DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a flexible printed circuit board having a spring property for exhibiting a sufficient contact force.
The present invention relates to a small and low-profile FPC connector for stably connecting the FPC.

[0002]

2. Description of the Related Art Conventionally, as an example of a known technique related to this type of FPC connector, in the case of a flat cable connector disclosed in Japanese Patent Application Laid-Open No. 9-82427, the main body is mounted on a printed (wiring) board. Specifically, the housing is configured to be connectable, and specifically has a housing that is open at the top with the insertion direction of the flat cable in the front-rear direction, and a contact that extends rearward from the front of the housing and is electrically connected to the flat cable at the tip. A first contact having a contact piece and a lead terminal piece provided with a fixed portion and being attached from the front side of the housing, and a flat cable extending forward from the rear of the housing and having a flat cable at the tip thereof. A contact piece provided with a contact portion to be brought into contact with the housing, and a lead terminal piece. By providing a second contact to be attached, and a lever portion rotatably supported by the elastic support piece of the second contact and pressing and fixing the flat cable, each contact can be moved in the front-rear direction of the housing. By deploying, the overall size of the connector is reduced.

As another example of a well-known technique related to an FPC connector, in the case of a connector with a latch disclosed in Japanese Patent Application Laid-Open No. 8-31526, the main body is configured to be mountable and connectable on a printed (wiring) board. However, here, a large number of contact pins are mounted in parallel in the front-rear direction of a plastic housing, and a reinforcement attached to a printed circuit board or flexible conductor on one or both sides in the width direction of the housing. It is pushed outward by a board,
And, when they are pushed to a predetermined position, they return to their original positions and are provided with a plastic latch which presses and holds the printed circuit board or the reinforcing plate, and furthermore, a reinforcement provided on the latch itself to receive a contact pressure applied to the latch. By forming a latch, a latch of the reinforcement itself, a mounting portion for mounting on the housing, and a supporting portion fixed to a printed circuit board on which the housing is set, the printed circuit board due to the creep deformation of the latch is formed. The overall size of the connector is reduced while preventing poor contact of the contact pins and damage to the latch when inserting and removing the printed circuit board.

Further, as another example of a well-known technique relating to an FPC connector, in the case of a flexible circuit board connector disclosed in Japanese Patent Application Laid-Open No. H11-54220, the main body can be mounted and connected on a printed (wiring) board. However, in this case, the contact portion is formed as a metal plate surface and the tongue piece is provided in an insulating housing containing a plurality of contacts staggered so as to be capable of contacting one surface side of the flexible circuit board. The member is provided rotatably, the posts and the elastic engagement pieces on both sides thereof are engaged with each other at the open position of the pressing member and are prevented from coming off with respect to the insulating housing, and the post and the elastic engagement piece are at the closed position. Is disengaged, the locking projection and the insulating housing are locked, and the tongue is engaged with a part of the contact to be maintained on the insulating housing, thereby securing the flexible circuit board. It is configured to provide sufficient contact force in which electrical connection is pressed toward the Ntakuto.

[0005]

In the case of a connector used for connection to a printed (wiring) board and connection to a flexible flat cable as described above, it is generally necessary for the connector to be structurally required to secure basic functions. In particular, the spring length of the contact spring piece is required to have a certain length in order to realize a contact force for obtaining stable contact, and a press-fit piece for fixing each contact to the housing. And securing a space for mounting metal parts as reinforcing metal fittings that are grounded to the printed circuit board.These requirements are to reduce the overall size and height of the connector, which is required recently. There is a problem that it is an obstacle to realizing (thinning).

More specifically, in the case of the flat cable connector disclosed in Japanese Patent Application Laid-Open No. 9-82427,
By arranging the contacts in the front-rear direction of the housing, the overall size of the connector is reduced. Here, leg terminal pieces for electrical connection to the printed circuit board of each contact extend in both sides of the housing. As a result, the spring length of the contact spring piece at each contact for obtaining a stable contact force as the outer shape of the entire connector is shortened, and thereby a stable contact state with the flat cable is not obtained. There is a problem that there is. Also, in the case of the connector here, the press-fitting piece for fixing to the housing in each contact is a bifurcated piece and one of the pieces located on the lower side or the upper side is used. However, there is a problem that the mold thickness of the housing becomes thinner to realize the realization, so that sufficient mechanical strength cannot be secured.

On the other hand, in the case of the connector with a latch disclosed in Japanese Patent Application Laid-Open No. 8-31526, the size of the entire connector is reduced by arranging the contacts in the front-rear direction of the housing. In addition, there is a problem that a space is required for a leg terminal piece for making an electrical connection to a printed circuit board in the above, and it is difficult to reduce the size when securing the spring length of the contact spring piece. Metal parts for fixing the printed circuit board (for fixing the connector in a stable position on the printed circuit board and at the same time improving the connection strength of the flexible conductor) must be attached separately from the contacts in the direction opposite to the terminal piece. Therefore, the space for attaching the metal parts to the housing reduces the size of the entire connector or reduces the height (thinness) of the connector. There is a problem that has become an obstacle to above.

On the other hand, in the case of the flexible circuit board connector disclosed in Japanese Patent Application Laid-Open No. 11-54220, a pressurizing member having a tongue piece is rotatably provided in an insulating housing, and the tongue piece is moved to the flexible circuit board in its closed position. Is pressed against the contact to provide a sufficient contact force when making an electrical connection, but here, the tongue of the pressing member increases the space for rotating the flexible circuit board so that it can be pressed. Direction, and it is necessary to secure a certain dimension in the height direction. Therefore, the space for allowing the tongue piece of the pressure member to be rotatable can reduce the size of the entire connector or reduce the height of the connector. There is a problem that it is hindered in making it thinner.
