DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector.

[0002]

2. Description of the Related Art FIG. 4 shows a conventional connector. This connector is used for flexible printed wiring boards, tape wires,
CIC (Conductive Ink Circuit)
t) or other ZIF (Ze) for connecting a flexible cable 3
ro Insertion Force) type connector, which includes a housing 11 for holding a plurality of terminal members 13, and a slider portion 14.

The housing 11 has a holding portion 11a into which a holding piece 13a formed on the terminal member 13 is fitted, and a contact 13 between the terminal member 13 and the flexible cable 3.
a space 15 for accommodating the b.
The protrusion 14a formed on the slider 14 is inserted.

The slider portion 14 has a holding plate 14c having an insertion opening 14b into which the flexible cable 3 is inserted, and the projecting portion 14a projects from the back surface of the holding plate 14c. The protruding portion 14a is arranged so as to face the contact surface 13c of the terminal member 13 when inserted into the space 15 of the housing 11.

Under such a configuration, the flexible cable 3
In order to mount the flexible cable 3, the flexible cable 3 is inserted into the space 15 of the housing 11 from the insertion opening 14b, and then the slider 14 is pushed downward, and the contact portion 7 of the flexible cable 3 is It is pressed against the surface 13c side to make pressure contact.

[0006]

However, in the above conventional example, the flexible cable 3 is configured to be inserted from the gap 15a between the projecting portion 14a and the contact surface 13c of the terminal member 13, and the slider portion 14 is unlocked. Since the flexible cable 3 is not completely retracted from the insertion path even in the locked state, the flexible cable 3
The contact portion 7 of the flexible cable 3 comes into sliding contact with the contact surface 13c of the terminal member 13 when the cable is inserted into and detached from the connector. However, there is a disadvantage that the life is shortened.

An object of the present invention is to provide a connector which has been made to solve the above-mentioned disadvantages and can extend the life of a flexible cable.

[0008]

The object of the present invention is to provide, as shown in FIG. 1, a connecting lead 2 to a printed board 1 at one end and a contact 4 with a flexible cable 3 at the other end. A body part 6 for holding a plurality of terminal members 5,
A slider portion 8 that is vertically slidably mounted on the main body portion 6 and elastically deforms the terminal member 5 by the vertical sliding operation to press the contact 4 against the contact portion 7 of the flexible cable 3; The inclined wall surface 9 accommodates the contact 4 of each terminal member 5 and presses the back surface of the contact 4 of each terminal member 5 with the sliding operation downward to press the contact 4 against the flexible cable 3.
This is achieved by providing a connector in which a receiving recess 10 having a recess is provided.

[0009]

Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

FIGS. 1 to 3 show an embodiment of the present invention. The connector according to this embodiment is formed of a box-shaped body made of an insulating material, and has an opening at an upper part;
And a slider portion 8 which covers the opening of the flexible cable 3 and has an insertion port 8a for the flexible cable 3.

A triangular rising portion 6a is formed on the upper end edge of the main body 6 so as to gradually increase toward the inside in order to smoothly engage with the slider portion 8.
Is provided. The guide 6 is provided on the side wall of the main body 6.
The guide portion 6b is provided with a locking projection 6c for locking a slider portion 8 described later.

Further, as shown in detail in FIG. 2, a terminal member 5 is fixed in the main body 6. The terminal member 5 has a contact 4 with the flexible cable 3 at one end and a joining lead 2 at the other end.
a is press-fitted and fixed.

The terminal member 5 is supported in a cantilever shape upward from the bottom wall of the main body 6 to enable displacement of the contact 4 formed at its free end. Further, a bulge 4a is provided on the back side of the contact 4.

On the other hand, the slider portion 8 has a leg 8c hanging down from both ends of a pressing plate 8b for closing the opening of the main body 6, and a pressing portion 8d of the contact 4 is provided at the center of the pressing plate 8b.
The leg pieces 8c, 8c are
Are slidably mounted along the two guide portions 6b. Further, the peripheral edge of the pressing plate 8b is formed so as to correspond to the shape of the upper edge of the main body 6 described above. Further, a locking recess 8e for locking to the locking projection 6c of the guide portion 6b is provided on the inner wall of the leg 8c.

The pressing portion 8d is formed so as to be able to fit into the opening of the main body portion 6, and the accommodating concave portions 10 are provided at the same pitch as the arrangement pitch of the terminal members 5. The wall surface of the housing recess 10 is an inclined wall surface 9 that is inclined toward the contact 4 as going upward from below.

The contact 4 of the terminal member 5 is accommodated in the accommodating recess 10 of the slider portion 8. In the accommodated state, the terminal member 5 causes the bulging portion 4a to abut on the inclined wall surface 9 due to its elasticity. The contact 4 is formed so as to move following the vertical operation of the slider portion 8.

The flexible cable 3 used in this embodiment is a flexible printed wiring board, a tape wire, a CIC, or the like, and a contact portion 7 having an exposed conductor is formed at the end inserted into the connector. Have been.

Therefore, in this embodiment, the attachment of the flexible cable 3 to the connector is performed as follows. That is, first, as shown in FIGS. 2 (b) and 3 (b), the slider portion 8 is moved upward to a released state,
After inserting the contact portion 7 of the flexible cable 3 from the insertion opening 8a, the pressing plate 8b is pushed downward, and the leg 8
The locking recess 8e of FIG. 3c is locked to the locking projection 6c of the main body 6 side.

The downward movement of the slider portion 8 causes the inclined wall surface 9 of the housing recess 10 to move downward, and
The space for accommodating gradually decreases. In the locked state of the slider portion 8, as shown in FIGS. 2A and 3A, the bulging portion 4 a of the terminal member 5 is formed by the inclined wall surface 9.
Is pressed, a part of the contact 4 protrudes from the accommodation recess 10, and the contact portion 7 of the flexible cable 3 is
The two are connected by pressing against each other.

Further, when the flexible cable 3 is separated from the connector, as shown in FIGS. 2 (b) and 3 (b), the operation is the opposite of the connection method, that is, the slider portion 8 is moved upward. In this state, since the contact 4 is completely housed in the housing recess 10,
When the flexible cable 3 is inserted and removed, the work can be performed without cutting the pattern of the contact portion 7.

[0021]

As is apparent from the above description, according to the present invention, the life of the flexible cable can be extended.
