[0004] A first object of the present invention is to provide a connector with a locking and unlocking structure, which can connect a flexible flat cable and a printed circuit board.

[0005] A second objective of the present invention is to provide an integrated housing having an operating portion, a plurality of connecting portions and a plurality of action portions for combining with a rubber core according to the above-mentioned connector having a locking and unlocking structure.

[0006] The third object of the present invention is that according to the above-mentioned connector with locking and unlocking structure, the operating part is bent at an angle from two sides of the surface of the shell to extend multiple pressing parts to correspond to the multiple locking parts of the action part to achieve the purpose of linkage control.

[0007] A fourth object of the present invention is to provide a locking member for locking the notch of the flexible flat cable and for releasing the notch of the flexible flat cable by pressing the operating portion according to the above-mentioned connector with a locking and unlocking structure.

[0008] A fifth objective of the present invention is to provide a reinforcing structure for the housing of the connector with the locking and unlocking structure to prevent uneven force application and loss of deformation when external force is applied to the housing.

[0009] The sixth objective of the present invention is to provide a limiter through the shell and the rubber core respectively according to the connector with the locking and unlocking structure to combine the shell and the rubber core.

[0010] A seventh objective of the present invention is to enable the housing to be smoothly combined with the rubber core through the alignment piece of the housing and the alignment hole of the rubber core according to the above connector with the locking and unlocking structure.

[0011] The eighth objective of the present invention is to fix the housing to the rubber core through the mutual interference between the stopper of the housing and the stopper of the rubber core according to the above-mentioned connector with locking and unlocking structure.

[0012] To achieve the above and other purposes, the present invention provides a connector with a locking and unlocking structure, which can connect a flexible flat cable with a head end and a notch and a printed circuit board. The connector with the locking and unlocking structure includes a shell, a rubber core and a terminal. The shell includes an operating part, multiple connecting parts and multiple action parts. The operating part is formed on a surface of the shell. The operating part extends multiple pressing parts from two sides of the surface at an angle. The multiple connecting parts connect the operating part and the multiple action parts. The multiple action parts are arranged on two sides of the shell, and the multiple action parts form multiple locking parts corresponding to the multiple pressing parts. The multiple locking parts provide an elastic structure, an action structure and a snap structure. The action structure is arranged between the elastic structure and the snap structure. The action structure corresponds to each pressing part. The snap structure is arranged corresponding to the notch. The rubber core is combined with the shell. The rubber core forms a accommodating space for accommodating the flexible flat cable. The rubber core forms multiple openings and multiple terminal holes. The multiple openings allow multiple locking parts to be arranged in the accommodating space. One end of the terminal is disposed in the accommodation space and the other end of the terminal can be connected to the printed circuit board. The head end acts on the buckle structure, so that the buckle structure changes an initial state and moves in a first direction until the buckle structure locks the notch. The buckle structure moves in a second direction through the elastic structure and returns to the initial state; and an external force is applied to the operation part to deform multiple connection parts so that multiple pressing parts move in the first direction to drive the action structure of each locking part to deform the elastic structure, so that the buckle structure also moves in the first direction, so that the buckle structure can be separated from the notch.

[0013] To achieve the above and other purposes, the present invention provides a connector with a locking and unlocking structure for connecting a flexible flat cable with a head end and a notch and a printed circuit board. The connector with the locking and unlocking structure includes a shell, a rubber core and a terminal. The shell includes an operating portion, multiple connecting portions and multiple action portions. The operating portion is formed on a surface of the shell. The multiple connecting portions connect the operating portion and the multiple action portions. The multiple action portions are arranged on two sides of the shell. The multiple action portions form multiple locking members corresponding to the operating portion. The multiple locking members provide an elastic structure, an action structure and a snap structure. The action structure is arranged between the elastic structure and the snap structure, the action structure corresponds to the operating portion, and the snap structure corresponds to the notch. The rubber core is combined with the shell. The rubber core forms a housing space to accommodate the flexible flat cable. The rubber core forms multiple openings and multiple terminal holes. The multiple openings allow multiple locking members to be arranged in the housing space. One end of the terminal is arranged in the housing space and the other end of the terminal can be connected to the printed circuit board. The head end acts on the buckle structure, causing the buckle structure to change an initial state and move in a first direction until the buckle structure locks the notch. The buckle structure moves in a second direction through the elastic structure and returns to the initial state; and an external force is applied to deform the multiple connecting parts of the operating part to move the operating part in the first direction, thereby driving the action structure of each locking member to deform the elastic structure, so that the buckle structure also moves in the first direction, so that the buckle structure can be separated from the notch.
