Description

1241869 ---- 5. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a flexible circuit film (F 1 e X ib 1 e Printed Circuit, FPC), and in particular to a method having positioning reinforcement The flexible circuit film of the board. [Previous technology] In order to meet the requirements of modern electronic products for lightness, thinness, and shortness, various electronic components are actively developing toward the trend of miniaturization. As the functions of electronic products become more and more powerful, and the size of electronic products becomes smaller and smaller, various portable electronic products have flourished, and have replaced large electronic products, and gradually become the mainstream in the market, such as notebook computers ( Notebook), a mobile phone (Cell Phone), and a personal digital assistant (Personal Digital Assistant, PDA). In order to meet the requirements of miniaturization of various types of portable electronic products, in addition to the internal components must meet the requirements of small size and light weight, usually in order to make electronic products smaller and more convenient when carried To carry, the electronic product is designed into two units, and the two units are superimposed on each other. It is worth noting that the two units are usually connected by a flexible circuit film (F P C) that is flexible and can be bent at will to achieve the purpose of electrical conduction. Taking a notebook computer as an example, two units are designed. One of the units is, for example, a flat display module. The flat display module usually has a liquid crystal display panel, and the other unit is, for example, a main body. It usually has a circuit board. A flexible circuit film (FPC) has a plurality of contacts at one end, and is bonded with a crystal-glass (C h i ρ 0 n G 1 a s s), for example,

1 1084twf.pt d p. 6 ΏΑΙ & 69 V. Description of the Invention (2) The technology of C 0 G) is electrically connected to the liquid crystal display panel. In addition, the other end of the flexible circuit film also has multiple contacts, for example, it is connected to a connector, where the connector has multiple contact pins inside, and one end is plugged into the circuit board and connected to the circuit board. A patterned line is electrically connected, and the other end usually has a bent protrusion structure for contacting the contacts on the flexible circuit film to achieve electrical connection with the connector. The flexible circuit film is connected between the liquid crystal display panel and the circuit board, and the video signal can be transmitted from the circuit board to the liquid crystal display panel, so that the liquid crystal display panel can achieve the display function. As mentioned above, the conventionally arranged connectors on the circuit board can be divided into two types: open-type and drawer-type connectors. Among them, the open-type connector is engaged with the flexible circuit film in a rotating manner, so that the contacts on the flexible circuit film are electrically connected with the contact pins inside the connector, and the drawer-type connector is engaged in a sliding manner. The flexible circuit film electrically connects the contacts on the flexible circuit film with the contact pins inside the connector. It is worth noting that both open-type and drawer-type connectors have the disadvantage of weak snapping force, which can easily cause the flexible circuit film to fall off, resulting in short circuits. In addition, the mechanism of the open-type and drawer-type connectors is highly complicated. Among them, the open-type connectors need to be designed with a rotating shaft, and the drawer-type connectors need to be designed with slide rails. Such a mechanism design will lead to increased costs. In addition, the materials of the open-type and drawer-type connectors are usually plastic parts, and the mechanical stress is relatively poor. It is easy to cause the snap-in cover to fall or break during the rotation or sliding process, and its durability is not good. Φ Therefore, in order to improve the above-mentioned open connector and drawer connector

11084twf.ptd Page 7 ί244-Shengyi- V. Description of the Invention (3) Disadvantages The conventional technique proposes another type of plug-in connector. Figure 1A is a schematic diagram of a conventional plug-in connector and a flexible circuit film before assembly, and Figure 1B is a schematic diagram of a conventional plug-in connector and a flexible circuit film after assembly. Please refer to FIG. 1A and FIG. 1B together. It is known that the plug-in connector 1 0 0 is arranged on a circuit board 10. The connector 1 0 0 has a slot 1 2 and multiple contact pins 1. 0, and the contact pins 104 are located in the slot 102, and are electrically connected to a patterned circuit (not shown) on the circuit board 10.组装 When the assembler performs an assembling operation of the flexible circuit film 2000, one end of the flexible circuit film 200 is inserted into the slot 10, so that the plurality of contacts 2 on the flexible circuit film 200 end 0 2 can be in contact with the contact pins 104 in the slot 102, and the flexible circuit film 200 is electrically connected to the circuit board 10 through the connector 100. However, although the plug-in connector 100 has improved the mechanical complexity, since the thickness of the connector 100 is very thin (about 1.2 mm in), the flexible circuit film 2 0 0 is difficult to accurately insert into the slot 1 0 2 and the plugging process is too time consuming. Aiming at the problem that the flexible circuit film 2 0 0 is not easy to be inserted into the socket 1 0 2 of the connector 100, the conventional technology further adds a reinforcing plate 2 1 0 to the flexible circuit film 2 0 0, and the reinforcing plate 2 1 0 It has a connecting portion 2 1 2 and a handheld portion 2 1 4. The connecting portion 2 1 2 is disposed on the flexible circuit film 2 0 0 and is adjacent to the contact 2 2 of the flexible circuit film 2 0 2. Portion 2 1 4 —The end is connected to the connection portion 2 1 2 and the other end is warped upward for the convenience of assembly personnel. By using the reinforcing plate 2 1 0 as a force for inserting, the flexible circuit film 2 0 0 is inserted into the slot 1 0 2 of the connector 1 0 0 to make the flexible circuit

1 1084twf.pt d page 8 t24ig6-9 5. Description of the invention (4) The film 2 0 0 is electrically connected to the connector 1 0 0. It is worth noting that although the reinforcing plate 2 1 0 can be used as a force-applied tool for inserting the flexible circuit film 2 0 into the slot 1 0 2 of the connector 100, the insertion and removal speed is increased, but the reinforcing plate 2 1 0 is By inserting the flexible circuit film 200 into the socket 100 of the connector 100 in a moving manner, it is easy to cause a misconduct due to the flexible circuit film 200 being shifted around by the insertion process. In addition, the reinforcing plate 2 10 does not have a positioning design, and the flexible circuit film 200 is easily detached from the socket 100 of the connector 100. In addition, the design of the handheld portion 2 1 4 of the reinforcing plate 2 10 will occupy the space above the flexible circuit film 2 0, resulting in the thickness of the electronic product cannot be further reduced, which affects the development of the thinning of the electronic product. [Summary of the Invention] In view of the shortcomings of the conventional technology, the present invention provides a flexible circuit film with a positioning and reinforcing plate. The flexible circuit film has a non-zero insertion force (Non-Zero Insert Force, Non -ZIF) form and '^ plug-in connection and electrical connection' with positioning function can prevent the flexible circuit film from falling off, and the plugging process is very simple and fast.
