DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector for connecting a flexible printed circuit (FPC).

[0002]

2. Description of the Related Art A conventional FPC connector disclosed in Japanese Utility Model Laid-Open No. 5-6759 will be described with reference to FIGS.

[0003] A conventional FPC connection connector 11 includes a number of contacts 12, a base insulator 13, and a slide insulator 14.

A large number of substantially U-shaped contacts 12 are fixed to the base insulator 13 at predetermined intervals in a direction perpendicular to the paper surface.

[0005] The order in which the FPC 15 is fitted to the FPC connector 11 will be described. First, in the state of FIG.
When the FPC 15 is moved in the direction of the arrow and its tip is inserted between one piece 12A and the other piece 12B of the contact 12, the state shown in FIG. 6 is reached. Next, the slide insulator 14 is moved in the direction of the arrow, and
When the FPC 15 shown in FIG.

[0006]

In the conventional connector for FPC connection, when the number of contacts, that is, the number of cores increases, the insertion force of the slide insulator must be increased. Also, it was necessary to make one piece of the contact and the other piece elastic, so that the size of the contact had to be increased. Therefore, the structure of the conventional connector for FPC connection hinders a low profile (low profile).

Accordingly, the present invention improves the drawbacks of the above-mentioned conventional FPC connection connector, and provides an FPC connection connector which has a low profile and can be fitted with a weak operating force even with a large number of cores. What you want to do.

The present invention employs the following means to solve the above-mentioned problems.

1. An insulator, a contact fixed to the insulator, and having a substantially inverted Ω-shaped contact portion, and a substantially U-shaped portion corresponding to the substantially inverted Ω-shaped contact portion, and molded from a material having elasticity. A contact pressure generated when the cover is pressed by the substantially inverted Ω-type contact portion and bent, with an FPC sandwiched between the substantially inverted Ω-type contact portion and the substantially U-shaped portion. As a result, the F
An FPC connector for connecting a PC to the contact.

[0010] 2. 2. The FPC connection according to claim 1, wherein a substantially U-shaped portion corresponding to the substantially inverted Ω-shaped contact portion on the FPC and opposite to the substantially U-shaped portion of the cover is formed in advance. connector.

3. 2. The FPC connection connector according to the item 1, wherein a pattern at an intermediate portion of the FPC is exposed and connected to the contact.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS.

An FPC connection connector 1 according to the present embodiment.
Is composed of a number of contacts 2 having no elasticity, insulators 3, a cover made of elastic resin, and a housing 6 made of resin.

A large number of contacts 2 having substantially inverted Ω-type contact portions 2a are fixed to the insulator 3 at predetermined intervals in a direction orthogonal to the paper surface. Solder portions 2b are formed on both sides of each contact 2. The cover 4 has a substantially U-shaped portion 4a corresponding to the substantially inverted Ω-shaped contact portion 2a of each contact 2.

FP fitted to FPC connection connector 1
C5 corresponds to the substantially inverted Ω-type contact portion 2a, and
A substantially U-shaped portion of the cover 4 opposite to the substantially U-shaped portion 4a.
The part 5a is formed in advance.

The order in which the FPC 5 is fitted to the FPC connector 1 will be described. First, the insulator 3 to which the many contacts 2 are fixed in the state of FIG. 2 is housed in the housing 6 as shown in FIG. Next, the soldering portion 2b of each contact 2 is connected to a printed circuit board (not shown).
Fixed to. Subsequently, the substantially U-shaped portion 5 a of the FPC 5 is inserted into the substantially inverted Ω-shaped contact portion 2 a of each contact 2. Finally,
The substantially U-shaped portion 4a of the cover 4 is replaced with the substantially U-shaped portion 5a of the FPC 5.
To the fitting state shown in FIG. In this state, the cover 4 serves as the substantially reverse Ω-type contact portion 2a of the contact 2.
Due to the contact pressure that occurs when it is pressed and bent
The FPC 5 and the contact 2 are connected.

In the FPC connector 1, the cover 4
Is fitted to many contacts 2, instead of fitting the entire cover 4 to many contacts 2 at once, using the elasticity of the cover 4 in the width direction (the pitch direction of many contacts 2). Since the cover 4 and the large number of contacts 2 can be sequentially fitted little by little from an arbitrary position, even if the number of contacts is increased, the fitting can be performed with a weak operating force.

The contact 2 of the FPC connector 1 can be connected not only to the end of the FPC 5 but also to an intermediate portion. That is, as shown in FIG. 4, by exposing the signal pattern at the intermediate portion of the FPC 5 to be connected, the connection can be made to the contact 2.

[0019]

As is apparent from the above description, the present invention has the following advantages.

1. Since a cover having elasticity is used, the contact does not need to have elasticity, and since the cover is slightly deformed in the thickness (height) direction,
Both the cover and the contact can be formed thin.
Further, since the substantially U-shaped portion of the cover is inserted into the substantially inverted Ω-shaped contact portion of the contact, the entire connector has a low profile.

2. Using the elasticity in the width direction of the cover,
Since the cover and a large number of contacts can be sequentially fitted little by little from an arbitrary position, even if the number of cores is increased, the fitting can be performed with a weak operating force.

3. By exposing the signal patterns and connecting the contacts to the contacts, not only the ends of the FPC but also the intermediate portions of the FPC can be fitted to the connector.
