Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a connector, and more particularly to a connector for flexibly connecting, for example, two printed circuit boards to each other in wiring in an electronic device.

[0002]

[Prior Art]

 In the conventional connector, as shown in FIG. 8, a plurality of long conductors 11 are arranged in parallel between two first insulators 2a and 2b. The first insulators 2a and 2b and the conductor 11 are simultaneously molded. Further, a plurality of walls 2d extending upward are integrally formed with the first insulators 2a and 2b, respectively. The ends of the conductors 11 are positioned and held in a one-to-one relationship between these walls 2d to prevent contact between the ends of the conductors 11. By arranging the first insulators 2a and 2b on both sides of the conductor 11 in the longitudinal direction, the intermediate conductor portion 12 of the conductor 11 has flexibility. In order to prevent a short circuit due to contact between the conductor 11 and the intermediate conductor 12 adjacent to each other, the two second insulators 2c are fixed to the intermediate conductor 12 by bridging the intermediate conductors 12 in the arrangement direction. The movement of the part 12 is blocked. The second insulator 2c is formed at the same time as the insulators 2a and 2b at both ends.

[0003]

[Problems to be solved by the device]

 However, in the above-described conventional connector, the wall 2d is provided between the conductors 11 in order to prevent a short circuit between the adjacent intermediate conductor portions 12, or the intermediate conductor portion 12 in the longitudinal direction of the conductor 11 is provided with a wall. It is necessary to adopt a complicated structure such as bridging and fixing the second insulator 2c.

Further, in this connector, the intermediate conductor portion 12 between the first insulators 2a and 2b is in a bare state. For this reason, when this is mounted between printed circuit boards, it is impossible to prevent contact with another intermediate conductor portion 12 adjacent thereto. Furthermore, if the intermediate conductor portion 12 of the conductor 11 is exposed in this way, the neighboring intermediate conductor portion 12 will come into contact when the pitch of the conductor 11 is narrowed due to the recent lighter, thinner and smaller consumer and industrial equipment. There is a risk of short circuiting. Therefore, there is a limit in dealing with this kind of narrow pitch.

Therefore, an object of the present invention is to provide a connector which can easily prevent a short circuit due to contact with another conductor and a neighboring conductor without losing flexibility and can cope with a narrow pitch. To do.

[0006]

[Means for solving problems]

 According to the present invention, a plurality of long conductors and an insulator having the conductors arranged in parallel and holding both ends of the conductor are held, and the intermediate conductor portion of the conductor between the insulators is flexible. In the connector having, an insulating member for preventing a short circuit between adjacent intermediate conductor portions is provided, the insulating member is provided in the intermediate conductor portion, and the insulating member has flexibility. It is possible to obtain a connector that is characterized by being

[0007]

[Action]

 The conductors are fixed to both ends of the conductor to prevent the long conductors arranged in parallel from being separated. By thus insulating the intermediate conductor portion between the insulators at both ends with an insulating tape or insulating paint, the intermediate conductor portion between these insulators is not impaired in flexibility and A short circuit due to contact between other conductors in the section and neighboring intermediate conductor sections is easily and reliably prevented.

Further, since the insulating paint or insulating tape applied or attached is very thin, it is possible to cope with a narrow pitch.

【Example】

 A connector according to an embodiment of the present invention will be described below. 1 (a), 1 (b), 1 (c) and 2 show a connector according to an embodiment of the present invention. This connector has a long conductor 11 in which a plurality of conductors are arranged in parallel, and two insulators 2a and 2b made of hard synthetic resin or the like, which are fixed to both ends of the conductor 11 in the longitudinal direction. ing. The insulators 2a and 2b are held on the conductor 11 by, for example, insert molding. As another holding means, the end portions of the conductor 11 may be pressed into the insulators 2a and 2b, or may be attached to the conductor 11 by bonding.

The ends of the conductors 11 extending outward from the insulators 2a and 2b are terminal portions that are soldered and connected to a printed circuit board or the like. Further, the intermediate conductor portion 12 between the insulators 2a and 2b has a bendable flexibility. An insulating tape 3, which is an insulating member, is attached to the intermediate conductor portion 12 located between the insulators 2a and 2b. This insulating tape 3 also has flexibility like the intermediate conductor portion 12.

The insulating tape 3 may be a known one in which a suitable adhesive or adhesive is applied to the surface of the insulating resin film to which the tape is attached. It is preferable that the insulating tape 3 be attached to both surfaces of the intermediate conductor portion 12, that is, to both the I surface and the II surface in FIG. 1B, but there is a possibility that another intermediate conductor portion 12 or the like may come into contact. It only needs to be attached on at least one side that has By attaching the insulating tape 3 in this way, necessary insulation can be achieved in the intermediate conductor portion 12, and even when the intermediate conductor portion 12 is bent due to the adhesive force of the insulating tape 3, the intermediate conductor portion 12 can be bent. The spacing between is kept constant.

The insulating tape 3 may be attached to the intermediate conductor portion 12 either before or after the insulators 2 a and 2 b are attached to both ends of the conductor 11 by insert molding or press fitting. Both ends of the insulating tape 3 may be recessed into the insulators 2a and 2b as shown in FIG. 3, or may not be recessed as shown in FIG.

FIGS. 5 and 6 show a connector according to another embodiment of the present invention, in which an insulating paint 4 as an insulating member is applied to the intermediate conductor portion 12 between the insulators 2a and 2b for insulation. This is an example of forming a film and performing insulation. The insulating paint 4 is applied to the outer periphery of each intermediate conductor portion 12.

Further, FIGS. 7A to 7E show an example in which the two printed circuit boards 5a and 5b are flexibly connected. That is, FIG. 7A shows a case where the horizontally arranged printed circuit boards 5a and 5b are connected by a connector. FIG. 7B and FIG. 7C show a case where the printer circuit boards 5a and 5b arranged at right angles are connected by a connector. Further, FIG. 7D shows a case where the printed circuit boards 5a and 5b arranged in parallel are connected to each other with a connector inside. FIG. 7E shows a case where these are connected to each other on the outside of the printed circuit boards 5a and 5b by connectors.
