Abstract

PURPOSE:To remarkably enhance assemblability and yield by inserting a slider through a second opening after a flexible printed circuit board is inserted through a first opening, and electrically connecting the circuit board to a contact end part via a pressing means. CONSTITUTION:A pair of sliders 3 in which a housing 2 is inserted are pulled out until locking claws 3c abut on inner side surfaces of sides 2c, 2d of the housing 2. A flexible printed circuit board 6 is inserted through an opening 2b along an upper part flat surface of a pressing member 4 until a tip thereof abuts on an inner end surface 2h. Then, when the sliders 3 are inserted, edge parts 3d slide on a cam face 4a to push up the member 4 to press the circuit board 6 to a contact piece 5 with balanced pressure so as to conduct electric connection. In a sufficiently inserted position of the slider 3, a fitting part is fitted to an outer end extended part and can not be easily pulled out, so that generation of defective conductivity or the like can be prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector for electrically connecting a flexible printed circuit board having contact terminals arranged in high density to an electric circuit such as a printed wiring board.

[0002]

2. Description of the Related Art Conventionally, when a flexible printed circuit board is inserted into a housing of a connector, no force is required, and after the printed circuit board is inserted, a slider is pressed and bonded to a contact terminal in the housing of the connector. Is disposed in the vicinity of the printed circuit board, and the flexible printed circuit board is fixed by moving the slider in the same direction as the printed circuit board insertion direction.

[0003]

However, when the slider is moved in the same direction as the printed circuit board insertion direction as in the above-described conventional example, the direction in which the force for holding the printed circuit board in the housing and the force for moving the slider are applied. Since it is in the same direction, it is a structure that it is hard to apply force, and because the slider is arranged in the printed board insertion direction, when the slider is moved by a tool, the flexible printed board is cut or scratched In some cases, this is a cause of poor yield, and there is a problem in the assembling property.

The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to provide a connector having a significantly improved assembling property and a high yield.

[0005]

In order to achieve the above-mentioned object, the connector of the present invention comprises a first side surface having a first opening into which a flexible printed circuit board is inserted, and
A housing having at least one opening on a second side surface orthogonal to the side surface of the housing, and a second housing provided on the second side surface.
A slider having a fixing means with respect to the housing inserted through the opening of the housing, and a slider that is movably supported only in the direction pressing the contact end in the housing and in the opposite direction. And a pressing means for pressing and sandwiching the flexible printed circuit board between the contact end portion and the flexible printed circuit board so as to electrically connect the contact end portion to the flexible printed circuit board. Further, the movement of the pressing means in the direction of pressing the contact end portion with the insertion of the slider may be performed by a cam. Further, the slider may be integrally formed with the housing.

[0006]

In the connector having the above construction, the flexible printed circuit board is inserted from the first opening portion between the contact end portion and the pressing means, and then the slider is moved from the second opening portion along the cam surface below the pressing means. , The flexible printed circuit board is electrically connected to the contact end through the pressing means.
Since the flexible printed circuit board can be held in the housing and the slider can be moved with more force, the flexible printed circuit board can be cut and scratched when the slider is moved. The productivity can be significantly improved and the yield can be improved.
