Description

The present invention relates to an FPC connector. In particular, the present invention relates to a connector for electrically connecting a flexible printed circuit board such as an FPC (Flexible Printed Circuit) or FFC (Flexible Flat Cable) to a hard printed circuit board (so-called rigid circuit board). This specification collectively refers to flexible printed circuit boards as FPCs, and the present invention relates to a structure of an FPC connector in which an FPC can be detachably attached from an oblique direction intersecting with one surface of a hard printed circuit board.

Generally, the FPC connector is mounted on a hard printed board. The FPC connector electrically connects the FPC and the printed circuit board. That is, the FPC connector is a printed circuit board connector.

It is known that there are two types of FPC connectors such as "horizontal mounting type" and "vertical mounting type". The horizontally mounted FPC connector allows the FPC to be inserted from a horizontal direction substantially parallel to one surface of the printed circuit board. The vertically mounted FPC connector allows the FPC to be inserted from a vertical direction substantially orthogonal to one surface of the printed circuit board.

The FPC connector of horizontal mounting type has an advantage that the mounting height of the printed board can be reduced because the FPC is inserted from the horizontal direction, but it is an obstacle to the attachment and detachment of the FPC. There is a difficulty that you can not place. As described above, the horizontally mounted FPC connector has a restriction that it is arranged at the end of the printed circuit board.

On the other hand, in the vertically mounted FPC connector, since the FPC is inserted from the vertical direction, there is no restriction on the arrangement on the printed circuit board, but it interferes with the attachment/detachment of the FPC, so another printed circuit board should be placed above the printed circuit board. It is difficult to arrange.

From the above, there is disclosed a first FPC connector that can maintain a low height by lowering the mounting height on a printed circuit board and relaxes restrictions on the mounting position on the printed circuit board (for example, Patent Document 1). reference).

In addition, it is possible to easily realize a low profile and prevent the housing and contacts from being excessively deformed even if the FPC received in the housing is raised upward. A connector is disclosed (for example, see Patent Document 2).

Referring to FIG. 17, the housing 91 has a recess 911 into which the terminal of the FPC 9f can be inserted. The recess 911 opens toward one end of the housing 91. Further, the housing 91 has a slope wall 912 that is inclined downward toward the bottom surface of the recess 911 and is intermittent in the width direction. These sloped walls 912 can guide the end of the FPC 9f in a downwardly inclined state from the entrance of the recess 911 to the inner side.

Referring to FIG. 17A, the contacts 92 are arranged in parallel inside the housing 91. Further, the contact 92 has a first elastic arm 921, a second elastic arm 922, and a connecting leg portion 923. The first elastic arm 921 and the second elastic arm 922 are arranged to face each other. The connection leg portion 923 connects the base end portions of the first elastic arm 921 and the second elastic arm 922.

With reference to FIG. 17A, the contact 92 is fixed to the housing 91 by press-fitting the connecting leg 923 into the housing 91 from the side opposite to the recess 911. The bottom surface of the connecting leg 923 is soldered to one surface of the printed board 9p.

The second FPC connector according to the related art does not require a cover housing for contacting the contact with the connection conductor of the FPC, and thus can provide an FPC connector that achieves a low profile.

The FPC connector according to the prior art shown in FIG. 16 or FIG. 17 is configured such that the FPC is inserted obliquely from above into a slot (insertion port) of a rectangular parallelepiped housing.

However, as a human operation habit, it is generally considered that the FPC is inserted from the direction orthogonal to the plane in which the slot is opened. That is, the conventional FPC connector has a problem that it is intuitively difficult to insert the FPC from an obliquely upper position. There is a risk of damaging the contacts by inserting the FPC from a direction orthogonal to the plane in which the slot is opened.
