Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a flexible circuit board connector.

[0002]

[Prior art]

 Flexible Printed Circuits (referred to as FPCs or “soft” circuit boards) are applied to products used in flexure, such as notebook PCs and electronic dictionaries. Notebook PCs, electronic dictionaries, etc. meet the requirements of being light, thin and small, and are conveniently carried. The connectors connected to the flexible circuit board must also meet the requirements of being light, thin and small.

As shown in FIGS. 6 and 7, a conventional flexible printed circuit board connector (referred to as a “flexible printed circuit” or “soft” circuit board connector) has an insulated base base having a cross section in the shape of a “C”. The conductive element 51 and the conductive element 51 'of the U-shaped resilient movement part 511 and the resilient movement part 511' are fitted in the insertion groove 501. The conductive element 51 penetrates the insulating base 50 to the left, and the electric element 51 'extends to the outside of the insulating base 50 to the right. Since the soft flexible circuit board 52 is pinched by the connector, the conductive element 51 and the conductive element 51 'are provided with a spring part 511 and a spring part 511'. The conductive element 51 and the conductive element 51 'are vertically positioned by the upper jaw pinch 511a and the upper jaw pinch 511a' above the spring motion section 511 and the spring motion section 511 'and the lower lower jaw pinch 511b and the lower jaw pinch 511b'. Makes conductive contact with the flexible circuit board 52 to pinch the flexible circuit board 52.

The gap 512 and the gap 512 ′ between the upper jaw pinches 511 a and 511 a ′ and the lower jaw pinches 511 b and 511 b ′ must be formed smaller than the thickness of the flexible circuit board 52. Therefore, there are the following problems.

[0005] 1. It is difficult for the soft flexible circuit board 52 to be inserted into the very small gaps 512 and 512 'between the upper jaw 511a and the upper jaw 511a' and the lower jaw 511b and the lower jaw 511b '. 2. In order to reduce the space occupied by the connector, the spring movement part 511 and the spring movement part 511 ′ are attached to the bottom of the insulating base stand 50. For this reason, it is difficult to insert the soft flexible circuit board 52 horizontally.

[0006] 3. The flexible circuit board 52 is inserted into a gap 512 and a gap 512 'between the upper jaw clip 511a and the upper jaw clip 511a' and the lower jaw clip 511b and the lower jaw clip 511b ', and is fixed by crimping with a plastic push plate. Plastic plates are not suitable for use because of their weak fixing force and easy tearing.

[0007]

[Problems to be solved by the invention]

 However, conventional connectors cannot easily insert a soft flexible circuit board into the gap between the upper and lower jaw clamps. In addition, to reduce the space occupied by the connector, a U-shaped spring is installed at the bottom of the insulating base, making it difficult to insert the circuit board horizontally. In addition, the circuit board is inserted into the gap between the upper jaw clamp and the lower jaw clamp and is crimped with a plastic push plate, but the plastic push plate has a weak fixing force and easily tears. Therefore, an object of the present invention is to provide a flexible circuit board connector which can easily insert a flexible circuit board and has a high fixing force.

[0008]

[Means for Solving the Problems]

 According to the flexible circuit board connector according to the present invention, the insulating base is a base, has a first side, a second side faces the first side, and a first side is The first side is connected to one end of the second side and the second side is connected to the other end of the first side and the second side. The insulating base has a contact surface, and the contact surface is provided with a plurality of insertion grooves. The slot extends through the contact surface and is exposed from the contact surface. The first side of the insulating base has a mating contact that projects from the contact surface and has a mating rim. A biting groove is formed between the biting portion and the contact surface. The conductive element is provided inside the insertion groove and has a contact portion. The contact is exposed from the contact surface and is disposed outside the meshing contact and is in conductive contact with the conductive contact of the flexible circuit board. The flexible circuit board is inclined, inserted into the engagement groove, rotated about the engagement groove toward the contact surface, and makes conductive contact with the conductive element. The metal press plate element has a first edge, a second edge faces the first edge, a third edge is connected to one end of the first edge and the second edge, and a fourth edge. Is connected to the other ends of the first and second edges. Both ends of the first edge have a pivoting portion and a hooking portion, and the pivoting portion is pivotally connected to both ends on the first side. The metal stamping plate element is rotated in the direction of the insulating base, is fastened to the insulating base, covers the surface of the flexible circuit board, and the hooking portion and the insulating base are engaged. Therefore, the flexible circuit board connector allows the flexible circuit board to be easily inserted into the conductive element, is easy to operate, and has a strong fixing force.
