Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a connector for connecting an FPC (flexible printed circuit board).

[0002]

[Prior Art]

 In electronic equipment, many electronic parts are housed in a narrow housing due to recent improvements in performance. These electronic components are usually used by being mounted on an FPC by soldering, etc., and a structure in which another FPC is placed on such an FPC is also widely used. Each of these FPCs has an electronic part on one side and a conductive pattern part on the other side for connecting these electronic parts in a predetermined order. The contact terminal of the connector is brought into contact with the conductive pattern portion at one end of the connection and the connection is made.

By the way, the conductive pattern portion of the FPC may face upward or downward depending on the wiring condition in the device. Correspondingly, the connectors attached to them also have a structure in which the contact terminals are connected on the upper surface or the lower surface of the FPC, so that connectors with both contact structures are required. Conventionally, both of these connectors are made separately.

A conventional example of such an FPC connecting connector is shown in FIG. In this example, the bottom surface is connected, and one end of the FPC 6 is inserted from the insertion recess 7 formed by mounting the slide insulator 41 on the base insulator 31. Then, the contact terminal 1a of the contact 1 comes into contact with the conductive pattern portion 6a formed on the lower surface of the FPC 6 from below to make a connection. Further, this connector is placed on a device housing or another supporting substrate 8 and is fixed to the supporting substrate 8 by screwing or the like by using a holddown 21 fixed to the connector. Also, the FPC 6 connected to the connector is fixed on the support substrate 8.

FIG. 9 shows an example of the upper surface connection, and one end of the FPC 6 is inserted from an insertion recess 7 formed by mounting the slide insulator 41 on the base insulator 31 as in the above. The contact terminal 5a of the contact 5 is brought into contact with the conductive pattern portion 6a formed on the upper surface of the FPC 6 from above to make a connection. Further, the connector and the FPC 6 connected to the connector are fixed on the support substrate 8 by the holddown 21 fixed to the connector, as in the example of FIG.

[Problems to be solved by the device]

 By the way, in the above-mentioned conventional connector, since the connectors for contacting the upper surface and the lower surface are separately configured as separate parts, even if the usage is the same and the number of contacts is the same, Different types of parts must be prepared, and different manufacturing dies are required for each, which poses an obstacle to cost reduction.

In view of the above-mentioned conventional drawbacks, the present invention has an object to provide an FPC connection connector capable of coping with both upper surface and lower surface contact with the same component parts.

[0008]

[Means for Solving the Problems]

 According to this invention, a plurality of contact mounting protrusions are formed in a comb shape and a base insulator is mounted on the base insulator to form an FPC (flexible printed circuit board) insertion recess together with the base insulator. A slide insulator having a lid piece; a plurality of contacts that are inserted into the base insulator and connected to a conductive pattern portion formed on one of the upper and lower surfaces of the FPC in the insertion recess; The base insulator and the slide insulator are provided on both sides of the base insulator for fixing the connector, and the base insulator and the slide insulator respectively have a locking portion and a locking projection for locking the mounting between them. Based on whether the conductive pattern portion of the FPC is above or below the base pattern. FPC connector being characterized in that so as to vary the contact is obtained with the said slide insulator and regulator upside down.

[0009]

[Action]

 The locking portion holds the locking between the base insulator and the slide insulator, and the holddown direction can be changed appropriately according to the upper surface contact or the lower surface contact of the FPC. As a result, the same configuration can be obtained. It is possible to construct the connector for both the upper surface contact and the lower surface contact for the FPC with the components.

[0010]

【Example】

 Examples will be described below. FIG. 1 shows a connector of the embodiment in the case of bottom contact. As shown in FIG. 1, this connector has a conductive contact 1 having contact terminals 1a and 1b, an insulating base insulator 3 into which the contact 1 is inserted, and a connector placed on another supporting substrate 8. It is composed of a substantially L-shaped holddown 2 for fixing, and an insulating slide insulator 4 having locking projections 4a, 4a formed at both ends.

The base insulator 3 is hollow, and a large number of comb-teeth-shaped protrusions 3 a and 3 b are formed on the lower and upper walls of the base insulator 3 for inserting the contacts 1. The contact terminal 1a of the contact 1 and the fitting piece 1d are fitted and inserted between the protruding sides 3a and 3b, respectively.

Engagement pieces 3 c are provided at both ends of the base insulator 3, respectively. Between the engaging piece 3c and the main body of the base insulator 3, there is a space for mounting the holddown 2 and a projection (not shown) that can be inserted into the upper engaging groove 2a of the holddown 2. It is provided, and the holddown 2 is held by the space and the protrusion. The lower side 2b of the holddown 2 is placed on another supporting substrate 8 and fixed by screwing or the like.

The engagement piece 3c is also formed with two tapered locking portions 3d. These constitute a locking mechanism together with the locking projections 4 a of the slide insulator 4. Moreover, a lid piece 4b is formed on the slide insulator 4 so as to face the base insulator 3.

In the connector having the above structure, the holddown 2 is attached to the base insulator 3 from the state of FIG. 1, the slide insulator 4 is slid toward the base insulator 3, and the locking projections 4a and 4a are formed on the base. FIG. 2 shows a state in which the connector is assembled by engaging with the engaging portions 3d, 3d of the insulator 3 and its cross section is shown in FIG. The lower side 2b of the holddown 2 projects from both ends of the connector. FIG. 4 is a view of the engagement structure between the engagement piece 3c and the locking projection 4a as seen from above.

As is apparent from FIG. 3, the fitting piece 1 d of the contact 1 is fitted between the base insulator 3 and the lid piece 4 b of the slide insulator 4. Moreover, an insertion recess 7 is formed between the protrusion 3a of the base insulator 3 and the lid 4b of the slide insulator 4, and the contact terminal 1a of the contact 1 is projected into this insertion recess 7. . Then, in this state, the FPC 6 is inserted into the insertion concave portion 7 with the conductive pattern portion 6a facing down, so that the conductive pattern portion 6a and the contact terminal 1a are brought into contact with each other for connection.

FIG. 5 shows a contact of the embodiment in the case of the upper surface contact. In this state, the base insulator 3 and the slide insulator 4 are turned upside down in the state of FIG. The same as in the case of the bottom surface contact described above, except that the contact terminal 5a and 5b are respectively provided at the upper end and the lower end, which are opposite to the contact 1.

Then, in this configuration, the slide insulator 4 is slid toward the base insulator 3 from the state shown in FIG. 5, and the locking projections 4a and 4a are locked to the locking portions 3d and 3d of the base insulator 3. The assembled state of the connector is shown in FIG. 6, and its cross section is shown in FIG. Even in this state, the lower side 2b of the hold down 2 is projected from both ends of the connector as in the above case.

Further, as shown in FIG. 7, the fitting piece 5 d of the contact 5 is fitted between the base insulator 3 and the lid piece 4 b of the slide insulator 4. On the other hand, the contact terminal 5a of the contact 5 is projected into the insertion recess 7 formed between the protruding piece 3a of the base insulator 3 and the lid piece 4b of the slide insulator 4. Then, in this state, if the FPC 6 is inserted into the insertion recess 7 with the conductive pattern portion 6a facing upward, the conductive pattern portion 6a and the contact terminal 5a come into contact with each other to make a connection.
