BACKGROUND OF THE INVENTION The present invention relates to a connector, and in particular,
The present invention relates to a connector for directly connecting a wiring portion such as a printed circuit board and a cable.

[0002]

2. Description of the Related Art Generally, as a connector, a connector (for example, an FPC connecting connector) for connecting a printed circuit board in an electronic device and a cable such as FPC or FFC is known. With reference to FIG. 6, the FPC connection connector 11 includes a base insulator 12, and the base insulator 12 holds contacts (not shown in FIG. 6). The contact has an FPC connection end and a printed circuit board connection end. Further, a reinforcing plate (not shown in FIG. 6) is held by the base insulator 12, and the printed board (not shown) is held by the reinforcing plate.
Is fixed to the printed circuit board connection end. A slide insulator 13 is arranged on the FPC connection end side, and the slide insulator 13 is slidable with respect to the base insulator 12 in a direction indicated by a solid arrow. FP
The C14 has a predetermined copper foil pattern 15 formed at one end thereof and a contact contact portion 16 at the other end.

By the way, generally, when the FPC connecting connector is used, it is necessary to perform an electrical inspection between the FPC connecting connector and the printed circuit board. Referring to FIG. 7, when performing an electrical inspection between the FPC connection connector and the printed circuit board, first, the FPC 14 is connected to the connector 11
Connect to. That is, after inserting the contact contact portion 16 into the FPC connection end, the slide insulator 13 is slid in the direction indicated by the solid line arrow to move the FPC 14 into the connector 1.
Connect to 1. Next, with reference to FIG. 8, an electrical inspection is performed using the inspection jig 18 having the electrical inspection probe pin 17. In the inspection, the probe pin 17 for electrical inspection is brought into contact with the copper foil pattern 15.

[0004]

As described above, in the conventional FPC connecting connector, when the FPC 14 is electrically tested between the FPC connecting connector and the printed circuit board,
It is necessary to perform the operation while being connected to the C connection connector 11. In other words, open the slide insulator 13,
It is necessary to insert the FPC 14 into the FPC connection end and then lock the slide insulator 13. And
After connecting the FPC 14 to the connector 11, the inspection probe pin 17 is brought into contact with the copper foil pattern 15. Therefore, when the probe pin 17 for inspection after the inspection is separated from the copper foil pattern 71, the soft solder plating on the copper foil pattern 17 is often damaged. As a result, copper foil pattern 1
In 7, the plating was peeled off like a whiskers (that is, a peeling portion was generated), and this peeling portion contacted the adjacent pattern,
There is a problem of short circuit. An object of the present invention is to provide a connector that can simplify the inspection process and prevent damage to the copper foil pattern.

[0005]

According to the present invention, a base insulator having a first connecting end portion and a second connecting end portion, and a base insulator held by the base insulator,
And a contact having a plurality of contact bodies extending to the second connection end portion, the base insulator includes the first connection end portion and the second connection end portion. The base insulator has partition walls for forming a plurality of accommodating chambers that extend in between and into which the respective contact bodies are press-fitted, and further, the base insulator has the plurality of contact bodies on the first connection end side. A connector is obtained, which has a notch portion extending in a transverse direction to expose the contact body as an exposed portion, and a groove portion is formed in the exposed portion.

[0006]

According to the present invention, the base insulator is formed with a notch extending in a direction traversing the plurality of contact bodies so that a part of the contact body is exposed as an exposed portion on the first connection end side. Since the groove is formed in the exposed part, when performing the electrical inspection between the printed circuit board and the connector, the probe pin is guided into the groove by simply abutting the probe pin on the exposed part, and the electrical inspection is not performed. Even in the inside, the state in which the probe pin is securely held in the groove can be maintained. Further, in the present invention, since each contact body is press-fitted into the storage chamber defined by the partition wall,
When performing an electrical inspection, for example, a short circuit with an adjacent contact body or the like can be prevented.

[0007]

EXAMPLES The present invention will be described below with reference to examples. First, with reference to FIG. 1, the same components as those in FIG. 6 are designated by the same reference numerals, and the description thereof will be omitted. When connecting the FPC 14 (that is, when mounting the FPC 14) with the connector 20 shown in FIG. 1, first, the slide insulator 13 is opened as shown in FIG. Insert the contact part). After that, slide the slide insulator 13 in the direction indicated by the solid arrow to move the FPC 1
4 to the connector 20. In the connector 20, FIG.
As shown in, the base insulator 12 is formed with a notch portion (notch groove) 12a extending in the longitudinal direction on the printed circuit board connection end side. As a result, when the printed circuit board connecting end is viewed from the upper side in the figure, the contact 21 is exposed at the printed circuit board connecting end.

Here, referring also to FIGS. 3 and 4, in the base insulator 12, from the printed circuit board connecting end to the FP.
A contact storage chamber extending to the C connection end is formed,
The storage section is divided into a plurality of contact storage sections by a plurality of partition walls 12b arranged at equal intervals. A contact body 22 is press-fitted into each contact storage portion, and each contact body 22 is connected to the printed circuit board connecting end by F
It extends to the PC connection end. A contact is formed by these contact bodies 22.

As shown in FIG. 3, in the present invention, the upper surface of each contact member 22 is located above the upper surface of the partition wall 12b, and the upper surface of each contact member 22 extends downward.
A V-shaped groove portion 22a is formed. The bottom surface of each V-shaped groove portion 22a is located below the top surface of the partition wall 12b.

When conducting an electrical inspection between the connector and the printed circuit board, as shown in FIG. 4, the probe pin 17 is brought into contact with the upper surface of each contact body 22 through the notch groove 12a. At this time, since the V-shaped groove portion 22a is formed on the upper surface of each contact body 22, the probe pin 17 is inserted into the V-shaped groove portion 22a. Moreover, since each V-shaped groove portion 22a is isolated (insulated) by the partition wall 12b, even if all the contact bodies 22a are brought into contact with the probe pins 17 at the same time, a short circuit or the like does not occur.

By the way, as shown in FIG. 5, each contact body 22 may be press-fitted into the contact storage chamber so that the upper surface of each contact body 22 is located below the upper surface of the partition wall 12b. In this case, when viewed from above,
Since the contact body 22 is completely embedded in the partition wall 12b, the contact body 22 can be reliably insulated from the adjacent contact bodies 22. As a result, it is possible to reliably prevent the probe pin 23 from accidentally coming into contact with other than the intended contact body 22a.

[0012]

As described above, according to the present invention, in the connecting portion side of the wiring portion (for example, the printed circuit board), a plurality of contact bodies are crossed so that a part of the contact body is exposed as an exposed portion. Since the notch that extends is formed in the base insulator and the groove is formed in this exposed part, when the electrical inspection between the printed circuit board and the connector is performed, the probe pin can be simply contacted with the exposed part. Is guided to the groove portion, and there is an effect that the state in which the probe pin is securely held in the groove portion can be maintained even during the electrical inspection. Further, since the probe pin can be directly brought into contact with the contact, the inconvenience of peeling off the copper foil pattern does not occur. Further, since it is not necessary to connect a cable such as an FPC, the inspection can be easily performed. In addition, since each contact body is press-fitted into the storage chamber defined by the partition wall, there is an effect that, for example, a short circuit with an adjacent contact body can be prevented when performing an electrical inspection.
