprises an acting structure 1262, a base 1264 and a clamping structure 1266. The connecting portion 124 connects the operating portion 122 and the acting structure 1262 of the locking portion 126. The connecting portion 124 makes the operating portion 122 suspended on the locking portion 126.

[0068] Here, the clamping structure 1266 is disposed corresponding to the gap 24. The acting structure 1262 connects the base 1264 and the clamping structure 1266. In the embodiment, the base 1264 and the pressing member 1222 are in a separated / non-contact state. Here, the acting structure 1262 is L-shaped, used to form a C-shaped body with the base 1264, and the acting structure 1262 further comprises a first elastic member 1262' and a second elastic member 1262".

[0069] Referring to Figure 4 , it is a combination schematic diagram of the housing and the flexible flat cable of the present application. In Figure 4 , when the head end 22 acts on the clamping structure 1266, the clamping structure 1266 changes from an initial state and moves in a first direction FD until the clamping structure 1266 locks the gap 24. The clamping structure 1266 is moved by the acting structure 1262 in a second direction SD to return to the initial state. Also, by applying an external force to the operating portion 122, the connecting portion 124 is deformed to allow the acting structure 1262 to move in the first direction and the clamping structure 1266 to move in the first direction FD, so that the clamping structure 1266 can be separated from the gap 24.

[0070] Referring back to Figure 3a and 3b , the locking portion 126 (or the base 1264) further comprises a fixing portion 1268 formed on both sides of the housing 12, so as to fix the housing 12 on the printed circuit board.

[0071] Also, the base 1264 further forms a first limiting member 12614, 12610.

Here, the first limiting member 12614 is illustrated by taking a hole as an example and the first limiting member 12610 is illustrated by taking a spring as an example.

[0072] Also, the base 1264 further comprises a positioning member 12612, which is illustrated by taking a plug as an example. The positioning member 12612 is formed on the front edge of the housing 12.

[0073] Further, the surface SF also forms a positioning notch 123 for positioning a block 148 of the core 14 to be mentioned later. The housing 12 is combined with the core 14 by positioning the block 148 through the positioning notch 123.

[0074] Referring to Figure 5a to Figure 5c , a detailed structure of the core of the present application is illustrated. Figure 1 is a detailed structure of the core of the present application. Figure 5a is a rear view of the core, Figure 5b is a top view of the core, and Figure 5c is a front view of the core.

[0075] The core 14 is combined with the housing 12. The core 14 forms a space SP for accommodating the flexible flat cable 2. The core 14 forms an opening 146 and a terminal hole 144. The opening 146 allows the locking portion 126 to be disposed.

[0076] Further, the core 14 also includes second positioning members 1410, 1412. In the present embodiment, the second positioning member 1412 is formed in the rear of the core 14, and the second positioning member 1410 is formed in the side of the core 14. Here, the second positioning member 1412 is illustrated by way of example as a snap block, and the second positioning member 1410 is illustrated by way of example as a snap groove. The second positioning members 1410, 1412 are respectively disposed corresponding to the first positioning members 12614, 12610. The housing 12 is positioned in the core 14 by the second positioning members 1410, 1412 combined with the first positioning members 12614, 12610.

[0077] Further, the core 14 also includes a positioning hole 143. The positioning hole 143 is disposed corresponding to the positioning member 12612. The housing 12 is positioned in the core 14 by the positioning member 12612 engaged with the positioning hole 143, and the housing 12 can be accurately combined with the core 14.

[0078] Returning to Figure 1 , one end of the terminal 16 is disposed in the space SP, and the other end of the terminal 16 can be connected to a printed circuit board. The terminal 16 is inserted in the terminal hole 144.

[0079] The combination of the aforementioned first positioning members 12614, 12610, the second positioning members 1410, 1412, the positioning member 12612, and the positioning hole 143 can be collectively referred to Figure 6 for explanation.
