Description

Connector with locking and unlocking structure

[ technical field ] A method for producing a semiconductor device

The present invention relates to a connector, and more particularly to a connector having a locking and unlocking structure.

[ background of the invention ]

The conventional connector, such as the LVDS connector, is unlocked by an unlocking device located at the cable end, which requires a large space for operation, and the cable end cannot be clearly determined to be unlocked or still in a locked state, so that the cable is forcibly pulled out without unlocking, which may cause a lock failure of the locking structure. Although the pull rod structure achieves the purpose of automatic locking and automatic pop-up unlocking and can easily identify the locking and unlocking states, when the connector is applied in a small or even micro application field, the user will not easily operate the pull rod.

In view of the above, the present invention provides a connector with a locking and unlocking structure to solve the problems caused by the conventional connector or the problems that cannot be solved.

[ summary of the invention ]

The first objective of the present invention is to provide a connector with a locking and unlocking structure, which can connect a printed circuit board and a flexible flat cable to achieve the purpose of locking the flexible flat cable.

The second objective of the present invention is to provide a connector with a locking and unlocking structure, wherein the first insulator forms an alignment member and the second insulator forms an alignment member, so that the male connector can be easily assembled with or separated from the female connector.

A third objective of the present invention is to provide the connector with locking and unlocking structure, wherein when the first insulator moves toward the second insulator, the pressing member rotates in a first rotation direction, so that the first insulator is locked to the second insulator, and rotates in a second rotation direction, and the first insulator is pushed by the pressing member to separate from the second insulator.

A fourth object of the present invention is to provide a grounding terminal of the flexible flat cable and the printed circuit board with a plurality of contact elements according to the connector with the locking and unlocking structure, so as to increase the grounding area of the connector and avoid the interference of electromagnetic waves.

The fifth objective of the present invention is to provide a positioning element and a positioning notch according to the connector with the locking and unlocking structure, wherein the positioning element is disposed corresponding to the positioning notch, and the positioning element is disposed in the positioning notch to fasten the housing to the insulator.

To achieve the above and other objects, the present invention provides a connector with a locking and unlocking structure capable of connecting a printed circuit board and a flexible flat cable having a first grounding copper foil surface and a second grounding copper foil surface. The connector with the locking and unlocking structure comprises a male head and a female seat. The male connector includes a first housing, a second housing and a first insulator. The first shell is combined with the second shell to wrap the first insulator. The first insulator forms an accommodating space at one side of the first shell to accommodate the flexible flat cable. The first insulator forms a first positioning element, a third positioning element, a fifth positioning element and a first acting element. The first positioning piece penetrates through the accommodating space. The third positioning element and the fifth positioning element extend towards a first direction. The first direction is approximately equal to or equal to 90 degrees from the insertion direction of the flexible flat cable. The first acting piece is formed on the corresponding side of the first shell inserted into the flexible flat cable. The female seat comprises a second insulator, a pressing piece, a fixing piece and a terminal. The second insulator is combined with the pressing piece, the fixing piece and the terminal. The second insulating part comprises a second positioning part, a fourth positioning part and a sixth positioning part. The second positioning piece is arranged corresponding to the first positioning piece. The fourth positioning piece is arranged corresponding to the fifth positioning piece. The sixth positioning piece is arranged corresponding to the third positioning piece. The fixing member can fix the second insulator to the printed circuit board. When the first insulator moves towards the second insulator, the pressing piece rotates in a first rotating direction, so that the first insulator is buckled on the second insulator, and the pressing piece rotates in a second rotating direction, and the first insulator is pushed by the pressing piece to be separated from the second insulator.

Compared with the conventional connector, the connector with the locking and unlocking structure provided by the invention can be easily combined with the printed circuit board provided with the second component by providing the flexible flat cable to be combined with the first component in advance, so that the flexible flat cable can be easily locked on the printed circuit board, and the flexible flat cable can be easily electrically connected with the printed circuit board or easily separated from the printed circuit board through the pressing piece with a large area.
