Description

  The present invention relates to a printed wiring board, and more particularly to a flexible printed wiring board.

  Generally, in an electronic device, a flexible printed wiring board is used to electrically connect circuit boards. When this flexible printed wiring board is connected to, for example, a connector fixed to a circuit board, the terminal portion provided at the end of the flexible printed wiring board is inserted into the insertion port of the connector.

However, since the conventional flexible printed wiring board is rich in flexibility, it is necessary to hold the terminal portion when inserting it into the connector, and the terminal portion is often bent at the time of insertion. There are drawbacks in that it bends and deforms, and fingers touch the terminal part to cause corrosion.

In order to deal with such drawbacks, for example, in Japanese Patent Application Laid-Open No. 2004-63113 (Patent Document 1), a grip portion that covers a contact portion is provided on a flat cable body having a contact portion for connecting to a connector at an end portion. It was something to prepare. Although this method is also a method, there is a limitation in giving the grip portion convenience other than covering the contact portion.

  An object of this invention is to provide the flexible printed wiring board with few restrictions by the convenience of a holding part.

In order to solve the above problems, a flexible printed wiring board according to the present invention includes a flexible printed wiring board main body having a contact portion for connecting to an external connector on one end surface, and the contact portion of the flexible printed wiring board main body. It is characterized by comprising a flat jig having one end fixed to the opposite surface and the other end being liftable as a gripping portion.

  According to the present invention, a flexible printed wiring board with less restrictions due to the convenience of the gripping part can be obtained.

  Examples of the present invention will be described below.

Example 1 of a flexible printed wiring board according to the present invention will be described with reference to FIGS.
FIG. 1 is a schematic view of Example 1 of a flexible printed wiring board according to the present invention. The flexible printed wiring board main body 1 may have a configuration including only a wiring board, but a configuration in which a coverlay film is attached to the wiring board with a baselay film or an adhesive is desirable for protection. The lower surface of the left end of FIG. 1 of the flexible printed wiring board 1 serves as a contact portion for connection to an external connector.

  A coverlay film 3 is attached on the flexible printed wiring board 1 with an adhesive 2. The right half of the coverlay film 3 is not fixed. On the cover lay film 3, reinforcing plates 4a and 4b are attached. As an example, the reinforcing plate 4b is formed by laminating dummy layers, and constitutes a grip portion together with the right half of the coverlay film 3. The reinforcing plate 4a may be created in the same manner as the reinforcing plate 4b, or the material and manufacturing method may be changed.

  FIG. 2 is an explanatory diagram of a usage example of this embodiment. For example, when inserting the flexible printed wiring board of the present embodiment into the external connector attached to the PCB, the gripping part is rotated by the flexibility of the coverlay film 3 and the operator holds it at an arbitrary angle. Can do.

  FIG. 3 is a schematic perspective view of the first embodiment. As an example of the contact portion, the flexible printed wiring board body 1 has a comb blade-like plug 5. FIG. 4 is a detailed explanatory diagram of a usage example of the first embodiment. In (a), the operator can insert the contact part into the connector easily and quickly in (b) by holding the gripping part with a finger and moving it in the direction of the arrow. FIG. 4 (c) shows the state of insertion completion after the operator releases the gripping portion, and the flexible printed wiring board is not damaged.

  A second embodiment of the flexible printed wiring board according to the present invention will be described with reference to FIGS. FIG. 5 is a schematic view of a flexible printed wiring board. Compared to Example 1, the reinforcing plate 4 b is attached to the opposite surface of the coverlay film 3. The adhesive 6 is attached to the place of the coverlay film 3 corresponding to the place where the reinforcing plate 4b was attached in Example 1, and the gripping part is fixed to the outer surface of the external connector.

  FIG. 6 is a detailed explanatory diagram of a usage example. The reinforcing plate 4b is an example attached to the same surface as in the first embodiment. An adhesive 6 is attached to the reinforcing plate 4b. Since the gripping portion is fixed to the outer surface of the external connector, it is prevented from coming off even when an external force in the direction of pulling out from the external connector is applied to the flexible printed wiring board.

  A third embodiment of the flexible printed wiring board according to the present invention will be described with reference to FIG. FIG. 7 is a schematic view of Example 3 of the flexible printed wiring board. The second flexible printed wiring board 7 is connected to the flexible printed wiring board 1 by, for example, pressure bonding as shown in FIG. As shown in (b), in the plug 8 as an example of the contact portion, the other end of the second flexible printed wiring board 7 is inserted into the second external connector. The plug 8 has a configuration in which the wiring of the flexible printed wiring board body 1 is branched.

FIG. 8 is a schematic view of another embodiment of the flexible printed wiring board according to the present invention. As shown in (a), the flexible printed wiring board is perforated so that the gripping part that is no longer necessary after insertion can be removed. It is.

Schematic of Example 1 of the flexible printed wiring board by this invention. FIG. 3 is an explanatory diagram of a usage example of the first embodiment. 1 is a schematic perspective view of Embodiment 1. FIG. FIG. 3 is a detailed explanatory diagram of a usage example of the first embodiment. Schematic of Example 2 of the flexible printed wiring board by this invention. FIG. 5 is a detailed explanatory diagram of a usage example of the second embodiment. The schematic of Example 3 of the flexible printed wiring board by this invention. Schematic of the other Example of the flexible printed wiring board by this invention.
