Description

The present invention relates to a connector for FPC (flexible substrate) and FFC (flexible flat cable).

Conventionally, the shape of the terminal connected to the FPC or FFC is T-shaped when viewed from the side. A rotation support is provided at the center of the T-shape, and the driven contact portion is provided at the upper part of one side and the upper part of the other end. Some have a driving lever part, and by using a driving member for parallel operation or rotation operation, this driving lever part is moved up and down, and as a result, the contact part at the other end is moved up and down to make electrical contact. (Patent No. 3101951).

For that purpose, there were the following problems.
(A) Since the load for driving the node is inversely proportional to the length of the arm at the other end, in order to reduce the operating force of the driving lever, the arm on the driving side of the T-shape is lengthened or driven in the rotational operation. It was necessary to increase the length of the arm of the member, the length of the product was increased, and the occupied area was also increased.
(B) The strut in the center of the T-shape acts as the center of rotation, but the strut height is short, so the rigidity is high. To reduce the rigidity, the lateral width must be as small as possible and the dimensions must be strictly controlled. However, since this processing accuracy is directly related to the operating force and contact pressure, the variation in characteristics was large.
(C) Since the upper terminal is movable in a T shape, the part for fixing the terminal to the mold has to be provided on the lower side, which is one of the causes of warping of the product.
(D) Since the rotation direction of the drive lever is opposite to the insertion direction of the FPC or FFC, the exclusive area of the lever cannot be increased from the viewpoint of the projected area of the product, and the length of the lever is limited. As a result, the operating force of the lever was high and the operability was poor.
The present invention has been made to solve these problems.

The shape of the main part of the terminal was S-shaped when viewed from the side, the contact portion was the upper part inside the S-shape, the drive part was the upper end of the S-shape, and the driving strut was provided as a lateral part. In addition, the lever of the driving member for rotating operation is rotated from a retractable structure or the insertion side of the FPC or FFC.
A connector characterized by the above.

Due to the S-shape, the length of the drive lever can be brought close to the length of the driven contact part, the contact pressure and drive force can be adjusted easily, and there is no need to increase the area occupied by the drive part. With the same dimensions, it is possible to drive with a lighter force.

The column is a sideways member, and this part is a part that requires a common sense. Therefore, the member can be made longer than the T type, the rigidity and displacement can be easily managed, and a large displacement can be easily created. .

In the method of driving the driving lever from the front side, since there is no interference with the parts arranged on the outer periphery, the operability is high, the driving force is kept low, and the occupied area can be reduced.
In addition, since an excessive force is not applied to the board or the cable when the lever is operated, the reliability is high even in a fine pitch.

When the drive lever is of a telescopic type, it is highly effective for interference with the peripheral parts, the driving force is kept low, and the occupied area can be reduced.
In addition, since an excessive force is not applied to the board or the cable when the lever is operated, the reliability is high even in a fine pitch.

Since the column is sideways, a terminal press-fitting portion can be provided in the space below the S-shape, and the warping of the mold due to the press-fitting can be kept small.

Embodiments of the present invention will be described below mainly with reference to the drawings.
The connector (15) is mainly composed of a terminal (14), a housing (1), a drive lever (10), and a lifting prevention metal fitting (17).
(A) The side surface of the terminal (14) is generally S-shaped and has a linear portion on the lower side, and the lower contact (13) is provided on the left side of the lower contact (4). A rising portion (9) is provided at the root of (4), and a press-fitting portion (5) is provided at a substantially central portion of the rising portion (9). An upper contact portion (12) is provided on the upper side of the rising portion (9) on the side facing the lower contact (13), and a driven contact (3) is provided substantially parallel to the lower contact (4). The driving portion (2) is connected to the upper contact portion (12) and is substantially parallel to the driven contact (3), and the driving force acting portion (8) is provided at the end of the driving portion (2). A short-circuit portion (6) and a soldering portion (7) are provided substantially in parallel at a portion facing the lower contact (4) of the rising portion (9).
(B) The terminal (14) is connected to the housing (1) via the press-fit portion (5), and the lifting prevention metal fitting (17) is fixed to the left and right ends of the housing (1).
(C) A rotation lever (10) having a flat cam portion (11) between the driving force acting portion (8) and the short-circuit portion (6) of the terminal (14) is rotated in the direction of the substrate or cable. Are provided as the insertion side or the soldering part (11) side.
The present invention is configured as described above.
It is aligned with the mounting board (19) and connected to the mounting board via the lifting prevention metal fitting (17) and the soldering part (7). Thereafter, the drive lever (10) is lifted in the vertical direction, and a flat portion of the cam portion (11) is provided between the drive force acting portion (8) and the short-circuit portion (6), and a connected body (16 such as FPC or FFC). ) To the contact side and align. Thereafter, by closing the drive lever (10) forward or rearward, the cam part (11) is raised and the upper contact part (12) is driven downward by raising the drive part (2) to lower the lower part. The to-be-connected body (16) located between the contact parts (13) is pressurized and electrically connected.
In this case, in particular, when used by tilting to the rear side (soldering side), the drive lever (10) may be provided with an auxiliary lever (18) that can be extended and retracted. The lower contact (4) may be movable or used in a fixed form. Moreover, you may use only one side.
The press-fitting part (5) may be provided on the lower side as in the prior art. The drive lever may be a method based on a parallel operation instead of rotating (parallel cam method). Further, the cam (11) may be provided in a direction in which the upper and lower contact portions open. In this case, the cam (11) is driven when the connected body (16) is taken out.
